[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses an air pump to draw air from the support cylinder, creating a negative pressure inside the support cylinder that draws air from the protective cover. This allows the air inside the support cover to be drawn in, making it easier to collect and clean the dust generated during grinding, thus preventing dust from spilling out and causing pollution.

[0014] 2. This utility model uses an electric motor to drive the lead screw to rotate and the top plate to make threaded movements, which in turn causes the compression spring to elastically squeeze the slider, and then the slide plate drives the intermediate shaft to elastically contact the grinding strip through the connecting cylinder, thus preventing the grinding strip from separating from the intermediate shaft after grinding.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-2 A grinding device for intermediate shaft processing includes a worktable 1, a support plate 2 fixedly connected to the upper end of the worktable 1, a motor 3 fixedly installed at the left end of the support plate 2, a shaft of the motor 3 passing through the support plate 2 and rotatably connected to the support plate 2, a dust removal mechanism 4 provided on the shaft of the motor 3, an adjustment mechanism 5 provided on the worktable 1, a slide plate 6 provided on the adjustment mechanism 5, a connecting cylinder 7 fixedly connected inside the slide plate 6, a square rod 8 slidably connected inside the connecting cylinder 7, a clamping plate 9 fixedly connected to one end of the square rod 8, a connecting plate 10 fixedly connected to the other end of the square rod 8, a screw cylinder 11 fixedly connected to the surface of the connecting plate 10, a bidirectional screw 12 threadedly connected inside the screw cylinder 11, a limiting plate 13 fixedly connected to the right end of the slide plate 6, the limiting plate 13 and the bidirectional screw 12 rotatably connected, and the bidirectional screw 12 is limited by the limiting plate 13.

[0022] Please see Figures 1-3The dust removal mechanism 4 includes a support cover 41. The right end of the shaft of the motor 3 is fixedly connected to the support cover 41. A grinding strip 42 is fixedly connected inside the support cover 41. A protective cover 43 is installed on the outside of the support cover 41 through a sealed bearing. A connecting pipe 44 is fixedly connected inside the protective cover 43. The connecting pipe 44 passes through the support plate 2 and is fixedly connected to the support plate 2. The connecting pipe 44 is fixedly connected to the support cylinder 45. The support cylinder 45 and the protective cover 43 are connected by the connecting pipe 44. The support cylinder 45 is fixedly installed on the left end of the support plate 2. A filter screen 46 is fixedly connected inside the support cylinder 45. An air pump 47 is fixedly installed on the left end of the support cylinder 45. The suction pipe of the air pump 47 passes through the support cylinder 45 and is fixedly connected to the support cylinder 45. By the air pump 47 sucking air from the support cylinder 45, the negative pressure inside the support cylinder 45 sucks air from the protective cover 43, thereby sucking air from the support cover 41. This makes it easier to collect and clean the dust generated by grinding, and avoids dust spillage and pollution.

[0023] Please see Figure 1 , Figure 2 , Figure 4 The adjusting mechanism 5 includes a protrusion 51. The lower end of the slide plate 6 is fixedly connected to the protrusion 51, which is slidably connected to the worktable 1. The protrusion 51 supports the slide plate 6. The lower end of the support plate 2 is fixedly connected to a slider 52, which is slidably connected to the worktable 1. A motor 53 is fixedly installed on the right end of the worktable 1. The output end of the motor 53 passes through the worktable 1 and is rotatably connected to it. The left end of the output end of the motor 53 is fixedly connected to a lead screw 54, which is rotatably connected to the worktable 1. The outer side of the lead screw 54... A top plate 55 is connected by a thread, and a compression spring 56 is provided on the outside of the lead screw 54. One end of the compression spring 56 is fixedly connected to the slider 52, and the other end of the compression spring 56 is fixedly connected to the top plate 55. By setting the compression spring 56, the slider 52 is elastically pressed. The motor 53 drives the lead screw 54 to rotate and the top plate 55 to make threaded movement, which in turn causes the compression spring 56 to elastically squeeze the slider 52. This causes the slide plate 6 to drive the intermediate shaft to elastically contact the grinding strip 42 through the connecting cylinder 7, thus preventing the grinding strip 42 from separating from the intermediate shaft after grinding.

[0024] The specific implementation process of this utility model is as follows: In use, the intermediate shaft passes through the connecting cylinder 7, and the bidirectional screw 12 is manually rotated. The bidirectional screw 12 rotates and the screw cylinder 11 makes a threaded movement, which in turn causes the screw cylinder 11 to drive the connecting plate 10 to move by 1. The connecting plate 10 drives the square rod 8 to move, and the square rod 8 drives the clamping plate 9 to move, so that the clamping plate 9 can move and contact the intermediate shaft, thereby fixing the intermediate shaft. Then, the motor 3 is started, and the motor 3 drives the support cover 41 to rotate. The support cover 41 drives the grinding strip 42 to rotate, and the motor 53 is started. The electric motor 53 drives the lead screw 54 to rotate, and the rotation of the lead screw 54 and the top plate 55 make threaded movements, which in turn causes the top plate 55 to move. The movement of the top plate 55 compresses the compression spring 56, which in turn causes the compression spring 56 to elastically compress the slider 52. This causes the slide plate 6 to drive the intermediate shaft to elastically contact the grinding strip 42 through the connecting cylinder 7, preventing the grinding strip 42 from separating from the intermediate shaft after grinding. The air pump 47 is started, and the air pump 47 draws air from the support cylinder 45. The negative pressure in the support cylinder 45 draws air from the protective cover 43, which in turn draws air from the support cover 41. This makes it easier to collect and clean the dust generated during grinding, preventing dust from overflowing and causing pollution.
