However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figure 1 - Figure 5 shown, the present utility model provides a toothed plate greasing structure, including a workbench 1, a toothed plate greasing component 2 is arranged on the surface of the workbench 1, the toothed plate greasing component 2 includes a first servo motor 201 and a bracket 202, the first servo motor 201 is connected to the bottom surface of one side of the workbench 1, the bracket 202 is connected to the output end of the first servo motor 201, an electric push rod 203 is connected to the upper surface of the bracket 202, the output end of the electric push rod 203 is connected to an upper greasing block 204, an upper oil injection hole 205 is arranged at the rear end of the upper greasing block 204, a lower greasing block 206 is connected to the lower surface of the bracket 202, a lower oil injection hole 207 is arranged at the rear end of the lower greasing block 206, a support bearing 208 is connected to the bottom of the bracket 202, a slideway 209 is connected to one side surface of the workbench 1, a fixed frame 210 is connected to the other side surface of the workbench 1, a workpiece 211 is arranged on the surface of the fixed frame 210, the first servo motor 201 is electrically connected to an external power supply through a control switch, a fixed connection is formed between the output end of the first servo motor 201 and the bracket 202, the bottom surface of the support bearing 208 is attached to the outer surface of the slideway 209, and a sliding connection is formed between the support bearing 208 and the slideway 209.

[0025] The effect achieved by the entire Embodiment 1 is that when greasing the workpiece 211 is required, first inject oil into the upper grease application block 204 through the upper oil injection hole 205, then inject oil into the lower grease application block 206 through the lower oil injection hole 207. After that, the workpiece 211 can be fixed on the surface of the fixing frame 210 first, and then the electric push rod 203 can be turned on through the control switch, so that the electric push rod 203 can push the upper grease application block 204 downward to the surface of the workpiece 211. At this time, the first servo motor 201 can be started, so that the first servo motor 201 can drive the bracket 202 to rotate through the output end. While the bracket 202 rotates, the bottom support bearing 208 will also slide in the slideway 209 to improve the stability of the bracket 202 during rotation. At the same time, under the control of the first servo motor 201, the upper grease application block 204 and the lower grease application block 206 will also apply grease on the surface of the workpiece 211 along the top of the tooth plate of the workpiece 211. And the first servo motor 201 can control the greasing area and the amount of grease of the workpiece 211 to adapt to greasing different workpieces 211, reduce the multiple investment in tooling, achieve cost reduction in manufacturing, and also improve the product quality.

[0026] Embodiment 2, as Figure 1 、 Figure 2 and Figure 6 shown, a lifting assembly 3 is arranged at the bottom of the workbench 1. The lifting assembly 3 includes sliding rods 301 and sliding sleeves 302. The bottom outer surfaces of the four groups of sliding rods 301 are all connected with sliding sleeves 302. The bottoms of the four groups of sliding sleeves 302 are fixedly connected with a bottom plate 307. Two groups of second servo motors 303 are symmetrically arranged on the surface of the bottom plate 307. The output ends of the second servo motors 303 are fixedly connected with one-way screw rods 304. A lifting block 305 is arranged on the surface of the one-way screw rod 304. A threaded hole 306 is opened inside the lifting block 305. The one-way screw rod 304 and the lifting block 305 form a threaded connection through the threaded hole 306. The two groups of second servo motors 303 are controlled by the same control switch.

[0027] The effect achieved by the entire Embodiment 2 is that when operators of different heights operate the tooth plate greasing component 2 to grease the workpiece 211, two groups of second servo motors 303 can be simultaneously turned on through the control switch, so that the two groups of second servo motors 303 can drive the two groups of one-way screws 304 to rotate simultaneously. Then, the one-way screws 304 can perform threaded rotation with the lifting blocks 305 through the threaded holes 306, thereby driving the workbench 1 to move upward. At the same time, the slide bars 301 will also slide within the slide sleeves 302 to improve the stability of the workbench 1 when it rises. When the height of the workbench 1 rises to the required height, just turn off the second servo motor 303. When it is necessary to lower the height of the workbench 1, the reverse rotation function of the second servo motor 303 can be turned on, and then drive the two groups of one-way screws 304 to perform reverse threaded rotation with the lifting blocks 305 simultaneously, so as to realize the lowering of the height of the workbench 1, avoiding the problem that the height of the existing workbench 1 cannot be adjusted, which makes it very inconvenient for operators of different heights to grease the workpiece 211.

[0028] Working principle: When it is necessary to grease the workpiece 211, the greasing area and the amount of grease of the workpiece 211 can be controlled by the first servo motor 201 to adapt to the greasing of different workpieces 211, reduce the multiple investment in tooling, achieve the reduction of manufacturing costs, and also improve the quality of the product. When operators of different heights operate the tooth plate greasing component 2 to grease the workpiece 211, the second servo motor 303 can be turned on to perform threaded rotation with the lifting block 305, and then drive the workbench 1 to adjust the height, avoiding the problem that the height of the existing workbench 1 cannot be adjusted, which makes it very inconvenient for operators of different heights to grease the workpiece 211.
