Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a machining device for an automotive half shaft. Background Art

[0002] The half shaft, also called the drive shaft, is the shaft that connects the differential to the drive wheels. The half shaft is the shaft that transmits torque between the gearbox reducer and the drive wheels. There are universal joints (U / JOINTS) at both the inner and outer ends, which are respectively connected to the reducer gear and the inner ring of the hub bearing through the splines on the universal joints. For the commonly used half shafts in modern automobiles, according to their support types, there are two types: full floating type and semi-floating type. When working, the half shaft that only bears torque and whose two ends do not bear any force and bending moment is called a full floating type half shaft. The outer flange of the half shaft is fastened to the hub with bolts, and the hub is installed on the half shaft sleeve through two bearings that are relatively far apart. Structurally, the inner end of the full floating type half shaft is made with splines, and the outer end is made with a flange, and there are several holes on the flange. Because of its reliable work, it is widely used in commercial vehicles.

[0003] When machining the half shaft, a machining device will be used.

[0031] Move the block 4, the block 4 is respectively threadedly connected to both ends of the outer side of the bidirectional threaded rod 23, and a telescopic rod 41 is provided at the top of the block 4;

[0032] A placement rack 5, the placement rack 5 is fixedly installed at the top of the telescopic rod 41, a moving groove 51 is opened at the top of the placement rack 5, a slider 53 is slidably connected to the inner side surface of the moving groove 51, one end of the placement rack 5 is fixedly installed with a hydraulic rod 52, and the moving end of the hydraulic rod 52 is fixedly installed on one side of the slider 53. A through hole 55 is opened on one side of the slider 53, a pushing block 56 is arranged on the inner side surface of the through hole 55, a limiting plate 58 is fixedly installed on one side of the pushing block 56, and a spring 54 is fixedly installed on one side of the limiting plate 58.

[0033] One end of the bidirectional threaded rod 23 is rotatably connected to one end of the inner side surface of the sliding groove 21, and both sides of the block 4 are attached to both sides of the inner side surface of the sliding groove 21.

[0034] A rubber pad 57 is fixedly installed on the other side of the pushing block 56.

[0035] Both the limiting plate 58 and the spring 54 are arranged on the inner side surface of the slider 53.

[0036] Through the setting of the rubber pad 57, during use, it can play a role in protecting the half shaft, avoiding friction between the pushing block 56 and the half shaft, and causing damage to the half shaft;

[0037] By sliding the block 4 on the inner side surface of the sliding groove 21 and making both sides of the block 4 fit with both sides of the inner side surface of the sliding groove 21, the block 4 can be limited, and the stability of the movement of the block 4 can be increased.

[0038] The working principle of an automobile half shaft processing device provided by the present utility model is as follows:

[0039] When in use, the user places the half shaft on the top of the placement rack 5, and then the user starts the hydraulic rod 52 to extend the hydraulic rod 52 to drive the slider 53 to move, so that the slider 53 drives the pushing block 56 to move towards one side of the half shaft, thereby pushing the half shaft to the inner side of the placement rack 5 until one side of the half shaft abuts against one side of the inner side of the placement rack 5 until the end of the pushing block 56 away from the half shaft drives the limiting plate 58 to squeeze the spring 54, and then elasticity is generated to play a buffering role. When the half shafts placed on the two placement racks 5 are short in length, the user can start the driving motor 22 to drive the bidirectional threaded rod 23 to be threadedly connected inside the moving block 4, so that the moving block 4 moves towards the middle, and the moving block 4 will drive the telescopic rod 41 to move, thereby driving the placement rack 5 to move.

[0040] Compared with the related art, a kind of automobile half shaft processing device provided by the utility model has the following

[0041] Beneficial effects:

[0042] Through the cooperation of structures such as the placement rack 5, the moving groove 51, the hydraulic rod 52, the slider 53, the spring 54, the through hole 55, the pushing block 56 and the rubber pad 57, when in use, the hydraulic rod 52 can push the slider 53, so as to automatically limit and fix the half shaft, without the need for the user to manually operate, thereby reducing the operation steps and facilitating the user to use.

[0043] Second Embodiment

[0048] The working principle of a half shaft processing device for automobiles provided by the utility model is as follows:

[0049] When in use, the rotation of the bidirectional threaded rod 23 drives the two moving blocks 4 to move. At this time, the moving blocks 4 drive the fixed blocks 6 to slide on the outer side of the baffle 62. In this way, when the half shaft is processed subsequently, the debris can fall onto the baffle 62 and then be guided to the top of the mounting seat 2, preventing the debris from falling onto the bidirectional threaded rod 23.
