Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, specifically to a circular workpiece positioning assembly. Background Technology

[0002] Machining refers to the process of changing the shape, size, or properties of a workpiece using mechanical equipment. Based on the processing method, it can be divided into cutting and pressure processing. Fixtures are commonly used in machining processes; fixtures, also known as clamps, are broadly defined as any device used to quickly, conveniently, and safely install a workpiece at any stage of the manufacturing process. Examples include welding fixtures, inspection fixtures, assembly fixtures, and machine tool fixtures. Machine tool fixtures are the most common and are often simply referred to as fixtures. The machining of round workpieces often uses triangular chucks for positioning and fixing. This structure is relatively expensive and suitable for mass production, but not for small-batch production. Therefore, a round workpiece positioning component is proposed. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] The following describes some embodiments of the circular workpiece positioning assembly provided by this utility model with reference to the accompanying drawings.

[0021] Example:

[0022] Combination Figure 1-3As shown, the circular workpiece positioning assembly provided by this utility model includes a support mechanism, a fixing mechanism, and an auxiliary mechanism. The support mechanism includes a base 110, a hydraulic actuator 120 fixedly installed in the middle of the base 110, a middle plate 130 fixedly installed at the top of the hydraulic actuator 120, a hydraulic rod 140 fixedly connected to the output end of the hydraulic actuator 120, and a top plate 150 fixedly connected to the top of the hydraulic rod 140. The fixing mechanism includes a motor 210 fixedly installed on one side of the bottom of the middle plate 130, a rotating shaft 220 fixedly connected to the output end of the motor 210, a pressure plate 230 fixedly connected to the top of the rotating shaft 220, and a gear 240 fixedly sleeved in the middle of the rotating shaft 220. The toothed belt 250 is meshed with the gear 240. The top plate 150 has four corner relief grooves. The rotating shaft 220 is located in the relief grooves. There are four sets of pressure plates 230. The four sets of pressure plates 230 are evenly arranged at the four corners of the top plate 150. The inner side of the toothed belt 250 meshes with the four sets of gears 240. The four sets of gears 240 are respectively installed on the corresponding rotating shafts 220. The auxiliary mechanism includes a sleeve 310 fixedly installed on the side of the base 110 and a limiting slide rod 320 inserted into the sleeve 310 and passing through the middle plate 130 and fixedly connected to the bottom of the top plate 150. There are two limiting slide rods 320. The toothed belt 250 is movably connected to the two limiting slide rods 320.

[0023] Specifically, the toothed belt 250 synchronizes the four sets of gears 240, thereby allowing the four pressure plates 230 to be adjusted synchronously, ensuring the reliability of the structure. In addition, the limiting slide bar 320 is used to tighten the toothed belt 250 to avoid the wrap angle between the toothed belt 250 and the gears 240 being too small, which would make transmission difficult and improve the practicality of the device.

[0024] The working principle and usage process of this utility model are as follows: First, connect the power supply and the device is in standby mode. At this time, the pressure plate 230 is in the initial state. Place the circular workpiece to be positioned on the top plate 150. Then, the hydraulic rod 140 descends, and at the same time, the motor 210 drives the rotating shaft 220 to rotate. The four sets of pressure plates 230 rotate 180 degrees synchronously. After that, the hydraulic rod 140 rises, and the workpiece is clamped by the pressure plate 230 and the top plate 150 to complete the positioning and fixing.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
