[0043] The following describes an embodiment of the multi-face drilling fixture 100 and multi-face drilling equipment of the present invention with reference to the accompanying drawings.

[0044] Reference Figure 1 According to a first aspect embodiment of the present invention, a multi-faceted drilling fixture 100 is used for drilling 120 holes in a heat sink 220. The heat sink 220 has two opposing first unmachined surfaces 221 and second unmachined surfaces 222. The heat sink 220 also has multiple machined surfaces distinct from the first unmachined surfaces 221 and second unmachined surfaces 222. The multi-faceted drilling fixture 100 includes a fixing frame 250, a mold 110, a support platform 230, and a first driver 200. The mold 110 is fixed to the fixing frame 250 and has a positioning part 150 and multiple sides 130. Each side 130 defines a receiving groove 160. At least two sides 130 are provided with drill holes 120, and the positions of the sides 130 with drill holes 120 correspond one-to-one with the positions of the machined surfaces. The support platform 230 is used to support the heat sink 220. The first driver 200 includes a first output terminal capable of reciprocating in a horizontal direction. The first output terminal abuts against a first unmachined surface 221, driving the heat sink 220 to move in a first direction so that the second unmachined surface 222 abuts against the positioning part 150. The multi-faceted drilling fixture 100 of this embodiment can improve the clamping efficiency of the heat sink 220.

[0045] Specifically, the fixed frame 250 and the mold 110 can be fixedly connected by welding, or they can be detachably connected by bolts or other pre-tightening components to facilitate the replacement of the mold 110 and improve the applicability of the multi-faceted drilling fixture 100. The positioning part 150 can be set as a positioning pin, which is inserted into a pin hole on the positioning frame to connect the positioning part 150 and the positioning frame; the positioning part 150 can also be fixed to the end of the fixed frame 250 or the inner surface of the receiving groove 160 by bolts or other pre-tightening components; the positioning part 150 can also be integrally formed with the mold 110. The bearing platform 230 can be integral with the fixed frame 250 or a support block fixed to the fixed frame 250, and the length of the bearing platform 230 can be adapted to the length of the receiving groove 160 or greater than the length of the receiving groove 160. The first driver 200 can be a linear drive motor or a cylinder.

[0046] After the operator pushes the radiator 220 directly into the receiving groove 160, or places the radiator 220 on the support platform 230 and aligns it with the receiving groove 160 along the first direction, the operator controls the first output end of the first driver 200 to move closer to the radiator 220 along the first direction. When the first output end of the first driver 200 abuts against the first non-machined surface 221 of the radiator 220, the radiator 220 gradually moves closer to the positioning part 150 under the drive of the first driver 200. When the second non-machined surface 222 of the radiator 220 abuts against the positioning part 150, the radiator 220 is clamped and fixed between the positioning part 150 and the first output end of the first driver 200, thus fixing the radiator 220 in the fixing groove. The positioning part 150 provides positioning guidance for the radiator 220, realizing rapid positioning between the radiator 220 and the mold 110. Subsequently, multi-face drilling of the radiator 220 can be achieved through the drilling holes 120 on the side 130. By using the first driver 200 to push and support the heat sink 220 and the positioning part 150 to cooperate, the heat sink 220 is quickly positioned and fixed on the mold 110.

[0047] Furthermore, refer to Figure 2 The multi-faceted drilling fixture 100 also includes a drill bushing 300, which is installed on the mold 110, and the position of the drill bushing 300 corresponds to the position of the drill hole 120. The drill bushing 300 can be a fixed drill bushing 300 or a quick-change drill bushing 300. By setting the drill bushing 300, the drill bit can be positioned and guided for machining, improving the machining accuracy and stability of the drill bit, reducing the probability of the drill bit damaging the mold 110, and extending the service life of the mold 110.

[0048] Reference Figure 2According to some embodiments of the present invention, the multi-faceted drilling fixture 100 further includes a second driver 240. The second driver 240 includes a second output end capable of reciprocating in a horizontal direction. The second driver 240 is disposed opposite to the first driver 200. The second output end can abut against the second non-machined surface 222, driving the heat sink 220 to move in a second direction, which is opposite to the first direction. The arrangement of the second driver 240 can improve material handling efficiency.

