Description

Technical Field

[0001] This application relates to the technical field of electronic cigarette manufacturing fixtures, and more specifically, it relates to a multifunctional fixture for processing atomizer housings. Background Technology

[0002] As the core atomizing component, the performance and accuracy of the electronic cigarette atomizer directly affect the user experience. The electrode shell in the atomizer is a key structural component, which usually requires precision oil guide grooves or air channels to be machined on its inner wall, while its outer surface is tapped or screwed to achieve reliable electrical connection and mechanical fixation with other components such as the power supply unit and atomization chamber.

[0003] In related technologies, for small, irregularly shaped or multi-faceted electrode shells that need to be machined, traditional split-type clamps or universal vises are commonly used for clamping.

[0004] Regarding the aforementioned technologies, the small size and irregular shape of the electrode shell make it difficult to achieve rapid and accurate positioning using general-purpose fixtures. This results in low positional repeatability of the workpieces in mass production, directly affecting the positional accuracy and consistency of subsequent slot and hole machining. Each workpiece requires individual calibration and locking, which is cumbersome and time-consuming, failing to meet the high-efficiency requirements of modern production lines. The electrode shell typically requires machining on both the inner groove and the outer hole. Traditional clamping methods require disassembling, repositioning, and clamping each workpiece to another fixture or adjusting its posture after machining one side. This process is not only inefficient but also prone to product scrap due to secondary positioning errors. Utility Model Content

[0005] To address the issues in related technologies where using separate fixtures or universal vises to clamp small, irregularly shaped, or multi-faceted electrode shells results in low machining accuracy, poor consistency, and low efficiency, and also makes the products prone to scrapping due to secondary positioning errors, this application provides a multi-functional fixture for machining atomizer shells.

[0006] A multifunctional fixture for processing atomizer housings includes a base plate. Multiple installation stations are evenly arranged along the length of the top surface of the base plate, and a flipping block is provided at each installation station. The flipping block has a first plane and a second plane, which are perpendicular to each other. Slots are provided on both the first and second planes of the flipping block. A matching post is provided at each installation station. Several positioning grooves are evenly arranged along the length of the flipping block. The contours and dimensions of the positioning grooves match the contours and dimensions of the product for positioning the product. A first opening is provided on the side of the positioning groove opposite to the first plane, exposing a first processing surface of the product. A second opening is provided on the side of the positioning groove opposite to the second plane, exposing a second processing surface of the product. A locking assembly is also provided on the flipping block to lock the product into the positioning groove.

[0007] By adopting the above technical solution, multiple mounting stations and flipping blocks are evenly arranged along the length of the base plate, enabling a single fixture to simultaneously position and clamp multiple electrode shells. This significantly improves clamping efficiency during mass production and reduces the time required to process individual workpieces. The flipping block has a first and a second plane that are perpendicular to each other, and each plane is provided with a slot for insertion into the base plate. Combined with the first and second openings on both sides of the positioning groove, after the workpiece is clamped once, by flipping the flipping block and changing the insertion surface, the two sides (such as the inner and outer sides) that need to be processed can be exposed and processed respectively. This avoids the secondary clamping errors and cumbersome operations caused by disassembly and repositioning in traditional methods. The contour and size of the positioning groove match the contour and size of the product, providing a precise and mechanized positioning reference for irregular and small electrode shells. The use of the same design for multiple stations ensures the consistency of positioning of all workpieces in mass production, thereby guaranteeing the positional accuracy and processing precision of subsequent slots, holes, and other processing features. The integration of positioning, flipping, and multiple stations into a single fixture system is ingenious in its structural design, saving the number of fixtures and the space occupied in the production line.

[0008] Preferably, the locking assembly includes a first edge strip, a second edge strip, and connectors. The flipping block has an L-shaped slot between each of the two adjacent positioning slots, which connects the two adjacent positioning slots. The L-shaped slots also allow the first processed surface of the product to protrude from the first opening and the second processed surface of the product to protrude from the second opening. The number of connectors matches the number of L-shaped slots on the flipping block, and the connectors are L-shaped strips. Multiple connectors are evenly arranged along a straight line. One end of the multiple connectors facing the same direction is connected to the first edge strip, and the other end of the multiple connectors facing the same direction is connected to the second edge strip. Each connector corresponds to one of the multiple L-shaped slots, and the connector abuts against the bottom surface of the L-shaped slot. The first edge strip is detachably connected to the flipping block and is used to press against the edge of the first processed surface of the product. The second edge strip is detachably connected to the flipping block and is used to press against the edge of the second processed surface of the product.

