Description

Technical Field

[0001] This application relates to the field of liquid cooling plate processing technology, and in particular to an adaptive and efficient deburring device for cleaning liquid cooling plates. Background Technology

[0002] Liquid cooling plates are heat dissipation structures commonly used in applications such as new energy vehicle batteries, high-performance computers, and servers that generate significant heat during operation. These plates cool silicon wafers by introducing water or other liquids into the heat sink, thus reducing chip temperature. Liquid cooling plates are also frequently used for heat dissipation in automotive power batteries. In the field of liquid cooling plates for new energy batteries, integrated battery support structures and integrated chassis-type liquid cooling plates are typically manufactured using die-cast aluminum alloys. However, after manufacturing, the holes on the surface of the liquid cooling plate often produce numerous burrs. Existing deburring devices primarily rely on molds passing through the holes in the liquid cooling plate surface for deburring, or on rotary grinding structures for grinding. The former cannot adapt to different hole sizes on the liquid cooling plate surface, requiring mold replacement and resulting in low efficiency. The latter also suffers from the problem of not being able to adapt to different hole sizes, necessitating the replacement of grinding structures of corresponding sizes for adaptation. These issues urgently need to be addressed. Summary of the Invention

[0003] This application proposes an adaptive and efficient deburring device for cleaning liquid-cooled plates, which has the advantage of strong applicability and solves the problem of poor applicability in the prior art.

[0004] To achieve the above objectives, this application adopts the following technical solution: an adaptive and efficient deburring device for removing burrs from liquid cooling plates, comprising:

[0005] Mounting plate, with a motor mounted on its top;

[0006] The main shaft is fixedly mounted on the output shaft of the motor. An upper connecting plate and a driving gear are fixedly mounted on the upper and lower sides of the outer surface of the main shaft, respectively. A lower connecting plate is fixedly connected to the bottom end of the main shaft. A secondary shaft is rotatably mounted inside the upper and lower connecting plates. A driven gear is fixedly mounted on the outer surface of the secondary shaft. A driving gear is fixedly mounted on the outer surface of the main shaft. A transfer mechanism is provided on the outer surface of the main shaft and meshes with the driving gear and the driven gear, respectively.

[0007] A grinding roller is fitted onto the bottom of the outer surface of the sub-shaft.

[0008] Preferably, the transfer mechanism is distributed above and below the drive gear. The transfer mechanism includes a connecting frame one and a connecting frame two movably sleeved on the outer surface of the main shaft. A transfer gear is rotatably installed inside both the connecting frame one and the connecting frame two. The outer surfaces of the transfer gears mesh with the drive gear and the upper connecting plate, respectively. A fixing plate two is fixedly connected to the outer surface of the connecting frame one, and a fixing plate one is fixedly connected to the outer surface of the connecting frame two. A spring is elastically connected between the fixing plate one and the fixing plate two.

[0009] Preferably, the first connecting frame and the second connecting frame are staggered, and the spring is in a compressed state, so that the intermediate gear can always keep in close contact with the driving gear and the driven gear.

[0010] Preferably, the driven gear and the driving gear are arranged in an alternating vertical arrangement, and the length of the intermediate gear is greater than the length of the driving gear and the driven gear, so that the intermediate gear can completely cover the alternating driven gear and the driving gear.

[0011] Preferably, a first set of arc-shaped grooves is provided on the right side of the upper connecting plate, a sliding sleeve is slidably installed inside the first set of arc-shaped grooves, the top end of the sub-shaft is rotatably installed inside the sliding sleeve, and a screw is threadedly installed on the right side of the upper connecting plate, one end of the screw is rotatably installed on the right side of the sliding sleeve.

[0012] Preferably, a second set of arc-shaped grooves is provided on the right side inside the lower connecting plate, and a sliding groove is provided inside the second set of arc-shaped grooves. A limit ring is fixedly installed on the outer surface of the sub-shaft, and the limit ring is slidably engaged inside the sliding groove.

[0013] Preferably, the grinding roller extends into the liquid cooling plate, the surface of the liquid cooling plate has a deep hole, the outer surface of the grinding roller abuts against one side of the inner wall of the deep hole, and the diameter of the grinding roller is smaller than the inner diameter of the deep hole.

