Description

Technical Field

[0001] This invention relates to the field of water-cooled plate manufacturing technology, and in particular to an automatic riveting device for water-cooled plate nozzles. Background Technology

[0002] In mass production of brazing, it is usually necessary to pre-fix the workpiece before brazing. The main purpose of pre-fixation is to establish and maintain a stable and precise mechanical environment under high-temperature brazing conditions, ensuring that the brazing filler metal can flow along the expected path and form a reliable joint, while also ensuring product consistency. If pre-fixation fails, common consequences include quality problems such as misaligned faucets, weld leaks, or incomplete welds.

[0003] Currently, the main methods for pre-fixing water-cooled plates and water taps before brazing are as follows: (a) Mechanical clamping method. Special tooling or quick clamps consisting of a base plate, pressure plate, pressure block and bolts are used to provide stable pressure from above and the side. This method provides uniform pressure and is suitable for mass production. However, due to the addition of more mechanical structures, it will significantly increase heat absorption during the brazing process, which can easily lead to welding failure at the brazing site.

[0004] (ii) Design-assisted method. This involves designing matching grooves, protrusions, or threaded structures on the faucet and the plate to achieve pre-tightening, or designing the faucet to be slightly larger than the mounting hole size, creating an interference fit through pressing or thermal expansion and contraction. This method offers precise positioning but heavily relies on structural provisions made during the product design phase, making it unsuitable for products without such design.

[0005] (iii) Temporary spot welding method. This method uses self-fusion welding, argon arc welding, or resistance spot welding to create tiny weld points on the workpiece edge for secure fixation. This method is reliable and requires no external tooling. However, for thin-walled water-cooled plates (only about 1 mm thick), this method carries the risk of burn-through, and laser spot welding may also cause thermal damage to the workpiece.

[0006] (iv) Auxiliary fixing method. Thin metal sheets are bent and clipped to the edge of the part, or temporary fixing is achieved by using the adhesiveness of flux paste or temporary adhesive. This type of method is simple and flexible in structure, but its applicability is limited for thin-walled products and for the environmental protection requirements of some customers.

[0007] Currently, the pre-fixation of water nozzles on water-cooled plates mainly adopts two processes: laser pre-fixation and riveting pre-fixation. With the increasing prominence of the risk of thermal damage from laser spot welding, the application of riveting pre-fixation technology is becoming more and more widespread.

[0008] However, in actual production, this product uses a structure where irregularly shaped water nozzles are connected to cold-rolled plates—the cold-rolled plates have mounting holes corresponding to the irregularly shaped water nozzles, which are then inserted into these holes before welding. Because the riveting area of ​​the irregularly shaped water nozzle is almost flush with the surface of the water-cooled plate after installation, the exposed portion of the structure available for the riveting tools is extremely limited due to actual dimensional tolerances and flatness limitations. This easily leads to incomplete riveting and weld defects. Furthermore, if a direct clamping method is used, the flux sprayed on the surface of the cold-rolled plate will fall off, and if the clamping position is set in the central area, it will interfere with the operating path of the riveting drill bit. In addition, different specifications of water nozzles vary in size, and existing pre-fixing devices are difficult to flexibly adapt to various specifications, resulting in poor versatility.

[0009] In summary, the existing technology for riveting water-cooled plate nozzles has problems such as difficulty in riveting positioning, incomplete riveting, and poor adaptability to different nozzle specifications. Summary of the Invention

[0036] like Figures 1 to 7 As shown in the figure, an automatic riveting device for water-cooled plate nozzles provided in this embodiment of the invention includes a supporting base plate 1, a cold plate placement plate 2, a lifting disc 3, a lifting mechanism 4, and a pressing pneumatic tooling 5. The cold plate placement plate 2 is located on the top of the supporting base plate 1 and is used to place the cold plate 7. The cold plate placement plate 2 has a placement groove 201. The lifting disc 3 is located in the placement groove 201 and is used to support the water nozzle 8. The lifting mechanism 4 is connected to the lifting disc 3 and is used to drive the lifting disc 3 to rise and fall to adjust the support height of the water nozzle 8; The pneumatic clamping fixture 5 is located at the bottom edge of the supporting base plate 1 and is used to clamp the cold plate 7 during riveting.

