specific Embodiment approach 3

[0027] Specific implementation mode three: combination figure 1 , Figure 4 and Figure 6 This embodiment is described. In this embodiment, both the pressing block 2-2 and the base 2-4 are disc-shaped and arranged coaxially. In this embodiment, the disc-shaped pressing block 2-2 corresponds to the shape of the pump casing 5-1, and such setting is more conducive to its close contact with the pump casing 5-1. The disc-shaped base 2-4 corresponds to the shape of the pump base 5-3, and such setting is more conducive to its close contact with the pump base 5-3. Other unmentioned structures and connections are the same as those in the first or second embodiment.

Abstract

The invention relates to a multidirectional positioning clamp and discloses a multidirectional positioning clamp for welding of a turbopump. The problem that gaps between all parts of a body part of an existing turbopump structure exist in the welding process to seriously affect the welding quality is solved. The multidirectional positioning clamp for welding of the turbopump comprises an L-shaped operation board, a vertical positioning assembly, a transverse positioning assembly and a nozzle positioning assembly, wherein the L-shaped operation board comprises a horizontal board and a vertical board which are perpendicularly arranged and are fixedly connected into a whole; the vertical positioning assembly and the transverse positioning assembly are arranged on the horizontal board; the transverse positioning assembly is located in front of the vertical positioning assembly; the nozzle positioning assembly is arranged on the vertical board; a mandrel is sleeved with a pump shell, a diversion outer shell and a pump base of the turbopump in sequence from top to bottom; a compression pressure block is tightly attached to the pump shell of the turbopump; a compression pressure sheet is fixedly connected to the end face, close to the mandrel, of a transverse positioning block and tightly attached to an air inlet flange of the turbopump. The multidirectional positioning clamp for welding of the turbopump is used for the welding process of the turbopump.

Description

technical field [0001] The invention relates to a multidirectional positioning fixture, which belongs to the field of mechanical processing. Background technique [0002] The structure of the turbo pump that needs to be welded mainly includes the pump casing, the guide casing, the pump base, the intake flange and the nozzle ring. According to the characteristics of the turbo pump structure, it is required to realize the integrated welding of the structure, the tight fit of the connected parts and the flushness of the connected end faces. During the welding process, there are gaps between the various components of the main part of the turbo pump structure, which seriously affects the welding quality. At present, there is no welding fixture for this type of pump structure with components such as flanges and nozzles. Contents of the invention [0003] In order to solve the problem that the welding quality is seriously affected by the existence of gaps between the various com...
