Description

Technical Field

[0001] This utility model relates to the field of chuck technology, and in particular to an adjustable machine tool chuck. Background Technology

[0002] Machine tool chucks are tools used to fix and clamp workpieces during machining. They are usually mounted on the spindle or worktable of a machine tool and achieve firm clamping of the workpiece through mechanical, hydraulic or pneumatic means. The design and construction of machine tool chucks vary depending on the application. Their main function is to ensure that the workpiece remains stable during machining, thereby improving machining accuracy and efficiency.

[0003] Existing machine tool chucks mainly use three-jaw chucks. When in use, the chuck jaws move inward by manually rotating the screw to clamp the workpiece. When rotating the screw, the chuck jaws will move evenly towards the center to clamp the workpiece. The clamping jaws also need to be locked to prevent the chuck jaws from moving during the machining process, thus achieving the effect of clamping the workpiece.

[0004] When using existing machine tool chucks, it is necessary to process workpieces of different shapes. For some special workpieces, tilting clamping is required. However, existing machine tool chucks are fixedly installed on the machine tool and cannot be tilted. This makes it impossible to adjust the chucks when processing workpieces that require tilting, which is quite inconvenient to use. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides an adjustable machine tool chuck. It has the following advantages:

[0019] 1. The ratchet is unlocked or locked by raising or lowering the threaded pin. Rotating the drive shaft drives the threaded cylinder to rotate through the cooperation of the drive bevel gear and the driven bevel gear, causing the threaded column to rise inside the threaded cylinder. This causes one side of the tilting plate to rise and tilt, thus achieving the tilt setting of the clamped workpiece for convenient processing.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3This is the first embodiment of the present invention. This embodiment provides an adjustable machine tool chuck, including a main body 1. A chuck component 2 is provided inside the main body 1. A fixed cylinder 3 is provided below the main body 1. An inclined component 4 is provided inside the fixed cylinder 3. The inclined component 4 includes an inclined plate 401 disposed inside the fixed cylinder 3. Three hinge seats 411 are movably connected to the lower surface of the inclined plate 401 through bearings. Threaded columns 402 are hinged to the outer surface of the hinge seats 411. Three threaded cylinders 403 are movably connected inside the fixed cylinder 3. The inner surface of the threaded cylinders 403 is engaged with the outer surface of the threaded columns 402.

[0030] Specifically, a driven bevel gear 404 is fixedly connected to the outer surface of the threaded cylinder 403, a fixed block 405 is fixedly connected to the outer surface of the fixed cylinder 3, a drive shaft 406 is inserted inside the fixed block 405, a drive bevel gear 407 is fixedly connected to the end of the drive shaft 406 near the driven bevel gear 404, the drive bevel gear 407 meshes with the driven bevel gear 404, a ratchet 408 is fixedly connected to the outer surface of the drive shaft 406, the ratchet 408 is located inside the fixed block 405, a cover plate 409 is fixedly connected to the side of the fixed block 405 away from the drive bevel gear 407, a threaded pin 410 meshes with the outer surface of the fixed block 405, the end of the threaded pin 410 near the drive shaft 406 abuts against the outer surface of the ratchet 408, and a soft extrusion block is fixedly connected to the end of the threaded pin 410 near the drive shaft 406.

[0031] Furthermore, when tilting is required, adjustment is made according to the direction of tilt. The threaded pin 410 is rotated and raised using a wrench or other tools to unlock the ratchet 408. Then, the drive shaft 406 is rotated and adjusted. The drive shaft 406 drives the threaded cylinder 403 to rotate through the engagement of the drive bevel gear 407 and the driven bevel gear 404, causing the threaded column 402 to rise inside the threaded cylinder 403. This causes one side of the tilting plate 401 to rise and achieve tilting. After adjusting the three threaded cylinders 403 and the threaded column 402 through the same steps, the tilting of the tilting plate 401 is finally completed.

[0032] Example 2

[0033] Reference Figure 1 and Figure 4This is the second embodiment of the present invention. Based on the previous embodiment, an installation component 5 is provided between the upper surface of the tilting disk 401 and the main body 1. The installation component 5 includes a limiting chuck 506 fixedly connected to the upper surface of the tilting disk 401. Two insert plates 501 are fixedly connected to the lower surface of the main body 1. An insertion block 507 is fixedly connected to the lower surface of the main body 1. The insertion block 507 and the insert plates 501 are both inserted into the limiting chuck 506. A bidirectional lead screw 505 is movably connected inside the insertion block 507. The outer surfaces of both ends of the bidirectional lead screw 505 pass through the insertion block 507 and are engaged with locking blocks 503. Two rotating locking blocks 502 are movably connected to both ends of the insertion block 507.

[0034] Specifically, the upper surface of the limiting chuck 506 is provided with a rectangular through groove that cooperates with the insertion block 507, and the outer surface of the limiting chuck 506 is provided with a slot that cooperates with the insertion plate 501. The rectangular through groove and the slot are connected by a rectangular groove that cooperates with the rotating chuck 502. The locking block 503 is fixedly connected to the insertion rod 504 on the side near the insertion block 507. Both ends of the insertion block 507 are provided with insertion holes that cooperate with the insertion rod 504.

[0035] Furthermore, rotating the bidirectional lead screw 505 causes the locking block 503 to extend, thereby unlocking the rotating block 502. Then, the rotating block 502 is moved to a direction parallel to the insertion block 507, allowing the insertion block 507 to slide on the limiting chuck 506, thereby sliding the insertion block 507 and the insertion plate 501 out of the limiting chuck 506.

[0036] Working principle: When using the machine tool gripper, the fixed cylinder 3 is fixedly installed in the designated position. Then, tilting is selected as needed. When tilting is required, it is adjusted according to the direction of tilt. The threaded pin 410 is rotated and raised using a wrench or other tools, thereby unlocking the ratchet 408. Then, the drive shaft 406 is rotated and adjusted. The drive shaft 406 drives the threaded cylinder 403 to rotate through the engagement of the drive bevel gear 407 and the driven bevel gear 404, causing the threaded column 402 to rise inside the threaded cylinder 403. This achieves the tilting of one side of the tilting plate 401. After adjusting the three threaded cylinders 403 and the threaded column 402 through the same steps, the tilting plate 401 is finally tilted, allowing the main body 1 and the gripper component 2 located above the tilting plate 401 to tilt. The workpiece can be clamped and tilted. When the main body 1 and the claw component 2 need to be replaced for different workpieces, the bidirectional screw 505 is rotated to drive the locking block 503 to extend, thereby unlocking the rotating block 502. Then, the rotating block 502 is moved to a direction parallel to the insertion block 507, so that the insertion block 507 can slide on the limiting chuck 506, thereby sliding the insertion block 507 and the insertion plate 501 out of the limiting chuck 506. The replacement main body 1 and claw component 2 are inserted into the limiting chuck 506 in the same steps. Then, the rotating block 502 is moved into the rectangular groove. Then, the bidirectional screw 505 is rotated to drive the locking block 503 to press and lock the rotating block 502, thereby completing the replacement of the main body 1 and the claw component 2, and finally completing the adjustment of the claw.
