Problems solved by technology

[0002] Double-journal blades usually need to perform datum conversion and positioning processing many times during the machining process of the journal. When the upper journal process section needs to be turned off, there are many problems in the interference of positioning points because the datum and the processing part are on the same side. As a result, the consistency of the parts after positioning and clamping is poor, it is difficult to meet the requirements of machining accuracy, and it is difficult to adapt to the requirements of mass production

Embodiment

[0028] Example: Select journal blades as needed, and the conversion sleeve (the X-direction positioning surface is designed for the conversion sleeve, the size of the inner hole and the journal are in clearance fit, and the conversion sleeve has three 0.5mm gaps, such as: figure 2 ), three gripping chucks. The blade is installed in the conversion sleeve, the blade reference A is in contact with the X-direction positioning surface of the conversion sleeve, the positioning surface A of the conversion sleeve is in contact with the end face of the three-grip chuck, and the conversion sleeve is subjected to force when the three-grip chuck clamps the reference surface B of the conversion sleeve. Elastic deformation, the three gaps of the adapter sleeve become smaller, and the blade journal is clamped.

Abstract

The invention provides a journal conversion clamping head for double-journal blades. The journal conversion clamping head comprises a limit plate and a clamping sleeve and is characterized in that thelimit plate is fixedly connected to one end of the clamping sleeve, a plurality of rotation holes are formed in the end face of the limit plate, a clamping hole is machined in the center of openings,and each rotation hole is connected with the clamping hole through one opening. The journal conversion clamping head has the advantages that simple and stable clamping positioning is achieved, X-direction alignment needed in each clamping is omitted, unqualified products caused by tool alignment errors and upper-journal length conversion errors are avoided, first time yield (the number of reworkparts is reduced greatly) and part yield are increased, machining labor intensity is lowered, and machining efficiency is increased.

Description

technical field [0001] The invention relates to a journal rotary chuck of a double journal type blade. Background technique [0002] In the process of journal processing, the double journal blade usually needs to perform datum conversion and positioning processing many times. When it needs to be turned off the journal process section, because the datum and the processing part are on the same side, there are many problems in the interference of positioning points. As a result, the consistency of the parts after positioning and clamping is poor, it is difficult to meet the requirements of machining accuracy, and it is difficult to adapt to the requirements of mass production. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned technical problems, the present invention provides a journal rotary chuck of a double journal type blade. [0004] The present invention is achieved through the following technical solutions. [0005] The present invention provide...
