Description

Technical Field

[0001] The utility model relates to the technical field of tapping devices, in particular to a multi-station tapping device for heat sinks. Background Technique

[0002] A heat sink is a device for dissipating heat from heat-generating electronic components in electrical appliances. It is mostly made of aluminum alloy, brass or bronze in the form of plates, sheets, multi-sheets, etc. For example, a CPU (Central Processing Unit) in a computer requires a relatively large heat sink, and power tubes, line tubes in televisions, and power amplifier tubes in power amplifiers all require heat sinks. Generally, a layer of thermal grease needs to be applied on the contact surface between the electronic component and the heat sink during use, so that the heat generated by the component can be more effectively conducted to the heat sink and then dissipated into the surrounding air through the heat sink.

[0003] After retrieval, a multi-station tapping device (CN219484978U) includes a base, on the upper surface of which a tapping mechanism and a fixing mechanism are respectively installed. The fixing mechanism includes a turntable rotatably installed on the upper surface of the base. A concave box is fixedly connected to the upper surface of the turntable. A sleeve is fixedly connected to the side surface of the concave box. A first spring is fixedly connected to the inner wall of the sleeve. A sliding rod is slidably connected to the inner wall of the sleeve. In the utility model, the settings of the concave box, the sleeve, the first spring, the sliding rod and the pressing plate facilitate the fixing of the box body. Processing can be carried out through the tapping mechanism. At the same time, starting the driving motor can drive the turntable to rotate, thereby adjusting the positions of multiple concave boxes, facilitating the removal of the processed box body and the installation of the box body in advance. At the same time, the settings of the sliding block, the L-shaped block, the second spring and the plugging block can fix the position of the turntable and ensure the stability of the turntable during the processing.

[0004] Due to the small volume of the heat sink, ordinary fixing devices cannot fix the heat sink. At the same time, the volume of the heat sink is small, and when adjusting the position of the heat sink and performing tapping, mechanical adjustment is prone to deviation. In view of this, we propose a multi-station tapping device for heat sinks. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] Please refer to Figures 1 - 3, the utility model provides a multi-station tapping device for heat sinks, which includes a base 1. A support column 2 is fixedly connected to the upper surface of the base 1, and a multi-stage rotary oil cylinder 3 is fixedly connected to the support column 2. In order to facilitate tapping of the heat sink, it can be achieved by fixedly connecting a tapping roller to the output shaft of the multi-stage rotary oil cylinder 3. A fixing mechanism 4 is arranged on the upper surface of the base 1; the fixing mechanism 4 includes: a workbench 41. A cross groove 42 is opened on the upper surface of the workbench 41. A movable block 43 is slidably connected to the inner surface of the cross groove 42. In order to ensure that the movable block 43 can move within the cross groove 42 to adjust the position of the heat sink, thereby facilitating tapping of the heat sink, a first sliding groove 44 is opened on the upper surface of the movable block 43. A motor 45 is fixedly connected to the left surface of the movable block 43. The output end of the motor 45 is fixedly connected to a threaded rod 46. The threaded rod 46 is rotatably connected to the inner surface of the first sliding groove 44. A clamping block 47 is slidably connected to the inner surface of the first sliding groove 44. In order to ensure that the clamping block 47 can stably move on the upper surface of the movable block 43, the clamping block 47 is limited by the opened first sliding groove 44, thereby effectively ensuring the high stability of the clamping block 47. The clamping block 47 is threadedly connected to the threaded rod 46. One end of a first spring 5 is fixedly connected to the inner surface of the cross groove 42, and the other end of the first spring 5 is in contact with the movable block 43. Four groups of first springs 5 are provided, and the four groups of first springs 5 are respectively distributed on the upper, lower, left, and right sides of the inner surface of the first sliding groove 44. In order to ensure that the movable block 43 can be relatively stable without adjustment, the elastic force of the four groups of first springs 5 is used to limit the movable block 43, thereby effectively improving the stability of the movable block 43.

[0027] In this embodiment, through the mutual cooperation of the cross groove 42, the workbench 41, the threaded rod 46, and the clamping block 47, the heat sink is fixed, and at the same time, the heat sink can be adjusted to ensure that the heat sink is more convenient during the tapping process.

[0028] Embodiment Two

[0029] Please refer to Figures 1 - 5, on the basis of the first embodiment, the present utility model provides a technical solution: preferably, a positioning mechanism 6 is provided on the clamping block 47. The positioning mechanism 6 includes: a second chute 61, the front surface of the clamping block 47 is provided with the second chute 61, the left surface of the clamping block 47 is provided with a third chute 62, and the inner surface of the third chute 62 is slidably connected with a slider 63. In order to ensure that the slider 63 is more stable during the sliding process, the slider 63 is limited by the opened third chute 62. At the same time, the cross-sectional shape of the slider 63 is L-shaped, which is convenient for fixing the second spring 64. One end of the second spring 64 is fixedly connected to the lower surface of the slider 63, and the other end of the second spring 64 is fixedly connected to the left surface of the clamping block 47. The second chute 61 communicates with the third chute 62. In order to ensure that the entire positioning mechanism 6 can be linked, through the cooperation of the second chute 61 and the third chute 62 being communicated and the bracket 8, a linkage effect is achieved. A clamping rod 7 is slidably connected to the inner surface of the third chute 62. One end of a bracket 8 is rotatably connected to the front surface of the clamping rod 7, and the other end of the bracket 8 is hinged to the front surface of the slider 63. A T-shaped through groove 9 is opened on the upper surface of the movable block 43, and the inner surface of the T-shaped through groove 9 is slidably connected with the clamping rod 7. In order to facilitate the movement of the clamping rod 7 in the movable block 43, through the opened T-shaped through groove 9, it is ensured that the clamping rod 7 can move along with the clamping block 47 and can also move downward. A horizontal card slot 10 is opened on the inner surface of the cross slot 42, and a vertical card slot 11 is opened on the inner surface of the cross slot 42. The horizontal card slot 10 and the vertical card slot 11 are slidably connected with the clamping rod 7. In order to ensure that the clamping rod 7 can be inserted into the vertical card slot 11 and the horizontal card slot 10, the vertical card slot 11 and the horizontal card slot 10 are of the same size, so as to facilitate the limitation of the movable block 43.

[0030] In this embodiment, through the provided slider 63, bracket 8, clamping rod 7, horizontal card slot 10 and vertical card slot 11, when the clamping block 47 drives the slider 63 to move towards the heat sink and the slider 63 contacts the heat sink, the clamping rod 7 is driven to move downward through the bracket 8 and is clamped into the horizontal card slot 10 or the vertical card slot 11, so as to limit the movable block 43 and ensure the stability of the entire device.

[0031] Working principle: When threading the heat sink, start the motor 45, the motor 45 drives the threaded rod 46 to rotate. After the clamping block 47 clamps the heat sink, start the multi-stage rotary oil cylinder 3 to thread the heat sink. When adjusting the heat sink, the output shaft of the motor 45 drives the threaded rod 46 to rotate in the reverse direction. After loosening the heat sink, move the movable block 43 in the cross slot 42, and then the output shaft of the motor 45 rotates forward to drive the threaded rod 46, so that the clamping block 47 clamps the heat sink again. Before the clamping block 47 contacts the heat sink, the slider 63 contacts the heat sink first. After being extruded by the heat sink, it moves outwards from the clamping block 47. The clamping rod 7 is driven to move downward through the bracket 8. After the clamping rod 7 moves downward and is clamped into the horizontal card slot 10 or the vertical card slot 11, the limitation of the movable block 43 can be realized.
