Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0014] Such as figure 1 and figure 2 As shown, the present embodiment includes a low-speed motor 11, a casing 13, a cam bar 5, a cam nut 4, a sleeve 8, a mandrel 2, a tap rod 1, a tap 18, a stopper 3, an attack point and an attack retreat Point proximity switches 10 and 15. The low-speed motor 11 is fixed on the rear end of the box body 13; the cam nut 4 is fixed on the front end of the box body 13, and the further preferred structure is: the cam nut 4 is T-shaped, which is sleeved in the flange 9, and the edge is fixed on the flange On the plate 9, the flange plate 9 is fixed on the front end of the casing 13. The sleeve 8 is fixed on the output shaft of the low-speed motor 11, and the cam lever 5 is slidably and rotatably fixed on the inner circle of the sleeve 8. A further preferred structure is: the cam lever 5 is fixed with a guide key...

Abstract
The invention discloses a single-shaft tapping power head. A motor is fixed to the rear end of a box, and a profiling nut is fixed to the front end of the box. A sleeve is fixed to an output shaft of the motor. A profiling rod is rotationally fixed to a sleeve inner circle in a sliding manner along with the sleeve. The sleeve is rotationally fixed in the box. The front end portion of the profiling rod is connected to the profiling nut through a thread, a core rod is fixed to the front end of the profiling rod, a screw tap extension rod is fixed to the front end of the core rod, and a screw tap is fixed to the front end of the screw tap extension rod. A tapping forwarding point proximity switch and a tapping reversing point proximity switch are fixed to a support at the front end of the box. A stop block of the proximity switches is fixed to the core rod. The single-shaft tapping power head is driven by the motor of the single-shaft tapping power head, the tapping feeding movement is achieved through the profiling nut and the profiling rod, and the tapping stroke can be adjusted at random. The structure is simple and compact, cost is greatly reduced, and installing, using and adjusting are more convenient and rapid.
Description
technical field [0001] The invention relates to a tapping power head. Background technique [0002] The original 1TG tapping head was designed according to the Ministry of Machinery standard JB2504-78 "General components of combined machine tools - nominal size, parameters, interchangeable size of single-axis tapping power head". The feed tapping function can be realized only when the mechanical slide table, tapping stroke controller, brake, etc. are used together to complete the tapping of cast iron, steel and non-ferrous metals. The overall structure is complex, the installation and adjustment of each component is difficult, the position accuracy of each component is high, the failure rate is high, and maintenance is inconvenient. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, and to provide a single-axis tapping power head that can realize feed tapping by itself without using a slide ta...
