Description
Technical field
The utility model belongs to machining equipment technical field, relates to the axial precision positioner of a kind of collet.
Background technology
The numerically controlled lathe of instrument lathe, processing finding and float cutter lathe etc., what these lathe holding parts generally used is all collet, and collet has the advantages such as radial location precision is high, structure is simple, with low cost, volume is little, clamping speed is fast.
But the variable quantity of the axial location relative main of self is relevant with the diameter of part after adopting collet Clamp blocks.Such as tapering is the collet of 30 °, and the variable quantity of axial location relative main is 1.9 times of diameter variable quantity, and it is larger that tapering is less than collet axial variable quantity when same diameter variable quantity of 30 °.Therefore only utilize the end face of collet itself or stepped hole to position part, the workpiece that precision is higher just can not ensure.In order to improve axial location precision, also have in prior art and put in a stock from main shaft rear portion by the hole in the middle of pull bar and position, this structure is not only complicated and rigidity is not enough, while positioning precision not high yet.
Utility model content
Main purpose of the present utility model is to provide the axial precision positioner of a kind of collet, solves the defect that existing collet axial positioning structure is complicated, rigidity is not enough and positioning precision is not high.
In order to complete technical problem to be solved in the utility model, the technical scheme that the utility model adopts is, the axial precision positioner of a kind of collet, include snap ring, inner edge along snap ring is provided with some banking stops or limit rib, and the notch of the number of banking stop or limit rib and shape and collet adapts.
Feature of the present utility model is also, banking stop or limit rib have ledge structure, and the ledge structure on all banking stops or limit rib forms a step surface.
The junction, center of limit rib is recessed to the inside.
The pipe extending to the inside and pass through for part backing-out punch is connected with between banking stop.
The beneficial effects of the utility model are:
The axial precision positioner of collet of the present utility model is relative to only utilizing the end face of collet itself or stepped hole in prior art and positioning by putting in a stock from main shaft rear portion by the hole in the middle of pull bar, not only structure is simple, intensity is high, to locate very accurate simultaneously, efficiently solves the technological deficiency of collet axial location difference.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of collet axial precision positioner, and include snap ring 1, the inner edge along snap ring 1 is provided with some banking stops 2 or limit rib 3, and the notch of the number of banking stop 2 or limit rib 3 and shape and collet adapts.
During concrete enforcement, the utility model is described for the collet of three lobe clamps (namely having three notches).
Embodiment 1: as shown in Figure 1, snap ring 1 inner edge is evenly provided with three lobe banking stops 2, banking stop 2 is right-angled trapezium, the hypotenuse of banking stop 2 is connected to snap ring 1 inner edge, right-angle side towards snap ring 1 center and with the axis parallel of snap ring 1, snap ring 1 outer rim is provided with bolt mounting holes and adopts screw to install, and this version is applicable to positioning Step Shaft workpiece, makes locating surface during location with workpiece step.
Embodiment 2: snap ring 1 inner edge is evenly provided with three lobe banking stops 2, banking stop 2 has ledge structure with the contact site of workpiece, three ledge structures form a locating surface, snap ring 1 outer rim is provided with bolt mounting holes equally and adopts screw to install, this version is applicable to position common workpiece, during location with workpiece end face as locating surface.
Embodiment 3: snap ring 1 inner edge is provided with three limit ribs 3 that center interconnects, the limit rib 3 linked together is adopted to improve structural strength, article three, limit rib 3 can setting table stage structure, the ledge structure linked together forms locating surface, article three, the junction, center of limit rib 3 to the inside recessed with reduce and instrument contact area thus raising positioning precision, snap ring 1 outer rim is provided with bolt mounting holes and adopts screw to install, this version is applicable to position common workpiece, during location with workpiece end face as locating surface.
Embodiment 4: snap ring 1 inner edge is provided with three lobe limit ribs 3, limit rib 3 has ledge structure with the contact site of workpiece, three ledge structures form a locating surface, be connected with the pipe 4 extending to the inside and pass through for part backing-out punch between limit rib 3, the locating surface that the end face of pipe 4 is formed relative to three ledge structures is slightly more rearward to reduce and the contact area of instrument thus raising positioning precision.Snap ring 1 outer rim is step, adopts pressure ring 5 to press-fit and is connected with front terminal pad.
During installation, front terminal pad 6 first loads onto collet 7, then the snap ring 1 of the utility model locator 8 is enclosed within the outer rim of collet 7, banking stop 2 or limit rib 3 insert along the notch of collet 7 and make locator 8 be arranged on the front end of collet 7, collet 7 notch than banking stop 2 or limit rib 3 slightly wider, be advisable not hinder collet 7 clamping work pieces.For locator in embodiment 1-3 8, as shown in Figure 5, directly adopt screw 9 to be fixed on by snap ring 1 on front terminal pad 6, for the locator 8 in embodiment 4, as shown in Figure 6, adopt pressure ring 5 cover to be pressed on snap ring 1 and carry out fastening with screw 9 again.During dress workpiece, collet 7 is unclamped and rear workpiece to be loaded, the locating surface of workpiece leans against on the locating surface of banking stop 2 or limit rib 3, then collet 7 is clamped, during clamping, collet 7 pairs of workpiece have a pulling force backward, workpiece by the banking stop 2 of locator 8 or limit rib 3 withstand make its cannot after move thus realize axial location.The active force backward applied due to the collet 7 pairs of workpiece is very large, and therefore the banking stop 2 of locator 8 and limit rib 3 need certain intensity.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model; above-mentioned embodiment and description are principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by claims and equivalent thereof.
