A simple tapping mechanism for drilling machine

Abstract

The invention provides a simple tapping mechanism for a drilling machine. The simple tapping mechanism comprises a friction wheel with a sealing ring, a double-disc type friction wheel, a bearing, supports, a drill bit clamp, a workpiece clamp and a guide rail. The simple tapping mechanism is characterized in that the friction wheel with the sealing ring is connected with a drilling machine main shaft, the double-disc type friction wheel is arranged between the two supports through the bearing, one end of the double-disc type friction wheel is fixedly connected with the drill bit clamp, the workpiece clamp is arranged on the guide rail in a sliding mode, the two supports are fixedly connected to the guide rail through bolts and nuts, and a left wheel body and a right wheel body of the double-disc friction wheel are driven by left-right sliding of the double-disc type friction wheel between the two supports to make contact with the friction wheel with the sealing ring respectively so as to achieve forward and reverse rotating of the drill bit clamp; the drill bit clamp is used for clamping screw taps. By means of the simple tapping mechanism for the drilling machine, the tapping process is made to be easier and more convenient to operate, the reversing process is the tapping process and conducted along with the tapping strength, no active reversing mechanism is needed, the tapping accuracy is improved due to guidance of the guide rail, and meanwhile, the simple tapping mechanism is simple in structure, convenient to maintain and low in cost.

Description

Technical field: [0001] The invention relates to a tapper, in particular to a simple tapping mechanism for a drilling machine. Background technique: [0002] The published application number on October 31, 2001 is the patent application of 002659425, which discloses a technical scheme of a tapping head for a drilling machine, which includes a connecting mechanism connected with the sleeve and the main shaft of the drilling machine and installed on the The forward and reverse tapping mechanism on the connecting mechanism. [0003] The patent application with the application number 022718400 published on May 14, 2003 discloses a technical scheme of a tapper for a drilling machine, which includes a casing, a stop mechanism of the casing and a forward and reverse tapping located in the casing mechanism. However, the above two tapping heads all adopt a gear transmission scheme, and the structure is relatively complicated and the cost is relatively high. [0004] The applicatio...
