Abstract
The invention relates to an elastic piece type expansion clamp. The outer periphery of a stepped mandrel is connected with a positioning sleeve, a left elastic piece, a right elastic piece, a retaining plate and a push plate. The left elastic piece and the right elastic piece are disposed on two sides of the positioning sleeve. The retaining plate is fixedly connected to the outer end face of the right elastic piece. The push plate is fixedly connected to the outer end face of the retaining plate. A locking device is disposed on the outer end face of the push plate and fixedly connected with the mandrel. Due to the fact that an elastic piece inner expansion positioning clamp structure is used, clamping and centering are completed at one step. The elastic piece type expansion clamp is high in positioning precision, low in manufacturing cost, fast in clamping, capable of clamping large parts, and safe and reliable.
Description
Technical field
The present invention relates to a kind of spring-piece type bulging binding clasp, be applicable to numerically controlled lathe and the engine lathe large-scale rotary part processing excircles with location, hole of turning and need the workplace of quick-clamping workpiece in batches.
Background technology
At present, the outer bowlder of numerically controlled lathe and engine lathe turning rotary part, or clamp cutting workpiece by three-jaw or the centering of four paws chuck, when turning huge revolving part, cannot locate and clamping turning part, this method not only the work piece clamping time long, and centering be difficult for.
Summary of the invention
The technical problem to be solved in the present invention 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, can repeated clamping 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, technical scheme of the present invention 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 outside end face of right shell fragment is fixedly connected with baffle plate, outside baffle plate, end face is fixedly connected with push pedal, and end face is provided with locking device outside push pedal, and locking device is fixedly connected with axle.The left shell fragment connecting by axle upper surface and right shell fragment, when workpiece is placed on shell fragment, outwards stretch when shell fragment is stressed, and the workpiece that needs are clamped clamps locking.
Preferably, between described axle and push pedal, be provided with feather key.
Preferably, described axle is provided with stepped through hole, 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, the axial line of described abutment sleeve and axle flexible connection and abutment sleeve and axle overlaps.
Preferably, described locking device is lock-screw.
Preferably, described left shell fragment and right shell fragment are thin-walled spherical structure, and right shell fragment quantity is than left many 1-2 of shell fragment sheet.Both sides shell fragment quantity difference, is convenient to the workpiece of different-diameter to carry out clamping.
The beneficial effect that the present invention brings is: this invention 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, particularly suitable in batches heavy parts inconvenience uses three-jaw chuck location to clamp the workplace of part, can significantly shorten numerically controlled lathe and engine lathe clamping time, significantly improve lathe production efficiency.
Brief description of the drawings
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 excircles are 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 outside end face of right shell fragment 4 is fixedly connected with baffle plate 3, baffle plate 3 outside end faces are fixedly connected with push pedal 2, push pedal 2 outside end faces are provided with locking device, and locking device is fixedly connected with axle 8.The left shell fragment 7 and the right shell fragment 4 that connect by axle 8 upper surfaces, when workpiece is placed on shell fragment, outwards stretch while making shell fragment stressed by locking device, and the workpiece that needs are clamped clamps locking.
Preferably, between described axle 8 and push pedal 2, be provided with feather key 5.
Preferably, described axle 8 is provided with stepped through hole 9, and it is little that through hole 9 is shaped as the large mid diameter of two ends diameter, in through hole 9, is provided with internal thread.
Preferably, described abutment sleeve 6 and axle 8 are flexibly connected and the axial line of abutment sleeve 6 and axle 8 overlaps.
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 right shell fragment 4 quantity are than left shell fragment 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, the quantity of left shell fragment 7 is than many 1-2 of sheet number sheet of right shell fragment 4; Secondly, tighten lock screw 1 according to the diameter of workpiece, lock-screw 1 compresses push pedal 2, thereby push pedal 2 promotes baffle plate 3 and 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 to being stretched by the direction of clamping parts, are located part tensioner under the effect that is subject to coupling mechanism force.Owing to adopting bulging positioning clamping in shell fragment, there is centering precision high, convenient mounting and clamping, can repeated clamping 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.
