Abstract

The utility model is adapted to the field of electromechanical technologies and provides a grinder. The grinder comprises an upper diamond grinding wheel, a lower diamond grinding wheel, and a spacing mechanism, wherein the upper diamond grinding wheel and the lower diamond grinding wheel are made of soft binders, and the spacing mechanism is used to limit workpieces between the upper diamond grinding wheel and the lower diamond grinding wheel. The upper diamond grinding wheel is fixedly connected with an upper abrasive disk driven by an upper motor, and the lower diamond grinding wheel is fixedly connected with a lower abrasive disk driven by a lower motor. The spacing mechanism is driven by a central motor, and the rotation direction thereof is opposite to the rotation direction of the diamond grinding wheels. During grinding, the grinding material of the diamond grinding wheels is abutted against corner angles of the workpieces, and acting forces of the diamond grinding wheels on the corner angles are larger than those on the surfaces of the workpieces, and at the same time, the rotation direction of the spacing mechanism is opposite to the rotation direction of the diamond grinding wheels, so that the upper and lower surfaces of the workpieces can be ground, the grinding degree of the corner angles of the workpieces is obvious, R surfaces are formed, and grinding efficiency and precision are greatly improved.

Description

A kind of grinder

Technical field

The utility model belongs to the mechanical & electrical technology field, relates in particular to a kind of grinder.

Background technology

Carbide alloy is by hard ceramic and the bonding structural material of forming of metal or alloy, and it had both kept characteristics such as ceramic high strength, high rigidity, wear-resistant, high temperature resistant, anti-oxidant and chemical stability, had preferred metal toughness and plasticity again.Because carbide alloy is a kind of adamantine metal, generally use the diamond tool that attrition process is carried out to form the R face in its surface.At present, mainly be to accomplish the R face with diamond pen by hand, the size at R angle is repaiied in the size decision that the Buddha's warrior attendant nib is exposed, and diamond pen is reserved the slit after having repaired section, and then is repaired to section by cylindrical with withdrawing rotation trimmer.But manually accomplish the R face and repair that not only operating efficiency is low, and difficult quality guarantee.

The utility model content

The purpose of the utility model embodiment is the grinder that provides a kind of automaticity and precision all higher.

The utility model embodiment realizes like this; A kind of grinder; It is characterized in that; Said grinder comprises the upper and lower skive processed by soft bond and workpiece is limited in the said position-limit mechanism of going up between skive and the following skive, said on skive be fixed in upper millstone by last driven by motor, following skive is fixed in by the lower millstone that descends driven by motor; Said position-limit mechanism is by the center driven by motor, and the direction of rotation of its direction of rotation and skive is opposite.

The utility model embodiment processes skive by soft bond; Position-limit mechanism is limited in workpiece when grinding between skive and the following skive; The abrasive material of skive will be connected to the corner angle of workpiece, and its power that acts on edges and corners is greater than the power that acts on surface of the work, make the direction of rotation of direction of rotation and skive of position-limit mechanism opposite simultaneously; Can grind the upper and lower surface of workpiece like this; Its corner angle degree of grinding to workpiece will be more obvious, make it to become the R face, greatly promote grinding efficiency and precision.

Description of drawings

Fig. 1 is the general assembly drawing of the grinder that provides of the utility model embodiment;

Fig. 2 is the principle schematic of the grinder that provides of the utility model embodiment;

Fig. 3 is the grinder partial enlarged drawing that provides of the utility model embodiment when place work piece (not);

Fig. 4 is the enlarged drawing of the walking gear sheet that provides of the utility model embodiment.

The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Be described in detail below in conjunction with the realization of specific embodiment the utility model.

Shown in Fig. 1～3; The grinder that the utility model embodiment provides comprises the upper and

lower skive

1,2 processed by soft bond and workpiece is limited in the said position-limit mechanism of going up between skive 1 and the following skive 2; The said skive 1 of going up is fixed in the upper millstone 11 by last driven by motor, and following skive 2 is fixed in the lower millstone 12 by following driven by motor; Said position-limit mechanism is by the center driven by motor, and the direction of rotation of its direction of rotation and skive is opposite.Because of the skive covering property that soft bond is processed good; Position-limit mechanism is limited in workpiece when grinding between skive 1 and the following skive 2; The abrasive material of skive will be connected to the corner angle of workpiece, and its power that acts on edges and corners is greater than the power that acts on surface of the work, make the direction of rotation of direction of rotation and skive of position-limit mechanism opposite simultaneously; Can grind the upper and lower surface of workpiece like this; Its corner angle degree of grinding to workpiece will be more obvious, make it to become the R face, greatly promote grinding efficiency and precision.

Usually, said position-limit mechanism is a plurality of walking gear sheets 14 that mesh simultaneously with central shaft ring gear 10 and outer ring ring gear 13, and each walking gear sheet 14 has a plurality of through holes 15 in order to place work piece; Said central shaft ring gear 10 passes lower millstone 12 and is connected with the center drive of motor, and said middle electrocardiograph drives said position-limit mechanism via central shaft ring gear 10 and rotates.Make the thin thickness of the thickness of said walking gear sheet 14 here, grasp workpiece and carry out twin grinding with following skive 2 thereby be beneficial to skive 1 than workpiece.

When said workpiece was triangle carbide alloy workpiece, said through hole 15 was triangular in shape, and its drift angle place establishes the mesopore 16 that supplies the grinding chip in time to discharge, and is to guarantee the ground effect of follow-up batch of workpiece, as shown in Figure 4.As preferably, diamond particles is evenly distributed in the said skive, makes each corner angle of workpiece and surface grinding even, and the R face uniformity of grinding out is good.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
