Description

Technical Field

[0001] This utility model relates to the field of mirror bracket bearing press-fitting technology, specifically to a mirror bracket bearing press-fitting device. Background Technology

[0002] A mirror is an optical element that works based on the law of reflection; mirrors are typically mounted on a mirror mount. (See reference...) Figure 1 As shown, the reflector bracket has mounting shafts at both ends. The pre-assembled bearing assembly needs to be press-fitted onto the mounting shaft. The bearing assembly includes a bearing and a bearing housing.

[0003] In existing technologies, bearing assemblies are typically assembled manually or through mechanical pressing. Manual assembly usually involves first fitting the bearing assembly onto the end of the mounting shaft, then attaching a sleeve to the shaft and making contact with the bearing assembly. The bearing assembly is then gradually pressed onto the shaft by hammering the sleeve. This pressing process is inefficient, and the lack of fixation of the reflector bracket during pressing makes it prone to movement and affecting the final result. Mechanical pressing typically uses a series of moving mechanisms to control the bearing assembly as it gradually approaches the mounting shaft until pressing is complete. However, existing mechanical structures often combine the pressing mechanism with the mechanism for adjusting the bearing assembly's position relative to the mounting shaft, resulting in low adjustment precision. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide a reflector bracket bearing press-fitting device, comprising:

[0005] Support frame, the support frame being used to hold the reflector bracket;

[0006] A press-fitting assembly includes a first telescopic cylinder, an adjustment module disposed at the output end of the first telescopic cylinder, and a press-fitting block disposed at the output end of the adjustment module. The press-fitting block is used to place the bearing assembly and corresponds to the mounting shaft. The adjustment module is used to drive the press-fitting block to move to be opposite to the mounting shaft. The first telescopic cylinder is used to control the press-fitting block to press the bearing assembly onto the mounting shaft.

[0007] A clamping assembly is used to cooperate with the support frame to clamp the reflector bracket.

[0008] Furthermore, the adjustment module includes a first moving cylinder and a second moving cylinder. The first moving cylinder is connected to the output end of the first telescopic cylinder, the second moving cylinder is connected to the output end of the first moving cylinder, and the output end of the second moving cylinder is connected to the pressing block.

[0009] Furthermore, the clamping assembly includes several clamping members, each clamping member having a clamping block, the clamping block being adapted to the reflector bracket, and the clamping member being rotatable and movable relative to the support frame.

[0010] Furthermore, the press block is provided with a positioning slot that is compatible with the bearing assembly.

[0011] Furthermore, the support frame is provided with a plurality of support blocks, and the plurality of support blocks are all in contact with the reflector bracket.

[0012] Furthermore, the support frame is also provided with a positioning rod, which is compatible with the mounting holes on the reflector bracket.

[0013] Furthermore, the support frame is provided with a limiting plate, which abuts against the pressing block.

[0014] Furthermore, the clamping block is provided with a support plate, and the limiting plate is provided with a positioning plate adapted to the support plate. The positioning plate and the limiting plate cooperate to form a cavity. The width of the cavity is adapted to the support plate. When the support plate enters the cavity, the bearing assembly and the mounting shaft correspond.

[0015] The beneficial effects of this utility model are as follows: It provides a bearing pressing device for a reflector bracket, including a support frame, a pressing assembly, and a clamping assembly. The pressing assembly includes a first telescopic cylinder, an adjusting module, and a pressing block. During the pressing process, the adjusting module controls the clamping block to move the bearing assembly. As the clamping block moves, it applies force to the bearing assembly, thereby pressing the bearing assembly onto the mounting shaft. Compared with the prior art, which uses a sleeve that contacts the bearing assembly with a manual hammer to press the bearing assembly, this method is more efficient. Simultaneously, the clamping assembly and the support frame work together to press the reflector bracket, making it less prone to shaking during the pressing process, further improving pressing efficiency. Before controlling the pressing block to press, the adjusting module near the mounting shaft adjusts the position of the pressing block to align it with the mounting shaft. Then, the first telescopic cylinder controls the pressing block to move closer to the mounting shaft to complete the pressing. Compared to existing technologies that combine the moving mechanism for controlling the pressing and the moving mechanism for adjusting the position of the pressing block relative to the mounting shaft into a single drive, this method achieves higher adjustment precision for pressing the pressing block.

