Precise positioning and fixation ensure the accuracy and consistency of dispensing, which is essential for product quality and performance. Existing tooling fixtures are often designed for specific parts, lacking versatility and adaptability, leading to low testing efficiency and increased costs. Therefore, developing a tooling fixture that can adapt to various testing objects has significant practical application value. Utility Model Content
[0004] In view of the problems in the related technologies, this utility model proposes a multifunctional tooling fixture to overcome the above-mentioned technical problems existing in the existing related technologies.
[0005] Therefore, the specific technical solution adopted by this utility model is as follows:
[0006] A multifunctional tooling fixture includes a base, a fixing block on the top of the base, a plurality of fixing blocks, a positioning mechanism between the fixing blocks and the base, and a fine-tuning mechanism on the fixing blocks.
[0007] Furthermore, in order to clamp different types of parts and enhance the versatility of this fixture, the fine-tuning mechanism includes a mounting groove on one side of the fixed block. The mounting groove is connected to a rotating shaft via a bearing. A driven gear is fixedly connected to the rotating shaft. One end of the rotating shaft passes through the mounting groove and is connected to the driving gear. The driven gear meshes with a toothed plate. One end of the toothed plate passes through the fixed block and is connected to a moving plate. A step is provided on the moving plate, and a limiting mechanism is provided above the driving gear.
[0008] Furthermore, to ensure the stability of the moving plate after adjustment, the limiting mechanism includes a fixed plate located above the drive gear, a moving rod that runs through the inside of the fixed plate, a locking block that is fixedly connected below the moving rod, the locking block matching the drive gear, and a spring sleeved on the outside of the moving rod.
[0009] Furthermore, one end of the spring is fixedly connected to the fixed plate, and the other end is fixedly connected to the locking block.
[0010] Furthermore, in order to ensure the stability of the moving plate and prevent it from shifting during movement, a slider is provided below the moving plate, and a groove is provided on the fixed block, with the slider matching the groove.
[0011] Furthermore, in order to fix the fixing block in place and prevent the clamp from moving when holding the PCBA board, thus affecting the fixing effect of the PCBA board, the positioning mechanism includes a connecting plate on one side of the fixing block. The connecting plate has a through hole with a bolt inside the through hole, and the base has a threaded hole with the bolt matching the threaded hole.
[0012] Furthermore, the fixing plate is connected to the mounting groove, and the mounting groove is connected to the fixing block.
[0013] The beneficial effects of this utility model are as follows:
[0014] (1) By setting up a fine-tuning mechanism and a positioning mechanism, the connecting block can be fixed inside different threaded holes, allowing users to flexibly adjust the position of the connecting block according to specific needs. This enables the fixing of the block, thus adapting to parts of different sizes and shapes. The fine-tuning mechanism provides precise adjustment capabilities, ensuring the moving plate can be accurately positioned in the required location. The rotation of the drive gear drives the toothed plate to move, and the movement of the toothed plate drives the moving plate to move along a predetermined track. This design is not only simple and reliable but also provides sufficient clamping force to ensure the stability of the parts during dispensing operations. The stepped structure on the moving plate can well adapt to parts of different heights, further enhancing the versatility of the fixture.
[0015] (2) By setting a limit mechanism, the rotation of the drive gear can be effectively controlled, thereby ensuring the fixing effect of the tooling fixture on the parts. The drive gear is firmly fixed when the block and the slot are fully engaged, preventing any rotation. This design ensures that the moving plate remains stable when fixing the parts and will not move due to the accidental rotation of the drive gear, thus affecting the fixing effect on the parts.

[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] According to an embodiment of the present invention, a multifunctional tooling fixture is provided.
