Abstract
The utility model discloses a hand screw tap which comprises an operating section as well as a tap handle and a square head, wherein the operating section consists of a cutting tap and a calibrating part; the tap handle is positioned between the operating section and the square head; a plurality of chip containing grooves are axially formed in the surface of the operating section; and scales are also arranged in the chip containing grooves and on the surface of the tap handle. The hand screw tap provided by the utility model has the beneficial effects that because the screw tap is provided with the scales and a positioning block, when internal threads of blind holes are manufactured, the depth of tapping can be easily controlled by operators, and similarly the lengths of the threads are easy to control, therefore, the production efficiency is improved, the manufacturing precision is improved, and the economic benefit is improved.
Description
Technical field
The utility model relates to a kind of screw tap, especially a kind of set tap.
Background technology
In the internal thread machining process, often run into the situation of the hand tapping of having to, but double thread length has when necessarily requiring, particularly blind hole processing, the operator is difficult to the controlled working degree of depth, careless slightlyly deviation will occur: if reach is inadequate, tapping is wasted time and energy again; If because of carelessness screw tap is rotated to the end, be easy to cause screw tap fracture or thread damage.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of set tap of being convenient to control reach when the processing blind hole internal thread, and this screw tap also is applicable to process the through hole internal thread.
The technical solution of the utility model is:
A kind of set tap, comprise the active section that is formed by cutting cone and calibrated section, and taper shank and square toes, described taper shank is between active section and square toes, described active section surface has many chip pockets vertically, it is characterized in that: in the described chip pocket and taper shank surface also is provided with scale.
Preferably, described taper shank is provided with external screw thread, and the screw thread of described external screw thread and calibrated section is end to end, and described externally threaded size is identical with the thread size of calibrated section.
Further, described set tap surface also is provided with locating piece, and locating piece is loop configuration, and described locating piece is connected with screw tap by the screw thread of the external screw thread on the taper shank or calibrated section.
The beneficial effects of the utility model are: owing to be provided with scale and locating piece on the screw tap, when the processing blind hole internal thread, the operator just can control the degree of depth of tapping at an easy rate, in like manner controls the length of screw thread.When improving machining accuracy, also improved production efficiency, increased economic efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Now in conjunction with the accompanying drawings and embodiments the utility model is further described:
As shown in Figure 1, a kind of set tap, comprise the active section 3 that is formed by cutting cone 1 and calibrated section 2, and taper shank 4 and square toes 5, taper shank 4 is between active section 3 and square toes 5, active section 3 surfaces have many chip pockets 6 vertically, and in the chip pocket 6 and taper shank 4 surfaces also are provided with scale 7, are used for the length of the internal thread of indicating to process.
Taper shank 4 is provided with external screw thread 8, and external screw thread 8 is end to end with the screw thread of calibrated section 2, and the size of external screw thread 8 is identical with the thread size of calibrated section 2.
The screw tap surface also is provided with locating piece 9, and locating piece 9 is loop configuration, and locating piece 9 is connected with screw tap by the screw thread of the external screw thread 8 on the taper shank 4 or calibrated section 2.
The zero graduation line of scale 7 is arranged on the boundary of cutting cone 1 and calibrated section 2, guarantees that scale 7 represented reaches are effective lengths.
During the processing blind hole internal thread, according to required useful thread, locating piece 9 forwarded to corresponding graduation mark near a sidespin of cutting cone 1 align, then cooperate windeisen to carry out tapping, when locating piece 9 touches surface of the work, can stop tapping, withdraw from screw tap to opposite direction.
During processing through hole internal thread, locating piece 9 is screwed out, separate with screw tap, cooperate windeisen to carry out tapping with screw tap again.
