Description
Technical Field
[0001] This utility model belongs to the field of welding processing technology, and in particular relates to a precision welding device for ceramic and metal components. Background Technology
[0002] Ceramics possess high hardness, high temperature resistance, and corrosion resistance, while metals exhibit excellent electrical conductivity, thermal conductivity, and ductility. In fields such as electronic packaging and high-temperature components, combining the two can simultaneously meet the requirements of electrical insulation and heat dissipation. Therefore, brazing (filling the gap between ceramics and metals with filler metal) is commonly used to weld ceramic and metal components to meet production needs. However, currently available precision welding equipment for ceramic and metal components still suffers from the following problems during use: When welding ceramics and metals, the ceramic and metal parts need to be clamped and aligned with the parts to be welded. If different sizes of ceramic and metal parts need to be welded, different clamping devices need to be changed, which increases the cost of ceramic-metal welding. Because the ceramics and metals to be welded are of different sizes and dimensions, and the locations of the parts to be welded are also different, the position of the welding gun needs to be adjusted to meet the needs of the welding process. However, traditional precision welding devices for ceramic and metal parts cannot adjust the position of the welding gun at will, so they cannot complete the welding work for ceramic and metal parts of different sizes and dimensions. During the brazing process, liquid brazing filler metal may drip, contaminating the welding box and wasting filler metal, thus increasing the cost of ceramic-metal welding.
[0003] To address these issues, we provide a precision welding apparatus for ceramic and metal components. Utility Model Content
[0004] The purpose of this utility model is to provide a precision welding device for ceramic and metal components. By setting up a clamping assembly, a limiting groove, a slider, a connecting rod, a welding torch, and a collecting tray, it solves the problems of existing precision welding devices for ceramic and metal components being unable to clamp and align ceramic and metal components of different sizes, being unable to adjust the position of the welding torch at will, and wasting brazing filler metal.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a precision welding device for ceramic and metal devices, including a welding box, a clamping assembly and a slider; two clamping assemblies are symmetrically arranged inside the welding box; The clamping assembly clamps and aligns ceramic and metal devices of different sizes, followed by welding. A rotating shaft is rotatably connected through one side wall of the welding box, and a threaded rod is threadedly connected through one side wall of the welding box away from the rotating shaft. A clamping assembly is provided at the end of the rotating shaft and the threaded rod located inside the welding box. The clamping assembly includes a fixed plate and two moving blocks. A groove is provided on the side of the fixed plate near the center of the welding box. The two moving blocks are slidably connected to the fixed plate through the groove. An arc-shaped clamping plate is fixedly connected to the side of the moving blocks near the center of the welding box. The two clamping plates on the same clamping assembly are symmetrical about the center of the fixed plate. Place the ceramic and metal components in the center of the fixed plate between the two clamping plates, then move the positions of the two moving blocks. The two clamping plates will also move accordingly to clamp the ceramic and metal components, completing the clamping and alignment of ceramic and metal components of different sizes. The top of the welding box has two parallel through-type limit grooves, namely Limiting Groove 1 and Limiting Groove 2. The slider is slidably connected to the welding box through Limiting Groove 1 and Limiting Groove 2. A welding gun is installed inside the welding box located below Limiting Groove 1. A connecting rod is fixedly connected to the top of the welding gun, and the top of the connecting rod passes through and extends out of the slider. By moving the slider along the limiting groove, the connecting rod and welding torch can move longitudinally. By moving the connecting rod, the welding torch can move vertically.
[0006] Furthermore, a support frame is fixedly connected to the center of the bottom of the welding box, a collection tray is provided above the support frame, a collection groove is provided on the upper part of the collection tray, a support groove is provided on the lower part of the collection tray, and the upper part of the support frame is located inside the support groove. The support frame provides support for the collection tray. After welding is completed, the collection tray is removed from the support frame, and the brazing filler metal collected in the collection tank is poured out for further processing, thus enabling the collected brazing filler metal to be reused.
[0007] Furthermore, the welding box also includes a door, which is located on the side of the welding box away from the limiting groove and is hinged to the welding box. A handle is fixedly connected to the side of the door away from the welding box. When performing welding work, close the door with the handle to slow down the heat loss inside the welding chamber and isolate the inside and outside of the welding chamber to prevent the welding torch from injuring the operator. After the welding work is completed, open the door to allow the inside of the welding chamber to cool down faster.
