[0024] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0025] like Figures 1 to 3 As shown, a hardware deformation detection fixture 10 includes a base 100 and two detection components 200. The base 100 has a material loading groove 110 for receiving irregularly shaped hardware parts 20. Several guide holes 120 are respectively formed on the inner walls of both sides of the material loading groove 110. The two detection components 200 are located on opposite sides of the base 100. In one of the detection components 200, the detection component 200 includes a sliding plate 210, a guide rod 220, an elastic element 230, a first detection rod 240, and at least one second detection rod 250. The sliding plate 210 is slidably disposed on the base 100, and one end of the guide rod 220 is provided with... The first detection rod 240 is placed on the slide plate 210 and passes through one of the guide holes 120. The first detection rod 240 is slidably connected to the guide rod 220. The elastic element 230 is sleeved on the guide rod 220 and abuts against the slide plate 210 and the first detection rod 240 respectively. Each second detection rod 250 is set on the slide plate 210 and passes through a guide hole 120 respectively. When the slide plate 210 is subjected to force to approach the loading trough 110, the first detection rod 240 abuts against the irregular hardware part 20 first, and then each second detection rod 250 abuts against the irregular hardware part 20.

[0026] It should be noted that the detection principle of the hardware deformation detection fixture 10 of this application is as follows: The outer wall of the irregularly shaped hardware 20 has several round protrusions. A fixedly distributed first detection rod 240 and several second detection rods 250 are used to simultaneously insert and position each round protrusion. When the deformation of the irregularly shaped hardware 20 exceeds a preset range, the first detection rod 240 and each of the second detection rods 250 cannot be accurately and unobstructedly inserted into the corresponding round protrusions. Thus, by observing whether the first detection rod 240 and each of the second detection rods 250 are accurately and unobstructedly inserted into the corresponding round protrusions, it is possible to quickly determine whether the irregularly shaped hardware has deformed beyond the preset range. Furthermore, it should be noted that in this application, the round protrusions on the outer wall of the irregularly shaped hardware 20 are used as detection points for deformation detection. It is conceivable that for any hardware with an irregular structure, when there are structures including but not limited to circles, squares, stars, and spheres on its outer wall, they can all be used as detection points for deformation detection. Therefore, the irregularly shaped hardware 20 and the round protrusions on it shown in this application are only shown to facilitate the explanation of the working principle of the hardware deformation detection fixture 10 of this application, and should not be construed as limiting the structure of the hardware with an irregular structure. Therefore, the structure of the material tray 110, the distribution of the first detection rod 240, and the second detection rods 250 in the hardware deformation detection fixture 10 of this application can be deformed according to the specific structure of the hardware with an irregular structure, so that the material tray 110 can stably accommodate the irregularly shaped hardware 20. Specifically, the slide plate 210 is slidably mounted on one side of the base 100. One end of each second detection rod 250 is fixed to the side of the slide plate 210 near the base 100 with screws, and the other end of each second detection rod 250 passes through the guide hole 120 at the corresponding position. One end of the guide rod 220 is also fixed to the side of the slide plate 210 near the base 100 with screws. The guide rod 220 also passes through the first detection rod 240, so that the first detection rod 240 is slidably connected to the guide rod 220, and the first detection rod 240 also passes through the guide hole 120 at the corresponding position. Further, the elastic member 230 is sleeved on the guide rod 220, and the elastic member 230 abuts against the first detection rod 240 and the slide plate 210 respectively. In one embodiment, the elastic member 230 is a helical spring. Thus, under the elastic thrust of the elastic member 230, the first detection rod 240 tends to move away from the guide rod 220 and closer to the loading trough 110. It should be noted that the first detection rod 240 / second detection rod 250 and the guide hole 120 are fitted together. Thus, when the slide plate 210 is pushed and slides relative to the base 100, the first detection rod 240 and each of the second detection rods 250 can slide along the guide hole 120 at the corresponding position to extend into the material loading groove 110.The first detection rod 240 is inserted into one of the round protrusions of the irregular hardware part 20 before each of the second detection rods 250. The first detection rod 240 is used to initially position the irregular hardware part 20. This is because when the irregular hardware part 20 is placed in the material loading groove 110, there will inevitably be gaps between the irregular hardware part 20 and the material loading groove 110. In order to avoid false measurements by the first detection rod 240 and each of the second detection rods 250 due to material placement errors, the first detection rod 240 is set to initially position the irregular hardware part 20. Thus, after the first detection rod 240 is inserted into the corresponding round protrusion on the irregular hardware part 20, as the slide plate 210 continues to approach the base 100, the first detection rod 240 is held in place by the irregular hardware part 20, the elastic member 230 is compressed, and each of the second detection rods 250 extends into the material loading groove 110 to be inserted into the corresponding round protrusion on the irregular hardware part 20. Thus, when the first detection rod 240 and each of the second detection rods 250 can be accurately and unobstructedly inserted into the corresponding round protrusions of the irregular hardware part 20, it indicates that the deformation degree of the irregular hardware part 20 is within the predetermined deformation range. When one of the first detection rod 240 or each of the second detection rods 250 cannot be accurately and unobstructedly inserted into the corresponding round protrusion, it indicates that the deformation degree of the irregular hardware part 20 exceeds the acceptable range. Therefore, compared to using measuring tools, the hardware deformation detection fixture 10 of this application has a simple structure, is easy to operate, and provides intuitive measurement results, allowing for quick determination of the deformation degree of the irregular hardware part 20 based on the positional status of the first detection rod 240 and the second detection rod 250.

