[0012] Beneficial effects of the utility model:

[0013] (1) In the utility model, a frosting ring is provided on the left side of the drill bit surface, so that the inner hole can be polished while drilling a hole for the steering knuckle kingpin, thereby reducing steps and increasing production efficiency. The steering knuckle is placed on the workpiece storage table, and the clamping mechanism will clamp the steering knuckle on the storage table through the clamping arm to prevent the steering knuckle from shifting. The operation of the sliding cylinder of the slide mechanism will push the upper end of the punching device to approach the steering knuckle. When it approaches a fixed position, the motor starts to drive the drill bit to drill a hole toward the steering knuckle kingpin position. After the front end of the drill bit enters the steering knuckle, the sliding cylinder will run again while rotating to push it toward the center of the steering knuckle. At this time, the frosting ring at the rear end of the drill bit will polish the inside of the steering knuckle kingpin with the hole drilled. At the same time, because the slide mechanism and the punching mechanism are symmetrically placed and work synchronously, the concentricity of the hole can be enhanced when processing the holes on both sides of the steering knuckle kingpin.

[0014] (2) In the utility model, an electrostatic adsorption steel belt and a workpiece storage table are arranged near the center of one side to adsorb the debris generated during punching. The electrostatic adsorption copper coil will generate an electromagnetic field, so that an electrostatic field is generated under the workpiece storage table. The electrostatic field can generate electric charges on the surface of the electrostatic adsorption steel belt, adsorb the debris to the surface of the steel belt, collect it in large quantities, and then slide the debris into an external recovery basket at the lower end of the chip outlet at a forward tilt angle for recycling.

[0015] (3) In the utility model, by setting the slopes on the left and right sides of the upper end of the workbench, a large amount of debris will fall onto the electrostatic adsorption steel belt while drilling, and some debris will also jump onto the workbench. At this time, the slope of the slope will slide the debris that has collapsed onto the workbench onto the electrostatic adsorption steel belt through the slope, making the workbench cleaner. At the same time, the debris can be processed in a centralized manner to reduce labor.

[0016] In summary, the device has the advantages of enhancing the concentricity of the hole, reducing labor, and increasing production efficiency, and is particularly suitable for the technical field of steering knuckle processing devices. BRIEF DESCRIPTION OF THE DRAWINGS

A transmission rod 413 is provided at the center inside the clamping cylinder 412, and a clamping arm 414 is provided at the upper end of the transmission rod 413 to clamp the upper end of the steering knuckle. A bracket 415 is provided at the center of the lower end of the clamping arm 414 to provide supporting force. The lower end of the bracket 415 is placed on the upper end of the support frame 411, and the front and rear ends of the clamping mechanism 41 are placed symmetrically to increase the clamping pressure and prevent the steering knuckle from shifting during processing.

[0027] Furthermore, a slider base plate 61 is provided at the lower end of the slide mechanism 6, a guide rail 611 is provided at the front and rear sides of the upper end of the slider base plate 61, a slider 612 is provided at the upper end of the guide rail 611, a sliding cylinder 62 is provided at the right side of the slide mechanism 6, a pneumatic rod 621 is provided at the right center of the sliding cylinder 62, a connecting block 622 is provided at the leftmost side of the pneumatic rod 621, the left and right ends of the slide mechanism 6 are symmetrically placed and work synchronously, and the concentricity of the holes on both sides of the steering knuckle kingpin can be enhanced when processing the holes.

[0028] Furthermore, a connecting plate 51 is provided at the lower end of the punching mechanism 5, a motor 53 is provided at the upper end of the connecting plate 51, an output shaft is provided at the center of the right side of the motor 53, a drill bit 52 is provided on the right side of the output shaft, and a frosting ring is provided on the left side of the surface of the drill bit 52, so that the inner hole can be polished while punching the steering knuckle kingpin, thereby reducing steps and increasing production efficiency. Slide blocks 612 are fixedly connected to the front and rear sides of the lower end of the connecting plate 51, and a connecting block 622 is fixedly connected to the center of the lower end of the connecting plate 51. The punching mechanism 5 is symmetrically placed on the left and right sides and works synchronously, so that the concentricity of the holes on both sides of the steering knuckle kingpin can be enhanced when processing the holes.

[0029] Furthermore, an electric copper coil 42 is disposed at the center of one side of the workpiece placement table 4 . The electric copper coil 42 can generate an electromagnetic field, so that an electrostatic field is generated under the workpiece placement table 4 .

[0030] Furthermore, an electrostatic adsorption steel belt 11 is provided in the center of the workbench 1, and slopes are provided on the left and right sides of the upper end of the workbench 1. The slopes are inclined toward the direction of the electrostatic adsorption steel belt 11, and some debris will jump onto the workbench 1. At this time, the slope of the slope will slide the debris that has collapsed onto the workbench 1 onto the electrostatic adsorption belt 11 through the slope. The electrostatic adsorption steel belt 11 extends from the rear side to the front end of the chip outlet 21 and tilts forward. The electrostatic field generated by the electric copper coil 42 can generate electric charges on the surface of the electrostatic adsorption steel belt 11, so that the debris is adsorbed to the surface of the steel belt and collected in large quantities. Then, the debris is tilted forward to slide into the external recovery basket at the lower end of the chip outlet 21 for recycling.

[0031] Working process: First, place the steering knuckle on the workpiece storage table 4, and the clamping cylinder 412 of the clamping mechanism 41 will start to work, retract the transmission rod 413 in the inner center, and extend the transmission rod 413 downward. The transmission rod 413 drives the clamping arm 414 at the upper end to press downward. When pressing downward, the upper end of the steering knuckle will be clamped and imprisoned on the workpiece storage table 4. Then, the sliding cylinder 62 of the slide mechanism 6 will start to move the pneumatic rod 621 in the inner center toward the workpiece storage table 4, and at the same time drive the punching mechanism 5 to move The workpiece storage table 4 is moved close to the workpiece storage table and moved to a processable position. The motor 53 of the punching mechanism 5 is started to drive the drill bit 52 to punch a hole at the steering knuckle kingpin position. After the front end of the drill bit 52 enters the steering knuckle, the sliding cylinder 62 will run and push it toward the center of the steering knuckle while rotating. At this time, the frosting ring at the rear end of the drill bit 52 will polish the inside of the steering knuckle kingpin with the hole punched. At the same time, because the sliding table mechanism 6 and the punching mechanism 5 are symmetrically placed and work synchronously, the concentricity of the hole can be enhanced when processing the holes on both sides of the steering knuckle kingpin.

[0032] Secondly, the electric copper coil 42 at the center of one side of the workpiece storage table 4 close to each other will generate an electromagnetic field, so that an electrostatic field is generated under the workpiece storage table 4. The electrostatic field can generate electric charges on the surface of the electrostatic adsorption steel belt 11, and adsorb the processed chips to the surface of the steel belt, collect them in large quantities, and then slide the chips to the external recovery basket at the lower end of the chip outlet 21 at a forward tilt angle for recycling. A large amount of chips will fall onto the electrostatic adsorption steel belt 11, and some chips will jump onto the workbench 1. At this time, the slope of the slope will slide the chips that have collapsed onto the workbench 1 onto the electrostatic adsorption steel belt 11 through the slope.
