[0041] Preferably, by contacting the first lever 33 and the second lever 34 with the baffle 26, qualified and unqualified screws can be dropped into different storage boxes 32 to achieve a screening effect on the screws after detection.

[0042] Please refer to the attached Figure 1 -Attached Figure 6In a preferred embodiment, the discharge assembly includes: a three-jaw chuck 3, a circular groove penetrating therethrough is provided at the top of the turntable 2, the three-jaw chuck 3 is rotatably installed inside the circular groove, a gear ring 42 and a fourth gear 43 meshing with each other are rotatably installed inside the turntable 2, the gear ring 42 is fixedly sleeved on the surface of the three-jaw chuck 3, a second gear 30 is rotatably installed at the bottom of the turntable 2, the top of the second gear 30 is fixedly installed at the bottom center of the fourth gear 43 through a connecting shaft, and when the second gear 30 and the third gear 31 are in contact, the second gear 30 and the third gear 31 are meshed, a baffle 26 is slidably provided at the bottom of the turntable 2, the baffle 26 is used to block the three-jaw chuck 3, an arc groove 27 is provided at the bottom edge of the turntable 2, a slider is slidably installed inside the arc groove 27, the bottom of the slider is fixedly installed on the top of the baffle 26, and a second spring rod is fixedly installed at the inner end of the arc groove 27 28, the telescopic end of the second spring rod 28 is fixedly installed on the side of the slider, driving the third slope to be opened on both sides of the end of the baffle 26. When the baffle 26 follows the slider to move to the maximum stroke of the arc groove 27, the first lever 33 and the second lever 34 slide between the third slope on the baffle 26. The turning assembly includes: a first bracket 4, the vertical side of the first bracket 4 is fixedly installed on the top of the bottom plate 1, the horizontal side of the first bracket 4 is fixedly installed with two first hydraulic telescopic rods, and a clamping block 5 is arranged below the horizontal side of the first bracket 4, the telescopic end of one of the first hydraulic telescopic rods is fixedly installed on the top of the clamping block 5, and a second hydraulic telescopic rod is also horizontally arranged below the horizontal side of the first bracket 4, the telescopic end of the second hydraulic telescopic rod is fixedly installed with a tool holder, and a turning tool 6 is installed on the tool holder, and the telescopic end of the other first hydraulic telescopic rod is fixedly installed on the surface of the second hydraulic telescopic rod;

[0043] Specifically, the material is placed inside the three-jaw chuck 3 and clamped, and the pressing block 5 cooperates with the three-jaw chuck 3 to clamp the material, and then the turning tool 6 is used to turn the material.

[0044] The working principle of the present invention is as follows: firstly, the material is placed inside the three-jaw chuck 3 and clamped. At this time, due to the setting of the baffle 26, the material will not fall. Then, the first motor is started to drive the column to rotate ninety degrees. The rotation of the column drives the turntable 2 to rotate. The rotation of the turntable 2 drives the three-jaw chuck 3 with the material to rotate to the bottom of the first bracket 4. Then, the first hydraulic telescopic rod and the second hydraulic telescopic rod are started, so that the clamping block 5 cooperates with the three-jaw chuck 3 to clamp the material and then the material is turned by the turning tool 6. During turning, the third gear 31 connected thereto is driven to rotate by the corresponding third motor. The third gear 31 rotates to drive the second gear 30 meshing therewith. The second gear 30 rotates to drive the fourth gear 43 and the gear ring 42 connected thereto to rotate. The gear ring 42 rotates to drive the corresponding three-jaw chuck 3 to rotate. The rotation of the three-jaw chuck 3 drives the turning material to rotate.

[0045] When the material is turned, the turntable 2 is rotated 90 degrees again, and the turned screw will be transferred to the bottom of the second bracket 7, and the second motor 44 is started synchronously to drive the corresponding third gear 31 to rotate, the rotation of the third gear 31 drives the second gear 30 meshing therewith to rotate, the rotation of the second gear 30 drives the fourth gear 43 to rotate, the rotation of the fourth gear 43 drives the gear ring 42 to rotate, the rotation of the gear ring 42 drives the corresponding three-jaw chuck 3 to rotate, the corresponding three-jaw chuck 3 rotates and drives the clamped screw to rotate, when the turned screw is in the inspection position After the detection ring 20 is below, it should be noted that when the machined screw is below the detection ring 20, the pneumatic telescopic rod 19 controls the detection ring 20 to move downward, so that the detection ring 20 and the screw are in contact, and when the detection ring 20 and the screw are in contact, the pneumatic telescopic rod 19 and the air pump are controlled by the solenoid valve to cut off the air, and the pneumatic telescopic rod 19 is connected to the outside world. Further, when the screw rotates inside the detection ring 20, the screw will be connected to the detection ring 20 through a thread, so that the detection ring 20 and the telescopic end of the pneumatic telescopic rod 19 can move downward;

