[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. First, the wheel rim enters the fixture assembly in the rotating disk from the second feed port, and the wheel rim is fixed by the fixture assembly. Then the steel sleeve enters from the first feed port above. Since the laser sensor has scanned the information of the wheel rim in advance and generated a three-dimensional image of the wheel rim, the steel sleeve enters from the first feed port until it contacts the inner wall surface of the blocking plate. The support assembly assists in supporting the steel sleeve, and then the corresponding clamping plate clamps and fixes the steel sleeve through the driving of the bidirectional lead screw. The laser sensor emits a laser beam again and scans the surface of the wheel rim (including the bolt holes). The identified bolt holes are compared with the bolt hole positions of the wheel rim.

[0021] 2. After the wheel rim enters through the second feed port, it contacts the fitting block. Since the clamping claws of different lengths are adjacent to the end of the guide plate, the wheel rim and the steel sleeve smoothly enter the inner side of the clamp assembly and the blocking plate, which facilitates the initial pressing of the steel sleeve and the wheel rim. Then, the wheel rim is fixed by the clamping claws to ensure the stability of the wheel rim and the steel sleeve when they are pressed in.

[0022] 3. Each time the rotating disk is installed into the wheel rim, it rotates 90 degrees counterclockwise. At this time, the reciprocating positioning cylinder starts to work, that is, the extended end of the reciprocating positioning cylinder pushes the insert block into the corresponding positioning cylinder, thereby limiting the position of the rotating disk to avoid shaking, further improving the stability of the steel sleeve when pressed into the wheel rim, and avoiding pressing errors.

The top surface of the inlet 2 is flush with the lower plate 16 that supports the steel sleeve, and the lower surface of the upper plate 14 is installed with a deflection pressing component for correcting the angle of the steel sleeve, and the top surface of the lower plate 16 is installed with a blocking plate 15 with an arc structure on the side away from the feed inlet 2, and the interior of the lower plate 16 is adapted to be installed with a supporting component; the deflection pressing component includes a laser sensor 21 installed on the bottom surface of the upper plate 14, and a pressure ring block 23 for pressing the steel sleeve is installed under the upper plate 14 for lifting and lowering. Two propulsion cylinders 22 are installed on the top surface of the upper plate 14, and both sides of the top surface of the pressure ring block 23 are fixed to the push end of the propulsion cylinder 22;A fixing rod 30 is fixed in the middle of the top surface of the pressure ring block 23, and two limiting arc grooves 32 are symmetrically penetrated on the surface of the pressure ring block 23. A servo motor 36 is installed in the middle of the bottom surface of the fixing rod 30. The driving end of the servo motor 36 is installed with a mounting seat 31 sliding in the limiting arc groove 32. The bottom surface of the mounting seat 31 is provided with two driving grooves 34. A bidirectional lead screw 35 driven by a dual-axis motor is rotatably installed inside each driving groove 34. The outside of each bidirectional lead screw 35 is threadedly sleeved with a clamping plate 33 that slides along the driving groove 34 and is in close contact with the outside of the steel sleeve. In the initial state, the pressure ring block 2 3 is located at the top of the upper plate 14, and the two clamps 33 are in an open state. When in use, a clamp assembly in the rotating disk 7 is opposite to the feed port 2 5, and the wheel rim enters the clamp assembly in the rotating disk 7 from the feed port 2 5. The wheel rim (including the bolt hole) is fixed by the clamp assembly, and then the steel sleeve enters from the upper feed port 12. Since the laser sensor 21 has scanned the information of the wheel rim in advance to generate a three-dimensional image of the wheel rim, the steel sleeve enters from the feed port 12 until it contacts the inner wall surface of the blocking plate 15, and the support assembly assists the steel sleeve, and then the corresponding The clamping plate 33 clamps the steel sleeve and fixes it. The laser sensor 21 emits a laser beam again and scans the surface of the wheel rim (including the bolt holes). The sensor receives the reflected light and calculates the distance information, automatically generates a three-dimensional image of the steel sleeve, identifies the position and shape of the bolt holes in the three-dimensional image, and compares the identified bolt holes with the bolt hole positions of the wheel rim. According to the comparison results, if there are differences, the servo motor 36 is automatically controlled to drive the mounting seat 31 to rotate in the limiting arc groove 32, thereby changing the placement angle of the steel sleeve, adjusting the pressing angle of the steel sleeve and the wheel rim, realizing automatic alignment, and improving the pressing accuracy. , thereby improving the quality of pressing. During pressing, the two propulsion cylinders 22 synchronously push the ring block 23 downward to press the steel sleeve. At this time, the support assembly is opened to facilitate the pressing of the steel sleeve. After the steel sleeve and the wheel rim are pressed in, the rotating disk 7 rotates 90 degrees counterclockwise, and the remaining clamp components are loaded into the wheel rim in turn, and the steel sleeve is initially pressed in, until the rotating disk 7 rotates to the position of the discharge port 4, and starts pressing in. After the pressing is completed, it rotates 90 degrees counterclockwise, and the pressing position reaches the position of the feed port 1 2 and the feed port 2 5 again, realizing a cycle, improving the pressing efficiency of the steel sleeve and the wheel rim, and having a high degree of automation. ;

