Description
Technical field
The present invention relates to a kind of detent mechanism, the positioning particularly to a kind of fixture being applicable on building-block machine supports
Mechanism.
Background technology
Fixture is building-block machine important composition parts, is the specific requirement of the technique according to lathe and organization plan and special
Design.It is for realizing being accurately positioned of part to be processed, clamps, the guiding of cutter, and spacing during workpiece loading and unloading
Etc. effect.Fixture for modular machine typically will bear bigger cutting force, and its structure is also more complicated, is to ensure that again processing essence
One of main parts of degree.Thus the precision improving fixture just seems particular importance.
According to the major function of fixture for modular machine, its structure can be divided into positioning support system, clamp system, cutter to lead
To grade three parts.Positioning support system, as the important component part of fixture, plays important when processing on building-block machine
Effect, not only part to be processed to be ensured to cutter and guides the relative position keeping correct, still suffers from part to be processed
Weight, clamping force and cutting force.Owing to positioning support element directly contacts with part to be processed, therefore its size, structure, essence
Degree and arrangement all directly affect the precision of part to be processed.The support level of existing positioning support system in one plane, and
The area of this support level is relatively big, needs part to be processed to have enough by supporting and space, to accommodate positioning support system.Some quilts
Processing part is limited because of positioning and processing, needs position in irregular shape of positioning support, is difficult to arrangement positioning support position；
Existing positioning support system cannot employ, it is therefore desirable to develops a kind of novel supporting mechanism for location.
Content of the invention
The purpose of the present invention solves the above-mentioned problems in the prior art exactly, provides in a kind of building-block machine processing,
The workpiece not facilitating position to positioning also can carry out the fixture supporting mechanism for location that positioning supports.
For achieving the above object, the technical solution of the present invention is：A kind of fixture supporting mechanism for location, it includes end
Face cam, bearing, spring, push rod, multiple push rod and support fixture；Bearing is fixed on the end face supporting fixture；Support solid
Have push rod in locking member accommodate reducing blind hole I and be perpendicular to blind hole I the multiple push rod receiving blind hole II intersecting with blind hole I；Push away
Bar is placed in blind hole I, has spring retainer protruding in the middle of it, and its underpart is wedge type inclined plane in the position intersected with each blind hole II,
The each push rod being placed in blind hole II has push rod receiving hole, push rod receiving hole in the position intersected with each wedge type inclined plane of push rod
Inwall have the inclined plane with wedge type inclined plane sliding contact；Spring housing on push rod, be positioned at the spring retainer of push rod protruding and
Between the retaining wall of bearing；Edge cam gap is fixed on the upper end of push rod.
The inclination angle of each wedge type inclined plane described above is between 8-11 °.Ensure that the self-locking of each wedge type inclined plane, also
It is exactly that each wedge type inclined plane self-locking, push rod can not move up and down again when push rod moves down into certain position.
Bottom surface one end of edge cam described above is high, one end is low, and minimum position has and spacer pin end face phase
The stopper slot joined；Spacer pin is fixed on the side of described bearing.The structure of edge cam and the setting of spacer pin, make the present invention
Push rod do not hold out against when being in relaxed state, spacer pin just withstands in stopper slot, it is to avoid each wedge type inclined plane of push rod is again
Hold out against, extend the service life of push rod and push rod.
Push rod described above is divided into forward and backward part；Forward part rear end is fixing screw, and the front end of rear section is screw thread
Groove, forward and backward two parts are fixed together by screw and thread groove；Described push rod receiving hole is opened in rear section.Push rod divides
For forward and backward two parts, when holding out against positioning is carried out to various sizes of workpiece, as long as changing forward part, without integral replacing
Push rod, reduces use cost.
During use, during clamping, rotating and lower pressure side face cam, push rod moves down, and each wedge type inclined plane of push rod promotes each top
The inclined plane in push rod receiving hole on bar, promotes push rod to move into place, and push rod holds out against processed workpiece, and push rod self-locking is whole
Individual device maintains static；When unclamping, lifting edge cam, rotating, push rod and push rod move up, after putting in place, and whole positioning dress
Put and unclamp.
The present invention has plural positioning mandril, can not facilitate the workpiece of position to carry out dispersiveness multiple spot to positioning
Positioning so that workpiece is effectively spacing when processing, it is ensured that the requirement on machining accuracy of part to be processed.The present invention also is adapted for commonly
The positioning of workpiece to be machined.
