[0011] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0012] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this invention.

[0013] Please see Figure 1 As shown, this utility model provides an automatic deburring equipment for steering knuckles, including a guardrail 1, a transfer platform 2, a reversing clamp 3, a support frame 4, a vision system 5, a robot 6, a gripping clamp 7, a tool holder 8, a frame 9, a servo motor 10, a shaft 11, and a rotary table 12.

[0014] like Figure 2 As shown, the servo motor 10 is fixed on the frame 9, and the output end of the servo motor 10 is connected to the shaft 11. The shaft 11 is connected to the rotary table 12, which has two workstations, namely workstation one and workstation two. The fixtures of the two workstations are identical and symmetrically distributed. Each workstation has eight clamping fixtures, divided into four front clamps and four reverse clamps, which clamp four steering knuckles 15 on the front and four steering knuckles 15 on the reverse. When one workstation is located inside the protective railing 1 for deburring, the other workstation is located in the loading and unloading area for manual loading and unloading.

[0015] The protective fence 1 is set up to enclose the deburring area as a safe area. The main components in the deburring area are: robot, vision system and tool holder system. The output end of the robot 6 is equipped with a gripping fixture 7. The gripping fixture 7 is a double-sided fixture, which can grip the front of the steering knuckle 15 on one side and the back of the steering knuckle 15 on the other side.

[0016] The transfer platform 2 is fixed, and the reversing fixture 3 is installed on the transfer platform 2. The reversing fixture 3 is used to switch between forward and reverse gripping of the steering knuckle 15. The support frame 4 is fixed on the transfer platform 2, and the vision system 5 is installed on the support frame 4, located above the reversing fixture 3. The vision system 5 includes an industrial camera and a computing module. When the robot 6 uses the gripping fixture 7 to grasp the steering knuckle 15, it takes a picture and identifies the steering knuckle 15 to correct the rotation direction deviation. The purpose is to accurately find the deburring trajectory line to make the burr removal more uniform. The tool holder 8 is equipped with three tool positions: T1 rotary file, T2 flat file, and T3 sandpaper stick. The three tools are used in combination to complete the removal of burrs of various shapes.

[0017] The working process of an automatic deburring device for steering knuckles is as follows: Figure 4 , 4As shown in Figures 5 and 6, firstly, operator 13 removes four steering knuckles 15 from the five-axis machine tool 14 and places them on four front fixtures at one workstation on the rotary table 12. Then, servo motor 10 starts, driving the rotary table to rotate 180°. At this point, the four steering knuckles switch to the deburring area of ​​the equipment. Next, robot 6 starts, grabs one steering knuckle 15, and moves it under vision system 5 for visual inspection. The calculation module calculates the rotation direction grabbing deviation and corrects the deburring trajectory. Then, robot 6 grabs the steering knuckle 15 and moves it into tool holder 8. Using the workpiece rotation gripped by robot 6, in conjunction with the T1 rotary file, T2 flat file, and T3 sandpaper stick, the steering knuckle is... After removing burrs from all five sides of the steering knuckle 15, robot 6 grips the steering knuckle 15 and enters the transfer table 2. Robot 6 places the steering knuckle 15 on the reversing fixture 3 and then grips it again from the reverse side. The reversing fixture 3 is used to reverse the gripping direction of the steering knuckle 15. Next, robot 6 grips the steering knuckle 15 and performs visual inspection again to correct the rotation direction deviation after the reverse gripping. Then, robot 6 grips the steering knuckle 15 and enters the tool holder 8 again. By using the robot to grip and rotate the workpiece, in conjunction with the T1 rotary file, T2 flat file, and T3, the burrs on the last side of the steering knuckle 15 can be removed. At this point, the burrs on all six sides of the steering knuckle 15 have been removed. Then, robot 6 releases the steering knuckle 15 onto the reverse fixture at station one. After deburring one steering knuckle 15, the remaining three steering knuckles 15 are deburred one by one according to the above steps. After all four steering knuckles 15 are deburred, the servo motor 10 is started to drive the rotary table 12 to rotate 180°. The deburred steering knuckles 15 are then switched to the loading and unloading area, where the operator unloads them.

[0018] This invention can automatically remove burrs during machining, ensuring precise and uniform burr removal, thereby improving work efficiency and reducing labor costs. This device is highly efficient, practical, easy to manufacture, and highly automated.
