Description

Technical Field

[0001] This invention relates to the field of wheel hub manufacturing technology, and in particular to a tooling adjustment device for drying wheel hubs. Background Technology

[0002] In the automotive wheel manufacturing process, drying is a crucial step connecting cleaning, painting, and other processes. Its core objective is to quickly remove residual moisture and oil from the surface and interior of the wheel hub, providing a dry and clean workpiece surface for subsequent painting, electroplating, and other processes. With the increasing demand for lightweight and high-precision wheels in new energy vehicles, the application of lightweight wheels such as aluminum alloys is becoming more and more widespread. These wheels often have streamlined arc-shaped surfaces and thin walls, which places stringent requirements on the temperature uniformity and clamping stability of the drying process.

[0003] Patent CN218475551U discloses a paint drying device for automobile wheel hubs, which solves the problem of poor reliability in the wheel hub clamping function of existing wheel hub painting equipment. This paint drying device includes a base and clamping and drying components mounted on the base. The clamping component includes two sets of inner supports symmetrically fixed on the base, with two sets of clamping hydraulic cylinders symmetrically mounted on the two sets of inner supports. Clamping bodies are provided at the ends of the hydraulic rods of the clamping hydraulic cylinders, forming a clamping station for clamping the wheel hub between the two sets of clamping bodies. The clamping body includes an arc-shaped clamping plate made of a soft material and a clamping connecting rod fixed in the middle of the outer arc surface of the arc-shaped clamping plate for engaging with the hydraulic rods of the clamping hydraulic cylinders. Several elastic contact heads with elasticity are provided on the inner arc surface of the arc-shaped clamping plate. Compared with the prior art, this paint drying device has higher clamping strength and reliability for the wheel hub, and is easier to manufacture and implement.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] When fixing the wheel hub, radial clamping is achieved only by driving the arc-shaped clamping plates with hydraulic cylinders on both sides, lacking axial clamping and limiting. During the drying process, if the wheel hub needs to be rotated or its angle adjusted, axial movement of the wheel hub is likely to occur, causing the wheel hub to collide with the drying equipment and resulting in surface scratches. Secondly, the drying angle adjustment is limited, which can easily create drying dead zones and cannot achieve dynamic angle changes during the drying process. In addition, most devices can only achieve rotation of the wheel hub in one direction and cannot combine with oscillation to achieve three-dimensional dynamic drying, resulting in uneven heating of the wheel hub surface. Local over-drying can easily cause oxidation and discoloration, while local incomplete drying will affect the adhesion of subsequent coatings. To solve the above problems, we propose a tooling adjustment device for wheel hub drying. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This tooling adjustment device for drying wheel hubs first fixes the inner ring of the wheel hub through a radial clamping mechanism during the wheel hub clamping step, and then clamps the top of the wheel hub from both the center and the edge through an axial double-pressure structure, forming a multi-dimensional clamping effect. This clamping method can not only adapt to wheel hubs of different specifications without frequent replacement of parts, but also ensures that the wheel hub remains stable during subsequent lifting, rotating, and swaying steps, without radial movement or axial loosening. It effectively avoids surface scratches caused by collisions between the wheel hub and device components, reduces the risk of workpiece scrapping, and also provides a stable foundation for subsequent uniform drying.

[0020] 2. This wheel hub drying fixture adjustment device, during the drying process, precisely delivers the wheel hub to the appropriate drying height through lifting adjustment, and then ensures uniform heating around the circumference of the wheel hub through rotation adjustment. Simultaneously, the swinging motion drives the jet structure to move synchronously. During the swinging process, the jet structure automatically generates a stable airflow and sprays air onto the surface of the wheel hub. The airflow can cover areas that are difficult to reach with traditional drying methods, such as the inner side and corners of the wheel hub, achieving drying without dead angles. This combination of precise adjustment, dynamic jetting, and rotational swinging, compared with the traditional fixed drying mode, can shorten the drying time and avoid the problems of incomplete or over-drying of localized areas of the wheel hub, significantly improving the consistency of drying efficiency and drying quality.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figure 1 - Figure 8As shown, a tooling adjustment device for drying wheel hubs includes a base plate 1 and a steering mechanism 9. A cylinder 13 is provided on the bottom side wall of the base plate 1, a lifting plate 3 is provided on the output end of the cylinder 13, a first motor 2 is provided on the bottom side wall of the lifting plate 3, and multiple support columns are provided on the top of the lifting plate 3, with a sensor mounting plate 12 provided on the top of the support columns.

