Embodiment 1

[0016] Example 1: see figure 1 , figure 2 , an automatic cycle tool rest device for ordinary lathe thread processing, including a tool rest 1 fixedly connected to the upper body 2 of the tool rest, and connected to an insert 3 provided between the upper body 2 of the tool rest and the guide rail of the saddle 7 The small shaft 4 and the output shaft of the locking oil cylinder 6 are connected with the small shaft 4; on the upper body 2 of the knife rest, the support 10 is fixedly connected by the screw 9, and the support 10 is fixedly connected with the oil cylinder 11 by the locking screw 12.

Embodiment 2

[0017] Example 2: see figure 1 , figure 2 , a thread processing method for ordinary lathes with an automatic cycle tool holder device for processing threads. Its main feature is that the turning tool 8 is first installed on the tool holder 1, and the left end positioning block 13 and the right end positioning block installed on the bed are adjusted according to the length of the thread. block 14 distance, the bed saddle 7 moves longitudinally along the bed during thread turning, when the control switch 15 touches the right end positioning block 14, the locking cylinder 6 releases the inlay 3 through the small shaft 4, and the oil cylinder 11 passes the bracket 10 screws 9 Quickly return the tool holder upper body 2 and the tool holder to achieve the purpose of rapid tool retraction. When executing the next thread processing cycle, wait for the bed saddle 7 to control the switch 15 to move in reverse along the bed to the other left end positioning block At 13 o'clock, the oi...

Abstract

The invention relates to a thread machining technology of an engine lathe, and particularly achieves the effect of machining threads of technology-free idle tools through the engine lathe. The automatic tool retracting function is achieved under the condition that the rotating direction of a machine tool spindle is not changed. An automatic circulation tool rest device for thread machining of the engine lathe is mainly characterized by comprising a tool rest fixedly connected to a tool rest upper body, a small shaft is connected to an inlaid strip arranged between the tool rest upper body and a saddle guide rail, an output shaft of a locking oil cylinder is connected with the small shaft, the tool rest upper body is fixedly connected with a support through screws, and the support is fixedly connected with the oil cylinder through locking screws. The physical labor intensity of a worker can be relieved, the auxiliary time can be shortened, one worker can watch multiple machine tools, and therefore the productivity is high.

Description

technical field [0001] The invention relates to a common lathe thread processing technology, in particular to solve the problem of the common lathe processing the thread without a process empty tool, and can realize functions such as automatic tool retraction under the condition that the rotation direction of the main shaft of the machine tool remains unchanged. Background technique [0002] At present, the common lathe used for thread processing in the industry, the feed system is composed of the main transmission system, the tool box, the lead screw, the slide box, the tool holder and so on. Because the thread processing needs to be processed in a cycle, when the first feeding is finished and the tool needs to be withdrawn, the spindle should be stopped first, and then started in the opposite direction. Due to the long braking time and the influence of the manufacturing accuracy of the transmission system parts, when the spindle When it stops and then reverses and starts, ...
