Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, and in particular to a special processing machine tool for a hydraulic cylinder. Background Art

[0002] In the production of long shaft parts, due to the particularity of their processing, rotary processing is generally adopted, and one end of the long shaft is fixed, and the other end is suspended for processing. This causes the long shaft to shake slightly up and down or forward and backward during the processing, and because of the processing reasons, the tool on the turret will vibrate during processing, resulting in low precision and poor roughness of the processed parts; at the same time, processing long shaft parts requires the use of multiple different machines for different processes, such as: first rough turning the long shaft to make its surface neat, confirm the center hole, etc., and then clamp it to the fine turning for subsequent processing procedures. Since long shaft parts have high requirements for precision, small shaking or bending or multiple clamping will affect the precision of the long shaft, reducing the qualified rate of the long shaft production; at the same time, the existing shaft processing equipment is difficult to process both ends of the workpiece at the same time during processing, and it is difficult to effectively fix the long shaft, which is easy to produce synchronous vibration with the long shaft, affecting the processing quality and the use effect is not good.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a long-axis turning machine tool [CN201921334730.X], which includes a bed, a spindle for driving the rotation of a workpiece is arranged on the bed, a first clamping device and a second clamping device for clamping the workpiece are arranged on the bed on one side of the spindle, a first turret and a second turret are arranged on the bed and distributed on the upper and lower sides of the workpiece, and during the rotation of the spindle workpiece, the first clamping device, the second clamping device, the first turret and the second turret cooperate with each other to process the workpiece, and a rotating tailstock for fixing multiple tools and the top is movably arranged on the bed, and the top on the rotating tailstock is movably abutted against the center hole of the workpiece.

[0004] The above scheme has solved to a certain extent the problem in the prior art that the tool is prone to tool vibration and low machining accuracy when machining long-axis workpieces. However, the scheme still has many shortcomings, such as: it is difficult to process both ends of the workpiece at the same time, the machining efficiency is low, and the long axis cannot be effectively fixed, and it is easy to resonate with the long axis, affecting the machining quality and the use effect is poor. Summary of the invention
