Portable nozzle of sand blasting robot

Abstract

The invention discloses a portable nozzle of a sand blasting robot. The portable nozzle comprises a mechanical arm and a nozzle, wherein one side of the mechanical arm is rotatably connected to a spray tube, a mounting seat is welded and mounted in the middle of one side of the mechanical arm, a mounting groove communicates to the inner part of the mounting seat, the nozzle is arranged in the mounting groove, and chutes are symmetrically formed in two sides of one end of the mounting groove; the mounting seat is arranged on one side of the mechanical arm, the mounting grooves are formed in themounting seat, and the nozzle can be placed in the mounting grooves, so that the troublesome step of finding the nozzle if the nozzle needs to be replaced is cancelled, the consumed time is shortened, and the work efficiency is improved; slide blocks are symmetrically arranged on two sides of a mounting door, the slide blocks are slidably arranged in the chutes, and when the nozzle is placed in the mounting groove, a rotating plate is rotated to be locked to a rotating plate groove, so that the structure is stable; a buffer plate and a spring are arranged in the mounting groove, so that the buffer plate moves upward through the elastic force of the spring and the nozzle is fixed between the buffer plate and the mounting groove, and therefore, the influence of swinging generated by movement of the mechanical arm to the nozzle is avoided.

Description

technical field [0001] The invention relates to the technical field of sandblasting equipment, in particular to a portable spray head of a sandblasting robot. Background technique [0002] Sandblasting is a common surface treatment process. It uses high-speed sand flow to impact the workpiece to achieve the purpose of cleaning the surface of the workpiece and improving the mechanical properties of the surface. Due to the noise and dust pollution generated during the sandblasting process, more and more manufacturers are currently The sandblasting operation is completed by a sandblasting robot. In the prior art, the sandblasting robot is usually three-axis or four-axis. The degree of freedom of the sandblasting pen is not high, and it cannot be well adapted to workpieces with complex surfaces. The use of sandblasting robots is limited to a certain extent. The sandblasting robots in the prior art need to use nozzles of different calibers when sandblasting, but generally the noz...

[0002] Sandblasting is a common surface treatment process. It uses high-speed sand flow to impact the workpiece to achieve the purpose of cleaning the surface of the workpiece and improving the mechanical properties of the surface. Due to the noise and dust pollution generated during the sandblasting process, more and more manufacturers are currently The sandblasting operation is completed by a sandblasting robot. In the prior art, the sandblasting robot is usually three-axis or four-axis. The degree of freedom of the sandblasting pen is not high, and it cannot be well adapted to workpieces with complex surfaces. The use of sandblasting robots is limited to a certain extent. The sandblasting robots in the prior art need to use nozzles of different calibers when sandblasting, but generally the nozzles and the mechanical arms are separated, resulting in a certain amount of time spent on the nozzles and reduced efficiency. To this end, we propose a portable spray head for sandblasting robots to solve the above problems
