[0002] Aluminum alloy has the advantages of low density, high structural strength, and corrosion resistance. Aluminum metal resources are abundant in the earth's crust, so it is relatively cheap and is a very suitable metal material for making heat sinks for motor housings. However, since the thermal expansion coefficient of aluminum alloy itself is high, and the thermal expansion coefficient will further increase at high temperatures, it is very easy to cause deformation of aluminum products.

[0003] Especially when welding the heat sink of the motor casing, the high temperature generated by the welding machine will reduce the strength of the aluminum plate, and the high temperature will also enhance the plasticity of the material, causing deformation of the aluminum plate. For this reason, the applicant proposed a new technical solution, which automatically clamps and fixes the base material and the heat sink through hydraulic components, and fixes the shape and position of the weldment in the form of a tooling, thereby avoiding deformation of the heat sink and the base material.

DETAILED DESCRIPTION

[0035] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part 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 creative work are within the scope of protection of the present invention.

[0036] Please refer to Figure 1-Figure 6 The utility model discloses a heat sink welding tool, which is suitable for aligning and abutting a parent material with a heat sink. The specific technical solution of the utility model is described below.

[0037] like Figure 1 , the device mainly includes a linked cylinder 1, a base 3 and a clamping mechanism 5, wherein the linked cylinder 1 is provided with pressure by a servo pump station to push the piston rod of the linked cylinder 1 to move, and a positioning block 6 is installed at the end of the piston rod, and the positioning block 6 is used to clamp the parent material connected to the heat sink so that the welding gun can align the weld for welding. In terms of structure, the bottom of the linked cylinder 1 is set on a quick clamping slide 2, and the quick clamping slide 2 is slidably set on a guide rail 4 located at the top of the base 3, and the quick clamping slide 2 has a locking and fixing function, so the quick clamping slide 2 can abut and be fixed at any position of the guide rail 4, so as to weld parent materials of different sizes. On the other hand, the parent material needs to be welded on the heat sink. Since a large number of heat sink fins are arranged on the heat sink, in order to prevent the heat sink fins from being deformed by heat, when welding, a limit block 7 needs to be used to fix the heat sink fins and the heat sink. In this embodiment, the clamping mechanism 5 is set at the end of the base 3, and a limit block 7 is installed inside the clamping mechanism 5. When welding is specifically implemented, the clamping mechanism 5 will press and fix the heat sink, and at the same time, the linked cylinder 1 will push the base material to abut against the end of the heat sink through the positioning block 6, and use the positioning block 6, the limit block 7 and the clamping mechanism 5 to jointly press the base material and the heat sink, thereby avoiding the problem of deformation of the aluminum alloy profile due to thermal expansion.

[0038] In this embodiment, if Figure 2 The limiting block 7 is made of nylon, and the bottom of the limiting block 7 is fixed on the workbench 51, and the top is provided with a limiting groove for clamping the heat sink fins, thereby fixing and protecting the heat sink fins.

[0039] In a specific embodiment disclosed in the present utility model, Figure 3 and Figure 6The positioning block 6 is made of solid steel, and a groove is provided on the outer side thereof to abut against the busbar. Alternatively, the positioning block 6 may also be a hollow structure, and a channel is provided inside the positioning block 6, and a coolant or compressed air flow is passed into the channel, so that the positioning block 6 has a heat absorption function, thereby accelerating the welding shaping time.

[0040] In some embodiments, Figure 3 and Figure 5 The linked cylinder 1 includes a cylinder base 11 and a cylinder barrel 13. A pair of internal threaded holes 14 are provided at the bottom of the cylinder base 11. Fasteners are installed in the internal threaded holes 14 so as to be screwed and fixed with the quick clamping slide 2. A cover plate 15 is tiltedly provided on the top of the cylinder base 11. A plurality of cylinder barrels 13 are evenly provided on the cover plate 15. The cylinder barrels 13 are connected to the servo pump station. The plurality of cylinder barrels 13 are started synchronously to push the positioning block 6 to move.

[0041] In the previous embodiment, if Figure 3 and Figure 4 Optionally, a through hole 12 is provided at the bottom of the cylinder seat 11, and a guide column 25 is vertically provided on the top of the seat body 21 of the quick clamping slide 2. The through hole 12 is sleeved on the guide column 25. At the same time, a lifting bolt 8 is threaded in the internal threaded hole 14, and the bottom of the lifting bolt 8 is connected to the seat body 21. Therefore, by rotating the lifting bolt 8, the cylinder seat 11 can be moved up and down, and at the same time, the quick clamping slide 2 slides on the guide rail 4, so that the heat sink and the busbar can be effectively limited.

[0042] In some embodiments, Figure 4 The quick clamping slide 2 includes a seat body 21 and a wrench 23. A slide groove 22 is provided at the bottom of the seat body 21. The slide groove 22 is slidably provided on the guide rail 4, and a clamping groove 26 is provided on the slide groove 22. The clamping groove 26 intersects with the slide groove 22. In addition, a wrench 23 is hingedly provided at the top of the seat body 21. A locking ring 24 is installed on the wrench 23, and the locking ring 24 is suitable for sliding in the clamping groove 26. When the wrench is turned upward, the wrench 23 drives the locking ring 24 to move along the clamping groove 26. When the wrench 23 is turned to the dead point position, the locking ring 24 is pressed against the guide rail 4, so that the position of the seat body 21 on the guide rail 4 can be effectively fixed by the static friction between the locking ring 24 and the guide rail 4.

[0043] In this embodiment, the guide rail 4 is provided with a scale (not shown in the drawings). The scale marked on the guide rail 4 can not only be used to determine whether the seat body 21 has relative sliding, but also to adjust the position of the seat body 21 on the guide rail 4 according to the specific size of the profile.

[0044] In some embodiments, Figure 2The clamping mechanism 5 includes a workbench 51 and a clamping cylinder 53, wherein the bottom of the workbench 51 is installed on the base 3, and a frame beam 52 is arranged on the top of the workbench 51, and a clamping cylinder 53 is invertedly arranged on the frame beam 52, and the piston rod of the clamping cylinder 53 is connected to the pressing block 54, and the pressing block 54 is suitable for pressing and fixing the heat sink on the limit block 7 located on the workbench 51, so as to avoid squeezing the heat sink fins while pressing the heat sink, which may cause damage to the heat sink.

[0045] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
