Pneumatic abrasive belt machine for robot automatic polishing

Technical Field

The utility model relates to an automatic pneumatic abrasive band machine for polishing of robot belongs to the technical field of polishing.

Background

Grinding dust is harmful to health, grinding time is long for large-sized workpieces with special-shaped surfaces, grinding workers are prone to fatigue, consistency of surface quality of the workpieces is difficult to guarantee due to manual grinding, and especially when requirements on the surface quality of the workpieces are high, such as stirring rods used in food and pharmaceutical industries, the conditions promote development of the robot grinding industry. The robot polishing mainly has two modes, one mode is that a polishing tool is fixed, the robot grabs a workpiece to move, and the polishing tool is fixed; the other is the opposite, where the grinding tool is gripped by the robot and the workpiece is fixed in position. For some large workpieces, the workpiece weight is far beyond the robot load, so the latter grinding method is used more often. For such working conditions, in order to avoid damage caused by rigid contact between the grinding tool at the end of the robot and the workpiece, the end of the robot and the grinding tool are usually connected by a force control device. In the grinding process, the track planning made on the basis of theoretical model workpieces often cannot completely conform to the real object, so that the flexibility brought by the force control device and the compensation effect on the track deviation are very critical. However, the force control device is high in cost and complex in control link, and the increase of the force control device results in a long overall structure of the tail end of the robot, and the robot cannot flexibly move in a complex space, so that the polishing efficiency is low.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 and 2, the pneumatic belt sander for robot automated grinding in the present embodiment includes a mounting base 1, and a pneumatic motor 3 is disposed in the mounting base 1. The side of the mounting seat 1 is provided with a roller bracket 5, and a driving shaft 10, a driven shaft 11 and a roller 9 are erected on the roller bracket 5 and are arranged in parallel. An output shaft of the pneumatic motor 3 penetrates through the mounting seat 1 and is connected with a driving shaft 10 through a plum coupling 4, a driving wheel is arranged on the driving shaft 10, a driven wheel is arranged on a driven shaft 11, and an abrasive belt 6 is sleeved among the driving wheel, the driven wheel and the roller 9. The other side of mount pad 1 sets up pneumatic quick change device 2, and the trachea of pneumatic motor 3 passes through pneumatic quick change device 2 to be connected with the air supply, and the air supply lets in the trachea of pneumatic motor 3 through pneumatic quick change device 2, and the rotation of 3 output shafts of pneumatic motor drives driving shaft 10, action wheel rotation for cylinder 9 with, driven shaft 11, rotate from the driving wheel synchronization, drive abrasive band 6 rotates, realizes that abrasive band 6 polishes to the piece of polishing.

The roller bracket 5 is symmetrically provided with adjusting grooves 8 which are obliquely arranged, a tension wheel 7 is erected in the adjusting grooves 8 and fixed on the roller bracket 5 through a nut, and the tension wheel 7 tensions the abrasive belt 6. When nuts at two ends of the tensioning wheel 7 are loosened, the tensioning wheel 7 slides to the lowest position along the adjusting groove 8, the abrasive belt 6 is sleeved on the tensioning wheel 7, the rear tensioning wheel 7 moves along the adjusting groove 8, the abrasive belt 6 is placed in the middle of the roller 9, and the nuts are screwed later, so that the tensioning and installation of the abrasive belt 6 are completed.

The tension wheel 7 and the driven wheel are both cams, and the driving wheel is a flange wheel. The two cams are combined with the edge blocking wheel, so that the abrasive belt has certain degree of freedom in transverse movement when the abrasive belt works. The abrasive belt can move left and right without falling off by utilizing the characteristic that the abrasive belt does not move up and down on the cam, so that the stability of the grinding work is greatly improved.

The flexible cladding of abrasive band in this application, very be applicable to face of cylinder or the arc surface and polish, benefit from the flexibility of self, the abrasive band has certain self-adaptability when pressing in the curved surface, can effectively strengthen the area of contact that the curved surface was polished, improves efficiency of polishing, has still played the guard action to the shape of curved surface simultaneously, the condition of grinding out the edge can not appear.

The pneumatic motor drives the driving wheel, the abrasive belt, the roller and the driven wheel to rotate, and compared with a motor with the same power, the pneumatic motor is light in size and weight, does not need to be connected with an encoder or a servo controller, and is simple in control structure. Therefore, the end structure and the connecting line of the robot are simplified, the quick change is convenient, and the load requirement on the robot is reduced.

The pneumatic motor works with overload protection. When the load of the pneumatic motor is too large, the speed can be reduced in a self-adaptive manner, and when the overload is relieved, the pneumatic motor can automatically recover to a normal working state without damage. When metal is polished, the characteristic can be utilized as a workpiece surface protection means. The internal gas circulation of the pneumatic motor can be self-cooled, the fatigue problem is not easy to generate, and the maintenance and repair time is reduced.
