Tapping machine

Abstract

The invention discloses a tapping machine. The tapping machine comprises a machine head assembly, a fixture, a support plate device and a guide rail device; the machine head assembly includes a motor, a base and a screw tap; the motor is fixed on the base; the tap screw is driven by the motor; the fixture includes a fixture cylinder, a first connecting rod mechanism, a first linkage rod, a pressing strip and two first linkage rod seats; the fixture cylinder and the first linkage rod seats are respectively fixed on a workbench; two ends of the first linkage rod are respectively connected with the two first linkage rod seats through bearings; the pressing strip is fixed in the middle part of the first linkage rod; the tail end of the first connecting rod mechanism is fixed to the end part of the first linkage rod; the fixture cylinder drives the first connecting rod mechanism, thereby driving the linkage rod to rotate so as to enable the pressing strip to clamp or loosen a workpiece to be machined; the support plate device includes a support plate and a support plate cylinder; the support plate is fixed on a piston rod of the support plate cylinder; the guide rail device includes two inclined surface guide rail plates and two limiting plates; the two inclined surface guide rail plates are fixed on the workbench; the two limiting plates are respectively located on the outer sides of the two inclined surface guide rail plates; and when the piston rod of the support plate cylinder stretches out, the support plate is joined with the tail ends of the inclined surface guide rail plates, and provide support for the workpiece to be machined.

Description

technical field [0001] The invention relates to a tapping machine. Background technique [0002] The current tapping machine structurally includes a frame, a workbench and a head assembly. The head assembly includes a motor, a feed shaft and a tap. The tap is directly connected to the feed shaft. When in use, when the head assembly goes down When the feed axis is pushed downwards, the tap is driven to move forward stably to tap on the workpiece to be processed; when the head assembly moves upwards, the feed axis is pulled upwards, and finally the tap is driven to withdraw from the workpiece to be processed. The structural tapping machine is only suitable for processing single-form workpieces, and the production efficiency is low. When changing the workpiece to be processed, it is also necessary to change the corresponding fixture to meet the production needs, which increases the cost of production and processing accordingly. [0003] When using the tapping machine for proc...
