Description

Technical Field

[0001] This application relates to the field of polishing apparatus technology, specifically an internal gear ring polishing apparatus. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface. It is a finishing process that uses polishing tools and abrasive particles or other polishing media to modify the surface of a workpiece. Polishing cannot improve the dimensional accuracy or geometric accuracy of a workpiece, but aims to obtain a smooth surface or mirror gloss. Sometimes it is also used to eliminate gloss.

[0003] An existing patent (publication number: CN209078495U) discloses a polishing device for processing internal gear rings, including a base plate. A motor is fixedly mounted on the upper surface of the base plate via a mounting seat. A bevel gear a is fixedly mounted on the output shaft of the motor. The bevel gear a and bevel gear b mesh with each other. The bevel gear b is fixed on the outer surface of the rotating shaft a. The internal gear ring body is placed on a carrier plate. After adjusting the telescopic plate to a suitable position, the electric push rod is extended, thereby fixing the internal gear ring body under the action of the pressure block. By rotating the handle, the polishing cloth is brought into contact with the outer surface of the internal gear ring body. The motor is started, causing the internal gear ring body to start rotating, thereby polishing the outer surface of the internal gear ring body under the action of the polishing cloth. This utility model has the advantages of simple structure, high polishing efficiency, good polishing effect, and convenient and quick use, which greatly improves the production efficiency of internal gear ring bodies.

[0004] The aforementioned prior art uses a pressure block to fix the internal gear ring body. However, when dealing with large-diameter, thin-walled internal gear rings, the pressure block cannot position them with high quality. To solve this problem, an internal gear ring polishing device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an internal gear ring polishing device that uses an internal support positioning method to position the internal gear ring. This device is particularly suitable for polishing large-diameter thin-walled internal gear rings, which can further reduce the risk of deformation of thin-walled gears during processing and improve stability.

[0006] To achieve the above objectives, this application provides the following technical solution: an internal gear ring polishing device, comprising a base and an internal support mechanism. The internal support mechanism includes a positioning disk and a connecting rod rotatably sleeved on the inner wall of the positioning disk, as well as a worm gear and a disc fixedly connected to both ends of the connecting rod. The disc has three guide grooves inside. A worm gear meshing with the worm gear is installed on the bottom surface of the positioning disk. Three guide sleeves are fixedly connected to the upper surface of the positioning disk. A guide block is slidably sleeved on the inner wall of each guide sleeve. A transmission column is rotatably connected to the end of each of the three guide blocks that is close to each other. The three transmission columns are respectively sleeved on the inner walls of the three guide grooves. A rubber block is fixedly connected to the end of each of the three guide blocks that is far from each other. A rotating mechanism is provided between the base and the internal support mechanism, and a polishing mechanism is provided outside the internal support mechanism.

[0007] The above scheme, through the internal support mechanism, achieves the positioning of large-diameter thin-walled internal gear rings by internal support, reducing the external force clamping on the internal gear rings and preventing deformation. The internal gear rings are fitted onto the outside of three rubber blocks. Rotating the worm gear drives the worm wheel, connecting rod, and disc to rotate. The guide grooves allow the three guide blocks to move closer or further apart, thus enabling the internal support of internal gear rings of different sizes. The polishing mechanism is then adjusted according to the internal gear ring size. Finally, the rotating mechanism drives the positioning disc and the internally supported internal gear rings on the positioning disc to rotate, achieving efficient polishing.

[0008] Furthermore, a knob is fixedly connected to the shaft end of the worm gear.

[0009] The above solution allows for the increase of the contact area at the worm shaft end by setting a knob, making it easier to rotate the worm.

[0010] Furthermore, the rotating mechanism includes a rotating groove formed on the upper surface of the base, and three support columns are rotatably connected to the bottom surface of the positioning disk.

[0011] The above solution facilitates the rotation of the positioning disc, which in turn benefits the polishing of the internal gear ring.

[0012] Furthermore, each of the support columns is equipped with a ball on its bottom surface. The support columns and the ball are disposed inside the rotating groove, and the ball is in contact with the inner bottom wall of the rotating groove.

[0013] The above scheme allows the positioning disc to rotate above the base via the provided rotating groove, support column, and ball bearing.

[0014] Furthermore, a servo motor is fixedly connected to the upper surface of the base, a planar gear is fixedly connected to the output shaft end of the servo motor, and evenly distributed teeth are fixedly connected to the outer surface of the positioning disk, with the planar gear meshing with several teeth.

