DETAILED DESCRIPTION

[0024] In the following, the present application is further described in conjunction with specific embodiments, and it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0025] In the description of the present application, it should be noted that for orientation words, such as terms "center", "transverse", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation and positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0027] One of the preferred embodiments of the present application is, for example, Figures 1 to 6As shown in the figure, a kind of airbag cover leather pre-coating tool clamp, including workbench 1, multiple clamping pieces 2 and multiple limiting components 10, there is the placement station for placing airbag cover A in the top middle position of workbench 1, and the first end (bottom end) of clamping piece 2 is rotatably installed at the side position of workbench 1, and the second end (top end) of clamping piece 2 has clamping part 201, limiting component 10 is installed on workbench 1 and cooperates with corresponding clamping piece 2.

[0028] It can be understood that when the airbag cover A is pre-coated and clamped, the airbag cover A is first placed on the placement station on the workbench 1, and the placement station can limit the horizontal direction of the airbag cover A; then the clamping part 201 of the clamping piece 2 is rotated towards the airbag cover A until it abuts against it, the clamping part 201 abuts against the top end position of the airbag cover A, and finally the clamping piece 2 is locked by the limiting component 10, so that the airbag cover A is limited and fixed in the horizontal and vertical directions. Similarly, when the airbag cover A is loosened, the locking of the clamping piece 2 by the limiting component 10 is first released, and then the clamping piece 2 is reversed and the clamping part 201 is moved away from the airbag cover A, which is simple and convenient.

[0029] As can be seen, the clamping and loosening of the airbag cover A can be achieved by rotating the clamping piece 2, and the clamping method is simple and fast. Compared with the movable clamping and fixing method of the clamping part 201 in the prior art, the clamping piece 2 in the present application has a larger avoiding space after being loosened by rotation, so that the operation space of the leather coating is increased, and the work efficiency of the workers is improved.

[0030] It should be noted that, as shown in the figure, Figure 3 A boss 9 is detachably installed (such as bolted) on the top middle of the workbench 1, thereby forming the above-mentioned placement station; of course, the shape and size of the boss 9 are adapted to the airbag cover A, and when different models of airbag cover A are used, we only need to disassemble and replace the corresponding boss 9.

[0031] Further, the number of clamping pieces 2 is preferably three, as shown in the figure, Figure 3 Three clamping pieces 2 are located on the left side, right side and rear side of the workbench 1, and the front side is the operation side of the workers. Such design not only facilitates the operation of the workers, but also enables the three clamping pieces 2 to stably clamp and fix the airbag cover A.

[0032] The structure of the limiting component 10 is not limited in the present application, and the following provides a specific embodiment for illustration:

[0033] As shown in the figures, Figure 5 And Figure 6As shown, the limiting assembly 10 comprises a limiting pin 1001 movably arranged on the workbench 1. The bottom end of the clamping piece 2 is rotatably installed on the workbench 1 through a rotating shaft 202. A fixed ring 11 is fixedly installed outside the rotating shaft 202, and a plurality of limiting grooves 12 are arranged outside the fixed ring 11.

[0034] It can be understood that when the clamping piece 2 rotates, the clamping piece 2 will drive the rotating shaft 202 and the fixed ring 11 to rotate synchronously. When the clamping piece 2 abuts against the airbag cover A, the limiting grooves 12 correspond to the limiting pin 1001 at this time, and then the limiting pin 1001 is inserted into the limiting grooves 12 to realize the limiting locking of the clamping piece 2. Of course, the limiting grooves 12 can be provided with a plurality of limiting grooves 12. For example, after the clamping piece 2 is reversed and loosened, the clamping piece 2 can also be locked through the cooperation of the limiting pin 1001 and the limiting grooves 12. This is to prevent the shaking of the clamping piece 2 from affecting the pre-coating process.

[0035] Further, in order to ensure the stability after limiting, the limiting pin 1001 can be movably installed in the workbench 1 through an elastic member (such as a spring). When the clamping piece 2 is locked, the limiting pin 1001 can be stably inserted into the limiting grooves 12 under the action of the elastic force, thereby improving the stability of the clamping piece 2 after locking.

[0036] Based on the above embodiment, it should be understood that when the locking of the clamping piece 2 is released, the limiting pin 1001 needs to be separated from the limiting grooves 12 by pulling. The limiting pin 1001 itself is limited by the spring, so it may be more laborious during pulling.

