During the processing of the oil distribution plate, in order to ensure the processing accuracy, improve the processing efficiency and ensure the safety of the operator, a positioning fixture is required.

[0003] After searching, the Chinese patent announcement number: CN213827949U discloses a processing and fixing device for an oil distribution plate, which positions the oil distribution plate through a positioning column. Due to the design of the groove on the oil distribution plate and the protrusion on the positioning column, the positioning is convenient and accurate. The internal thread of the hollow column on the oil distribution plate corresponds to the mounting hole on the base, and is fastened by bolts. The fastening effect is good, and it is not easy to rotate or displace during processing, thereby improving the processing efficiency and product quality.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 2 The utility model provides an embodiment: a processing and positioning fixture for opening an oil channel for an oil distribution plate, comprising a bottom plate 1, a support frame 2 is fixedly connected to the top of the bottom plate 1, a slot is provided on the support frame 2, a moving block 6 can slide along the inner wall of the inner wall support frame 2, the bottom end of the support frame 2 is elastically connected to a connecting plate 4 through a return spring 3, the connecting plate 4 mainly supports and connects the hinge rod 5, the top of the connecting plate 4 is hinged to a moving block 6 through the hinge rod 5, and a clamping Mechanism, the top of the support frame 2 is fixedly connected with a contact plate 9, and the contact plate 9 can cooperate with the clamping plate 8 to fix the oil distribution plate, so that the subsequent processing of the oil distribution plate will not cause the possibility of movement, the top of the bottom plate 1 is rotatably connected with a rotating rod 10, and a plurality of discs are distributed on the rotating rod 10, and the gaps between the discs are the same size as the block 11, so that the gaps between the discs can block the vertical movement of the block 11, and there are openings on the discs, so that the block 11 can pass through the disc, and the inner side wall of the connecting plate 4 is fixedly connected with the block 11.

[0031] Reference Figure 1 and Figure 3The inner wall of the moving block 6 is movably connected with the fixed block 7, and the right end of the fixed block 7 is rotatably connected with the threaded rod 12. The threaded rod 12 can move the fixed block 7 laterally in the moving block 6, so that the position of the splint 8 changes. The inner wall of the moving block 6 is fixedly connected with a guide tube 13. The guide tube 13 can allow the fixed block 7 to move laterally on the inner wall of the moving block 6, and the moving trajectory will not be offset. The threaded rod 12 penetrates and is threadedly connected to the inner wall of the moving block 6. At the rotation point of the moving block 6 and the threaded rod 12, the moving block 6 is provided with a pattern matching the threaded rod 12, and the fixed block 7 is slidably connected to the outer wall of the guide tube 13.

[0032] Reference Figure 1-Figure 3 The clamping mechanism includes a clamping plate 8, which is fixedly connected to the top of the fixed block 7. The clamping plate 8 contacts the top of the support frame 2. The contact surfaces of the clamping plate 8, the contact plate 9 and the oil distribution plate are all made of soft plastic materials, which can increase the friction between the oil distribution plate and the clamping plate 8 and the contact plate 9, and reduce the possibility of movement of the oil distribution plate. The bottom end of the support frame 2 is fixedly connected to one end of the return spring 3. When the connecting plate 4 moves downward, the return spring 3 will be stretched. When resetting, the elastic force of the return spring 3 is used to return the connecting plate 4. The other end of the return spring 3 is fixedly connected to the top of the connecting plate 4. The connecting plate 4 is movably connected to the outer wall of the rotating rod 10, and the clamping block 11 is clamped with the inner side wall of the rotating rod 10. Here, the inner side wall represents the contact surface between the disks and the clamping block 11. The top end of the connecting plate 4 is hinged to one end of the hinged rod 5. Since the length of the hinged rod 5 is certain, when the connecting plate 4 moves downward with one end of the hinged rod 5, the hinged rod 5 at the other end will bring the splint 8 closer to the contact plate 9. On the contrary, when the connecting plate 4 moves upward with one end of the hinged rod 5, the hinged rod 5 at the other end will bring the splint 8 away from the contact plate 9. The other end of the hinged rod 5 is hinged to the bottom end of the moving block 6.

[0033] Working principle: First, when the oil distribution plate needs to be fixed, just move the oil distribution plate close to and in contact with the contact plate 9, then press the connecting plate 4 downward to move the hinged rod 5 and the block 11 downward and stretch the reset spring 3, then the hinged rod 5 will bring the moving block 6, the fixed block 7 and the clamping plate 8 to the contact plate 9 and fix the oil distribution plate to ensure that there will be no movement during the processing. When limiting is required, the inner side wall of the rotating rod 10 is rotated to engage with the outer wall of the block 11, and the reverse elastic force of the reset spring 3 is used to keep the block 11 engaged with the inner side wall of the rotating rod 10.

[0034] When it is necessary to observe the processing status of a single oil distribution plate or take it out, it is only necessary to rotate the threaded rod 12 to allow the threaded rod 12 to move the fixing block 7 and the clamping plate 8 to the right, so that the clamping plate 8 is not in contact with the oil distribution plate, and then take the oil distribution plate out from between the contact plate 9 and the clamping plate 8. When it is necessary to continue processing and fixing a single oil distribution plate, rotate the threaded rod 12 in the opposite direction to allow the fixing block 7 and the clamping plate 8 to move to the left, so that the clamping plate 8 and the contact plate 9 cooperate to complete the fixation of the oil distribution plate.

[0035] When multiple sets of oil distribution plates need to be released, it is only necessary to rotate the rotating rod 10 to make the block 11 and the opening of the rotating rod 10 overlap, and then use the reverse elastic force of the reset spring 3 to slowly reset the connecting plate 4, the hinge rod 5 and the moving block 6, so that the moving block 6 can be slowly moved away from the oil distribution plate to release the fixation.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
