Description

Novel biax guide structure

Technical Field

The utility model relates to the technical field of driver guide parts, in particular to a novel double-shaft guide structure.

Background

As drives have evolved, so too has the structure of sliding guide parts for the interior of the drives. The motor drives the screw rod to rotate so as to enable the sliding block to axially and linearly move, and therefore the related product has a reciprocating motion function. In order to ensure axial movement, the sliding block is required to be limited in the radial direction, so that the screw rod drives the sliding block to only perform axial movement.

The radial limit of the sliding guide part of the traditional driver is the surface limit of the part of the sliding block, the sliding gap between the sliding block and the matching piece also needs to ensure reasonable size and unchanged gap in the running process, the surface of the matching part sliding in contact with the limiting surface of the sliding block needs to ensure parallelism in the sliding direction of the sliding block, otherwise, the gap of the limiting surface in the moving process of the sliding block cannot be ensured unchanged, so that the radial serial movement of the sliding block causes the problems of failure of related products, abnormal sound, large swing amplitude and the like, and the surface limit has large sliding resistance due to large contact area, thereby causing the problems of unsmooth sliding, large noise and the like when the sliding block slides.

Aiming at the problems, the novel sliding guide device is innovatively designed on the basis of the original sliding guide.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model aims to provide a novel double-shaft guide structure, so that the sliding gap of the radial limit of a sliding block is stable and small, the sliding contact area is small, the resistance is small, the sliding operation is stable and the noise is low.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a novel biax guide structure, includes casing, lead screw slider and lead screw, lead screw slider built-in nut and lead screw assembly, and lead screw slider and lead screw integration still include in the inner chamber of casing: the guide rod is sleeved with the screw rod sliding block, and the screw rod sliding block is arranged in the inner cavity of the shell in a sliding way along the guide rod through screw rod driving;

the screw rod and the guide rod are mutually parallel.

Preferably, the surfaces, corresponding to the inner cavity of the shell, of the periphery of the screw rod sliding block are clearance surfaces.

Preferably, the guide rod is fixedly mounted on the end cover of the housing.

Preferably, the guide rod is in sliding clearance fit with the screw rod sliding block.

The utility model has the following beneficial effects:

1. the radial limiting gap of the screw rod slide block is stable and small due to double-shaft guiding, so that the whole swing of the product is small;

2. the double-shaft guide has small limiting gap, can be lubricated by lubricating oil and has less contact surface, so that the whole operation noise of the product is low;

3. the guide surface of the screw rod sliding block matched with the shell is not required to be parallel to the guide surface of the shell by double-shaft guide, so that the manufacturing difficulty and precision of the screw rod sliding block and the shell are reduced;

4. the manufacturing difficulty and the precision of the screw rod sliding block and the shell are reduced due to double-shaft guiding, so that the manufacturing cost of parts is reduced, and the product cost is reduced;

5. the double-shaft guide reduces the size of the screw rod sliding block, so that the whole size of the product is reduced, and the required installation space is smaller while the cost is reduced.
