Description

Technical Field

[0001] This utility model relates to the field of multi-stage immersion washing technology for workpieces, specifically a tooling fixture for multi-stage immersion washing operations of workpieces. Background Technology

[0002] In current technologies, the primary function of tooling fixtures is to support workpieces, ensuring their stable suspension on conveyor equipment. Surface treatment is crucial in the workpiece manufacturing process, with multiple immersion washes being key steps in removing impurities, oil, rust, and other contaminants from the workpiece surface, and providing favorable surface conditions for subsequent processes such as electroplating and spraying. Currently, these multiple immersion washes are typically performed using tooling fixtures. However, existing fixtures present several problems in practical use. The stability of the workpiece installation is a significant issue. Due to the fixture's structural design, workpieces may become loose during installation, leading to shaking or even detachment during subsequent immersion washes. This not only affects the immersion quality but can also damage the workpiece and increase production costs.

[0003] However, existing technologies still have shortcomings, such as the following: In existing tooling fixtures, the installation of the fixtures often suffers from insufficient stability. For example, some fixtures may rely solely on simple hooks or slots to secure the fixtures, and if not handled carefully during installation, the fixtures may loosen, causing them to shake or even fall off during subsequent immersion washing operations. Utility Model Content

[0004] The purpose of this invention is to provide a tooling fixture for multi-stage immersion washing of workpieces, so as to solve the problem of insufficient installation stability mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A tooling fixture for multi-stage immersion washing of workpieces includes a transmission structure, a stainless steel frame slidably connected to the inner side of the bottom of the transmission structure, a hanging structure inserted into the inner side of the bottom of the stainless steel frame, the transmission structure including a transmission frame, a guide rail slider installed on the top of the transmission frame, and V-shaped limiting frames installed on the inner sides of the bottom two sides of the transmission frame. The stainless steel frame includes a frame rod, with positioning grooves installed at the bottom of both ends of the frame rod. Inclined toothed blocks are installed at the bottom of the inner side of both ends of the frame rod. An assembly frame is slidably connected to the inner side of the positioning groove. Reverse toothed blocks are installed on both sides of the bottom of the assembly frame. A retractable rod is installed on the top of the assembly frame. A top plate is installed on the top of the retractable rod. A return spring is movably sleeved on the outer wall of the retractable rod.

[0006] Preferably, a T-shaped mounting groove is provided at the bottom of the frame pole, and a positioning magnet is installed on the bottom inner side of the frame pole and on the upper surface of the T-shaped mounting groove.

[0007] Preferably, the hanging frame structure includes a hanging rod, a limit plate is installed at one end of the top of the hanging rod, and two positioning magnets are installed on the left and right sides of the bottom of the limit plate. A reset box is fixedly sleeved on the outer wall of the hanging rod, and a push spring is installed in the inner cavity of the reset box.

[0008] Preferably, a push tube is slidably connected to the outer wall of the boom and the bottom of the push spring, the bottom of the boom is slidably connected to the outer wall of the push tube, and an upper frame is installed on the four sides of the bottom of the push tube.

[0009] Preferably, a rotating rod is rotatably connected to the inner side of one end of the upper frame, a first adjusting frame is rotatably connected to the outer wall of the rotating rod, and a second adjusting frame is rotatably connected to the outer wall of the rotating rod and located on the upper surface of the first adjusting frame.

[0010] Preferably, a lower frame is installed on the outer wall of the boom and on the lower surface of the upper frame, and a support column is installed on the upper surface of the second adjustment frame, with a docking magnet inserted into the inner side of the top of the support column.

[0011] Preferably, the outer wall of the top of the support column is threaded with a threaded cap, and an isolation cover is fixedly connected to the top of the threaded cap.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The stainless steel frame's support rod is inserted into the V-shaped limiting bracket gap of the transmission structure, utilizing its shape to achieve initial limiting and effectively reduce swaying. Next, the assembly frame, through the cooperation of the inverted toothed block and the inclined toothed block, is firmly fixed to the bottom of the support rod under the action of the return spring, further enhancing the stability of the entire fixture. This design makes the installation process of the tooling on the fixture more stable, reducing the risk of tooling swaying or falling due to improper installation. At the same time, the installation of the fixture structure is also very convenient. The limiting plate at the top of the lifting rod is inserted into the T-shaped mounting slot, and the connection between the lifting rod and the support rod is quickly completed by the mutual attraction of the first and second positioning magnets. This magnetic adsorption connection method is not only simple to operate but also provides a firm connection, greatly improving the installation efficiency of the tooling fixture. Compared with traditional fixtures that require complex bolt fixing methods, it saves a lot of time and labor costs, providing a stable and reliable starting condition for multiple immersion operations of the workpiece.

