Description

Technical Field

[0001] This invention relates to the field of anode ring mounting fixture technology, and more specifically, to a high-precision positioning and mounting fixture for anode rings after PEG100 maintenance. Background Technology

[0002] During the maintenance of PEG100 coating accessories, because the PEG100 ionization chamber is very small, only needle-nose pliers or similar tools can be used to install the anode ring. The structure of the anode ring can be found in [reference needed]. Figure 1 The ring-shaped structure serves as the anode ring, with 45-degree wings on both sides. An integral column is located on the outer wall, with a central hole at the end of the column furthest from the anode ring. A contact pin is installed within the ionization chamber. During installation, the anode ring is placed into the ionization chamber, and the contact pin is inserted into the central hole.

[0003] In the existing technology, the contact area between the needle-nose pliers and the anode ring is small, resulting in uneven force distribution and easy displacement, which makes it difficult to align the holes and damage the anode ring. The installation time is also long, so the installation fixture needs to be redesigned. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a fixture that reduces damage to the anode ring, provides stable clamping, and is convenient and quick to install.

[0005] To solve the above problems, the present invention adopts the following technical solution. A high-precision positioning and installation fixture for an anode ring after PEG100 maintenance includes a base that serves as a depth limiter, a chuck that is vertically mounted on the base, and a clamping groove extending towards the base and used for center positioning and clamping the anode ring at one end of the chuck away from the base. Inclined grooves that connect the clamping groove are formed on both sides of the clamping groove at the end of the chuck away from the base.

[0006] Preferably, the two sides of the clamping groove extend outward through the side wall of the clamp.

[0007] Preferably, the end of the clamping groove near the base is arc-shaped to fit the anode ring, and the lowest point of the arc is the center point of the arc.

[0008] Preferably, the angle between the inclined groove and the clamping groove is 45 degrees.

[0009] Preferably, the cross-section of the base is larger than the cross-section of the clamp.

[0010] Preferably, an elastic cushioning pad is installed on the side of the base near the clamp.

[0011] Preferably, a positioning seat is installed between the chuck and the base to concentrically position the entire fixture.

[0012] Preferably, the centers of the clamp, the clamping groove, the positioning seat, and the base are located on the same vertical line.

[0013] Preferably, the inclined groove is located on both sides of the center of the clamping groove.

[0014] Compared with the prior art, the present invention has the following advantages: (1) When using this fixture, the anode ring can be inserted into the clamping groove of the chuck for center clamping and positioning, which greatly increases the contact area with the anode ring; at the same time, the wings on both sides of the anode ring are embedded in the inclined grooves on both sides of the clamping groove, ensuring the consistency of the wing installation angle, improving the accuracy and stability of the anode ring positioning. Since the anode ring is center clamped and positioned, it is convenient to align the hole with the contact needle when the anode ring is installed in the ionization generating chamber, reducing damage to the anode ring and improving installation efficiency.

[0015] (2) The base can be placed against the outside of the ionization generator to limit the depth of the clamp and prevent damage to the anode ring caused by excessive installation depth.

[0016] (3) Inserting the positioning seat into the opening can quickly position the fixture, the center hole on the anode ring and the contact pin in the ionization chamber concentrically, making installation faster. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] refer to Figure 1This is a schematic diagram of the anode ring 1. The ring-shaped structure is the anode ring 1. There are 45-degree wings 13 on both sides of the anode. An integral column 11 is located on the outer wall, and a central hole 12 is formed at the end of the integral column 11 furthest from the anode ring 1. (Refer to reference) Figure 4 The ionization generating chamber 8 has an opening 81 at the top and a contact pin 82 installed at the bottom. During installation, the anode ring 1 needs to be placed into the ionization generating chamber 8 and the contact pin 82 needs to be aligned and inserted into the center hole 12. In order to improve installation efficiency and reduce damage to the anode ring 1, an anode ring 1 installation fixture is designed.

[0021] For details, please refer to Figure 1-2 A fixture for mounting an anode ring 1 after PEG100 maintenance includes a base 2 that serves as a depth limiter. A chuck 3 is vertically mounted on the base 2. At the end of the chuck 3 away from the base 2, a clamping groove 4 extends towards the base 2 and is used to center and clamp the anode ring 1. The clamping groove 4 extends outwards through the sidewalls of the chuck 3 on both sides. Inclined slots 5 are formed on both sides of the clamping groove 4 at the end of the chuck 3 away from the base 2 and connect to the clamping groove 4. During clamping, the anode ring 1 is inserted into the clamping groove 4. The outer wall of the anode ring 1 is arc-shaped and contacts the bottom of the clamping groove 4. To ensure the anode ring 1 is centered within the clamping groove 4, the end of the clamping groove 4 near the base 2 is designed to be arc-shaped to fit the anode ring 1, with the lowest point of the arc being the center point of the arc. In this way, the outer wall of the anode ring 1 can completely fit with the bottom of the clamping groove 4. With the positioning of the wing 13 by the inclined groove 5, the lowest point of the outer wall of the anode ring 1 away from the integral column 11 and the center point of the bottom of the clamping groove 4 are on the same vertical line, ensuring the concentricity of the two.

[0022] Since the angle between the wing 13 on the anode ring 1 and the horizontal line is 45 degrees, the angle between the inclined groove 5 and the clamping groove 4 is also designed to be 45 degrees. Of course, the depth of the inclined groove 5 needs to be set according to the depth of the clamping groove 4. Specifically, when the outer wall of the anode ring 1 is completely in contact with the bottom of the clamping groove 4, the wing 13 is also in contact with the inclined groove 5. The width of the inclined groove 5 is slightly larger than the width of the wing 13, just enough to ensure that the wing 13 is limited and does not deflect. Since the wing 13 on the anode ring 1 is located on both sides of the center of the anode ring 1, the inclined groove 5 also needs to be set on both sides of the center of the clamping groove 4.

[0023] The cross-section of base 2 is larger than that of chuck 3. Here, base 2 serves as a depth limiter. For details, please refer to [reference needed]. Figure 4After the anode ring 1 is gripped by the fixture, the fixture is inverted, and then the chuck 3 is inserted into the ionization chamber 8 through the opening 81. The side of the base 2 near the chuck 3 rests against the top of the ionization chamber 8 to prevent excessive insertion and damage to the anode ring 1. An elastic buffer pad 6 is installed on the side of the base 2 near the chuck 3. The buffer pad 6 can be made of elastic materials such as rubber or silicone, providing flexible contact with the top of the ionization chamber 8 and reducing damage. Furthermore, a positioning seat 7 is installed between the chuck 3 and the base 2 to concentrically position the entire fixture. Here, the shape of the positioning seat 7 is fitted with the shape of the opening 81 of the ionization chamber 8, and after the positioning seat 7 is inserted into the opening 81, the center points of the two are concentric. For example, if the opening 81 is circular, the positioning seat 7 is cylindrical; if the opening 81 is triangular, the cross-section of the positioning seat 7 is triangular, etc. The centers of the chuck 3, the clamping groove 4, the positioning seat 7, and the base 2 are located on the same vertical line. When the clamp 3 is inserted into the ionization chamber 8, the positioning seat 7 is also embedded into the opening 81, thus completing the concentric alignment of the entire fixture with the ionization chamber 8. Since the anode ring 1 is clamped in the center of the fixture, the central hole 12 on the anode ring 1 and the contact pin 82 at the bottom of the ionization chamber 8 are concentrically aligned and embedded.

[0024] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
