Description

Technical Field

[0001] This invention relates to the field of keyboard steel plate processing equipment, specifically to a deburring device for a laptop keyboard steel plate. Background Technology

[0002] When manufacturing a laptop, a keyboard needs to be installed inside the laptop. The keyboard helps with typing practice. During keyboard manufacturing, the keyboard contains keyboard buttons. During the production process, the buttons need to be precisely installed on a steel plate. When producing the keyboard steel plate, it needs to be shaped. After shaping, burrs will be generated on the keyboard steel plate. A deburring device is needed to clean the burrs on the outside of the keyboard steel plate.

[0003] In the deburring device for keyboard steel plates, holes need to be made in the keyboard steel plate. The holes are located inside the steel plate, and the deburring device is difficult to move into the inside of the holes. Therefore, when deburring the inside of the holes in the keyboard steel plate, the position of the deburring device needs to be adjusted, which increases the processing steps and reduces work efficiency. To address this, we propose a deburring device for keyboard steel plates of laptops. Summary of the Invention

[0004] To address the shortcomings of existing deburring devices for laptop keyboard steel plates, this invention provides a deburring device for laptop keyboard steel plates. A grinding wheel mounting sleeve is provided between two sets of grinding wheels. The grinding wheels can remove burrs from the outer surface of the steel plate, and the grinding wheel mounting sleeve can extend into the interior of the holes in the steel plate. This increases the efficiency of removing burrs from the steel plate and solves the problems mentioned in the background art.

[0005] This invention provides the following technical solution: a deburring device for a laptop keyboard steel plate, comprising a first clamping plate, a second clamping plate mounted on the upper end of the first clamping plate, a support frame fixedly connected to the upper part of the side of the first clamping plate, a threaded rod internally threaded to the side of the support frame, a threaded rod limiting frame mounted externally to the threaded rod, a connecting post provided on the upper part of the threaded rod limiting frame, a plurality of sets of first gears and first auxiliary gears sequentially mounted between the first clamping plate and the second clamping plate, a plurality of grinding wheels fixedly connected to the lower end of the first gears, a first helical gear fixedly connected to the upper part of the first auxiliary gears, and a plurality of sets of second gears and... A second auxiliary gear is fixedly connected to its upper end with a third helical gear. A first rotating rod and a second rotating rod are sequentially installed on both sides of the upper end of the second clamping plate. A second helical gear is fixedly connected to the outside of the first rotating rod, and a fourth helical gear is fixedly connected to the outside of the second rotating rod. A third gear and a fourth gear are sequentially fixedly connected to the sides of the first rotating rod and the second rotating rod. A rack chain is sleeved on the outside of the third gear and the fourth gear. A grinding wheel mounting sleeve is fixedly connected to the lower part of the second gear. A second grinding wheel is movably sleeved on the outer side of the lower part of the grinding wheel mounting sleeve. A spring is installed between the grinding wheel mounting sleeve and the second grinding wheel. A spherical ball is installed inside the lower end of the second grinding wheel.

[0006] Preferably, a hydraulic telescopic device is installed at the upper end of the connecting column, and a motor is installed on the side of the threaded rod.

[0007] Preferably, the grinding wheel is installed in three rows at the lower end of the first clamping plate, and a set of first auxiliary gears is installed between the two sets of first gears.

[0008] Preferably, the first auxiliary gear and the first gear are clamped between the first clamping plate and the second clamping plate, and the grinding wheel mounting sleeve is installed between the two rows of grinding wheels.

[0009] Preferably, the second helical gear is meshed with the first helical gear, and the fourth helical gear is meshed with the third helical gear.

[0010] Preferably, the external parts of both sets of third and fourth gears are meshed with the rack and pinion chain, and a motor is mounted on the external part of one set of third gears.

[0011] Preferably, the lower end of the grinding wheel mounting sleeve is diamond-shaped, and the second grinding wheel extends to the lower end of the grinding wheel.

[0012] Preferably, the spherical ball bearing is spherical, and the middle part of the grinding wheel mounting sleeve is clamped between the first clamping plate and the second clamping plate.

[0013] Preferably, brushes are installed on both the outer surface and the lower part of the second grinding wheel.

[0014] Compared with existing deburring devices for laptop keyboard plates, the present invention has the following advantages:

[0015] 1. The deburring device for the keyboard steel plate of this laptop computer is designed by placing a grinding wheel mounting sleeve between two rows of grinding wheels. When the grinding wheels grind and deburr the upper part of the steel plate, the second grinding wheel can extend into the interior of the holes in the steel plate, thereby increasing the deburring effect of the steel plate.

