Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0018] Such as figure 1 As shown, a method of using a planer to process a long shaft keyway, it includes the following steps:
[0019] Step 1: Select a planer with an appropriate stroke according to the length of the long-axis workpiece 1 to be processed with the long-axis through the keyway, use two clamps 2 to clamp the long-axis workpiece 1 to be processed, and adjust the straightness and pre-tightening force between the clamps 2 , clamp the two ends of the long-axis workpiece 1 to be processed with the fixture 2, determine the clamping height of the long-axis workpiece 1 to be processed, place a support block 3 under the long-axis workpiece 1 to be processed, and place the long-axis workpiece 1 to be processed 1 fixed firmly;
[0020] Step 2, according to the size of the keyway to be processed, select and install a tool 5 of appropriate specifications; ...

The invention relates to the technical field of machining and discloses a method for machining a through keyway of a long shaft by utilizing a planer. The method comprises the following steps: selecting the suitable planer, clamping both ends of a long shaft workpiece to be machined by two fixtures, determining a clamping height of the long shaft workpiece to be machined, placing a plurality of supporting blocks below the long shaft workpiece to be machined and firmly fixing the long shaft workpiece to be machined; selecting and installing a tool with a suitable specification; firstly, carrying out rough planing machining, then replacing the tool with a forming tool to carry out forming machining on the through keyway, and finally, carrying out precise planing operation to obtain the through keyway with a regular size. According to the method disclosed by the invention, straightness and the degree of symmetry of the through keyway and firmness of clamping are convenient to ensure; the phenomenon of tool vibration in the planing process can be eliminated and machining equipment is improved; roughness of the machined face the through keyway can be effectively ensured so as to accord with the requirement on machining accuracy; the clamping times of the workpiece are small, the machining accuracy is high, production efficiency is effectively improved and production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for processing long shaft through key grooves by using a planer. Background technique [0002] In the process of mechanical processing, the processing of key grooves is generally carried out on machine tools such as milling machines, slotting machines, broaching machines, etc., which can meet the processing of key grooves of most mechanical parts. When processing the keyway on the long axis with a length greater than 1.5 meters, the above machine tools cannot guarantee the symmetry, straightness, tolerance and other dimensions of the keyway. The precision of the machined keyway is not enough, and the quality of the workpiece cannot meet the requirements. The workpiece is scrapped, resulting in a waste of materials. Contents of the invention [0003] The object of the present invention is to provide a method for machining long shaft through key grooves wi...
