German DIATEST workpiece fixtures DIATEST model DIATEST price

DIATEST workpiece fixtures use hydraulic components to replace mechanical parts, achieving automatic positioning, support, and clamping of the workpiece through hydraulic control. They offer advantages such as high clamping force, reliable clamping, stable operation, and ease of use. They are currently widely used in scenarios such as CNC machine tools, machining centers, and automated production lines. By assembling the selected hydraulic components with the designed mechanical parts, the required fixture can be obtained. Hydraulic fixtures ensure accurate positioning and secure clamping of the workpiece at specified positions, and can reduce vibration and deformation during machining through floating supports. They can also utilize automatic control to press down and lift the pressure plates, clearing the clamping position during machining. Hydraulic fixtures can withstand large cutting forces during rough machining, ensure accurate positioning during precision machining, and perform support, clamping, and quick release tasks that manual fixtures cannot accomplish.

DIATEST workpiece fixture types

1) Standard rectangular electromagnetic chuck Application: Rectangular table surface grinders. 2) High-power electromagnetic chuck Application: Milling machines, planers, machining centers. 3) Fine-pole electromagnetic chuck Application: Rectangular table surface grinders, milling machines. 4) Multi-functional high-power electromagnetic chuck Application: Rectangular table surface grinders. 5) Rotary electromagnetic chuck Application: Various surface grinders. 6) Electromagnetic chuck for tool grinding Application: Tool grinding machines. 7) Circular electromagnetic chuck (concentric type) Application: Circular table surface grinders. 8) Circular electromagnetic chuck (radial pole type) Application: Circular table surface grinders. 9) Circular electromagnetic chuck (plum blossom pole type) Application: Circular table surface grinders. An electromagnetic chuck is an electromagnetic fixture that secures the workpiece being processed by generating suction force in the chuck body after the electromagnetic coil is energized. The electromagnetic chuck consists of several parts, including the iron core, coil, faceplate, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck.

DIATEST workpiece fixture features

Mechanical grippers commonly use compressed air as the power source, realizing finger movement through transmission mechanisms. Based on the different motion trajectories of the fingers when clamping the workpiece, mechanical grippers are classified into: 1) Arc opening/closing type: Driven by 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: The two fingers of this gripper move in 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 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, the rollers mounted at 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.

DIATEST workpiece fixture usage

With the continuous development of China's industry, electromagnetic chucks are increasingly widely used in industrial production. The most important aspect of an electromagnetic chuck is its parameters; among the performance parameters, the lifting capacity and its working class are the most critical. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight of the load allowed to be lifted under specified operating conditions, also known as the rated lifting capacity. Generally, for cranes equipped with an electromagnetic chuck, the lifting capacity should also include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting threaded holes on both sides; during installation, T-shaped screws can be screwed in for lifting. They are fixed to the worktable using T-shaped blocks and screws. Connect the DC power supply and ground wire from 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 adsorbing workpieces, 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. Before use, the surface of the electromagnetic chuck should be wiped clean to avoid scratches. Severe impacts are prohibited to prevent affecting accuracy. After use, it should be cleaned and coated with anti-rust oil to prevent corrosion. When using the electromagnetic chuck independently, a ground wire must be connected to prevent electric shock due to leakage.
