[0025] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 8The paint stripping fixture shown includes a housing 1, wherein the housing 1 is provided with a bracket 2, at least one paint stripping station 3 located on the bracket 2, wherein the paint stripping station 3 is provided with a housing 4 for accommodating a reactor 100, and a paint stripping gap 5, wherein the paint stripping gap 5 includes a first paint stripping gap 51 and a second paint stripping gap 52 respectively located on one side of the housing 4, wherein the first paint stripping gap 51 is for the pin 101 at one end of the reactor 100 to extend into, and the second paint stripping gap 52 is for the pin 101 at the other end of the reactor 100 to extend into. The utility model can effectively support the reactor, and paint stripping the pins of the reactor by using a paint stripping agent, thereby reducing the time and labor consumption of manual operation, and at the same time reducing the influence of changes in working conditions and workpiece size on thorough paint stripping. The utility model sets a paint stripping station, and after placing the reactor in the housing, the pins at both ends of the reactor are respectively extended into the first paint stripping gap and the second paint stripping gap, and the pins are soaked and stripped by using a paint stripping agent, without the need for manual paint scraping, thereby further improving the processing efficiency.

[0027] like Figures 1 to 8 In the paint stripping jig shown, the housing 4 extends downward from the bracket 2, and the housing 4 is provided with a housing cavity 40, a housing cavity opening 41, a supporting bottom plate 42, and a housing cavity side plate 43 arranged on the supporting bottom plate 42. Optionally, in some embodiments, the housing cavity opening is used to place or remove the reactor from the housing cavity, the supporting bottom plate is used to support the reactor and ensure its stability, the housing cavity side plate is used to enclose the reactor and provide support, and the arrangement of the supporting bottom plate and the housing cavity side plate ensures the stability and fixity of the reactor, the housing extends downward from the bracket, and the height of the upper end surface of the housing cavity is lower than the height of the upper end plane of the bracket, so the required volume of paint stripping agent is relatively less, and the height of the housing cavity side plate is used to lift the upper end surface of the housing cavity to prevent the paint stripping agent from immersing the housing cavity and stripping the reactor core.

[0028] Optionally, in some embodiments, the supporting bottom plate and the accommodating cavity side plate are integrally formed.

[0029] Optionally, in some embodiments, the supporting bottom plate and the accommodating cavity side plate are connected by welding.

[0030] like Figures 1 to 8In the paint stripping jig shown, the bracket 2 is provided with a bracket first connection end 21, the housing 4 is provided with a housing connection end 410, and further includes a fastener 6 passing through the bracket first connection end 21 and the housing connection end 410, so that the bracket 2 is tightly connected to the housing 4. Optionally, in some embodiments, the housing connection end is located on the housing, and is used to connect with the bracket first connection end on the bracket to ensure the stability and correct position of the connection, thereby limiting the movement of the housing from the bracket, ensuring the structural stability and working reliability of the jig, and the operator can further adjust the size of the housing cavity according to the working conditions and the size of the reactor.

[0031] Optionally, in some embodiments, the required bracket size can be directly replaced according to the size of the reactor, thereby selecting a suitable accommodating cavity.

[0032] Optionally, in some other embodiments, the size of the accommodating cavity can be changed according to the size of the reactor. Specifically, since the extension length of the accommodating cavity side plate, the distance between two oppositely arranged accommodating cavity side plates, and the height of the accommodating cavity side plates are relatively fixed in the accommodating cavity, the width and height of the accommodating cavity are fixed. The operator can adjust the extension length of the supporting bottom plate to adjust the overall extension length of a single accommodating cavity.

[0033] Optionally, in some other embodiments, the accommodating shell and the bracket can be connected by riveting, welding, threaded connection, snap-fit, magnetism, etc.

[0034] Optionally, in this embodiment, the accommodating shell and the bracket are connected by riveting.

[0035] like Figures 1 to 8 In the paint stripping jig shown, the accommodating chamber side panel 43 includes a first accommodating chamber side panel 431 and a second accommodating chamber side panel 432 , the height of the first accommodating chamber side panel 431 is greater than the height of the second accommodating chamber side panel 432 , and the accommodating shell connecting end 410 is located on the first accommodating chamber side panel 431 .

[0036] Specifically, two oppositely disposed first accommodating chamber side plates and two oppositely disposed second accommodating chamber side plates enclose the accommodating chamber to provide a stable and safe processing environment, ensure the efficiency and accuracy of the paint stripping work, effectively protect the reactor from external interference and prevent the paint stripping agent from immersing the accommodating chamber and stripping the reactor magnetic core, and the supporting bottom plate is connected to the lower side of the accommodating chamber side plate and provides a stable support platform to ensure the stability of the position of the reactor in the accommodating chamber. Optionally, in some embodiments, the accommodating chamber is arranged in a rectangular parallelepiped.