[0049] Specifically, the second driver 240 can be selected as a linear drive motor or a cylinder. After the radiator 220 completes the drilling operation, the first output end of the first driver 200 is first controlled to retract to the initial state, reserving sufficient movement space for the radiator 220 to move out of the receiving groove 160, and preventing interference between the first output end of the first driver 200 and the radiator 220. Then, the second output end of the second driver 240 is controlled to abut against the second non-machined surface 222, so as to drive the radiator 220 to slide out of the receiving groove 160 in the second direction, completing the material removal operation of the radiator 220. Compared with the manual material removal method, using the second driver 240 to remove the material reduces the difficulty of removing the radiator 220, thereby improving the material removal efficiency of the radiator 220, and can also ensure sufficient driving force to push the radiator 220 when dealing with a heavy radiator 220.

[0050] Reference Figure 2 According to some embodiments of the present invention, the multi-face drilling fixture 100 further includes a third driver 310. The third driver 310 includes a third output end capable of reciprocating in a vertical direction. The third output end is connected to the support platform and is used to drive the support platform 230 to move in a vertical direction, so that the heat sink 220 moves in a vertical direction within the receiving groove 160. The provision of the third driver 310 improves the positioning accuracy of the heat sink 220 in the vertical direction.

[0051] Specifically, the third driver 310 can be selected as a linear drive motor or a cylinder. The third driver 310 can be installed on the fixed frame 250 or directly on the ground. The fixed frame 250 is provided with a sliding hole 320, which provides movement space for the third output end of the third driver 310 to move in the vertical direction. The support platform 230 is fixed to the third output end of the third driver 310.

[0052] By setting the third actuator 310, the heat sink 220 can be adjusted vertically within the receiving slot 160, thereby adjusting the drilling position of the heat sink 220 in the vertical direction. When the heat sink 220 itself has a certain dimensional error in the vertical direction, or when dealing with heat sinks 220 with different vertical dimensions, adjusting the vertical position of the heat sink 220 through the third actuator 310 can ensure that the drilling position is in the correct position without the need to change the mold or add shims, thus improving the positioning accuracy and applicability of the multi-face drilling fixture 100 in the vertical direction.

[0053] After processing, a second driver 240 can be set up to perform material handling operation on the radiator 220. By combining the second driver 240 and the third driver 310, the positioning accuracy of the multi-face drilling fixture 100 is improved, while the production efficiency of the radiator 220 is also improved.

[0054] Reference Figure 3 According to a further embodiment of the present invention, the fixing frame 250 is provided with a sliding groove 340, the channel of the sliding groove 340 being arranged along a first direction. The third output end of the third driver 310 can drive the bearing platform 230 to move vertically along the sliding groove 340, so that the heat sink 220 can enter or exit the sliding groove 340 vertically. The provision of the sliding groove 340 makes the overall structure of the multi-faceted drilling fixture 100 more compact.

[0055] Specifically, the third actuator 310 is installed at the bottom of the sliding groove 340. The sliding groove 340 allows the radiator 220 to enter the receiving groove 160 vertically. When drilling multiple holes in the radiator 220, the operator places the radiator 220 on the support platform 230 and aligns the radiator 220 with the opening of the receiving groove 160 vertically. Then, the third actuator 310 is controlled to drive the support platform 230 closer to the mold 110, thereby allowing the radiator 220 to enter the receiving groove 160. When the radiator 220 reaches the designated processing position vertically, the third actuator 310 is stopped, ensuring the radiator 220 is in the correct processing position. Then, the second actuator 240 is controlled to push the radiator 220 against the positioning part 150, thereby achieving horizontal positioning and pre-tightening of the radiator 220 within the mold 110, thus completing the positioning and fixing operation of the radiator 220.

[0056] Compared to pushing the radiator 220 into the receiving groove 160 in the horizontal direction, pushing the radiator 220 into the receiving groove 160 in the vertical direction can make better use of the three-dimensional space of the multi-face drilling fixture 100. Moreover, when unloading the radiator 220 after processing, it is not necessary to reserve a large distance for the retraction of the first output end of the first driver 200. The first driver 200 can be set closer to the mold 110, thereby making the overall structure of the multi-face drilling fixture 100 more compact and reducing the floor space occupied by the multi-face drilling fixture 100.

[0057] Reference Figure 3 According to a further embodiment of the present invention, the sliding groove 340 is disposed through the first direction, and the multi-faceted drilling fixture 100 further includes a fourth driver 330. The fourth driver 330 includes a fourth output end capable of reciprocating in a horizontal direction. The fourth output end is used to drive the heat sink 220 to move within the sliding groove 340 when the heat sink 220 is located within the sliding groove 340, thereby causing the heat sink 220 to disengage from the sliding groove 340 along the first direction or along a second direction, the second direction being opposite to the first direction. The arrangement of the fourth driver 330 can improve the material handling efficiency of the heat sink 220.

