Description

Technical Field

[0001] The utility model belongs to the technical field of fixtures and clamps, in particular to an adjustable surface treatment oxidation hanger. Background Art

[0002] The type and form of fixtures are determined by the shape of the part to be oxidized, the technical requirements for the oxide layer, the oxidation process, and the size of the equipment. Factories are typically equipped with both general-purpose and specialized fixtures. Fixtures provide stable support and fixturing, ensuring that the workpiece does not move or deform during processing. They also precisely position and secure the workpiece, ensuring accurate positioning and angles during processing.

[0003] When performing surface treatment on shell parts, clamping is often used. However, sometimes shell parts cannot be clamped from the outside, or the internal ribs are insufficient for internal clamping. Furthermore, a single oxidation fixture is often only suitable for one type of shell, seriously impacting production schedules. Utility Model Content

[0004] In response to the shortcomings in the relevant technology, the utility model provides an adjustable surface treatment oxidation hanger to simplify the structure of the oxidation hanger, so that the shell can be tightened from the inside to solve the technical problem that shell parts cannot be clamped from the outside or there are too few internal ring ribs to be clamped from the inside.

[0005] The utility model provides an adjustable surface treatment oxidation hanger, which supports a shell with a ribbed plate on the inner wall, and comprises:

[0006] The support rod is long and columnar;

[0007] A conductive hook, in a bent shape, mechanically and electrically connected to one end of the support rod, and located at the top of the support rod;

[0008] An upper support plate, wherein a first through hole is provided in the center of the upper support plate, and the support rod passes through the first through hole, so that the upper support plate is fixed to the support rod;

[0009] A lower support plate is located above the rib plate, a second through hole is provided in the center of the lower support plate, and both ends of the lower support plate are in contact with the rib plate;

[0010] The limit adjustment device is connected to the other end of the support rod, passes through the second through hole, and is connected to the lower support plate, so as to adjust the displacement of the lower support plate.

[0011] The conductive hook connects to the energized element, transmitting current. A limit adjustment device controls the displacement of the lower support plate, allowing it to move to a position that supports the housing. The upper support plate fits against the rib structure inside the upper half of the housing, providing support. Together, the upper and lower support plates support the housing, thus ensuring internal support for easy access.

[0012] In some embodiments, the limit adjustment device includes:

[0013] An adapter, in the shape of a double-headed stud, connected to the bottom end of the support rod and passing through the second through hole of the lower support plate;

[0014] The limiting component has a threaded hole at the center and is installed at the thread at one end of the adapter. The limiting component is located above the lower support plate and is adapted to the thread on the surface of the adapter.

[0015] One end of the limit adjustment device is connected to the support rod, and the other end passes through the lower support plate, connecting the lower support plate and the support rod together to form an adjustable surface treatment oxidation hanger.

[0016] In some embodiments, the limiting assembly includes a first fixing member and a gasket. When the first fixing member is rotated, the first fixing member and the gasket move downward along the thread of the adapter, pushing the lower support plate downward until it is tightly attached to the surface of the lower support plate, and both ends of the lower support plate are tightly attached to the rib plate.

[0017] The first fixing member is rotated to move downward along the thread, thereby pushing the lower support plate downward until the lower support plate is close to the rib plate of the shell. The two ends of the lower support plate support the shell tightly and fix the shell to the outside of the adjustable surface treatment oxidation rack.

[0018] In some embodiments, a threaded hole is provided at the bottom end of the support rod, and the threaded hole at the bottom end of the support rod is adapted to the thread at the other end of the adapter to connect the support rod to the adapter.

[0019] A threaded hole is provided at the bottom end of the support rod and a threaded adapter is provided at the other end of the adapter, so that the adapter can be tightened to the bottom end of the support rod to improve the stability of the structural connection.

[0020] In some embodiments, an external spline is provided on the support rod, and an internal spline is provided on the inner side of the first through hole. When the support rod passes through the first through hole, the external spline passes through the first through hole, and the support rod is rotated until the external spline is in contact with the internal spline, thereby limiting the upper support plate above the external spline of the support rod.

[0021] When the outer and inner splines are completely misaligned, the support rod can be passed through the first through hole. When the outer and inner splines are partially aligned, the upper support plate can be restrained above the outer splines. This can limit the displacement of the upper support rod and thus better support the housing.

