[0026] Example 1

[0027] like Figure 1-5 As shown, this is the first embodiment of the present invention, which provides a clamping device for processing automotive interior doors, including...

[0028] The adjustment unit 100 includes a base 110, a first motor 120 fixedly connected to the inner cavity of the base 110, a screw 130 drivenly connected to the output shafts on both sides of the first motor 120, a sleeve 140 threadedly connected to the surface of the screw 130, a support 150 disposed at both ends of the base 110, and a cylinder 160 fixedly connected to the bottom of the inner cavity of the support 150.

[0029] The clamping unit 200 includes a housing 210, a second motor 220 fixedly connected to the lower end of the inner cavity of the housing 210, a drive gear 230 disposed on the lower end of one side of the housing 210, a driven gear 240 disposed above the drive gear 230, and a clamping assembly 250 disposed on one side of the driven gear 240.

[0030] like Figure 1-5 As shown, the first motor 120 drives the screws 130 on both sides of the output shaft to rotate, and the sleeve 140 moves along the screws 130. This drives the support 150 and the clamping unit 200 to move synchronously, thereby adjusting the spacing of the clamping unit 200. At the same time, the output end of the cylinder 160 drives the clamping unit 200 to adjust its height, thus adapting to different sizes of automotive interior doors. The output shaft of the second motor 220 drives the drive gear 230 to rotate. Since the drive gear 230 and the driven gear 240 mesh, the driven gear 240 will rotate accordingly, thereby driving the clamping assembly 250 to rotate synchronously. This allows for multi-angle adjustment of the clamping assembly 250 to meet different clamping requirements. The clamping assembly 250 can stably clamp the automotive interior door, ensuring the stability of subsequent processing.

[0031] Example 2

[0032] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] In this embodiment, the clamping assembly 250 includes an electric push rod 251, a connecting frame 252 fixedly connected to one side of the driven gear 240, a movable block 253 movably connected to the inner cavity of the connecting frame 252, a gripper 255 movably connected to the front and rear ends of the connecting frame 252 via a rotating shaft, a connecting strip 254 movably connected between the movable block 253 and the gripper 255 via a pin, and a rubber pad 256 fixedly connected to the side of the two grippers 255 that are close to each other.

[0034] The output end of the electric push rod 251 passes through the housing 210, the driven gear 240 and the connecting frame 252 in sequence, and extends into the inner cavity of the connecting frame 252. It is movably connected to the movable block 253 through a bearing. One end of the electric push rod 251 is fixedly connected to one side of the inner cavity of the housing 210.

[0035] The side of the rubber pad 256 away from the gripper 255 contacts the workpiece to be clamped. The driving gear 230 and the driven gear 240 mesh with each other. The output shaft of the second motor 220 extends through to the outside of the cover 210 and is connected to the driving gear 230 for transmission.

[0036] like Figure 1-3As shown, an electric push rod 251 serves as the power source for the clamping action, driving the movable block 253 to move within the connecting frame 252. A rubber pad 256 is fixedly connected to the side of the two grippers 255 that are close to each other. The side of the rubber pad 256 away from the grippers 255 contacts the workpiece to be clamped. The rubber pad 256 has good elasticity and friction, increasing the friction between the grippers 255 and the workpiece, improving clamping stability. Its elasticity also allows it to deform according to the shape of the automotive interior door surface, ensuring a tight fit and improving clamping quality. During use, the output end of the electric push rod 251 drives the movable block 253 to move within the connecting frame 252. The movement of the movable block 253 is transmitted to the grippers 255 via the connecting strip 254. The gripper 255 closes, and the rubber pad 256 contacts the interior door of the car to be clamped, thus clamping the interior door. After processing, the electric push rod 251 is activated again, causing the movable block 253 to move in the opposite direction. The movable block 253 drives the gripper 255 to open through the connecting strip 254, releasing the interior door for easy removal. The output shaft of the second motor 220 is connected to the drive gear 230, and the drive gear 230 and the driven gear 240 mesh. When the second motor 220 is started, its output shaft drives the drive gear 230 to rotate. Since the drive gear 230 and the driven gear 240 are meshed, the driven gear 240 will rotate accordingly, realizing the transmission of power and facilitating the multi-angle adjustment of the clamping assembly 250.

