Description

Technical Field

[0001] This utility model relates to the field of automotive parts inspection, and in particular to a device for detecting hole position deviation dimensions of automotive parts. Background Technology

[0002] In the automotive manufacturing industry, the precision of automotive parts directly determines the safety and assembly reliability of the entire vehicle. This is especially true for the connecting holes on both sides of automotive parts, which are core force transmission nodes for body structural components (such as the subframe, etc.). When the connecting holes are properly aligned, the vehicle load should be evenly distributed along the designed path. If the connecting holes are misaligned, the preload distribution of the bolts on the automotive parts becomes unbalanced. This can lead to minor issues like loose bolt connections causing abnormal noises, or more serious issues like stress concentration points shifting, affecting the collision energy transmission path and posing a significant safety hazard.

[0003] Currently, the connection holes on both sides of automotive parts are mainly measured manually using vernier calipers. However, due to the large number of automotive parts to be measured in each batch, operators are prone to visual bias under high-intensity work conditions, causing inconvenience in the inspection of automotive parts. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a hole position deviation detection device for automobile parts. The purpose is to solve the technical problem that the connection holes on both sides of automobile parts are mainly measured manually using vernier calipers, which involves high measurement intensity.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A device for detecting hole position deviation of automotive parts includes a worktable and a movable seat. A rotating shaft is rotatably connected to the top of the worktable. A first sliding groove is formed inside the movable seat, and the rotating shaft slides into the first sliding groove. Clamping extension seats are provided on both sides of the movable seat. A clamping surface is provided on the top of the worktable, and the clamping surface is spaced apart from any of the clamping extension seats to form a clamping interval. The automotive part is located within the clamping interval. Detection seats are provided on both sides of the top of the clamping surface. Multiple detection moving frames are provided inside the detection moving frames. A second sliding groove is formed inside the detection moving frames, and a movable rod is slidably connected inside the second sliding groove. One end of the movable rod is provided with a detection insertion rod, which is inserted into an adjacent connection hole.

[0007] When the first sliding groove of the movable seat slides upward along the rotation axis, the car part is placed on the clamping surface of the worktable. As the operator rotates the movable seat, the movable seat rotates through the rotation axis, so that any clamping extension seat corresponds to the clamping surface. At this time, the car part is located within the clamping interval. The first sliding groove of the movable seat slides downward along the rotation axis, so that any clamping extension seat clamps the car part within the clamping interval. During inspection, the operator pushes the movable rod along the second sliding groove towards the car part. The detection probe fixed at the end of the movable rod is then inserted into the connection hole where the car part should be. If the position of the connection hole is accurately machined, the detection probe can be smoothly and completely inserted into the connection hole without obstruction. If the position of the connection hole is offset, the detection probe cannot be completely inserted into the hole, and the position of the connection hole of the car part is unqualified. Thus, the operator can determine whether the hole is qualified by the insertion of the detection probe, replacing the traditional method of relying entirely on human eyes to observe the vernier caliper reading, improving the accuracy and efficiency of the inspection.

[0008] Furthermore, in this application, a movable groove is provided on one side of the detection seat, and the detection movable frame slides in cooperation with the adjacent movable groove. Guide sliders are provided at both ends of the detection movable frame, and guide grooves are provided on both sides of the movable groove. The guide sliders at both ends of the detection movable frame slide in cooperation with the guide grooves on both sides of the movable groove. A connecting groove communicating with the movable groove is provided on the other side of the detection seat. The size of the connecting groove is smaller than that of the movable groove, so that the other end of the movable rod passes through the connecting groove. A fixed base is provided on one side of the detection seat. The fixed base is located below the movable groove. A fixed plate is movably connected to the top of the fixed base. One side of the detection movable frame protrudes out of the movable groove, and one side of the fixed plate abuts against the bottom of one side of the detection movable frame.

