[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment

[0022] Please refer to Figures 1 to 4 , which is an embodiment of the present invention. This embodiment provides a technical solution: a rotating mechanism of an assembled automobile wheel hub spinning press, including

[0023] A motor 9 installed inside the machine table 8, a rotary table 1 rotatably installed on the top surface of the machine table 8 and connected to the output end of the motor 9, a lower pressing plate 4 installed on the top of the rotary table 1, and a bottom swivel base 2 welded and fixed to the bottom surface of the lower pressing plate 4. After the motor 9 is started later, it can drive the rotary table 1 to rotate. The rotary table 1 then drives the bottom swivel base 2 and the lower pressing plate 4 to rotate through two driving plug posts 3, and can drive the wheel hub placed on the top of the lower pressing plate 4 to rotate for processing;

[0024] And two driving plug posts 3 welded and fixed to the top surface of the rotary table 1. A perforation B31 is provided through the surface of the driving plug post 3. Two slots 21 for inserting the driving plug posts 3 are provided on the bottom surface of the bottom swivel base 2. A perforation A22 penetrating through the two slots 21 is provided on the circumferential surface of the bottom swivel base 2. After the two driving plug posts 3 are inserted into the slots 21, it can be ensured that when the rotary table 1 rotates, it will drive the bottom swivel base 2 to rotate together through the two driving plug posts 3;

[0025] And a through rod 5. A perforation B31 corresponding to the through rod 5 is provided through the surface of the driving plug post 3. The through rod 5 horizontally penetrates the bottom swivel base 2 through the perforation A22, and the through rod 5 penetrates the driving plug post 3 through the perforation B31. The penetrated through rod 5 can plug the bottom swivel base 2 and the driving plug post 3 together;

[0026] And two limit blocks 6 are arranged on the surface of the rotary table 1, and the top ends of the limit blocks 6 are located on one side of the through rod 5. The limit blocks 6 on both sides can play a role in stably limiting the through rod 5, ensuring the insertion stability between the bottom swivel base 2 and the driving plug post 3.

[0027] Among them, T-shaped side grooves A11 are formed on both side surfaces of the rotary table 1, and a spring 12 and a T-shaped side block A13 are installed in the T-shaped side grooves A11. The end of the T-shaped side block A13 extends to the surface of the rotary table 1 and is fixed to the limit block 6. Under the push of the spring 12, the T-shaped side block A13 can stably abut against the inner wall of the top end of the T-shaped side groove A11 during daily use, and the top end of the limit block 6 can always be located on one side of the through rod 5, ensuring the limiting stability of the through rod 5. It should be noted that during the daily operation of the spinning machine, the limit block 6 will not be subjected to any force in the vertical direction and will only generate a centrifugal force in the horizontal direction due to the rotation of the rotary table 1. Therefore, although the limit block 6 is elastically installed through the spring, it can still stably block the through rod 5, ensuring the assembly stability of the entire rotating mechanism; if the bottom swivel base 2 and the driving plug post 3 need to be disassembled in the later stage to realize the disassembly and replacement of the lower pressing plate 4, only need to press down the limit block 6 forcefully, so that the T-shaped side block A13 slides down and compresses the spring 12, then the limit block 6 can be smoothly moved down to release the block on the through rod 5. At this time, the through rod 5 can be pulled out to realize the rapid removal of the lower pressing plate 4. Similarly, during the assembly of the lower pressing plate 4 later, first press down the limit block 6 forcefully to insert the through rod 5 into the through hole A22 and the through hole B31, and then release the limit block 6, so that the limit block 6 moves up and rebounds to clamp the through rod 5 between the two limit blocks 6 again, ensuring the assembly firmness between the bottom swivel base 2 and the driving plug post 3.

[0028] Among them, a cylindrical groove is formed on the bottom surface of the T-shaped side block A13, and the top end of the spring 12 is inserted into the cylindrical groove, which can realize the limitation of the spring 12 to prevent the spring 12 from shifting in the T-shaped side groove A11. The bottom end of the spring 12 is fixed to the inner wall of the bottom end of the T-shaped side groove A11, further ensuring the installation stability of the spring 12.

[0029] Among them, an anti-accidental touch block 7 is also installed on the side of the limit block 6, and a liftable connecting structure is provided between the anti-accidental touch block 7 and the limit block 6, the liftable connecting structure includes a T-shaped side groove B61 opened on the side of the limit block 6 and a T-shaped side block B71 fixed on the side of the anti-accidental touch block 7, the T-shaped side block B71 is slidably located in the T-shaped side groove B61, and the liftable connecting structure also includes a rubber seat 62 embedded in the inner wall of the two ends of the T-shaped side groove B61, the surface of the rubber seat 62 is provided with a positioning protrusion 63, the surface of the T-shaped side block B71 is provided with a positioning groove 72 corresponding to the positioning protrusion 63, one of the positioning protrusions 63 is squeezed into the positioning groove 72, and the T-shaped side block B71 and the anti-accidental touch block 7 can be limited during daily use to prevent the anti-accidental touch block 7 and the limit block 6 from easily moving up and down due to accidental contact with foreign objects. When the locking cam 62 is in the locked state, the locking cam 63 is in the locked state, and the locking cam 64 is in the locked state, so that the locking cam 62 is locked and the locking cam 64 is in the locked state.

[0030] The rubber seat 62 and the positioning protrusion 63 are an integrated structure, both of which are made of rubber material and will undergo elastic deformation when squeezed.

[0031] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
