Description

Technical Field

[0001] This utility model relates to the field of micro-arc oxidation technology, specifically a micro-arc oxidation rapid mold changing mechanism. Background Technology

[0002] Micro-arc oxidation is a new technology for in-situ growth of ceramic films on metal surfaces. It involves using high voltage and high current in an electrolyte solution to induce micro-arc discharge on the metal surface, creating a high-temperature and high-pressure environment that promotes a chemical reaction between the metal and oxygen in the electrolyte. This results in the formation of a ceramic oxide film on the metal surface with good wear resistance, corrosion resistance, insulation, and high hardness, effectively improving the surface properties and service life of metal materials.

[0003] When performing micro-arc oxidation, a mold is needed to fix and mount the workpiece. Since the workpiece has different shapes, different molds are required. When processing workpieces with different shapes, the original mold is usually removed and the required mold is installed under the hanger. The mold removal and replacement process is time-consuming, labor-intensive and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a micro-arc oxidation rapid mold changing mechanism, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A micro-arc oxidation rapid mold changing mechanism includes a hanger, an adjustment mechanism below the hanger, and two vertically extending rods symmetrically arranged below the adjustment mechanism. The adjustment mechanism is used to drive the two rods to move closer or further apart. The bottom end of each rod is fixed with a mounting base, and a vertically extending and rotatable shaft is installed below each mounting base. The bottom end of each shaft is fixed with a clamping seat. Two clamping heads A are fixed on one side of each clamping seat, and a V-shaped groove is provided on the other side of each clamping seat. Clamping heads B are fixed on both sides of the V-shaped groove.

[0007] Therefore, by rotating the adjusting shaft, the clamping seat can be quickly switched between the two clamping heads A being in the clamping working position and the two clamping heads B being in the workpiece clamping position. This eliminates the need to disassemble or replace the entire mold, allowing it to directly adapt to workpieces of different shapes and significantly reducing mold change time.

[0008] Furthermore, each mounting base has a mounting hole at its bottom end, and each mounting base has a limiting hole communicating with the mounting hole. The top end of the shaft is rotatably mounted in the mounting hole, and a circular limiting seat is rotatably mounted in the limiting hole. The two circular limiting seats are fixedly connected to the top end of the shaft on the corresponding side.

[0009] Furthermore, a first insertion hole is provided on one side of the outer peripheral wall of the circular limiting seat, and a second insertion hole is provided on the other side. The first and second insertion holes are arranged symmetrically. The side of the mounting seat is provided with a sliding hole that communicates with the limiting hole. An insertion rod is slidably inserted into the sliding hole. When the two insertion rods are respectively inserted into the corresponding first insertion hole, the clamping heads A on both sides cooperate to clamp the rectangular workpiece. When the two insertion rods are respectively inserted into the corresponding second insertion hole, the clamping heads B on both sides cooperate to clamp the round rod-shaped workpiece.

[0010] Furthermore, each insertion rod has a handle fixed to its outer end on the mounting base, and a spring is fitted around the outside of each insertion rod. One end of the spring is fixed to the handle, and the other end is fixed to the outer surface of the mounting base.

[0011] Furthermore, both clamping head A and clamping head B are cone-shaped with pointed tips.

[0012] Furthermore, the adjustment mechanism includes a guide seat, a bidirectional screw rod, and a nut seat. The guide seat is located below the hanger and has a bottom groove below it. The bidirectional screw rod is rotatably installed in the bottom groove. Two nut seats are symmetrically and slidably installed on both sides of the bottom groove, and the two nut seats are threadedly matched and fitted on both sides of the bidirectional screw rod. The two vertical rods are respectively fixed on the bottom end of the corresponding nut seats.

[0013] Furthermore, one end of the bidirectional screw extends through to the outside of the guide seat and is fitted with a torsion handle.