[0009] Multiple inspection moving frames can be slidably connected to the movable slots, so that when the batch of automotive parts changes, the position of their connection holes will also change. By changing the position of the inspection moving frames, one side of the fixed plate abuts against the bottom of one side of the inspection moving frame to fix the adjusted position of the inspection moving frames, thereby adapting to the connection hole position of the new batch of automotive parts. The other side of the inspection seat is provided with a connecting slide groove to allow the longer movable rod to have sufficient room to move. When the connection hole of the automotive part is deep, in order to accurately determine whether the bottom position of the connection hole is qualified, the inspection rod needs to be able to penetrate to the bottom of the hole. When the longer movable rod slides in along the second sliding groove, the inspection rod can be inserted into the bottom of the connection hole with sufficient length due to the increase in the length of the movable rod, thereby improving the accuracy of the inspection.

[0010] Furthermore, in this application, the fixed base frame has a first screw-in hole inside, and a fixed screw is threaded into the first screw-in hole. The other side of the fixed plate has a first rotating groove, and a stabilizing bearing is provided in the first rotating groove. One end of the fixed screw is rotatably connected to the stabilizing bearing.

[0011] When the fixing screw is rotated using a wrench (or other tool), due to the action of the threaded joint, the fixing screw will produce a vertical linear motion. Clockwise rotation causes the fixing screw to rotate upward and lift; conversely, clockwise rotation causes the fixing screw to descend. After the position of the moving frame is adjusted, the fixing screw drives the fixing plate to contact the moving frame, thus facilitating the fixing of the moving frame after its movement. At the same time, one end of the fixing screw is rotatably connected to the stabilizing bearing, so that during the rotation of the fixing bolt, the rotational motion of the fixing screw is isolated by the stabilizing bearing, and only a non-rotating vertical lifting force is applied to the fixing plate, so that the fixing plate will not be dragged laterally or shaken due to the rotation of the fixing screw during the lifting process.

[0012] Furthermore, in this application, the fixed base frame has multiple guide grooves inside, and the other side of the fixed plate has multiple guide slide rods, with the multiple guide slide rods slidingly engaging with the multiple guide grooves respectively.

[0013] Furthermore, in this application, a row of fixing teeth is formed on one bottom side of the detection moving frame, and a plurality of fixing grooves are formed on one side of the fixing plate, wherein the fixing teeth are inserted into the adjacent fixing grooves.

[0016] Furthermore, in this application, a fixing hole communicating with the second screw-in hole is provided on one side of the support frame, and a fixing bolt is threaded into the fixing hole, the fixing bolt abutting against the lifting slide rod.

[0017] Furthermore, in this application, the bottom of the movable seat is provided with a plurality of first mounting posts, the bottom of the first mounting posts is provided with limiting inserts, the top of the worktable is provided with a plurality of second mounting posts, the top of the second mounting posts is provided with limiting slots, and the limiting inserts are inserted into the adjacent limiting slots.

[0018] Furthermore, in this application, the bottom of each of the two clamping extension seats is provided with a first mounting seat, and any one of the first mounting seats can be alternately located inside the clamping interval. The bottom of the first mounting seat has a first mounting cavity, and a first positioning plate is inserted into the first mounting cavity. The bottom of the first positioning plate has multiple first positioning pins, which are used to engage with the top holes of the automotive parts. The sides of the first mounting seat have first locking holes communicating with the first mounting cavity, and the sides of the first positioning plate have second locking holes. A first locking bolt passes through the first locking hole, and the first locking bolt engages with the adjacent... The second locking hole is threadedly engaged. A second mounting seat is provided on the top of the clamping surface. The second mounting seat is located inside the clamping interval. A second mounting cavity is opened on the top of the second mounting seat. A second positioning plate is inserted into the second mounting cavity. A plurality of second positioning pins are provided on the top of the second positioning plate. The second positioning pins are used to insert into the bottom holes of the automotive parts. A third locking hole communicating with the second mounting cavity is opened on both sides of the second mounting seat. A fourth locking hole is opened on both sides of the second positioning plate.

