Description

Technical Field

[0001] This utility model relates to the field of bearing assembly mold technology, and specifically to a bearing assembly mold tooling. Background Technology

[0002] In the bearing assembly process, the precise pressing of steel balls is a key step to ensure the bearing's rotational accuracy and service life. This step requires applying appropriate pressure to the outer ring of the bearing using a tooling fixture to create a suitable gap between the outer and inner rings, so that the steel balls can be smoothly embedded into the raceways of both rings. Ultimately, this achieves a concentric fit between the inner and outer rings and the steel balls. Existing tooling for this process often uses a "one-sided fixing, one-sided pressing" structure where a push rod holds the other end of the outer ring against it. By pressing the outer ring, the outer ring collides with the fixing block at the other end, completing the pressing of the steel balls.

[0003] However, this tooling has obvious problems. Although the fixing block is rectangular, it only abuts against one point on one end of the outer ring, forming a two-point clamp with the push rod at the extrusion end. This causes the pressure to concentrate at the two contact points of the outer ring. Point-to-point extrusion will cause indentations or wear at the contact points. Especially for bearings with high precision requirements, this local wear will directly affect the integrity of the outer ring raceway, reducing the bearing assembly accuracy and service life. Utility Model Content

[0004] The purpose of this utility model is to provide a bearing assembly mold tooling to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A bearing assembly mold tooling includes a worktable. A mounting block is disposed on the top of the worktable. A placement block is disposed on the outer side of the mounting block. A positioning block is disposed on the outer side of the placement block. A pressing assembly is disposed on the right side of the worktable, located to the right of the placement block. The pressing assembly includes a fixing block and a moving rod. The moving rod is slidably connected to the interior of the fixing block. Buffer assemblies are disposed on the right side of the mounting block and the left side of the moving rod. Each buffer assembly includes a mounting rod, an arc-shaped block, and a rubber pad. The mounting rod is fixedly installed on the outer side of the arc-shaped block, and the rubber pad is fixedly installed on the inner side of the arc-shaped block. The left mounting rod is threaded to the right side of the mounting block, and the right mounting rod is threaded to the left side of the moving rod.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the pressing assembly also includes a return spring, a connecting block, a cam, and a pressing rod. The return spring is fixedly installed on the right side of the fixed block and located on the outside of the moving rod. There are two connecting blocks, and the cam is rotatably installed inside the two connecting blocks. The rear side of the pressing rod is fixed to the front side of the cam via a rotating rod, and the right side of the moving rod is in contact with the outside of the cam.

[0009] Furthermore, a limiting plate is fixedly installed on the right side of the workbench, and two limiting grooves are opened on the top of the limiting plate. Limiting rods are fixedly installed on the right side of both the cam and the pressing rod.

[0010] Furthermore, the top of the workbench has two adjustment slots, and the mounting block is fixed to the workbench by two bolts passing through the two adjustment slots.

[0011] Furthermore, both the front and rear sides of the placement block are fixed to the mounting block by fasteners.

[0012] Furthermore, two rubber blocks are fixedly installed on the right side of the mounting block and the left side of the fixing block, and the two rubber blocks on the left and right sides respectively fit against the outer side of the corresponding side arc-shaped block.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] By increasing the contact area with the outer side of the bearing outer ring through the arc-shaped block, and in conjunction with the rubber pad, the force is dispersed when the bearing outer ring is squeezed, reducing the direct impact on the bearing outer ring and preventing damage to the bearing outer ring that may affect subsequent use. In addition, the arc-shaped block is easy to disassemble and replace, improving the convenience of subsequent maintenance of the entire device. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Reference Figures 1-4 As shown, this utility model provides a bearing assembly mold tooling, including a worktable 1, an mounting block 2 on the top of the worktable 1, a placement block 3 on the outer side of the mounting block 2, a positioning block 4 on the outer side of the placement block 3, and a pressing component 5 located to the right of the placement block 3 on the right side of the worktable 1. The pressing component 5 includes a fixing block 501 and a moving rod 502, which is slidably connected to the inside of the fixing block 501. Buffer components 6 are provided on the right side of the mounting block 2 and the left side of the moving rod 502. Each buffer component 6 includes a mounting rod 601, an arc-shaped block 602, and a rubber pad 603. The mounting rod 601 is fixedly installed on the outer side of the arc-shaped block 602, and the rubber pad 603 is fixedly installed on the inner side of the arc-shaped block 602. The left mounting rod 601 is threadedly installed on the right side of the mounting block 2, and the right mounting rod 601 is threadedly installed on the left side of the moving rod 502.

[0023] The positioning block 4 facilitates the installation of the inner bearing ring, allowing the outer bearing ring to be fitted onto the outside of the positioning block 4. A steel ball is placed between the outer and inner bearing rings. Under the action of the moving rod 502, the arc-shaped block 602 on the right side compresses the outer bearing ring, causing the outer bearing ring to move the steel ball and inner ring to the left side, where they contact the arc-shaped block 602 on the left side. This compression completes the assembly of the steel ball, and the rubber pad 603 reduces the impact of compression on the outer bearing ring.

[0024] The pressing component 5 also includes a return spring 503, a connecting block 504, a cam 505, and a pressing rod 506. The return spring 503 is fixedly installed on the right side of the fixed block 501 and is located on the outside of the moving rod 502. There are two connecting blocks 504, and the cam 505 is rotatably installed inside the two connecting blocks 504. The rear side of the pressing rod 506 is fixed to the front side of the cam 505 through a rotating rod. The right side of the moving rod 502 is in contact with the outside of the cam 505.

[0025] With this configuration, the pressing action of the pressing rod 506 drives the cam 505 to push the moving rod 502, thereby completing the squeezing operation. After the pressing rod 506 is released, the moving rod 502 is driven by the return spring 503 to push the cam 505 in the opposite direction, so that the cam 505 and the pressing rod 506 are reset.

[0026] Among them, a limiting plate 7 is fixedly installed on the right side of the workbench 1, and two limiting grooves 8 are opened on the top of the limiting plate 7. A limiting rod 9 is fixedly installed on the right side of both the cam 505 and the pressing rod 506.

[0027] With this configuration, when the cam 505 and the pressing rod 506 are reset, the cooperation between the limiting rod 9 and the two limiting slots 8 prevents the cam 505 and the pressing rod 506 from continuing to move to the right, thus limiting their position and facilitating subsequent use.

[0028] The top of the workbench 1 has two adjustment slots 10, and the mounting block 2 is fixed to the workbench 1 by two bolts passing through the two adjustment slots 10.

[0029] This configuration allows the position of mounting block 2 to be adjusted according to the size of the bearing to be assembled, thus facilitating the compression of the bearing outer ring.

[0030] The front and rear sides of the placement block 3 are fixed to the mounting block 2 by fasteners.

[0031] This setup allows for the replacement of placement block 3 after adjusting the position of mounting block 2, thereby changing the position of positioning block 4 and facilitating better adaptation to the assembly of new bearings.

[0032] Two rubber blocks 11 are fixedly installed on the right side of the mounting block 2 and the left side of the fixing block 501, and the two rubber blocks 11 on the left and right sides respectively fit against the outer side of the corresponding side arc block 602.

[0033] With this configuration, during the compression of the bearing outer ring, the arc-shaped blocks on both sides, under the action of the rubber block 11, further enhance the buffering effect and reduce the impact on the bearing outer ring.
