Description

Technical Field

[0001] This utility model relates to the field of positioning fixtures, specifically a magnetic positioning fixture assembled with a plastic shell. Background Technology

[0002] The magnetic positioning fixture for assembling plastic housings is a professional tooling fixture that uses magnetic force to achieve precise positioning and stable fixation of plastic housings. It can effectively reduce assembly deviations, significantly improve assembly accuracy, simplify the operation process, and significantly improve production efficiency. It is widely used in plastic housing assembly operations in the electronics, automotive and other fields.

[0003] The existing technology still relies on manual pressing, which is easily affected by the operator's hand strength and pressing angle. This often results in insufficient pressing depth, positional deviation, and other inaccuracies, requiring repeated operations, which leads to a long overall process and seriously restricts work efficiency and operational accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic positioning fixture for plastic housing assembly, which has the advantages of significantly faster response speed, rapid feedback of operation commands, precise control of pressure intensity and position, and greatly improved pressure accuracy, thus solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A magnetic positioning fixture assembled with a plastic shell includes a base plate. The upper end of the base plate has multiple first slots. The lower end of the inner wall of the first slots has multiple second slots. Multiple first connecting blocks are slidably installed on the upper end of the first slots. Limiting tubes are fixedly connected to the lower end of the first connecting blocks. Second connecting blocks are slidably installed on the upper end of the first connecting blocks. A top plate is fixedly connected to the upper end of the second connecting blocks. Pressure applying mechanisms are provided on both sides of the top plate and the upper end of the base plate.

[0006] Preferably, the pressure-applying mechanism includes a third connecting block, a first iron block, a fifth slot, a sixth slot, a second iron block, a coil, and a protective tube; the second connecting block has a third connecting block fixed to both sides of its lower end, and multiple first iron blocks are fixed horizontally to the lower end of the third connecting block; multiple fifth slots are opened through both sides of the upper end of the base plate, and a sixth slot is opened at the lower end of the inner wall of the fifth slot; a second iron block is fixed to the lower end of the inner wall of the fifth slot; a coil is fixed to the side wall of the second iron block; and a protective tube is fixed to the lower end of the second iron block.

[0007] It is worth noting that: through the cooperation of the third connecting block, the first iron block, the fifth slot, the sixth slot, the second iron block, the coil, and the protective tube, the electromagnetic force generated by the coil and the iron block after being energized is used to achieve the pressure application function. The electromagnetic pressure application response is faster, the pressure adjustment is more convenient and precise, and the connection and position of each component are reasonably set, which can ensure the stability and reliability of the pressure application process.

[0008] Preferably, a battery is fixed to one side of the base plate, and the battery is connected to the lower end of the second iron block by wires, with the wires located inside the protective tube.

[0009] It is worth noting that the battery is fixed to one side of the base plate and connected to the second iron block through a wire. The wire is located inside the protective tube. This design makes the power supply line layout neat and avoids the wires being exposed to the outside and being worn or interfered with. The protective tube can effectively protect the wires and ensure the stability and safety of the circuit connection.

[0010] Preferably, the limiting tube is located inside the second slot, and the sidewall of the limiting tube is in contact with the inner wall of the second slot.

[0011] It is worth noting that it can precisely limit the sliding of the first connecting block and the top plate, preventing deviation or shaking during the sliding process and ensuring the overall verticality and stability of the structure.

[0012] Preferably, both ends of the top plate are fixed with limiting plates, and the ends of the two limiting plates that are close to each other are in contact with the two sides of the bottom plate.

[0013] It is worth noting that the limiting plates fixed at both ends of the top plate fit snugly against the sides of the bottom plate, further enhancing the connection stability between the top plate and the bottom plate, limiting the horizontal displacement of the top plate, and preventing the top plate from shifting laterally when subjected to force or sliding.

[0014] Preferably, the fifth and sixth slots are interconnected, the lower end of the protective tube passes through the inner wall of the sixth slot, and the diameter of the fifth slot is larger than the diameter of the sixth slot.

[0015] It is worth noting that: to prevent the second iron block from falling into the sixth slot, the stability of the protective tube inside the sixth slot is increased.

[0016] Preferably, the diameter of the first iron block is smaller than the diameter of the fifth slot, and the multiple first iron blocks correspond one-to-one with the multiple fifth slots.

[0017] It is worth noting that: to ensure the first iron block can be smoothly inserted into the fifth slot, the second iron block will generate magnetism after being energized, thus attracting the first iron block.

[0018] Preferably, a third slot is provided on one side of the second connecting block, and a fourth slot is provided through one end of the second connecting block.

