Description

Technical Field

[0001] This invention relates to the field of motor shaft turning technology, specifically to a motor shaft production turning apparatus. Background Technology

[0002] The motor shaft is the core transmission component of the motor. It is usually made of metal (such as steel or aluminum) and is cylindrical. One end is connected to the motor rotor core, and the other end extends to the outside of the motor. Its core function is to transmit the rotational power of the rotor and output the mechanical energy of the motor to external equipment (such as gears, conveyor belts, pumps, etc.). At the same time, it needs to withstand torque and radial / axial loads, so it has high requirements for precision, strength and wear resistance.

[0003] The motor shaft turning device is a special machine tool used to process motor shafts. It mainly uses CNC or semi-automatic control to complete the turning of the outer circle, steps, threads, keyways and other parts of the motor shaft. It is usually equipped with a special fixture (such as a three-jaw chuck) to fix the workpiece. Combined with the feed motion of the cutting tool, it can achieve high-precision cutting of the motor shaft and ensure that key parameters such as the diameter tolerance and cylindricity of the shaft meet the standards.

[0004] However, in the existing technology, there are two types of workpiece clamping schemes for turning motor shafts. The first is the clamping method using a three-jaw chuck and a single-sided conical mandrel. Although this method can ensure the clamping stability of the motor shaft during turning, the clamping area of ​​the three-jaw chuck will form a machining blind zone. This section of the shaft cannot be turned and requires subsequent secondary clamping or additional processes to make up for it, which reduces the machining efficiency. The second is the clamping method using conical mandrels inserted into pre-made holes in the motor shaft. Although this method can achieve unobstructed machining of the entire shaft, it relies solely on the friction between the conical surface and the hole wall to transmit torque. During the turning process, problems such as slippage and axial movement of the motor shaft are prone to occur, making it difficult to ensure the coaxiality of the shaft rotation, which directly affects the turning dimensional accuracy and surface quality.

[0005] Therefore, we propose a turning device for producing motor shafts. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a turning device for motor shaft production. It solves the problem that while the existing clamping method using a three-jaw chuck and a single-sided conical mandrel ensures clamping stability during motor shaft turning, the clamping area of ​​the three-jaw chuck creates a machining blind spot, preventing the shaft section from being turned. This requires subsequent secondary clamping or additional processes, reducing machining efficiency. The clamping method using conical mandrels inserted into pre-drilled holes in the motor shaft allows for unobstructed machining of the entire shaft area, but relies solely on the friction between the conical surface and the hole wall to transmit torque. This makes it prone to slippage and misalignment of the motor shaft during turning, making it difficult to guarantee shaft rotational coaxiality and directly affecting dimensional accuracy and surface quality.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a motor shaft turning device, comprising a base, a housing mounted on the base, a turning assembly for turning the motor shaft on the base, a guide block fixedly connected to the top inner wall of the housing, two movable arms slidably connected to the surface of the guide block, and conical clamping heads rotatably connected to the inner walls of the two movable arms, a control assembly provided on the inner wall of the housing for controlling the conical clamping heads to insert into pre-drilled holes at both ends of the motor shaft, a rotating device provided inside the housing for controlling the two sets of conical clamping heads to rotate synchronously, and a stabilizing device provided on the surface of the movable arms for clamping and supporting the motor shaft; The stabilizing device includes a hollow ring located on one side of the moving arm. Multiple clamping members for contacting the motor shaft are slidably connected to the inner wall of the hollow ring. A control unit is also provided on the hollow ring for controlling the movement of the multiple clamping members to clamp the motor shaft. A reset unit is provided between the clamping members and the hollow ring. A pushing unit is provided on the moving arm for controlling the movement of the hollow ring to clamp the motor shaft at different positions and switch the turning position.

[0008] Preferably, the clamping member includes a clamping block that is slidably connected to the inner wall of the hollow ring. The inner wall of the clamping block is provided with balls. When the clamping member clamps, the clamping block drives the balls to move. The balls can fit against the surface of the motor shaft. When the motor shaft rotates, the balls cooperate to rotate, reducing wear on both.

[0009] Preferably, the control unit includes a protruding rod fixed in the inner wall of the clamping block. Multiple sets of guide frames are fixedly connected to the surface of the hollow ring, with two guide frames in each set. Worm gears are rotatably connected to the inner walls of the multiple sets of guide frames. Multiple sets of extrusion blocks for extruding the protruding rod are fixedly connected to the inner side of the worm gears. A mounting frame is fixedly connected to the surface of the hollow ring. A worm is rotatably connected to the inner wall of the mounting frame, meshing with the worm gear. A drive motor is mounted on the surface of the mounting frame, and the output end of the drive motor is fixedly connected to one end of the worm. Through these components, when the clamping component is moved, the drive motor is activated, causing the worm to rotate. The worm drives the worm gear to rotate within the guide frame. Simultaneously, the extrusion blocks contact the protruding rod, pushing the clamping component downwards. The rollers in the clamping component contact the motor shaft, achieving clamping support and ensuring stability during turning.

