German KUSO workholding fixtures KUSO model KUSO price

KUSO workholding fixture is a machine tool accessory produced based on the electromagnetic principle: energizing the internal coil generates magnetic force, which passes through the magnetically conductive panel to firmly hold the workpiece in contact with the panel surface; de-energizing the coil causes the magnetic force to disappear, achieving demagnetization and allowing the workpiece to be removed. Its main applications include workpiece clamping during machining of ferrous workpieces on grinding machines, electromagnetic knife grinders, gantry milling machines, and gantry planers. Lifting threaded holes are provided on both sides of the rectangular electromagnetic chuck; during installation, T-head screws can be screwed in for lifting, and it is fixed to the worktable using T-head blocks and screws. Connect to the DC power supply and ground wire of the machine tool, then perform a precision grind on the upper surface of the chuck to ensure the parallelism between the upper surface and the bottom surface. When holding the workpiece, sufficient positioning holding force can be obtained by bridging two adjacent magnetic poles, allowing grinding operations to proceed. Magnetization and demagnetization of the workpiece can be controlled via the machine tool buttons.

KUSO workholding fixture classification

Due to the different operating characteristics and structural forms of various machine tools, different requirements are correspondingly placed on the structure of the fixtures used. According to the machine tool used, fixtures can be divided into: lathe fixtures, milling machine fixtures, drilling machine fixtures, boring machine fixtures, grinding machine fixtures, gear machine tool fixtures, and other machine tool fixtures. According to the clamping power source adopted by the fixture, they can be divided into: manual fixtures, pneumatic fixtures, hydraulic fixtures, pneumatic-hydraulic fixtures, electric fixtures, magnetic fixtures, vacuum fixtures, etc. Specialized classifications include general-purpose fixtures, special-purpose fixtures, general-purpose adjustable fixtures, group fixtures, modular fixtures, and pallet fixtures. A pallet fixture is a fixture used on automatic lines. This type of fixture not only serves to clamp the workpiece but also becomes integrated with the workpiece, moving from one station to the next along the automatic line for processing different operations.

KUSO workholding fixture features

Mechanical grippers commonly use compressed air as the power source, achieving finger motion through a transmission mechanism. Based on the different motion trajectories of the fingers when clamping the workpiece, mechanical grippers are divided into: 1) Arc opening/closing type: Under the drive of the transmission mechanism, the motion trajectory of the finger tips is an arc. This type of gripper has strict requirements on the dimensions of the clamped part of the workpiece; otherwise, it may cause abnormal workpiece status. 2) Arc parallel opening/closing type: In this type of gripper, the two fingers perform parallel opening and closing motions during operation, while the motion trajectory of the finger tips is an arc. The illustrated gripper shows two cases where a parallelogram transmission mechanism drives the parallel opening and closing of the fingers. 3) Linear parallel opening/closing type: The motion trajectory of the two fingers of this type of gripper is linear, and the clamping surfaces of the two fingers always remain parallel. A cam mechanism is used to achieve the parallel opening and closing of the two fingers. Inclined cam slots are machined on the sliding blocks of each finger. When the piston rod moves up and down, rollers mounted on its end move within the cam slots, achieving parallel clamping motion of the fingers. Alternatively, a rack-and-pinion mechanism is used: when the rack at the end of the piston rod drives the gear to rotate, the racks on the fingers move linearly, causing the two fingers to open and close in parallel to clamp the workpiece.

KUSO workholding fixture classification

The mechanical gripping end-effectors applied in loading and unloading industrial robots are mostly two-finger claw types. If classified by finger motion, they can be divided into translational and rotational types. If classified by mechanical clamping method, they can be divided into external clamping and internal expanding types. If classified by mechanical structural characteristics, they can be divided into electric (electromagnetic), hydraulic, and pneumatic types, as well as their combinations. 1) Pneumatic suction type: Pneumatic suction robot end-effectors use the suction force generated by negative pressure inside the suction cup to hold and move workpieces. The suction cup utilizes negative pressure formed in a bellows made of soft rubber or plastic to hold the workpiece. This type of robot end-effector is suitable for handling large, thin, low-rigidity metal or wooden sheets, paper, glass, and curved shells. Depending on the application, the end-effector can be designed with single, double, multiple, or specially shaped suction cups. Methods for generating negative pressure include: squeeze-type suction cups, airflow negative pressure suction cups, and vacuum pump exhaust suction cups. Squeeze-type suction cups: Squeeze-exhaust suction cups expel all air from the cup by downward squeezing force, creating a negative pressure state inside to hold the workpiece. Advantages include simple structure, light weight, and low cost. However, the suction force is not large, so they are mostly used for workpieces that are not too large in size, thin, and light. Airflow negative pressure suction cups: An airflow control valve injects compressed air from an air pump through a nozzle, forming a high-speed jet that removes air from the inner cavity of the suction cup, creating negative pressure to hold the object. This type is convenient and low-cost if compressed air is available at the job site. Vacuum pump exhaust suction cups: These utilize an electromagnetic control valve to connect the vacuum pump to the suction cup. When the control valve evacuates air, the air inside the suction cup cavity is removed, forming negative pressure to hold the object. Conversely, when the control valve connects the suction cup to the atmosphere, the suction cup loses suction force and releases the workpiece. The suction force of vacuum pump suction cups mainly depends on the size of the suction area and the degree of vacuum in the q cavity (referring to the thinness of the air inside). This type of suction cup is reliable and provides greater suction force, but requires a vacuum pump and airflow control system, resulting in higher costs. 2) Mechanical clamping type: Structure of a straight-bar dual-cylinder translational gripper. The gripper finger tips are installed on straight bars equipped with finger tip mounting seats. When pressurized gas enters the rod-side chambers of the two single-acting dual cylinders, the two pistons move toward the center, clamping the workpiece. When no pressurized gas enters, springs push the two pistons outward, releasing the workpiece. To ensure synchronous movement of the two pistons, a flow divider valve is installed in the cylinder intake line. This type of end-effector is used in loading and unloading assembly workstations.