[0015] With the above scheme, when the servo motor starts, it will drive the planar gear to rotate. When the planar gear rotates, it can cause the positioning disk to rotate through the set teeth, thereby driving the inner gear ring supported on the upper surface of the positioning disk to rotate, which facilitates the efficient polishing of the inner gear ring.

[0016] Furthermore, the polishing mechanism includes two brackets fixedly connected to the upper surface of the base. Each bracket has a threaded rod threadedly connected to its inner wall, and a polishing block is rotatably connected to one end of each threaded rod that is close to the other.

[0017] The above method allows for adjustment of the polishing block's position when the threaded rod rotates, facilitating the polishing of internal gear rings of different sizes.

[0018] Furthermore, polishing cloths are fixedly connected to the sides of the two polishing blocks that are close to each other, and two positioning rods are slidably sleeved on the inner wall of each bracket, with the four positioning rods respectively fixedly connected to the outer surfaces of the two polishing blocks.

[0019] The above scheme allows for efficient polishing of the internal gear ring by using a polishing cloth, and the positioning rod enables stable movement of the polishing block.

[0020] Furthermore, an anti-slip pad is fixedly connected to the bottom surface of the base, and positioning holes are provided at the four corners of the base.

[0021] The above solution increases the friction between the base and the contact surface by setting anti-slip pads, thereby improving the stability of the base. By opening positioning holes, bolts can be used to position the device on the contact surface.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This internal gear ring polishing device uses an internal support mechanism to position a large-diameter thin-walled internal gear ring, reducing external force clamping and thus preventing deformation of the thin-walled internal gear ring. During operation, the internal gear ring is fitted onto the outside of three rubber blocks. Rotating the worm gear drives the worm wheel, connecting rod, and disc to rotate. Through the opened guide groove, the three guide blocks move closer or further apart, thus supporting the three rubber blocks in the inner wall of the internal gear ring. This achieves internal support for internal gear rings of different sizes. Then, the polishing mechanism is adjusted, and the rotating mechanism drives the positioning disc and the internal gear ring mounted on the positioning disc to rotate, thereby achieving efficient polishing.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This embodiment of an internal gear polishing device includes a base 1 and an internal support mechanism 2. The internal support mechanism 2 includes a positioning disk 201 and a connecting rod 202 rotatably sleeved on the inner wall of the positioning disk 201, as well as a worm gear 203 and a disc 204 fixedly connected to both ends of the connecting rod 202. The disc 204 has three guide grooves 205 inside. A worm 206 that meshes with the worm gear 203 is installed on the bottom surface of the positioning disk 201. The worm 206 and the worm gear 203 are combined together. It has the effects of deceleration and self-locking. The rotation of the worm 206 can cause the worm wheel 203 to rotate, but the worm wheel 203 cannot drive the worm 206 to rotate. Therefore, the connecting rod 202 can be limited. The rotation of the worm 206 can drive the connecting rod 202 and the disc 204 to rotate. A knob 211 is fixedly connected to the shaft end of the worm 206. By setting the knob 211, the contact area of ​​the shaft end of the worm 206 can be increased, making it easier to rotate the worm 206.

[0032] Please see Figure 2 , Figure 3 and Figure 4 Three guide sleeves 207 are fixedly connected to the upper surface of the positioning disk 201. A guide block 208 is slidably fitted on the inner wall of each guide sleeve 207. A transmission column 209 is rotatably connected to the end of the three guide blocks 208 that is close to each other. The three transmission columns 209 are respectively fitted on the inner wall of the three guide grooves 205. A rubber block 210 is fixedly connected to the end of the three guide blocks 208 that is far from each other. When the disk 204 rotates, the guide blocks 208 can move along the guide sleeves 207 through the guide grooves 205 and the transmission columns 209, thereby enabling the rubber blocks 210 to move. The three rubber blocks 210 can move closer to each other or further away from each other. The internal gear ring is fitted on the three rubber blocks 210, and the internal gear ring can be internally supported and positioned by the three rubber blocks 210, reducing the external force clamping on the internal gear ring and avoiding deformation of the thin-walled internal gear ring.