[0037] Further, as a preferred embodiment of the utility model but not limiting, when the liquid level of the paint stripping agent is lower than the upper end surface of the second accommodating chamber side plate, the setting of the accommodating chamber plays a positioning role, preventing the paint stripping agent from immersing the accommodating chamber and stripping the reactor core, thereby affecting the insulation of the reactor core. The structure and design of the utility model help to improve the efficiency and accuracy of paint stripping, ensure that the paint stripping of the pins is thorough and uniform, and thus provide good electrical contact and transmission performance.

[0038] like Figures 3 to 8 In the paint stripping jig shown, the bracket 2 is provided with a positioning member 7, and the positioning member 7 is provided with a positioning rib 71 extending into the accommodating cavity 40, and the positioning rib 71 is vertically arranged and extends in a direction away from the first accommodating cavity side plate 431, and the positioning rib 71 is also provided with a positioning baffle 711 extending into the first paint stripping gap 51 and / or the second paint stripping gap 52. Optionally, in some embodiments, the positioning rib is used to provide positioning and directional guidance for the reactor to ensure the correct position of the reactor in the first paint stripping gap and / or the second paint stripping gap. The pin has a certain ductility and elasticity, and the pin can be slightly bent or stretched under force or external action. The positioning baffle can prevent one side of the pin from being attached to the bracket, and the positioning baffle contacts the upper end surface of the pin and uses the elasticity of the pin to push it to the position in the first paint stripping gap and / or the second paint stripping gap, so that the part of the pin that needs to be stripped is further guided to be immersed in the paint stripping agent.

[0039] like Figures 3 to 8 In the paint stripping jig shown, the bracket 2 is provided with a bracket second connection end 22, the positioning member 7 is provided with a positioning member connection end 72, and also includes a fastener 6 passing through the bracket second connection end 22 and the positioning member connection end 72, so that the bracket 2 is tightly connected to the positioning member 7. Optionally, in some embodiments, the positioning member and the bracket can be fixed to further improve the stability of the positioning member. Optionally, in other embodiments, the positioning member and the bracket can be connected by riveting, welding, threaded connection, snap-fit, magnetic attraction, etc.

[0040] Optionally, in this embodiment, the positioning member and the bracket are connected by means of screws and threads.

[0041] The housing 4 is provided with a plurality of accommodating cavities at intervals, and the paint stripping gap 5 is formed between two of the accommodating housings 4, and the first paint stripping gap 51 and the second paint stripping gap 52 are arranged opposite to each other. Optionally, in some embodiments, the plurality of accommodating cavities can accommodate a plurality of reactors, and a plurality of reactors or other items that need to be stripped can be placed during the paint stripping process. The first paint stripping gap and the second paint stripping gap are arranged oppositely to each other to adapt to a symmetrically designed reactor, which can provide a more flexible operating space and help to achieve an efficient and continuous paint stripping process.

[0042] The paint stripping station 3 is provided with a station opening 8, and the accommodating chamber 40 is located at the lower side of the station opening 8. Optionally, the setting of the station opening allows the bracket to have more space for placing the reactor, which is convenient for placing the items that need to be stripped into the accommodating chamber. The accommodating chamber extends downward from the side of the station opening, further improving the space utilization rate, so that the paint stripping items with a larger vertical height can be placed in the accommodating chamber, and the pins thereof can be closer to the paint stripping liquid surface, so that the items that need to be stripped can be operated and processed more effectively, which helps to improve work efficiency and reduce operation difficulty.

[0043] like Figures 3 to 8 The paint stripping jig shown also includes a core shielding shell 9 that is arranged to pass through the magnetic core of the reactor 100 and is used to pull up or move down the reactor 100. Optionally, in some embodiments, the core shielding shell can pass through the magnetic cores of multiple reactors, and the operator can pull up or move down multiple reactors at one time without having to operate one by one, thereby further improving the efficiency of the process. Specifically, since the height of the side plate of the first accommodating cavity is greater than the height of the side plate of the second accommodating cavity, more space will be left between the side plate of the first accommodating cavity and the side plate of the second accommodating cavity for the core shielding shell to be placed in, and the core shielding shell can be closer to the bottom of the accommodating cavity, so that the pin can be closer to the paint stripping liquid surface.

[0044] like Figures 1 to 8 In the paint stripping jig shown, the bracket 2 is made of one of stainless steel, titanium alloy and aluminum alloy. Stainless steel has the advantages of high corrosion resistance, high strength and rigidity, can remain stable in harsh working conditions, and can provide support and structural stability, can avoid chemical reaction between the bracket and the paint stripping agent, and further improve the service life of the bracket.

[0045] Aluminum alloy has low density and good strength, while being easy to process and form. This makes it ideal for lightweight brackets. Its corrosion resistance also makes it resistant to corrosion by paint.

[0046] Titanium alloy has high strength and excellent corrosion resistance. It has low density, is relatively light, and can provide excellent mechanical properties. Due to its good corrosion resistance and high temperature stability, titanium alloy can be used as a bracket material, suitable for harsh environmental conditions during paint stripping.
