Description

Technical Field

[0001] The utility model belongs to the field of mechanical parts processing, in particular to a clamping tool for processing bearing needle rollers. Background Art

[0002] Needle roller refers to the rotating body on needle roller bearings, which are mainly used in various types of bearings. It is a roller bearing with cylindrical rollers. The rollers are thin and long like needles. This type of bearing has a high load-bearing capacity and a compact radial structure.

[0003] When the existing clamping device is in use, the table height is fixed.
