Description

Technical Field

[0001] This utility model relates to the technical field of clamping structures, and in particular to a three-way clamping structure for a gauge. Background Technology

[0002] In the inspection of automotive interior pillars, it is common to find that one pillar completely encloses another. Currently, many interior parts have hook-and-loop structures with angled joints at the overlapping points. Using traditional clamping structures makes it difficult to insert and remove them, especially for parts with complex clamping joints that need to be reused. This not only leads to poor repeatability in the process, but also results in a lot of cost waste. Utility Model Content

[0003] The purpose of this invention is to provide a three-way clamping structure for a gauge to solve the problems mentioned in the background art.

[0004] The technical solution adopted in this utility model is:

[0005] A three-way clamping structure for a gauge includes: a gauge mounting transition plate with a simulated block 1 fixedly connected to its bottom; a slide rod fixedly connected to one side of the simulated block 1; a limiting block disposed at one end of the slide rod; a simulated block 2 slidably connected to the slide rod; a clamping simulated insert disposed at the bottom of the simulated block 1 and one side of the simulated block 2; a threaded rod 1 rotatably connected to one side of the simulated block 1, and the threaded rod 1 passes through the simulated block 2 and is threadedly connected to the simulated block 2; and a handle fixedly connected to the outer end of the threaded rod 1.

[0006] Optionally, the slide bar and the limiting block are a set, and multiple sets are provided on the simulation block.

[0007] Optionally, one end of the slide bar is rotatably connected to the simulation block via a linear bearing.

[0008] Optionally, an elastic washer is provided on the inner side of the simulation block.

[0009] Optionally, a connecting rod is rotatably connected inside the simulation block one, and slots are provided at both ends of the connecting rod. A sliding groove is provided inside the simulation block one, and a threaded rod two is rotatably connected inside the sliding groove. One end of the threaded rod two passes through the handle and is rotatably connected to the handle. A locking block two is slidably connected inside the sliding groove, and the other end of the threaded rod two is inserted into the locking block two and threadedly connected to the locking block two.

[0010] Optionally, the second cross section of the card block is a regular polygon.

[0011] Optionally, a set bolt is threaded onto the handle, and one end of the set bolt is inserted into the threaded rod.

[0012] Optionally, the thread length on the second threaded rod is less than half the length of the second threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In use, the corresponding detection part is placed inside simulation block one and simulation block two, and after they are aligned, the handle is rotated to bring the two simulation blocks two closer together. The sliding rod restricts the simulation blocks two to slide only laterally. Then, the inclined surface on the inner side of simulation block two contacts the part, thereby clamping the part, thus achieving... Figure 2 The working state enables the same mechanism to clamp and position different parts, solving the problem that existing clamping structures are not easy to insert and remove parts, especially for parts with complex clamping and repeated use. This not only leads to poor repeatability in the process, but also to a lot of cost waste. Attached Figure Description

[0023] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Given that the traditional clamping structure is not easy to insert and remove parts in the current technology, especially for parts with complex clamping and that need to be reused, it not only leads to poor repeatability in the process, but also results in a lot of cost waste.

[0026] like Figure 1-3 As shown, this utility model embodiment provides a three-way clamping structure for a gauge, including: a gauge mounting transition plate 10 with a simulated block 11 fixedly connected to its bottom; a slide rod 20 fixedly connected to one side of the simulated block 11; a limiting block 21 disposed at one end of the slide rod 20; a simulated block 22 slidably connected to the slide rod 20; a clamping simulated insert 23 disposed at the bottom of the simulated block 11 and one side of the simulated block 22; a threaded rod 24 rotatably connected to one side of the simulated block 11, and the threaded rod 24 passes through the simulated block 22 and is threadedly connected to the simulated block 22; and a handle 25 fixedly connected to the outer end of the threaded rod 24.

[0027] Before use, first install the slide bar 20 on one side of the simulation block 11. Then, after installing the threaded rod 24 and the simulation block 22, fix the fixture mounting transition plate 10 onto the designated fixture. Figure 1 The image shows the state of this application when it is not in operation. Figure 2 The image shown depicts the working state of this application. Figure 1In the non-working state, place the corresponding detection part inside simulation block 11 and simulation block 22, and after they are in contact, rotate handle 25 to drive threaded rod 24 to rotate on one side of simulation block 11. Simultaneously, through the threaded connection with simulation block 22, the two simulation blocks 22 are brought closer together. Slide rod 20 restricts simulation block 22 to slide only laterally. Then, the inclined surface inside simulation block 22 contacts the part, clamping the part, thereby achieving... Figure 2 The working state enables the same mechanism to clamp and position different parts.

[0028] Specifically, both simulation block 11 and simulation block 22 are made in the form of real vehicle parts. During installation, simulation blocks 22 are first moved away from each other so that the parts can be installed on simulation block 11 without obstruction. Then, the two simulation blocks 22 are brought closer together to clamp the parts.

[0029] Furthermore, the slide bar 20 and the limiting block 21 are a set, and multiple sets are provided on the simulation block 11, making the sliding of the simulation block 22 more stable.

[0030] Furthermore, one end of the slide rod 20 is rotatably connected to the simulation block 11 via a linear bearing. During installation, the linear bearing is embedded in the simulation block 22, and then the slide rod 20 is connected to the linear bearing to achieve the installation of the slide rod.

[0031] Furthermore, a connecting rod 30 is rotatably connected within the simulation block 11. The connecting rod 30 has slots 31 at both ends. A sliding groove 32 is provided within the simulation block 11. A threaded rod 33 is rotatably connected within the sliding groove 32. One end of the threaded rod 33 passes through the handle 25 and is rotatably connected to the handle 25. A locking block 34 is slidably connected within the sliding groove 32. The other end of the threaded rod 33 is inserted into the locking block 34 and is threadedly connected to the locking block 34.

[0032] Before clamping the parts, first rotate the threaded rod 33 to make the locking block 34 slide in the two grooves 32. Then, insert the two locking blocks 34 into the two slots 31 respectively. After connecting the connecting rod 30 with the locking blocks 34 and the threaded rod 33, when rotating any one of the threaded rods 24, the other threaded rod 24 will rotate synchronously through the transmission of the locking blocks 34 and the connecting rod 30, thereby improving the clamping efficiency.

[0033] Furthermore, the cross-section of the second card block 34 is a regular polygon, which facilitates the insertion of the second card block 34 into the card slot 31.

[0034] Furthermore, a set bolt is threaded onto the handle 25, and one end of the set bolt is inserted into the threaded rod 33. When the locking block 34 is inserted into the slot 31, the set bolt is rotated so that one end of the set bolt is inserted into the threaded rod 33, thereby locking the threaded rod 33 with the handle 25. When the handle 25 is rotated, the threaded rod 33 is driven to rotate synchronously.

[0035] Furthermore, the thread length on the second threaded rod 33 is less than half the length of the second threaded rod 33, so that the thread on the second threaded rod 33 contacts the first threaded rod 24.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