[0022] In some embodiments, an adjustable surface treatment oxidation hanger further includes a second fixing member, wherein a plurality of fixing holes are provided near the position of the conductive hook near the support rod, and the second fixing member passes through the plurality of fixing holes to fix the conductive hook to the top of the support rod.

[0023] The second fixing piece fixes the conductive hook on the support rod, which is beneficial to improving the structural stability.

[0024] In some embodiments, both end edges of the upper support plate and both end edges of the lower support plate are arc-shaped.

[0025] The two end edges of the upper support plate and the two end edges of the lower support plate are configured to be arc-shaped, which can better adapt to the arc-shaped side surface of the shell.

[0026] Based on the above technical solution, in this embodiment of the utility model, the displacement of the upper support plate is limited by external splines, while the displacement of the lower support plate is adjusted by a limit adjustment device. The upper and lower support plates respectively contact the ribs of the shell, supporting and bracing the shell, thereby enabling the shell to be fixed to the adjustable surface treatment oxidation rack from the inside. The structure of the oxidation rack is optimized to accommodate shells with fewer internal ring ribs, expanding its range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] As attached Figure 1 and attached Figure 2 As shown, in an exemplary embodiment of the present invention, an adjustable surface treatment oxidation rack is provided. The adjustable surface treatment oxidation rack supports a shell having a ribbed inner wall, and includes:

[0046] Support rod 1 is long columnar.

[0047] The conductive hook 2 is bent and mechanically and electrically connected to one end of the support rod 1 , and is located at the top of the support rod 1 .

[0048] The upper support plate 3 has a first through hole 31 at its center, and the support rod 1 passes through the first through hole 31 to fix the upper support plate 3 on the support rod 1 .

[0049] The lower support plate 4 is located above the rib plate. A second through hole 41 is provided in the center of the lower support plate 4. Both ends of the lower support plate 4 are in contact with the rib plate.

[0050] The limit adjustment device is connected to the other end of the support rod 1 and passes through the second through hole 41 to be connected to the lower support plate 4 for adjusting the displacement of the lower support plate 4.

[0051] The conductive hook 2 is connected to the energizing element for transmitting current.

[0052] The lower support plate 4 is controlled by a position-limiting adjustment device, allowing it to move to a position where it can support the housing. The upper support plate 3 fits against the rib structure inside the upper half of the housing, providing support. The upper support plate 3 and lower support plate 4 work together to support the housing. This ensures that the housing is supported from the inside, facilitating easy access to the housing.

[0053] As attached Figure 8 As shown, the second through hole 41 of the lower support plate 4 is circular. During use, the position limiting adjustment device passes through the second through hole 41.

[0054] In some embodiments, as shown in the attached Figure 3 As shown, the limit adjustment device includes:

[0055] The adapter 6 is in the shape of a double-headed stud, connected to the bottom end of the support rod 1 , and passes through the second through hole 41 of the lower support plate 4 .

[0056] The limiting component has a threaded hole in the center and is installed at the thread on one end of the adapter 6. The limiting component is located above the lower support plate 4 and is adapted to the thread on the surface of the adapter 6.

[0057] One end of the limit adjustment device is connected to the support rod 1, and the other end passes through the lower support plate 4, connecting the lower support plate 4 and the support rod 1 together to form an adjustable surface treatment oxidation hanger.

[0058] In some embodiments, as shown in the attached Figure 2 , Attachment Figure 4 and attached Figure 5 As shown, the limiting assembly includes a first fixing member 7 and a gasket 8. When the first fixing member 7 is rotated, the first fixing member 7 and the gasket 8 move downward along the thread of the adapter 6, pushing the lower support plate 4 to move downward until it is close to the surface of the lower support plate 4, and the two ends of the lower support plate 4 are close to the rib plate.

[0059] The first fixing member 7 is rotated to move downward along the thread, thereby pushing the lower support plate 4 downward until the lower support plate 4 is close to the rib plate of the shell. The two ends of the lower support plate 4 support the shell tightly and fix the shell to the outside of the adjustable surface treatment oxidation rack.

[0060] The adapter 6 can be provided with different length specifications.

[0061] The first fixing member 7 comprises an aluminum nut.

