[0002] During the machining or heat treatment process of shaft workpieces, bending deformation is inevitable due to the action of external force or thermal stress. These bending deformations must be straightened and corrected, otherwise, it will affect the subsequent precision machining of these shaft workpieces, and it will affect the final machining accuracy of these shaft workpieces, thereby affecting the performance and service life of these shaft workpieces. Generally, they need to be straightened by straightening tooling.

[0003] The existing motor shaft straightening device used in motor production has the following process for straightening the motor shaft: first clamp and fix the motor shaft, then inspect it, and then straighten the bent and deformed parts after inspection.

At the same time, in order to meet the straightening needs of motor shafts of different diameters and lengths, companies may need to purchase multiple straightening devices or fixtures of different specifications. This not only increases the initial investment cost, but may also complicate subsequent maintenance and management, further increasing operating costs. Utility Model Content

DETAILED DESCRIPTION

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] like Figures 1 to 5 As shown, the utility model discloses a straightening device for machining shaft workpieces, which is used for straightening a motor shaft, and comprises a machining table 1, a motor shaft clamping mechanism 2 and a motor shaft straightening mechanism 3. A straightening station is provided on the top of the machining table 1, and the motor shaft clamping mechanism 2 is arranged at the straightening station. The motor shaft clamping mechanism 2 comprises motion components in two directions of Z-axis and X-axis, a rotating component 2c and a pressure rod 2d. The motion component is used to control the precise position and motion trajectory of the rotating component 2c and the pressure rod 2d at the straightening station. The rotating component 2c is used to control the rotation of the pressure rod 2d. The motor shaft straightening mechanism 3 is arranged at the straightening station. The motor shaft straightening mechanism 3 comprises a detection component 3a and a straightening component 3b. The detection component 3a is used to detect the curvature of the motor shaft, and the straightening component 3b is used to straighten the bent part of the motor shaft.

[0027] When it is necessary to straighten motor shafts of different sizes, the operator can adjust the parameters of the Z-axis and X-axis motion components. The Z-axis motion component is responsible for controlling the movement of the rotating component 2c and the pressure rod 2d in the vertical direction to adapt to the diameter changes of motor shafts of different sizes, thereby ensuring that the pressure rod 2d can accurately align with the center position of the motor shaft. The X-axis motion component is responsible for controlling the movement of the rotating component 2c and the pressure rod 2d in the horizontal direction to adapt to the length changes of the motor shaft.

[0028] The utility model uses the motor shaft clamping mechanism 2 to achieve straightening of motor shafts of different specifications during the production and processing of the motor shaft, without the need to frequently replace the fixture or adjustment device to adapt to motor shafts of different sizes, and the operator can complete the straightening work more quickly and efficiently. This not only shortens the straightening cycle of a single workpiece, but also reduces the time wasted due to replacing the fixture or adjustment device, thereby improving the overall production efficiency. At the same time, by clamping motor shafts of different specifications, the enterprise does not need to purchase multiple straightening devices or fixtures of different specifications. This reduces the initial investment cost, and also reduces the complexity of subsequent maintenance and management, which helps the enterprise reduce operating costs.

[0029] Specifically, refer to Figure 2As shown, the moving component in the Z-axis direction is the first moving component 2a, the moving component in the X-axis direction is the second moving component 2b, the second moving component 2b is arranged on the first moving component 2a, the rotating component 2c is arranged on the second moving component 2b, and the pressure rod 2d is arranged on the rotating component 2c.

[0030] When it is necessary to straighten motor shafts of different sizes, the operator can clamp motor shafts of different sizes by adjusting the first motion component 2a and the second motion component 2b. The first motion component 2a is used to control the movement of the rotating component 2c and the pressure rod 2d in the vertical direction to adapt to the diameter changes of motor shafts of different sizes, thereby ensuring that the pressure rod 2d can accurately align with the center position of the motor shaft. The second motion component 2b is used to control the movement of the rotating component 2c and the pressure rod 2d in the horizontal direction to adapt to the length changes of the motor shaft. The rotating component 2c is used to rotate the pressure rod 2d when the motor shaft is straightened by the motor shaft straightening mechanism 3, so that the motor shaft can rotate according to a predetermined trajectory, thereby better cooperating with the straightening component 3b to perform the straightening operation, thereby improving the straightening accuracy and enhancing the versatility and adaptability of the entire device.

