Description

Technical Field

[0001] The utility model relates to the technical field of welding processing, in particular to a welding tool for a snowmobile radiator plate. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure.

[0003] After searching, the patent document with authorization announcement number CN213560789U discloses a heat sink welding tool with a positioning structure, the welding tool includes a base and a fourth hydraulic rod, support seats are installed at both ends above the base, and a fixed seat is provided on the inner side of the support seat, a motor is installed at the upper end of the fixed seat, and a bearing is installed at the right end of the inner side of the fixed seat, a rotating disk is provided at the right end of the fixed seat, and a first hydraulic rod is provided at the right end of the rotating disk, a mounting seat is provided at the right end of the first hydraulic rod, and a second hydraulic rod is provided at the front and rear ends of the mounting seat, a chuck is provided on the inner side of the second hydraulic rod, a third hydraulic rod is provided at the upper end of the base, and a processing table is installed at the upper end of the third hydraulic rod, a groove is provided at the upper end of the processing table, a stable seat is provided above the rear end of the base, the fourth hydraulic rod is located at the lower end of the stable seat, and a movable connecting seat is provided at the lower end of the fourth hydraulic rod, and the fourth hydraulic rod is connected to the welding head through the movable connecting seat.

[0004] When in use, the aforementioned welding fixture uses a support base to support and secure the fixing base, which in turn supports the motor. The motor drives the rotating disk to rotate, causing the chuck to rotate accordingly, driving the heat sink to flip over, thus achieving the flipping function. Due to the configuration of the aforementioned welding fixture, it is only suitable for single-point welding of plate-shaped products arranged side by side. It is difficult to perform vertical segment welding of iron cover plates and heat sinks.

[0005] If it is necessary to perform welding processing between the heat sink and the iron cover plate based on the above-mentioned welding tooling, it is necessary not only to set the welding head as a movable setting, but also to add an external clamp located above the heat sink. Specifically, after the heat sink is positioned and the iron cover plate is placed on the groove on the heat sink, the iron cover plate is pressed onto the heat sink using the external clamp, and then the contact parts of the two are line-segment welded using the welding head.

[0006] However, since the welding direction between the heat sink and the cover plate is generally similar to an ellipse, and the external fixtures are generally set as cylinders and hydraulic cylinders, if multiple external fixtures are set, the presence of more external fixtures will interfere with the movement of the welding head. At the same time, when the product is a special-shaped product that occupies a large space, for example, Figure 1The snowmobile heat sink shown in the figure is made of aluminum. It consists of a straight portion 101 and a curved portion 102, with a positioning hole 103 provided between the two. Under this product shape design, the number of external clamps added to press the iron cover onto the heat sink will be greater, which will cause more serious interference to the welding head and make it inconvenient for the normal welding work.

[0007] Therefore, we propose a snowmobile radiator plate welding tool to solve the above problems. Utility Model Content

[0008] The purpose of the present utility model is to solve the problems in the prior art and to propose a snowmobile heat sink welding tool. The welding tool can press the iron cover plate on the heat sink downward by setting a plurality of magnetic parts, and the plurality of magnetic parts are all located below the cover plate, which will not cause movement interference with the subsequent welding direction of the welding head, thereby ensuring the normal movement of the welding head and improving the welding efficiency.

[0009] In order to solve the above problems, the present invention provides the following technical solutions:

[0010] A snowmobile heat sink welding tool comprises a machine tool and a limiting member for pressing the heat sink onto the top of the machine tool. The welding tool also comprises a magnetic member disposed on the machine tool. When a cover plate is placed in a welding position on top of the heat sink, the magnetic member, the heat sink, and the cover plate are arranged sequentially from bottom to top so that the magnetic member exerts a downward adsorption effect on the cover plate, causing the cover plate and the heat sink to be in a fitted state. The magnetic member is provided in plurality and is evenly arranged along the welding direction.

[0011] As a further solution of the present invention: the limiting member includes a first clamp for limiting the straight portion and a second clamp for limiting the curved portion.

[0012] As a further solution of the present invention: the first clamp includes a plurality of first driving members evenly arranged around the machine tool, the execution end of the first driving member is provided with a first limit plate, and the first limit plate can move closer to or further away from the side position of the relative straight part.

