Detailed Description

The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.

As shown in fig. 1 to 4, the rotary station device of the screw sleeve machining combined machine tool provided by the invention comprises a feeding and discharging station 1, a vertical primary and secondary spindle cutting unit 2, a vertical turning unit 3, a primary and secondary turning unit 4, a rotary table 5, a base 6, a three-jaw chuck 7 and a driving motor 8, and is mainly divided into three major parts, wherein the first part is the base 6, the second part is the rotary table 5 mounted on the base 6, and the third part is two, three and four stations on the rotary table. The rotary table 5 is connected to the base 6 through a turntable bearing so that the rotary table 5 can rotate around the axis. Four processing stations are arranged on the rotary worktable 5 and respectively comprise a feeding and discharging station 1, a vertical primary and secondary main shaft cutting unit 2, a vertical turning unit 3 and a primary and secondary turning unit 4. A three-jaw chuck 7 is arranged above each station and used for clamping a workpiece; below the station is a drive motor 8 for driving the workpiece in rotation.

More specifically, the base 6 of the present invention has a receiving cavity in the middle thereof, a support shaft is disposed in the receiving cavity, and the rotary table is mounted on the support shaft through a turntable bearing and is rotatable with respect to the support shaft.

The invention has four stations, and each station can independently execute different steps of thread insert processing. The vertical type primary and secondary main shaft cutting unit 2 mainly performs first step rough turning of left and right end faces of the thread insert, and after the first step machining is completed, the rotary workbench 5 rotates 90 degrees anticlockwise and rotates to the vertical type turning unit 3. The second step of performing the thread insert machining on the vertical turning unit 3 finishes the left and right end faces. And after finishing turning, rotating the workbench 5 by 90 degrees anticlockwise again, rotating the workbench to the primary turning unit 4, and finishing turning the phi 38 inner hole in a third step. Finish turning hole accomplishes the back, and rotatory workstation counter-clockwise turning 90 rotates the material piece and goes up unloading station 1, carries out last process step: and detecting the threads and feeding.

According to the invention, the upright post is arranged above the station, the tool magazine and the chuck are respectively fixed on the upright post, the chuck below the upright post is positioned on the rotary workbench, and the workpiece rotates to the next station along with the chuck to perform the next processing of the part. In addition, the machining of the station parts is synchronous, namely the machining of a plurality of stations is carried out simultaneously, so that the machining efficiency is greatly increased.

Generally, four working steps are needed for machining the screw sleeve, and in the traditional working mode, an operator needs to frequently disassemble parts and set tools to complete the four working steps, so that the production efficiency is low. Aiming at the problems, the special machine concentrates four working steps on one machine tool, greatly increases the automation degree, and solves the problems of slow manual efficiency, inconsistent processing quality and high randomness of the traditional manual operation.
