All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: a three-dimensional deviation laser measuring device of a positioning pin 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, an air cylinder 10, a reset 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 used for supporting other parts and is externally connected with the rest of the device, the detection sleeve 2 is a detection execution element which is externally output by the device, an inner hole is matched with the excircle of the measured positioning pin, the size of the inner hole is larger than the excircle limit tolerance of all the measured positioning pins, the inner chamfer angle of 30 degrees is arranged at the front end so as to lead in the measured positioning pin, the Z-direction laser reflection plate is arranged at the rear end, and a round hole is arranged in the middle and 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; after the cylinder 10 is extended, the position of the end face of the detecting sleeve 2 in a free state should exceed the limit negative deviation of the measured positioning pin in the Z direction (defining that the Z-direction plane of the measured positioning pin is a positive deviation higher than the theoretical plane and a negative deviation lower than 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, a tested device enters the checking tool, the tested device is positioned on a theoretical position of the checking tool in a mode that a positioning pin on the checking tool is inserted into a positioning sleeve on the tested device, then the air cylinder 10 moves downwards (if a plurality of devices exist, the air cylinder moves simultaneously), the sleeve 2 gradually approaches to 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 abuts against 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 a 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 gradually approaches to the position to be measured, the center of the sleeve 2 is pulled to the center of the position to be measured due to the guidance 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 position to be measured completely contacts with the inner cylindrical surface of the sleeve 2, and the end surface of the sleeve 2 abuts against the Z-direction plane of the position to be measured, so that the movement is stopped. At this time, the X-direction laser distance measuring instrument 13, the Y-direction laser distance measuring instrument 14 and the Z-direction laser distance measuring instrument 15 mounted on the cover 12 start to start at the same time, the distances to the two vertical surfaces of the guide holder 3 and the Z-direction laser reflecting plate on the sleeve 2 are measured respectively, and the reading on the laser distance measuring instrument 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.
