Description

hanger

The present invention relates to a hanger, and more particularly to a hanger for use in an anodizing process.

The hanger used in the anodizing process of the workpiece generally includes a plurality of holding portions. A plurality of slots engaged with the retaining portions are formed on the inner side wall of the workpiece to fix the workpiece. Since the oxidation density of the current density and solution density at the contact between the workpiece and the hanger is different from that of other parts of the workpiece, the oxide film formed by the oxide film formed at the contact between the workpiece and the hanger and the oxide film formed at other parts by the anodizing treatment Different, it will cause traces at the contact between the workpiece and the hanger. The contact area between the above-mentioned hanger and the workpiece is large, and the area of the trace generated at the contact between the workpiece and the hanger is also relatively large.

In view of the above, it is necessary to provide a hanger that reduces the area of the traces caused by the contact of the hanger.

A hanger for holding a workpiece having a threaded hole, the hanger comprising a hanger and a clamping assembly mounted on the hanger. The clamping assembly includes a snap member and a connector detachably disposed on the latch member. The connecting member includes a threaded portion that cooperates with the threaded hole of the workpiece and a spindle portion that is coupled to the threaded portion. The main shaft portion defines a retaining groove, and the engaging member is engaged in the retaining groove.

The above-mentioned hanger is fixedly connected to the workpiece by the connecting member, and then the engaging member is used to hold the connecting member To fix the workpiece, the contact area between the hanger and the workpiece is reduced, thereby reducing the area of the trace of the workpiece surface due to the contact of the hanger after anodization, and improving the appearance of the workpiece.

2 is a partial perspective assembled view of the workpiece loading device of the hanger shown in FIG. 1.

Figure 3 is a perspective view of the connector of the hanger shown in Figure 1.

Referring to FIGS. 1 and 2, the hanger 100 of the embodiment of the present invention is used to clamp the workpiece 500 during anodizing. The workpiece 500 is substantially in the shape of a square plate, and has two threaded holes (not shown) on one side and a groove (not shown) on the other side. It can be understood that the hanger 100 can also be used in processes such as chemical cleaning, electroplating, and the like.

The hanger 100 includes a hanger 10 and a clamping assembly 30 mounted on the hanger 10. The pylon 10 includes a pylon head 11, a main rod 13 and a strut assembly 15. The pylon head 11 is fixedly coupled to the main rod 13, and the strut assembly 15 is fixedly mounted on the main rod 13. The pylon head 11 includes a fixing portion (not shown) and a connecting portion 113. The fixing portion is composed of two hooks 111. The connecting portion 113 has a rectangular plate shape, and the two ends thereof are fixedly connected to the two hooks 111, respectively, so that the pylon head 11 has a U shape. The main rod 13 has an elongated rod shape and is installed at a position intermediate the connecting portion 113 of the hanger head 11. The strut assembly 15 includes a plurality of first strut 151 and a plurality of second strut 153. The first strut 151 is parallel to the second strut 153 and is sequentially spaced apart from the main strut 13. Both the first pole 151 and the second pole 153 are in the shape of a "work" shaped rod.

The clamping assembly 30 is mounted on the first pole 151 and the second pole 153 of the hanger 10. Clamp The assembly 30 includes a connecting member 31, a latching member 33 and a resisting member 35, and the connecting member 31 is adapted to the engaging member 33. Referring to FIG. 3 together, the connecting member 31 includes a main shaft portion 311, a connecting portion 312, and a threaded portion 313. The main shaft portion 311 has a substantially cylindrical shape, and an annular holding groove 3111 is opened at a middle portion thereof. The connecting portion 312 has a truncated cone shape, and is formed by extending one end of the main shaft portion 311 in the axial direction, and its size gradually decreases away from one end of the main shaft portion 311. The threaded portion 313 is formed by extending the connecting portion 312 away from one end of the main shaft portion 311 in the axial direction, and the threaded portion 313 is fitted with the threaded hole of the workpiece 500 to be fixedly coupled to the workpiece 500. In the present embodiment, the connecting member 31 is integrally formed.

The engaging member 33 includes a body 331 and an engaging portion 333 formed by bending from both ends of the body 331. The body 331 has a strip shape and is mounted on an end of the first pole 151 of the hanger 10. The engaging portion 333 has a substantially rectangular sheet shape, and an engaging groove 3331 is opened at one end thereof. The engaging groove 3331 is adapted to the inner wall of the retaining groove 3111 of the connecting member 31 to fixedly connect the connecting member 31 with the engaging member 33, thereby fixedly connecting the hanger 100 to the workpiece 500.

The resisting member 35 includes a main body 351 and a hook 353 attached to both ends of the main body 351. The main body 351 is strip-shaped and is mounted on the end of the second strut 153 of the pylon 10. The hook 353 is installed at two ends of the main body 351.

In the embodiment of the present invention, the main body 351 is made of a titanium alloy, the hook 353 is made of an aluminum alloy, and the hook 353 is detachably mounted at the two ends of the main body 351. Since the end of the hook 353 is relatively pointed and is easily corroded by the anodizing solution, the hook 353 of the aluminum alloy material with lower cost is beneficial to reduce the maintenance cost of the hanger 100, and the hook 353 is detachably mounted for easy replacement of the card. Hook 353. It can be understood that the hook 353 can also be integrally formed with the main body 351.

When the workpiece 500 is gripped, the two connecting members 31 are respectively fixedly connected to the two threaded holes of the workpiece 500, and then the connecting member 31 is engaged by the engaging member 33, and then the resisting member 35 is used. The hook 353 holds the recess of the workpiece 500, thereby causing the hanger 100 to fix the workpiece 500 at three points.

The hanger 100 of the embodiment of the present invention is screwed to the workpiece 500 by the connecting member 31, and then the engaging member 33 is used to clamp the connecting member 31 to fix the workpiece 500, thereby reducing the contact area between the hanger 100 and the workpiece 500, thereby reducing the anode. The appearance of the surface of the workpiece 500 due to contact with the hanger 100 after oxidation improves the appearance of the workpiece 500. Moreover, the screw hole of the workpiece 500 itself can be utilized, thereby avoiding additional grooves on the workpiece 500 to hold the workpiece, reducing the processing procedure and saving the processing cost.

It can be understood that the locking groove 3111 of the connecting member 31 can also be opened at the end of the main shaft portion 311 so that the end portion thereof has a hollow structure. Correspondingly, the engaging portion 333 of the engaging member 33 has a convex structure and the card. The slot 3111 is adapted. It can be understood that the resisting member 35 may not be provided. In this case, the workpiece 500 may be fixed together with the engaging member 33 by the three sets of connecting members 31.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
