Abstract

The utility model relates to spiral type sanding bar sanding roll, which comprises a sanding roll body consisting of one or a plurality of sanding sheets. Sanding bar inserting slots are arranged on the sanding roll body, and the sanding bar inserting slots of the sanding roll body are spirally arrayed along an axial direction of the sanding roll. Cross section of each sanding bar inserting slot is swallow-tailed, a swallow-tailed clip is arranged inside each swallow-tailed sanding bar inserting slot, and the swallow-tailed clips hold bristles and emery cloth belts. Parallel grooves on the surface of an original sanding roll are changed into threaded concave pits, and a line and surface sanding form of the original sanding roll is changed into a point and surface sanding form, and then sanding traces can not leave on surfaces of work pieces. In addition, because of change of cutting angles, sanding effect to concave and convex surfaces is better, thereby further reducing labor intensity of workers and replacing manual sanding of the workers. By utilizing a mounting form of combining the swallow-tailed clips with the swallow-tailed grooves, the spiral type sanding bar sanding roll is more compact and reasonable in structure. Besides, the bristles or emery cloth belts in the sanding bar can be replaced optionally according to needs, thereby greatly reducing production cost compared with a traditional structure needing to replace the sanding bar integrally.

Description

Spiral emery stick sand is cut roller

Technical field

The utility model relates to a kind of woodenware processing equipment, specifically, relates to the employed sand of a kind of curved surface sander and cuts burnishing device.

Background technology

Existing sand is cut and has nearly all been used hairbrush, emery stick in the roller, and the mounting means that mostly adopts parallel sand to cut roll axis fixes hairbrush and emery stick, it as the patent No. 200620148921.3 utility model patent, but line, facing sand that the polishing wheel in this patent uses are cut mode, are easy to generate the sand trace; Hairbrush nearly all adopts the hole of plastic basis material to plant formula simultaneously, and emery stick nearly all adopts the clipping of independent base material, and physical dimension is bigger, and can not repeat to re-use, and can waste a large amount of base materials during replacing, causes increasing of manufacturing cost.

Summary of the invention

It is poor that the purpose of this utility model is that the sand in the existing sander is cut the polishing effect that burnishing device exists, the deficiency of unreasonable structure, and the novel screw type emery stick sand that provides a kind of sand to cut strip adoption helical arrangement mode is cut roller.

Solution of the present utility model is: a kind of spiral emery stick sand is cut roller, comprises by one or more pieces sand sand that constitutes of chipping cutting roll body, and sand is cut and had the emery stick slot on the roll body, the emery stick slot that described sand is cut roll body along sand cut roller axially in the shape of a spiral shape arrange.

Preferably, described emery stick slot cross section is dovetail shaped, is provided with a dovetail folder in swallow-tailed emery stick slot, and this dovetail clamps bristle and emery cloth strip.

Preferably, described sand is cut roller and is chipped by multi-disc sand and combine, and the central authorities that sand is chipped are provided with the rotating shaft through hole, and all sand is chipped and is installed in the rotating shaft by the rotating shaft through hole, and encapsulate by the round baffle plate at rotating shaft two ends, fastening by round nut again in the outside of circle baffle plate.

Preferably, the diameter of described round baffle plate is not less than the diameter that sand is chipped.

Preferably, synchronous in order to guarantee that rotating shaft and sand are chipped and rotated, one end of described rotating shaft has and is used to block the circular card edge that sand is chipped, the arranged outside that the sand of the other end is chipped has a round nut, utilize the circle baffle plate to encapsulate in the outside of card edge and round nut, the outside of the round baffle plate at two ends is fastening by round nut again; Perhaps, described rotating shaft and sand are chipped and are provided with protruding key and the keyway that is complementary between the rotating shaft through hole.

The beneficial effects of the utility model are: at first, original sand is cut the parallel groove on roller surface, changes the screw thread spill into, with line, the facing sand mode of cutting change point into, facing sand is cut mode, can not stay sand sheeter lines mark at surface of the work like this.And, further reduce working strength of workers because the change at cutting angle is cut better effects if to the sand of convex-concave surface, replace workman's manual sand to cut; Adopt the combination mounting means of dovetail folder and dovetail groove, structure is more compact, reasonable, and can arbitrarily change bristle or meche in the emery stick as required, the structure that needs the integral replacing emery stick more in the past, and production cost reduces greatly.

The specific embodiment

First specific embodiment of the present utility model as shown in Figures 1 to 4, a kind of spiral emery stick sand is cut roller, comprise by multi-disc sand 1 sand that constitutes of chipping and cut roll body, sand is cut and is had emery stick slot 2 on the roll body, the emery stick slot 2 that described sand is cut roll body along sand cut roller axially in the shape of a spiral shape arrange.Dovetail folder 5 is installed in swallow-tailed emery stick slot 2, and this dovetail folder 5 clamps bristle 9 and emery cloth strip 10.Chip 1 central authorities of sand are provided with rotating shaft through hole 3, all sand is chipped and is installed in the rotating shaft 4 by rotating shaft through hole 3, and encapsulate by the round baffle plate 6 at rotating shaft 4 two ends, the diameter of circle baffle plate 6 is not less than chip 1 diameter of sand, and is fastening by round nut 8 again in the outside of circle baffle plate 6.Synchronous in order to guarantee that rotating shaft and sand are chipped and rotated, one end of described rotating shaft has and is used to block the circular card edge that sand is chipped, the arranged outside that the sand of the other end is chipped has a round nut, utilize the circle baffle plate to encapsulate in the outside of card edge and round nut, the outside of the round baffle plate at two ends is fastening by round nut again.

During installation, at first according to treating that sand cuts the Workpiece length of polishing, width, select chip 1 quantity of sand, and it is installed in the rotating shaft 4, note chip the emery stick slot 2 spiral alignment vertically on 1 of all sand during installation, and with in the middle of the emery stick 7 insertion slots, utilize round nut and card the cooperating of edge, make sand chip 1 with rotating shaft 4 between have bigger frictional force, to protect rotate synchronous between the two, circle baffle plate 6 is installed at two ends then, and fixes with disk nut 8 and to get final product.

Perhaps, described rotating shaft and sand are chipped and are provided with protruding key and the keyway that is complementary between the rotating shaft through hole.
