CN204868910U - Balance cylinder strutting arrangement of many joints heavy load robot - Google Patents

Abstract

The utility model discloses a balance cylinder strutting arrangement of many joints heavy load robot, including a balance cylinder section of thick bamboo and swivel mount, respectively there is a balance cylinder connecting axle balance cylinder section of thick bamboo both sides, characterized by: deep groove ball bearing of suit on each balance cylinder connecting axle, deep groove ball bearing's outer lane is fixed on the swivel mount. Adopting deep groove ball bearing to be connected between this device, balance cylinder connecting axle and swivel mount, replacing the slide bearing scheme among the prior art with the deep groove ball bearing scheme, because of deep groove ball bearing limit speed, bearing capacity want high than slide bearing, it is on the weak side to solve slide bearing bearing capacity in the robot, the fast problem of wear and tear, and the cost of reduction use middle and later periods change maintenance has improved the robot reliability.

Description

Multi-joint heavy load robot compensating cylinder bracing or strutting arrangement

Technical field

The utility model relates to a kind of multi-joint heavy load robot compensating cylinder bracing or strutting arrangement.

Background technology

In multi-joint heavy load robot, compensating cylinder is indispensable part, it is mainly used to the load torque balancing J2 axle joint, reduce joint to the demand of power, thus power can be selected little, cheap motor, reaches the object of energy-saving consumption-reducing, can not reduce again the acceleration of joint of robot simultaneously.

At present, the supporting construction that compensating cylinder generally uses, for install sliding bearing additional in compensating cylinder cylinder barrel both sides, by installing the form of connecting axle on robot swivel base, realizing balance support cylinder and reaching the object that compensating cylinder in robot kinematics swings thereupon.Due to the bronze material that sliding bearing many employings quality is more weak, in use sliding bearing abrasion, need often to change sliding bearing, the maintenance needed frequently is used for later stage robot.And sliding bearing bearing capacity is more weak, the application of heavy load robot show more obvious.

Utility model content

Technical problem to be solved in the utility model, is the defect overcoming prior art existence, proposes a kind of multi-joint heavy load robot compensating cylinder bracing or strutting arrangement.Adopt deep groove ball bearing to replace original sliding bearing, effectively reduce wear and reduce operation and maintenance cost, improve robot reliability.

The utility model multi-joint heavy load robot compensating cylinder bracing or strutting arrangement, comprises balance cylinder barrel and swivel base, and respectively there is a compensating cylinder connecting axle balance cylinder barrel both sides; It is characterized in that: each compensating cylinder connecting axle is set with a deep groove ball bearing, and the outer ring of deep groove ball bearing is fixed on swivel base.

This device, compensating cylinder connecting axle is connected with adopting deep groove ball bearing between swivel base, sliding bearing scheme of the prior art is replaced by deep groove ball bearing scheme, because deep groove ball bearing limit speed, bearing capacity are higher than sliding bearing, sliding bearing bearing capacity in robot can be solved on the weak side, the problem of quick abrasion, reduces the use procedure middle and later periods and changes the cost safeguarded, improve robot reliability.

Accompanying drawing explanation

Fig. 1 is the utility model multi-joint heavy load robot compensating cylinder support device structure schematic diagram (profile).

Fig. 2 is the partial enlarged drawing of Fig. 1.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further.

Shown in following Fig. 1,2, multi-joint heavy load robot compensating cylinder bracing or strutting arrangement, compensating cylinder connecting axle 4 is arranged on the both sides of balance cylinder barrel 7, and compensating cylinder connecting axle 4 is set with a bearing inner sleeve 5, and bearing inner sleeve 5 is fixing on compensating cylinder connecting axle 4 with screw.The inner ring of deep groove ball bearing 1 is fixed on bearing inner sleeve 5, by circlip for shaft 3 axial location outside deep groove ball bearing 1.The outer ring of deep groove ball bearing 1 is fixed on swivel base 6, is realized the mutual rotation of balance cylinder barrel 7 and swivel base 6 by deep groove ball bearing 1.The bearing inner sleeve 5 that compensating cylinder connecting axle 4 is installed is convenient to deep groove ball bearing 1 bearing removal.Whole compensating cylinder part, in the position, deep groove ball bearing outer ring in left side, is equipped with left end cover 2, prevents axial float.Deep groove ball bearing 1 is fixed on compensating cylinder connecting axle 4 by bearing inner sleeve 5, is convenient to dismounting.

The utility model adopts deep groove ball bearing scheme to replace original sliding bearing scheme, because deep groove ball bearing limit speed, bearing capacity are higher than sliding bearing, sliding bearing bearing capacity in robot can be solved on the weak side, the problem of quick abrasion, reduce the use procedure middle and later periods and change the cost safeguarded, improve robot reliability.
