[0025] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0026] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0027] In the present disclosure, unless otherwise stated, directional words such as "upper", "lower", "top", and "bottom" are generally defined under the normal use of the fixing device provided by the present disclosure. Figure 3 In the illustrated drawing directions, "inside" and "outside" refer to the inside and outside of the corresponding component contours. In addition, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0028] Take automotive parts as an example, such as bumpers, ultrasonic radars, unhooking covers, radar covers, and various interior parts. When conducting paint performance tests on painted automotive parts, for example, adhesion tests require fixing the parts, using a grid knife to draw some squares on the test surface, and quickly pulling it up with a certain amount of force to count the percentage of squares falling off. For some products with special structures and small sizes, the existing clamps are not suitable, and the flatness of the test surface cannot be guaranteed, and thus the accuracy of the test results cannot be guaranteed.

[0029] To solve the above problems, Figures 1 to 3 As shown, the present disclosure provides a clamping member 3, which includes a connecting rod 31 and a ball head 32 installed at one end of the connecting rod 31, and the other end of the connecting rod 31 is a fixed end, which can be directly fixed on a wall, wherein the ball head 32 can be close to or away from the fixed end of the connecting rod 31 to clamp products 2 of different shapes.

[0030] Here, it should be noted that product 2 is not limited to automotive parts, nor is it limited to the fixation of painted products during performance testing. Various types of products, such as household appliance parts, various functional devices, etc., can be fixed during product processing and testing, and all fall within the scope of protection of the present disclosure.

[0031] The present disclosure includes an embodiment in which there is one clamping member 3, and the product 2 is clamped between the ball head 32 and a wall or any fixed plane. The present disclosure also includes an embodiment in which there are at least two clamping members 3 arranged opposite to each other, and the product is clamped between the two ball heads 32. Both embodiments can achieve clamping and fixing of the product 2 and belong to the protection scope of the present disclosure.

[0032] The present disclosure includes an embodiment in which the clamp 3 is directly fixed on a wall or any fixed plane. In the present disclosure, the clamp 3 can be installed in the base 1, and the fixed end of the connecting rod 31 is installed on the inner wall of the base 1. The base 1 and the clamp 3 together constitute a fixing device of the product provided by the present disclosure.

[0033] In the present disclosure, the base 1 may be made of PP (polypropylene), the connecting rod 31 may be made of stainless steel, and the ball head 32 may include a metal ball and a wear-resistant layer wrapped around the outer surface of the metal ball, for example, a stainless steel ball head wrapped with a PU (polyurethane) sponge, which can achieve soft contact with the surface of the product 2 to avoid scratching and damage to the product 2, and increase the contact area with the product 2 through partial deformation of the ball head 32 itself, thereby improving the clamping strength. The wear-resistant layer on the surface of the ball head 32 can keep the surface of the clamp 3 from being worn by the product 2 during multiple adjustments and clamping processes, thereby avoiding affecting its clamping function.

[0034] In the clamping member 3 provided in the present disclosure, the position of the ball head 32 relative to the fixed end can be adjusted based on the actual shape of the product 2. If the size of the clamped product 2 is small, the ball head 32 is adjusted in a direction away from the fixed end. If the size of the clamped product 2 is large, the ball head 32 is adjusted in a direction close to the fixed end, so as to adapt to the shape of the product 2. The ball head 32 can abut against the surface of the product 2 to stably clamp and fix the product 2. The clamping member provided in the present disclosure can take into account the fixation of products 2 of various special-shaped structures and sizes, especially when the product is tested for performance, it can ensure the flatness of the test surface of the product 2 and the accuracy of the test results. The fixation of special-shaped products can be completed easily and quickly, reducing the difficulty of work and improving work efficiency.

[0035] The present disclosure includes an embodiment in which a clamping member 3 is provided in the base 1 , and the product 2 can be pressed against the inner side wall opposite to the base 1 by the clamping member 3 , thereby clamping and fixing the product 2 .

[0036] The present disclosure also includes an embodiment in which a plurality of clamping members 3 are disposed in the base 1, and the plurality of clamping members 3 are arranged circumferentially around the product 2, such as Figure 1 and Figure 2As shown, according to the shape of the product 2, the position of the ball head in each clamping member 3 is individually adjusted so that the ball head 32 of each clamping member 3 abuts against the surface of the product 2 to play a fixing role. This not only ensures the stability of the clamped product 2, but also increases the application range of the fixing device, improves its versatility, and reduces the manufacturing cost of the fixing device.

