The invention discloses a drilling device convenient for fixing a workpiece, comprising: a support table; a first support plate, which is slidably arranged on the support table; and a transmission mechanism for driving the first support plate along the support table moving; a plurality of fixing mechanisms are arranged at intervals along the moving direction of the first support plate, wherein the fixing mechanism comprises: a second support plate, the second support plate is connected with the first support plate, and is provided with A plurality of first chutes, which are distributed at intervals along a circumferential direction; the workpiece is placed on the rotating plate and placed on the outside of the fixed rod, and the rotating plate is driven to rotate by rotating the first rotating shaft. The limit groove pushes the fixing rod and the slider to move outward, and squeezes the workpiece from the inside to fix the workpiece. The invention facilitates fast fixing of the annular workpiece. It is convenient to fix workpieces of different sizes, to ensure that the fixed center remains unchanged, and to facilitate subsequent drilling processing.
Description
technical field [0001] The invention relates to the technical field of workpiece drilling and processing equipment, in particular to a drilling device that is convenient for fixing workpieces. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill to machine holes in a workpiece. Usually the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes and blind holes, replace special tools, and can expand, countersink, ream or tap. [0003] In Chinese Patent Application No.: CN201711448451.1, a workpiece drilling device is disclosed, which includes a base, a drawer is installed in the inner cavity of the base, and the drawer includes a drawer frame and a drawer box. The sliders are matched with the sliding grooves inside the drawer frame. Support rods with the same structure ...
