Description

Device for dismounting disc spring pull rod of main shaft

Technical Field

The utility model relates to a mounting and dismounting tool, especially a device of dismouting main shaft dish spring pull rod.

Background

In the production process nowadays, the dismounting and mounting of the main shaft disc spring pull rod are completed by two persons. During disassembly and assembly, one person fixes the main shaft by using a tool at the front end of the main shaft to prevent the main shaft and the disc spring pull rod from rotating together, the other person uses a hammer, a chisel and the like to lock the end cover of the disc spring at the rear end of the main shaft in the machine tool and then destroys the disc spring and the disc spring pull rod, and the disc spring pull rod are taken out.

Above-mentioned working process not only needs the cooperation of two people, and the staff that is located the fixed main shaft of front end is because fixed main shaft does not have the stress point, and fixed hard and power consumption is big, and simultaneously the staff touches very easily when destroying dish spring locking end cover at the main shaft rear end and destroys other equipment components, and the dismouting operation that leads to current main shaft dish spring pull rod wastes time and energy, and in case destroy other equipment components, still can increase manufacturing cost.

SUMMERY OF THE UTILITY MODEL

For solving the problem that exists among the background art, the utility model provides a device of dismouting main shaft dish spring pull rod.

The purpose is achieved, the utility model adopts the following technical proposal: a device for dismounting a main shaft disc spring pull rod comprises a fastening positioning mechanism and a rotary dismounting mechanism; the tight positioning mechanism suit is in the outside of rotatory mechanism of disassembling, and tight positioning mechanism uses with main shaft and dish spring pull rod cooperation, rotatory mechanism of disassembling uses with dish spring locking apron cooperation.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model has the advantages of simple structure, low cost, the location is accurate, the flexible operation, can dismantle dish spring locking end cover under the condition of harmless other components, avoided the mistake to decrease other components, the destruction of dish spring locking end cover has been avoided, the disability rate of dish spring locking end cover has been reduced, manufacturing cost is reduced, the dismantlement change efficiency of dish spring pull rod has been improved, production efficiency is improved, U type frame is fixed for the main shaft front end provides the stress point simultaneously, make the operation only need alone can accomplish, personnel's waste has been avoided.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

A device for disassembling and assembling a disc spring pull rod of a main shaft comprises a fastening positioning mechanism and a rotary disassembling mechanism; the tight positioning mechanism suit is in the outside of rotatory mechanism of disassembling, and tight positioning mechanism uses with main shaft 8 and the cooperation of dish spring pull rod 9, rotatory mechanism of disassembling uses with the cooperation of dish spring locking apron 11.

The fastening and positioning mechanism comprises a connecting disc 1, a U-shaped frame 2 and a jacking screw rod 3; the open end of the U-shaped frame 2 is connected with the connecting disc 1 through a mounting screw 4, threaded holes are correspondingly formed in the middle of the main board of the U-shaped frame 2 and the middle of the connecting disc 1, and one end of the jacking screw rod 3 is screwed into the two threaded holes.

The rotary disassembling mechanism comprises a rotary sleeve 5 and a positioning pin 6; the rotating sleeve 5 is sleeved on the outer side of the front end of the jacking screw rod 3 and arranged in the U-shaped frame 2, and a plurality of positioning pins 6 are uniformly distributed at the front end of the rotating sleeve 5 along the circumferential direction of the rotating sleeve.

When the spindle is maintained in a Weiya 63G horizontal machining center, the disc spring pull rod is required to be disassembled to replace the disc spring without damaging the structure. Therefore, when the utility model is used, the positioning pin 6 of the rotary disassembling mechanism is inserted into the limiting hole of the disc spring locking end cover 11, so as to limit the disc spring locking end cover 11 to rotate; then, a connecting disc 1 of the fastening positioning mechanism is installed on the tail end of a main shaft 8 through a long screw 7, a jacking screw rod 3 is screwed in from a threaded hole in the center of the U-shaped frame 2, so that the front end of the jacking screw rod 3 jacks a disc spring pull rod 9 in the main shaft 8 to limit the rotation of the disc spring pull rod 9, and the disc spring pull rod 9 and a disc spring locking end cover 11 are prevented from rotating simultaneously; the connecting disc 1, the jacking screw 3 and the positioning pin 6 respectively limit the main shaft 8, the disc spring pull rod 9 and the disc spring locking end cover 11, so that the disc spring locking end cover 11 is prevented from being linked with the main shaft and the disc spring pull rod 9;

after the disc spring pull rod 9 is locked by the jacking screw rod 3, the rotary sleeve 5 is rotated through the space leaked outside the U-shaped frame 2, and then the disc spring locking end cover 11 is detached from the main shaft 8 a little by a little.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