[0037] Specifically, the base plate 1 serves as the installation foundation for the entire device, with its top used to install the cold plate placement plate 2 and its bottom edge used to install the clamping pneumatic tooling 5.

[0038] The cold plate placement plate 2 is set on top of the supporting base plate 1 and is used to place the cold plate 7 to be processed. The cold plate placement plate 2 has a placement groove 201, and the position of the placement groove 201 corresponds to the position of the water nozzle 8 to be installed on the cold plate 7.

[0039] A lifting disc 3 is disposed within the placement groove 201 to support the water nozzle 8. The upper surface of the lifting disc 3 is shaped to fit the bottom of the water nozzle 8 to provide stable support.

[0040] The lifting mechanism 4 is connected to the lifting disc 3 and is used to drive the lifting disc 3 to rise and fall to adjust the support height of the water nozzle 8. Through the adjustment of the lifting mechanism 4, water nozzles 8 of different specifications can be placed at a suitable working height, thus giving the device good versatility.

[0041] A pneumatic clamping fixture 5 is located at the bottom edge of the supporting base plate 1 and is used to clamp the cold plate 7 during riveting. The clamping area of ​​the pneumatic clamping fixture 5 is located around the contact area between the cold plate 7 and the water nozzle 8, and avoids the welding area to avoid affecting the subsequent welding quality.

[0042] The working principle of this application embodiment is as follows: The base plate 1 serves as the installation foundation for the device, providing stable support for all components. A cold plate placement plate 2 is positioned on top of the base plate 1, with a placement groove 201 on it to accommodate the water nozzle 8. Positioning components ensure accurate placement of the cold plate 7. A lifting disc 3 is located within the placement groove 201 and can move up and down via a lifting mechanism 4, thereby adjusting its support height according to the specifications of the water nozzle 8, ensuring that water nozzles of different sizes are in suitable working positions. A pneumatic clamping fixture 5 is positioned at the bottom edge of the base plate 1, applying clamping force to the cold plate 7 during riveting. The clamping area is located around the contact area between the cold plate 7 and the water nozzle 8, avoiding the welding area, thus ensuring the stability of the cold plate 7 during riveting and preventing adverse effects on the welding area from the clamping action. After the cold plate 7 is clamped and the water nozzle 8 is fixed, the riveting drill bit performs the riveting tensioning operation on the water nozzle 8.

[0043] Overall, this technical solution achieves adaptive support and fixation for water nozzles 8 of different specifications through the setting of lifting disc 3 and lifting mechanism 4, and achieves reliable clamping of cold plate 7 around the riveting area through pressing pneumatic tooling 5, thereby effectively solving the problems of difficult riveting positioning, incomplete riveting and poor adaptability to water nozzles of different specifications.

[0044] In some embodiments of the present invention, the automatic riveting device for the water-cooled plate nozzle further includes a riveting drill bit device for riveting and tightening the nozzle 8. Specifically, the riveting drill bit device can be a conventional riveting tool in the art, the specific structure and working principle of which are well known to those skilled in the art and will not be described in detail here.

[0045] like Figure 1 As shown, in some embodiments of the present invention, the cold plate placement plate 2 is provided with a positioning member, which is used to position the cold plate 7.

[0046] Specifically, the positioning components can be implemented in the form of positioning pins, positioning blocks, or positioning posts, which are set on the upper surface of the cold plate placement plate 2 and cooperate with the pre-set positioning holes or positioning edges on the cold plate 7. The number of positioning components can be set according to actual positioning requirements, for example, two or four positioning components can be set to achieve precise positioning of the cold plate 7. By setting positioning components to position the cold plate 7, the consistency of the riveting position of each water nozzle 8 can be ensured.

[0047] like Figure 1 As shown, in some embodiments of the present invention, the cold plate placement plate 2 is further provided with a product removal slot 202.

[0048] Specifically, the product removal slot 202 is located at the edge of the cold plate placement plate 2. Its shape can be an arc-shaped notch or a rectangular groove, preferably a rectangular groove, which makes it easy for operators to remove the product from the cold plate placement plate 2 after riveting.