[0058] Specifically, the fourth actuator 330 can be selected as a linear drive motor or a cylinder. When the fourth actuator 330 is positioned on the second direction side of the mounting bracket 250, after the radiator 220 completes the drilling operation, the third actuator 310 is controlled to drive the radiator 220 into the sliding groove 340. When the radiator 220 moves to the point where its projection in the horizontal direction no longer overlaps with that of the positioning part 150, the movement of the radiator 220 stops. Then, the fourth actuator 330 is controlled to push the radiator 220 along the first direction to push it away from the sliding groove 340, thereby facilitating subsequent handling of the radiator 220 and improving its handling efficiency. At the adjacent position in the first direction of the fixed frame 250, a receiving platform can be set to receive the radiator 220, so as to facilitate the workers to pick up the radiator 220 later. After the radiator with holes is pushed out by the fourth drive 330, the workers can first place the radiator without holes and then retrieve the radiator with holes, thereby making the production process of the radiator 220 more compact and improving the production efficiency of the radiator 220.

[0059] In another embodiment, when the fourth actuator 330 is positioned on one side of the fixed frame 250 in the first direction, the radiator 220 needs to move vertically until its projection in the horizontal direction no longer overlaps with that of the first actuator 200 before stopping. Then, the fourth actuator 330 is controlled to push the radiator 220 in the second direction, thereby pushing it away from the sliding groove 340. This facilitates subsequent handling of the radiator 220 and improves its handling efficiency. The receiving platform, transfer car, and conveyor belt are positioned adjacent to each other in the second direction of the fixed frame 250 to match the position where the radiator 220 disengages from the sliding groove 340.

[0060] Reference Figure 1 According to some embodiments of the present invention, the side portion 130 includes a first side portion 132, a second side portion 131, and a third side portion 133. Each of the first side portion 132, second side portion 131, and third side portion 133 is provided with a drilled hole 120. The first side portion 132 is disposed opposite to the supporting platform 230. The second side portion 131 and the third side portion 133 are connected to the same side of the first side portion 132, and are disposed opposite to each other. The second side portion 131 is fixed to the fixing frame 250, and the third side portion 133 is fixed to the fixing frame 250. The multi-face drilling fixture 100 of this embodiment can perform three-sided drilling on the heat sink 220.

[0061] Specifically, the second side 131 and the fixing frame 250 can be fixedly connected by welding or by using bolts or other pre-tightening components for a detachable connection, facilitating the replacement of the mold 110. The fixing method between the third side 133 and the fixing frame 250 is the same as that between the second side 131 and the fixing frame 250. The second side 131 and the first side 132 can be integrally formed, or the second side 131 can be fixed to the first side 132 by welding or using bolts or other pre-tightening components. The connection method between the third side 133 and the first side 132 is the same as that between the second side 131 and the first side 132.

[0062] The radiator 220 has three adjacent machined surfaces, which are respectively opposite to the first side 132, the second side 131, and the third side 133. After the radiator 220 is pushed into the receiving groove 160 along the first direction and positioned and pre-tightened by the first driver 200, the subsequent drilling of the three sides of the radiator 220 can be performed.

[0063] Reference Figure 4According to some embodiments of the present invention, the mold 110 is further provided with a guide portion 400, which is disposed on the inner surface of the receiving groove 160. The guide portion 400 is used to guide the heat sink 220 to slide into the receiving groove 160. The provision of the guide portion 400 reduces the probability that the heat sink 220 will be unable to enter the receiving groove 160 due to interference with the outer surface of the mold 110.

[0064] Specifically, the guide part 400 can be located at the opening of the radiator 220 entering the receiving groove 160 in the first direction, or at the opening of the radiator 220 entering the receiving groove 160 in the vertical direction. The guide part 400 is an inclined surface on the inner surface of the receiving groove 160, which is used to make the width of the channel of the receiving groove 160 gradually increase along the direction close to the opening of the receiving groove 160. This allows the radiator 220 to be guided into the receiving groove 160 along the inclined direction after contacting the inclined surface, thereby reducing the probability that the radiator 220 will interfere with the outer surface of the mold 110 and fail to enter the receiving groove 160, and also reducing the accuracy requirements for the operator to align the radiator 220 with the receiving groove 160.

