Description
Technical Field

[0002] In the field of mechanical manufacturing, circular parts are often processed. In order to improve the processing accuracy, a positioning tool is needed to fix the circular parts. After searching, the Chinese patent authorization number CN217966917U discloses a circular part processing positioning tool. The device solves the problem that the circular part processing positioning tool cannot adjust the processing angle and has high production cost through a positioning structure and a frame. However, the device only fixes the two ends of the circular part through a positioning clamp. Although the surface of the positioning clamp of the device is provided with an arc-shaped groove for fitting the circular part, the shape of the arc-shaped groove is fixed and it cannot be applied to circular parts of different diameters, which will greatly reduce the clamping stability. The two sides of the circular part that are not clamped are prone to shaking up and down during the processing, and the positioning tool cannot position multiple circular parts of different sizes at the same time. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a positioning tool for the production of circular parts, which solves the problem raised in the background technology that although the surface of the positioning clamp of the existing positioning tool is provided with an arc-shaped groove for fitting the circular parts, due to the fixed shape of the arc-shaped groove, it cannot be applied to circular parts of different diameters, which will lead to a significant reduction in the clamping stability, the two sides of the circular parts that are not clamped are prone to up and down shaking during the processing, and the existing positioning tool cannot simultaneously position multiple circular parts of different sizes.
[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions: a positioning tool for circular parts production, including a device body, a positioning plate, a lifting block, a clamping block and an adjusting bolt, the four ends of the device body are provided with positioning bolts, the top of one end of the device body is connected to the positioning plate through a rotating shaft, the part body is placed on the top of the positioning plate, a positioning block is provided on the outside of the part body, the top of the positioning block is threadedly connected to the adjusting bolt, the bottom of the adjusting bolt is rotatably connected to the lifting block, a clamping block is provided on one side of the bottom of the lifting block, the bottom of the clamping block is slidably connected to the positioning block, and two pins are welded to the bottom of the positioning block.
[0005] Preferably, circular holes are evenly distributed on the surface of the positioning plate, and the circular holes on the surface of the positioning plate are arranged at equal intervals, and pins are inserted into the circular holes on the surface of the positioning plate. Through the holes on the surface of the positioning plate, the pins can select a suitable insertion position according to the size of the parts, so that the clamping block can clamp and position parts of different sizes.
[0006] Preferably, one side of the lifting block and the clamping block are both sloped structures, and the lifting block and the clamping block slope are in sliding contact, which is conducive to enabling the lifting block to push the clamping block to move when it moves downward, thereby clamping the part.
[0007] Preferably, the bottom of the clamping block is provided with a convex structure, and the convex structure at the bottom of the clamping block is T-shaped, and the convex structure at the bottom of the clamping block is consistent with the shape of the groove on the surface of the positioning block, which is conducive to the bottom of the clamping block being able to slide through the groove on the surface of the positioning block.
[0008] Preferably, a hexagonal groove is provided on the top of the adjusting bolt, and the shape of the hexagonal groove on the top of the adjusting bolt matches the shape of the bottom of the adjusting rod. A rotating rod is welded on the top of the adjusting rod, which is beneficial for rotating multiple adjusting bolts with only one adjusting rod, and they can be easily removed after rotation.
[0009] Preferably, adjustment holes are opened in a straight line and at equal intervals on both sides of the device body, and the adjustment holes are threadedly connected to the fastening bolts. The fastening bolts are inserted into the hole grooves at one end of the support rod, and the other end of the support rod is rotatably connected to the side of the positioning plate.

[0010] The utility model provides a positioning tool for circular parts production, which has the following beneficial effects:
[0011] (1) A positioning tool for producing circular parts. When the device is used, the part is placed on a positioning plate, and then positioning blocks are placed on the four directions of the outside of the part. The pin at the bottom of the positioning block is inserted into the hole groove on the surface of the positioning plate, and the bottom of the adjusting rod is inserted into the hexagonal groove on the top of the adjusting bolt. The adjusting bolt can be moved downward by rotating the rotating rod. When the adjusting bolt moves downward, it will drive the lifting block to move downward, and when the lifting block moves downward, the clamping block can slide through the slope structure on one side, so that one end of the clamping block can be against the side of the circular part, and the circular part is clamped and positioned from four directions, which is beneficial to prevent the circular part from shaking during processing. At the same time, through the cooperation of the hole groove on the surface of the positioning plate and multiple clamping assemblies, multiple circular parts of different diameters can be positioned at the same time.
[0012] (2) This positioning tool for producing circular parts can remove the fastening bolts to allow the positioning plate to rotate through the rotating shaft, thereby allowing the angle of the positioning plate to be adjusted, so that the parts can be processed at a suitable processing angle. The fastening bolts are then inserted back into one end of the support rod and threadedly connected to the adjustment hole on the side of the device body, so that the angle of the positioning plate can be fixed under the support of the support rod.
[0013] This solves the problem that the surface of the positioning clamp of the existing positioning tool is provided with an arc-shaped groove for fitting circular parts, but due to the fixed shape of the arc-shaped groove, it cannot be applied to circular parts of different diameters, which will greatly reduce the clamping stability, and the two sides of the circular parts that are not clamped are prone to up and down shaking during the processing, and the existing positioning tool cannot position multiple circular parts of different sizes at the same time.