[0049] The product removal slot 202 is designed to facilitate the quick removal of products by operators or automated material handling devices after riveting, thereby improving production efficiency and preventing scratches on the surface of the cold plate 7 during the material handling process.

[0050] like Figures 1 to 3 As shown, in some embodiments of the present invention, the automatic riveting device for water-cooled plate nozzles further includes a micro airbag 6, which is disposed in the center of the lifting disc 3. The inflated shape of the micro airbag 6 is adapted to the internal area of ​​the water nozzle 8 so as to fix the water nozzle 8 in the placement groove 201 by expansion and compression.

[0051] Specifically, the micro airbag 6 can be made of a flexible, expandable material, such as rubber or silicone. The micro airbag 6 is connected to an external inflation device via an air passage, which can be a manual air pump or an automatic air source control system. When the micro airbag 6 is not inflated, it is in a contracted state, and the water nozzle 8 can be easily fitted onto the outside of the micro airbag 6; when the micro airbag 6 is inflated, its volume expands and fills the internal space of the water nozzle 8, fixing the water nozzle 8 in the placement groove 201 through expansion and compression.

[0052] In detail, the aperture and shape of the internal space of the water nozzle 8 may vary for different specifications. By controlling the inflation pressure of the micro-airbag 6, the micro-airbag 6 can adaptively fill the internal space of water nozzles 8 of different sizes, thereby achieving universal fixation. This expansion and compression fixing method differs from traditional mechanical clamping. It uses the uniform expansion force of the flexible airbag to apply uniform force to the inner wall of the water nozzle 8, avoiding the local stress concentration and water nozzle deformation problems that may be caused by rigid clamping, while ensuring that the water nozzle 8 does not rotate or move axially during the riveting process.

[0053] like Figure 1 As shown, in some embodiments of the present invention, the clamping pneumatic tooling 5 includes a cylinder 501, a connector 502 disposed at the output end of the cylinder 501, and a clamping member 503 disposed on the connector 502. The clamping member 503 includes a clamping head adapter 504 and a plurality of clamping heads 505 disposed on the clamping head adapter 504. On the end face of the clamping head 505 away from the connector 502, a plurality of arc-shaped clamping plates 506 are evenly distributed along its circumference, and there is a gap between two adjacent arc-shaped clamping plates 506.

[0054] Specifically, cylinder 501 is fixedly installed on the top edge of the supporting base plate 1, and its output end extends upward and connects to connector 502. One end of connector 502 is connected to the piston rod of cylinder 501, and the other end is connected to pressure head adapter 504. Several pressure heads 505 are installed on pressure head adapter 504, and the number of pressure heads 505 can be set according to the number and distribution position of water nozzles 8 on cold plate 7. The end face of pressure head 505 away from connector 502 is the pressure working surface. Several arc-shaped pressure plates 506 are evenly distributed along the circumferential direction on this end face. There is a gap between two adjacent arc-shaped pressure plates 506, forming a pressure structure similar to petals or claws.

[0055] like Figure 1 As shown, in some embodiments of the present invention, two clamping heads 505 are provided, and the two clamping heads 505 are arranged opposite to each other; the clamping head adapter 504 includes a middle connecting post and a bottom connecting plate, one end of the middle connecting post is connected to the connector 502, and the other end is connected to the bottom connecting plate; the two ends of the bottom connecting plate are respectively connected to the two clamping heads 505.

[0056] Specifically, the two clamping heads 505 are symmetrically arranged with respect to the central axis of the clamping head adapter 504. The intermediate connecting post is vertically arranged, with its top end fixedly connected to the connector 502 and its bottom end fixedly connected to the middle of the bottom connecting plate. The bottom connecting plate is a longitudinally extending plate-like structure, with a clamping head 505 fixedly installed at each end. The positions of the two clamping heads 505 correspond to the riveting positions of the two water nozzles 8 on the cold plate 7.

[0057] In detail, this dual-pressure head design, driven by the same cylinder 501, ensures the synchronization of the pressure action of the two pressure heads 505, guaranteeing that the pressure state of the two water nozzles 8 is consistent. Meanwhile, the inverted T-shaped structure formed by the bottom connecting plate and the middle connecting column effectively reduces the overall weight of the pressure component 503 while ensuring sufficient structural strength, which is beneficial for the rapid response of the cylinder 501 and reduces energy consumption.

