Problems solved by technology
[0002] In the existing blade processing technology, the problem of blade deformation has not been effectively solved
The processing of the blade process standard is strictly separated from the processing process of the blade body, and the blade body is a complex curved thin-walled structure, deformation will occur in the rough machining, semi-finishing and finishing processes, and the error of the blade body relative to the process standard will gradually accumulate increase, seriously affecting the final accuracy of the blade
[0003] The existing blade process benchmark correction step is generally placed after the finishing of the blade body is completed, and cannot fully compensate for the deformation of the blade body
[0004] The existing devices for blade reference processing and correction mostly use low-melting point alloy box-type tooling, which is cumbersome, polluting, and poor in repeatability

Embodiment Construction
[0033] The technical solution of the invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0034] The present invention is a device for datum correction of biaxial micro-deformed blades, which is composed of a blade body positioning device and a datum self-adaptive locking device. Press tight.
[0035] The invention relates to a device for modifying the datum of a biaxial slightly deformed blade, which is installed on a three-jaw chuck of a lathe or an outer cylindrical grinder through the outer circle of a base to correct the datum axes at both ends of the biaxial blade. The device is composed of a blade body positioning device and a reference self-adaptive locking device, and the blade body positioning device and the reference self-adaptive locking devices at both ends are fixedly connected by two connecting screws 13 respectively. The blade body positioning base 2 is provided with an X-direction positioning block 4, a Z-...

A device for correcting a double-shaft micro-deformation blade reference comprises a blade body positioning device and a reference adaptive locking device which are connected by connecting screws and compressed by disc springs in advance. An X-direction positioning block and five height-adjustable positioning dowels are arranged in the blade body positioning device according to a six-point positioning principle, the blade positioning device is provided with set screws, elastic compressing devices are arranged in the blade body positioning device along a Y direction and a Z direction, and the reference adaptive locking device consists of reference locking blocks, flexible spherical sleeves and locking screws. By the aid of the device, the position of a body of a blade relative to the axis of a reference of the device can be adjusted, allowance uniformization of a semi-finished blade and final deformation uniformization of a finely finished blade are realized, accordingly, original technological reference of the blade is corrected by the body used as a reference, and final processing precision of the blade is improved. In addition, the device has a good practical value and a broad application prospect in the field of special blade processing fixtures.
Description
technical field [0001] The invention relates to a device for datum correction of biaxial micro-deformed blades, which can correct the original process datum of deformed blades by blade body positioning. The utility model belongs to the technical field of special fixtures for processing blades. Background technique [0002] In the existing blade processing technology, the problem of blade deformation has not been effectively solved. The processing of the blade process standard is strictly separated from the process of the blade body, and the blade body is a complex curved surface thin-walled structure, deformation will occur in the rough machining, semi-finishing and finishing processes, and the error of the blade body relative to the process standard will gradually accumulate The increase seriously affects the final precision of the blade. [0003] The existing blade process standard correction step is generally placed after the finishing of the blade body is completed, an...
