German maxion workholding fixtures maxion model maxion price

maxion workholding 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 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 locations, reduce vibration and deformation during machining through floating supports, and utilize automatic control of pressure plate clamping and lifting 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.

1) Positioning elements: These contact the positioning reference of the workpiece to determine its correct position in the fixture, thereby ensuring the correct relative position of the workpiece with respect to the tool and machine tool movements during machining. 2) Clamping device: Used to clamp the workpiece, keeping it in the established position within the fixture during cutting. As shown in Figure 6-1, this includes nut 5 and open washers. 3) Tool-setting and guiding elements or devices: These elements ensure the correct position between the workpiece and the tool. Elements used to determine the correct position of the tool before machining are called tool-setting elements, such as tool-setting blocks. Elements used to determine the tool position and guide the tool during machining are called guiding elements. 4) Connecting elements: Elements that connect the fixture to the machine tool, ensuring the mutual positional relationship between the machine tool and the fixture. 5) Fixture body: The base component used to connect or fix various elements and devices on the fixture into a single unit. It connects and aligns with relevant parts of the machine tool, giving the fixture a definite position relative to the machine tool. 6) Other elements and devices: Some fixtures require indexing mechanisms based on workpiece machining requirements, and milling machine fixtures also require locating keys, etc. Not all of these components are indispensable for every type of machine tool fixture, but any fixture must have positioning elements and a clamping device. They are key to ensuring workpiece machining accuracy, with the aim of accurately positioning and securely clamping the workpiece.

Mechanical grippers commonly use compressed air as the power source, achieving 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 trajectory of the two fingers in this type of gripper is linear, and the clamping surfaces of the two fingers remain parallel. A cam mechanism is used to achieve 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.

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 these performance parameters, the lifting capacity and duty 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 operating conditions, also known as the rated lifting capacity. Generally, for cranes equipped with an electromagnetic chuck, the lifting capacity should 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 and 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.
