[0002] With the rapid development of the domestic construction machinery industry, the reliability control of construction machinery is becoming more and more strict. In order to improve the reliability of construction machinery, the stability of hydraulic cylinders, which are the core components of construction machinery, is also required to be higher and higher. The stability of the oil cylinder depends on the accuracy of the spline shaft, the main transmission part in the hydraulic cylinder, but the length of the spline shaft is different. When it is fixed, it is prone to dumping, which is difficult to process and easy to cause danger.

The invention discloses a rotary hydraulic oil cylinder spline shaft inner spiral line machining device, and relates to the technical field of spline shaft machining equipment. Supporting rods are fixed to the four corners of the upper surface of the workbench correspondingly, the upper ends of the supporting rods are fixed to the four corners of the lower surface of a fixing ring, a plurality ofclamping mechanisms are arranged on the upper side of the fixing ring and the upper side of the workbench at equal angles, and arc-shaped sliding blocks are fixed to the two sides of the lower surfaceof a bottom plate in each clamping mechanism correspondingly. One side of each arc-shaped sliding block on the outer side is connected with a first circular sliding rail through a positioning bolt, the arc-shaped sliding blocks on the two sides slide on the first circular sliding rail and a second circular sliding rail in an equiangular mode correspondingly, the first circular sliding rail and the second circular sliding rail are fixed to the upper surface of the fixing ring and the upper surface of the workbench correspondingly, a driving mechanism is arranged on the upper side of the fixedring in a suspended mode, and a plurality of supporting columns in the driving mechanism are connected with the lower surface of a fixed plate. The bottom end and the terminal end of a spline shaft are both fixed, the stability of the spline shaft is improved, the phenomenon of toppling is not likely to happen, and then safety is improved.
Description
technical field [0001] The invention relates to the technical field of spline shaft processing equipment, in particular to an inner helix processing device for a spline shaft of a rotary hydraulic oil cylinder. Background technique [0002] With the rapid development of the domestic construction machinery industry, the reliability control of construction machinery is becoming more and more strict. In order to improve the reliability of construction machinery, the stability of hydraulic cylinders, which are the core components of construction machinery, is also required to be higher and higher. The stability of the oil cylinder depends on the accuracy of the spline shaft, the main transmission part in the hydraulic cylinder, but the length of the spline shaft is different. When it is fixed, it is prone to dumping, which is difficult to process and easy to cause danger. Contents of the invention [0003] The object of the present invention is to aim at the defects and defici...
