Description
Technical Field
[0001] This utility model relates to the field of automotive parts inspection tools, specifically a left door sill inner panel inspection tool with a fixed function. Background Technology
[0002] With the development of the automotive industry, people's demand for automotive quality is getting higher and higher. After the automotive parts are manufactured, they need to be inspected for shape and size using inspection tools, especially for assembly performance, such as whether they can be welded and assembled with other designed parts, or how accurate the assembly parts are after welding and assembly. Therefore, data inspection of automotive parts is particularly important.
[0003] In existing technologies, when using a gauge to inspect the inner left sill plate, there is usually a movable component with holes for insertion as needed. The inspector inserts a dial indicator into the hole, presses it down so that the measuring end of the dial indicator is against the testing surface of the inner left sill plate, and then moves the movable component to observe the dial indicator reading. When using this method to inspect the inner left sill plate, the inspector needs to hold the dial indicator down continuously. However, different inspectors apply different pressures to the dial indicator. If the pressure is too light, the measuring end of the dial indicator may not be in contact with the testing surface of the inner left sill plate; if the pressure is too heavy, the dial indicator may be damaged. This leads to inaccurate test data. Furthermore, the position of the holes on the movable component is fixed, and the inspector cannot flexibly adjust the position of the dial indicator to achieve range-based testing. All of these factors may affect the pass rate of the final assembly after the automotive parts are welded. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a left sill inner panel inspection tool with a fixing function, including an adjustable height support body and an inspection tool body. The inspection tool body is provided with a fixing mechanism 9 for pressing and fixing the left sill inner panel 5 and a detection mechanism 7 that can move laterally to detect the deformation deviation value of the left sill inner panel 5. After the left sill inner panel 5 placed on the inspection tool body is fixed by the fixing mechanism 9, the left sill inner panel 5 is detected by driving the detection mechanism 7 to move.
[0025] The support body includes a base frame 1 and a support frame 2 that can move up and down on the base frame 1. A lifting mechanism 10 is provided between the base frame 1 and the support frame 2. By driving the lifting mechanism 10, the support frame 2 can move up and down along the base frame 1, and the support height of the support frame 2 can be adjusted. Universal wheels 14 are fixedly installed at the four corners of the bottom of the base frame 1.
[0026] The lifting mechanism 10 includes support rods 101. Support rods 101 are rotatably connected to the four corners of the base frame 1. Connecting blocks 102 are rotatably connected to one end of each of the four support rods 101. Two horizontally corresponding connecting blocks 102 are threaded with bidirectional lead screws 103. The bidirectional lead screws 103 are rotatably connected to the support frame 2. The connecting blocks 102 are slidably connected to the bottom of the support frame 2. Guide slide rods 13 are fixedly connected to the support frame 2 and are slidably connected to the base frame 1. Pulleys 104 are fixedly connected to the two bidirectional lead screws 103. Transmission belts 105 are fitted onto the two pulleys 104, allowing the transmission belts 105 to drive... Two pulleys 104 are connected by a drive mechanism. One end of a double-acting screw 103 passes through the inside of the support frame 2 and is fixedly connected to a turntable 106. By holding the turntable 106, one of the double-acting screws 103 can be rotated, causing the corresponding pulley 104 to drive the other pulley 104 to rotate via the drive belt 105. As a result, the other double-acting screw 103 will rotate synchronously. Simultaneously, the two connecting blocks 102 on the same double-acting screw 103 will move closer or further apart, while pushing the support frame 2 to drive the guide slide rod 13 to slide in the base frame 1, causing the support frame 2 and the base frame 1 to move closer or further apart.
[0027] The inspection fixture includes a support base 3, on which a mold base 4 is provided for positioning and supporting the inner panel 5 of the left sill. The mold base 4 has multiple positioning holes to facilitate the positioning and placement of the inner panel 5 of the left sill. The support base 3 is provided with a guide rail 6, on which a guide slide block 25 is slidably provided. A support block is provided on the guide slide block 25. The inspection mechanism 7 is provided on the support block. The inspection mechanism 7 is provided with a dial indicator 8 for detecting the flatness of the inner panel 5 of the left sill. By driving the guide slide block 25 to slide left and right along the guide rail 6, the inspection mechanism 7 can drive the dial indicator 8 to slide, thereby detecting the inner panel 5 of the left sill through the value detected by the dial indicator 8.
[0028] There are two guide rails 6, which are distributed on the top two sides of the support base 3, and each support base 3 is equipped with a detection mechanism 7.
[0029] The testing mechanism 7 includes a movable component 71, which is fixedly connected to a support block. The movable component 71 has a sliding groove 72, and a fixed component 73 is slidably connected inside the sliding groove 72. The fixed component 73 has an installation cavity 15 inside, and a fixed clamping piece 16 is provided in the installation cavity 15. A threaded rod 17 is rotatably connected to the fixed clamping piece 16, and the threaded rod 17 is threadedly connected to the fixed component 73. The dial indicator 8 can be inserted into the installation cavity 15, and the fixed clamping piece 16 clamps the dial indicator 8 by twisting the threaded rod 17.
