Description

Pneumatic shaft head dismounting device

Technical Field

The utility model belongs to the technical field of the disassembling equipment, concretely relates to inflatable shaft spindle nose dismounting device.

Background

In the raising stage of the splitting machine, because a certain gap exists between a winding cone gear ring and an air expanding shaft gear ring, and in addition, a centrifugal force is generated in the high-speed rotation process of an air expanding shaft, a positioning block fixing bolt has the problem of loosening and withdrawing, in the raising stage of the splitting machine, along with the increase of the motor torque, the end surface of a positioning block cannot be in maximum surface contact with the end surface of the winding cone, but the end surface of a bolt is in contact with the end surface of the winding cone, so that the stress area is reduced, and two surfaces generate relative friction in the raising process to cause the breakage of the bolt, after long-time friction, the end surface of the bolt and the end surface of the positioning block are in grinding and adhesion phenomena occur, because the bolt and the positioning block are both high in hardness and small in area of a shaft head, the shaft head is difficult to drill and break to replace the shaft head after the shaft head breaks, and simultaneously, thread damage is avoided, when the hand drill is installed on equipment, and the precision is difficult to ensure, the shaft head is not easy to be replaced by manual disassembly.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an inflatable shaft spindle nose dismounting device to solve the epaxial bolt screw thread fracture back of spindle, demolish the difficult scheduling problem of spindle nose.

In order to satisfy the above-mentioned purpose, the utility model discloses the technical scheme who takes does:

the utility model provides an inflatable shaft spindle nose dismounting device, includes the base, be equipped with the bracing piece on the base, the speed reducer is installed through the bearing frame in bracing piece upper end, and the speed reducer passes through the axis of rotation and is connected with the motor, the other end and the dismounting rod of speed reducer are connected, and the other end of dismounting rod is equipped with the sucking disc, sucking disc and the fixed plate phase-match of installing on the spindle nose, the sucking disc acts on the fixed plate.

Preferably, the fixing plate is fixed on the shaft head through a fixing bolt.

Preferably, the support rod and the dismounting rod are hydraulic telescopic rods.

Preferably, the size of the fixed plate is matched with that of the suction cup.

Preferably, the base is provided with a handle, and the bottom of the base is provided with a universal wheel with a braking function.

The utility model has the advantages that:

(1) the utility model discloses a through at disconnected silk the spindle nose upper mounting fixed plate, recycle fixed plate and rotatable sucking disc interact, dismantle the spindle nose, solved the manual work and dismantled the difficulty of operation.

(2) This equipment rotates through motor drive sucking disc and dismantles the spindle nose, reduces operation personnel's intensity of labour, has installed scalable bracing piece and the dismantlement pole that has the hydraulic pressure function simultaneously for its dismantlement work that adapts to not co-altitude environment has installed handle and universal wheel at the pedestal mounting, conveniently removes this equipment.

(3) The utility model discloses a well sucking disc acts on the fixed plate, and its fixed plate is installed through the original bolt hole of bolt and spindle nose, and it can this fixed plate of reuse, and the material of having avoided causing is extravagant.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure: 1. the device comprises a fixing plate, 2 parts of fixing bolts, 5 parts of shaft heads, 6 parts of motors, 7 parts of speed reducers, 8 parts of suckers, 9 parts of dismounting rods, 10 parts of supporting rods, 11 parts of bases and 12 parts of handles.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the working principle.

As shown in fig. 1, the device for disassembling the shaft head of the air expansion shaft comprises a base 11, a support rod 10 is arranged on the base 11, a speed reducer 7 is mounted at the upper end of the support rod 10 through a bearing seat, the speed reducer 7 is connected with a motor 6 through a rotating shaft, the motor 6 provides power for the speed reducer 7, the other end of the speed reducer 7 is connected with a disassembling rod 9, the speed reducer 7 drives the disassembling rod 9 to rotate, a sucker 8 is arranged at the other end of the disassembling rod 9, the sucker 8 is matched with a fixing plate 1 mounted on the shaft head 5, and the size of the fixing plate 1 is matched with that of the sucker 8; the sucking disc 8 acts on the fixed plate 1, and the dismounting rod 9 drives the sucking disc 8, and the sucking disc 8 acts on the fixed plate 1 to drive the fixing plate to rotate so as to achieve the purpose of dismounting the shaft head.

The fixing plate 1 is fixed on the shaft head 5 through a fixing bolt 2, and the fixing plate 1 is connected with a screw hole on the original shaft head 5 through a bolt, so that the fixing plate is simple and convenient to disassemble; the support rod 10 and the dismounting rod 9 are hydraulic telescopic rods, so that the dismounting device is suitable for dismounting in environments with different heights. Be equipped with handle 12 on the base 11, the bottom of base 11 is equipped with the universal wheel that has brake function, conveniently removes this equipment.

When using this equipment, at first remove this equipment to operation department, then fix fixed plate 1 through original screw and fixing bolt 2 on spindle nose 5, then adsorb the sucking disc 8 of high strength to fixed plate 1 on, treat after fixing the sucking disc, open motor 6, motor 6 drives speed reducer 7, drives the rotation of dismounting rod 9 again, and dismounting rod 9 drives the sucking disc 8 rotation at last to reach the purpose of dismantling spindle nose 5.