[0037] There are many ways to adjust the axial position of the ball head 32 at one end of the connecting rod 31. For example, the connecting rod 31 is designed as a telescopic rod. In an exemplary embodiment provided by the present disclosure, the connecting rod 31 can be a threaded rod with external threads, and the ball head 32 has a threaded hole connected to the threaded rod, wherein the depth of the threaded hole is less than the diameter of the ball head 32. Figure 3 Take the clamping member 3 on the left side of the middle as an example. For example, when the ball head 32 is screwed clockwise, the ball head 32 is adjusted to the right. When the ball head 32 is screwed counterclockwise, the ball head 32 is adjusted to the left. The depth of the threaded hole is less than the diameter of the ball head 32, which can prevent the connecting rod 31 from passing through the ball head 32 and affecting the clamping effect. Accordingly, the depth of the threaded hole is the adjustment range of each ball head 32, which can be designed as needed. In another exemplary embodiment of the present disclosure, the connecting rod 31 is an electric telescopic rod, and the ball head 32 is fixed at one end of the electric telescopic rod. The length of the electric telescopic rod is automatically adjusted to make the ball head 32 close to or away from the product 2. In other embodiments, the connecting rod 31 can also be designed as a multi-section rod, with two adjacent sections of the rod being connected in a socketed manner, and multiple clamping positions are provided along the axial direction. By adjusting the position of the clamping of the two, the length of the connecting rod 31 can be adjusted, thereby adjusting the position of the ball head 32.

[0038] In this embodiment, if Figure 1 and Figure 2 As shown, the base 1 can be a square structure, and at least one clamping member 3 is provided on each side wall of the square structure, for example, two clamping members 3 are provided on each side wall, so that a total of eight clamping members 3 are designed in the base 1, and the adjustment methods of the ball heads 32 in the multiple clamping members 3 can be the same or different, all of which belong to the protection scope of the present disclosure. You can choose to loosen some of the ball heads 32 to replace and adjust the test surface of the product 2, which is simple and convenient to operate.

[0039] like Figure 3 As shown, the fixing device provided by the present disclosure also includes a pad 4 arranged in the base 1, and the product 2 is placed on the pad 4. The shape of the pad 4 can be adaptively designed according to the shape of the base 1. The pad 4 has a variety of specifications with different thicknesses, and the pad 4 of corresponding thickness can be selected according to the product 2. The pad 4 can be made of elastic material, such as EPP (foamed polypropylene) material, such as Figure 3As shown, when the product 2 is placed on the cushion block 4, the cushion block 4 itself will be deformed to a certain extent under the gravity of the product 2, so as to play an auxiliary fixing role for the product 2, and facilitate the subsequent adjustment of the ball heads 32 of the multiple clamping members 3 to further fix the product 2. The cushion block 4 cooperates with the multiple clamping members 3 to ensure the stability of the product 2 on the fixing device.

[0040] like Figure 1 and Figure 2 As shown, the cross section of the product 2 can be any one of round, square, diamond, and special shapes. The fixing device can fix products 2 of any shape, not limited to the above-mentioned ones. In addition, the product 2 can be a component with a surface coated with paint, which is used for paint performance testing. Of course, the fixing device is also suitable for fixing welding components, performance testing of other components, etc., and the present disclosure does not limit this.

[0041] Taking painted automobile parts as an example, when using the fixing device provided by the present invention for testing, a pad 4 of appropriate thickness is selected according to the shape of the product 2 and placed in the base 1, the product 2 is loaded into the base 1 and placed at the center of the pad 4, and the position of the ball heads 32 in the multiple clamps 3 is adjusted by rotation so that each ball head 32 is pressed against the surface of the product 2, thereby completing the fixation of special-shaped products and small-sized products. Next, the product can be subjected to performance tests in terms of paint adhesion, paint hardness, and high-pressure water washing, which can ensure the flatness of the test surface and the accuracy of the test results.

[0042] The fixing device of the product provided by the present invention can effectively fix special-shaped structures and small-sized painted parts, facilitate performance testing of the product, accurately verify the paint performance of related parts, and avoid performance risks.
