[0011] Working principle: First, place the UB110 bushing to be tapped between two brackets, and the two brackets support the bottom of the bushing. At this time, turn on the industrial camera, and the linear motion module controls the industrial camera to move to the top of the bushing. The industrial camera will detect the mark point mark below through the hole in the middle of the bushing. When the mark point mark is blocked, the first motor is started, and the first motor will drive the transmission shaft to rotate. Through the reduction transmission of the two worm gear reducers, the first transmission wheel and the second transmission wheel are driven to rotate, thereby driving the two synchronous belts to perform motion transmission. The inner end of the synchronous belt is tightly attached to the outer wall of the bushing.

At the center, the second motor drives the bidirectional threaded rod to rotate, and through the limit of the guide rod, it will drive the two clamps to move inward at the same time, thereby clamping the bushing and improving the stability during subsequent processing. Then the linear motion module controls the tap to move above the central hole of the bushing and starts the third motor. The spindle of the third motor drives the tap to rotate after being driven by the coupling and decelerated by the reducer. At this time, the electric cylinder starts, and the driving end of the electric cylinder pushes down the bump, which drives the fixed plate to move downward, thereby driving the tap to move downward to realize the tapping operation of the bushing. During this period, the pump is turned on, and the pump pumps out the coolant in the coolant storage tank and sprays it out through the output pipe and nozzle to cool the operation process. The debris generated during the operation will be intercepted by the filter, and the coolant will return to the coolant storage tank for the next use.

[0012] The present invention provides an automatic tapping device for UB110 bushing processing, which has the following beneficial effects: 1.
