Abstract

The invention belongs to the technical field of plasma engraving machines, and in particular relates to an auxiliary processing device. The auxiliary processing device comprises a processing head arranged on a portal frame, wherein a follow-up hold-down mechanism arranged beside the processing head; and the bottom of the follow-up hold-down mechanism is positioned below the bottom of the processing head. The technical scheme indicates that the follow-up hold-down mechanism is arranged beside the processing head, and the bottom of the follow-up hold-down mechanism is protruded below the bottom of the processing head, therefore, when plasma engraving is carried out, the follow-up hold-down mechanism is pressed against the surface or warping position of a workpiece, so that the deformation extent and warping extent of the workpiece are inhibited so as to ensure the smooth plasma engraving.

Description

Auxiliary processing device

Technical field

The invention belongs to the plasma technical field of engraving, be specifically related to a kind of auxiliary processing device.

Background technology

The plasma engraving machine is realized engraving and cutting to workpiece through isoionic high temperature; But when the plasma engraving machine is worked; Warpage and distortion take place in the workpiece of its processing easily under action of high temperature, because processing head is nearer apart from workpiece, so the part of workpiece generation warpage will hinder the motion of processing head; Thereby the Carving Machining process can not be carried out smoothly, and cause machining failure or accident easily.

Summary of the invention

The purpose of this invention is to provide a kind of auxiliary processing device, its simple structure and can guarantee carrying out smoothly of Carving Machining process.

For realizing above-mentioned purpose; The present invention has adopted following technical scheme: a kind of auxiliary processing device; Comprise the processing head that is arranged on the portal frame, it is characterized in that: the side of described processing head is provided with the servo-actuated hold-down mechanism, and the bottom of servo-actuated hold-down mechanism is positioned at the downside of the bottom of processing head; Described processing head is installed on the slide plate that can move up and down along portal frame, and the servo-actuated hold-down mechanism is arranged on the slide plate.

Can know by technique scheme; The present invention is provided with the servo-actuated hold-down mechanism at the side of processing head; And the bottom of servo-actuated hold-down mechanism is set to stretch out the downside in the bottom of processing head, and then when plasma is carved, described servo-actuated hold-down mechanism is resisted against on the plate face of workpiece or the warpage place of workpiece; Suppress the deformation extent and the warpage amplitude of workpiece, thereby guaranteed carrying out smoothly of plasma engraving.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the front view that Fig. 1 removes portal frame;

Fig. 3 is the vertical view of Fig. 2.

The specific embodiment

Shown in Fig. 1～3, a kind of auxiliary processing device comprises the processing head 20 that is arranged on the portal frame 10, and the side of described processing head 20 is provided with servo-actuated hold-down mechanism 30, and the bottom of servo-actuated hold-down mechanism 30 is positioned at the downside of the bottom of processing head 20.

The bottom of servo-actuated hold-down mechanism 30 is positioned at the downside of the bottom of processing head 20; The head that also is about to servo-actuated hold-down mechanism 30 stretches out the downside at processing head 20; The head abuts that perhaps makes servo-actuated hold-down mechanism 30 is on workpiece to be processed; Then under action of high temperature, deform or during warpage, servo-actuated hold-down mechanism 30 can come in contact prior to processing head 20 and workpiece when workpiece, and servo-actuated hold-down mechanism 30 is through itself and further being out of shape or warpage against having suppressed workpiece of workpiece; Thereby protected processing head 20, and guaranteed carrying out smoothly of Carving Machining.

The difference in height of the bottom face of the bottom face of described servo-actuated hold-down mechanism 30 and processing head 20 is 2～5mm, then both has been convenient to the Carving Machining of processing head 20, also helps the installing and locating and realization defencive function of servo-actuated hold-down mechanism 30.

Further, shown in Fig. 1～3, described processing head 20 is installed on the slide plate 40 that can move up and down along portal frame 10, and servo-actuated hold-down mechanism 30 is arranged on the slide plate 40, and described slide plate 40 can be tabular for directly, also can be flap-like.

Processing head 20 passes through slide plate 40 and realizes the upper and lower displacement of himself, to help Carving Machining; And servo-actuated hold-down mechanism 30 is arranged on the slide plate 40 equally, then can guarantee servo-actuated hold-down mechanism 30 and processing head 20 realization synchronous shift, so that better protection to be provided.

Shown in Fig. 1～3, described servo-actuated hold-down mechanism 30 is made up of at least two compressing members 31, and compressing member was located at the both sides of processing head 20 in 31 minutes or is distributed on all sides of processing head 20, to realize the protection in each orientation.

As preferred version of the present invention; Described compressing member 31 is set to two; Compressing member 31 all is arranged on the front side of processing head 20 cutting directions of advance, then when 20 pairs of workpiece of processing head are carved cutting, because compressing member 31 is located at the front side of processing head 20 cutting directions of advance; Then compressing member 31 is suppressed all the time or is resisted against on the workpiece in processing head 20 the place aheads, thereby the engraving cutting that under the situation of using less compressing member 31, has guaranteed processing head 20 is interference-free.

Further, described compressing member 31 comprises the height adjuster that matches with slide plate 40, and the downside of height adjuster is provided with hold-down head 312, and the bottom of hold-down head 312 is positioned at the downside of the bottom of processing head 20.Height adjuster can raise or reduce hold-down head 312, helps the installation and the location of hold-down head 312, and makes hold-down head 312 can adapt to various working.

Height adjuster has multiple implementation; Such as being set to cutting ferrule, depression bar 311 and slide plate 40 cooperate; As preferred version of the present invention, described height adjuster is the depression bar 311 that is arranged on the slide plate 40, and the downside of depression bar 311 is provided with hold-down head 312; The shaft of depression bar 311 is provided with external screw thread, and the upside of depression bar 311 stretches in the slide plate 40 and with slide plate 40 and constitutes threaded engagement.When needs are regulated the position of hold-down head 312, depression bar 311 is rotated up or is rotated down, then depression bar 311 drives hold-down heads 312 and rises or descend, thus the spacing between the bottom of the bottom of having realized hold-down head 312 and processing head 20 is adjusted.

Hold-down head 312 can be the square shape; As the further preferred version of the present invention; Described hold-down head 312 is spherical; The downside of depression bar 311 is provided with the housing 313 that holds hold-down head 312, and the smaller part of hold-down head 312 is partly given prominence in the outside of housing 313, cooperates for rolling between described hold-down head 312 and the housing 313.Then when hold-down head 312 is resisted against on the workpiece, is rolling friction between hold-down head 312 and the workpiece, thereby has reduced the frictional force between hold-down head 312 and the workpiece, to cut down the consumption of energy and to guarantee carrying out smoothly of Carving Machining.

The outer shape of the interior shape of described housing 313 and hold-down head 312 matches, and the diameter of housing 313 opening parts is less than the sphere diameter of hold-down head 312.

Described hold-down head 312 is a metal material, and then hold-down head 312 is not yielding, and coefficient of friction is little, remains unchanged and helps carrying out smoothly of Carving Machining with the spacing between the bottom of the bottom that guarantees hold-down head 312 and processing head 20.
