[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0034] Please refer to Figures 1 to 4 , and now the clamp for vehicle maintenance provided by the present utility model will be described. The clamp for vehicle maintenance includes a bottom tube 10, a first screw 20, a first clamping assembly 30, and a second clamping assembly 40. A strip-shaped chute 11 is provided at the top of the bottom tube 10, and the extending direction of the chute 11 is parallel to the axial direction of the bottom tube 10; the first screw 20 is rotatably connected to the bottom tube 10; the first clamping assembly 30 is fixedly connected to one end of the bottom tube 10. The first clamping assembly 30 has a first fixing plate 31 located above the bottom tube 10 and a plurality of first clamping blocks 32 connected to the first fixing plate 31. The plurality of first clamping blocks 32 are arranged in sequence along a first preset path, and the first preset path is parallel to the horizontal direction and perpendicular to the axial direction of the bottom tube 10; the second clamping assembly 40 includes a first nut 41 threadedly engaged with the first screw 20, a sliding sleeve 42 connected to the first nut 41, a second fixing plate 43 fixedly connected to the sliding sleeve 42, and a plurality of second clamping blocks 44 connected to the second fixing plate 43. The plurality of second clamping blocks 44 are arranged in sequence along the first preset path and are disposed opposite to the plurality of first clamping blocks 32; wherein, the first clamping block 32 can move in a direction close to or away from the first fixing plate 31, and the second clamping block 44 can move in a direction close to or away from the second fixing plate 43.

[0035] In specific implementation, the bottom of the first fixing plate 31 is inclined in a direction away from the second fixing plate 43, and the bottom of the second fixing plate 43 is inclined in a direction away from the first fixing plate 31. That is, the interval between the bottoms of the first fixing plate 31 and the second fixing plate 43 is larger than the interval at the top, which can facilitate the insertion of parts and avoid friction between the parts and the first fixing plate 31 and the second fixing plate 43 after the first clamping block 32 and the second clamping block 44 clamp the parts.

[0036] In order to protect the outer surface quality of the parts, rubber layers can be provided on the opposite surfaces of the first clamping block 32 and the second clamping block 44.

[0037] Compared with the prior art, when the clamp for vehicle maintenance provided in this embodiment is in use, by rotating the first screw 20, the second clamping assembly 40 can be driven to move reciprocally along the axial direction of the bottom tube 10, so as to adjust the distance between the first clamping assembly 30 and the second clamping assembly 40. After roughly clamping the parts, by adjusting the movement of the plurality of first clamping blocks 32 and the plurality of second clamping blocks 44, the plurality of first clamping blocks 32 can be adapted to the outer surface of the parts, and the same applies to the plurality of second clamping blocks 44. The clamp for vehicle maintenance of the present utility model can be applicable to the processing and clamping of various parts, has a wide application range, and has good clamping stability for parts with different shapes, avoiding frequent adjustment during the processing and improving work efficiency.

[0038] In some embodiments, a specific adjustment method for the above-mentioned first clamping block 32 and second clamping block 44 can be as follows Figures 1 to 3The structure shown. Refer to Figures 1 to 3 , both the first clamping assembly 30 and the second clamping assembly 40 include an adjusting mechanism. The adjusting mechanism includes a second nut 50 and a bolt 51. The second nut 50 is fixedly connected to the first fixing plate 31 or the second fixing plate 43; the bolt 51 is threadedly connected to the second nut 50, and the end of the bolt 51 is rotatably connected to the first clamping block 32 or the second clamping block 44. The bolt 51 is used to drive the first clamping block 32 and the second clamping block 44 to move. By cooperating the bolt 51 with the second nut 50, the bolt 51 can be rotated. When the bolt 51 rotates, the distance between its end and the first fixing plate 31 or the second fixing plate 43 changes. The bolt 51 corresponding to the first clamping block 32 drives it to reciprocate, and the bolt 51 corresponding to the second clamping block 44 drives it to reciprocate, realizing the separate adjustment of multiple first clamping blocks 32 and multiple second clamping blocks 44, which is convenient to use.

[0039] It is easy to understand that when the bolt 51 rotates, the relative position between the bolt 51 and the first clamping block 32 does not change, and the bolt 51 only drives the first clamping block 32 to move. The specific structure can be: a limiting sleeve is fixed at the end of the bolt 51, a cylindrical cavity for accommodating the limiting sleeve is provided in the first clamping block 32, and the accommodating cavity communicates with the outside through a through hole. The end of the bolt 51 passes through the through hole, and the limiting sleeve is located in the cylindrical cavity. Since the diameter of the through hole is smaller than that of the cylindrical cavity, when the bolt 51 rotates, the limiting sleeve rotates in cooperation with the cylindrical cavity, and the bolt 51 will not rotate out of the first clamping block 32; the same applies to the second clamping block 44.