[0008] Furthermore, one end of the rotating shaft extends into the welding box and is fixedly connected to a clamping assembly near the rotating shaft, while the other end of the rotating shaft extends out of the welding box and is fixedly connected to a handwheel; After clamping and aligning the ceramic and metal components, when performing welding, turning the handwheel will cause the rotating shaft, the clamping assembly fixedly connected to the rotating shaft, and the ceramic component clamped by the clamping assembly to rotate together. As the ceramic and metal components are attached and pressed together, the metal component will also rotate together. After one rotation, the welding of the ceramic and metal components can be completed.
[0009] Furthermore, one end of the threaded rod extends into the welding box and is rotatably connected to another clamping assembly, while the other end of the threaded rod extends out of the welding box and is fixedly connected to a crank handle; First, the ceramic component is clamped on the clamping assembly connected to the rotating shaft. Then, the metal component is clamped on the clamping assembly connected to the threaded rod. By rotating the threaded rod, the metal component will move longitudinally due to the threaded connection between the threaded rod and the welding box, and the rotational connection between the threaded rod and the clamping assembly, thus completing the alignment of the welding parts.
[0010] Furthermore, the clamping assembly also includes a rotating rod located inside the groove, the rotating rod having two opposite threads on its circumference, and each threaded segment on the rotating rod being threadedly connected to a moving block, and a cross knob being fixedly connected to the end of the rotating rod near the door; Due to the two opposing threads, when the cross knob is turned clockwise, the rotating rod will also rotate clockwise, allowing the two moving blocks to move towards the center simultaneously to clamp the ceramic and metal components. This ensures that the ceramic and metal components are fixed in the center of the fixing plate. After the welding work is completed, when the cross knob is turned counterclockwise, the rotating rod will also rotate counterclockwise, releasing the clamping plate from the ceramic and metal components, allowing the welded ceramic and metal components to be removed.
[0011] Furthermore, the second limiting groove is located at the center of the top of the welding box. A feeding pipe is provided inside the slider located in the second limiting groove. The bottom end of the feeding pipe extends through into the welding box and is fixedly connected to a feeding nozzle. The top end of the feeding pipe extends through and out of the slider, and a brazing filler metal bin is fixedly connected to the top end of the feeding pipe. During welding, the brazing filler metal in the brazing filler metal hopper falls from the feed nozzle along the feed pipe and lands above the ceramic and metal parts that need to be welded. Then, the ceramic and metal parts rotate together with the brazing filler metal. When the brazing filler metal moves to the front of the welding torch, the flame sprayed by the welding torch liquefies the brazing filler metal and fills the gap between the ceramic and metal parts, thus connecting the ceramic and metal parts.
[0012] Furthermore, a first limiting groove is provided on the top of the welding box on the side away from the box door of the second limiting groove. Three fasteners are fixedly connected in a ring array at the top of the slider above the first limiting groove, and the three fasteners are located on the periphery of the connecting rod. A wing nut is screwed into the periphery of the three fasteners. When the welding torch needs to be moved up and down, simply move the connecting rod up and down to the appropriate position, then rotate the wing nut to deform the upper ends of the three fasteners and clamp the connecting rod. Due to the fasteners and wing nut, the connecting rod will not fall, thus completing the fixation of the connecting rod and the welding torch.
[0013] Furthermore, an air pipe is fixedly connected to the end of the welding torch away from the door, the higher end of the air pipe passes through and extends out of the welding box, and an air valve is fixedly connected to the end of the air pipe extending out of the welding box. When welding, the gas valve is opened, and combustible gas is sprayed out from the welding torch along the gas pipe and burned to weld ceramic and metal parts.
[0014] Furthermore, push-pull rods are provided at the center of the limiting groove 1 and limiting groove 2 located on one side of the slider. The ends of the two push-pull rods near the slider are fixedly connected to the slider, and the ends of the two push-pull rods away from the slider are both through and extend out of the welding box. The ends of the two push-pull rods extending out of the welding box are fixedly connected to a handle. When the welding torch needs to be moved longitudinally, pull or push the handle to move or push the push-pull rod to complete the longitudinal movement of the slider, thereby completing the longitudinal movement of the welding torch.
[0015] This utility model has the following beneficial effects: This invention solves the problem of not being able to clamp or align ceramic and metal devices of different sizes by setting up a clamping assembly. The ceramic and metal devices are placed in the center of the fixed plate between the two clamping plates. The two moving blocks are moved, and the clamping plates also move accordingly. The two clamping plates clamp the ceramic and metal devices, so as to clamp ceramic and metal devices of different sizes and align them with the parts that need to be welded.
[0016] This invention solves the problem of not being able to freely adjust the position of the welding torch by setting a limiting groove, a slider, a connecting rod, and a welding torch. By adjusting the position of the slider within the limiting groove, the longitudinal movement of the welding torch can be achieved. By moving the connecting rod up and down, the vertical movement of the welding torch can be achieved, thus achieving the purpose of freely adjusting the position of the welding torch.