[0014] Furthermore, the hanger includes a plate base, connecting rods, and a hanging ring. The plate base is fixed to the top of the guide seat, and connecting rods are evenly distributed on the top of the plate base. The top of the connecting rods are all fixed with a hanging ring, which is used in conjunction with the hook below the hanger.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] This invention allows the clamping head to quickly switch between the two clamping heads A being in the working position and the two clamping heads B being in the workpiece position by rotating the adjusting shaft. This eliminates the need to disassemble or replace the entire mold, directly adapting to workpieces of different shapes and significantly reducing mold change time.

[0017] In the specific switching process of this utility model, by pinching the handle and pulling the plug outward, the plug is disengaged from one of the sockets. At this time, the spring is compressed and stored. Then, the shaft is rotated to misalign the plug with the socket and loosen the handle. Under the elastic restoring action of the spring, the plug is pushed inward. The end of the plug will abut against the outer wall of the circular limit seat. Then, the shaft is rotated until the plug is aligned with the other socket. Under the elastic force of the spring, the plug is pushed to match and insert into the socket, realizing the self-alignment of the plug and the socket without manual alignment, thus further improving the switching efficiency.

[0025] Please see Figures 1-4 This utility model provides a micro-arc oxidation rapid mold changing mechanism.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0027] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0028] The quick mold changing mechanism includes a hanger 1, an adjustment mechanism 2 below the hanger 1, and two vertically extending rods 3 symmetrically arranged below the adjustment mechanism 2. The adjustment mechanism 2 is used to drive the two vertical rods 3 to move closer or further apart. The bottom ends of the two vertical rods 3 are fixed with mounting bases 4. The bottom of the two mounting bases 4 are each equipped with a vertically extending and rotatable shaft 5. The bottom ends of the two shafts 5 are each fixed with clamps 6. Two clamping heads A7 are fixed on one side of the two clamps 6. The other side of the two clamps 6 is provided with a V-groove 81. Clamping heads B8 are fixed on both sides of the V-groove 81.

[0029] In use, the quick mold change mechanism involves hanging the hanger 1 below the bracket. When a rectangular workpiece needs to be clamped, the two adjusting shafts 5 are rotated to align the two clamping heads A7 on both sides. The rectangular workpiece is then placed between the clamping heads A7. The adjusting mechanism 2 is then operated to bring the clamping heads 6 closer together until each clamping head A7 contacts the outer surface of the rectangular workpiece. Figure 5 As shown, this allows for the clamping of rectangular workpieces. Then, the workpiece is placed into the electrolyte tank below the hanger for micro-arc oxidation processing.

[0030] When clamping a cylindrical workpiece, rotate the two adjusting shafts 5 to rotate the two clamping seats 6 until the clamping heads B8 on both sides are aligned. Then, place the cylindrical workpiece between the clamping heads B8 on both sides. Subsequently, operate the adjusting mechanism 2 to move the clamping seats 6 closer together until each clamping head A7 abuts against the outer surface of the cylindrical workpiece. Figure 6 As shown, this enables the clamping of a cylindrical workpiece.

[0031] like Figure 3 and Figure 4 As shown, each mounting base 4 has a mounting hole 41 at its bottom end and a limiting hole 42 communicating with the mounting hole 41. The top end of the shaft 5 is rotatably mounted in the mounting hole 41, and a circular limiting seat 51 is rotatably mounted in the limiting hole 42. The two circular limiting seats 51 are fixedly connected to the top end of the shaft 5 on the corresponding side, and the diameter of the circular limiting seat 51 is larger than the inner diameter of the mounting hole 41. The rotational cooperation between the circular limiting seat 51 and the limiting hole 42 plays a role in preventing the shaft 5 from falling downward and coming out of the mounting hole 41.

