Technical Field
[0001] This utility model relates to the field of press-fit fixture technology, and in particular to a press-fit fixture for box cover bearings. Background Technology
[0002] Press-fit fixtures are specialized tooling equipment used to precisely and stably press parts (such as bearings, bushings, bushings, pins, etc.) into the preset mating positions of another workpiece (such as housings, shells, flanges, etc.) by applying controllable pressure. They are widely used in machinery manufacturing, automotive parts, home appliance assembly and other fields.
[0003] The existing technology has the following drawbacks: some existing box cover bearing pressing fixtures are inconvenient to disassemble and remove during use.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3 This utility model provides an embodiment of a box cover bearing pressing fixture, including a worktable 1, a lower pressure plate 2 on the top of the worktable 1, which presses the box cover bearing; a telescopic rod 3 is fixedly connected to the bottom of the worktable 1, and a base 4 is fixedly connected to the top of the telescopic rod 3; a placement groove is opened inside the worktable 1, and the base 4 is slidably connected in the placement groove; a processing frame 6 is provided on the top of the base 4, and a connecting component 5 is provided on the bottom of the processing frame 6, which limits the processing of the box cover bearing;
[0033] Furthermore, a pushing mechanism 7 is provided inside the worktable 1, and a positioning frame 8 is fixedly connected to the side wall of the processing frame 6. A positioning groove adapted to the size of the positioning frame 8 is opened inside the worktable 1. The positioning groove is used to place and connect the positioning frame 8. A positioning block 9 is slidably connected inside the positioning frame 8. A positioning hole is opened on the inner side wall of the positioning groove. The positioning block 9 passes through the positioning frame 8 and is inserted into the positioning hole. Through the positioning hole and the positioning block 9, the positioning frame 8 is stably inserted into the inside of the worktable 1.
[0034] Furthermore, a push rod 11 is provided on the top of the positioning block 9. The push rod 11 passes through and is slidably connected to the top of the positioning frame 8. Pushing the push rod 11 causes the positioning block 9 to slide inside the positioning frame 8. A positioning spring 10 is fixedly connected to the side wall of the positioning block 9. There are two positioning blocks 9. The opposite surfaces of the two positioning blocks 9 are connected to the two ends of the positioning spring 10. Pushing the positioning block 9 compresses the positioning spring 10, causing the positioning spring 10 to deform. When resetting, the rebound of the positioning spring 10 causes the positioning block 9 to slide and reset.
[0035] Reference Figures 2-4 The pushing mechanism 7 includes a push plate 71, which is rotatably connected to the inner wall of the push plate 71. The top of the push plate 71 contacts the bottom of the base 4. The push plate 71's rebound causes the base 4 to slide inside the placement groove. The bottom of the push plate 71 is elastically connected to the inner wall of the worktable 1 through a return spring 72. When the push plate 71 is pushed, it squeezes the return spring 72, causing the return spring 72 to deform. During reset, the return spring 72's rebound causes the push plate 71 to slide and reset.
[0036] Reference Figures 3-5 The connecting component 5 includes a connecting rod 51, the top of which is fixedly connected to the bottom of the processing frame 6. The base 4 has a connecting groove inside that matches the size of the connecting rod 51. The connecting groove ensures a stable connection between the connecting rod 51 and the base 4. A connecting block 52 is fixedly connected to the side wall of the connecting rod 51. A limiting groove is provided on the inner side wall of the connecting groove. The connecting block 52 is slidably connected in the limiting groove. The limiting groove allows the connecting block 52 to rotate inside the base 4, thereby improving the stable connection between the connecting rod 51 and the base 4.
[0037] Working principle: When in use, pushing the push rod 11 drives the positioning block 9, which in turn squeezes the positioning spring 10 and drives the positioning block 9 into the interior of the positioning frame 8. At the same time, pressing the processing frame 6 drives the base 4 to squeeze the push plate 71 and enter the interior of the worktable 1. Releasing the push rod 11 causes the positioning spring 10 to rebound, causing the positioning block 9 to slide out from the interior of the positioning frame 8 and insert into the interior of the worktable 1, improving the stability of the processing frame 6 during the processing process. Then, the box cover bearing that needs to be pressed in is placed inside the processing frame 6. The lower pressure plate 2 is used to press down the items inside the processing frame 6 to process the objects.
[0038] After the items inside the processing frame 6 are processed, push the push rod 11 to drive the positioning block 9 to squeeze the positioning spring 10 and slide it into the inside of the positioning frame 8. Then, the return spring 72 causes the push plate 71 to return and reset, and then drives the base 4 to slide inside the worktable 1, so that the processing frame 6 slides out from inside the worktable 1, thus satisfying the effect of disassembling and picking up the processed items.
[0039] When it is necessary to change the processing frame 6 to process items of different sizes, rotating the processing frame 6 will drive the connecting rod 51 to rotate the connecting block 52, and then pull the connecting block 52 out from the inside of the base 4. Then the processing frame 6 will be pulled out from the inside of the base 4 to achieve the effect of processing box cover bearings of different sizes.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
