Problems solved by technology

At present, most machine tools use double workbenches, and the exchange of worktables mainly adopts the method of holding up the workbench with a large exchange fork and then rotating the workbench, and the workbench is usually transported by pushing and pulling the oil cylinder. For a long time, the connecting bearing has to rotate and be affected by the lifting and lowering, the reliability is not good, and a large turning radius is required, which affects the overall layout and appearance of the machine tool and greatly reduces the overall performance of the machine tool

Embodiment Construction

[0014] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0015] As shown in the figure, a small-radius exchange table for a machine tool includes a slewing mechanism, a lifting mechanism and a lifting detection mechanism arranged on the exchange table base 4. A support sleeve 41 is installed on the exchange table base 4. The upper and lower ends of the support sleeve 41 A one-way thrust ball bearing 42 and a needle roller bearing 43 are installed on the outer side.

[0016] The rotary mechanism includes a rotary base 11, a rotary shaft 12, a rotary sleeve 13, a gear 14, a rack 15, and two rotary oil cylinders 16 symmetrically arranged on one side of the rotary shaft 12. The two rotary oil cylinders 16 are connected by the rack 15. The rotating sleeve 13 is sleeved on the outer side of the supporting sleeve 41 and leans on the one-way thrust ball bearing 42, the gear 14 is sleeved on the bottom of t...

Abstract

The invention discloses a minor radius exchange platform for a machine tool. The minor radius exchange platform for the machine tool is driven by a rotation oil cylinder, drives a rotary sleeve, a guiding sleeve, a rotary base, a rotary shaft and a piston to rotate in a gear rack transmission mode and then drives a clamping mechanism and the workbench to rotate to achieve a rotation function of the exchange platform. Lifting of a gland, a cylinder body, the guiding sleeve and the rotary base is achieved through control of pressure oil inside a first oil chamber and a second oil chamber which are arranged above and below the piston, a lifting function of the exchange platform is achieved, only the gland, the cylinder body, the guiding sleeve and the rotary base perform the lifting action, other parts inside the exchange platform are not involved, and separation of a rotation structure and the lifting structure can be achieved. A workbench can stably rotate within minor radius along with the exchange platform through a clamping mechanism clamping workbench which is connected to the rotary base. The minor radius exchange platform for the machine tool has the advantages of being simple and compact in structure, greatly improving the structure stability and accuracy, shrinking the rotation radius of the wokbench and improving the exchange speed, the reliability and the action efficiency.

Description

technical field [0001] The invention relates to an exchange station in the composition of a machine tool, in particular to a small-radius exchange table of a machine tool. Background technique [0002] With the rapid development of the manufacturing industry and the continuous updating of technology, higher requirements have been placed on the mechanical processing equipment. At present, most machine tools use double worktables. The worktable exchange mainly uses a larger exchange fork to hold up the worktable and then rotate it for exchange, and the worktable is often transported by pushing and pulling the oil cylinder. This structure and action are more complicated and the exchange For a long time, the connecting bearing must rotate and be affected by the lifting and falling, the reliability is not good, and a large turning radius is required, which affects the overall layout and appearance of the machine tool, and greatly reduces the overall performance of the machine too...
