Description

Technical Field

[0001] This utility model relates to the field of laser welding, specifically a welding system. Background Technology

[0002] Titanium-aluminum composite material is a compressible compound of two materials, titanium and aluminum. The existing hole processing of titanium-aluminum composite material mainly involves feeding a titanium wire to the bottom of a pre-machined hole in the aluminum material, then heating and melting the titanium wire with a laser. The molten titanium wire is then cooled naturally before the hole is finally processed.

[0003] However, since the melting point of titanium is 1668℃, while that of aluminum is 660℃, the melting point of titanium is much higher than that of aluminum. Therefore, when titanium wire is heated and melted by laser, if the melting temperature of the titanium wire cannot be reduced in time, it can easily cause the aluminum material around the pre-machined hole to melt and collapse. It can also cause the aluminum material to be incorporated into the titanium liquid and form impurities, which will seriously affect the subsequent hole processing. Utility Model Content

[0004] In view of this, the present invention provides a welding system to solve the problems of melting and collapsing of the aluminum material around the pre-machined hole position due to the inability to reduce the temperature of the titanium wire during the hot melting process of existing titanium-aluminum composite material holes, and the problem of aluminum material being incorporated into the titanium liquid to form impurities, which in turn affects subsequent hole processing.

Detailed Implementation

[0037] 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.

[0038] This utility model provides a welding system, see [link]. Figure 1 and combined Figures 2 to 5 The welding system includes:

[0039] Workbench 1;

[0040] The moving mechanism 2 is located on the workbench 1;

[0041] A heat-conducting base 3 is disposed on the moving mechanism 2. The heat-conducting base 3 is provided with a cooling channel 31 for coolant to pass through, and the heat-conducting base 3 has a bearing position for supporting the workpiece to be welded.

[0042] A locking assembly is provided on the heat-conducting base 3. The locking assembly is used to fix the workpiece to be welded to the bearing position.

[0043] The laser integration system 5 is set on the worktable 1 and is used to weld the workpiece to be welded, which is fixed at the bearing position.

[0044] It should be noted that the heat-conducting base 3 is set in the moving mechanism 2, so that the moving mechanism 2 can move the workpiece to be welded located in the bearing position to the welding area of ​​the laser integrated system 5 for welding.

[0045] By setting a cooling channel 31 for coolant to pass through the heat-conducting base 3, coolant can be injected into the cooling channel 31. When the laser integration system 5 welds the workpiece to be welded on the bearing position, the heat generated by welding is transferred to the heat-conducting base 3, and then the heat of the heat-conducting base 31 is carried away by the coolant in the cooling channel 31, thereby achieving rapid cooling of the heat-conducting base 3.

[0046] This embodiment of the invention includes a worktable 1, a moving mechanism 2, and a heat-conducting base 3. The heat-conducting base 3 has a cooling channel 31 for coolant passage and a support position for supporting the workpiece to be welded. A locking assembly for fixing the workpiece to be welded to the support position is also provided on the heat-conducting base 3. A laser integrated system 5 for welding the workpiece fixed to the support position is provided on the worktable 1. With the welding system disclosed above, since this application can remove the heat from the heat-conducting base 3 through coolant during welding, achieving rapid cooling of the heat-conducting base 3, when machining holes in titanium-aluminum composite materials using the welding fixture of this application, the temperature of the titanium wire melt can be quickly reduced by coolant, thereby preventing the aluminum material around the pre-machined hole from melting and collapsing, and effectively preventing the aluminum material from merging into the titanium liquid to form impurities, ensuring the subsequent hole machining.

[0047] Specifically, the heat-conducting base 3 has multiple support protrusions 32 on its support position. The support protrusions 32 are elongated structures extending along the first direction, and the multiple support protrusions 32 are spaced apart along the second direction.

[0048] It should be noted that the supporting protrusion 32 can be a long strip structure or other shapes, and those skilled in the art can choose according to their needs.

