Abstract
The invention relates to the technical field of machine safety protection, in particular to an interlocking protection device of a manual grinding machine. The interlocking protection device of the manual grinding machine comprises a motor, a grinding plate, a grinding plate protection hood and a base. The grinding plate is fixed in the grinding plate protection hood through a rotary shaft. The motor drives the grinding plate to rotate. The grinding plate protection hood and the motor are both fixed to the based. An interlocking protection hood is hinged to the grinding plate protection hood or the base. When rotating, the interlocking protection hood can be located in the position between an operator and the grinding plate or the position where the operator can observe the position of the grinding plate. By arranging the interlocking protection hood, the operator can be effectively prevented from being injured by a broken grinding plate when the interlocking protection hood is located in the position between the operator and the grinding plate, the operator can observe the position of the grinding plate only by rotating the interlocking protection hood, and operation is quite convenient. Meanwhile, the structure is simple, the interlocking protection device can be additionally installed on an existing grinding machine quite conveniently, so that the interlocking protection device is convenient to apply and popularize.
Description
Technical field
The present invention relates to machine security guard technology field, particularly to a kind of hand operated grinding wheel machine interlocking preventer.
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；The machining such as grooving, chamfering.But owing to its design specification and safety standard requirement are insufficient, the potential safety hazard of abrasive machine itself is more, adds that the safety consciousness of operator and Safety skill are weak, cause the event of hurting sb.'s feelings to happen occasionally.Found by statistics, hurting sb.'s feelings of abrasive machine is primarily due to what grinding wheel explosion caused, the grinding wheel of currently the majority is addition bonding agent in abrasive material, the porous body made through pressed compact, dry and roasting, workmanship difference is bigger, during use, firmly it is difficult to ensure that equilibrium, it is easy to cause grinding wheel explosion to be hurted sb.'s feelings because strength is excessive.
Summary of the invention
It is an object of the invention to provide a kind of hand operated grinding wheel machine interlocking preventer, it is to avoid grinding wheel explosion is hurted sb.'s feelings, and improves the safety that hand operated grinding wheel machine uses.
For realizing object above, the technical solution used in the present invention is: a kind of hand operated grinding wheel machine interlocking preventer, including motor, grinding wheel, grinding wheel protective cover and base, grinding wheel is fixed in grinding wheel protective cover by rotating shaft, motor drives grinding wheel to rotate, grinding wheel protective cover and motor are each attached on base, being hinged with interlocking protective cover on grinding wheel protective cover or base, interlocking protective cover can be located on the position between operator and grinding wheel when rotating or is positioned at and do not blocks operator and observe on the position of grinding wheel.
Compared with prior art; there is techniques below effect in the present invention: by arranging interlocking protective cover; operator can be effectively protected to avoid the grinding wheel being broken to hurt time on interlocking protective cover position between operator and grinding wheel; have only to when operator need and observe grinding wheel position rotate interlocking protective cover; operate very convenient; this simple in construction simultaneously, it is possible to be attached to easily on existing abrasive machine, it is simple to promote practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the three-dimensional structure diagram of the present invention, wherein eliminates motor, contact switch.
Detailed description of the invention
Below in conjunction with 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 interlocking preventer, including motor 10, grinding wheel 20, grinding wheel protective cover 30 and base 40, grinding wheel 20 is fixed in grinding wheel protective cover 30 by rotating shaft, motor 10 drives grinding wheel 20 to rotate, grinding wheel protective cover 30 and motor 10 are each attached on base 40, being hinged with interlocking protective cover 50 on grinding wheel protective cover 30 or base 40, interlocking protective cover 50 can be located on the position between operator and grinding wheel 20 when rotating or is positioned at and do not blocks operator and observe on the position of grinding wheel 20.By arranging interlocking protective cover 50; the grinding wheel 20 that can effectively protect operator to avoid being broken time on the interlocking protective cover 50 position between operator and grinding wheel 20 hurts; have only to when operator need and observe grinding wheel 20 position rotate interlocking protective cover 50; operate very convenient; this simple in construction simultaneously; can be attached to easily on existing abrasive machine, it is simple to promote practicality.
Operator are when operation, sometimes can forget to turn on the position between operator and grinding wheel 20 by interlocking protective cover 50, so the most dangerous after startup abrasive machine, generation in order to avoid this situation, in the present embodiment preferably, being provided with trigger element between described interlocking protective cover 50 and grinding wheel protective cover 30 or base 40, time on the interlocking protective cover 50 position between operator and grinding wheel 20, trigger element action allows motor 10 to be energized.After trigger element action, it is allowed in the case of motor 10 energising, as long as operator open the switch of motor 10, motor 10 will start；If trigger element is not operating, now motor 10 does not allow energising, even if operator open the switch of motor 10, motor 10 still can not start.
The structure of interlocking protective cover 50 has a variety of, as long as protective action can be played, the present embodiment provides a kind of preferred embodiment, described interlocking protective cover 50 is hinged on protective hood of grinding wheel 30, interlocking protective cover 50 includes the fanning strip 51 that two panels is arranged in parallel and the arc 52 connecting two fanning strips 51, the plate face of two fanning strips 51 is parallel to the plane at grinding wheel 20 place, arc 52 is perpendicular to the plate face of fanning strip 51, and the lower end of arc 52 is against trigger element action time on the base 40 it.The interlocking protective cover 50 being made up of fanning strip 51 and arc 52, structure is very simple effectively, also can easily be hinged on protective hood of grinding wheel 30 simultaneously.
Similarly, the structure of trigger element has a variety of, in the present embodiment preferably, bar hole 511 and contact switch 512 is offered on one of them fanning strip 51, the length direction of bar hole 511 is the center of circle and the center of rotation coincidence of interlocking protective cover 50 of arc and this arc, being fixedly installed projection 31 on grinding wheel protective cover 30 to pass from bar hole 511, the lower end of arc 52 is resisted against on contact switch 512 permission motor 10 against projection time on the base 40 it 31 and is energized.In position shown in Fig. 1, projection 31 and contact switch 512 lean, now, it is allowed to motor 10 is energized, it will be seen that interlocking protective cover 50 now can protect operator well from figure；When interlocking protective cover 50 is rotated up by operator, projection 31 and contact switch 512 are separated, and do not allow motor 10 to be energized, even if now operator open the on and off switch of motor 10, can not start motor 10, and protected effect is the best.
