Description
Technical field
The present invention relates to machine security protection technology field, more particularly to a kind of hand operated grinding wheel machine interlocking protector.
Background technology
Hand operated grinding wheel machine is easy to operate, and use cost is low, is widely used in cutting tubing, round steel class;Grooving, chamfering etc. are cut
Processing.But because its design specification and safety standard requirement are insufficient, the potential safety hazard of abrasive machine in itself is more, plus operator
The awareness of safety and Safety skill of member is weak, causes the event of hurting sb.'s feelings to happen occasionally.Found by counting, hurting sb.'s feelings for abrasive machine is main
Reason is due to that the grinding wheel of currently the majority is that bonding agent is added in abrasive material caused by grinding wheel bursts, and by pressed compact, is done
Dry and roasting and manufactured porous body, workmanship difference are larger, in use, being firmly difficult to ensure that equilibrium, it is easy to because power
Measure it is excessive cause grinding wheel explosion hurt sb.'s feelings.
The content of the invention
It is an object of the invention to provide a kind of hand operated grinding wheel machine to interlock protector, avoids grinding wheel explosion from hurting sb.'s feelings, carries
The security that height manual abrasive machine uses.
To realize object above, the technical solution adopted by the present invention is:A kind of hand operated grinding wheel machine interlocks protector, including
Motor, grinding wheel, grinding wheel protective cover and base, grinding wheel are fixed in grinding wheel protective cover by rotating shaft, motor driving
Grinding wheel is rotated, and grinding wheel protective cover and motor are each attached on base, and connection is hinged with grinding wheel protective cover or base
Protective cover is locked, on the position that interlocking protective cover can be between operating personnel and grinding wheel when rotating or positioned at not blocking operation
On the position of personal observations' grinding wheel.
Compared with prior art, there is following technique effect in the present invention:Protective cover is interlocked by setting, interlocking protective cover position
The grinding wheel that can effectively protect operating personnel to avoid being broken when on the position between operating personnel and grinding wheel injures
Arrive, only need to rotate interlocking protective cover when operating personnel need to observe grinding wheel position, operate very convenient,
This is simple in construction simultaneously, can easily be attached on existing abrasive machine, is easy to promote practicality.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the three-dimensional structure diagram of the present invention, wherein eliminating motor, contact switch.
Embodiment
With reference to Fig. 1 to Fig. 2, the present invention is described in further detail.
Refering to Fig. 1, Fig. 2, a kind of hand operated grinding wheel machine interlocks protector, including the protection of motor 10, grinding wheel 20, grinding wheel
Cover 30 and base 40, grinding wheel 20 are fixed in grinding wheel protective cover 30 by rotating shaft, and motor 10 drives grinding wheel 20 to rotate,
Grinding wheel protective cover 30 and motor 10 are each attached on base 40, and interlocking is hinged on grinding wheel protective cover 30 or base 40
Protective cover 50, can be on the position between operating personnel and grinding wheel 20 or positioned at not blocking when interlocking protective cover 50 rotates
Operating personnel are observed on the position of grinding wheel 20.By set interlock protective cover 50, interlocking protective cover 50 be located at operating personnel with
The grinding wheel 20 that can effectively protect operating personnel to avoid being broken when on the position between grinding wheel 20 is hurt, and works as operation
Personnel need only to need to rotate interlocking protective cover 50 when observing 20 position of grinding wheel, operate very convenient, simultaneously
This is simple in construction, can easily be attached on existing abrasive machine, is easy to promote practicality.
Operating personnel in operation, can sometimes forget will interlocking protective cover 50 turn to operating personnel and grinding wheel 20 it
Between position on, so start it is still dangerous after abrasive machine, it is excellent in the present embodiment the occurrence of in order to avoid this
Selection of land, trigger element, interlocking protection are provided between described interlocking protective cover 50 and grinding wheel protective cover 30 or base 40
Trigger element action allows motor 10 to be powered when on 50 position between operating personnel and grinding wheel 20 of cover.Trigger element moves
After work, it is allowed to which in the case that motor 10 is powered, as long as operating personnel open the switch of motor 10, motor 10 will start;If
Trigger element is not operating, and now motor 10 does not allow to be powered, even if operating personnel open the switch of motor 10, motor 10 is still
It can not start.
The structure of interlocking protective cover 50 has many kinds, as long as protective action can be played, one is provided in the present embodiment
Kind preferred embodiment, described interlocking protective cover 50 are hinged on protective hood of grinding wheel 30, and interlocking protective cover 50 includes two panels
The fanning strip 51 of parallel arrangement and the arc 52 for connecting two fanning strips 51, the plate face of two fanning strips 51 is parallel to emery wheel
Plane where piece 20, arc 52 perpendicular to fanning strip 51 plate face, the lower end of arc 52 against on the base 40 it when touch
Bill metaaction.The interlocking protective cover 50 being made up of fanning strip 51 and arc 52, structure is very easy and effective, while also can
Easily it is hinged on protective hood of grinding wheel 30.
Similarly, the structure of trigger element has a many kinds, is opened up on one of fanning strip 51 in the present embodiment preferably
There are bar hole 511 and contact switch 512, the length direction of bar hole 511 is the center of circle of arc and the arc and interlocking protective cover
50 center of rotation overlaps, and be fixedly installed projection 31 on grinding wheel protective cover 30 passes through from bar hole 511, arc 52
Lower end against on the base 40 it when projection 31 be resisted against on contact switch 512 allow motor 10 be powered.In position shown in Fig. 1,
Projection 31 and contact switch 512 lean, now, it is allowed to which motor 10 is powered, it will be seen that interlocking now is prevented from figure
Shield 50 can protect operating personnel well;When operating personnel, which will interlock protective cover 50, to be rotated up, projection 31 and contact
Switch 512 is separated, and does not allow motor 10 to be powered, even if now operating personnel open the power switch of motor 10, can not open
Dynamic motor 10, protecting effect are very good.
