Technical Field

[0001] This utility model belongs to the field of machine tool chuck technology, specifically an adaptive multi-directional adjustable machine tool chuck device. Background Technology

[0002] Machine tool chucks are mechanical devices used to clamp and position workpieces in machine tool accessories. They are widely used in various machine tools, such as lathes, milling machines, and grinding machines. Their main function is to clamp and position the workpiece by the radial movement of the movable jaws evenly distributed on the chuck body.

[0003] Traditional chucks are mostly designed specifically for the workpiece, or they use metal plates as chucks to clamp a certain type of workpiece. These chucks can only clamp workpieces of a specific shape and are not very versatile. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an adaptive multi-directional adjustable machine tool chuck device, which solves the problem that traditional chucks can only clamp workpieces of specific shapes and have low applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adaptive multi-directional adjustable machine tool chuck device, including a chuck base, a fixed plate connected to the chuck base, multiple auxiliary gears rotatably connected inside the chuck base, a motor installed inside the chuck base, a main gear installed on the output shaft of the motor, multiple guide grooves opened on the fixed plate, a connecting plate slidably connected inside the guide grooves, a cross plate connected below the connecting plate, and spring plates connected to both sides of the connecting plate;

[0006] A connecting spring is connected inside the connecting plate. One end of the connecting spring is connected to a movable plate. A sliding groove is provided on the movable plate. A first half-tooth block is connected to one side of the movable plate. The first half-tooth block is rotatably connected to a hinge plate by a pin. One end of the hinge plate is rotatably connected to a second half-tooth block by a pin. An abutment block is connected to the second half-tooth block.

[0007] As a further embodiment of this utility model: the spring plates on both sides of the connecting plate are connected by fastening bolts, the fastening bolts slide in the grooves, and the fastening bolts are threaded with fastening nuts.

[0008] As a further embodiment of this utility model: there are three auxiliary gears arranged evenly in a centrally symmetrical manner, the auxiliary gears mesh with the main gears, and a fixed rod is connected to the auxiliary gears.

[0009] As a further embodiment of this utility model: a strip groove is provided on the cross plate, the fixing rod slides in the strip groove, and the cross plate is disposed between the fixing plate and the auxiliary gear.

[0010] As a further embodiment of this utility model: an anti-slip rubber layer is provided on the side of the abutting block away from the second half-tooth block, and the first half-tooth block and the second half-tooth block mesh with each other.

[0011] As a further embodiment of this utility model: connecting grooves are provided on both sides of the guide groove, and connecting strips are connected to both sides of the connecting plate, and the connecting strips are slidably connected to the connecting grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This adaptive multi-directional adjustable machine tool chuck device, by setting up a connecting spring, a movable plate, a first half-tooth block, a second half-tooth block, and an abutment block, allows the workpiece to push the movable plate to move when the abutment block contacts the workpiece. This causes the movable plate to move into the connecting plate and compress the connecting spring. At this time, the fastening bolt slides in the groove. By tightening the fastening nut, the fastening bolt and the fastening nut together squeeze the spring plate, causing the spring plates on both sides to clamp and fix the movable plate. This allows multiple movable plates to clamp and fix the workpiece together. At the same time, the abutment block is also pushed, causing the first half-tooth block and the second half-tooth block to mesh and rotate, thereby adjusting the orientation of the abutment block. This allows the abutment block to contact the surface of workpieces with different shapes, improving its applicability.

[0014] 2. This adaptive multi-directional adjustable machine tool chuck device, by setting up a motor, main gear, auxiliary gear, fixed rod, strip groove, connecting bar and connecting groove, allows the operator to start the motor to rotate the main gear. The meshing relationship between the main gear and auxiliary gear synchronously drives multiple auxiliary gears to rotate, while the fixed rod rotates with the auxiliary gears, thus sliding in the strip groove and pushing the cross plate. The cross plate then drives the connecting plate, causing the connecting bar to slide in the connecting groove, thereby adjusting the position of multiple connecting plates and causing the movable plate to clamp and fix the workpiece, preventing the workpiece from sliding or deviating during processing.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: an adaptive multi-directional adjustable machine tool chuck device, including a chuck base 1, a fixed plate 2 connected to the chuck base 1, and multiple auxiliary gears 3 rotatably connected inside the chuck base 1. The three auxiliary gears 3 are evenly arranged in a centrally symmetrical manner. The auxiliary gears 3 mesh with the main gear 5. A fixed rod 19 is connected to the auxiliary gear 3. Through the meshing of the main gear 5 and the auxiliary gears 3, the motor 4 can synchronously drive the multiple auxiliary gears 3 to rotate, causing the fixed rod 19 to push the cross plate 8 to move multiple movable plates 11 to clamp and fix the workpiece. The movable plates 11 can clamp workpieces of different sizes, improving applicability.