[0031] Specifically, refer to Figure 3 As shown, the first motion component 2a includes a fixed frame 2a1 and a movable plate 2a3, the fixed frame 2a1 is provided with a first slide groove 2a2 in a vertical state, and the movable plate 2a3 is provided with a first slider 2a4 that slidably cooperates with the first slide groove 2a2. Through the cooperation between the first slide groove 2a2 and the first slider 2a4, the relative position between the fixed frame 2a1 and the movable plate 2a3 is adjusted, and the movement of the rotating component 2c and the pressure rod 2d in the Z-axis direction is realized to adapt to the diameter change of motor shafts of different sizes, thereby ensuring that the pressure rod 2d can accurately align with the center position of the motor shaft.

[0032] Specifically, refer to Figure 3 As shown, the first motion assembly 2a also includes a first driving member 2a5, which is arranged on the fixed frame 2a1, and the output end of the first driving member 2a5 is fixedly connected to the movable plate 2a3, and the first driving member 2a5 is a telescopic cylinder. When the first driving member 2a5 is started, it will push or pull the movable plate 2a3 through its output end, so that the movable plate 2a3 slides smoothly along the first slide groove 2a2. Through the telescopic action of the telescopic cylinder, the position of the movable plate 2a3 can be easily adjusted, thereby realizing accurate control of the rotating assembly 2c and the pressure rod 2d in the Z-axis direction.

[0033] Specifically, refer to Figure 4As shown, the second motion assembly 2b includes a movable frame 2b1, a second slide groove 2b2 in a horizontal state is provided on the top of the movable plate 2a3, and the movable frame 2b1 is provided with a second slider 2b3 that slidably cooperates with the second slide groove 2b2. Through the cooperation between the second slide groove 2b2 and the second slider 2b3, the relative position between the movable plate 2a3 and the movable frame 2b1 is adjusted, and the movement of the rotating assembly 2c and the pressure rod 2d in the X-axis direction is realized to adapt to the length change of motor shafts of different sizes, thereby ensuring that the motor shaft can be accurately and stably clamped by the pressure rod 2d.

[0034] Specifically, refer to Figure 4 As shown, the second motion assembly 2b also includes a second driving member 2b4, which is arranged on the movable plate 2a3, and the output end of the second driving member 2b4 is fixedly connected to the movable frame 2b1, and the second driving member 2b4 is a telescopic cylinder. When the second driving member 2b4 is started, it will push or pull the movable frame 2b1 through its output end, so that the movable frame 2b1 slides smoothly along the second slide groove 2b2. Through the telescopic action of the telescopic cylinder, the position of the movable plate 2a3 can be easily adjusted, thereby realizing the control of the rotating assembly 2c and the pressure rod 2d in the X-axis direction.

[0035] Specifically, refer to Figure 5 As shown, the rotating assembly 2c includes a rotating motor 2c1, which is arranged on a movable frame 2b1, and the output end of the rotating motor 2c1 is fixedly connected to the pressure rod 2d. As a power source, the rotating motor 2c1 has the characteristics of adjustable speed and stable torque, and can meet different motor shaft rotation requirements. By adjusting the parameters of the rotating motor 2c1, the rotation speed and rotation angle of the motor shaft can be accurately controlled to ensure the accuracy and reliability during the straightening process.

[0036] Specifically, refer to Figure 3 and Figure 4 As shown, the first driving member 2a5 is a hydraulic telescopic cylinder, and the second driving member 2b4 is a pneumatic telescopic cylinder. The hydraulic telescopic cylinder is known for its powerful driving force and stable motion characteristics, and is suitable for occasions that need to bear large loads or require precise control. In the motor shaft clamping mechanism 2, the hydraulic telescopic cylinder serves as the first driving member 2a5, which can ensure the stable and smooth movement of the movable plate 2a3 in the Z-axis direction, thereby achieving precise clamping of motor shafts of different heights. The pneumatic telescopic cylinder has the advantages of fast response speed, flexible movement and relatively low cost, and is particularly suitable for application scenarios with high speed response requirements and relatively light loads. In the motor shaft clamping mechanism 2, the pneumatic telescopic cylinder serves as the second driving member 2b4, which is responsible for driving the movable frame 2b1 to move quickly and accurately in the X-axis direction.
