Problems solved by technology

The outer cover 33 is used to cover the gap between the shaft sleeve body 31 and the mandrel body 32 waterproofly, but it only has the effect of basic waterproofing, and cannot achieve the effect of airtight waterproofing. In addition, this structure is also difficult to assemble and use. Inconvenient, therefore, room for improvement

Embodiment 1

[0044] A spindle waterproof cover, see figure 2, including the main shaft body 10 and the elastic soft cover body 20 .

[0045] see figure 2 and image 3 The main shaft body 10 includes a cylindrical shaft sleeve 11 and a main shaft spindle 12 pivoted in the shaft sleeve 11 . An edge of the inner cylindrical surface of one end of the shaft sleeve 11 is provided with a retaining ring groove 110 . An end portion 120 is provided at one end of the main shaft mandrel 12 close to the snap ring groove 110 of the shaft sleeve 11 .

[0046] see figure 2 and image 3 , the end head 120 is provided with two positioning bumps 121 . The end portion 120 is provided with two locking grooves 122 into which the positioning protrusions 121 respectively extend, and the positioning protrusions 121 and the locking grooves 122 are in an interference fit. Two clamping grooves 122 are disposed on the edge of the outer cylindrical surface of the end portion 120 opposite to each other in the ...

Embodiment 2

[0055] see Figure 7 and Figure 8 , the difference of this embodiment on the basis of Embodiment 1 is that the fixing method between the end portion 120 and the center cover plate 21 does not use the fixing member 212A.

[0056] see Figure 7 and Figure 8 , the side of the two positioning protrusions 121 away from each other is fixed with a locking protrusion 121A, the side of the locking protrusion 121A close to the shaft sleeve 11 and the side of the center cover 21 away from the shaft sleeve 11 abut each other Depend on.

Abstract

Aiming at the problem of poor waterproof effect, the invention provides the following technical scheme: the main shaft waterproof cover comprises a shaft sleeve, a main shaft mandrel pivoted in the shaft sleeve, a central cover plate, a side sealing inclined ring edge arranged on the outer cylindrical surface of the central cover plate, and a rear clamping ring flange arranged on the end surface of the central cover plate; a clamping ring groove is formed in one end of the shaft sleeve, an end head part is arranged at one end, close to the clamping ring groove, of the spindle mandrel, and at least two positioning convex blocks are arranged at the end head part; the end, close to the shaft sleeve, of the side sealing inclined ring edge abuts against the shaft sleeve, the rear clamping ring flange is connected to the clamping ring groove in a sealed and clamped mode, the center cover plate is provided with a sleeving hole allowing the end head to be sleeved, and the sleeving hole is provided with at least two positioning fixing notches allowing the positioning protruding blocks to be positioned. In the rotating process, the side sealing inclined ring edge is thrown away outwards relative to the center cover plate, air in a gap between the side sealing inclined ring edge and the shaft sleeve is guided to the end of the shaft sleeve and forms an air curtain diverging outwards, machining cuttings are blown away, liquid is prevented from entering the shaft sleeve, and the waterproof performance is good.

Description

technical field [0001] The invention relates to the technical field of machine tools, and more particularly, to a waterproof cover for a spindle. Background technique [0002] A machine tool refers to a machine that makes a machine, also known as a work machine or a machine tool, which generally uses cutting methods to process parts. There is a processing machine tool in the machine tool. The processing machine tool mainly drives the spindle and the tool to rotate and move through the rotating spindle to realize the drilling and cutting operations of the parts. The front end of the spindle is mostly installed on the processing machine tool with the front cover. [0003] At present, there is a waterproof cover structure for the main shaft of the machine tool on the market, see Figure 8 , the processing machine tool includes a main shaft 30, the main shaft 30 is provided with a shaft sleeve body 31, a mandrel body 32 and an outer cover body 33, the outer cover body 33 is made...
