Abstract
A flexible arm clamp for grinding a window of a car transmission shaft retainer comprises: the right supporting arm is provided with an upper compression screw 1, a right spring piece 2, a lower compression screw 3 and a clamping block 4 to form a right flexible arm 12. The upper compression screw 9 of the left support arm, the left spring leaf 8, the lower compression screw 7 and the left clamping block 6 form a left flexible arm 13. It is characterized in that: the combined spring leaf is formed by arranging and superposing the spring leaves with different lengths in an increasing mode, so that the design reliability of the left spring leaf 8, the right spring leaf 2 and the spring leaf A, B is increased, and the C, D has good elastic deformation. Therefore, the situation that when a single spring piece is designed originally, the spring piece is broken or generates plastic deformation when hundreds of pieces are dried, so that the situation that the workpiece 5 cannot be clamped tightly is generated or the grinding wheel is damaged is avoided.
Description
Technical field
The utility model relates to machining equipment in the workpiece processing, by the Flexible Fixturing device that the cluster spring sheet constitutes, is particularly suitable for the workpiece binding clasp of car transmission shaft retainer mill window, is applicable to self-feeding.
Background technology
The elastic arm of existing car transmission shaft retainer mill window is that 1.2～2.5 single-leaf spring sheet is formed elastic arm by thickness.Adopt this structure, when the spring leaf quenching hardness HRc54 left and right sides, easily fracture,, easily produce plastic deformation again, cause binding clasp to grab incessantly workpiece at reed drive end root when reed quenching hardness during in the HRc45 left and right sides at spring leaf drive end root.So that break up expensive emery wheel, cause unstable product quality.
Summary of the invention
The purpose of this utility model is to provide a kind of positioning accuracy height, good springiness, long service life, the Flexible Fixturing supporting arm of constant product quality (abbreviation flexible arm), thereby thoroughly solve the easily broken and spring leaf of original spring leaf and easily produce plastic deformation, can't clip workpiece, cause the accident that emery wheel smashes.Not only saved expensive emery wheel consumption, and improved positioning accuracy, reduced production cost, the new flexible arm life-span is the hundreds of times of former design flexibility arm.
Flexible arm of the present utility model is realized by following technical scheme: its special character is with one group of different length by screw 1, the spring leaf 2 of different-thickness or equal thickness is connected with actuating arm 11, by screw 3 spring leaf 2 and clamp 4 are linked together again and form right flexible arm 12, and left flexible arm be by screw 9 with one group of different length, the spring leaf 8 of different-thickness or equal thickness is connected with actuating arm 10 by screw 7 spring leaf 8 and clamp 6 to be linked together again forms left flexible arm 13.
The advantage applies of the utility model flexible arm binding clasp exists:
1. this flexible arm binding clasp, changing each a slice spring leaf of former design 1.2～2.5mm both sides is that the not isometric spring leaf of each multi-disc of both sides is formed, and the single-sheet thickness attenuate, and cumulative thickness increases, and total drag increases, and the elastic deformation amount increases.
2. solved about former spring leaf quenching hardness HRc54, produced per about 400 and promptly fracture, the average hundreds of spare of producing promptly produces plastic deformation when about quenching hardness HRc45, all has short defect in service life.
3. owing to adopt the increasing or decreasing stack by a certain percentage of spring leaf length to form flexible arm, improved the elastic deformation amount effectively, and the uniformity of strain.The spring leaf root bending distortion of the binding clasp that constitutes by the single-leaf spring sheet or the hidden danger that fractures have been eliminated.
Accompanying drawing
Fig. 1 is a flexible arm binding clasp front view.
Fig. 2 is the C-C vertical view of Fig. 1.
Fig. 3 is the side view of Fig. 1.
The specific embodiment
Utilize drawings and Examples below, the utility model is further described.
With reference to Fig. 1～3 flexible arm binding clasps, by left flexible arm 13 and driving supporting 10 and clamp 6, and right flexible arm 12 and driving supporting 11 and clamp 4 compositions.
When using the Flexible Fixturing device, promote by the lathe oil sector, drive left side supporting 10 and right supporting 11, drive left flexible arm 13 and clamp 6, promote the right supporting 11 that drives simultaneously, drive right flexible arm 12 and right clamp 4, workpiece is clamped, finish clamping action and realize feeding work, unclamp clamp 4 and clamp 6 by oil sector after, carry out the window reconditioning by other mechanism's clamping work pieces.
Claims (2)
1. flexible arm binding clasp is characterized in that it comprises by right cluster spring sheet 2 and constitutes the right flexible arm 12 of binding clasp and constitute binding clasp left side flexible arm 13 by left cluster spring sheet 8.
2. according to the described flexible arm binding clasp of claim 1, it is characterized in that and to form by the spring leaf stack of two unequal lengths; Also can increase progressively and form by multi-disc length; Can form by the uniform thickness spring leaf; Also can form by uniform thickness spring leaf not.
