Description

Technical Field

[0001] This utility model relates to the technical field of rotor processing clamping devices, and in particular to a rotor processing clamping device. 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 often used to clamp rotors.

[0003] The inventors discovered during routine use of the chuck that when the chuck clamps the rotor for processing, it may shift during the processing because the chuck is placed directly on the surface of the worktable. This can make it difficult to process the rotor and cause problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rotor processing clamping device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotor processing clamping device, including a chuck, a pipe fixedly connected to the side of the chuck, a piston fixedly connected inside the chuck, a jaw provided inside the chuck, and a fixing device provided at the bottom of the chuck, the fixing device including a hollow rod fixedly connected to the bottom of the chuck, and a suction cup fixedly connected to the bottom of the hollow rod.

[0006] The effect achieved by the above components is as follows: under the action of the suction cup, the chuck can be fixed on the surface of the operating table, thereby avoiding the displacement of the chuck. When it is necessary to clamp the rotor, the rotor is inserted into the inside of the chuck, the air pump is connected to the pipeline, and the gas is compressed into the inside of the piston, which in turn squeezes the jaws to retract inward, thereby fixing the rotor inside the chuck, thus achieving the function of clamping the rotor.

[0007] Preferably, a sleeve rod is fixedly connected to the side of the hollow rod, a retaining ball is provided inside the sleeve rod, and a circular plate is fixedly connected to the surface of the retaining ball.

[0008] The effect achieved by the above components is that, under the action of the ball and the circular plate, gas will not enter the interior of the suction cup from the position between the ball and the sleeve.

[0009] Preferably, a baffle is fixedly connected to the inner wall of the sleeve rod, a spring is fixedly connected to the side of the baffle, and the other end of the spring is fixedly connected to the surface of the ball.

[0010] The effect achieved by the above components is that, under the action of the spring, the ball can be retracted into the inside of the sleeve, thus preventing the ball from slipping out of the inside of the sleeve.

[0011] Preferably, a film is fixedly connected to the bottom of the suction cup.

[0012] The aforementioned components achieve the following effects: The film allows the suction cup to adhere to the surface of the worktable, preventing gas from entering the suction cup through the gap between it and the worktable, thus preventing chuck displacement. When the chuck needs to be fixed, the suction cup is pressed against the worktable surface, and the chuck is pressed down, causing the gas to push out the ball, thereby venting the gas inside the suction cup. The film again ensures the suction cup adheres to the worktable surface, preventing gas from entering the suction cup through the gap between it and the worktable, thus preventing chuck displacement. After the gas inside the suction cup is vented, the spring causes the ball to retract into the sleeve, preventing it from slipping out. The interaction between the ball and the circular plate prevents gas from entering the suction cup through the gap between the ball and the sleeve, thus fixing the suction cup to the worktable surface and securing the chuck.

[0013] Preferably, the surface of the pipeline is provided with a connecting device, the connecting device including a connecting pipe inserted into the pipeline, a retaining ring fixedly connected to the surface of the connecting pipe, and an annular groove opened inside the pipeline, both the retaining ring and the annular groove being conical rings.

[0014] The effect achieved by the above components is that, under the action of the retaining ring and the ring groove, the connecting pipe can be fixed inside the pipeline, thereby achieving the connection function.

[0015] Preferably, a fixing plate is fixedly connected to the surface of the connecting pipe, a clamp is fixedly connected to the surface of the pipe, a ring is provided on the surface of the clamp, the inner wall of the ring is trapezoidal, and a threaded groove is provided on the surface of the clamp.

[0016] The effect achieved by the above components is that, under the action of the screw groove, the ring can be fixed on the surface of the clamp, thereby achieving the function of connecting the air pump.

[0017] Preferably, an L-shaped plate is fixedly connected to the side of the clip, and the ring is sleeved on the surface of the L-shaped plate.

[0018] The effect achieved by the above components is that, under the action of the L-shaped plate, the ring will not slip off the surface of the clamp, thus avoiding slippage.

[0019] Preferably, a magnetic ring is fixedly connected to the side of the fixing plate, and the magnetic ring is magnetically connected to the clip.

