A nozzle adjustment mechanism

Abstract

The invention relates to a nozzle adjustment mechanism, which comprises a bottom plate, a motor installed on the bottom plate, a coupling connected to the output end of the motor, a first straight shaft fixedly connected to the shaft coupling, and a second straight shaft fixedly connected to the first straight shaft. A bevel gear, a second bevel gear meshing 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 on the turntable, and a hinged connection with the bottom plate The nozzle assembly; the connecting rod used to drive the nozzle assembly to rotate around the base plate is hinged to the nozzle assembly. The nozzle adjustment mechanism also includes 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 electric push rod is hinged to the side of the bottom plate. The spray head adjustment mechanism can realize the adjustment of the spray angle of the spray head, and can also realize the adjustment of the spray distance of the spray head, and belongs to the technical field of the spray head adjustment mechanism.

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.

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
