The design of this clamp fully considers the complex geometry and high precision requirements of the shell, and it is an indispensable important auxiliary tool in the motor manufacturing field.

[0003] The rail traction motor casting machine shell, also known as the machine base or shell, is a key component in the rail traction motor, which is usually cast from high-quality ductile cast iron and other materials, with sufficient mechanical strength and rigidity, used to fix and support other internal components of the motor, such as the stator core, etc.

[0004] Clamping force plays a crucial role in preventing the deformation of the rail traction motor casting machine shell during machining. Specifically, applying appropriate clamping force is necessary to ensure the stability of the shell during machining. However, the control of this force needs to be extremely precise.

Conversely, if the clamping force is too small, the shell cannot be firmly fixed, making it prone to movement or vibration during machining, which can also lead to machining errors or shell deformation. Therefore, a rail traction motor casting machine shell anti-deformation machining clamp and its use method are proposed to address the above problems. SUMMARY

[0042] As a further implementation of this solution, a rotating groove is provided on the inner side of the lower end of the folding clamping arm 35.

The spring plates 37 are rectangular in shape. A rotating hole is provided on the inner side of the inner hole ear seat 39. The outer side of the shaft rod 42 is rotatably connected to the inner side of the inner hole ear seat 39. The rotating groove design at the lower end of the folding clamping arm 35 and the corresponding configuration of multiple rollers 36 and spring plates 37 enable the clamping mechanism to rotate flexibly and adapt to the clamping requirements of housings of different shapes and sizes. The rectangular spring plates 37 and the rotatably connected shaft rod 42 further enhance the stability and reliability of the clamping.

[0043] As a further implementation of this solution, each group of linear springs 38 consists of four linear springs 38. The linear springs 38 have an inclined structure. One end of the linear spring 38 is fixedly connected to one side of the connecting plate 43. The linear springs 38 are located at both ends of the inner hole lugs 39, which are located between the two fixed shaft lugs 41. The inclined structure of the linear springs 38 allows the clamping force to be evenly distributed on the surface of the housing, reducing local pressure concentration and protecting the housing from damage. At the same time, the configuration of four linear springs 38 improves the stability of the clamping and ensures the stability during the processing.

[0044] As a further implementation of this solution, the shaft rod 42 is cylindrical, the fixed shaft lug 41 is rectangular, the fixed shaft lug 41 is fixedly connected to both ends of the shaft rod 42, and the inner groove spring shell 44 is fixedly connected to one side of both ends of the connecting plate 43. The cylindrical shaft rod 42 and the rectangular fixed shaft lug 41, as well as the hollow inner groove spring shell 44, make each component modular, easy to disassemble and replace, and reduce maintenance costs and time. At the same time, the shaft hole design improves the connection accuracy and stability between components.

[0045] As a further implementation of this solution, the inner groove spring shell 44 is hollow inside, and a shaft hole is opened on the inner side of the upper end of the inner groove spring shell 44. A shaft hole is also opened on the inner side of the upper end of the adjusting convex shell 45. The shaft hole of the adjusting convex shell 45 and the shaft hole of the inner groove spring shell 44 are on the same vertical line. The lower end of the adjusting convex shell 45 is a through structure. A straight hole is opened on the inner side of the adjusting convex shell 45 near the operating lever 48. The outer side of the operating lever 48 is slidably connected to the inner side of the shaft hole of the adjusting convex shell 45. One end of the one-way toothed slide plate 47 is shaped like a right-angled triangular trapezoid. The one-way toothed slide plate 47 meshes with the ratchet 54. The vertical rotating column 53 is rotatably connected to the inner side of the inner groove spring shell 44. The straight hole and through structure design of the adjusting convex shell 45, as well as the precise meshing of the one-way toothed slide plate 47 and the ratchet 54, make the adjustment of the clamping force more flexible and precise. This design allows the operator to quickly adjust the clamping force according to actual needs, improving work efficiency and processing accuracy.

[0046] As a further implementation of this scheme, the second spring 52 is located inside the inner groove spring shell 44. One end of the second spring 52 moves inside the outlet groove 49 opened in the inner groove spring shell 44. There are two second springs 52 in each group. The second springs 52 are fixedly connected to both sides of the synthetic rubber clamping plate 51. One side of the synthetic rubber clamping plate 51 is in close contact with the outside of the motor casting housing body 1. There are three synthetic rubber clamping plates 51. The motor casting housing body 1 is placed on the upper end of the operating table 26. The elastic movement design of the second spring 52 inside the inner groove spring shell 44 provides buffer protection for the clamping process, preventing damage to the housing due to excessive clamping force. At the same time, the fixed connection between the second spring 52 and the synthetic rubber clamping plate 51 enhances the stability of the clamping, ensuring the accuracy and product quality during the processing.

