For some irregularly shaped cutting tools, the mechanical jaws may not be able to fully fit the cutting tool surface, causing the cutting tool to wobble during machining, affecting machining accuracy and quality. Moreover, the fixture may require complex adjustments and operations when clamping cutting tools, which not only increases the workload of operators but also prolongs the clamping time and reduces production efficiency.

A rotating rod is movably connected inside the mounting base. A first rotating gear and a second rotating gear are fixedly connected to the output end of one side of the rotating rod. A chain is meshed with the outer surfaces of the first rotating gear and the second rotating gear. A mechanical claw is rotatably arranged inside the groove, and the mechanical claw is fixedly connected to the output end of the rotating rod. A buffer pad is fixedly connected to the inner surface of the output gripper of the mechanical claw.

[0007] Preferably, the clamping mechanism includes a first air pump, which is fixedly connected inside the mounting slot.

[0009] Beneficial effects

[0010] This utility model provides a fixture for blade manufacturing. Compared with the prior art, it has the following advantages:

[0011] (1) The driving mechanism consists of a fixed plate, connecting seat, placement plate, limiting block, second air pump, second air rod, moving plate, second slide rail, sliding plate, toothed plate, meshing gear, coupling, and rotating shaft. The second air pump uses air pressure to extend and retract the second air rod, thereby moving the moving plate and sliding plate back and forth. The limiting block on one side of the placement plate can limit the position of the moving plate, and the sliding plate will move along the second slide rail, thereby moving the toothed plate back and forth. The back and forth movement of the toothed plate will mesh with the meshing gear, thereby driving the coupling and rotating shaft to rotate, thereby driving the rotating rod to rotate the transmission mechanism. The transmission mechanism consists of a mounting seat, rotating rod, first rotating gear, second rotating gear, chain, mechanical claw, and buffer pad. While the rotating shaft drives the rotating rod to rotate, the transmission mechanism drives the first rotating gear and the second rotating gear to drive through the chain. The first transmission gear will drive the rotating rod to drive, thereby rotating the mechanical claw. The mechanical claw will then move the blade. The machine grips the blade, and during the rotation of the mechanical gripper, it can also flip the blade, making it easier for workers to process the back of the blade. The clamping mechanism consists of a first air pump, a first air rod, an adjusting plate, and a placement slot. The first air pump uses air pressure to extend and retract the first air rod, causing the adjusting plate to move along the first slide rail. As the adjusting plate moves, it compresses the reset mechanism composed of a reset spring and a limit plate, causing the adjusting plate to press down on the limit plate and move forward. The reverse movement of the adjusting plate is restricted by the limit plate, allowing the placement slot to be adjusted according to the size of the blade. The buffer pad provides cushioning and shock absorption, preventing direct rigid contact between the blade and the mechanical gripper, thus reducing the possibility of scratches, indentations, and other damage to the blade surface, ensuring the appearance quality and subsequent performance of the blade. It can also effectively disperse the clamping force, preventing the blade from breaking due to excessive local pressure, and improving the integrity of the blade and the yield rate during processing.

[0016] 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.

[0017] Example 1:

