Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, specifically to an ultra-thin chuck with micro-adjustment components. Background Technology

[0002] In the field of machining, chucks (such as spring collets and hydraulic collets) are key clamping components on machine tools (such as lathes, milling machines, and grinding machines) used to hold workpieces or cutting tools. In practical applications, traditional chucks often cannot meet the diverse workpiece clamping needs, resulting in limited clamping angle adjustment functions. They mostly adopt fixed structures or simple mechanical adjustment methods, which cannot flexibly fine-tune the angle of the jaws for workpieces with different curved surfaces or irregular shapes to adapt to the clamping of workpieces with different shapes. For example, in the machining of small and complex workpieces such as electronic components and precision molds, traditional chucks are mostly flat, which makes it difficult to fit the contour of round workpieces when clamping and fixing them. This can easily lead to problems such as workpiece shaking and displacement during machining, which not only reduces machining accuracy but may also cause workpiece damage, resulting in material waste and production delays.

[0003] Therefore, this utility model provides an ultra-thin chuck with micro-adjustment components. Utility Model Content

[0004] To address the problem that existing chucks have limited angle adjustment capabilities and cannot flexibly fine-tune the angle of the jaws for workpieces with different curved surfaces or irregular shapes, the purpose of this invention is to provide an ultra-thin chuck with a micro-adjustment component.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultra-thin chuck with a micro-adjustment component, comprising a chuck device, wherein a clamping mechanism is provided on one side of the chuck device for clamping different workpieces, and the chuck device includes:

[0006] The fine-tuning component includes two driven jaws symmetrically distributed on one side of the chuck device. A screw is rotatably mounted on the middle of one side of each of the two driven jaws. A drive component is provided on one side of each of the two screws. A moving block is threadedly mounted on the middle of the middle of each of the two screws. A drive rod is rotatably mounted on the middle of one side of each of the two moving blocks. A fixed clamping plate is fixedly mounted on one side of each of the two driven jaws. A rotating clamping plate is rotatably mounted on one side of each of the two fixed clamping plates. The other ends of the two drive rods are movably mounted on the middle of one side of the rotating clamping plate.

[0007] The mounting component, located on one side of the chuck device, is used to mount the driven gripper.

[0008] Preferably, the mounting assembly includes an active gripper fixedly mounted on the drive end of the chuck device, and the active gripper has two grippers that cooperate with each other. One end of each of the two active grippers has four symmetrically distributed threaded grooves. One side of each of the two driven grippers has four symmetrically distributed mounting blocks fixedly mounted. The mounting blocks are slidably engaged on one side of the active gripper, and bolts are slidably passed through the middle of the mounting blocks. One end of each bolt is threaded into the middle of the threaded groove.

[0009] Preferably, the drive assembly includes a servo motor fixedly mounted on one end of the driven gripper, and one end of each of the two screws fixedly mounted on the drive end of the servo motor.

[0010] Preferably, a cavity is provided in the middle of one side of each of the two driven grippers, and the two moving blocks are slidably locked in the middle of the cavity.

[0011] Preferably, a first conveyor belt is rotatably mounted on the middle of each of the two rotating clamping plates, and a second conveyor belt is rotatably mounted on the middle of each of the two fixed clamping plates.

[0012] Preferably, one end of each of the two active grippers is provided with a positioning groove, and one end of each of the two driven grippers is fixedly installed with a positioning block, and the two positioning blocks are slidably engaged inside the positioning groove.

[0013] Beneficial effects

[0014] This invention provides an ultra-thin chuck with micro-adjustment components. Compared with the prior art, it has the following advantages:

[0015] 1. This application uses a servo motor to drive the screw to rotate, and utilizes the thread transmission principle to make the moving block move linearly in the cavity, which in turn drives the drive rod to push the rotating clamping plate to rotate around the fixed clamping plate. By finely adjusting the angle between the rotating clamping plate and the fixed clamping plate, the chuck can respond quickly and complete the angle adjustment when facing workpieces with different curved surfaces or irregular shapes. By changing the clamping angle to fit the contour of the workpiece, the clamping adaptability and stability of workpieces with different shapes are greatly improved.

