Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing and relates to a gear honing machine top shape and position tolerance adjustment structure. Background Art

[0002] In the field of mechanical processing, powerful gear honing machines have become an indispensable key equipment in gear manufacturing due to their high efficiency and precise processing capabilities. As the basic component in mechanical transmission, the quality and performance of gears directly determine the operating accuracy and reliability of the entire mechanical system. Therefore, the processing accuracy and efficiency of powerful gear honing machines are of vital importance to improving the overall quality of gear products.

[0003] As one of the core components of a powerful gear honing machine, the centering mechanism is responsible for assisting the workpiece in processing and maintaining the rigidity of the workpiece system. During the gear honing process, the matching accuracy between the centering mechanism and the workpiece axis is directly related to the stability and accuracy of the processing. Ideally, the center axis of the centering mechanism and the workpiece axis should completely coincide to ensure that vibration and errors during processing are minimized, thereby obtaining high-quality gear products.

[0004] However, the top mechanisms in the prior art usually have problems such as complicated operation and low adjustment accuracy when adjusting parallelism and equal height. For example, some top mechanisms need to be disassembled and assembled repeatedly when adjusting parallelism, which is not only time-consuming and labor-intensive, but also difficult to ensure adjustment accuracy. At the same time, the equal height adjustment mechanisms in the prior art are often complex in structure, and errors are easily accumulated during the adjustment process, resulting in poor adjustment effects. Summary of the invention

The top shaft radial feed guide rail 260 is parallel to the workpiece shaft radial feed guide rail 130, and is mounted on the guide rail mounting seat 261. The guide rail mounting seat 261 includes a side plate 262 and a base 263. The top shaft radial feed guide rail 260 is mounted on the upper part of the side plate 262, and the lower part of the side plate 262 is movably connected to the base 263 through a plurality of mounting screws 264.

By adjusting the screwing depth of the first pull screw 233 and the first pressure screw 234 in the connecting ear 266, the side plate 262 is rotated around the first adjustment shaft 231 at a certain angle, thereby adjusting the horizontality of the side plate 262 to make it parallel to the workpiece shaft radial feed guide rail 130. Before adjustment, loosen the mounting screw 264 first, and tighten the mounting screw 264 after the top shaft radial feed guide rail 260 and the workpiece shaft radial feed guide rail 130 are completely parallel by adjusting the pressure screw 234 and the pull screw 233.

By adjusting the screwing depth of the second pull screw 243 and the second pressure screw 244 in the second connection block, the swivel seat 221 is rotated on the slide 223. Before adjustment, first loosen the connection screw 245, adjust the second pull screw 243 and the second pressure screw 244 to rotate the top shaft 220 in the radial feed plane, make the projections of the axis of the top shaft 220 and the axis of the workpiece axis 120 in the horizontal plane parallel to each other, and then tighten the connection screw 245.

[0055] Furthermore, two third adjustment shafts 246 are respectively inserted into the assembly seat 224 from opposite sides of the swivel seat 221 along the radial direction of the top shaft 220, and the assembly seat 224 is provided with a third adjustment hole 225 that matches the third adjustment shaft 246 with a micro-clearance, so that the assembly seat 224 can rotate along the third adjustment shaft 246.
