SUMMERY OF THE UTILITY MODEL
The technical problem that this application will be solved is that the inertia moment of grinding the section when angle mill shuts down acts on lock nut, can drive lock nut and continue rotary motion, has the potential safety hazard that breaks away from out the output shaft.
In order to solve the technical problems, on one hand, the technical scheme of the application provides a structure for integrating a rotating shaft and a flange pressing plate, and the structure comprises an output shaft for connecting an angle grinder and a grinding sheet, wherein the rear end of the output shaft is connected with the angle grinder, and the front end of the output shaft is connected with the grinding sheet and a locking nut; the rotating direction of the output shaft is used as the positive direction, the outer wall of the wedge-shaped flange is provided with an outer inclined plane rotating in the positive direction, and the inner wall of the clamping flange is provided with an inner inclined plane matched with the outer inclined plane.
The inner inclined surface of the clamping flange is in contact with the outer inclined surface of the wedge-shaped flange for limiting; the clamping flange rotates forward and moves towards the rear end under the limit of the inclined plane, and the clamping flange rotates reversely and moves towards the front end under the limit of the inclined plane.
Preferably, the end face of the clamping flange, which is tightly attached to the grinding slice, is a leather grain face, that is, the end face is provided with linear protrusions distributed in a crossed manner.
Preferably, snap springs are arranged at the positions where the clamping flange and the output shaft are sleeved and between the clamping flange and the output shaft.
On the other hand, the technical scheme of this application still provides an angle mill, and angle mill adopts foretell structure connection grinding section of integrating rotation axis and flange clamp plate.
This application advantage lies in, angle mill is at high-speed operation and the in-process that stops rapidly, presss from both sides tight flange and wedge flange relative motion and produces the displacement at axial normal direction to increase the locking force who presss from both sides tight flange and lock nut, the tight flange surface of clamp has dermatoglyph effect plane simultaneously, has increaseed the frictional force who presss from both sides tight flange and grind the section, and more reliable locking grinds the section, avoids lock nut not hard up, solves the safety problem.

Detailed Description
In order to make the present application more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
Examples
The embodiment provides a structure integrating a rotating shaft and a flange pressing plate, which realizes locking of a grinding sheet when an angle grinder is stopped and prevents the grinding sheet from falling off, as shown in fig. 1 and 2, the rear end of an output shaft 1 is connected with the angle grinder through an angle grinder head shell locking flange 8, and the front end is used for connecting the grinding sheet and a locking nut; there is a support step at output shaft 1's middle part, self-supporting step overlaps in proper order to the front end on output shaft 1 and establishes wedge flange 4, press from both sides tight flange 3, grind section 6 and lock nut 5, press from both sides tight flange 3 some cover and establish outside output shaft 1, another part cover is established outside wedge flange 4, the position of establishing is established at pressing from both sides tight flange 3 and output shaft 1 cover, be provided with jump ring 2 between tight flange 3 and the output shaft 1, the axiality between adjustable tight flange 3 of clamp of jump ring 2 and the output shaft 1, avoid the atress skew to lead to the frictional force increase.
The rotating direction of the output shaft 1 is taken as the forward direction, the position where the clamping flange 3 is nested with the wedge-shaped flange 4 and the outer wall of the wedge-shaped flange 4 are provided with forward rotating spiral outer inclined planes, the inner wall of the clamping flange 3 is provided with an inner inclined plane matched with the outer inclined plane, and when the clamping flange is installed, the inner inclined plane of the clamping flange 3 is in contact with the outer inclined plane of the wedge-shaped flange 4 for limiting, and the clamping flange is similar to threaded connection; the forward rotation clamping flange 3 moves towards the rear end under the limit of the inclined plane, and the reverse rotation clamping flange 3 moves towards the front end; the end face of the clamping flange 3, which is close to the grinding sheet 6, is provided with a leather-grain surface 31, as shown in fig. 3, that is, the end face is provided with linear protrusions distributed crosswise, so as to enhance the friction force of the contact between the clamping flange 3 and the grinding sheet 6.
As shown in fig. 2, the wedge-shaped flange 4 is press-fitted onto the output shaft 1 in an interference fit manner, then the clamping flange 3 is installed so that the inner inclined surface of the clamping flange 3 abuts against the outer inclined surface of the wedge-shaped flange 4, then the grinding sheet 6 is installed so that the grinding sheet clings to the leather grain surface of the clamping flange 3, and finally the locking nut 5 is installed to lock all structures.
The rotary motion function and the locking principle of the embodiment are as follows: when the rotary motion of the angle grinder is stopped, the inertia moment of the grinding and cutting sheet 6 acts on the clamping flange 3 and drives the clamping flange 3 to rotate reversely, and the surface dermatoglyph of the clamping flange 3 increases the rotary friction force between the clamping flange 3 and the component 6, so that the two components are prevented from sliding relatively; when the clamping flange 3 rotates reversely, the inner inclined surface of the clamping flange 3 makes the clamping flange 3 displace towards the front end under the limit of the outer inclined surface of the wedge-shaped flange 4, and the axial displacement makes the clamping flange 35 and the locking nut more firmly lock the grinding sheet 6.
