Abstract

The utility model provides gas cutting compasses which comprise a gas cutting gun. A shaft sleeve is mounted outside a cutting torch of the gas cutting gun and is fixed in a ball bearing through a nut, a sleeve ring is mounted outside the ball bearing and is connected with a protection cover in a rotating mode, a sleeve pipe is fixedly connected to the side face of the protection cover, a compasses supporting leg is mounted in the sleeve pipe and comprises a fixing rod and a centering rod perpendicularly connected with the fixing rod, the fixing rod is fixed on the sleeve pipe through a fastening piece, and a conical point is arranged at the top end of the centering rod. The gas cutting compasses are exquisite and compact in structure, can be used for arc cutting on a circular pipe or a plane steel plate, operation is simple and convenient, original tedious work of sample plate making and line drawing is avoided, and work efficiency and work quality are greatly improved.

Description

A kind of gas cutting compasses
Technical field
The utility model belongs to cutting tool technical field, especially relates to a kind of device that can carry out circular cutting on pipe and plain plate.
Background technology
In pipeline installation and connection procedure, in the time that needs will insert a pipe (calling tubule in the following text) in an other pipe (calling extra heavy pipe in the following text), must in extra heavy pipe, cut through hole according to the external diameter of tubule, conventionally adopt at present graphing method to process, its manufacturing process is that the intersection of first obtaining two tubes makees model, then cuts out the circular hole of another root pipe with model setting-out gas cutting on a pipe, and operation cannot guarantee cutting accuracy like this, second-rate, operating efficiency is low.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of gas cutting compasses, can on pipe and plain plate, carry out quickly and accurately circle cutting.
In order to reach above object, the utility model provides following technical scheme:
A kind of gas cutting compasses; comprise cutter; described cutter cutting torch is provided with axle sleeve outward, and described axle sleeve is fixed in ball bearing by nut, and ball bearing is provided with the collar outward; on the described collar, be connected with over cap; the side of described over cap is being fixedly connected with sleeve pipe, is installed with compasses supporting leg in described sleeve pipe, described compasses supporting leg comprise fixed bar and with fixed bar centering bar connected vertically; described fixed bar is fixed on sleeve pipe by securing member, and described centering masthead end has conical points.
As improvement project of the present utility model, on described fixed bar, cover has roller.
As preferred version of the present utility model, described roller radius equates with centering masthead end to the vertical range in fixed bar axle center.
Compared with prior art, the utility model has the advantage of: structure is small and exquisite, compact, can on pipe and plane steel plate, carry out circular arc cutting, easy and simple to handle, avoid original loaded down with trivial details work of doing model, setting-out, significantly improved operating efficiency and work quality.
Accompanying drawing explanation
The structural representation of the gas cutting compasses that Fig. 1 provides for the utility model;
Fig. 2 is the left view of Fig. 1.
Reference numerals list:
1-cutter, 11-cutting torch, 2-axle sleeve, 3-over cap, 4-ball bearing, 5-sleeve pipe, 6-securing member, the 7-collar, 8-nut, 9-compasses supporting leg, 91-fixed bar, the 92-bar of feeling relieved, 10-roller.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand the following specific embodiment and only be not used in restriction scope of the present utility model for the utility model is described.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
Gas cutting compasses as shown in Figure 1; comprise cutter 1; the outer axle sleeve 2 that is provided with of cutting torch 11 of described cutter 1; described axle sleeve 2 is fixed in ball bearing 4 by nut 8; ball bearing 4 is outer is provided with the collar 7, on the described collar 7, is connected with over cap 3, and over cap 3 should be arranged on the collar 7 belows; prevent the impact of cutting flame on ball bearing 4 in gas cutting process, the collar 7 and over cap 3 can effectively protect ball bearing 4 injury-free.The side of described over cap 3 is being fixedly connected with sleeve pipe 5, and in this example, sleeve pipe 5 is welded on the side of over cap 3.In described sleeve pipe 5, be installed with compasses supporting leg 9, described compasses supporting leg 9 comprise fixed bar 91 and with fixed bar 91 centering bar 92 connected vertically, fixed bar 91 is fixed on sleeve pipe 5 by securing member 6, described centering bar 92 tops have conical points.
In the time that needs cut on extra heavy pipe, first determine tubule installation site, centre bore is accomplished fluently in place suitable outside extra heavy pipe, centre bore is put into in centering bar 92 tips of compasses supporting leg 9 in gas cutting compasses, adjust the distance between cutting torch 11 and the centre bore of cutter 1 by securing member 6, this distance equates with the external diameter of tubule, if desired also the replaceable compasses supporting leg 9 with longer fixed bar 92 to adapt to the extra heavy pipe that diameter is larger.We can also adjust by nut the height of cutter cutting torch 11, and cutting torch should be less than the length of flame of cutting torch to the ultimate range on extra heavy pipe surface when guaranteeing to cut.After adjusting, open cutter, take the bar 92 of feeling relieved as the center of circle, the circular hole that cutting matches for tubule external diameter on extra heavy pipe outer surface.Because cutting torch 11 is fixed in ball bearing 4, therefore cutting torch 11 can rotate in 0 °~360 °, is convenient to staff and carries out cutting operation.
This gas cutting compasses are also used on plane steel plate and cut out circular arc, and further, in the time of cutting planes steel plate, on fixed bar 91, cover has roller 10.Roller 10 radiuses should equate with centering bar 92 tops to the vertical range in fixed bar 91 axle center, like this when with this gas cutting compasses on plane steel plate when gas cutting round piece or circular arc line segment, roller 10 conduct supports, make cutting process convenient steady.
Securing member 6 described in this example is for connecting and fixing conventional components in the mechanical fields such as screw, screw rod.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned embodiment, also comprises the technical scheme being made up of above technical characterictic.It should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
