DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 5 The present invention provides a steering wheel connecting nut loading machine, including a support platform 2 and a dividing plate 15 connected to the top of the support platform 2, the dividing plate 15 is connected to a motor 24 for driving the dividing plate 15 to rotate, that is, the power output end of the motor 24 is connected to the dividing plate 15. The dividing plate 15 is connected to a limit frame 11 for guiding the steering wheel nut, and at least four limit frames 11 are provided, usually six limit frames 11 are provided, and the adjacent angles are 60 degrees. The bottom of the support platform 2 is connected to a support frame 1, and the support frame 1 is connected to a lifting mechanism for lifting the steering wheel nut. The lifting mechanism includes an electric cylinder 4, a push rod 5, and a lifting block 8. The electric cylinder 4 is used to drive the push rod 5 to rise and fall, and the lifting block 8 is fixed to the top of the push rod 5. The push rod 5 is connected to a positioning plate 6 for positioning the dividing plate 15. The push rod 5 runs through the support platform 2, and the push rod 5 is slidably connected to the support platform 2, so that the push rod 5 can be lifted and lowered stably.

[0026] The electric cylinder 4 can drive the push rod 5 to rise, that is, the positioning plate 6 and the top block 8 rise synchronously. When the top block 8 is just connected to the lifting plate 10, the positioning plate 6 is pressed against the dividing plate 15, that is, the limiting protrusion 7 is connected to the corresponding positioning groove 17, thereby realizing the positioning of the dividing plate 15, improving the stability of the dividing plate 15, making the steering wheel nut rise steadily, the top block 8 continues to rise, and the position of the positioning plate 6 remains unchanged, the steering wheel nut gradually rises, and the robot arm is convenient to grab it. The operation is safe, reliable, flexible and convenient.

[0027] The push rod 5 is provided with a slide groove 20, and a guide column 22 is installed in the slide groove 20. The guide column 22 plays a good guiding role on the positioning plate 6 to prevent the limit protrusion 7 from being misaligned with the corresponding positioning groove 17. The guide column 22 is slidably connected with a sliding block 21, and the sliding block 21 is fixedly connected to the positioning plate 6. The sliding block 21 is connected with a spring 23 for driving the positioning plate 6 to move toward the indexing plate 15. When the top block 8 lifts the steering wheel connecting nut, the positioning plate 6 is pressed against the indexing plate 15. As the top block 8 continues to rise, the positioning plate 6 slides along the height direction of the push rod 5, that is, the sliding block 21 moves downward, the spring 23 is gradually compressed, and the thrust applied to the positioning plate 6 gradually increases, thereby improving the stability of the connection between the positioning plate 6 and the indexing plate 15 and providing good support for the indexing plate 15.

[0028] The sliding block 21 is slidably connected to the sliding groove 20 .

[0029] A limiting protrusion 7 is installed on the top of the positioning plate 6. There are usually two limiting protrusions 7, which are arranged opposite to each other. The limiting protrusion 7 matches the positioning groove 17 arranged at the bottom of the dividing plate 15. There are six groups of positioning grooves 17, each group corresponds to a corresponding positioning tray 16. When the dividing plate 15 is in the positioning state, the limiting protrusion 7 is connected to the positioning groove 17, that is, the dividing plate 15 cannot rotate.

[0030] The limiting frame 11 includes at least three fixing rods, and a plurality of lifting plates 10 are connected to the top of the limiting frame 11. The fixing rods are used to guide the lifting plates 10. When a plurality of steering wheel nuts are stacked together, the fixing rods are aligned to prevent misalignment. The lifting plates 10 are used to support the steering wheel nuts. When the steering wheel nuts rise, the top block 8 is lifted up from the lifting plates 10.

[0031] A positioning tray 16 for positioning the fixed rod is connected to the bottom of the dividing plate 15. A through hole 18 is provided at the center of the positioning tray 16. When the lifting plate 10 is lifted up, the top block 8 passes through the through hole 18. The positioning tray 16 is connected to the fixed rod by bolts. The positioning tray 16 is provided with three mounting holes 19 with adjacent angles of 120 degrees. The bottom of the fixed rod passes through the mounting holes 19 and is locked with bolts, so that the positioning tray 16 can be easily removed and replaced with positioning trays 16 with different diameters. That is, the size of the limit frame 11 can be changed, which is suitable for different types of steering wheel nut guide limit.

[0032] The lifting plate 10 is provided with a guide hole 9 which matches the fixing rod. When the lifting plate 10 rises, the fixing rod slides in the guide hole 9.

[0033] The center of the indexing plate 15 is connected to the sensing rod 12, that is, the indexing plate 15 is rotatably connected to the sensing rod 12, and the rotation of the indexing plate 15 cannot drive the sensing rod 12 to rotate. The sensing rod 12 is in a positioning state, and the top of the sensing rod 12 is connected to a probe 13, which is electrically connected to a control panel 14 connected to the top of the support platform 2. The direction of the probe 13 is consistent with the direction of the control panel 14. When the probe 13 detects that there is no steering wheel nut in front, the electric cylinder 4 continues to drive the push rod 5 to rise, and the superimposed steering wheel nut continues to rise to a suitable height, which is convenient for the robot arm to grab.

[0034] A support frame 1 is installed at the bottom of the support platform 2. The electric cylinder 4 is fixedly connected to a support plate 3 connected to the support frame 1. The support plate 3 provides good support for the electric cylinder 4 and improves the stability of the electric cylinder 4.

[0035] Working principle: Multiple steering wheel connecting nuts are stacked on six limit frames 11, and the motor 24 drives the indexing plate 15 to rotate to a suitable angle, so that the probe 13 is facing the corresponding limit frame 11, and the electric cylinder 4 drives the push rod 5 to rise, that is, the positioning plate 6 and the top block 8 rise synchronously. When the top block 8 is just connected to the lifting plate 10, the positioning plate 6 is pressed against the indexing plate 15, that is, the limiting protrusion 7 is connected to the corresponding positioning groove 17, so as to realize the positioning of the indexing plate 15 and prevent the rotation from loosening. The electric cylinder 4 continues to drive the top block 8 to rise, and the steering wheel connecting nut can be lifted up to a suitable height, so that it is convenient for the mechanical arm to grab it, and the operation is safe and reliable. During the rising process of the top block 8, the positioning plate 6 moves downward relative to the push rod 5, that is, the sliding block 21 slides in the slide groove 20, and the spring 23 is gradually compressed, and the thrust applied to the positioning plate 6 gradually increases, thereby improving the stability of the connection between the positioning plate 6 and the indexing plate 15 and providing good support for the indexing plate 15. When the probe 13 detects that there is no steering wheel nut in front, the electric cylinder 4 continues to drive the push rod 5 to rise, and the superimposed steering wheel nut continues to rise to a suitable height, and the mechanical arm grabs it. When the probe 13 detects the lifting plate 10, it means that the nuts in the corresponding limit frame 11 have been taken out, the electric cylinder 4 drives the positioning plate 6 and the top block 8 to return to their positions, and the motor 24 drives the indexing plate 15 to rotate 60 degrees, so that the next limit frame 11 is aligned with the probe 13.