[0032] In this embodiment, the steering mechanism 9 includes a connecting plate 91 detachably connected to the top of the top plate 10. A connecting sleeve 92 is provided on the top side wall of the connecting plate 91. A positioning hole is opened through the bottom side wall of the connecting sleeve 92 through the connecting plate 91. Two support plates 901 are provided on the top side wall of the connecting plate 91. A rocker arm 902 is rotatably connected to the opposite side wall of each of the two support plates 901. A rocker arm 907 is rotatably connected to both ends of each of the two rocker arms 902. A piston 909 is provided on the bottom side wall of the rocker arm 907. Two air chambers 908 are provided on the bottom side wall of the connecting plate 91. A first one-way valve 9091 is provided on the bottom side wall of each of the two air chambers 908. A hole is opened on the outer side wall of each of the two air chambers 908, and a second one-way valve 9092 is provided on the inner side wall of the hole. An air transmission pipe 9093 is provided on the outer side wall of each of the two air chambers 908. Two positioning holes are opened on the top side walls of each of the two rocker arms 902. Two fixed plates 99 are fixedly connected to two side walls of each other, and connecting rods 98 are fixedly connected to the outer walls of the connecting rods 98. A rotating cylinder 97 is rotatably connected to the outer wall of the connecting sleeve 92. A second motor 93 is provided on the top side wall of the connecting sleeve 92. A swing bracket 94 is provided at the output end of the second motor 93. A universal ball joint 95 is rotatably connected to the top side wall of the swing bracket 94. A U-shaped bracket 96 is provided at the other end of the universal ball joint 95. The two ends of the U-shaped bracket 96 are fixedly connected to the outer walls of the two rotating cylinders 97 respectively. The same first mounting plate 903 is provided on the top side wall of the two fixed plates 99. An air collecting cylinder 904 is provided on the top side wall of the first mounting plate 903. The other ends of the two air transmission pipes 9093 are fixedly connected to the inside of the air collecting cylinder 904. An air outlet cylinder 905 is provided on the top side wall of the air collecting cylinder 904. Multiple air jets 906 are provided on the outer wall of the air outlet cylinder 905. A clamping mechanism 910 is provided on the top side wall of the air outlet cylinder 905.

[0033] Specifically, the second motor 93 is started, and the output of the motor drives the swing bracket 94 to rotate. The swing bracket 94 drives the U-shaped bracket 96 to move flexibly through the universal ball 95. The U-shaped bracket 96 is fixedly connected to the rotating drum 97. The rotating drum 97 drives the fixed plate 99 and the swing rod 902 to reciprocate around the rotation axis of the support plate 901 through the connecting rod 98. When the swing rod 902 swings, the rocker arms 907 at both ends move accordingly, driving the piston 909 to reciprocate linearly within the air chamber 908. When the piston 909 moves upward, the air pressure inside the air chamber 908 decreases, the first one-way valve 9091 opens, and external air is drawn into the air chamber 908. When the piston 909 moves downward, the air chamber 908... As the internal air pressure increases, the first one-way valve 9091 closes and the second one-way valve 9092 opens. Compressed air is then transported to the air collection cylinder 904 via two air transmission pipes 9093. After the air collection cylinder 904 stabilizes the air pressure, it is transported to the air outlet cylinder 905. Finally, multiple jet nozzles 906 on the outside of the air outlet cylinder 905 spray air evenly onto the surface of the wheel hub. Combined with the external drying heat source, this accelerates the evaporation of moisture on the surface of the wheel hub. The swaying motion ensures that the jetting has no dead angles, resulting in more uniform drying. During the drying process, the first motor 2 starts intermittently, driving the rotating table 4 to rotate slowly, so that the wheel hub is heated evenly in the circumferential direction. At the same time, the second motor 93 continuously drives the steering mechanism 9, causing the wheel hub to sway back and forth. The jet nozzles 906 spray air synchronously with the swaying motion.

[0034] In this embodiment, the clamping mechanism 910 includes a second mounting plate 911 fixedly connected to the top side wall of the air outlet 905. The top side wall of the second mounting plate 911 is provided with a positioning block 912. The outer side wall of the positioning block 912 is provided with multiple holes, and the inner side wall of the corresponding holes is fixedly connected with a first electric telescopic rod 913. The telescopic ends of the multiple first electric telescopic rods 913 are provided with clamping plates 914. The top side wall of the positioning block 912 is provided with a second electric telescopic rod 915. The telescopic ends of the second electric telescopic rod 915 are provided with a first pressure plate 916. The two ends of the first pressure plate 916 are provided with third electric telescopic rods 917. The telescopic ends of the third electric telescopic rods 917 are provided with second pressure plates 918.

[0035] Specifically, the first electric telescopic rod 913 is activated, and its telescopic end pushes the clamping plate 914 to slowly expand outward until the outer wall of the clamping plate 914 is tightly fitted with the inner ring side wall of the wheel hub, thus achieving radial fixation of the wheel hub. The second electric telescopic rod 915 is then extended, and the first pressure plate 916 moves upward accordingly. Subsequently, the third electric telescopic rod 917 extends, pushing the two second pressure plates 918 to move outward. Then, the second electric telescopic rod 915 retracts, and the first pressure plate 916 moves downward accordingly until the bottom surface of the second pressure plate 918 is fitted with the center area of ​​the top surface of the wheel hub. After applying a preset pressure, the pressure is stopped, and the pressure plate is fitted with the edge area of ​​the top surface of the wheel hub.

