The first clamping part is detachably and fixedly connected to the base and is clamped with the sleeve, and the second clamping part is arranged on one side of the base opposite to the first clamping part and can be inserted into the sleeve. The clamping mechanism for sleeve processing in this application has the effects of restricting the circumferential rotation, horizontal movement and vertical jump of the sleeve, reducing the phenomenon of shaft jumping during the processing of the sleeve, and thus improving the processing accuracy of the sleeve.

[0004] This device achieves the separate clamping of each sleeve by setting the first clamping part and the second clamping part. Long-term operation of the device to separately release and fix the limit of each sleeve increases the operation time of the staff and reduces the work efficiency of the staff. Therefore, a positioning and clamping mechanism for sleeve processing is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a positioning and clamping mechanism for sleeve processing, aiming to improve the problem that the separate release and fixed limit of the sleeve in the prior art delays the processing efficiency.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 3 For an embodiment provided by the present utility model: a positioning and clamping mechanism for sleeve processing includes a bottom plate 1, which provides a stable support effect for the overall device. A clamping mechanism is provided on the outer wall of the bottom plate 1, which can provide a stable fixing effect for the sleeve 10. The clamping mechanism includes a short rod 8. The bottom of the short rod 8 is hinged with a connecting rod 9. There are two groups of connecting rods 9 on the left and right, so that the short rod 8 provides a stable fixing effect for the connecting rod 9. The bottom of the connecting rod 9 is hinged with a fixed block 2. The two groups of connecting rods 9 on the left and right are respectively hinged with two fixed blocks 2, so that the up and down movement of the connecting rod 9 can push the two fixed blocks 2 to move in opposite directions left and right. A plastic block 3 is fixedly connected to the outer wall of the fixed block 2, so that the fixed block 2 provides a stable fixing effect for the plastic block 3. The outer wall of the plastic block 3 contacts the sleeve 10. When the fixed block 2 pushes the plastic block 3 to clamp the sleeve 10, the contact area between the plastic block 3 and the sleeve 10 is increased, and the friction force is increased, so that the sleeve 10 is clamped more stably. A convex block 14 is fixedly connected to the bottom of the fixed block 2, so that the fixed block 2 provides a stable fixing effect for the convex block 14. A groove is opened on the outer wall of the bottom plate 1, and the outer wall of the convex block 14 is slidably connected to the outer wall of the groove, so that the convex block 14 can drive the fixed block 2 to slide stably horizontally along the inner wall of the groove, so that the fixed block 2 does not move randomly.

[0031] Refer toFigure 2 - Figure 3 At the top of the short rod 8, a disc 7 is fixedly connected, so that the short rod 8 provides a stable fixing effect for the disc 7. The inner wall of the disc 7 is elastically connected with a round rod 11 through a spring 12. One end of the spring 12 is fixedly connected to the inner wall of the disc 7, and one end of the spring 12 is fixedly connected to the outer wall of the round rod 11, so that the spring 12 cooperates with the inner wall of the disc 7 to provide a reaction force for the round rod 11. The outer wall of the round rod 11 is slidably connected to the inner wall of the disc 7, so that the inner wall of the disc 7 provides a stable sliding effect for the round rod 11. The outer wall of the disc 7 is rotatably connected with a threaded rod 6, so that the outer wall of the disc 7 provides a stable rotating effect for the threaded rod 6.

[0032] Refer to Figure 2 - Figure 3 As shown in Fig. - Fig., a circular groove is provided in the inner wall of the threaded rod 6, and the outer wall of the round rod 11 is inserted into the inner wall of the circular groove, so that when it is necessary to rotate the threaded rod 6 alone, the round rod 11 is pulled out of the circular groove. When it is not necessary to rotate the threaded rod 6 alone, the round rod 11 is pushed back into the circular groove by the reaction force generated by the spring 12 cooperating with the inner wall of the disc 7. The outer wall of the threaded rod 6 is threadedly connected to the inner wall of the fixed rod 5, so that the threaded rod 6 can rotate along the thread of the fixed rod 5. A cross bar 13 is fixedly connected to the inner wall of the threaded rod 6, so that the threaded rod 6 can be rotated by twisting the cross bar 13. A hydraulic rod 4 is fixedly connected to the outer wall of the fixed rod 5, so that the release and fixation of the clamping mechanism are controlled by controlling the up and down movement of the hydraulic rod 4. The bottom of the hydraulic rod 4 is fixedly connected to the top of the bottom plate 1, so that the bottom plate 1 provides a stable supporting effect for the hydraulic rod 4. The outer wall of the bottom plate 1 is in contact with the outer wall of the sleeve 10, so that the bottom plate 1 provides a stable supporting effect for the sleeve 10.

[0033] Working principle: When the staff processes the sleeve 10, the sleeve 10 is moved onto the bottom plate 1, and each sleeve 10 is displaced between a group of fixed blocks 2. If all the sleeves 10 have the same size at this time, the hydraulic rod 4 is controlled to rise. Then, the fixed rod 5 fixedly connected to the top of the hydraulic rod 4 moves upward. At this time, the threaded rod 6 threadedly connected to the inner wall of the fixed rod 5 is inserted by the round rod 11 slidably connected to the disc 7, so that the threaded rod 6 and the fixed rod 5 move upward together. The short rod 8 fixedly connected to the bottom of the disc 7 also moves upward. At this time, the connecting rod 9 hinged to the short rod 8 moves upward, pulling a group of fixed blocks 2 hinged to the bottom, so that the convex block 14 fixedly connected to the fixed block 2 moves horizontally along the groove of the bottom plate 1 towards the sleeve 10. The plastic block 3 fixedly connected to the fixed block 2 clamps the sleeve 10, and the contact area between the plastic block 3 and the sleeve 10 is increased during the movement, increasing the friction force until the sleeve 10 is stably clamped, so that the staff can process the sleeve 10.

[0034] If there are differences in the sizes of the sleeves 10, after the large-sized sleeve 10 is clamped, the small-sized sleeve 10 needs to be processed separately. Then, the round rod 11 slidingly connected to the inner wall of the disc 7 is pulled out so that the threaded rod 6 can rotate independently. The cross bar 13 at the top of the threaded rod 6 is twisted to move the threaded rod 6 upward until the fixing block 2 and the plastic block 3 clamp the sleeve 10. Then, the round rod 11 is released so that the round rod 11 is inserted back into the round groove of the threaded rod 6 under the reaction force generated by the cooperation of the spring 12 and the inner wall of the disc 7.

[0035] After the overall sleeve 10 is processed, the hydraulic rod 4 is operated to move downward, causing the fixed rod 5 fixedly connected to the top of the hydraulic rod 4 to move downward. At this time, the threaded rod 6 threadedly connected to the inner wall of the fixed rod 5 is inserted by the round rod 11 slidingly connected to the disc 7, causing the threaded rod 6 and the fixed rod 5 to move downward together. The short rod 8 fixedly connected to the bottom of the disc 7 also moves downward. At this time, the connecting rod 9 hinged to the short rod 8 moves downward, pulling a set of fixing blocks 2 hinged to the bottom thereof to move horizontally in the opposite direction of the sleeve 10. The plastic block 3 fixedly connected to the fixing block 2 relaxes the sleeve 10, and the staff can take out the sleeve 10 for the next operation.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
