The milling cutter mechanism is provided on the lifting rod, so that the milling cutter mechanism The position can be set according to the stroke of the plate and the specific data to be processed, and at the same time, the height of the milling cutter can be adjusted according to the height of the plate; on the working table, there are also two slide rails on the inner side of the guide rail, and the slide rail is provided with a sheet Clamping mechanism, the sheet material clamping mechanism specifically includes a tractor and a cylinder clamping device. There are four cylinder clamping devices, two of which are a group, each group is set on a slide rail, and two groups of cylinder clamps The fixed connection between the tightening devices slides on the slide rail with the same motion trajectory. The cylinder clamping device is connected to the tractor through a connecting pipe. The tractor is specifically a cam trolley. A transmission chain is provided at the middle position of the worktable. The transmission chain A cam car is connected to the cam car, a gearbox and a motor are connected, the wheels of the car are set on the rails on both sides of the transmission chain, the center of the car is provided with a cam groove, the cam groove is provided with a cam, and the front side of the cam The tie rod is connected, and the head of the tie rod is bent downward to form a downward hook. The hook hooks down the transmission guide rail between the transmission chains. After the hook hooks the transmission guide rail, the carriage is driven forward by the transmission guide rail. When the cam moves backward The hook is lifted, and the rear side of the cam is provided with a clamping block for clamping the connecting pipe. The clamping block is clamped when the cam moves forward and relaxed when the cam moves backward, so that the hook at the front end of the cam carriage hooks the transmission guide rail , The clamping block clamps the connecting pipe, at this time the connecting pipe exerts a backward pulling force, and the drive rail applies a forward pulling force. The two forces form a balance. The trolley pulls the connecting pipe with the rotation of the drive chain and drives the four Cylinder clamping devices move forward together. The slide rail is provided with a station that restricts the forward movement of the cylinder clamping device. When the cylinder clamping device moves to this station, it stops moving forward and connects the pipe to the cam trolley When the backward pulling force is applied, the backward pulling force received by the cam trolley is greater than the forward pulling force. The backward movement of the cam causes the hook to lift and the trolley stops moving, so that each time the plate will be transported to a fixed station, greatly reducing The error caused by manual handling does not require proofreading its position before processing. After the plate is transported, the plate is clamped and the hook of the trolley is buckled into the transmission guide rail, saving time and effort. The cylinder clamping jaws of the cylinder clamping device It is also very flexible. The cylinder jaws can rotate on the cylinder at an angle, that is, the cylinder clamping device can clamp the plate in front and back, or left and right, and adjust flexibly according to the size of the plate.
