Description
Technical field
The invention belongs to the machine tool technology field, specifically, the present invention relates to a kind of being arranged between two collapsible forms of lathe for avoiding because the collapsible form variable in distance causes that lathe damages and the lathe spacing safeguard protection bar of personnel's injury.
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 cause the accidents such as personal injury.For example in the forming machines such as punching press, between portable plate and working plate, install, debugging 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, the accident occurrence frequency is very high, very harmful.
In the prior art, various machinery employing photoelectric technologies etc. are surveyed the abnormal object entered in operation interval, and as found unknown object, outage is shut down immediately.The fixedly method of portable plate that adopts is also arranged.In forming machine, the normal employing shut down and the machine motor power-off, carries out afterwards the debugging repair work of molding equipment again; But sometimes in order to debug, the convenience of repair, more often have to adopt and shut down but the machine motor power supply is not closed under situation and worked.
Adopting photoelectric technology to survey the protection of foreign matter safety law, is to carry out in the course of the work, in the effective coverage of photodetection, effect is arranged, and zone is outer unrestricted; And the inertia that can not prevent template moves the infringement caused.Adopt fixedly portable plate Protection Code operator usually to feel trouble, and violation operation, and often can forget and the fixed constraint of portable plate be removed and caused the lathe damage in the lathe normal operation.
In forming machine in order to install, debugging or repair molding equipment; adopting shutdown and machine motor power-off method is the course of work of standard; but because many forming machine controlling organizations are malfunctioning, arrestment mechanism is aging; portable plate is former thereby to movable workbench due to deadweight etc., works the mischief.Some operators are for the debugging of molding equipment is convenient and the repair process is convenient; adopt to shut down but the machine motor power supply is not closed under situation and worked; though this violates the normal operating program; but this phenomenon is very general in actual production; in this case, the malfunctioning or maloperation of controlling organization easily occurs especially and work the mischief.
The deficiency existed for prior art, propose the present invention.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of being applicable under the multiple condition of production, when guaranteeing operator's safety, also lathe is made to suitable protection, unlikely damaging; And lathe spacing safeguard protection bar simple in structure, quick and easy to use, reliable.
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, be arranged between two collapsible forms of lathe, comprises a body of rod, and an end of the body of rod extends internally and is formed with hole die cavity body, is provided with a spring in cavity, and the top of spring is provided with slide bar, and stretch out outside cavity on the top of slide bar; The outer wall of the body of rod is provided with a collection hole be communicated with cavity, gathers in hole the signal pickup assembly that gathers the slide bar motor message is installed, and signal pickup assembly is connected with the machine tool electric force control device.
The top of the described body of rod also is provided with a cylinder with 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 cylinder and lower prop, upper cylinder and centre bore coupling, the diameter of lower prop and cavity coupling; The upper cylinder of slide bar is through centre bore and stretch out centre bore.
Described hole die cavity body bottom is extended and is formed with the installing hole penetrated to the other end continuation of the body of rod, and the diameter of installing hole is less than cavity diameter, and installing hole is equipped with backstay, and the end of backstay is equipped with the adjusting cushion block.
Described backstay is stairstepping, comprises a cylinder head and a cylindrical bar, and cylinder head is arranged in cavity, and cylindrical bar is arranged in installing hole.
Advantage of the present invention and good effect are:
The successful that the present invention brings in the manufacturing industry such as production lathe, greatly reduced the damage of equipment and personnel's injury.
Between two collapsible forms of lathe; place the safeguard protection bar; when occurring that maloperation or Machine-Tool Control, brake component are malfunctioning; distance between two collapsible forms constantly reduces; oppress gradually the slide bar in the security activity bar, slide bar moves the collected machine tool electric force control device that passes to of signal of generation, instant cutting-off machine power; make lathe produce the anxious action that stops, avoid lathe to damage.By the motion bar body, stop the inertia of two collapsible forms to move, guarantee the safety operation space between two collapsible forms; Wherein, realize resetting of slide bar by the spring in the security activity bar.
For instance, the injection molding machine of plastic in forming machine or punching press be with on forcing press, in installation, debugging or the repair process of molding equipment, due to electrical equipment control fault and people for the molding equipment damage occurs in maloperation, personnel's injury accident is of common occurrence.If be furnished with the safeguard protection according to equipment of the present invention, when the installation of molding equipment, debugging or repair process, it is positioned between workbench and portable plate, not there will be security incident.
The minimizing of security incident has direct impact and significant the lifting to the economic benefit of enterprise.
The accompanying drawing explanation
