Description

Technical Field

[0001] The utility model relates to the technical field of axles of excavators and loaders, in particular to a boring device for axles of excavators and loaders. Background Art

[0002] The axle of an excavator loader is generally composed of a transmission shaft, a reducer, a differential, a final reducer, gears, rims, brakes and other parts. It refers to the drive and suspension system used for the excavator loader. When processing and repairing it, a boring device is often required to perform boring operations to ensure the precise installation of the axle components and the normal operation of the overall structure of the axle.

[0003] At present, in normal operation, the boring device generally places the axle of the excavator loader on the surface of the load-bearing plate so that the limit rod can position it. However, since the limit rod only limits one side of the axle of the excavator loader and does not restrict both ends, the length of the axle may cause looseness or slight movement. These slight movements gradually accumulate during the entire boring process, resulting in inaccurate boring positions. Furthermore, since the position of the boring bar is generally fixed, the boring bar in a fixed position can only be processed within a fixed range. When deep boring is performed on the axle of the excavator loader, multiple adjustments and movements are required to complete the entire deep boring process, which reduces the processing efficiency.

[0004] In summary, the current boring device still has the following defects during use:

[0005] (1) Positioning only one side of the backhoe loader axle will lead to the accumulation of processing errors, resulting in inaccurate boring positions;

[0006] (2) When using a fixed-position boring bar to perform deep boring on the axle of an excavator loader, the operation is cumbersome and will result in reduced processing efficiency. Utility Model Content

[0034] The clamping assembly 4 includes support plates 41 located on both sides of the supporting plate 1, and motors 42 are installed on the top of the two support plates 41. The output end of the motor 42 is fixedly connected to a bidirectional screw 43, and both ends of the bidirectional screw 43 are rotatably installed on the support plate 41. The bidirectional screw 43 is threadedly connected to a relatively set slider 44. The output end of the motor 42 extends to the inner side of the support plate 41 and is fixedly connected to the bidirectional screw 43. The motor B62 extends to the other end of the vertical plate 6 and is connected to the boring rod 61. The motor B62 is used to drive the boring rod 61.

[0035] One side of the two sliders 44 is fixedly connected with a connecting block 45, and a sliding rod 46 is slidably inserted between the two connecting blocks 45. Both ends of the sliding rod 46 are fixedly installed on the top of the support plate 41. The top of the slider 44 is fixedly connected with a positioning assembly 47.

[0039] During use, the excavator loader axle is placed on the surface of the bearing plate 1 so that one end of it is in contact with the limit rod 31, and then the motor 42 is started to drive the bidirectional screw 43 to rotate, so that the two sets of sliders 44 drive the positioning components 47 to approach each other. When the positioning components 47 connect the two ends of the excavator loader axle, the electric push rod 475 can be started to push the movable arc plate 474 to slide along the inside of the guide groove 477 through the guide block 476, so that the movable arc plate 474 moves toward the fixed arc plate 473 until the movable arc plate 474 positions the two ends of the excavator loader axle to complete the operation.

The output end of the motor A53 extends to the inner side of the baffle 57 and is fixedly connected to the transmission shaft 54. The motor A53 is used to drive the transmission shaft 54, thereby driving the vertical plate 6 to move.

[0042] A mounting plate 55 is slidably mounted on the top of the base plate 51, a slide groove 56 is provided at the bottom of the mounting plate 55, the slide groove 56 is slidably connected to the slide rail 52, the top of the mounting plate 55 is fixedly connected to the vertical plate 6, and the bottom of the mounting plate 55 is threadedly connected to the transmission shaft 54. When the transmission shaft 54 ​​rotates, the mounting plate 55 can be driven to move, thereby achieving the purpose of adjusting the position of the boring bar 61.

[0043] During use, the motor A53 can be started to drive the transmission shaft 54 ​​to rotate, and drive the mounting plate 55 and the vertical plate 6 to move. During this process, the mounting plate 55 can slide along the surface of the slide rail 52 through the slide groove 56, thereby driving the boring rod 61 to adjust its position. This method is simple to operate, and further solves the problem that the boring rod 61 in a fixed position is cumbersome to operate when performing deep boring on the axle of an excavator loader, and it will lead to reduced processing efficiency.