[0013] As a further solution of the present invention: the first clamp also includes an auxiliary driving component arranged on the machine tool, the execution end of the auxiliary driving component is provided with an auxiliary limiting plate, and the auxiliary limiting plate can move closer to or away from the middle position of the relative straight part.

[0014] As a further solution of the present invention: the second clamp includes a plurality of second driving members evenly arranged on both sides of the machine tool, the execution end of the second driving member is provided with a second limit plate, and the second limit plate can move closer to or away from the curved part.

[0015] As a further solution of the present invention: the second fixture includes a plurality of second driving members evenly arranged on both sides of the machine tool, the execution end of the second driving member is rotatably provided with a carrier plate, and the bottom of the carrier plate is fixedly provided with a plurality of profiling blocks along its length direction, and the plurality of profiling blocks can move close to or away from the curved part.

[0016] As a further solution of the present invention: the second limiting plate is configured as a contoured plate that is adapted to the curved structure of the heat dissipation plate.

[0017] As a further solution of the present invention: the welding tool also includes a positioning pin shaft arranged on the top of the machine tool and used for inserting into the positioning hole on the heat sink.

[0018] As a further solution of the present invention: the positioning pin is movably arranged on the top of the machine tool and can be raised and lowered on the machine tool.

[0019] As a further solution of the present invention: the welding tool also includes a feeding robot arm arranged on the machine tool, and the feeding robot arm is used to grab the cover plate and transport it to the heat sink.

[0020] As a further solution of the present invention: the carrier plate is movably arranged on the execution end of the second driving member, so that the whole composed of the multiple profiling blocks is in a multi-freedom movable state.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Through the setting of the magnetic suction piece, the cover plate on the heat sink can be adsorbed by the magnetic suction piece, so that the cover plate is tightly fitted to the top of the heat sink. The contact part between the heat sink and the cover plate constitutes the welding direction. The position of the magnetic suction piece will not interfere with the welding direction. In the subsequent welding process of the welding head, the welding head can perform corresponding line segment welding, which makes the welding smooth, avoids the occurrence of many pauses, and improves the welding effect.

[0023] 2. The integral profiling plate design in the second fixture can adapt to the curved structure of the heat sink, so that the profiling plate can adaptably press the curved portion of the heat sink, achieving a good pressing effect.

[0024] 3. Compared with the above-mentioned integral profiling plate design, the multiple split profiling blocks in the second fixture can better increase the contact area with the curved portion of the heat sink, so that the heat sink will not be deformed during the pressing process. At the same time, the multi-point pressing at the curved portion also complies with the dimensional tolerance of the heat sink.

[0025] 4. The multiple profiling blocks are all movably arranged so that they can adapt to the curved portion of the heat sink during the pressing process, ensuring that at least two surfaces are in contact with the curved portion, further improving the pressing effect.

[0036] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1:

[0038] like Figure 2-Figure 5 As shown, a snowmobile heat sink welding tool includes a machine tool 1. The top of the machine tool 1 is configured to be composed of a horizontal portion and a curved portion adapted to fit the heat sink 10. During use, the straight portion 101 of the heat sink 10 can be placed on the horizontal portion, and the curved portion 102 of the heat sink 10 can be placed on the curved portion. During this process, to ensure that the heat sink 10 can be placed in a designated position on the machine tool 1, a positioning pin 4 can be provided on the top of the machine tool 1 for inserting into a positioning hole 103 on the heat sink 10. The positioning pin 4 can be raised or lowered. The heat sink 10 is then pressed as a whole using a limiter provided on the machine tool 1, so that the position of the heat sink 10 on the machine tool 1 remains stable. The cover plate can then be grasped by a feeding robot 5 provided on the machine tool 1 and released at the designated position to be welded on the heat sink 10, so that the portion of the cover plate in contact with the heat sink 10 forms the corresponding direction to be welded.

