Problems solved by technology
During molding, the friction between the mold and the table can balance the horizontal thrust. This method is still effective, but as the blade becomes larger, the horizontal thrust generated by forming will increase exponentially. If the traditional table locking device is used, it cannot With such a large horizontal thrust, there is a danger of table slippage

A positioning and locking device of a movable working table is applied to the technical field of hydraulic machines and comprises transverse positioning blocks, an end positioning block, movable positioning devices and a base plate. The two transverse positioning blocks, the end positioning block and the two movable positioning devices are fixed to a lower cross beam A through bolts, and the lower portion of the end positioning block protrudes to be embedded into the lower cross beam A; the base plate is fixed to the end positioning block through a bolt; and each movable positioning device is composed of a support, a lug base bottom plate, a hydraulic cylinder, a proximity switch, a lug base, a guide sleeve, a locking pin, a lining plate and a sliding plate. Pistons of the hydraulic cylinders are connected with the locking pins through the lug bases, and the locking pins slide in the guide sleeves; and cylinder bodies of the hydraulic cylinders are connected with the lug base bottom plates through the lug bases. When a hydraulic machine carries out compressing, peripheral locking blocks can resist horizontal pushing force in any direction, and risks of slipping of the working table can be completely avoided. The positioning and locking device of the movable working table is simple in structure, convenient to use and convenient to maintain and adjust, and can resist horizontal force.
Description
technical field [0001] The invention relates to a positioning and locking device for a mobile workbench of a hydraulic machine resisting horizontal thrust in the technical field of hydraulic machinery. Background technique [0002] At present, the hydraulic press is usually composed of an upper beam, a movable beam, a column, and a lower beam. This special hydraulic press is used for hot molding of large blades. Since the blade itself is a complex space distortion body, it will generate a large horizontal thrust during the hot forming process. This thrust will be transmitted to the movable beam and mobile worktable through the mold. There are guides between the beams and columns that resist this force. This force is transmitted to the mobile table, and the friction between the mobile table and the base during molding is not enough to balance the force. If the mobile table does not have a corresponding locking device, the mobile table will slip. In a dangerous state, not on...
