Description

Technical Field

[0001] This utility model relates to the field of chuck technology, and in particular to a chuck with angle adjustment function. Background Technology

[0002] A chuck is a mechanical device used on machine tools to clamp workpieces. It is a machine tool accessory that uses the radial movement of movable jaws evenly distributed on the chuck body to clamp and position the workpiece. A chuck generally consists of three parts: the chuck body, the movable jaws, and the jaw drive mechanism. Chucks are commonly used on lathes, external cylindrical grinding machines, and internal cylindrical grinding machines, and can also be used with various indexing devices on milling machines and drilling machines.

[0003] Existing chucks typically use a small bevel gear to drive a large bevel gear to rotate when clamping objects to be processed. This drives multiple jaws to move closer or further apart synchronously via a drive helical groove, enabling clamping operations on different objects. However, this method has certain limitations. The objects clamped in this way must be cylindrical. When encountering objects with irregular surfaces, it is impossible to apply force in every direction, which poses a danger during processing. To better clamp irregular objects, a chuck with angle adjustment function is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a chuck with angle adjustment function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chuck with angle adjustment function includes a chuck body, a plurality of sleeves fixedly connected to the inner wall of the chuck body, and a threaded rod rotatably connected to the inner wall of each of the sleeves. The surface of the threaded rod is provided with a square hole. A plurality of jaws are slidably connected to the inner wall of the chuck body. The lower surface of each jaw is provided with a threaded groove, which fits against the surface of the threaded rod. An angle adjustment and positioning mechanism is provided on the surface of each jaw.

[0007] Preferably, the angle adjustment and positioning mechanism includes a pair of fixed plates fixedly connected to the surface of the chuck, a worm gear rotatably connected to the inner wall of the pair of fixed plates, and a cross handwheel fixedly connected to the surface of the worm gear.

[0008] Preferably, a top block is fixedly connected to the surface of the chuck, a screw is rotatably connected to the inner wall of the chuck, one end of the screw is rotatably connected to the surface of the top block, and a worm gear is fixedly connected to one end of the screw, the worm gear meshing with the worm.

[0009] Preferably, the screw has a threaded connection to a slider and a positioning plate, the slider is fixedly connected to the surface of the positioning plate, the lower surface of the slider is slidably connected to the surface of the chuck, and an L-shaped rod is rotatably connected to the surface of the slider.

[0010] Preferably, a semi-circular clamp is fixedly connected to the surface of the L-shaped rod, and a first V-shaped plate and a second V-shaped plate are rotatably connected to the inner wall of the semi-circular clamp.

[0011] Preferably, the upper surface of the L-shaped rod is provided with multiple slots, and the inner wall of the positioning plate is slidably connected with a positioning pin, which is adapted to the slot.

[0012] Preferably, a spring is fitted onto the surface of the positioning pin, the top end of the spring is fixedly connected to the surface of the positioning pin, and the bottom end of the spring is fixedly connected to the upper surface of the positioning plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] The worm gear drives the screw to rotate, causing the slider and positioning plate to slide on the surface of the chuck for position adjustment. When clamping an irregular object surface, the L-shaped rod rotates, causing the surfaces of the first V-shaped plate and the second V-shaped plate to apply force and squeeze the irregular object surface. The positioning pin keeps the L-shaped rod in a stable position, and the surface of the top block contacts and squeezes the object surface. Multiple angle positions clamp the irregular object surface to prevent the risk of detachment during processing. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A chuck with angle adjustment function includes a chuck body 1. A plurality of sleeves 19 are fixedly connected to the inner wall of the chuck body 1. A threaded rod 2 is rotatably connected to the inner wall of each of the sleeves 19. A square hole 20 is opened on the surface of the threaded rod 2. A plurality of jaws 3 are slidably connected to the inner wall of the chuck body 1. A threaded groove 18 is opened on the lower surface of the jaw 3. The threaded groove 18 fits against the surface of the threaded rod 2. An angle adjustment and positioning mechanism is provided on the surface of the jaw 3.

