[0002] In modern manufacturing, wire EDM machine tool fixtures are an important type of special processing equipment, widely used in mold manufacturing, aerospace parts processing, precision machining and many other fields. They play a key role in processing parts with various complex shapes and high precision requirements.

When processing these special-shaped workpieces, a lot of time and effort is often required to redesign and manufacture special fixtures, which not only increases production costs but also extends the production cycle and seriously affects processing efficiency.

When processing these special-shaped workpieces, a lot of time and effort is often required to redesign and manufacture special fixtures, which not only increases production costs but also extends the production cycle and seriously affects processing efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-angle adjustable clamp for a wire cutting machine tool, comprising a bed, a worktable fixedly connected to the upper surface of the bed, a processing box fixedly connected to the upper surface of the worktable, a base fixedly connected to the inner surface of the processing box, a clamping mechanism provided on the upper surface of the base, and a cutting system fixedly connected to one side surface of the worktable.

[0006] The clamping mechanism includes an inner ring, rolling balls, an outer ring, a handle, a mounting plate, a vertical plate, a rotating support, a rotary joint, a clamping base plate, a cylinder, a connecting seat, a connecting rod, a micro motor, a first conveyor belt, a bidirectional lead screw, a second conveyor belt, a driven shaft, a support plate, a connecting rod, and a clamping plate. The upper surface of the base is fixedly connected to the inner ring, the outer surface of the inner ring is fixedly connected to the rolling balls, the outer surface of the inner ring is fixedly connected to the outer ring, a handle is fixedly connected to one side surface of the outer ring, a mounting plate is fixedly connected to the upper surface of the outer ring, a vertical plate is fixedly connected to the upper surface of the mounting plate, a rotating support is fixedly connected to the upper surface of the vertical plate, and a rotary joint is fixedly connected to one side surface of the rotating support.

[0008] Preferably, the clamping base plate forms a rotating structure with a rotating joint and a rotating support, and an acute-angled locking block is provided on one side of the clamping base plate.

[0009] Preferably, the upper surface of the upright plate is provided with an acute-angled groove, and two sets of rotating supports are symmetrically arranged around the central axis of the rotating joint.

[0010] Preferably, the connecting seats are arranged in two sets symmetrically about the central axis of the cylinder, and the connecting rods are arranged in two sets symmetrically about the central axis of the cylinder.

[0011] Preferably, the bidirectional lead screw forms a rotating structure with a micro motor via a first conveyor belt, and the inner wall dimension of the first conveyor belt matches the outer wall dimension of the bidirectional lead screw.

[0012] Preferably, the driven shaft forms a rotating structure with the bidirectional lead screw via a second conveyor belt, and a rubber pad is provided on the clamping plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This multi-angle adjustable clamp for wire cutting machine tools, through the setting of the clamping mechanism, allows the outer ring to be rotated by gripping the handle. Since the inner ring is fixed on the base, the outer ring can rotate relative to the inner ring by means of rolling balls, thereby driving the mounting plate and the entire clamping part above to rotate, achieving coarse angle adjustment. Then, the cylinder is activated, and its piston rod extends or retracts, driving the connecting seat and the connected connecting rod to move. The connecting rod is connected to the vertical plate, and the other side of the vertical plate is provided with a rotating support and a rotary joint. The connecting rod will push or pull the vertical plate and the entire clamping part to move up and down, thereby allowing for more precise angle adjustment within a certain range. Then, the micro motor is started, driving the first conveyor belt to rotate. The first conveyor belt drives the bidirectional lead screw to rotate. The threads on both sides of the bidirectional lead screw rotate in opposite directions. The matching support plate will move towards or away from each other along the axis of the bidirectional lead screw under the action of the threads. The second conveyor belt and driven shaft provide auxiliary support and transmit power, ensuring that the movement of the clamping plates is more synchronized and stable, and ensuring the clamping effect on the workpiece. The support plate is connected to the clamping plate through a connecting rod. When the support plate moves, it drives the clamping plate to move synchronously. The two clamping plates can clamp the workpiece when they move towards each other, and release the workpiece when they move away from each other. This adapts to the processing needs of complex shaped workpieces, greatly shortens the processing auxiliary time, and improves the overall processing efficiency of the machine tool.

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.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a multi-angle adjustable clamp for a wire cutting machine tool, including a bed 1, a worktable 2 fixedly connected to the upper surface of the bed 1, a processing box 3 fixedly connected to the upper surface of the worktable 2, a base 4 fixedly connected to the inner surface of the processing box 3, a clamping mechanism 5 provided on the upper surface of the base 4, and a cutting system 6 fixedly connected to one side surface of the worktable 2.