[0034] See also Figure 4As shown, the support assembly includes a drop groove 17 provided on the lower plate 16, and the drop groove 17 is used for the steel sleeve to drop. The inner wall surfaces on both sides of the drop groove 17 are provided with a reset cavity 28 inwardly, and a stroke cylinder 29 is installed inside each reset cavity 28. The pushing end of each stroke cylinder 29 is fixedly connected with a support block 18. The ends of the two support blocks 18 are plugged and arranged. The support blocks 18 are semicircular structures. Initially, the two support blocks 18 are connected together and support the steel sleeve, and the arc-shaped blocking plate 1 5 blocks the transmitted steel sleeve, which is now located at the center of the support block 18. The steel sleeve is clamped and fixed by two movable clamping plates 33, and then the clamping plates 33 drive the steel sleeve to move downward through the downward pressure of the propulsion cylinder 22. The clamping plates 33 and the pressure ring block 23 all pass through the inside of the blanking trough 17. After the steel sleeve is fitted with the wheel rim, the two clamping plates 33 retract, and the propulsion cylinder 22 continues to press downward to achieve the initial press-fitting of the steel sleeve and the wheel rim, thereby avoiding the steel sleeve from falling when rotating with the rotating disk 7.

[0035] See also Figure 2 As shown, each clamp assembly includes two clamping jaws 9 of different lengths. The clamp assembly is an electric clamp. A fitting block 8 in contact with the outer surface of the rim is provided on the side of the clamping jaw 9 away from the feed port 2 5. After the rim enters through the feed port 2 5, it fits and contacts with the fitting block 8, and then the clamping jaw 9 is used to fix the rim to ensure the stability of the rim and the steel sleeve when pressed in.

[0036] See also Figure 4 As shown, a sliding groove 24 is provided on the surface of the rotating disk 7, and a push cylinder 25 is installed on the side of the bottom surface of the rotating disk 7 adjacent to the sliding groove 24. A push block 26 is slidably installed inside the sliding groove 24. The top of the push block 26 is fixed to the bottom surface of the bonding block 8, and the bonding block 8 is inclined. Figure 2 As shown, initially, the pushing cylinder 25 does not work. After the steel sleeve is pressed into the wheel rim, the pushing cylinder 25 pushes the inclined fitting block 8 to move, and the fitting block 8 smoothly pushes the wheel rim pressed into the steel sleeve out of the discharge port 4, thereby completing the pushing work.

[0037] See also Figure 2 As shown, the inner wall of the material rack 3 is provided with guide plates 6 for guiding the wheel rim and the steel sleeve at the ends near the feed port 2 5 and the feed port 1 2, and the ends of the clamping jaws 9 are adjacent to the ends of the guide plates 6. The wheel rim and the steel sleeve pass through the feed port 2 5 and the feed port 1 2 in sequence. Since the clamping jaws 9 of different lengths are adjacent to the ends of the guide plates 6, the wheel rim and the steel sleeve smoothly enter the inner side of the clamp assembly and the sealing plate 15, thereby facilitating the initial pressing of the steel sleeve and the wheel rim.

[0038] See also Figure 3As shown, a fixed plate 10 is fixedly installed at the bottom of the inner cavity of the pressing chamber 1 below the rotating disk 7, a reciprocating positioning cylinder 11 is installed on the bottom surface of the fixed plate 10, and a rotating motor for driving the rotating disk 7 to rotate is installed in the middle of the bottom surface of the fixed plate 10, and a plurality of positioning cylinders 13 are installed at the edge of the lower surface of the rotating disk 7, and the plurality of positioning cylinders 13 are arranged in a ring shape, and an insert block 12 inserted into the inside of the positioning cylinder 13 is fixed at the pushing end of the reciprocating positioning cylinder 11. Every time the rotating disk 7 rotates 90 degrees, the reciprocating positioning cylinder 11 starts to work, that is, the extended end of the reciprocating positioning cylinder 11 pushes the insert block 12 into the corresponding positioning cylinder 13, thereby limiting and fixing the position of the rotating disk 7 to avoid shaking and further improve the stability of its pressing.

