Description

Auxiliary tooling for friction welding of communication housing Technical Field

[0002] With the development of communication technology, 4G and 5G communication equipment have been widely used, and 6G communication equipment is gradually being developed. The communication housing is a key component of communication equipment. Communication housings usually have heat dissipation components, and some communication housings use liquid-cooled heat sinks for heat dissipation. Liquid-cooled heat sinks are usually welded to the communication housing by friction welding.

[0003] In the prior art, during the friction welding of liquid cooling heat sinks to the communication housing, a support fixture is usually provided to support the communication housing. The shape of the support fixture corresponds to the inner shape of the communication housing. When the communication housing is placed on the support fixture, the support fixture can support the communication housing. However, the following technical problems still exist in the friction welding process of the communication housing: (1) During the friction welding process, the welding head is not always in a vertical welding state, and sometimes it is in an oblique welding state. When the welding head is in an oblique welding state, it will give the communication housing a large lateral thrust, and the communication housing is prone to lateral displacement or deformation; (2) During the friction welding process, the communication housing is also prone to vibration and jumping, making it difficult to guarantee the welding quality of the communication housing.

[0014] Figure 1 shows the overall structure of the auxiliary tooling for friction welding of communication housings.

[0015] Figure 2 shows the distributed structure of the auxiliary tooling for friction welding of communication housings.

[0016] Figure 3 is a schematic diagram of the structure of the auxiliary tooling for friction welding of communication housing, which supports and positions the communication housing. Detailed Implementation

[0017] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] As shown in Figures 1-3, this utility model is an auxiliary tooling for friction welding of a communication housing, including a tooling base 1, a support frame 2 in the middle of the tooling base 1, and a communication housing 10 supported on the support frame 2; a first side-supporting device 3 for supporting the front side of the communication housing 10 and a first pressing device 4 for pressing the front side of the communication housing 10 downward are installed on the front end of the tooling base 1; a second side-supporting device 5 for supporting the left side of the communication housing 10 and a second pressing device 6 for pressing the left side of the communication housing 10 downward are installed on the left end of the tooling base 1; a third side-supporting device 7 for supporting the rear side of the communication housing 10 and a third pressing device 8 for pressing the rear end of the communication housing 10 downward are installed on the rear end of the tooling base 1. It should be noted that, as shown in Figure 3, since the right end of the communication housing 10 extends outward from the right end of the fixture base 1, occupying the right end space of the fixture base 1, and only the left end of the communication housing 10 needs to be welded with liquid cooling heat sinks, while the right end of the communication housing 10 does not need to be welded with liquid cooling heat sinks, therefore, there is no need to set up a side top device and a clamping device on the right end of the fixture base 1.

[0019] As shown in Figure 3, when it is necessary to friction weld the liquid cooling heat sink 101 to the communication housing 10, the communication housing 10 is first placed on the support frame 2; then, the first side-supporting device 3 is controlled to support the front side of the communication housing 10, the second side-supporting device 5 is controlled to support the left side of the communication housing 10, and the third side-supporting device 7 is controlled to support the rear side of the communication housing 10; next, the first pressing device 4 is controlled to press the front end of the communication housing 10, the second pressing device 6 is controlled to press the left end of the communication housing 10, and the third pressing device 8 is controlled to press the rear end of the communication housing 10; then, the friction welding equipment is controlled to perform the friction welding process. In the friction welding process, the first side-supporting device 3, the second side-supporting device 5, and the third side-supporting device 7 can respectively press the communication housing 10 from three directions to prevent the communication housing 10 from lateral displacement or deformation. In the friction welding process, the first pressing device 4, the second pressing device 6, and the third pressing device 8 can respectively press the front end, the left end, and the rear end of the communication housing 10 to avoid the communication housing 10 from jumping due to vibration, so as to ensure the welding quality of the communication housing 10.

[0020] As shown in Figures 1 and 2, the support frame 2 is a hollow frame with a central through-section. The support frame 2 is a contour-following support structure that corresponds to the inner shape of the communication housing 10. The hollow cavity allows dust generated during the welding process to fall out; the contour-following support structure ensures that the support frame 2 matches the inner shape of the communication housing 10, resulting in more stable support.

[0021] As shown in Figures 1-3, the first side-top device 3 includes a first upright plate 31. A first side-top cylinder 32 is horizontally mounted on the side of the first upright plate 31 away from the supporting frame 2. The piston rod of the first side-top cylinder 32 extends towards the front of the supporting frame 2. The piston rod of the first side-top cylinder 32 is connected to a first top plate 33. When the piston rod of the first side-top cylinder 32 extends, it can drive the first top plate 33 to press against the front of the communication housing 10. The second side-top device 5 includes a second upright plate 51. A second side-top cylinder 52 is horizontally mounted on the side of the second upright plate 51 away from the supporting frame 2. The piston rod of the second side-top cylinder 52 extends... To the left of the support frame 2, the piston rod of the second side top cylinder 52 is connected to the second top plate 53. When the second side top cylinder 52 drives the piston rod to extend, it can drive the second top plate 53 to press against the left side of the communication housing 10. The third side top device 7 includes a third vertical plate 71. The third side top cylinder 72 is horizontally installed on the side of the third vertical plate 71 away from the support frame 2. The piston rod of the third side top cylinder 72 extends to the rear side of the support frame 2. The piston rod of the third side top cylinder 72 is connected to the third top plate 73. When the third side top cylinder 72 drives the piston rod to extend, it can drive the third top plate 73 to press against the rear side of the communication housing 10.