[0027] like Figure 1 and Figure 2 As shown, in one embodiment, the detection component 200 further includes two guide blocks 260, which are spaced apart on the base 100 and both guide blocks 260 pass through the slide plate 210.

[0028] It should be noted that in order for the slide plate 210 to slide stably relative to the base 100, two guide blocks 260 are installed on the base 100 by screws. Both guide blocks 260 pass through the slide plate 210, so that the slide plate 210 slides along the guide blocks 260.

[0029] In one embodiment, the guide block 260 has a polyhedral structure. Thus, the slide plate 210 has a polygonal hole structure that matches the guide block, thereby preventing the slide plate 210 from rotating relative to the guide block 260 and improving the sliding stability of the slide plate 210.

[0030] like Figure 3 As shown, in one embodiment, both the first detection rod 240 and the second detection rod 250 have detection holes 201 along the axial direction.

[0031] It should be noted that the detection hole 201 is used to fit into the round protrusion of the irregular hardware 20. Therefore, the detection hole 201 needs to be specifically opened according to the diameter of the corresponding round protrusion to ensure that the first detection rod 240 and the second detection rod 250 can accurately and unimpededly detect the deformation of the irregular hardware 20.

[0032] like Figure 3 As shown, in one embodiment, each detection hole 201 has a chamfered portion 202 on the end near the material loading tank 110.

[0033] It should be noted that when the first detection rod 240 and the second detection rod 250 approach the round protrusion of the irregular hardware 20 for deformation detection, in order to enable the round protrusion to be quickly aligned with the detection hole 201, a chamfer 202 is provided at the opening position of the detection hole 201. The chamfer 202 is used to guide the round protrusion of the irregular hardware 20, thereby improving the deformation detection efficiency of the first detection rod 240 and the second detection rod 250 on the irregular hardware 20.

[0034] like Figure 3 As shown, in one embodiment, a locking boss 221 is provided on one end of the guide rod 220 located on the first detection rod 240, and a locking step 241 is provided inside the first detection rod 240. The locking step 241 is used to engage the locking boss 221.

[0035] In this way, the locking step 241 engages with the locking boss 221, preventing the first detection rod 240 from sliding off the guide rod 220.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, a pull block 270 is also provided on the side of the slide plate 210 away from the base 100.

[0037] Thus, the pull block 270 facilitates the application of a pushing force to the slide plate 210, thereby causing the slide plate 210 to drive the first detection rod 240 and the second detection rod 250 to slide relative to the base 100.

[0038] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
