Abstract
A mechanism capable of adjusting a transmission gap of a gear rack comprises a reduction gear box body, a reduction gear, a servo motor, a moving sliding platform, a hinge shaft, a pressing cover and a gap adjustment mechanism, wherein the reduction gear box body is arranged on the moving sliding platform. A bottom plate and a support arm rod are fixed on the reduction gear box body, the hinge shaft is arranged between the moving sliding platform and the pressing cover, the pressing cover is arranged on a hinge shaft support plate, the hinge shaft support plate is arranged on the moving sliding platform, the reduction gear is arranged on the reduction gear box body, the servo motor is arranged on the reduction gear, and a gear is arranged on the reduction gear in an assembled mode. A gap adjustment mechanism is composed of a sliding rod seat and an adjustment base, the sliding rod seat is arranged on the moving sliding platform in an assembled mode, an adjustment screw rod, a spring and a sliding rod are arranged on the sliding rod seat, a steel ball is arranged between the sliding rod and the support arm rod, and a locknut and an adjusting screw are arranged on the adjustment base. The mechanism capable of adjusting the transmission gap of the gear rack can enable the gear rack which drives the sliding platform to move to obtain a proper transmission gap, enables a numerical control machine tool to have positioning accuracy and repeated positioning accuracy meeting requirements, and reduces manufacturing cost of a machine tool.
Description
Technical field
What the present invention relates to is the moving structure of processing major axis class Digit Control Machine Tool slide unit, particularly relates to the mechanism in a kind of regulating wheel rack-driving gap
What be that the moving structure of this type of Digit Control Machine Tool slide unit uses is gear ﹠ rack structure.What be specifically related to is by combinations such as servomotor, reductor, rack-and-pinion and gap adjustment links, make and drive the suitable drive gap of rack-and-pinion acquisition that slide unit moves, thereby the positioning accuracy and the repetitive positioning accuracy that make such Digit Control Machine Tool have to meet the demands, and reduce the manufacturing cost of lathe.
Background technology
Processing major axis class Digit Control Machine Tool (displacement of slide unit is greater than 6 meters usually); the structure that its driving slide unit moves should not adopt ball screw arrangement; many is to adopt gear ﹠ rack structure; and driven by Dual-Servo Motor; be convenient to the drive gap of control gear tooth bar, but the lathe manufacturing cost is high.Adopt the transmission of single servo motor driven wheel tooth bar, and made up with clearance adjustment mechanism, can make rack-and-pinion obtain suitable drive gap, namely satisfy the requirement of slide unit positioning accuracy and repetitive positioning accuracy, reduced again the manufacturing cost of lathe.
Summary of the invention
The purpose of this invention is to provide a kind of mechanism that adjusts accurately, easily the rack-and-pinion drive gap.
The technical scheme that adopts is:
a kind of mechanism that adjusts the rack-and-pinion drive gap, comprise box body of speed reducer, reductor, servomotor, Mobile Slide, hinge axis, gland and clearance adjustment mechanism, box body of speed reducer is installed on Mobile Slide, be fixed with base plate and support arm on box body of speed reducer, hinge axis is installed between Mobile Slide and gland, gland is installed on a hinge axis gripper shoe, the hinge axis gripper shoe is installed on Mobile Slide, reductor is installed on box body of speed reducer, servomotor is installed on reductor, gear is assemblied on reductor, described clearance adjustment mechanism, comprise slider block, adjust base.Slider block is assemblied on Mobile Slide, is equiped with on slider block to adjust screw rod, spring and slide bar, is equiped with steel ball between slide bar and support arm, adjusts be equiped with locking nut on base and adjust screw.
Operation principle:
Two assemblings of above-mentioned parts one and parts are completed and confirm to assemble errorless after, can enter into the drive gap adjustment link; When confirm drive gap large or hour, locking nut is unclamped, adjust screw rod and adjust screw with the allen wrench rotation, make box body of speed reducer rotate around hinge axis, namely gear produces near tooth bar or rotatablely moving away from tooth bar around hinge axis; When confirming that drive gap is suitable, locking nut is locked.Both forward and reverse directions Mobile Slide on guide rail detects with laser interferometer positioning accuracy and the repetitive positioning accuracy that slide unit moves; When undesirable, repeat above-mentioned adjustment process when positioning accuracy and repetitive positioning accuracy, until till positioning accuracy and repetitive positioning accuracy meet the requirements.Disk spring is used for balance because the gap that rack-and-pinion machining accuracy error produces is inhomogeneous.
The present invention can make and drive the rack-and-pinion that slide unit moves and obtain suitable drive gap, thus the positioning accuracy and the repetitive positioning accuracy that make such Digit Control Machine Tool have to meet the demands, and reduce the manufacturing cost of lathe.
