Abstract

The utility model relates to an apparatus for protecting the cutting torch of a plasma cutting machine, comprising an insulating jacket, a clamp ring, a movable seat, a fixed seat, a steel wire, a spring and a press cap. The insulating jacket is sheathed on the cutting torch, the clamp ring is sheathed on the step of the insulating jacket, the inner wall of the movable seat is attached to the conical face of the insulating jacket, the upper wall of the inner side of the fixed seat is attached to the movable seat, the fixed seat is connected with the press cap through the steel wire, and the spring is arranged between the movable seat and the press cap. When the cutting torch is crashed with workpieces to be cut or obstacles, the apparatus for protecting cutting torch of plasma cutting machine can have vibration damping and buffering actions and protect the cutting torch of the cutting machine from being damaged.

Description

CUT cutting torch protective device

The utility model relates to the CUT that is used for metal processing, relates to CUT cutting torch protective device particularly.

In the cutting process of disembarking such as numerical control; the cutting torch of CUT usually can cause the cutting torch damage that is collided sometimes owing to the barrier on operating personnel's misoperation or cutting workbench surface; when particularly carrying out the plasma cutting under water, cutting torch is because of the easier generation of the impaired accident of collision.

For this reason, the utility model proposes a kind of grade cutting machine cutting torch protective device of disembarking, to address this problem.

The utility model adopts following technical measures: protective device comprises insulating jacket, hold-down ring, sliding seat, holder, steel wire, spring, gland, insulating jacket is placed on the cutting torch, the insulating jacket outer wall is that a conical surface and upper end offer step, and hold-down ring is placed on the step of insulating jacket; The sliding seat inwall also is the conical surface that can fit with the insulation centre cover conical surface, and the sliding seat outer rim is also to be the conical surface at the bottom of flange, the outside, and the part that inboard upper wall of holder and sliding seat fit also is a conical surface; Holder is connected with gland by steel wire, and spring places between sliding seat and the gland.

The utility model has been installed protective device on the cutting torch of existing cutting machine; after cutting torch and the workpiece that will cut or other barrier bump; cutting torch is protecting the cutting torch of cutting machine injury-free because the elastic reaction of protective device just can play vibration damping and buffering effectively.

Below in conjunction with drawings and Examples, the utility model is done one describes in detail:

Fig. 1 is the utility model structure cross-sectional schematic.

Fig. 2 is that the A-A of Fig. 1 is to schematic top plan view.

See also Fig. 1, shown in Figure 2, protective device comprises insulating jacket 9, hold-down ring 4, sliding seat 6, holder 7, steel wire 3, gland 1, spring 11, insulating jacket 9 is placed on the cutting torch 12, insulating jacket 1 outer wall is that a conical surface and upper end offer step, and hold-down ring 4 is placed on the step of insulating jacket 9; Sliding seat 6 inwalls also are the conical surface that can fit with insulating jacket 9 conical surfaces, sliding seat 6 outer rims are also to be the conical surface at the bottom of flange, the outside, sliding seat 6 outer rims leave the preformed hole that sensor 5 can be set, preformed hole can be provided with 2-4 according to actual needs, holder 7 with the lowering or hoisting gear 13 interlock fixed stations of cutting machine bolt (lowering or hoisting gear 13 with dashed lines in Fig. 1 is represented) mutually, the part that holder 7 inboard upper walls and sliding seat 6 fit also is a conical surface, is embedded with a steel ball 8 between the conical surface of the conical surface at the bottom of sliding seat 6 outsides and holder 7 inboard upper walls.Holder 7 is connected with gland 1 by steel wire 3, and spring 11 places between sliding seat 6 and the gland 1, and cutting torch 12 also passes spring 11 certainly, offers the annular groove that can shelve spring 11 lower ends on the sliding seat 6, also offers the circular groove that can shelve spring 11 upper ends on the gland 1.

Please continue to consult Fig. 1, Fig. 2, assembly relation of the present utility model can be described as follows: cutting torch 12 is packed in the insulating jacket 9, be screwed in the screw of sliding seat 6 through hold-down ring 4 with screw 10 then, after screw 10 is fastening, can make cutting torch 12, insulating jacket 9, hold-down ring 4, sliding seat 6 becomes a rigid unitary, steel wire 3 links together gland 1 and holder 7 through attachment cap 2, spring 11 1 end bearings are on gland 1, the other end is bearing on the sliding seat 6, because the elastic reaction of spring 11, guaranteed that sliding seat 6 and holder 7 can fit tightly, and the installation of steel ball 8 reaches positioning action.
