[0044] For the second embodiment, please refer to Figure 1-Figure 9The present invention provides a technical solution: on the basis of embodiment 1, the tightening device 3 includes an air blowing pipe 31 and an air suction pipe 32, one end of the air blowing pipe 31 and the air suction pipe 32 are both connected to a diverter plate 33, one end of the diverter plate 33 is fixedly connected to a support column 34, one end of the support column 34 away from the diverter plate 33 is fixedly connected to a limiting plate 35, the side of the limiting plate 35 away from the support column 34 is fixedly connected to an electric telescopic rod 36, the end of the electric telescopic rod 36 away from the limiting plate 35 is fixedly connected to a tightening plate 37, the bottom of the diverter plate 33 is fixedly connected to a positioning bracket 38, and a dust suction device 39 is installed on the side of the diverter plate 33 close to the support column 34.

[0045] One end of the positioning bracket 38 away from the diverter plate 33 is fixedly connected to the top of the processing table 1 , and the blowing pipe 31 and the suction pipe 32 are symmetrically distributed at both ends of the grinding device 2 .

[0046] The dust suction device 39 includes a threaded sleeve 391, the outer side of the threaded sleeve 391 is rotatably connected to a rotating sleeve 392 via a bearing, the outer side of the rotating sleeve 392 is rotatably connected to an arc rod 393 via a rotating seat, the end of the arc rod 393 away from the rotating sleeve 392 is fixedly connected to a ventilation pipe 394, the two ends of the ventilation pipe 394 are respectively connected to a diverter pipe 396 and a ventilation nozzle 397 via a connecting device 395, and a limiting device 398 is installed on the outer side of the ventilation nozzle 397.

[0047] There are two groups of threaded sleeves 391, which are respectively sleeved on the outside of the blowing pipe 31 and the suction pipe 32. The outsides of the blowing pipe 31 and the suction pipe 32 are threadedly connected to the inner wall of the threaded sleeve 391. The end of the diverter pipe 396 away from the connecting device 395 is connected to the side of the diverter plate 33. There are multiple groups of arc rods 393, which are evenly distributed on the outside of the rotating sleeve 392.

[0048] The connecting device 395 includes a hemispherical shell 3951 , and an arc-shaped outer shell 3952 is sleeved and slidably connected to the outer side of the hemispherical shell 3951 .

[0049] The limiting device 398 includes a supporting sleeve 3981 and a sliding frame 3984. The outer side of the supporting sleeve 3981 is fixedly connected to a telescopic rod 3982. One end of the telescopic rod 3982 away from the supporting sleeve 3981 is fixedly connected to a limiting clamping plate 3983. The outer side of the sliding frame 3984 is fixedly connected to a connecting plate 3985. The inner side of the sliding frame 3984 is rotatably connected to a rolling column 3986 via a rotating bracket.

[0050] One side of the support sleeve 3981 is fixedly connected to the side of the diverter plate 33 through a bracket, and the side of the connecting plate 3985 away from the sliding frame 3984 is fixedly connected to the outer side of the vent nozzle 397, and multiple groups of rolling columns 3986 are provided.

[0051] When in use, the torsion bar is placed between the two groups of annular grinding belts 25, and the electric telescopic rod 36 is turned on to drive the tightening plate 37 to move. The two groups of tightening plates 37 can tighten the two ends of the torsion bar to clamp and fix the torsion bar. The ends of the blowing pipe 31 and the suction pipe 32 away from the diverter plate 33 are respectively connected to the external air pump, and the air is exhausted into the blowing pipe 31 through the externally connected air pump. At the same time, another group of air pumps is used to extract the air in the suction pipe 32, and the gas entering the blowing pipe 31 enters the diverter pipe 396 through the diverter plate 33. The gas entering the diverter pipe 396 passes through the arc-shaped outer shell 3952 and the hemispherical shell 3951 in turn. The gas entering the ventilation pipe 394 then passes through another group of arc-shaped outer shells 3952 and hemispherical shells 3951 in sequence and enters the ventilation nozzle 397, and is finally blown to the surface of the torsion bar through the ventilation nozzle 397. Another group of air pumps sucks the gas at the grinding position of the torsion bar from the ventilation nozzle 397 into the ventilation pipe 394, and finally enters another group of diverter plates 33 through the shunt pipe 396, and is then discharged from the diverter plate 33 through the suction pipe 32, so that the grinding position of the torsion bar can be vacuumed. The operation of using the blowing pipe 31 and the suction pipe 32 to blow air at one end of the torsion bar and suck air at the other end at the same time makes it convenient to vacuum the middle of the torsion bar, thereby improving the vacuuming efficiency.

