In this embodiment, the second elastic member 26 is a spring.

The implementation principle of the turntable in the embodiment of the application is as follows:

when a workpiece is machined, the first driving piece 41 can be controlled to drive the rotary table 4 to rotate, the rotary table 4 drives the main shaft 5 to rotate, and then the cutter on the main shaft 5 is driven to move, so that the workpiece is machined at different angles, the freedom degree of the machined workpiece is improved, more requirements for machining the workpiece can be met, and the applicability and the practicability of the machine tool are improved.

Still can be according to the size of work piece, the three 3 drive lead screws of control driving piece 2 rotates, drives slide 12 and reciprocates, and then drives the cutter on the main shaft 5 and takes place to remove for the cutter with wait to process the work piece and aim at, so that the cutter processes the work piece, further improved the suitability of revolving stage.

The slide 12 moves the process and drives the linkage block 202 to move back and forth, so that the lead screw 2 and the stretching part 122 are lubricated by automatic oil injection, the abrasion between the lead screw 2 and the slide 12 is reduced, the rotary table is more durable, the looseness between the lead screw 2 and the slide 12 is reduced, and the integral stability of the rotary table is improved.

Excessive fluid drops to the flourishing groove 81 on the oil tank 8 along the lead screw 2 and collects, and follow-up oil delivery piece 9 continues to deliver the fluid of collecting in the oil tank 8 to the lead screw 2 department and lubricate, has reduced the waste of fluid to the impurity that has carried in the fluid has been reduced to the driven influence between slide 12 and the lead screw 2.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
