Description

Technical Field

[0001] This utility model relates to the field of steering knuckle flange processing technology, and more specifically, to a steering knuckle flange drilling device. Background Technology

[0002] The steering knuckle flange is part of the steering knuckle (also known as the steering knuckle). It is a disc-shaped structure with evenly distributed bolt holes. These holes are used to mount the brake disc (or brake drum), thereby transmitting the braking force of the braking system to the wheels to achieve the braking effect. Through these holes, the brake disc is tightly connected to the steering knuckle, ensuring that the friction pads can smoothly contact the brake disc during braking to generate the required braking force.

[0003] During the machining of steering knuckle flanges, holes need to be drilled to facilitate subsequent assembly. However, if the drilling is not done properly, the hole walls may become rough and have burrs, which will affect the assembly quality and stability of the steering knuckle flanges in the later stages.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 As shown in Figure 2, a steering knuckle flange drilling device includes a support box 1, a frame 4 fixedly installed on the top of the support box 1, a cylinder 5 fixedly installed on the top of the frame 4, a movable frame 6 fixedly installed at the output end of the cylinder 5, a drilling motor 7 arranged inside the movable frame 6, a deburring mechanism 2 arranged at the output end of the drilling motor 7, a drill rod 8 arranged at the bottom of the deburring mechanism 2, and limit mechanisms 3 arranged on both sides of the top of the support box 1.

[0022] The effects achieved by the above components are as follows: by setting a deburring mechanism 2 to grind and clean the hole wall after drilling the flange, the burrs on the hole wall are removed, the flatness of the hole wall is increased, and the assembly quality of the flange is improved. By setting a limiting mechanism 3 to clamp and limit the flange, the stability of the flange during drilling is improved. Under the action of the cylinder 5, the movable frame 6 is driven to move up and down. When the movable frame 6 moves down, the movable frame 6 drives the drilling motor 7 to move down. The drilling motor 7 drives the drill rod 8 to rotate, so that the drill rod 8 drills the flange placed on the top of the support box 1. After drilling is completed, the cylinder 5 drives the movable frame 6 to move up, so that the drill rod 8 is disengaged from the flange.

[0023] like Figure 3As shown in Figure 4, the deburring mechanism 2 includes a fixed rod 201, which is fixedly installed at the output end of the drilling motor 7. A connecting rod 202 is fixedly installed at the bottom of the fixed rod 201. A grinding cylinder 203 is provided on the surface of the connecting rod 202. The diameter of the grinding cylinder 203 is the same as the diameter of the drill rod 8. The surface of the fixed rod 201 is provided with uniformly distributed grooves 204.

A cleaning brush bristle 207 is provided on the other side of the connecting plate 206.

[0024] The effects achieved by the above components are as follows: By setting the grinding cylinder 203 to grind the flange hole wall, the roughness and burrs on the hole wall are avoided, which would affect the assembly stability of the flange. Under the action of the drilling motor 7, the fixed rod 201 is driven to rotate, and then the fixed rod 201 drives the connecting rod 202 and the drill rod 8 to rotate. The drill rod 8 drills the flange. After drilling is completed, the cylinder 5 drives the movable frame 6 to move down, so that the grinding cylinder 203 moves into the flange hole. The grinding cylinder 203 grinds the hole wall, removes the burrs on the hole wall, and improves the flatness of the hole wall. After grinding is completed, the cylinder 5 drives the movable frame 6 to continue to move down, so that the fixed rod 201 moves into the hole. Under the action of the cleaning bristles 207, the powder on the hole wall is cleaned. Under the elastic force of the spring 205, the connecting plate 206 is squeezed, so that the connecting plate 206 pushes the cleaning bristles 207 to fully contact the hole wall, thereby improving the cleaning effect of the cleaning bristles 207 on the hole wall.

[0025] like Figure 5 As shown, the limiting mechanism 3 includes an arc-shaped clamping plate 301, which is located on the top of the support box 1. A protrusion 302 is fixedly installed on the side of the arc-shaped clamping plate 301 near the frame 4. A threaded cylinder 303 is fixedly installed on one side of the protrusion 302. A limiting motor 304 is fixedly installed on one side of the frame 4. A lead screw 305 is fixedly installed at the output end of the limiting motor 304. One side of the lead screw 305 extends into the interior of the threaded cylinder 303 and is threadedly connected to the threaded cylinder 303.