[0046] If the turned thread is qualified, the detection ring 20 and the telescopic end of the pneumatic telescopic rod 19 will drive the straight copper bar 24 to move downward until it contacts the lower horizontal edge of the U-shaped copper bar 23. At this time, the U-shaped copper bar 23 contacts the straight copper bar 24, and the second motor 44 is reversed through the relay, which can further separate the turned screw and the detection ring 20. When the two second copper sheets 25 contact, the second motor 44 is controlled to stop working through the relay. In addition, the solenoid valve controls the pneumatic telescopic rod 19 to be connected to the air pump, and then the pneumatic telescopic rod 19 drives the detection ring 20 to move upward and separate from the screw, and then the turntable is turned again. 2 is rotated 90 degrees, and the screw moves out of the detection ring 20. During the rotation of the turntable 2, the baffle 26 will contact the first lever 33, and the first lever 33 will hinder the movement of the baffle 26, so that the turntable 2 and the baffle 26 can slide relative to each other, and the baffle 26 will no longer block the bottom of the three-jaw chuck 3, and the qualified screws will fall into the corresponding storage box 32. When the slider and the baffle 26 move to the maximum stroke, the first lever 33 and the third slope on the baffle 26 slide relative to each other, so that the elastic force generated by the second spring rod 28 can reset the baffle 26.

[0047] If the turned thread is unqualified, in summary, the detection ring 20 will stop moving upward when it moves down along the screw to the defective part. Since the turned screw will drive the detection ring 20 to rotate, the rotation of the detection ring 20 drives the two pneumatic telescopic rods 19 to rotate, the rotation of the two pneumatic telescopic rods 19 drives the turntable 18 to rotate, the rotation of the turntable 18 drives the second cone plate 16 to rotate, the rotation of the second cone plate 16 drives the first cone plate 15 to rotate, the rotation of the first cone plate 15 drives the belt 9 and the pulley 10 to rotate, the rotation of the pulley 10 drives the connecting rod 11 to rotate, the rotation of the connecting rod 11 drives the first gear 12 to rotate and causes the torsion spring 36 to generate torque, Due to the arrangement of the ramp rod 38, the first gear 12 can only rotate in one direction at this time. The rotation of the first gear 12 drives the two racks 13 to move in the opposite direction. The opposite movement of the two racks 13 drives the first lever 33 to move away from the turntable 2, and the second lever 34 moves towards the turntable 2, so that the second lever 34 is located below the turntable 2. In addition, when the second cone plate 16 drives the two first copper sheets 17 to contact, the two first copper sheets 17 contact and control the second motor 44 to rotate in the opposite direction through the relay, which can further separate the turned screw and the detection ring 20. When the two second copper sheets 25 contact, the second motor 44 is controlled to rotate in the opposite direction through the relay. The relay controls the second motor 44 to stop working, the solenoid valve controls the pneumatic telescopic rod 19 to be connected to the air pump, and then the pneumatic telescopic rod 19 drives the detection ring 20 to move upward and separate from the screw, and then the turntable 2 is rotated ninety degrees again, and the screw moves out of the detection ring 20. During the rotation of the turntable 2 this time, the baffle 26 will contact the second lever 34. In summary, the baffle 26 will slide relative to the turntable 2, and the unqualified screws will fall into the corresponding storage box 32, and then the second lever 34 and the baffle 26 will slide relative to each other, and the baffle 26 will reset to continue to block the three-jaw chuck 3. It should be said that It is clear that when the turntable 2 rotates, it will also drive the unlocking block 8 to rotate. When the unlocking block 8 contacts the slope on the ramp block 14, the ramp block 14 will move upward. The upward movement of the ramp block 14 drives the connecting plate 39 and the ramp rod 38 to move upward, and the ramp rod 38 and the first gear 12 are separated. Then, the torsion force generated by the torsion spring 36 will reverse and reset the first gear ring 42, and further reset the first cone plate 15, the first lever 33 and the second lever 34. Finally, when the unlocking block 8 and the ramp block 14 are separated, the tension generated by the fourth spring rod 41 will cause the ramp rod 38 to continue to be located between the adjacent convex teeth of the first gear 12.

[0048] In summary, the material can be turned continuously by reciprocating in sequence, and the turned screws can be detected simultaneously and then automatically separated and unloaded, thereby improving the use effect of the equipment.

[0049] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
