[0042] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0043] refer to Figures 1 to 16 ,like Figures 1 to 16 The machine shown includes a frame 10, which has an intermittently rotating turntable 11. The turntable 11 has several clamps 12 spaced apart along its circumference. Each clamp 12 has a compass foot slot 121 opening radially toward the turntable 11. At the end of the compass foot slot 121 pointing toward the center of the turntable 11, there are sequentially arranged a chuck slot 122 and a lead core insertion slot 123. Nut slots 124 and screw slots 125 are respectively arranged on both sides of the chuck slot 122. The clamps 12 are driven by the turntable 11 to pass sequentially through the compass foot loading station 1, the chuck loading station 2, the nut loading station 3, the chuck lead core pushing station 4, and the screw screwing station 5.

[0044] In the above structure, the turntable 11 is controlled to rotate intermittently and achieve positioning by the cam divider 13. The number of fixtures 12 is preferably 6, ensuring that each station can correspond to one fixture 12. As the turntable 11 rotates, when the fixture 12 reaches the gauge foot loading station 1, the gauge foot a is placed into the gauge foot slot 121. The next step is that the fixture 12 reaches the chuck loading station 2 to receive the chuck b. The next step is that the fixture 12 reaches the nut loading station 3 to receive the locking nut c. The next step is that the fixture 12 reaches the chuck lead core pushing station 4 to push the gauge foot a into the chuck b and at the same time, the lead core d is installed into the chuck b. The next step is that the fixture 12 reaches the screw screwing station 5 to pass the screw e through the chuck b and screw it into the locking nut c to clamp the lead core d and complete the assembly. When the fixture 12 reaches the current station, the fixture 12 behind it corresponds to the previous station, which can realize the synchronous assembly of different processes at different stations and greatly improve production efficiency.

[0045] In this embodiment, the chuck loading station 2 includes a chuck vibratory feeder 21 and a chuck transfer mechanism 20; the output end of the chuck vibratory feeder 21 is connected to a chuck conveying track 211; the chuck transfer mechanism 20 includes a chuck transfer gripper 22, which moves between the outlet of the chuck conveying track 211 and the chuck slot 122 of the clamp 12 located on the chuck loading station 2.

[0046] In the above structure, the chuck vibratory plate 21 arranges the chuck b and transports it to the chuck conveying track 211; the chuck transfer mechanism 20 picks up the chuck b located at the exit position of the chuck conveying track 211 and places it in the chuck slot 122.

[0047] In this embodiment, the nut loading station 3 includes a nut vibratory plate 31 and a nut unloading mechanism 30. The nut unloading mechanism 30 includes a nut conveying track 32 and a nut release gripper 33. One end of the nut conveying track 32 is connected to the output end of the nut vibratory plate 31, and the other end corresponds to the nut slot 124 of the clamp 12 located on the nut loading station 3.

[0048] In the above structure, the nut vibratory plate 31 arranges the locking nut c and then conveys it to the nut conveying track 32. The nut release gripper 33 is used to control the release of the locking nut c so that the locking nut c falls into the nut slot 124.

[0049] In this embodiment, the nut conveying track 32 includes a vertical section 321 and an inclined section 322 connected to each other; the upper end of the inclined section 322 is connected to the output end of the nut vibrating plate 31, and the lower end of the vertical section 321 is located above the nut slot 124; the nut release claw 33 is located at the lower end of the vertical section 321.

[0050] In the above structure, the locking nut c output by the nut vibrating plate 31 is guided by the inclined section 322 and enters the vertical section 321. The nut release gripper 33 is located at the lower end of the vertical section 321. When it is released, the locking nut c falls into the nut slot 124 by its own weight. The vertical section 321 is also provided with a nut blocking gripper 34 located above the nut release gripper 33. The two alternately open and close to realize the lowering of a single locking nut c.

[0051] In this embodiment, the lead core insertion station 4 includes a radial pushing mechanism 40 and a lead core transfer device 50. The radial pushing mechanism 40 includes a guide foot pushing block 41 that moves toward the center of the turntable 11 and a lead core pusher 42 that moves away from the center of the turntable 11. The clamp 12 located on the lead core insertion station 4 is located between the guide foot pushing block 41 and the lead core pusher 42. The length direction of the guide foot groove 121 is in the same direction as the movement direction of the guide foot pushing block 41 and the lead core pusher 42. The lead core transfer device 50 includes a lead core vibrating plate 51 and a lead core transfer mechanism 52. The output end of the lead core vibrating plate 51 is connected to a lead core conveying track 511. The lead core transfer mechanism 52 includes a lead core transfer gripper 521. When transferring the lead core d, the lead core transfer gripper 521 moves from the outlet of the lead core conveying track 511 to between the lead core pusher 42 and the lead core insertion groove 123.

[0052] In the above structure, the radial pushing mechanism 40 is connected to the input shaft of the cam divider 13 via a connecting rod 131. When the input shaft of the cam divider 13 rotates, it controls the reciprocating motion of the guide foot pushing block 41 and the lead core pusher 42 of the radial pushing mechanism 40. When the guide foot pushing block 41 moves towards the center of the turntable 11, it pushes the guide foot a so that the front end of the guide foot a engages with the chuck b. The lead core vibrating plate 51 sorts the lead core d and then transports it to the lead core conveying track 511. The lead core transfer mechanism 52 controls the lead core transfer gripper 521 to pick up the lead core d located at the exit position of the lead core conveying track 511 and move it between the lead core pusher 42 and the lead core insertion slot 123. Then, the lead core pusher 52 moves away from the center of the turntable 11 and pushes the lead core d in the lead core transfer gripper 521 into the chuck b to realize the installation of the lead core d.