[0065] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, a multi-faceted drilling fixture 100 is provided. A heat sink 220 is provided with multiple fins arranged side-by-side and spaced apart. Along a direction perpendicular to the fin arrangement, a first unmachined surface 221 and a second unmachined surface 222 are respectively provided at opposite ends of the heat sink 220. The multi-faceted drilling fixture 100 also includes a push plate 210. The length of the push plate 210 along the fin arrangement direction is greater than the distance between adjacent fins. The push plate 210 is fixed to the first output end of a first driver 200 and is used to contact and abut against the first unmachined surface 221. The push plate 210 reduces the possibility of damage to the fins of the heat sink 220.

[0066] Specifically, the push plate 210 is fixedly connected to the first output end of the first driver 200 by welding or bolts or other pre-tightening components. When the unprocessed surface of the heat sink 220 is an end face perpendicular to the fin arrangement direction, the unprocessed surface has multiple narrow faces of vertically or horizontally distributed fins, with a certain gap between adjacent fins. Since the contact area between the first output end of the first driver 200 and the unprocessed surface is small, when the first output end of the first driver 200 directly abuts against the narrow face of the heat sink fin, it is easy to damage the heat sink fin by abutting against a single heat sink fin. By providing the push plate 210, and the length of the push plate 210 along the fin arrangement direction is greater than the distance between adjacent fins, the contact area between the first driver 200 and the unprocessed surface is increased, thereby ensuring that when the push plate 210 contacts the unprocessed surface, it simultaneously abuts against the ends of multiple fins, making the driving force of the first driver 200 applied to the heat sink 220 more uniform, thereby reducing the possibility of damage to the fins of the heat sink 220.

[0067] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the multi-faceted drilling fixture 100 further includes a limiting boss 140, which is located on the side portion 130 where the drill hole 120 is provided, and is disposed on the inner surface of the receiving groove 160. The provision of the limiting boss 140 can ensure the smooth progress of the drilling operation.

[0068] Specifically, the limiting boss 140 can be a protrusion fixed to the inner surface of the receiving groove 160 by welding or pre-tightening with bolts or other pre-tightening components, or it can be a protrusion formed integrally with the mold 110 on the inner surface of the receiving groove 160. During drilling of the radiator 220, drill chips and other waste materials will continuously be discharged from the corresponding drill hole 120. If the waste materials cannot be discharged normally, the drill bit may jam or deviate, affecting the drilling operation. By setting the limiting boss 140, the thickness of the limiting boss 140 creates a certain gap between the machined surface of the radiator 220 and the inner surface of the receiving groove 160, ensuring the discharge of waste materials. Furthermore, the limiting boss 140 plays a positioning role for the heat sink 220. Each limiting boss 140 controls the distance between each machined surface of the heat sink 220 and the corresponding side 130 within a certain range, preventing a situation where one machined surface is smaller than the corresponding side 130 and the other machined surface is larger than the corresponding side 130. This would affect the accuracy of subsequent drilling operations, and if such a problem occurs, it would be difficult for the operator to adjust, thus affecting processing efficiency.

[0069] Furthermore, the length direction of the limiting boss 140 is set along the first direction, and the limiting boss 140 extends from one slot in the receiving groove 160 in the first direction to another slot in the receiving groove 160 in the first direction. By setting the length direction and the extension length of the limiting boss 140, the limiting boss 140 continuously limits the movement of the heat sink 220 as it enters the receiving groove 160 along the first direction until it abuts against the positioning part 150, maintaining the distance between the heat sink 220 and each side part 130, thereby ensuring the positioning between the heat sink 220 and the mold 110.

[0070] The multi-face drilling apparatus according to a second aspect embodiment of the present invention includes the multi-face drilling fixture 100 of the first aspect embodiment of the present invention, and further includes a plurality of drilling devices, each drilling device being positioned corresponding to a side portion 130 on which a hole 120 is provided, and the drilling devices being used to drill holes in the heat sink 220. By applying the multi-face drilling fixture 100 of the first aspect embodiment of the present invention, the clamping efficiency of the heat sink 220 can be improved.

[0071] The drilling system according to a third aspect embodiment of the present invention includes the multi-face drilling apparatus of the second aspect embodiment of the present invention, and further includes a third driver 310, a fourth driver 330, and a transfer device. The fixing frame 250 is provided with a sliding groove 340, which is disposed through a first direction. The provision of the transfer device can improve the processing continuity of the drilling system.

[0072] Specifically, the transfer device can be a transfer car or a conveyor belt. The fourth drive 330 pushes the radiator after drilling directly onto the transfer device along the first or second direction. The transfer device then transfers the radiator after drilling to the next workstation for the next process, which improves the processing continuity of the drilling system and thus improves the production efficiency of the radiator 220.

[0073] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
