DETAILED DESCRIPTION

[0015] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, a transmission gear omnidirectional grinding and polishing device comprises a processing table 5, on which a station slot 6 for placing a transmission gear 101 is arranged, and the transmission gear 101 comprises a gear body 1, a shaft hole 2 is arranged at the middle position of the gear body 1, a tooth portion 3 is arranged at the edge of the gear body 1, and an annular recessed portion 4 is arranged on both side walls of the gear body 1; A positioning column 7 corresponding to the shaft hole 2 of the transmission gear 101 is provided at the middle position of the station slot 6. When the transmission gear 101 is placed in the station slot 6, the positioning column 7 is correspondingly inserted into the shaft hole 2. A rotating mechanism 8 is also installed above the station slot 6, and a rotating seat 9 is installed on the main shaft of the rotating mechanism 8, and a lifting mechanism 10 is correspondingly installed on the rotating seat 9. The main shaft of the lifting mechanism 10 extends downward and a lifting plate 11 is correspondingly installed. The position of the lifting plate 11 corresponds to the position of the station slot 6 below, and a grinding roller shaft 12 is correspondingly installed at the lower end of the lifting plate 11. The grinding roller shaft 12 corresponds to the position of the transmission gear 101 placed in the station slot 6 below, and the grinding roller shaft 12 is also provided with a convex portion 13 corresponding to the position of the concave portion 4, and the grinding roller shaft 12 can rotate accordingly; After the lifting plate 11 moves downward, the grinding roller shaft 12 is pressed against the upper end surface of the transmission gear 101, and the protrusion 13 is pressed into the recessed portion 4. The rotating mechanism 8 drives the grinding roller shaft 12 to rotate, and the end surface of the transmission gear 101 is ground and polished.

[0017] like Figure 4 As shown, there are two frosting roller shafts 12 on the lower end surface of the lifting plate 11, and the two frosting roller shafts 12 are symmetrically arranged. The lower end surface of the lifting plate 11 is provided with a mounting groove 14 that is adapted to the size of the frosting roller shaft 12. The frosting roller shaft 12 is correspondingly arranged in the mounting groove 14 through a rotating axis, and the frosting roller shaft 12 can rotate accordingly.

[0018] like Figure 5 As shown, a clamping mechanism 15 is also installed in the processing table 5. The main shaft of the clamping mechanism 15 extends inwardly into the work station slot 6, and an arc-shaped clamping plate 16 is installed at the end of the shaft. A clamping tooth 17 is also provided on the inner end surface of the clamping plate 16. The clamping tooth 17 is arranged to be compatible with the size of the tooth portion 3 of the transmission gear 101. When the transmission gear 101 is placed in the work station slot 6, the clamping mechanism 15 clamps and fixes the transmission gear 101 through the clamping teeth 17 on the clamping plate 16.

[0019] There are four clamping mechanisms 15 with even intervals in total; and each clamping plate 16 is also provided with a clamping belt 18, the two ends of the clamping belt 18 are detachably arranged at the two ends of the clamping plate 16, and the clamping teeth 17 are located between the clamping belt 18 and the clamping plate 16. When the clamping teeth 17 are pressed into the tooth portion 3 of the transmission gear 101, the clamping belt 18 is also pressed into the tooth portion 3 of the transmission gear 101.

[0020] The pressing belt 18 is configured as a silicone elastic belt, and the pressing teeth 17 on the pressing plate 16 are configured to be made of a hard PVC material; and a receiving groove 19 for the pressing plate 16 and the pressing teeth 17 is also configured in the station groove 6 .

[0021] The pressing belt 18 is configured as a frosted belt, and the pressing teeth 17 on the pressing plate 16 are configured to be made of a hard PVC material; and a receiving groove 19 for the pressing plate 16 and the pressing teeth 17 is also provided in the station groove 6 .

[0022] An annular top plate 20 is also provided at the bottom of the work station slot 6, and a pressing mechanism 21 is also installed in the processing table 5. The main axis of the pressing mechanism 21 is upwardly connected to the annular top plate 20. The annular top plate 20 can be pushed upward by the pressing mechanism 21, thereby pushing up the transmission gear 101 in the work station slot 6.

[0023] like Figure 6 As shown, the positioning column 7 in the work station slot 6 is a rotating column structure, and a rotating component 22 is correspondingly installed in the processing table 5, and the rotating component 22 can drive the positioning column 7 to rotate accordingly; and the column surface of the positioning column 7 is also provided with bristles 23, and the burrs in the shaft hole 2 can be brushed off by the bristles 23.