[0026] The effect achieved by the above components is as follows: by setting a limit motor 304 to drive the lead screw 305 to rotate, the lead screw 305 drives the threaded cylinder 303 to move, the threaded cylinder 303 pushes the arc-shaped clamping plate 301 to move, so that the arc-shaped clamping plate 301 clamps and fixes the flange placed on the top of the support box 1.

[0027] like Figure 5 As shown, two positioning rods 306 are fixedly installed on the side of the arc-shaped clamping plate 301 near the frame 4. The frame 4 has positioning holes inside, and one side of the positioning rod 306 passes through the positioning hole.

[0028] The effect achieved by the above components is as follows: by setting the positioning rod 306 and the positioning hole to cooperate with each other to limit the arc-shaped clamping plate 301, the movement stability of the arc-shaped clamping plate 301 is improved, the arc-shaped clamping plate 301 is prevented from deviating, and the clamping and limiting effect of the arc-shaped clamping plate 301 on the flange is improved.

[0029] like Figure 2 As shown, side plates 9 are fixedly installed on both sides of the movable frame 6, and guide holes are opened on the top of the side plates 9. Guide rods 10 are fixedly installed on both sides of the top of the inner side of the frame 4, and the guide rods 10 pass through the guide holes.

[0030] The effect achieved by the above components is as follows: by setting the side plate 9 and the guide rod 10 to cooperate in limiting the movable frame 6, the stability of the movable frame 6 when moving up and down is improved, thereby improving the accuracy of the drill rod 8 in drilling the flange.

[0031] like Figure 1 As shown, a chip removal groove is provided on the top of the support box 1, and a waste chip collection box 11 is provided on the top of the inner cavity of the support box 1. The waste chip collection box 11 is located at the bottom of the chip removal groove. L-shaped rods 12 are fixedly installed on both sides of the top of the inner cavity of the support box 1, and the L-shaped rods 12 are snapped into the bottom of the waste chip collection box 11.

[0032] The effect achieved by the above components is as follows: by setting up the L-shaped rod 12 for installing and fixing the waste collection box 11, the waste collection box 11 collects the debris generated by drilling, which facilitates the recycling of the debris.

[0033] The working principle of this steering knuckle flange drilling equipment:

[0034] Under the action of cylinder 5, the movable frame 6 is driven to move up and down. When the movable frame 6 moves down, it drives the drilling motor 7 to move down, and the drilling motor 7 drives the drill rod 8 to rotate, so that the drill rod 8 drills a hole in the flange placed on top of the support box 1. After drilling is completed, cylinder 5 drives the movable frame 6 to move up, so that the drill rod 8 is disengaged from the flange. Under the action of drilling motor 7, the fixed rod 201 is driven to rotate, and then the fixed rod 201 drives the connecting rod 202 and the drill rod 8 to rotate. The drill rod 8 drills a hole in the flange. After drilling is completed, cylinder 5 drives the movable frame 6 to move down, so that the grinding cylinder 203 moves into the flange hole. The grinding cylinder 203 grinds the hole wall to remove impurities. The burrs on the hole wall are removed to improve the flatness of the hole wall. After grinding, the cylinder 5 drives the movable frame 6 to continue to move down, so that the fixed rod 201 moves into the hole. Under the action of the cleaning bristles 207, the powder on the hole wall is cleaned. Under the elastic force of the spring 205, the connecting plate 206 is squeezed, so that the connecting plate 206 pushes the cleaning bristles 207 to fully contact the hole wall, thereby improving the cleaning effect of the cleaning bristles 207 on the hole wall. The limit motor 304 drives the lead screw 305 to rotate, and then the lead screw 305 drives the threaded cylinder 303 to move. The threaded cylinder 303 pushes the arc-shaped clamping plate 301 to move, so that the arc-shaped clamping plate 301 clamps and fixes the flange placed on the top of the support box 1.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
