Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: a rapid detection device for the hole position deviation of automobile parts, including a positioning post 2, a carrier table 4 arranged on the positioning post 2, and a measuring device fixing seat 5 arranged on the carrier table 4. A measuring mechanism 1 for detecting the transverse deviation and longitudinal deviation is arranged on the carrier table 4;

[0025] The measuring mechanism 1 includes a mounting platform 106, the mounting platform 106 is arranged on the carrier table 4, a positioning platform 105 is arranged on the upper side of the mounting platform 106, the mounting platform 106 is connected to the carrier table 4 through a transverse moving structure, the positioning platform 105 is connected to the mounting platform 106 through a longitudinal moving structure, a positioning sleeve 102 is arranged on the positioning platform 105, and a positioning pin 103 is arranged in the positioning sleeve 102.

[0026] The lateral movement mechanism includes a lateral lead screw 108 which is rotatably arranged in a lateral sliding groove 109. The lateral lead screw 108 is also connected to a first motor 101 on one side of the carrier 4. The lateral sliding groove 109 is arranged on the carrier 4. A first nut 107 is also arranged on the lateral lead screw 108. The first nut 107 is connected to the mounting table 106, capable of adjusting the lateral position of the mounting table 106 and measuring the lateral deviation of the hole position.

[0027] First, install four groups of dial indicators in the fixed seat 5 of the measuring device respectively. Then, make the dial indicators fit with the positioning table 105 and zero the dial indicators. Next, fix the positioning post 2 in the preset hole position of the inspection tool. Then, drive the lateral lead screw 108 to rotate in the lateral sliding groove 109 by the first motor 101. The first nut 107 drives the mounting table 106 to move laterally. The mounting table 106 drives the positioning table 105 to move laterally. The positioning table 105 drives the positioning pin 103 to move. When the positioning table 105 moves and presses the dial indicator, when the positioning pin 103 moves into the hole position of the automotive part, the lateral deviation of the hole position can be measured through the difference value of the dial indicator.

[0028] The longitudinal movement structure includes a longitudinal lead screw 110 which is rotatably arranged in a longitudinal sliding groove 112. The longitudinal lead screw 110 is connected to a second motor 113 on the mounting table 106. The longitudinal sliding groove 112 is arranged on the mounting table 106. A second nut 111 is also arranged on the longitudinal lead screw 110. The second nut 111 is connected to the positioning table 105, capable of adjusting the longitudinal position of the positioning table 105 and measuring the longitudinal deviation of the hole position.

[0029] Drive the longitudinal lead screw 110 to rotate in the longitudinal sliding groove 112 by the second motor 113. The second nut 111 drives the positioning table 105 to move longitudinally. The positioning table 105 moves longitudinally and presses the longitudinally arranged dial indicator. The movement of the positioning table 105 drives the positioning pin 103 to move. When the positioning pin 103 is inserted into the hole position of the automotive part, the longitudinal deviation of the hole position of the automotive part can be measured through the value of the longitudinally arranged dial indicator.

[0030] Furthermore, a first spring 104 is also arranged in the positioning sleeve 102. The first spring 104 is connected to the positioning pin 103. When the positioning table 105 drives the positioning sleeve 102 to move, the positioning pin 103 compresses the second spring 35. When the positioning pin 103 moves to the hole position on the automotive part, under the action of the elastic force, the first spring 104 snaps the positioning pin 103 into the hole on the automotive part, automatically positioning the positioning pin 103 into the hole position of the automotive part.

[0031] As a specific embodiment of this application, please refer to Figure 5, a plurality of automatic fixing mechanisms 3 are annularly arranged on the positioning post 2. Specifically, the number of automatic fixing mechanisms 3 can be 3 groups, 4 groups, 5 groups, etc. The automatic fixing mechanism 3 includes a fixing pin 34, and the fixing pin 34 is movably arranged in the receiving groove 33.

The second spring 35 is connected to the fixing pin 34 and can quickly fix the positioning post 2 in the preset hole position of the fixture.

[0032] During installation, the positioning post 2 is inserted into the preset hole position on the spacing. During the insertion process of the positioning post 2, the fixing pin 34 moves in the receiving groove 33 and compresses the second spring 35. When the positioning post 2 is completely snapped into the preset hole position, the second spring 35 makes the fixing pin 34 fit with the preset hole position and fixes the positioning post 2 in the preset hole position.

[0033] Furthermore, an inclined guiding surface is arranged on one side of the fixing pin 34 to facilitate guiding the fixing pin 34 into the preset hole position.

[0034] Furthermore, guiding sliders 32 are arranged on both sides of the fixing pin 34. One end of the guiding slider 32 is slidably arranged in the guiding chute 31. The guiding chute 31 is arranged on both side surfaces in the receiving groove 33. The movement of the fixing pin 34 drives the guiding slider 32 to move in the guiding chute 31, improving the guiding property when the fixing pin 34 moves.

[0035] An installation groove is arranged on the measuring device fixing seat 5, and a locking bolt for fixing the dial indicator is also arranged on the measuring device fixing seat 5, which can quickly fix the dial indicator.

[0036] In this application, the first motor 101 and the second motor 113 can be connected to an external control switch through a wireless or wired connection method.
