Description

Technical Field

[0001] The invention relates to the technical field of deep hole drilling for heat sinks, and in particular to a transformer heat sink installation drilling device. Background Art

[0002] Transformer heat dissipation refers to the dissipation of heat generated inside the transformer to the external environment through the heat sink to ensure the normal operation of the transformer. As a part of the radiator, the heat sink plays a key role in heat dissipation. Drilling holes in the heat sink can increase the heat dissipation area of the heat sink, allowing heat to be dissipated more effectively from the heat sink surface to the air.

[0003] At present, when drilling holes in transformer heat sinks, it is usually necessary to drill deeper holes. This is because deep holes can provide a longer heat conduction path, allowing heat to be transferred deeper into the interior of the heat sink and dissipate heat from multiple levels, thereby improving the overall heat dissipation efficiency. However, the prior art does not have equipment specifically for drilling deep holes in heat sinks. When ordinary equipment is used to drill deep holes, it is easy to cause the fins on the heat sink to deform, bend or crack, thereby affecting the normal use of the heat sink.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0022] Example 1: Reference Figures 1-9 , a transformer heat sink installation and drilling device includes a support platform 1, a heat sink body 106 is placed on the support platform 1, and also includes a slider 2 slidably arranged on the support platform 1, and a drill bit 202 is rotatably arranged on the slider 2; and a first ring 204, a second ring 205 and a third ring 206, the first ring 204 is fixedly arranged on the slider 2, the second ring 205 is slidably arranged on the first ring 204 and the slider 2, the third ring 206 is slidably arranged on the second ring 205, and the drill bit 202 is arranged between the first ring 204, the second ring 205 and the third ring 206; a slide plate 4 is slidably arranged on the end of the support platform 1 away from the slider 2, and a splint 403 is slidably arranged on the slide plate 4, a tripod 3 is fixedly arranged on the support platform 1, and a cross bar 305 is fixedly connected to the tripod 3; an insert block 601 is slidably arranged on the cross bar 305, and two trapezoidal blocks 606 are slidably connected in the insert block 601.

[0023] In this embodiment, when in use, the heat sink body 106 is first placed on the support platform 1, and a limit bar 101 is provided on the support platform 1, which can perform preliminary limiting on the heat sink body 106, and then by controlling the movement of the slider 2, the drill bit 202 can be driven to move to perform drilling operations on the heat sink body 106, and the drill bit 202 is set longer, which can achieve deep hole drilling operations. At the same time, when the slider 2 moves, the third ring 206 will first be pressed against the heat sink body 106 and thus against the position on the heat sink body 106 where holes need to be drilled, to avoid cracks around the area when drilling. As the slider 2 moves, the third ring 206 will slide on the second ring 205, and the second ring 205 will also slide on the slider 2, which will not affect the normal penetration of the drill bit 202, thereby facilitating deep hole drilling operations.

[0024] Before the above-mentioned drilling operation is performed, the movement of the slider 2 will synchronously drive the slide plate 4 located on the other side of the support platform 1 to move, so that the clamping plate 403 first contacts the other end of the heat sink body 106, realizing the clamping operation of the heat sink body 106, thereby making its drilling more stable, and when drilling, the plug 601 on the cross bar 305 will move downward, thereby being inserted between the multiple fins on the heat sink body 106, thereby supporting the multiple fins and preventing the fins on the heat sink body 106 from being deformed during drilling, and two trapezoidal blocks 606 are provided on the plug 601. When in use, the trapezoidal blocks 606 will extend out, thereby further supporting the fins on the heat sink body 106 and preventing them from being deformed, etc. Secondly, when the trapezoidal blocks 606 are retracted into the plug 601, the plug 601 can be easily removed from between the fins, thereby improving the drilling effect and ensuring the subsequent use effect of the heat sink body 106.

Reference Figure 1-Figure 5 Three T-slots 102 are provided on the support platform 1, three first T-blocks 203 are fixedly connected to the bottom of the slider 2, and three second T-blocks 401 are provided at the bottom of the slide 4. The three first T-blocks 203 and the second T-blocks 401 are all slidably connected in the corresponding T-slots 102.

[0026] Reference Figure 1-Figure 5 A motor 103 is provided on the outer wall of the support platform 1, and a screw rod 104 and a limit rod 105 are respectively provided in the T-slot 102. The screw rod 104 is provided at the output end of the motor 103, and the screw rod 104 is rotatably provided in the T-slot 102. The first T-block 203 and the second T-block 401 located in the middle are both threadedly connected to the screw rod 104, and the first T-block 203 and the second T-block 401 located on both sides are both slidingly connected to the limit rod 105. The threads at both ends of the screw rod 104 have opposite rotation directions, and the first T-block 203 and the second T-block 401 are respectively threadedly connected to the two ends of the screw rod 104.

