Automatic fixture of rotary cylinder front-mounted grinding machine

Abstract

The invention relates to an automatic fixture of a rotary cylinder front-mounted grinding machine, comprising a fixture, and further comprising a rotary cylinder and a spring device applying radial inward force to clamping members. The fixture comprises a connecting disc, and a plurality of clamping members arranged on the front side face of the connecting disc and connected with the connecting disc in a radial sliding manner; the rotary cylinder is arranged in the axial direction; the front portion of a piston body is conical and extends out of the front end of a cylinder block of the rotarycylinder; a plurality of radial transmission members are arranged on the rear side face of the connecting disc, the radial inner sides of the radial transmission members can make pressure contact withthe conical surface of the front portion of the piston body; the radial transmission members are movably connected with the connecting disc in the radial direction; the radial transmission members and the clamping members are in one-to-one correspondence, and adopt the same circumferential distribution manner as that of the clamping members; and the radial outer ends of the radial transmission members are in radial transmission connection with the corresponding clamping members, respectively. The fixture is simple in structure, and implements automatic clamping of parts on the premise that the main structure of a grinding machine headstock is not changed.

Description

technical field [0001] The invention relates to an automatic jig for a rotary cylinder front grinder. Background technique [0002] At present, the head frames of most grinding machines do not have the function of automatic workpiece clamping. For example, the common connecting disc fixture is composed of a connecting disc body, movable jaws and jaw driving mechanism. There are threads and discs under the jaw guiding part. The flat threads on the back of the bevel gear mesh with each other. When the small bevel gear is rotated through the square hole with a wrench, the disc gear rotates, and the flat threads on the back drive the claws to approach or withdraw from the center at the same time to clamp workpieces with different diameters. , these manual operations often consume more time. [0003] With the development of automation technology and the increase of labor costs, the need to reduce the number of machine operators and realize the automatic processing of parts is be...
