Abstract
The utility model discloses a compact mechanical self-locking rotary joint, which comprises a joint shell, a motor, a mechanical arm, a planetary speed reducer, a worm gear and a worm. The mechanical arm is arranged on the joint shell, an output shaft of the motor is connected with an input shaft of the planetary speed reducer, an output shaft of the planetary speed reducer is connected with one end of the worm, the worm is provided with engagement teeth, the worm gear is connected with the engagement teeth of the worm in an engagement manner, and a worm gear shaft of the worm gear is used as a power output end. By changing the traditional transmission mode, the weight of the mechanical arm is reduced, therefore, the power of the motor is reduced, and the endurance time of a battery is extended. Moreover, the structure of the joint is more compact, modularization can be realized easily, and the appearance is more attractive. The motor is arranged in the mechanical arm and can be protected easily, and the service life of the motor can be prolonged. Moreover, no harmonic speed reducer is used, so the manufacturing cost is decreased.
Description
Technical field
The utility model relates to a kind of mechanical self-latching rotary joint, particularly relates to a kind of compact type mechanical self-latching rotary joint.
Background technique
The conventional mechanical devices structure adopts the scheme of motor worm type of reduction gearing harmonic speed reducer, input harmonics retarder after motor slows down through worm type of reduction gearing, driving device arm motion then.Traditional mechanical joint structure can realize basic spinfunction, but has following shortcoming: 1. the traditional scheme volume is bigger, and weight is heavier, causes driving force to increase, and the battery flying power descends; 2. motor receives ambient conditions influences such as rainwater easily.3. it is big to take up room, and outward appearance is attractive in appearance inadequately; 4. cost is high relatively.The reason that traditional mechanical joint structure produces above shortcoming is following: 1. structure is not compact, and excess weight is arranged, and volume is big; 2. electric machine external is exposed in the atmosphere; 3. traditional scheme will make transmission device such as motor place the inner difficulty in joint very big; 4. flexible member-the flexbile gear of harmonic wave speed reducing machine self has short defective in working life, and makes relative complex.
The model utility content
The purpose of the utility model is that a kind of low cost of manufacture, motor long service life, in light weight and compact type mechanical self-latching rotary joint that volume is little are provided in order to address the above problem.
The utility model is realized through following technological scheme:
A kind of compact type mechanical self-latching rotary joint; Comprise joint housing, motor, mechanical arm; Said mechanical arm is installed on the said joint housing, and said mechanical self-latching rotary joint also comprises planetary reducer, worm gear and worm screw, and the output shaft of said motor is connected with the input shaft of said planetary reducer; The output shaft of said planetary reducer is connected with the end of said worm screw; Said worm screw is provided with grinding tooth, and the grinding tooth on said worm gear and the said worm screw is connected with a joggle, and the worm-wheel shaft of said worm gear is a clutch end.
Through changing traditional actuating mode, reduce the weight of mechanical arm, thereby reduced power of motor, prolong battery life, and make articulation structure compact more, be easy to realize modularization, profile is more attractive in appearance.
Further improvement as the utility model is that said motor is installed in the arm pipe of said mechanical arm.Electric machine built-in in mechanical arm, is easy to protect motor, prolongs electrical machinery life
The beneficial effect of the utility model is:
Through changing traditional actuating mode, reduce the weight of mechanical arm, thereby reduced power of motor, prolong battery life, and make articulation structure compact more, be easy to realize modularization, profile is more attractive in appearance; Electric machine built-in in mechanical arm, is easy to protect motor, prolongs electrical machinery life, in addition, the utility model does not use harmonic speed reducer, has reduced manufacture cost.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify:
To shown in Figure 4, the utility model compact type mechanical self-latching rotary joint comprises joint housing 1, mechanical arm 2, motor 3, planetary reducer 4, worm screw 5 and worm gear 6 like Fig. 1; Mechanical arm 2 is installed on the joint housing 1; The output shaft of motor 2 is connected with the input shaft of planetary reducer 4, and the output shaft of planetary reducer 4 is connected with the end of worm screw 5, and worm screw 5 is provided with grinding tooth; Grinding tooth on worm gear 6 and the worm screw 5 is connected with a joggle, and the worm-wheel shaft 7 of said worm gear 6 is a clutch end.The utility model has reduced the weight of mechanical arm 2, thereby has reduced power of motor through changing traditional actuating mode, prolongs battery life, and makes articulation structure compact more, is easy to realize modularization, and profile is more attractive in appearance.
It should be noted last that above embodiment is only unrestricted in order to the technological scheme of explanation the utility model.Although the utility model is specified with reference to embodiment; Those of ordinary skill in the art is to be understood that; The technological scheme of the utility model is made amendment or is equal to replacement; The spirit and the scope that do not break away from the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
