Before use, the fixing plate is installed at the desired position, and then the power of the electric telescopic rod is turned on. At this time, the electric telescopic rod is extended, and the piston plate 2 is driven to slide along the inner wall of the fixing cylinder by pushing the bracket. When the piston plate 2 reaches the outermost edge, the piston plate 1 is driven to slide along the inner wall of the hydraulic box 1 through the fixing cylinder, forcing the liquid inside the hydraulic box 1 to enter the hydraulic telescopic rod 1 through the circulation port, forcing the multiple hydraulic telescopic rods 1 to extend, so that the other ends of the multiple hydraulic telescopic rods 1 are in contact with the outer wall of the steering knuckle.

[0021] (4) The present invention utilizes the characteristic that the above-mentioned pushing bracket drives the piston plate 2 to slide inwardly along the fixed cylinder, and a control component is arranged inside the device. When the piston plate 2 drives the pushing bracket to move through the sliding cylinder, the pushing bracket contacts the side wall of the hollow plate, and as the piston plate 2 continues to move laterally, the spring 2 will deform and accumulate mechanical power; and when the piston plate 1 moves laterally to squeeze the liquid inside the hydraulic box 1, after the multiple hydraulic telescopic rods 1 complete the clamping, the continued transverse movement of the piston plate 1 will force a high-pressure environment to form inside the hydraulic box 1, and the high-pressure force will act on the piston square plate, forcing the piston square plate to slide along the inner wall of the hydraulic groove. At this time, the liquid inside the hydraulic groove enters the hydraulic telescopic rod 3 through the transmission pipe, and the extended The hydraulic telescopic rod three will force the sliding baffle to move away from the limiting hole, so that the sliding baffle loses the restriction on the sliding ring. At this time, the spring two will release the mechanical power, forcing the pushing frame to move outward along the inner wall of the sliding cylinder. The outward-moving pushing frame will force the sliding ring to slide outward along the outer wall of the sliding ring plate through the hollow plate. The outward-moving hollow plate will block the flow port, cutting off the flow path between the hydraulic box one and several hydraulic telescopic rods one.

When the piston plate 24 reaches the outermost periphery, the piston plate 24 drives the piston plate 1 22 to slide along the inner wall of the hydraulic box 21 through the fixed cylinder 23, forcing the liquid inside the hydraulic box 21 to enter the hydraulic telescopic rod 1 32 through the flow port 31, forcing the multiple hydraulic telescopic rods 1 32 to extend, so that the other ends of the multiple hydraulic telescopic rods 1 32 are in contact with the outer wall of the steering knuckle. Through the application of the above components, the multiple hydraulic telescopic rods 1 32 can be tightly attached to the outer wall of the steering knuckle, thereby improving the clamping efficiency of the equipment.

[0039] For example 2, please refer to Figure 5 - Fig.10 The present invention is a multi-hole drilling device for a steering knuckle. On the basis of the first embodiment, a fitting component 4 includes a hydraulic box 2 41 fixedly connected to the other end of a hydraulic telescopic rod 1 32. A plurality of piston plates 3 42 are slidably connected to the inner wall of the hydraulic box 2 41. One end of the push bracket 15 away from the electric telescopic rod 14 is fixedly connected to the outer wall of the piston plate 2 24. By utilizing the characteristic that the hydraulic telescopic rod 1 32 moves outward, a fitting component 4 is arranged inside the device. When the liquid inside the hydraulic box 21 enters the hydraulic telescopic rod 1 32 through the flow port 31, the liquid inside the hydraulic telescopic rod 1 32 will enter the inside of the hydraulic box 2 41, forcing the piston plate 3 42 inside the hydraulic box 2 41 to slide outward and fit on the outer wall of the steering knuckle, so that the piston plate 3 42 can be tightly attached to the outer wall of the arc-shaped piston plate 3 42, presenting a shape as shown in the figure.

The sliding fixed rod 45 controls the outward extension length and speed of the hydraulic telescopic rods 2 46 at both ends. The outward extension length of the hydraulic telescopic rods 2 46 at both ends is controlled by the fixed rod 45 to ensure that the upper and lower heights of the two steering knuckles are equal after the clamping is completed, so as to avoid the unequal heights during drilling, which leads to the deviation of the center position of the drilling hole.

[0042] The control component 5 includes a sliding cylinder 51 fixedly connected to the side wall of the piston plate 24, a pushing frame 52 is slidably connected to the inner wall of the sliding cylinder 51, and a spring 2 53 is fixedly connected to the side wall of the pushing frame 52. The control component 5 is arranged inside the equipment by utilizing the characteristic that the pushing bracket 15 drives the piston plate 24 to slide inward along the fixed cylinder 23. When the piston plate 24 drives the pushing frame 52 to move through the sliding cylinder 51, the pushing frame 52 contacts the side wall of the hollow plate 511, and as the piston plate 24 continues to move laterally, the spring 2 53 will deform and accumulate mechanical power.

