Abstract
The invention provides an application method for a guide sleeve in long-barrel part press-in assembling, which is a vertical press-in assembling method for improving the guide of the guide sleeve. The application method specifically comprises the steps of: restraining the lateral degree of freedom of a press-in part by the guide sleeve; preventing the center line of the press-in part and the center line of a pressed-in part from inclining so as to perform a guide action on the press-in part; and in the press-in assembling process, pressure is vertically acted on the press-in part of which the lateral degree of freedom is restricted by the guide sleeve via a press-in die by a hydraulic press block so as to realize the press-in assembling of the press-in part. According to the method, the operation is convenient and the master is easy. The application method comprises the specific steps of installing, press fitting and detecting. Because the application method for the guide sleeve in long-barrel part press-in assembling adopts a press fitting method that the lateral degree of freedom of a press-in part is restrained by the guide sleeve to guide, the product percent of pass in the press-in assembling process is effectively improved, and the assembling quality is guaranteed.
Description
Technical field
The present invention relates to the assembling field that is pressed into of long barrel part, particularly be pressed into part and its center line easily occur with respect to the place of the center line run-off the straight that is pressed into part in put procedure.
Background technology
Be pressed at present the assembling range of application very extensive in many products.As VLB, the VLBL series flame proof vibrating motor that Zhongxiang Xinyu Electrical and Mechanical Manufacturing Co., Ltd. produces, its housing just belongs to pressure being connected of winding stator core and assembles with having.This series flame proof vibrating motor is a kind of slim-lined construction vibrating motor (hereinafter to be referred as long-rod motor), and exciting force application point distance (distance in lower margin hole) extra wide, for the especially practicality of occasion that requires to transmit in wide distance exciting force.This type of vibrating motor is equipped on vibrating machine, can make the vibrating machine operation more steady, and member stress is more even, effectively extends the useful life of vibrating machine.It is widely used as the grade vibration source of vibratory equipment of vibrating feed, vibrating transportation, vibrating screen, both can be used alone, also use capable of being combined.Be widely used in the departments such as mine, metallurgy, chemical industry, electric power, building, oil field.
But, because of VLB, VLBL series flame proof vibrating motor housing with have the assembling of winding stator core to belong to being pressed into assembling, in its assembling process owing to there being winding stator core inevitably to there will be tilt phenomenon when placing, acted directly on winding stator core and hydraulic press pressure is pressed into mould by hydraulic press briquetting and special use, thereby caused having the damage of winding stator core in press-fiting process.Owing to being pressed into the scrappage that winding stator core is arranged that causes of assembling up to 30%-50%.
Therefore, be necessary to develop a kind of novel assembly method that is pressed into.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and realize being pressed into part and the assembly method that is pressed into that is pressed into part to increase fairlead, the method is simple to operate, is easy to grasp.
The present invention solves its technical problem and adopts following technical scheme:
The application process of fairlead provided by the invention in long barrel part is pressed into assembling, it is a kind of vertical assembly method that is pressed into that increases the fairlead guiding, specifically: utilize fairlead to use restraint to the horizontal degree of freedom that is pressed into part, make to be pressed into the center line and the not run-off the straight of center line that is pressed into part of part, to play being pressed into the guide effect of part; In being pressed into the process of assembling, the hydraulic press briquetting vertically acts on pressure by guide sleeve laterally limiting being pressed on part of its horizontal degree of freedom by being pressed into mould, with this, realizes being pressed into the assembling that is pressed into of part.
The operating procedure of the method comprises:
