Abstract

The utility model discloses a rotating device for manipulator, including adopting eccentric mode to fix connecting axle on the mounting panel, installing at the epaxial bearing of connecting. The utility model discloses in the use, if the bearing needs to be changed, can directly knock out from the connecting axle, the part can reuse. Meanwhile, the connecting shaft and the mounting plate fixing hole are of an eccentric positioning structure, so that the connecting shaft can be prevented from rotating when the matching clearance between the connecting shaft and the mounting plate hole is large.

Description

Rotating device for manipulator

Technical Field

The utility model belongs to the manipulator, concretely relates to rotating device that manipulator used.

Background

The manipulator is a clamping and carrying instrument in an automatic workstation, belongs to basic laboratory equipment, and is widely applied to the fields of life science, medicine, chemistry, environmental protection and the like. Along with the development of the market, the recruitment is more and more difficult and the manual operation is easy to make mistakes, so that all hospitals need to replace the manual operation with a full-automatic centrifugal system, and the efficiency and the safety performance are improved. Original manipulator slewing mechanism generally adopts from driving wheel, bearing, connecting axle to realize the motion displacement, and this structure is high with the machining precision requirement, and difficult assembly, and the processing error can lead to from the driving wheel and the bearing tight fit assembly back, if follow-up bearing appears unusually to need changing, the bearing is difficult to take out the change basically, causes overall structure to scrap and change.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the defect to prior art, provide a simple structure, the rotating device that the manipulator that conveniently assembles and dismantle was used.

Realize the utility model discloses the technical scheme that the purpose was adopted as follows:

the utility model provides a rotating device for manipulator, including adopting eccentric mode to fix the connecting axle on the mounting panel, install the bearing on the connecting axle.

The connecting shaft is fixedly locked on the mounting plate through a screw, the number of the bearings is 2, and a flat washer elastic washer is arranged between the bearing and the head of the screw.

Advantageous effects

The utility model discloses in the use, if the bearing needs to be changed, can directly knock out from the connecting axle, the part can reuse. Among the current rotating device, the bearing outer lane has from whole transmission of driving wheel outsourcing, if the bearing needs to be changed, the bearing can not pull down basically, causes whole structure to scrap the processing, and connecting axle and mounting panel fixed orifices adopt eccentric location structure simultaneously, can prevent when connecting axle and mounting panel hole fit clearance are big, the connecting axle rotates.

The technical scheme of the utility model is further explained in the following with the attached drawings.

Detailed Description

See fig. 1, fig. 2, the utility model provides a rotating device for manipulator, including adopting eccentric mode to fix connecting axle 1 on mounting panel 2, install bearing 3 on connecting axle 1, connecting axle 1 is fixed the locking on mounting panel 2 through hexagon socket head cap screw 6, bearing 3 is 2 together for the stack, is equipped with plain washer 4 spring washer 5 between bearing 3 and hexagon socket head cap screw 6's head.

See fig. 1-4, the utility model discloses during the application, install synchronizing wheel motor 15 on mounting panel 2, fix arm mount 14 to mounting panel 2 on, arm 9 that is equipped with linear guide 13 is fixed to arm mount 14 through the guide block 16 with linear guide 13 complex, hold-in range 8 is established at synchronizing wheel motor 15's synchronizing wheel 7 with the utility model discloses a 2 on the bearing 3, its trend is as shown in fig. 3, 4, after bearing 3 from above bypasses earlier, bypass synchronizing wheel 7 on synchronizing wheel motor 15, bypass bearing 3 below again, be connected to respectively on fixing the hexagon socket head cap screw 10 on the fixed plate 11 of arm 9 upper and lower extreme with belt clamping device 12 with the both ends of hold-in range 8, adjust hexagon socket cap screw 10 and can be taut with hold-in range 8, when synchronizing wheel motor 15 during operation, synchronizing wheel 7 drive hold-in range 8 is just reversing, hold-in range 8 passes through the utility model discloses the rotation direction of bearing 3 drives arm 9 and leads the nature of the line that it leads through on to lead The matching of the rail 13 and the guide block 16 realizes the up-and-down movement of the arm 9.

Claims

1. A rotating device for a manipulator is characterized by comprising a connecting shaft fixed on an installation plate in an eccentric mode and a bearing arranged on the connecting shaft; the connecting shaft is fixedly locked on the mounting plate through a screw, the number of the bearings is 2, and a flat washer elastic washer is arranged between the bearing and the head of the screw.
