Description

Ejector rod clamp holder for numerical control machining Technical Field The utility model relates to the field of machining, in particular to a push rod clamp holder for numerical control machining. Background When the ejector rod is processed in a numerical control mode, the traditional clamping method is to clamp the ejector rod by utilizing a mode that the equal-height cushion blocks and the flat tongs are overlapped and used together, and the clamping is carried out by matching with the pressing plate, because the lengths of the ejector rods are different, the heights of the equal-height cushion blocks are required to be frequently adjusted, and the flat tongs are required to be straightened and corrected once every time the height is adjusted, and occasionally, the overlapping errors are too large and out of tolerance, the flat tongs are required to be assembled again, and the auxiliary time is wasted again. The processing efficiency is severely reduced. Disclosure of utility model In view of the above problems, the present utility model aims to provide a mandrel holder for numerical control machining, which is used for realizing rapid clamping and positioning of mandrel with different specifications, so as to overcome the defects of the prior art. The utility model provides an ejector rod clamp holder for numerical control machining, which comprises a base and a clamping mechanism fixedly connected to the base and used for fixing the position of an ejector rod close to the head, wherein an installation cavity is arranged in the base, a V-shaped guide opening is arranged at the top of the installation cavity and used for enabling the bottom of the ejector rod to smoothly fall into the installation cavity, and an adjusting cushion block used for supporting the bottom of the ejector rod is arranged in the installation cavity. The clamping mechanism is used for clamping the ejector rod with the round head, and comprises a clamping handle (a handle), a spring clamping sleeve (ER clamping head) arranged on the clamping handle and a fastening nut sleeved on the spring clamping sleeve, wherein the bottom of the clamping handle is fixedly connected to the upper end of the base through a bolt, a through hole in the clamping handle corresponds to the position of a V-shaped guide opening at the upper end of the installation cavity, the top of the clamping handle is fixedly connected with the spring clamping sleeve, the head of the ejector rod is placed into a clamping hole of the spring clamping sleeve and is clamped in the clamping hole of the spring clamping sleeve by the fastening nut, and the ejector rod after being clamped and fixed is automatically centered in numerical control machining.