[0016] 2. The deburring device for the keyboard steel plate of this laptop computer is activated by starting a motor mounted on the outside of the third gear. The motor drives the third gear to rotate, and through the auxiliary transmission of the rack and pinion chain, it can drive the third gear and the fourth gear to rotate synchronously. The third gear and the fourth gear drive the second helical gear and the fourth helical gear to rotate, and the second helical gear and the fourth helical gear drive the first helical gear and the third helical gear to rotate. That is, according to the linkage relationship, multiple sets of grinding wheels and grinding wheel mounting sleeves can be driven to rotate synchronously.

[0017] 3. The deburring device for the keyboard steel plate of this laptop computer has a second grinding wheel sleeved on the outside of the grinding wheel mounting sleeve. The grinding wheel mounting sleeve can drive the second grinding wheel to rotate, and at the same time, the spring provides elastic kinetic energy for the second grinding wheel to move downward. When the second grinding wheel passes through the inside of the hole in the plate, under the action of the spring elasticity, it can be pushed to move the second grinding wheel into the hole. At the same time, as the second grinding wheel continues to move, it can be moved out of the hole by the rolling of the ball bearing. That is, when removing burrs from the hole in the plate, it is convenient to move the deburring device into the hole, increasing the convenience of burr cleaning. Attached Figure Description

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A deburring device for a laptop keyboard steel plate includes a first clamping plate 1, a second clamping plate 2 mounted on the upper end of the first clamping plate 1, the second clamping plate 2 defining the positions of a first gear 7 and a first auxiliary gear 8, a support frame 3 fixedly connected to the upper part of the side of the first clamping plate 1, the support frame 3 defining the position of a threaded rod 4, the threaded rod 4 being internally threadedly connected to the side of the support frame 3, the threaded rod 4 controlling the overall forward and backward movement of the support frame 3, a threaded rod limiting frame 5 mounted on the outside of the threaded rod 4, and a connecting post 6 provided on the upper part of the threaded rod limiting frame 5. Installed on a telescopic device, the telescopic device controls the overall vertical movement of the first clamping plate 1. Multiple sets of first gears 7 and first auxiliary gears 8 are sequentially installed between the first clamping plate 1 and the second clamping plate 2. The first auxiliary gears 8 drive the first gears 7 to rotate. Multiple sets of grinding wheels 9 are fixedly connected to the lower end of the first gears 7. When the grinding wheels 9 rotate, they can deburr the exterior of the steel plate. A first helical gear 10 is fixedly connected to the upper part of the first auxiliary gear 8. Multiple sets of second gears 11 and second auxiliary gears 12 are sequentially installed on the upper part of the second clamping plate 2. Wheel 12 drives the grinding wheel mounting sleeve 21 to rotate. A third helical gear 15 is fixedly connected to the upper end of the second auxiliary gear 12. The third helical gear 15 meshes with a fourth helical gear 17, which can drive the third helical gear 15 to rotate. A first rotating rod 13 and a second rotating rod 16 are sequentially installed on both sides of the upper end of the second clamping plate 2. A second helical gear 14 is fixedly connected to the outside of the first rotating rod 13, and a fourth helical gear 17 is fixedly connected to the outside of the second rotating rod 16. A third gear 18 and a fourth gear 19 are sequentially fixedly connected to the sides of the first rotating rod 13 and the second rotating rod 16. A rack chain 20 is sleeved on the outside of gear 18 and fourth gear 19. The rack chain 20 drives the third gear 18 and fourth gear 19 to rotate synchronously. A grinding wheel mounting sleeve 21 is fixedly connected to the lower part of the second gear 11. A second grinding wheel 22 is movably sleeved on the outer side of the lower part of the grinding wheel mounting sleeve 21. When the second grinding wheel 22 rotates, it can grind the burrs inside the hole. A spring 23 is installed between the grinding wheel mounting sleeve 21 and the second grinding wheel 22. The spring 23 pushes the second grinding wheel 22 to move downward. A spherical ball bearing 24 is installed inside the lower end of the second grinding wheel 22.

[0028] Please see Figure 1 A hydraulic telescopic device is installed at the upper end of the connecting column 6, and a motor is installed on the side of the threaded rod 4. The hydraulic telescopic device can control the overall up and down movement of the assembly, making it easier to drive the deburring device to contact the keyboard steel plate. At the same time, the motor installed on the side of the threaded rod 4 controls the movement of the support frame 3. During the movement of the support frame 3, the support frame 3 can drive the deburring device to move on the keyboard steel plate, so as to continuously polish the keyboard steel plate.

[0029] Please see Figure 3 The grinding wheels 9 are installed in three rows at the lower end of the first clamping plate 1. A set of first auxiliary gears 8 is installed between the two sets of first gears 7. The grinding wheels 9 are installed in three rows at the lower end of the first clamping plate 1. The three rows of grinding wheels 9 can grind the front of the keyboard steel plate in sequence, which increases the convenience of cleaning the burrs on the outside of the keyboard steel plate. A set of first auxiliary gears 8 is installed between every two sets of first gears 7. The first auxiliary gears 8 drive the two adjacent sets of grinding wheels 9 to rotate synchronously.

