Abstract
The utility model discloses an abrasive wheel cutter which is suitable for cutting metal samples in a laboratory. The utility model comprises an engine base, a cradle hinged with the engine base, an abrasive wheel component installed on the cradle, and a component for clamping work piece installed on the engine base. The utility model is characterized in that the component for clamping work piece is a hydraulic clamping device, and a pair of normally open contacts which control the contactor of the component for clamping work piece are connected in series with a control circuit which controls an abrasive wheel driving motor; a touch switch which controls the abrasive wheel is arranged on the engine base which is below the frontal end of the cradle, and the cradle can bear the gravitation; the frontal end of the cradle is bunted to the touch switch. The abrasive wheel driving motor can only be started when a sample bar is clamped by the hydraulic clamping device in order to prevent the injury of operators who start the machine without clamping the sample bar; for preventing the danger of electric shock caused by the operators' wet hands, the touch switch of the abrasive wheel driving motor is controlled by the cradle. Compared with the prior art, the utility model has the advantage of getting rid of hidden dangers.
Description
Technical field
The utility model relates to a kind of cutting machine, and especially a kind of abrasive wheel cutting machine that is applicable at laboratory cutting metal sample belongs to the laboratory equipment technical field.
Background technology
Iron and steel enterprise is preparation spark spectrum instrument test button, particularly prepare hard alloy steel, pig iron spoken parts in traditional operas specimen preparation, usually need with abrasive wheel cutting machine club-shaped material to be cut into the sheet body earlier, make the sheet sample that is suitable for as spectrum analysis by grinding then.In use there are the following problems to be used for the abrasive wheel cutting machine of this purposes now:
1, in the process of clamping sample or under the not clamped situation of sample, the easy false touch switch of operator and cause personal injury or device damage;
2, the emery wheel starting switch is installed on the operating grip, and the sample bar usually just from water cooling back take out, so operator's wet hand touches switch Danger Electric shock risk is arranged;
Motor can rotate when 3, changing grinding wheel, and the operator need grip grinding wheel with a hand, and the another hand uses instruments such as wrench, and is careless slightly, will injure people's hand.
Summary of the invention
The technical problem that will solve of the present utility model is: the existing misoperation and the potential safety hazard of easily leaking electricity in using at above existing abrasive wheel cutting machine propose a kind of abrasive wheel cutting machine with foolproof apparatus.
In order to solve above technical problem, the abrasive wheel cutting machine that the utlity model has foolproof apparatus comprises support, with the hinged reel cage of support, be installed in emery wheel parts on the reel cage, be placed in the workpiece clamping part on the support, its improvements are: described workpiece clamping part is a hydraulic clamp, and a pair of normally open contact of controlling the contactor of described clamping device is connected in the control circuit of control emery wheel drive motors.
Further improvement of the utility model is, the touch switch of control emery wheel running is installed on the support below the front end of reel cage, described reel cage gravitate, and front end is resisted against on the touch switch.
Before carrying out cutting processing, because gravitate, the reel cage front end is resisted against on the touch switch, so grinding wheel drive mitor does not change.During work, start earlier hydraulic pump motor, by hydraulic clamp that the test rod feed collet is tight, and then the handgrip that presses down reel cage carries out cutting processing.
Be not difficult to find out that in above process, only under hydraulic pump motor work, hydraulic clamp condition that the test rod feed collet is tight, the emery wheel drive motors just might rotate, therefore can prevent from not clamp and the maloperation personnel that cause injure.In addition, the utility model is controlled the grinding wheel drive mitor contact switch by reel cage, has avoided wet hand to touch the Danger Electric shock risk that switch causes.Obviously, compared with prior art, the utility model has been eliminated injury hidden danger, and is fool proof reliable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the circuit theory diagrams of Fig. 1 embodiment.
The specific embodiment
Shown in Fig. 1～2, the abrasive wheel cutting machine with foolproof apparatus of present embodiment comprises support 2, reel cage 4, emery wheel parts 6, hydraulic system 1, clamp mechanism 13.Reel cage 4 and support are 2 hinged, emery wheel parts 6 are installed on the reel cage 4, clamp mechanism 13 is connected with support 2, hydraulic system 1 is installed in the support 2, and the push rod of its hydraulic cylinder 14 is connected with lever 12 1 ends of clamp mechanism 13; The touch switch 3 of control emery wheel drive motors is arranged on the front lower place of reel cage 4, is connected with support 2; Emery wheel parts 6 contain latch 7, grinding wheel spindle 10 and the bearing block 9 of grinding wheel spindle 10 are installed, and are shaped on blind hole and the through hole 1 suitable with latch 7 on grinding wheel spindle 10 and the bearing block 9 respectively.
The present embodiment electric control theory as shown in Figure 3, contactor YDJ comprising control hydraulic pump motor YD1, this contactor YDJ is by the switching of button 1QA and 1TA control CJ1, the a pair of normally open contact of contactor YDJ is connected in the contactor QDJ control circuit of control emery wheel drive motors QD2, the break-make of contactor QDJ control CJ2.This shows that when hydraulic system was not worked, emery wheel drive motors QD2 was in blocking.
The utility model is before making cutting processing, the front end of reel cage 4 is resisted against on the contact of touch switch 3, elder generation's primer fluid pressing system 1 is tight with the test rod feed collet during work, press down the handgrip 11 of reel cage 4 then, leave the contact (being the K2 closure) of touch switch 3 when reel cage 4 after, the motor QD2 of emery wheel parts is activated, thereby can carry out cutting processing.Because of staff does not touch switch 3, so can not shocked by electricity.
When changing grinding wheel 8, by bearing block 9 latch 7 is injected in the blind hole of grinding wheel spindle 10, so not only easy to operate, and can not injure staff.
Be understood that operation rational in infrastructure, easy that present embodiment has, safe and reliable advantage.
In addition, for further improving security performance, can also increase pressure sensor in the present embodiment hydraulic system, the output of this pressure sensor is connected with the grinding wheel drive mitor control circuit.Can guarantee that like this motor of emery wheel parts when workpiece is clamped can work.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
