As the power source of agricultural machinery products, tractors have a large market demand. Tractors are self-propelled power machines used to pull and drive operating machinery to complete various mobile operations. They can also be used as fixed operating power. They are composed of systems or devices such as engine, transmission, travel, steering, hydraulic suspension, power output, electrical instruments, driving control and traction. The engine power is transmitted to the drive wheel by the transmission system to make the tractor move. In real life, rubber belts are commonly used as the medium for power transmission. According to function and purpose, tractors are divided into agricultural, industrial and special purpose tractors; according to the structural type, they are divided into wheeled, crawler, boat-shaped tractors and self-propelled chassis.

The overall structure is simple, which is convenient for positioning and disassembly of the workpiece, and is easy and reliable to use.

[0004] However, the above structure still has some shortcomings: the above structure fixes the front axle box by multiple positioning pins. Due to the special shape of the tractor front axle box, this method cannot effectively fit and clamp multiple surfaces of the front axle box, and the device cannot fix the front axle boxes of tractors of different sizes, and is not practical.

DETAILED DESCRIPTION

[0025] like Figure 1-3 As shown, a tractor front axle box processing tooling includes a base plate 1, a moving platform 2 is fixedly connected to the top of the base plate 1, two clamping devices 3 for clamping the tractor front axle box are symmetrically arranged above the moving platform 2, a translation component 4 for driving the two clamping devices 3 to move closer to or away from each other is arranged on the moving platform 2, the clamping device 3 includes a supporting plate 31 and a lifting plate 32 arranged opposite to each other, an adjusting component 33 for driving the lifting plate 32 to move closer to or away from the supporting plate 31 is arranged between the supporting plate 31 and the lifting plate 32, and an angle-adjustable clamping component 34 is arranged on the side surface of the supporting plate 31 and the lifting plate 32 that are close to each other.

[0026] The translation assembly 4 includes a movable groove 41 opened on the top of the moving platform 2, and a bidirectional threaded rod 42 is rotatably arranged in the movable groove 41.

[0027] One end of the bidirectional threaded rod 42 is transmission-connected to a driving motor 45 , and the driving motor 45 is fixedly mounted on the moving platform 2 .

[0028] The bidirectional threaded rod 42 is symmetrically threaded with two driving blocks 43 , and the tops of the driving blocks 43 are fixedly connected to the support plate 31 .

[0029] A positioning rod 44 is disposed on one side of the bidirectional threaded rod 42 , and the positioning rod 44 and the bidirectional threaded rod 42 are parallel to each other.

[0030] One end of the positioning rod 44 is fixedly connected to the inner wall of the movable groove 41 , and the other end of the positioning rod 44 passes through the driving block 43 and is fixedly connected to the inner wall of the movable groove 41 .

[0031] Start the drive motor 45, and the drive motor 45 rotates to drive the bidirectional threaded rod 42 to rotate. Under the guidance of the positioning rod 44, the bidirectional threaded rod 42 rotates to drive the two drive blocks 43 to make a linear motion along the axial direction of the bolt rod 342, approaching or moving away from each other, thereby driving the two clamping devices 3 to approach or move away from each other, thereby achieving clamping and fixing of front axle boxes of different sizes.

[0032] The adjusting assembly 33 includes threaded posts 331 fixedly mounted on the four corners of the top of the supporting plate 31 , and the tops of the threaded posts 331 penetrate through the lifting plate 32 and extend to the top thereof.

[0033] A fixing nut 332 is rotatably provided at the top of the lifting plate 32 and at a position corresponding to the threaded column 331 , and the fixing nut 332 is threadedly connected to the threaded column 331 .

[0034] The clamping assembly 34 includes a U-shaped seat 341 fixedly mounted on the support plate 31 or the lifting plate 32 , a bolt rod 342 is inserted into the U-shaped seat 341 , and an adjustment block 345 is threadedly connected to the bolt rod 342 .

[0035] One end of the bolt rod 342 passes through the U-shaped seat 341 and is fixedly connected to the adjusting nut 343 , and the other end of the bolt rod 342 passes through the U-shaped seat 341 and is threadedly connected to the limiting nut 344 .

[0036] A clamping plate 346 is fixedly connected to one side of the adjustment block 345 away from the U-shaped seat 341 , and an elastic friction pad 347 is fixedly connected to the other side of the clamping plate 346 .

[0037] Such a design, through the setting of the elastic friction pad 347, can not only increase the friction between the clamping plate 346 and the front axle box, making the clamping plate 346 more stable and less likely to slide or move; but also can closely fit the front axle boxes of various shapes and sizes, making it easier to install and disassemble.

[0038] When the angle of the clamp 346 needs to be adjusted, loosen the limit nut 344, and then rotate the adjusting nut 343. The rotation of the adjusting nut 343 drives the bolt rod 342 to rotate. The rotation of the bolt rod 342 drives the clamp 346 to rotate through the adjusting block 345, so that the clamp 346 is fitted and fixed to the front axle box surface. Then tighten the locking nut to fix the bolt rod 342, thereby fixing the clamp 346.

[0039] With this design, by adjusting the angle of the clamping plate 346, the clamping plate 346 can better fit the front axle box, which can not only adapt to clamping plates 346 of different shapes, sizes and structures, avoiding the problem of unstable clamping or poor clamping effect caused by the irregular or irregular front axle box, but also reduce the possibility of sliding or movement, improve the stability of clamping, reduce safety hazards during operation, and at the same time reduce the pressure and shear force on the fixed object during the clamping process, which helps to reduce damage or scratches to the front axle box and extend its service life.

[0040] In addition, with this design, the angle of the clamping plate 346 can be quickly adjusted and fit the front axle box, thereby improving work efficiency.

[0041] In specific use, first start the drive motor 45 according to the size of the front axle box. The drive motor 45 rotates to drive the bidirectional threaded rod 42 to rotate. Under the guidance of the positioning rod 44, the bidirectional threaded rod 42 rotates to drive the two drive blocks 43 to make a linear motion along the axial direction of the bolt rod 342, thereby driving the two clamping devices 3 to move closer to or away from each other, so that the two ends of the front axle box are respectively located on the clamping plates 346 on the corresponding support plates 31.

[0042] Then, the fixing nut 332 is rotated, and the rotation of the fixing nut 332 drives the lifting plate 32 to move, and the movement of the lifting plate 32 drives the corresponding clamping plate 346 of the clamping assembly 34 to move downward and close to the front axle box.

[0043] Afterwards, loosen the limit nut 344 and then turn to the adjusting nut 343. The adjusting nut 343 rotates to drive the bolt rod 342 to rotate. The bolt rod 342 rotates through the adjusting block 345 to drive the clamping plate 346 to rotate, so that each clamping plate 346 is fitted and fixed to the corresponding surface of the front axle box. Finally, tighten the limit nut 344 to fix each clamping plate 346, thereby fitting and fixing the front axle box.

[0044] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
