Detailed Description
The present invention will be described in detail with reference to the accompanying drawings 1, 2 and 3. Wherein, in fig. 3, the part a is the installation position of the present invention.
The utility model discloses a lathe tailstock movement limiting device, which comprises a mounting seat 5 fixed at the outer end of a lathe tailstock outer sleeve 1 and a limiting seat 8 fixed at the outer end of a lathe tailstock inner sleeve 2, wherein an insulating sleeve 6 is axially fixed at the outer end of the mounting seat 5 along the lathe tailstock, and a limiting rod 7 which can be adjusted in a left-right movement mode is arranged in the insulating sleeve 6; the outer end of the limiting seat 8 is axially connected with a mounting sleeve 9 along the lathe tailstock, a spring 10 and a pressing block 11 are arranged in the mounting sleeve 9, and the spring 10 acts on the inner end of the pressing block 11 to enable the outer end of the pressing block 11 to be tightly abutted against the inner end of the limiting rod 7; 7 right-hand members of gag lever post are equipped with binding post I14, 1 outer end of outer sleeve is equipped with binding post II 12, and binding post I14 is connected with II 12 electricity of binding post.
In one embodiment, the limiting rod 7 is in threaded connection with the insulating sleeve 6, and the limiting rod 7 is sleeved with a locknut 13, and the locknut 13 is tightly fastened to the outer end of the insulating sleeve 6. The inner threaded connection of spacing seat 8 is in the outer end of inner skleeve 2, the outer end of spacing seat 8 of installation cover 9 threaded connection, briquetting 11 is "T" type, and its main aspects card dress is in the outer end of installation cover 9, and the tip stretches out and offsets with the inner of gag lever post 7 behind the outer end of installation cover 9.
Preferably, the limiting rod 7, the pressing block 11, the limiting seat 8 and the mounting sleeve 9 are all made of copper materials with good electric conductivity.
The working principle is as follows: when the lathe tailstock locking device is used, according to the designed maximum moving distance of the outer sleeve 1 of the lathe tailstock, the limiting rod 7 is rotated by means of a measuring tool, the pressing block 11 compresses the spring 10 and moves to a set value, the set value is smaller than the designed maximum moving distance of the outer sleeve 1, and the anti-loose nut II 13 sleeved on the limiting rod 7 is locked; connecting the wiring terminal I14 and the wiring terminal II 12 with the control end of the tailstock mobile motor through leads, and tightly abutting the limiting rod 7 with the pressing block 11 to form a closed loop, wherein the tailstock mobile motor works normally; when the tailstock moves beyond the relative limit position with the workpiece, the outer sleeve 1 moves backwards relative to the inner sleeve 2, the limiting rod 7 is separated from the pressing block 11, the closed loop is disconnected, the disconnected signal is fed back to the control end of the tailstock moving motor, and the tailstock moving motor stops working, so that the problem that the broken teeth of the gear and the rack which drive the tailstock to move are damaged when a worker observes and judges inaccurately or does not concentrate attention is solved. And the control terminal voltage of the tailstock mobile motor is 24V and is a safe voltage, so that the tailstock mobile motor is safe when a closed loop is conducted.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and not intended to limit the scope of the present invention, so that all equivalent changes made by the contents of the claims of the present invention should be included in the scope of the claims of the present invention.
