The application is that denomination of invention is: " a kind of polishing clamp for capsule mold ", application number are: 201110162333.0, the applying date is: the dividing an application of the patent application case of 2011.06.16.
Technical field
The present invention relates to a kind of polishing clamp for capsule mold, particularly a kind of lower fixture disc limiting mechanism of polishing clamp for capsule mold.
Background technology
Capsule is one of the most ancient formulation of medicine, originates from ancient Egypt, and shared ratio is about 1/3rd in the middle of all formulations of pharmaceuticals industry, so the Capsules that capsule uses is one of important packaging material of pharmaceuticals industry.
Capsule die is very important parts in the capsule manufacture, generally made by stainless steel, it is high especially that fineness requires, if use and take care of in the process because of carelessness, is easy to reel, die surface will be destroyed, destruction acquires a certain degree, and the capsule surface slippery brightness of producing will be influenced, and is serious if mould destroys again, the capsule of producing probably broken hole will occur, has a strong impact on capsule quality.
In the capsule manufacture process, reeling of capsule die is unavoidable, use a stage after, the surface of mould has the slight scratch of part, if continue long-time the use, the slight scratch of mould will strengthen, and will affect to capsule quality.Therefore for keeping capsule die fineness, general Capsules manufacturing enterprise all attaches great importance to the maintaining of mould, can regularly carry out polishing to eliminate the slight scratch of die surface to capsule die.
The capital equipment of capsule die polishing is vibratory finishing machine, a certain amount of polish abrasive---the special cermacis particle of packing in the polishing machine, add again an amount of brightener, capsule die is put into polishing machine open the polishing machine polishing regular hour, take out mould, clean up and namely finish the mold polish process, the mould light after the polishing as new.
The problem that the above-mentioned practice exists is: mould polishes the effect that can reach desirable one by one one by one, but inefficiency, through testing 80 minutes best results of each polishing time, can well imagine that 2400 moulds of every production line need the time how long? therefore to polish one by one be infeasible to the wall scroll mould, if but many moulds are put in the polishing machine, not spacing to its relative position, each mould will collide mutually, thereby produce new scratch, obviously this problem does not solve, and has just lost the meaning of polishing.
The inventor is through autonomous Design, developed a kind of be used to plugging, the polishing clamp of assemble capsule mould, these anchor clamps are comprised of the clamping apparatus disk of an anchor clamps main shaft and two circles, clamping apparatus disk is fixed on the up and down two ends of anchor clamps main shaft, the edge circumferentially is distributed with a plurality of mould slots on clamping apparatus disk, these anchor clamps once can clamp tens of capsule dies, carry out spacing to the chuck body two ends again, just can put into polishing machine these capsule anchor clamps are carried out polishing operation, can prevent the mutual collision between the mould, greatly improve the polishing efficiency of mould, reached desirable effect.Therefore also need to carry out spacingly in two ends up and down to anchor clamps, expose at two ends up and down from anchor clamps to prevent mould.
Summary of the invention
The present invention has mainly overcome the deficiencies in the prior art, and providing a kind of can carry out spacing position-limit mechanism to the lower fixture disc of polishing clamp.
Technical scheme of the present invention is achieved in that
A kind of lower fixture disc limiting mechanism of polishing clamp for capsule mold, comprise the anchor clamps main shaft, respectively be provided with a clamping apparatus disk in two ends up and down at the anchor clamps main shaft, the edge circumferentially is evenly distributed with a plurality of mould slots on clamping apparatus disk, bottom at anchor clamps main shaft lower end clamping apparatus disk is provided with one in order to spacing supporting disk, described supporting disk is annular, and supporting disk links to each other by bolt with the clamping apparatus disk of anchor clamps main shaft lower end.Supporting disk has limit function, prevents that the mould pin of capsule die from running into clamping apparatus disk, the damage mould, and supporting disk is the hollow structure of annular simultaneously, so also do not affect flowing of abrasive particle when polishing.
As preferably, on clamping apparatus disk, along the clamping apparatus disk center to external radiation many elongated slots are arranged, described elongated slot is connected with the mould slot, and the width of elongated slot is less than the width of mould slot.Elongated slot flowing of an abrasive particle when being convenient to vibropolish be set, two also are convenient to install capsule die; And the width of mould slot is beneficial to the two ends of capsule die are installed on the clamping apparatus disk greater than the width of elongated slot.
Because the processing length of mould has error, therefore can not guarantee that every die length is in full accord, when platen compresses, the mould of segment section just can not be held down, mould is installed just unstable like this, as preferably, between the clamping apparatus disk of anchor clamps main shaft lower end and supporting disk, be provided with rubber blanket, the shape of described rubber blanket, size and supporting disk are complementary.Like this, behind placement one rubber blanket, the mould of different length can both be pressed surely between the clamping apparatus disk of supporting disk and anchor clamps main shaft lower end.
The invention has the beneficial effects as follows:
The clamping apparatus disk bottom of anchor clamps main shaft of the present invention lower end is provided with supporting disk, and supporting disk can carry out shutoff with the mould slot on the clamping apparatus disk just, prevents that anchor clamps from exposing from the lower end; And supporting disk is annular, does not also affect flowing of abrasive particle when polishing.

The specific embodiment
The specific embodiment of the present invention is as follows:
Embodiment: as shown in Figure 1, a kind of lower fixture disc limiting mechanism of polishing clamp for capsule mold, comprise anchor clamps main shaft 1, two ends respectively be provided with the clamping apparatus disk 2 of a circle at the anchor clamps main shaft about in the of 1, the edge circumferentially is evenly distributed with a plurality of mould slots 3 on clamping apparatus disk 2, simultaneously, many elongated slots 7 are arranged along the clamping apparatus disk center to external radiation on clamping apparatus disk 2, described elongated slot 7 long 7cm, wide 1cm, described elongated slot 7 intersects and is connected with mould slot 3, and the width of elongated slot 7 is less than the width of mould slot 3, so that fixing capsule die 8.
Be provided with one in order to spacing supporting disk 4 in the bottom of anchor clamps main shaft 1 lower end clamping apparatus disk, such as Fig. 2, shown in Figure 3, described supporting disk 4 is annular, the edge is circumferentially with a plurality of installing holes 5 on supporting disk 4, same on the clamping apparatus disk of anchor clamps main shaft 1 lower end also correspondence be provided with installing hole, after both installing hole alignment, after the assembling bolt 6 clamping apparatus disk of supporting disk 4 with anchor clamps main shaft 1 lower end is fixed together.As shown in Figure 2, between the clamping apparatus disk of anchor clamps main shaft lower end and supporting disk 4, be provided with the rubber blanket 9 of annular.
