Abstract
A mini-type electric push rod device special for a robot overcomes defects in the prior art, and comprises an internal thread push rod, a locking shell, a screw and a stepping motor. The mini-type electric push rod device special for the robot is characterized in that the locking shell is arranged on the internal thread push rod in a sleeved mode, an flexible port of the locking shell is in a square shape, and the cross section of the push rod part of the internal thread push rod is also in a square shape. Threads of the screw are matched with those of the internal thread push rod. When the screw rotates, the internal thread push rod can not rotate relatively because of being limited by the locking shell and can only move longitudinally, and the screw rotates to drive the internal thread push rod to move flexibly. A rotating shaft of the stepping motor is connected with one head, without threads, of the screw in a fixed mode. When the stepping motor rotates, the screw rotates along with a rotator of the stepping motor. The screw is provided with power by the stepping motor, because the stepping motor can accurately control rotation angles, rotation turns and rotation speed of the rotator. The mini-type electric push rod device special for the robot is simple in structure, changeable in size, and capable of achieving accurate control of micron order.
Description
Technical field
The utility model relates to the push rod field, particularly the special-purpose miniature electromotive handspike device of a kind of robot.
Background technology
Along with the extensive research and development of robot, the modern machine people is towards direction high speed developments such as intelligent, control precision, microminiaturizations.Majority can use push rod in the development process of robot.Usually generally all adopt hydraulic pressure and pneumatic two types at the push rod of industrial use, although hydraulic push rod and air-leg can provide larger operational forces in real work, yet in the exploitation of robot, often do not need to provide so large operational forces.Utilize hydraulic pressure and pneumatic push rod to need more complicated device, be difficult to the volume-diminished with push rod, and at high temperature with wait the push rod that should not use hydraulic pressure and pneumatic operation principle in the environment under water.Being difficult to reach a higher degree aspect the accuracy of the exploitation of robot and control, have overflow phenomena, and control device too complex technology have relatively high expectations.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of prior art, and the special-purpose miniature electromotive handspike device of a kind of robot that provides.
Technical scheme:
The design mainly is comprised of internal thread push rod, lock enclosure, screw rod, stepper motor.Lock enclosure is enclosed within on the internal thread push rod, and the telescopic mouth of lock enclosure is square, and the pusher section cross section of internal thread push rod also be square, lock enclosure so that the internal thread push rod can only the longitudinal extension campaign can not rotate with respect to lock enclosure.Screw flight and internal thread push rod threaded engagement when bolt rotary, because the locked shell restriction of internal thread push rod can't relatively rotate, can only be done lengthwise movement, and bolt rotary promotes the internal thread push rod and does stretching motion.Stepping motor rotating shaft and screw rod do not have threaded one to fix, when stepper motor rotates, screw rod rotates with stepping motor rotor, provide power to screw rod by stepper motor, because stepper motor can accurately be controlled rotational angle, the rotation number of turns of rotor and rotate speed, therefore realizes the length of accurately controlling the elongation of internal thread push rod and shortening.
Beneficial effect: the design is simple in structure, and size is changeable, can realize micron-sized accurate control.Material environment friendly, non-environmental-pollution, the recyclable recycling of material.Install and simply need not special transformation, parts are few, can realize large-scale production.

Among the figure: 1. internal thread push rod, 2. lock enclosure, 3. screw rod, 4. stepper motor.
The specific embodiment
Such as Fig. 1-shown in Figure 7, the design mainly is comprised of internal thread push rod, lock enclosure, screw rod, stepper motor.Lock enclosure is enclosed within on the internal thread push rod, and the telescopic mouth of lock enclosure is square, and the pusher section cross section of internal thread push rod also be square, lock enclosure so that the internal thread push rod can only the longitudinal extension campaign can not rotate with respect to lock enclosure.Screw flight and internal thread push rod threaded engagement when bolt rotary, because the locked shell restriction of internal thread push rod can't relatively rotate, can only be done lengthwise movement, and bolt rotary promotes the internal thread push rod and does stretching motion.Stepping motor rotating shaft and screw rod do not have threaded one to fix, when stepper motor rotates, screw rod rotates with stepping motor rotor, provide power to screw rod by stepper motor, because stepper motor can accurately be controlled rotational angle, the rotation number of turns of rotor and rotate speed, therefore realizes the length of accurately controlling the elongation of internal thread push rod and shortening.Its project organization is simple compact attractive in appearance, can be designed to as required different size, and integral diameter can reach several millimeters.
