Special double-station double-groove milling and hole drilling clamping device

Abstract

The invention relates to a special double-station double-groove milling and hole drilling clamping device which comprises a working platform, a central column and positioning devices. The vertical central column is mounted in the middle of the upper surface of the working platform, and the two positioning devices are mounted on the working platform and are respectively symmetrically arranged on the left side and the right side of the central column; each positioning device comprises an upper adjusting pressure plate, a lateral positioning block and a movable ejector rod, each upper adjusting pressure plate is used for positioning a workpiece, and a workpiece positioning zone is formed among each upper adjusting pressure plate, the corresponding lateral positioning block, the corresponding movable ejector rod and the central column. The special double-station double-groove milling and hole drilling clamping device has the advantages that the special double-station double-groove milling and hole drilling clamping device is scientific in design, reasonable in structure and long in service life, the production cost can be reduced for an enterprise, groove milling and hole drilling machining can be performed on two workpieces after the two workpieces are clamped by the special double-station double-groove milling and hole drilling clamping device at one step, accordingly, the work efficiency can be improved by three times, and requirements on the precision of various dimensions of the machined workpieces can be met.

Description

technical field [0001] The invention relates to the field of positioning and clamping devices, in particular to a special clamping device for double-station milling and double-slot drilling. Background technique [0002] The lower surface of the side cover of the sewing machine needs to be milled and drilled. At present, milling and drilling are two processes, and only one process can be performed at a time. Therefore, two clampings are required to complete the two processes. The clamping time is long, the production efficiency is low, and repeated clamping also affects the machining accuracy. In addition, since only one part can be processed at a time, the processing speed is also slow and the efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a special clamping device for double-station milling and double-slot drilling with fast processing speed, high efficiency and high precision. [0004] The purpose of the present...
