Inner and outer ring cross bearing

Abstract

The invention belongs to the technical field of application of accessories such as a laser level meter and a laser wall adhering instrument, and particularly discloses an inner and outer ring cross bearing, which consists of a transverse positioning block, and a first support adjusting assembly and a second support adjusting assembly which are matched with the transverse positioning block for use.The inner and outer ring cross bearing has the beneficial effects that 1, the whole inner and outer ring cross bearing is of a reasonably designed combined structure, is convenient to assemble and maintain, can be used for the second time, realizes high-precision adjustment of a gap, and also reduces the cost investment of a user; and 2, the production cost is low, the inner and outer ring crossbearing can be machined on an original domestic machine, the required machining precision can be achieved without high machine tool machining, and the popularizing rate is high.

Description

Technical field [0001] The invention belongs to the technical field of application of accessories such as laser levelers and laser wall sticking instruments, and specifically relates to an inner and outer ring cross bearing. Background technique [0002] In the production process of laser level, laser wall sticking instrument, laser sticking to the ground, the bearing gap between the inner and outer ring (cross shaft) is known as the heart of the level. The gap between the bearings of the inner and outer rings (cross shaft) is directly related to the accuracy of the product's light. Too tight or too loose will not work. The ideal state is that the gap is equal to the accuracy gap of the bearing itself, that is, the natural gap. [0003] At present, every domestic manufacturer of laser instruments relies on the hands of skilled workers to assemble the inner and outer rings (cross shaft), and adjust the gap by adjusting the tightness of the left and right screws, resulting in unstabl...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic manufacturers of laser equipment rely on skilled workers to assemble the inner and outer rings (cross shafts), and adjust the gap by adjusting the left and right screws, resulting in unstable assembly quality and low production efficiency. At the same time, some The manufacturer directly seals the inner and outer rings of the bearing with the inner and outer rings (cross shaft) with glue for one-time sealing, which indeed controls the gap, but also causes serious waste. Once any of the four bearings loses quality The problem is that the inner and outer rings (cross shafts), including bearings, and even the whole machine are scrapped, which increases the user's cost input, and this is an urgent problem to be solved at present.
