SPECIFIC IMPLEMENTATION

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] like Figures 1-6 As shown, the present invention proposes a fixing structure for automobile tire bolts, which mainly includes a mounting housing 1. A top rod 2 is fixedly installed on the top of the mounting housing 1. A fixing platform 3 is fixedly connected to the top of the top rod 2. A placement groove 31 is machined on the top of the fixing platform 3 for placing the object to be processed. Sliding grooves 30 are opened on all four sides of the platform. Multiple sliding clamps 6 are movably arranged in the fixing platform 3. These sliding clamps 6 are located in the corresponding sliding grooves 30 and can slide freely in the grooves to achieve the clamping action of the object.

[0023] The mounting housing 1 is equipped with a drive assembly for driving the movement of the sliding clamp 6. The drive assembly includes a telescopic cylinder 40. The top of the telescopic rod of the telescopic cylinder 40 is fixedly connected to a support frame 41. Multiple arms of the support frame 41 pass through the top plate of the mounting housing 1, and a cross top plate 42 is fixedly fixed at the top of the arms of the support frame 41. A sliding sleeve 43 is installed in the middle of the cross top plate 42. The sliding sleeve 43 can slide freely on the top rod 2 to ensure the stability and verticality of the cross top plate 42 during the up and down movement. Multiple inclined guide plates 44 are fixed on the cross top plate 42, and a first slide rail 45 is installed on the front of each inclined guide plate 44.

[0024] The sliding clamp 6 has a second sliding groove 61 at its tail end. The first slide rail 45 is embedded in the second sliding groove 61, so that the inclined guide plate 44 and the sliding clamp 6 form an effective transmission connection. When the inclined guide plate 44 moves up and down, it can drive the sliding clamp 6 to slide left and right in the sliding groove 30. The top of the sliding clamp 6 is fixed with a clamp 62 for direct contact and fixing of objects. In order to further ensure the smooth movement of the sliding clamp 6, the first sliding groove 60 is symmetrically arranged on both sides of the sliding clamp 6. At the same time, the second slide rail 5 is fixed on the inner wall of both sides of each sliding groove 30. The second slide rail 5 is embedded in the first sliding groove 60, realizing a stable sliding connection between the sliding clamp 6 and the fixed platform 3.

[0025] In addition, to prevent the chucks 62 from damaging the object when clamping it, each chuck 62 has a rubber pad 63 attached to its front side, which can increase the friction of clamping and protect the surface of the object from scratches.

[0026] In the device starting stage, first need to put bolt accurate placement in the placement slot 31, immediately start telescopic cylinder 40, telescopic cylinder 40 quickly responds and eject telescopic rod, the thrust generated by this action directly acts on support frame 41, drive support frame 41 moves upward, along with the rise of support frame 41, the cross top plate 42 connected therewith also synchronously lifts, this linkage process makes several inclined guide plates 44 begin to move upward, because of the structural design between inclined guide plate 44 and sliding clamp plate 6, in the process of inclined guide plate 44 moving upward, will generate an inward component force, thereby push several sliding clamp plate 6 in the respective sliding slot 30 simultaneously slide smoothly to the inside, when several chuck 62 tight contact and firmly hold the bolt, it means that the bolt has been accurately positioned and fixed, at this time should immediately stop the operation of telescopic cylinder 40, to maintain the current stable clamping state, in turn ensure that the bolt does not shift or loosen in the subsequent process of processing the bolt, guarantee the precision and quality of processing.

[0027] It should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present application shall be included within the scope of protection of the present application. In addition, the claims of the present application are intended to cover all changes and modifications falling within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