[0014] Preferably, the rotation axis of the grinding roller coincides with the axis of the secondary shaft, and the revolution axis of the grinding roller coincides with the axis of the main shaft.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This device has been redesigned, significantly improving its applicability for deburring deep holes on liquid-cooled plate surfaces of different sizes. To achieve this, the device is equipped with a mounting plate to support the motor, main shaft, and sub-shaft. The main shaft provides fixed support for the upper and lower connecting plates, allowing them to rotate with the motor and main shaft. Two sets of arc-shaped grooves inside the lower and upper connecting plates provide rotational support for the sub-shaft and grinding roller, enabling the motor to directly drive the upper and lower connecting plates, sub-shaft, and grinding roller to revolve, directly deburring and grinding the inner wall of the deep hole. A sliding sleeve is rotatably mounted on the top of the sub-shaft and driven and fixed by a screw, allowing the sub-shaft and grinding roller to move relative to the main shaft and adapt to deep holes of different sizes, thus significantly improving the applicability of the device.

[0017] 2. The intermediate transfer mechanism in this device transmits power from the motor and main shaft to the auxiliary shaft, enabling the grinding roller to achieve synchronous and efficient rotation while revolving around the axis of the main shaft. This significantly shortens the actual working time for deburring and improves the device's efficiency. To achieve this, the device has drive gears and driven gears on the outer surfaces of the main shaft and auxiliary shaft, respectively. The intermediate transfer mechanism on the outer surface of the main shaft synchronously meshes the drive gears and driven gears to achieve the traditional function. Specifically, connecting brackets one and two, which are sleeved on the outer surface of the main shaft, provide rotational support for the two sets of intermediate transfer gears, thus using the intermediate transfer gears as the power transfer component. This prevents the outer part of the grinding roller from contacting the inner wall of the deep hole during grinding and deburring, resulting in more uniform wear on the outer surface of the grinding roller and a longer service life.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figures 1-9 This embodiment discloses an adaptive and efficient deburring device for removing burrs from a liquid cooling plate 7, comprising:

[0032] Mounting plate 1, with motor 2 mounted on top of mounting plate 1;

[0033] The main shaft 3 is fixedly installed on the output shaft of the motor 2. The upper connecting plate 8 and the driving gear 4 are fixedly installed on the upper and lower sides of the outer surface of the main shaft 3, respectively. The lower connecting plate 6 is fixedly connected to the bottom end of the main shaft 3. The secondary shaft 9 is rotatably installed inside the upper connecting plate 8 and the lower connecting plate 6. The driven gear 10 is fixedly installed on the outer surface of the secondary shaft 9. The driving gear 4 is fixedly installed on the outer surface of the main shaft 3. The main shaft 3 is provided with a transfer mechanism 5, which meshes with the driving gear 4 and the driven gear 10 respectively.

[0034] A grinding roller 13 is sleeved on the bottom of the outer surface of the secondary shaft 9;

[0035] This device has been redesigned to significantly improve its applicability for deburring deep holes on the surface of liquid-cooled plates 7 of different sizes. To achieve this, the device is equipped with a mounting plate 1 to support the motor 2, main shaft 3, and sub-shaft 9. The main shaft 3 provides fixed support for the upper connecting plate 8 and the lower connecting plate 6, allowing the upper connecting plate 8 and the lower connecting plate 6 to rotate with the motor 2 and the main shaft 3. Then, the sub-shaft 9 and the grinding roller 13 are rotated and supported by two sets of arc-shaped grooves opened inside the lower connecting plate 6 and the upper connecting plate 8. This allows the motor 2 to directly drive the upper connecting plate 8, the lower connecting plate 6, the sub-shaft 9, and the grinding roller 13 to revolve, directly deburring and grinding the inner wall of the deep hole. The sliding sleeve 12 is rotatably mounted on the top of the sub-shaft 9 and driven and fixed by the screw 11, allowing the sub-shaft 9 and the grinding roller 13 to move relative to the main shaft 3 and adapt to deep holes of different sizes, thereby significantly improving the applicability of the device.