[0037] Example 3

[0038] Reference Figure 1 , 4 5 and 6 are the third embodiment of this utility model, which is based on the first two embodiments.

[0039] In this embodiment, one end of the sleeve 140 penetrates the inner cavity of the base 110 and extends to the outside of the base 110 and is fixedly connected to the support 150, and the output end of the cylinder 160 is fixedly connected to the bottom of the cover 210.

[0040] Mounting plates 112 are fixedly connected to both sides of the front and back of the base 110, and mounting holes are provided on the top of the mounting plates 112.

[0041] A limiting rod 141 is fixedly connected to the bottom of the sleeve 140, and a limiting groove 111 is opened at the bottom of the inner cavity of the base 110. The bottom of the limiting rod 141 extends into the inner cavity of the limiting groove 111 and is slidably connected to the inner cavity of the limiting groove 111.

[0042] like Figure 1 , 4As shown in Figure 5, the sleeve 140 is connected to the support 150, and the cylinder 160 is connected to the cover 210 of the clamping unit 200. When the screw 130 rotates and causes the sleeve 140 to move to one side, the sleeve 140 can drive the support 150 and the cylinder 160 to move synchronously. The cylinder 160 will drive the clamping unit 200 to move, thereby realizing the adjustment of the clamping distance of the clamping unit 200. At the same time, the cylinder 160 serves as a power source. When the cylinder 160 is working, its output end will drive the cover 210 to move up and down. This up-and-down movement can adjust the height of the clamping unit 200, making it easier to adapt to interior doors of different sizes. This increases the flexibility and adaptability of the clamping unit 200. By using the mounting holes on the mounting plate 112, the device can be firmly installed on the processing equipment using fasteners such as bolts, ensuring the stability and reliability of the device during operation. Through the cooperation between the limiting rod 141 and the limiting groove 111, the limiting rod 141 can slide in the limiting groove 111 when the sleeve 140 moves along the screw 130. This cooperation restricts the rotational freedom of the sleeve 140, allowing the sleeve 140 to move linearly along the axial direction of the screw 130, thereby ensuring the stability of the movement of the sleeve 140.

[0043] In use, the device is first installed on the processing equipment through the mounting holes on the mounting plates 112 on both sides of the front and back of the base 110. Then, according to the dimensions of the automotive interior door to be processed, the first motor 120 is started. The first motor 120 drives the screws 130 on both output shafts to rotate. Since the sleeve 140 is threaded onto the surface of the screw 130, and the limiting rod 141 at the bottom of the sleeve 140 slides within the limiting groove 111 at the bottom of the inner cavity of the base 110, the sleeve 140 moves along the screw 130, thereby moving the support 150. The support 150, in conjunction with the cylinder 160, moves the clamping unit 200, thus allowing adjustment of the spacing position of the clamping unit 200 until the required spacing dimension of the interior door is achieved. Simultaneously, the cylinder 160 is started, and its output end drives the clamping unit 200 to adjust its height until the required clamping height is reached, thus accommodating different automotive interior door dimensions. Afterwards, the second motor 220 is started. The output shaft of the second motor 220 drives the drive gear 230 to rotate. Since the drive gear 230 and the driven gear 240 mesh, the driven gear 240 will rotate accordingly, thereby driving the connecting frame 252 fixedly connected to one side of the driven gear 240 to rotate, thereby adjusting the angle of the clamping assembly 250 to meet the clamping requirements of multiple angles. After adjustment, by placing the car interior door to be clamped at the clamping assembly 250, the electric push rod 251 is activated. The output end of the electric push rod 251 drives the movable block 253 to move in the inner cavity of the connecting frame 252. The movable block 253 is movably connected to the gripper 255 through the connecting strip 254. When the movable block 253 moves, it will drive the gripper 255 to open and close, realizing the clamping and releasing of the car interior door. The rubber pad 256 on the side of the gripper 255 close to the part to be clamped can contact the part to be clamped, which can reduce damage to the surface of the interior door. This completes the clamping operation of the car interior door, which facilitates its subsequent processing and ensures its stability.