[0062] The spacer 8 comprises an aluminum spacer.

[0063] In some embodiments, a threaded hole is provided at the bottom end of the support rod 1 , and the threaded hole at the bottom end of the support rod 1 is adapted to the thread at the other end of the adapter 6 to connect the support rod 1 and the adapter 6 .

[0064] The bottom end of the support rod 1 is provided with a threaded hole and the other end of the adapter 6 is threadedly adapted, so that the adapter 6 can be tightened to the bottom end of the support rod 1 to improve the stability of the structural connection.

[0065] In some embodiments, as shown in the attached Figure 6 and attached Figure 7 As shown, an external spline is provided on the support rod 1, and an internal spline is provided on the inner side of the first through hole 31. When the support rod 1 passes through the first through hole 31, the external spline passes through the first through hole 31, and the support rod 1 is rotated until the external spline fits with the internal spline, so as to limit the upper support plate 3 above the external spline of the support rod 1.

[0066] When the outer spline and the inner spline are completely misaligned, the support rod 1 can be passed through the first through hole 31. When the outer spline and the inner spline are partially aligned, the upper support plate 3 can be restrained above the outer spline. This can limit the displacement of the upper support rod 1 and thus better support the housing.

[0067] The first through hole 31 of the upper support plate 3 is set as a three-groove spline hole, and the support rod 1 is provided with a three-tooth spline. After the three-tooth spline passes through the three-groove spline hole, it is rotated a certain angle to achieve the limitation of the upper support plate 3.

[0068] In some embodiments, as shown in the attached Figure 9 and attached Figure 10 As shown, the adjustable surface treatment oxidation hanger also includes a second fixing member 5, and a plurality of fixing holes 21 are set near the position of the conductive hook 2 near the support rod 1. The second fixing member 5 passes through the plurality of fixing holes 21 to fix the conductive hook 2 to the top of the support rod 1.

[0069] The second fixing member 5 fixes the conductive hook 2 on the support rod 1, which is beneficial to improving the structural stability.

[0070] The second fixing member 5 includes matching bolts and nuts.

[0071] In some embodiments, both end edges of the upper support plate 3 and the lower support plate 4 are arc-shaped.

[0072] The two end edges of the upper support plate 3 and the two end edges of the lower support plate 4 are configured to be arc-shaped, so as to better adapt to the arc-shaped side surface of the shell.

[0073] As attached Figure 11 As shown, in the actual application process, the adjustable surface treatment oxidation hanger without the lower support plate 4 and the limit adjustment device is first passed through the interior of the shell, and the upper support plate 3 is fitted with the rib structure on the inner side of the upper half of the shell. The first fixing member 7 and the gasket 8 are installed on the adapter 6, and the lower support plate 4 is placed on the rib plate at one end of the shell, and then the adapter 6 is passed through the second through hole 41 of the lower support plate 4. By rotating the first fixing member 7, the first fixing member 7 pushes the lower support plate 4 to move downward to a limit and applies pressure until the lower support plate 4 supports the shell. The upper support plate 3 and the lower support plate 4 work together to tighten the shell from the inside with the help of the fewer ribs on the inside of the shell, thereby improving the stability of the shell on the adjustable surface treatment oxidation hanger.

[0074] The upper and lower support plates 3 and 4 are designed in various lengths, depending on the inner diameter of the housing, to accommodate housings of varying sizes. The support rod 1 fits within the first through-hole 31 of the upper support plate 3 of varying lengths. Adapters 6 of varying lengths fit within the second through-hole 41 of the lower support plate 4 of varying lengths.

[0075] Through the description of multiple embodiments of the adjustable surface treatment oxidation rack of the present invention, it can be seen that the adjustable surface treatment oxidation rack of the present invention has at least one or more of the following advantages:

[0076] 1. The external spline limits the displacement of the upper support plate, and the limit adjustment device adjusts the displacement of the lower support plate to optimize the structure of the oxidation rack. The assembled adjustable surface treatment oxidation rack is detachable, easy to maintain, and quick and simple to operate.

[0077] 2. The upper support plate and the lower support plate are respectively in contact with the ribs of the shell to support and tighten the shell, so that the shell can be fixed on the adjustable surface treatment oxidation hanger from the inside of the shell to improve stability.

[0078] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0079] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