[0018] Please see Figure 1-3As shown, this embodiment proposes a fixture for blade manufacturing. The blade fixture includes: a base 1, threaded grooves 101 on the left and right sides of the upper surface of the base 1, mounting brackets 102 fixedly connected to the left and right sides of the upper surface of the base 1, mounting grooves 103 on the outer surface of the mounting brackets 102, and through holes 104 on the inner surface of the mounting brackets 102, which are connected to the mounting grooves 103. A connecting plate 105 is fixedly connected to one side of the mounting brackets 102, a groove 106 is formed inside the connecting plate 105, a return spring 107 is movably connected to one side of the inner surface of the groove 106, and a limit plate 108 is movably connected to the output end of one side of the return spring 107. First slide rails 109 are fixedly connected to the left and right sides of the upper surface of the connecting plate 105. A transmission mechanism and a drive mechanism are arranged sequentially from right to left on one side of the connecting plate 105. A clamping mechanism is provided inside the mounting grooves 103. Bolts are used to align the threaded grooves 101 to install the base 1 onto the placement table. The initial state of the return spring 107 and the limiting plate 108 is a vertical plate shape. Driven by the first air pump 3 and the first air rod 301, 302 presses the vertical limiting plate 108 downwards, causing the limiting plate 108 to extend forward along the first slide rail 109. Conversely, when the first air pump 3 and the second air rod 301 are not working, the vertical limiting plate 108 initially limits the top of one side of the adjusting plate 302. As the clamping mechanism operates, the adjusting plate 302 presses the limiting plate 108 downwards, causing... The adjusting plate 302 passes over the upper surface of the limiting plate 108, and the return spring 107 resets the limiting plate 108. Conversely, when the first air pump 3 and the first air rod 301 return the adjusting plate 302 to its original position, the limiting plate 108 moves backward in the opposite direction, just like during extension and retraction, so that the adjusting plate 302 is reset to its initial state, and the return spring 107 resets the limiting plate 108. The tail side of the adjusting plate 302 in the working state is blocked by the limiting plate 108.

[0019] Preferably, the transmission mechanism includes a mounting base 2. Mounting bases 2 are fixedly connected to the upper and lower sides of the left and right sides of the connecting plate 105. A rotating rod 201 is movably connected inside the mounting base 2. A first rotating gear 202 and a second rotating gear 203 are fixedly connected to the output end of one side of a pair of rotating rods 201. A chain 204 is meshed with the outer surfaces of the first rotating gear 202 and the second rotating gear 203. A mechanical claw 205 is rotatably arranged inside the groove 106, and the mechanical claw 205 is fixedly connected to the output end of the rotating rod 201. A buffer pad 206 is fixedly connected to the inner surface of the output gripper of the mechanical claw 205. The rotating rod 201 is rotated by the drive mechanism, thereby causing the first rotating gear 202 and the second rotating gear 203 to rotate synchronously through the chain 204, thereby causing the mechanical claw 205 to rotate, so that the blade is flipped on the other side that needs to be processed. The buffer pad 206 can effectively disperse the clamping force for some thin or fragile blades, preventing the blade from breaking due to excessive local pressure.

[0020] Preferably, the clamping mechanism includes a first air pump 3. The first air pump 3 is fixedly connected inside the mounting groove 103. A first air rod 301 is movably provided at the air outlet on one side of the first air pump 3 via a quick-connect connector. An adjusting plate 302 is fixedly connected to the output end on one side of the first air rod 301. A placement groove 303 is provided on the side of the adjusting plate 302 near the mechanical gripper 205. Moreover, the first air pump 3 drives the first air rod 301 to adjust the adjusting plate 302, so that the placement groove 303 inside the adjusting plate 302 can be adjusted according to the size of the blade.

[0021] Preferably, the drive mechanism includes a fixed plate 4, a connecting plate 105 is fixedly connected to the side of the connecting plate 105 near the first slide rail 109, a connecting seat 401 is fixedly connected to one side of the fixed plate 4, a placement plate 402 is fixedly connected to one side of the fixed plate 4, limit blocks 403 are fixedly connected to the left and right sides of one side of the placement plate 402, a second air pump 404 is fixedly connected to the upper surface of the placement plate 402 through the connecting seat 401, a second air rod 405 is movably disposed at the air outlet of one side of the second air pump 404 through a quick-connect fitting, a moving plate 406 is fixedly connected to the output end of one side of the second air rod 405, a second slide rail 407 is fixedly connected to the lower surface of the placement plate 402, a sliding plate 408 is fixedly connected to one side of the lower surface of the moving plate 406 and the sliding plate 408 is slidably connected to the second slide rail 407, a locking plate 409 is fixedly connected to the lower surface of the sliding plate 408 and one side of the locking plate 409 is engaged. A meshing gear 4010 is connected, and the meshing gear 4010 is fixedly connected to the output end of one side of the rotating rod 201. A coupling 4011 is fixedly connected to one side of the meshing gear 4010, and a rotating shaft 4012 is fixedly connected to one side of the coupling 4011. Since the second air pump 404 drives the second air rod 405 through air pressure, the second air pump 404 drives the moving plate 406 to move, thereby the moving plate 406 drives the sliding plate 408 to move. The sliding plate 408 will move along the second slide rail 407 for positioning. The limiting blocks 403 on the left and right sides of the placement plate 402 will limit the size of the movement of the moving plate 406. Since the toothed plate 409 will mesh with the meshing gear 4010 while the sliding plate 408 is moving, the meshing gear 4010 will drive the rotating rod 201, the coupling 4011 and the rotating shaft 4012 to drive the transmission mechanism.

