[0043] As Figure 1 shown, the device of the present invention mainly consists of 5 parts, namely a clamping and rotating mechanism 7, an oiling and detecting mechanism 8, a quantitative oiling mechanism 9, a screw feeding mechanism 11 and a positioning fixture mechanism 10.

[0044] As Figure 2 shown, for the positioning fixture mechanism 10, the correct state of the product screw 13 in the fixture is that the screw head contacts the inner cavity bottom surface of the orientation fixture base 15, and then the circumferential positioning is carried out by the notch orientation fixture 14 to give the product a proper position.

[0045] Figure 3 shown, for the quantitative oiling mechanism 9, the positioning fixture mechanism 10 is fixed on the oiling bottom plate 17. Two quantitative valves 19 are connected to two oiling slide cylinders 18 through an adapter plate 20, and then are fixed on the oiling bottom plate 17 around the positioning fixture mechanism 10 in a bidirectional distribution form. In this way, the quantitative valve 19 can move left and right through the oiling slide cylinder 18.

[0046] As Figure 4 shown, for the clamping and rotating mechanism 7, the jaw cylinder 30 is connected to the main rotating floating shaft 35 by a mounting block 29, and the main rotating floating shaft 35 has a hollow structure. Air can enter from the top of the shaft and a floating air pipe joint can be used. The air near the jaw cylinder 30 is supplied to the cylinder, enabling the jaw cylinder 30 to rotate freely at any angle without winding the air pipe. Then, the whole set of mechanism is installed into the inner hole of the rotating shaft outer shaft 23, cooperating with the floating shaft spring 33 and the retaining ring 34 to create an up and down floating amount. Then, on the rotating shaft outer shaft 23, a mechanism similar to a torque limiter is realized by using an internal bearing pulley 28, a slipping friction plate 32, a pre-pressure transmission bushing 31, a pre-pressure spring 26 and a spring pressure regulating nut 25. Under normal circumstances, the pressure of the pre-pressure spring 26 gives a certain frictional force between the slipping friction plate 32 and the internal bearing pulley 28 to drive the rotation of the main rotating floating shaft 35. However, when the resistance encountered by the main rotating floating shaft 35 is greater than the driving frictional force, slipping occurs between the slipping friction plate 32 and the internal bearing pulley 28, enabling the internal bearing pulley 28 to rotate idly while the main rotating floating shaft 35 remains stationary, playing a role in limiting the torque. By adjusting the spring pressure regulating nut 25 to change the spring force of the pre-pressure spring 26, the slipping torque can be changed. Then, the whole set of mechanism is installed on the clamping bottom plate 22 through a mounting flange 27 and connected to the lifting module to realize the up and down movement of the whole set of mechanism.

[0047] As Figure 5As shown, the screw dividing mechanism 11 is fed by the feed track 12, and a material blocking cylinder 40 is installed on the dividing bottom plate 37 through a sheet metal bracket 39 and an L-shaped connecting block 38, and cooperates with the feed track 12 to separate the materials to be used. The material bin 43 is installed on the translational receiving cylinder 42, and then installed as a whole on the rotating cylinder 41, realizing a mechanism that can translate the materials and rotate to the material position to be taken.

[0048] Figure 6 As shown, the oiling detection mechanism 8 mainly relies on the IV2 visual sensor 47 for detection. The IV2 visual sensor 47 is installed on the sensor slide cylinder 45 through the sensor connecting plate 46, realizing an upper position detection and lower position avoidance mechanism.

[0049] The working principle or working process of the present invention is briefly described as follows:

[0050] The feeding track 12 enters the material bin 43 of the translation receiving cylinder 42 of the screw dividing mechanism 11, the rotating cylinder 41 rotates 90 degrees, the lifting servo of the clamping rotating mechanism 7 descends to take the material, the oiling slide cylinder 18 extends the needle to contact the product screw 13, the right clamping jaw clamps the screw from the material bin 43 / the left clamping jaw clamps the product screw 13 from the positioning fixture mechanism 10, and then the lifting servo rises at a uniform speed to oil, the sensor slide cylinder 45 of the oiling detection mechanism 8 rises, and the IV2 visual sensor 47 detects the presence of grease and faults in the linear direction of the threaded surfaces on both sides of the product screw 13, the feeding translation servo shifts, the lifting servo descends, and the left clamping rotating mechanism moves the product screw 13 is screwed into the next product, and the inner / right clamping rotating mechanism positions the product screw 13 in the slot. The left / right clamping rotating mechanism 7 rotates the pulley by rotating the driving motor 24 to make the pulley run. The preload spring 26 presses the built-in bearing pulley 28, and the preload transmission sleeve 31 rotates the main rotating floating shaft 35. After orientation, the floating shaft spring 33 exerts force to push the entire clamping rotating mechanism 7 to push the product screw 13 into the positioning fixture mechanism 10 to clamp the slot orientation fixture 14. Then the screw resistance becomes larger, and the built-in bearing pulley 28 slips and rotates around the rotating shaft outer shaft 23, the main rotating floating shaft 35 does not rotate, and the clamping claws of the left / right clamping rotating mechanism are released, and the lifting servo rises to complete the whole set of actions.
