Description

Technical Field

[0001] The utility model relates to the technical field of horizontal honing machine clamping, in particular to a clamping tool for horizontal honing machine processing. Background Art

[0002] Honing machines are mainly used to hone the holes of workpieces in manufacturing industries such as automobiles, tractors, hydraulic parts, bearings, and aviation. In addition to honing machines for processing holes, there are also cylindrical honing machines, bearing raceway honing machines, flat honing machines, and curved surface honing machines for processing other surfaces. The honing machine needs to clamp the workpiece during operation to ensure the stability and accuracy of the workpiece during processing. Therefore, a clamping tool for horizontal honing machines is required.

[0003] The Chinese patent with patent announcement number CN217045943U discloses a horizontal honing machine, which uses a hydraulic device to adjust the height of the workpiece, and uses the cooperation of the honing assembly and the first drive device to complete the rotation processing inside the tool. The second drive device can easily adjust the position of the first drive device. The device is easy to use and has a simple structure. However, during the honing process, the first drive device will drive the honing assembly to rotate. Since the rod body of the main shaft is relatively long, it is easy to vibrate or shake during the rotation process. The honing position may be offset when contacting the workpiece, and the workpiece is placed on the pulley frame without being fixed. During honing, the workpiece will be offset. If the honing head is in close contact with the workpiece, it will also drive the workpiece to rotate. For this reason, a clamping tool for horizontal honing machine processing is proposed.
