metallwerke renner 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 the designed mechanical parts, the required fixture can be obtained. Hydraulic fixtures ensure accurate positioning and secure clamping of the workpiece at the specified position, and can reduce vibration and deformation during machining through floating support. They can also use automatic control to press down and lift the 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.

An electromagnetic chuck is an electromagnetic fixture that secures the workpiece being machined using the suction force generated by the chuck body when 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.

metallwerke renner fixture features

Mechanical grippers commonly use compressed air as the power source, realizing finger movement through a transmission mechanism. 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. In this type of gripper, the two fingers perform parallel opening and closing movements 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 trajectories of the two fingers in this type of gripper are 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 roller mounted at its end moves within the cam slot, realizing the parallel clamping movement 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 rack on the fingers performs linear motion, thereby causing the two fingers to open and close in parallel to clamp the workpiece.

metallwerke renner 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 objects allowed to be lifted under specified working conditions, also known as the rated lifting capacity. Generally, for cranes equipped with electromagnetic chucks, 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 workbench using T-shaped blocks and screws. Connect the DC power supply and ground wire from the machine tool, then precision grind the upper surface of the chuck once to ensure the parallelism between the upper surface and the bottom surface. When holding 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.