[0049] It should also be noted that by setting the bearing protrusion 32 as a long strip structure and setting multiple bearing protrusions 32 at intervals along the second direction, multiple parts to be welded can be placed one by one on the bearing protrusion 32. The heat generated by the welding of the parts to be welded on each bearing protrusion 32 can be quickly carried away by the coolant, thereby achieving rapid cooling of the parts to be welded on multiple bearing protrusions 32.

[0050] Furthermore, there are multiple cooling channels 31, which are evenly distributed on the heat-conducting base 3.

[0051] It should be noted that by setting multiple cooling channels 31 and distributing them evenly on the heat-conducting base 3, the coolant can uniformly cool and reduce the temperature of each part of the heat-conducting base 3, thereby improving the cooling and temperature reduction effect of the heat-conducting base 3.

[0052] Specifically,

[0053] Multiple cooling channels 31 are spaced apart on the heat-conducting base 3 along the first direction, and all of them penetrate the heat-conducting base 3 along the second direction, wherein the second direction is set at an angle to the first direction.

[0054] It should be noted that multiple cooling channels 31 are spaced apart along the first direction on the heat-conducting base 3, and all of them penetrate the heat-conducting base 3 along the second direction. The second direction is set at an angle to the first direction. Thus, the heat transferred by each bearing protrusion 32 to the heat-conducting base 3 can be carried away by the coolant in the multiple cooling channels 31, ensuring that the welded parts on each bearing protrusion 32 can be cooled down quickly.

[0055] Preferably, the first direction is perpendicular to the second direction.

[0056] It should be noted that the first direction can be perpendicular to the second direction or set at a 45° angle, and those skilled in the art can choose according to their needs.

[0057] Furthermore, the locking assembly includes: a first locking mechanism 41 and a second locking mechanism 42;

[0058] The first locking mechanism 41 and the second locking mechanism 42 are both disposed on the heat-conducting base 3 and are located at both ends of the bearing position, respectively. The first locking mechanism 41 and the second locking mechanism 42 are used to fix the clamping fixture 10 to the heat-conducting base 3.

[0059] It should be noted that by setting the first locking mechanism 41 and the second locking mechanism 42, the clamping fixture 10 and the heat-conducting base 3 can be fixed together (e.g., by using the first locking mechanism 41 and the second locking mechanism 42). Figure 4 (As shown).

[0060] It should also be noted that the clamping fixture 10 is mainly used to clamp materials so that the materials come into contact with the bearing protrusion 32.

[0061] Furthermore, the welding system also includes: a water distributor 6;

[0062] The water distributor 6 is located on one side of the heat-conducting base 3 and has a first water inlet and a first water outlet, wherein the number of the first water outlets is the same as the number of cooling channels 31.

[0063] Each first water outlet is connected to one end of the corresponding cooling channel 31 via a pipe.

[0064] It should be noted that by setting up a water distributor 6 and configuring it as a first inlet and a first outlet, with the number of first outlets being the same as the number of cooling channels 31, and by connecting each first outlet to one end of the corresponding cooling channel 31 via a pipe (not shown in the figure), the coolant in the multiple cooling channels 31 can flow through the shortest path. Therefore, the coolant in the multiple cooling channels 31 can simultaneously and quickly remove the heat from the heat-conducting base 3, achieving rapid cooling of the heat-conducting base 3.

[0065] It should also be noted that the water distributor 6 of this application is specifically a cylindrical structure, with one end of the cylindrical body being the first water inlet and the other end being the closed end, and the outer wall of the cylindrical body having multiple first water outlets along its axial direction.

[0066] Preferably, the diameter of the first inlet of the water distributor 6 is 8mm, and the diameter of the first outlet of the water distributor 6 is 6mm.

[0067] Furthermore, the welding system also includes: a water collector 7;

[0068] The water collector 7 is located on the side of the heat-conducting base 3 away from the water distributor 6, and has a second water outlet and a second water inlet. The number of second water inlets of the water collector 7 is the same as the number of cooling channels 31.

