Background technology
In the manufacture process of motor, include the operation in the bearing block of bearing pressing machine shell, in the prior art,
It is usually and first casing is horizontally fixed on base, then make the bearing block of casing straight up, then bearing is put into
In the bearing block of casing, the most manually make to press under staking punch, by staking punch by the bearing block of bearing pressing machine shell, by
Need manual depression staking punch in current bearing press mounting process so that press-fit inefficient, and bearing is being pressed into axle
During holding, once casing is not set level whole, it will make bearing block be not located in state straight up, and punching press
Head is impulse bearing straight down, and bearing block thus can be made deform, it is impossible to firmly by bearing press mounting at bearing
In seat.
Summary of the invention
The technical problem to be solved is to provide that to press-fit efficiency higher, and can be during pressing bearing
The position of automatic adjusting machine shell makes the bearing press-fitting device of casing horizontal positioned.
For solving above-mentioned technical problem, the bearing press-fitting device that the present invention provides, it includes that workbench, workbench are provided with
Slideway, is provided with the base that can slide along slideway in slideway, being arranged over staking punch and drive the dynamic of staking punch action of slideway
Power apparatus, the rear end of slideway is provided with for the limited block of spacing base with for controlling the microswitch that power set start；
Described base includes lower supporting plate and the upper backup pad be arrangeding in parallel, and lower supporting plate is provided with support seat, supports seat
Being provided with the location bar arranged straight up, upper backup pad is located at the top of lower supporting plate, and the interposition of upper backup pad installs
Having the first through hole, in the range of supporting the upright projection that seat is positioned at the first through hole, location bar is arranged in the first through hole, supports
The upper surface of seat, less than the upper surface of upper backup pad, is provided with balance buffering mechanism between upper backup pad and lower supporting plate；
Described balance buffering mechanism includes at least three guide posts being vertically arranged in the upper surface of lower supporting plate, upper support
Plate is provided with second through hole corresponding with each guide post, and each guide post is all slidably arranged in corresponding second through hole,
The aperture of the second through hole, slightly larger than the diameter of guide post, each guide post is all arranged with stage clip, and the lower end of each stage clip is equal
Offseting with the upper surface of lower supporting plate, the upper end of each stage clip all lower surfaces with upper backup pad offset；
When above-mentioned bearing press-fitting device uses, first make base be in the front end of slideway, location bar is located in the bearing of casing
In seat, make casing be placed on upper backup pad, enter to position bar by the most sheathed for bearing the most again so that bearing is placed
Above the bearing block of casing, base is then promoted to make base slide into the rear end of slideway, until lower supporting plate and limit
Position block offsets so that base cannot continue forward slip, at staking punch and location bar on the same axis now, and now
Base touches microswitch and microswitch is triggered, and power set start to drive under staking punch presses, staking punch gradually under
During pressure, location bar gradually stretches in the axial hole of staking punch, after staking punch is depressed into certain position, and staking punch and bearing
Contact, staking punch applies downward pressure to bearing, and bearing is progressively pressed in the bearing block of casing, and now upper
Fagging is gradually pressed down by downward pressure, during upper backup pad is pressed down, and upper backup pad automatic adjustable balance,
The bearing block making casing is directed at bearing.
As improvement, described slideway is provided with the groove of some the rear ends all extending to slideway from the front end of slideway.
As improvement, the position of the front end of the close slideway of described lower supporting plate is provided with push rod.
After using above structure, the present invention compared with prior art, has the advantage that
1, the present invention presses by under air cylinder driven staking punch, compared to manual depression staking punch of the prior art, press-fits
Efficiency is largely increased, and when pressing bearing, first casing is placed on upper backup pad, when by pressure under bearing,
Owing to being provided with balance buffering mechanism between upper backup pad and lower supporting plate, upper backup pad can move down, upper backup pad to
During lower movement, upper backup pad automatic adjustable balance makes casing be horizontal so that bearing block keeps vertically
State upwards, so that bearing is pressed in bearing block by the staking punch of punching press straight down smoothly, so that bearing
The most firmly it is fitted in the bearing block of casing.
2, being provided with groove due to slideway so that when base slides in slideway, lower supporting plate subtracts with the contact area of slideway
Little, so that the frictional force reduction that lower supporting plate is suffered when sliding so that it is easier to promote base to slide.
3, being provided with push rod, operator can promote base to slide by push rod, so that operator need not touch
Touch base, operate more convenient, the most safer.
