[0032] The present utility model provides a detection tooling for automotive parts. Figures 1 to 3 This is an embodiment of the detection tooling for automotive parts provided by the present utility model.

[0033] Please refer to Figures 1 to 3 together. The detection tooling for automotive parts includes a bottom plate 1, a plurality of support seats 7, a plurality of first clamps 8 and a plurality of simulation parts. The plurality of support seats 7 are arranged on the bottom plate 1 to support the workpiece. The plurality of first clamps 8 are arranged on the bottom plate 1 and are arranged in one-to-one correspondence with the plurality of support seats 7 to clamp and position the workpiece. The plurality of simulation parts are arranged on the bottom plate 1. Profiled areas for placing the workpiece are formed on the plurality of simulation parts. The plurality of simulation parts include a first simulation block 2, a second simulation block 3, a third simulation block 4, a fourth simulation block 5 and a fifth simulation block 6. The sides of the first simulation block 2, the second simulation block 3, the third simulation block 4, the fourth simulation block 5 and the fifth simulation block 6 facing the profiled area are fitted with the workpiece, so that the workpiece is placed on the simulation part in a fitting manner.

[0034] When the workpiece needs to be detected, first place the workpiece at the positions corresponding to the first simulation block 2, the second simulation block 3, the third simulation block 4, the fourth simulation block 5 and the fifth simulation block 6 into the profiling area, and make these corresponding positions fit with the first simulation block 2, the second simulation block 3, the third simulation block 4, the fourth simulation block 5 and the fifth simulation block 6 respectively. At the same time, the workpiece will also contact with a plurality of supporting seats 7, and the plurality of supporting seats 7 support the workpiece placed on the profiling area. Then use the first clamp 8 arranged corresponding to the supporting seat 7 to fix the workpiece so that the workpiece cannot move, ensuring that the detection result will not be deviated due to shaking during the detection. After the workpiece is fixed, use a tool for detecting the gap to measure the size of the gap between the workpiece and the simulation part, and judge whether the gap between the workpiece and the corresponding fitting during its actual assembly is qualified according to the size of the gap.

[0035] The gap between the workpiece and the simulation part is modeled after the gap between the workpiece and the fitting. Therefore, the part of the simulation part that fits with the workpiece is set according to the shape of the part where the fitting fits with the workpiece. When the workpiece is assembled on the fitting, the positions that are most likely to affect the assembly effect are generally some special-shaped surfaces, grooves or folding plates, etc. Therefore, the sides of the first simulation block 2, the second simulation block 3, the third simulation block 4, the fourth simulation block 5 and the fifth simulation block 6 facing the profiling area are designed for these positions that are most likely to affect the assembly effect to ensure that the workpiece will not be affected and cause assembly failure during the assembly process.

[0036] Therefore, in the technical solution provided by the present utility model, a plurality of the simulation parts are arranged on the bottom plate 1, and a profiling area for placing the workpiece is formed on each of the plurality of simulation parts. The plurality of simulation parts include a first simulation block 2, a second simulation block 3, a third simulation block 4, a fourth simulation block 5 and a fifth simulation block 6. The sides of the first simulation block 2, the second simulation block 3, the third simulation block 4, the fourth simulation block 5 and the fifth simulation block 6 facing the profiling area are fitted with the workpiece. By setting the sides of the simulation part facing the profiling area into a shape that fits with the workpiece, the workpiece is placed on the simulation part in a fitting manner, and it is judged whether the gap size between the workpiece and the fitting is qualified according to the gap size between the workpiece and the simulation part.

[0037] The shapes of the sides of the first simulation block 2, the second simulation block 3, the third simulation block 4, the fourth simulation block 5 and the fifth simulation block 6 facing the profiling area cannot be changed after being made. In order to be able to detect the gap between the actuator cover and its fitting, it is necessary to define the shapes of the sides of the first simulation block 2, the second simulation block 3, the third simulation block 4, the fourth simulation block 5 and the fifth simulation block 6 facing the profiling area.

[0038] Specifically, in the embodiments of the present utility model, a stepped surface that fits the workpiece is provided on the first simulation block 2, a convex block that is inserted into the groove of the workpiece is provided on the second simulation block 3, a curved surface that fits the workpiece is provided on the third simulation block 4, a boss that is inserted into the side groove of the workpiece is formed on the fourth simulation block 5, and a profiling surface that fits the folding plate of the workpiece is provided on the fifth simulation block 6.

[0039] The stepped surface on the first simulation block 2 can be mutually engaged with the bent surface at one end of the workpiece, so that the bent workpiece is mutually attached to the first simulation block 2, thereby detecting whether the gap size between the bent surface of the workpiece and the fitting is qualified. The convex block on the second simulation block 3 is used to be inserted into the groove of the other end surface of the workpiece, and the second simulation block 3 is attached to the other end surface of the workpiece, thereby detecting whether the gap size between the other end surface of the workpiece and the fitting is qualified. The curved surface on the third simulation block 4 is mutually engaged with the special-shaped surface on the side of the workpiece, thereby detecting the gap difference between the special-shaped surface on the side of the workpiece and the fitting, and can also detect in advance whether the special-shaped surface of the workpiece can be assembled into the corresponding position of the fitting. When the special-shaped surface of the workpiece cannot be attached to the third simulation block 4 when placed on the third simulation block 4, the special-shaped surface here is unqualified and cannot be assembled into the corresponding position of the fitting. The boss on the fourth simulation block 5 will be inserted into the semi-closed groove on the side of the workpiece, thereby detecting whether the groove on the side of the workpiece can be mutually engaged with the fitting, and detecting whether the size of the gap after the groove on the side of the workpiece is mutually engaged with the fitting is qualified. The several side surfaces of the fifth simulation block 6 facing the profiling area can be mutually attached to the folding plates on the side of the workpiece. There are a total of three folding plates on the side of the workpiece, and the three folding plates are perpendicular to each other. The three folding plates form a semi-closed box body. During assembly, it will enter this box body through the unclosed opening and be mutually attached to the three folding plates. By setting the fifth simulation block 6, it is detected whether the box body here can be mutually engaged with the fitting, and at the same time, the size of the gap between the box body and the fitting after engagement can also be detected.

[0040] Further, the third simulation block 4, the fourth simulation block 5 and the fifth simulation block 6 are located between the opposite sides of the first simulation block 2 and the second simulation block 3. The third simulation block 4 is located on the side of the fifth simulation block 6 facing the first simulation block 2, and the fourth simulation block 5 is located on the side of the fifth simulation block 6 facing the second simulation block 3.

[0041] The adapted shapes of different simulation blocks are different, and the positions of different shapes on the workpiece are fixed and unchanged. Since the positions of different simulation blocks set on the bottom plate 1 need to be designed according to the corresponding positions of the workpiece, the first simulation block 2 and the second simulation block 3 are respectively used to detect the clearance dimensions between the end faces of the opposite ends of the workpiece and the fitting. Therefore, the first simulation block 2 and the second simulation block 3 are correspondingly arranged with the opposite ends of the workpiece. The third simulation block 4 and the fourth simulation block 5 are respectively used to detect the non-uniform surface and the groove on the side of the workpiece, and the non-uniform surface and the groove on the side of the workpiece are both located between the opposite ends. Therefore, while the third simulation block 4 and the fourth simulation block 5 are respectively arranged at the positions corresponding to the non-uniform surface and the groove on the side of the workpiece, they are located between the opposite sides of the first simulation block 2 and the second simulation block 3. The folding plate detected by the fifth simulation block 6 is located between the non-uniform surface and the groove on the side of the workpiece. Therefore, the fifth simulation block 6 is arranged between the opposite sides of the third simulation block 4 and the fourth simulation block 5.

[0042] Furthermore, the number of the third simulation blocks 4 and the fourth simulation blocks 5 is two each, and the two third simulation blocks 4 and the two fourth simulation blocks 5 are symmetrically arranged so that the workpiece can be stably placed on the profiling area.

