[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model embodiment discloses an auxiliary positioning device for processing a housing of an automobile air compressor.

[0028] The utility model provides Figure 1-4 An auxiliary positioning device for processing an automobile air compressor housing shown in the figure comprises a base 1 and a cross bar 2 rotatably arranged on the upper ends of both sides of the base 1, a positioning ring 3 is fixedly arranged between the two cross bars 2, annular grooves 4 are provided on both sides of the outer wall of the positioning ring 3, two symmetrically arranged sliding sleeves 5 are slidingly sleeved on the outer sides of the two annular grooves 4, the sliding sleeves 5 are arranged in a "concave" shape, a positioning frame 6 is fixedly arranged between the two sliding sleeves 5, an electric cylinder 7 is fixedly arranged on the outer wall of the positioning frame 6, and a pressure plate 8 is fixedly arranged at the end of the piston rod of the electric cylinder 7.

[0029] Before processing the air compressor housing, place the housing in the positioning frame 6, and then start the electric cylinder 7 to move the pressure plate 8. Through the cooperation between the pressure plate 8 and the inner wall of the positioning frame 6, the air compressor housing can be stably squeezed in the positioning frame 6, and the initial processing position of the positioning frame 6 is determined. Through the rotation between the cross bar 2 and the base 1, and the sliding cooperation between the sleeve 5 and the annular groove 4, the clamped housing can be adjusted for processing angles and flipped, so that the operator does not need to move around the housing to quickly process various parts of the outer side of the housing, thereby improving the processing efficiency and operating convenience of the air compressor housing.

[0030] In order to be able to quickly flip and adjust the angle of the air compressor shell according to the required processing parts after the initial clamping of the shell, such as Figure 1-3 As shown, a flip positioning mechanism is provided between the crossbar 2 and the base 1, and the rotation transposition mechanism includes a connecting plate 9, which is fixedly connected to the sliding sleeve 5, and a positioning rod 10 is slidably penetrated inside, and a first spring 11 is provided on the rod wall of the positioning rod 10, and the two ends of the first spring 11 are respectively fixedly connected to the connecting plate 9 and the positioning rod 10, and a plurality of positioning holes for plugging in the positioning rod 10 are provided on the outer side of the positioning ring 3, and the plurality of positioning holes are symmetrically arranged around the center of the positioning ring 3;

[0031] A rotational transposition mechanism is provided between the upper sliding sleeve 5 and the positioning ring 3. The flip positioning mechanism includes an outer gear ring 12, which is sleeved on the outer side of the cross bar 2 through a sliding limit mechanism. The sliding limit mechanism includes a slide rod 14, which is fixed inside the outer gear ring 12. A slide groove is provided on the rod wall of the cross bar 2. The end of the slide rod 14 is slidably arranged in the slide groove and is fixedly connected to the inner wall of the slide groove through a second spring 15. An inner gear ring 13 is fixedly provided on the outer side of the base 1. The inner gear ring 13 is sleeved on the outer side of the cross bar 2 and meshed with the outer gear ring 12.

[0032] When the back side of the housing needs to be processed, the outer gear ring 12 can be pulled first, so that the outer gear ring 12 is pulled out from the inner gear ring 13 under the sliding cooperation of the slide rod 14 and the slide groove. At this time, the cross bar 2 can drive the positioning ring 3 to rotate under the support of the base 1. During the rotation of the positioning ring 3, the clamped air compressor housing can be turned over, and its back side can be exposed in front of the operator for processing;

[0033] When it is necessary to process other parts of the shell at different angles, the positioning rod 10 can be pulled out from the positioning hole at the current position, and the connecting plate 9 can be pulled to allow the inner shell of the positioning frame 6 to rotate in the sliding cooperation between the sleeve 5 and the annular groove 4, so as to adjust the positioning angle of the air compressor shell, facilitate convenient and effective processing of various parts on the outside of the shell, and improve the processing efficiency of the air compressor shell.
