[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 4 As shown, an automatic grinding and deburring fixture according to an embodiment of the present invention includes a base plate 1. A processing mechanism is provided on the top of the base plate 1. The processing mechanism includes: a grinding component, including a support plate 2 connected to the top of the base plate 1 via a lifting component, a support ring 3 fixed to the bottom of the support plate 2 via a set of fixing rods, a disc 4 rotatably connected to the inner wall of the support ring 3, a first sliding groove 5 opened on the disc 4, a first sliding block 6 slidably connected in the first sliding groove 5, a rotating rod 7 rotatably connected to the first sliding block 6 via a first rotating hole, a grinding roller 8 fixedly connected to the rotating rod 7, and a driving component for driving the rotating rod 7 and the disc 4 to rotate at the bottom of the support plate 2; and a positioning component, which is provided on the base plate 1 for positioning the drill bit.
[0025] During operation, the first sliding block 6 can slide within the first sliding groove 5, thereby driving the grinding roller 8 to move simultaneously. The drive assembly drives the rotating rod 7 and the disc 4 to rotate, thus allowing the sliding block to be adjusted according to the diameter of the drill bit for grinding. This solves the problem in the prior art that when grinding drill bits, it is impossible to adjust according to the diameter of the drill bit, and the fixed grinding method is difficult to adapt to drill bits of different diameters, requiring the replacement of grinding equipment, which is inconvenient.
[0026] The lifting assembly includes a vertical plate 9 fixed to the top of the base plate 1. A pair of second sliding grooves 10 are provided on the vertical plate 9. A second sliding block 11 is slidably connected in the second sliding groove 10. An adjusting plate 12 is fixed to the side wall of the second sliding block 11. A first electric push rod 13 is fixed to the side wall of the vertical plate 9. The telescopic end of the first electric push rod 13 is fixed to the bottom of the adjusting plate 12. The side wall of the support plate 2 is fixed to the side wall of the pair of first sliding blocks 6.
[0027] During operation, the first electric actuator 13 drives the adjusting plate 12 to rise and fall, which in turn drives the first and second sliding blocks 11 to rise and fall, thereby raising and lowering the support plate 2 and providing sufficient space for the operator to place the drill bit.
[0028] The drive assembly includes a motor 14 fixed to the bottom of the support plate 2, a drive rod 15 at the output end of the motor 14, the bottom of the drive rod 15 fixed to the top of the disk 4, and a first bevel gear 16 fixed to the drive rod 15.
[0029] An L-shaped block 17 is fixedly connected to the drive rod 15. The vertical end of the L-shaped block 17 is rotatably connected to a second electric push rod 18 through a second rotating hole. The fixed end of the second electric push rod 18 is fixedly connected to a second bevel gear 19, which meshes with the first bevel gear 16.
[0030] A fixing block 20 is fixedly connected to the side wall of the first sliding block 6. The fixing block 20 is rotatably connected to the telescopic end of the electric push rod through the third rotating hole. A third bevel gear 21 is fixedly connected to the telescopic end of the electric push rod. A fourth bevel gear 22 is fixedly connected to the top of the rotating rod 7. The fourth bevel gear 22 meshes with the third bevel gear 21.
[0031] During operation, the drive rod 15 is driven by the motor 14 to rotate, causing the disc 4 to rotate. At the same time, the drive rod 15 drives the second electric push rod 18 to rotate under the transmission of the first bevel gear 16 and the second bevel gear 19. The electric push rod can drive the third bevel gear 21 to rotate, and through the transmission of the fourth bevel gear 22, it can drive the rotating rod 7 to rotate. This allows the disc 4 to drive the grinding roller 8 to rotate around the drill bit surface. Under the adjustment of the second electric push rod 18, the grinding roller 8 can fit against the drill bit surface and rotate to grind, improving applicability and enabling grinding of drill bits of different diameters.
[0032] A third electric actuator 23 is fixedly connected to the bottom of the base plate 1. A circular block 24 is fixedly connected to the telescopic end of the third electric actuator 23. A set of connecting rods 25 are rotatably connected to the circular block 24 through a set of first rotating shafts. A set of third sliding grooves 26 are provided on the base plate 1. A third sliding block 27 is slidably connected in the third sliding grooves 26. The connecting rods 25 are rotatably connected to the bottom of the third sliding block 27 through a second rotating shaft. A rubber block 28 is fixedly connected to the side wall of the third sliding block 27.
[0033] During operation, the circular block 24 can be driven downward by the telescopic end of the third electric actuator 23, which in turn moves the bottom of the connecting rod 25 downward. This allows the top of the connecting rod 25 to pull the third sliding block 27 to move within the third sliding groove 26, thereby positioning the rubber block 28 and clamping it stably. This prevents movement during grinding and avoids the problem that existing positioning and clamping structures cannot clamp the drill bit from all directions.
[0034] Working principle: The first sliding block 6 can slide within the first sliding groove 5, thereby driving the grinding roller 8 to move simultaneously. The drive assembly drives the rotating rod 7 and the disc 4 to rotate, thus allowing the sliding block to be adjusted according to the diameter of the drill bit for grinding. This solves the problem in the prior art that when grinding drill bits, it is impossible to adjust according to the diameter of the drill bit, and the fixed grinding method is difficult to adapt to drill bits of different diameters, requiring the replacement of grinding equipment, which is inconvenient.
[0035] The first electric actuator 13 drives the adjusting plate 12 to rise and fall, which in turn drives the first and second sliding blocks 11 to rise and fall, thus raising and lowering the support plate 2 and providing workers with enough space to place the drill bit.
[0036] The drive rod 15 is driven by the motor 14 to rotate, causing the disc 4 to rotate. At the same time, the drive rod 15 drives the second electric push rod 18 to rotate under the transmission of the first bevel gear 16 and the second bevel gear 19. The electric push rod can drive the third bevel gear 21 to rotate, and through the transmission of the fourth bevel gear 22, it can drive the rotating rod 7 to rotate. This allows the disc 4 to drive the grinding roller 8 to rotate around the drill bit surface. Under the adjustment of the second electric push rod 18, the grinding roller 8 can fit against the drill bit surface and rotate to grind, improving applicability and enabling grinding of drill bits of different diameters.
[0037] By driving the telescopic end of the third electric actuator 23, the circular block 24 can move the bottom of the connecting rod 25 downwards simultaneously, which in turn can pull the top of the connecting rod 25 to move the third sliding block 27 within the third sliding groove 26. This allows the rubber block 28 to position and stably clamp the drill bit, preventing it from moving during grinding and avoiding the problem that existing positioning and clamping structures cannot clamp the drill bit from all directions.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