[0052] The worker manually rotates the threaded sleeve 391, and the threaded sleeve 391 rotates on the blowing pipe 31 and the suction pipe 32, so that the threaded sleeve 391 gradually moves away from the diverter plate 33. When the threaded sleeve 391 moves, the arc rod 393 is pulled by the rotating sleeve 392, and the arc rod 393 pulls the ventilation pipe 394, so that the ventilation pipe 394 drives the hemispherical shell 3951 at one end to rotate in the arc outer shell 3952, and the other end of the ventilation pipe 394 can drive the ventilation nozzle 397 to move, so that the multiple groups of ventilation nozzles 397 are expanded outward. When the diameter of the processed torsion bar is large, the ventilation nozzle 397 can be expanded to blow and suck air on the surface of the torsion bar with a large diameter, and the position of the ventilation nozzle 397 can be adjusted to adapt to torsion bars of different diameters to maintain the dust collection efficiency on the surfaces of torsion bars of different diameters.

[0053] When the arc rod 393 pulls the ventilation tube 394, the ventilation tube 394 drives the ventilation nozzle 397 to move, and the ventilation nozzle 397 drives the sliding frame 3984 to move through the connecting plate 3985. The sliding frame 3984 slides along the limiting card plate 3983 through the rolling column 3986, and pulls the limiting card plate 3983 to move upward. When the limiting card plate 3983 moves, it drives the telescopic rod 3982 to extend. Since the limiting card plate 3983 limits the sliding frame 3984, the ventilation tube 394 can drive the ventilation nozzle 397 to keep the ventilation nozzle 397 in a horizontal state when expanding, thereby preventing the ventilation nozzle 397 from tilting and affecting the efficiency of blowing and inhaling.

[0054] Working principle: the worker puts the to-be-processed torsion bar between two groups of annular grinding belts 25, and tightens the two ends of the torsion bar through the tightening device 3, so that the torsion bar can be fixed between the two groups of annular grinding belts 25, and the electric conveying roller 24 is turned on, and the annular grinding belt 25 is driven by the electric conveying roller 24 to rotate, and the rotating annular grinding belt 25 can grind the outer surface of the torsion bar, and the annular slide rail 21 is turned on while the annular grinding belt 25 is grinding, and the annular slide rail 21 drives the electric slide rail 22 to move through the internal electric slider, and the electric slide rail 22 can drive the electric conveying roller 24 to move through the moving plate 23, and the electric conveying roller 24 drives the annular grinding belt 25 to rotate around the axis of the torsion bar, so that the outer surface of the torsion bar can be grinded in all directions. When the torsion bar to be ground has a large diameter, the electric slide rail 22 can be opened, and the electric slider inside the electric slide rail 22 can be used to drive the electric conveying roller 24 and the annular grinding belt 25 to move, so that the distance between the two sets of annular grinding belts 25 is expanded, and the torsion bar is placed between the two sets of annular grinding belts 25, and the electric telescopic rod 36 is opened to drive the tightening plate 37 to move, and the two sets of tightening plates 37 can tighten the two ends of the torsion bar to clamp and fix the torsion bar, and the ends of the blowing pipe 31 and the suction pipe 32 away from the diverter plate 33 are respectively connected to the external air pump, and the air is exhausted into the blowing pipe 31 through the externally connected air pump. At the same time, another set of air pumps is used to extract the air in the suction pipe 32, and the gas entering the blowing pipe 31 enters the diverter plate 33 into the diverter pipe 396 and enters the diverter plate The gas in the tube 396 passes through the arc-shaped shell 3952 and the hemispherical shell 3951 in turn and enters the vent pipe 394. The gas entering the vent pipe 394 then passes through another set of arc-shaped shells 3952 and hemispherical shells 3951 in turn and enters the vent nozzle 397, and is finally blown to the surface of the torsion bar through the vent nozzle 397. Another set of air pumps sucks the gas at the grinding position of the torsion bar from the vent nozzle 397 into the vent pipe 394, and finally enters another set of shunt plates 33 through the shunt pipe 396, and is then discharged from the shunt plate 33 through the suction pipe 32, so that the grinding position of the torsion bar can be vacuumed. The worker manually rotates the threaded sleeve 391, and the threaded sleeve 391 rotates on the blowing pipe 31 and the suction pipe 32, so that the threaded sleeve 391 gradually moves away from the shunt plate 33, and the threaded sleeve 391 When moving, the arc rod 393 is pulled by rotating the sleeve 392, and the arc rod 393 pulls the vent pipe 394, so that the vent pipe 394 drives the hemispherical shell 3951 at one end to rotate in the arc outer shell 3952, and the other end of the vent pipe 394 can drive the vent nozzle 397 to move, so that the multiple groups of vent nozzles 397 are expanded outward. When the diameter of the processed torsion bar is large, the surface of the torsion bar with a large diameter can be blown and inhaled by expanding the vent nozzle 397. When the arc rod 393 pulls the vent pipe 394, the vent pipe 394 drives the vent nozzle 397 to move, and the vent nozzle 397 drives the sliding frame 3984 to move through the connecting plate 3985. The sliding frame 3984 slides along the limiting card plate 3983 through the rolling column 3986, and pulls the limiting card plate 3983 to move upward.When the limit card plate 3983 moves, the telescopic rod 3982 is extended. Since the limit card plate 3983 limits the sliding frame 3984, the vent pipe 394 can drive the vent nozzle 397 to maintain the horizontal state of the vent nozzle 397 when it is extended.
