Abstract
The utility model discloses a mechanical arm. The mechanical arm comprises a rotating base, the upper side of the base is connected with a movable small arm through a connection rod, the mechanical arm further comprises a large arm, the large arm is parallel to the connection rod and meanwhile is connected with the base and the small arm, and a first servo motor and a second servo motor are arranged on two sides of the lower end of the large arm respectively. According to the novel mechanical arm, working flexibility and stability are improved, movement accuracy and movement rigidity are guaranteed, and movement errors between the base and the arms are reduced.
Description
Technical field
The utility model relates to a kind of mechanical arm.
Background technology
Mechanical arm has now been common to each mechanical field so that parts are welded, for example: automation equipment, automobile, precision optical machinery industry, traditional mechanical arm buying expenses is higher, and the supported weight of large arm and forearm is larger, stable not during actual welding, affect whole flexibility.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of new mechanical arm, has improved flexibility and the stability of work, has guaranteed motion accuracy and motion rigidity, has reduced the kinematic error between support and arm.
A mechanical arm, comprises revolution support, and support top connects a removable forearm by a connecting rod, also comprises that one is parallel with connecting rod and connect the large arm of support and forearm simultaneously, and both sides, described large arm lower end are respectively equipped with servomotor one and servomotor two.
Preferably, described forearm end cover has a limited block, and middle part cover has a cushion collar.
Preferably, described revolution support below is provided with a limit base.
The utility model provides a kind of new mechanical arm, servomotor is located to both sides, large arm lower end, can alleviate the weight of forearm and large arm, improve kinematic dexterity, and by limit base is set below support, cushion collar and limited block are set on forearm, improved positioning precision, by reliable connection, guaranteed motion accuracy and motion rigidity, reduced the kinematic error between support and arm.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.
Fig. 1 is the structural representation of the disclosed a kind of mechanical arm of the utility model embodiment.
1, revolution support 2, forearm 3, large arm 4, connecting rod 5, servomotor one
6, servomotor 27, cushion collar 8, limited block 9, limit base.
The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, a mechanical arm, comprises revolution support 1, and support 1 top connects a removable forearm 2 by a connecting rod 4, also comprise that one is parallel with connecting rod 4 and connect the large arm 3 of support 1 and forearm 2 simultaneously, described large arm 3 both sides, lower end are respectively equipped with servomotor 1 and servomotor 26; Wherein, forearm 2 end covers have a limited block 8, and middle part cover has a cushion collar 7; Revolution support 1 below is provided with a limit base 9.
The whole support 1 of driven by servomotor in revolution support 1 carries out gyration, make each arm with support 1 revolution, servomotor 1 drives large arm 3 to carry out swing, and the direct drive link 4 of servomotor 26, drives forearm 2 to carry out elevating movement according to four rod principles indirectly.
The utility model provides a kind of new mechanical arm, servomotor is located to both sides, large arm lower end, can alleviate the weight of forearm and large arm, improve kinematic dexterity, and by limit base is set below support, cushion collar and limited block are set on forearm, improved positioning precision, by reliable connection, guaranteed motion accuracy and motion rigidity, reduced the kinematic error between support and arm.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all modifications of making within spirit of the present utility model and on an equal basis conversion, within all should dropping on protection domain of the present utility model.
