Spray head adjusting mechanism

Abstract

The invention belongs to the technical field of spray head adjusting mechanisms, and relates to a spray head adjusting mechanism which comprises a bottom plate, a motor arranged on the bottom plate, acoupler connected with the output end of the motor, a first straight shaft fixedly connected with the coupler, a first bevel gear fixedly connected with the first straight shaft, a second bevel gearengaged with the first bevel gear, a second straight shaft fixedly connected with the second bevel gear, a turntable fixedly connected with the second straight shaft, a connecting rod hinged to the turntable and a spray head assembly hinged to the bottom plate. The connecting rod for driving the spray head assembly to rotate around the bottom plate is hinged to the spray head assembly. The spray head adjusting mechanism further comprises a first electric push rod and a second electric push rod, the first electric push rod is fixed on the bottom plate, and the output end of the second electricpush rod is hinged to the side surface of the bottom plate. The spray head adjusting mechanism can adjust the spray angle of a spray head and also can adjust the spray distance of the spray head.

Description

technical field [0001] The invention relates to the technical field of nozzle adjustment, in particular to a nozzle adjustment mechanism. Background technique [0002] In recent years, Professor Liu Xiaochu of Guangzhou University has proposed a new method of enhanced grinding processing that integrates surface strengthening and grinding micro-cutting. The abrasive composed of steel balls, grinding powder and grinding liquid is sprayed on the bearing sleeve by high-pressure gas. The surface of the ring can obtain a surface strengthening layer with better mechanical properties; however, the existing equipment is to set the injector in the cage and then fix it through threaded connection. If it is necessary to adjust the spray angle, it can only be adjusted manually. Angle, since it is obviously not accurate enough to adjust the spray angle without reference to human feeling, it is also very inconvenient to adjust the spray angle by constantly turning the screw.

AI Technical Summary

Problems solved by technology

The central rod of this device is fixed between the base and the threaded connection, and the angle is adjusted by feeling. The fixing structure is more complicated. At the same time, due to the particularity of the injector, this mechanism cannot be well applied in the field of intensive grinding.

[0004] Another example is an invention patent named "sandblasting machine". The sandblasting machine described in this invention includes: a sandblasting tank, a driving device and a nozzle assembly, etc., wherein the sandblasting tank and the nozzle assembly are connected, and the nozzle assembly is arranged obliquely. And take the apex of the oblique line formed by the oblique setting as the center of the circle to rotate, and the nozzle assembly is driven by the driving device, which can realize uniform and automatic sandblasting treatment; this mechanism achieves a large area of ​​sandblasting coverage through the rotation of the nozzle assembly , can not change the angle of spraying, let alone automatically adjust the spraying distance of the nozzle, so it is not suitable for the field of intensive grinding processing
