Most body components are stamping parts with extremely irregular shapes. Before the welded parts are matched and assembled, each part must be inspected. Only when they meet the relevant size and technical requirements can they be assembled and welded. The edge contour of some workpieces is inspected by profiling and making special inspection fixtures, and the matching surfaces are inspected by three-coordinate measurement to see if their shape and position tolerances meet the requirements.

At the same time, since a positioning plate 11 is provided on the top of the fixed seat 2, and the top of the fixed seat 2 is set at an inclined angle, when the inner square frame of the sheet metal 3 is hung on the outside of the top of the fixed seat 2, due to the height difference between the positioning plate 11 and the fixed seat 2, the sheet metal 3 will slide down automatically due to its gravity. At this time, the sheet metal 3 will be hung on the top of the fixed seat 2, thereby enabling the sheet metal to be placed on the top of the fixed seat 2, and also facilitates the positioning of the sheet metal by the later positioning component and the clamping component.

[0024] like Figures 1 to 4As shown, two slide rails 13 are fixedly connected to the top of the top plate 5, and the top of the slide rail 13 is slidably connected with a moving seat 6. The bottom of the mounting seat 7 is fixed at an inclined angle and is fixed to the top of the moving seat 6. The inclined angle of the mounting seat 7 is adapted to the inclined angle of one side of the top of the sheet metal part 3. A positioning plate 11 is fixedly connected to the outside of the top of the fixed seat 2. The specifications and dimensions of the positioning plate 11 are adapted to the specifications and dimensions of the internal frame shape of the sheet metal part 3.

A probe is installed at one end of the detection rod 10. The input end of the detection box 8 is electrically connected to the output end of the probe. The specifications and dimensions of one side of the detection box 8 are adapted to the specifications and dimensions of one side of the top of the sheet metal part 3. By setting the mounting seat 7 to be connected to the moving seat 6 at an inclined angle, the detection box 8 on one side of the mounting seat 7 is adapted to the angle of one side of the top of the sheet metal part 3, thereby promoting The top side of the sheet metal 3 can be fitted to one side of the detection box 8, so as to facilitate the detection of the sheet metal by the probe at one end of the detection rod 10. At the same time, since a positioning plate 11 is provided on the top of the fixing seat 2, and the top of the fixing seat 2 is set at an inclined angle, the fixing seat 2 can fix the position of the bottom of the sheet metal 3 from the inside of the sheet metal 3, so as to facilitate the positioning of the sheet metal 3 by the later positioning component and the clamping component. First, when fixing the sheet metal 3, the square frame in the middle of the sheet metal 3 is placed on the top of the positioning plate 11. At this time, by setting the positioning plate 11 to match the size of the square frame inside the sheet metal 3 and setting the top of the fixing seat 2 at an inclined angle, the sheet metal 3 is hung on the top of the positioning plate 11 by automatic gravity. At the same time, by setting a height difference between the positioning plate 11 and the fixing seat 2, the problem of the sheet metal 3 falling off from the top of the fixing seat 2 is avoided. At the same time, by setting the detection rod 10 to be threadedly connected with the adjusting rod 9, it is convenient to perform probe detection of different points on the sheet metal by replacing different detection rods 10 in the later stage.

[0025] like Figures 1 to 7As shown, the positioning assembly includes a positioning block 16 fixedly connected to the inside of the base 1, a plurality of arc grooves 17 are opened at equal distances on the top of the positioning block 16, two pulleys 19 are slidably connected to the top of the arc groove 17, a telescopic rod 20 is installed on the top of the two pulleys 19, a fixed cylinder 21 is slidably connected to the top of the telescopic rod 20, a first spring is fixedly connected inside the fixed cylinder 21, one end of the first spring is fixedly connected to the top of the telescopic rod 20, a connecting plate 24 is fixedly connected to the opposite side of the two fixed cylinders 21, a connecting rod 15 is fixedly connected to one side of the connecting plate 24, and the connecting rod 15 is away from the connecting rod 15. One end of the connecting plate 24 is fixedly connected to the arc plate 14, and the material of the arc plate 14 is rubber. Two slide grooves 12 are provided on the top of the top plate 5, and a moving groove 22 is provided inside the slide groove 12. A moving plate 23 is slidably connected inside the moving groove 22.

When the movable seat 6 is pushed to one side of the sheet 3 during use When the top of the curved plate 14 is completely pressed against the bottom of the sheet 3, the pulley 19 just moves into the inside of the curved groove 17. At this time, it is only necessary to insert the positioning rod 26 into the slot 18 to complete the accurate fixation of the position of the detection box 8, thereby avoiding the problem of low detection degree caused by inaccurate positioning in the traditional method. When the sheet 3 is placed on the top of the fixed seat 2, the positioning rod 26 is moved by moving the movable seat 6 to drive the linkage cylinder 25 to move with the fixed cylinder 21. At the same time, the curved plate 14 at one end of the connecting rod 15 will continue to approach At the bottom of the sheet 3, the pulley 19 will move on the top of the positioning block 16. At the same time, when the pulley 19 moves to the top of the positioning block 16, the telescopic rod 20 will shrink into the inside of the fixed cylinder 21, and squeeze the first spring inside the fixed cylinder 21 to shrink.

