Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding processing, in particular to a welding device for integrated tray cold plate production. BACKGROUND

[0002] Tray cold plate, also commonly known as cold water plate, is a component that plays a key role in heat dissipation in industrial production and equipment operation. It is usually made of metal materials such as aluminum alloy, copper alloy, etc. These materials have excellent thermal conductivity and can quickly conduct and dissipate heat from the heat source, ensuring that the equipment runs stably in a suitable temperature environment.

[0003] With the continuous development of industrial technology, the performance requirements of tray cold plates are also increasing. In the manufacturing process of tray cold plates, welding is one of the key links, which directly affects the overall performance and quality of the cold plate.

[0004] Friction welding, as an advanced solid-phase welding technology, has unique advantages. It uses the heat generated by friction to make the welding site plastic, and then connects it under the action of upset force. The whole process does not need to add filler material, and the heat affected zone is small, which can effectively avoid the deformation problem caused by traditional welding methods.

Obviously, the described embodiments are some but not all of the embodiments of the present application.

The terms "vertical", "horizontal", "left", "right" and the like used herein are only for illustrative purposes.

[0024] As shown in Figures 1 to 7 The present application is a kind of integrated tray cold plate production welding device, comprising; truss 1, conveying table 2, machining table 3, the handling mechanism 4 of tray cold plate on conveying table 2 is handled to machining table 3, the welding mechanism 5 of tray cold plate welding; The handling mechanism 4 comprises: screw rod 41 fixedly installed on the truss 1, mounting plate 42 screw connected to the screw rod 41, clamping plate 43 slidingly installed on the mounting plate 42, driving assembly driving clamping plate 43 to slide horizontally, motor one 45 driving screw rod 41 to rotate, air cylinder 46 fixedly installed on the clamping plate 43, push block 47 fixedly connected with the piston rod of air cylinder 46, clamping block 48 rotatingly installed on the push block 47, the clamping block 48 is symmetrically provided with two groups; The driving assembly comprises: motor two 441 fixedly installed on the mounting plate 42, rotatingly installed on the mounting plate 42 rotating wheel 442;The output shaft of motor two 441 is provided with conveying belt 443 on rotating wheel 442, and clamping plate 43 is fixedly installed on the conveying belt 443.

[0025] When the welding operation needs to be performed on the cold plate tray, the operator only needs to accurately place the tray cold plate to be processed at the specified position of the conveying table 2, and then the conveying table 2 starts to stably convey the tray cold plate towards the processing table 3. Subsequently, the driving motor one 45 starts to drive the screw rod 41 to rotate, and the mounting plate 42 moves upward along the axis direction of the screw rod 41 under the threaded transmission of the screw rod 41. At the same time, the driving motor two 441 starts to operate to drive the conveying belt 443 to rotate, thereby driving the clamping plate 43 to move along the horizontal direction of the mounting plate 42, so that the clamping plate 43 can be accurately conveyed to the area directly above the conveying frame.

[0026] After the conveying frame conveys the tray cold plate to the pre-set specified processing area, the clamping plate 43 gradually approaches the tray cold plate to be processed under the cooperative driving action of the motor one 45 and the motor two 441. At this time, the driving cylinder 46 starts to work, the piston rod of the cylinder 46 extends to push the clamping block 48 to approach the tray cold plate to be welded, until the tray cold plate is stably clamped between the two clamping blocks 48.

[0027] Finally, the tray cold plate clamped and fixed is accurately moved to the processing table 3 again through the cooperative driving of the driving motor one 45 and the motor two 441. Through the above-mentioned carefully designed mechanical structure and automatic process, manual intervention is effectively reduced, and at the same time, reliable fixation of the tray cold plate is realized during switching between the processing tables 3, thereby significantly reducing the error caused by workpiece misplacement in the welding process, and improving the welding precision and product quality.

[0028] An auxiliary top plate 49 is arranged between the two clamping blocks 48, and the two clamping blocks 48 are hingedly connected with the auxiliary top plate 49 through the hinge rods 50. When the cylinder 46 starts to work and the piston rod extends to push one side clamping block 48 to move linearly to the other side clamping block 48, the auxiliary top plate 49 hingedly connected between the two clamping blocks 48 will be driven by the hinge rods 50 to move towards the middle area of the two clamping blocks 48. Under the action of the driving force, the auxiliary top plate 49 moves along a specific direction to the position of the tray cold plate until it tightly contacts the surface of the tray cold plate and applies a jacking force.