[0017] This invention solves the problem of wasted brazing filler metal during welding by setting up a collection tray. The brazing filler metal that splashes from the periphery of the welding part will drip into the collection groove set on the upper part of the collection tray under the action of gravity. After the collected brazing filler metal is processed, it can be reused, thereby achieving the purpose of reducing costs by reusing brazing filler metal.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1
[0031] Please see Figure 1-8 This utility model is a precision welding device for ceramic and metal devices, including a welding box 1, a clamping assembly 5 and a slider 6; two clamping assemblies 5 are symmetrically arranged inside the welding box 1. The welding box 1 provides a working environment for welding work, reducing the possibility of ceramic parts breaking due to factors such as airflow during welding. The two clamping components 5 clamp the ceramic parts and the metal parts respectively, and the welding work is carried out after aligning the welding parts. A rotating shaft 3 is rotatably connected through the center of one side wall of the welding box 1. A threaded rod 4 is threadedly connected through the center of the side wall of the welding box 1 away from the rotating shaft 3. A clamping assembly 5 is provided at the end of the rotating shaft 3 and the threaded rod 4 located inside the welding box 1. The clamping assembly 5 includes a fixed plate 501 and two moving blocks 502. A groove is opened on the side of the fixed plate 501 near the center of the welding box 1. The two moving blocks 502 are slidably connected to the fixed plate 501 through the groove. An arc-shaped clamping plate 5021 is fixedly connected to the side of the moving block 502 near the center of the welding box 1. The two clamping plates 5021 located on the same clamping assembly 5 are symmetrical about the center of the fixed plate 501. The arc-shaped clamping plate 5021 can more stably clamp ceramic and metal devices. The ceramic or metal device is placed at the center of the fixed plate 501 between the two clamping plates 5021. By moving the position of the two moving blocks 502, the two clamping plates 5021 fixedly connected to the moving plate will also move accordingly, clamping the ceramic or metal device located between the two clamping plates 5021, and completing the clamping and alignment of ceramic and metal devices of different sizes.
[0032] Among them, such as Figure 1-3 , Figure 8 As shown, the welding box 1 is equipped with a feeding nozzle 602 and a welding gun 605. The welding box 1 also includes a door 102. The door 102 is located on the side of the welding box 1 away from the limiting groove 103 and is hinged to the welding box 1. A handle 1021 is fixedly connected to the side of the door 102 away from the welding box 1. The brazing filler metal falls from the feed nozzle 602 into the part to be welded. The welding torch 605 sprays flames to weld ceramic and metal parts. During the welding operation, the door 102 is closed by the handle 1021 to slow down the heat loss inside the welding box 1, prevent the ceramic parts from breaking due to inconsistent air temperature, and isolate the inside and outside of the welding box 1 to prevent the flames sprayed by the welding torch 605 from injuring the operator. After the welding operation is completed, the door 102 is opened to allow the inside of the welding box 1 to cool down faster.
[0033] Among them, such as Figure 3 , Figure 6 As shown, one end of the rotating shaft 3 extends into the welding box 1 and is fixedly connected to the clamping assembly 5 near the rotating shaft 3, and the other end of the rotating shaft 3 extends out of the welding box 1 and is fixedly connected to the handwheel 301. After clamping and aligning the ceramic and metal components, when performing the welding work, slowly rotate the handwheel 301. The rotating shaft 3 and the clamping assembly 5 fixedly connected to the rotating shaft 3, as well as the ceramic component clamped by the clamping assembly 5, will also rotate together. Since the ceramic and metal components are in contact, the metal components will also rotate together. After rotating one revolution, the welding work of the ceramic and metal components can be completed.
[0034] Among them, such as Figure 3 , Figure 7 As shown, one end of the threaded rod 4 extends into the welding box 1 and is rotatably connected to another clamping assembly 5, while the other end of the threaded rod 4 extends out of the welding box 1 and is fixedly connected to a crank 401. First, clamp the ceramic device onto the clamping assembly 5 connected to the rotating shaft 3. Then, clamp the metal device onto the clamping assembly 5 connected to the threaded rod 4. Rotate the threaded rod 4. Due to the threaded connection between the threaded rod 4 and the welding box 1, and the rotational connection between the threaded rod 4 and the clamping assembly 5, the metal device will move longitudinally, thus completing the alignment of the welding part. Continue to rotate the threaded rod 4 to make the metal device and the ceramic device fit together and press tightly. At the same time, due to the rotational connection between the threaded rod 4 and the clamping assembly 5, when the ceramic device rotates, the metal device pressed against it and the clamping assembly 5 clamping the metal device can also rotate together.
