Abstract
The utility model relates to an inner transmission system of an electric knife grinder, which belongs to the technical field of grinding tools. The utility model is installed between a main shaft of the electric knife grinder and a shaft of a motor which is fixed on a dihedral frame whose end is provided with a shaft hole, and a pivot shaft is installed in the shaft hole and is fixed on a basic frame. A cylindrical transmission wheel is fixed on the end of a main shaft; one end of the cylinder is provided with a web plate to be fixed on the main shaft; the shaft of the motor is butted on the inner margin of the transmission wheel so as to use the friction for driving. The inner margin of the transmission wheel is also covered with a rubber layer so as to enlarge frictional force and extend the service life. The external edge of the end of the transmission wheel is also fixed or connected with a knife blocking wheel whose outer margin is covered with cattle hide. The utility model can raise the grinding efficiency and ensure the grinding quality and has the advantages of simple and compact structure and small volume, and the utility model is especially suitable for the grinding for carpenters, household knives, etc. at low speed.
Description
Technical field
The utility model belongs to the grinding tool technical field, more particularly relates to the improvement of the interior transmission system of the electric knife sharpener that is used for grinding carpenter and family expenses planing tool, chisel, axe, cutter etc.
Background technology
Traditional carpenter and family expenses knife sharpener are grinding stone and abrasive machine.By manual, not only efficient is low, and physical demands is bigger entirely in the use of grinding stone.Abrasive machine has two classes.One class is a hand-driven grinder, shakes abrasive machine during work on the other hand, and another stabs knife milling tool to death, and action is difficult to coordinate, and grinding quality also just is difficult to guarantee.Another kind of is existing electric grinder, and emery wheel rotates at a high speed, not too is suitable for the low speed grinding of carpenter and family expenses planing tool, chisel, axe, cutter etc.
Existing electric grinder is mostly with drive pulley, driven pulley and belt transmission, complex structure.The applicant's No. 03139234.2 patent application discloses a kind of motor shaft and has borrowed frictional force directly to drive drive, and then drive shaft and emery wheel, has saved belt transmission, electric grinder simple in structure.But its kind of drive is outer transmission, and compact conformation, volume are still bigger.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of interior transmission system of electric knife sharpener is provided.It not only can improve grinding efficiency, the assurance grinding quality of knife sharpener, and simple in structure, compact, and volume is less, is particularly suited for the low speed grinding of carpenter and household appliance cutlery etc.
Electric knife sharpener comprises pedestal, be installed in main shaft and motor on the pedestal, be installed in transmission mechanism between main shaft and the motor shaft, be installed in parts such as emery wheel on the main shaft and electric control circuit.
In order to achieve the above object, the utility model is installed between the axle of the main shaft of electric knife sharpener and motor.Motor is fixed on the angular frame, and the end of angular frame has axis hole, and a pivot is installed in the axis hole, and pivot is fixed on the pedestal.Drive is being fixed in the end of main shaft, and drive is cylindric, and an end of cylinder has disc so as to being fixed on the main shaft, the axle of motor abut against on the inner edge of drive with friction-driven it.
Motor outwards is rotated down around pivot together with angular frame because of its deadweight, and it is pressed on the inner edge of drive, with frictional force drives it.During the motor rotation, its axle borrows frictional force that drive is driven, and then drive shaft and emery wheel, finishes the sharpening task.When the grinding resistance that bears on the emery wheel was excessive, the transmission efficiency of this structure can reduce automatically, slows down automatically, avoids causing danger because of locking.
Also coating rubber layer on the inner edge of drive.Rubber layer can increase frictional force, improves transmission efficiency, and can increase the service life.
Also fixing or connecting a pan break bar on the outer of drive end, the outer rim of pan break bar is coating ox-hide.The effect of stropping wheel is " swinging " (pan) cutter, that is removes behind the sharpening the empty sword on the cutting edge and empty burr or the like.
Task of the present utility model comes to this and finishes.
The utility model not only can improve grinding efficiency, the assurance grinding quality of knife sharpener, and simple in structure, compact, and volume is less, is particularly suited for the low speed grinding of carpenter and household appliance cutlery etc.It can be widely used in the places such as wood shop, little handicraft workshop, family.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is its side view cutaway drawing.
The specific embodiment
Embodiment 1.A kind of interior transmission system of electric knife sharpener is as Fig. 1～shown in Figure 2.Electric knife sharpener comprises pedestal 1, be installed in main shaft 2 and motor 3 on the pedestal 1, be installed in transmission mechanism between the axle of main shaft 2 and motor 3, be installed in emery wheel 4 and electric controller on the main shaft 2.
The utility model is installed between the axle of the main shaft 2 of electric knife sharpener and motor 3.Motor 3 is fixed on the angular frame 5, and the end of angular frame 5 has axis hole 6, and a pivot 7 is installed in the axis hole 6, and pivot 7 is fixed on the pedestal 1.Drive 8 is being fixed in the end of main shaft 2, and drive 8 is cylindric, and an end of cylinder 9 has disc 10 so as to being fixed on the main shaft 2.The axle of motor 3 abut against on the inner edge of drive 8 with friction-driven it.
Also coating rubber layer 11 on the inner edge of drive 8.Also fixedly connected pan break bar 12 on the outer of drive 8 ends, the outer rim of pan break bar 12 is coating ox-hide 13.
A water holding box 14 also is installed on the pedestal 1, and insert in the water holding box 14 bottom of emery wheel 4.
Embodiment 1 not only can improve grinding efficiency, the assurance grinding quality of knife sharpener, and simple in structure, compact, and volume is less, is particularly suited for the low speed grinding of carpenter and household appliance cutlery etc.It can be widely used in the places such as wood shop, little handicraft workshop, family.
