Description

Auxiliary device for sandblasting treatment of the inner surface of metal parts Technical Field

[0001] This utility model relates to the field of metal parts processing technology, specifically to an auxiliary device for sandblasting treatment of the inner surface of metal parts. Background Technology

[0002] Sandblasting is a surface treatment process that uses high-speed jets of abrasive to impact and grind the surface of an object. The principle is to use compressed air or mechanical power to drive the abrasive, forming a high-speed jet that acts on the workpiece surface to remove impurities such as rust, scale, oil stains, and old coatings, while simultaneously creating a uniform rough texture on the surface.

[0003] During sandblasting, small metal parts often shift or even fall due to the force of the blast, affecting processing efficiency and potentially damaging the parts. While using a tray can reduce the risk of falling, the tray's mesh or gaps can easily trap abrasive particles, forming sand buildup. This residual abrasive weakens the impact of subsequent sandblasting, leading to uneven stress on the part's surface, resulting in incomplete treatment or excessive wear in certain areas, severely impacting sandblasting accuracy and surface quality. Summary of the Invention

[0004] To solve the above-mentioned problems, this utility model proposes an auxiliary device for sandblasting the inner surface of metal parts, which can simultaneously support multiple small metal parts for sandblasting and prevents sand accumulation on the tray.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: an auxiliary device for sandblasting treatment of the inner surface of metal parts, comprising:

[0006] The tray has several sand-leaking holes evenly distributed on it.

[0007] The parts holder is magnetically fixed to the tray and comes in different sizes.

[0008] Furthermore, the edge of the tray is integrally formed with a limiting protrusion.

[0009] Furthermore, the sand-leaking hole is a frustum-shaped hole with an upper inner diameter larger than a lower inner diameter.

[0010] Furthermore, several micro-magnetic pieces are embedded in the tray between the sand-leaking holes, and the bottom surface of the part holder is made of magnetic material.

[0011] Furthermore, the edge of the part holder is provided with several sand-draining grooves.

[0012] Furthermore, the bottom surface of the sand table is evenly distributed with several anti-slip pads.

[0013] Compared with the prior art, the advantages of this utility model are: the device achieves quick disassembly and assembly and stable fixation of the parts holder through magnetic attraction, and the parts holders of different specifications can be flexibly adapted to a variety of small parts. With the reasonable space layout of the tray, multiple parts can be placed at the same time for efficient operation.

[0014] The sand-draining holes on the tray feature a design that is wider at the top and narrower at the bottom, which facilitates the collection of sand and accelerates its descent, reducing residual sand and clogging within the holes. Sand-draining grooves on the edge of the part holder guide residual sand from the part surface towards the draining holes, preventing sand from accumulating in the gap between the part and the part holder. Simultaneously, edge-limiting protrusions prevent sand from scattering, creating a pathway for rapid sand recovery and effectively preventing sand accumulation on the tray.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Referring to Figure 1, an auxiliary device for sandblasting the inner surface of metal parts includes: a tray 1, wherein the edge of the tray 1 is integrally formed with a limiting protrusion 4, which can effectively block the sand splashed during the sandblasting process, avoid the sand from falling from the edge of the tray 1 and causing waste, and at the same time reduce the pollution to the working environment.

[0022] Referring to Figures 1, 2, and 4, several sand-draining holes 2 are evenly distributed on the tray 1. The sand-draining holes 2 are frustum-shaped holes with an upper inner diameter larger than a lower inner diameter. The larger upper inner diameter makes it easier to collect sand, while the smaller lower inner diameter accelerates the falling of sand, which can reduce the residual blockage of sand in the hole and improve the sand recovery efficiency.

[0023] Referring to Figures 1 and 4, the part holder 3 is magnetically fixed to the tray 1 and comes in different sizes. Several miniature magnets 5 are embedded in the tray 1 between the sand-draining holes 2. The bottom surface of the part holder 3 is made of magnetic material. The miniature magnets 5 cooperate with the magnetic material bottom surface of the part holder 3, enabling quick assembly and disassembly and stable fixation of the part holder 3, adapting to the flexible replacement needs of parts of different sizes. Several sand-draining grooves 6 are provided on the edge of the part holder 3, which guide residual sand on the surface of the part to flow to the sand-draining holes 2 on the tray, preventing sand from accumulating in the gap between the part and the part holder 3, ensuring convenient cleaning after sandblasting.

[0024] Referring to Figures 2 and 3, the bottom surface of the tray 1 is evenly distributed with several anti-slip pads 7, which can increase the friction with the placement surface, prevent the tray 1 from sliding and shifting due to impact during sandblasting, and improve operational stability.

[0025] The specific implementation of this utility model is as follows: The tray 1 is placed stably on an external conveyor belt. The anti-slip pad 7 on the bottom of the tray 1 increases friction and prevents slippage during sandblasting. A suitable part holder 3 is selected according to the specifications of the small metal parts to be processed. The magnetic material on the bottom of the part holder 3 is used to attract and fix it to the micro-magnetic piece 5 embedded between the sand-draining holes 2 on the tray 1, enabling rapid installation of the part holder 3. After placing the parts one by one on the part holder 3, the conveyor belt can be started to drive them through the sandblasting equipment to sandblast the inner surface of the parts. During sandblasting, the limiting protrusion 4 on the edge of the tray 1 blocks splashed sand, preventing sand from scattering from the edge of the tray 1. Residual sand on the surface of the parts flows through the sand-draining groove 6 on the edge of the part holder 3 to the tray 1, and then falls and is collected through the evenly distributed sand-draining holes 2 on the tray 1. The larger inner diameter of the upper end of the sand-draining holes 2 facilitates the collection of sand, while the smaller inner diameter at the lower end accelerates the fall of sand, reducing residual blockage in the holes. The entire process is efficient and facilitates sand recovery.
