The invention solves the practical problem by adopting the following technical scheme:

the utility model provides a ripples machine guide rail slider cooperation position appearance self-adaptation mechanism is made to big scale basin, includes: at least four sliding block supporting units which are arranged on the guide rail in a sliding mode and used for supporting the wave pushing sliding frame to move along the direction of the guide rail; each sliding block supporting unit comprises a sliding block, the bottom of the sliding block is connected to the guide rail in a sliding mode, a sliding block seat is fixedly arranged at the top of the sliding block, the sliding block seat is rotatably installed with a sliding frame support through a hinge shaft, and a wave pushing sliding frame is fixedly arranged above the sliding frame support.

And an annular limiting clamping groove is axially formed in the hinge shaft, two limiting plates are respectively inserted into the left end and the right end of the limiting clamping groove, and the two limiting plates are respectively and fixedly arranged on the slider seats on the same side.

Furthermore, an adjustment gap is left between the carriage support and the slider holder in the direction of the hinge shaft axis.

And the sliding block is fixedly arranged on the sliding block seat through a bolt.

And a wave pushing plate is fixedly arranged below the wave pushing sliding frame.

And the limiting plate is fixedly arranged on the slider seat on the same side through a bolt.

And a guide rail seat is fixedly arranged below the guide rail.

The invention has the advantages and beneficial effects that:

1. the angle between the sliding block seat and the sliding frame support can be automatically adjusted by taking the hinge shaft as a center, and when the levelness of the guide rail installation has errors or the levelness changes due to foundation settlement and the like along with the use of equipment, the sliding block seat can adapt to the errors and the changes of the levelness.

2. The invention has the advantages that the adjusting gap is reserved, the sliding block seat can move along the axial direction of the hinge shaft along with the change of the position of the guide rail, and when the guide rail has errors in the horizontal direction or the parallelism of the guide rail changes along with the use of equipment, the sliding block seat can adapt to the parallelism errors of the guide rail.

3. According to the invention, each sliding block can be fully contacted with the guide rail through adjusting the levelness and the parallelism in the two freedom degree directions, so that the running stability of the wave making machine is ensured, and the service life of the guide rail sliding block is prolonged.

Detailed Description

The embodiments of the invention will be described in further detail below with reference to the accompanying drawings:

a big scale basin ripples quick-witted guide rail slider cooperation position self-adaptation mechanism, as shown in fig. 1 to 7, includes: at least four sliding block supporting units which are arranged on the guide rail in a sliding mode and used for supporting the wave pushing sliding frame to move along the direction of the guide rail; each sliding block supporting unit comprises a sliding block, the bottom of the sliding block is connected to the guide rail in a sliding mode, a sliding block seat is fixedly arranged at the top of the sliding block, the sliding block seat is rotatably installed with a sliding frame support through a hinge shaft, and a wave pushing sliding frame is fixedly arranged above the sliding frame support.

In this embodiment, an annular limiting slot is axially formed in the hinge shaft, two limiting plates are respectively inserted into the left end and the right end of the limiting slot, and the two limiting plates are respectively and fixedly mounted on the slider seats on the same side.

In this embodiment, an adjustment gap is left between the carriage support and the slider holder in the hinge shaft direction.