[0019] It is worth noting that it can be easily connected or installed with other external components, and the different positions of the third and fourth slots can adapt to different connection requirements.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Existing structures of this utility model mostly rely on mechanical pressure such as springs and hydraulic pressure. Pressure adjustment requires manual operation, which results in a delayed response and difficulty in precise control. However, this structure adopts electromagnetic pressure, which is driven by the electromagnetic force generated by the energization of the coil. The response speed is faster, and the pressure can be easily controlled by adjusting the current, which greatly improves the accuracy and efficiency of pressure application. 2. Through the fit between the limiting tube and the second slot, and the fit between the top plate limiting plate and the bottom plate, the double limiting in both vertical and horizontal directions effectively prevents deviation during sliding and ensures the stability of the structure during operation.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To address the shortcomings of existing technologies that rely on manual pressing, which is susceptible to variations in operator hand strength and angle, often resulting in insufficient pressing depth or misalignment, and necessitates repeated operations, thus lengthying the process and severely hindering efficiency and accuracy, the following technical solution is proposed. Please refer to [link / reference]. Figure 1-5 ; A magnetic positioning fixture assembled with a plastic shell includes a base plate 1. The upper end of the base plate 1 has multiple first slots 2. The lower end of the inner wall of the first slots 2 has multiple second slots 3. Multiple first connecting blocks 4 are slidably installed on the upper end of the first slots 2. The lower end of the first connecting blocks 4 is fixedly connected to a limiting tube 5. The upper end of the first connecting blocks 4 is slidably installed to a second connecting block 8. The upper end of the second connecting block 8 is fixedly connected to a top plate 6. Pressure applying mechanisms 7 are provided on both sides of the top plate 6 and the upper end of the base plate 1. The limiting tube 5 is located inside the second slots 3. The side wall of the limiting tube 5 is in contact with the inner wall of the second slots 3. Limiting plates are fixedly connected to both ends of the top plate 6. The ends of the two limiting plates that are close to each other are in contact with both sides of the base plate 1. A third slot 9 is opened on one side of the second connecting block 8. A fourth slot 10 is opened through one end of the second connecting block 8.

[0025] The pressure applying mechanism 7 includes a third connecting block 71, a first iron block 72, a fifth slot 73, a sixth slot 74, a second iron block 75, a coil 76, and a protective tube 77. The lower ends of the second connecting block 8 are both fixedly connected to the third connecting block 71. Multiple first iron blocks 72 are horizontally fixedly connected to the lower ends of the third connecting block 71. Multiple fifth slots 73 are formed through the upper ends of the base plate 1 on both sides. A sixth slot 74 is formed at the lower end of the inner wall of each fifth slot 73. A second iron block 75 is fixedly connected to the lower end of the inner wall of each fifth slot 73. A coil 76 is fixed to the side wall of the 5th iron block, a protective tube 77 is fixed to the lower end of the second iron block 75, a battery is fixed to one side of the base plate 1, the battery and the lower end of the second iron block 75 are connected by wires, the wires are located inside the protective tube 77, the fifth slot 73 and the sixth slot 74 are interconnected, the lower end of the protective tube 77 passes through the inner wall of the sixth slot 74, the diameter of the fifth slot 73 is larger than the diameter of the sixth slot 74, the diameter of the first iron block 72 is smaller than the diameter of the fifth slot 73, and multiple first iron blocks 72 correspond one-to-one with multiple fifth slots 73.

[0026] Working principle: The multiple first slots 2 at the upper end provide a sliding mounting base for the first connecting block 4. The limiting tube 5 fixed to the lower end of the first connecting block 4 is located exactly in the second slot 3 that penetrates the lower end of the inner wall of the first slot 2, and the side wall of the limiting tube 5 fits against the inner wall of the second slot 3. This fit can play a precise limiting role when the first connecting block 4 slides, preventing deviation or shaking, and ensuring the verticality and stability of the overall structure. The third slot 9 and the fourth slot 10 that penetrates at one end can be connected or installed with external components as needed to adapt to different connection requirements. The operation of the pressure applying mechanism 7 is the core link. The battery fixed to one side of the base plate 1 is connected to the second iron block 75 through the wire located inside the protective tube 77. The protective tube 77 can protect the wire from wear or interference, ensure stable and safe circuit connection, and provide an independent power supply for pressure application. When pressure is required, the battery powers the coil 76 fixed to the side wall of the second iron block 75. After the coil 76 is energized, it cooperates with the second iron block 75 to generate magnetism. At this time, the multiple first iron blocks 72, which are horizontally arranged below the third connecting block 71 fixed to both sides of the lower end of the second connecting block 8, will be smoothly inserted into the fifth slots 73 that penetrate both sides of the upper end of the base plate 1 because they correspond one-to-one with the multiple fifth slots 73 and their diameters are smaller than the diameters of the fifth slots 73. The magnetism generated by the second iron block 75 will attract the first iron block 72. The fifth slot 73 and the sixth slot 74 at the lower end of the inner wall are interconnected, and the diameter of the fifth slot 73 is larger than the diameter of the sixth slot 74. This can prevent the second iron block 75 from falling into the sixth slot 74 and allow the lower end of the protective tube 77 to pass through the inner wall of the sixth slot 74, increasing the stability of the protective tube 77. As the second iron block 75 attracts the first iron block 72, it will drive the second connecting block 8 to move downward through the third connecting block 71 to achieve the pressure action. Throughout the process, the components ensure rapid pressure response and convenient and accurate pressure adjustment through precise structural cooperation and electromagnetic force transmission, while ensuring the stability and reliability of the overall operation.