[0032] The circular limiting seat 51 has a first insertion hole 511 on one side of its outer peripheral wall and a second insertion hole 512 on the other side. The first insertion hole 511 and the second insertion hole 512 are arranged symmetrically. The side of the mounting seat 4 has a sliding hole 43 that communicates with the limiting hole 42. Insert rods 9 are slidably inserted into the sliding hole 43. When the two insert rods 9 are respectively inserted into the corresponding first insertion hole 511, the clamping heads A7 on both sides cooperate to clamp the rectangular workpiece. When the two insert rods 9 are respectively inserted into the corresponding second insertion hole 512, the clamping heads B8 on both sides cooperate to clamp the round rod-shaped workpiece.

[0033] Each insertion rod 9 has a handle 91 fixed to its end located on the outside of the mounting base 4. Each insertion rod 9 is fitted with a spring 92. One end of the spring 92 is fixed to the handle 91, and the other end is fixed to the outer surface of the mounting base 4.

[0034] During the specific switching process, by pinching the handle 91 and pulling the insertion rod 9 outward, the insertion rod 9 is disengaged from one of the insertion holes. At this time, the spring 92 is compressed and stored. Then, the shaft 5 is rotated to misalign the insertion rod 9 with the insertion hole, and the handle 91 is loosened. Under the elastic restoring action of the spring 92, the insertion rod 9 is pushed inward. The end of the insertion rod 9 will abut against the outer wall of the circular limit seat 51. Then, the shaft 5 is rotated until the insertion rod 9 is aligned with the other insertion hole. Under the elastic force of the spring 92, the insertion rod 9 is pushed to match and insert into the insertion hole, realizing the self-alignment of the insertion rod 9 and the insertion hole. No manual alignment is required. The operation is simple and convenient, and the two working surfaces of the clamp 6 can be quickly switched.

[0035] In addition, the clamping head B8 is placed on the inner wall of the V-groove 81 so that the distribution points of the clamping head B8 are adapted to the outer wall of the cylindrical workpiece, ensuring the firmness of the clamping.

[0036] Meanwhile, when clamping a rectangular workpiece, two clamping heads A7 are set on the same side to achieve four-point clamping of the rectangular workpiece, ensuring the firmness of the rectangular workpiece when clamped.

[0037] like Figure 3 As shown, both clamping heads A7 and B8 are cone-shaped. The tips of clamping heads A7 and B8 are in contact with the workpiece surface, resulting in a small contact area and avoiding excessive obscuring of the workpiece's outer surface, which would affect the processing.

[0038] like Figure 2 As shown, the adjustment mechanism 2 includes a guide seat 21, a bidirectional screw rod 22, and a nut seat 23. The guide seat 21 is located below the hanger 1. The guide seat 21 has a bottom groove 211 below it. The bidirectional screw rod 22 is rotatably installed in the bottom groove 211. Two nut seats 23 are symmetrically and slidably installed on both sides of the bottom groove 211. The two nut seats 23 are threadedly matched and fitted on both sides of the bidirectional screw rod 22. Two vertical rods 3 are fixed on the bottom ends of the corresponding nut seats 23. One end of the bidirectional screw rod 22 extends through to the outside of the guide seat 21 and is equipped with a torsion handle 221.

[0039] By pinching the torsion handle 221 to adjust the double-ended screw rod 22, the rotating double-ended screw rod 22 drives the two nut seats 23 to move closer or further apart in the bottom groove 211, thereby providing adjustment drive for clamping and releasing the workpiece.

[0040] The hanger 1 includes a plate base 11, connecting rods 12, and a hanging ring 13. The plate base 11 is fixed to the top of the guide seat 21. Connecting rods 12 are evenly distributed on the top of the plate base 11. The top of the connecting rods 12 are all fixed with the hanging ring 13. The hanging ring 13 is used in conjunction with the hook below the hanger. By hanging the hanging ring 13 on the hook below the hanger, the whole unit can be combined with the hanger, which facilitates the lowering and raising of the workpiece.

[0041] The specific structure, model and coefficient indicators of all components in this utility model are its own technologies. As long as they can achieve the beneficial effects, they can be implemented. Therefore, they will not be described in detail.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
