In this embodiment, the device mainly comprises a frame 1, a detection sleeve 2, a guide seat 3, an anti-rotation rod 4, a compression spring 5, a transition plate 6, an X-direction sliding guide rail 7, a cross-shaped support 8, a Y-direction sliding guide rail 9, a cylinder 10, a return spring 11, a cover cap 12, an X-direction laser range finder 13, a Y-direction laser range finder 14, a Z-direction laser range finder 15 and the like, wherein the frame 1 is a base of the device and is used for supporting other parts and connecting the parts to the outside, the detection sleeve 2 is a detection execution element which is output from the device to the outside, an inner hole is matched with an outer circle of a measured positioning pin, the size of the inner hole is larger than the outer circle limit tolerance of all the measured positioning pins, the front end of the detection sleeve is provided with a 30-degree inner chamfer angle so as to lead in the measured positioning pin, the rear end of the detection sleeve is provided with a Z-direction laser reflection plate, and the middle of the detection sleeve is provided with a round hole which can slide on the guide seat 3; the guide seat 3 is fixed on the transition plate 6, the base of the guide seat is rectangular, two surfaces which are vertical to each other can be used as laser reflection plates of an X-direction laser range finder 13 and a Y-direction laser range finder 14, the compression spring 5 is sleeved on the guide seat 3, the detection sleeve 2 always keeps extending downwards by thrust, the anti-rotation rod 4 is installed on the guide seat 3 to prevent the detection sleeve 2 from deflecting when sliding up and down along the guide seat 3, the transition plate 6 is fixed on a slide block of the Y-direction sliding guide rail 9, the slide block is installed on the lower surface of the cross support 8, the upper surface of the cross support 8 is connected with the slide block of the X-direction sliding guide rail 7, the slide block is fixed on a front end connecting plate of an air cylinder 10, the air cylinder 10 is of a guide rod type, the front end is downward and is vertically installed on the frame 1, the two ends of the X-direction sliding guide rail 7 and the Y-direction sliding guide rail 9 are both provided with return springs 11 to keep the slide block to tend to the middle position of the slide block, the cover 12 is fixed on the front end connection plate of the cylinder 10, and an X-direction laser distance meter 13, a Y-direction laser distance meter 14 and a Z-direction laser distance meter 15 are respectively arranged on the cover.
In the present embodiment, the cylinder of the cylinder 10 is elastically connected to the detection sleeve 2, and the moving stroke of the detection sleeve 2 on the guide seat 3 should be greater than the height of the measured positioning pin; the stroke of the cylinder 10 is equal to the sum of the measured height of the locating pin and the safety distance; when the cylinder 10 is extended, the position of the end face of the detecting sleeve 2 in a free state exceeds the limit negative deviation of the measured positioning pin in the Z direction, and the Z-direction plane of the measured positioning pin is defined as positive deviation above the theoretical plane and negative deviation below the theoretical plane. Following this principle, the device is mounted on the frame 1 of the checking tool, and if the number of the measured positioning pins is multiple, a set is mounted at each corresponding position. During operation, the tested device enters the detection tool, the tested device is positioned on the theoretical position of the detection tool in a mode that a positioning pin on the detection tool is inserted into a positioning sleeve on the tested device, then the air cylinder 10 moves downwards and acts simultaneously if a plurality of devices exist, the sleeve 2 gradually approaches the to-be-measured positioning pin, if the deviation between the center of the sleeve 2 and the center of the to-be-measured positioning pin is too large, the end face of the sleeve 2 is abutted to the upper plane of the to-be-measured positioning pin, and after the air cylinder 10 extends to the right position, the compression spring 5 is completely compressed, which is a small probability event, and indicates that the positioning system of the device is abnormally damaged. For the appliance normally in service on the production line, the deviation of the positioning system is within the detection range of the device, therefore, when the sleeve 2 approaches the measured position pin gradually, the center of the sleeve 2 is shifted to the center of the measured position pin due to the guiding of the outer chamfer of the pin and the inner chamfer of the sleeve, in the process, the movement in any horizontal direction is decomposed into the X-direction movement of the X-direction sliding guide rail 7 and the Y-direction movement of the Y-direction sliding guide rail 9 until the sleeve 2 is completely inserted into the position, namely, the outer cylindrical surface of the measured position pin is completely contacted with the inner cylindrical surface of the sleeve 2, and the end surface of the sleeve 2 is abutted against the Z-direction plane of the measured position pin, so that the movement is stopped. At this time, the X-direction laser range finder 13, the Y-direction laser range finder 14 and the Z-direction laser range finder 15 mounted on the cover 12 start to start simultaneously, and respectively measure the distances to the two vertical surfaces of the guide holder 3 and the Z-direction laser reflection plate on the sleeve 2, and the reading on the laser range finder is the deviation value. The direction and the magnitude of the deviation can be manually recorded or stored in a data processing system and automatically calculated. After the data recording is finished, the air cylinder 10 returns to the original position, and the X-direction sliding guide rail 7 and the Y-direction sliding guide rail 9 also return to the center of the sliding seat under the action of the return spring 11 to prepare for the next detection.
It should be noted that: the device needs to be provided with a three-dimensional 0-point calibration detection tool, and 0-point calibration is carried out periodically; after each detection, whether or not the X-direction slide rail 7 and the Y-direction slide rail 9 can be completely returned does not affect the next detection, and it is sufficient if the deviation of the measured positioning pin is within the detection range.
