[0001] This utility model relates to the field of testing tooling, specifically a testing tool for the back cover of an automotive seat headrest. Background Technology
[0002] The structure of the car seat headrest cover is a cover shape with a snap fastener on the inner wall. To ensure the accurate assembly of the snap fastener with other car seat components, the snap fastener end face needs to be inspected to promptly screen out products with uneven snap fastener end faces. Existing inspection tools do not include the function of inspecting the snap fasteners of this type of product. For example, Chinese patent CN223564932U discloses a car rear headrest cover inspection device, including a frame, a mounting plate, an annular frame, a wedge block, a support column, several fasteners set on the mounting plate, a positioning column set on the mounting plate and located within the annular frame, a gap detection component detachably set on the mounting plate, and a quick-locking mechanism set on the mounting plate and located outside the annular frame, corresponding one-to-one with the positioning column. The quick-locking mechanism is located below the annular frame, and there is a gap between the rear headrest cover and the annular frame after installation. The quick-locking mechanism includes a fixing block set on the mounting plate on the frame, a quick clamp set on the fixing block, and a pressure head driven by the quick clamp. The back cover of the cited patent is similar to the headrest cover structure of this application. However, the cited patent can only detect the outer edge of this application and cannot detect the inverted end face inside this application.
[0003] Therefore, it is necessary to provide a tooling for inspecting the back cover of a car seat headrest. Utility Model Content
[0004] This utility model provides an inspection tool for the back cover of an automotive seat headrest, which effectively solves the problem that inspection tools are not conducive to inspecting the undercut surface of the product.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] like Figure 1 As shown, an embodiment of this application provides a car seat headrest back cover inspection fixture, including a frame 1, a vertical plate 2 vertically mounted on the frame 1, and a fixing component 3 mounted on the front of the vertical plate 2 for fixing the product 100, as shown. Figure 2 As shown, it also includes a gap detection component 4 disposed on the back of the vertical plate 2 and an undercut surface detection component 5 disposed on the front of the vertical plate 2, as shown. Figure 3 , Figure 4 and Figure 5As shown, the undercut surface detection component 5 includes a mounting bracket 51 with a vertical hole on the front of the vertical plate 2, a vertical rod 52 slidably mounted on the vertical hole, a reference block 53 fixedly mounted on the upper end of the vertical rod 52, and a pin 54. The mounting bracket 51 has a horizontal through hole communicating with the vertical hole. The vertical rod 52 has a positioning groove that cooperates with the pin 54. The pin 54 passes through the horizontal through hole and cooperates with the positioning groove. The vertical plate 2 has a first operating hole 201 located below the mounting bracket 51 and a second operating hole 202 located above the mounting bracket 51. The reference block 53 has a reference surface that forms a first gap 200 with the undercut 300 of the product 100.
[0024] In actual use, the operator's hand passes through the first operating hole 201 or the second operating hole 202 to pull the pin 54 out of the positioning slot. Then, the vertical rod 52 is lowered, allowing the reference block 53 to be supported by the mounting bracket 51. The product 100 is vertically fixed to the vertical plate 2 by the fixing component 3. The operator then raises the vertical rod 52 through the first operating hole 201 and inserts the pin 54 into the positioning slot to fix the vertical rod 52. At this point, the reference surface and the product 100 are interlocked 300, forming a first gap 200. The gap detection piece 4 is then held and passes through the second operating hole 202 to detect the width of the gap. After the detection is complete, the operator's hand passes through the first operating hole 201 or the second operating hole 202 to pull the pin 54 out of the positioning slot. The vertical rod 52 is then lowered, allowing the reference block 53 to be supported by the mounting bracket 51. Finally, the product 100 is removed from the fixing component 3.
[0025] In the above design, the first operating hole 201 and the second operating hole are provided to facilitate the operation of the undercut surface detection component 5 by the operator. The gap detection component 4 is set on the back of the vertical plate 2 so that the operator can operate the gap detection component 4 nearby after operating the undercut surface detection component 5 to perform gap detection, thereby improving the convenience of detection.
[0026] Specifically: such as Figure 7 As shown, the cross-section of the vertical rod 52 has at least one plane 520. The vertical hole is adapted to the cross-section of the vertical rod 52 so that the vertical rod 52 can only move up and down along the vertical hole and cannot rotate inside the vertical hole.
[0027] In the above design, the design of the vertical rod 52 and the vertical hole can ensure that the vertical rod 52 can be raised and lowered as needed, and can be lowered to avoid displacement of the product 100 when installing or removing the product 100. It can also ensure that the vertical rod can be quickly raised after the product 100 is fixed so that the reference block 53 and the product 100 are interlocked 300 to form the first gap 200. It also ensures that the reference block 53 will not rotate, and ensures that the first gap 200 will not be affected by the loosening of the fixture.
