Embodiment 1

[0039]Working Principle of Embodiment 1: Firstly, the end of the fixture provided with the expansion screw 2 is vertically placed in the inverted conical workpiece, and then the installation rod 9 is inserted from the bottom to the bottom of the lower expansion core 61 inside the lower expansion sleeve 62 , then turn the installation rod 9, and tighten it with the threaded hole 8 at the bottom, and then make the lower expansion core 61 move down, because the lower expansion core 61 is tapered, and the lower expansion sleeve 62 is set as a three-lobed toothed structure, and cooperates with the lower expansion core 61. The arc surface of the core 61 realizes expansion, and then the expansion screw 2 is turned, the expansion screw 2 matches the thread inside the upper expansion core 41, and the setting of the gasket 3 prevents the expansion screw 2 from being connected to the upper expansion sleeve The friction force of 42 is too large, as the expansion screw 2 is tightened, the e...

Abstract

The invention relates to the technical field of machining, in particular to a clamp for fixing an inverted conical surface workpiece, which comprises an inverted conical surface workpiece, an expansion screw, a gasket, an upper expansion assembly, a connecting part and a lower expansion assembly, the upper expansion assembly is arranged above the connecting part, the lower expansion assembly is arranged at the other end of the connecting part, and the expansion screw is arranged on the lower expansion assembly. The upper expansion assembly and the lower expansion assembly are symmetrical, the gasket is arranged on the upper surface of the upper expansion assembly, and the expansion screw is arranged on the gasket. Through cooperation of the upper expansion assembly, the lower expansion assembly and the connecting assembly, threaded connection and extrusion of the mounting rod and the expansion screw, cooperation of the upper expansion sleeve and the upper expansion core or cooperation of the lower expansion sleeve and the lower expansion core, the upper end and the lower end of the device can be independently expanded, and in the spraying operation, paint spraying on the end face is sufficient and full; and secondary spraying operation is avoided, the working efficiency is indirectly improved, and the appearance of a product is greatly improved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a fixture for fixing an inverted conical workpiece. Background technique [0002] With the rapid development of machining spraying technology, the process of workpiece processing and spraying is getting higher and higher. In the prior art, the fixing methods for some workpieces with inverted conical surfaces are not ideal, and for some bottom sealing workpieces (such as Torch) processing, the inner wall of this kind of workpiece is relatively smooth, the general fixing device can not play a good fixing effect on these workpieces with relatively smooth inner wall, and cannot meet the current processing and spraying process for the conical surface of inverted conical workpieces need. [0003] 1. The existing technology is the upper and lower cones, which are fixed with bolts. Due to the shielding of the cones, the processing, spraying or other processing operations on the lower ...
