Floating equal-height pad assembly for vertical drilling machine

Abstract

The invention discloses a floating equal-height assembly for a vertical drilling machine. The floating equal-height pad assembly comprises an equal-height pad (1), a floating block (2) and a countersunk head screw (3), wherein the bottom part of the equal-height pad is provided with an installing base (1a), a positioning hole (1e) is formed in the bottom part of the installing base, an arc groove (1b) of which the front part and the rear part are communicated in a penetrating way is formed in the top part of the equal-height pad, and a blind threaded hole (1c) which stretches downwards is formed in the middle part of the arc groove; the floating block is a crescent-shaped elongated block which is matched with the arc groove and is exactly arranged in the arc groove, a countersunk head slotted hole (2a) which corresponds to the blind threaded hole in position is formed in the middle part of the top surface of the crescent-shaped elongated block, and workpiece supporting surfaces (2b) are formed as the left side and the right side of the top surface of the crescent-shaped elongated block respectively stretch upwards; the rod part of the countersunk head screw stretches into the blind threaded hole after penetrating through the countersunk head slotted hole, and thus the equal-height pad is connected with the floating block. According to the floating equal-height pad assembly for the vertical drilling machine, disclosed by the invention, the floating equal-height pad assembly is specially used for supporting a workpiece of which the bottom surface is rough and can be used for reliably positioning the workpiece by being combined with a pressing block, and the workpiece is prevented from swinging during a drilling process.

Description

Technical field [0001] The invention relates to a floating contour pad assembly for supporting a workpiece on a vertical drilling machine, which belongs to an auxiliary structure of production equipment. Background technique [0002] Vertical drilling machines are used to drill workpieces. Usually, the workpiece is placed on a fixed support block of the vertical drilling machine table, and then the pressure block is combined to compress the workpiece. Finally, the drill bit of the vertical drilling machine is used to drill the workpiece. For the workpiece with a flat bottom surface, it can ensure that the workpiece is in good contact with the fixed support block, and then the pressure block is combined to compress the workpiece; however, for the workpiece with a rough bottom surface, the fixed support block and the pressure block cannot reliably compress the workpiece. The workpiece may swing during the drilling process, causing drilling errors. Summary of the invention [0003] ...
