Description

Technical Field

[0001] The utility model relates to the technical field of polishing jigs, in particular to a polishing jig for spherical products. Background Technique

[0002] A polishing jig for spherical products is a tool or device specifically used for precisely polishing and finely processing the surface of spherical objects. Such jigs are widely used in various industrial fields, such as bearing manufacturing, medical devices, aerospace, and precision equipment.

[0003] When polishing spherical products currently, a profiling fixture needs to be used in cooperation. The profiling fixture clamps and fixes the inner and outer surfaces of the spherical product through a concave fixture and a convex fixture. When polishing the outer wall of the spherical product, due to the presence of the fixture, it will block the operation path of the operator to a certain extent, which makes it difficult to fully polish some local parts of the spherical product. To solve this problem, the operator has to frequently readjust the clamping part to ensure that each part can be properly polished. This repeated adjustment process not only increases the complexity of the operation but also significantly reduces the production efficiency.

[0004] Therefore, a polishing jig for spherical products is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a polishing jig for spherical products to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A polishing jig for spherical products, comprising: a fixed rod,

[0008] A spherical shell, arranged on the left side of the fixed rod;

[0009] A support mechanism, arranged on one side of the fixed rod, used for supporting and fixing the spherical shell. The support mechanism includes a screw rod fixedly installed at the left end of the fixed rod, and a movable sleeve is slidably sleeved on the outer wall of the screw rod;

[0010] A reinforcement mechanism, arranged outside the support mechanism, used for further fixing the spherical shell. The reinforcement mechanism includes a fixed box arranged on one side of the movable sleeve.

[0011] Preferably, a fixed block is fixedly installed at the left end of the screw rod through a bolt. Four slots are formed on the outer wall of the fixed block, and the left side surface of the fixed block is slidably connected to the inner wall of the spherical shell.

[0012] Preferably, connecting rods are respectively hinged to the inner walls of the four trough bodies I. The other ends of the four connecting rods are respectively hinged to connecting blocks. The sides of the four connecting blocks are in frictional connection with the inner wall of the spherical shell. The connecting blocks are made of POM.

[0013] Preferably, four trough bodies II are formed in the outer wall of the moving sleeve. One ends of the outer walls of the four trough bodies II are respectively hinged to the inner walls of the four connecting blocks. A nut is in threaded connection with the outer wall of the screw rod. The side of the nut is movably connected with the side of the moving sleeve.

[0014] Preferably, the number of the fixing boxes is four. One end faces of the four fixing boxes are respectively fixedly connected to the sides of the four connecting rods. Moving plates are respectively slidably connected to the inner walls of the four fixing boxes.

[0015] Preferably, springs are respectively fixedly installed on the sides of the four moving plates. The other ends of the four springs are respectively fixedly connected to the inner walls of one ends of the four fixing boxes. A support rod is fixedly installed on the other side of the moving plate.

A support plate is fixedly installed at one end of the support rod.

[0016] Preferably, a rubber pad is fixedly installed on the outer wall of the support plate. The outer wall of the rubber pad is in frictional connection with the inner wall of the spherical shell.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] In the utility model, the spherical shell is sleeved on the fixing block. The fixing block is in contact with the inner wall of the spherical shell. The nut is rotated. While rotating, the nut moves, driving the moving sleeve to move. The moving sleeve drives the connecting block and the connecting rod to rotate by a certain angle, so that the outer wall of the connecting block is in contact with the inner wall of the spherical shell and supports the inner wall of the spherical shell, fixing the spherical shell without blocking the outer wall of the spherical shell, ensuring that each part can be properly polished without adjusting the supporting and fixing parts of the spherical shell, not only reducing the complexity of the operation, but also significantly improving the production efficiency.

[0019] When the spherical shell is supported and fixed by the connecting block, the connecting rod drives the fixing box to rotate by a certain angle, and at the same time drives the rubber pad on the support plate to support the inner wall of the spherical shell. Through the elastic force exerted by the spring on the moving plate, the moving plate exerts a thrust on the support plate and the rubber pad through the support rod, further supporting and fixing the spherical shell, so that when the spherical shell is polished, it is not easy to shift, improving the polishing quality.

[0029] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] As Figures 1-5 shown, the present application provides a polishing jig for spherical products, including a fixed rod 1, a sphere shell 101, a support mechanism 2 arranged on the left side of the fixed rod 1, and a reinforcement mechanism 3 arranged on one side of the fixed rod 1 for supporting and fixing the sphere shell 101. The support mechanism 2 includes a screw rod 201 fixedly installed at the left end of the fixed rod 1, and a moving sleeve 207 is slidably sleeved on the outer wall of the screw rod 201. The reinforcement mechanism 3 is arranged outside the support mechanism 2 for further fixing the sphere shell 101, and the reinforcement mechanism 3 includes a fixing box 301 arranged on one side of the moving sleeve 207.