[0020] The aforementioned components achieve the following effects: Under the action of the magnetic ring, the clamp can be fixed to the side of the fixing plate, thus achieving a fixing function. When it is necessary to connect the pipeline to the air pump, the connecting pipe connected to the side of the air pump is inserted into the inside of the pipeline. Under the action of the retaining ring and the ring groove, the connecting pipe can be fixed inside the pipeline, thus achieving a connection function. Rotating the ring on the surface of the clamp causes the clamp to retract towards the center, thus causing the clamp to lock onto the side of the fixing plate. Under the action of the magnetic ring, the clamp can be fixed to the side of the fixing plate, thus achieving a fixing function. Under the action of the screw groove, the ring can be fixed to the surface of the clamp, thus achieving the function of connecting the air pump. When the ring separates from the clamp, under the action of the L-shaped plate, the ring will not slip off the surface of the clamp, thus avoiding slippage and achieving the function of connecting the pipeline.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting a fixing device, when the chuck needs to be fixed, the suction cup is pressed against the surface of the operating table, and the chuck is pressed down, causing the gas to push out the chuck ball, thereby venting the gas inside the suction cup. Under the action of the film, the suction cup can be adhered to the surface of the operating table, preventing gas from entering the suction cup from between the suction cup and the operating table and causing the chuck to shift. After the gas inside the suction cup is vented, under the action of the spring, the chuck ball can retract into the sleeve rod, thus preventing the chuck ball from sliding out of the sleeve rod. Under the action of the chuck ball and the circular plate, gas is prevented from entering the suction cup from between the chuck ball and the sleeve rod, thereby fixing the suction cup to the surface of the operating table and thus fixing the chuck. This achieves the fixing function and solves the problem that after the chuck clamps the rotor for processing, it may shift during rotor processing because the chuck is placed directly on the surface of the operating table.

[0024] Example 1, such as Figure 1 A rotor processing clamping device includes a chuck 1, a pipe 6 fixedly connected to the side of the chuck 1, a piston 5 fixedly connected inside the chuck 1, a jaw 4 provided inside the chuck 1, and a fixing device 2 provided at the bottom of the chuck 1.

[0025] Working principle: When the rotor needs to be clamped, the rotor is inserted into the chuck 1, the air pump is connected to the pipeline 6, and the gas is compressed into the piston 5, which in turn squeezes the jaws 4 to retract inward, thereby fixing the rotor inside the chuck 1, thus achieving the function of clamping the rotor.

[0026] Reference Figure 2 The fixing device 2 includes a hollow rod 21 fixedly connected to the bottom of the chuck 1. A suction cup 22 is fixedly connected to the bottom of the hollow rod 21. A sleeve rod 24 is fixedly connected to the side of the hollow rod 21. A retaining ball 26 is provided inside the sleeve rod 24. A circular plate 27 is fixedly connected to the surface of the retaining ball 26. A baffle 25 is fixedly connected to the inner wall of the sleeve rod 24. A spring 28 is fixedly connected to the side of the baffle 25. The other end of the spring 28 is fixedly connected to the surface of the retaining ball 26. A film 23 is fixedly connected to the bottom of the suction cup 22.

[0027] Working principle: When it is necessary to fix the chuck 1, press the suction cup 22 onto the surface of the operating table and press the chuck 1 down, causing the gas to push out the chuck ball 26, thereby venting the gas inside the suction cup 22. Under the action of the film 23, the suction cup 22 can be adhered to the surface of the operating table, preventing gas from entering the interior of the suction cup 22 from between the suction cup 22 and the operating table, thus preventing the chuck 1 from shifting. After the gas inside the suction cup 22 is vented, under the action of the spring 28, the chuck ball 26 can retract into the sleeve 24, thus preventing the chuck ball 26 from sliding out of the sleeve 24. Under the action of the chuck ball 26 and the circular plate 27, gas is prevented from entering the interior of the suction cup 22 from between the chuck ball 26 and the sleeve 24, thereby fixing the suction cup 22 to the surface of the operating table, thus fixing the chuck 1, and achieving the fixing effect.

[0028] Reference Figure 3The surface of the pipe 6 is provided with a connecting device 3, which includes a connecting pipe 33 inserted into the pipe 6. A retaining ring 35 is fixedly connected to the surface of the connecting pipe 33. An annular groove is opened inside the pipe 6. Both the retaining ring 35 and the annular groove are conical rings. A fixing plate 32 is fixedly connected to the surface of the connecting pipe 33. A clamp 31 is fixedly connected to the surface of the pipe 6. A circular ring 36 is provided on the surface of the clamp 31. The inner wall of the circular ring 36 is trapezoidal. A screw groove 37 is opened on the surface of the clamp 31. An L-shaped plate 38 is fixedly connected to the side of the clamp 31. The circular ring 36 is sleeved on the surface of the L-shaped plate 38. A magnetic ring 34 is fixedly connected to the side of the fixing plate 32. The magnetic ring 34 is magnetically connected to the clamp 31.

[0029] Working principle: When it is necessary to connect pipeline 6 to the air pump, the connecting pipe 33 connected to the side of the air pump is inserted into the interior of pipeline 6. Under the action of the retaining ring 35 and the ring groove, the connecting pipe 33 can be fixed inside the pipeline 6, thus achieving the connection. The ring 36 is rotated on the surface of the clamp 31, thereby retracting the clamp 31 towards the center, thus making the clamp 31 clamped on the side of the fixing plate 32. Under the action of the magnetic ring 34, the clamp 31 can be fixed on the side of the fixing plate 32, thus achieving the fixation. Under the action of the screw groove 37, the ring 36 can be fixed on the surface of the clamp 31, thus achieving the connection of the air pump. When the ring 36 is separated from the clamp 31, under the action of the L-shaped plate 38, the ring 36 will not slip off the surface of the clamp 31, thus avoiding slippage, thereby achieving the connection of pipeline 6.
