Press fit tool

Abstract

The invention discloses a press fit tool. The press fit tool comprises air cylinders, a controller, a detecting device and a timer, the controller is used for controlling the air cylinders to extend and retract to enable the air cylinder to be press fit with a workpiece or be separated from the workpiece, the detecting device is used for detecting the input air pressure of the air cylinders, and the timer is used for timing the time of the air cylinders performing press fit on the workpiece. The timer can be connected with the controller and the detecting device in a communication mode, and when the timing time of the timer achieves a preset time, the controller controls the air cylinders to be separated from the working piece; and when the input air pressure of the air cylindersdetected by the detecting device is smaller than a preset pressure value, the timer stops timing, and when the input air pressure of the air cylinders detected by the detecting device is larger than or equal tothe preset pressure value, the timer keeps timing. Through the arrangement, the condition that during the press fit process of the air cylinders and the workpiece, the pressure applied to the workpiece and the applied time meet the technology requirements constantly is ensured, the quality of the workpiece is ensured, and the problem existing in the prior art that when the air cylinders perform press fit with the workpiece, the air pressure fluctuation has influence on the quality of the workpiece is solved.

Description

technical field [0001] The invention relates to the technical field of tooling equipment, more specifically, to a pressing tooling. Background technique [0002] For the workpiece after sticking 3M glue or brushing the adhesive, generally use the pressing tool to carry out the pressing operation. The pressing tool realizes the pressing operation of the workpiece through the expansion and contraction of the cylinder. Among them, the pressure and action time acting on the workpiece are important process parameters that affect the quality of the workpiece. In the existing pressing tooling, when the cylinder is inflated, it stretches and presses with the workpiece. At this time, the timer starts counting; However, when the cylinder is pressed against the workpiece, the input air pressure in the cylinder will drop due to the impact of the cylinder inflation, resulting in a decrease in the pressure acting on the workpiece, and the timer is still counting at this time. Therefore,...