[0053] In this embodiment, the radial pushing mechanism 40 is further provided with a vertically moving gauge foot pressing member 43 and a clamping member 44. The gauge foot pressing member 43 is located above the gauge foot slot 121, and the clamping member 44 is located above the clamping slot 122.

[0054] In the above structure, the radial pushing mechanism 40 is also provided with a lifting cam groove 45. While the connecting rod 131 reciprocates, it works with the roller, slider and slide rail through the lifting cam groove 45 to control the lifting and lowering motion of the gauge foot clamping member 43 and the chuck clamping member 44, so that the gauge foot a and the chuck b can be accurately aligned.

[0055] In this embodiment, the screw-in station 5 includes a screw vibratory feeder 60 and an automatic screw-locking device 61. The output end of the screw vibratory feeder 60 is connected to the automatic screw-locking device 61 via a flexible hose (not shown in the figure). The screw-in station 5 also includes a flipping mechanism 62. The automatic screw-locking device 61 is mounted on the flipping mechanism 62. Before the flipping mechanism 62 flips, the automatic screw-locking device 61 is located above the clamp 12 of the screw-in station 5. After the flipping mechanism 62 flips, the automatic screw-locking device 61 reaches the side of the screw slot 125 of the clamp 12 of the station and aligns the screw outlet 611 of the automatic screw-locking device 61 with the screw slot 125.

[0056] In the above structure, the screws e, which are arranged and output by the screw vibrating plate 60, are supplied to the automatic screw locking device 61 through a hose, and the screw locking operation is achieved by the screw locking bit 612 of the automatic screw locking device 61. Since the locking nut e is located on the side of the chuck b, the screw locking bit 612 of the automatic screw locking device 61 needs to reach the side of the screw slot 125 when the screw e is locked with the locking nut c. This position is exactly on the movement path of the clamp 12 when the turntable 11 rotates. Therefore, a flipping mechanism 62 is required to control the position of the automatic screw locking device 61. When locking the screw, it swings down to the side of the screw slot 125, and after the screw locking is completed, it swings up to reset to avoid interference with the movement path of the clamp 12.

[0057] In this embodiment, a guide foot loading station 6 is also provided between the screw insertion station 5 and the guide foot loading station 1 along the rotation direction of the turntable 11.

[0058] In the above structure, the gauge foot material feeding station 6 can remove the assembled gauge foot finished product by manual material handling.

[0059] In this embodiment, at the gauge foot loading station 1, gauge foot a is placed in the gauge foot slot 121 manually or by a gauge foot vibrating plate (not shown in the figure); at the chuck loading station 2, chuck b is inserted into the chuck slot 122; at the nut loading station 3, locking nut c is inserted into the nut slot 124; at the chuck lead core insertion station 4, lead core d is inserted into the lead core insertion slot 123; at the screw insertion station 5, screw e is screwed through chuck b and engaged with locking nut c.

[0060] In this embodiment, the chuck b is provided with a lead core mounting hole b1 that is opened in the same direction as the gauge foot a, and a clamping slot b2 that is opened through the wall of the lead core mounting hole b1 and is arranged parallel to the axis of the lead core mounting hole b1; the chuck b is also provided with a clamping hole b3 that passes through the chuck b and the clamping slot b2, and the screw e passes through the clamping hole b3 and engages with the locking nut c to shrink the clamping slot b2 so as to clamp the lead core d in the lead core mounting hole b1.

[0061] In this embodiment, the chuck transfer jaw 22 of the chuck transfer mechanism 20, the nut release jaw 33 and the nut blocking jaw 34 of the nut unloading mechanism 30, the guide foot pushing block 41, the lead core push pin 42, the guide foot pressing clamping member 43 and the chuck pressing member 44 of the radial pushing mechanism 40, the lead core transfer jaw 521 of the lead core transfer mechanism 52, and the movement of the flipping mechanism 62 are driven by conventional cylinders and sliders, which are conventional technologies in the field and will not be described in detail here.

[0062] In the above structure, the automatic wire locking device 61 is an existing device and will not be described in detail here.

[0063] The beneficial effects of the present invention are as follows: The turntable 11 is controlled to rotate intermittently and achieve positioning by the cam divider 13. The number of clamps 12 is preferably 6, ensuring that each station can correspond to one clamp 12. As the turntable 11 rotates, when the clamp 12 reaches the gauge foot loading station 1, the gauge foot a is placed into the gauge foot slot 121. The next step is that the clamp 12 reaches the chuck loading station 2 to receive the chuck b. The next step is that the clamp 12 reaches the nut loading station 3 to receive the locking nut c. The next step is that the clamp 12 reaches the chuck lead core pushing station 4 to push the gauge foot a to engage with the chuck b while inserting the lead core d into the chuck b. The next step is that the clamp 12 reaches the screw screwing station 5 to pass the screw e through the chuck b and screw it into the locking nut c to clamp the lead core d and complete the assembly. When the clamp 12 reaches the current station, the clamp 12 behind it corresponds to the previous station, which can realize the synchronous assembly of different processes at different stations and greatly improve production efficiency.

[0064] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications assumed above should also be considered within the scope of protection of the present invention.
