Description

Technical Field

[0001] This utility model belongs to the field of micro-arc oxidation technology, specifically relating to a micro-arc oxidation fixture suitable for processing parts of various shapes. Background Technology

[0002] Micro-arc oxidation (MAO), also known as plasma electrolytic oxidation (PEO), is an advanced surface treatment technology developed based on anodic oxidation. This technology can grow high-performance ceramic films in situ on metal surfaces, significantly improving the wear resistance, corrosion resistance, and other physical properties of the processed parts. However, in practical applications, the design of the micro-arc oxidation fixture is crucial, as it directly affects the good connection between the processed part and the cathode, as well as the uniform distribution of the coating.

[0003] Currently, the common processing methods are aluminum wire winding and screw fixing. Although aluminum wire winding is simple to operate, the aluminum wire is easy to break, causing the processed part to fall off. The screw fixing method requires drilling holes in the workpiece to make threads, but from the perspective of structural and aesthetic reasons, not all workpieces can be drilled. This micro-arc oxidation method is too limited and single, and is not suitable for most workpieces. Moreover, in the existing technology, the fixtures used for micro-arc oxidation treatment often only have a single function of adjusting the height of the fixture, and cannot achieve full-range spatial position adjustment.

[0004] To address the above problems, this utility model proposes a micro-arc oxidation fixture suitable for processing parts of various shapes. It can not only stabilize the processed parts, but also allow for all-round spatial position adjustment, thus enabling the processing of multiple parts of different shapes. Utility Model Content

Detailed Implementation

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] A micro-arc oxidation fixture suitable for processing parts of various shapes, as shown in the attached image. Figure 1-6As shown, the device includes a hanging bracket 1, with a hook 2 connected to the top of the hanging bracket 1. The hanging bracket 1 is composed of two circular rods 3, arranged from the inside to the outside, and connected and fixed by a connecting rod 4. The circular rods 3 have several mounting holes 5, and adjustment components are installed in the mounting holes 5. The adjustment components are connected to a height adjustment rod 6. The bottom of the height adjustment rod 6 on the inner circular rod 3 is threadedly connected to a threaded connecting rod 8, the size of which can be selected according to the size of the threaded hole of the workpiece. The height adjustment rod 6 on the outer circular rod 3 is fixedly equipped with a clamping member 7. The clamping member 7 includes a clamping plate 15 fixedly connected to the height adjustment rod 6, and the clamping plate 15 has a clamping opening 16. A plurality of fixing protrusions 17 are fixedly provided on one inner side of the opening 16, and a plurality of bolts 18 corresponding to the positions of the fixing protrusions 17 are threaded through the other side. In this embodiment, the fixing protrusions 17 are tapered. When the micro-arc oxidation workpiece itself has a threaded hole or a threaded hole can be made in the workpiece itself, a threaded connecting rod 8 can be used for connection. The workpiece is connected to the threaded connecting rod 8 through the threaded hole, and the threaded connecting rod 8 is fixed to the bracket 1 through the height adjustment rod 6. When the micro-arc oxidation workpiece itself does not have a threaded hole, a clamping member 7 is selected as the connecting member. The workpiece is placed in the clamping opening 16 of the clamping plate 15 and closely attached to the fixing protrusions 17. At the same time, the bolts 18 are tightened to clamp and fix the workpiece.

[0028] Specifically, the adjustment assembly includes an internal gear ring 9, a gear ring 10, and a mounting sleeve 11. The internal gear ring 9 is fixedly installed in the mounting hole 5. The gear ring 10 is fixedly sleeved on the outside of the mounting sleeve 11. The gear ring 10 and the internal gear ring 9 are in clearance fit. A limiting ring 12 is fixedly installed on the bottom of the adjustment assembly inside the mounting hole 5. The adjustment method is as follows: by lifting the mounting sleeve 11 upwards, rotating it to the desired position, and then placing it back into the internal gear ring 9, the gear ring 10 sleeved on its outside engages with the internal gear ring 9 to achieve a fixed limit. At the same time, by fixing the limiting ring 12 at the bottom of the adjustment assembly, the installation sleeve 11 can be prevented from falling off when placed back into the internal gear ring 9, and it is limited. The adjustment of the adjustment assembly can solve the problem of interference between the relative positions of the workpieces and increase the adaptability of the fixture.

[0029] Specifically, the inner side of the mounting sleeve 11 is slidably connected to the height adjustment rod 6. The height adjustment rod 6 has several through holes 13 evenly distributed from top to bottom. The top of the mounting sleeve 11 is provided with a slot 14. The height adjustment rod 6 is inserted into the through hole 13 by a pin 20 and the pin 20 is engaged in the slot 14 to achieve height adjustment. The adjustment method is to lift the height adjustment rod 6 upwards, and when it is adjusted to the desired position, insert the pin 20 into the corresponding through hole 13 and engage the pin 20 in the slot 14 to achieve height adjustment.

[0030] Furthermore, to facilitate the adjustment of the components, the mounting sleeve 11 is fixedly fitted with an adjusting turntable 19 above the ring rod 3, which can be used for adjustment when needed.

[0031] Work process

[0032] First, the pre-treated workpiece is fixed with a suitable connector (clamping part 7 or threaded connecting rod 8) according to its shape. (During this process, if the workpieces interfere with each other in relative position after being fixed, the adjustment can be made by adjusting the components. The adjustment process is as follows: lift the mounting sleeve 11 upwards, rotate it to the required position, and place it back into the inner gear ring 9. The gear ring 10 on its outer side engages with the inner gear ring 9 to achieve fixed positioning.) The hanger is suspended in the micro-arc oxidation equipment through the hook 2 to ensure the stability of the hanger. Second, according to the required height of the workpiece micro-arc oxidation, the pin 20 is inserted into the corresponding through hole 13 of the height adjustment rod 6, and the pin 20 is engaged in the slot 14 of the mounting sleeve 11 to fix the height adjustment rod 6, thereby adjusting the required height of the workpiece. Finally, the micro-arc oxidation equipment is started to perform micro-arc oxidation treatment on the workpiece. After the treatment is completed, the equipment is turned off, and the hanger and workpiece are removed. (It should be noted that during the micro-arc oxidation process, it is not necessary to place all the height adjustment rods 6 in the mounting holes 5. The selection can be made according to the actual number of parts to be processed.)
