Pneumatic automatic propelling device for lathe machining

Abstract

The invention relates to the technical field of machining, and particularly discloses a pneumatic automatic propelling device for lathe machining. The device comprises a base, a middle positioning mechanism arranged in the middle of the upper end of the base, a driving guide mechanism arranged on the left side of the base and a driven guide mechanism arranged on the right side of the base, whereinthe middle positioning mechanism is composed of a middle sliding base, a sliding assembly, a lifting air cylinder and a positioning plate, the driving guide mechanism is composed of a lug base, a propelling assembly and a driving assembly, and the driven guide mechanism is composed of a lug base, a propelling assembly and a driven assembly. When the device is used for turning multiple large shaftworkpieces, the multiple workpieces can be placed in positioning guide grooves in the upper end of the positioning plate at a time, then the two ends of each workpiece are positioned and fixed through controlling the sliding assembly, the lifting air cylinder and the propelling assembly, and the machining efficiency is improved; and according to the device, the quick replacement of the workpieceto be machined at the machining position can be completed through controlling the lifting cylinder, the propelling assembly and the sliding assembly, and the production process is not delayed in the whole process.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a pneumatic automatic propulsion device for lathe processing. Background technique [0002] Turning is a common processing method in mechanical processing. The outer circle processing of shafts is the most common processing method in turning processing. When large shafts are processed on a lathe, the shaft needs to be lifted first, and then left and right on the lathe. Align the head and tail, use the top cone to tighten, and then process. This processing method is relatively simple, but it still has the following shortcomings in actual use: [0003] 1. When processing multiple large shafts, it is necessary to hoist and position the shafts to be processed one by one. The entire operation process takes a long time, which increases the cost of man-hours; [0004] 2. When hoisting is used for positioning, it is necessary to align the two ends of the shaft with the top...

AI Technical Summary

Problems solved by technology

[0003] 1. When processing multiple large shafts, it is necessary to hoist and position the shafts to be processed one by one. The entire operation process takes a long time, which increases the cost of man-hours;

[0004] 2. When hoisting is used for positioning, it is necessary to align the two ends of the shaft with the top cones at the head and tail positions of the lathe respectively. The operation process requires certain technical requirements and requires a high level of operating skills for the operator, so there is a problem for the operator relatively restrictive;

[0005] 3. During the positioning of the axis before machining and the process of returning the workpiece after machining, most of its operations are carried out at the processing position. Therefore, during this period, the processing position cannot be processed, resulting in a certain waste of resources
