"greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of the words "first," "second," and "third" is only for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.

[0030] The following is combined with Figure 1-4 , an embodiment of a positioning fixture for a vehicle door handle inner cover plate of the utility model is further described in detail.

[0031] A positioning fixture for the inner cover of a door handle, such as Figure 1 、 2 As shown, it includes a mold cavity jig 1, an elastic support component 2, a locking component 3 and a baffle 4. The mold cavity jig 1 is provided with the same points, holes and slots as the inner cover of the door handle; the elastic support component 2 is fixedly connected to the bottom end of the mold cavity jig 1, and there are multiple elastic support components 2, and the multiple elastic support components 2 are respectively distributed along the points, holes and slots on the mold cavity jig 1; one end of the locking component 3 is arranged opposite to the top of the elastic support component 2, and the locking component 3 is connected to the elastic support component 2; the baffle 4 is used to isolate and shield the non-sprayed surface, and the baffle 4 is arranged around the mold cavity jig 1, and the baffle 4 is arranged at the same height as the mold cavity jig 1.

[0032] Specifically, the size, shape, and structure of the mold cavity jig 1 are identical to those of the inner cover plate of the vehicle door handle, and the inner cover plate of the vehicle door handle can be perfectly covered on the mold cavity jig 1. Through precise size and shape matching, the inner cover plate of the vehicle door handle can be quickly positioned and securely installed, reducing installation and disassembly time, thereby improving loading and unloading efficiency. During the painting process, in order to prevent other surfaces from being contaminated by the paint surface, a baffle 4 is provided during the painting process so that only the designated area can be sprayed, avoiding contamination of the non-sprayed surface and improving the painting quality. The baffle 4 is composed of a plurality of mutually spliced snap plates, and the side of the baffle 4 facing the mold cavity jig 1 is sprayed with a nano-coating for preventing paint adhesion. In actual application, the bottom end of the baffle 4 is slightly larger than the top end. In practical application, in order to prevent paint from adhering to the baffle 4, a nano-coating is sprayed on the inner side of the baffle 4. The principle is the same as the coating sprayed in a non-stick pan, making it convenient to clean.

[0033] When fixing and positioning the inner cover of the door handle, the three-point positioning principle is adopted, such as Figure 3 As shown, by installing elastic support components 2 at key points, holes, and slots in the positioning fixture, the inner cover plate's shape is maintained by preload, preventing product deformation. A locking component 3, in conjunction with the elastic support component 2, ensures that the inner cover plate does not accidentally fall off during the painting process. It is worth noting that the positioning fixture design of this utility model has a certain degree of versatility and can adapt to different models of door handle inner cover plates, improving equipment utilization and flexibility.

[0034] In this embodiment, the elastic support assembly 2 includes a support seat 21, a support rod 22 and an elastic support block 23. The support seat 21 abuts against the side wall of the mold cavity jig 1, and the vertical cross-section of the support seat 21 is a T-shaped structure. At least two positioning holes 211 are provided at the top of the support seat 21, and positioning pins are inserted into the positioning holes 211.

[0035] Specifically, the support seat 21 supports the mold cavity jig 1 according to the force points at different positions. At the same time, the positioning holes 211 opened on the support seat 21 facilitate the selection of different positioning types for connection, so that it can adapt to multiple mold cavity jigs 1; the top end of the positioning pin is clamped in the corresponding position of the mold cavity jig 1, thereby completing the preliminary positioning of the mold cavity jig 1, so as to facilitate subsequent rapid fixation.

[0036] In this embodiment, if Figure 3 As shown, there are multiple support rods 22, and the multiple support rods 22 are evenly arranged on the inner side of the baffle 4, and the support rods 22 include a first support rod 221, a second support rod 222 and a third support rod 223, and the heights of the first support rod 221, the second support rod 222 and the third support rod 223 increase sequentially.

[0037] Specifically, the bottom end of the support rod 22 is fixed to the workbench by screws, wherein the top end of the first support rod 221 in the support rod 22 is connected to the elastic support block 23, and the elastic support block 23 is used to abut the point of the mold cavity jig 1; and when the elastic support block 23 abuts against the mold cavity jig 1, it can maintain the shape of the inner cover plate of the door handle according to the change of the preload force of the mold cavity jig 1 to prevent it from deformation; at the same time, the number of the first support rod 221 can be set according to the actual number of points of the mold cavity jig 1; a fixed sleeve 24 is connected to the top end of the second support rod 222, and the fixed sleeve 24 is used to pass through the hole of the mold cavity jig 1, and the fixed sleeve 24 and the second support rod 222 are detachably connected by setting a connecting ring; the fixed sleeve 24 can not only pass through the mold cavity jig The mold fixture 1 can also synchronously pass through the holes on the inner cover plate of the door handle, so that the fixed sleeve 24 limits the position of the inner cover plate of the door handle to prevent it from deflecting during the painting process and affecting the painting effect; the number of the second support rods 222 can also be set according to the number of holes, and the third support rod 223 is used to fix the slot of the mold cavity fixture 1, and the top of the third support rod 223 is provided with a straight slot 2231 that is compatible with the locking block 34. The slot of the mold cavity fixture 1 is generally a groove opened on the side wall. In order to clamp and fix its slot, the straight slot 2231 on the third support rod 223 is used to cooperate with the locking assembly 3, so that the third support rod 223 is stably abutted in the slot, further limiting the installation position of the inner cover plate of the door handle and improving its stability.

[0038] In this embodiment, if Figure 4 As shown, the locking assembly 3 includes a base 31, a locking clamp 32, a connecting plate 33 and a locking block 34. The locking clamp 32 is fixedly connected to the top of the base 31, and one side of the locking clamp 32 is connected to the connecting plate 33 with a hinge 35. One end of the connecting plate 33 is hinged to the locking clamp 32 through the hinge 35, and the other end is connected to the locking block 34 through a fixing screw.

[0039] Specifically, multiple locking assemblies 3 are provided, arranged according to the position of the support base 21, and located outside the shielding plate 4. When locked, the locking block 34 on the connecting plate 33 cooperates with the straight notch 2231 on the support base 21, thereby completing the positional fixation of the door handle inner cover. The locking block 34 has a conical structure and can be inserted into the positioning hole 211 or the straight notch 2231. The locking assembly 3 is manually fixed by manually pressing the locking clamp 32 downward, which drives the connecting plate 33 downward through the hinge 35, thereby driving the locking block 34 to insert into the straight notch 2231 or the positioning hole 211 to complete the fixed position. Similarly, the locking clamp 32 can be pressed upward to complete the unlocking.

[0040] It is worth noting that, in addition to manually controlling the locking clamp 32 , an electric drive method can also be used. The present invention only lists one of the methods and does not limit them in sequence.

[0041] The working principle of this utility model:

[0042] During the process of painting the inner cover plate of the door handle, the inner cover plate of the door handle is first installed on the mold cavity jig 1 with the same shape and structure as it, and then the elastic support component 2 is used to fix and support the point positions, hole positions and slot positions of the inner cover plate of the door handle. Finally, the locking component 3 is used to fix and limit the inner cover plate of the door handle to ensure that the inner cover plate of the door handle is stably installed on the mold cavity jig 1 during the painting process, and effectively avoids the risk of deformation and falling during the painting process, thereby ensuring the stability of the product during the processing process and improving the jetting effect and the yield rate.

[0043] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
