Abstract
The utility model relates to a lengthened screw tap with a sleeve. The lengthened screw tap comprises a conical head, a lengthening rod and a sleeve end, and is characterized in that the conical head is provided with cutter teeth and is connected with a smaller end of the sleeve end through the lengthening rod, wherein the conical head, the lengthening rod and the sleeve end are connected through electric welding. When the lengthened screw tap with the sleeve is used, the required lengthened screw tap with the sleeve is selected according to the specification of thread to be machined, a sleeve tool is placed into a larger end of the sleeve end and is turned, and the conical head is driven to rotate through the lengthening rod so as to realize internal thread machining. Since one end of the lengthening rod is welded with the sleeve end, the lengthened screw tap with the sleeve can simultaneously adapt to machining of an electric tool and manual machining. The lengthened screw tap with the sleeve has a simple structure and is convenient to use.
Description
Technical field
The utility model relates to assembly tool field, specifically a kind of lengthening screw tap with sleeve.
Background technology
Screw tap is a kind of cutter of machining internal thread, has vertically groove.Also be tap.Screw tap is divided into straight trough screw tap according to its shape, spiral fluted tap and spiral pointed tap.Straight trough screw tap handling ease, precision is lower slightly, and output is larger.Be generally used for engine lathe, the screw thread processing use of drilling machine and tapping machine, cutting speed is slower.Spiral fluted tap is used for numerical control machining center drilling blind hole use, and process velocity is very fast, and precision is high, and chip removal is better, centering good.Spiral pointed tap front portion has to hold cuts groove, for the processing of through hole.The screw tap that present tools factory provides is mostly coated taps, and service life and the cutting ability of coated taps all improve a lot.The screw tap cutting load of isometrical design does not distribute rationally, and crudy is high, but manufacturing cost is also high.The not isometrical design of the normal employing of tap for trapezoidal thread.
Screw tap on the market can simply be divided into machine tap and set tap two classes, existing screw tap is due to the restriction to material, can working depth limited, in the time of between needs processing is compared with deep space, often there is no simple and effective settling mode, mostly by customization screw tap, solve, also there is no a kind of ready-made available sleeve barrel tool processing at present compared with the lengthening screw tap with sleeve of deep hole position.
Summary of the invention
The utility model, for above technical problem, provides a kind of ready-made available sleeve barrel tool processing compared with the lengthening screw tap with sleeve of deep hole position.
The utility model is achieved through the following technical solutions.
A lengthening screw tap for sleeve, comprises conehead, extension bar, socket end, it is characterized in that being provided with cutter tooth on conehead, and conehead is connected compared with small end with socket end by extension bar.Between conehead, extension bar, socket end, by electric welding, connect.
During use, the screw thread specification of processing, chooses the needed lengthening screw tap with sleeve as required, at the larger end of socket end, puts into sleeve barrel tool, and turnbarrel instrument, by extension bar, drives conehead rotation, thereby realizes internal thread machining.Because the utility model is welded with socket end in extension bar one end, therefore can be applicable to electric tool simultaneously and manually process.
The utility model is simple in structure, easy to use.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model structural representation, wherein:
1-conehead, 2-extension bar, 3-socket end.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A lengthening screw tap for sleeve, comprises conehead 1, extension bar 2, socket end 3, it is characterized in that being provided with cutter tooth on conehead 1, and conehead 1 is connected compared with small end with socket end 3 by extension bar 2.Between conehead 1, extension bar 2, socket end 3, by electric welding, connect.
During use, the screw thread specification of processing, chooses the needed lengthening screw tap with sleeve as required, at the larger end of socket end 3, puts into sleeve barrel tool, and turnbarrel instrument, by extension bar 2, drives conehead 1 rotation, thereby realizes internal thread machining.Because the utility model is welded with socket end 3 in extension bar 2 one end, therefore can be applicable to electric tool simultaneously and manually process.
The utility model is simple in structure, easy to use.
Claims (2)
1. with a lengthening screw tap for sleeve, comprise conehead, extension bar, socket end, it is characterized in that being provided with cutter tooth on conehead, conehead is connected compared with small end with socket end by extension bar.
