Technical Field

The utility model relates to a polishing processing equipment technical field, concretely relates to quick assembly disassembly throws aureola subassembly.

Background

Today, polishing is widely used as a process means for improving appearance effect of a metal workpiece, and polishing wheel assemblies are used for polishing in polishing equipment, for example, as shown in fig. 3: the polishing machine comprises a polishing wheel 15, a locking nut 16 and a stud bolt 17 which is in threaded connection with the locking nut, wherein the stud bolt is connected with a machine tool spindle, and the polishing machine is also improved by adding a compression spring 14 shown in the drawing and used for adjusting the contact pressure between the polishing wheel and a workpiece to be polished.

However, the connection process of the stud bolt and the spindle takes a long time, and under the action of the compression spring, if the connection process is not maintained for a long time, the problem of bolt connection loosening occurs, and a mechanism for locking the connection position between the stud bolt and the spindle of the machine tool is also lacked, so the existing technical scheme still needs to be improved.

Disclosure of Invention

The utility model discloses the purpose is: to current connection process between throwing aureola subassembly and the lathe main shaft consuming time, the relation of connection does not have locking mechanical system, permanent overhaul comes off easily and injures personnel's problem, we design and propose a quick assembly disassembly throws aureola subassembly, adopt convenient bayonet lock mechanism, peg graft on the lathe main shaft with the integrative shaft hole of throwing aureola subassembly, and through pressure spring, both adjust the contact pressure who throws aureola and wait to polish between the work piece, cooperate the rotatory degree of freedom of elastic gasket restriction throwing aureola again, practicality is convenient, it is swift high-efficient to peg graft, lock state is stable, be difficult for droing, therefore, the clothes hanger is strong in practicability.

The technical scheme adopted for solving the problems is as follows:

a quick-assembly-disassembly polishing wheel component comprises a shaft seat connected with a machine tool spindle, a polishing wheel, a pressing spring and a bayonet lock mechanism,

the shaft seat is T-shaped and comprises a base and a connecting shaft which are integrally connected, the shaft seat penetrates through the central hole of the polishing wheel and then is matched with the shaft hole of the elastic washer, the upper part of the elastic washer is also sleeved with a compression spring, the upper end of the compression spring is also sleeved with a locking washer with the connecting shaft,

the utility model discloses a lathe main shaft, including lathe main shaft lateral wall, the bayonet lock mechanism sets up in the through-hole that radially link up connecting axle upper portion, bayonet lock and reset spring that sets up including the symmetry to and closely cup joint the dropout on lathe main shaft lateral wall and press the gum cover, the dropout is pressed the gum cover and is included the lantern ring, is connected the adhesive tape and is pressed the briquetting, press the briquetting position to aim at the bayonet lock position.

Furthermore, the outer ring of the compression spring is further sleeved with a telescopic dust cover, and the telescopic dust cover can axially stretch and retract to completely shield the compression spring from being invaded by external impurities.

Furthermore, the locking washer is integrally connected and fixed with the lower end of the machine tool spindle.

Furthermore, the connection part of the tail parts of the two return springs is provided with a positioning column, and the positioning columns are tightly matched and positioned after radially penetrating through the connecting shaft.

The utility model has the advantages that:

this quick assembly disassembly throws aureola subassembly adopts convenient bayonet lock mechanism to peg graft the connecting axle shaft hole of axle bed on the lathe main shaft to both adjust through pressure spring and throw aureola and treat the contact pressure between the polishing work piece, cooperate the rotatory degree of freedom that elastic gasket restriction thrown aureola again, practical convenient, it is swift high-efficient to peg graft, and locking state is stable, is difficult for droing, and the practicality is strong.
