Abstract
An electric tool grinder pertains to the grinding machine technology field, which comprises a bed frame, a main shaft, an electric motor, a transmission device, a grinding wheel and an electric control device. The electric motor is arranged on a triangular frame. A pivot is arranged in an axle hole at the end of the triangular frame and the pivot is also fixed on the bed frame. A transmission wheel is arranged on one end of the main shaft. The output shaft of the electric motor contacts the edge of the transmission wheel and the transmission wheel is driven by the friction force between the transmission and the output shaft of the motor. A tool blocking wheel is arranged at outside of the transmission wheel on the main shaft and the outer margin of the tool blocking wheel is covered by cattle hide. The transmission wheel is covered by a rubber layer. A water storage box is arranged on the bed frame and the lower part of the grinding wheel is inserted into the water storage box. A tool carrier is fixed on a fixed frame on the bed frame with two holding screws. The utility model has the advantages of high grinding efficiency, low working intensity and good grinding effect, which is especially suitable for low speed grinding of household planer, chisel, axe and other tools.
Description
Technical field
The utility model belongs to the grinding tool technical field, more particularly relates to the improvement 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.In addition, because of its material, granularity have nothing in common with each other, not necessarily cooperate with the cutter of want sharpening.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.
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of grinding efficiency height is provided, and physical demands is little, can guarantee grinding quality, is particularly suited for the electric knife sharpener of the low speed grinding of carpenter and family expenses planing tool, chisel, axe, cutter etc.
Summary of the invention
In order to achieve the above object, the utility model comprises pedestal, is installed in main shaft and motor on the pedestal, is installed in transmission mechanism between the axle of main shaft and motor, is installed in emery wheel and electric control circuit on the main shaft.Motor is installed on the angular frame, and the end of angular frame has axis hole, and a pivot is installed in the axis hole, is pivotally mounted on the pedestal.Drive is being fixed in the end of main shaft, the axle of motor abut against on the edge of drive with friction-driven 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.The rubber layer that the drive outside is coating can increase frictional force, improves transmission efficiency.
A pan break bar is also being fixed in the outer end of installation drive one end of main shaft, and the outer rim of pan break bar is coating ox-hide.The effect of pan break bar is " a pan cutter ", and meaning is promptly removed behind the sharpening the empty sword on the cutting edge and empty burr or the like.
A water holding box also is installed on the pedestal, and insert in the water holding box bottom of emery wheel.The wettable emery wheel of water in the water holding box is beneficial to grinding.
Also fixing fixed mount in the pedestal.Also have two installing holes above the pedestal, knife rest is installed in the installing hole.The pedestal front also has two screws, and two holding screws are installed in the screw, and holding screw is fixed on the lower end of knife rest on the fixed mount.During sharpening, will be resisted against on the knife rest, help its positioning stablity, to guarantee grinding quality by knife milling tool.
Motor then is rotated down from recoiling pivot by it, and its axle is pressed on the transmission wheel rim.
The utility model provides a kind of grinding efficiency height, and labour intensity is little, can guarantee grinding quality, is particularly suited for the electric knife sharpener of the low speed grinding of carpenter and family expenses planing tool, chisel, axe, cutter etc.It can be widely used in the places such as wood shop, little handicraft workshop, family.

The specific embodiment
Embodiment 1.A kind of electric knife sharpener is as Fig. 1～shown in Figure 3.It 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 control circuit on the main shaft 2.Motor 3 is installed 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.Pivot 7 is installed on the pedestal 1.Drive 8 is being fixed in the end of main shaft 2, the axle of motor 3 abut against on the edge of drive 8 with friction-driven it.A pan break bar 9 is also being fixed in the outer end of installation drive 8 one ends of main shaft 2, and the outer rim of pan break bar 9 is coating ox-hide 10.The outside of drive 8 is also coating one deck rubber layer 15.
A water holding box 11 also is installed on the pedestal 1, and insert in the water holding box 11 bottom of emery wheel 4.Consult Fig. 4, also fixing fixed mount 12 in the pedestal 1.Also have two installing holes above the pedestal 1, knife rest 13 is installed in the installing hole.Pedestal 1 front also has two screws, and two holding screws 14 are installed in the screw, and holding screw 14 is fixed on the lower end of knife rest 13 on the fixed mount 12.
Embodiment 1 grinding efficiency height, labour intensity is low, and good grinding quality is particularly useful in the low speed grinding of carpenter and family expenses planing tool, chisel, axe, cutter etc.
