Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
Accompanying drawing 1-5 is the multi-station clamp of the present invention for micro part processing, comprising pedestal 1, is arranged on 1 time can be placed in platen 8 in T-slot T-shaped piece 4 of pedestal, connection pedestal 1 and T-shaped piece 4 of fixing bolt 5, set The upper end of pedestal 1 is arranged in the upper end of pedestal 1 and 16, two groups of groove through both sides and is spaced apart along the length direction of groove 16 Clamping station group;Clamping station group described in every group includes being arranged on the both sides of groove 16 and dress corresponding with micro part shape Press from both sides station 11;In the groove 16 retaining mechanism is provided between every assembling folder station group;The retaining mechanism includes two Deformation block 6 that block can be offset to corresponding clamping station 11, it is arranged between two pieces of deformation blocks 6 by clamping screw 3 and the spiral shell of pedestal 1 The briquetting 2 of line connection;The section of the briquetting 2 in wide at the top and narrow at the bottom trapezoidal, deformation block 6 be provided with coordinate with briquetting 2 it is oblique Face.
Further, the two bottom sides of the groove 16 are respectively arranged with the strip grooves 15 placed vertically;The deformation block 6 wraps Include be vertically arranged in strip grooves 15 and flexure strip 62 that lower end be connected with the bottom of strip grooves 15, be arranged on it is in groove 16 and elastic The latch segment 61 of the upper end of piece 62 connection, can make the Rapid reset of latch segment 61 by flexure strip 62, be easily installed workpiece 7.
Further, the latch segment 61, flexure strip 62 and pedestal 1 not only reduce fixture to be integrally formed by wire cutting Cost, and be easy to control the gap between latch segment and workpiece, and be slightly distorted with regard to workpiece can be pushed down, so as to which precision is higher, tear open Dress is convenient.
Further, the upper center of the pedestal 1 is provided with square groove 12;The bottom of the square groove 12 is provided with through hole 13; The fixing bolt 5 is threadedly coupled through through hole 13 with T-shaped piece 4, is easy to elastic fixing bolt 5, adjusts the position of pedestal 1, and Because square groove is arranged on the upper center of pedestal so that evenly, fixation is more firm for the stress of pedestal 1.
Further, clamping station group is symmetrically arranged at the both sides of square groove 12 described in two groups so that clamp structure is more Compact, weight is smaller, wherein unlimited two groups of clamping station group, can also set four groups, six groups etc., and the side of being symmetrically arranged at The both sides of groove 12, this belongs to the protection domain of this programme.
Further, the both sides of the pedestal 1 are also respectively provided with fixing groove 14, are easy to further fix by Machine tool pressure plate Pedestal 1, prevent pedestal 1 from shifting in process, influence machining accuracy.
During work:1st, T-shaped piece 4 is placed in the T-slot of platen 8, it is by fixing bolt 5 that pedestal 1 is tentatively solid It is scheduled on platen 8, the fixing groove 14 of the both sides of pedestal 1 can also be being pushed down using pressing plate, further fixed pedestal 1, made It is more firm to fix;
2nd, beat table centering pedestal 1 and finally fix, pedestal 1 is met machine tooling requirement, according to the shape and knot of workpiece 7 Structure processes corresponding clamping station 11 respectively, can reduce the resetting error of fixture, improves machining accuracy;
3rd, four workpiece 7 are placed in clamping station 11 respectively (three sides of clamping station 11 and bottom surface respectively with work Part 7 is bonded, so as to which clamping is reliable, accurate positioning), screw two clamping screws 3 respectively using spanner, move downward briquetting 2, The deformation block 6 for oppressing both sides deforms (being offset towards clamping station 11) to both sides respectively, by the clamping sides workpiece 7 of deformation block 6, So that workpiece 7 is individually fixed in clamping station 11;
4th, start to process four workpiece 7 successively;
5th, two clamping screws 3 are unscrewed, briquetting 2 is no longer oppressed deformation block 6, take out four finished works 7;
6th, repeat the above steps 3-5, until batch is completed all workpiece 7 and processed.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art:
It is of the present invention for micro part processing multi-station clamp once can the multiple micro parts of clamping, and Fast assembling and disassembling, positioning precision are high, so as to improve operating efficiency and crudy, reduce production cost and percent defective.
It the above is only the concrete application example of the present invention, protection scope of the present invention be not limited in any way.All uses Equivalent transformation or equivalent replacement and the technical scheme formed, all fall within rights protection scope of the present invention.
