Technical field
The utility model relates to a kind of machining utility appliance, particularly relates to a kind of mechanical component workhardness pick-up unit.
Background technology
Machining refers to the process changed the physical dimension of workpiece or performance by a kind of plant equipment.Cut and pressure processing can be divided into by the difference on processing mode.But because the hardness of steel is different, the part quality after processing is affected to some extent, therefore, need a kind of portable and efficiently New Hardness Testing Device it is detected, to ensure the quality of product.
Utility model content
The purpose of this utility model is just to provide a kind of mechanical component workhardness pick-up unit to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises detection groove, detection head, screw rod, breast wheel, driving wheel, motor, displacement transducer and alarm, described detection head is installed on the side of described detection groove, described detection head is connected by described screw rod with between institute displacement sensors, the side of described screw rod is connected with described driving wheel is meshing by described breast wheel, described driving wheel is connected with the rotating shaft of described motor, and the signal output part of institute's displacement sensors is connected with described alarm.
Particularly, described alarm is made up of to the 4th triode, switch, battery and loudspeaker to the 7th resistance, electric capacity, the first triode the first resistance.
The beneficial effects of the utility model are:
The utility model is a kind of mechanical component workhardness pick-up unit, compared with prior art, the utility model adopts physical construction and electronic component composition rigidity detection device, adopts electronic component few, with low cost, volume is little, easily carries, and utilizes electronic component to form design, accuracy of detection can be improved, easy to use, detect quick, there is the value applied.
Accompanying drawing explanation
Fig. 1 is structure cut-open view of the present utility model;
Fig. 2 is the circuit structure schematic diagram of alarm in Fig. 1.
In figure: 1-detects groove, 2-detection head, 3-screw rod, 4-breast wheel, 5-driving wheel, 6-motor, 7-displacement transducer, 8-alarm.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises detection groove 1, detection head 2, screw rod 3, breast wheel 4, driving wheel 5, motor 6, displacement transducer 7 and alarm 8, detection head 2 is installed on the side detecting groove 1, be connected by screw rod 3 between detection head 2 with displacement transducer 7, the side of screw rod 3 is connected with driving wheel 5 is meshing by breast wheel 4, driving wheel 5 is connected with the rotating shaft of motor 6, and the signal output part of displacement transducer 7 is connected with alarm 8.
As shown in Figure 2: alarm is made up of to the 4th triode, switch, battery and loudspeaker to the 7th resistance, electric capacity, the first triode the first resistance.
Mechanical component are placed as detected in groove 1, starter motor 6 makes detection head 2 be pushed against by part, observing detection head 2 thrusts in the signal input alarm 8 of degree bound site displacement sensor, as hardness reaches requirement, then the first triode VT1 ends, the collector voltage of the first triode VT1 rises, second triode VT2 conducting, the collector voltage of the second triode VT2 declines, by the 3rd triode VT3, the alarm circuit for generating of the composition such as the 4th triode VT4 and loudspeaker BL disconnects, loudspeaker BL would not report to the police, as hardness does not reach requirement, first triode VT1 conducting, the collector voltage of the first triode VT1 declines, second triode VT2 ends, the collector voltage of the second triode VT2 rises, by the 3rd triode VT3, the alarm circuit for generating conducting of the composition such as the 4th triode VT4 and loudspeaker BL, loudspeaker BL reports to the police, hardness does not reach requirement.The resistance changing the 8th resistance R8 can change the hardness requirement of setting.
Component parameter of the present utility model is selected as follows:
First resistance R1 is 70 Ω, the second resistance R2 is 200 Ω, the 3rd resistance R3 is 300 Ω, the 4th resistance R4 is 1k Ω, the 5th resistance R5 is 2k Ω, the 6th resistance R6 to the 8th resistance R8 be 100 Ω, the first triode VT1 to the 3rd triode VT3 be PNP type triode, the 4th triode VT4 is NPN type triode, electric capacity C is 300uf, battery E is 3V.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