[0047] Workflow: To achieve rapid clamping of the motor casting housing 1 and prevent damage to the motor casting housing 1 during clamping, the first spring spring 34 exerts a constant rotational force on the shaft roller 33 under its elastic torque. The shaft roller 33 is rotatably connected to the inner side of the shaft rotation groove 32 opened in the fixed arm frame 31, which limits the movement of the shaft roller 33 and improves the stability of the folded clamping arm 35 during rotation. The shaft roller 33 drives the folded clamping arm 35 and the roller 36 to rotate, so that the outer side of the roller 36 remains in contact with the lower end of the notched cone 24, while the upper part of the folded clamping arm 35 expands outward and the upper folded clamping arms 35 are spaced apart, making it easier to place the motor casting housing 1 on the operating table. At the upper end of 26, the electric telescopic rod 23 is activated, which drives the notched cone 24 to move downward. The notched cone 24 moves inside the movable groove 22, and the notched cone 24 squeezes the roller 36. When the notched cone 24 moves, it squeezes the roller 36, and the roller 36 rotates inside the folded clamping arm 35. The roller 36 drives the folded clamping arm 35 to rotate around the shaft roller 33. At this time, the folded clamping arm 35 drives the fixed spring plate 37 at the top to move closer to the motor casting housing body 1. The fixed spring plate 37 drives the stabilizing shell assembly 4 and the clamping adjustment assembly 5 to move as a whole, so that the three synthetic rubber clamping plates 51 simultaneously clamp the outside of the motor casting housing body 1, achieving the effect of quickly clamping the motor casting housing body 1. When the synthetic rubber After the clamping plate 51 is attached to the motor casting housing body 1, the inner groove spring shell 44 and the adjusting convex shell 45 of the synthetic rubber clamping plate 51 rotate at a certain angle. The inner groove spring shell 44 drives the connecting plate 43 to rotate, and the connecting plate 43 drives the fixed shaft lug 41 and the shaft rod 42 to rotate. The shaft rod 42 is rotatably connected to the inner side of the inner hole lug 39. The connecting plate 43 compresses or stretches the four linear springs 38. This structure allows the synthetic rubber clamping plate 51 to fit against the outer side of the motor casting housing body 1 over a larger area, thereby dispersing the pressure of the synthetic rubber clamping plate 51 on the motor casting housing body 1, and improving the stability of clamping the motor casting housing body 1. The operation is convenient and quick, and the clamping efficiency is high. To prevent damage to the motor casting housing body 1 during clamping, the aforementioned synthetic rubber clamp 51 is tightly attached to the outer side of the motor casting housing body 1. At this time, the synthetic rubber clamp 51 pulls on the second springs 52 fixed on both sides, causing the second springs 52 to elastically extend. Under the torque of the second springs 52, the synthetic rubber clamp 51 provides a buffering effect when clamping the motor casting housing body 1. Simultaneously, the torque of the second springs 52 increases the friction between the synthetic rubber clamp 51 and the motor casting housing body 1, further improving the stability of the clamping. The synthetic rubber clamp 51 is made of nitrile rubber, which has good elasticity and strength. After being attached to the motor casting housing body 1...It will deform to a certain extent according to the shape of the motor casting housing body 1, thereby protecting the motor casting housing body 1 from damage and improving the stability of clamping the motor casting housing body 1;

[0048] To adjust the clamping force on the motor casting housing 1 to accommodate different materials, the connecting piece 55 is rotated. This rotation drives the ratchet 54 and the vertical rotating column 53 to rotate. The vertical rotating column 53 is rotatably connected to the inner side of the inner groove spring shell 44, limiting its rotation. During rotation, the second spring 52 is wound up, reducing its elastic travel distance. According to Hooke's Law, an increase in the elastic travel distance of the second spring 52 reduces the elastic tension on the synthetic rubber clamping plate 51, while a decrease in the elastic travel distance increases the elastic tension. This allows control over the clamping force of the synthetic rubber clamping plate 51 on the motor casting housing 1, adapting to different motor castings. When the housing body 1 is clamped in operation, the ratchet 54 rotates, which pushes the one-way toothed slide plate 47 to move. According to the tooth shape of the one-way toothed slide plate 47 and the ratchet 54, after the one-way toothed slide plate 47 is engaged with the ratchet 54, the vertical rotating column 53 rotates when winding the second spring 52. Under the action of the elastic force of the spring extension rod 46, the one-way toothed slide plate 47 is kept engaged with the outer side of the ratchet 54. It is necessary to loosen the second spring 52, which is also the elastic movement of the second spring 52. When the distance increases, the operating lever 48 is pulled, which drives the one-way toothed slide plate 47 to move. When the one-way toothed slide plate 47 engages with the ratchet 54, the vertical rotating column 53 rotates inside the inner groove spring shell 44 under the torque of the second spring spring 52. At this time, the tension of the second spring spring 52 on the synthetic rubber clamping plate 51 will decrease. Thus, the clamping force of the motor casting housing body 1 can be adjusted according to the model of the motor casting housing body 1.