[0023] By setting the sleeve 19, the rotation of the threaded rod 2 is kept stable. By setting the square hole 20, the tool applies force to the square hole 20 to drive the threaded rod 2 to rotate. By setting the threaded rod 2 to cooperate with the threaded groove 18, the single jaw 3 is driven to adjust its position in the chuck body 1. By setting the angle adjustment positioning mechanism, auxiliary clamping is performed to ensure that irregular objects are kept stable during processing.

[0024] In this utility model, the angle adjustment and positioning mechanism includes a pair of fixed plates 4 fixedly connected to the surface of the claw 3, a worm gear 5 rotatably connected to the inner wall of the pair of fixed plates 4, and a cross handwheel 7 fixedly connected to the surface of the worm gear 5.

[0025] By setting the fixing plate 4, the rotation of the worm gear 5 is kept stable. By setting the cross handwheel 7, the rotation of the worm gear 5 can be manually driven.

[0026] In this utility model, a top block 17 is fixedly connected to the surface of the claw 3, and a screw 8 is rotatably connected to the inner wall of the claw 3. One end of the screw 8 is rotatably connected to the surface of the top block 17, and a worm gear 6 is fixedly connected to one end of the screw 8. The worm gear 6 meshes with the worm 5.

[0027] By setting the top block 17, the object is clamped on one side. By setting the worm gear 6, the screw 8 is driven to rotate. The screw 8 adjusts the position of the slider 9 and the positioning plate 10.

[0028] In this utility model, the surface of the screw 8 is threadedly connected to a slider 9 and a positioning plate 10. The slider 9 is fixedly connected to the surface of the positioning plate 10. The lower surface of the slider 9 is slidably connected to the surface of the claw 3. An L-shaped rod 13 is rotatably connected to the surface of the slider 9.

[0029] By setting slider 9, the L-shaped rod 13 is supported to rotate, and by setting L-shaped rod 13, the position of semicircular clamp 14 is adjusted.

[0030] In this utility model, a semi-circular clamp 14 is fixedly connected to the surface of the L-shaped rod 13, and a first V-shaped plate 15 and a second V-shaped plate 16 are rotatably connected to the inner wall of the semi-circular clamp 14.

[0031] By setting the first V-shaped plate 15 and the second V-shaped plate 16, when the first V-shaped plate 15 and the second V-shaped plate 16 come into contact with the surface of the object and are subjected to force, the first V-shaped plate 15 and the second V-shaped plate 16 will automatically adapt to the rotation within the semi-circular clamp 14. By having multiple surfaces in contact with the surface of the irregular object, the stability of the irregular object is maintained.

[0032] In this utility model, the upper surface of the L-shaped rod 13 is provided with a plurality of slots 21, and the inner wall of the positioning plate 10 is slidably connected with a positioning pin 12, which is adapted to the slots 21.

[0033] By setting the slot 21 to cooperate with the positioning pin 12, the positioning of the L-shaped rod 13 is kept stable.

[0034] In this utility model, a spring 11 is sleeved on the surface of the positioning pin 12, the top end of the spring 11 is fixedly connected to the surface of the positioning pin 12, and the bottom end of the spring 11 is fixedly connected to the upper surface of the positioning plate 10.

[0035] By setting spring 11, the positioning pin 12 is reset and kept stable.

[0036] Working principle: When clamping irregular objects, the necessary tools can be inserted into the square hole 20, and the single threaded rod 2 can be rotated for adjustment. The rotation of the threaded rod 2 changes the sliding position of the jaw 3 through the threaded groove 18, so that the surface of the top block 17 contacts and presses against the surface of the object. Then, the cross handwheel 7 can be rotated. The rotation of the cross handwheel 7 drives the worm wheel 6 to rotate through the worm 5. The worm wheel 6 drives the screw 8 to rotate, so that the slider 9 and the positioning plate 10 slide on the surface of the jaw 3 for adjustment. When clamping the surface of an irregular object, the L-shaped rod 13 can be rotated, so that the surfaces of the first V-shaped plate 15 and the second V-shaped plate 16 apply force to the surface of the irregular object. By inserting the positioning pin 12 into the corresponding slot 21, the positioning of the L-shaped rod 13 is kept stable. The irregular object surface is clamped at multiple angles to maintain stability and prevent the risk of detachment during processing.