[0016] 2. This application aligns the threaded groove on the active gripper with the mounting block of the driven gripper, and connects them with bolts, allowing the driven gripper to be quickly installed on one end of the active gripper. This enables the driven gripper to be quickly installed and removed, facilitating maintenance, replacement, and adjustment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an ultra-thin chuck with micro-adjustment components, including a chuck device 1, a clamping mechanism 2 on one side of the chuck device 1 for clamping different workpieces, and the chuck device 1 includes:

[0024] The fine-tuning component 21 includes a driven gripper 211 disposed on one side of the chuck device 1. Two driven grippers 211 are symmetrically distributed. A screw 212 is rotatably mounted on the middle of one side of each of the two driven grippers 211. A drive component is disposed on one side of each of the two screws 212. A moving block 213 is threadedly mounted on the middle of one side of each of the two moving blocks 213. A drive rod 214 is rotatably mounted on the middle of one side of each of the two driven grippers 211. A fixed clamping plate 218 is fixedly mounted on one side of each of the two fixed clamping plates 218. A rotating clamping plate 217 is rotatably mounted on one side of each of the two fixed clamping plates 218. The other ends of the two drive rods 214 are movably mounted on the middle of one side of each of the rotating clamping plates 217.

[0025] Mounting component 22 is disposed on one side of the chuck device 1 and is used to mount the driven gripper 211.

[0026] The mounting assembly 22 includes an active gripper 221 fixedly mounted on the drive end of the chuck device 1. The active gripper 221 has two grippers that cooperate with each other. One end of each active gripper 221 has four symmetrically distributed threaded grooves 224. One side of each of the two driven grippers 211 has four symmetrically distributed mounting blocks 222 fixedly mounted. The mounting blocks 222 are slidably engaged on one side of the active gripper 221. The middle of each mounting block 222 is slidably penetrated by a bolt 223. One end of each bolt 223 is threaded into the middle of the threaded groove 224. The mounting surfaces of the active gripper 221 and the driven gripper 211 are precision ground to ensure that the two are tightly fitted together.

[0027] The drive assembly includes a servo motor 216 fixedly mounted on one end of the driven gripper 211, and one end of each of the two screws 212 fixedly mounted on the drive end of the servo motor 216. The servo motor 216 is a hollow cup micro servo motor of model ECX13, with an outer diameter of only 13mm and a length of 22.9mm, which is very suitable for the narrow space of ultra-thin grippers.

[0028] Each of the two driven grippers 211 has a cavity 215 in the middle of one side, and the two moving blocks 213 are slidably locked in the middle of the cavity 215. By opening the cavity 215, the moving blocks 213 can be limited, making the movement of the moving blocks 213 more stable.

[0029] A first conveyor belt 2171 is rotatably mounted in the middle of each of the two rotating clamping plates 217, and a second conveyor belt 2181 is rotatably mounted in the middle of each of the two fixed clamping plates 218. Both the first conveyor belt 2171 and the second conveyor belt 2181 are driven by conventional servo motors, which will not be elaborated on here. By driving the first conveyor belt 2171 and the second conveyor belt 2181 to rotate, the position of the workpiece can be adjusted while clamping it.

[0030] Each of the two active grippers 221 has a positioning groove 226 at one end, and each of the two driven grippers 211 has a positioning block 225 fixedly installed at one end. The two positioning blocks 225 are slidably locked inside the positioning groove 226. With the cooperation of the positioning groove 226 and the positioning block 225, the driven gripper 211 and the active gripper 221 can be installed conveniently, and the structure can be made more stable after the two are connected.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, when it is necessary to clamp workpieces with different curved surfaces, the screw 212 can be rotated by the servo motor 216, which in turn causes the moving block 213 to move to one side, causing one end of the drive rod 214 to move. Under the drive of the drive rod 214, the rotating clamping plate 217 can rotate around one end of the fixed clamping plate 218, thereby adjusting the angle between the rotating clamping plate 217 and the fixed clamping plate 218, so as to clamp workpieces with different curvatures and make the clamping of the workpiece more stable.

[0033] During installation, by aligning the opening of the mounting block 222 with the threaded groove 224, the bolt 223 is threaded into the threaded groove 224 after passing through the through hole. This allows the driven jaw 211 and the active jaw 221 to be connected to each other. Under the drive of the chuck device 1, the two active jaws 221 move relative to each other, which in turn drives the driven jaw 211 to move relative to each other, thereby clamping the workpiece.