[0036] In this embodiment, the transfer mechanism 5 is distributed on the upper and lower sides of the drive gear 4. The transfer mechanism 5 includes a connecting frame 1 51 and a connecting frame 2 52 that are movably sleeved on the outer surface of the main shaft 3. A transfer gear 56 is rotatably installed inside both the connecting frame 1 51 and the connecting frame 2 52. The outer surface of the transfer gear 56 meshes with the drive gear 4 and the upper connecting plate 8 respectively. A fixing plate 2 54 is fixedly connected to the outer surface of the connecting frame 1 51. A fixing plate 1 53 is fixedly connected to the outer surface of the connecting frame 2 52. A spring 55 is elastically connected between the fixing plate 1 53 and the fixing plate 2 54.

[0037] The intermediate transfer mechanism 5 in this device is used to transmit power from the motor 2 and the main shaft 3 to the auxiliary shaft 9, enabling the grinding roller 13 to achieve synchronous and efficient self-rotation when it revolves around the axis of the main shaft 3. This greatly shortens the actual working time of the device for deburring and improves the working efficiency of the device. To achieve this purpose, the device is equipped with a drive gear 4 and a driven gear 10 on the outer surfaces of the main shaft 3 and the auxiliary shaft 9, respectively. The intermediate transfer mechanism 5 on the outer surface of the main shaft 3 is used to synchronously mesh the drive gear 4 and the driven gear 10 to achieve the traditional function. Specifically, the connecting frame 1 51 and the connecting frame 2 52, which are sleeved on the outer surface of the main shaft 3, provide rotational support for the two sets of intermediate transfer gears 56, thereby using the intermediate transfer gears 56 as the power transfer part for transmission. This prevents the outer part of the grinding roller 13 from contacting the inner wall of the deep hole when grinding and deburring, thus making the wear on the outer surface of the grinding roller 13 more uniform and extending its service life.

[0038] In this embodiment, the first connecting frame 51 and the second connecting frame 52 are staggered, and the spring 55 is in a compressed state, so that the intermediate gear 56 can always keep in close contact with the driving gear 4 and the driven gear 10.

[0039] like Figure 1 , Figure 6 and Figure 7 As shown, the relative displacement between the secondary shaft 9 and the main shaft 3 will change, and the position of the intermediate gear 56 will also change. It rotates around the axis of the main shaft 3. In order for the intermediate gear 56 to always be in close contact with the driving gear 4 and the driven gear 10, the spring 55 between the fixing plate 2 54 and the fixing plate 1 53 fixed on the surface of the connecting frame 1 51 and the connecting frame 2 52 generates a reaction force, thereby generating a reaction force between the connecting frame 1 51 and the connecting frame 2 52, so that the intermediate gear 56 can always be in close contact with the driving gear 4 and the driven gear 10.

[0040] In this embodiment, the passive gear 10 and the active gear 4 are arranged in an alternating vertical arrangement. The length of the intermediate gear 56 is greater than the lengths of the active gear 4 and the passive gear 10. The intermediate gear 56 can completely cover the passive gear 10 and the active gear 4 that are arranged in an alternating vertical arrangement.

[0041] like Figure 1 , Figure 6 and Figure 7 As shown, the staggered arrangement of the passive gear 10 and the active gear 4 avoids mechanical motion interference that may occur during their movement, and also maximizes the displacement of the secondary shaft 9 toward the main shaft 3, thereby enhancing the applicability of the device.

[0042] In this embodiment, a first set of arc-shaped grooves is provided on the right side inside the upper connecting plate 8. A sliding sleeve 12 is slidably installed inside the first set of arc-shaped grooves. The top end of the secondary shaft 9 is rotatably installed inside the sliding sleeve 12. A screw 11 is threadedly installed on the right side of the upper connecting plate 8. One end of the screw 11 is rotatably installed on the right side of the sliding sleeve 12.

[0043] like Figure 1 , Figure 6 and Figure 7 As shown, the first set of arc-shaped grooves inside the upper connecting plate 8 is used to provide support for adjusting the position of the secondary shaft 9. Specifically, the screw 11 is threaded onto the side of the upper connecting plate 8. It generates linear displacement by rotating and drives the sliding sleeve 12 and the secondary shaft 9 to move, adjusting the distance between the grinding roller 13 and the axis of the main shaft 3 to adapt to the deep holes on the surface of the liquid cooling plate 7 of different sizes.

