Description

The intersection-line cutting machine checkout gear

Technical field

The utility model relates to a kind of checkout gear, especially relates to a kind of intersection-line cutting machine checkout gear.

Background technology

Intersection-line cutting machine in the cutting industry of pipeline by extensive utilization; Especially the technology mode of plasma, flame cutting be pipe support steel construction producer acceptance in manufacturing and the construction steel structure of industry conveyance conduits such as a lot of petrochemical industries, natural gas, boiler, pressure vessel, hydraulic and electric engineering.Intersection-line cutting machine is in cutting process; All there is different difference in the roundness that is cut steel pipe; Usually use displacement transducer to detect height, and with the numerical value that detects and the control system communication of intersection, output correlation signal; Make executing agency keep cutting-height, reach the purpose of roundness adjustment.

At present, intersection-line cutting machine is big to the roundness deviation, and usual practice is to adopt the displacement tracking mode; Be exactly that the roundness deviate of pipeline is passed through the sensor sample input system, in cutting process, the adjustment cutting-height; But find to have in actual use to have several problems, because the signal employing is analog form, the deviation of signal of sampling is bigger; And be subject to the interference of external signal, and having shown has unsettled aspect, and cutting process is prone to the situation of shake; Process is apparent in view in the plasma cutting, causes cutting the phenomenon that there is ripple glaze on the surface.Sensor lost efficacy in the environment of Metal Cutting easily, and the cost and the difficulty of maintenance are big.

Summary of the invention

The utility model technical problem to be solved provides a kind of good stability, the interference-free and low intersection-line cutting machine checkout gear of maintenance cost.

In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: this intersection-line cutting machine checkout gear; Comprise the inductor mount pad; The below of said inductor mount pad is equipped with cutting pipes to be detected; Be respectively arranged with position sensor one and position sensor two above the inductor mount pad, said position sensor one and position sensor two following respectively is provided with a plastic spacer, and the below of plastic spacer respectively is provided with one and is used to provide position sensor whether to send the guide pillar of altitude signal.

Moving in order to prevent the position sensor string, further, be fixedly connected through hold-down nut between said position sensor one and position sensor two and the inductor mount pad.

In order to transmit signal smoothly, more further, said plastic spacer is provided with the location sensitive face.

In order to make guide pillar recover rational position, come the motion of secondary guide, further, said guide pillar is provided with spring.

Compared with prior art; The usefulness of the utility model is: this intersection-line cutting machine checkout gear signal shows stable; Respond well, percent of automatization improves a lot, has surpassed client's re-set target; And realized easy to operate, dependable performance, do not had other bad phenomenon, satisfied the requirement of tubing cutting.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the utility model front view;

Fig. 2 is the cutaway view of A-A among Fig. 1.

Among the figure: 1, position sensor one; 2, position sensor two; 3, hold-down nut; 4, plastic spacer; 5, location sensitive face; 6, spring; 7, guide pillar; 8, inductor mount pad; 9, cutting pipes.

The specific embodiment:

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in detail:

Fig. 1, a kind of intersection-line cutting machine checkout gear shown in Figure 2; Comprise with exotic material and process inductor mount pad 8; The below of said inductor mount pad 8 is equipped with cutting pipes to be detected 9; Be respectively arranged with position sensor 1 and position sensor 22 above the inductor mount pad 8, said position sensor 1 and position sensor 22 following respectively is provided with a plastic spacer 4, and plastic spacer 4 is provided with location sensitive face 5; Can transmit signal smoothly, and plastic spacer 4 guarantees the correct induction and the service life of position sensor sensitive surface; Said plastic spacer; The below of plastic spacer 4 respectively is provided with one and is used to the guide pillar 7 that provides position sensor whether to send altitude signal; Said guide pillar 7 is provided with spring 6, makes guide pillar 7 can recover rational position, comes the motion of secondary guide; Moving in order to prevent the position sensor string, be fixedly connected through hold-down nut 3 between said position sensor 1 and position sensor 22 and the inductor mount pad 8.

Particularly, said position sensor 1 is used to respond to minimum cutting-height, and position sensor 22 is used for the highest cutting-height of induction; When two position sensors are sensed signal simultaneously; Position sensor two sends and is lower than the highest cutting-height signal, and the control system receives this signal, sends and cuts the low signal instruction; Cutting torch is promoted, realized the processing procedure of the low testing process of the mistake in the cutting process.When two position sensors are responded to less than signal simultaneously; Position sensor 1 sends and is higher than the highest cutting-height signal, and the control system receives this signal, sends the too high signal instruction of cutting; Cutting torch is reduced, realized the processing procedure of the too high testing process in the cutting process; Only receive signal at position sensor 1 in a word, when position sensor 22 did not detect signal, the system validation cutting-height was reasonable.

This intersection-line cutting machine checkout gear signal shows stable, and is respond well, and percent of automatization improves a lot, has surpassed client's re-set target, and realized easy to operate, dependable performance, do not have other bad phenomenon, satisfies the requirement of tubing cutting.

It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