[0036] Reference Figures 1-10 In some specific embodiments, a hole position deviation size detection device for automotive parts includes a worktable 1 and a movable seat 2. A rotating shaft 8 is rotatably connected to the top of the worktable 1. A first sliding groove 6 is provided inside the movable seat 2, and the rotating shaft 8 slides in cooperation with the first sliding groove 6. Clamping extension seats 3 are provided on both sides of the movable seat 2. A clamping surface 4 is provided on the top of the worktable 1. The clamping surface 4 and any clamping extension seat 3 are separated to form a clamping interval 5. The automotive part is located within the clamping interval 5. Detection seats 35 are provided on both sides of the top of the clamping surface 4. Multiple detection moving frames 38 are provided inside the detection moving frames 35. A second sliding groove 44 is provided inside the detection moving frames 38. A movable rod 39 is slidably connected inside the second sliding groove 44. A detection insertion rod 40 is provided at one end of the movable rod 39, so that the detection insertion rod 40 is inserted into the adjacent connection hole.

[0037] With the above technical solution, when the first sliding groove 6 of the movable seat 2 slides upward along the rotating shaft 8, the car part is placed on the clamping surface 4 of the worktable 1. As the operator rotates the movable seat 2, the movable seat 2 rotates via the rotating shaft 8, so that any clamping extension seat 3 corresponds to the clamping surface 4. At this time, the car part is located within the clamping interval 5. The first sliding groove 6 of the movable seat 2 slides downward along the rotating shaft 8, so that any clamping extension seat 3 and the clamping surface 4 clamp the car part within the clamping interval 5. During inspection, the operator pushes the movable rod 39 along the second sliding groove 44. When the automotive part slides, the detection rod 40, fixed at the end of the movable rod 39, is inserted into the connection hole where the automotive part should be located. If the connection hole is machined precisely, the detection rod 40 can be smoothly and completely inserted into the connection hole without obstruction. If the connection hole is offset, the detection rod 40 cannot be completely inserted into the hole, and the connection hole position of the automotive part is unqualified. Thus, the operator can determine whether the hole is qualified by observing the insertion of the detection rod 40, which replaces the traditional method of relying entirely on human eyes to observe the vernier caliper reading, improving the accuracy and efficiency of the inspection.

[0038] It should be noted that the preset positions of the detection rods 40 of the multiple detection moving frames 38 are the corresponding positions of the connection holes of standard automotive parts, so that after the automotive parts are placed within the clamping interval 5, it can be judged whether they are qualified by whether the detection rods 40 can be inserted into the connection holes.

[0039] In addition, it should be noted that the bottom of the clamping extension seat 3 is usually matched with the shape of the car part, so that when the car part is clamped by the clamping extension seat 3 and the clamping surface 4, the clamping extension seat 3 can provide sufficient contact area for the car part, making the car part more stable when clamped; while the movable seat 2 is provided with clamping extension seats 3 on both sides, the purpose of which is to accommodate the clamping of two car parts with different top surface shapes, while the other parts of the car part have the same shape, so as to improve the clamping efficiency of the car part.

[0040] Reference Figures 6-10In some specific embodiments, a movable groove 36 is provided on one side of the detection seat 35, and the detection moving frame 38 slides in cooperation with the adjacent movable groove 36. Guide sliders 43 are provided at both ends of the detection moving frame 38, and guide slide grooves 37 are provided on both sides of the movable groove 36. The guide sliders 43 at both ends of the detection moving frame 38 slide in cooperation with the guide slide grooves 37 on both sides of the movable groove 36, respectively. A connecting slide groove 56 is provided on the other side of the detection seat 35, which is smaller than the movable groove 36, so that the other end of the movable rod 39 passes through the connecting slide groove 56. A fixed base frame 46 is provided on one side of the detection seat 35. The fixed base frame 46 is located below the movable groove 36. A fixed plate 47 is movably connected to the top of the fixed base frame 46. One side of the detection moving frame 38 protrudes out of the movable groove 36, and one side of the fixed plate 47 abuts against the bottom of one side of the detection moving frame 38.

