Technical Field

[0001] The utility model relates to the technical field of motor shaft processing, in particular to a straightening device for a motor shaft. Background Art

[0002] During the machining or heat treatment of shaft workpieces, due to the action of external forces or thermal stresses, bending deformation will inevitably occur. These bending deformations must be straightened and corrected. Otherwise, it will affect the subsequent precision machining of these shaft workpieces, the final machining accuracy of these shaft workpieces, and thus the service performance and service life of these shaft workpieces.

[0003] Generally, a straightening device is required for straightening. Most straightening devices achieve the straightening of the motor shaft by setting a straightening sleeve. When straightening the motor shaft, a large amount of friction will occur between the straightening sleeve and the surface of the motor shaft, resulting in more scratches on the surface of the motor shaft due to friction, thereby reducing the straightening effect on the motor shaft. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that a large amount of friction will occur between the straightening sleeve and the surface of the motor shaft in the prior art, resulting in more scratches on the surface of the motor shaft due to friction, thereby reducing the straightening effect on the motor shaft, and to propose a straightening device for a motor shaft.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] Design a straightening device for a motor shaft, including a chassis. Two symmetrically arranged clamping blocks are slidably connected to the chassis. Grooves are provided on the opposite sides of the two clamping blocks.

An electric telescopic rod for driving the pressing mechanism to reciprocate horizontally is fixedly connected to the chassis. A lubricating mechanism for reducing the friction between the rotating shaft and the pressing mechanism is fixedly connected to the pressing mechanism.

[0007] Preferably, the distance adjusting mechanism includes two symmetrically arranged mounting plates. The two symmetrically arranged mounting plates are fixedly connected to the bottom end of the chassis. A bidirectional screw rod is rotatably connected to the two symmetrically arranged mounting plates. Threaded holes are provided on each clamping block. The bidirectional screw rod is matched with the two threaded holes. A turntable is fixedly connected to the bidirectional screw rod.

[0008] Preferably, an anti-slip sleeve is sleeved on the turntable.

[0009] Preferably, the pressing mechanism includes a movable frame slidably connected to the chassis. The movable frame is fixedly connected to the telescopic end of the electric telescopic rod. A movable block is slidably connected to the movable frame, and the movable block is fixedly connected to the lubrication mechanism. A threaded rod for driving the movable block to move in the vertical direction is connected to the movable frame. A support member is fixedly connected to the movable frame, and a pressing member is fixedly connected to the movable block. The pressing member cooperates with the support member.

[0010] Preferably, a handle is fixedly connected to the upper end of the threaded rod.

[0011] Preferably, the lubrication mechanism includes a support plate fixedly connected to the support member. A box body is connected to the support plate. A connecting pipe communicates with the bottom end of the box body. A valve is connected to the connecting pipe, and a drip head communicates with the bottom end of the connecting pipe.

[0012] Preferably, the box body is a transparent box.

[0013] The beneficial effects of a motor shaft straightening device proposed by the present utility model are as follows:

[0014] By adjusting the distance between the two clamping blocks through the spacing adjustment mechanism, the two clamping blocks clamp and fix the motor shaft. The motor shaft passes through the pressing mechanism. The lubrication mechanism is opened, and the lubrication mechanism releases lubricating liquid. The lubricating liquid drips onto the surface of the motor shaft.

Specific embodiments

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment 1: Refer to Figure 1-2 , a motor shaft straightening device, including a chassis 1, two symmetrically arranged clamping blocks 2 are slidably connected to the chassis 1, grooves 4 are opened on the opposite sides of the two clamping blocks 2, and a spacing adjustment mechanism 3 for adjusting the distance between the two clamping blocks 2 is connected to the bottom end of the chassis 1. A pressing mechanism 5 is slidably connected to the chassis 1, and an electric telescopic rod 6 for driving the pressing mechanism 5 to reciprocate horizontally is fixedly connected to the chassis 1. A lubricating mechanism 7 for reducing the friction between the rotating shaft and the pressing mechanism 5 is fixedly connected to the pressing mechanism 5.

