DETAILED DESCRIPTION

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0022] Secondly, the present invention is described in detail with reference to the schematic diagram.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Figure 1-Figure 3 The utility model shows a schematic diagram of the entire structure of a rotary compressor crankshaft processing device, please refer to Figure 1-Figure 3A rotary compressor crankshaft processing device according to the present embodiment includes a vertical rust removal box 10, wherein the lower end of the rust removal box 10 is provided with a lower clamping assembly 20 mounted on one end of the crankshaft, and the upper end of the rust removal box 10 is provided with an upper clamping assembly 30 mounted on the other end of the crankshaft, and the upper clamping assembly 30 is driven to rotate horizontally by a driving device; an electric slide rail 40 is arranged on one side of the rust removal box 10 along its height direction, and a slide seat 401 is arranged on the electric slide rail 40, and a sandblasting adjustment assembly 50 is arranged on one side of the slide seat 401; wherein, the longitudinally mounted crankshaft is driven to rotate horizontally by the lower clamping assembly 20 and the upper clamping assembly 30, and the sandblasting adjustment assembly 50 is driven to move up and down by the slide seat 401, and the rotating crankshaft is sandblasted and rust-removed in the height direction and the circumferential direction.

[0025] It can be understood that the rust removal box 10 is also provided with a box door 101 on the front, and the box door 101 is also equipped with a visual window. Here, when the rust removal box 10 is operating normally, its box door 101 is in a closed state to prevent waste chips from splashing and noise from leaking out. At the same time, the staff can observe the rust removal processing of the crankshaft in the box through the visual window.

[0026] In this embodiment, the lower clamping assembly 20 includes a rotating shaft 201 installed at the bottom of the inner cavity of the rust removal box 10, and an axis end clamp 202 rotatably installed at the upper end of the rotating shaft 201; the upper clamping assembly 30 includes a turntable 301 rotatably installed at the top of the inner cavity of the rust removal box 10, an electric rod 302 vertically installed at the bottom of the turntable 301, an axis end clamp 2 303 installed at the output end of the bottom of the electric rod 1 302, and a servo motor 304 installed at the upper end of the rust removal box 10 and with the output shaft end fixedly connected to the axis center of the turntable 301. Here, the axis end clamp 202 and the axis end clamp 2 303 can clamp and position the two axis ends of the crankshaft. The structure and style of the body are not limited to the examples in the pictures given in this embodiment, and can be clamped manually, electrically or pneumatically, etc.; in actual use, the lower shaft end of the crankshaft can be fixed in the shaft end clamp 202, and then the electric rod 302 is started according to the specific length of the crankshaft to drive the shaft end clamp 203 to descend until the shaft end clamp 203 can clamp the upper shaft end of the crankshaft. When sandblasting, the servo motor 304 can drive the two clamps and the crankshaft to rotate longitudinally in cooperation with the turntable 301 and the rotating shaft 201, so as to facilitate the spray gun 503 to perform circumferential sandblasting and rust removal on the crankshaft, and play the role of automatic flipping and conversion, which is simple to operate and practical.

[0027] In this embodiment, the sandblasting adjustment component 50 includes an electric push rod 501 horizontally installed on the outside of the slide 401, a mounting plate 502 vertically installed on the output end of the electric push rod 501, an ear plate 504 fixed to the outside of the mounting plate 502, a spray gun 503 installed on the inner side of the ear plate 504 through the rotation of the shaft, and a motor 505 installed on the outside of the ear plate 504 and driving the axial rotation of the shaft. During operation, the spray gun 503 is driven to move laterally by the electric push rod 501, so that the spray gun 503 can be adjusted in distance according to the actual diameter size and structure of the crankshaft, which is conducive to the smooth rust removal. At the same time, since the corner surfaces of the crankshaft are mostly vertically corresponding, in order to facilitate the sandblasting direction to better act on the rust removal surface, the motor 505 drives the spray gun 503 to swing up and down, so that the spray gun 503 can effectively sandblast and rust remove the corner surfaces of the crankshaft, and the rust removal effect is simple and reasonable.

[0028] Furthermore, the sandblasting adjustment component 50 also includes a crankshaft scanning component 506 which is arranged on the mounting plate 502 and on the same side as the spray gun 503; the main control center of the processing device, namely the controller 60, is also arranged on the outside of the rust removal box 10. Here, it can be understood that the crankshaft scanning component 506 can adopt an ultrasonic scanner, which can transmit the feedback information of the sound wave to the controller 60, and obtain the specific contour of the crankshaft and the distance from the spray gun 503 through system analysis, and generate a three-dimensional contour map of the crankshaft through the control end. In this way, the electric slide rail 40, the sandblasting adjustment component 50 and the clamping adjustment component can be adjusted according to the matching control of the control end to achieve the purpose of all-round sandblasting and rust removal of the crankshaft.

[0029] Furthermore, a hollow mesh plate 70 is provided at the bottom of the inner cavity of the rust removal box 10, and a storage box 701 which can be pulled out of the rust removal box 10 is provided at the lower end of the hollow mesh plate 70. When sandblasting and rust removal are performed, a large amount of sand and rust will be generated in the rust removal box 10. These sand and rust can fall directly into the storage box 701 through the hollow mesh plate 70, so that the storage box 701 can be taken out for processing later.

[0030] In summary, a rotary compressor crankshaft processing device according to the present embodiment can, when in use, clamp and position the upper and lower shaft ends of the crankshaft through shaft end clamp 1 202 and shaft end clamp 2 303, and then close the box door 101. When sandblasting, the servo motor 304 can drive the two clamps and the crankshaft to rotate longitudinally and axially with the cooperation of the turntable 301 and the rotating shaft 201, so as to facilitate the spray gun 503 to perform circumferential sandblasting and rust removal on the crankshaft. At the same time, the spray gun 503 is driven to move laterally by the electric push rod 2 501, so that the spray gun 503 can adjust the distance according to the actual diameter size and structure of the crankshaft, which is conducive to the good rust removal. At the same time, since the corner surfaces of the crankshaft are mostly vertically corresponding, in order to facilitate the spray direction of the sandblasting to better act on the rust removal surface, the motor 505 drives the spray gun 503 to swing up and down, so that the spray gun 503 can effectively sandblast and rust remove the corner surfaces of the crankshaft.

[0031] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