[0041] Through the above technical solution, multiple inspection moving frames 38 can be slidably connected to the movable groove 36, so that when the batch of automotive parts changes, the position of their connection holes will also change. By changing the position of the inspection moving frame 38, one side of the fixed plate 47 abuts against the bottom of one side of the inspection moving frame 38 to fix the adjusted position of the inspection moving frame 38, thereby adapting to the connection hole position of the new batch of automotive parts. The other side of the inspection seat 35 is provided with a connecting groove 56 to allow the longer movable rod 39 to have enough room to move. When the connection hole of the automotive part is deep, in order to accurately determine whether the bottom position of the connection hole is qualified, the inspection rod 40 needs to be able to penetrate to the bottom of the hole. When the longer movable rod 39 slides in along the second sliding groove 44, the inspection rod 40 can be inserted into the bottom of the connection hole with sufficient length due to the increased length of the movable rod 39, thereby improving the accuracy of the inspection.

[0042] In addition, the movable position of the inspection frame 38 can be confirmed by external calipers, or a scale can be set on one side of the inspection seat 35 to make it easy to observe the adjustment position of the inspection frame 38.

[0043] Reference Figures 6-10 In some specific embodiments, a first screw-in hole 52 is provided inside the fixed base frame 46, and a fixed screw 53 is threadedly connected to the first screw-in hole 52. A first rotating groove 51 is provided on the other side of the fixed plate 47, and a stabilizing bearing 54 is provided in the first rotating groove 51. One end of the fixed screw 53 is rotatably connected to the stabilizing bearing 54.

[0044] With the above technical solution, when the fixing screw 53 is rotated using a wrench (or other tool), the fixing screw 53 will generate a vertical linear motion. Clockwise rotation causes the fixing screw 53 to rotate upward and lift; conversely, clockwise rotation causes the fixing screw 53 to descend. After the detection moving frame 38 is adjusted, the fixing screw 53 drives the fixing plate 47 to abut against the detection moving frame 38, thereby facilitating the fixing of the position of the detection moving frame 38 after movement. At the same time, one end of the fixing screw 53 is rotatably connected to the stabilizing bearing 54, so that during the rotation of the fixing bolt 59, the rotational motion of the fixing screw 53 is isolated by the stabilizing bearing 54, and only a non-rotating vertical lifting force is applied to the fixing plate 47, so that the fixing plate 47 will not be dragged laterally or shaken due to the rotation of the fixing screw 53 during the lifting process.

[0045] In addition, one end of the fixing screw 53 is a smooth surface, thereby increasing the contact area between the fixing screw 53 and the stabilizing bearing 54.

[0046] Reference Figures 6-10 In some specific embodiments, the fixed base frame 46 has multiple guide grooves 49 inside, and the other side of the fixed plate 47 has multiple guide slide rods 50, which slide in cooperation with the multiple guide grooves 49 respectively.

[0047] With the above technical solution, when the fixed plate 47 is lifted by the screw, multiple guide slide rods 50 slide in cooperation with multiple guide grooves 49 respectively. Even if the lifting force has a slight deviation on the point of action of the fixed plate 47, the uniformly distributed constraint of multiple guide slide rods 50 and multiple guide grooves 49 can automatically correct the posture and ensure the stability of the fixed plate 47 when it is raised and lowered.

[0048] Reference Figures 6-10 In some specific embodiments, a row of fixing teeth 45 is formed on one side bottom of the detection moving frame 38, and a plurality of fixing grooves 48 are formed on one side of the fixing plate 47, with the fixing teeth 45 being inserted into the adjacent fixing grooves 48.

