Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts testing technology, and in particular to a clamping structure for a testing fixture. Background Technology
[0002] With declining profits in the automotive market and an increase in existing projects in factories, fixtures must also consider cost reduction and miniaturization. The original door frame trim fixtures used standard clamps to clamp and position the trim products assembled on the fixtures. However, standard clamps are large and take up a lot of space. Due to this structure, the fixture base plate also has to be enlarged (for safety reasons, the clamps cannot extend beyond the fixture base plate). This makes it impossible to further optimize manufacturing costs and miniaturization. Utility Model Content
[0003] This application aims to solve one of the aforementioned technical problems in the prior art. To this end, embodiments of this application provide a clamping structure for a gauge.
[0004] According to an embodiment of this application, a clamping structure for a gauge is provided, including a mounting base, wherein a positioning part is provided on the mounting base, and the positioning part is formed with a contour groove for positioning a door frame trim strip;
[0005] A clamping member is disposed on the mounting base and extends from one end of the positioning part to the other end. Several sets of clamping members are spaced apart and close to the contour groove. The clamping member includes a pre-pressing member, an adjustment structure, and a mounting base. The pre-pressing member is rotatably disposed on the mounting base. One end of the pre-pressing member can rotate to the top of the contour groove. The end of the pre-pressing member has a tendency to move toward the contour groove under the action of the adjustment structure.
[0006] The clamping structure of the aforementioned fixture has at least the following beneficial effects: During use, when loading or removing the door frame trim into or from the contour slot, the pre-compression member is rotated to a position away from the contour slot to avoid affecting the loading and unloading of the door frame trim. When it is necessary to clamp the door frame trim in the contour slot, the pre-compression member is rotated to a position above the contour slot. The pre-pressure provided by the adjustment structure drives the pre-compression member towards the contour slot to clamp the door frame trim into the contour slot. Multiple clamping components ensure a more secure clamping of the door frame trim, facilitating subsequent inspection. Compared to using standard clamps to clamp the door frame trim, the clamping component structure of this application is simpler and easier to operate. During use, it will not exceed the mounting base (equivalent to the fixture base plate) and will not occupy excessive structural space.
[0007] According to the clamping structure of the inspection fixture described in the embodiments of this application, the mounting base is provided with a positioning groove. When the pre-pressing member rotates to the positioning groove, the end of the pre-pressing member presses against the door frame trim placed in the positioning groove.
[0008] According to the clamping structure of the gauge described in the embodiments of this application, one end of the pre-compression member is rotatably mounted on the mounting base via a rotating shaft, and the other end of the pre-compression member is provided with a buffer portion.
[0009] According to the clamping structure of the gauge described in the embodiments of this application, the vertical distance between the buffer portion and the positioning groove is adjustable.
[0010] According to the clamping structure of the gauge described in the embodiments of this application, the buffer part includes a connecting post, and the connecting post is connected to the pre-compression member through a threaded structure.
[0011] According to the clamping structure of the inspection fixture described in the embodiments of this application, the buffer part is made of rubber, and one end of the connecting post is wrapped by the buffer part.
[0012] According to the clamping structure of the inspection fixture described in the embodiments of this application, one end of the rotating shaft is fixed to the positioning groove by a threaded structure, and the adjustment structure is disposed on the rotating shaft.
[0013] According to the clamping structure of the gauge described in the embodiments of this application, the adjusting structure includes an adjusting member and an elastic member. The adjusting member is sleeved on the rotating shaft, one end of the elastic member abuts against the rotating shaft, and the other end of the elastic member abuts against the adjusting member, so that the adjusting member presses against the pre-pressing member.
[0014] According to the clamping structure of the gauge described in the embodiments of this application, the adjusting member includes a first hole and a second hole. The first hole passes through both ends of the adjusting member, and the second hole forms a stepped hole with the first hole. The end of the rotating shaft is provided with a limiting part, which can slide in the second hole. The rotating shaft passes through the first hole, and the elastic member is disposed in the second hole.
[0015] According to the clamping structure of the gauge described in the embodiments of this application, the elastic element is sleeved on the rotating shaft, one end of the elastic element abuts against the limiting part, and the other end of the elastic element abuts against the bottom of the second hole.

[0028] Reference Figures 1 to 3This application provides a clamping structure for a gauge, which includes a mounting base 110 and a clamping member 200.
[0029] The mounting base 110 serves as the base plate for the inspection fixture, and all other components used for inspection and the positioning parts 120 are mounted on the mounting base 110. The mounting base 110 is provided with a positioning part 120, which has a contour groove 121 for positioning the door frame trim. The shape of the contour groove 121 is the same as the shape and size of the standard door frame trim. If the door frame trim to be inspected cannot be placed into the contour groove 121, then the door frame trim does not meet the requirements. If the door frame trim can be placed into the contour groove 121, then the other dimensions of the door frame trim need to be inspected. At the same time, the contour groove 121 plays a positioning role, and together with the clamping member 200, it can fix the door frame trim to be inspected so that the door frame trim will not loosen or move during the inspection process.