[0035] Among them, such as Figure 6 , Figure 7 As shown, the clamping assembly 5 also includes a rotating rod 503 located inside the groove. The rotating rod 503 has two opposite threads on its periphery, and each threaded segment on the rotating rod 503 is threadedly connected to a moving block 502. A cross knob 504 is fixedly connected to one end of the rotating rod 503 near the door 102. Due to the two opposite threads, when the cross knob 504 is turned clockwise, the rotating rod 503 will also rotate clockwise, completing the simultaneous movement of the two moving blocks 502 towards the center to clamp the ceramic and metal components. This ensures that the clamping assembly 5 clamps and fixes the ceramic and metal components at the center position of the fixing plate 501. After the welding work is completed, when the cross knob 504 is turned counterclockwise, the rotating rod 503 will also rotate counterclockwise, and the clamping plate 5021 will release the clamped ceramic and metal components, allowing the welded ceramic and metal components to be removed.
[0036] The working principle of this embodiment is as follows: Before welding, the ceramic component is placed between the two clamping plates 5021 of the clamping assembly 5 connected to the rotating shaft 3. The cross knob 504 is rotated clockwise, and the rotating rod 503 also rotates clockwise. The two moving blocks 502 move towards the center simultaneously to clamp the ceramic. Then, the metal component is placed between the two clamping plates 5021 of the clamping assembly 5 connected to the threaded rod 4. The cross knob 504 is rotated clockwise to clamp the metal component. Then, the crank handle 401 is turned to rotate the threaded rod 4. Due to the threaded connection between the threaded rod 4 and the welding box 1, and the rotational connection between the threaded rod 4 and the clamping assembly 5, the metal component moves longitudinally, thus completing the alignment and clamping of the ceramic and metal component welding parts. To begin the process, close the cabinet door 102 and start the welding torch 605. The brazing filler metal falls from the feed nozzle 602 into the welding area of the ceramic and metal components. Slowly rotate the handwheel 301. The rotating shaft 3 and the clamping assembly 5, which is fixedly connected to the rotating shaft 3, as well as the ceramic component held by the clamping assembly 5, will also rotate together. As the ceramic and metal components are attached and pressed together, the metal component will also rotate together. After one rotation, the welding work of the ceramic and metal components will be completed. After the welding work is completed, pull the handle 1021 to open the cabinet door 102. After the ceramic and metal components have cooled to room temperature, turn the cross knob 504 counterclockwise. The rotating rod 503 will also rotate clockwise. The two moving blocks 502 will move to both sides at the same time, and the welded ceramic and metal components can be taken out. Specific Implementation Example 2
[0037] Please see Figure 1-4 , Figure 8 Based on the first specific embodiment, the top of the welding box 1 is provided with a parallel through-type limiting groove 103 and a limiting groove 104. The slider 6 is slidably connected to the welding box 1 through the limiting groove 103 and the limiting groove 104. The welding box 1 located below the limiting groove 103 is provided with a welding gun 605. The top of the welding gun 605 is fixedly connected to a connecting rod 604, and the top of the connecting rod 604 passes through and extends out of the slider 6. By moving the slider 6 along the limiting groove 103, the connecting rod 604 and the welding gun 605 can be moved longitudinally. By moving the connecting rod 604, the welding gun 605 can be moved vertically. By moving the welding gun 605 so that the gun head is aligned with the connection between the ceramic and metal parts, the welding work can be started by activating the welding gun 605.
[0038] Among them, such as Figure 8 As shown, the limiting groove 2 104 is located at the center of the top of the welding box 1. The slider 6 inside the limiting groove 2 104 is provided with a feeding pipe 601. The bottom end of the feeding pipe 601 extends into the welding box 1 and is fixedly connected to the feeding nozzle 602. The top end of the feeding pipe 601 extends through and out of the slider 6, and the top end of the feeding pipe 601 is fixedly connected to the brazing filler metal bin 603. When the welding torch 605 moves longitudinally, the feeding nozzle 602 also moves longitudinally. Sufficient brazing filler metal is placed in the brazing filler metal bin 603 beforehand. During the welding operation, the brazing filler metal in the brazing filler metal bin 603 falls from the feeding nozzle 602 along the feed pipe 601 under the action of gravity, falling above the ceramic and metal parts that need to be welded. Then the ceramic and metal parts rotate together with the brazing filler metal. When the brazing filler metal moves to the front of the welding torch 605, the flame sprayed by the welding torch 605 will liquefy the brazing filler metal and fill the gap between the ceramic and metal parts. Then the brazing filler metal solidifies and connects the ceramic and metal parts, thus completing the brazing operation.