[0023] The clamping mechanism 5 includes an inner ring 501, a ball bearing 502, an outer ring 503, a handle 504, a mounting plate 505, a vertical plate 506, a rotating support 507, a rotary joint 508, a clamping base plate 509, a cylinder 510, a connecting seat 511, a connecting rod 512, a micro motor 513, a first conveyor belt 514, a bidirectional lead screw 515, a second conveyor belt 516, a driven shaft 517, a support plate 518, a connecting rod 519, and a clamping plate 520. The inner ring 501 is fixedly connected to the upper surface of the base 4. The ball bearing 502 is fixedly connected to the outer surface of the inner ring 501. The outer ring 503 is fixedly connected to the outer surface of the inner ring 501. A handle 504 is fixedly connected to one side surface of the outer ring 503. A mounting plate 504 is fixedly connected to the upper surface of the outer ring 503. A mounting plate 505 has a vertical plate 506 fixedly connected to its upper surface. A rotating support 507 is fixedly connected to the upper surface of the vertical plate 506. A rotary joint 508 is fixedly connected to one side surface of the rotary support 507. A clamping base plate 509 is fixedly connected to one side surface of the rotary joint 508. A cylinder 510 is fixedly connected to one side surface of the vertical plate 506. A connecting seat 511 is fixedly connected to the upper surface of the cylinder 510. A connecting rod 512 is fixedly connected to one side surface of the connecting seat 511. A micro motor 513 is fixedly connected to the upper surface of the clamping base plate 509. A first conveyor belt 514 is fixedly connected to one side surface of the micro motor 513. A bidirectional lead screw 515 is fixedly connected to the inner surface of the first conveyor belt 514. A second conveyor belt 516 is fixedly connected to one side surface. A driven shaft 517 is fixedly connected to the inner surface of the second conveyor belt 516. A support plate 518 is fixedly connected to one side surface of a bidirectional lead screw 515. A connecting rod 519 is fixedly connected to one side surface of the support plate 518. A clamping plate 520 is fixedly connected to one side surface of the connecting rod 519. The system is connected via an inner ring 501, a ball bearing 502, an outer ring 503, a handle 504, a mounting plate 505, a vertical plate 506, a rotating support 507, a rotary joint 508, a clamping base plate 509, a cylinder 510, a connecting seat 511, a connecting rod 512, a micro motor 513, a first conveyor belt 514, a bidirectional lead screw 515, a second conveyor belt 516, a driven shaft 517, a support plate 518, and a connecting rod 519. The clamping plate 520 is designed so that, during use, the outer ring 503 is rotated by gripping the handle 504. Since the inner ring 501 is fixed to the base 4, the outer ring 503, through the engagement of the rolling ball 502 with the inner ring 501, can rotate relative to the inner ring 501. This, in turn, causes the mounting plate 505 and the entire clamping part above it to rotate, achieving coarse angle adjustment. When the cylinder 510 is activated, its piston rod extends or retracts, driving the connecting seat 511 and the connected connecting rod 512 to move. The upper part of the connecting rod 512 is connected to the upright plate 506. The other side of the upright plate 506 is provided with a rotating support 507 and a rotary joint 508. Thus, the connecting rod 512 pushes or pulls the upright plate 506 and the entire clamping part to move up and down on one side of the cylinder 510, allowing for finer angle adjustment within a certain range.When the micro motor 513 is started, it drives the first conveyor belt 514 to rotate. The first conveyor belt 514 then drives the bidirectional lead screw 515 to rotate. When the bidirectional lead screw 515 rotates, because its two threads rotate in opposite directions, the support plate 518, which cooperates with the bidirectional lead screw 515, will move towards or away from each other along the axial direction of the bidirectional lead screw 515 under the action of the threads. The second conveyor belt 516 and the driven shaft 517 serve to provide auxiliary support and transmit power, ensuring that the movement of the clamping plate 520 is more synchronized and stable, thus guaranteeing the clamping effect on the workpiece. The support plate 518 is connected to the clamping plate 520 through the connecting rod 519. When the support plate 518 moves, it drives the clamping plate 520 to move synchronously. When the two clamping plates 520 move towards each other, they clamp the workpiece; when they move away from each other, they release the workpiece. This adapts to the processing needs of some complex-shaped workpieces, greatly shortens the processing auxiliary time, and improves the overall processing efficiency of the machine tool.

[0024] Furthermore, the outer ring 503 forms a rotating structure with the inner ring 501 through the rolling ball 502. The upper surface of the outer ring 503 is provided with mounting holes. Through the setting of the outer ring 503, in use, the outer ring 503 forms a rotating structure relative to the inner ring 501 with the help of the rolling ball 502, so that the entire clamping mechanism 5 can easily achieve multi-angle rotation adjustment. Whether processing complex workpieces with multiple inclined surfaces or when the workpiece angle needs to be frequently changed according to different processing technology, the operator can conveniently and quickly adjust to the appropriate angle by manually rotating the outer ring 503 without complicated disassembly and reinstallation operations.