[0013] 2. The No. 1 and No. 2 adjustment frames at one end of the upper and lower frames of the hanger structure can effectively clamp the tooling. By manually raising the upper frame and placing the tooling on the upper surface of the isolation cover, it is released. The adjustment frames, under the action of the push spring, clamp the tooling. Simultaneously, the connecting magnets attract each other through the isolation cover, further enhancing the stability of the clamping. This multi-layered clamping and adsorption structure design ensures that the tooling will not shake or fall off even when subjected to external forces such as water flow impact during immersion washing. Compared to traditional hangers, which may be prone to loosening during immersion washing due to their simple structure, this effectively avoids accidents such as equipment damage or workpiece scrap caused by tooling falling, ensuring the smooth progress of multiple immersion washing operations and improving production efficiency and product quality.

[0016] 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.

[0017] like Figures 1-6 As shown, a tooling fixture for multi-stage immersion washing of workpieces includes a transmission structure 1, with a stainless steel frame 2 slidably connected to the inner side of the bottom of the transmission structure 1, and a mounting bracket structure 3 for mounting. The mounting bracket structure 3 is inserted into the inner side of the bottom of the stainless steel frame 2 for placing the tooling. The transmission structure 1 includes a transmission frame 11, with a guide rail slider 12 installed on the top of the transmission frame 11. The guide rail slider 12 is used to roll on a conventional guide rail. V-shaped limiting brackets 13 are installed on the inner sides of both sides of the bottom of the transmission frame 11 for limiting the bracket rod 21. The stainless steel frame 2 includes a frame rod 21, and positioning grooves 26 are installed at the bottom of the left and right ends of the frame rod 21 to facilitate the assembly frame 23 to limit the frame rod 21. Inclined toothed blocks 22 are installed on the bottom inner side of the left and right ends of the frame rod 21 to facilitate the backing toothed blocks 231 to be locked inside. The assembly frame 23 is slidably connected to the inner side of the positioning groove 26 to limit the position of the frame rod 21 in the gap between the V-shaped limiting frame 13. Backing toothed blocks 231 are installed on both sides of the bottom of the assembly frame 23. When the backing toothed blocks 231 are locked inside the inclined toothed blocks 22, the assembly frame 23 moves outward inside the positioning groove 26. A retraction rod 24 is installed on the top of the assembly frame 23 to limit the return spring 25. A top plate 241 is installed on the top of the retraction rod 24, and the return spring 25 is movably sleeved on the outer wall of the retraction rod 24. The return spring 25 pushes the top plate 241 to insert the backing toothed blocks 231 into the inner side of the inclined toothed blocks 22.

[0018] It should be noted that in this embodiment, when performing the immersion washing operation on the tooling, the stainless steel frame 2 needs to be installed or adjusted first. The frame rod 21 is first inserted into the gap between the V-shaped limiting frames 13. The shape of the frame rod 21 limits the gap between the V-shaped limiting frames 13, reducing the shaking effect. Then, the assembly frame 23 is inserted into the inner side from the positioning groove 26 at the bottom of the left and right ends of the frame rod 21. When the assembly frame 23 is pushed, the backward tooth block 231 is squeezed against the outer wall of the inclined tooth block 22, thereby squeezing the return spring 25. When it stops, the return spring 25 pushes the top plate 241 and the assembly frame 23, thereby causing the backward tooth block 231 to be inserted into the inner side of the inclined tooth block 22, so that the assembly frame 23 is fixed on the inner side of the bottom of the left and right ends of the frame rod 21, limiting the frame rod 21 in the gap between the V-shaped limiting frames 13.

