The invention relates to the technical field of drilling machines, and discloses a clamping mechanism for a drilling machine. The clamping mechanism includes a base, support rods are fixedly installedat the four corners of the upper surface of the base, the upper ends of the four support rods are fixedly provided with a support plate jointly, a transverse cavity is arranged inside the support plate, the interior of the cavity is transversely provided with a two-way screw rod, the two ends of the two-way screw rod are rotatably connected to the two sides of the cavity through rolling bearings,and the right end penetrates to the outside of the support plate and is fixedly provided with a rocking handle; and the two sides of the rod wall of the two-way screw rod are provided with moving blocks in a threaded manner, the two moving blocks are in sliding connection with the cavity, the upper sides of the two moving blocks are fixedly provided with connecting blocks, the top of the cavity is symmetrically provided with two strip-shaped holes where the connecting blocks penetrate, and the upper sides of the two connecting blocks are fixedly provided with a first clamping plate and a second clamping plate. The clamping mechanism is high in clamping stability, the phenomenon that a valve stem is out of positions is avoided, and the drilling precision of the valve stem is improved.
Description
technical field [0001] The invention relates to the technical field of drilling machines, in particular to a clamping mechanism for drilling machines. Background technique [0002] During the processing of the ball valve stem, the formed blank needs to be processed in multiple ways. After the blank is cut, a valve stem with a head and a stem can be initially formed, and then the head of the valve stem needs to be milled. Then it is necessary to drill the end face of the head in order to install the steel ball at the drilled hole. [0003] At present, before the drilling process, the valve stem needs to be clamped and positioned, so the requirements for the fixture are relatively high. Generally, the mechanical clamping device will bear a large force when drilling, which is easy to cause deviation and affect the Drilling accuracy. For this reason, the present invention has designed a kind of drilling machine clamping mechanism. Contents of the invention [0004] The purp...
