[0004] The inventors believe that this solution has the following problems: 1. Car mold processing often requires processing multiple surfaces at different angles and positions. Traditional processing methods may require different equipment or multiple clamping operations; 2. Although there are protective pads on the clamping plate, the shock absorption effect is still poor. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a clamping device for automobile molds.

[0006] The clamping device for automobile molds provided by this utility model adopts the following technical solution:

[0007] A clamping device for automotive molds includes a drive base, a bracket, clamping assemblies, and a vertical rotation mechanism. The clamping assemblies are respectively mounted on the bracket, and the bracket is mounted on the drive base. The drive base drives the brackets to move closer or further apart. The drive base is fixed to the vertical rotation mechanism. The vertical rotation mechanism includes a reduction motor, a first worm gear, a first worm, a first bearing housing, a second bearing housing, and a connecting platform. The two ends of the connecting platform are rotatably connected between the first and second bearing housings. One end of the connecting platform passes through the first bearing housing, and the end of the connecting platform is connected to the first worm gear. The reduction motor is fixed to the outside of the first bearing housing, and the output end of the reduction motor is connected to the first worm. The first worm gear and the first worm engage in transmission. The drive base is fixed to the connecting platform.

[0008] Preferably, it further includes a transverse rotation mechanism, which includes a rotating plate, a motor, a driving wheel, a driven wheel, a belt, a transmission shaft, a worm gear, a worm, a rotating shaft, a bushing, and a turntable. The other end of the connecting platform extends through the bearing seat, and the portion of the connecting platform extending through the bearing seat is connected to the rotating plate. The motor is fixed on the rotating plate, and the output end of the motor is connected to the driving wheel. The driving wheel and the driven wheel are driven by the belt. An arc-shaped groove is provided on the bearing seat, and the transmission shaft passes through the arc-shaped groove. The end of the transmission shaft is connected to the worm. The bushing is located at the center of the connecting platform, and the rotating shaft is rotatably connected to the bushing. The bottom of the rotating shaft is connected to the worm gear, and the worm gear meshes with the worm. The top of the rotating shaft is connected to the turntable, and the drive seat is fixed on the turntable.

[0009] Preferably, the clamping assembly includes a fixed plate, a connecting frame, a telescopic column, a spring, and a pressure plate. The connecting frame is mounted on a bracket, the fixed plate is mounted on the connecting frame, the pressure plate and the fixed plate are connected by the telescopic column, and the spring is sleeved on the outside of the telescopic column.

[0010] Preferably, a bidirectional cylinder is fixedly connected to the pressure plate, and the two output ends of the bidirectional cylinder are provided with grippers. The bidirectional cylinder is disposed between the pressure plate and the fixed plate.

[0011] Preferably, the support is provided with a vertical moving component, which drives the clamping assembly to move in the vertical direction.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. When the worm gear driven by the geared motor rotates, the meshing transmission between the worm gear and the worm wheel drives the connecting table to rotate back and forth. The connecting table can drive the car mold to rotate at a suitable angle in the vertical plane, which can make the mold surface and the cutting direction of the tool maintain a more ideal angular relationship. This allows the tool to cut in a direction that is almost perpendicular to the machined surface, which helps to reduce the unevenness of the cutting force of the tool and improve the machining accuracy.

[0014] 2. Motor 1 drives the driven wheel and drive shaft to rotate through the drive wheel and belt, thereby causing the worm gear 2 at the end of the drive shaft to rotate. When the worm gear 2 rotates, the rotating shaft and the top turntable will rotate accordingly, realizing the lateral rotation of the drive seat. By adding a lateral rotating component to the existing vertical rotating component, the three-dimensional angle of the car mold can be precisely adjusted. Some complex three-dimensional curved surfaces on the car mold, such as the corner part of the front bumper mold, have both vertical curvature and lateral bending. Through the synergistic effect of the two rotating components, the mold can achieve the best cutting angle with the tool at each curved surface position during the processing, further reducing the roughness of the machined surface.

