The invention discloses a vertical-positioning perforating device used for
machining and belongs to the technical field of mechanical part
machining. The problem that clamping positioning is difficultwhen the outline dimension or performance of a workpiece is changed is solved. The technical scheme includes that the perforating device comprises a
workbench, a supporting frame, an upper positioning plate, a lower positioning plate, a
noise-reduction box and a perforating
drill bit; a damping base is mounted at the bottom of the
workbench; the supporting frame is mounted on the
workbench; the top of the supporting frame is connected with the
noise-reduction box; a sliding block is arranged in a vertical sliding groove in a sliding mode; the top of the sliding block is connected with a hydraulic block through a hydraulic rod; the bottom of the sliding block is connected with the upper positioning plate through a jacking pressure rod; the lower positioning plate is arranged under the upper positioning plate; and the
hydraulic cylinder drives the sliding block to move, so that the upper positioning plate is driven to move, the upper positioning plate is matched with the lower positioning plate, the workpiece is clamped by means of clamping blocks and clamping rods, the perforating device is applicable to clamping and fixing of workpieces in different shapes, perforating operation on the workpiece is achieved through the perforating
drill bit, operation is convenient and fast, and the perforating precision is high.