[0049] With the above technical solution, when one side of the fixing plate 47 abuts against the bottom of one side of the detection moving frame 38, the fixing tooth 45 is inserted into the adjacent fixing tooth groove 48, thereby preventing the detection moving frame 38 from shifting under external vibration and improving the stability of the position of the detection moving frame 38.

[0050] Reference Figures 6-10In some specific embodiments, one end of the movable rod 39 is provided with a first limiting plate 41, which is close to the clamping interval 5. The size of the first limiting plate 41 is larger than the size of the second sliding groove 44. The detection insertion rod 40 is provided on one side of the first limiting plate 41. The other end of the movable rod 39 is provided with a second limiting plate 55. A return spring 42 is sleeved on the outside of the movable rod 39. One end of the return spring 42 abuts against the second limiting plate 55, and the other end of the return spring 42 abuts against the other side of the detection moving frame 38.

[0051] With the above technical solution, when the car part is clamped in the clamping interval 5, the operator pushes the movable rod 39 to move, so that the movable rod 39 drives the detection rod 40 to insert into the connection hole of the car part. At this time, since one end of the return spring 42 is in contact with the second limit plate 55 and the other end of the return spring 42 is in contact with the other side of the detection moving frame 38, the return spring 42 will retract under the action of the movable rod 39. When the operator releases the force applied to the movable rod 39, the return spring 42 will extend, thereby driving the second limit plate 55 to move. This causes the second limit plate 55 to drive the movable rod 39 away from the car part, and the detection rod 40 disengages from the connection hole under the action of the movable rod 39. This prevents the operator from forgetting to reset the detection rod 40 after the inspection. If the operator forgets to reset and directly removes the car part, it will cause damage to the detection rod 40 and the connection hole.

[0052] Reference Figures 1-5 In some specific embodiments, the outer edge of the rotating shaft 8 is provided with multiple movable sliders 9, the interior of the first sliding groove 6 is provided with multiple movable sliding grooves 7, the multiple movable sliders 9 are respectively slidably engaged with the multiple movable sliding grooves 7, the exterior of the rotating shaft 8 is provided with two limiting blocks 10, the movable seat 2 is located between the limiting blocks 10, the top of the movable seat 2 is provided with a support frame 13, the interior of the support frame 13 is provided with a connecting cavity 57 communicating with the first sliding groove 6, the top of the support frame 13 is provided with a second screw-in hole 14 communicating with the connecting cavity 57, the interior of the second screw-in hole 14 is threadedly connected with a lifting slide rod 15, one end of the lifting slide rod 15 is provided with a lifting block 16, the lifting block 16 is located in the connecting cavity 57, one end of the rotating shaft 8 passes through the connecting cavity 57, so that the lifting block 16 abuts against the rotating shaft 8, the top of the worktable 1 is provided with a second rotating groove 11, the interior of the second rotating groove 11 is provided with a rotating bearing 12, the other end of the rotating shaft 8 is rotatably engaged with the inner ring of the rotating bearing 12.

[0053] With the above technical solution, when the lifting slide rod 15 is screwed into the second screw-in hole 14, the lifting block 16 of the lifting slide rod 15 will abut against the top of the rotating shaft 8. As the lifting slide rod 15 is screwed in, the movable seat 2 will be lifted. The first sliding groove 6 will slide along the rotating shaft 8. Multiple movable sliders 9 will slide and cooperate with multiple movable grooves 7 respectively, so as to guide the sliding position of the movable seat 2, so that the movable seat 2 will drive the clamping extension seat 3 away from the worktable 1. At the same time, when the rotating shaft 8 rotates, since the movable slider 9 is located in the movable groove 7, the rotating shaft 8 can drive the movable seat 2 to rotate synchronously, so as to drive the clamping extension seat 3 to rotate to the clamping surface 4.

[0054] Reference Figures 1-5 In some specific embodiments, a fixing hole 58 communicating with the second screw-in hole 14 is provided on one side of the support frame 13. A fixing bolt 59 is threaded into the fixing hole 58, and the fixing bolt 59 abuts against the lifting slide rod 15.

