Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing and have
The utility model is described in further detail for body embodiment.
The utility model includes mounting base 1 and two groups of deformation limit assemblies being arranged in mounting base 1 and a position
Limit assembly.As shown in Figure 1, two deformation limit assemblies bilateral symmetries and being arranged at intervals in mounting base, position limit assembly
The front position for deforming on limit assembly line of symmetry 11 positioned at two and being positioned close to mounting base.Flexibility can be accommodated in order to be formed
The space of bearing 7, so there are spacing between two groups of deformation limit assemblies.The purpose of two groups of deformation limit assemblies is to squeeze soft
Property bearing 7 deform, until become meet adaptation cam ellipse.And the purpose of position limit assembly is then to limit flexible bearing 7
Position in mounting base 1, so that it will not displacement is generated when being pressed with cam.
Position limit assembly and deformation limit assembly are described in detail below, specific as follows:
As depicted in figs. 1 and 2, deformation limit assembly includes time interval and the lateral strip-shaped holes 5 of two in parallel and one
The distortion spacing block 6 of bar shaped, there are two screw hole 601, the spacing of two screw holes 601 and two lateral bar shapeds on limited block 6
The spacing in hole 5 is equal.Lateral strip-shaped hole 5 is arranged in mounting base 1.The axis of lateral strip-shaped hole 5 is vertical with line of symmetry 11.Becoming
In shape limit assembly, distortion spacing block 6 is connect by two lock-screws 4 with former and later two lateral strip-shaped holes 5 respectively.Locking screw
Nail 4 realizes locking equipped with locking nut 9.When distortion spacing block 6 needs to slide deformation, loosen two lock-screws 4, deformation limit
Position block 6 can horizontally slip along former and later two lateral strip-shaped holes 5.It, will when distortion spacing block 6, which slides into suitable position, to be needed to position
Two lock-screws 4 screw.The length of former and later two lateral strip-shaped holes 5 is identical, and corresponding end flushes.Due to two groups of deformations
There are spacing between limit assembly, so there are spacing between the lateral strip-shaped hole 5 in corresponding left and right two.Former and later two transverse directions
The interval of strip-shaped hole 5 is greater than the interval of the lateral strip-shaped hole 5 in left and right two.Have between screw hole 601 and the screw rod of screw 4 biggish
Gap, the gap can permit the adjustment space for having 3 °~10 ° angles between distortion spacing block 6 and line of symmetry 11.
As shown in figures 1 and 3, position limit assembly includes location hole 10 and position limited block 2.The setting of location hole 10 is being pacified
It fills on seat 1.Position limited block 2 is bar blocks, and position limited block 2 is vertically positioned between two groups of deformation limit assemblies, position limit
Minimum spacing between less than two distortion spacing blocks 6 of the width of block 2.Longitudinal strip-shaped hole 3 is equipped on position limited block 2.Position
Limited block 2 is set to connect by the lock-screw 4 being plugged in strip-shaped hole with location hole 10.Wherein, the central point of location hole 10 with
And the axis of longitudinal strip-shaped hole 3 is overlapped with line of symmetry 11.In order to keep the utility model compact-sized, location hole 10 is designed as spiral shell
Pit, the lock-screw 4 on position limited block 2 can be directly threadedly coupled with location hole 10, without separately setting nut.Position limit
Block 2 can be slid back and forth by lock-screw 4 along strip-shaped hole.
Position limited block 2 positioned at 1 middle line front of mounting base and two deformations limit positioned at 1 middle line of mounting base or so
Block 6, because spaced, three limited blocks define the space that can accommodate flexible bearing 7.And this space is
Shapes and sizes can be changed with the movement of three limited blocks.
When the utility model is used, the course of work is as follows:
In the flexible bearing 7 and cam for pressing a kind of model, firstly, by the lock-screw 4 and two on position limited block 2
Lock-screw 4 on a distortion spacing block 6 loosens, and enables three limited block slide displacements.Secondly, flexible bearing 7 is put into
In the space that three limited blocks surround, the location of three limited blocks are adjusted by coarse positioning, until 7 energy of flexible bearing
It is enough to complete to press with corresponding cam；Again, it is locked after being finely adjusted according to the flexible bearing 7 pressed to corresponding limited block；
Finally, in flexible bearing 7 of the pressing with model, it is only necessary to flexible bearing 7 is placed in mounting base 1, limited from two deformations
The opening at 6 rear of block above pushes away, until 7 outer circle of flexible bearing touches the front end face of position limited block 2, then with cam major diameter pair
7 major diameter of flexible bearing after quasi- deformation, gently pressure can be completed on press machine.
To replace the flexible bearing 7 and cam of different model, it only need to loosen three limited blocks, repeat above-mentioned steps i.e.
It can.
Entire replacement process need to only be can be completed using a set of tooling, effectively reduce the cost of equipment.And the side of operation
Just quick.
Since the lock-screw 4 on distortion spacing block 6 needs to complete locking by locking nut, for entire tooling knot
The compactedness of structure considers, therefore increases a limit sliding chutes 8.On the one hand locking nut can be accommodated, on the other hand can limited
The rotation of locking nut facilitates screwing and loosening for lock-screw 4, and the specific structure of limit sliding chutes 8 is as follows: lateral strip-shaped hole 5
Bottom be equipped with the limit sliding chutes 8 that penetrate through with it；
As shown in Figures 2 and 3, the bottom of lateral strip-shaped hole 5, that is, the back in mounting base 1 is arranged in limit sliding chutes 8
Face, limit sliding chutes 8 and lateral strip-shaped hole 5 penetrate through.In order to avoid extra protrusion occurs in 1 back side of mounting base, so limit sliding chutes 8
For deep gouge.The sum of the thickness of limit sliding chutes 8 and the thickness of lateral strip-shaped hole 5 are the thickness of mounting base 1；The middle line of limit sliding chutes 8
It is overlapped with the middle line of lateral strip-shaped hole 5, but the length of limit sliding chutes 8 and the wide length and width for being all larger than lateral strip-shaped hole 5, each position
Difference it is unified.In limit sliding chutes 8, the lock-screw 4 on distortion spacing block 6 is connect locking nut 9 with locking nut 9.
On the one hand limit sliding chutes 8 limit the rotation of locking nut 9, on the other hand make locking nut 9 can be along limit sliding chutes 8 and lock-screw
4 slide together.