[0030] In this embodiment, multiple clamping members 200 are provided. These clamping members 200 are disposed on the mounting base 110, extending from one end of the positioning portion 120 to the other. Several groups of clamping members 200 are spaced apart and close to the contour groove 121, minimizing the structural space occupied by the clamping members 200 on the mounting base 110. Each clamping member 200 includes a pre-pressing member 220, an adjustment structure, and a mounting base 210. The pre-pressing member 220 is rotatably disposed on the mounting base 210. One end of the pre-pressing member 220 can rotate to above the contour groove 121, and the end of the pre-pressing member 220 tends to move towards the contour groove 121 under the action of the adjustment structure.
[0031] During use, if it is necessary to install the door frame trim into or remove it from the contour groove 121, such as Figure 3 As shown, the pre-compression member 220 is rotated to a position away from the contour groove 121 to avoid affecting the loading and unloading of the door frame trim. When it is necessary to compress the door frame trim in the contour groove 121, as follows: Figure 2 As shown, the pre-compression member 220 is rotated above the contour groove 121. The pre-compression member 220 is driven to move toward the contour groove 121 by adjusting the pre-pressure provided by the structure to press the door frame trim into the contour groove 121. The multiple sets of pressing members 200 make the pressing of the door frame trim more secure for subsequent testing.
[0032] Compared to using standard clamps to tighten door frame trim, the clamping member 200 of this application has a simpler structure and is easier to operate, such as... Figure 3 As shown, during use, it will not exceed the mounting base 110 (equivalent to the fixture base plate) and will not occupy too much structural space.
[0033] In some embodiments, such as Figure 3As shown, the mounting base 210 is provided with a positioning groove 211. When the pre-compression member 220 rotates to the positioning groove 211, the end of the pre-compression member 220 presses against the door frame trim placed in the positioning groove 211.
[0034] Specifically, the positioning groove 211 is located on the top surface of the mounting base 210. The width of the pre-compression member 220 is smaller than the width of the positioning groove 211. When it is not necessary to compress the door frame trim, the pre-compression member 220 is raised to the top surface of the mounting base 210 and rotated to a position above the contour groove 121 to prevent it from affecting the loading and unloading of the door frame trim. Due to the adjustment structure, the pre-compression member 220 will not automatically rotate into the positioning groove 211. The positioning groove 211 serves two purposes: firstly, it quickly positions the pre-compression member 220 in the compression position; secondly, it prevents mistaken insertion. If the pre-compression member 220 is not in the positioning groove 211, it is definitely not in the state of compressing the door frame trim on the contour groove 121.
[0035] In some embodiments, one end of the pre-compression member 220 is rotatably mounted on the mounting base 210 via a pivot 260, so that the pre-compression member 220 can rotate freely. Specifically, when the pre-compression member 220 is lifted up to leave the positioning groove 211, the pre-compression member 220 can rotate freely. The other end of the pre-compression member 220 is provided with a buffer part 230, which can prevent excessive pre-compression from damaging the surface of the door frame trim.
[0036] The vertical distance between the buffer section 230 and the positioning groove 211 is adjustable so as to accommodate the pressing of door frame trim strips of different thicknesses, or to adjust the pressing force in this way.
[0037] In some embodiments, the buffer portion 230 includes a connecting post 240, which is connected to the preload member 220 via a threaded structure. Specifically, the outer surface of the connecting post 240 is provided with external threads, and the preload member 220 is provided with a threaded hole that matches the external threads of the connecting post 240, so that the distance between the buffer portion 230 and the positioning groove 211 is adjustable by means of threads.
[0038] In some specific embodiments, the buffer portion 230 is made of rubber, and one end of the connecting post 240 is wrapped by the buffer portion 230. The buffer portion 230 is injection molded, and the connecting post 240 is integrally formed into the injection mold during the injection molding process.
[0039] In some embodiments, such as Figures 3 to 5 As shown, one end of the rotating shaft 260 is fixed to the positioning groove 211 by a threaded structure, so that the preloaded component 220 can rotate into the positioning groove 211. The adjustment structure is set on the rotating shaft 260, which effectively utilizes the existing structure and reduces the space occupied by the adjustment structure.
[0040] In some embodiments, the adjustment structure includes an adjustment member 250 and an elastic member 270. The adjustment member 250 is sleeved on the rotating shaft 260, one end of the elastic member 270 abuts against the rotating shaft 260, and the other end of the elastic member 270 abuts against the adjustment member 250, so that the adjustment member 250 presses against the pre-pressing member 220. The rotating shaft 260 guides the adjustment member 250, and the elastic force provided by the elastic member 270 acts on the adjustment member 250, so that the pre-pressing member 220 can press against the door frame trim strip in the contour groove 121 with a certain pre-pressure.
[0041] In some specific embodiments, the adjusting member 250 includes a first hole and a second hole. The first hole extends through both ends of the adjusting member 250, and the second hole forms a stepped hole 251 with the first hole. A limiting part is provided at the end of the rotating shaft 260, which can slide in the second hole. The rotating shaft 260 passes through the first hole, and the elastic member 270 is disposed in the second hole. The formation of the stepped hole 251 can limit the range of motion of the elastic member 270 with the limiting part, and can also guide the adjusting member 250.
[0042] In some specific embodiments, the elastic element 270 is a spring, the elastic element 270 is sleeved on the rotating shaft 260, one end of the elastic element 270 abuts against the limiting part, and the other end of the elastic element 270 abuts against the bottom of the second hole.
[0043] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
