[0035] Example 1:

[0036] Please refer to Figure 1-8 This embodiment provides a labor-saving jig for the front hood of an automobile inner panel robot painting project, which mainly includes a bottom fixing device 10, an upper fixing device 20, a first support rod 30, a second support rod assembly 40 and a tension adjustment device 50;

[0037] The bottom fixture 10, first strut 30, second strut assembly 40, and upper fixture 20 are sequentially connected. Specifically, one end of the first strut 30 is hinged to the bottom fixture 10, and the other end is hinged to the second strut assembly 40. The other end of the second strut assembly 40 is hinged to the upper fixture 20. All of the above hinged connections can be achieved by hinge pins.

[0038] The tension adjustment device 50 includes an angle control connecting rod 51, a spring assembly and a slide limiter 53; the slide limiter 53 is fixed to one side of the first strut 30, and a straight slide 531 is formed in the slide limiter 53, and the straight slide 531 is arranged along the length direction of the first strut 30; the angle control connecting rod 51 is arranged in an "L" shape, one end of the angle control connecting rod 51 is connected to the second strut assembly 40 through a hinge pin, and the other end is slidably connected to the straight slide 531, so that the end of the angle control connecting rod 51 can translate in the straight slide 531; the spring assembly is arranged in the space enclosed by the first strut 30, the second strut assembly 40 and the angle control connecting rod 51.

[0039] Based on the above structure, the labor-saving jig for the front hood of the automobile inner panel robot painting project of this embodiment can provide an effective working space and necessary opening positions for the related painting engineering operations of the automobile front hood and interior, making the operation easy and labor-saving, reducing the labor intensity of the related operators, and improving the work efficiency of the related engineering workstations. In this embodiment, a slide limiter 53 is fixed on one side of the first support rod 30, and a linear slide 531 is provided in the slide limiter 53 along the length direction of the first support rod 30, so that the end of the angle control connecting rod 51 is slidably connected to the linear slide 531. In this way, the linear slide 531 constrains the end of the control connecting rod, effectively preventing the angle control connecting rod 51 from deviating, shaking, or getting stuck during use, and more accurately and stably controlling the opening and closing amount of the automobile front hood.

[0040] Specifically, the first support rod 30 of this embodiment is a high-strength support rod, mainly used to support the weight of the machine cover and the fixture itself. The second support rod assembly 40 is a foldable rod, including a folding support rod 41 and an auxiliary support rod 42. The end of the folding support rod 41 and the end of the auxiliary support rod 42 are hinged by a hinge pin. The folding support rod 41 is arranged near the upper fixing device 20; the hinge between the folding support rod 41 and the auxiliary support rod 42 is provided with a safety lock 43, and the safety lock 43 is used to fix the relative angle between the folding support rod 41 and the auxiliary support rod 42. By making the second support rod assembly 40 foldable, when not in use, the folding support rod 41 and the auxiliary support rod 42 can be folded to reduce the size of the fixture, making it easier for the operator to use, transport, and clean, thereby reducing space. The safety lock 43 consists of a rotating block and a card slot. One end of the rotating block is connected to the auxiliary support rod 42, and the other end is provided with a lever, and the card slot is fixed to the other side of the auxiliary support rod 42; when in use, the folding support rod 41 and the auxiliary support rod 42 are opened, and then the rotating block is rotated by the lever to make it snap into the card slot, fixing the relative angle between the folding support rod 41 and the auxiliary support rod 42; when disassembling, the rotating block is pushed out of the card slot by the lever, so that the folding support rod 41 and the auxiliary support rod 42 can be folded in half, thereby achieving the purpose of reducing the volume of the fixture.

[0041] The spring assembly includes a tension spring 521 and a spring force regulator 522; the tension spring 521 is specifically a round wire tension coil spring. The tension of the round wire tension coil spring reduces the weight of the front hood, thereby saving effort. The spring force regulator 522 is specifically a double-groove spring force regulator 522, which is used to precisely adjust the elastic coefficient of the round wire tension coil spring. The spring force regulator 522 includes a first hook and a second hook that are threadedly connected to each other. The hook of the first hook is hooked to the angle control connecting rod 51 via a connecting block. The hook of the second hook is connected to the end of the tension spring 521. The other end of the tension spring 521 is rotatably connected to the auxiliary support rod 42.