[0043] There are two non-uniform surfaces and two grooves on the side of the workpiece, and the two non-uniform surfaces and the two grooves are symmetrically arranged. During the production process, there will be certain differences in the dimensional sizes of different positions of the same workpiece. The two symmetrically arranged non-uniform surfaces and the two side grooves need to be detected. Therefore, the number of the third simulation blocks 4 and the fourth simulation blocks 5 is two each, and they respectively correspond to the two non-uniform surfaces and the two grooves. Therefore, the two third simulation blocks 4 and the two fourth simulation blocks 5 are also symmetrically arranged, so as to be adapted to the two non-uniform surfaces and the two grooves on the workpiece. Although there are differences between the two non-uniform surfaces and the two grooves on the workpiece, the two third simulation blocks 4 and the two fourth simulation blocks 5 used to detect the two non-uniform surfaces and the two grooves have no differences, that is, the two third simulation blocks 4 have the same size, and the two fourth simulation blocks 5 also have the same size, so as to ensure that the detected results will not be inaccurate due to the size deviation of the third simulation block 4 and the fourth simulation block 5.

[0044] The support base 7 and the first clamp 8 are arranged in cooperation with each other to fix the workpiece placed on the simulation part. To stably fix an object after it is placed, at least the two sides of the object need to be fixed. Therefore, there are at least two support bases 7, and the two support bases 7 are respectively arranged corresponding to the two sides of the workpiece. When the two support bases 7 are arranged in a staggered manner, only two non-symmetrical points on the workpiece are fixed, and the workpiece is still not stable at this time. Therefore, at least two support bases 7 are arranged symmetrically to fix the corresponding positions on the two sides of the workpiece. The positions on the workpiece that are convenient for clamping are mainly at the opposite ends of the workpiece and near the side grooves. Therefore, the support base 7 is arranged near the fourth simulation block 5 and cooperates with the first clamp 8 to fix the workpiece.

[0045] Specifically, in the embodiment of the present invention, a plurality of the support bases 7 are located between the opposite sides of the second simulation block 3 and the third simulation block 4. Two of the support bases 7 are arranged symmetrically and are arranged in one-to-one correspondence with the two fourth simulation blocks 5, so that the first clamp 8 can stably clamp and position the workpiece.

[0046] Further, a plurality of positioning seats 9 are arranged on the bottom plate 1, and positioning pins 10 are arranged on the plurality of positioning seats 9. A positioning area for placing the workpiece is formed on the positioning seat 9, and the positioning pin 10 extends towards the positioning area to limit the placement position of the workpiece when the positioning pin 10 penetrates the workpiece located in the positioning area.

[0047] When the workpiece is placed on the simulation part, it is not restricted yet. The user judges whether the workpiece is placed in the appropriate position through visual inspection. Visual inspection has certain limitations. At the same time, because the workpiece is not restricted, the workpiece is extremely easy to be affected by external forces and shift before being fixed by the first clamp 8. Therefore, the workpiece needs to be restricted when placed on the simulation part to avoid shifting before being fixed. While the positioning pins 10 on the plurality of positioning seats 9 limit the placement position of the workpiece, it also makes it impossible for the workpiece to shift before being fixed after the positioning pins 10 penetrate the plurality of holes on the workpiece, thereby ensuring the accuracy of the workpiece during the inspection after installation. A single positioning pin 10 can only limit the general placement position of the workpiece. Therefore, a plurality of positioning pins 10 are provided. The cooperation of the plurality of positioning pins 10 limits the placement position of the workpiece and also makes it impossible for the workpiece to move towards the outer peripheral side after being placed, so as to ensure that the position of the workpiece will not shift.

