Embodiment 1

[0027] like figure 1 , figure 2 As shown, a machine tool includes a frame 1, a turntable, a fixed seat 2, a main shaft 3, a sub-disc 4 and a support sleeve 5. Located between the two side plate parts 11, the fixing seat 2 includes a cylindrical seat body 21 and an annular bearing cover 22, the seat body 21 is horizontally fixed on one of the side plate parts 11, and one end of the seat body 21 extends into both sides Between the plate parts 11, the main shaft 3 is installed in the seat body 21, and a bearing 24 is installed between the two, so that the main shaft 3 can rotate, and the bearing cover 22 is fixed on the end of the seat body 21 protruding in, and the bearing 24 is positioned. , the auxiliary disk 4 is vertically arranged, one side of the auxiliary disk 4 is fixed to the end of the main shaft 3, and the other side is connected to the other side side plate 11 through the support sleeve 5. At this time, the end surface of the bearing cover 22 is in contact with the...

Embodiment 2

[0032] This machine tool is basically the same as Embodiment 1, the difference is that the sealing ring 7 and the dustproof ring 8 are all arranged on the bearing cover 22, that is, the first step 411 and the second step 412 are all set at the end of the bearing cover 22, and also have Better sealing effect.

Abstract

The invention provides a machine tool, and belongs to the technical field of mechanical equipment. The problem to be solved by the machine tool is that the sealing performance and the service life ofan existing machine tool are difficult to consider at the same time. The machine tool comprises a rack, a fixing base fixed to the rack, a main shaft arranged in the fixing base in a penetrating modeand an auxiliary disc fixed to one end of the main shaft, a sealing protruding part is arranged on the side face of the auxiliary disc in the circumferential direction, the end of the fixing base is inserted into the inner side of the sealing protruding part, and an air storage cavity is formed between the end of the fixing base and the side face of the auxiliary disc; and a sealing ring and a dustproof ring are arranged between the sealing protruding part and the fixing base, a limiting part is arranged between the sealing protruding part and the fixing base, when the air storage cavity is inan uninflated state, sealing between the sealing protruding part and the fixing base by the dustproof ring is tighter than sealing between the sealing protruding part and the fixing base by the sealing ring, and a sealing lip part is arranged on the sealing ring in the circumferential direction. The service life of the machine tool can be prolonged while the sealing effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment and relates to a machine tool. Background technique [0002] The machine tool can clamp the workpiece, and then perform tapping, reaming, grinding and other processing procedures. In order to integrate various functions, the current waterwheel machine tool has multiple power heads at the same time, and each power head can complete different processes. The machine tool The middle part is equipped with a sub-disc for clamping multiple workpieces. Multiple power heads can perform different processing procedures on different workpieces at the same time, and then perform transposition through the rotation of the sub-disk. Clamp and position multiple workpieces, and each fixture has an oil cylinder that provides clamping force. Since the auxiliary disc can rotate, the oil cylinders distributed on the auxiliary disc in the circumferential direction need an oil separator to separate the exter...
