The invention has the advantages of simple structure, convenient operation, reliable operation, and the like.
Description
Technical field
The present invention relates to the accessory on a kind of compound saw, be specifically related to a kind of locking device that when compound saw switches to the different operating state, can effectively play the compound saw locking effect, simple in structure, reliable operation.
Background technology
At present, compound saw is widely used in fields such as machine-building as a kind of electric tool commonly used.Compound saw can switch to diagonal cutting saw and two kinds of duties of bench saw respectively.Compound saw in use requires below must satisfying: when switching to the bench saw duty, and during the operation bench saw, the diagonal cutting saw akinesia; When switching to the diagonal cutting saw duty, during the operation diagonal cutting saw, the bench saw akinesia.This just need install locking device on compound saw.But existing locking device structure is complicated, parts are many, complex operation step, locking effect are unreliable, diagonal cutting saw misoperation when bench saw work often occurring, and the phenomenon of bench saw misoperation caused injury to personnel easily when perhaps diagonal cutting saw was worked.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the present invention provides a kind of locking device of simple in structure, easy to operate, the reliable compound saw of locking effect.
Technical scheme: for solving the problems of the technologies described above; The locking device of a kind of compound saw of the present invention comprises latch, locking connecting rod, body and bearing, and said body is installed on the bearing; Said latch passes bearing and inserts in the body; Said locking connecting rod one end is installed on the body, and the locking connecting rod other end is equipped with the contacted bearing of electric machine spacing plate with compound saw, and the locking connecting rod back side is connected with extension spring on being installed in body.
Said locking connecting rod be shaped as down " 3 " shape, the locking connecting rod is provided with breach, locking connecting rod middle part is provided with bar hole, is provided with the screw that is installed on the body in the said bar hole.Extract latch from body, when lifting body or pressing down body, bar hole can move along screw.
Said latch be provided with can with first cannelure and second cannelure of locking connecting rod snap-fit, first cannelure and second cannelure are divided into latch leading portion, latch stage casing and latch latter end with latch.When the duty that is in bench saw, when latch inserted body, the breach of locking connecting rod was stuck in first arc groove of latch, and body is fixed, and body can not rise or descend, the security when effectively guaranteeing the bench saw duty.
Said bearing is provided with through hole, and latch passes this through hole and inserts in the body, and this through hole one side is provided with circular hole, and steel ball and stage clip are installed in the circular hole.When the latch leading portion was extracted in body, steel ball slipped under the active force of stage clip in second arc groove of latch.At this moment; Because latch breaks away from body, so can body lifted or press down, the locking connecting rod be followed the electric machine spacing plate and is moved together under the effect of extension spring power; In the process that body lifts or presses down, electric machine spacing plate bottom is against on the bearing of locking connecting rod all the time.In the diagonal cutting saw course of work, carry out cutting movement, bench saw akinesia this moment through lifting or press down body drive saw blade.
Beneficial effect: the locking device of compound saw of the present invention; The effect that locks through locking connecting rod and latch is locked to compound saw; Can access effective location when making compound saw switch to the different operating state, have advantages such as simple in structure, easy to operate, reliable operation.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
Shown in Fig. 1-4; The locking device of compound saw of the present invention comprises latch 1, locking connecting rod 2, body 3 and bearing 4; Body 3 is installed on the bearing 4, and latch 1 passes bearing 4 and inserts in the body 3, and locking connecting rod 2 one ends are installed on the body 3; Locking connecting rod 2 other ends are equipped with the electric machine spacing plate 5 contacted bearings 6 with compound saw, and locking connecting rod 2 back sides are connected with extension spring 14 on being installed in body.Locking connecting rod 2 be shaped as down " 3 " shape, locking connecting rod 2 is provided with breach 21, locks connecting rod 2 middle parts and is provided with bar hole 22, is provided with the screw 23 that is installed on the body 3 in the bar hole 22.Latch 1 is provided with and can latch 1 be divided into latch leading portion 13, latch stage casing and latch latter end with first cannelure 11 of locking connecting rod 2 snap-fit and second cannelure, 12, the first cannelures 11 and second cannelure 12.Bearing 4 is provided with through hole 7, and latch 1 passes this through hole 7 and inserts in the body 3, and these through hole 7 one sides are provided with circular hole 8, and steel ball 9 and stage clip 10 are installed in the circular hole 8.
The locking device of compound saw of the present invention in use, and is as shown in Figure 2, when switching to the bench saw duty, latch 1 passed bearing 4 insert in the body 3, and the breach 21 of locking connecting rod 2 is stuck in first arc groove 13 of latch 1, and body 3 is fixed on the bearing 4; When saw blade was in extreme lower position, the bottom of electric machine spacing plate 5 was against on the bearing 6, was installed in the bottom position that screw 23 on the body 3 is in strip hole 22.When adjusting the motor height through handling knob and then regulating the saw blade height; Rotation along with motor; Bearing 6 motions of locking on the connecting rod 2 are being supported in 5 motions of electric machine spacing plate simultaneously; The strip hole 22 that makes locking connecting rod 2 is along screw 23 runnings that are installed on the body 3, and the extension spring 14 at locking connecting rod 2 back sides is elongated.As shown in Figure 3, when motor turns to saw blade when being in the extreme higher position, the top of electric machine spacing plate 5 is against on the bearing 6 of locking connecting rod 2, and screw 23 is in the apical position of strip hole 22.In the adjustment process of saw blade height, during the operation bench saw, the diagonal cutting saw akinesia.
As shown in Figure 4, when switching to the diagonal cutting saw duty, latch 1 to be extracted in body 3, the steel ball 9 on the bearing 4 in the circular hole 8 slips under the active force of stage clip 10 in second arc groove 12 of latch 1.At this moment; Because latch 1 breaks away from body 3, so when body 3 lifted, locking connecting rod 2 was followed electric machine spacing plate 5 and moved together under the effect of extension spring 14 power; In the process that body 3 lifts or presses down, electric machine spacing plate 5 bottoms are against on the bearing 6 of locking connecting rod 2 all the time.In the diagonal cutting saw course of work, carry out cutting movement, bench saw akinesia this moment through lifting or press down body 3 drive saw blades.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