[0030] Please see Figure 3 The first auxiliary gear 8 and the first gear 7 are clamped between the first clamping plate 1 and the second clamping plate 2. The grinding wheel mounting sleeve 21 is installed between the two rows of grinding wheels 9. The first auxiliary gear 8 and the first gear 7 are clamped between the first clamping plate 1 and the second clamping plate 2. The first clamping plate 1 and the second clamping plate 2 limit the position of the first auxiliary gear 8 and the first gear 7. At the same time, the grinding wheel mounting sleeve 21 is installed between the two rows of grinding wheels 9. That is, the grinding wheels 9 can deburr the upper part of the keyboard steel plate, and the grinding wheel mounting sleeve 21 can deburr the opening formed in the middle of the keyboard steel plate.

[0031] Please see Figure 2 and Figure 6 The second helical gear 14 is meshed with the first helical gear 10, and the fourth helical gear 17 and the third helical gear 15 are meshed with each other. When the second helical gear 14 rotates, it drives the first helical gear 10 to rotate synchronously. At the same time, when the fourth helical gear 17 rotates, it drives the third helical gear 15 to rotate. During the rotation of the second helical gear 14 and the fourth helical gear 17, the second helical gear 14 and the fourth helical gear 17 drive multiple sets of grinding wheels 9 and grinding wheel mounting sleeves 21 to rotate.

[0032] Please see Figure 6 Both sets of third gears 18 and fourth gears 19 are externally meshed with rack and pinion chain 20. A motor is installed on the outside of one set of third gears 18. By starting the motor installed on the outside of one set of third gears 18, the motor drives the third gear 18 to rotate. At the same time, rack and pinion chain 20 is sleeved on the outside of the third gears 18 and fourth gears 19, and rack and pinion chain 20 drives the third gears 18 and fourth gears 19 to rotate synchronously.

[0033] Please see Figure 7The lower end of the grinding wheel mounting sleeve 21 is diamond-shaped. The second grinding wheel 22 extends to the lower end of the grinding wheel 9. Since the lower end of the grinding wheel mounting sleeve 21 is diamond-shaped, when the third helical gear 15 drives the grinding wheel mounting sleeve 21 to rotate, the grinding wheel mounting sleeve 21 drives the second grinding wheel 22 to rotate synchronously. At the same time, since a spring 23 is installed between the second grinding wheel 22 and the grinding wheel mounting sleeve 21, the spring 23 drives the second grinding wheel 22 to extend and retract elastically up and down. Depending on the size of the groove opened inside the keyboard steel plate, the second grinding wheel 22 can be driven to extend to different depths inside the hole.

[0034] Please see Figure 7 The spherical ball bearing 24 is spherical, and the middle part of the grinding wheel mounting sleeve 21 is clamped between the first clamping plate 1 and the second clamping plate 2. The spherical ball bearing 24 is spherical on the outside. When the grinding wheel mounting sleeve 21 extends to the upper part of the steel plate, the spherical ball bearing 24 moves between the steel plate and the steel plate, so as to avoid scratching the outside of the steel plate when the spherical ball bearing 24 moves on the steel plate.

[0035] Please see Figure 7 Brushes are installed on the outside of the second grinding wheel 22 and the lower part of the grinding wheel 9. When the grinding wheel 9 and the second grinding wheel 22 rotate, they can grind the burrs on the outside of the keyboard steel plate they are in contact with.

[0036] Working principle: In use, the connecting column 6 is installed on the hydraulic telescopic device, the keyboard steel plate is placed under the support frame 3, and the support frame 3 is controlled to move downward. The grinding wheel 9 remains in contact with the keyboard steel plate. At the same time, the motor installed on the outside of the third gear 18 is started. The motor drives the third gear 18 to rotate. The rack chain 20 drives the third gear 18 and the fourth gear 19 to rotate synchronously. At the same time, it drives the second helical gear 14 and the fourth helical gear 17 to rotate. The second helical gear 14 and the fourth helical gear 17 drive the first helical gear 10 and the third helical gear 15 to rotate in sequence. Under the auxiliary transmission of the first auxiliary gear 8 and the second auxiliary gear 12, the grinding wheel 9 and the second grinding wheel 22 rotate. The second grinding wheel 22 can extend into the interior of the hole. The grinding wheel 9 and the second grinding wheel 22 can simultaneously remove burrs contained on the outside of the steel plate and inside the hole, thereby increasing the convenience of burr cleaning.