10. The method of using a deformation-resistant machining fixture for a track traction motor casting housing according to any one of claims 1-9, characterized in that: S1: To achieve rapid clamping of the motor casting housing body (1) and to prevent damage to the motor casting housing body (1) during clamping, the first spring spring (34) provides elastic torque to maintain the rotation of the shaft roller (33). The shaft roller (33) is rotatably connected to the inner side of the shaft groove (32) opened in the fixed arm frame (31). The shaft roller (33) drives the folded clamping arm (35) and the roller (36) to rotate, so that the outer side of the roller (36) is kept in contact with the lower end of the notched cone (24), while the upper part of the folded clamping arm (35) is kept expanding outward, and the upper folded clamping arms (35) are separated from each other. The electric motor is started. The telescopic rod (23) drives the notched cone (24) to move downwards. The notched cone (24) moves inside the movable groove (22). The notched cone (24) squeezes the roller (36). When the notched cone (24) moves, it squeezes the roller (36). The roller (36) rotates inside the folded clamping arm (35). The roller (36) drives the folded clamping arm (35) to rotate around the shaft roller (33). At this time, the folded clamping arm (35) drives the fixed spring plate (37) at the top to move closer to the motor casting housing body (1). The fixed spring plate (37) drives the stabilizing shell assembly (4) and the clamping adjustment assembly (5) to move as a whole, so that the three synthetic rubber clamping plates (5) 1) At the same time, the outer side of the motor casting housing body (1) is clamped. When the synthetic rubber clamp (51) is attached to the motor casting housing body (1), the inner groove spring shell (44) and the adjusting convex shell (45) of the synthetic rubber clamp (51) rotate at a certain angle. The inner groove spring shell (44) drives the connecting plate (43) to rotate. The connecting plate (43) drives the fixed shaft ear seat (41) and the shaft rod (42) to rotate. The shaft rod (42) rotates and connects to the inner side of the inner hole ear seat (39). The connecting plate (43) squeezes or stretches the four linear springs (38). This structure allows the synthetic rubber clamp (51) to have a larger area with the motor casting housing body (1). The outer side is attached to the synthetic rubber clamp (51) to disperse the pressure of the synthetic rubber clamp (51) on the motor casting housing body (1). When clamping the motor casting housing body (1) to prevent damage to the motor casting housing body (1), the synthetic rubber clamp (51) is attached to the outer side of the motor casting housing body (1). At this time, the synthetic rubber clamp (51) pulls the second spring (52) fixed on both sides. The second spring (52) stretches elastically. Under the torsional action of the second spring (52), the synthetic rubber clamp (51) is a nitrile rubber. After it is attached to the motor casting housing body (1), it will deform to a certain extent with the shape of the motor casting housing body (1). S2: To adjust the clamping force of the motor casting housing body (1) to adapt to the clamping effect of motor casting housing body (1) of different materials, rotate the connecting piece (55). The connecting piece (55) drives the ratchet (54) and the vertical rotating column (53) to rotate. The vertical rotating column (53) is rotatably connected to the inner side of the inner groove spring shell (44). When rotating, it winds up the second spring (52), that is, the elastic movement distance of the second spring (52) decreases. At this time, the second spring ( The elastic travel distance of the second spring (52) will change. According to Hooke's Law, when the elastic travel distance of the second spring (52) increases, the elastic tension of the second spring (52) on the synthetic rubber clamp (51) will decrease. When the elastic travel distance of the second spring (52) decreases, the elastic tension of the second spring (52) on the synthetic rubber clamp (51) will increase. This allows control over the clamping force of the synthetic rubber clamp (51) on the motor casting housing body (1). To adapt to different motor casting housing bodies (1) clamping operations, when the ratchet (54) rotates, it will push the one-way toothed slide plate (47) to move. According to the tooth shape of the one-way toothed slide plate (47) and the ratchet (54), when the one-way toothed slide plate (47) meshes with the ratchet (54), the vertical rotating column (53) rotates when winding the second spring (52). Under the action of the elastic force of the spring extension rod (46), the one-way toothed slide plate (47) is kept meshed with the outside of the ratchet (54). It is necessary to adjust the first When the second spring (52) is loosened, and the elastic movement distance of the second spring (52) increases, the operating lever (48) is pulled. The operating lever (48) drives the one-way toothed slide plate (47) to move. When the one-way toothed slide plate (47) is engaged with the ratchet (54), the vertical column (53) rotates inside the inner groove spring shell (44) under the torque of the second spring (52). At this time, the tension of the second spring (52) on the synthetic rubber plate (51) will decrease.
