Description

Technical Field

[0003]

[0001] The utility model belongs to the technical field of bearing riveting, and particularly relates to a bearing assembly riveting tooling. Background Art

[0002] In the existing bearing assembly process, traditional methods generally rely on manual operation, that is, directly placing the bearing on the product to be assembled. This step is not only inefficient but also has great potential safety hazards. Since it is difficult to ensure that the position of each placement is accurate when manually placing the bearing, during the subsequent riveting process, the bearing is easily damaged by the riveting punch directly above, resulting in bearing damage or unqualified assembly quality. In addition, when simply riveting through the riveting punch directly above, due to the single force application direction, it is often difficult to ensure the tight fit between the bearing and the product, and there are certain assembly defects. These problems not only affect the quality and performance of the product but also increase the production cost and maintenance cost.

[0003] Therefore, it is very necessary to invent a bearing assembly riveting tooling. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a bearing assembly riveting tooling, which includes a riveting seat, a positioning riveting groove, a product, a cylinder, and a loading channel. The product is positioned and restricted by the positioning riveting groove opened on the riveting seat. The output end of the cylinder fixedly installed outside the base of the riveting seat is fixed to a bearing push head, and the loading channel fixedly installed outside the base is connected to a preloading plate

[0005] Preferably, the riveting seat includes a feeding cavity and a transition plate. The feeding cavity is opened in the base. The bearing push head, the preloading plate, and the transition plate are all installed in the feeding cavity. The bearing push head is located on one side of the preloading plate, and the transition plate is fixed to the preloading plate.

[0006] Preferably, an upper punch is arranged between two parallel preloading plates, and the upper punch is fixed to a hydraulic rod arranged inside the feeding cavity.

[0007] Preferably, the loading channel is inclined. The bearing placed on the loading channel will slide towards the direction of the preloading plate. The cross-section of the loading channel is a "U" - shaped structure.

[0008] Preferably, the preloading plate is horizontally arranged. The bearing on the preloading plate is allowed to smoothly transition to the upper punch through the transition plate under the push of the bearing push head.

[0009] Preferably, the upper pressing head is located directly below the riveting area of ​​the product, and a through hole is provided on the base to allow the upper pressing head to pass through. The through hole allows the upper pressing head and the bearing thereon to pass through and rivet the bearing to the product.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This utility model realizes the automatic positioning and pushing of bearings through the design of pre-filling plates and bearing push heads, effectively avoiding the errors and safety hazards caused by manual placement.

[0019] As attached Figure 1 To the attached Figure 3 As shown:

[0020] The utility model provides a bearing assembly riveting tool, including a riveting seat 1, a positioning riveting groove 2, a product 3, a cylinder 4 and a filling channel 5. The positioning riveting groove 2 opened on the riveting seat 1 positions and restricts the product 3, the output end of the cylinder 4 fixedly mounted on the outside of the base 11 of the riveting seat 1 is fixed to the bearing push head 13, and the filling channel 5 fixedly mounted on the outside of the base 11 is connected to the pre-filling plate 14.

[0021] Furthermore, the riveting base 1 includes a loading chamber 12 and a transition plate 15. The loading chamber 12 is cleverly designed within the base 11, providing space for the installation and movement of key components such as the bearing pusher 13, pre-loading plate 14, and transition plate 15. The bearing pusher 13, located on one side of the pre-loading plate 14, is responsible for pushing the bearing from the pre-loading plate 14 to the transition plate 15. The transition plate 15 is tightly secured to the pre-loading plate 14, ensuring a smooth transition of the bearing during the pushing process.

[0022] Furthermore, to further improve assembly efficiency and quality, an upper ram 16 is installed between two parallel pre-loading plates 14. This ram 16 is connected to a hydraulic rod 17 installed within the loading chamber 12. The telescopic movement of the hydraulic rod 17 drives the upper ram 16 up and down. This design ensures that once the bearing is pushed into place, it receives even pressure from the upper ram 16, achieving a tight fit with the product.

[0023] Furthermore, the loading channel 5 is inclined, enabling the bearings placed on the loading channel 5 to slide automatically towards the preloading plate 14. The cross-section of the loading channel 5 is a "U" - shaped structure. This design not only facilitates the placement and sliding of the bearings but also effectively prevents the bearings from falling or being misaligned during the sliding process.

[0024] Furthermore, the preloading plate 14 is horizontally arranged, ensuring that the bearings can maintain a stable posture during the pushing process. When the bearings slide onto the preloading plate 14, the bearing push head 13 will continue to push the bearings under the drive of the cylinder 4, enabling them to smoothly transition to the upper pressure head 16 through the transition plate 15. This process is both fast and accurate, greatly improving the assembly efficiency.

[0025] Furthermore, finally, the upper pressure head 16 is located directly below the riveting area of the product 3. When the bearings are pushed onto the upper pressure head 16, the hydraulic rod 17 will drive the upper pressure head 16 and the bearings on it to move upward until the bearings are in close contact with the product 3. At this time, the riveting press head of the riveting lower press presses downward, applying a downward force to the product 3. At this time, with the further application of pressure by the upper pressure head 16, the bearings and the product 3 are riveted together under the up - and - down bidirectional pressure of the riveting press head and the upper pressure head 16. Among them, the through - hole penetrating through the base 11 is used for the lower pressure head 16 and the bearings on it to smoothly pass through the body, providing a basis for the upper pressure head 16 to apply force to the bearings and the product 3.

[0026] The working principle is as follows: First, place the product 3 into the positioning and riveting groove 2 of the riveting seat 1, ensuring that the product 3 is accurately positioned and restricted within the groove to prevent displacement during the assembly process. Then, place the bearings on the inclined loading channel 5. Under the action of gravity, the bearings slide automatically towards the preloading plate 14 until they slide onto the preloading plate 14. Next, the cylinder 4 starts to work, and the bearing push head 13 driven by its output end pushes the bearings on the preloading plate 14 towards the transition plate 15. The transition plate 15 is tightly fixed to the preloading plate 14, ensuring that the bearings can smoothly transition during the pushing process and avoiding damage to the bearings. Then, when the bearings are pushed to the end of the transition plate 15, they are further pushed onto the upper pressure head 16. At this time, the hydraulic rod 17 starts to work, and its telescopic movement drives the upper pressure head 16 to move upward, making the riveting area of the bearings and the product 3 align.

[0027] Subsequently, the hydraulic rod 17 continues to move upward, driving the upper pressure head 16 and the bearings on it to move upward, passing through the through - hole of the base 11 until the bearings are in close contact with the product 3. During this process, the upper pressure head 16 applies a uniform pressure to the bearings, ensuring a tight fit between the bearings and the product 3.

[0028] Finally, when the bearing and product 3 are in close contact, the riveting ram of the riveting press begins to press down, applying downward pressure to product 3. Simultaneously, the upper ram 16, driven by the hydraulic rod 17, continues to apply pressure, so that the bearing and product 3 are subjected to bidirectional pressure from the riveting ram and upper ram 16. Under the action of this bidirectional pressure, the bearing and product 3 are firmly riveted together.

[0029] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
