[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The present invention provides a technical solution: a high-precision control arm size detection device, comprising a base 1, a control arm body 3, and a fixing plate 2 fixedly connected to the top of the base 1. An adjustment component 4 is movably installed on the top outer wall of the front side of the base 1. Fixing components 5 are fixedly installed on the front side of the fixing plate 2 and the inner side of the adjustment component 4. A positioning block 6, a bushing gauge block 1 7, a bushing gauge block 2 8, and a ball head gauge block 9 are movably installed on the front side of the fixing component 5. The control arm body 3 is movably engaged with the outer front side of the positioning block 6, the bushing gauge block 1 7, the bushing gauge block 2 8, and the ball head gauge block 9.

[0025] The adjustment component 4 includes a guide frame 41, which is fixedly installed on the top right end of the rear side of the fixing plate 2. The guide frame 41 has an installation groove 42 inside, and an adjustment screw 43 is rotatably installed inside the installation groove 42. The right end of the adjustment screw 43 extends to the outside of the guide frame 41 and is fixedly installed with a handwheel 44. A sliding block 45 is threadedly connected to the outside of the adjustment screw 43. The sliding block 45 is limited and slidably disposed inside the installation groove 42. The front end of the sliding block 45 slides through the fixing plate 2 and is fixedly installed with an installation plate 46. The fixing component 5 is disposed on the inner side of the installation plate 46.

[0026] In use, the control arm body 3 is installed on the front side of the fixing plate 2 according to the positions of the positioning block 6, bushing gauge block 7, and ball head gauge block 9. By turning the handwheel 44, the adjusting screw 43 can be rotated. The rotation of the adjusting screw 43 drives the sliding block 45 to slide along the mounting groove 42. The sliding block 45 drives the mounting plate 46 and the inner bushing gauge block 8 to slide, so that the bushing gauge block 8 is engaged in the corresponding small bushing hole of the control arm body 3. Turning the handwheel 44 in the opposite direction can drive the bushing gauge block 8 to move outward and disassemble, thereby facilitating the disassembly and assembly of the control arm body 3 and improving testing efficiency.

[0027] Preferably, the fixed plate 2 has a through-hole corresponding to the sliding block 45. The front end of the sliding block 45 slides through the through-hole, which can ensure that the sliding block 45 moves smoothly and steadily under the drive of the adjusting screw 43. The through-hole also plays a certain role in limiting the sliding block 45, preventing it from deviating or shaking during movement, thereby ensuring the stability and accuracy of the entire adjustment process.

[0028] Preferably, the handwheel 44 is located on the outer side of the right end face of the fixed plate 2, and the outer side of the sliding block 45 is provided with anti-slip texture to increase the friction during rotation, so that the user can operate more easily and stably when turning the handwheel 44, avoid slipping and causing adjustment errors, and further improve the accuracy and reliability of the entire detection device.

[0029] Please see Figure 4 and Figure 5In some embodiments, the fixing component 5 includes a docking sleeve 51. The inner front side wall of the docking sleeve 51 is provided with a rotating groove 52. The front side of the docking sleeve 51 is provided with two openings 53 that communicate with the rotating groove 52. A plug 54 is movably engaged inside the rotating groove 52. Two limiting pieces 55 corresponding to the openings 53 are fixedly connected to the outer side wall of the front end of the plug 54. The limiting pieces 55 can be engaged inside the rotating groove 52. A threaded hole 56 is provided on the front end face of the plug 54.

[0030] In use, the insert 54 is inserted into the inside of the mating sleeve 51, and the limiting piece 55 is inserted into the rotating slot 52 from the opening 53. Then, by rotating the insert 54, the limiting piece 55 is rotated in the rotating slot 52 and offset from the position of the opening 53. The insert 54 is fixed by the limiting piece 55 being locked in the rotating slot 52.

[0031] Preferably, the rear end faces of the positioning block 6, bushing gauge block 7, and ball head gauge block 9 are all fixedly connected with threaded rods 57 that are adapted to the threaded holes 56. The threaded rods 57 are screwed and fixed to the threaded holes 56, thereby facilitating the quick assembly and disassembly of the insert 54 without the need for tools, and improving the ease of use.

[0032] Preferably, the two openings 53 and the two limiting pieces 55 are symmetrically arranged. When the insertion post 54 is connected and engaged with the mating sleeve 51, each part can bear the external force relatively evenly, effectively reducing the risk of local wear or damage due to uneven force distribution, and maintaining good connection stability at all times, further improving the overall practicality and durability of the component.

[0033] Please see Figure 2 In some embodiments, multiple mating sleeves 51 are installed on the front side of the fixing plate 2 at positions corresponding to the positioning block 6, bushing block 1 7, and bushing block 2 8. Multiple mating sleeves 51 are installed on the mounting plate 46. Through holes corresponding to the insertion post 54 are provided on the front side of the fixing plate 2 and inside the mounting plate 46, so that the insertion post 54 can pass through smoothly and be fixed therein, thereby improving stability. By setting multiple fixing components 5, they can be set according to the specifications and models of the control arm body 3 and can be adjusted to improve applicability.

[0034] Working principle: By adjusting the position of the fixing component 5 according to the specifications of the control arm body 3, the insertion post 54 is inserted into the inside of the docking sleeve 51, and the limiting piece 55 is inserted into the rotating slot 52 from the opening 53. Then, by rotating the insertion post 54, the limiting piece 55 is rotated in the rotating slot 52 and offset from the position of the opening 53. The insertion post 54 is fixed by the limiting piece 55 in the rotating slot 52. Then, the positioning block 6 with the threaded rod 57 at the rear end, the bushing measuring block 1 7, the ball head measuring block 9 are screwed and fixed to the corresponding threaded holes 56. The bushing measuring block 2 8 is screwed and fixed on the threaded hole 56 on the inner side of the mounting plate 46 using the threaded rod 57.

[0035] Then, the control arm body 3 is installed on the front side of the fixing plate 2 according to the positions of the positioning block 6, bushing gauge block 7, and ball head gauge block 9. By rotating the handwheel 44, the adjusting screw 43 can be rotated. The rotation of the adjusting screw 43 drives the sliding block 45 to slide along the mounting groove 42. The sliding block 45 drives the mounting plate 46 and the inner bushing gauge block 8 to slide, so that the bushing gauge block 8 is engaged in the corresponding small bushing hole of the control arm body 3. If the control arm body 3 can be installed in front of the fixing plate 2 and the positioning block 6, bushing gauge block 7, bushing gauge block 8, and ball head gauge block 9 can all be engaged in the corresponding holes, then the size of the control arm body 3 is qualified; otherwise, the size of the control arm body 3 is unqualified. After testing one control arm body 3, by rotating the handwheel 44 in the opposite direction, the sliding block 45 can be driven to slide outward along the mounting groove 42, causing the bushing gauge block 8 to move outward and disengage from the control arm body 3, so that the control arm body 3 can be easily replaced for testing. The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
