agro fixtures use hydraulic components to replace mechanical parts, achieving automatic positioning, support, and clamping of workpieces through hydraulic control. They offer advantages such as high clamping force, reliable clamping, stable operation, and ease of use, and are currently widely used in scenarios such as CNC machine tools, machining centers, and automated production lines. By assembling selected hydraulic components with designed mechanical parts, the required fixture can be obtained. Hydraulic fixtures ensure accurate positioning and secure clamping of workpieces at specified positions, can reduce vibration and deformation during machining through floating supports, and can utilize automatic control to press down and lift pressure plates to clear 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.

agro fixture requirements

Whether gripper-type or suction-type, robot end-effectors must also have the repeatability required for the task. The structure of the robot end-effector should be as simple and compact as possible, with light weight, to reduce the load on the arm. Dedicated robot end-effectors are more general in structure, simpler, but have high work efficiency and can perform various tasks. In contrast, "universal" end-effectors may have disadvantages such as complex structure and high cost. Therefore, it is recommended to design and use serialized and generalized dedicated robot end-effectors that can be quickly replaced. If an object has two opposing flat surfaces, a double-jaw parallel gripper can be used to solve dimensional deviation issues. For cylindrical objects, double-jaw grippers can also be used for clamping. It should be noted that containment or enveloping gripping requires less force.

agro fixture features

Mechanical grippers commonly use compressed air as the power source, achieving finger movement through transmission mechanisms. Based on the different motion trajectories of the fingers when clamping the workpiece, mechanical grippers are divided into: 1) Arc opening/closing type, where 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, where the two fingers of this gripper perform parallel opening and closing movements during operation, while the motion trajectory of the finger tips is an arc. The illustrated gripper uses a parallelogram transmission mechanism to drive the parallel opening and closing of the fingers in two situations. 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 opened on the sliding blocks of each finger. When the piston rod moves up and down, the roller installed at its end moves in the cam slot, achieving parallel clamping movement of the fingers. Using a rack and pinion mechanism, when the rack at the end of the piston rod drives the gear to rotate, the rack on the fingers performs linear motion, thereby causing the two fingers to open and close in parallel to clamp the workpiece.

agro fixture maintenance

1) Check before use whether the limit dimensions are still in the correct position. 2) If the stop pin wear exceeds tolerance, it can be repaired by grinding; if the baffle, pin, or locating taper pin wear exceeds tolerance, they can be reassembled, shifting the worn areas to continue use. 3) Apply anti-rust oil after use. Regular long-term lubrication can maintain the life of synchronous fixtures. Incorrect lubrication will lead to reduced clamping force, poor accuracy, wear, and jamming, so correct lubrication is essential. After machining, be sure to clean the body and slide ways of the synchronous fixture with an air gun or similar tool. During cleaning, remove the dust cover fixing screws and take off the dust cover, while extending the main jaws to the widest position to easily clean chips accumulated inside the fixture. To avoid reduced clamping force due to rust, use rust-preventive cutting oil. Remove the synchronous fixture every six months for a thorough cleaning (at least every two months when machining cast iron or copper products). Check parts for damage or wear, and replace with new ones immediately if severe. Lubricate thoroughly before assembly.
