Description

Technical Field

[0001] The utility model belongs to the technical field of fixtures, and in particular relates to a fixture for batch cleaning end faces of shaft workpieces. Background Art

[0002] In the field of mechanical processing, after the workpiece is formed, the burrs on the surface of the workpiece need to be removed first, and then the surface of the workpiece needs to be cleaned. During the deburring and cleaning processes, the workpiece to be processed is loaded into the deburring fixture disk and the cleaning fixture disk respectively, so that the workpiece is deburred or cleaned in the fixture disk. However, due to the large structural differences between the deburring equipment and the cleaning equipment, the process of deburring or cleaning the workpiece can often only transfer the workpieces one by one to the fixture disk, and the transfer efficiency is low, which affects the production efficiency.

[0003] For example, the patent document with publication number "CN212635505U" discloses a deburring and cleaning fixture disk set for shaft parts, including a deburring fixture disk, a transition flip disk and a cleaning fixture disk, wherein: the deburring fixture disk is rectangular, and is provided with a plurality of first plug-in holes for plugging in shaft parts; the transition flip disk is rectangular, and is provided with a plurality of second plug-in holes for plugging in shaft parts corresponding to the plurality of first plug-in holes, and a positioning pin hole is respectively provided on the four corners of the transition flip disk; the cleaning fixture disk is rectangular, and is provided with a plurality of third plug-in holes for plugging in shaft parts corresponding to the second plug-in holes, and a positioning pin matching the positioning pin hole is respectively provided on the four corners of the cleaning fixture disk. This patented technology can transfer the workpiece into the fixture disk at one time, which improves the workpiece transfer efficiency to a certain extent. However, during the process of cleaning the workpiece, the bottom surface of the fixture disk blocks the end face of the workpiece, affecting the cleaning effect of the end face of the workpiece.

[0023] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0024] like Figures 1 to 5 As shown, the utility model provides a clamp for batch cleaning the end faces of shaft workpieces, including a first support rod 1, a second support rod 2 and a limit rod 3. The first support rod 1 is fixedly connected to the first support block 4, the first support block 4 is fixedly connected to the first clamp 5, the second support rod 2 is fixedly connected to the second support block 6, the second support block 6 is fixedly connected to the second clamp 7, one end of the limit rod 3 is hinged to the left and right ends of the first support rod 1, the other end of the limit rod 3 is screwed to the locking block 8, the left and right ends of the second support rod 2 are provided with limit grooves 9, and the width of the limit grooves 9 is greater than the outer diameter of the limit rod 3. When the limit rod 3 is fitted into the limit groove 9, the shaft workpiece is clamped between the first clamp 5 and the second clamp 7. By adopting the technical solution of the utility model, the first clamp and the second clamp are used to clamp the outer peripheral surface of the shaft workpiece. Shaft workpieces with different outer diameters can be clamped quickly, and multiple workpieces can be cleaned at the same time, thereby improving the workpiece transfer efficiency and production efficiency. In addition, since the first clamp and the second clamp clamp the outer peripheral surface of the shaft workpiece, there is no obstruction to the upper and lower end surfaces of the workpiece, thereby improving the cleaning efficiency of the workpiece end surface and ensuring the cleaning quality.

[0025] Specifically, tenons 10 are provided at the left and right ends of the first support block 4, and tenons 11 are provided at the left and right ends of the second support block 6.

[0026] In addition, the surface of the first clamp 5 or the second clamp 7 is also provided with a plurality of anti-skid protruding teeth 12. Preferably, the anti-skid protruding teeth 12 are in the shape of a cone as a whole, thereby increasing the friction between the surface of the workpiece and the first clamp or the second clamp to prevent the workpiece from falling.

[0027] In addition, the first clamp 5 is in a semi-cylindrical shape as a whole. The second clamp 7 is in a semi-cylindrical shape as a whole. The first support rod 1 or the second support rod 2 is made of C-shaped steel. The first support rod 1 is fixedly connected to the first support block 4 by bolts, and the second support rod 2 is fixedly connected to the second support block 6 by bolts. The first support block 4 is welded to the first clamp 5 as a whole, and the second support block 6 is welded to the second clamp 7 as a whole. The locking block 8 can be replaced by a hexagonal nut.