[0024] The specific working principle of the present invention is as follows: the transmission gear grinding and polishing processing device of the present invention is set for the transmission gear of the present invention, and the specific structural setting of the transmission gear of the present invention is as follows: it includes a gear body, an axial hole is set at the middle position of the gear body, a tooth portion is set at the edge of the gear body, and an annular recessed portion is set on both side walls of the gear body; specifically, it includes an outer tooth portion, a middle axial hole and an annular recessed portion on both side walls.

[0025] The grinding and polishing processing device for the transmission gear is provided with a work station slot on the processing table and a positioning column in the work station slot. When the transmission gear is placed specifically, the positioning column is inserted into the shaft hole to position the transmission gear, and then the transmission gear is fixed by the clamping mechanism outside the work station slot. Then the lifting mechanism above drives the lifting plate to descend as a whole, and presses the grinding roller shaft on the lower end surface of the lifting plate onto the upper end surface of the transmission gear. At the same time, the corresponding raised portion is also pressed into the corresponding recessed portion. Then the lifting plate is driven to rotate accordingly by the rotating mechanism, and the end surface of the transmission gear is frosted by the grinding roller shaft and the raised portion to eliminate burrs and other residual problems.

[0026] In the process of grinding and polishing the transmission gear, the transmission gear is clamped and fixed by a clamping mechanism arranged outside the station slot. The arrangement of the clamping mechanism of the present invention is completely different from the prior art. A clamping plate is installed on the main shaft of the clamping mechanism of the present invention, and a clamping tooth is arranged on the inner end surface of the clamping plate. The present invention can directly clamp the transmission gear by the clamping tooth, but it may cause damage to the tooth part and fail to remove the burr of the tooth part.

[0027] Therefore, the present invention arranges a pressing belt on the pressing plate. The arrangement of the pressing belt can protect the tooth portion on the one hand. When the pressing plate and the pressing teeth are pressed, they are pressed into the tooth portion together with the pressing belt, which can effectively prevent the tooth portion from being damaged due to excessive pressure. Another more important point is that when the pressing belt is pressed, burrs at the tooth gaps in the tooth portion can be removed accordingly. The burrs can be removed by the action of pressure. This design can fix the transmission gear on the one hand, prevent damage to the transmission gear on the other hand, and further remove the burrs in the tooth portion while pressing.

[0028] In addition, the compression belt can be specifically configured as an elastic silicone elastic belt, and then the compression teeth can be configured to be made of hard materials instead of metal compression teeth. After such configuration, the silicone elastic belt can be pressed into the teeth more smoothly, and the compression teeth will not damage the silicone elastic belt. Similarly, configuring the compression belt as a frosted belt or a wear-resistant felt structure also has a better grinding and polishing effect.

[0029] The present invention also provides an annular top plate and a pressing mechanism. The annular top plate and the pressing mechanism of the present invention have two functions. One function is to lift the transmission gear upward to facilitate the taking and placing of the transmission gear; the other function is to cooperate with the clamping mechanism to grind and polish the teeth of the transmission gear.

[0030] When performing the above-mentioned treatment, first move the upper lifting plate upward, and when the clamping mechanism on the outer side of the work station slot is not disclosed, the annular top plate is pressed by the pressing mechanism at the bottom, so that the annular top plate is pushed upward, thereby pushing the transmission gear upward. In this lifting process, since the clamping teeth and the clamping belt are still located on the inner side of the tooth portion, the tooth portion is rubbed by the clamping belt accordingly. When the transmission gear is completely ejected, the burrs in the tooth portion are correspondingly removed by the friction of the clamping belt, thereby realizing the burr removal operation in the tooth portion.

[0031] In addition to the processing of the two side surfaces and the tooth position of the transmission gear, the shaft hole position also needs to be processed. In the present invention, the positioning column is correspondingly extended into the shaft hole. The present invention installs the positioning column on the rotating component, and provides bristles on the outer surface of the positioning column. When the transmission gear is fixed in the work station slot, the positioning column can be driven to rotate by the rotating component, and the bristles on the positioning column can remove the burrs in the shaft hole, thereby realizing the grinding and polishing treatment of the inside of the shaft hole.

[0032] Through the cooperation of the above-mentioned components, the present invention can realize the grinding and polishing of the internal shaft hole of the transmission gear, the end faces on both sides of the gear and the teeth, effectively remove the burrs on various parts of the transmission gear, and realize the all-round grinding and polishing of the transmission gear in the present invention. The structural setting is ingenious and reasonable, and it is easy to use.

[0033] The above specific implementation is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