[0009] By adopting the above technical solution, an L-shaped connector is used to link the first and second edge pressure strips into one unit, corresponding to the L-shaped slot on the flipping block. The pressure strips act simultaneously on multiple workstations, achieving synchronous and uniform clamping of the edges of the two machined surfaces of a row of workpieces. This simplifies the locking operation and significantly improves the clamping speed. The L-shaped slot design not only connects adjacent positioning slots to accommodate the linkage locking assembly but also ensures that the first and second machined surfaces of the workpiece can fully protrude from the opening, providing operating space for tool processing. The structure of the connector abutting against the bottom surface of the L-shaped slot allows the clamping force to be directly transmitted to the edge of the workpiece through the rigid pressure strip, ensuring a firm lock and effectively resisting the cutting force during processing, thus guaranteeing processing stability.

[0010] Preferably, both the first edge strip and the second edge strip are provided with fitting grooves, and magnets are embedded in the fitting grooves. The flipping block is made of magnetic material, and the magnets are magnetically attracted and fixed to the flipping block.

[0011] By adopting the above technical solution, the first edge strip and the second edge strip are fixed by magnetic attraction. The operator does not need to use tools to tighten multiple screws. He only needs to align the strip in position for it to be automatically attracted and fixed. When disassembling, he only needs to overcome the magnetic force to remove it, which greatly simplifies the loading and unloading steps of the workpiece and further improves production efficiency.

[0012] Preferably, both ends of the base plate are provided with protrusions, a plurality of installation stations are arranged between two of the protrusions, and two adjacent flipping blocks abut against each other.

[0013] By adopting the above technical solution, the protrusions at both ends of the base plate provide end limits and support for multiple side-by-side flipping blocks. Adjacent flipping blocks abut against each other, making the entire workstation array a tight and stable whole on the base plate. This helps to resist vibrations generated during processing and ensures consistent processing accuracy across all workstations. The placement of the two protrusions clearly defines the effective area of ​​the installation station, facilitating operators to quickly and neatly arrange the flipping blocks and preventing misalignment.

[0014] Preferably, the installation station is provided with multiple insertion posts, and the number of slots provided on the first and second planes of the flip block corresponds to the number of insertion posts.

[0015] By adopting the above technical solution, which uses multiple pins and slots in combination, the degrees of freedom of the flipping block can be better restricted compared to single-point positioning, preventing it from undergoing slight rotation or offset around a single axis. This ensures that the flipping block achieves extremely high repeatability in both machining postures, thereby guaranteeing the relative positional accuracy of the workpiece during the two machining operations.

[0016] Preferably, it also includes a mounting plate, wherein the base plate is detachably fixed to the top surface of the mounting plate, and the mounting plate is used to fix it on the processing equipment.

[0017] By adopting the above technical solution, the base plate is fixed to the mounting plate in a detachable manner, and the mounting plate can be specially designed and fixed according to the worktable of different processing equipment. This modular design allows the same multi-functional fixture to be quickly adapted to various machine tools, improving the utilization rate of the fixture and production flexibility.

[0018] Preferably, the top surface of the mounting plate is recessed with at least two pin holes, and the mounting plate is provided with shaft pins that match the size of the pin holes. The number of shaft pins matches the number of pin holes, and the mounting plate is fixed to the base plate by the insertion and engagement of the shaft pins with the pin holes.

[0019] By adopting the above technical solution and using the insertion and connection of the shaft pin and the pin hole, precise positioning and fixing can be achieved when installing the base plate.

[0020] Preferably, the base plate is square, and the top surface of the mounting plate is provided with two L-shaped positioning blocks, which are used to match the two corners of one end of the base plate. By adopting the above technical solution, the two L-shaped positioning blocks provide precise positioning for the two corners of the square base plate, making the placement and initial positioning of the base plate on the mounting plate extremely quick and intuitive, further simplifying the installation operation.