[0010] Preferably, the pushing part includes two sliding rods fixed on the surface of the hollow ring. The sliding rods are slidably connected to the inner wall of the moving arm. Two sets of pushing cylinders are installed on the surface of the moving arm. The output end of the pushing cylinder is fixedly connected to the surface of the hollow ring. Through the above components, during the turning process, when turning both ends of the motor shaft, the pushing cylinder can drive the hollow ring to move to the center position of the motor shaft for clamping. When turning the center position of the motor shaft, the pushing cylinder can drive the hollow ring to move to both ends of the motor shaft for clamping.

[0011] Preferably, the reset part includes two guide rods fixed on the surface of the hollow ring. The guide rods are slidably connected to the inner wall of the clamping block. A reset spring is sleeved on the surface of the guide rod. The two ends of the reset spring are fixedly connected to the surfaces of the clamping block and the hollow ring, respectively. Through the above components, the guide rods can further improve the stability effect when the clamping block moves. At the same time, after the squeezing block loses its squeezing of the protrusion, the reset spring can drive the squeezing block and the ball to perform a reset operation.

[0012] Preferably, the control component includes a bidirectional screw rotatably connected to the inner wall of the housing. The bidirectional screw is threadedly connected to the inner walls of the two moving arms respectively. A control motor is also installed on the surface of the housing. The output end of the control motor is fixedly connected to one end of the bidirectional screw. Through the above components, when clamping the motor shaft, the control motor is turned on, and the control motor drives the bidirectional screw to rotate. The bidirectional screw can drive the two moving arms to move, and the two moving arms drive the conical clamping heads to move, clamping them in the pre-drilled holes at both ends of the motor shaft to realize the clamping operation.

[0013] Preferably, the rotating device includes a rotating shaft rotatably connected to the inner wall of the housing, the rotating shaft passing through two moving arms, a synchronizing cylinder rotatably connected to the inner wall of each moving arm, the synchronizing cylinder being inserted into the inner wall of the moving arm, a synchronizing wheel fixedly connected to the surface of the conical gripping head, and a synchronizing belt installed between the synchronizing cylinder and the synchronizing wheel. Through the above components, the synchronizing cylinder can move on the rotating shaft during the movement of the moving arms. When rotating, the rotating motor is turned on, the rotating motor drives the rotating shaft to rotate, the rotating shaft drives the synchronizing cylinder in the moving arm to rotate, and the synchronizing cylinder, in conjunction with the synchronizing belt, can drive the synchronizing wheel and the conical gripping head to rotate.

[0014] Preferably, the rotating shaft is a cylindrical rod, and the surface of the cylindrical rod has two grooves for inserting the synchronizing cylinder.

[0015] Preferably, the turning assembly includes a guide rail plate fixed to the surface of the machine base, a movable seat slidably connected to the surface of the guide rail plate, a tool holder slidably connected to the surface of the movable seat, and a detachable conductor installed on the tool holder. The turning assembly also includes a control unit for controlling the axial and radial movement of the tool body along the motor shaft. Through the above components, during the turning process, the control unit controls the axial and radial movement of the tool body along the motor shaft to realize the turning operation on the motor shaft.

[0016] Preferably, the control unit includes a drive screw rotatably connected to the inner wall of the guide rail plate, the drive screw being threadedly connected to the inner wall of the movable seat, an auxiliary motor mounted on the surface of the guide rail plate, the output end of the auxiliary motor being fixedly connected to one end of the drive screw, and a control cylinder mounted on the surface of the movable seat, the output end of the control cylinder being fixedly connected to the surface of the tool holder. Through these components, during control operations, the auxiliary motor can drive the drive screw to rotate, the drive screw can drive the movable seat, tool holder, and tool body to move axially along the motor shaft, and the control cylinder can drive the tool holder and tool body to move radially along the motor shaft, thus realizing the turning operation.

[0017] In summary, the technical effects and advantages of this invention are as follows: 1. In this invention, the control component drives two moving arms to work with a tapered clamping head to clamp the motor shaft in pre-drilled holes at both ends, achieving centering clamping. Subsequently, the stabilizing device on the two moving arms can achieve multi-position adaptive clamping support for different positions of the motor shaft. When turning both ends, it is clamped in the center; when turning the center, it is clamped at both ends. This allows the machining area to avoid the support point, effectively limiting the rotation of the motor shaft and the radial runout during the turning process. This ensures that the motor shaft is machined in one go during the turning process, reducing the time loss and errors caused by multiple clamping. It significantly improves machining efficiency while ensuring the dimensional accuracy and coaxiality consistency of each machined part of the motor shaft.

[0018] 2. In this invention, the moving seat of the turning component can move axially along the guide plate through the auxiliary motor and the drive screw, and the tool holder can move radially through the control cylinder, so as to realize the flexible feed of the tool body in the axial and radial directions, which can be adapted to the turning of motor shafts of different lengths and diameters.

[0019] 3. In this invention, the control component drives two moving arms to approach synchronously via a bidirectional screw, so that the conical clamping head is precisely inserted into the pre-drilled holes at both ends of the motor shaft to achieve centering clamping; the drive component drives the two sets of conical clamping heads to rotate synchronously via a rotating shaft, a synchronous cylinder, and a synchronous belt to ensure that the coaxiality is consistent during the rotation of the motor shaft, providing a foundation for high-precision turning.
