DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the utility model provides a technical solution: a finishing equipment for a cylinder body, comprising a base 1 and a workpiece body 3, the upper top of the base 1 is symmetrically fixedly connected with a side plate 11, the upper top of the side plate 11 is fixedly connected with a top plate 12, the outer side wall of the top plate 12 is fixedly connected with an L-shaped plate 13, the workpiece body 3 is arranged at the upper top of the base 1, the outer side wall of the workpiece body 3 is provided with a piston hole 31 that cooperates with the piston, limited position feet 32 ​​are arranged at the four corners of the upper top of the workpiece body 3, the lower bottom end of the L-shaped plate 13 is provided with a grinding component for processing the inside of the piston hole 31, so as to remove burrs and other impurities inside the piston hole 31, and the lower bottom end of the L-shaped plate 13 is provided with a driving structure for driving the grinding component to move.

[0030] like Figure 1 , Figure 2 and Figure 5 As shown, the driving structure includes a first hydraulic push rod 4 slidably connected to the inner bottom end of the L-shaped plate 13, the outer wall of the first hydraulic push rod 4 is fixedly sleeved with a fixed sleeve 41, the inner side wall of the L-shaped plate 13 is fixedly connected with a second hydraulic push rod 42, the telescopic end of the second hydraulic push rod 42 is fixedly connected to the outer wall of the fixed sleeve 41, the telescopic end of the first hydraulic push rod 4 is fixedly connected with a connecting plate 43, the connecting plate 43 and the grinding assembly can be driven to move horizontally and vertically through the telescopic ends of the two hydraulic push rods, so as to better perform processing operations, and the grinding assembly is arranged at the lower bottom end of the connecting plate 43.

[0031] like Figure 5 and Figure 6 As shown, the grinding assembly includes an internal support structure, a grinding part and a separation structure that match the internal size of the piston hole 31. The separation structure includes a servo motor 5 fixedly connected to the lower bottom end of the connecting plate 43. The output end of the servo motor 5 is fixedly connected to a driving rod 51. The outer wall of the driving rod 51 is slidably connected to a second chuck 53. The second chuck 53 moves linearly on the outer wall of the driving rod 51, but when the driving rod 51 rotates, it can also drive the second chuck 53 to rotate. The outer wall of the driving rod 51 is located on one side of the second chuck 53 and is rotatably connected to a first chuck 52. The end of the first chuck 52 is fixedly connected to a three-claw clamping plate 55. The separation structure also includes a sleeve 6 rotatably connected to the outer wall of the driving rod 51. The end of the sleeve 6 is fixedly connected to a third chuck 54 that is clamped with the second chuck 53. The outer wall of the sleeve 6 is provided with a thread.

[0032] like Figure 1 and Figure 2 As shown, the internal support structure includes a connecting sleeve 61 arranged on the outer wall of the sleeve 6, and the inner wall end of the connecting sleeve 61 is rotatably connected with a threaded sleeve 64 and a bearing 65 symmetrical to the threaded sleeve 64. When the connecting sleeve 61 moves through the threaded sleeve 64, the bearing 65 will pull the connecting sleeve 61 to move linearly. The bearing 65 is rotatably connected to the sleeve 6, and a plurality of fixed plates 66 are arranged in a circular array on the outer wall of the connecting sleeve 61. The outer wall of the connecting sleeve 61 and the lower bottom end of the fixed plate 66 are fixedly connected with a plurality of fixed brackets 62, and the inner side walls of every two fixed brackets 62 are rotatably connected with a connecting rod 63. The end of the fixed plate 66 is slidably connected to the inside of the three-claw clamping plate 55. By squeezing the three-claw clamping plate 55 by the fixed plate 66, the fixed plate 66 can be made to move linearly upward, so as to realize the internal support operation of the piston hole 31. The grinding part includes a grinding cam 67 fixedly connected to the outer side wall of the fixed plate 66.

[0033] like Figure 1 and Figure 3As shown, the upper top of the top plate 12 is fixedly connected to a plurality of cylinders 2, the telescopic end of the cylinder 2 is fixedly connected to a gas rod 21 for applying pressure to the limit foot 32, the upper top of the base 1 is fixedly connected to a plurality of fixed seats 22, the upper top of the fixed seat 22 is symmetrically fixedly connected to a top seat 23 in contact with the lower bottom end of the workpiece body 3, and the upper top of the base 1 is symmetrically fixedly connected to a turntable 24 on one side of the fixed seat 22.

[0034] Working principle: When in use, the bottom surface of the workpiece body 3 is brought into contact with the top seat 23 set on the top of the fixed seat 22 through the lifting machine, and then in order to stabilize it, the multiple cylinders 2 set on the top of the top plate 12 can be started. At this time, the telescopic end of the cylinder 2 drives the gas rod 21 to contact with the piston hole 31 at the top of the workpiece body 3, thereby realizing the limitation of the workpiece body 3, and then the inside of the piston hole 31 can be polished. The telescopic end of the second hydraulic push rod 42 pushes the fixed sleeve 41 and the first hydraulic push rod 4 to move. In this process, in order to ensure the stable movement of the first hydraulic push rod 4, the top of the first hydraulic push rod 4 is slidably connected with the inner top of the L-shaped plate 13. Then, when the first hydraulic push rod 4 moves to the corresponding position, the telescopic end of the first hydraulic push rod 4 will drive the connecting plate 43 to move downward, so that the center of the grinding assembly is aligned with the center of the piston hole 31. First, it is necessary to adjust the internal support structure according to the internal size of the piston hole 31, and move the second chuck manually. 53, so that the second chuck 53 is clamped with the third chuck 54, and in this process, bolts are needed to be tightened, and then the servo motor 5 drives the driving rod 51 and the second chuck 53 to rotate, and the second chuck 53 drives the third chuck 54 and the sleeve 6 to rotate. When the sleeve 6 rotates, the threaded sleeve 64 will move on the outer wall of the sleeve 6, thereby driving the connecting sleeve 61 to move. Since the end of the bearing 65 is located inside the three-claw clamping plate 55, at this time, with the cooperation of the fixed bracket 62 and the connecting rod 63, the fixing plate 66 and the grinding cam 67 can be expanded outward. When the grinding cam 67 contacts the inner wall of the piston hole 31, the second chuck 53 is disconnected from the third chuck 54 and connected to the first chuck 52. When the driving rod 51 rotates again, driven by the second chuck 53 and the first chuck 52, the three-claw clamping plate 55 will drive the fixing plate 66 to rotate, thereby realizing that the grinding cam 67 grinds the inside of the piston hole 31.

[0035] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
