[0034] The oil injection mechanism 5 comprises a motor 51 fixedly connected to the inner wall of the speed reducer box 1, an output end of the motor 51 is fixedly connected with a rotating shaft 52, a circumferential surface of the rotating shaft 52 is fixedly penetrated with a half gear 53, the inside of the speed reducer box 1 is fixedly connected with a partition plate 54, a top of the partition plate 54 is provided with a sliding groove 55, the inside of the sliding groove 55 is slidably connected with a rack 56, the side of the rack 56 is fixedly connected with a connecting rod 57, the top of the partition plate 54 is fixedly connected with an oil injection tank 58, one end of the connecting rod 57 is fixedly connected with an extrusion plate 59, the bottom of the oil injection tank 58 is fixedly penetrated with a conveying pipe 510, one end of the conveying pipe 510 is fixedly connected with a spraying plate 511.

[0035] In some examples, further comprising: the inner wall of the speed reducer box 1 is fixedly connected with a reset spring 512, one end of the reset spring 512 away from the inner wall of the speed reducer box 1 is fixedly connected with the side of the rack 56, which is to ensure that the half gear 53 and the rack 56 are not engaged by the reset spring 512 to automatically reset.

[0036] The side of the connecting rod 57 and the side of the oil injection tank 58 are penetrated and slidably connected, and the side of the extrusion plate 59 and the inside of the oil injection tank 58 are slidably connected, which is to ensure that the movement of the connecting rod 57 can move the extrusion plate 59 inside the oil injection tank 58.

[0037] The side of the rack 56 is elastically connected to the inner wall of the speed reducer box 1 by the reset spring 512, and the initial state of the reset spring 512 is a relaxed state, which is to ensure that the reset spring 512 is automatically reset after being stressed.

[0038] The circumferential surface of the half gear 53 and the side of the rack 56 are engaged with each other, and the bottom of the spraying plate 511 is located directly above the worm 3, and the circumferential surface of the half gear 53 and the side of the rack 56 are engaged with each other to ensure that the rotation of the half gear 53 can move the rack 56, and the bottom of the spraying plate 511 is located directly above the worm 3 to ensure that the oil sprayed by the spraying plate 511 can lubricate the surface of the worm 3.

[0039] For example, as Figures 1-5As shown, when the speed reducer box 1 needs to be used, the worm wheel 4 and the worm 3 are started at the same time, the motor 51 is started, the output end of the motor 51 rotates, the output end of the motor 51 drives the rotating shaft 52 to rotate, the rotating shaft 52 drives the half gear 53 to rotate, the half gear 53 is engaged with the rack 56, the half gear 53 drives the rack 56 to move in the sliding groove 55, the rack 56 moves through the connecting rod 57 to drive the extrusion plate 59 to move in the oil injection tank 58, the extrusion plate 59 moves to press the oil in the oil injection tank 58, so that the oil is forced to enter the inside of the spraying plate 511 through the delivery pipe 510, and finally the lubricating oil is injected into the transmission part of the worm 3 to form an oil film, thereby reducing friction and heat accumulation. When the half gear 53 continues to rotate to the toothless area, the rack 56 is not engaged with the half gear 53, and the rack 56 is reset by the elasticity of the reset spring 512, so that the oil injection tank 58 stops supplying oil, and the half gear 53 is continuously rotated to indirectly discharge the oil from the oil injection tank 58, preventing the lubricating oil from accumulating in one place of the worm 3.

[0040] As Figures 1-5 As shown, it shows an oil injection device for worm and gear speed reducer machining in another embodiment of the present disclosure, which is basically the same as the above technical solution, so only the differences are described, the cleaning mechanism 6, the cleaning mechanism 6 includes a threaded rod 61, one end of the threaded rod 61 is fixedly connected to one end of the rotating shaft 52, the circumferential surface of the threaded rod 61 is threadedly connected with a threaded sleeve 62, the bottom of the threaded sleeve 62 is fixedly connected with a moving rod 63, the top of the partition plate 54 is provided with a moving groove 64, the side surface of the moving rod 63 is slidably connected with the inside of the moving groove 64, one end of the moving rod 63 away from the bottom of the threaded sleeve 62 is fixedly connected with a cleaning brush 65, and the side surface of the glass observation plate 66 is provided with a glass observation plate 66. The function of the cleaning mechanism 6 is to clean the oil adhered to the surface of the glass observation plate 66.

[0041] In some examples, further comprising: the inside of the speed reducer box 1 is fixedly connected with a filter plate 67, and the side surface of the cleaning brush 65 is fixedly connected with a scraper 68, which is to filter impurities from the oil used.
