When the driving device forms an external force for driving the sliding member 41 to move, the horizontal limiting member 43 is separated from the horizontal rotating mechanism, and at the same time, the vertical limiting member 44 is separated from the vertical rotating mechanism. At this time, since the central spindle 22 and the central spindle 22 are connected together and the rotation fixing base is connected together, when the central spindle 22 performs horizontal rotation adjustment, the rotation fixing base can be driven to perform horizontal rotation adjustment at the same time, and further, since the rotation fixing base is connected with the vertical rotation mechanism, the vertical rotation mechanism can be driven to perform horizontal rotation adjustment. In addition, the vertical rotating mechanism can be used for vertical rotation adjustment, so that the mechanical arm can be used for horizontal rotation and vertical rotation position adjustment.
The working principle of the embodiment is as follows: the mechanical arm is provided with the adjusting mechanism, and the adjusting mechanism can simultaneously realize limit adjustment on the horizontal rotating mechanism and the vertical rotating mechanism. Through setting up slider 41, restoring pieces 42, horizontal locating part 43 and vertical locating part 44, when slider 41 does not have the exogenic action under the effect of restoring pieces 42, horizontal locating part 43 locking horizontal rotary mechanism, vertical locating part 44 locking vertical rotary mechanism, lock the arm like this and make things convenient for the user to carry out stay cord 5 training. When the user needs to adjust the position of the mechanical arm, the user controls the driving device through the switch, and an external force for driving the sliding part 41 to move is formed by the driving device, so that the horizontal limiting part 43 is separated from the horizontal rotating mechanism, and meanwhile, the vertical limiting part 44 is separated from the vertical rotating mechanism. Therefore, the user controls the switch by one hand, pulls the mechanical arm by the other hand to adjust the position of the mechanical arm, and the mechanical arm is very conveniently adjusted to a proper position. If the switch is released, the sliding member 41 returns to the condition without external force, the horizontal limiting member 43 locks the horizontal rotating mechanism, the vertical limiting member 44 locks the vertical rotating mechanism under the action of the resetting member 42, so that the resetting member 42 locks the horizontal rotating mechanism and the vertical rotating mechanism of the mechanical arm again, and the user can conveniently perform training of the pull rope 5.
In this embodiment, the user pulls the pull cord 5 manually through the pull cord switch 6, and the pull cord 5 forms an external force for driving the sliding member 41 to move, so that the horizontal limiting member 43 is separated from the horizontal rotating mechanism, and at the same time, the vertical limiting member 44 is separated from the vertical rotating mechanism. Thus, the user can control the pull rope 5 by one hand and pull the mechanical arm by the other hand to adjust the position of the mechanical arm, so that the mechanical arm can be very conveniently adjusted to a proper position.
Example 2
The point of difference from example 1 is that: the resetting piece 42 is an electromagnetic clutch device, a magnetic attraction device, a rubber piece or a silica gel piece.
As a further explanation of this embodiment, the sliding member 41 is connected to a driving device (not shown in the drawing), and an external force generated by the driving device is used to drive the sliding member 41 to move, so that the horizontal limiting member 43 is separated from the horizontal rotating mechanism, and the vertical limiting member 44 is separated from the vertical rotating mechanism, on the basis of the above-mentioned change of the resetting member 42 or the adoption of the resetting member 42 of the embodiment 1. The driving device can be an existing linear motor driving device, a screw nut driving device, an electromagnetic clutch driving device or a magnetic attraction driving device.
As a further explanation of the present embodiment, a clutch device (not shown) is connected to the driving device, and the clutch device is used to connect and disconnect the driving device to and from the slider 41.
The working principle of the embodiment is as follows: the mechanical arm drives the adjusting mechanism to move through the driving device and the clutch device by the existing linear motor driving device, the screw nut driving device, the electromagnetic clutch driving device or the magnetic attraction driving device. In addition, by arranging an adjusting mechanism, the limiting adjustment of the horizontal rotating mechanism and the vertical rotating mechanism can be realized at the same time by the adjusting mechanism. Through setting up slider 41, restoring pieces 42, horizontal locating part 43 and vertical locating part 44, when slider 41 does not have the exogenic action under the effect of restoring pieces 42, horizontal locating part 43 locking horizontal rotary mechanism, vertical locating part 44 locking vertical rotary mechanism, lock the arm like this and make things convenient for the user to carry out stay cord 5 training. When the user needs to adjust the position of the mechanical arm, the user controls the driving device through the switch, and an external force for driving the sliding part 41 to move is formed by the driving device, so that the horizontal limiting part 43 is separated from the horizontal rotating mechanism, and meanwhile, the vertical limiting part 44 is separated from the vertical rotating mechanism. Therefore, the user controls the switch by one hand, pulls the mechanical arm by the other hand to adjust the position of the mechanical arm, and the mechanical arm is very conveniently adjusted to a proper position. If the switch is released, the sliding member 41 returns to the condition without external force, the horizontal limiting member 43 locks the horizontal rotating mechanism, the vertical limiting member 44 locks the vertical rotating mechanism under the action of the resetting member 42, so that the resetting member 42 locks the horizontal rotating mechanism and the vertical rotating mechanism of the mechanical arm again, and the user can conveniently perform training of the pull rope 5.
In this embodiment, the user drives the sliding member 41 to move by means of a control switch (not shown), so that the horizontal limiting member 43 is separated from the horizontal rotating mechanism, and at the same time, the vertical limiting member 44 is separated from the vertical rotating mechanism. Therefore, one hand of the user acts on the control switch, and the other hand pulls the mechanical arm to adjust the position of the mechanical arm, so that the mechanical arm can be conveniently adjusted to a proper position.
When the driving device is damaged or the robot arm is powered off, the user switches to the manual mode of embodiment 1 by controlling the clutch device to place the driving device in a separated state from the slider 41. Thus, the user pulls the pull rope 5 manually through the pull rope switch 6, the pull rope 5 forms an external force for driving the sliding piece 41 to move, so that the horizontal limiting piece 43 is separated from the horizontal rotating mechanism, and meanwhile, the vertical limiting piece 44 is separated from the vertical rotating mechanism. Thus, the user can control the pull rope 5 by one hand and pull the mechanical arm by the other hand to adjust the position of the mechanical arm, so that the mechanical arm can be very conveniently adjusted to a proper position. Therefore, the clutch device is arranged, so that the adjustment mechanism of the mechanical arm can be conveniently switched between the manual mode and the automatic switching mode, and when the adjustment mechanism of the mechanical arm is in the automatic mode and is in the power-free mode or the driving device fails, the adjustment mechanism can be manually switched into the manual mode by one key, and the normal use of a user is not influenced.
The mechanical arm for body building has the characteristics of simple structure, low cost, long service life, easiness in installation and maintenance and the like. And when no electricity exists or the driving device fails, the switching between the manual mode and the automatic switch mode of the adjusting mechanism of the mechanical arm can be conveniently realized through the clutch device, and the normal use of a user is not influenced, so that the mechanical arm for body building with automatic switch and manual compatible dual-purpose is provided for the user.
