Abstract

The utility model relates to a part clamping cover, personally experience sth. Part of the body along the cover that the fore -and -aft direction extends including the axial, the cover body on be equipped with from the cover axon and have a plurality ofly to the terminal surface along cover body circumference equipartition towards the interval clearance that the axial other end extends, interval clearance, a plurality of interval clearances will a plurality of elasticity centre gripping arms are separated into to the cover body. The utility model provides a part centre gripping cover has a plurality of interval clearances because the cover body is gone up along the circumference equipartition when using, these interval clearances will be overlapped the body and separate into a plurality of elasticity centre gripping arms, and the interval clearance of equipartition makes elasticity centre gripping arm make the clamping cover to exert clamping effort on the internals at the even atress that makes progress in week, can guarantee effectively that the clamping cover to the clamping centering precision of part, effectively improves clamping positioning accuracy.

Description

A kind of parts fixation cover
Technical field
The utility model relates to a kind of parts fixation cover.
Background technology
At use lathe, fastening piece is carried out in the course of processing, often run into hexagonal, the fastening pieces such as 12 jiaos, during these fastening pieces of clamping, due to the problem of fastening piece periphery, the direct clamping of chuck is comparatively difficult, comparatively loaded down with trivial details in clamping process, and clamping precision and clamping efficiency are all lower.
At Authorization Notice No. be the Chinese utility model patent of CN203471373U discloses a kind of the opposite sex part jacket structured, this is jacket structured comprises chuck, chuck has the part folder hole according to different opposite sex External Shape design, the cover wall of chuck is provided with clamping groove, this kind of clamping groove is the groove structure extending to the other end along the axis of chuck from one end, and the radial direction that this kind of clamping groove presss from both sides hole along part is from the periphery of chuck from interior extension so that chuck is U-shaped. During use, the natural resiliency of U-shaped chuck is utilized to carry out elastic fixture part to be processed.
But owing to clamping groove is the axially extended groove structure along chuck in above-mentioned chuck, this makes chuck can only design U-shaped single side opening structure, the structure of chuck is also asymmetric, and part unbalance stress in the circumferential during clamping parts, can have influence on the clamping centering precision to part time serious.
Summary of the invention
The utility model provides a kind of parts fixation cover, to solve the technical problem of part chuck part stress inequality when clamping parts of the prior art.
The technical scheme of parts fixation provided by the utility model cover is: a kind of parts fixation cover, comprise the body axially extended along the longitudinal direction, described body is provided with the gap, interval extended from body axial end towards the axial the other end, gap, interval is evenly equipped with multiple along body circumference, and described body is separated into multiple elastic clip gripping arm by gap, multiple interval.
All gaps, interval all extend from the front end of body facing to rear end or all extend towards front end from the aft end face of body.
Described gap, interval comprises the space before gap extended from body front end facing to rear end and from the gap, rear interval that body aft end face extends towards front end, and gap, forward and backward interval is corresponding staggered spaced apart in body circumference.
Being convexly equipped with clamped flanges on the periphery of described body, described clamped flanges is axially run through with by its corresponding separation along body in described space before gap or rear gap, interval.
Described clamped flanges runs through separation by space before gap, and clamped flanges correspondence is arranged near the front end of described body.
The beneficial effects of the utility model are: part retaining sleeve provided by the utility model is in use, owing to body being circumferentially evenly equipped with gap, multiple interval, body is separated into multiple elastic clip gripping arm by these gaps, interval, the clamping reactive force that uniform gap, interval makes elastic clip gripping arm make mounting clip sleeve be applied on internals is evenly subject to power in the circumferential, can effectively ensure that mounting clip sleeve is to the clamping centering precision of part, effectively improve Set and Positioning precision.
Further, gap, interval is included in body circumference corresponding staggered space before gap spaced apart and gap, rear interval, gap, forward and backward interval forms elastic clip gripping arm respectively at the axial two ends of body, can improve the elastic fixture power of whole mounting clip sleeve further.
Accompanying drawing explanation
Fig. 1 is the front view of parts fixation provided by the utility model cover;
Fig. 2 is the vertical view of clamping tooling shown in Fig. 1;
Fig. 3 is the side-view of clamping tooling shown in Fig. 1.
Embodiment
As shown in Figure 1 to Figure 3, the embodiment of a kind of parts fixation cover, mounting clip sleeve in this embodiment comprises the body 1 axially extended along the longitudinal direction, body 1 has for the clamping hole 10 corresponding with treating the part periphery of clamping, body 1 is provided with the gap, interval extended from body axial end towards the axial the other end, gap, interval is evenly equipped with multiple along body circumference, and described body is separated into multiple elastic clip gripping arm by gap, multiple interval.
In the present embodiment, gap, interval comprises the space before gap 3 extended from body front end facing to rear end and corresponding staggered spaced apart in the circumference of body 1 from the gap, rear interval 5 that body aft end face extends towards front end, space before gap 3 and gap, rear interval 5. The elastic clip gripping arm that space before gap 3 is separated to form is front elastic clip gripping arm 7, and the elastic clip gripping arm that gap, rear interval 5 is separated to form is rear elastic clip gripping arm 8.
In addition, the periphery of the body 1 of the parts fixation cover that the present embodiment provides being convexly equipped with clamped flanges 4, space before gap 3 is axially run through clamped flanges 4 along body and its correspondence is separated. And the clamped flanges 4 in the present embodiment arranges near the front end of body.
During use, mounting clip sleeve Set and Positioning 12 jiaos of fastening pieces that the present embodiment provides can be used, corresponding for part is seated in clamping hole, now, the inner peripheral surface in the clamping hole 10 on body 1 corresponds to dodecagon, and the cylindrical of thread jaw chuck on lathe or clamping mounting clip sleeve corresponding to trombone slide, is tightened up by front and back elastic clip gripping arm with clamping parts in clamping process simultaneously, part stress is comparatively even, effectively ensures the centering clamping to part and not damaged.
In the present embodiment, gap, interval comprises space before gap and gap, rear interval, in other embodiments, it is possible to make all gaps, interval all extend from the front end of body facing to rear end or all extend towards front end from the aft end face of body.
In the present embodiment, clamped flanges is arranged near front end, runs through by space before gap, when clamped flanges is arranged in the middle part of body, it is possible to run through by gap, rear interval.
In the present embodiment, the inner peripheral surface in the clamping hole of mounting clip sleeve is dodecagon, and in other embodiments, when for other structures such as clamping cylindrical surface or hexahedrons, the inner peripheral surface in clamping hole can according to the actual periphery Design and Machining of part.
