Abstract

The utility model discloses an alloy bit which comprises a drill handle and a blade head, wherein the drill handle and the blade head are molded in an integrated mode, a graduated scale is arranged on the drill handle, and the diameter of the drill handle is smaller than that of the blade head. According to the alloy bit, the defects that when a drill bit is used for machining deep holes, the depth of each hole is inaccurate, the machining depth of the drill bit is controlled by workers depending on experience, labor force of workers is increased, and when a drill lip drills deep in the hole, the drill lip is easy to block by cutting bits and then is broken off are overcome. The alloy bit is an improved drill bit, so that the accuracy of the machined hole depth is improved, machining time is saved, and meanwhile the alloy bit can not be clamped in the hole in the processing process, and production efficiency is improved.

Description

A kind of alloy bit

Technical field

The utility model relates to machining tool, particularly a kind of alloy bit.

Background technology

When carrying out hole processing operation, the general roughing operation of using spiral bit to hole earlier; For the processing of hole depth, be the experience that relies on the master worker, carry out test drilling earlier, carry out the measurement of hole depth then with slide measure, if undersize continues test drilling again; Such shortcoming is the experiential operating that relies on the workman fully, has strengthened working strength of workers, and repeatedly test drilling, repeatedly uses slide measure, wastes process time; Simultaneously in order to utilize the sword head processing sections of drill bit fully, must all go deep into the sword head processing sections of drill bit in the hole, drillstock also has partly and gos deep in the hole like this, the cutting of sword head can produce cutting swarf, because the drillstock diameter is big with the first sample of sword, if chip removal is untimely, the cutting swarf that will cause drillstock to be failed in the tap is stuck, and then fracture, cause drill bit to scrap, the waste manufacturing cost.

The utility model content

Technical problem to be solved in the utility model provides a kind of alloy bit, makes things convenient for the time of deep hole processing, minimizing longhole survey.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of alloy bit, comprise integrated drillstock and sword head, and described drillstock is provided with row's graduation mark and a corresponding scale value, and the diameter of described drillstock is less than sword head 5-12mm.

Further, the start index value in the described scale value is the length value of sword head, can make things convenient for the master worker to judge the processing length of drill bit like this, and the time of drill bit is chosen in quickening, also alleviates the master worker and relies on experience to choose drill bit, and then alleviated labour intensity.

Further, the diameter of described drillstock adds man-hour less than sword head 8mm, can conveniently utilize whole sword heads of drill bit to cut, and can carry out a spot of appearance bits simultaneously.

Before the processing, only need the needs according to the machining hole degree of depth, collet is clamped a certain rule of drillstock.

Add man-hour, the feeding drill bit when collet touches work piece, can be finished processing.

Advantage: 1, drill bit deep hole processing, more accurate to the size of the degree of depth of hole processing, alleviated operator's intensity simultaneously.2, the number of times that can reduce chip removal and reduce the use of slide measure, and then reduced the operation of processing, saved process time.

3, drillstock is littler than drill bit, can prevent that drillstock from going deep in the hole, is stuck because chip removal is untimely.

Description of drawings

Fig. 1 is the schematic diagram of the utility model structure.

The specific embodiment

Embodiment one

As shown in Figure 1, the utility model is a kind of alloy bit, comprises integrated drillstock 1 and sword head 2, and described drillstock 1 is provided with row's graduation mark 3 and a corresponding scale value, and the diameter of described drillstock is less than sword head 8mm

Before the processing, need according to processing, collet is clamped corresponding 40mm scale value place on drillstock 1 graduation mark 3.

Add man-hour, the feeding drill bit when collet touches work piece, can be finished the hole of working depth 40mm.

What present embodiment showed is that the utility model is an advantage: the drill bit deep hole processing, and one-shot forming, more accurate to the size of the degree of depth of hole processing, alleviated operator's intensity simultaneously.

Embodiment two

As shown in Figure 1, present embodiment and embodiment one different place is: what present embodiment was showed is the another kind of using method of the utility model alloy bit:

Before the processing, need according to processing, collet is clamped the 70mm scale place that drillstock 2 graduation apparatus 3 indicate.

Add man-hour, the feeding drill bit when being fed into 40mm, moves back the bits operation.

After moving back bits, directly move down drill bit, can directly find out also need how much amount of feeding by the graduation mark of drillstock.

Start the lathe drill bit again, continue the feeding drill bit, when collet touches work piece, can finish the hole of working depth 80mm.

Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.

Claims
