Description
Technical field
The utility model relates to a kind of oxy arc cutting tool, and in particular, it relates to a kind of circular hole cutting simple frock.
Background technology
Machined need to be cut circular hole often on steel plate, in order to reduce costs, what a lot of processing enterprises adopted is all that hand-held oxy arc cutting tool carries out circular hole cutting, the most structure of existing hand-held oxy arc cutting tool is too simple, there is no basic center of circle fixed point structure, can only on sheet material, draw in advance the circular hole profile that will cut, then along this profile mobile cutting gun carefully, cut out circle roughly, the wayward stability of hand-held oxy arc cutting tool, cutting error is large, will shake slightly because of carelessness, cause circular hole cutting not round, position wanders off.Publication number is that the utility model of CN2083528U discloses a kind of Multi-direction hole cutting clamp on August 28th, 1991, relate to oxy-acetylene flame cutting, be specially adapted to the operation of hand-held backstroke cutting circular hole, by magnet base, adjusting nut, adjusting screw(rod), cutting torch card cylinder, jackscrew, the disconnected button of suction etc., formed, cutting torch card jacket casing is on cutting torch mixing tube, by magnet base, be adsorbed on workpiece, rotate cutting torch, can complete the circular hole of required cutting.But the magnet base of this utility model need to take certain space, at sheet material area relatively hour or during sheet material out-of-shape, because magnet base takes up room too greatly, thereby cannot place magnet base, can not operate.
Utility model content
The wayward stability of existing hand-held oxy arc cutting tool, cutting error is large, and for overcoming this defect, the utility model provides a kind of working stability good, and cutting path is more regular, the circular hole cutting simple frock that cutting error is little.
The technical solution of the utility model is: a kind of circular hole cutting simple frock, comprise cutting torch card cylinder, regulating rotary lever and positioning support fastener, regulating rotary lever runs through positioning support fastener and regulating rotary lever one end and cutting torch card cylinder and is connected, between positioning support fastener and regulating rotary lever, be provided with positioning fixed mechanism, positioning support fastener bottom is rotary body.During use, on steel plate, first process an aperture, with positioning support fastener, insert in this aperture, positioning support fastener just can reside on fixed position, take positioning support fastener as pivot rotates whole frock, the oxy arc cutting gun being fixed on cutting torch card cylinder just can be along circumference cutting steel plate.By positioning fixed mechanism, the spacing of cutting torch card cylinder and positioning support fastener can be regulated, thereby the circular hole of different-diameter can be cut out.While working due to this frock, have fixing pivot, it is comparatively easy that precision control and stability are controlled, and therefore can cut out more regular circular hole.
As preferably, described positioning fixed mechanism comprises adjustment bolt, adjust bolt thread and be connected in positioning supports crown portion, and top is pressed in the regulating rotary lever that penetrates positioning support fastener.While adjusting bolt compression regulating rotary lever, regulating rotary lever and positioning support fastener are fixed with one, and the spacing of cutting torch card cylinder and positioning support fastener is also thereupon fixing; When adjustment bolt unscrews, between regulating rotary lever and positioning support fastener, can change relative position, regulate the diameter of cutting circular hole.This kind of positioning fixed mechanism is simple in structure, easy to operate.
As preferably, positioning support fastener bottom is tapered.Before cutting, need first machining small on steel plate, with conventional method ratio, be easier to process bellmouth, the tapered positioning support fastener in bottom can mate preferably with bellmouth, the positioning support fastener bottom conical surface is subject to the support of bellmouth hole wall, held stationary, is beneficial to and cuts out regular circular hole at an easy rate.
As an alternative, positioning support fastener bottom is cylindrical.By conventional method, also than being easier to process columniform aperture, the cylindrical positioning support fastener in bottom just in time mates with this aperture, also can keep preferably frock operating attitude, cuts out regular circular hole.
As preferably, above position, positioning support fastener bottom is cylindrical, and the positioning support fastener integral body structure that is formed in one.Positioning support fastener integral body is a rotary body, processes comparatively speaking more convenient.
As preferably, regulating rotary lever and the welding of cutting torch card cylinder.With welding manner, regulating rotary lever and cutting torch card cylinder are fixedly connected on to the most easily realization in technique.
The beneficial effects of the utility model are:
Can complete fast, easily and accurately circular hole cutting work.In the utility model, positioning support fastener adjustable point is at center of circular hole, has good stability and can be handling, during operation, only need, round positioning support fastener rotation regulating rotary lever, just can cut out regular circular hole.
Space hold is little, and circular hole processing specification limit is larger.In the utility model, positioning support fastener only needs the less strong point to support just can to work, and on less steel or on the not too regular steel of shape, also can carry out circular hole cutting operation.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is another kind of structural representation of the present utility model.
In figure, 1-cutting torch card cylinder, 2-regulating rotary lever, 3-positioning support fastener, 4-adjusts bolt.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment, the utility model is described in further detail.
embodiment 1:
as shown in Figure 1, a kind of circular hole cutting simple frock, comprise cutting torch card cylinder 1, regulating rotary lever 2 and positioning support fastener 3, regulating rotary lever 2 runs through positioning support fastener 3 and regulating rotary lever 2 one end and 1 welding of cutting torch card cylinder, and oxy arc cutting gun is threaded in cutting torch card cylinder 1 top.Between positioning support fastener 3 and regulating rotary lever 2, be provided with positioning fixed mechanism, positioning support fastener 3 bottoms are rotary body.Described positioning fixed mechanism comprises adjusts bolt 4, adjust bolt 4 and be threadedly connected to positioning support fastener 3 tops, and top is pressed in the regulating rotary lever 2 that penetrates positioning support fastener 3.Positioning support fastener 3 bottoms are tapered, and positions more than positioning support fastener 3 bottoms is cylindrical, and the positioning support fastener 3 integral body structure that is formed in one.
With before this frock cutting circular hole, on the steel of needs processing, find out the central point of circular hole to be cut, with drill bit, process a more shallow tapered openings and make anchor point, then the bottom with positioning support fastener 3 coordinates with this tapered openings, and with hand, slightly firmly the bottom conical surface and this tapered openings hole wall of this tool locating of vertical depression supporting member 3 keep being affixed.Handheld formula cutting gun cutting torch is fixed on cutting torch card cylinder 1 top, according to the good position from positioning support fastener 3 to cutting torch card cylinder 1 of the aperture adjustment that will process circular hole, adjust after processing circle hole radius, locking adjusting nut 4, open cutter and adjust flame, continue to press down on the other hand positioning support fastener 3, rotate on the other hand regulating rotary lever 2 and start cutting.
embodiment 2:
