Embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
See figures.1.and.2, the present embodiment three coordinate measuring machine blade grip unit J, comprise supporting seat 1, on supporting seat 1, be mounted with locating piece 2, guide rail 3, active grab holder 4 and be arranged on the active grab 5 on active grab holder, clamp 6 is installed on the sliding part of guide rail 3, locating piece 2 respectively has two osculatory with the clamping surface clamping surface of clamp 6 and the tenon root of blade 7, and the pinching end of active grab 5 is towards the rear end of clamp 6.Orientation described herein " rear end " and following orientation " front end " are that the clamp 6 clamping surface place ends of take are its front end with the clamping direction definition of clamp 6, and holding therewith relative one end is rear end.Active grab 5 is as the binding clasp of clamp 6, and during clamping, the pinching end of active grab 5 is against the application of force on the rear end of clamp 6 makes it clamp blade 7.
With reference to Fig. 3, on supporting seat 1, offer guide rails assembling groove 1-1, guide rail 3 is arranged in guide rails assembling groove 1-1.And the present embodiment middle guide 3 adopts two groups of crossed roller guide rails to be used in conjunction with, each is organized guide rail 3 and comprises moving guide rail 3-1 and quiet guide rail 3-2, and the cylindrical roller between dynamic and static guide rail, moving guide rail 3-1 is positioned at inner side, quiet guide rail 3-2 is positioned at outside, quiet guide rail 3-2 is fixed on supporting seat 1, and clamp 6 is arranged on the moving guide rail 3-2 of two groups of guide rails 3, by two moving guide rail 3-2, provides guiding.Moving guide rail 3-1 and quiet guide rail 3-2 all adopt and are bolted connection, and are convenient to quick-replaceable, to adapt to the clamping of different workpieces, highly versatile.
Adopt crossed roller guide rail, good guidance quality is provided on the one hand, the more important thing is, can be by adjusting the clearance t of quiet guide rail 3-2 and moving guide rail 3-1, realize the floating type compression of clamp 6, clearance t has been given one of the moving guide rail 3-1-clamp 6 assembly loosening space except sliding, that is to say, clearance t allows that moving guide rail 3-1-clamp 6 assemblys are fully pressed together on workpiece with form surface adaptively, to avoid blade 7 to be crossed, locate, thereby guarantee that workpiece can take locating piece 2 and locate as benchmark, guaranteed clamping precision, evidence, this floating type clamping structure specific rigidity clamps, the positional precision of workpiece can improve 2～3 orders of magnitude.
For ease of adjusting the clearance t between quiet guide rail 3-2 and moving guide rail 3-1, realize the floating type compression of clamp 6, the position of quiet guide rail 3-2 on supporting seat 1 in corresponding every group of guide rail 3 is provided with adjusts jackscrew 8, adjusts jackscrew 8 and can and contact quiet guide rail 3-2 to quiet guide rail 3-2 precession.During adjustment, unscrew the set bolt of quiet guide rail 3-2, then towards quiet guide rail 3-2 precession, adjust jackscrew 8, thereby change the size of the clearance t between quiet guide rail 3-2 and moving guide rail 3-1, or regulate and adjust jackscrew 8 round about, change the size of the clearance t between quiet guide rail 3-2 and moving guide rail 3-1.
For after blade 7 being clamped measure, clamp 6 can automatically reset by servo-actuated guide rail 3-1, improves clamping and measures efficiency, between the front end of moving guide rail 3-1 and supporting seat 1, is provided with back-moving spring 9.Particularly, at the front end that moves guide rail 3-1, bearing pin 10 is installed, one end of back-moving spring 9 is set on bearing pin 10, and bearing pin 10 can also play guiding and booster action to back-moving spring 9.
In addition, before clamping, blade must prepare attitude in standard, if blade departs from standard preparation, attitude is too much, and locating piece 2 possibly cannot play the effect of location, and blade will be by folder partially.Therefore, in the present embodiment, on supporting seat 1, the tenon root position of corresponding blade 7 is provided with axial location pin 11 and spring pin 12, adopt the snap-in force of register pin and spring pin to limit blade 7 position vertically, can avoid clamping process Leaf 7 to lose the front preparation of standard clamping attitude because rocking, as shown in Figure 2.Equally, for ferromagnetic blade, can in the hole of locating piece 2, fill ferrimagnet, for the blade of nonferromagnetic, can use stickum or pneumatic restriction, can function as described above, the present embodiment is not done concrete restriction at this.Evidence, adopt this structural design, greatly reduces and even avoided " folder partially " phenomenon of causing because of external interference in clamping process.
With reference to Fig. 4, the present embodiment has also proposed a kind of modular blade measured material, comprises pallet 13, is installed with at least one three coordinate measuring machine blade grip unit J on pallet 13.Wherein, the concrete structure of three coordinate measuring machine blade grip unit J can be referring to the embodiment of the utility model three coordinate measuring machine blade grip unit, and the description of accompanying drawing 1-3, does not repeat them here.During use, the integral installation of modular blade measured material, on the worktable of measuring machine, is positioned by the fixture positioning rule on worktable.
For ease of installing/dismounting, on pallet 13, be also provided with handle 14.
The above, it is only preferred embodiment of the present utility model, be not the utility model to be done to the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