[0025] Example 1
[0026] like Figures 1-4As shown, the multifunctional tooling fixture according to an embodiment of this utility model includes a base 1, with fixing blocks 2 provided above the base 1. The number of fixing blocks 2 is multiple, and more than four are required. In this application, there are five fixing blocks 2. By setting five fixing blocks 2, when fixing larger parts, the fifth fixing block 2 can be used to fix the part at the corner, ensuring the stability of the part and reducing shaking. A positioning mechanism 3 is provided between the fixing blocks 2 and the base 1, and a fine-tuning mechanism 4 is provided on the fixing blocks 2. Structure 4 includes a mounting groove 401 located on one side of the fixed block 2. A rotating shaft 402 is connected to the mounting groove 401 via a bearing. A driven gear 403 is fixedly connected to the rotating shaft 402. One end of the rotating shaft 402 passes through the mounting groove 401 and connects to a driving gear 404. The driven gear 403 meshes with a gear plate 405. One end of the gear plate 405 passes through the fixed block 2 and connects to a moving plate 406. A step 407 is provided on the moving plate 406. A limiting mechanism 5 is provided above the driving gear 404. The limiting mechanism 5 includes components located above the driving gear 404. A fixed plate 501 has a moving rod 502 connected through it. A locking block 503 is fixedly connected below the moving rod 502, and the locking block 503 matches the drive gear 404. A spring 504 is sleeved on the outside of the moving rod 502. One end of the spring 504 is fixedly connected to the fixed plate 501, and the other end is fixedly connected to the locking block 503. By setting the spring 504, the stability of the locking block 503 can be ensured, thereby ensuring the limiting effect on the drive gear 404. A slider 6 is provided below the moving plate 406, and a fixed block 2 is provided with... The slide groove 7 and the slider 6 are matched with the slide groove 7. By setting the slider 6 and the slide groove 7, the stability of the movement of the moving plate 406 can be guaranteed and the moving plate 406 can be prevented from deviating during the movement. The positioning mechanism 3 includes a connecting plate 301 located on one side of the fixed block 2. The connecting plate 301 is provided with a through hole 302. A bolt 303 is provided inside the through hole 302. The base 1 is provided with a threaded hole 304. The bolt 303 is matched with the threaded hole 304. The fixed plate 501 is connected to the mounting groove 401 and the mounting groove 401 is connected to the fixed block 2.
[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0028] In practical applications, when clamping parts is required, the bolt 303 is connected to the threaded hole 304 through the through hole 302, allowing the user to flexibly adjust the position of the connecting block according to specific needs, thus adapting to parts of different sizes and shapes. After the connecting block is fixed, the fixing block 2 can remain stable. Then, by pulling the moving rod 502 upward, the locking block 503 is moved away from the driving gear 404, which rotates the driving gear 404, causing the rotating shaft 402 to rotate. The rotating shaft 402 rotates the driven gear 403, which in turn moves the toothed plate 405. The movement of the toothed plate 405 moves the moving plate 406, which precisely positions the moving plate 406 in the required position, providing sufficient clamping force for the part and keeping it stable during the dispensing operation. Through this unique mechanical structure, the tooling fixture can effectively fix different parts, whether standard or non-standard, a suitable fixing method can be found. This not only improved production efficiency but also significantly reduced production costs.
[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, and by setting the fine-tuning mechanism 4 and the positioning mechanism 3, the connecting block can be fixed inside different threaded holes 304, allowing users to flexibly adjust the position of the connecting block according to specific needs. This enables the fixing of the fixing block 2, thus adapting to parts of different sizes and shapes. The fine-tuning mechanism 4 provides precise adjustment capabilities, ensuring that the moving plate 406 can be accurately positioned in the required location. The rotation of the drive gear 404 drives the toothed plate 405 to move, and the movement of the toothed plate 405 drives the moving plate 406 to move along a predetermined track. This design is not only simple and reliable but also provides sufficient clamping force to ensure the stability of the parts during the dispensing operation. The step 407 structure on the movable plate 406 can adapt well to parts of different heights, further enhancing the versatility of the fixture. By setting the limiting mechanism 5, the rotation of the drive gear 404 can be effectively controlled, thereby ensuring the fixture's fixation effect on the parts. The locking block 503 engages with the slot on the drive gear 404. When the locking block 503 and the slot are fully engaged, the drive gear 404 will be firmly fixed, preventing any rotation. This design ensures that the movable plate 406 remains stable when fixing parts and will not move due to accidental rotation of the drive gear 404, thus affecting the fixation effect on the parts.
