Description

Technical Field

[0001] This utility model relates to the field of bearing press-fitting, and in particular to a bearing press-fitting device with a balanced support for the insertion part. Background Technology

[0002] The bearing press device for the planting section balance bracket is a device specifically used for pressing bearings onto the planting section balance bracket. Its main function is to accurately and securely install the bearings into the preset positions of the planting section balance bracket.

[0003] In existing technology, when pressing bearings into the balancing bracket of the insertion section, the operator typically first manually places the bearing at the mounting hole of the balancing bracket, visually aligns the bearing with the center axis of the hole, and then applies pressure to the outer ring of the bearing using a common press or manual pressing tools, gradually pressing the bearing into the mounting hole of the balancing bracket. During the pressing process, the equipment needs to be stopped frequently to check the pressing depth and perpendicularity of the bearing using tools such as feeler gauges. If deviations are found, the position of the balancing bracket or bearing is manually adjusted and the pressing is repeated. After pressing is completed, the stability of the installed bearing must be manually tested.

[0004] In actual operation, since the balancing supports of the insertion section have different angle specifications, the support plate angle of the support support in the existing pressing equipment is mostly fixed and cannot be adjusted according to the angle of different supports. This means that when pressing balancing supports with different angles, the operator needs to spend extra time adjusting the placement angle of the support on the support plate to adapt to the pressing requirements. This not only increases the operation steps, but also affects the accuracy of bearing pressing due to slight deviations in the placement angle of the support, and also reduces the overall efficiency of the pressing operation to a certain extent. Therefore, in response to the above problems, a bearing pressing device for the balancing supports of the insertion section was introduced. Utility Model Content

A connecting rod is fixedly connected to the top of the processing table 1. Connecting block 6 is used to hinge support frame 11. Support frame 11 is hinged to the inner wall of connecting block 6. Support frame 11 supports fixing mechanism 8. Fixing mechanism 8 is provided at the bottom of support frame 11. Fixing mechanism 8 is used to adjust and fix the angle of support plate 7. Support plate 7 is hinged to the outer wall of processing table 1. Support plate 7 is used to lower and support processing table 1 when the equipment is not in use. Fixing mechanism 8 includes sliding rod 811. The top of sliding rod 811 is hinged to the bottom of support frame 11. Sliding rod 811 can slide up and down to adjust the angle. A turntable 813 is fixedly connected to the top of support plate 7. The turntable 813 supports the elliptical block 8111 and allows it to rotate. A ball bearing 814 is rotatably connected to the top of the turntable 813. The ball bearing 814 reduces the frictional resistance of the elliptical block 8111 during rotation. An elliptical block 8111 is fixedly connected to the top of the ball bearing 814. The elliptical block 8111 is used to compress the internal compression ball 819. A connecting cylinder 812 is fixedly connected to the inner wall of support plate 7. The connecting cylinder 812 provides guidance for the sliding of the insertion rod 817. A guide rod 815 is slidably connected to the inner wall. The guide rod 815 is used to guide the sliding direction of the insertion rod 817. The insertion rod 817 is fixedly connected to the outward extension end of the guide rod 815. The insertion rod 817 is used to insert into the rectangular groove opened on the outer wall of the slide rod 811 to fix the angle. A ball sleeve 818 is fixedly connected to the inner extension end of the guide rod 815. The ball sleeve 818 is used to rotatably connect to the extrusion ball 819. The extrusion ball 819 is rotatably connected to the inner wall of the ball sleeve 818. The extrusion ball 819 is used to drive the insertion rod 817 to move when the elliptical block 8111 is extruded.

[0027] Reference Figures 1-3The outer wall of the slide rod 811 has an insertion hole, and the extension end of the insertion rod 817 is inserted into the outer wall of the slide rod 811. The outer wall of the ball sleeve 818 is fixedly connected to a spring 816, which is used to reset the insertion rod 817 when the compression is released. The extension end of the spring 816 is fixedly connected to the outer wall of the connecting cylinder 812. The inner wall of the elliptical block 8111 is rotatably connected to the outer wall of the connecting cylinder 812. The outer wall of the extrusion ball 819 contacts the inner wall of the elliptical block 8111. The outer wall of the elliptical block 8111 is slidably connected to the inner wall of the connecting cylinder 812. The extension end of the slide rod 811 is fixedly connected to a handle, which is used to facilitate the user to operate the slide rod 811. The inner wall of the support plate 7 is threadedly connected to a bolt B12. The extension end of the bolt B12 abuts against the outer wall of the elliptical block 8111. The bolt B12 is used to limit the abutment of the elliptical block 8111 to ensure its stability.

[0028] Reference Figures 3-5 The outer wall of the processing table 1 is threaded with bolt A9. The extended end of bolt A9 is threaded to the outer wall of the support plate 7. Bolt A9 is used to fix the support plate 7 after angle adjustment. The outer wall of the mounting column 4 is fitted with a locking buckle 13. There are two sets of insertion rods 817. The two sets of insertion rods 817 are symmetrically arranged at both ends of the inner wall of the connecting cylinder 812. The two sets of insertion rods 817 can be inserted into the rectangular groove on the outer wall of the slide rod 811 at the same time to improve the stability of the fixation. The bottom of the large air cylinder 2 is fixedly connected with a small air cylinder 14.

[0029] Working principle: A large air cylinder 2 is installed below the processing table 1. When pressing the bearing onto the balance mounting bracket 5, the first bearing is first fitted onto the mounting post 4, then the balance mounting bracket 5 is fitted onto the mounting post 4. Next, the second bearing is fitted onto the mounting post 4. The locking buckle 13 is then fastened to the top of the groove in the mounting post 4. The large air cylinder 2 then pulls the mounting post 4 downwards, thereby pulling the second bearing at the top of the bracket and pressing it against the inner wall of the balance mounting bracket 5. Subsequently, the small air cylinder 14 lifts the large air cylinder 2 upwards, causing the first bearing to be pressed against the bottom of the bracket, thus completing the pressing of the balance mounting bracket 5. The bearing is press-fitted, and the angle of the balance mounting bracket 5 can be adjusted according to different needs. When adjustment is required, the sliding rod 811 hinged at the bottom of the adjustment bracket is quickly slid up and down. After the angle position is determined, the elliptical block 8111 is manually rotated, and the elliptical block 8111 squeezes the internal extrusion ball 819, thereby driving the insertion rod 817 at one end of the extrusion ball 819 to insert into the rectangular groove opened on the outer wall of the sliding rod 811, thereby quickly completing the fixation. Then, the elliptical block 8111 is abutted and limited by the bolt B12 to ensure the stability of the elliptical block 8111.

[0030] When the bearing press-fitting equipment is not in use, the support plate 7 and support frame 11 are lowered. The support plate 7 is locked by bolt A9 after the fixed angle adjustment. When the support plate 7 is lowered vertically, bolt B12 is inserted in the opposite direction so that bolt B12 abuts against the support frame 11 at the bottom of the processing table 1, which limits the support plate 7 after it is lowered vertically, thereby preventing the support plate 7 from swaying.

[0031] 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.
