Description
Technical field
The utility model relates to a kind of positioning and locking device of multi-joint mechanical arm, particularly the multi-joint mechanical arm quick-locking device.
Background technology
At present, domestic multi-joint mechanical arm generally adopts the form of damping arm or utilizes the location and the locking of inserting the form realization mechanical arm of selling directly to households between two parts of relative motion.Though the damping arm can be realized the location of mechanical arm fast, the internal structure more complicated, and the load that ordinary circumstance can be born is also less; Though direct selling can guarantee mechanism and locate that it moves axially easily under external force and comes off, and can not guarantee the work that mechanism is safe and reliable, and can not realize the quick location and the locking of whole multi-joint mechanical arm on the direction of motion.Utilize single knob to tighten the device that can make a whole set of mechanical arm positioning and locking though have abroad, internal structure is quite complicated, the very difficult realization of dismounting back secondary installing, and cost an arm and a leg, be unsuitable for promoting.
Summary of the invention
According to background technology, the purpose of this utility model is to avoid existing multi-joint mechanical arm to be difficult for the deficiency of locating and locking fast, provide a kind of multi-joint mechanical arm that can not only make to realize location and locking fast and effectively, and the load that can carry is relatively large, can guarantee the quick positioning and locking device of multi-joint mechanical arm of whole mechanical arm safety, reliably working.
To achieve these goals, the utility model is achieved through the following technical solutions:
The quick positioning and locking device of a kind of multi-joint mechanical arm, mainly form by winding device (1) and multi-joint mechanical arm (2), wherein: winding device (1) is made up of knob (11), upper spring seat (12), holddown spring (13), spring cabin (14), screw rod (15) and lower spring cup (16), holddown spring (13) suit inserting spring cabin (14), and insert upper spring seat (12) simultaneously and be shaped in the lower spring cup (16) of screw rod (15), knob (11) is spirally connected by upper spring seat (12), spring cabin (14) and screw rod (15) on the lower spring cup (16); Multi-joint mechanical arm (2) is made up of two groups of rod members of structural similarity, every group of rod member mainly by upper spring seat (12) or lower spring cup (16), with the hollow arm (21) of its one, regulate in bar (22), bulb cabin (23), bulb (24) and ball-head cover (25) form, bar (22) places hollow arm (21) in regulating, bulb (24) is inserted in the bulb cabin (23), ball-head cover (25) overlapped bulb (24) and bulb cabin (23) are spirally connected with hollow arm (21), and bulb (24) and bulb cabin (23) are held tightly.
Owing to adopted technique scheme, the utlity model has following advantage and effect:
1, after the utility model regulates mechanical arm, only just can make multi-joint mechanical arm location and locking fast fast by screwing a knob.
2, the utility model is simple in structure, and is safe and reliable.

The specific embodiment
Illustrate by Fig. 1 and Fig. 2, the quick positioning and locking device of a kind of multi-joint mechanical arm, mainly form by winding device 1 and multi-joint mechanical arm 2, wherein: winding device 1 is made up of knob 11, upper spring seat 12, holddown spring 13, spring cabin 14, screw rod 15 and lower spring cup 16, holddown spring 13 suit inserting spring cabins 14, and insert upper spring seat 12 simultaneously and be shaped in the lower spring cup 16 of screw rod 15, knob 11 is spirally connected by the screw rod 15 on upper spring seat 12, spring cabin 14 and the lower spring cup 16; Multi-joint mechanical arm 2 is made up of two groups of rod members of structural similarity, every group of rod member mainly by upper spring seat 12 or lower spring cup 16, with the hollow arm 21 of its one, regulate in bar 22, bulb cabin 23, bulb 24 and ball-head cover 25 form, bar 22 places hollow arm 21 in regulating, bulb 24 is inserted in the bulb cabin 23, ball-head cover 25 overlapped bulb 24 and bulb cabin 23 is spirally connected with hollow arm 21, and bulb 24 and bulb cabin 23 are held tightly.
During use, at first regulate the length of the interior bar 22 of adjusting of multi-joint mechanical arm 2, and place hollow arm 21, Place head 24 is in bulb cabin 23, can arbitrarily rotate adjusting between the two, the suit ball-head cover 25 then, and be spirally connected with hollow arm 21 heads, bulb 24 promptly is locked in the position is set, mechanical arm does not have the side in bulb cabin and last, lower spring cup 12, put into steel ball between 16, after adjusting multi-joint mechanical arm 2 reaches the target location, can screw knob 11 compression holddown springs 13, this moment, steel ball did not have the side jam-packed in bulb cabin to mechanical arm, so just can hold out against interior bar 22, and then make bulb cabin 23 hold bulb 24 tightly, finally can realize multi-joint mechanical arm location and locking.
Other knows, after using a period of time because mechanical wear, contact effect between bulb 24 and the bulb cabin 23 may weaken, thereby the positioning and locking effect of the whole mechanical arm of image, can increase by the length of bar 22 in regulating this moment and compress effect, because of being to be threaded between bar 22 in regulating and the bulb cabin 23, can change the length of bar 22 in the whole adjusting by regulating the length that is threaded between the two.
Know that again because the application scenario difference, the rotating range of multi-joint mechanical arm bulb 24 may be different, can play 26 guiding and the spacing effects of ball-joint arm this moment by leaving corresponding gap on the ball-head cover 25.
