Abstract

The utility model relates to a kind of spring-piece type bulging binding clasp, stepped axle excircle is connected with abutment sleeve, left shell fragment, right shell fragment, baffle plate and push pedal, left shell fragment and right shell fragment are arranged on the both sides of abutment sleeve, the end face outside of right shell fragment is fixedly connected with baffle plate, baffle plate end face outside is fixedly connected with push pedal, push pedal end face outside is provided with locking device, and locking device is fixedly connected with axle.Owing to adopting bulging positioning clamping in shell fragment, clamping, centering once complete: have positioning precision high, low cost of manufacture, and clamping is rapid, can clamping heavy parts, safe and reliable.

Description

Spring-piece type bulging binding clasp
Technical field
The utility model relates to a kind of spring-piece type bulging binding clasp, is applicable to numerically controlled lathe and the large-scale workplace needing quick-clamping workpiece with the rotary part processing excircles of location, hole of engine lathe batch turning.
Background technology
At present, the outer bowlder of numerically controlled lathe and engine lathe turning rotary part, or by three-jaw or four paws chuck centering clamping cutting workpiece, then cannot locate and clamping turning part during turning huge revolving part, this method not only the work piece clamping time long, and centering not easily.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of spring-piece type bulging binding clasp, owing to adopting bulging positioning clamping in shell fragment, there is centering precision high, convenient mounting and clamping, repeated clamping can ensure positioning precision, clamping, centering once complete, and utilize this mechanism can shorten numerically controlled lathe and engine lathe clamping time, significantly improve lathe production efficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of spring-piece type bulging binding clasp, stepped axle excircle is connected with abutment sleeve, left shell fragment, right shell fragment, baffle plate and push pedal, left shell fragment and right shell fragment are arranged on the both sides of abutment sleeve, the end face outside of right shell fragment is fixedly connected with baffle plate, baffle plate end face outside is fixedly connected with push pedal, and push pedal end face outside is provided with locking device, and locking device is fixedly connected with axle.The left shell fragment connected by axle upper surface and right shell fragment, when workpiece is placed on shell fragment, outwards stretched when shell fragment is stressed, carries out clamping locking to needing the workpiece of clamping.
Preferably, feather key is provided with between described axle and push pedal.
Preferably, described axle is provided with stepped throughhole, and shape of through holes is that diameter large mid diameter in two ends is little, is provided with internal thread in through hole.
Preferably, described abutment sleeve and axle are flexibly connected and the coincidence of the axial line of abutment sleeve and axle.
Preferably, described locking device is lock-screw.
Preferably, described left shell fragment and right shell fragment are thin-walled spherical structure, and the left shell fragment of right shell fragment number ratio many 1-2 sheet.Both sides shell fragment quantity is different, is convenient to carry out clamping to the workpiece of different-diameter.
The beneficial effect that the utility model brings is: this utility model is owing to adopting bulging positioning clamping in shell fragment, clamping, centering once complete: have positioning precision high, low cost of manufacture, clamping is rapid, can clamping heavy parts, safe and reliable, the inconvenience of particularly suitable batch heavy parts uses the workplace of three-jaw chuck location Clamp blocks, significantly can shorten numerically controlled lathe and engine lathe clamping time, significantly improve lathe production efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of spring-piece type bulging binding clasp.
Wherein, 1-lock-screw, 2-push pedal, 3-baffle plate, the right shell fragment of 4-, 5-feather key, 6-abutment sleeve, the left shell fragment of 7-, 8-axle, 9-through hole.
Detailed description of the invention
A kind of spring-piece type bulging binding clasp, stepped axle 8 excircle is connected with abutment sleeve 6, left shell fragment 7, right shell fragment 8, baffle plate 3 and push pedal 2, left shell fragment 7 and right shell fragment 8 are arranged on the both sides of abutment sleeve 6, the end face outside of right shell fragment 4 is fixedly connected with baffle plate 3, baffle plate 3 end face outside is fixedly connected with push pedal 2, push pedal 2 end face outside is provided with locking device, and locking device is fixedly connected with axle 8.The left shell fragment 7 connected by axle 8 upper surface and right shell fragment 4, when workpiece is placed on shell fragment, outwards stretched when making shell fragment stressed by locking device, carries out clamping locking to needing the workpiece of clamping.
Preferably, feather key 5 is provided with between described axle 8 and push pedal 2.
Preferably, described axle 8 is provided with stepped throughhole 9, and through hole 9 shape is that diameter large mid diameter in two ends is little, is provided with internal thread in through hole 9.
Preferably, described abutment sleeve 6 and axle 8 are flexibly connected and the coincidence of the axial line of abutment sleeve 6 and axle 8.
Preferably, described locking device is lock-screw 1.
Preferably, described left shell fragment 7 and right shell fragment 4 are thin-walled spherical structure, and the left shell fragment of right shell fragment 4 number ratio 1-2 more than 7 sheet.
The course of work:
First install by clamping workpiece, adjust the quantity of left shell fragment 7 and right shell fragment 4 according to the diameter of workpiece, sheet number many 1-2 sheet of the right shell fragment 4 of number ratio of left shell fragment 7; Secondly, lock screw 1 is tightened according to the diameter of workpiece, lock-screw 1 compresses push pedal 2, push pedal 2 promotes baffle plate 3 thus compresses right shell fragment 4, power is passed to abutment sleeve 6 by right shell fragment 4, and then compressing left shell fragment 7, left shell fragment 7 and right shell fragment 4 stretch to by the direction of clamping parts under the effect being subject to coupling mechanism force, part tensioner are located.Owing to adopting bulging positioning clamping in shell fragment, there is centering precision high, convenient mounting and clamping, repeated clamping can ensure positioning precision, clamping, centering once complete, and utilize this mechanism can shorten numerically controlled lathe and engine lathe clamping time, significantly improve lathe production efficiency.