[0048] The position of the fourth simulation block 5 is biased towards the second simulation block 3, and the support base 7 is arranged near the fourth simulation block 5. As a result, one end of the workpiece corresponding to the first simulation block 2 near the workpiece is not fixed, which may cause this end of the workpiece to warp during fixation, leading to an increase in the gap between the first simulation block 2 and the workpiece. Therefore, a second clamp 13 is provided at the position corresponding to the first simulation block 2. By clamping and fixing one end of the workpiece that fits the first simulation block 2 with the second clamp 13, this end of the workpiece cannot warp. After the workpiece is placed on the simulation part and the positioning pin 10 passes through the through hole on the workpiece, the first clamp 8 and the second clamp 13 are used to clamp and fix the workpiece for the detection work.

[0049] Specifically, in the embodiment of the present invention, the second clamp 13 is provided on the base plate 1, and the second clamp 13 is arranged corresponding to the first simulation block 2. The second clamp 13 is used for clamping and positioning the workpiece.

[0050] There are many tools that can detect the gap between the workpiece and the simulation part. One of the most convenient detection tools is the feeler gauge 11. The feeler gauge 11 is composed of measuring rods or needles with different thicknesses. The end of the measuring rod or needle used to insert into the gap to be measured is usually made into spherical, pointed or flat shapes, etc., so as to adapt to different positions or different shapes of the gaps to be measured. By inserting the measuring rods or needles with different thicknesses into the gap to be detected and judging whether the size of the measured gap is qualified according to the maximum thickness of the measuring rod or two needles inserted into the gap.

[0051] Specifically, in the embodiment of the present invention, the feeler gauge 11 is provided on the base plate 1 to detect the gap between the workpiece and the simulation part when the feeler gauge 11 is inserted between the workpiece and the simulation part.

[0052] There is a groove on the opposite surface of the workpiece that fits the third simulation block 4. At this time, the groove does not fit the third simulation block 4. Therefore, a device for detecting this groove is arranged near the third simulation block 4 to detect the surface difference of the workpiece here.

[0053] Specifically, in the embodiment of the present invention, the detection component 12 is provided on the base plate 1 to detect the surface difference of the workpiece when the detection component 12 moves.

[0054] Further, the detection component 12 includes a fixed seat 121 and a flush block 123. The fixed seat 121 is disposed on the bottom plate 1. A movable rod 122 is slidably connected to the fixed seat 121, and the movable rod 122 moves toward or away from the workpiece. The flush block 123 is disposed on one side of the movable rod 122 facing the third simulation portion. The flush block 123 is in contact with the third simulation portion, and the flush block 123 is slidably connected in the arc-shaped groove of the workpiece. When the feeler gauge 11 is inserted between the flush block 123 and the workpiece, the gap between the flush block 123 and the workpiece is detected.

[0055] When detecting the surface difference of the groove on the special-shaped surface of the workpiece, move the movable rod 122, drive the flush block 123 to move together through the movable rod 122 until the flush block 123 enters the corresponding groove on the third simulation block 4. Then place and fix the workpiece to ensure that the workpiece is completely in contact with the flush block 123. Then insert the feeler gauge 11 between the flush block 123 and the workpiece. If the feeler gauge 11 cannot be inserted between the flush block 123 and the workpiece, it means that the groove size on the special-shaped surface of the workpiece is completely qualified, and there is no depression or unevenness on the inner cavity surface of the groove here. If the feeler gauge 11 can be inserted between the flush block 123 and the workpiece, continuously replace feeler gauges 11 with different thicknesses and insert them into the gap between the workpiece and the flush block 123, so as to detect the size of the gap, record it, and then compare the recorded result with the specified size to ensure that the workpiece can be normally assembled.

[0056] There are multiple gaps to be detected on the entire actuator cover, and the specified size of each gap is different. However, the difference between each gap and the specified size is required to be within 0.3 millimeters. If the difference exceeds 0.3 millimeters, it is an unqualified size. A too small size means that there is still excess material on the workpiece that has not been cleaned up, and the size can be made to meet the standard through secondary processing. While a workpiece with a too large size cannot have the corresponding size made to meet the standard through secondary processing and can only be recycled and remanufactured.

[0057] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
