Abstract
The utility model relates to a knife apparatus used to process a step hole structural art, wherein the knife body comprises four coaxial pillar bodies, wherein the diameter of the pillar bodies on the knife body from front to back gradually becomes bigger, a stage face with a blade 6 degree/8 gradient between adjacent pillar bodies, the pillar body outer end in the front most is equipped with a cone drill, a blade 6 degree/8 gradient between the knife body and a knife handle, a continuous spiral crumb withdrawing dent is equipped from the knife body front end to the knife handle, and the back end of the crumb withdrawing dent extends over the step face between the knife body and the knife handle. The utility model integrates drilling, boring and hinging together, when processing the step hole, the one time processing and shaping can be realized, which ensures the concentration of the step hole, the yield rate of the product can be increased from the original 40% to above 99%, meanwhile the processing efficiency is increased by near 10 times compared with the past craft.
Description
Technical field
The utility model relates to the cutter structure field in order to processing step hole.
Background technology
In existing processing step hole technology, normally offer isometrical aperture earlier with boring cutter earlier, change borer again, feed processes the hole of different-diameter respectively one by one.Above-mentioned processing technology number of changing knife is many, and each tool changing has all directly influenced the concentricity of stepped hole, when before the processing brake for motorcycle, rousing the combination inclined hole that covers especially, particularly complicated, often can't process concentric stepped hole and influence the cooperation that is installed in the gear shaft in the stepped hole, make the performance of brake be subjected to heavy damage.
The utility model content
The utility model purpose is to design a kind of gang tool, need not tool changing, can the time processing stepped hole.
The utility model comprises cutter hub and the coaxial handle of a knife that is connected the cutter hub rear end, it is characterized in that described cutter hub is made up of four sections coaxial cylinders, cutter hub front end to the column diameter of rear end strengthens one by one, be provided with the step surface that gradient is 6 °/8 swords between adjacent cylinder, establish taper bit in cylinder outer end foremost, be provided with the step surface that gradient is 6 °/8 swords between cutter hub and handle of a knife, be provided with continuous helical form bit-withdrawing slot from the cutter hub front end to handle of a knife, the rear end extend through cutter hub of described bit-withdrawing slot and the step surface between handle of a knife.
The utility model collection brill, boring, hinge are one, during processing step hole, can realize the time processing moulding, guaranteed stepped hole with one heart, the percentage of A-class goods of product can be brought up to more than 99% by former 40%, simultaneously working (machining) efficiency also more in the past technology improve nearly 10 times.
Description of drawings
Fig. 1 is the utility model structural representation.
Specific embodiment
As shown in Figure 1, cutter hub is made of four coaxial cylinders, the diameter of cylinder 1, cylinder 2, cylinder 3, cylinder 4 is processed one by one, in cylinder 1 and 2 of cylinders, cylinder 2 and 3 of cylinders, cylinder 3 and 3 of cylinders, cylinder 4 and 5 step surface 6,7,8,9 transition that are 6 °/8 swords respectively with gradient of handle of a knife, establishing angle at the front end of the cylinder 1 of diameter minimum is 110 ° conic drill 10, to the handle of a knife 5 of crossing step surface 9 two helical form bit-withdrawing slots 11,12 is set from the front end of cylinder 1.
Claims (3)
1, a kind of gang tool, comprise cutter hub and the coaxial handle of a knife that is connected the cutter hub rear end, it is characterized in that described cutter hub is made up of four sections coaxial cylinders, cutter hub front end to the column diameter of rear end strengthens one by one, be provided with the step surface that gradient is 6 °/8 swords between adjacent cylinder, establish taper bit in cylinder outer end foremost, be provided with the step surface that gradient is 6 °/8 swords between cutter hub and handle of a knife, be provided with continuous helical form bit-withdrawing slot from the cutter hub front end to handle of a knife, the rear end extend through cutter hub of described bit-withdrawing slot and the step surface between handle of a knife.
