Embodiment Construction
[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0033] see figure 1 , 2 and 3, a straightener 10 for keyway machining, consisting of a round shank 11 and a measuring part 12.
[0034] The diameter of the round tail shank 11 is the same as that of the milling cutter afterbody, and is all matched with the milling cutter chuck. In the present invention, the diameter of the round tail handle 11 is Φ20 and the height is 40mm.
[0035] The measuring part 12 is located below the round handle 11, and the measuring part 12 and the round handle 11 can be molded integrally or connected together by welding. The measuring part 12 is provided with a "∧" jaw 121 which can be used to accommodate the workpiece to be processed, and the "∧" jaw 121 is symmetrical about the axis 111 of the round tail handle 1...

The invention relates to an alignment device for keyway processing, comprising a round tail handle which is matched with a milling cutter chuck and a measurement part arranged below the round tail handle, wherein the measurement part is provided with an inverted V-shaped nip which can contain a processed part, and the inverted V-shaped nip is symmetric according to an axial line of the round tail handle. A using method of the alignment device for keyway processing comprises the following steps of, firstly, clamping the round tail handle of the alignment device for keyway processing on the milling cutter chuck of a milling machine; secondly, moving the alignment device for keyway processing or the processed part so that the processed part is located in the inverted V-shaped nip of the alignment device for keyway processing, and enabling both clamping edges of the alignment device for keyway processing to be contacted with an excircle of the processed part, or enabling gaps between the processed part and both clamping edges of the inverted V-shaped nip to be equal; and thirdly, replacing the alignment device with a milling cutter. The invention has the advantages of overcoming the disadvantages of low cutting way accuracy and slow speed through visual incision measurement, lowering the technical requirement on an operator and enhancing the labor productivity.
Description
technical field [0001] The invention relates to a part for milling machine to process key grooves and a using method thereof, which can ensure fast and accurate tool setting when milling cutters are used to process key grooves. Background technique [0002] In the machinery manufacturing industry, milling machines are often used to process keyways on shaft parts. But in keyway processing, there is a problem of how to set the tool. That is, align the keyway milling cutter with the axis of the shaft to ensure that the machined keyway meets the symmetry required by the design. Since the symmetry of the keyway is a necessary condition to ensure smooth assembly, its processing quality directly affects the performance and service life of the entire device, so every effort is made to align the axis of the keyway milling cutter and the shaft during processing to meet the design of the part Require. [0003] Nowadays, the cutting mark visual inspection method is generally used for...