[0023] A motor 4 is installed inside the chuck base 1. A main gear 5 is installed on the output shaft of the motor 4. Multiple guide grooves 6 are provided on the fixed plate 2. Connecting grooves 21 are provided on the side walls of the guide grooves 6. Connecting strips 22 are connected to both sides of the connecting plate 7. The connecting strips 22 are slidably connected to the connecting grooves 21. By sliding the connecting strips 22 in the connecting grooves 21, the fixed plate 2 can support the connecting plate 7 and the cross plate 8, and both the connecting plate 7 and the cross plate 8 can slide smoothly along the direction of the guide grooves 6.

[0024] A connecting plate 7 is slidably connected in the guide groove 6. A fastening bolt 17 is connected through the spring plates 9 on both sides of the connecting plate 7. The fastening bolt 17 slides in the slide groove 12. A fastening nut 18 is threaded on the fastening bolt 17. When the operator tightens the fastening nut 18, the fastening bolt 17 and the fastening nut 18 will simultaneously squeeze the spring plate 9, thereby deforming the spring plate 9 and causing the spring plate 9 to clamp and fix the movable plate 11, preventing the movable plate 11 from sliding accidentally.

[0025] A cross plate 8 is connected below the connecting plate 7. A strip groove 20 is provided on the cross plate 8. The fixing rod 19 slides in the strip groove 20. The cross plate 8 is located between the fixing plate 2 and the auxiliary gear 3. By sliding the fixing rod 19 in the strip groove 20, the fixing rod 19 can push the cross plate 8 when the auxiliary gear 3 rotates, thereby driving the connecting plate 7 and the movable plate 11 to move, causing the abutment block 16 on the movable plate 11 to contact the workpiece, thereby clamping and fixing the workpiece.

[0026] Spring plates 9 are connected to both sides of the connecting plate 7, and a connecting spring 10 is connected inside the connecting plate 7. One end of the connecting spring 10 is connected to a movable plate 11, and a sliding groove 12 is provided on the movable plate 11. A first half-tooth block 13 is connected to one side of the movable plate 11. The first half-tooth block 13 is rotatably connected to a hinge plate 14 via a pin. One end of the hinge plate 14 is rotatably connected to a second half-tooth block 15 via a pin. An abutment block 16 is connected to the second half-tooth block 15. An anti-slip rubber layer is provided on the side of the abutment block 16 away from the second half-tooth block 15. The first half-tooth block 13 and the second half-tooth block 15 mesh with each other. The movable plate 11 moves to the inside of the connecting plate 7 to compress the connecting spring 10, so that the abutment block 16 on the movable plate 11 can adapt to workpieces of different shapes and sizes. The meshing and rotation of the first half-tooth block 13 and the second half-tooth block 15 allows for multi-directional adjustment of the angle of the abutment block 16, so that the abutment block 16 contacts the surface of the workpiece, thereby improving applicability.

[0027] The working principle of this utility model is as follows:

[0028] The operator starts the motor 4 to rotate the main gear 5, which in turn drives multiple auxiliary gears 3 to rotate synchronously. The fixing rod 19 rotates along with the auxiliary gears 3, allowing it to slide within the strip groove 20 and push the cross plate 8. This causes the cross plate 8 to drive the connecting plate 7, making the connecting strip 22 slide within the connecting groove 21. This brings the multiple connecting plates 7 closer to the workpiece. When the abutting block 16 contacts the workpiece, the workpiece pushes the movable plate 11 to move, causing it to move into the connecting plate 7 and compress the connecting spring 10. At this time, the fastening bolt 17 slides within the slide groove 12. By tightening the fastening nut 18, the fastening bolt 17 and the fastening nut 18 together compress the spring plate 9, causing it to deform and clamp the movable plate 11. Simultaneously, the abutting block 16 is pushed, causing the first half-tooth block 13 and the second half-tooth block 15 to mesh and rotate, thus adjusting the orientation of the abutting block 16 so that it can contact the surfaces of workpieces of different shapes.