[0043] The control component 5 also includes a hydraulic groove 54 provided on the side wall of the piston plate 22, a transmission pipe 55 is connected through the side wall of the hydraulic groove 54, a sliding ring 56 is slidably connected to the side wall of the sliding ring plate 33, a plurality of limiting holes 57 are provided on the side wall of the sliding ring 56, a hollow plate 511 is fixedly connected to the side wall of the sliding ring 56, and a piston square plate 512 is slidably connected to the inner wall of the hydraulic groove 54.

At this time, the liquid inside the hydraulic groove 54 passes through The transmission pipe 55 enters the hydraulic telescopic rod three 510, and the extended hydraulic telescopic rod three 510 will force the sliding baffle 59 to move away from the limiting hole 57, so that the sliding baffle 59 loses the restriction on the sliding ring 56. At this time, the spring two 53 will release the mechanical power, forcing the pushing frame 52 to move outward along the inner wall of the sliding cylinder 51. The outward-moving pushing frame 52 will force the sliding ring 56 to slide outward along the outer wall of the sliding ring plate 33 through the hollow plate 511. The outward-moving hollow plate 511 will block the flow port 31, cutting off the flow path between the hydraulic box 21 and several hydraulic telescopic rods 32. Through the application of the above-mentioned components, it is avoided that when drilling, the shaking force generated by drilling is avoided because the hydraulic telescopic rods 32 are in a state of communication with each other, causing the liquid of each hydraulic telescopic rod 32 to circulate, and the hydraulic telescopic rod 32 to slightly expand and contract, causing errors in drilling.

At this time, the electric telescopic rod 14 is extended, and the piston plate 24 is driven to slide along the inner wall of the fixed cylinder 23 by pushing the bracket 15. When the piston plate 24 reaches the outermost periphery, the piston plate 24 drives the piston plate 1 22 to slide along the inner wall of the hydraulic box 1 21 through the fixed cylinder 23, forcing the liquid inside the hydraulic box 1 21 to enter the hydraulic telescopic rod 1 32 through the flow port 31, forcing multiple hydraulic telescopic rods 1 32 to extend, so that the other ends of the multiple hydraulic telescopic rods 1 32 are in contact with the outer wall of the steering knuckle. Through the application of the above components, the multiple hydraulic telescopic rods 1 32 can be tightly attached to the outer wall of the steering knuckle, thereby improving the clamping efficiency of the equipment.

[0050] Taking advantage of the outward movement of the hydraulic telescopic rod 1 32, a fitting component 4 is provided inside the device. When the liquid inside the hydraulic box 1 21 enters the hydraulic telescopic rod 1 32 through the flow port 31, the liquid inside the hydraulic telescopic rod 1 32 will enter the inside of the hydraulic box 2 41, forcing the piston plate 3 42 inside the hydraulic box 2 41 to slide outward and fit on the outer wall of the steering knuckle, so that the piston plate 3 42 can be tightly attached to the outer wall of the arc-shaped piston plate 3 42, presenting a Figure 5 state, through the application of the above-mentioned components, the contact position of the equipment can adapt to the arc-shaped outer wall of the steering knuckle, avoid the gap in the clamping, and avoid the existence of the gap causing slight misalignment of the steering knuckle during subsequent drilling.

[0051] By utilizing the characteristic of the pushing bracket 15 driving the piston plate 24 to slide inwardly along the fixed cylinder 23, a control component 5 is arranged inside the device. When the piston plate 24 drives the pushing bracket 52 to move through the sliding cylinder 51, the pushing bracket 52 contacts the side wall of the hollow plate 511, and as the piston plate 24 continues to move laterally, the spring 2 53 will deform and accumulate mechanical power; and when the piston plate 22 moves laterally to squeeze the liquid inside the hydraulic box 21, after the multiple hydraulic telescopic rods 32 complete the clamping, the continued transverse movement of the piston plate 22 will force a high-pressure environment to form inside the hydraulic box 21, and the high-pressure force will act on the piston square plate 512, forcing the piston square plate 512 to slide along the inner wall of the hydraulic groove 54. At this time, the liquid inside the hydraulic groove 54 enters the hydraulic telescopic rod 3 510 through the transmission pipe 55, and the extended The hydraulic telescopic rod three 510 will force the sliding baffle 59 to move away from the limiting hole 57, so that the sliding baffle 59 loses the restriction on the sliding ring 56. At this time, the spring two 53 will release the mechanical power, forcing the pushing frame 52 to move outward along the inner wall of the sliding cylinder 51. The outward-moving pushing frame 52 will force the sliding ring 56 to slide outward along the outer wall of the sliding ring plate 33 through the hollow plate 511. The outward-moving hollow plate 511 will block the flow port 31, cutting off the flow path between the hydraulic box 21 and the plurality of hydraulic telescopic rods 32. Through the application of the above-mentioned components, the jitter force generated by drilling can be avoided because the hydraulic telescopic rods 32 are in a state of communication during drilling, causing the liquid in each hydraulic telescopic rod 32 to circulate, resulting in a slight expansion and contraction of the hydraulic telescopic rod 32, causing errors in drilling.
