Description
Technical field
The utility model relates to a kind of instrument of removing burr, particularly relates to a kind of rotary cut device of removing injecting hole burr in moulding and injecting hole being carried out simultaneously chamfering.
Background technology
Plastics are macromolecular materials, have that high strength, high-ductility, antifriction are anticorrosion, plastic processing Performance Ratio natural timber and metal material good, plastics industry is one of mark of chemical industry up-to-dateness, plastics industry, along with the development of national economy, has been deep into the every aspect of industry and daily life, in industry and daily life, plastic products are be unable to do without, although the good processability of plastics, in some aspects, still there is difficult point in processing.
After injection molding, on surface and inside all can produce some burrs, the burr of outer surface is easy to cleaning, but the burr of enclosure interior, is very difficult to cleaning, the especially burr at the injecting hole place of some thin-walled injection moulding parts, if do not cleared up, can affect assembly quality, still due to the plasticity of material, be easy to obstruction, adhesion cutter, and thin-walled injection moulding part needs the cutter holding of particular design, cost effectiveness is large, and labor cleaning, efficiency is lower, and breakage rate is larger, time-consuming, be also easy to hinder hand, have a strong impact on manufacturing schedule and product quality.
Therefore need badly a kind of simple in structurely, easily install easy to operately, production efficiency is high, the novel burr rotary cut device that breakage rate is low.
Utility model content
The purpose of this utility model is to provide a kind of quick location, does not glue glutinous injecting hole burr rotary cut device without clamping, viscous plastic bits.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of injecting hole burr rotary cut device, wherein, include base, back shaft, bite, locating turntable and adjustment screw, base center is fixed in described back shaft bottom, described back shaft middle part connects a locating turntable by bearing, described locating turntable and bearing are by the shaft shoulder location of back shaft self, and described locating turntable upper surface forms horizontal support platform, and described back shaft top vertical arranges blind hole downwards; Described bite comprises cutter head, elevating lever, and described cutter head is positioned at elevating lever upper end, and insert in blind hole described elevating lever lower end, and described cutter head has rotary-cut sword; On sidewall outside described back shaft upper blind bore, through hole is set and adjustment screw is installed.
Wherein, described cutter head cross sectional shape is lower large little trapezoidal or umbrella shape, and described bite, centered by the cutter head center of circle, has trapezoidal or umbrella shape inclined-plane as rotary-cut sword, and formation chip area caves inward between described rotary-cut sword.
Wherein, the cutter head of described bite and elevating lever are detachable.
The beneficial effects of the utility model are:
1, whole mechanism, without fixture, without moulding being clamped to operation, increases production efficiency.
2,, without the bite of High Rotation Speed, can not produce the sticky problem that sticks bite of smear metal that high temperature friction causes.
3, simple in structure, the burr of a moulding endoporus of cleaning only needs 3-4 second, and breakage rate is extremely low.
4, determine proper height by locating turntable and elevating lever, the injury of avoiding bite may cause workman, safety coefficient is high.
5, simple to operate, easy to maintenance, be suitable for the deburred in thin-walled injection moulding part in enormous quantities hole.

The specific embodiment
Following examples are only for the utility model example is clearly described, and the not restriction to embodiment of the present utility model.For those of ordinary skill in the field; on the basis of following explanation, can also make other multi-form variation or variations, and these belong to apparent variation that the utility model spirit draws or variation still among protection domain of the present utility model.
Embodiment mono-
As Fig. 1, shown in Fig. 2, a kind of injecting hole burr rotary cut device of the present utility model comprises base 1, locating turntable 2, bearing 3, back shaft 4, elevating lever 5, adjustment screw 6, bite 7, described base 1 is a disk or circular flange, described base 1 center and back shaft 4 bottoms are fixed, fixed form can adopt screw thread to fix or weld all can, described back shaft 4 middle parts are connected and fixed locating turntable 2 by a bearing 3, described bearing 3 and locating turntable 2 are all located by the shaft shoulder of back shaft 4 self, the upper surface of described locating turntable 2 is horizontal support platform 21, described back shaft 4 top verticals arrange blind hole downwards, as shown in Fig. 3,4,5, described bite 7 is made up of cutter head 71, elevating lever 5, described cutter head 71 is positioned at elevating lever 5 upper ends, insert in the blind hole on back shaft 4 tops described elevating lever 5 lower ends, and elevating lever 5 radiuses and blind hole loose fit, sidewall outside described back shaft 4 upper blind bore is got through hole and adjustment screw 6 is installed, and described adjustment screw 6 is for fixing elevating lever 5.
