The plasma cutting torch bit shift anti-collision device mainly adopts a rotary plate which is connected with a bottom ring through a fastener, a permanent magnet and an electric inductance approximate sensor are installed on a lower press ring, a cushion iron is arranged between the bottom ring and the lower press ring, an electric appliance insulating component bakelite is sleeved in a conical hole of the lower press ring, an upper press ring is sleeved on the upper end of an electric appliance insulating component bakelite sleeve and is connected with the lower press ring, and a plasma cutting torch is installed in the upper press ring and the electric appliance insulating component bakelite sleeve. The plasma cutting torch bit shift anti-collision device has simple, compact, and rational structure, low manufacture cost, and reliable and stable performance, signals can be sent through the electric inductance approximate sensor to notice a control system, the control system can execute a corresponding order to protect the field, cutting torch protection is finished through detecting the separation and the dislocation of the bottom ring and the lower press ring, and the device safety can be protected.
Description
Technical field
The utility model relates to a kind of plasma cutting gun displacement colliding-proof device, specifically is used for the cutting torch protection (in 360 ° of scopes) of numerical control plasma cutting machine motion, belongs to the welding and cutting device technical field.
Background technology
In prior art, plasma cutting-torch only relies on the clamping of two points to realize the crashproof effect of vertical and horizontal in the plane.If undue the clamping, then plasma cutting-torch can sever clamper because of collision; If two points clamp inappropriate or do not clamp fully, then plasma cutting-torch can not continue operation and causes breaking because of machine has stop signal.Like this, Ang Gui plasma cutting-torch and clamper will bring about great losses to the user.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point; thereby provide a kind of plasma cutting gun displacement colliding-proof device; can send signal by the inductive type proximity transducer, detect the disengaging or the dislocation of foundation ring and lower clamping ring and finish the cutting torch protection, and can protect device security.
Main solution of the present utility model is achieved in that
The utility model mainly adopts flap to be connected with the foundation ring by securing member, and permanent magnet and inductive type proximity transducer are housed on the lower clamping ring; Between foundation ring and lower clamping ring parallels is set, electrical apparatus insulation spare bakelite cover is packed in the lower clamping ring taper hole, and last trim ring is inserted in the upper end of electrical apparatus insulation spare bakelite cover, and is connected with lower clamping ring, and plasma cutting-torch is packed into and gone up during trim ring and electrical apparatus insulation spare bakelite overlap.
Have locating hole on the described lower clamping ring.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Low cost of manufacture, dependable performance is stable; Can send signal by the inductive type proximity transducer, can inform control system, control system can be carried out corresponding instruction and keep the scene intact; Detect the disengaging or the dislocation of foundation ring and lower clamping ring and finish the cutting torch protection, and can protect device security.
Description of drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure vertical view.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The optimal way that the utility model is implemented is referring to Fig. 1, shown in Figure 2: its mainly by flap 1, pin 2, foundation ring 3, lower clamping ring 4, electrical apparatus insulation spare bakelite cover 5, permanent magnet 6, parallels 7, go up trim ring 8, plasma cutting-torch 9, securing member 10, inductive type proximity transducer 11 and screw 12 etc. and form.
The utility model adopts flap 1 to be connected interface as this device and the external world with foundation ring 3 by securing member 10 (screw, nut), the accurate location of pin 2 conducts and lower clamping ring 4 is housed on the foundation ring 3 and flexibly connects; Permanent magnet 6 is contained on the lower clamping ring 4, has locating hole on lower clamping ring 4, and the inductive type proximity transducer 11 that is threaded is housed, and between foundation ring 3 and lower clamping ring 4 parallels 7 is set, and parallels 7 guarantees that foundation ring 3 is connected with the reliable of lower clamping ring 4; Electrical apparatus insulation spare bakelite cover 5 self centering in lower clamping ring 4 taper holes of packing into, last trim ring 8 is inserted in the upper end of electrical apparatus insulation spare bakelite cover 5, be connected with lower clamping ring 4 by screw 12, plasma cutting-torch 9 is put into trim ring 8 and electrical apparatus insulation spare bakelite cover 5, thereby has formed torch cutting anti-collision device.
The operation principle of the present utility model and the course of work:
The utility model mainly is to detect foundation ring 3 by electromagnetic induction (inductive type proximity transducer 11 sends signal) to finish the cutting torch protection with the disengaging or the dislocation of lower clamping ring 4.
Because being housed on the lower clamping ring 4, permanent magnet 6 and inductive type proximity transducer 11 and foundation ring 3 formed the system of flexibly connecting; make cutting torch bear certain thrust at 360 degree any directions; inductive type proximity transducer 11 is the distances that detect between foundation ring 3 and the lower clamping ring 4; in case cutting torch is clobber at the volley; the stressed suction of cutting torch greater than 6 pairs of lower clamping rings 4 of permanent magnet; lower clamping ring 4 will be crooked or be broken away from; when the distance between foundation ring 3 and the lower clamping ring 4 changes (greater than 1.5mm); inductive type proximity transducer 11 just sends a signal of telecommunication; can inform control system, control system can be carried out corresponding instruction and keep the scene intact.
