[0030] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings, so that those skilled in the art can implement it based on the description.

[0031] See Figures 1-11 As shown in the figure, this embodiment of the invention discloses a ball-feeding and pressing device, including a ball-feeding mechanism 1 and a pressing mechanism 2. The ball-feeding and pressing mechanism 1 includes a vibrating plate 11 and a ball-feeding component connected to the outlet of the vibrating plate 11. The pressing mechanism 2 includes a secondary feeding component, a ball-pressing component, and a product-carrying fixture (not shown in the figure). The secondary feeding component is connected to the ball-feeding component. The ball-pressing component and the product-carrying fixture are located above and below the pressing powder component, respectively. The pressing and pressing component is used to receive multiple balls distributed by the ball-feeding component and send these balls to contact the wheel hub product K located on the product-carrying fixture according to a set path. The ball-pressing component is used to press the balls and the wheel hub product into place.

[0032] The ball-blowing and material-distributing assembly includes a connecting block 12, a first material-distributing plate 13, a first material-leaking plate 14, and a first driving member 15. The end of the connecting block 12 is fixed to the material-leaking plate, and a groove is provided at the bottom end of the connecting block 12. A sliding groove is formed between the groove and the upper end face of the material-leaking plate, allowing the first material-distributing plate 13 to move laterally. The first driving member 15 is used to drive the first material-distributing plate 13 to move. An air inlet pipe 16 is provided in the connecting block 12. A plurality of first material-distributing holes 131 are provided on the first material-distributing plate 13, and a plurality of first material-leaking holes 141 are provided on the first material-leaking plate 14. When the first material-distributing plate 13 moves to a set position, the plurality of first material-distributing holes 131 and the plurality of first material-leaking holes 141 are aligned one by one, and the air inlet pipe 16 is connected to the first material-distributing holes 131 and the first material-leaking holes 141.

[0033] The vibratory plate 11 is connected to the ball blowing and distributing assembly through a guide fixture. The guide fixture includes multiple guide tubes 17. The top ends of the multiple guide tubes 17 are connected to the outlet of the vibratory plate 11, and the bottom ends of the multiple guide tubes 17 are inserted into the connecting block 12 and connected to the first distributing plate 13.

[0034] The working principle of the ball blowing and distributing mechanism 1 is as follows:

[0035] The vibrating plate 11 vibrates and outputs the small balls in sequence into the guide tube 17. The balls then fall from the guide tube 17 into the first distribution hole 131 on the first distribution plate 13 until the bottom of the first distribution hole 131. At this time, the first distribution hole 131 is not aligned with the first leakage hole 141. Then, the first distribution cylinder drives the first distribution plate 13 to move to the set position. At this time, the multiple first distribution holes 131 are aligned with the multiple first leakage holes 141 one by one. The small balls fall from the bottom of the first distribution hole 131 into the first leakage hole 141. The gas in the air inlet pipe 16 blows the small balls into the secondary distribution component of the pressing mechanism 2.

[0036] The secondary material distribution assembly includes a mounting plate 21, a connecting seat 22 mounted on the mounting plate 21, a second material distribution plate 23, a second material leakage plate 24, and a second driving member 25. A partial area of ​​the bottom of the connecting seat 22 is fixed to the second material leakage plate 24. The top of the second material leakage plate 24 has a groove, and a sliding groove is formed between the groove and the bottom end face of the connecting seat 22 to allow the second material distribution plate 23 to move laterally. The connecting seat 22 is provided with multiple material distribution channels 221 that allow small balls to slide into the second material distribution plate 23. The material distribution channels 221 are connected to the first material leakage hole 141. The second driving member 25 is used to drive the second material distribution plate 23 to move. The second material distribution plate 23 is provided with multiple second material distribution holes 231, and the second material leakage plate 24 is provided with multiple second material leakage holes 241. When the second material distribution plate 23 moves to a set position, the multiple second material distribution holes 231 and the multiple second material leakage holes 241 are aligned one by one.

[0037] The ball-pressing assembly includes a gas-hydraulic booster cylinder 26, a connecting plate 27 connected to the telescopic rod of the gas-hydraulic booster cylinder 26, a small cylinder 28 whose cylinder body is fixed on the connecting plate 27, a push rod cylinder 29, and multiple push rods 291. The telescopic rod of the small cylinder 28 is fixedly connected to the mounting plate 21. Multiple push rods 291 are disposed inside the push rod cylinder 29. The bottom end of the push rod cylinder 29 is fixedly connected to the bottom end face of the connecting plate 27, and the push rod cylinder 29 is located above the connecting seat 22. The connecting seat 22 is provided with multiple clearance holes 22 for multiple push rods 291 to pass through. 2. The material distribution channel 221 is inclined to the clearance hole 222 (the inclined material distribution channel 221 and the vertical clearance hole 222 form a Y-shaped channel structure). The end of the material distribution channel 221 is connected to the clearance hole 222. The ball reaches the clearance hole 222 through the material distribution channel 221 and then falls into the second material distribution hole 231 through the clearance hole 222. When the small cylinder 28 retracts, the product support fixture rises to the set height accordingly. Multiple push rods 291 pass through the clearance hole 222, the second material distribution hole 231 and the second leakage hole 241 to contact the ball.

[0038] The push rod cylinder 29 is also equipped with multiple pressure sensors 3 and displacement sensors 4. The multiple pressure sensors 3 are in contact with the top ends of multiple push rods 291. The pressure sensors 3 are used to monitor the force of the ball pressing into the tooling, and the displacement sensors 4 are used to monitor the depth of the ball pressing into the tooling.

[0039] The secondary material distribution assembly also includes a C-shaped bracket 5 and a guide rail 6 vertically mounted on the C-shaped bracket 5, with the mounting plate 21 slidably connected to the guide rail 6. When the small cylinder 28 retracts, the mounting plate 21 moves, and the guide rail 6 acts as a guide.

[0040] The working principle of the pressing mechanism 2 is as follows:

[0041] The air inlet pipe 16 of the ball blowing and distributing assembly blows the ball into the distributing channel 221 in the connecting seat 22. The ball then enters the clearance hole 222 from the distributing channel 221, and then enters the second distributing hole 231 on the second distributing plate 23 until the bottom of the second distributing hole 231. Then, the second distributing cylinder drives the second distributing plate 23 to move to the set position. At this time, the multiple second distributing holes 231 are aligned with the multiple second leakage holes 241 one by one. The ball falls from the bottom of the second distributing hole 231 into the second leakage hole 241 until it finally falls onto the wheel product on the product carrier fixture.

[0042] When the telescopic rod of the small cylinder 28 retracts, the mounting plate 21 rises (the connecting seat 22, the second material distribution plate 23, and the second material leakage plate 24 rise together), and the product bearing fixture rises to the set height accordingly. At this time, multiple push rods 291 extend into the clearance hole 222, the second material distribution hole 231, and the second material leakage hole 241 and their bottoms contact the small ball.

[0043] When the telescopic rod of the gas-liquid booster cylinder 26 extends, multiple push rods 291 press down on multiple small balls, thereby pressing the small balls into the wheel hub product.

[0044] Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
