Mobile internal thread making machine

Abstract

The present invention discloses a mobile internal thread making machine. The mobile internal thread making machine comprises a support, a motor, a transmission mechanism, a fixture and a cutting tool, wherein the motor, the transmission mechanism, the fixture and the cutting tool are arranged on the support. The transmission mechanism comprises a transmission shaft. The motor drives the cutting tool to rotate through the transmission shaft. The bottom of the support is provided with rolling wheels. The transmission shaft comprises a driving shaft and a driven shaft. The driving shaft and the driven shaft are connected through a safety mechanism. The safety mechanism comprises a main receiving disk connected with the driving shaft, an auxiliary receiving disk connected with the driven shaft and steel balls. The end face of the main receiving disk and the end face of the auxiliary receiving disk are provided with main holes and auxiliary holes correspondingly, and the main holes and the auxiliary holes correspond to one another. The steel balls are clamped into the main holes and the auxiliary holes to connect the driving shaft and the driven shaft. The auxiliary receiving disk is also provided with adjusting holes which communicate with the corresponding auxiliary holes and are provided with internal threads. Adjusting bolts penetrate through the adjusting holes. Springs are arranged between the steel balls and the adjusting bolts. The mobile internal thread making machine can effectively protect the motor and other circuit elements against damage, guarantee smooth tapping operation and improve the operating efficiency, can be moved and is convenient to transport.

Description

Technical field [0001] The invention relates to a mechanical manufacturing equipment, in particular to a mobile internal thread making machine. Background technique [0002] The production of internal threads has also become tapping. The internal thread production machine is a kind of machine that processes the inner surface of the hole of various parts with different specifications of through holes or blind holes, such as the housing, the end face of the equipment, the nut, and the flange. Mechanical processing equipment for internal threads, screws or buckles. The existing internal thread making machine generally includes a support and a motor set on the support, a transmission mechanism, a fixture for clamping the workpiece, and a tool for tapping the workpiece. The transmission mechanism includes a transmission shaft. The axis drives the tool to make a rotary motion, and the tool gradually advances to the workpiece direction and performs tapping operation during the rotation...

AI Technical Summary

Problems solved by technology

Existing internal thread making machines generally include a support and a motor mounted on the support, a transmission mechanism, a fixture for clamping the workpiece, and a tool for tapping the workpiece. The transmission mechanism includes a transmission shaft, and the motor passes through the transmission The shaft drives the tool to rotate, and the tool gradually advances toward the workpiece during the rotation and performs tapping operations; however, sometimes the tool stops rotating due to excessive resistance during tapping operations, and the drive shaft stops at this time. The motor is blocked, and a large current is generated to cause damage to the motor and other circuit components, which affects the smooth progress of the tapping operation and reduces the working efficiency; in addition, the support is generally immovable. Although the stability is better, it is not easy to move and cannot adapt to multiple use cases
