Abstract
The utility model belongs to the technical field of cooling equipment for isostatic pressure graphite production processes, in particular relates to a main shaft for a material airing machine, which aims to solve the problem that the main shaft for the material airing machine is easily loosened to cause collision between reamers and damage a speed reducer. The main shaft for the material airing machine comprises a left shaft head, a right shaft head and a hollow shaft, wherein the left and right shaft heads are in interference fit with the hollow shaft; a plurality of fixing pins are arranged at joints of the left and right shaft heads and the hollow shaft. According to the main shaft for the material airing machine, a pin connecting mode is adopted, so that the main shaft can be assembled and disassembled for multiple times, and equipment maintenance and repair are facilitated; the left and right shaft heads are solid, and cannot be provided with pinholes generally, internal thread taper pins with taper of 1:50 can be used for effectively solving the problem of difficulty in assembly and disassembly, and can be self-locked, so that compared with a conventional welding mode, the pin connecting mode has the advantages that the shaft heads, the hollow shaft and the fixing pins are uniform in stress and stable in connection, and the condition that the reamers and the speed reducer are damaged due to the loosening and slipping of the main shaft of the material airing machine is effectively avoided.
Description
Technical field
The utility model belongs to the technical field of the cooling equipment in isostatic pressing formed graphite production technology, is specifically related to the one material owner axle that dries in the air.
Background technique
The material owner axle that dries in the air in isostatic pressing formed graphite workshop is to be formed by connecting by multistage axle at present, main shaft two ends are solid cylinder, centre is hollow tubular, when connection, adopt socket mode, and two ends solid shaft and hollow tubular joint are welded, but after the time of spindle operation one end, the contact wear of solid cylinder and hollow tubular, frictional force weakens, cause weld stress to concentrate aggravation, weld bond cracking, there is loosening even landing in the joint of solid cylinder and hollow tubular, causes the reamer on main shaft to bump.After reamer bumps, reamer all must be dismantled and reinstalled, have a strong impact on shopwork efficiency; If reamer and the speed reducer drying in the air in material machine bump, can directly damage speed reducer, thereby stability must guarantee spindle operation time.
Summary of the invention
The utility model is expected the easy loosening problem that causes reamer to bump against, damage speed reducer of owner's axle in order to solve to dry in the air, and proposition one is dried in the air and expected owner's axle.
The utility model adopts following technological scheme: one is dried in the air and expected owner's axle, comprises left spindle nose, right spindle nose and hollow shaft, and described left spindle nose, right spindle nose are connected with hollow shaft interference, and left spindle nose, right spindle nose and hollow shaft joint are provided with some fixing pins.
Described fixing pin is taper pin.
Described taper pin is taper pin with internal thread.
The utlity model has following beneficial effect: adopt pin Placement, can being dismounted for multiple times, be conducive to device maintenance, maintenance; Because left and right spindle nose is solid, pin-and-hole generally can not be opened, utilize taper pin with internal thread can effectively solve the problem of dismounting difficulty, and taper pin has the tapering of 1:50, can self-locking, compared with former welding manner, spindle nose, hollow shaft, fixing pin stressed more even, connect more stablely, effectively avoided that material owner axle is loosening because drying in the air, landing damages reamer, speed reducer.
Brief description of the drawings
Fig. 1 is traditional material owner axle construction of drying in the air;
Fig. 2 is structural representation of the present utility model
In figure: the left spindle nose of 1-, 2-fixing pin, 3-hollow shaft, the right spindle nose of 4-, 5-weld seam.
Embodiment
By reference to the accompanying drawings, embodiment of the present utility model is described further:
Fig. 1 is traditional material owner axle construction of drying in the air, and left spindle nose 1, right spindle nose 4 are connected with hollow shaft 3 interference, and in left spindle nose 1 and right spindle nose 4 outer walls and hollow shaft 3 junction welding, i.e. weld seam 5, when spindle operation, weld seam 5 places are stressed larger.
Fig. 2 is the structural representation of the material owner axle that dries in the air described in the utility model, comprise left spindle nose 1, right spindle nose 4 and hollow shaft 3, described left spindle nose 1, right spindle nose 4 are connected with hollow shaft 3 interference, and left spindle nose 1, right spindle nose 4 are provided with some fixing pins 2 with hollow shaft 3 joints.
Right spindle nose 4 is connected with motor, and left spindle nose 1 is connected with reamer, and the moment of motor output is passed to reamer by right spindle nose 4, fixing pin 2, hollow shaft 3, fixing pin 2, left spindle nose 1, makes reamer rotary turning graphite material.
Taper pin with internal thread is fixed on the joint of left and right spindle nose and hollow shaft, taper pin has the tapering of 1:50, can self-locking, and by cone, the effect of squeezing is fixed in the pin-and-hole that cuts with scissors light on left and right spindle nose, hollow shaft, and in the head of taper pin, have tapped hole, utilize the instruments such as screw to dismantle taper pin.
