The explanation of the utility model embodiment is not used to herein to limit the protection scope of the utility model.
Please refer to figs. 1 to 4, for press cushion block position-limit mechanism provided by the utility model include a board 10, one
A workbench 20 being placed on the board and at least one the limit assembly 30 on the workbench 20 is set.It can
With it is contemplated that the press cushion block position-limit mechanism further includes other functional modules, such as group arrangement, it is this field
Technology known by technical staff, is no longer described in detail one by one herein.
The board 10 includes at least one limit hole 11.The limit hole 11 cooperates with following spacer pins 33, is used for
Plug spacer pin 33.The quantity of the limit hole 11 should be corresponding with the quantity of the limit assembly 30, it is contemplated that
For limiting the relative position of two components, position-limit mechanism can be one, two, or it is more, in the present embodiment, institute
It states limit hole 11 and the limit assembly 30 is respectively provided with four.
The setting of workbench 20 cooperates on board 10 and with board 10, and the workbench 20 is including front 21 and instead
Face 22.The workbench 20 is for placing workpiece to be processed, therefore the structure of the workbench 20 and shape can be according to reality
Depending on needing, details are not described herein.
The limit assembly 30 includes a first interconnected hole 31 and second being arranged on the workbench 20
Hole 32, a spacer pin 33 being arranged in first hole 31, and steel ball 34, one is sequentially loaded into the second hole 32
A elastic component 35 and a screw 36.
First hole 31 is arranged on the longitudinal direction of workbench 20, and the transverse direction of workbench 20 is arranged in second hole 32.
Front 21 and reverse side 22 of first hole 31 through workbench 20, the second hole 32 is arranged in the side of workbench 20 and with first
The axis perpendicular in hole 31.First hole 31 can be a straight-tube shape through-hole, i.e., its in axial direction on diameter
It is equal.The diameter of the one end towards first hole 31 in second hole 32 is less than the diameter of the other end in second hole 32
It and is a ball-and-socket shape for accommodating the steel ball 34.Second hole 32 is additionally provided with backwards to the side in first hole 31
Screw thread 321 with the screw 36 to couple.
The spacer pin 33 includes two 331, one, column cap connecting rods 332 being arranged between two column caps 331, with
And two grooves 333 for being separately positioned on both ends of the connecting rod 332 close to column cap 331.The size and shape of the column cap 331
Shape can be suitable with the size and shape in first hole 31, and in the present embodiment, the column cap 331 and first hole 31 are all
For circle, and diameter is suitable.The axial length of the spacer pin 33 should be equal to the axial length of the limit hole 11.
The diameter of the steel ball 34 be less than second hole 32 towards 31 side of the first hole opening diameter so that
The steel ball 34 can be folded between the one end and the elastic component 35 in second hole 32 and the part of the steel ball 34 is stretched out
Second hole 32.The shape of the groove 333 is identical as the shape of steel ball 34.In cutting for the central axis along first hole 31
On face, the cross section contour of the groove 333 is arc, and the arc curvature is equal with the curvature of the steel ball 34, so that steel
Ball 34 cooperates even closer with groove 333.
The elastic component 35 can be spring, rubber etc..In the present embodiment, the elastic component 35 is accommodated in institute for one
State the spring in the second hole 32.
The screw 36 is arranged in second hole 32, so that the elastic component 35 is folded in the screw 36 and steel
Between ball 34, and then the elastic component 35 and steel ball 34 are fixed in second hole 32.
When the steel ball 34 is abutted with one in described two grooves 333, one in described two column caps 331 is inserted
Enter the relative position limited between the board 10 and workbench 20 in the limit hole 11 of the board 10, i.e., when the steel ball
34 with the groove 333 of side of the reverse side 22 close to workbench 20 when abutting, and spacer pin 33 is plugged in limit hole 11, to be
The relative position between board 10 and workbench 20 can be limited.And when the steel ball 34 and the one of the front 21 of close workbench 20
When the groove 333 of side abuts, the spacer pin 22 is the coupling being detached from the limit hole 11, to no longer will limit the board
With the relative position of workbench 20, and then can according to need to replace the workbench 20.
Compared with prior art, in the press cushion block position-limit mechanism of the utility model since spacer pin 33 includes respectively setting
The groove 333 for setting the both ends in the connecting rod 332 close to column cap 331, when in the steel ball 34 and described two grooves 333
When one abutting, to limit the board 10 in the limit hole 11 of an insertion board 10 in described two column caps 331
With the relative position between workbench 20.Simultaneously because the shape of the groove 333 is identical as the shape of steel ball 34, and along institute
On the section for stating the central axis in the first hole 31, the cross section contour of the groove 333 is arc, the arc curvature and the steel
The curvature of ball 34 is equal, so as to so that the cooperation between groove 333 and steel ball 34 is even closer, so that press is using
When, no matter the workbench 20 be it is horizontal positioned or it is vertical place, all will not because of machine vibration and make the spacer pin
33 groove 333 is detached from the steel ball 34, so as to improve stability.
The above is only the preferred embodiments of the utility model, are not used to the limitation protection scope of the utility model, any
Modification, equivalent replacement or improvement within the spirit of the present invention etc. are all covered in the scope of the claims of the utility model.
