Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

A double-spindle gang tool lathe is shown in figure 1 and comprises a main machine base 1, wherein a secondary machine box 2 and a cylinder 4 are arranged on the main machine base 1;

wherein, cylinder 4 is equipped with two sets ofly, and two sets of cylinder symmetric distribution connect moving platform 6 jointly on the top, and moving platform 6 level sets up, can realize reciprocating under the drive of cylinder 4. A guide rail 7 is installed on the front side of the moving platform 6, the guide rail 7 is provided with a matched sliding block, the sliding block is fixedly connected with a row of cutter plates 9, and the row of cutter plates 9 move left and right under the matching of the sliding block and the guide rail 7. In order to improve the accuracy of the movement of the sliding block, the sliding block is connected with a lead screw 8, and the lead screw 8 is driven by a lead screw motor 13.

As shown in fig. 1, the longitudinal spindles 10 are mounted on the row cutter plate 9, and two sets of spindles 10 are provided, so that a double-spindle structure is designed to realize synchronous operation of two sets of turning tools and increase the working efficiency of turning. And a driving seat 12 is arranged below each group of main shafts, a turning tool 14 is arranged on the driving seat 12, and the turning tool 14 rotates rapidly to realize turning treatment. A first driving motor 11 is installed in the main shaft 10, the first driving motor 11 drives a driving seat 12 to rotate, and the driving seat 12 is installed at the lower end of the main shaft 10 through a bearing, so that the first driving motor 11 is used for driving the turning tool to rotate.

A driving motor in the two main shafts is controlled by a single chip microcomputer respectively so as to realize independent control of the work of the turning tool. The corresponding design has the work piece swivel mount 3 that can drive the work piece to be turned to rotate, the work piece places the bayonet 15 around the work piece swivel mount 3, the work piece places the bayonet 15 and provides the mounting site for work piece; in order to match with two turning tools on the same row of cutting plates, every two workpiece placing bayonets 15 form a group, the same group of workpiece placing bayonets are positioned on the same side wall of the workpiece rotating seat 3, and the turning tools 14 and the corresponding workpiece placing bayonets are matched for working.

For the workpiece rotating seat 3, the implementation structure of the rotation specifically comprises: firstly, the workpiece rotating seat 3 is positioned at the front side of the secondary case 2, so that the workpiece rotating seat 3 and the turning tool 14 are flush on a longitudinal plane; secondly, as shown in fig. 2, a shaft sleeve 5 is fixedly embedded in the central position of the workpiece rotating seat 3, the shaft sleeve 5 is connected with a connecting shaft 16, a driven gear 17 is mounted on the connecting shaft 16, the driven gear 17 is engaged with a driving gear 18, the driving gear 18 is driven by a second driving motor 19, and the second driving motor 19 is mounted in the secondary case 2; thus, the rotation function of the workpiece rotary table 3 is realized by the cooperation of the driving gear 18 and the driven gear 17.