[0032] Specifically, as Figures 1-3As shown in the figure, a fixing block 202 is fixedly installed at the left end of the screw rod 201 through a bolt 203. Four first grooves 204 are formed on the outer wall of the fixing block 202. The left side surface of the fixing block 202 is slidably connected to the inner wall of the spherical shell 101.

[0033] In this embodiment: By providing the bolt 203, the bolt 203 can be conveniently disassembled, and thus the fixing block 202 can be conveniently separated from the screw rod 201.

[0034] Specifically, as Figures 1-3 shown, connecting rods 205 are respectively hinged to the inner walls of the four first grooves 204. The other ends of the four connecting rods 205 are respectively hinged to connecting blocks 206. The side surfaces of the four connecting blocks 206 are frictionally connected to the inner wall of the spherical shell 101. The material of the connecting block 206 is POM.

[0035] In this embodiment: By providing the connecting rods 205, they can cooperate with the connecting blocks 206 to rotate, so that the connecting blocks 206 can support the inner wall of the spherical shell 101.

[0036] Specifically, as Figures 1-3 shown, four second grooves 208 are formed on the outer wall of the moving sleeve 207. The inner walls of the four second grooves 208 are respectively hinged to the outer walls of one ends of the four connecting blocks 206. A nut 209 is threadedly connected to the outer wall of the screw rod 201. The side surface of the nut 209 is movably connected to the side surface of the moving sleeve 207.

[0037] In this embodiment: By providing the nut 209, the position of the moving sleeve 207 can be adjusted, so that the moving sleeve 207 moves to an appropriate position to ensure that the connecting block 206 supports and fixes the spherical shell 101.

[0038] Specifically, as Figures 4-5 shown, the number of fixing boxes 301 is four. One end surfaces of the four fixing boxes 301 are respectively fixedly connected to the side surfaces of the four connecting rods 205. Moving plates 302 are respectively slidably connected to the inner walls of the four fixing boxes 301.

[0039] In this embodiment: By providing that the moving plates 302 are respectively slidably connected to the inner walls of the fixing boxes 301, the moving plates 302 can move to appropriate positions as needed.

[0040] Specifically, as Figures 4-5 shown, springs 303 are respectively fixedly installed on the side surfaces of the four moving plates 302. The other ends of the four springs 303 are respectively fixedly connected to one end inner walls of the four fixing boxes 301. A support rod 304 is fixedly installed on the other side surface of the moving plate 302. The other end of the support rod 304 slidably penetrates through the inner wall of the fixing box 301 and extends to the outside of the fixing box 301. A support plate 305 is fixedly installed at one end of the support rod 304.

[0041] In this embodiment, by providing the spring 303, an elastic force can be applied to the moving plate 302.

[0042] Specifically, as Figures 4-5 shown, a rubber pad 306 is fixedly installed on the outer wall of the support plate 305, and the outer wall of the rubber pad 306 is frictionally connected to the inner wall of the spherical shell 101.

[0043] In this embodiment, by providing the rubber pad 306, the friction with the inner wall of the spherical shell 101 can be increased and damage to the inner wall of the spherical shell 101 can be prevented.

[0044] The specific solution of this scheme is as follows: The spherical shell 101 is sleeved on the fixed block 202, and the fixed block 202 is in contact with the inner wall of the spherical shell 101. The nut 209 is rotated. While rotating, the nut 209 moves, driving the moving sleeve 207 to move. The moving sleeve 207 drives the connecting block 206 and the connecting rod 205 to rotate by a certain angle, so that the outer wall of the connecting block 206 is in contact with the inner wall of the spherical shell 101 and supports the inner wall of the spherical shell 101, so that the spherical shell 101 is fixed and will not block the outer wall of the spherical shell 101, ensuring that each part can be properly polished without adjusting the supporting and fixing parts of the spherical shell 101. This not only reduces the complexity of the operation but also significantly improves the production efficiency. When the connecting block 206 supports and fixes the spherical shell 101, the connecting rod 205 drives the fixed box 301 to rotate by a certain angle, and at the same time drives the rubber pad 306 on the support plate 305 to support the inner wall of the spherical shell 101. Through the elastic force applied by the spring 303 to the moving plate 302, the moving plate 302 applies a thrust to the support plate 305 and the rubber pad 306 through the support rod 304, further supporting and fixing the spherical shell 101, so that when the spherical shell 101 is polished, it is not easy to shift and the polishing quality is improved.
