Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing production, in particular to a fixing device used for linear bearing production. Background Art
[0002] Linear bearings are a type of linear motion system used in conjunction with cylindrical shafts for linear travel. Since the load-bearing ball is in point contact with the outer sleeve of the bearing, the steel ball rolls with minimal friction resistance, so linear bearings have low friction and are relatively stable. In the production process of linear bearings, the linear bearings need to be fixed before continuing with subsequent processing. Therefore, the effect of the fixation is directly related to the error size of the product processing, and is the key to ensuring the quality of linear bearings.
[0003] The current fixing device is not convenient for adjusting the fixed spacing, which means that it can only be used for bearings of fixed models and has a small range of use. In addition, most of the existing fixing devices are only fixed in the vertical direction, which causes the linear bearing to rotate during subsequent processing, resulting in production errors and affecting product quality. Moreover, the installation method of the existing fixing device is mostly fixed with bolts, which is not convenient for subsequent disassembly and position adjustment. Utility Model Content

The two mounting plates 14 are moved to a suitable position and fixed by the cooperation between the mounting holes 6 and the fixing nails. The side wall of the mounting plate 14 is equidistantly provided with a plurality of limiting holes 15.
[0028] A circular groove 16 is provided on the side wall of each slide groove 13, and a pull rod 17 is slidably connected to the inner wall of the circular groove 16, and one end of the pull rod 17 is fixedly connected to a limit rod 19, and the limit rod 19 passes through one of the limit holes 15; a first spring 18 is fixedly connected to the inner wall of each circular groove 16, and one end of the first spring 18 is fixedly connected to the side wall of the limit rod 19.