[0022] As shown in Figures 1-3, two first side-mounted cylinders 32 are arranged side-by-side, with the piston rod of one first side-mounted cylinder 32 connected to one end of the first top plate 33 and the piston rod of the other first side-mounted cylinder 32 connected to the other end of the first top plate 33; two second side-mounted cylinders 52 are arranged side-by-side, with the piston rod of one second side-mounted cylinder 52 connected to one end of the second top plate 53 and the piston rod of the other second side-mounted cylinder 52 connected to the other end of the second top plate 53; two third side-mounted cylinders 72 are arranged side-by-side, with the piston rod of one third side-mounted cylinder 72 connected to one end of the third top plate 73 and the piston rod of the other third side-mounted cylinder 72 connected to the other end of the third top plate 73. Because this invention features two first side-mounted cylinders 32, two second side-mounted cylinders 52, and two third side-mounted cylinders 72 arranged side-by-side, the side-mounting forces of the first top plate 33, second top plate 53, and third top plate 73 are balanced, stable, and reliable.

One end of the first pressing beam 42 is connected to the first pressing rod 43. When the first pressing cylinder 41 drives the piston rod to retract downward, it can drive the first pressing beam 42 and the first pressing rod 43 to move downward, and cause one end of the first pressing beam 42 to rest on the first upright plate 31. The other end of the first pressing beam 42 pushes the first pressing rod 43 to press the front end of the communication housing 10. The second pressing device 6 includes a second pressing cylinder 61, a second pressing beam 62, and a second pressing rod 63. The second pressing cylinder 61 is vertically mounted on the left end of the tooling base 1. The piston rod of the second pressing cylinder 61 extends upward and connects to the middle of the second pressing beam 62. The second pressing beam 62... One end of the device is connected to the second pressure rod 63. When the piston rod of the second pressing cylinder 61 retracts downward, it can drive the second pressing beam 62 and the second pressure rod 63 to move downward, and make one end of the second pressing beam 62 rest on the second vertical plate 51. The other end of the second pressing beam 62 pushes the second pressure rod 63 to press the left end of the communication housing 10. The third pressing device 8 includes a third pressing cylinder 81, a third pressing beam 82 and a third pressure rod. The third pressing cylinder 81 is vertically installed on the rear end of the tooling base 1. The piston rod of the third pressing cylinder 81 extends upward and is connected to the middle of the third pressing beam 82. One end of the third pressing beam 82 is connected to the third pressure rod 83. When the piston rod of the third pressing cylinder 81 retracts downward, it can drive the third pressing beam 82 and the third pressure rod 83 to move downward, and make one end of the third pressing beam 82 rest on the third vertical plate 71. The other end of the third pressing beam 82 pushes the third pressure rod 83 to press the rear end of the communication housing 10.

[0024] As shown in Figures 1-3, the first pressure beam 42 has a first elongated slot 421 in the middle, through which the piston rod of the first pressing cylinder 41 moves. The top of the piston rod is provided with a first anti-detachment cap 44 to prevent the piston rod from coming loose from the first elongated slot 421. The second pressure beam 62 has a second elongated slot 621 in the middle, through which the piston rod of the second pressing cylinder 61 moves. The top of the piston rod is provided with a second anti-detachment cap 64 to prevent the piston rod from coming loose from the second elongated slot. The third pressure beam 82 has a third elongated slot 821 in the middle, through which the piston rod of the third pressing cylinder 81 moves. The top of the piston rod is provided with a third anti-detachment cap 84 to prevent the piston rod from coming loose from the third elongated slot. When the piston rods of the first clamping cylinder 41, the second clamping cylinder 61, and the third clamping cylinder 81 retract downwards, they can drive the first pressure beam 42, the second pressure beam 62, and the third pressure beam 82 to move downwards via the first anti-detachment cap 44, the second anti-detachment cap 64, and the third anti-detachment cap 84. When the piston rods of the first clamping cylinder 41, the second clamping cylinder 61, and the third clamping cylinder 81 extend upwards, they can move upwards through the first elongated slot 421, the second elongated slot 621, and the third elongated slot 821, respectively. At this time, the first pressure beam 42, the second pressure beam 62, and the third pressure beam 82 are in an active state and can be manually raised and rotated, causing the first pressure rod 43, the second pressure rod 63, and the third pressure rod 83 to leave the communication housing 10, respectively.

[0025] As a preferred embodiment of this utility model, two of the first pressing device 4, the second pressing device 6, and the third pressing device 8 are arranged side by side, so that the downward pressure of the first pressing rod 43, the second pressing rod 63, and the third pressing rod 83 is balanced, stable, and reliable.

[0026] As shown in Figure 2, a first support rod 11 is vertically installed above the front end of the tooling base 1. The first support rod 11 is used to support and press against the lower side of the front edge of the communication housing 10. The first pressure rod 43 is vertically opposite to the first support rod 11. A second support rod 12 is vertically installed above the rear end of the tooling base 1. The second support rod 12 is used to support and press against the lower side of the rear edge of the communication housing 10. The third pressure rod 83 is vertically opposite to the second support rod 12. In this embodiment, the position of the communication housing 10 pressed by the first pressure rod 43 and the third pressure rod 83 is in a suspended state. During the friction welding process, the communication housing 10 will heat up. If there is no support, the suspended pressing position is prone to deformation. This utility model, by setting the first support rod 11 and the second support rod 12, can form a supporting effect and prevent the communication housing 10 from deforming in the suspended pressing position.

[0027] The above description is merely a preferred embodiment of this utility model.
