Abstract
Automobile engine crankshaft gear and sprocket wheel press-in device, all directions uniform force in process of press in can not be effectively ensured by overcoming the press-in device of existing crankshaft toothed wheel and sprocket wheel, easily occurs bias with bent axle, it is easily caused gear and sprocket wheel press-in device is biased, cause scrapping for bent axle, press-fit low success rate of problem, it is characterized in that support base is installed on line slideway, fixed cover is installed in support base, pressure head is installed in fixed cover, spring is installed in pressing head seat, seeker is installed in the right-hand member of pressure head, pressure head is connected locking with locking nut with servo cylinder pressure by being connected section, beneficial effect is, employ two line slideways, pass through support base, fixed cover and seeker it is spacing, it ensure that pressure head moves along a straight line all the time under the driving of servo cylinder pressure, so as to ensure that in the process of press-in bent axle the phenomenon with crankshaft eccentric will not occur for gear and sprocket wheel, it ensure that in process of press in middle gear and sprocket wheel be uniform stressed all the time, press-fit success rate so as to improve.
Description
Technical field
The utility model belongs to automobile engine crankshaft gear mounting technology field, and more particularly to a kind of automobile engine is bent
Shaft gear and sprocket wheel press-in device.
Background technology
Automobile engine crankshaft assembling gear and sprocket wheel are the essential procedures of Production of Crankshaft, and gear and sprocket wheel are logical
Interference fit is realized with the small head end of bent axle and assembled, because intrusion is larger, thus to process of press in middle gear and sprocket wheel with
The concentricity requirement of the small head end of bent axle is higher, in the prior art, and the press-in of gear and sprocket wheel uses special tooling, coordinates general pressure
Machine is press-fited, and special tooling uses imitated structure, does spacing using the profile of gear and sprocket wheel, and this special tooling is for convenience of upper
Material, the gap between frock and gear and sprocket wheel is larger, and when being press-fited, gear and sprocket wheel can shift in frock, institute
Can not effectively ensure all directions uniform force of gear and sprocket wheel during press-fiting, make gear and sprocket wheel and bent axle easy
Generation is eccentric, so as to cause gear and sprocket wheel to bias, directly results in scrapping for bent axle.
The content of the invention
Problem to be solved in the utility model is to overcome the deficiencies in the prior art part to be pressed into defect there is provided one kind
Power is uniform, it is ensured that concentric at process of press in middle gear and sprocket wheel moment and bent axle, and the automobile engine for improving press-in success rate is bent
Shaft gear and sprocket wheel press-in device.
The technical solution adopted in the utility model includes mounting base, and fixed board and front and rear 2 is installed on mounting base
Individual line slideway, is fixedly connected with servo cylinder pressure on riser, support base is installed on front and rear 2 line slideways, in support base
Fixed cover is installed, pressure head is installed in fixed cover, the pressure head includes pressing plate and pressing head seat, bullet is installed in pressing head seat
Spring, seeker is installed in the right-hand member of pressure head.
The pressure head is fixedly connected with the piston rod of servo cylinder pressure by being connected section with locking nut.
The support base is interference fit with fixed cover, and the pressure head coordinates with seeker gap.
Compared with prior art, the beneficial effects of the utility model are to employ two line slideways, by support base,
Fixed cover and seeker it is spacing, it is ensured that pressure head moves along a straight line all the time under the driving of servo cylinder pressure, so as to ensure that
In the process of press-in bent axle the phenomenon with crankshaft eccentric will not occur for gear and sprocket wheel, it is ensured that in process of press in middle gear and chain
The all directions of wheel are uniform stressed all the time, and success rate is press-fited so as to improve, and reduce production cost.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in drawings, the technical solution adopted in the utility model includes mounting base 1, is provided with mounting base 1
Fixed board 2 and front and rear 2 line slideways 3, servo pressure is fixedly connected with riser 2 by cylinder pressure fixed plate 5 with fixing screws 6
Cylinder 4, installs support base 10 on front and rear 2 line slideways 3, and fixed cover 11 is installed by being interference fitted in support base 10, leads to
Cross gap and coordinate installation seeker 12, pressure head 9 is installed by being interference fitted, the pressure head 9 includes pressing plate 9-1 and pressing head seat 9-2,
Spring 13 is installed in pressing head seat 9-2, to realize the Telescopic of seeker 12, the piston of the pressure head 9 and servo cylinder pressure 4
Bar is connected locked by connection section 8 with locking nut 7, to realize that the drive ram 9 of servo cylinder pressure 4 is moved along a straight line.
In use, a module and bent axle automatic press mounting equipment phase of the utility model as bent axle automatic press mounting equipment
Even, its course of work is：
（1）Manually or mechanically timing gears are placed on seeker 12 by hand；
（2）Servo cylinder pressure 4 is moved right by connecting section 8 and the drive ram 9 of locking nut 7；
（3）Pressure head 9 makes seeker 12 do straight line fortune along line slideway 3 by fixed cover 11, spring 13 and support base 10
Dynamic, seeker 12 is fitted and dieback with bent axle small end；
（4）Pressure head 9 continues to move right, and the compression spring 13 of seeker 12 is simultaneously retracted timing gears edge in pressing head seat 9-2
Seeker 12 to be fitted on bent axle；
（5）After the completion of press-fiting, servomotor 4 is moved to the left home position, and pressure head 9 is separated with timing gears, seeker
12 separate with bent axle, and spring 13 resets ejects pressure head 9 by seeker 12；
（6）Sprocket wheel is placed on seeker 12, repeated above-mentioned（2）（3）（4）With（5）Process sprocket wheel can be press-fited
On bent axle.
