Description

A kind of large thin-wall cylinder section part integrally positions milling clamp
Technical field
This utility model is related to mechanical clamp field, and more particularly, to a kind of large thin-wall cylinder section part integrally positions milling folder Tool.
Background technology
Large thin-wall housing generally foundry goods, internal is network, and dimension precision requirement is high, overall Geometrical Tolerance Principle Strictly.
Due to housing this in series of process machine add during certain deformation can occur, when it is fixed on lathe On when carry out internal machine and add, the time being deformed due to its own and the factor of poor rigidity, add to enclosure interior grid Work brings difficulty;
, due to the backwardness of design and manufacturing process, often stability in the large is very poor, no for traditional lathe milling clamp The machine that method meets housing adds requirement;Need to fix it is impossible to move again on the spot after debugging;Need during use live shimming or other Adjustment block is adjusting;Product cannot be accurately positioned and be fixed, thus affecting production progress, production efficiency is relatively low.
Traditional installation way part uses column support bar clamping parts, because retaining part leads to zero for above-below direction There is the possibility of deformation in the part course of processing;And clamping cycle length requires sternly;And the part process-cycle is longer, the direction of thrust has Part deformation may be led to.
Content of the invention
The purpose of this utility model is that a kind of large thin-wall cylinder section part of offer integrally positions milling clamp, to solve The problems referred to above.
To achieve these goals, the technical solution adopted in the utility model is such:A kind of large thin-wall cylinder section zero Part integrally positions milling clamp, including pallet, described pallet is provided with several arc jacking blocks and support block, described arc jacking block Correspond with support block, described arc jacking block is located inside support block, and described support block is provided with housing screw, Shuo Gesuo State the center of circle of arc jacking block and the center superposition of described pallet.
As preferred technical scheme:Described arc jacking block is uniformly arranged.
As preferred technical scheme:Described pallet is rounded, and adopts HT250 material.
As preferred technical scheme:T-slot is provided with described pallet and mitigates groove.T-slot is easy to clamping, mitigates groove Ensure that pallet is fitted closely with platen face, decrease frock clamping error, more preferable locating effect can be played.
This utility model adopts circumferentially fixed compression mode, bump contact;Reduce the part that its internal stresses release leads to Deformation it is ensured that machine plus rear part form and position tolerance, reduce manufacture difficulty, reduce clamping alignment time;Thus improving part Production efficiency;
Adopt arc jacking block to design on tool positioning device, both ensured that contact area during parts fixation also improved simultaneously The processing rigidity of part so as to machine plus during part there is good machine additivity energy stricture of vagina be existing it is ensured that the machine added-time does not quiver As.
Compared with prior art, the utility model has the advantage of:This utility model energy precise control shell part Machining accuracy and Geometrical Tolerance Principle;Part quality can be effectively ensured, the ease of handling realizing shell part processing is effective Property, reduce operator's maloperation and the quality problems that produce improve production efficiency;
This form and position tolerance strong adaptability, operation is simple and reliable, and high accuracy zero requirement on machining accuracy can be effectively ensured during installation, Have a good application prospect, can be easily scalable in the processing of other similar housing parts.
Brief description
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the structural representation after this utility model clamping parts.
In figure:1st, pallet;2nd, support block;3rd, arc jacking block;4th, housing screw;5th, T-slot;6th, housing to be processed.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment
Referring to Fig. 1, a kind of large thin-wall cylinder section part integrally positions milling clamp, and including pallet 1, pallet 1 is integrated machine The circle of add-on type, overall dimensions Φ 2500 × 175 is, and adopts HT250 material, pallet 1 is uniformly machined with 16 T-shaped Groove 5, T-slot 5 processes along the radial direction of pallet 1, and pallet 1 is provided with eight arc jacking blocks 3 and eight support blocks 2, arc Jacking block 3 and support block 2 correspond composition and hold out against unit, and arc jacking block 3 is located inside support block 2, the circle of eight arc jacking blocks 3 The heart is overlapped with the center of circle of pallet 1, and that is, eight arc jacking blocks 3 are uniformly distributed on the circumferencial direction of pallet 1, and its adjacent line is even Rounded after connecing, support block 2 is provided with housing screw 4, housing screw 4 is contacted through support block with arc jacking block 3, support block 2 are fixedly connected with the tray, and arc jacking block 3 can moving radially along pallet 1 under the left and right of housing screw 4;
In actual clamping process, as shown in Fig. 2 housing 6 to be processed is placed on pallet 1, by adjusting housing screw 4 Mobile arc jacking block 3 makes housing 6 to be processed be fixed in frock, the cambered surface of the outer wall of housing 6 to be processed and arc jacking block 3 inner side Fitted, the mobile arc jacking block 3 of housing screw 4 is allowed to wall energy outer with housing 6 to be processed and fits as far as possible it is ensured that it is as base Standard keeps stable during ensuing machine adds, and meets product orientation required precision, and the cambered surface of arc jacking block 3 is pressed product and existed Felt is installed in theoretical size processing on outside thereon, and operator is judged with this by clearance gauge and adjusts in product and frock Installation situation, meet design requirement.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in this utility model Protection domain within.
