Example Embodiment

[0013] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0014] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an internal thread tapping device that can quickly process internal threads at one time and has high efficiency.

[0015] Such as figure 1 As shown, the motor 12 drives the belt drive 1 to move. The large pulley shaft of the belt drive 1 is connected to the cam 3 shaft through the electromagnetic clutch 2. The cam 3 is rotatably hinged on the frame 13, and the tail of the sector gear 4 is movably connected to the cam 3. It forms a high pair. The middle part of the sector gear 4 can be pivoted and hinged on the frame 13. When the cam 3 rotates, the sector gear 4 can be driven to swing with the middle part of the sector gear 4 and the frame 13 as an axis. The head of the sector gear 4 The teeth of the part gear mesh with the teeth of the rack 5 with a ball nut....

Abstract

The invention provides an internal thread tapping device and a control system. A motor drives a belt drive to move, and a big belt wheel shaft of the belt drive is connected with a cam shaft through an electromagnetic clutch. The cam is hinged to a machine rack in a rotatable mode, and the tail portion of a sector-shaped gear is movably connected with the cam to constitute a higher pair. The middle of the sector-shaped gear is rotatably hinged to the machine rack, and teeth of a head gear of the sector-shaped gear are meshed with teeth of a rack with a ball nut. The rack with the ball nut and a ball screw constitute a rolling screw pair. The ball screw is fixedly connected with a small gear, and the small gear is meshed with a big gear. A screw rod is mounted at the center of a big gear through a shaft sleeve of the big gear, the big gear rotates, and the screw rod also rotates. The screw rod can slide in the shaft sleeve of the big gear, and the screw rod and a nut in the machine rack constitute a sliding spiral pair. A screw tap is mounted at the lower end of the screw rod, and the screw pitch of the screw tap and the screw pitch of the screw rod are the same. The internal thread tapping device and the control system have the advantages that tapping machining of internal threads are achieved quickly at a time, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of machining, and relates to an internal thread tapping device and a control system. Background technique [0002] Threaded connection is a widely used detachable connection, which has the advantages of simple structure, reliable connection, and convenient assembly and disassembly. Thread is the key part of thread connection and screw transmission, and the processing of internal thread is complicated and difficult. Commonly used methods for processing internal threads are: tap tapping, turning, extrusion tap, and boring. Tapping is the most widely used method in internal thread processing, especially for small-sized internal threads, tapping is almost the only processing method; traditional lathe tapping, drilling machine tapping, and special tapping machine equipment have complex structures and are difficult to process internal threads. The processing time is long and the processing efficiency is low when...