[0069] Each second water inlet is connected to the other end of the corresponding cooling channel 31 via a pipe.

[0070] It should be noted that by setting up a water collector 7, and setting a second water outlet and a second water inlet in the water collector 7, and making the number of second water inlets of the water collector 7 the same as the number of cooling channels 31, and connecting each second water inlet to the other end of the corresponding cooling channel 31 through a pipe (the pipe is not shown in the figure), it is possible to achieve unified collection and treatment of coolant.

[0071] It should also be noted that the water collector 7 of this application is specifically a cylindrical structure, with one end of the cylindrical body being the second water outlet and the other end being the closed end, and the outer wall of the cylindrical body having multiple second water inlets along its axial direction.

[0072] It is worth noting that the water collector 7 and the water distributor 6 of this application are symmetrically arranged on both sides of the heat-conducting base 3.

[0073] Preferably, the support protrusion 32 is made of copper.

[0074] It should be noted that the bearing protrusion 32 can be made of copper or other materials with good thermal conductivity. Those skilled in the art can choose according to their needs.

[0075] Specifically, the laser integration system 5 includes: a lifting mechanism 51 and a laser welding assembly 52;

[0076] The laser welding assembly 52 is mounted on the lifting mechanism 51, which is used to drive the laser welding assembly 52 to move up and down.

[0077] It should be noted that when the laser welding assembly 52 is set on the lifting mechanism 51, and the moving mechanism 2 moves the heat-conducting base 3 to the welding position, the lifting mechanism 51 can drive the laser welding assembly 52 to rise and fall, so that the laser welding assembly 52 can weld the workpiece to be welded on the bearing position of the heat-conducting base 3.

[0078] Preferably, the lifting mechanism 51 includes: a support frame, a motor, a lead screw, a slide rail, and a mounting base;

[0079] The slide rail is vertically mounted on the support frame;

[0080] The motor is located at one end of the slide rail, and one end of the lead screw is connected to the motor shaft for transmission.

[0081] The mounting base is slidably mounted on the slide rail and has a threaded hole that mates with the lead screw thread;

[0082] The laser integrated system 5 is installed on the mounting base.

[0083] It should be noted that by driving the lead screw with a motor, the mounting base can move axially along the lead screw, thus enabling the vertical lifting and lowering of the laser integrated system 5. For details, please refer to... Figure 5 The welding system also includes: condenser 8;

[0084] The outlet of the condenser 8 is connected to the inlet of the cooling channel 31 via a pipe, and the inlet of the condenser 8 is connected to the outlet of the cooling channel 31 via a pipe.

[0085] It should be noted that by setting up a condenser 8 and connecting the outlet of the condenser 8 to the inlet of the cooling channel 31 through a pipe, and connecting the inlet of the condenser 8 to the outlet of the cooling channel 31 through a pipe, the coolant after the heat-conducting base 3 has been cooled can be cooled down. Then, the cooled coolant is transported to the heat-conducting base 3 through a pipe for further cooling. Therefore, by setting up a condenser 8, this application can not only achieve rapid cooling of the heat-conducting base 3, but also achieve the recycling of coolant.

[0086] Furthermore, the welding system also includes: an image acquisition device 9 for acquiring images of the workpiece to be welded;

[0087] The image acquisition device 9 is positioned above the heat-conducting base 3.

[0088] It should be noted that by setting up an image acquisition device 9 for acquiring images of the workpiece to be welded, and placing the image acquisition device 9 above the bearing position, the image of the workpiece to be welded is acquired by the image acquisition device 9 before welding. Then, the laser integration system 5 aligns and welds the workpiece to be welded according to the position of the workpiece to be welded in the image.

[0089] Preferably, the image acquisition device 9 is a camera.

[0090] Preferably, the welding system further includes: a wire box for holding the welding wire and a wire shaping machine for shaping the welding wire;

[0091] Both the junction box and the cable assembly are mounted on the support frame.