[0058] like Figure 6 As shown, in some embodiments of the present invention, the pressure head adapter 504 may also be cylindrical, and the pressure head 505 may be four in number, with the four pressure heads 505 distributed at intervals along the outer circumferential surface of the pressure head adapter 504.

[0059] Specifically, the pressure head adapter 504 has a cylindrical structure, and four pressure heads 505 are evenly distributed along the outer circumference of the pressure head adapter 504. The included angle between two adjacent pressure heads 505 is independently selected from 30-120°. Each pressure head 505 corresponds to the riveting position of a water nozzle 8 on the cold plate 7.

[0060] In detail, this circumferentially distributed design of four clamping heads 505 is suitable for clamping operations on cold plates 7 with 1-4 water nozzles 8. In this embodiment, a cylinder 501 drives the clamping head adapter 504, thereby causing the four clamping heads 505 to move simultaneously, simplifying the device structure, reducing manufacturing costs, and ensuring the clamping synchronization of the four clamping heads 505.

[0061] like Figure 6 As shown, in some embodiments of the present invention, a first driving mechanism 507 is provided between the pressure head adapter 504 and the pressure head 505. The first driving mechanism 507 is used to drive the pressure head 505 to move along the radial direction of the pressure head adapter 504 to adjust the pressure position.

[0062] Specifically, the first drive mechanism 507 can be a miniature cylinder. The first drive mechanism 507 is located outside the pressure head adapter 504, and its output end is connected to the pressure head 505. Driven by the first drive mechanism 507, the pressure head 505 can move outward or inward along the radial direction of the pressure head adapter 504, thereby adjusting the position of the pressure head 505 on the horizontal plane.

[0063] like Figures 1 to 7 As shown, in some embodiments of the present invention, the lifting mechanism 4 includes a connecting piece 401 and a second driving mechanism 402 for driving the connecting piece 401 to rise and fall, and the side of the connecting piece 401 away from the second driving mechanism 402 is connected to the lifting disc 3. The cold plate placement plate 2 has a lifting groove that cooperates with the lifting mechanism 4, and the lifting groove is connected to the placement groove 201.

[0064] Specifically, the connecting piece 401 is a sheet-like connecting component, one end of which is fixedly connected to the output end of the second drive mechanism 402, and the other end is fixedly connected to the edge or bottom of the lifting disc 3. A lifting groove is formed on the cold plate placement plate 2, extending vertically and communicating with the placement groove 201. The lifting mechanism 4 is accommodated within the lifting groove, and the connecting piece 401 can move vertically up and down within the lifting groove.

[0065] In detail, the second drive mechanism 402 drives the connecting piece 401 to rise and fall within the lifting groove, which in turn drives the lifting disc 3 to rise and fall within the placement groove 201. By setting the lifting groove to guide and limit the rising and falling movement of the connecting piece 401, the linearity and stability of the rising and falling movement of the lifting disc 3 are ensured, preventing the lifting disc 3 from tilting or swaying during the rising and falling process, thereby ensuring that the water nozzle 8 always maintains an accurate posture during the rising and falling process.

[0066] In some embodiments of the present invention, the second drive mechanism 402 is a miniature cylinder.

[0067] Specifically, the miniature cylinder is selected from cylinders with small diameter and stroke, with the diameter generally ranging from 10mm to 32mm and the stroke generally ranging from 5mm to 50mm. The miniature cylinder can be installed in the lifting slot on the cold plate placement plate 2, and its piston rod is connected to the lifting disc 3 through the connecting piece 401.

[0068] The use of miniature cylinders, which are small in size and light in weight, facilitates a compact layout of the device; the miniature cylinders have a fast response speed and can quickly adjust the height of the lifting disc 3, improving work efficiency.