[0042] The bottom fixture 10 of this embodiment is designed to be fastened to the middle of the lower crossbar of a car's radiator, or to the middle of a dedicated crossbar. The bottom fixture 10 is equipped with a bottom buckle safety lock 11, which is rotatably mounted on one side of the bottom fixture 10. Once the bottom fixture 10 is fastened, the bottom buckle safety lock 11 rotates to clamp the bottom fixture 10 against the crossbar, thereby fixing the relative position of the bottom fixture 10 to the car. This ensures the stability and safety of the entire fixture.

[0043] The upper fixing device 20 of this embodiment is used to support the front hood, wherein the upper fixing device 20 includes a hood fastening assembly 21 and an operating handle 22. Specifically, the hood fastening assembly 21 includes a positioning carrier 211 and a hood connecting lock 212. The positioning carrier 211 is provided with a U-shaped slot 2111, which engages with the raised lock on the inner side of the front hood. During use, the U-shaped slot 2111 can quickly position the raised lock on the inner side of the front hood, thereby improving the operator's working time. The hood connecting lock 212 is used to fix the relative position of the positioning carrier 211 and the front hood, that is, to lock the raised lock on the inner side of the front hood in the U-shaped slot 2111. The hood connecting lock 212 of this embodiment is made of spring steel, such as a torsion spring buckle, etc. The raised lock on the inner side of the front hood is pushed into the U-shaped slot 2111 and locked manually. The torsion spring buckle is used to generate elastic deformation and is locked after automatic reset. It can be unlocked by toggling the lever at one end of the spring steel, which can be quickly loaded and unloaded, thereby improving safety and convenience of operation.

[0044] Please refer to Figure 3-4As shown, the operating handle 22 is used by the manipulator and personnel to hold during operation, providing safe and convenient access to the machine cover. The operating handle 22 of this embodiment is generally T-shaped and comprises a relatively perpendicular curved rod 221 and a handle 222. The curved rod 221 primarily serves as a connection, while the handle 222 is primarily for the manipulator and personnel to hold during operation. The handle 222 is pivotally connected to the end of the curved rod 221 and has anti-slip features at both ends. One end of the curved rod 221 is connected to the positioning carrier 211 through a rotating shaft, and the other end is connected to the handle 222, so that the working handle 22 can rotate relative to the positioning carrier 211; a handle opening and closing lock buckle 223 is provided between the positioning carrier 211 and the working handle 22, and the handle opening and closing lock buckle 223 is used to fix the relative angle between the positioning carrier 211 and the working handle 22. When personnel are working, some projects require the handle 222 to be rotated to the inside of the machine cover. The positioning pin of the handle opening and closing lock buckle 223 can be pulled out to unlock it, so that the handle 222 can be quickly and conveniently recovered to the inside of the machine cover, meeting the various painting operations and improving operability and safety.

[0045] This embodiment also includes a support opening fixing device 60, which includes a hook 61 and a rotating support rod 62. The hook 61 is fixed to the auxiliary support rod 42. One end of the rotating support rod 62 is rotatably connected to the first support rod 30 via a rotating shaft, and the other end can be snapped onto the hook 61. The end of the rotating support rod 62 is provided with a clamping block 63, which defines a first clamping slot 631 and a second clamping slot 632. During operation, the support rod 62 is rotated to engage the first clamping slot 631 or the second clamping slot 632 with the hook 61, thereby suspending the front hood at different openings to meet the needs of different engineers. Furthermore, the support opening fixing device 60 also includes a limiter 64 fixed to the first support rod 30. When the rotating support rod 62 rotates to be parallel to the first support rod 30, the limiter 64 abuts against the rotating support rod 62, limiting further rotation of the rotating support rod 62.

[0046] In this embodiment, the bottom fixture 10 and the first support rod 30, the first support rod 30 and the auxiliary support rod 42, the first support rod 30 and the angle control connecting rod 51, the auxiliary support rod 42 and the angle control connecting rod 51, and the folding support rod 41 and the upper fixture 20 are all connected by high-strength, tight-fitting hinge pins with shoulder openings. These high-strength locating pins provide improved concentricity, parallelism, wear resistance, and surface accuracy for the fixture during repeated opening and closing of the front hood. Other structural forms in this solution can be found in the prior art and are not described here in detail.

[0047] Although certain components and embodiments of the present application have been illustrated and described, many modifications and changes (e.g., changes in size, dimensions, structure, shape and proportions of the various elements, mounting arrangements, use of materials, colors, orientations, etc.) may occur to those skilled in the art without actually departing from the scope and spirit of the claims.

[0048] Finally, it should be noted that the above-mentioned implementation mode is only a preferred embodiment mode of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