[0015] 3. The spring sleeve is installed on the outside of the telescopic column, providing an elastic buffer for the pressure plate. During the mold placement process, the spring can absorb the impact force when the mold is placed, avoiding damage to the mold and fixture due to collision. The buffering effect is much stronger than the protective pad. The gripper on the bidirectional cylinder can further adjust the clamping range. Through the extension and retraction of the bidirectional cylinder, the gripper can accurately position and clamp the mold from both sides according to the specific shape and size of the mold.

The clamping assemblies 3 are respectively mounted on the bracket 2, and the bracket 2 is mounted on the drive base 1. The drive base 1 drives the brackets 2 to move closer or further apart. The drive base 1 is fixed to the vertical rotation mechanism 4. The vertical rotation mechanism 4 includes a reduction motor 401, a first worm gear 402, a first worm 403, a first bearing seat 404, a second bearing seat 405, and a connecting platform 406. The two ends of the connecting platform 406 are rotatably connected between the first bearing seat 404 and the second bearing seat 405. One end of the connecting platform 406 passes through the first bearing seat 404, and the end of the connecting platform 406 is connected to the first worm gear 402. The geared motor 401 is fixed on the outside of the bearing housing 404. The output end of the geared motor 401 is connected to the worm gear 403. The worm wheel 402 and the worm gear 403 mesh and drive each other. The drive seat 1 is fixed on the connecting platform 406. With this design, the geared motor 401 drives the worm gear 403 to rotate. The meshing transmission of the worm gear and worm wheel drives the connecting platform 406 to rotate back and forth. The connecting platform 406 can drive the car mold to rotate at a suitable angle in the vertical plane, which can make the mold surface maintain a more ideal angular relationship with the cutting direction of the tool. This allows the tool to cut in a direction that is almost perpendicular to the machined surface, which helps to reduce the unevenness of the cutting force of the tool and improve the machining accuracy.

[0026] Example 2

[0027] It also includes a transverse rotation mechanism 5, which comprises a rotating plate 501, a first motor 502, a driving wheel 503, a driven wheel 504, a belt 505, a transmission shaft 506, a second worm gear 507, a second worm 508, a rotating shaft 509, a bushing, and a turntable 510. The other end of the connecting platform 406 extends from the second bearing seat 405, and the portion of the connecting platform 406 extending through it is connected to the rotating plate 501. The first motor 502 is fixed on the rotating plate 501. The output end of the first machine 502 is connected to the driving wheel 503. The driving wheel 503 and the driven wheel 504 are driven by the belt 505. The bearing housing 405 has an arc-shaped groove 511. The drive shaft 506 passes through the arc-shaped groove 511. The end of the drive shaft 506 is connected to the second worm gear 508. The bushing is set at the center of the connecting platform 406. The rotating shaft 509 is rotatably connected to the bushing. The bottom of the rotating shaft 509 is connected to the second worm wheel 507. The second worm wheel 507 meshes with the second worm gear 508. The drive shaft 509 is connected to the top of the turntable 510, and the drive seat 1 is fixed on the turntable 510. With this design, the motor 502 drives the driven wheel 504 and the drive shaft 506 to rotate through the drive wheel 503 and the belt 505. This causes the worm gear 508 at the end of the drive shaft 506 to drive the worm wheel 507 to rotate. When the worm wheel 507 rotates, the shaft 509 and the turntable 510 at the top will rotate accordingly, realizing the lateral rotation of the drive seat 1. By adding a lateral rotation component on the basis of the existing vertical rotation component, the three-dimensional angle of the car mold can be precisely adjusted. Some complex three-dimensional curved surfaces on the car mold, such as the corner part of the front bumper mold, have both vertical curvature and lateral bending. Through the synergistic effect of the two rotation components, the mold can achieve the best cutting angle with the tool at each curved surface position during the processing, further reducing the roughness of the machined surface.

The two-way cylinder 306 is located between the pressure plate 305 and the fixed plate. Between 302, spring 304 is sleeved on the outside of telescopic column 303, providing an elastic buffer for pressure plate 305. During mold placement, spring 304 can absorb the impact force during mold placement, avoiding damage to the mold and fixture due to collision. The buffering effect is much stronger than that of protective pad. The gripper 307 on the bidirectional cylinder 306 can further adjust the clamping range.