[0029] At this time, the tray cold plate is reliably clamped and fixed in all directions under the combined action of the clamping force of the two clamping blocks 48 and the jacking force of the auxiliary top plate 49. This four-side clamping method can effectively limit the freedom of the tray cold plate in all directions, maximize the position stability of the tray cold plate during welding, thereby significantly improving the welding precision and ensuring that the welding quality meets the high standard requirements.

[0030] The clamping plate 43 is further provided with a rotating assembly for driving the tray cold plate to rotate; The rotating assembly comprises: a motor three 401 fixedly installed on the clamping plate 43, a rotating rod 402 fixedly connected with the output shaft of the motor three 401, and a clamping block 48 fixedly connected with the rotating rod 402; When the reverse surface processing operation needs to be performed on the tray cold plate, only the driving motor three 401 needs to be started, the output shaft of the motor three 401 rotates, and the rotating rod 402 is driven to rotate around its own axis by the transmission components such as the shaft coupling. During the rotation of the rotating rod 402, the clamping block 48 rigidly connected with the rotating rod 402 and the tray cold plate clamped and fixed on the clamping block 48 are synchronously driven to rotate in space, so that the tray cold plate is precisely flipped by 180°. Through this design, the device is endowed with the ability to continuously process the front and back surfaces of the tray cold plate, effectively expanding the functional application range of the device and improving its versatility and flexibility in different processing scenarios.

[0031] The welding mechanism 5 comprises: a mounting frame 51 fixedly installed on the machining table 3, a motor four 52 fixedly installed on the mounting frame 51, a threaded rod 53 fixedly connected with the output shaft of the motor four 52, a sliding plate 54 threadedly connected with the screw rod 41, and a welding head 55 slidingly installed on the sliding plate 54.

[0032] When the tray cold plate is carried to the position below the welding head 55, the motor four 52 drives the welding head 55 to move along the threaded rod 53, and the welding head 55 performs welding processing on the tray cold plate.

[0033] Friction welding, as an advanced solid-phase welding technology, has unique and significant advantages in the manufacturing of cold plates. Since the welding process does not require melting metal, but rather generates heat through friction to make the contact surface reach a plastic state for connection, this feature greatly reduces the size of the heat-affected zone. For cold plates, this is undoubtedly a great blessing, because excessive heat-affected zones can easily cause local overheating, which in turn can cause the cold plate to deform. However, when implementing friction welding, downward pressure needs to be applied to the welding piece to ensure the stability of the welding process and the reliability of the welding quality. However, this pressure application method may become a "double-edged sword" in certain situations. In particular, when the structure of the cold plate is relatively thin or the rigidity of the material is insufficient, excessive downward pressure may cause the welding piece to be bent during the welding process.

[0034] The machining table 3 is also provided with a jacking assembly; the jacking assembly comprises: a sliding groove 561 opened in the machining table 3, a jacking piece 562 slidingly installed in the sliding groove 561, a lead screw 563 rotationally installed in the sliding groove 561, and the lead screw 563 being in transmission connection with the output shaft of the motor four 52 through a belt 564; and the jacking piece 562 is in threaded connection with the lead screw 563. When the motor four 52 starts and drives the threaded rod 53 to rotate around its own axis, the synchronous transmission mechanism composed of the belt 564 starts to rotate synchronously under the action of the transmission force. It should be particularly pointed out that the thread pitch of the lead screw 563 and the threaded rod 53 is designed to be the same specification, which ensures the synchronization and coordination of the two.

[0035] In the process of the motor four 52 continuously rotating and driving the welding head 55 to move downward to implement the welding operation, the lead screw 563 synchronously drives the top piece 562 to move linearly due to the same pitch characteristics of the lead screw 563 and the threaded rod 53, and the movement trajectory of the top piece 562 is accurately matched with the descending trajectory of the welding head 55, so that the top piece 562 is always stably positioned directly below the welding head 55. At this time, the top piece 562 exerts a vertical upward supporting pressure on the tray cold plate placed in the working area, and the pressure balances the downward pressure exerted by the welding head 55.

[0036] This design is especially suitable for the case where the tray cold plate is thin and light or has poor material rigidity, and can effectively prevent the welding piece from being locally stressed unevenly and deformed during welding due to excessive downward pressure exerted by the welding head 55, thereby ensuring the welding quality and workpiece forming precision.

[0037] Although friction welding is a solid-phase welding that connects materials in a plastic state by generating heat through friction, local materials may be lost due to friction and extrusion during welding, especially in the case where there is a small gap between the butt surfaces or the material thickness is uneven, the loss phenomenon is more obvious, and the feeding can fill these gaps to ensure full filling of the welded joint and improve the welding quality and strength.