[0021] In summary, the beneficial technical effects of this application are as follows: Multiple mounting stations and flipping blocks are evenly arranged along the length of the base plate, enabling a single fixture to simultaneously position and clamp multiple electrode shells, significantly improving clamping efficiency during mass production and reducing the time required for individual workpiece processing; the flipping block has a first and a second plane perpendicular to each other, and each plane is provided with a slot for insertion into the base plate. Combined with the first and second openings on both sides of the positioning groove, after one clamping, the workpiece can be exposed and processed on its two sides (such as the inner and outer walls) by flipping the flipping block and changing the insertion surface, avoiding the secondary clamping errors and cumbersome operations caused by disassembly and repositioning required in traditional methods; the contour and dimensions of the positioning groove match the contour and dimensions of the product, providing a precise and mechanized positioning reference for irregularly shaped and small electrode shells. The identical design of multiple stations ensures the consistency of positioning for all workpieces in mass production, thereby guaranteeing the positional accuracy and processing precision of subsequent slots, holes, and other processing features; integrating positioning, flipping, and multiple stations into a single fixture system is ingeniously designed, saving on the number of fixtures and the space occupied in the production line.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Reference Figure 1-2 A multi-functional fixture for processing atomizer housings includes a base plate 1, multiple flipping blocks 2, and a locking assembly 3. The base plate 1 serves as the basic support for the entire fixture, and its top surface has multiple mounting stations 11 evenly arranged along the length direction. Each station is equipped with a flipping block 2. Through this multi-station design, multiple electrode housings can be clamped at one time, significantly improving the clamping efficiency of mass production and reducing the time required to process individual workpieces.

[0029] Reference Figure 1-3 The flipping block 2 is the core component of this fixture for multi-functional machining. It has a first plane 21 and a second plane 22 that are perpendicular to each other. Each plane has a slot 23, and each mounting station 11 has a pin 12 that mates with the slot 23, allowing the flipping block 2 to be stably installed on the base plate 1 by plugging it in. This design allows the flipping block 2 to have two switchable mounting postures: when the first plane 21 faces down and is plugged into the pin 12, the second plane 22 faces to the side; conversely, when the second plane 22 faces down, the first plane 21 faces to the side. By changing the plugging surface, the orientation of the workpiece's machining surface can be quickly changed, thus achieving two-sided machining with one clamping, avoiding the secondary positioning errors and cumbersome operations caused by disassembly and reassembly in traditional methods.

[0030] Reference Figure 3 Multiple positioning slots 24 are evenly distributed along the length of the flipping block 2. The contour and size of each positioning slot 24 are precisely designed according to the atomizer electrode shell product to be processed, which can closely fit the shape of the product and provide a precise positioning reference for irregular and small workpieces. All stations adopt the same positioning slot 24 design, which ensures the consistency of positioning of each workpiece in mass production, thereby ensuring the positional accuracy and processing consistency of subsequent processing features such as oil guide grooves and tapping holes.

[0031] Reference Figure 3 To enable machining of both sides of the workpiece, a first opening 25 is provided on the side of the positioning groove 24 opposite to the first plane 21. This allows the first machining surface, such as the inner wall, to be fully exposed after the workpiece is inserted into the positioning groove 24. Similarly, a second opening 26 is provided on the side of the positioning groove 24 opposite to the second plane 22 to expose the second machining surface of the workpiece, such as the outer side. In this way, regardless of the mounting posture of the flipping block 2, there is always a machining surface facing the machining tool, providing ample operating space for machining.