[0019] The bottom of the support rod 21 is provided with a T-shaped mounting groove 27. A first positioning magnet 28 is installed on the bottom inner side of the support rod 21 and on the upper surface of the T-shaped mounting groove 27. The hanging structure 3 includes a hanging rod 31. A limit plate 311 is installed at one end of the top of the hanging rod 31. Second positioning magnets 312 are installed on the left and right sides of the bottom of the limit plate 311. A reset box 32 is fixedly sleeved on the outer wall of the hanging rod 31, and a push spring 33 is installed in the inner cavity of the reset box 32. A push tube 34 is slidably connected to the outer wall of the hanging rod 31 and at the bottom of the push spring 33. The bottom of the hanging rod 31 is slidably connected to the outer wall of the push tube 34. The bottom has four sides with an upper frame 35 installed. A rotating rod 37 is rotatably connected to the inner side of one end of the upper frame 35. A first adjustment frame 38 is rotatably connected to the outer wall of the rotating rod 37. A second adjustment frame 39 is rotatably connected to the outer wall of the rotating rod 37 and the upper surface of the first adjustment frame 38. A lower frame 36 is installed on the outer wall of the hanging rod 31 and the lower surface of the upper frame 35. A support column 391 is installed on the upper surface of the second adjustment frame 39. A mating magnet 393 is inserted into the inner side of the top of the support column 391. A threaded cover 394 is threadedly connected to the outer wall of the top of the support column 391. An isolation cover 392 is fixedly connected to the top of the threaded cover 394.

[0020] It should be noted that in this embodiment, when installing the bracket structure 3, the limiting plate 311 at the top of the hanging rod 31 is inserted into the inner side of the T-shaped mounting groove 27 and enters the inner cavity of the bracket 21. Then, the second positioning magnet 312 at the bottom of the limiting plate 311 is pushed to the upper surface of the first positioning magnet 28. The first positioning magnet 28 and the second positioning magnet 312 attract each other, thereby installing the hanging rod 31 on the lower surface of the bracket 21. This allows for the installation of the tooling. First, the upper frame 35 is manually raised, which drives the push tube 34 to press into the inner cavity of the reset box 32. The tooling is then placed on the upper surface of the isolation cover 392. Next, the upper frame 35 is released, and the first adjustment frame 38 or the second adjustment frame 39 at the bottom of the upper frame 35 presses down on the first adjustment frame 38 and the second adjustment frame 39 on one end of the lower frame 36, thus clamping the tooling. The mating magnets 393 on the inner top of the first adjustment frame 38 and the second adjustment frame 39 attract each other through the isolation cover 392, reducing the chance of the tooling shaking or falling during the immersion operation. After the tooling is placed, it is transported to the immersion operation area via the guide rail slider 12.

[0021] The working principle of this utility model is as follows: When immersing the tooling, it is necessary to first install or adjust the stainless steel frame 2. First, insert the frame rod 21 into the gap between the V-shaped limit frame 13. The shape of the frame rod 21 is used to limit the gap between the V-shaped limit frame 13, thereby reducing the shaking effect. Then, when installing the bracket structure 3, the limiting plate 311 at the top of the rod 31 is inserted into the inner side of the T-shaped mounting groove 27 and enters the inner cavity of the rod 21. Then, the second positioning magnet 312 at the bottom of the limiting plate 311 is pushed to the upper surface of the first positioning magnet 28. The first positioning magnet 28 and the second positioning magnet 312 attract each other, thereby installing the rod 31 on the lower surface of the rod 21. This allows for the installation of the tooling. First, the upper frame 35 is manually raised, which drives the push tube 34 to press into the inner cavity of the reset box 32. The tooling is then placed on the upper surface of the isolation cover 392. Next, the upper frame 35 is released, and the first adjustment frame 38 or the second adjustment frame 39 at the bottom of the upper frame 35 press down on the first adjustment frame 38 and the second adjustment frame 39 on the upper surface of one end of the lower frame 36, thus clamping the tooling through the first adjustment frame 38 and the second adjustment frame 39 at one end of the upper frame 35 and the lower frame 36. Furthermore, the mating magnets 393 on the inner side of the top of the first adjustment frame 38 and the second adjustment frame 39 attract each other through the isolation cover 392, thereby reducing the chance of the tooling shaking or falling during the immersion operation. After the tooling is placed, it is transported to the immersion operation area via the guide rail slider 12.
