Description
Technical field
The invention belongs to machine tool technology field, specifically, the present invention relates to a kind of being arranged between lathe two collapsible forms for avoiding because the change of collapsible form distance causes the lathe spacing safeguard protection bar that lathe damages and personnel injure.
Background technology
In lathe, the distance between two collapsible forms constantly changes, reduces, and often makes the structure in this distance range be subject to unnecessary damage; Sometimes even the accidents such as personal injury are caused.For example in the forming machines such as punching press, install between portable plate and working plate, debug molding equipment etc., particularly to the on-the-spot repair process of molding equipment, because man-made failure operation or machine failure cause the damage of equipment, even personal injury.Because this type of machinery uses extensively aborning, accident occurrence frequency is very high, very harmful.
In the prior art, various machinery adopts photoelectric technology etc. to detect the abnormal object entered in operation interval, and as found unknown object, then power-off is immediately shut down.Also the method adopting fixing portable plate is had.In forming machine, normal employing is shut down and machine motor power-off, carries out the debugging repair work of molding equipment afterwards again; But sometimes in order to debug, the convenience of repair, more often have to adopt and to shut down but machine motor power supply works under not closing situation.
Adopt the protection of photoelectric technology detection foreign matter safety law, be carry out in the course of the work, in the effective coverage of photodetection, have effect, unrestricted outside region; And the inertia can not preventing template moves the infringement caused.Adopt fixing portable plate Protection Code operator usually to feel trouble, and violation operation, and normally work often can forget at lathe and the fixed constraint of portable plate is removed and cause lathe to damage.
In order to install, debug or repair molding equipment in forming machine; adopt and to shut down and machine motor power-off method is the course of work of specification; but because many forming machine controlling organizations are malfunctioning, arrestment mechanism is aging; portable plate, works the mischief to movable workbench due to reasons such as deadweights.Some operators are in order to the debugging of molding equipment is convenient and repair process facilitates; employing is shut down but machine motor power supply works under not closing situation; though this violates normal operating procedure; but this phenomenon is very general in actual production; in this case, easily there is the malfunctioning or maloperation of controlling organization especially and work the mischief.
For the deficiency that prior art exists, the present invention is proposed.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the object of this invention is to provide under one is applicable to the multiple condition of production, while guaranteeing operator's safety, also suitable protection being made to lathe, unlikelyly to damage; And structure simple, quick and easy to use, reliable lathe spacing safeguard protection bar.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes as follows:
A kind of lathe spacing safeguard protection bar, between two collapsible forms being arranged on lathe, comprise a body of rod, one end of the body of rod extends internally and is formed with hole type cavity, is provided with a spring in cavity, and the top of spring is provided with slide bar, and the top of slide bar is stretched out outside cavity; The outer wall of the body of rod is provided with a collection hole be communicated with cavity, and gather the signal pickup assembly being provided with in hole and gathering slide bar motor message, signal pickup assembly is connected with machine tool electric force control device.
The top of the described body of rod is also provided with the cylinder that has centre bore, and cylinder and the body of rod are by bolt combination, and the diameter of centre bore is less than the diameter of body of rod inner chamber body; Described slide bar comprises column body and lower prop, and column body is mated with centre bore, and the diameter of lower prop mates with cavity; The column body of slide bar is passed centre bore and stretches out centre bore.
Described hole cavity bottom is formed with to the other end continuation extension of the body of rod installing hole penetrated, and the diameter of installing hole is less than cavity diameter, and installing hole is provided with backstay, and the end of backstay is provided with adjustment cushion block.
Described backstay is stairstepping, and comprise a cylinder head and a cylindrical bar, cylinder head is arranged in cavity, and cylindrical bar is arranged in installing hole.
Advantage of the present invention and good effect are:
The present invention, producing the successful brought in the manufacturing industry such as lathe, considerably reduces the damage of equipment and the injury of personnel.
Between two collapsible forms of lathe; place safeguard protection bar; when occurring that maloperation or Machine-Tool Control, brake component are malfunctioning; distance between two collapsible forms constantly reduces; oppress the slide bar in security activity bar gradually, slide bar moves that the signal of generation is collected passes to machine tool electric force control device, instant cutting-off machine power; lathe is produced and suddenly stops action, avoid lathe to damage.Stop the inertia of two collapsible forms to move by motion bar body, ensure the safety operation space between two collapsible forms; Wherein, the reset of slide bar is realized by the spring in security activity bar.
For example, on the injection molding machine of plastic in forming machine or punching press forcing press, in the installation of molding equipment, debugging or repair process, because electrical equipment control fault and people to occur for maloperation that molding equipment is damaged, personnel's injury accident is of common occurrence.If be furnished with the safeguard protection according to equipment of the present invention, the installation of molding equipment, debugging or repair process time be positioned between workbench and portable plate, then there will not be security incident.
The economic benefit of minimizing on enterprise of security incident has directly impact and significant lifting.
