the process of taking, conveying and discharging specifically comprises the following steps: first pneumatic fixture 9 in first material loading manipulator 8 takes out crank connecting rod 20 with horizontal gesture from revolving stage 7 to rely on sideslip guide rail 1 displacement to a positioning jig that is close to revolving stage 7, first pneumatic fixture 9 is just to the material loading interval in this positioning jig this moment, and approach this positioning jig through first propulsion cylinder 10, get simultaneously through first getting and put cylinder 11 and realize descending, with the boss 3 and the three-jaw finger cylinder 6 that realize placing this positioning jig respectively to the both ends of the crank connecting rod 20 that will be centre gripping, and rise and retreat through the material loading interval.
After the crank connecting rod 20 is arranged on the positioning jig, the crank connecting rod 20 can be lifted to be close to and contact with the chamfering tool 16 of the chamfering motor 15 through the lifting of the feeding platform 2, and the chamfering tool 16 rotates through the acting force of the chamfering motor 15 to chamfer the surface of the chamfering tool contacted with the crank connecting rod 20 instantly; in the process, the splash guard sleeve 17 fully wraps the chamfering tool 16, and the lower end of the splash guard sleeve is vertically movable, so that after the pre-chamfering surface of the crank connecting rod 20 is contacted with the lower end of the splash guard sleeve 17, the lower end of the splash guard sleeve can be abutted against the lower end of the splash guard sleeve to move upwards along the upper end of the splash guard sleeve 17, and the part of the pre-contacted part of the chamfering tool 16 and the crank connecting rod 20 is sealed in the abutting process, so that metal scraps in the milling process cannot splash; the suction pump can act vacuum in the feeding space 18 through the suction pipe 19, and the waste scraps can be collected through the suction pipe 19; this will ensure the sanitation of the environment at the machining site and facilitate the collection and disposal of the shavings produced during the milling process.
In addition, a feeding hole is formed in one end of the transfer table 7, a feeding track 24 is arranged at the feeding hole, a cavity 25 communicated with the feeding hole and used for the crank connecting rod 20 to enter in a horizontal posture is arranged in the transfer table 7, a clamping opening 27 for dividing the transfer table 7 into two parts is formed in the middle section of the transfer table 7, limiting plates 26 used for limiting the outer side parts of the middle section of the crank connecting rod 20 are arranged on two sides of the cavity 25, the limiting plates 26 correspond to two sides of the clamping opening 27, the limiting plates 26 can vertically lift up and down to achieve avoidance, and therefore the first pneumatic clamp 9 can enter the cavity 25 through the clamping opening 27 to clamp the middle section of the; so as to realize material taking.
