Free gravity tempering support for artillery long pipe parts

Abstract

The invention discloses a free gravity tempering support for artillery long pipe parts, and belongs to the technical field of artillery part machining. The free gravity tempering support comprises a base, a guide rod, a guide sleeve, a cover plate, a floating sleeve, V-shaped iron and a belleville spring, the guide rod is fixedly connected to the center of the upper plane of the base in a threaded mode, and the guide rod is sleeved with the belleville spring in a clearance fit mode; the belleville spring penetrates through a concave circular ring groove in the lower part of the interior of the floating sleeve in a clearance fit manner, and the guide sleeve penetrates through an outer circular ring below the floating sleeve in a clearance fit manner; the annular-ring-shaped cover plate penetrates through a cylinder of the floating sleeve in a clearance fit manner, and the cover plate is fixedly connected with an outer circular ring at the top of the guide sleeve through a bolt; and a vertical screw rod is in threaded connection with the upper portion of the inner center of the floating sleeve, the V-shaped iron is connected to the top of the screw rod, a screw B is fixedly connected into the right side of the floating sleeve, the front end of the screw B abuts against a key groove of the screw rod, and a nut is fixedly connected to the top of the floating sleeve. According to the free gravity tempering support for the artillery long pipe parts, the deformation influence of gravity on workpieces when long pipe and long shaft parts are tempered by adopting a table type furnace is reduced.

Description

technical field [0001] The invention relates to a free gravity tempering support for artillery long-tube parts, belonging to the technical field of artillery parts processing. Background technique [0002] When a long tube part of an artillery needs to be tempered, because a desktop tempering furnace is used, the workpiece must be placed horizontally during the tempering process, the gravity direction of the workpiece is perpendicular to the axis, and the tempering and holding time of the workpiece is long. During the process, the workpiece will be deformed to a certain extent in the direction of gravity. The existing solution is to set two support points in the middle of the workpiece. When loading the furnace, the operator puts the pad iron under the support point and uses a wedge-shaped iron block to tighten it. The disadvantage of this method is that the support force is completely determined by the operator. It is controlled by work experience and cannot be quantified....

Problems solved by technology

The existing solution is to set two support points in the middle of the workpiece. When loading the furnace, the operator puts the pad iron under the support points and tightens it with wedge-shaped iron blocks. The disadvantage of this method is that the support force is completely determined by the operator. It is controlled by work experience and cannot be quantified. When the support force is small, the influence of gravity still exists; if the support force is too large, a force opposite to the direction of gravity will be generated, which will still affect the deformation of the workpiece
