[0028] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] like Figures 1 to 6 As shown, this application provides a trimming device for processing a gearbox housing, including a conveyor track 100, a moving device 110 and a worktable 300. The moving device 110 is used to drive the gearbox housing 120 to move on the conveyor track 100. The gearbox housing 120 is detachably connected to the moving device 110. The device also includes a trimming component 200, which is used to grind and trim the surface of the gearbox housing 120.

[0031] The trimming assembly 200 includes a trimming frame 210 and a water collection tank 220;

[0032] The trimming frame 210 is a U-shaped frame with two parallel water spray seats 230 fixed on its side, and the gearbox housing 120 is located between the two water spray seats 230.

[0033] Each of the water spray bases 230 has multiple nozzles 231 fixed on the side near the gearbox housing 120. The nozzles 231 are used to sandblast the surface of the gearbox housing 120.

[0034] A water tank 310 is positioned inside the workbench 300. The water tank 310 is filled with liquid containing abrasive particles. A second water pipe 312 is fixed to one side of the water tank 310. A water pump is fixed on the water tank 310. The water pump sends the liquid in the water tank 310 into the second water pipe 312. A branch pipe 3121 is fixed to the unused end of the second water pipe 312. The branch pipe 3121 has two water outlets. One of the water outlets of the branch pipe 3121 extends into a water spray seat 230.

[0035] The water collection tank 220 is fixed to the bottom of the trimming frame 210 and is used to collect liquid after use.

[0036] It is worth noting that by pumping a liquid containing abrasive particles into water pipe 312, and by sending the liquid containing abrasive particles into spray base 230 through branch pipe 3121, and by spraying the liquid containing abrasive particles onto the surface of gearbox housing 120 through nozzle 231, the surface and edges of gearbox housing 120 can be trimmed.

[0037] Specifically, such as Figures 4 to 6 As shown, the gearbox housing 120 includes a concave surface and a convex surface, a water spray seat 230 is parallel to the concave surface of the gearbox housing 120, and a water spray seat 230 is parallel to the convex surface of the gearbox housing 120.

[0038] It is easy to understand that by using two water sprayers 230 to grind and repair the concave and convex surfaces of the gearbox housing 120 respectively, the concave and convex surfaces of the gearbox housing 120 can be ground and repaired at the same time.

[0039] Specifically, such as Figures 1 to 4 As shown, the edge of the gearbox housing 120 is fixed with a plurality of mounting holes 121, and a nozzle 231 is parallel to a mounting hole 121.

[0040] It is worth noting that the multiple nozzles 231 can grind and trim the mounting holes 121 on the edge of the gearbox housing 120, and grind and trim the burrs inside the holes of the mounting holes 121.

[0041] Specifically, such as Figures 2 to 6 As shown, a water pipe 311 is fixed to one side of the water tank 310, and a water pump is fixed on the water pipe 311. The water pump is fixed in the water tank 310, and the unused end of the water pipe 311 extends into the water collection tank 220.

[0042] It should be noted that by pressurizing the water pipe 311 through a water pump, the water used in the water collection tank 220 is returned to the water tank 310, which facilitates the recycling of the water used in the water tank 310.

[0043] Specifically, such as Figures 1 to 6As shown, two parallel flexible plates 211 are fixed on one side of the opening end of the trimming frame 210, and there is a gap between the two flexible plates 211. The flexible plates 211 are used to prevent the sprayed water from splashing everywhere.

[0044] It is worth noting that after the gearbox housing 120 enters the trimming frame 210, it can push open the soft plate 211 and enter the trimming frame 210.

[0045] Specifically, such as Figures 3 to 6 As shown, two gas bags 212 are fixed on the other side of the opening end of the trimming frame 210. There is a gap between the gas bags 212, which is between 8cm and 10cm, and does not affect the passage of the gearbox housing 120 through the gas bags 212.

[0046] Each of the gas bladders 212 has a cleaning cotton 213 fixed to its side near the gearbox housing 120. The cleaning cotton 213 is used to clean water stains on the surface of the gearbox housing 120 after polishing.

[0047] It is worth noting that the cleaning cotton 213 is a sponge. The cleaning cotton 213 has high deformation strength and can adapt well to the gearbox housing 120.

[0048] Specifically, such as Figures 4 to 6 As shown, an air pump 215 is fixed on the trimming frame 210, an air inlet pipe 214 is fixed on the output end of the air pump 215, and a distribution pipe 2141 is fixed on the empty end of the air inlet pipe 214.

[0049] The distribution pipe 2141 has two air outlets. One air outlet of the distribution pipe 2141 extends into a gas soft bag 212. The connection between the distribution pipe 2141 and the gas soft bag 212 is airtight and fixed.

[0050] In actual use, the gearbox housing processing trimming device of this application embodiment positions the gearbox housing 120 on the moving device 110. The moving device 110 drives the gearbox housing 120 to move on the conveying track 100, and the gearbox housing 120 is conveyed to the trimming frame 210. The liquid in the water tank 310 is sent from the second water pipe 312 into the branch pipe 3121 by the water pump. The liquid containing abrasive particles is sent into the spray seat 230. The liquid containing abrasive particles is sprayed out through the nozzle 231 to remove burrs on the concave and convex surfaces of the gearbox housing 120. At the same time, the burrs on the mounting hole seat 121 on the edge of the gearbox housing 120 are removed. The sprayed liquid falls into the water collection tank 220. Then, the water pipe 311 is pressurized by the water pump, and the used water in the water collection tank 220 is sent into the water tank 310 to facilitate the recycling of the used liquid.

[0051] After the gearbox housing 120 is polished, the moving device 110 continues to move it. When it passes the cleaning cotton 213, air is introduced into the air intake pipe 214 by the air pump 215, causing the distribution pipe 2141 to inflate the gas soft bag 212 and make it expand. This moves the cleaning cotton 213 closer to the gearbox housing 120, so that the cleaning cotton 213 completely contacts the concave and convex surfaces of the gearbox housing 120, absorbing the water stains on the surface of the gearbox housing 120. Then, air is extracted from the air intake pipe 214, causing the gas soft bag 212 to reset. The moving device 110 continues to move the gearbox housing 120. This process can remove burrs from the surface and edges of the gearbox housing 120, and at the same time dry the water stains on the surface of the gearbox housing 120, improving processing efficiency.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
