Abstract

The utility model relates to milling tool fields, more particularly to a kind of mixing roll, it include: connection sleeve, stop sleeve and grinding layer, grinding layer is the abrasive sheet being coated on stop sleeve, abrasive sheet includes nylon matrix and the abrasive grains that are adhered on nylon matrix, mixing roll is mounted on driving motor by connection sleeve and is rotated under driving motor effect, work surface is ground using abrasive grains, polishing or wire drawing, since the nylon matrix of grinding layer has certain elasticity, therefore it is processed to grind some male and female faces or knee, the abrasive grains being adhered on nylon matrix improve the wearability and grinding force of grinding layer, improve grinding efficiency, extend service life.

Description

A kind of mixing roll

Technical field

The utility model relates to milling tool field more particularly to a kind of mixing rolls.

Background technique

Grinding be finished surface is carried out by lap tool and the relative motion of workpiece under a certain pressure finished machined (such as Machining).Grinding can be used for processing various metals and nonmetallic materials, and the surface shape of processing has plane, inside and outside cylindrical surface And circular conical surface, convex, concave spherical surface, screw thread, the flank of tooth and its alloytype face.

Common mixing roll is divided into abrasive hardcoat roller and hairbrush mixing roll currently on the market, and wherein abrasive hardcoat roller can not be used The grinding force of grinding in internal concave surface and knee, hairbrush mixing roll is lower, and wear resistance is poor, and service life is low, at high cost.

Utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and providing one kind can grind Mill convex-concave and flexure plane have the mixing roll of stronger wearability again.

The utility model is to be achieved by the following technical programs:

A kind of mixing roll characterized by comprising connection sleeve, stop sleeve and grinding layer,

The keyway for being mounted on machine shaft is equipped in the connection sleeve,

The stop sleeve is socketed in outside connection sleeve, is connected and is passed through adhesive bonding between sleeve and stop sleeve,

The grinding layer is the abrasive sheet being coated on stop sleeve, viscous by adhesive between abrasive sheet and stop sleeve It closes, the abrasive sheet includes nylon matrix and the abrasive grains that are adhered on nylon matrix.

Preferably, the nylon matrix is that more nylon yarns process the mesh sheet to be formed by squeeze roll.

Preferably, the grinding layer with a thickness of 1.3-1.5cm.

The beneficial effects of the utility model are:

Mixing roll is mounted on driving motor by connection sleeve and is rotated under driving motor effect, using grinding Abrasive particle grinds work surface, polish or wire drawing can since the nylon matrix of grinding layer has certain elasticity To improve the wear-resisting of grinding layer for processing some male and female faces of grinding or knee, the abrasive grains being adhered on nylon matrix Property and grinding force, improve grinding efficiency, extend service life.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

In figure: 1. connection sleeves, 2. stop sleevees, 3. grinding layers, 4. nylon yarns, 5. abrasive grains, 6. keyways.

Specific embodiment

In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing The utility model is described in further detail with most preferred embodiment.

As shown, the utility model includes: to connect sleeve 1, stop sleeve 2 and grinding layer 3,

The keyway 6 for being mounted on machine shaft is equipped in the connection sleeve,

The grinding layer is the abrasive sheet being coated on stop sleeve, viscous by adhesive between abrasive sheet and stop sleeve Close, be to be bonded abrasive sheet and stop sleeve by mould in the present embodiment, mould include two be oppositely arranged half Stop sleeve is placed among mould, first in stop sleeve outer application adhesive by abrasive sheet along clamping plate by round clamping plate Two jaws closes are in close contact abrasive sheet and stop sleeve by evenly distributed setting by mould driving device later, from And bond abrasive sheet and stop sleeve, simultaneously because the clamping action of clamping plate can reduce the seam between two neighboring abrasive sheet Gap, the abrasive sheet include nylon matrix and the abrasive grains being adhered on nylon matrix 5.

Mixing roll is mounted on driving motor by connection sleeve and is rotated under driving motor effect, using grinding Abrasive particle grinds work surface, since the nylon matrix of grinding layer has certain elasticity, is processed to Some male and female faces or knee are ground, the abrasive grains being adhered on nylon matrix improve the wearability and grinding of grinding layer Power improves grinding efficiency, extends service life.

Preferably, the nylon matrix is the mesh sheet that more nylon yarns 4 are formed by Roller Machining, grinding in the present embodiment Mill layer is in the fabrication process first squeezed out nylon particles by extruder high temperature, and nylon yarn is quickly cooled in cold water, Nature curling can occur due to being quickly cooled down nylon yarn, then more nylon yarns are formed by Roller Machining in irregular shape is in Nylon mesh sheet is cut into the unified nylon matrix of shape size using guillotine later, will cut by cellular nylon mesh sheet Nylon matrix immerse adhesive in, fill adhesive in nylon matrix surface and hole, abrasive grains be sprayed on nylon It on matrix, is adhered to it in surface and hole of nylon matrix, can be prepared by abrasive sheet after high temperature is dried, due to grinding Grain is uniformly adhered in the hole of nylon matrix, therefore the grinding performance of abrasive sheet will not disappear with the abrasion of outer layer abrasive sheet It consumes and reduces, there is good flexible and grinding force always, the dust generated in process of lapping also can be in nylon yarn honeycomb knot It is removed and is adsorbed under the action of structure, ensure that working environment health, the work safety of employee and health.

Preferably, the nylon matrix with a thickness of 1.3-1.5cm, can prevent while guaranteeing grinding layer severity of grind Only grinding layer excessively softness causes grinding layer to deform.

The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
