Detailed Implementation

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model. Example

[0018] A multi-specification automotive parts clamping device includes a base 1, an outer movable ring 2, an inner movable ring 3, and a clamping assembly 4; the base 1 is provided with an outer ring groove 1-1 and an inner ring groove 1-2 for embedding the outer movable ring 2 and the inner movable ring 3 respectively, and the outer ring groove 1-1 and the inner ring groove 1-2 are concentric.

[0019] Limiting grooves are provided on the side walls of the outer ring groove 1-1 and the inner ring groove 1-2, and limiting structures embedded in the limiting grooves are provided on the outer movable ring 2 and the inner movable ring 3.

[0020] The outer movable ring 2 and the inner movable ring 3 are respectively provided with a number of outer ring mounting holes 2-1 and inner ring mounting holes 3-1 for installing the clamping assembly 4.

[0021] The clamping assembly 4 includes a clamping base 4-1, a clamping plate 4-2, a connector 4-3, a nut 4-4, a screw 4-5, and a horn nut 4-6; there are two clamping plates 4-2, which are mirror images of each other. The clamping plates 4-2 are provided with sliding grooves. The two ends of the clamping base 4-1 pass through the sliding grooves of the two clamping plates 4-2 respectively. The lower part of the clamping base 4-1 is provided with a mounting pin.

[0022] The upper part of connector 4-3 is a fastening threaded sleeve, and the lower part of connector 4-3 is a bolt. Nut 4-4 is first pre-fitted onto the fastening threaded sleeve on the upper part of connector 4-3. Then, the mounting pin at the lower part of clamp 4-1 is inserted into the fastening threaded sleeve on the upper part of connector 4-3, and nut 4-4 is tightened to fasten connector 4-3 and clamp 4-1.

[0023] Both the outer ring mounting hole 2-1 and the inner ring mounting hole 3-1 are threaded holes, and the bolts at the bottom of the connector 4-3 are threaded to both the outer ring mounting hole 2-1 and the inner ring mounting hole 3-1.

[0024] Two clamping plates 4-2 have corresponding through holes. The two ends of the screw 4-5 pass through the through holes of the two clamping plates 4-2 respectively. The horn nuts 4-6 are screwed into the two ends of the screw 4-5 so that the two clamping plates 4-2 clamp the car parts.

[0025] On the base 1, there are mounting holes for fixing plates located at the center of the outer movable ring 2 and the inner movable ring 3. There are two fixing plates 5, which are used to lock the outer movable ring 2 and the inner movable ring 3 respectively. The fixing plates 5 have locking protrusions 5-1 at both ends. The outer movable ring 2 and the inner movable ring 3 are respectively provided with outer locking holes 2-2 and inner locking holes 3-2. The fixing plates 5 have a through hole in the center. The fixing plates 5 are fixed to the base 1 by fastening bolts 6. The locking protrusions 5-1 of the fixing plates 5 are embedded in the outer locking holes 2-2 or the inner locking holes 3-2.

[0026] When in use, the clamping assembly 4 is installed according to the structural characteristics of the automotive parts. For example, when clamping crank parts, method one can be used:

[0027] Two clamping components 4 are simultaneously fixed on the outer movable ring 2 or the inner movable ring 3. The angle between the line connecting the selected outer ring mounting hole 2-1 (or inner ring mounting hole 3-1) and the mounting hole of the fixed plate of the two clamping components 4 matches the angle at the bend of the crank part.

[0028] Alternatively, method two can be used:

[0029] The two clamping components 4 are fixed on the outer movable ring 2 and the inner movable ring 3 respectively. The outer movable ring 2 or the inner movable ring 3 is rotated so that the two clamping components 4 meet the clamping requirements of the crank parts.

[0030] For example, when clamping straight pipe parts, the clamping component 4 on the outer movable ring 2 or the inner movable ring 3 can be selected according to the length of the straight pipe part.

[0031] For example, if the clamped part has a branch pipe, the number of clamping components 4 can be increased or decreased as appropriate.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
