German spmaier workpiece fixtures spmaier model spmaier price

spmaier workpiece fixtures are one of the actuators for vacuum equipment. Generally, using vacuum suction cups to grasp products is the most economical method. Vacuum suction cups come in various types; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for grasping products with rough surfaces, and polyurethane suction cups are highly durable. In addition, in actual production, if oil resistance is required for the suction cups, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing. Usually, to avoid scratching the surface of the product, it is best to choose bellows-type suction cups made of nitrile rubber or silicone rubber. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices.

spmaier Workpiece Fixture Classification

1) Lathe fixtures: Fixtures used on lathes to machine the internal and external rotary surfaces and end faces of workpieces are called lathe fixtures. Most lathe fixtures are installed on the spindle, and a few are installed on the saddle or bed. 2) Coordinate measuring machine (CMM) fixtures: Used on measuring machines, utilizing their modular support and reference devices to achieve flexible fixation of the measured workpiece. This device allows for automatic programming to support the workpiece and can establish an unlimited number of workpiece configuration reference points. Advanced specialized software can directly generate the workpiece clamping program within seconds based on the geometric data of the workpiece. 3) Industrial robot fixtures: All installed on industrial robots for use in industrial automation equipment, representing one of the new technologies in modern industrial automation. They mainly appear in modern industrial production in coordination with robots, with common applications including machine tool loading/unloading, workpiece palletizing/depalletizing, welding, and grinding in automated unmanned factories. 4) Milling machine fixtures: All installed on the milling machine table, moving with the table feed. They mainly consist of positioning devices, clamping devices, fixture bodies, connecting elements, and tool-setting elements. During milling, the cutting force is large, and the cutting is intermittent, resulting in significant vibration. Therefore, milling machine fixtures require high clamping force, as well as high rigidity and strength. 5) Bearing housing fixtures: To ensure and improve the production quality of bearing housings, in addition to using machine tools and other mechanical equipment, a large amount of process equipment is used, including bearing housing fixtures, molds, cutting tools, and related auxiliary tools. A bearing housing fixture is a production tool specifically designed to ensure the product quality of bearing housings, making the production process more convenient. Different bearing housing fixtures vary in structure, form, operating conditions, and design principles, resulting in a wide variety of types and styles, accounting for a significant proportion in both quantity and variety. This type of bearing housing fixture can accurately determine the relative position between the workpiece and the tool, meaning it can clamp the workpiece to be machined, thereby completing the motions required during the machining process. Since bearing housing fixtures play a very important role in the bearing housing production process, the drafting of bearing housing fixture design drawings is also very important.

spmaier Workpiece Fixture Structure

The mechanical gripper-type end effectors used in loading and unloading industrial robots are mostly two-finger claw types. Classified by finger motion, they can be divided into translational and rotational types. Classified by mechanical clamping method, they can be divided into external clamping and internal expanding types. Classified by mechanical structural characteristics, they can be divided into electric (electromagnetic), hydraulic, and pneumatic types, as well as their combinations. When the end effector clamps a workpiece, there should be certain force constraints and shape constraints to ensure that the clamped workpiece is fully released during movement, dwelling, and loading processes. In addition, it should ensure that the geometric deviation of the workpiece clamping posture reproduction is within the specified tolerance zone.

spmaier Workpiece Fixture Selection and Use

With the continuous development of China's industry, the use of electromagnetic chucks in industrial production is becoming increasingly widespread. The most important aspect of an electromagnetic chuck is its parameters. Among the performance parameters of an electromagnetic chuck, the most critical are the lifting capacity and its working class. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight of objects allowed to be lifted under specified working conditions, or in other words, the rated lifting capacity. Generally, the lifting capacity of a crane equipped with an electromagnetic chuck should also include the weight of the electromagnetic chuck. There are lifting screw holes on both sides of the rectangular electromagnetic chuck. During installation, T-shaped screws can be screwed in for lifting. It is 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 plane of the chuck once to ensure the parallelism of the upper plane to the bottom surface. When adsorbing a workpiece, sufficient positioning suction force can be obtained by bridging two adjacent magnetic poles, allowing grinding processing to proceed. Magnetization and demagnetization of the workpiece can be achieved through the machine tool buttons.