[0040] In some embodiments, an improved implementation manner of the above adjusting mechanism can adopt the structure as shown in Figure 3 The structure shown. Refer to Figure 3 , a plurality of gaskets 52 are provided on the outer periphery of the bolt 51, and the gaskets 52 are located between the first clamping block 32 and the first fixing plate 31 or between the second clamping block 44 and the second fixing plate 43. When there is a gap between the first clamping block 32 and the first fixing plate 31, the gasket 52 is located between the first clamping block 32 and the first fixing plate 31, which can make the process of clamping parts more stable and avoid the shaking of the first clamping block 32; the same applies to the second clamping block 44.

[0041] When the gasket 52 is not applicable, the gasket 52 can be placed between the head of the bolt 51 and the first fixing plate 31 for convenient storage; the same applies to the bolt 51 on the second fixing plate 43.

[0042] In some embodiments, an improved implementation manner of the above gasket 52 can adopt the structure as shown in Figure 4 The structure shown. Refer to Figure 4, a semi-circular or semi-elliptical limiting groove 53 is formed by the depression on the bottom surface of the gasket 52, and the limiting groove 53 cooperates with the bolt 51. Although the gasket 52 can be clamped and fixed by the first clamping block 32 and the first fixing plate 31, the provision of the limiting groove 53 facilitates the placement of the gasket 52.

[0043] In some embodiments, a specific implementation of the above-mentioned first clamping block 32 and second clamping block 44 may adopt the structure as Figures 1 to 3 shown. Refer to Figures 1 to 3 , there are three first clamping blocks 32 and second clamping blocks 44 respectively, and a threaded through hole 60 for the bolt 51 to penetrate is provided on the middle first clamping block 32 or second clamping block 44. A threaded through hole 60 is alternatively provided on the middle first clamping block 32 and the middle second clamping block 44. Here, taking the middle first clamping block 32 being provided with the threaded through hole 60 as an example for illustration, in this embodiment, the bolt 51 and the first clamping block 32 do not adopt the above-mentioned limiting sleeve and cylindrical cavity structure. The bolt 51 can drive the first clamping block 32 to move, or the bolt 51 can be rotated out of the threaded through hole 60 of the first clamping block 32. When the bolt 51 protrudes from the first clamping block 32, it can be adapted to a part with a middle hole. Then, when clamping the part, the protruding bolt 51 cooperates with the middle hole of the part, and the clamping stability is higher.

[0044] In some embodiments, an improved implementation of the above-mentioned sliding sleeve 42 may adopt the structure as Figures 1 to 3 shown. Refer to Figures 1 to 3 , support plates 45 are provided on both opposite sides of the bottom of the sliding sleeve 42, and legs 33 are provided at the bottom of the first fixing plate 31. The support plates 45 and the legs 33 cooperate to form a support system, which facilitates the placement of the vehicle repair fixture of the present application on a tabletop or other positions to process parts.

[0045] Specifically, a second screw rod is in threaded cooperation with the first fixing plate 31. The second screw rod is parallel to the up-down direction, and the second screw rod forms the legs 33. The second screw rod can be adjusted up and down by screwing, and thus the height can be adjusted according to different working environments.

[0046] In some embodiments, an improved implementation of the above-mentioned second clamping assembly 40 may adopt the structure as Figure 1 shown. Refer to Figure 1 , the second clamping assembly 40 further includes a reinforcing plate 46 connected between the second fixing plate 43 and the sliding sleeve 42. The reinforcing plate 46, the second fixing plate 43 and the top plate of the sliding sleeve 42 enclose a triangular structure, which has higher structural strength, greater clamping force and higher clamping stability for the part.

[0047] Similarly, a reinforcing plate 46 may also be provided between the first fixing plate 31 and the bottom tube 10.

[0048] In some embodiments, an improved implementation of the above-mentioned first screw 20 may adopt the structure as shown in Figures 1 to 3 . Refer to Figures 1 to 3 . One end of the first screw 20 extends out of the bottom pipe 10 and is inserted with an operating rod 21, and the operating rod 21 is perpendicular to the first screw 20. By rotating the operating rod 21 to drive the first screw 20 to rotate, it is convenient to operate and reduces the labor intensity; the operating rod 21 is inserted and matched with the first screw 20, which is convenient to remove the operating rod 21 during the working process to avoid accidentally hitting the operator.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
