DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a surface grinding device for automobile stamping parts, comprising a grinding frame 1 and a grinding disc 2, the grinding disc 2 is arranged in the grinding frame 1, the bottom end of the grinding frame 1 is rotatably connected with a support shaft 3, the upper end of the support shaft 3 is fixed with a support plate 4, a conical support block 5 is arranged above the support plate 4, both sides of the lower end of the conical support block 5 are fixed with L-shaped support rods 6, the bottom ends of the L-shaped support rods 6 are connected with return springs 8, the upper end of the return spring 8 is connected to the lower end of the support plate 4, the conical support block 5 and the conical pressure block 15 are symmetrically distributed up and down.

[0025] The tubular stamping part is pushed downward along the inclined surface of the conical support block 5, and the conical support block 5 will drive the L-shaped support rod 6 to stretch the return spring 8 downward, so that the tip of the conical support block 5 is inserted into the inner periphery of the lower end of the tubular stamping part, and when the tip of the conical pressing block 15 is aligned with the inner periphery of the upper end of the tubular stamping part, the L-shaped support rod 6 and the conical support block 5 are driven to move up and reset combined with the rebound force of the return spring 8. The upward movement of the conical support block 5 will push the tubular stamping part upward until the tip of the conical pressing block 15 is inserted into the inner periphery of the upper end of the tubular stamping part, so that the tubular stamping part can be conveniently pre-installed and positioned.

[0026] In this embodiment, a first lifting plate 13 is provided above the conical support block 5, a driving motor 14 is fixed to the lower end of the first lifting plate 13, a conical pressure block 15 is connected to the power end of the driving motor 14, a first lifting drive assembly is provided on the left side of the grinding frame 1, the first lifting drive assembly includes a first forward and reverse motor 10, a first screw rod 11 and a first guide rod 12, the first forward and reverse motor 10 is fixed to the top end of the grinding frame 1, one end of the first screw rod 11 is connected to the power end of the first forward and reverse motor 10, and the other end of the first screw rod 11 is rotatably connected to the bottom end of the grinding frame 1, the first lifting plate 13 is threadedly sleeved with the first screw rod 11, the first guide rod 12 is fixed to the left side of the grinding frame 1, and the first lifting plate 13 is slidably sleeved with the first guide rod 12.

[0027] Then start the first forward and reverse motor 10 to drive the first screw rod 11 to rotate, and the first screw rod 11 will drive the first lifting plate 13 to slide downward along the first guide rod 12, so the first lifting plate 13 will drive the driving motor 14 and the conical pressure block 15 to push the tubular stamping part downward, so the tubular stamping part will push the conical support block 5 and the L-shaped support rod 6 downward until the conical support block 5 is against the support plate 4. At this time, the tubular stamping part is pressed and fixed up and down, so through the cooperation of the conical support block 5 and the conical pressure block 15, tubular stamping parts of various inner diameters can be pressed and fixed up and down, and the outer surface of the tubular stamping part is completely exposed, which is conducive to ensuring the comprehensiveness of grinding and polishing.

[0028] In this embodiment, a second lifting plate 16 is provided on the right side of the grinding frame 1, and a second lifting drive assembly is provided on the right side of the grinding frame 1. The second lifting drive assembly includes a second forward and reverse motor 17, a second screw rod 18 and a second guide rod 19. The second forward and reverse motor 17 is fixed to the top of the grinding frame 1, one end of the second screw rod 18 is connected to the power end of the second forward and reverse motor 17, and the other end of the second screw rod 18 is rotatably connected to the bottom end of the grinding frame 1, the second lifting plate 16 is threadedly sleeved with the second screw rod 18, the second guide rod 19 is fixed on the right side of the grinding frame 1, the second lifting plate 16 is slidably sleeved with the second guide rod 19, and an electric cylinder 20 is fixed at the lower end of the second lifting plate 16, the power end of the electric cylinder 20 is connected to a rotating motor 26, and the grinding disc 2 is connected to the power end of the rotating motor 26.

[0029] When the tubular stamping part is being polished, the extension of the electric cylinder 20 drives the rotating motor 26 and the polishing disc 2 to approach the tubular stamping part until the polishing disc 2 can polish the tubular stamping part, and then the second forward and reverse motor 17, the rotating motor 26 and the driving motor 14 are started at the same time. When the second forward and reverse motor 17 is working, it will drive the second screw rod 18 to rotate, and the second screw rod 18 will drive the second lifting plate 16 to slide downward along the second guide rod 19. At the same time, the second lifting plate 16 will drive the electric cylinder 20, the rotating motor 26 and the polishing disc 2 to move downward together. Since the rotating motor 26 will drive the polishing disc 2 to rotate when it is working, and under the premise that the tubular stamping part is pressed up and down, the driving motor 14 will drive the conical pressing block 15, the tubular stamping part and the conical support block 5 to rotate together when it rotates, so the rotating tubular stamping part can be fully polished and polished when the polishing disc 2 moves up and down.

[0030] In this embodiment, a vacuum cleaner 21 is fixed to the upper end of the second lifting plate 16, and the suction port of the vacuum cleaner 21 is connected to a telescopic tube 23. The left end of the telescopic tube 23 is connected to an annular tube 24. The left side of the annular tube 24 is connected to a plurality of dust hoods 25. The annular tube 24 is fixedly sleeved on the outer periphery of the rotating motor 26.

[0031] During the grinding and polishing process, the vacuum cleaner 21 is started, and then the dust generated by grinding is immediately absorbed into the annular tube 24, the telescopic tube 23 and the vacuum cleaner 21 through the multiple dust hoods 25, so that the dust generated by grinding can be absorbed and processed in time, thereby reducing the pollution of the working environment by the dust and reducing the trouble of dust cleaning in the later stage. Since the electric cylinder 20 will drive the rotating motor 26 and the annular tube 24 to move together when it is extended, the annular tube 24 will stretch the telescopic tube 23, so that the dust hood 25 is always in a position close to the grinding disc 2, which is conducive to ensuring the timeliness of dust absorption and processing.

[0032] In this embodiment, the outer surfaces of the conical support block 5 and the conical pressing block 15 are both connected with anti-slip pads 9 .

[0033] By arranging anti-skid pads 9 on the outer surfaces of the conical support block 5 and the conical pressing block 15 , the anti-skid pads 9 contact the tubular stamping part, which is beneficial to increase the friction force and prevent the tubular stamping part from accidentally rotating along the conical support block 5 or the conical pressing block 15 .

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