[0039] like Figure 2 As shown, in order to ensure that the cover plate and the heat sink 10 can maintain relative stability, a magnetic component 6 can be provided on the machine tool 1. When the cover plate is placed in the welding position on top of the heat sink 10, the magnetic component 6, the heat sink 10 and the cover plate are arranged in sequence from bottom to top, so that the magnetic component 6 produces a downward adsorption effect on the cover plate, causing the cover plate and the heat sink 10 to be in a fitted state. There are multiple magnetic components 6 and they are evenly arranged along the welding direction. This magnetic component 6 is provided at a position below the heat sink 10 and will not interfere with the welding direction between the heat sink 10 and the cover plate, so that in the subsequent welding process using the welding head, the movement direction of the welding head will not be disturbed, thereby ensuring the welding effect. After the welding is completed, the positioning pin 4 can be lowered until the positioning pin 4 moves out of the positioning hole 103, and then the limit of the heat sink 10 by the limiting component can be released to take out the heat sink 10 and the cover plate. As shown Figure 2 As shown, the magnetic element 6 is arranged on the top of the machine tool 1, and its specific layout can be set according to the actual placement position of the heat sink 10, which will not be enumerated here.

[0040] like Figure 3-Figure 5 As shown, for the arrangement of the above-mentioned middle limiter, since the heat sink 10 is composed of a straight portion 101 and a curved portion 102, the limiter is adapted to include a first clamp 2 for limiting the straight portion 101 and a second clamp 3 for limiting the curved portion 102. Specifically, the first clamp 2 and the second clamp 3 are arranged as follows:

[0041] (1) The first fixture 2 includes a plurality of first driving members 201 evenly arranged around the machine tool 1 and an auxiliary driving member 203 provided on the machine tool 1. The first driving member 201 is provided with a first limiting plate 202 at its execution end, and the first limiting plate 202 can move closer to or further away from the side position of the straight portion 101. When the heat sink 10 is placed on the machine tool 1, the first driving member 201 is operated so that the first limiting plate 202 is pressed against the side position of the straight portion 101 on the heat sink 10. The auxiliary driving member 203 is provided with an auxiliary limiting plate 204 at its execution end, and the auxiliary limiting plate 204 can move closer to or further away from the middle position of the straight portion 101. When the heat sink 10 is placed on the machine tool 1, the auxiliary driving member 203 is operated so that the auxiliary limiting plate 204 is pressed against the middle position of the straight portion 101 on the heat sink 10. The first driving member 201 and the auxiliary driving member 203 can both be air cylinders, oil cylinders or telescopic rods.

[0042] (2) The second fixture 3 includes a plurality of second driving members 301 evenly arranged on both sides of the machine tool 1. The execution end of the second driving member 301 is provided with a second limiting plate 302, and the second limiting plate 302 can move closer to or away from the curved portion 102. When the heat sink 10 is placed on the machine tool 1, the second driving member 301 is operated so that the second limiting plate 302 is pressed against the curved portion of the heat sink 10. The second driving member 301 can be a pneumatic cylinder, an oil cylinder, or a telescopic rod. In order to adapt to the structure of the curved portion 102 on the heat sink 10, the second limiting plate 302 can be set as a contour plate that is adapted to the structure of the curved portion 102 on the heat sink 10, so that the contour plate can adaptively press the curved portion 102 of the heat sink 10, and the pressing effect is good.

[0043] Example 2:

[0044] like Figure 6-Figure 8As shown, this embodiment differs from the first embodiment in that the second fixture 3 for engaging the curved portion of the heat sink 10 is improved. Specifically, the second fixture 3 includes multiple second driving members 301 evenly arranged on both sides of the machine tool 1. The actuating end of the second driving member 301 is rotatably provided with a carrier plate 303, and the bottom of the carrier plate 303 is fixedly provided with multiple profiling blocks 304 along its length. The multiple profiling blocks 304 can move closer to or further away from the curved portion 102. Compared to the integral profiling block design in the first embodiment, the multiple profiling blocks 304 in this embodiment can better increase the contact area with the curved portion 102 of the heat sink 10, preventing the heat sink 10 from being deformed during the pressing process. At the same time, the multi-point pressing at the curved portion 102 also accommodates the dimensional tolerance of the heat sink 10. Furthermore, the carrier plate 303 can be movably set on the execution end of the second driving member 301, that is, the whole composed of multiple contour blocks 304 is in a multi-degree-of-freedom movable state, so that it can adapt to the curved portion 102 of the heat sink 10 during the pressing process, further improving the pressing effect.

[0045] like Figure 6 As shown, on the basis of the above-mentioned embodiment 2, several welding robots 7 can be additionally provided, so that after the heat sink 10 and the cover plate are in a clamped and fixed state, the welding robots 7 can be used to quickly weld the two.

[0046] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