[0030] The slide groove 72 has a guide groove 77 on one side, and the guide groove 77 is through. The moving part 71 is fixedly connected to the edge of the guide groove 77 with an anti-slip pad 18. The slide groove 72 has a positioning groove 76 on the other side, with two positioning grooves 76 distributed vertically. The fixing part 73 is fixedly connected to two positioning blocks 75 that slide in cooperation with the positioning grooves 76, and a screw 74 that slides in cooperation with the guide groove 77. The screw 74 is threaded with a fixing nut 78. When the fixing part 73 is pushed to slide in the slide groove 72, the screw 74 will slide in the guide groove 77, and the two positioning blocks 75 will slide in the corresponding positioning grooves 76, while limiting the fixing part 73 to prevent it from rotating. When the fixing part 73 moves to the appropriate position, the fixing nut 78 can be tightened to make the fixing nut 78 stick tightly to the anti-slip pad 18, thereby fixing the fixing part 73.
[0031] The movable part 71 has a dovetail groove 19, and an insert block 20 is provided in the dovetail groove 19. A ball block 21 is fixedly connected to the top of the insert block 20.
[0032] It is worth mentioning that the two moving parts 71 can be connected together by inserting the plug 20 into the corresponding dovetail groove 19, so that the two moving parts 71 can slide synchronously for detection.
[0033] The support block is slidably connected to a pull rod 22. A limit rod 23 is fixedly connected to the outside of the pull rod 22 above the support block. The support block is provided with a limit groove for limiting the limit rod 23. A limit ring is fixedly connected to the outside of the pull rod 22 below the support block. A spring 24 is sleeved on the outside of the pull rod 22 between the limit ring and the support block. The support base 3 is provided with a socket 26 for the spring 24 to be inserted. When the detection mechanism 7 is not in use, the guide slide 25 can slide to both ends of the guide slide rail 6. At this time, the limit ring will drive the pull rod 22 to be stably inserted into the socket 26 under the elastic force of the spring 24. The limit rod 23 will be inserted into the limit groove to fix the detection mechanism 7. When the detection mechanism 7 is in use and moving, the pull rod 22 can be pulled upward to make the limit rod 23 disengage from the limit groove and rotate the pull rod 22 90° so that the pull rod 22 rests on the support block and disengages from the socket 26.
[0034] Among them, the top of the support base 3 and the two ends of the guide slide rail 6 are fixedly connected to the mounting base 11, and the mounting base 11 is equipped with anti-collision rods 12 that can buffer the detection mechanism 7.
[0035] The fixing mechanism 9 includes a fixing seat 91. The fixing seat 91 is installed on the top of the support seat 3. A connector 93 is provided on the top of the fixing seat 91. A wrench 92 and a fixing rod 94 are provided on the connector 93. The wrench 92 can drive the fixing rod 94 to tighten or loosen the inner panel 5 of the left door sill through the connector 93.
[0036] It is worth mentioning that multiple sets of fixing mechanisms 9 can be set, so that multiple sets of fixing mechanisms 9 can press the inner plate 5 of the left sill from different positions.
[0037] The specific working principle is as follows: Before the inspection, the operator can adjust the height of the support body according to the height of the site and their own height, so that the operator can carry out the inspection in a comfortable posture.
[0038] First, by rotating the turntable 106, one of the double-acting lead screws 103 is driven to rotate. Under the action of the two pulleys 104 and the transmission belt 105, the double-acting lead screw 103 will drive the other double-acting lead screw 103 to rotate synchronously. As a result, the two connecting blocks 102 on the same double-acting lead screw 103 will slide close to or separate from each other along the bottom of the support frame 2, causing the support rod 101 to rotate around the base frame 1, thereby pulling the support frame 2 downward or pushing the support frame 2 upward, and adjusting the support height of the support frame 2.
[0039] After adjustment, the left sill inner panel body 5 to be tested can be placed on the mold base 4. The left sill inner panel body 5 is positioned by the cooperation of the positioning hole and the positioning pin. Then, the left sill inner panel body 5 is pressed by the fixing mechanism 9. First, by turning the wrench 92, the wrench 92 drives the connecting piece 93 to move, thereby driving the fixing rod 94 to press the left sill inner panel body 5. Next, the fixing nut 78 needs to be loosened so that the fixing piece 73 slides in the slide groove 72 to the corresponding testing position. Then, the fixing nut 78 can be tightened to fix the fixing piece 73. Then, the dial indicator 8 is pulled out to adjust the position of the dial indicator 8 in the mounting cavity 15 so that the dial indicator 8 can detect... The probe can contact the main body 5 of the left sill inner panel. Then, twist the threaded rod 17 to clamp the dial indicator 8 with the fixing clip 16 and fix the dial indicator 8. At this time, pull the pull rod 22 upward to disengage the pull rod 22 from the insertion hole 26 and release the detection mechanism 7 from the fixed state. Then, by moving the guide slide 25, the moving part 71 moves laterally on the support base 3 with the dial indicator 8 to detect the main body 5 of the left sill inner panel. When the moving part 71 moves to the fixing pressure rod 94, the wrench 92 needs to be held to open the fixing pressure rod 94 so that the moving part 71 can pass through and then press the main body 5 of the left sill inner panel. The moving part 71 continues to detect the main body 5 of the left sill inner panel with the dial indicator 8.
[0040] When simultaneous testing of both sides is required, the operator can pinch the ball block 21 and insert the insert block 20 into the dovetail groove 19, so that the two moving parts 71 are connected together and move synchronously.
[0041] It is worth mentioning that: pressing the workpiece with the fixing mechanism 9 is a common practice in the field of the art, and its structural principle will not be described in detail.
