Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
And accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.It should be noted that described reality
It is only a part of embodiment of the invention to apply example, rather than whole embodiments.Based on the embodiment in the present invention, this area is general
The every other embodiment that logical technical staff is obtained under the premise of creative work is not made, belongs to present invention protection
Scope.
Embodiment
Fig. 1 and Fig. 2 is referred to, present embodiment discloses a kind of active positioning block fixture, for clamping workpiece to be added, including
Localization tool 1, longitudinal clamp system and horizontal clamping mechanism；The top end opening of the localization tool 1 and formed receiving it is described to be added
The receiving portion of workpiece, longitudinal clamp system clamps workpiece to be added in vertical direction, and the horizontal clamping mechanism includes difference
The first clamping element 4 and the second clamping element 2 on two relative side walls of described accommodation section, first clamping element 4 are provided with
Along the chuck that the direction of the second clamping element 2 is stretched, second clamping element 2 can be rotatably secured to the receiving along longitudinal axis
On the internal face in portion, by second clamping element 2 along the rotation of longitudinal axis, can be formed and be transported with the chuck of first clamping element 4
Dynamic direction is in the stress surface of angle adapting to the clamping demand of given shape workpiece to be added.
General CNC vice clamps are all more single clamping structures, are applied by a fixed fixed pincers and one
The dynamic pincers composition of pressure, but the end face of product is a section, on business the reason such as poor surface quality may be caused to decline, and is caused
Two end faces to clamping are not parallel.Fixed fixed pincers no doubt do not adapt to this change, it is possible to cause clamping
The situation that unbalance stress, clamping face do not compress, unnecessary vibration will be produced in process because of without compressing, and gone out
Now shake knife mark, influences crudy.
The present invention is used second clamping element 2 that can be swung with activity and instead of the clamping effect for determining pincers.When
When pressure is stretched on the top of one clamping element 4, the chuck of its telescopic action is pressed on the end face of product, and the second clamping element of opposite side
2 just can carry out swing self adaptation according to the actual depth of parallelism of product end surface, it is ensured that compress conscientiously, have weight to the stability of clamping
Act on.In order to improve the anti-skidding effect of the second clamping element 2, and the pressure of contact is improved, the surface of second clamping element 2 is excellent
Choosing is provided with anti-skidding reticulate pattern.And simultaneously in order to coordinate swinging for the second clamping element 2, its two sides fillet is set.Meanwhile, longitudinal direction
Clamp system carries out spacing clamping to product in vertical direction, and product is just clamped firmly, is not in that the unstable influence of clamping adds
The situation of working medium amount.
Preferably, the top surface of the localization tool 1 is provided with the locating flange 3 for raising up.In fact, on geometric angle
Say, point location specific surface is positioned with more preferable positioning action, it is to avoid because machining tolerance causes actual location error occur.Convex
Face positioning is changed into point location by edge 3.
In addition, at each locating flange 3, it is also a kind of effective technology side for improving clamping stability to set clamping point
Case, as further preferably, longitudinal clamp system includes longitudinal clamping cylinder 5, connecting rod 6 and fixture block 7；Longitudinal direction clamps
Cylinder 5 is longitudinally disposed；One end of connecting rod 6 is hinged with localization tool 1, and the other end is hinged with the middle part of fixture block 7；The fixture block
7 include a clamping section 10 being engaged with locating flange 3, and a swing arm 11 extended at the rear of clamping section 10, fixture block 7
The end of swing arm 11 be hinged with the piston rod of longitudinal clamping cylinder 5, clamping section 10 and the locating flange 3 of fixture block 7 cooperatively form one
Individual flat clamping.
When longitudinal clamping cylinder 5 upwards top stretch when, will by lever principle drive fixture block 7 swing, make clamping section 10 with
Locating flange 3 is mutually closed to form clamping action.Conversely, longitudinal clamping cylinder 5 shrinks, the clamping section 10 of fixture block 7 will unclamp.
According to geometrically 3 points of principles for determining a plane, positioned in order to more efficient, reduced all parts because manufacturing tolerance is produced
Influence, preferably longitudinal clamping cylinder 5 is provided with three as further, is distributed along Atria summit sets respectively
In the both sides of localization tool 1.Three positioning action points are so in one plane generated to workpiece to be processed, it can be ensured that treat
Processing workpiece maintains the clamped condition of stabilization during processing.
As further preferably, above-mentioned active positioning block fixture also includes a positioner 8, the positioner 8
Transversely it is installed on localization tool 1, it is provided with towards setting orthogonal with the direction of first clamping element 4, and its front end
The telescopic positioning pressure head 9 that one profile is engaged with product surface.
Positioner 8 is preferably a cylinder for small stroke, and its Main Function is to carry out precisely at the initial stage placed in product
Positioning.When product is placed to the surface of localization tool 1, positioner 8 is first acted, and drives the surface of positioning pressure head 9 and product
Contact, imitates out the accurate adjustment action of staff, and a positioning is provided on the direction orthogonal with the second clamping element 2.Then side
Clamp system is acted, and the end face to product is positioned, and this process overcomes the uneven defect of section by the second clamping element 2.
It is last to carry out clamping locking vertically by longitudinal clamp system again.
A kind of active positioning block fixture provided by the present invention, by the second clamping element 2 that can be swung, for product
When end face is not parallel, can reach and more preferably compress locating effect with product end surface laminating correcting plane, compensate for end face because cut-out adds
It is not parallel that work is caused.Each clamp system carries out clamping action using cylinder, and high degree of automation is improved after accurate positioning
Production efficiency.Steadily firmly, the damage to product surface is small for fixture clamping, it is to avoid in causing process because of clamping shakiness
Unnecessary vibration, effectively improves crudy.
Embodiment described above only expresses one embodiment of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Shield scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
