Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0021] Such as Figure 1 to Figure 4 One of them shows: a kind of lifting composite exchange bracket, which includes a lifting frame 1, a lifting hook groove block 2, a workbench 3; a lifting shaft 4; the supporting frame 1 is S-shaped in shape, and U-shaped lifting card 11, arc-shaped lifting hook card 12, and installation hole 13 are provided; the two lifting hook groove blocks 2 are symmetrically arranged on the sides of...

Abstract

The invention discloses a supporting and shouldering composite exchange bracket. The supporting and shouldering composite exchange bracket comprises a supporting and shouldering rack, supporting and shouldering hook groove blocks, working tables and a lifting rotating shaft, wherein the supporting and shouldering rack is S-shaped and is provided with a U-shaped supporting and raising card, an arc-shaped shouldering and hooking card and a mounting hole; the two supporting and shouldering hook groove blocks are symmetrically arranged on side surfaces of the two working tables and are connected with the working tables in a fastened manner; an arc-shaped hook groove cavity is formed in each supporting and shouldering hook groove block; a projected step is arranged at the bottom of each working table; the lifting rotating shaft penetrates through the mounting hole; and the lifting rotating shaft and the supporting and shouldering rack are fixed. The supporting and shouldering composite exchange bracket has the advantages of stability, reliability and high carrying ability like a double-fork bracket and has the advantages of capability of being used for a machine with cross guide tracks like a hooking and shouldering bracket; and the following shortcomings of the two existing rotary brackets are overcome: the double-fork bracket cannot be used for a machine tool of which the movement directions of a working table are two axial directions, and the hooking and shouldering bracket is not high in carrying ability and cannot be used for large and medium-sized machine tools.

Description

technical field [0001] The invention relates to a worktable exchanging bracket of a machine tool, in particular to a pick-and-lift composite exchanging bracket. Background technique [0002] At present, the mainstream way of exchanging machine tool worktables is the rotary type, and the brackets used in this way are usually the following two types: double-fork brackets and hook-type hangers. [0003] Double-fork bracket: The most common type of exchange bracket at present, there are two U-shaped brackets located back to back at both ends of the bracket in the length direction of the bracket, and one of the U-shaped brackets is located within the travel range of the worktable. When it needs to be exchanged, the workbench reaches the designated position in the U-shaped fork, the lifting mechanism inside the exchange platform drives the bracket to lift the two workbenches at the same time, and the rotation mechanism drives the bracket to rotate 180° to change the position of th...