[0032] Reference Figure 1 and Figure 3To reliably lock the product within the positioning slot 24, this fixture is equipped with a high-efficiency locking component 3. This locking component 3 includes a first edge pressure strip 31, a second edge pressure strip 32, and multiple L-shaped connectors 33. On the flipping block 2, an L-shaped slot 27 is provided between every two adjacent positioning slots 24. This slot not only connects adjacent positioning slots 24 but also allows the edges of the first and second machined surfaces of the workpiece to slightly protrude from the corresponding openings after the workpiece is inserted, facilitating the pressure strip's clamping. Multiple L-shaped connectors 33 are evenly arranged along a straight line, with one end connected to the first edge pressure strip 31 and the other end connected to the second edge pressure strip 32, forming an integral frame. During assembly, each connector 33 is embedded into an L-shaped slot 27, with its bottom surface abutting against the bottom surface of the slot. By detachably connecting the first edge pressure strip 31 and the second edge pressure strip 32 to the flipping block 2, the pressure strips can simultaneously clamp the edges of both machined surfaces of an entire row of workpieces. This linkage locking design enables simultaneous and uniform clamping of multiple workpieces, greatly simplifying the operation steps, improving the clamping speed, and directly transmitting the locking force, which can effectively resist the cutting force during the machining process and ensure machining stability.

[0033] Reference Figure 1 To simplify the locking operation, the first edge pressure strip 31 and the second edge pressure strip 32 are preferably fixed to the flipping block 2 by magnetic attraction. The pressure strip has a fitting groove 34, in which a magnet is embedded, while the flipping block 2 is made of a material that can be magnetically attracted. During operation, simply align the pressure strip with the flipping block 2, and it will automatically attract and fix itself; disassembly only requires overcoming the magnetic force to remove it, without the need for tools to tighten screws, thus further improving loading and unloading efficiency. For certain specifically designed electrode housing products, magnets are also pre-embedded on the first and second machined surfaces. To accommodate such products, the number of fitting grooves 34 on the first edge pressure strip 31 and the second edge pressure strip 32 can be further increased to match the position of the magnet in each positioning groove 24. Each fitting groove 34 contains an embedded magnet, so the pressure strip is not only connected to the flipping base by magnetic force, but its magnets can also directly attract the magnets on the product surface, thus achieving double fixation of the product and further enhancing the stability of the workpiece during processing.

[0034] Reference Figure 1-2 To enhance the overall structural stability, protrusions 13 are provided at both ends of the base plate 1. Multiple mounting stations 11 and flipping blocks 2 are confined within the area between two protrusions 13, and adjacent flipping blocks 2 are in close contact with each other. This design allows all flipping blocks 2 to be arranged into a tight whole on the base plate 1, enhancing the rigidity of the entire fixture, helping to resist processing vibrations, ensuring the consistency of processing accuracy at each station, and also facilitating the rapid and neat arrangement of the flipping blocks 2.

[0035] Reference Figure 1-3 To achieve high-precision repeatability of the flip block 2 in two processing postures, multiple insertion posts 12 are provided on each mounting station 11, and the number of slots 23 opened on the first plane 21 and the second plane 22 of the flip block 2 corresponds to this. Compared with single-point positioning, the multi-point insertion method can more effectively restrict the degree of freedom of the flip block 2, prevent it from undergoing slight rotation or displacement during processing, and thus ensure that the relative position of the workpiece has extremely high accuracy in the two processing stages.

[0036] Reference Figure 1 To enhance the versatility and adaptability of the fixture, this multi-functional fixture also includes a mounting plate 4. The base plate 1 is detachably fixed to the top surface of the mounting plate 4, which can be specially designed and installed according to the worktable of different processing equipment. This modular design allows the same fixture to be quickly adapted to various machine tools, improving the utilization rate of the fixture and the flexibility of production scheduling.

[0037] Reference Figure 1 , Figure 2 and Figure 4 To achieve precise positioning and fixation between the base plate 1 and the mounting plate 4, the top surface of the mounting plate 4 is recessed with at least two pin holes 41, and the base plate 1 is equipped with a corresponding number of pivot pins 14. By inserting the pivot pins 14 into the corresponding pin holes 41 of the base plate 1 and the mounting plate 4, precise positioning and reliable connection between the two can be achieved. In addition, the base plate 1 is designed to be square, and the top surface of the mounting plate 4 is provided with two L-shaped positioning blocks 42. These two positioning blocks are used to hold the two corners of one end of the square base plate 1. During installation, simply place the corner of the base plate 1 into the L-shaped positioning block 42 to complete the quick and intuitive initial positioning, and then use the pivot pins 14 to complete the final fixation. The entire installation process is simple and quick.

[0038] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
