Abstract
The utility model discloses a shut height adjustment device of a press, which relates to an improvement of a shut height adjustment device of a press and comprises a connecting rod, a ball screw rod and a gland, wherein the thread section of the ball screw rod is arranged in a rod hole of the connecting rod through the gland; the shut height adjustment device of the press further comprises a worm wheel and a worm; the worm wheel is arranged in the rod hole of the connecting rod and has a gap with the rod hole; the worm wheel is provided with a central threaded hole; the thread section of the ball screw rod is connected with the central threaded hole of the worm wheel; and the worm is meshed with the worm wheel, and one rod head of the worm extends out of the connecting rod. The shut height adjustment device of the press has compactness in structure as the shut height adjustment is realized at the inner part of the connecting rod; and the axial position of the ball screw rod does not change under impact load due to the self locking characteristic of the worm and wheel mechanism and the thread locking characteristic between the thread section of the ball screw rod and an inner thread of the worm wheel, thereby greatly improving the precision of shut height.
Description
Technical field
The utility model relates to the improvement to pressure machine closed height adjusting device.
Background technology
Existing closed height adjusting device mechanism is many to have increased the difficulty of processing of slide block in slide block inside, and under long-term impact loading, the tight phenomenon of lock often appears in screw thread.
Summary of the invention
The utility model provides a kind of locking effect good, the pressure machine closed height adjusting device of compact conformation at above problem.
The technical solution of the utility model is: comprise connecting rod, ball screw and gland, the thread segment of ball screw is located in the bar hole of connecting rod by gland, and it also comprises worm gear and worm screw; Described worm gear is located in the bar hole of connecting rod, and and the bar hole between have the gap, described worm gear is provided with screwed hole of centre, the thread segment of described ball screw links to each other with the screwed hole of centre of described worm gear; Described worm screw is meshed with described worm gear, and the bar head of described worm screw stretches out outside the connecting rod.
Be provided with the flat key of avoiding ball screw to rotate between described ball screw and the connecting rod.
It also comprises the worm drive device, and described worm drive device comprises drive motors, sprocket wheel and driving-chain, and described drive motors is located at the top of connecting rod, and described sprocket wheel is located at worm screw and stretches out the outer club head of connecting rod, and described driving-chain links to each other sprocket wheel with drive motors.
The utility model has changed the state of the art of in the past regulating closed height by the ball screw rotation, drives the ball screw straight reciprocating motion by worm and gear.Like this, the one, closed height is adjusted in the inner realization of connecting rod, make the compact conformation of complete machine, the 2nd, in view of the screw-threaded coupling characteristic between latching characteristics, ball screw thread segment and the worm gear internal thread of worm-and-wheel gear itself, make under shock loading, the axial location of ball screw can not change, and then has improved the precision of closed height greatly.For preventing that rotating from appearring in ball screw, between connecting rod and ball screw, be provided with flat key, can limit ball screw and occur rotating.The utlity model has the twin-lock characteristic, can improve the precision of lathe bottom dead centre greatly.
