Abstract

The utility model relates to a miniature machine for sharpening teeth of the saw disc; the utility model is a carpenter machinery contrivance. The structure is that a clamping angle plate is integrated with a bottom slide plate; a top slide plate slides along the bottom slide plate; a support seat is installed on the top slide plate; a motor is installed on a motor angle modulation seat; an abrasion wheel is arranged on a motor shaft; the lower arm of the crank interlocking bar is connected to the top slide plate; the interlocking bar is installed on the support seat which is arranged on the bottom slide plate; a deflector rod is also arranged on the interlocking bar. The top slide plate moves towards the saw tooth when the crank is swung, which drives the abrasion wheel for sharpening in an annular saw gullet. The machine overcomes the defects of handwork file in abrasive paper edge and steps the mechanized operation. The machine clamping is fixed on a saw bench, so the saw disc does not be detached. And the utility model is simple in use, light in weight and convenient in installation and removing.

Description

The miniature gear grinding machines of saw blade

The utility model relates to the miniature gear grinding machines of a kind of saw blade, is that a kind of carpenter uses machine tool.

Usually during the circular saw fit all by hand file repair sword, work efficiency is low, and sawtooth is different in size, sharpening gets depth inequality, sawtooth differs greatly, like this when cutting timber, the painstaking degree of depth inequality of sawtooth, sawtooth sword quick abrasion is made troubles to work.

The utility model purpose provides the miniature gear grinding machines of a kind of saw blade, overcomes above-mentioned defective, realizes the mechanization reconditioning, sawtooth grinding precision height, and the saw sword is stressed evenly, and mounting or dismounting are convenient.

The utility model purpose is to realize like this; The miniature gear grinding machines of a kind of saw blade is characterized in that its clamping bent plate and lower skateboard are one, and clamping bent plate lower shoe is equipped with hold-down screw.Upper slide and lower skateboard contact-making surface are oat tail groove structure, and upper slide can slide along lower skateboard.Bearing is contained on the upper slide, and the upper supporting plate of bearing connects the motor angle adjustment seat by bolt, and motor is vertically mounted on the angular adjustment seat, and the rotating shaft of motor lower end is equipped with emery wheel.

The lower end of handle gangbar is connected on the sidewall of upper slide by screw, gangbar is installed on the carrier base by pivot pin, and carrier base is installed on the lower skateboard sidewall, and the middle part of gangbar is equipped with adjustable sleeve, driving lever is inserted in the adjustable sleeve, and the driving lever front end can stretch in the saw blade teeth groove.

Lower skateboard extends the damping adjustable plate is installed on two auricles, leans the saw blade two sides by the damping screw.

Description of drawings

Fig. 1-the utility model structural representation.

The side direction structural representation of Fig. 2-Fig. 1.

In conjunction with the accompanying drawings the utility model structure is specified.

The clamping bent plate 1 and the lower skateboard 2 of the miniature gear grinding machines of saw blade are one, and hold-down screw 23 is housed on the bent plate lower shoe, are fixed in during use on the sawing machine platform.Upper slide 3 is designed to oat tail groove structure with lower skateboard 2 contact-making surfaces, and upper slide 3 horizontally slips (Fig. 1) with lower skateboard 2, and movement clearance is regulated by screw 24 between the slide plate.Bearing 4 is installed on the upper slide 3, bearing upper end support plate is inserted in the groove of motor angle adjustment seat 9, be connected by bolt 25, there is deep-slotted chip breaker the two sides of angular adjustment seat 9, motor 7 vertical direction are installed on the angular adjustment seat 9, emery wheel 8 is installed on the motor shaft by emery wheel terminal pad 5, and the emery wheel angular adjustment is to realize to change different angles by the deep-slotted chip breaker diverse location on the moving motor angle adjustment seat 9.Handle 13 gangbar 12 of ining succession, its lower end arm is connected by screw 20 on the sidewall of upper slide 3, and gangbar 12 is installed on the carrier base 11 by pin bolt 21, and carrier base 11 is installed on the lower skateboard 2 by screw 26.Handle 13 is by the swing of the diagram direction of arrow, can make upper slide 3 advance or retreat along slide plate 2, and the motor 7 and the emery wheel 8 that are installed in equally on the bearing can advance or retreat simultaneously, and emery wheel 8 is entered in circular saw bit 10 sawtooth, carry out the reconditioning sawtooth.

At gangbar 12 middle parts adjustable sleeve 14 is installed, driving lever 15 is inserted in the sleeve, and driving lever 15 length variations are to rely on the flexible realization of adjustable sleeve, and driving lever 15 is extend in the sawtooth of saw blade 10.

Because gangbar 12 is around the pin bolt swing, the driving lever direction of motion is opposite with the grinding wheel movement direction like this.When swing handle 13 during to left movement, upper slide 3 advances to the right, orders about in the sawtooth that emery wheel 8 enters saw blade 10 the reconditioning sawtooth.Driving lever 15 withdraws from the serrated slot of saw blade simultaneously, drops on the moving next sawtooth automatically in the driving lever top.Behind the intact tooth of emery wheel reconditioning sawtooth, handle 13 moves right, and at this moment, emery wheel 8 withdraws from sawtooth, and when driving lever 15 entered serrated slot simultaneously, driving lever 15 promoted saw blade and rotates a tooth, and this moment, the emery wheel progressive position just in time was the reconditioning state of next tooth of saw blade.Enter the sawtooth displacement in order to control emery wheel 8, be provided with the forward and backward screw 27 of giving up the throne at the left and right end place of upper slide 3; When upper slide 3 advances to the front limit screw this, grinding finishes and can withdraw from.When upper slide 3 retreated to the back stop screw, driving lever 15 was pushed to a sawtooth, and the next one is waitd upon saw gumming and put in place.In order to prevent circular saw 10 moving influence reconditioning precision, stretch out two auricles 16 at lower skateboard 2 right-hand members, on two auricles 16, install and regulate damping sheet 17, damping sheet is equipped with damping screw 28 respectively on two tops, regulate the two sides (figure does not show) that the damping screw leans saw blade 10, make it guarantee that saw blade can rotate, do not vibrate again.

Because these gear grinding machines are mounted on the Grinder bench directly reconditioning, saw blade does not just need to remove, as long as emery wheel is aimed at blade teeth, adjusts sawtooth sharpening yardstick and just can start shooting, and moves handle one and pushes away one and draw, and the saw blade reconditioning can be finished.This machined is simple, and is easy to use.Overcome the deficiency that manual file is repaiied, this machine is in light weight, and portable carrying is easy to loading and unloading, big factory no matter, and little factory and individual household with specialized lines of work can both be used.