[0033] Please see Figure 2 , Figure 3 and Figure 4A rotating mechanism 3 is provided between the base 1 and the inner support mechanism 2. The rotating mechanism 3 includes a rotating groove 301 formed on the upper surface of the base 1. Three support columns 302 are rotatably connected to the bottom surface of the positioning disk 201, which facilitates the rotation of the positioning disk 201 and is beneficial to the polishing of the internal gear ring. A ball 303 is installed on the bottom surface of each support column 302. The support columns 302 and the ball 303 are set inside the rotating groove 301, and the ball 303 contacts the inner bottom wall of the rotating groove 301, so that the positioning disk 201 can move through the rotating groove 301, the support columns 302 and the ball 303 on the base 1. The base 1 is fixedly connected to the upper surface of the rotating platform. A servo motor 304 is fixedly connected to the upper surface of the platform. A planar gear 305 is fixedly connected to the output shaft of the servo motor 304. The outer surface of the positioning disk 201 is fixedly connected to evenly distributed teeth 306. The planar gear 305 meshes with several teeth 306. When the servo motor 304 starts, it will drive the planar gear 305 to rotate. When the planar gear 305 rotates, it can drive the positioning disk 201 to rotate through the set teeth 306, thereby driving the inner gear ring supported on the upper surface of the positioning disk 201 to rotate, which facilitates efficient polishing of the inner gear ring.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The inner support mechanism 2 is externally equipped with a polishing mechanism 4. The polishing mechanism 4 includes two supports 401 fixedly connected to the upper surface of the base 1. Each support 401 has a threaded rod 402 threadedly connected to its inner wall. Polishing blocks 403 are rotatably connected to the ends of the two threaded rods 402 that are close to each other. When the threaded rods 402 rotate, the position of the polishing blocks 403 can be adjusted, thereby facilitating the polishing of internal gear rings of different sizes. Polishing cloths 404 are fixedly connected to the sides of the two polishing blocks 403 that are close to each other. The inner wall of each support 401 can slide. Two positioning rods 405 are provided, and the four positioning rods 405 are fixedly connected to the outer surfaces of the two polishing blocks 403 respectively. By setting the polishing cloth 404, the internal gear ring can be polished efficiently. By setting the positioning rods 405, the polishing blocks 403 can be moved stably. The bottom surface of the base 1 is fixedly connected with an anti-slip pad 5. Positioning holes 6 are opened at the four corners of the base 1. By setting the anti-slip pad 5, the friction between the base 1 and the contact surface can be increased, and the stability of the base 1 can be improved. By opening the positioning holes 6, the device can be positioned on the contact surface with bolts.

[0035] In this embodiment, an internal gear ring polishing device uses an internal support mechanism 2 to position a large-diameter thin-walled internal gear ring, reducing external force clamping and preventing deformation. The internal gear ring is fitted onto the outside of three rubber blocks 210. Rotating the worm gear 206 drives the worm wheel 203, connecting rod 202, and disc 204 to rotate. The guide groove 205 allows the three guide blocks 208 to move closer or further apart, thus enabling the internal support of internal gear rings of different sizes through the three rubber blocks 210. The polishing mechanism 4 is then adjusted according to the internal gear ring. Finally, the rotating mechanism 3 drives the positioning disc 201 and the internal gear ring supported on the positioning disc 201 to rotate, achieving efficient polishing.

[0036] The working principle of the above embodiment is as follows: The internal gear ring to be polished is fitted onto the outside of the three rubber blocks 210. Then, the knob 211 is rotated. The rotation of the knob 211 drives the worm gear 206 to rotate. The worm wheel 203 meshing with it enables the connecting rod 202 and the disc 204 to rotate. When the disc 204 rotates, the three rubber blocks 210 can move closer or further apart through the guide groove 205 and the transmission column 209 installed on the guide block 208. In this way, the internal gear rings of different sizes can be internally supported and positioned on the positioning disc 201 by the three rubber blocks 210. Thus, the positioning disc 201 can move with the internal gear rings of different sizes. The rotation of the gear 404 causes the polishing cloth 404 to move toward the outer surface of the inner gear ring and come into contact with it. Finally, the servo motor 304 is started, which drives the positioning disk 201 and the inner gear ring supported on the upper surface of the positioning disk 201 to rotate. This allows the outer surface of the inner gear ring to be polished efficiently by the two polishing cloths 404. When the servo motor 304 is started, it drives the planar gear 305 to rotate. Through the set teeth 306, and in conjunction with the opened rotating groove 301 and the support column 302 and the ball 303 installed below the positioning disk 201, the positioning disk 201 can be stably rotated on the base 1.