Detailed Implementation

[0024] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Please refer to Figure 2-6 A reflector bracket bearing press-fitting device 100 is provided, including a support frame 10 for placing a reflector bracket 200, a press-fitting assembly 20 and a clamping assembly 30, and a frame 40 for supporting the various components.

[0026] With the height direction of the frame 40 in the figure as the vertical direction, and the top surface of the frame 40 as the horizontal plane.

[0027] Please refer to Figure 1 and Figure 2The reflector bracket 200 has an overall arc-shaped plate structure. At each end of its length, there is a mounting shaft 201 and a mounting hole 202. The support frame 10 has several support blocks 11 and positioning rods 12, with the support blocks 11 fitting snugly against the reflector bracket 200. The positioning rods 12 are matched with the mounting holes 202 on the reflector bracket 200.

[0028] More specifically, there are three support blocks 11, each corresponding to one of the three protrusions 204, and the top surfaces of the three support blocks 11 are set to fit against the bottom surface of the reflector bracket 200. The positioning rods 12 are arranged in pairs about the center of the support frame 10. When the reflector bracket 200 is placed, the positioning rods 12 pass through the mounting holes 202 to limit the position of the reflector bracket 200.

[0029] The bearing assembly 300 includes a bearing 301 and a bearing housing 302. The bearing 301 and the bearing housing 302 are pre-assembled. The bearing housing 302 includes a main body 3021 coaxially arranged with the bearing 301 and three mounting parts 3022 disposed on the side wall of the main body 3021.

[0030] The press-fit assembly 20 includes a first telescopic cylinder 22, an adjustment module with the output end of the first telescopic cylinder 22, and a press-fit block 21 with the output end of the adjustment module. The press-fit block 21 is used to place the bearing assembly 300. The press-fit block 21 corresponds to the mounting shaft 201. The press-fit block 21 has a positioning groove 211 adapted to the bearing assembly 300. The shape of the positioning groove 211 is the same as the shape of the bearing housing 302. The positioning groove 211 limits the mounting part 3022 of the bearing housing 302, so that the entire bearing assembly 300 is not easily axially displaced relative to the press-fit block 21. The adjustment module is used to drive the press-fit block 21 to move and press the bearing assembly 300 onto the mounting shaft 201.

[0031] Furthermore, the adjustment module includes a first moving cylinder 23 and a second moving cylinder 24. The output ends of the first moving cylinder 23 and the first telescopic cylinder 22 are fixedly connected. The output end of the second moving cylinder 24 is fixedly connected to the output end of the first moving cylinder 23. The output end of the second moving cylinder 24 is fixedly connected to the pressing block 21. The output end of the second moving cylinder 24 is provided with a connecting plate 241 for supporting the pressing block 21. The output end of the second moving cylinder 24 is fixedly connected to the pressing block 21 through the connecting plate 241. In this embodiment, both the first moving cylinder 23 and the second moving cylinder 24 are rodless cylinders.

[0032] Specifically, in this embodiment, two sets of pressing components 20 are provided, each set being located at one end of the support frame 10 along its length, corresponding to the two mounting shafts 201 on the reflector bracket 200. A first telescopic cylinder 22 is positioned along the length of the frame 40. The first telescopic cylinder 22 controls a first moving cylinder 23 to slide along the length of the frame 40. The first moving cylinder 23 controls a second moving cylinder 24 to slide along the height of the frame 40. The second moving cylinder 24 controls the pressing block 21 to slide along the width of the frame 40. The first moving cylinder 23 and the second moving cylinder 24 cooperate to control the pressing block 21 to first move to a position directly opposite the mounting shaft 201, and then the first telescopic cylinder 22 controls the pressing block 21 to move towards the mounting shaft 201 until pressing is completed.