[0038] The welding head 55 is provided with a feeding mechanism: The feeding mechanism comprises a sleeve shaft 571 sleeved on the outside of the friction welding head 55, a storage cavity 572 and a gas outlet cavity 573 are arranged in the sleeve shaft 571, a partition plate 574 is arranged between the storage cavity 572 and the gas outlet cavity 573, a leakage port 575 is formed in the partition plate 574, a blocking rod 576 is arranged at the leakage port 575, a ring sleeve 577 is fixedly connected with the blocking rod 576, and the ring sleeve 577 is slidingly installed on the outside of the sleeve shaft 571; a pressing rod 578 is fixedly installed on the sleeve shaft 571, and a roller 579 is arranged on the pressing rod 578; and the gas outlet cavity 573 is communicated with an air inlet device.

[0039] When the welding head 55 needs to perform welding operation on the tray cold plate, it should be particularly pointed out that the sliding plate 54 is further provided with a driving mechanism for driving the welding head 55 to move vertically and linearly downward, and the driving mechanism preferably adopts a pneumatic cylinder 46, which can accurately control the downward movement of the welding head 55 by outputting stable linear driving force.

[0040] In the process of driving the welding head 55 to move downward and gradually close to the tray cold plate to implement welding, the ring sleeve 577 sleeved outside the sleeve shaft 571 will slide linearly upward along the axis direction of the sleeve shaft 571 due to the reaction force applied by the surface of the tray cold plate. When the ring sleeve 577 moves upward, it will synchronously drive the stop rod 576 rigidly connected thereto to displace upward. With the rising of the stop rod 576, the material leakage hole 575 originally in the blocked state is opened and no longer blocked by the stop rod 576.

[0041] In the process of friction welding, when the welding head 55 contacts the tray cold plate and generates friction heat to perform welding, the material replenishment mechanism can be automatically triggered to realize automatic replenishment of welding material, effectively guaranteeing the continuity of the welding process and the stability of the welding quality.

[0042] The material leakage hole 575 is a horn-shaped hole with a gradually narrowing downward direction.

[0043] It is necessary to be elaborated that the air outlet cavity 573 of the device is reasonably arranged directly below the material storage cavity 572, and the two form an upper and lower corresponding structure. When the welding head 55 is used to perform friction welding on the tray cold plate, first, the protective gas source is opened, and the protective gas is accurately delivered to the air cavity through a specific pipeline. The protective gas accumulates in the air cavity and forms a stable air flow, which is then uniformly sprayed from the air outlet of the air cavity and directly acts on the surface of the tray cold plate being welded. This protective gas not only can timely take away a large amount of heat generated in the welding process, effectively cool the tray cold plate, and prevent the material performance from changing or the welding from deforming due to local overheating; at the same time, it can also form a dense gas protection layer in the welding area, isolate oxygen in the air, and avoid oxidation reaction of the tray cold plate in the high-temperature welding environment, thereby guaranteeing the welding quality.

[0044] When the stop rod 576 moves upward under the action of the above linkage mechanism and the blockage of the material leakage hole 575 is released, the channel between the material storage cavity 572 and the air outlet cavity 573 is opened. At this time, the supplementary material pre-stored in the material storage cavity 572 begins to fall under the action of gravity and smoothly enters the air outlet cavity 573. Since there is a stable air pressure provided by the protective gas source in the air outlet cavity 573, the supplementary material will be uniformly acted upon by the air pressure after entering the air outlet cavity 573, and thus be sprayed out from the air outlet cavity 573 in the form of mist or uniform particles at a high speed, and be accurately sprayed to the working area of the welding head 55.

[0045] Through the above structure, not only the uniform spraying of the supplementary material is realized, the material jamming problem caused by the accumulation or blockage of the supplementary material is effectively prevented, and the smooth progress of the discharging process is ensured;Moreover, the supplementary material is sprayed near the welding head 55, which can timely fill the small gap or material loss that may occur during the welding process, further improving the density and quality stability of the welding. At the same time, the entire discharging process is synchronized with the protection gas supply and welding operation, without the need for additional manual intervention or complex mechanical action, significantly improving the discharging efficiency and improving the automation degree and production efficiency of the entire welding device.

[0046] Moreover, by arranging the pressing rod 578, on the one hand, the pressing rod 578 can press the tray cold plate before the welding head 55 welds the tray cold plate, improving the stability of the device, and on the other hand, the stop rod 576 connected to the other end of the pressing rod 578 moves along the surface of the tray cold plate, and the small amplitude up and down movement in the material leakage hole 575 is synchronized with the unevenness of the tray cold plate, preventing the supplementary material from being blocked in the material leakage hole 575.
