The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] Please refer to the attached Figure 1 : The overall structure of the automatic deburring equipment for the parts involved is shown, and the automatic deburring equipment includes a fixture positioning turntable unit 10, a pneumatic robot arm feeding unit 20, a pneumatic robot arm discharging unit 30, a pneumatic deburring unit 40, a deburring unit 50, an air blowing cleaning unit 60 and a system action control unit, wherein the fixture positioning turntable unit 10 has a circular turntable 11, and a six-division positioning fixture 12 is provided on the circular turntable 11, and the pneumatic robot arm feeding unit 20, the two-position pneumatic deburring unit 40, the deburring unit 50, the pneumatic robot arm discharging unit 30 and the air blowing cleaning unit 60 are arranged in sequence along the circumference of the circular turntable corresponding to a division position.

[0029] Please refer to the attached Figure 2The automatic burr removal equipment is arranged and set with the fixture positioning turntable unit 10 as the center. The fixture positioning turntable unit 10 includes a circular turntable 11 that can rotate and position according to a preset position. Six positioning fixtures 12 are evenly arranged on the circular turntable 11 according to six divisions. Of course, according to the actual processing requirements and different sizes, it is entirely possible to consider setting it as a five-division or eight-division positioning fixture. According to the understanding of technical personnel in the industry, it is reasonable to increase or decrease it by yourself.

[0030] The fixture positioning turntable unit 10 includes a circular turntable 11, six positioning jigs 12 and four clamping cylinders 13, wherein the six part positioning jigs are evenly distributed around the circumference of the circular turntable 11, and four consecutive positioning jigs 12 are provided opposite to each other with clamping cylinders 13 that press against the positioning jigs 12, two of the part positioning jigs 12 without clamping cylinders 13 are respectively used as the first and sixth workstations, and four consecutive part positioning jigs with clamping cylinders 13 are respectively used as the second, third, fourth and fifth workstations.

[0031] In fact, the first to sixth workstations are artificially distinguished only to facilitate the description and identification of the corresponding processing parts at different workstations and the corresponding completed processing flow actions.

[0032] According to the diagram and process design, we can assume that the first station is used for loading, putting the main body parts that need to be deburred and de-burred on the positioning fixture. The first station is to clamp and position the corresponding clamping cylinder after loading, and start preparing for subsequent process processing. The second and third stations are both pneumatic deburring units 40, which are designed according to actual process requirements. The main body part can have multiple holes that need to be deburred at the same time, or it can be necessary to perform secondary deburring, so two positions are arranged for deburring. The fourth position is the deburring unit 50. For this implementation case, it can be seen that there are holes that need to be deburred on both corners of the main body part, so the pneumatic deburring unit 40 on the second station removes the burrs on the first hole, and the pneumatic deburring unit 40 on the third station removes the burrs on the second hole. At the fourth station, the two holes are deburred simultaneously. At the fifth station is the pneumatic robot arm discharge unit 30, which is responsible for grabbing and unloading the body parts that have been deburred and removed. The sixth station is used to clean the remaining burrs on the cleaning station to avoid affecting the parts to be processed in the next process cycle.

[0033] The pneumatic robot arm feeding unit 20 is arranged outside the first workstation, corresponding to the part positioning fixture 12 that is loaded onto the first workstation, and includes a movable guide rail 21, a movable guide rail screw module 22 and a grabbing pneumatic device 23, wherein the end of the movable guide rail 21 is provided with a movable guide rail screw module 22 for driving the movable guide rail 21 to transport parts, and a grabbing pneumatic device 23 for grabbing parts and loading materials is provided at one end of the movable guide rail 21 close to the part positioning fixture.

[0035] The limit sensor 47 is used to sense the position of the servo positioning device 48. Once the upper limit sensor is exceeded or the lower limit sensor is exceeded, a stop signal will be given and the servo positioning device 48 will stop moving. The servo positioning device 48 is actually a moving mechanism that drives the drilling shaft 44 to move up and down. The drilling shaft 44 drives the drill bit 46 to extend into the hole of the body part to perform the burr removal operation.

[0036] Please refer to the attached Figure 4 The deburring unit 50 includes a deburring bracket 51, a mechanical slide 52, a servo motor 53, a servo positioning device 58, a drilling shaft 54, a drill bit bracket 55, a brush 56 and a limit sensor 57, wherein the deburring bracket 51 is fixed to the outer side of the circumference of the circular turntable 11 on the work table, the mechanical slide 52 is installed on the deburring bracket 51, and the servo motor 53 driving the mechanical slide 52 is installed on the top of the mechanical slide, the drill bit bracket 55 is installed on the servo positioning device 58 for guiding the sliding of the mechanical slide 52, the drilling shaft 54 ​​is arranged in the drill bit bracket 55, and the brush 56 is linked below the drilling shaft 54; limit sensors 57 are respectively installed on the upper and lower parts of the side of the mechanical slide 52.

[0037] The pneumatic manipulator discharge unit 30 is arranged outside the fifth station, corresponding to the grabbing and unloading of materials from the fifth station, wherein the transmission and action structures are completely consistent with the pneumatic manipulator feeding structure, except for the action position and direction. It includes a moving guide rail, a moving guide rail screw module and a grabbing pneumatic device, wherein the end of the moving guide rail is provided with a moving guide rail screw module for driving the moving guide rail to transport parts, and a grabbing pneumatic device for grabbing parts and loading materials is provided at one end of the moving guide rail close to the part positioning fixture.

The pressing cylinder 13 on the turntable presses the product forward, and the circular turntable 11 starts to rotate one workpiece position. The grabbing pneumatic device 23 grabs the second product and goes down to the next empty position again. The drilling shaft 44 on the first pneumatic deburring unit starts deburring and returns after completion. After the pneumatic deburring unit 40 returns, the circular turntable 11 rotates one station again, and the part moves to the next station. The second drilling shaft starts deburring, and the first two working axes continue to work. After the three axes return, the circular turntable 11 rotates one station again, and the deburring unit 50 starts deburring. After the work is completed, each axis returns safely. The circular turntable 11 rotates one station again, the clamping cylinder 13 is released, and the manipulator of the pneumatic manipulator arm discharge unit 30 comes over to grab the processed product and moves it to the discharge conveyor belt. The product flows out of the conveyor belt to a safe designated position. After each axis completes the action, the circular turntable 11 rotates one station again, and the air blowing cleaning unit 60 starts to blow away the debris and impurities at the station.
