Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] figure 1 It is a schematic diagram of the local structure of the clamping tool of the casing part provided by the embodiment of the present invention. The casing part A is in the shape of a circular table. Usually, when the tensioning type clamping tool is used to clamp this kind of casing part, only the casing can be processed. The outer circular surface of the part cannot be processed at the same time as the inner hole surface and the outer circular surface of the casing part. Therefore, the invention provides a clamping tool for the casing part, which can be clamped by a set of clamping tools to clamp the casing part at the same time. Process the inner and outer surfaces of casing parts.

The invention discloses a clamping tool for case parts. The clamping tool comprises a base used for holding the parts and a plurality of pressing plate assemblies used for pressing the case parts onto the base. Each pressing plate assembly comprises a main supporting rod, an auxiliary supporting rod, a pressing plate and a pressing nut, wherein the main supporting rod is sleeved with the pressing plate, and one end of the pressing plate is pressed on the auxiliary supporting rod. The pressing plate assemblies are mounted on the base and located in inner holes of the case parts or on the peripheries of the outer circles of the case parts. When the outer round faces of the case parts are machined, the small ends of the case parts are placed on the base, and the pressing plate assemblies are mounted on the base and located in the inner holes of the case parts so as to press the case parts; when inner hole faces of the case parts are machined, the big ends of the case parts are placed on the base, and the pressing plate assemblies are mounted on the base and located on the peripheries of the outer circles of the case parts so as to press the case parts; and accordingly, the inner hole faces and the outer round faces of the case parts are machined respectively.
Description
technical field [0001] The invention relates to the field of parts processing technology, in particular to a clamping tool for casing parts. Background technique [0002] The casings of medium and small gas turbines are usually cylindrical or frustoconical casings connected by multiple casing parts. Among the casing parts that make up the casing, there are a large number of conical casing parts. These casing parts are usually rolled from steel plates. During the process, the barrel wall of the casing parts is prone to deformation, making it difficult to manufacture. [0003] In the existing processing technology, the tensioning type clamping tool is usually used to clamp the casing parts. Specifically, the tension-type clamping tool is installed in the inner hole of the casing part. The tension-type clamping tool includes several tension blocks and drive units connected to the several tension blocks. The drive unit drives several The tension block moves in the inner hole ...
