German SIEMENS workpiece fixtures SIEMENS model SIEMENS price

SIEMENS workpiece fixtures are any tools with specific functions connected to the edge (joint) of a robot. This may include robot grippers, robot tool changers, robot collision sensors, robot rotary connectors, robot pressure tools, compliance devices, robot spray guns, robot deburring tools, robot arc welding torches, robot electric welding torches, etc. Robot end-effectors are generally considered peripheral equipment, accessories, tools, or arm-end tools (EOA) of the robot. Key elements: mechanism type, gripping method, gripping force, drive unit and control object characteristics, mass, shape, center of gravity position, dimensions, dimensional tolerances, surface condition, material, strength; operating parameters: operating space environment, operating accuracy, operating speed and acceleration, clamping time.

SIEMENS workpiece fixture structure

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 between the workpiece and the tool/machine tool motion 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, such as nut 5 and open washer. 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; milling machine fixtures also require positioning keys, etc. Not all these components are indispensable for every machine tool fixture, but any fixture must have positioning elements and clamping devices. They are key to ensuring workpiece machining accuracy, with the aim of accurately positioning and firmly clamping the workpiece.

SIEMENS workpiece fixture process

The electromagnetic chuck consists of a base housing, iron core, coil, panel, and junction box. Its manufacturing process is as follows: 1) Select suitable materials for welding or casting the base housing. 2) Install the iron core onto the base housing according to the type of chuck. 3) Wind the coil with the corresponding number of turns and technical parameters, dry it, and fit it onto the iron core. 4) Pour asphalt or other waterproofing materials into the interior of the base housing. 5) Manufacture the panel and install it together with the base housing part. Electromagnetic chucks use DC power supply and feature stability, strong suction, and low residual magnetism. Electromagnetic chucks can be classified into standard suction chucks and high-power chucks. Standard suction chucks have a suction force of 10-12 kg/cm², while high-power electromagnetic chucks have no less than 14 kg/cm². Based on application, they can be divided into electromagnetic chucks for grinders, electromagnetic chucks for milling and planing machines, electromagnetic chucks for knife grinding machines, etc.

SIEMENS workpiece fixture selection and 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 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.