[0044] In this embodiment, a second set of arc-shaped grooves is provided on the right side inside the lower connecting plate 6, and a sliding groove 15 is provided inside the second set of arc-shaped grooves. A limiting ring 14 is fixedly installed on the outer surface of the secondary shaft 9, and the limiting ring 14 is slidably engaged inside the sliding groove 15.

[0045] like Figure 1 , Figure 6 and Figure 7As shown, the second set of arc-shaped grooves on the right side inside the lower connecting plate 6 is used to provide sliding support for the sub-shaft 9. By opening a sliding groove 15 inside the second set of arc-shaped grooves, it can slide and adapt to the limiting ring 14 installed on the surface of the sub-shaft 9, thus completing the sliding support for the sub-shaft 9.

[0046] In this embodiment, the grinding roller 13 extends into the liquid cooling plate 7, and a deep hole is formed on the surface of the liquid cooling plate 7. The outer surface of the grinding roller 13 abuts against one side of the inner wall of the deep hole, and the diameter of the grinding roller 13 is smaller than the inner diameter of the deep hole.

[0047] like Figure 4 As shown, the grinding roller 13 rotates around the axis of the main shaft 3 to cover the inner wall of the deep hole on the surface of the liquid cooling plate 7, thereby achieving the basic function of deburring. This design enables the device to adapt to deep holes of different sizes, making it highly adaptable.

[0048] In this embodiment, the rotation axis of the grinding roller 13 coincides with the axis of the secondary shaft 9, and the revolution axis of the grinding roller 13 coincides with the axis of the main shaft 3.

[0049] like Figure 4 As shown, the revolution axis of the grinding roller 13 coincides with the axis of the main shaft 3, and its rotation axis coincides with the axis of the secondary shaft 9. This design enables the grinding roller 13 to achieve axial uniformity during the grinding process, and the combination of rotation and revolution can accelerate the deburring speed of the device, indirectly reducing the actual working time of the device and improving the working efficiency of the device.

[0050] Working principle:

[0051] When the device is in operation, first determine the inner diameter of the deep hole on the surface of the liquid cooling plate 7, then rotate the screw 11 to adjust the position of the sliding sleeve 12 and the auxiliary shaft 9 inside the upper connecting plate 8 so that the distance between the outer surface of the grinding roller 13 away from the main shaft 3 and the axis of the main shaft 3 is adapted to it. In preparation, simply place the outer surface of the grinding roller 13 against one side of the inner wall of the deep hole to determine the revolution grinding axis of the grinding roller 13.

[0052] Then, start motor 2 and drive main shaft 3, drive gear 4, lower connecting plate 6 and upper connecting plate 8 to rotate. At this time, lower connecting plate 6 and upper connecting plate 8 simultaneously drive secondary shaft 9 to revolve around the axis of main shaft 3, and make the outer surface of grinding roller 13 fully cover the inner wall of deep hole, completing the first stage of deburring and grinding operation.

[0053] Then, the driving gear 4 drives the intermediate gear 56 to rotate, and finally transmits the power to the secondary shaft 9 through the driven gear 10, causing the secondary shaft 9 to rotate. The axis of rotation is the axis of the secondary shaft 9 itself. At this time, the grinding roller 13 removes the burrs on the inner wall of the deep hole on the surface of the liquid cooling plate 7 by combining the motion of revolution and rotation. During the rotation of the secondary shaft 9, the secondary shaft 9 is rotatably mounted on the sliding sleeve 12. The screw 11 drives the sliding sleeve 12 and the secondary shaft 9 along the first set of holes on the surface of the upper connecting plate 8 through the threaded installation. The arc-shaped groove moves, changing the distance between the secondary shaft 9, the grinding roller 13, and the main shaft 3, thereby adapting to deep holes of different sizes. The limiting ring 14 is slidably installed inside the slide groove 15, providing limiting sliding support for the secondary shaft 9. When the position of the secondary shaft 9 is adjusted, the connecting frame 1 51 and the connecting frame 2 52 change the included angle between each other through the limiting contact between the driven gear 10 and the intermediate gear 56, while changing the force state of the spring 55, so that the intermediate gear 56 is always in close contact with the outer surface of the driven gear 10 and the driving gear 4.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