[0022] Working process:

[0023] The two ends of the motor shaft are respectively inserted into different grooves 4, the spacing adjustment mechanism 3 is rotated, and the distance between the two clamping blocks 2 is adjusted through the spacing adjustment mechanism 3, so that the two clamping blocks 2 clamp and fix the motor shaft. The motor shaft passes through the pressing mechanism 5, the lubricating mechanism 7 is opened, the lubricating mechanism 7 releases the lubricating liquid, and the lubricating liquid drips onto the surface of the motor shaft. After the electric telescopic rod 6 is powered on and started, it drives the pressing mechanism 5 to reciprocate horizontally. During the movement of the pressing mechanism 5, the motor shaft is straightened. Since the surface of the motor shaft is coated with the lubricating liquid, the friction received during the straightening process of the pressing mechanism 5 is reduced, thereby reducing the friction received during the straightening process of the motor shaft, and further improving the straightening effect of the motor shaft.

[0024] Embodiment 2: In Embodiment 1, when adjusting the distance between the two clamping blocks 2, it is inconvenient to adjust the clamping blocks 2. Refer to Figure 2, as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the spacing adjustment mechanism 3 includes two symmetrically arranged mounting plates 31. The two symmetrically arranged mounting plates 31 are fixedly connected to the bottom end of the chassis 1. A bidirectional screw 32 is rotatably connected to the two symmetrically arranged mounting plates 31. A threaded hole is formed in each clamping block 2. The bidirectional screw 32 is matched with the two threaded holes. A turntable 33 is fixedly connected to the bidirectional screw 32. An anti-slip sleeve is sleeved on the turntable 33. By rotating the turntable 33, the turntable 33 drives the bidirectional screw 32 to rotate. After the bidirectional screw 32 rotates, the distance between the two clamping blocks 2 is adjusted, and the clamping blocks 2 are convenient to adjust.

[0025] Embodiment 3: In Embodiment 1, when straightening the motor shaft, it is impossible to quickly wrap the outer side of the motor shaft. Refer to Figure 3 , as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the pressing mechanism 5 includes a movable frame 51. The movable frame 51 is slidably connected to the chassis 1. The movable frame 51 is fixedly connected to the telescopic end of the electric telescopic rod 6. A movable block 52 is slidably connected to the movable frame 51. The movable block 52 is fixedly connected to the lubricating mechanism 7.

A support member 54 is fixedly connected to the movable frame 51. A pressing member 55 is fixedly connected to the movable block 52. The pressing member 55 is matched with the support member 54. The support member 54 contacts the bottom end of the motor shaft. By rotating the threaded rod 53, after the threaded rod 53 rotates, the movable block 52 moves downward. The movable block 52 drives the pressing member 55 to move downward. After the pressing member 55 moves downward for a certain distance, it contacts the upper end of the motor shaft. The pressing member 55 and the support member 54 cooperate to form a ring sleeve. The electric telescopic rod 6 drives the movable frame 51 to move. The movable frame 51 drives the pressing member 55 and the support member 54 to move. After the pressing member 55 and the support member 54 move, the motor shaft is pressed and straightened. After the pressing member 55 and the support member 54 cooperate, the outer side of the motor shaft is quickly wrapped.

[0026] Embodiment 4: In Embodiment 1, after the lubricating mechanism 7 releases the lubricating liquid, too much lubricating liquid is released, resulting in waste. Refer to Figure 3 , as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the lubricating mechanism 7 includes a support plate 71. The support plate 71 is fixedly connected to the support member 54. A box body 72 is connected to the support plate 71. The box body 72 is a transparent box. A connecting pipe 73 is communicated with the bottom end of the box body 72. A valve 74 is connected to the connecting pipe 73. The bottom end of the connecting pipe 73 is communicated with a drip head. By opening the valve 74, the lubricating liquid in the box body 72 falls into the connecting pipe 73. The lubricating liquid in the connecting pipe 73 is dripped and released through the drip head, and the lubricating liquid is slowly dripped on the surface of the motor shaft, without causing waste of the lubricating liquid.

[0027] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
