Abstract
The invention relates to an electrical grinding machine which comprises an engine body, a head shell, an output shaft and a grinding head, wherein the output shaft is arranged in the head shell through a front bearing and a rear bearing, the front end of the output shaft is connected with the grinding head, the rear end of the output shaft is connected with a motor shaft in the engine body through a coupler, a cooling fan is arranged on the output shaft, air passages are arranged on the periphery of the inner side wall of the head shell, an air inlet and an air outlet which are communicated with the air passages are respectively arranged in the head shell, a cooler is arranged on the coupler, heaves are arranged on the grinding head, and scraper blades are arranged on the grinding shaft nearby the grinding head. The cooling fan is arranged on the output shaft, and the cooler is arranged on the coupler, thus the electrical grinding machine has a good heat dissipation effect, and is not easily worn because the triangular heaves are arranged on the grinding head.
Description
Technical field
The present invention relates to a kind of electric tool, relate in particular to a kind of electrical grinding machine.
Background technology
High because of rotating speed during electrical grinding machine work, the time one is long, and bearing can produce a large amount of heats, cause the electrical grinding machine head capsule overheated, so that the operator is difficult to work on, and also can greatly shorten the service life of electrical grinding machine, only by air inlet and air outlet cooling, radiating effect is not good.The long-time use easily of the bistrique of common electrical grinding machine worn and torn, and changing bistrique not only increases cost, has also reduced operating efficiency.Therefore, need a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The purpose of this invention is to provide a kind of automatic cooling, nonabradable electrical grinding machine.
The technical solution used in the present invention is:
A kind of electrical grinding machine, comprise body, head capsule, output shaft and bistrique, described output shaft is arranged in the head capsule by forward and backward bearing, described output shaft front end is connected with bistrique, described output shaft rear end is connected with motor shaft in the body by shaft coupling, described output shaft is provided with cooling fan, be provided with ventilation slot around the madial wall of described head capsule, described head capsule is provided with air inlet and the air outlet that is connected with ventilation slot respectively, described shaft coupling place is provided with cooler, described bistrique is provided with projection, and the grinding head shaft at close bistrique place is provided with wing.
Described projection is triangle.
Described body tail end is provided with the damping handgrip, and described damping handgrip and body junction are provided with buffer stopper.
On the output shaft of the present invention cooling fan is housed, the shaft coupling place is provided with cooler, and head capsule is provided with air inlet and the air outlet that is connected with ventilation slot respectively, this structure good heat dissipation effect, grinding head shaft near the bistrique place is provided with wing, before the use bistrique, can tentatively strike off workpiece with wing first, and bistrique is provided with triangular hill, not easy to wear, when electrical grinding machine used, impulsive force was more intense, the buffer stopper at damping handgrip place can reduce impact.
