[0033] The technical solution of the present invention will be described in detail below with reference to the attached drawings and embodiments.

[0034] As Figures 1-4 shown, an adjustable clamping device for machining automotive parts in this embodiment includes a base 1 and two clamping mechanisms 2 provided on the base 1. Both of the two clamping mechanisms 2 include a lateral adjustment component 21, a longitudinal adjustment component 22, an angle adjustment component 23, and a clamping component 24 that are connected in sequence. The two clamping mechanisms 2 are arranged at intervals in the front - rear direction and are symmetrical to each other;

[0035] The lateral adjustment component 21 includes a moving seat 211 and a lateral driving member. The lateral driving member can drive the moving seat 211 to move in the left - right direction, and the lateral driving member is connected to the base 1;

[0036] The longitudinal adjustment component 22 includes a moving plate 221 and a longitudinal driving member connected to the moving seat 211. The longitudinal driving member can drive the moving plate 221 to move in the front - rear direction;

[0037] The angle adjustment assembly 23 includes a rotating disk 231, an extended mounting plate 232, and a first rotating motor 233. The first rotating motor 233 is fixedly connected to the moving plate 221. The rotating disk 231 is arranged on the upper side of the moving plate 221 in a rotatable manner. The extended mounting plate 232 is fixedly connected to the rotating disk 231. The clamping assembly 24 is connected to the extended mounting plate 232. The output shaft of the first rotating motor 233 can drive the rotating disk 231 to rotate so as to change the orientation angle of the clamping assembly 24.

[0038] Most of the contour edges of automotive parts are not regular, and the contour edges of a large number of automotive parts such as fenders, trunk lids, and front hoods of engine compartments have arcs and angles. The lateral adjustment assembly 21 can change the position of the moving seat 211, so that the moving seat 211 drives the longitudinal adjustment assembly 22, the angle adjustment assembly 23, and the clamping assembly 24 to move as a whole in the left - right direction. The distance between the two clamping assemblies 24 can be changed through the two longitudinal adjustment assemblies 22. The angle adjustment assembly 23 can rotate the rotating disk 231, and the rotating disk 231 drives the extended mounting plate 232 to rotate, so that the extended mounting plate 232 drives the clamping assembly 24 to rotate, thereby realizing the change of the orientation angle of the clamping assembly 24. Furthermore, the two clamping assemblies 24 can clamp automotive parts at different angles respectively. In summary, the two clamping mechanisms 2 can move the two clamping assemblies 24 to the designated positions and rotate them to the designated angles, and then clamp the automotive parts with errors, so as to perform detailed processing on the error parts of the automotive parts. This device has a good clamping effect, is applicable to various automotive parts with different sizes and different contour edges, improves the versatility of the device, and reduces the number of tooling for automotive part processing.

[0039] In this embodiment, a ball 234 is arranged at the bottom of the extended mounting plate 232, and an annular bead groove 2211 is arranged at the top of the moving plate 221. The ball 234 extends into the annular bead groove 2211. The upper surface of the moving plate 221 is a plane. The annular bead groove 2211 arranged on the upper surface of the moving plate 221 can cooperate with the ball 234 on the extended mounting plate 232, making the rotation of the first rotating motor 233 driving the rotating disk 231 and the extended mounting plate 232 more smooth. At the same time, the ball 234 can support the extended mounting plate 232, reduce the suspended size of the extended mounting plate 232, and improve the stability of the clamping assembly 24.

[0040] In this embodiment, the length direction of the extended mounting plate 232 is along the radial direction of the rotating disk 231. The head end of the extended mounting plate 232 is connected to the rotating disk 231, and the other end of the extended mounting plate 232 is connected to the clamping assembly 24. The rotation of the rotating disk 231 can make the extended mounting plate 232 rotate, thereby changing the orientation angle of the clamping assembly 24.

[0041] In this embodiment, the clamping assembly 24 includes a clamping frame 241 and two clamping members. The two clamping members are arranged at intervals in the left-right direction and are symmetric to each other. Each of the two clamping members includes an electric push rod 242 connected to the clamping frame 241 and a clamping plate 243 connected to the electric push rod 242. The two clamping plates 243 face each other, and the two electric push rods 242 can drive the two clamping plates 243 to approach or move away from each other. The clamping frame 241 is connected to the extension mounting plate 232. The movement of the clamping frame 241 can drive the two clamping members to move together, so as to realize that the two electric push rods 242 drive the two clamping plates 243 to approach or move away from each other. Rubber pads are arranged on the facing surfaces of the two clamping plates 243.

[0042] In this embodiment, the lateral driving member includes a second rotating motor 212, a reciprocating lead screw 213, a guiding member, and two fixing plates 216. The two fixing plates 216 are fixedly arranged at intervals in the left-right direction on the base 1. The second rotating motor 212 is fixedly connected to one of the fixing plates 216. The reciprocating lead screw 213 is in transmission connection with the second rotating motor 212. The two ends of the reciprocating lead screw 213 are respectively rotatably connected to the two fixing plates 216. A threaded hole is arranged inside the moving seat 211, and the reciprocating lead screw 213 is in threaded cooperation with the threaded hole. The guiding member is connected to the moving seat 211, and the guiding member can enable the moving seat 211 to have only a single degree of freedom of moving in the left-right direction. The guiding member prevents the moving seat 211 from rotating, so that the moving seat 211 and the reciprocating lead screw 213 form a lead screw-nut pair. The axis of the reciprocating lead screw 213 is along the left-right direction. When the second rotating motor 212 drives the reciprocating lead screw 213 to rotate, the moving seat 211 can be moved in the left-right direction.

[0043] In this embodiment, the guiding member includes a guiding block 214 and a guiding rail 215. The guiding block 214 is fixedly connected to the moving seat 211, and the guiding rail 215 is fixedly connected to the base 1.

In this embodiment, the cross section of the guiding block 214 is in a "convex" shape. The guiding rail 215 is provided with a guiding groove for accommodating the guiding block 214 and a limiting protrusion for preventing the guiding block 214 from coming out. The cooperation between the guiding block 214 and the guiding rail 215 can ensure that the moving seat 211 has only a single degree of freedom of moving in the left-right direction.

[0044] In this embodiment, the longitudinal driving members of the two clamping mechanisms 2 are respectively arranged on the opposite sides of the moving seats 211 of the two clamping mechanisms 2, and the guiding members of the two clamping mechanisms 2 are respectively arranged on the opposite sides of the moving seats 211 of the two clamping mechanisms 2. The positions of the longitudinal driving members and the guiding members are reasonably set to prevent the guiding members from interfering with the clamped automotive parts.

[0045] In this embodiment, the longitudinal driving member includes an electric telescopic rod 222, a guiding sleeve 223 and a guiding rod 224; one end of the electric telescopic rod 222 is fixedly connected to the moving seat 211, and the other end of the electric telescopic rod 222 is fixedly connected to the moving plate 221; one end of the guiding sleeve 223 is fixedly connected to the moving seat 211, the other end of the guiding sleeve 223 is inserted and slidably engaged with the guiding rod 224, and the end of the guiding rod 224 away from the guiding sleeve 223 is fixedly connected to the moving plate 221. The electric telescopic rod 222 can move together with the moving seat 211. At the same time, the telescopic movement of the electric telescopic rod 222 can make the moving plate 221 move in the front-back direction, and the cooperation between the guiding sleeve 223 and the guiding rod 224 can ensure the accurate movement direction of the moving plate 221.
