Peripheral milling Double Tops point clamping tooling
Ensure the frock of ceramic insertion core axiality the present invention relates to ceramic insertion core processing unit (plant), more particularly to during processing.
The Finial device of the coaxial processing of optical fiber ceramic lock pin is typically using filling planker come real at present in miniature line slideway
Existing top movement, and it is top from a distance from guide rail typically in 50 millimeters（This includes the thickness of planker and the height of dead head
Degree）, because line slideway has gap, it can produce and rock in planker slipping, and it is top because of distance guide rail 50 on planker
Millimeter will amplify gap, so that top rock increasing, cause the product axiality of processing to become big.It is therefore desirable to design one
Kind reduces the top device rocked, so as to improve the axiality of optical fiber ceramic lock pin.
The content of the invention
The technical problems to be solved by the invention are to overcome the above-mentioned deficiency of prior art and provide a kind of peripheral milling Double Tops
Sharp clamping tooling, when the frock is used for into ceramic insertion core cylindrical lapping, reduce the top axiality rocked, ensure ceramic insertion core.
Technical scheme is used by the present invention solves the above problems：Peripheral milling Double Tops point clamping tooling includes left and right two
Base, left and right two top, top drive mechanisms, compact heap, pressing devices, two top coaxial and tops are relative, left top
Be fixed on left base, be provided with guide groove on right base or in compact heap, it is right it is top is located at guide groove, compact heap can contact right top
Point, top drive mechanism drive the right side is top to be moved along guide groove, and pressing device driving compact heap jam-packed or release are right top.
Preferable top drive mechanism holds out against the right top afterbody of ejecting rod of cylinder connection of cylinder to hold out against cylinder.
The further improved cylinder that holds out against carries air pressure regulator.
Preferable pressing device includes compression cylinder, rocking arm, compression cylinder drive cylinder connecting rod, one end hinge of rocking arm in
Air cylinder connecting rod, with cam and hinge in right base, air cylinder connecting rod moves up and down band moving cam and rotated the other end, squeezes during rotation
Pressure or the compact heap for unclamping lower section.
The design of one of which guide groove, compact heap：Fixed guide block on right base, guiding is provided with guide pad
Groove, guide groove is with left top equidirectional, and the right side is top to be located at guide groove, and right top top fastens compact heap, and the bottom surface of compact heap is opened
There is a deep-slotted chip breaker, after fastening, gap be present between the bottom surface of compact heap and guide pad.
Another design of guide groove, compact heap：Being provided among compact heap accommodates right top circular hole, circular hole bottom
As guide groove, circular hole side is provided with breach, is locked after compact heap stress right top in circular hole in portion.
Compared with prior art, the advantage of the invention is that：1st, one of them top shifting is driven using top drive mechanism
Dynamic, moving direction relies on guide groove, is both easy to load and unload the ceramic insertion core on station, decreases and rock gap；Filled using compressing
Put top by the compact heap jam-packed right side, positioned by compact heap, guide groove right top, ensure that ceramic insertion core is coaxial in process
Degree.2nd, cylinder is all used in top drive mechanism, pressing device, because driving force caused by cylinder is relatively soft, avoid because with
Power is too quickly and damages top.3rd, cylinder carries air pressure regulator, can be according to the driving force of use environment condition cylinder.4th, using band
The rocking arm of cam squeezes, compact heap, guide groove etc. are simple in construction, and manufacturing cost is low.

Below in conjunction with the accompanying drawings, the present invention is further described for embodiment.
Peripheral milling Double Tops point clamping tooling as shown in Fig. 1, including left base 1, left top 2, right base 3, it is right top 4,
Compact heap 5, hold out against cylinder 6, air pressure regulator 7, rocking arm 8, compression cylinder 9, guide pad 10.
The left position of base 1 is fixed, a fixed left side top 2 on left base 1.The position of right base 3 is fixed, device on left base 3
The right side top 4, the top top in left and right two are relative and coaxial.
The device mode on the right side top 4 is as shown in Figure 1 and Figure 2：Fixed guide block 10 on right base 3, it is provided with guide pad 10 and leads
To groove, for guide groove with left top equidirectional, the right side top 4 is located at guide groove, and right top 4 top fastens compact heap 5, compact heap 5
Bottom surface is provided with deep-slotted chip breaker, after fastening, gap be present between the bottom surface of compact heap 5 and guide pad 10, as shown in Figure 3.On right base 3
Fixation holds out against cylinder 6, and the ejecting rod of cylinder 61 for holding out against cylinder 6 is fixedly connected with the afterbody on the right side top 4, so, holds out against cylinder 6 and passes through gas
Cylinder push rod 61 drives the right side top 4 to be moved left and right along guide groove.Also be fixed and clamped cylinder 9 on right base 3, and compression cylinder 9 can drive
Air cylinder connecting rod 91 is moved up and down, and one end hinge of rocking arm 8 with cam 81 and is cut with scissors in air cylinder connecting rod 91, the other end of rocking arm 8
Chain is located at the top of compact heap 5 in right base 3, cam 81.Air cylinder connecting rod 91 moves up and down band moving cam 81 and rotated, and cam 81 revolves
Extruding or the compact heap 5 of lower section is unclamped during turning, compact heap 5, which compresses the right side top 4, during jam-packed fixes it.
In order to adjust the thrust for holding out against cylinder 6, device air pressure regulator 7 on cylinder 6 is held out against.
Equally, also can device air pressure regulator in compression cylinder 9 in order to adjust the thrust of compression cylinder 9.
Also compact heap 5 as shown in Figure 4 can be used, being provided with for the centre of compact heap 5 accommodates right top circular hole, circular hole bottom
As guide groove, circular hole side is provided with breach, after the stress of compact heap 5, locks right top in circular hole.
The use process of the frock：Start compression cylinder 9, cam 81 is unclamped compact heap by air cylinder connecting rod 91, rocking arm 8
5, unclamp the right side top 4；Startup holds out against cylinder 6, drives the right side top 4 to be retracted along guide groove by ejecting rod of cylinder 61；Pass through manipulator
Or manually by ceramic insertion core be sent into left and right it is top between；Restart and hold out against cylinder 6, the right side top 4 is stretched out along guide groove, left and right top
Point clamps ceramic insertion core；Restart compression cylinder 9, cam 81 is extruded compact heap 5, make the jam-packed of compact heap 5 right side top 4, right top
Sharp 4 positions are fixed；Start other processing unit (plant)s, processing ceramic lock pin；After machining, startup compression cylinder 9 is unclamped right top
4；Startup holds out against cylinder 6 and retracted, and ceramic insertion core departs from frock, Posterior circle this process.
