DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions of the present invention will be further specifically described below through embodiments in combination with the accompanying drawings.

[0029] Combined with Figure 1-7As shown in the figure, a workpiece processing and inspection integrated machine includes a first processing mechanism 1, a second processing mechanism 2, an inspection mechanism 3 and a feeding mechanism. The feeding mechanism includes a first feeding mechanism 4 and a second feeding mechanism 5. The first feeding mechanism 4 is connected to the first processing mechanism 1 and the second processing mechanism 2, and the second feeding mechanism 5 is connected to the first processing mechanism 1 and the inspection mechanism 3;

[0030] The first feeding mechanism 4 includes a conveyor belt 6, a first cylinder 7 provided on a frame above the conveyor belt 6, and a material taking cylinder 8 connected to the end of the first cylinder 7. A second cylinder 9 is further provided at the front end of the frame. A double-headed cylinder 10 is also connected to the frame below the second cylinder 9 in a lifting manner. A blanking arm 11 is provided on each side of the double-headed cylinder 10. The second cylinder 9 drives the double-headed cylinder 10 to lift and lower. After the material taking shaft at the front end of the material taking cylinder 8 inserts and obtains the workpiece and then retracts, when it reaches above the conveyor belt 6, the double-headed cylinder 10 descends and the two blanking arms 11 contract, blocking and dropping the workpiece on the material taking cylinder 8 onto the conveyor belt 6;

[0031] The second feeding mechanism 5 includes a bracket 12, a first material taking arm 13, a first feeding arm 14, a second material taking arm 15 and a second feeding arm 16 provided on the bracket 12;

[0032] The first material taking arm 13 is swingably connected to the rear end of the conveyor belt 6. A first clamping mechanism 17 corresponding to the workpiece is provided at the end of the first material taking arm 13. A column 18 is connected to the bracket 12 in a left-right moving manner. The first feeding arm 14 is connected to the lower end of the column 18 in a lifting manner. A second clamping mechanism 19 corresponding to the workpiece is provided at the end of the first feeding arm 14. After the first material taking arm 13 obtains the workpiece from the conveyor belt 6, it swings backward and places the workpiece on the second clamping mechanism 19 of the first feeding arm 14. After the second clamping mechanism 19 obtains the workpiece, the first feeding arm 14 rises, and the column 18 drives the first feeding arm 14 to displace, sending the workpiece into the second processing mechanism 2;

[0033] Both the second material taking arm 15 and the second feeding arm 16 include a right-angled arm body and a bowl-shaped material taking part 20 provided at the end of the right-angled arm body. An electromagnet is provided inside the bowl-shaped material taking part 20. Since the workpieces contacted by the second material taking arm 15 and the second feeding arm 16 have been finely processed, in order to avoid damaging the workpieces, a method of sleeving and adsorbing is designed to obtain the workpieces. The second material taking arm 15 is swingably connected to the bracket 12, and the second feeding arm 16 is swingably connected to a slider 21. The slider 21 is slidably connected to the slide rail of the bracket 12 in a front-back manner;

[0034] After the second workpiece fetching arm 15 picks up a workpiece from the second processing mechanism 2, the second workpiece fetching arm 15 swings backward to place the workpiece below in the workpiece fetching part 20. The second feeding arm 16 displaces towards the second workpiece fetching arm 15 and swings forward, so that the workpiece fetching part 20 of the second feeding arm 16 is located below the workpiece fetching part 20 of the second workpiece fetching arm 15. Then, the electromagnet of the workpiece fetching part 20 of the second feeding arm 16 is powered off, and the workpiece falls into the workpiece fetching part 20 of the second feeding arm 16. The slider 21 resets to send the workpiece above the detection mechanism 3, and then the second feeding arm 16 resets to convey the workpiece to the detection mechanism 3.

[0035] In another embodiment, in combination with Figure 5 and Figure 6 as shown, three servo motors for driving the first workpiece fetching arm 13, the second workpiece fetching arm 15 and the second feeding arm 16 to swing are further provided on the bracket 12.

[0036] In another embodiment, as shown in Figure 6 the first clamping mechanism 17 includes a clamp driven by a third air cylinder, and the second clamping mechanism 19 includes a clamp driven by a fourth air cylinder.

[0037] In another embodiment, in combination with Figure 5 and Figure 6 as shown, the column 18 is a hollow column 18. The column 18 is movably connected to the bracket 12 in the left-right direction through a frame 22, and a fifth air cylinder 23 for driving the frame 22 to displace is further provided on the bracket 12.

[0038] In another embodiment, in combination with Figure 5 and Figure 6 as shown, a lead screw mechanism 24 for driving the first feeding arm 14 to move up and down is further provided at the top of the frame 22.