[0069] like Figures 4 to 5 As shown, in some embodiments of the present invention, the second drive mechanism 402 includes a first sleeve 403, a second sleeve 404 and a drive assembly 405, wherein the first sleeve 403 is sleeved outside the second sleeve 404 and the drive assembly 405 is disposed inside the first sleeve 403. The drive assembly 405 includes a first rotating shaft 406, a second rotating shaft 407, a first bevel gear 408, and a second bevel gear 409, wherein the first bevel gear 408 is sleeved on the first rotating shaft 406, and the second bevel gear 409 is sleeved on the second rotating shaft 407, and the first bevel gear 408 and the second bevel gear 409 cooperate with each other. The first rotating shaft 406 is rotatably disposed inside the first sleeve 403, and the axis of the first rotating shaft 406 is perpendicular to the length direction of the first sleeve 403. The end of the first rotating shaft 406 extends out of the first sleeve 403 and is connected to a rotating rod 410. The first sleeve 403 is provided with a first partition 411, and the second rotating shaft 407 rotatably passes through the first partition 411. The end of the second rotating shaft 407 extending out of the first partition 411 is provided with a lead screw 412. The second sleeve 404 is provided with a second partition 413, and the second partition 413 is provided with a threaded hole that cooperates with the lead screw 412.

[0070] Specifically, the second drive mechanism 402 adopts a manually adjustable screw lifting structure. The first sleeve 403 is fixedly installed in the lifting groove and is hollow inside. The second sleeve 404 is located inside the first sleeve 403 and can slide along the length of the first sleeve 403. More specifically, both the first sleeve 403 and the second sleeve 404 are cuboid in shape.

[0071] A drive assembly 405 is installed inside the first sleeve 403 and is used to drive the second sleeve 404 to move up and down relative to the first sleeve 403. More specifically, a first rotating shaft 406 is horizontally arranged inside the first sleeve 403, with one end extending through the side wall of the first sleeve 403 and connected to a rotating rod 410. A first bevel gear 408 is fixedly sleeved on the first rotating shaft 406. A second rotating shaft 407 is vertically arranged, with its upper outer end rotatably mounted on a first partition plate 411. A lead screw 412 is also provided at the upper end of the second rotating shaft 407. A second bevel gear 409 is fixedly sleeved on the second rotating shaft 407 and meshes with the first bevel gear 408. A second partition plate 413 is provided inside the second sleeve 404, and the threaded hole on the second partition plate 413 is threadedly engaged with the lead screw 412. A connecting piece 401 is fixedly connected to the upper end of the second sleeve 404.

[0072] In detail, when the operator rotates the rotating rod 410, the first rotating shaft 406 drives the first bevel gear 408 to rotate. The first bevel gear 408, through meshing, drives the second bevel gear 409 and the second rotating shaft 407 to rotate. The second rotating shaft 407 drives the lead screw 412 to rotate. Since the lead screw 412 is threadedly engaged with the threaded hole on the second partition plate 413, and the second sleeve 404 is circumferentially confined within the first sleeve 403 (based on the fact that both the first sleeve 403 and the second sleeve 404 are cuboid in shape), the rotational motion of the lead screw 412 is converted into the linear lifting motion of the second sleeve 404 along the axial direction. The second sleeve 404 then drives the lifting disc 3 to rise and fall through the connecting piece 401.

[0073] This manually adjustable lifting mechanism is simple in structure and low in cost, and can adjust the height of the lifting disc 3 without the need for an air source. Simultaneously, the cooperation of the first bevel gear 408 and the second bevel gear 409 converts horizontal input into vertical lifting output, making operation convenient and space-saving. Furthermore, this screw-nut combination has a self-locking function; when the rotating rod 410 stops rotating, the lifting disc 3 remains in its current position.

[0074] In some embodiments of the present invention, multiple riveting drill bit devices are provided, each riveting drill bit device is independently controlled, and is used to rivet multiple water nozzles 8 synchronously or sequentially.

[0075] Specifically, the number of riveting drill bits corresponds to the number of water nozzles 8 on the cold plate 7. Each riveting drill bit is driven by an independent drive mechanism (such as an independent rotary motor and feed cylinder), which can achieve synchronous riveting or sequential riveting according to a preset order.

[0076] In detail, for a cold plate 7 with multiple water nozzles 8, multiple riveting drill bits can be used to rivet multiple water nozzles 8 simultaneously, which significantly improves production efficiency.

[0077] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
