Through production practice, we overlap the two halves of the gears one at a time, without having to consider the accuracy of the boring machine. As long as the boring spindle is used to machine the upper and lower positioning pin holes corresponding to the two half gears, the coordinates of the left and right axes of the spindle are fixed. This controls the coordinate error in one direction (horizontal direction), while the coordinates in the other direction can be precisely controlled by measuring the height. This makes it possible to machine the required holes with lower precision equipment.
The processing principle is as shown.
The main processing techniques are as follows: (1) After the first annealing, the split surface is rough-processed on a planer (or similar machine tool) by scribing.
(2) Drill the two half gear bolt holes on the drill bed according to the scribe line; use bolts to join the two halves of the blank.
(3) Use the vertical car to press the inner, outer and end faces of the car.
(4) In order to reduce the deformation error, after roughing, stress relief must be performed, and the second artificial aging (annealing) treatment.
(5) Then correct the two half gears as shown in the figure, and uniformly weld the two half gears together in an outer circle and an inner hole.
(6) Use the planer to position the A and B faces and the C and D faces at a time, so that the C face (the reference plane for measuring the height direction) has a perpendicularity to the AB face of 0.05 mm or less.
(7) Finally, the workpiece is mounted on the working table of the moving boring machine and the boring and milling machine. The workpiece is supported by the jack or the adjustable slanting iron, and the AB surface is adjusted to be perpendicular to the main axis. The tolerance is 0.0050.008mm; and the C surface is measured by the dial gauge. , tolerance 0.005mm in length L. Then fasten on the workbench.
After the AB and C faces meet the requirements, you can start to drill the locating pin holes. Pay attention to the order of the pupils when boring. That is, the holes A1, A2, A3, A4 (or from B1, B2, B3, B4) in the vertical direction are first slid, and then the spindle distance L is moved horizontally and then B4, B3, B2, B1 holes are sequentially moved. .
The holes in the same vertical position are placed in a coaxial position so that the size L tolerances of the pin holes on the two half gears are exactly the same. Because the spindle only moves up and down at this time, the left and right direction is fixed. This guarantees the coordinate accuracy of one direction. The coordinates of the other direction, that is, the distance of the up and down movement, can be controlled by placing a height gauge with a dial gauge on the C surface, measuring the highest point of the spindle, and recording the l1 of the 镗A1, A2, A3, and A4 holes. The actual size value of l2, l. After the A4 hole is finished, keep the spindle height coordinate unchanged, and shift the spindle to L to reach the position of the B4 hole. In order to eliminate the error of the C-face, the height dimension and the dial gauge should be used to re-calibrate the actual size of the C-plane to the highest point of the outer diameter of the spindle, and the dial gauge is set to the zero position as the measurement B3, B2, B1. The reference point of the hole. Do not move the dial gauge at this time. After the B4 hole is finished, the left and right positions of the spindle cannot be moved, and the spindle is only moved upward by a distance (note that it must be the same as the size error of the 销A3, the positioning pin hole of the machining principle A4 hole) 镗B3 hole, according to this method Until the end of B2, B1 hole. If the height and dimensional accuracy is not high, it is best to use a special cylindrical block gauge (that is, a cylindrical rod with tolerances on both ends) for comparative measurement to ensure the accuracy of l1, l2, l3; another method is to accurately measure with calipers The distance between the two holes, the boring machine diagram of the assembly of the vertical column and the power head is consistent with the corresponding hole distance (at this time, the influence of the aperture error must be paid attention to), of course, this method is affected by the level of pupil measurement. In addition, if the C-plane is difficult to use as a measurement reference, a high-precision standard square ruler can be fixed at two places on the table at a distance of L as a reference for comparison measurement, or two small angle irons with a verticality of 0.010 mm are specially made. The original screw hole on the AB surface is fastened on the bisector as a measurement reference. In short, regardless of the measurement method used, the position error of the vertical hole can be accurately controlled.
Locating the pin hole with a self-made boring machine If there is no spindle-moving boring and milling machine, it is also possible to assemble two soil boring machines with a column and a power head, respectively placed at two positions apart from each other. At this time, the positioning accuracy is all converted into a high measurement problem. When assembling, the rail surface and the C surface of the column should be horizontal and horizontal with a level (accuracy 0.010/1000). The perpendicularity of the main axis and the split surface (ie, the AB surface) can be found perpendicular to the dial gauge as shown. That is, the magnetic watch stand and the dial gauge are fixed on the main shaft, and the radius of the position where the dial gauge head is adjusted is equal to twice the tooth width. Then, when the main shaft is rotated by hand for one week, the column is adjusted so that the maximum reading of the dial gauge on the main shaft is not greater than 0.005mm. At this time, the parallelism of the two columns is also basically adjusted at the same time. The measurement and control in the vertical direction are basically the same as described above.
For the processing of other similar holes, the same method can be used as the processing of the positioning pin holes.