[0022] In use, when the fixture is in its initial state, the mechanical claw 205 is in the open state, the return spring 107 is in the naturally extended state, the limiting plate 108 is in a suitable position under the action of the return spring 107, the first air rod 301 and the second air rod 405 are both in the retracted state, the adjusting plate 302 maintains a certain distance from the mechanical claw 205, the moving plate 406 is in the initial position, the toothed plate 409 is not engaged with the meshing gear 4010, the operator places the cutting tool to be processed in a suitable position in the placement groove 303 inside the adjusting plate 302, and prepares for clamping operation. The second air pump 404 in the drive mechanism is started, and the second air pump 404 works, its air outlet inflates the second air rod 405 through the quick-connect connector. Under air pressure, the two air rods 405 gradually elongate, pushing the moving plate 406 forward. The sliding plate 408 on the lower surface of the moving plate 406 slides along the second slide rail 407. As the moving plate 406 moves, the toothed plate 409 on its lower surface begins to mesh with the meshing gear 4010. The meshing gear 4010 begins to rotate under the drive of the toothed plate 409. Since the meshing gear 4010 is connected to the rotating rod 201 through the coupling 4011 and the rotating shaft 4012, the rotating rod 201 also rotates. The rotation of the rotating rod 201 drives the first rotating gear 202 and the second rotating gear 203 to rotate. The first rotating gear 202 and the second rotating gear 203 achieve synchronous transmission through the chain 204, and the rotation of the rotating rod 201... The rotation further drives the mechanical gripper 205 to rotate, and the mechanical gripper 205 gradually closes, clamping the blade placed in the appropriate position. The buffer pad 206 fixedly connected to the inner surface of the output gripper 205 can buffer and protect the blade, preventing damage to the blade during clamping. While the mechanical gripper 205 is clamping the blade, the first air pump 3 in the clamping mechanism is activated. The first air pump 3 operates, and its air outlet inflates the first air rod 301 through a quick-connect connector. The first air rod 301 gradually extends, pushing the adjusting plate 302 forward. The placement groove 303 opened on the side of the adjusting plate 302 near the mechanical gripper 205 can cooperate with the blade to further position and fix the blade, ensuring the positional accuracy of the blade in the fixture. 2. During the movement, the limiting plate 108 restricts the movement of the adjusting plate 302 under the action of the return spring 107, so that the adjusting plate 302 can be adjusted according to the size of the blade. After the processing is completed, the first air pump 3 and the second air pump 404 are turned off. The first air rod 301 gradually retracts under the action of the first air pump 3, driving the adjusting plate 302 to reset. The second air rod 405 retracts under the action of the second air pump 404, pulling the moving plate 406 to move backward. The toothed plate 409 disengages from the meshing gear 4010. The rotating rod 201 drives the mechanical claw 205 to rotate in the opposite direction, causing the mechanical claw 205 to open and release the blade. The operator can then take out the processed blade, and the fixture returns to its initial state, waiting for the next processing operation.
