Description

Technical Field

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

[0002] Shaft rod parts are widely used in automobiles, aviation, precision instruments and various mechanical equipment, and they are crucial for ensuring the precise operation and long-term stability of the equipment. During the manufacturing process of shaft rods, especially after heat treatment, machining or long-term storage, they often show varying degrees of bending deformation, which directly affects their assembly accuracy and service performance. Therefore, it is necessary to straighten the shaft rods.

Through the above technical solution, the problem that a large amount of time is required for straightening the shaft rod raw material in the related art, increasing the production cost, is solved.

[0004] In the above technology, the shaft rod is fixed by the clamping and supporting assembly, and then the bending position is detected and marked by the detecting member. The clamping and supporting assembly lifts the shaft rod, and finally straightening is carried out. During the whole straightening process, the shaft rod remains stationary, making it difficult for the detecting member to comprehensively capture the three-dimensional bending situation of the shaft rod. Moreover, during the straightening process, the fixing position of the shaft rod limits the angle and direction of the straightening force, and it is impossible to apply the straightening force to all the bent parts of the shaft rod simultaneously or optimally. During the straightening process, it is necessary to manually adjust the shaft rod, resulting in a reduction in straightening efficiency. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0022] Combined Figure 1 and Figures 3 - 4 , a straightening device for a shaft rod, comprising a support table 1, a straightening table 2 movably arranged at the top end of the support table 1, a detecting member movably arranged at the top end of the support table 1, a first support seat 6 fixedly connected to the top end of the support table 1, a second support seat 61 fixedly connected to the top end of the first support seat 6, a hydraulic cylinder 7 fixedly connected to the bottom end of the second support seat 61, a hydraulic rod 71 fixedly connected to the bottom end of the hydraulic cylinder 7, and a straightening block 8 fixedly connected to the telescopic end of the hydraulic rod 71. The hydraulic rod 71 penetrates through the first support seat 6. A sliding opening 22 is formed on the upper surface of the straightening table 2, and a groove 23 is formed on the lower surface of the straightening table 2. A clamping assembly 3 for clamping the shaft rod is arranged above the groove 23, and the groove 23 communicates with the sliding opening 22. The following further describes the present invention in conjunction with the embodiments. Embodiment

[0023] Please refer to Figures 2 - 6 , the clamping assembly 3 includes a threaded rod 31 movably arranged inside the groove 23, a first motor 32 fixedly connected to one end of the straightening table 2, a fixing plate 33 threadedly connected to the outer surface of the threaded rod 31, a support plate 34 fixedly connected to the top end of the fixing plate 33, a mounting plate 35 fixedly connected to the top end of the support plate 34, a second motor 36 fixedly connected to one side of the mounting plate 35, a connecting rod fixedly connected to the output end of the second motor 36, and a mounting cylinder 37 fixedly connected to one end of the connecting rod. The connecting rod rotatably penetrates through the mounting plate 35. The support plate 34 is slidably connected to the sliding opening 22. One end of the threaded rod 31 is rotatably connected to the side wall of the groove 23, and the other end of the threaded rod 31 rotatably penetrates through the side wall of the groove 23 and is fixedly connected to the first motor 32. The mounting cylinder 37 is used for fixing the shaft rod. By driving the threaded rod 31 to rotate through the first motor 32, the rotation of the threaded rod 31 drives the fixing plate 33 and the support plate 34 and the mounting plate 35 thereon to accurately move along the direction of the threaded rod 31, thereby driving the mounting cylinder 37 to move, facilitating the clamping of shaft rods of different sizes. By driving the connecting rod and the mounting cylinder 37 to rotate through the second motor 36, the shaft rod is driven to rotate, facilitating the shaft rod to pass through the measurement of the detecting member in sequence at each part, more comprehensively detecting the bending position and direction of the shaft rod, and accurately identifying the bending degree of each cross-section.

[0024] A supporting plate 4 is movably arranged at the top end of the straightening table 2. A first slider 41 is fixedly connected to the bottom end of the supporting plate 4. A first sliding groove 21 is formed on the upper surface of the straightening table 2. The first slider 41 is slidably connected to the first sliding groove 21. Through the sliding connection between the first slider 41 and the first sliding groove 21, it is convenient for the supporting plate 4 to adjust the front and rear positions at the top end of the straightening table 2 according to the length of the shaft rod or the straightening requirements, so as to adapt to shaft rods of different sizes.

[0025] A sponge pad 42 is fixedly connected to the top end of the supporting plate 4. As a soft material, the sponge pad 42 is convenient for effectively buffering the direct contact between the shaft rod and the hard supporting plate 4, preventing scratches or damages to the surface of the shaft rod during the straightening process. Moreover, the sponge pad 42 is convenient for adapting to slight changes in the shape of the shaft rod, and evenly disperses the pressure exerted on the shaft rod through deformation, avoiding excessive local stress during straightening.

[0026] A spring 371 is fixedly connected to the inner wall of the installation cylinder 37. One end of the spring 371 is fixedly connected to a clamping plate 3711. When the shaft rod is placed and contacts the clamping plate 3711, the spring 371 will be compressed, which is convenient for automatically adjusting the clamping force according to the diameter of the shaft rod, ensuring that the shaft rod is firmly fixed and applicable to shaft rods within different diameter ranges.

[0027] A second sliding groove 231 is formed on the side wall of the groove 23. A second slider 331 is formed on one side of the fixing plate 33. The second slider 331 is slidably connected to the second sliding groove 231. When the fixing plate 33 and the supporting plate 34 and the mounting plate 35 thereon move precisely along the thread direction, the second slider 331 slides along the second sliding groove 231, playing a guiding role.

[0028] A limiting plate 5 is fixedly connected to the top end of the support table 1. The inner surface of the limiting plate 5 is in contact with the outer surface of the straightening table 2. As a position limiting element, the limiting plate 5 prevents the straightening table 2 from shifting during the movement process.

[0029] In use, the first motor 32 drives the threaded rod 31 to rotate. The rotation of the threaded rod 31 drives the fixed plate 33, the support plate 34 thereon, and the mounting plate 35 to accurately move along the direction of the threaded rod 31, thereby driving the mounting cylinder 37 to move, facilitating the clamping of shaft rods of different sizes. One end of the shaft rod is placed inside the mounting cylinder 37, and the outer surface of the shaft rod contacts the clamping plate 3711. At this time, the spring 371 is compressed, and the reaction force generated by the spring 371 fixes the outer surface of the shaft rod through the clamping plate 3711, facilitating the fixing of the shaft rod. When using the detection piece for detection, the second motor 36 drives the connecting rod and the mounting cylinder 37 to rotate, thereby driving the shaft rod to rotate, facilitating each part of the shaft rod to pass through the measurement of the detection piece in sequence, more comprehensively detecting the bending position and direction of the shaft rod, and enabling the bending degree of each cross-section to be accurately identified. The detection piece is a level. By adjusting the height of the level, the horizontal line is located at the edge of the shaft rod. After observation, the bending position is marked. After the detection is completed, the hydraulic rod 71 drives the straightening block 8 to move up and down to apply the most suitable straightening force to each bending section of the shaft rod for straightening operation. At this time, the sponge pad 42, as a soft material, facilitates effectively buffering the direct contact between the shaft rod and the hard support plate 4, preventing scratches or damage to the surface of the shaft rod during the straightening process, and the sponge pad 42 is convenient for adapting to the slight changes in the shape of the shaft rod, evenly dispersing the pressure exerted on the shaft rod through deformation, and avoiding excessive local stress during straightening.
