Abstract

The utility model discloses a mechanical arm which comprises a reducer. The reducer is a worm gear reducer. A worm gear input shaft is arranged at the upper end of the reducer and is connected with a worm gear. A worm which is matched with the worm gear and is arranged inside the reducer extends out of the front end face of the reducer. A driving gear is arranged on the worm. A driven gear is arranged on the front end face of the reducer. The lower end of the driving gear and the lower end of the driven gear are respectively connected with a connecting arm. The lower end of each connecting arm is connected with a mechanical claw through a pin. The upper end of each mechanical claw is further connected with a supporting rod through a pin. The other end of each supporting rod is connected at the lower end of the front end face of the reducer. When the mechanical arm is used, a motor drives the worm gear input shaft to rotate, motive power is transmitted to a worm gear output shaft through the speed reducing function of the reducer, and the driving gear and the driven gear rotate at the same time so as to drive the mechanical claws to open and close. The mechanical arm is simple in structure and convenient to operate, and greatly improves working efficiency.

Description

A kind of manipulator

Technical field

The utility model relates to a kind of manipulator.

Background technology

In the modern production process, a lot of parts need to carry out high temperature process to it, and these high temp objects need to be transported and to its further processing, namely need some instruments to come clamping, in the traditional handicraft, there is the fire tongs of employing that object is removed transhipment, its inefficiency, and be easy to the danger that causes the staff to scald, and in the modern science and technology, need a kind of can safeguard work efficient, the instrument that can guarantee personal safety again replaces manually-operated.

The utility model content

For solving the deficiencies in the prior art, technical problem to be solved in the utility model provides a kind of simple in structure, easy to operate manipulator.

The utility model is achieved through the following technical solutions:

A kind of manipulator of the present utility model, described manipulator comprises decelerator, described decelerator is worm type of reduction gearing, described decelerator upper end is equipped with the worm gear power shaft, described worm gear power shaft is connected with worm gear, worm screw with worm wheel in the described decelerator stretches out the decelerator front end face, on the described worm screw driving gear is installed, on the described decelerator front end face driven gear is installed also, described driving gear and driven gear lower end all are connected with linking arm, described linking arm lower end is connected with gripper by pin, and described gripper upper end also is connected with pole by pin, and the described pole other end is connected to decelerator front end face lower end by pin.

Further, described driving gear and driven gear radius equate, and described driving gear and driven gear are intermeshing.

Further, described linking arm is integrated with driving gear and driven gear respectively.

Further, described gripper inboard is provided with tread plate.

The beneficial effects of the utility model are: when using the utility model, driven by motor worm gear power shaft rotates, the decelerating effect by decelerator again, to the worm screw output shaft, driving gear and driven gear rotate simultaneously with transmission of power, and the driving mechanical pawl is realized moving process, it is simple in structure, reasonable in design, easy to operate, greatly increase work efficiency.

Description of drawings

In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.

Fig. 1 is the structural representation of a kind of manipulator of the present utility model.

The specific embodiment

As shown in Figure 1, a kind of manipulator of the present utility model, described manipulator comprises decelerator 6, described decelerator 6 is worm type of reduction gearing, described decelerator 6 upper ends are equipped with worm gear power shaft 7, described worm gear power shaft 7 is connected with worm gear, worm screw 8 with worm wheel in the described decelerator 6 stretches out decelerator 6 front end faces, on the described worm screw 8 driving gear 9 is installed, on described decelerator 6 front end faces driven gear 5 is installed also, described driving gear 9 and driven gear 5 lower ends all are connected with linking arm 3, described linking arm 3 lower ends are connected with gripper 2 by pin 4, described gripper 2 upper ends also are connected with pole 1 by pin 4, and described pole 1 other end is connected to decelerator 6 front end face lower ends by pin 4.

A kind of optimal way of the present utility model, described driving gear 9 and driven gear 5 radiuses equate, and described driving gear 9 and driven gear 5 are intermeshing.

A kind of optimal way of the present utility model, described linking arm 3 are integrated with driving gear 9 and driven gear 5 respectively.