[0039] In another embodiment, in combination with Figure 5 and Figure 6 as shown, a sixth air cylinder 25 for driving the slider 21 to displace is further provided on the bracket 12.

[0040] In another embodiment, as shown in Figure 1 the first processing mechanism 1 includes a first machine housing, a first fixture provided at the front end inside the first machine housing, and a first tool holder movably connected to the rear end of the first fixture. A plurality of first tools for tapping, drilling, chamfering and cutting are provided on the first tool holder.

[0041] In another embodiment, a feeding mechanism is further provided at one end of the first processing mechanism 1 away from the fixture. The feeding mechanism includes a feeding rail and a propulsion mechanism. A steel bar is arranged on the feeding rail. The steel bar is placed on the feeding rail, and the propulsion mechanism pushes the steel bar to move towards the fixture of the first processing mechanism 1, so that the end of the steel bar penetrates out of the fixture to an appropriate distance. Then the fixture clamps, and the tool holder moves, so that each tool sequentially performs tapping, drilling a center hole, chamfering, and cutting on the steel bar.

[0042] In another embodiment, in combination Figure 1 、 Figure 2 and Figure 5 As shown, the second processing mechanism 2 includes a second machine shell, a second fixture 27 arranged at the front end inside the second machine shell, and a second tool holder 28 movably connected to the rear end of the second fixture 27. A plurality of second tools for grinding and chamfering are arranged on the second tool holder 28.

[0043] In another embodiment, the detection mechanism 3 includes a third shell, a platform 29 arranged on the third shell, and a plurality of detection devices 30 connected to the platform 29 in a lifting manner. A conveying rail 31 corresponding to the workpiece is arranged on the platform 29, and a waste output rail 32 communicating with the conveying rail 31 is further arranged on the platform 29. The workpiece passes sequentially under each detection device 30 through the conveying rail 31, and the probes of each detection device 30 are sequentially inserted into the center hole of the same workpiece. Whether the workpiece is qualified is judged by multi-point detection at different heights inside the center hole, and the unqualified workpieces are output through the waste output rail 32.

[0044] Preferably, there are three detection devices 30.

[0045] The working principle of the above structure is as follows: The steel bar is placed on the feeding rail, and the propulsion mechanism pushes the steel bar to move towards the fixture of the first processing mechanism 1, so that the end of the steel bar penetrates out of the fixture to an appropriate distance. Then the fixture clamps, and the tool holder moves, so that each tool sequentially performs tapping, drilling a center hole, chamfering, and cutting on the steel bar;

[0046] When the workpiece is formed and cut, the material taking cylinder 8 displaces to the rear of the workpiece, the material taking shaft at the front end of the material taking cylinder 8 extends and inserts into the workpiece. After the workpiece is cut, the material taking cylinder 8 obtains the workpiece and retracts. After reaching above the conveyor belt 6, the double-headed cylinder 10 descends and the two blanking arms 11 contract, blocking the workpiece on the material taking cylinder 8 onto the conveyor belt 6, and the conveyor belt 6 conveys the workpiece to the second processing mechanism 2;

[0047] When the workpiece is conveyed to the rear end of the conveyor belt 6 and is limited by the limit plate, the first material taking arm 13 swings towards the conveyor belt 6, clamps the workpiece, then swings backward and places the workpiece on the second clamping mechanism 19 of the first feeding arm 14. After the second clamping mechanism 19 obtains the workpiece, the first feeding arm 14 rises, and the column 18 drives the first feeding arm 14 to displace, sending the workpiece to the second fixture 27 in the second processing mechanism 2. The second fixture 27 clamps the workpiece, and the second tool holder 28 displaces to grind and chamfer the cut end face of the workpiece, making both ends of the workpiece smooth and chamfered.

[0048] After the second processing mechanism 2 finishes processing the workpiece, the second material taking arm 15 turns downwards to cover the workpiece in the material taking part 20. The second fixture 27 releases the clamping of the workpiece. The second material taking arm 15 adsorbs and obtains the workpiece and resets, placing the workpiece below in the material taking part 20. The second feeding arm 16 displaces towards the second material taking arm 15 and swings forward, making the material taking part 20 of the second feeding arm 16 located below the material taking part 20 of the second material taking arm 15. Then the electromagnet of the material taking part 20 of the second feeding arm 16 is powered off, and the workpiece falls into the material taking part 20 of the second feeding arm 16. The slider 21 resets to send the workpiece above the detection mechanism 3. Then the second feeding arm 16 resets to convey the workpiece onto the conveying rail 31 on the detection mechanism 3. The workpiece passes successively below each detection device 30 along the conveying rail 31. The probes of each detection device 30 are inserted successively into the central hole of the same workpiece, and multi-point detection at different heights in the central hole is used to determine whether the workpiece is qualified. The unqualified workpieces are output by the waste output rail 32.