At this time, the length of one side of the sheet 3 may be longer or shorter. At this time, through the multiple arc grooves 17, the pulley 19 is moved to the multiple arc grooves 17 to fix the position of the movable seat 6, which facilitates the detection of the detection box 8. ;

By setting the slot 18, the positioning spring 27, the stop bolt 28 and the limit block 30, in order to increase the detection accuracy of the detection box 8 In order to improve the accuracy and avoid the problem of movement of the movable seat 6 during detection, when the pulley 19 moves to the inside of the arc groove 17, the stop bolt 28 is rotated to prompt the fixed plate 29 to move away from the top of the limit block 30. At this time, the positioning spring 27 will automatically rebound, prompting the positioning spring 27 to move downward with the stop bolt 28, and then prompting the bottom end of the positioning rod 26 to be inserted into the inside of the slot 18, thereby prompting the position of the movable seat 6 to be stably fixed. At the same time, after the later detection, when moving the movable seat 6, first pull the stop bolt 28 upward to prompt the bottom end of the positioning rod 26 to move away from the inside of the slot 18, and at the same time rotate the positioning rod 26 to prompt the fixed plate 29 to move and rotate to the top of the limit block 30.

At the same time, one side of the sheet metal part 3 will contact one end of the movable rod 38, prompting one side of the top of the sheet metal part 3 to squeeze one end of the movable rod 38 to move toward one side of the fixed block 34, and at the same time, the movable block 47 will move with the second connecting plate 41 and the first connecting plate 40, and at the same time, the fourth connecting plate 43 at one end of the two third connecting plates 42 will continue to approach each other. At this time, when the position of the movable seat 6 is fixed, the hexagonal clamp 44 at one end of the fourth connecting plate 43 will contact one side of the top of the sheet metal part 3, and at the same time, the two hexagonal clamps 44 will clamp one side of the top of the sheet metal part 3. At this time, the bolt 4 at the top of one end of the movable rod 38 just moves to the bottom of the limiting cylinder 49. At this time, through the positioning hole and the second spring, At this time, the second spring automatically pushes the bolt 4 to rebound into the positioning hole, thereby causing the position of the movable rod 38 to be fixed, thereby preventing the hexagonal clamp 44 from clamping the sheet metal part 3, thereby facilitating the detection of the sheet metal part 3. At the same time, by setting the second knob 36 and the first knob 33, when the sheet metal part 3 is produced in the later stage, the sheet metal part 3 will have errors and different curvatures. At this time, the height and angle of the fixed block 34 can be adjusted by the second knob 36 and the screw on one side of the first knob 33. When adjusting, slide the slip ring to adjust the height of the fixed block 34, and then rotate the first knob 33 to cause the screw at one end of the first knob 33 to contact one side of the fixed rod 31, thereby causing the fixed block The height of the fixing block 34 is fixed. When adjusting the angle of the fixing block 34, the fixing block 34 is rotated to rotate outside the fixing shaft. At this time, the second knob 36 is rotated to cause the screw to continuously move toward one end of the fixing shaft. At this time, when one side of the second knob 36 is attached to one side of the fixing block 34, the angle of the fixing block 34 is fixed. At the same time, the return bolt 35 is set. When the clamping and fixing of the sheet metal 3 is released later, the return bolt 35 is pressed to cause the bottom end of the return bolt 35 to press against the top of the clamping bolt 4. At this time, the rebound spring 48 automatically rebounds, causing the clamping bolt 4 to move away from the positioning hole, thereby causing the two hexagonal clips 44 to move away from each other, thereby releasing the clamping and fixing of the sheet metal 3. ;

[0028] like Figures 8 to 10As shown, the six faces of the hexagonal clamp 44 are respectively fixedly connected with an arc block, a conical block, an anti-sliding block, a rubber block, a wave block and a multi-column block, the multi-column block is composed of a plurality of circular columns, one side of one end of the fourth connecting plate 43 is rotatably connected with a rotating shaft, the outside of the rotating shaft is fixedly connected to the inside of the middle part of the hexagonal clamp 44, the other side of the fourth connecting plate 43 is rotatably connected with a third knob 45, one side of the third knob 45 is fixedly connected with a threaded rod, one end of the threaded rod passes through the inside of the fourth connecting plate 43 and is connected with the internal thread at one end of the rotating shaft; by setting the six faces of the hexagonal clamp 44 to be an arc block, a conical block, an anti-sliding block, a rubber block, a wave block and a multi-column block respectively, the irregular shape of the outside of the sheet metal part 3 can be clamped, the arc design can better fit the shape of the sheet metal part 3, especially its irregular curved surface part, thereby reducing the pressure concentration during clamping and reducing the possibility of dents, and the design of the conical block helps to clamp the dents on the outside of the sheet metal part 3, thereby prompting the hexagonal clamp 44 to fit the outside of the sheet metal part 3 more closely. The dent and anti-sliding block has a rough surface, which can increase the friction between the sheet member 3 and the rubber block, which has good elasticity and shock absorption performance, can buffer the impact force during the clamping process and reduce the generation of dents. The design of the wave block can increase the contact area with the sheet member 3, make the pressure distribution more uniform, and reduce the generation of dents. The multi-column block is composed of multiple circular columns. This design can further disperse the pressure, make the pressure distribution more uniform, reduce the risk of dents, and thus facilitate the clamping of the sheet member 3. When in use, the hexagonal clamp 44 can be rotated to cause the different clamps on the outside of the hexagonal clamp 44 to correspond to the different materials and traces on the outside of the sheet member 3. At the same time, when the position of the hexagonal clamp 44 is adjusted, the third knob 45 is rotated to cause the threaded rod on one side of the third knob 45 to continuously move toward the inside of the rotating shaft. When one side of the third knob 45 is attached to one side of the fourth connecting plate 43, the position of the hexagonal clamp 44 is fixed, thereby facilitating the use of the hexagonal clamp 44.
