Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, specifically a multi-functional sandblasting machine for metal surface treatment. Background Technology

[0002] Sandblasting is a surface treatment process that uses compressed air to propel abrasive particles at high speed onto the surface of a workpiece, altering its appearance or shape. This technology is widely used in metal processing, welding, and flaw detection. In particular, when treating the surface of some metal workpieces, the abrasive can impact and cut the surface, giving it a certain degree of cleanliness and varying roughness, thereby improving the mechanical properties of the workpiece.

[0003] When using existing multi-functional sandblasting machines for metal surface treatment, taking cylindrical metal workpieces as an example, most sandblasting machines use clamping components such as three-jaw chucks to hold the cylindrical workpiece from the outside. With this method of positioning and fixing the metal workpiece, part of the outer wall surface will be blocked by the clamping components, resulting in incomplete sandblasting. At the same time, in order to avoid a large number of fine dust particles polluting the production environment inside the workshop, the staff also need to connect external dust collection equipment to purify the dust-laden gas before discharging it. This prolongs the processing flow of metal workpieces to a certain extent, increases the processing difficulty of metal workpieces, and is also a considerable burden on the staff, which is not conducive to the progress of metal surface treatment work.

One end of the ball screw 192 extends through to the outside of the guide groove 191 and is fixedly connected to a driven bevel gear 197. One side of the driven bevel gear 197 meshes with the driving bevel gear 198. Figure 4 , Figure 6 As shown, the first motor 199 and the driving bevel gear 198 can drive multiple driven bevel gears 197 and ball screws 192 to rotate synchronously. The multiple driven bevel gears 197 then drive the second L-shaped seats 193 to move closer or further apart through the ball screws 192. In this way, the metal workpiece can be positioned and fixed without obstructing the outer wall surface, and the incomplete sandblasting treatment of the metal workpiece caused by the obstruction of the components is avoided.

[0031] The guide groove 191 has a boss 26 at its top, and a telescopic cover 27 is provided above the boss 26. The telescopic cover 27 is fixedly installed on the outside of the first L-shaped rod 195.

[0039] Working principle: First, the operator can position and fix the metal workpiece using the inner support component 19 without obstructing the outer wall surface, thus avoiding incomplete sandblasting due to component obstruction and ensuring uniform sandblasting of the outer wall surface of the metal workpiece. Then, the lifting component 13, in conjunction with the adjusting component 21, allows the sandblasting gun 12 to complete the sandblasting of each surface of the metal workpiece. During this process, the dust collection component 10 can collect and extract the dust particles generated during sandblasting into the filter box 9, thus preventing dust-laden gas from polluting the processing environment of the workshop. Then, the dust-laden gas is filtered by the purification component 29 before being discharged, avoiding direct discharge that could pollute the external environment and improving environmental protection. This system integrates multiple functions such as workpiece clamping, sandblasting gun adjustment, abrasive supply, and dust collection and purification, making it convenient and easy to operate.