[0025] Furthermore, the clamping base plate 509 forms a rotating structure with the rotating support 507 via the rotary joint 508. A sharp-angled locking block is provided on one side of the clamping base plate 509. With the clamping base plate 509, the sharp-angled locking block on one side of the clamping base plate 509 can play a role in precise positioning when clamping the workpiece. When the workpiece is placed on the clamping base plate 509, the sharp-angled locking block can fit with the corresponding part of the workpiece. Through its unique sharp-angled shape, it can accurately lock the position of the workpiece in a specific direction, preventing horizontal displacement of the workpiece during the clamping process and subsequent processing, thus ensuring processing accuracy.

[0026] Furthermore, the upper surface of the upright plate 506 is provided with an acute-angle slot, and two sets of rotating supports 507 are symmetrically arranged around the central axis of the rotating joint 508. With the arrangement of the rotating supports 507, when in use, the two sets of rotating supports 507 work together to share the weight of the clamping base plate 509 and the workpiece, as well as the torque generated during rotation, thus avoiding problems such as uneven rotation and angle deviation caused by unilateral force.

[0027] Furthermore, two sets of connecting seats 511 are symmetrically arranged around the central axis of cylinder 510, and two sets of connecting rods 512 are symmetrically arranged around the central axis of cylinder 510. Through the arrangement of connecting seats 511 and connecting rods 512, when cylinder 510 is working, the force generated by it can be transmitted more evenly to the entire clamping mechanism 5 through these two sets of connecting seats 511. The symmetrically distributed connecting seats 511 avoid structural skewing and uneven force distribution caused by unilateral force.

[0028] Furthermore, the bidirectional lead screw 515 forms a rotating structure with the micro motor 513 via the first conveyor belt 514. The inner wall size of the first conveyor belt 514 matches the outer wall size of the bidirectional lead screw 515. Through the setting of the first conveyor belt 514, the power generated by the micro motor 513 can be effectively transmitted to the bidirectional lead screw 515 during use, reducing the number of intermediate transmission components and reducing energy loss in the power transmission process, thereby ensuring high transmission efficiency.

[0029] Furthermore, the driven shaft 517 forms a rotating structure with the bidirectional lead screw 515 via the second conveyor belt 516. A rubber pad is provided on the clamping plate 520. Through the setting of the clamping plate 520, the rubber pad on the clamping plate 520 can increase the friction between the workpiece and the workpiece during use. When clamping the workpiece, the rubber pad is in close contact with the surface of the workpiece. With its own elasticity and surface characteristics, the workpiece is less likely to slide or shift between the clamping plates 520 when subjected to external force, ensuring that the workpiece can maintain a fixed position throughout the entire processing.

[0030] Working Principle: Based on work requirements, the outer ring 503 is rotated by gripping the handle 504, thanks to the bed 1's configuration. Since the inner ring 501 is fixed to the base 4, the outer ring 503 rotates relative to the inner ring 501 via the ball bearing 502, thus rotating the mounting plate 505 and the entire clamping portion above it, achieving coarse angle adjustment. When the cylinder 510 is activated, its piston rod extends or retracts, driving the connecting seat 511 and its connected connecting rod 512. The connecting rod 512 is connected to the vertical plate 506, and the other side of the vertical plate 506 is equipped with a rotating support 507 and a rotary joint 508. This allows the connecting rod 512 to push or pull the vertical plate 506 and the entire clamping portion up and down on one side of the cylinder 510, enabling finer angle adjustments within a certain range. When the micro motor 513 is activated, it drives the first conveyor belt 514 to rotate, which in turn drives the bidirectional lead screw 515 to rotate. As the bidirectional lead screw 515 rotates... Because the threads on both sides of the screw have opposite directions, the support plate 518, which cooperates with the double-acting lead screw 515, will move towards or away from each other along the axial direction of the double-acting lead screw 515 under the action of the threads. The second conveyor belt 516 and the driven shaft 517 serve to provide auxiliary support and transmit power, ensuring that the movement of the clamping plate 520 is more synchronized and stable, and guaranteeing the clamping effect on the workpiece. The support plate 518 is connected to the clamping plate 520 through the connecting rod 519. When the support plate 518 moves, it will drive the clamping plate 520 to move synchronously. When the two clamping plates 520 move towards each other, they clamp the workpiece; when they move away from each other, they release the workpiece. This adapts to the processing needs of some complex-shaped workpieces, greatly shortens the processing auxiliary time, and improves the overall processing efficiency of the machine tool. This completes the use of a multi-angle adjustable fixture for wire cutting machine tools. The cylinder 510 is model YS-NZ100-12A, and the micro motor 513 is model WL-37RS528.
