Abstract
The invention relates to a positioning and clamping device for an annular surface. The positioning and clamping device for the annular surface comprises a double-headed threaded shaft, positioning hinge pins, a left-hand thread sleeve, a positioning shaft and a right-hand thread sleeve, wherein the axis of the double-headed threaded shaft coincides with the axis of the positioning shaft; left-hand threads and right-hand threads at two ends of the double-headed threaded shaft are respectively screwed with the left-hand thread sleeve and the right-hand thread sleeve correspondingly; the positioning hinge pins are positioned in through holes formed in the positioning shaft; one end of each positioning hinge pin is an inclined plane which is matched with a conical surface of the left-hand thread sleeve or a conical surface of the right-hand thread sleeve; the other end of the positioning hinge pins is provided with a split washer; and by the split washer, the positioning hinge pins are prevented from slipping out from the through holes of the positioning shaft and are withdrawn. The double-headed threaded shaft is matched with the through the double-headed threaded shaft, the positioning precision is high, positioning is reliable, and the universality is high.
Description
Technical field
The present invention relates to musical instrument processing technique field, particularly a kind of positioning clamping device of ring surface.
Background technology
Percussion instrument is also named " percussion instrument ", refers to pulsatile body and a kind musical instrument of sounding.If the sounding body different according to percussion instrument is distinguished, two classes can be divided into: (1) " leather crying musical instrument " is also named " film crying musical instrument ", exactly by beaing the epithelium covered on musical instrument or the musical instrument of removing from office film and sounding, as various drum-type instrument; (2) " body crying musical instrument " is exactly sounding by pulsatile body, as clock, wooden fish, various gong, cymbals, bell etc.
Adding man-hour to various drum-type instrument, the ring surface of drum-type instrument is not easily processed because shape is curved surface.To in the process of planar annular, lathe can be subject to the effect of cutting force, centrifugal force, inertia force etc.; For ensureing under these External Force Actings, lathe still can keep by the determined Working position of setting element, and processing steadily, and ensure precision, unlikely generation vibration and displacement, must make workpiece locate reliably and clamping relative to lathe.
Summary of the invention
The object of the invention is to, provide a kind of location for the deficiencies in the prior art and clamp ring surface, thus ensure that machine tooling is steady, improve the positioning clamping device of working (machining) efficiency.
To achieve these goals, the technical solution adopted in the present invention is as follows: a kind of positioning clamping device of ring surface, comprising: double thread axle, alignment pin, left hand thread cover, locating shaft, right-handed thread cover; The axis coinciding of double thread axle and locating shaft; The left hand thread at the both ends of double thread axle and right-handed thread, overlap with corresponding left hand thread respectively and right-handed thread cover screws; Alignment pin is arranged in the through hole that locating shaft is opened, and one end of alignment pin is inclined-plane, and the other end is provided with split washer; Split washer prevents alignment pin from skidding off from the through hole of locating shaft and regaining alignment pin.
Described locating shaft is hollow shaft, and centre can be inserted guide rod and is connected with double thread axle, and carries out the rotation process of double thread axle by guide rod, completes clamping.
Described left hand thread cover and the end, one end of right-handed thread cover are all taper seats.
Beneficial effect of the present invention is, this positioning clamping device by double thread axle and alignment pin with the use of, have that positioning precision is high, location reliably, the advantage of highly versatile.
Accompanying drawing explanation
Fig. 1 is the positioning clamping device structural representation of this ring surface.
Above-mentioned number in the figure is described as follows:
1---double thread axle; 2---alignment pin; 3---left hand thread cover; 4---locating shaft; 5---right-handed thread cover; 6---split washer.
Detailed description of the invention
Technical scheme of the present invention is described further by specific embodiment below in conjunction with accompanying drawing.
A positioning clamping device for ring surface, comprising: double thread axle 1, alignment pin 2, left hand thread cover 3, locating shaft 4, right-handed thread cover 5; The axis coinciding of double thread axle 1 and locating shaft 4; The both ends of double thread axle 1 have left hand thread and right-handed thread respectively, its overlap with corresponding left hand thread respectively 3 and right-handed thread overlap 5 and screw; Alignment pin 2 is arranged in the through hole that locating shaft 4 is opened, one end of alignment pin 2 be overlap 3 with left hand thread, inclined-plane that taper seat that right-handed thread overlaps 5 matches, the other end is provided with split washer 6; Split washer 6 prevents alignment pin 2 from skidding off from the through hole of locating shaft 4 and regaining alignment pin 2.
Operation principle is as follows: the left hand thread of double thread axle 1 end and right-handed thread, with left hand thread overlap 3 and right-handed thread overlap 5 and screw, turn double thread axle 1, left-handed, right-handed thread cover will produce displacement to centre, the taper seat of thread bush end ejects alignment pin 2, finally withstands clamping work pieces.
Claims (3)
