Abstract
The utility model discloses a polishing head of an automatic polisher for precision plastic parts. The polishing head comprises a hollow column body and multiple pieces of abrasive paper. The multiple pieces of the abrasive paper are arranged on the outside of the column body. The polishing head is characterized in that the outer surface of the column body is evenly provided with integrally-molded clamping grooves in the longitudinal direction of the column body, and opening ends formed after the multiple pieces of the abrasive paper are folded are installed in the clamping grooves in the outer edge face of the column body. The outer surface of the column body is provided with the clamping grooves, the folded abrasive paper is installed in the clamping grooves to form fan blades, flexible polishing of the outer shell plastic parts can be achieved, polishing efficiency of the outer shell plastic parts is improved, and meanwhile polishing quality of the outer shell plastic parts is also improved.
Description
Technical field
The utility model belongs to precise injection mould part processing unit (plant) technical field, relates to a kind of mechanical fitting, is specially a kind of grinding head of precise plastic part automatic sander.
Background technology
At present, the digital product of more and more diverse in function gets their way into people's lives, and more and more lightening, the shell of digital product adopts plastic material to be made into integration by precise injection molding mostly, the further processing processing after the digital product shell plastic that injection moulding is finished also needs through the manual polishing processing of traditional Shooting Technique, manual polishing not only labour intensity is large, and product quality can't guarantee.Although the tradition sander has reduced workman's labour intensity, but the grinding head of grinding machine mostly is the column by motor driving, damaged surface is pasted with sand paper, by the motor driving grinding head burr of shell plastic is polished, but the sand paper of this grinding head is fixed, and harder, scratches easily the plastic surface in the polishing engineering of plastic burr, affect product quality, production efficiency is not high yet.
The utility model content
For existing above-mentioned deficiency in the prior art, the purpose of this utility model is to provide a kind of grinding head of precise plastic part automatic sander, can realize the flexibility polishing of shell plastic, in the production efficiency that improves the shell plastic, also improve the polishing quality of shell plastic.
For achieving the above object, the utility model will be achieved through the following technical solutions:
A kind of grinding head of precise plastic part automatic sander, the cylinder and the sand paper that comprise hollow, described sand paper is arranged on the outside of cylinder, it is characterized in that: the outer surface of described cylinder vertically evenly is provided with integrated draw-in groove along cylinder, and the openend after the described sand paper doubling is installed in the draw-in groove of described cylinder outside face.
The outer surface that is installed in cylinder after the sand paper doubling is arranged in the draw-in groove, form soft flabellum, when the grinding machine that this grinding head is installed is polished, the sand paper of flabellum shape is in the direction low-disturbance power opposite with direction of rotation, centrifugal force by rotation is polished to plastic, realize the flexibility polishing of shell plastic, improved grinding efficiency and the polishing quality of shell plastic; In addition, sand paper is installed by draw-in groove, is convenient to change, and is conducive to the raising of production efficiency.
For sand paper is installed to firmly, as preferably, the cross sectional shape of described draw-in groove is trapezoidal or circular.
Be further to improve the flexibility of sand paper, as preferably, described sand paper comprises spongy layer and sandy gravel stratum.
Concrete, sandy gravel stratum adopts the mode of hot pressing to be fitted in described spongy layer surface by viscose glue.
The utility model has the following advantages and beneficial effect compared to existing technology:
The utility model is by arranging draw-in groove at the outer surface at cylinder, and the sand paper of doubling is installed in and forms flabellum in the draw-in groove, can realize the flexibility polishing of shell plastic, also improved the polishing quality of shell plastic in the grinding efficiency that improves the shell plastic.

Fig. 2 is the top view of the grinding head of a kind of precise plastic part automatic sander of the utility model.
Fig. 3 is the structural representation of sand paper in the utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment as depicted in figs. 1 and 2, a kind of grinding head of precise plastic part automatic sander, the cylinder 1 and the sand paper 2 that comprise hollow, described sand paper 2 is arranged on the outside of cylinder 1, the outer surface of described cylinder 1 vertically evenly is provided with integrated draw-in groove 11 along cylinder, and the openend after described sand paper 2 doublings is installed in the draw-in groove 11 of described cylinder 1 outside face.
As preferably, the cross sectional shape of described draw-in groove 11 is trapezoidal.
As preferably, as shown in Figure 3, described sand paper 2 comprises spongy layer 21 and sandy gravel stratum 22.
Particularly, sandy gravel stratum 22 adopts the mode of hot pressing to be fitted in described spongy layer 21 surfaces by viscose glue.
Above-described embodiment is the better embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
