Embodiment

[0029] like Figure 1-5 As shown, the main frame 3 is installed on the base 4, the overturned inner tube 2 is installed in the main frame 3, and the workpiece turbine cover is fixed on the overturned inner tube 2, and the overturned inner tube and the workpiece are respectively axially positioned, end-face positioned and angularly positioned; Axial positioning, end face positioning and angular positioning are respectively performed on the flip inner tube and the main frame described above. .

[0030] The overturned inner tube and the workpiece are axially positioned through the inner hole; the inner end face of the overturned inner tube is clamped with the end face of the workpiece for end face positioning; the workpiece is provided with an angular positioning hole; the overturned inner tube and the workpiece pass through the corner Angular orientation to the pilot hole.

[0031] The overturned inner tube and the main frame end face are clamped for end face positioning, and ...

Abstract

The invention relates to a turning clamp. The structure is that a main framework is mounted on the base; a turning inner tube is mounted in the main framework; a workpiece is fixed on the turning inner tube; the turning inner tube and the workpiece are respectively subjected to axial positioning, end face positioning and angular direction positioning; the turning inner tube and the main framework are respectively subjected to axial positioning, end face positioning and angular direction positioning. The turning clamp is a tool for processing a butt-joint molded surface of a worm wheel cover, so that requirements on the coaxiality, the size and the angular direction position of the molded surface butted to the worm wheel cover are guaranteed; the turning clamp is convenient to dismount and mount, high in practicability and high in processing efficiency.

Description

technical field [0001] The invention relates to a jig tooling, in particular to a flipping jig, which is suitable for surface processing technology in which front and back sides are joined together. Background technique [0002] The material of the turbine cover is GH4141, which is a high-temperature alloy material. The material is hard and difficult to process. The angle, size tolerance and technical requirements are extremely strict. A little carelessness in the process of processing will result in waste products. The turbine cover is a key part of the turbo pump, and the processing of the throat diameter is also the key to the processing of the turbine cover. If there is any error in the angle and coaxiality of the docking profile, the flow will change, which will affect the normal operation of the turbo pump. Because the profiles at both ends of the throat diameter cannot be processed in place at one time, a second clamping is required. Due to the small throat diameter, ...