[0028] Specifically: such as Figure 2As shown, the gap detection component 4 includes a handle 41 and a first cylinder 42 and a second cylinder 43 respectively disposed at both ends of the handle 41. The diameter of the first cylinder 42 is larger than the diameter of the second cylinder 43. If the first cylinder 42 cannot be inserted into the first gap 200 and the second cylinder 43 can completely pass through the first gap 200, then the first detection dimension is qualified. It should be noted that the vertical plate 2 is provided with hooks for placing the gap detection component 4.
[0029] In actual use, remove the gap detection piece 4 from the buckle, first use cylinder 42 to perform the detection, and then use cylinder 43 to perform the gap detection. If cylinder 42 cannot be inserted into the first gap 200 and cylinder 43 can completely pass through the first gap 200, then the first detection dimension is qualified. Otherwise, the first gap 200 dimension is unqualified, that is, the product 100 is unqualified when it is reversed to 300.
[0030] In the above design, the structural design and specific implementation of the gap detection component 4 can effectively realize the width detection of the first gap 200.
[0031] Specifically: such as Figure 1 As shown, the fixing component 3 includes a positioning ring 31 disposed on the front of the vertical plate 2 and a plurality of clamping members 32 disposed circumferentially on the vertical plate 2 along the positioning ring 31. The clamping members 32 are used to apply pressure parallel to the front of the vertical plate 2 to the inner arm of the product 100.
[0032] In actual use, first keep the clamping member 32 in the unclamped state, then move the product 100 horizontally onto the positioning ring 31, and then operate the clamping members 32 one by one to make each clamping member 32 in the clamped state, so that the clamping member 32 generates an outward force on the inner wall of the product 100. Since the product 100 is a back cover with a circumferential surface, the back cover is fixed by applying outward force to different points on the inner wall of the back cover through different clamping members 32.
[0033] In the above design, the structural design and specific implementation of the fixing component 3 facilitate the application of pressure to the inner wall of the product 100 to fix the product 100.
[0034] Specifically: such as Figure 6As shown, the clamping member 32 includes a pull rod, a fixing block 321 disposed on the vertical plate 2, and an elastic fastener 325. The fixing block 321 is provided with a first sliding groove that is slidably connected to the pull rod and a second sliding groove that is slidably connected to the elastic fastener 325 and communicates with the first sliding groove. The first sliding groove is parallel to the front of the vertical plate 2, and the second sliding groove is perpendicular to the front of the vertical plate 2. The positioning ring 31 is provided with a clearance hole for the pull rod to avoid misalignment. The pull rod includes a first rod 322 that slides with the first sliding groove, a barb 323 disposed at one end of the first rod 322 located inside the positioning ring 31, and a limiting end 324 disposed at the other end of the first rod 322. The first rod 322 is provided with a first groove and a second groove that cooperate with the elastic fastener 325. The second groove is closer to the fixing block 321 than the first groove.
[0035] In actual use, when it is necessary to pick up or put down product 100, pull the elastic fastener 325 along the direction of the second slide groove, and then slide the first rod 322 inward to the inside of the positioning ring 31, so that the first rod 322 drives the barb 323 to move to a position where it will not contact product 100. Then, release the elastic fastener 325 so that the elastic fastener 325 engages with the second groove. When it is necessary to fix product 100, pull the elastic fastener 325 along the direction of the second slide groove, and then slide the first rod 322 outward to the outside of the positioning ring 31, so that the first rod 322 drives the barb 323 to apply pressure to the inner wall of product 100. Then, release the elastic fastener 325 so that the elastic fastener 325 engages with the first groove.
[0036] In the above design, the structural design and specific implementation of the clamping member 32 can effectively achieve the clamping or loosening of the product 100.
[0037] Specifically: such as Figure 6 As shown, the elastic fastener 325 includes a pin 251 that is slidably connected to the fixing block 321 through the second groove, and a spring 252 that connects the pin 251 and the fixing block 321. The spring 252 applies a spring force perpendicular to the front of the vertical plate 2 to the pin 251.
[0038] In actual use, the pin 251 is pulled along the second slide groove, causing the pin 251 to pull the spring 252. When the pin 251 is released, the spring 252 returns to its original position, causing the pin 251 to move automatically towards the first or second slot.
[0039] In the above design, the structural design and specific implementation of the clamping member 32 can effectively achieve the cooperation with the first rod 322.
[0040] Specifically: such as Figure 1 As shown, the frame 1 includes a frame 11 and casters 12 at the four corners of the frame 11. The vertical plate 2 is bolted to the frame 11.
[0041] In actual use, the frame 11 can be moved by the casters 12. When different products 100 are being tested, different vertical plates 2 can be replaced.
[0042] In the above design, the structural design and specific implementation of the frame 1 facilitate the movement of the entire inspection fixture.
[0043] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
