The device comprises a vibration signal receiving and electrical signal converting circuit, a signal amplifying circuit, a one-chip microcomputer control circuit and an RS485 communication interface circuit, output signals of the vibration signal receiving and electrical signal converting circuit are transmitted to the one-chip microcomputer control circuit through the signal amplifying circuit, and output signals of the one-chip microcomputer control circuit are controlled and sent to the RS485 communication interface circuit. In the device, a piezoceramic transducer HTD arranged on the upper end of a vibration bench is used for collecting vibration signals, a block-building machine is started and vibrated, when the vibration frequency reaches a certain scope, vibration signals are received and electrical signals are converted, then the signals are amplified by the signal amplification circuit and transmitted to the one-chip microcomputer, and the signals are sent to a PC after being judged by the one-chip microcomputer, the PC is used for judging whether the vibration bench is qualified or not, and ex-factory pass rate of the block-building machine is greatly enhanced.

Description

Building block machine vibration proving installation

Technical field

The utility model relates to a kind of proving installation, particularly be a kind of building block machine vibration proving installation.

Background technology

The inner principal organ of building block machine is a vibrating device, and the vibration frequency quality of this vibrating device directly affects the quality of building block machine made brick, so the building block machine need be answered the bob-weight test when dispatching from the factory after, just dispatch from the factory.

The utility model content

The purpose of the utility model is to provide a kind of building block machine vibration proving installation of simple in structure, the ex factory pass rate that can improve the building block machine.

The utility model solves the technical scheme that its technical matters adopted: building block machine vibration proving installation; Including vibration signal receives and electrical signal conversion circuit, signal amplification circuit, single chip machine controlling circuit and RS485 communication interface circuit; Said vibration signal receives and the output signal of electrical signal conversion circuit transfers to single chip machine controlling circuit through signal amplification circuit, and the output signal controlling of said single chip machine controlling circuit is sent to the RS485 communication interface circuit.

Preferably, said vibration signal receives and is connected capacitor C1 with the electrical signal conversion circuit by the output terminal that is installed in the piezoceramic transducer HTD on the shaking table and potentiometer RP constitutes.

Preferably, said signal amplification circuit adopts the direct manifold type amplifying circuit of two-stage that triode VT1, VT2 form.

Preferably, said RS485 communication interface circuit is connected to the COM end of RS485 communication interface through SN75176 communication interface chip IC2.

Through adopting above-mentioned technical scheme, the beneficial effect of the utility model is: the utility model adopts the piezoceramic transducer HTD that is installed in the shaking table upper end to gather vibration signal, opens the building block machine and vibrates by it; When its vibration frequency reaches certain limit; After vibration signal reception and electrical signal conversion, signal amplification circuit amplify, transfer to single-chip microcomputer, after single-chip microcomputer is judged, be sent to PC; Judge by PC whether shaking table is qualified, improve the ex factory pass rate of building block machine greatly.
