German ronar workpiece fixtures ronar model ronar price

ronar workpiece fixtures are devices that hold objects to manipulate them. They can grip and release objects while performing certain actions. Motion devices often mimic human movements; in the case of grippers, they mimic finger movements. The "fingers" themselves do not belong to the gripper; they are merely specialized custom tools for holding objects, called "jaws." Two main gripping actions: External gripping: This is the most common method for holding objects. It is the simplest and requires the shortest stroke length. When the gripper jaws close, the clamping force applied by the gripper will hold the object. Internal gripping: In some applications, due to the geometry of the object or the need to access the exterior of the object, it is necessary to grip the object from the center. In this case, the gripper will hold the object through expansion force.

ronar 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) CMM fixtures: Used on coordinate measuring machines, utilizing their modular support and reference devices to achieve flexible fixation of the measured workpiece. This device can be automatically programmed to support the workpiece and establish an infinite number of workpiece configuration reference points. Advanced dedicated software can directly generate the workpiece clamping program within seconds using 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 equipment. They mainly appear in modern industrial production in conjunction with robots, with common applications in automated unmanned factories for machine tool loading/unloading, workpiece palletizing/depalletizing, welding, grinding, etc. 4) Milling machine fixtures: All installed on the milling machine table, moving with the table feed motion. 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, and high stiffness 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, i.e., 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.

ronar workpiece fixture structure

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

ronar workpiece 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 screw 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 adsorbing 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 precision. 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.
