Pneumatic clamping device with elevating function

Abstract

The invention discloses a pneumatic clamping device with an elevating function. The device comprises a cylinder, a mounting board, mounting seats and an elevating rod. The cylinder is a double-actingcylinder. Additionally, the lower end of a piston rod is fixed on a crossbeam. A perforating hole allowing the elevating rod to move up and down is arranged in the piston rod of the cylinder. The lower end of the elevating rod penetrates through the crossbeam to be connected with a cut head. The upper end of the cylinder is equipped with the mounting board. The middle of the mounting board is provided with a through hole allowing the elevating rod to pass through. The two groups of mounting seats are symmetrically installed outside the upper end of the mounting board. Clamp blocks capable of turning over towards the inside are hinged onto the mounting seat through hinged shafts. The clamping movement of the elevating rod is achieved. Then, the elevating rod is drive to ascend at fixed height such that the cut head can move upward for certain distance after cloth material is pressed. Accordingly, a fixed-length gap exists between the cut head and cloth material. The cloth material is prevented from wrinkling or turning over during movement so that garment quality is improved.

Description

technical field [0001] The invention relates to the technical field of cutting beds, in particular to a pneumatic clamping device with lifting function. Background technique [0002] Automatic cutting bed mainly includes cutting table, beam, cutting head, vacuum suction device and control system, etc. The crossbeam is erected on the cutting table, driven by the transmission shaft to move in the x-axis direction of the tabletop, the cutting head is installed on the crossbeam, driven by the transmission shaft to move in the y-axis direction of the tabletop, the cutting head is equipped with a cutter, crossbeam and cutting The heads jointly drive the cutter to complete various curves or straight lines on the table. The control system controls the cutting position, shape and route, cutting speed, cutting tool conversion, grinding distance, beam and cutting head start, temporary and termination cutting and other processes. When cutting, the fabric needs to be laid flat on the c...