[0039] Among them, such as Figure 1-4 , Figure 8 and Figure 9 As shown, a first limiting groove 103 is provided on the top of the welding box 1 located on the side of the limiting groove 104 away from the box door 102. The top of the slider 6 located above the first limiting groove 103 is fixedly connected to three fasteners 608 in a ring array. The three fasteners 608 are located around the connecting rod 604. The three fasteners 608 are threaded with a wing nut 607 on the outer periphery of the three fasteners 608. When the welding torch 605 needs to be moved up and down, simply move the connecting rod 604 up and down. After the welding torch 605 is moved to the appropriate height, rotate the wing nut 607. The fastener 608 will deform and stick tightly to the connecting rod 604. Under the action of the fastener 608 and the wing nut 607, the connecting rod 604 can no longer fall, thus completing the fixation of the connecting rod 604 and the welding torch 605 in the vertical direction.
[0040] Among them, such as Figure 3 , Figure 8 As shown, a gas pipe 6051 is fixedly connected to one end of the welding torch 605 away from the box door 102. The higher end of the gas pipe 6051 passes through and extends out of the welding box 1, and a gas valve 6052 is fixedly connected to the outside of one end of the gas pipe 6051 extending out of the welding box 1. The gas valve 6052 is connected to an external air pump, which is connected to an external combustible gas storage tank. When welding, the gas valve 6052 and the air pump are opened, and the combustible gas is sprayed out from the welding torch 605 along the gas pipe 6051 and burns, melting the brazing filler metal to perform welding work on ceramic and metal parts.
[0041] Among them, such as Figure 3 , Figure 8 As shown, push-pull rods 606 are provided at the center of the limiting groove 103 and limiting groove 2 104 located on one side of the slider 6. The ends of the two push-pull rods 606 near the slider 6 are fixedly connected to the slider 6, and the ends of the two push-pull rods 606 away from the slider 6 are both through and extend out of the welding box 1. The ends of the two push-pull rods 606 extending out of the welding box 1 are fixedly connected to a handle 6061. When it is necessary to move the welding torch 605 longitudinally, pull or push the handle 6061, which will pull or push the push-pull rod 606 to complete the longitudinal movement of the slider 6, thereby completing the longitudinal movement of the welding torch 605.
[0042] The working principle of this embodiment is as follows: After clamping the ceramic and metal components, pull or push the handle 6061 to move the connecting rod 604 up and down to adjust the position of the welding torch 605, so that the welding torch 605 is aligned with the part of the ceramic and metal components that needs to be welded. Rotate the wing nut 607, and the fastener 608 deforms and presses tightly against the connecting rod 604. Under the action of the fastener 608 and the wing nut 607, the connecting rod 604 can no longer fall, thus completing the adjustment and fixing of the welding torch 605. At this time, the feed nozzle 60... 2. Positioned directly above the welding area, close the chamber door 102. The brazing filler metal falls from the brazing filler metal chamber 603 into the area to be welded. Open the welding torch 605, and turn on the gas valve 6052 and the air pump. Combustible gas is sprayed out from the welding torch 605 along the gas pipe 6051 and burns, causing the brazing filler metal to become liquid and fill the gap between the ceramic and metal components. Subsequently, the brazing filler metal solidifies and connects the ceramic and metal components, completing the welding work between the ceramic and metal components. After the welding work is completed, close the gas valve 6052, the air pump, and the welding torch 605, and then open the chamber door 102 to cool down. Specific Implementation
[0043] Please see Figure 2-5 Based on specific embodiment one and specific embodiment two, a support frame 101 is fixedly connected to the center of the bottom of the welding box 1. A collection tray 2 is provided above the support frame 101. A collection groove 201 is provided on the upper part of the collection tray 2. A support groove 202 is provided on the lower part of the collection tray 2. The upper part of the support frame 101 is located inside the support groove 202.
[0044] The operation process of this embodiment is as follows: The support frame 101 provides support for the collection tray 2. Before the welding work is carried out, the collection tray 2 is placed on the support frame 101. The setting of the support frame 101 and the support groove 202 allows the collection tray 2 to be fixed directly below the welding part. During the welding, the brazing filler metal that has not been cured in time will fall into the collection groove 201 of the collection tray 2 below. After the welding is completed, the collection tray 2 is removed from the support frame 101, and the brazing filler metal collected in the collection groove 201 is poured out for processing, so that the collected brazing filler metal can be reused.
