Abstract
The invention relates to a sewing machine chuck which comprises a chuck body, three sliders, three clamping claws, a positioning claw and a contracting and releasing disc. Three sliding grooves are radially distributed on the chuck body, the sliders are arranged in and can slide along the sliding grooves, the clamping claws are arranged on the sliders, the positioning claw is arranged on the chuck body, the contracting and releasing disc is arranged in the chuck body and can pull the sliders to synchronously slide in a manner of being contracted towards or being away from the center of the chuck body, a guide groove is further arranged on the chuck body radially, the positioning claw is arranged in and can move along the guide groove, a fixing member capable of fixing the positioning claw at a certain position in the guide groove is arranged on a base portion of the positioning groove, adjacent intervals between two of the sliding grooves and the guide groove are smaller than 120 degrees, the other sliding groove divides the two sliding grooves equally, and an angle formed between the moving direction of the positioning claw and the sliding direction of the slider adjacent to the positioning claw is not larger than 60 degrees. The sewing machine chuck has the advantages of convenience and accuracy in adjusting and positioning, large in controllable range, wide in application range and the like.
Description
Technical field
The present invention relates to a kind of sewing machine chuck.
Background technology
Traditional, pneumatic multijaw jig mostly is synchronous extendible jig, and a plurality of claws tighten up gripping, installation or retaining element simultaneously, and it is only applicable to regular shape and fixing element, when component shape changes to some extent, just can only change applicable chuck.Chinese patent CN201357240Y discloses a kind of chuck that can pass through applicable various shape element, by adjusting the position of claw on slide block, carrys out corresponding difform element.But it is still synchronous folding and unfolding in essence, therefore each adjustment all needs to tighten up rear confirmation once, when component shape is irregular, also needs repeatedly proofread and correct and confirm.Therefore need to a kind ofly can adapt to various shapes and even erose element, be convenient to again the jig of adjusting, accurate positioning.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned defect that how to overcome prior art, and a kind of sewing machine chuck is provided.
For solving the problems of the technologies described above, this sewing machine chuck bag comprises chuck body, some slide blocks and some claws; On described chuck body, radially lay some chutes, described slide block is arranged in this chute, and can slide along chute, described claw is arranged on slide block, it also comprises the locating detent being arranged on chuck body, with be located in chuck body, and can pull slide block synchronously to receive to chuck body center or synchronously away from the folding and unfolding dish of chuck body central slide; On described chuck body, be also radially provided with a gathering sill, described locating detent is located in this gathering sill, and can move along gathering sill, and this locating detent base portion is provided with the fixture that can be fixed in a certain position in gathering sill; Described chute, slide block, claw respectively have three, and wherein two chutes and gathering sill adjacent spaces are less than 120 degree, and another chute is divided above-mentioned two chutes equally, and the slide block glide direction angulation that described locating detent moving direction is adjacent is all not more than 60 degree.
As optimization, described folding and unfolding dish is sheathed in chuck body, and can axially move along chuck body axis, and its outer end circumference is provided with T shape skewed slot; Described slip front is provided with T shape wedge, and the sliding accessory of this T shape wedge is connected in T shape skewed slot, and the formation Wedge mechanism that cooperatively interacts.
As optimization, described gathering sill below is provided with one section of cavity; Described locating detent base portion has through hole, and is furnished with fastening bolt.
As optimization, described slide block cross section is " work " font, and described chute both sides are provided with the card article of protrusion; Described claw cross section is trapezoidal, and its sliding accessory is connected on slide block, and claw is provided with the fixture that can be fixed in a certain position on slide block.
A kind of sewing machine chuck of the present invention, simple in structure, with low cost, there is the advantages such as the location of adjusting is convenient accurately, controlled range is large, applied widely, be applicable to gripping, the installation and fixing of various shape workpieces.