[0037] Therefore, in order to solve the above technical problems, in one of the embodiments of the present application, as shown in Figure 5 and Figure 6 , a plurality of sleeves 13 are installed on the workbench 1, the sleeves 13 are sleeved outside the corresponding limiting pins 1001, and a push piece 14 is installed at the end of the limiting pin 1001.

[0038] Specifically, as shown in (a) of Figure 6 , a beveled slope 15 is arranged outside the sleeve 13. Of course, the beveled slope 15 has a slope bottom and a slope top. When the clamping piece 2 is locked, the push piece 14 cooperates with the slope bottom at this time, as shown in (b) of Figure 6 . When the clamping piece 2 is unlocked, the worker only needs to rotate the limiting pin 1001 through the push piece 14. During rotation, the push piece 14 will be wedge-shaped extrusion matched with the beveled slope 15, so that the limiting pin 1001 moves while rotating, and moves away from the limiting grooves 12 to realize the unlocking of the clamping piece 2, as shown in Figure 6(c) shown in the figure. As can be seen, by rotating the unlocking mode, compared with directly pulling the limit pin 1001 to unlock, the unlocking mode in the application is more labor-saving and convenient.

[0039] In one embodiment of the application, as shown in the figure, Figure 2 The base 4 is arranged below the workbench 1, and the workbench 1 is connected to the base 4 through the lifting rod 3. The lifting rod 3 can adjust the height of the workbench 1 to adapt to the operation of workers of different heights and improve the comfort of operation.

[0040] Specifically, the lifting rod 3 includes a lower steel rod 303, an upper steel rod 301, and a limiting screw rod 302. The lower steel rod 303 is vertically fixedly installed at the top middle part of the base 4. The upper steel rod 301 is slidingly arranged in the lower steel rod 303. The limiting screw rod 302 is threadedly connected to the upper end of the side of the lower steel rod 303. It can be understood that when adjusting, the upper steel rod 301 is slid up and down in the lower steel rod 303. When the upper steel rod 301 is slid to the appropriate height, the limiting screw rod 302 is tightened and abuts against the outside of the upper steel rod 301, so that the upper steel rod 301 is locked. Of course, the lifting rod 3 can also be electrically driven, but since it is not adjusted frequently, the manual adjustment mode is preferred.

[0041] Further, in order to facilitate the leather covering of the airbag cover A in different directions later, the workbench 1 can be installed at the movable end (i.e., the top end of the upper steel rod 301) of the lifting rod 3 through the driving device 8, and the workbench 1 is adjusted in rotation through the driving device 8. Specifically, the driving device 8 can be started through the foot switch 7, that is, the foot switch 7 is electrically connected to the driving device 8. When adjusting, the worker can start the workbench 1 to rotate to the set angle by stepping on the foot switch 7. Of course, there are various control modes for rotation, including but not limited to the following two modes:

[0042] Mode one: the workbench 1 is continuously rotated by continuously stepping on the foot switch 7, and the foot switch 7 is released when the workbench 1 is rotated to the appropriate angle. Mode two: the airbag cover A generally needs to be covered on four sides, so the workbench 1 is set to rotate ninety degrees as a unit, that is, the workbench 1 is rotated ninety degrees each time the foot switch 7 is stepped on. That is, each rotation makes the side of the airbag cover A face the front of the worker, and such angle setting rotation mode can improve the work efficiency.

[0043] In this embodiment, as shown in the figure, Figure 1As shown, the fixture for pre-wrapping leather for airbag covers also includes a bracket 5. The bracket 5 is located next to the workbench 1 and has a multi-layered structure. The bracket 5 can store items for wrapping, such as knives and heat guns, so that workers can easily access them during operation and improve work efficiency.

[0044] Furthermore, such as Figure 1 As shown, a shadowless lamp (not shown) can be installed above the workbench 1 via the work frame 6. The shadowless lamp can provide uniform illumination to the workbench 1, thus ensuring sufficient light during the pre-wrapping of the airbag cover A leather, guaranteeing the wrapping quality. The design of the shadowless lamp avoids the influence of shadows on the operator's vision, making the operation more precise and reducing eye fatigue during operation.

[0045] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
