Abstract
The utility model relates to a tapping device of a numerical-control drill. The tapping device comprises a main shaft and a tapping cone which is arranged on the lower portion of the main shaft, the end portion of the main shaft is provided with a rotary encoder which is connected with the main shaft, and the rotary encoder is connected with a controller through a system line. According to the tapping device, the rotary encoder is arranged on the end portion of the main shaft, a tapping point of the tapping cone can be detected and transferred to a control point by the rotary encoder during tapping; and when the tapping cone is broken, a tapping cone breaking point can be found quickly and accurately according to data stored in the controller to continue the tapping operation, so that the probability of workpiece scrapping caused by the broken tapping cone is eliminated, and the rate of finished products is greatly improved.
Description
Technical field
The utility model relates to a kind of numerical control and bores chasing bar.
Background technology
The function that can both realize tapping is bored in traditional numerical control, but its tapping can only one-shot forming, attacks and changes screw tap after half again and just can rot silk when the tapping substantially for fracture of wire awl or a certain silk hole take place.This is that namely initial 0 can't be found because entering of screw tap changed; Traditional numerical control brill is not looked for 0 function, screw tap is accurately entered a little be difficult to basically realize.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of and can realizes looking for the numerical control of 0 function to bore chasing bar.
The technical solution adopted in the utility model is for this reason: the utility model comprises main shaft, is arranged on the tapping awl of main shaft bottom, and spindle nose is provided with the rotary encoder that is connected with main shaft, and rotary encoder is connected to controller by system line.
The utility model has the advantages that: the utility model arranges rotary encoder at spindle nose, and rotary encoder can detect and be transferred to the control point to the tapping point of screw tap in tapping process; When the generation fracture of wire is bored phenomenon, can find fracture of wire awl point to proceed the tapping operation by the data of controller storage fast, accurately, to have avoided boring the possibility that causes workpiece to scrap because of fracture of wire, yield rate greatly improves.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 is that main shaft, 2 is that rotary encoder, 3 is system line among the figure.
The specific embodiment
The utility model comprises main shaft 1, is arranged on the tapping awl of main shaft 1 bottom, and main shaft 1 end is provided with the rotary encoder 2 that is connected with main shaft 1, and rotary encoder 2 is connected to controller by system line 3.
Claims (1)
1. chasing bar is bored in numerical control, it is characterized in that, comprises main shaft, is arranged on the tapping awl of main shaft bottom, and spindle nose is provided with the rotary encoder that is connected with main shaft, and rotary encoder is connected to controller by system line.