[0055] With the above technical solution, when the car part is placed in the clamping interval 5, the lifting slide rod 15 is rotated out of the second screw-in hole 14, so that the movable seat 2 drives the clamping extension seat 3 to approach the car part, the fixing bolt 59 is screwed into the fixing hole 58, and the fixing bolt 59 abuts against the lifting slide rod 15 so that the sliding position of the movable seat 2 is fixed, thereby clamping the car part.

[0056] Reference Figures 1-5 In some specific embodiments, the bottom of the movable seat 2 is provided with a plurality of first mounting posts 17, the bottom of the first mounting posts 17 is provided with a limiting insertion post 18, the top of the worktable 1 is provided with a plurality of second mounting posts 19, the top of the second mounting posts 19 is provided with a limiting slot 20, and the limiting insertion post 18 is inserted into the adjacent limiting slot 20.

[0057] With the above technical solution, when the car part is placed in the clamping interval 5, the lifting slide 15 rotates out of the second screw-in hole 14, so that the movable seat 2 drives the clamping extension seat 3 to approach the car part. At this time, the limiting plug 18 is inserted into the adjacent limiting slot 20, thereby restricting the rotation of the movable seat 2 and preventing the movable seat 2 from rotating when the car part is clamped.

[0058] Reference Figures 1-5In some specific embodiments, the bottom of the two clamping extension seats 3 is provided with a first mounting seat 21. Either first mounting seat 21 can be alternately located inside the clamping interval 5. The bottom of the first mounting seat 21 has a first mounting cavity 22. A first positioning plate 23 is inserted into the first mounting cavity 22. The bottom of the first positioning plate 23 has multiple first positioning posts 24, which are used to insert into the top holes of the automotive parts. The first mounting seat 21 has first locking holes 25 on both sides communicating with the first mounting cavity 22. The first positioning plate 23 has second locking holes 27 on both sides. A first locking bolt 26 passes through the first locking hole 25 and is engaged with the adjacent... The second locking hole 27 is threadedly engaged. The top of the clamping surface 4 is provided with a second mounting seat 28, which is located inside the clamping interval 5. The top of the second mounting seat 28 is provided with a second mounting cavity 29, and a second positioning plate 30 is inserted into the second mounting cavity 29. The top of the second positioning plate 30 is provided with a plurality of second positioning pins 31, which are used to be inserted into the bottom holes of the automotive parts. The two sides of the second mounting seat 28 are provided with third locking holes 33 that communicate with the second mounting cavity 29. The two sides of the second positioning plate 30 are provided with fourth locking holes 32. A second locking bolt 34 passes through the third locking hole 33 and is threadedly engaged with the adjacent fourth locking hole 32.

[0059] With the above technical solution, when the car part is placed in the clamping interval 5, the multiple first positioning pins 24 at the bottom of the first positioning plate 23 will be inserted into the holes at the top of the car part, and the second positioning pins 31 at the top of the second positioning plate 30 will be inserted into the holes at the bottom of the car part, thereby facilitating the limiting of the placement position of the car part. If the batch of car parts changes, the positions of the holes at the top and bottom of the car part will also change. At this time, the first positioning plate 23 can be disengaged from the first mounting cavity 22 and the second positioning plate 30 can be disengaged from the second mounting cavity 29 by unscrewing the first locking bolt 26 and the second locking bolt 34, so as to facilitate the replacement of the first positioning plate 23 and the second positioning plate 30 to adapt to the hole positions of the new car part (the positions of the first positioning pins 24 and the second positioning pins 31 will correspond to the holes of the new car part).

[0060] It should be noted that the holes on the top and bottom of automotive parts are decorative holes for appearance and are not bolt connection holes. Therefore, the precision of the holes on the top and bottom of automotive parts does not need to be strictly controlled during production.