[0027] In this embodiment, when in use, the motor 103 is started to drive the screw rod 104 at the output end to rotate, so that the screw rod 104 drives the first T-block 203 and the second T-block 401 threadedly connected thereto to start moving, and then drives the slider 2 and the slide plate 4 to start moving. The limit rod 105 is provided to make the movement of the slider 2 and the slide plate 4 more stable. It should be noted that the threads at both ends of the screw rod 104 rotate in opposite directions, so the directions of movement of the slider 2 and the slide plate 4 are opposite, that is, the slider 2 can be moved to the left to realize the drilling operation, and at the same time the slide plate 4 can be moved to the right to achieve the effect of clamping and fixing. The motor 103 adopts a forward and reverse motor. When the motor 103 reverses, the slider 2 and the slide plate 4 can be rotated in the opposite direction to achieve automatic resetting.

[0028] A thin rod 207 is fixedly connected to the third ring 206, and a hollow rod 208 is fixedly connected to the second ring 205. The end of the thin rod 207 away from the third ring 206 passes through the second ring 205 and is slidably connected in the hollow rod 208.

[0030] In this embodiment, when the slider 2 moves, the drill bit 202 is driven to rotate by the driving part 201. The driving part 201 can specifically be a motor, etc. After the third ring 206 touches the heat sink body 106, the slider 2 will continue to drive the drill bit 202 to move, so that the drill bit 202 contacts the heat sink body 106 and realizes the drilling operation. At the same time, the third ring 206 will push the thin rod 207 to slide in the hollow rod 208. When the slider 2 and the drill bit 202 continue to move, the second ring 205 will also move, and at the same time, the hollow rod 208 will be driven to slide toward the inside of the slider 2, and the first spring 209 and the second spring 210 will be compressed. On the one hand, it can protect the edge of the drilling position to avoid cracks and the like during drilling.

[0032] When the slider 2 moves to the left, the skateboard 4 will move to the right at the same time, causing the clamping plate 403 to contact the heat sink body 106 first, thereby fixing the heat sink body 106 with the clamping plate 403. During the continuous movement of the skateboard 4, the slide rod 402 will slide on the skateboard 4 and compress the third spring 405, which will not affect the clamping effect. The third spring 405 can provide a buffering effect to avoid jamming. A rubber pad 404 is provided on the outer wall of the clamping plate 403 to protect the heat sink body 106.

[0034] Reference Figure 3 and Figure 6-Figure 8 A first bevel gear 307 is provided on the connecting shaft 302, and a threaded rod 5 is rotatably connected to the cross bar 305. One end of the threaded rod 5 placed in the cross bar 305 is provided with a second bevel gear 501 meshing with the first bevel gear 307.

[0035] In this embodiment, when the motor 103 is started, it can drive the screw rod 104 to rotate, thereby realizing the movement of the slider 2 and the slide plate 4. At the same time, the short shaft 301 is driven to rotate through the first pulley and the first belt 303, thereby driving the connecting shaft 302 to rotate through the second pulley and the second belt 304, and then driving the first bevel gear 307 to rotate, and then driving the threaded rod 5 to rotate through the second bevel gear 501 engaged therewith. When the threaded rod 5 rotates, it will drive the first movable plate 502 threadedly connected thereto to move, and drive the second movable plate 504 to move through the first fixed rod 503, and then drive the second fixed rod 6 and the insert block 601 to move, so that the insert block 601 is inserted between the fins on the heat sink body 106 to support the fins to prevent them from deformation during deep hole drilling operations.

[0036] Reference Figure 9 A cavity 602 is provided in the plug block 601, and one end of the second fixing rod 6 is placed in the cavity 602 and fixedly connected to the limit plate 604.

At this time, the insert block 601 will not move again. Therefore, when the second movable plate 504 moves, it will drive the limit plate 604 to move through the second fixed rod 6, and then drive the cone block 605 to move. The bottom of the cone block 605 is tilted. After it contacts the slope on the trapezoidal block 606, it will push the trapezoidal block 606 to move to both sides, so that the trapezoidal block 606 extends out of the cavity 602, so that it presses against the fin.

At the same time, a sponge pad is also provided on the outer wall of the trapezoidal block 606 to prevent damage to the fin. The inclined surface 608 at the bottom of the plug 601 is to enable it to be better inserted between the fins for limiting.
