Description

Self-centering tool fixture for metal processing Technical Field The utility model belongs to the technical field of tool clamps, and particularly relates to a self-centering tool clamp for metal processing. Background In machining, some precision casting semi-finished products do not need clamping due to the size change of the precision casting semi-finished products, positioning is inaccurate, and the position to be machined of the precision casting semi-finished products needs high precision, so that a positioning fixture is needed to position and clamp the workpiece of the precision casting semi-finished products to be machined. The existing fixture is complex in structure or troublesome in unloading, and in most cases, self-centering cannot be achieved, machining requirements of a precision casting semi-finished product cannot be met, and machining precision of the precision casting semi-finished product workpiece is poor. Based on the above, a novel self-centering tool fixture for metal processing needs to be provided. Disclosure of utility model The utility model mainly aims to provide a self-centering tool clamp for metal processing, aiming at the defects of the prior art. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a metal processing is with from centering frock clamp, is in including anchor clamps seat and setting anchor clamps subassembly on the anchor clamps seat, the anchor clamps subassembly includes first anchor clamps subassembly and second anchor clamps subassembly, first anchor clamps subassembly is established the bottom of anchor clamps seat, the second anchor clamps subassembly is established the anchor clamps seat surface, first anchor clamps subassembly is including the circumference setting first jack catch, second jack catch and the third jack catch of anchor clamps seat bottom, first jack catch second jack catch with the third jack catch is used for being connected with lathe chuck cooperation in order to realize that frock clamp rotates along lathe chuck from the centering, the second anchor clamps subassembly includes boss, a plurality of pin and a plurality of reference column, the boss is established the central point department of anchor clamps seat, pin with reference column Zhou Xiangshe is in turn anchor clamps seat surface edge position. Preferably, the pin has the same height relative to the clamp seat surface as the positioning column. Preferably, the fixture seat surface is fixedly provided with a plurality of limit posts, and the limit posts are circumferentially distributed on the periphery of the boss. Preferably, the height of the limiting post relative to the surface of the clamp seat is smaller than the height of the boss. Preferably, the pin and the positioning column are both welded on the surface of the fixture seat.
