Fixing device for ball workpiece machining

Abstract

The invention discloses a fixing device for ball workpiece machining. the fixing device for ball workpiece machining comprises a base, supporting seats are arranged at the two ends of the base in a sliding manner, arc-shaped clamping rings are movably arranged on the supporting seats, a supporting ring located between the two supporting seats is further arranged on the surfaces of the supporting seats, cavities are formed in the supporting seats, a sliding groove communicated with the cavities is formed on the upper end face of the base, a lead screw rod is rotatably arranged in each cavity, a right-hand thread structure is formed on a front section of each lead screw rod, a left-hand thread structure is formed on a rear section of each lead screw rod, lead screw nuts are fixed to the lower ends of the supporting seats, and the right-hand thread structures and the left-hand thread structures are sleeved with the two lead screw nuts correspondingly. The problems that when ball workpieces are machined, due to the particularity of the structures of the ball workpieces, the ball workpieces are extremely prone to sliding in the clamping process, the difficulty degree of subsequent machining is increased, the workpieces are extremely prone to being damaged, and the machining cost is increased are solved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing and fixing device for spherical workpieces. Background technique [0002] Fixture refers to the device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection. Fixtures are also called fixtures. In a broad sense, any process in the process that is used to install workpieces quickly, conveniently and safely can be called fixtures. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and position accuracy with other surfaces specified in the drawing, the workpiece must be installed an...