[0039] See also Figure 1 and Figure 2 As shown, the outer surface of the pressing chamber 1 is provided with a discharge port 4 on one side of the feed port 2 5, and the feed port 2 5 and the discharge port 4 are symmetrically arranged about the center line of the material rack 3, and the material rack 3 is provided with a conveyor belt flush with the surfaces of the feed port 1 2, the feed port 2 5 and the discharge port 4, and the movement direction of the conveyor belt on the side of the opening of the feed port 2 5 and the feed port 1 2 is opposite to that of the conveyor belt on the side of the opening of the discharge port 4, that is, the material is fed through the conveyor belts on the side of the feed port 2 5 and the feed port 1 2, while the conveyor belt on the side of the discharge port 4 is used for discharging the material; a pressing plate for pressing the steel sleeve into the wheel rim is arranged inside the pressing chamber 1, and the pressing plate is driven by the hydraulic cylinder at the top of the pressing chamber 1, and the end of the pressing plate is close to the discharge port 4, that is, the pressing of the steel sleeve and the wheel rim is completed on the side close to the discharge port 4, that is, the formal pressing work begins when the rotating disk 7 rotates to the discharge port 4.

[0040] When the present invention is in use, first, the wheel rim enters the clamp assembly in the rotating disk 7 from the feed port 2 5, and the wheel rim is fixed by the clamp assembly, and then the steel sleeve enters from the upper feed port 1 2. Since the laser sensor 21 has previously scanned the information of the wheel rim to generate a three-dimensional image of the wheel rim, the steel sleeve enters from the feed port 1 2 until it contacts the inner wall surface of the blocking plate 15, and the steel sleeve is auxiliary supported by the support assembly. Then, the corresponding clamping plate 33 is driven by the bidirectional lead screw 35 to clamp and fix the steel sleeve. The laser sensor 21 is used to emit a laser beam again and scan the surface of the wheel rim (including the bolt holes). The identified bolt holes are compared with the bolt hole positions of the wheel rim. According to the comparison results, if there is a difference, the servo motor 36 is automatically controlled to drive the mounting seat 31 in the limit arc groove 3 2 rotates and rotates, thereby changing the placement angle of the steel sleeve, adjusting the pressing angle of the steel sleeve and the wheel rim, realizing automatic alignment, improving the pressing accuracy, reducing the pressing error, and thus improving the pressing quality. During pressing, the two propulsion cylinders 22 synchronously push the pressure ring block 23 downward to press the steel sleeve. At this time, the support assembly is opened to facilitate the pressing action of the steel sleeve. After the steel sleeve and the wheel rim are pressed in, the rotating disk 7 rotates 90 degrees counterclockwise, and the remaining clamp assemblies are sequentially loaded into the wheel rim, and the steel sleeve is preliminarily pressed in until the rotating disk 7 rotates 270 degrees to the position of the discharge port 4, and then starts pressing in. After the pressing is completed, it rotates 90 degrees counterclockwise, and the pressing position reaches the position of the feed port 1 2 and the feed port 2 5 again, realizing a periodic cycle, improving the pressing efficiency of the steel sleeve and the wheel rim, and having a high degree of automation;

[0041] After the wheel rim enters through the feed port 2 5, it contacts with the fitting block 8. Since the clamping claws 9 of different lengths are adjacent to the end of the guide plate 6, the wheel rim and the steel sleeve smoothly enter the inner side of the clamp assembly and the blocking plate 15, thereby facilitating the initial pressing of the steel sleeve and the wheel rim. Then, the wheel rim is fixed by the clamping claws 9 to ensure the stability of the wheel rim and the steel sleeve when they are pressed in.

[0042] Each time the rotating disk 7 is installed into the wheel rim, it rotates 90 degrees counterclockwise. At this time, the reciprocating positioning cylinder 11 starts to work, that is, the extended end of the reciprocating positioning cylinder 11 pushes the insert block 12 into the corresponding positioning tube 13, thereby limiting and fixing the position of the rotating disk 7 to avoid shaking, further improving the stability of the steel sleeve when pressed into the wheel rim, and avoiding pressing errors.
