Abstract
The invention discloses a high-precision small-torque feeding mechanism. The high-precision small-torque feeding mechanism comprises an outer bracket, a stepping motor, a lead screw, a common bevel gear, a bevel gear and a horizontal guide rail, wherein an inner hole of the bevel gear is provided with screw threads; the stepping motor is used for driving the common bevel gear to rotate; the common bevel gear is used for driving the bevel gear of which the inner hole is provided with screw threads to rotate; the bevel gear of which the inner hole is provided with screw threads rotates to drive the lead screw to move along the horizontal guide rail so as to realize a feeding function. The high-precision small-torque feeding mechanism disclosed by the invention is capable of realizing relatively-large-resistance horizontal feeding function by a quite small driving torque.
Description
Technical field
A kind of little moment feed mechanism of high accuracy of present invention design, mechanical field.
Background technology
In mechanical field, mainly there are ball screw framework and feed screw nut in the mechanism that gyration is converted into linear motion
Mechanism or pinion and rack, wherein pinion and rack transmission accuracy is low, produces vibration during motion；Ball screw framework and
It is desirable to higher torque when screw-nut body is directly connected with stepper motor, in order to overcome the problems referred to above, existing improvement machine
Structure is connected by key with leading screw for gear, so introduces the alignment error of gear and leading screw so that the transmission accuracy of mechanism again
Reduce.And a kind of little moment feed mechanism of high accuracy of present invention design solves when gyration is converted into linear motion, pass
Pass the problem that moment is big and transmission accuracy reduces it is achieved that the machine driving of little moment in high precision.
Content of the invention
In view of above-mentioned, it is an object of the invention to provide a kind of solve for gyration to be converted into linear motion, reduce step
During stepper motor driving moment, introduce the new mechanism of gear and the technical contradiction of leading screw alignment error.
By outside support, stepper motor, common bevel gear, the screwed bevel gear of endoporus, leading screw, level is led for this mechanism
Rail is constituted.
Stepper motor, common bevel gear, the screwed bevel gear of endoporus is fixed on outside support.
The axle of stepper motor is arranged in the axis hole of common bevel gear, and leading screw is arranged on the screwed bevel gear of endoporus
In axis hole, and with the paralleling of horizontal guide rail, horizontal guide rail level is fixed.
Drive connection：Stepper motor drives common bevel gear to rotate, and common bevel gear drives endoporus screwed cone tooth
Wheel rotates, and the screwed bevel gear of endoporus rotates and drives leading screw to move along horizontal guide rail, and tooth commonly bored by wherein stepper motor
Wheel and the gyration of endoporus screwed bevel gear generation, the screwed bevel gear of endoporus, leading screw and horizontal guide rail produce
Raw moves horizontally.
The present invention is achieved through the following technical solutions：Stepper motor drives common bevel gear to rotate so that endoporus carries spiral shell
The bevel gear of line drives leading screw to realize moving horizontally along horizontal rail by screw pair, thus realizing feed function.
Advantages of the present invention and its remarkable result：Mechanism is simple, and rotation error is little, high precision, and driving moment is little, Ke Yishi
The feed motion of existing relatively long distance.
The screwed bevel gear of endoporus and leading screw are directly connected to form screw pair by screw thread.
