Description
Technical field
The utility model relates to a kind of fixture, in particular to a kind of reverse gear synchronizer baffle pressing clamp.
Background technique
Since transmission input shaft and output shaft are rotated with respective speed, there are one " synchronizations " to ask for conjunction when converting gear
Topic.Two different gears of rotation speed engage by force will necessarily occur impact, damage gear.Therefore, old-fashioned speed changer
Gear shift to upshift and be stopped a moment in neutral position by the way of " bipod clutch ", downshift will in neutral position open out, with
Reduce the rotational speed difference of gear.But this operation is more complicated, it is difficult to grasp accurate.Therefore designer creates " synchronizer ", leads to
Crossing synchronizer makes that meshed gears will be wanted to reach consistent revolving speed and smoothly engage.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
A kind of reverse gear synchronizer baffle pressing clamp as shown in Fig. 1 to 3 has pedestal 1, and the upper end of pedestal 1 is provided with
Middle set 2 annular in shape, the upper end of middle set 2 are provided with spline housing 6, and internal spline, the top of middle set 2 are provided on the inner wall of spline housing 6
End middle part is upward, and forms table top, and middle set 2 is provided with movable axis 3 moving up and down, the lower end surface and bottom of movable axis 3
It is provided with reset spring 4 between seat 1, the lower end surface of movable axis 3 and the upper surface of pedestal 1 are provided with for pacifying spring-loaded bullet
Spring hole, and the upper and lower ends of reset spring 4 are respectively placed in inside two spring eyes.Spring eye on jack 3b and movable axis 3 connects
It is logical.It is formed with the step 3a for being used to support workpiece in the middle part of the periphery of movable axis 3, the upper end of movable axis 3 upwardly extends, and reaches
Outside spline housing 6, the upper end center of movable axis 3 is provided with the jack 3b to feel relieved for compression plate 5 from top to bottom；Compression plate 5 includes
Center pillar 5a, center pillar 5a can be adaptedly inserted into jack 3b, platen body 5b is provided in the middle part of center pillar 5a, platen body 5b is in
Column 5a is vertical, and the lower end surface of platen body 5b is provided with multiple pressings 7, and the circumferentially uniformly arrangement of multiple pressing 7, with the pressing
7 one by one it is vertical just over the ground, and be provided with plunger 8 on the table top that middle 2 upper end of set is formed.
As shown in Fig. 1 to Fig. 3, structure type as one preferred, movable axis 3 divides for upper shaft part 3c and lower shaft part 3d,
The outer diameter of upper shaft part 3c is less than the outer diameter of lower shaft part 3d, and the upper surface of lower shaft part 3d constitutes step 3a.The periphery of lower shaft part 3d
Limit baffle ring 3da is formed at lower part, and ground is adapted with limit baffle ring 3da, is formed with limited step 2a in the inner wall of middle set 2.
The principles of the present invention and operating process are as follows:
Pedestal 1, middle set 2 and spline housing 6 are mounted for an entirety first, and middle section is used to that movable axis 3 and peace is arranged
Toothing hub.Tooth hub and baffle namely need the workpiece fixed by press fitting rivet, and tooth hub and baffle by driving the rivets to be formed in advance
Initial component state.Sub-assembly installation is oriented to by tooth hub and the spline on spline housing 6, to realize radial be precisely located
Installation.Tooth hub is supported by 3 step of movable axis.During pressing, the center pillar 5a of compression plate 5, which is inserted into jack, realizes compression plate
Radial positioning, and the rivet on tooth hub is oppressed by the plunger 8 on the pressing 7 and middle set 2 on platen body 5b, complete to tooth hub and
The riveting of baffle is pressed.In the specific implementation, pedestal 1, middle set 2 and spline housing 6 are an entirety being bolted,
During three installations are integral, the related assembly together of movable axis 3 is entered, needs limit baffle ring 3da snapping fitted to limit
Position step 2a is hereinafter, the limit for being easy to implement the later period stops.Be set with the tooth hub of baffle in placement process by spline housing 6 into
Row guiding normotopia, convenient for pressing 7 and plunger 8 to positive rivet.Tooth hub is supported on step 3a, after placing, in the process of pushing
In, the lower end of center pillar 5a is inserted into the jack 3b of 3 upper end of movable axis, and lucky platen body 5b and tooth hub are opposite, under platen body 5b
End face is contradicted to the upper surface of tooth hub, and continues to press down.Tooth hub moves down together against movable axis 3 simultaneously.Due to
Rivet on pressing 7, plunger 8 and tooth hub is all position face one by one, and therefore, this pressing action makes rivet end generate modeling
Property deformation, to realize that the riveting of tooth hub and baffle is fixed.It is provided with reset spring 4 between movable axis 3 and pedestal 1, works as activity
When axis 3 is oppressed downwards, it can be reversed homing action by reset spring 4, the upward position of movable axis 3 is helped to reset, and
The be crushed out of shape combination end face of nipper hub and baffle of rivet forms good contact, it is ensured that the assembling quality of the two.Meanwhile multiple
In this movement of position, limited by limit baffle ring 3da and limited step 2a cooperation.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
