Round corner polishing grinding head mechanism mounted on robot arm

Technical Field

The utility model relates to the technical field of mechanical equipment, in particular to fillet bistrique mechanism of polishing who installs on robotic arm.

Background

The conventional method for polishing the right-angle welding seam and the straight-edge radius after the metal plate welding is to use a handheld angle grinder and rotary polishing equipment or a fillet milling cutter to process most of the right-angle welding seam and the straight-edge radius. The fillet mill and the rotary type polishing equipment are labor-consuming and time-consuming, the round angle of polishing treatment cannot be guaranteed to be consistent, the round angle is excessively not smooth, and dust flies upward during polishing to cause strong damage to human bodies and the environment. The fillet milling cutter has the advantages of low processing speed, great influence of welding deformation on processing effect, obvious tool marks when the feeding speed is high, and high processing cost.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an install fillet bistrique mechanism of polishing on robotic arm which characterized in that: a connecting flange 1 in the grinding head mechanism is arranged on a rotating bottom plate 5, a first motor 2, a second motor 3 and a third motor are arranged at the lower end of the rotating bottom plate 5, the first motor 2 penetrates through the rotating bottom plate 5 to be connected with a synchronizing wheel 8, the synchronizing wheel 8 controls a driving wheel 17 arranged on a grinding head bottom plate 10 through a belt, the second motor 3 penetrates through the rotating bottom plate 5 to be connected with a hollow rotating platform 4 arranged between the rotating bottom plate 5 and a rotating connecting plate 7, a guide rail 15 is arranged on the back of the grinding head bottom plate 10, an abrasive belt tensioning plate 16 is arranged on the guide rail 15 and connected with an air cylinder 14, and a manual valve 13 is arranged on one side of the air cylinder 14.

Preferably, driven wheels 11 are provided at four corners of the sanding head base plate 10, and the sanding belt 12 is wound between the driving wheel 17 and the driven wheels 11. The beneficial effects are that: when the abrasive belt is used for polishing, the abrasive belt continuously rotates under the driving of the driving wheel, the abrasive materials in a polishing area continuously change, the whole abrasive belt can be utilized, and the utilization rate of the abrasive belt is improved.

Preferably, three proximity switches 6 are installed on the top end of the rotary base plate 5, and the proximity switches 6 are horizontal to the top end of the rotary joint plate 7. Has the advantages that: the swing amplitude of the rotary connecting plate can be effectively controlled by arranging the proximity switch, so that the limiting effect is achieved.

Preferably, a U-shaped opening is arranged at the installation position of the proximity switch 6. The beneficial effects are that: the swing amplitude of the rotary connecting plate can be adjusted in time according to the requirement of the polishing precision of the product.

Compared with the prior art, the beneficial effects of the utility model are that: the grinding head can swing according to the design requirements of products to finish fillet grinding, the grinding speed can be adjusted in time according to the grinding state of the products, the grinding head mechanism is high in grinding precision and efficiency, the grinding process is safe and reliable, meanwhile, an abrasive belt in the grinding head mechanism is convenient to disassemble and assemble, the abrasive belt is easy to operate, and the abrasive belt is high in utilization rate.