[0033] In this invention, a first moving cylinder 23 and a second moving cylinder 24 with mutually perpendicular moving directions are set at the output end of the first telescopic cylinder 22. Before pressing the pressing block 21, the position of the pressing block 21 is adjusted by the first moving cylinder 23 and the second moving cylinder 24 near the mounting shaft 201, and then the first telescopic cylinder 22 controls the pressing block 21 to move closer to the mounting shaft 201. Compared with the prior art, which combines the moving mechanism for controlling the pressing block 21 to move closer to the mounting shaft 201 and the moving mechanism for adjusting the position of the pressing block 21 relative to the mounting shaft 201 into a single drive, the adjustment accuracy of pressing the pressing block 21 is higher.

[0034] The clamping assembly 30 is used to cooperate with the support frame 10 to clamp the reflector bracket 200. The clamping assembly 30 includes several clamping members 31. The output end of the clamping member 31 is provided with a clamping block 311. The clamping block 311 is adapted to the reflector bracket 200, and the clamping member 31 can rotate and rise relative to the support frame 10. In this embodiment, there are five clamping members 31, which are respectively arranged on both sides of the reflector bracket 200 in the width direction and can conform to the shape of the reflector bracket 200 for clamping. After the clamping is completed, it can be raised and lowered to release the clamping of the reflector bracket 200 and then rotated away from the reflector bracket 200.

[0035] Furthermore, the clamping component 31 can be a rotary pressing cylinder, a combination of a lead screw transmission mechanism and a rotary cylinder, or a combination of a lifting cylinder and a rotary cylinder. In this embodiment, the clamping component 31 shown in the accompanying drawings is a rotary pressing cylinder.

[0036] Specifically, in this embodiment, the rotary pressing cylinder is model ACKL25x90, purchased from Airtac International Group. The model of the rotary pressing cylinder is not limited to this; any cylinder capable of rotary pressing can be used in the technical solution of this application.

[0037] During the press-fitting process, the adjusting module controls the pressing block 311 to move the bearing assembly 300. As the pressing block moves, it applies force to the bearing assembly 300, thus pressing the bearing assembly 300 onto the mounting shaft 201. Compared to the prior art, which uses a sleeve that contacts the bearing assembly 300 with a manual hammer for press-fitting, this method is more efficient. Simultaneously, the pressing assembly 30 and the support frame 10 work together to press the reflector bracket 200 firmly, preventing it from shaking during the press-fitting process and further improving efficiency.

[0038] The support frame 10 is also provided with limiting plates 13 at both ends along its length. The shape of the limiting plates 13 is adapted to the pressing block 21. Specifically, the bottom of the pressing block 21 is provided with a retaining plate 212 adapted to the limiting plate 13. The cross section of the limiting plate 13 is an inverted L-shaped structure. The limiting plate 13 limits the movement of the pressing block 21, so that the pressing block 21 drives the bearing 301 to be over-pressed and causes damage to the bearing 301.

[0039] Furthermore, the side wall of the limiting plate 13 is also provided with a positioning plate 14 that matches the abutment plate 212. The positioning plate 14 and the limiting plate 13 cooperate to form a cavity 15. The width of the cavity 15 matches the abutment plate 212, and when the abutment plate 212 enters the cavity 15, the bearing assembly 300 corresponds to the mounting shaft 201. Before pressing the bearing assembly 300 onto the mounting shaft 201, the pressing block 21 contacts the positioning plate 14 and the limiting plate 13 and corresponds to the cavity 15, thereby positioning the pressing block 21 before transferring the bearing 301 onto the mounting shaft 201 on the reflector bracket 200, improving the pressing efficiency.
