Description
Technical field
The utility model relates to a kind of machine tools, is specially a kind of clamping device of mould thimble, and this clamping device is used for when polishing mould thimble length and cross section flatness the mould thimble being fixed.
Background technology
Thimble is swaging dies such as compression mod, plastic mould accessories commonly used, is used at mould the product of moulding being separated from mould, and it also is the most frequently used a kind of delivery utensil.The kind of mould thimble is also a lot of at present, and flat thimble, dome pin, holder pin, standard thimble, non-standard thimble etc. are arranged.The basic structure of mould thimble is a metal pushrod with strip, the one end is arranged to the connector of the big slightly annulus of diameter or other shapes, the other end is arranged to flat, circle etc. as required, during use the first end of the connection of mould thimble is fixed on the ejector pin mechanism, drive before and after the mould thimble or move up and down by ejector pin mechanism, the other end that makes the mould thimble is to the product applied thrust, thereby product is separated from mould.Because the size difference of different moulds and ejector pin mechanism are different with mold interval, thimble size, length that various device uses are also inequality, therefore when making the mould thimble, also need to be polished in the length and the cross section of the mould thimble after the moulding, to satisfy the actual demand of using.
At present, when the mould thimble is polished, be after with anchor clamps the mould thimble being gripped, to place again and carry out attrition process on the grinding machine.The structure of existing mill thimble anchor clamps normally is made up of fixed head, positioning collet, mobile chuck, handle and handle holder, wherein positioning collet and handle holder all are fixed on the fixed head, handle is threaded with the handle holder, mobile chuck is connected with an end of handle and can slides on fixed head, can regulate distance between mobile chuck and the positioning collet by rotary handle.During use mould thimble to be processed is clamped between mobile chuck and the positioning collet, by turning handle thimble is clamped, the height of fixed head upper edge is the height of polishing back mould thimble.In actual production,, therefore need mill thimble anchor clamps also can adapt to the different size demand because different equipment all has nothing in common with each other to the length of mould thimble and the demand of diameter.But the height of present this mill thimble anchor clamps is fixed, the length of polishing back center also can only be fixed, and the therefore thimble that this anchor clamps can only fixed processing length is if process the thimble of another kind of length, then need to change the anchor clamps that are of convenient length, this has also caused cost waste; And when attrition process, traditional mill thimble anchor clamps volume is bigger, and precision is also relatively poor, and is also very inconvenient during use.At present some other mould applying units when changing thimble, are the length that adopts manual mill to get thimble, and this thimble that grinds length is extremely unstable, and the end face of thimble is coarse but also easily by mill tiltedly, cause and can't use.
Summary of the invention
At above-mentioned deficiency of the prior art, main purpose of the present utility model is to solve the problem that the anchor clamps that use at present can't be applicable to the thimble of all lengths when determining mould thimble length, and a kind of mould thimble that is applicable to definite different length size is provided, and clamping device easy to use.
The technical solution of the utility model: a kind of mould thimble clamping device is characterized in that comprise overcoat and interior cover, described interior cover is to be made of sliding bar and limited block; One end of described overcoat links to each other with preceding guide head, the other end of overcoat with in the sliding bar that puts be slidingly connected, on the limited block of interior cover, be connected with the back guide head; In interior cover, preceding guide head and back guide head, be equipped with to be used to place and wait to polish the passage of mould thimble, and the passage in interior cover, preceding guide head and the back guide head is interconnected; Also be provided with first bolt of cover in being used for fixing on the coat, on preceding guide head, be provided with second bolt that is used for fixing the mould thimble of waiting to polish.
During use, the push rod of mould thimble is penetrated interior cover from the passage of back guide head, the passage through preceding guide head passes again, and first end of the connection of mould thimble and back guide head are pushed against, and purpose is to make the push rod of mould thimble all to enter in the passage; Then according to the length of required mould thimble, sliding inner sleeve to the left or to the right, the entire length that makes clamping device equate with required push rod length, can be by slide measure when measuring the length of clamping device, it is more accurate to overlap slip in can making like this, the error after reducing to polish.After having determined the length dimension of clamping device, screw that first bolt pushes against interior cover and fixing, screw second bolt again the push rod of mould thimble is fixed, and then check length one time.The outside vertical plane of guide head is with the vertically cutting or the polishing of push rod of mould thimble before being close to the cutter on lathe or the sanding apparatus at last, and cutting or polishing back form a level and smooth cross section on push rod.
Further, also be fixed with a fixed head in the lower end of overcoat, described fixed head is provided with screw.The effect of fixed head is and clamping device can be fixed on corresponding lathe or the sanding apparatus, makes push rod nearer from sanding apparatus when cutting or polishing like this, and is more convenient to operate, also more laborsaving.
Further, an end of described preceding guide head is provided with conical connecting hole, and the passage in the preceding guide head is by the channel connection in described connecting hole and the interior cover.The little conical structure of imperial palace outside this connecting hole that is provided with on preceding guide head adopts, and make the outside diameter of connecting hole and the channel diameter in the interior cover basic identical, can avoid like this when penetrating the mould thimble making push rod be stopped by the sidewall of preceding guide head because the diameter of preceding guide head internal channel is less; What be provided with that the connecting hole rear push-rod just can be level and smooth passes passage in the clamping device.
With respect to prior art, the utlity model has following advantage:
1, applied widely: the interior cover that is provided with adjustable length in the clamping device of the present utility model, slip by interior cover is the length of alignment jig flexibly, just the length of required mould thimble can be determined after being placed on the mould thimble in the anchor clamps, so just can satisfy the demand of different length mould thimble; And the guide head at two ends can also be changed according to the demand of different-diameter thimble, and its aperture is complementary, and is more firm during clamping like this; And adopted slide measure to measure during the length that cover slides in regulating, make that also the thimble length after polishing is more accurate.
2, easy to use: the volume of this clamping device is littler, fixed head by the bottom can also be fixed on clamping device on the lathe, and is more laborsaving during operation, and when in regulating, overlapping length, adopt the mode of sliding also flexible more, quick, its whole cost is also lower.