[0036] In this embodiment, a planetary reducer is provided at the output end of the first motor 2, and a coupling 7 is provided at the output end of the planetary reducer. A connecting part 42 is fixedly connected to the other end of the coupling 7. A sensor plate mounting rod 41 is provided on the side wall of the other end of the connecting part 42, and a rotating table 4 is provided on the top side wall of the sensor plate mounting rod 41.

[0037] Specifically, the first motor 2 is started, and its output end is reduced by a planetary reducer and then drives the connecting part 42 to rotate through the coupling 7. The connecting part 42 drives the induction plate mounting rod 41 and the rotating table 4 to rotate synchronously.

[0038] In this embodiment, sensor brackets are provided on the four side walls of the sensor mounting plate 12, and a first sensor 5 is provided on one end of each sensor bracket. Multiple first sensing plates 6 are provided on the outer side wall of the sensing plate mounting rod 41, and the number of first sensing plates 6 is the same as the number of first sensors 5.

[0039] Specifically, during the rotation process, the first sensing plate 6 rotates with the sensing plate mounting rod 41. When a certain first sensing plate 6 is aligned with the first sensor 5 on the sensor mounting plate 12, the first sensor 5 sends a signal to the control system. The system determines whether the rotation angle meets the preset drying angle. If it does not meet the standard, it continues to control the first motor 2 to rotate until the rotating table 4 stops precisely at the target angle. The first motor 2 then stops, completing the rotation positioning, thereby enabling accurate position detection.

[0040] In this embodiment, four guide mechanisms 8 are provided on the bottom side wall of the base plate 1. Each guide mechanism 8 includes a guide post and a guide sleeve. One end of the guide post is connected to the lifting plate 3, and the guide sleeve is installed on the base plate 1. A top plate 10 is provided on the top side wall of the rotary table 4, and a positioning pin 11 is provided on the top plate 10.

[0041] Specifically, cylinder 13 pushes lifting plate 3 to move upward along guide column of guide mechanism 8, support column drives sensor mounting plate 12 to rise synchronously, and rotary table 4 moves upward with sensor mounting rod 41 and connecting part 42 until the hub on top plate 10 reaches the effective drying height of drying equipment.

[0042] It should be noted that this invention is a tooling adjustment device for drying wheel hubs. The user lifts the wheel hub to be dried using an external robotic arm, aligns the center hole of the wheel hub with the top of the positioning block 912, and slowly lowers the wheel hub until the inner bottom surface of the wheel hub is completely in contact with the top of the second mounting plate 911. The first electric telescopic rod 913 is activated, and its telescopic end pushes the clamping plate 914 to slowly expand outward until the outer wall of the clamping plate 914 is tightly in contact with the inner ring side wall of the wheel hub, thus achieving radial fixation of the wheel hub. The second electric telescopic rod 915 is then controlled to extend... As the first pressure plate 916 moves upward, the third electric telescopic rod 917 extends, pushing the two second pressure plates 918 outward. Then, the second electric telescopic rod 915 retracts, and the first pressure plate 916 moves downward until the bottom surface of the second pressure plate 918 is in contact with the center area of ​​the top surface of the hub. After applying a preset pressure, it stops and is in contact with the edge area of ​​the top surface of the hub, ensuring that the hub is not loose in the axial direction. Even if it rotates or wobbles later, it can remain stable to prevent radial movement during drying and prevent the initial placement of the hub from being offset.

[0043] Cylinder 13 pushes the lifting plate 3 upward along the guide column of the guide mechanism 8. The support column drives the sensor mounting plate 12 to rise synchronously. The rotating table 4 moves upward with the sensor mounting rod 41 and the connecting part 42 until the hub on the top plate 10 reaches the effective drying height of the drying equipment. Cylinder 13 stops extending and retracting, completing the height adjustment. The guide mechanism 8 ensures that the lifting plate 3 moves smoothly throughout the process and avoids tilting. The first motor 2 is started. Its output end is reduced by the planetary reducer and drives the connecting part 42 to rotate through the coupling 7. The connecting part 42 drives the sensor mounting rod 41 and the rotating table 4 to rotate synchronously. During the rotation, the first sensor 6 rotates with the sensor mounting rod 41. When a first sensor 6 is aligned with the first sensor 5 on the sensor mounting plate 12, the first sensor 5 sends a signal to the control system. The system judges whether the rotation angle meets the preset drying angle. If it does not meet the standard, it continues to control the first motor 2 to rotate until the rotating table 4 stops precisely at the target angle. The first motor 2 stops, completing the rotation positioning, thereby achieving accurate position detection.

[0044] The second motor 93 is started, and its output drives the swing bracket 94 to rotate. The swing bracket 94 drives the U-shaped bracket 96 to move flexibly via the universal ball joint 95. The U-shaped bracket 96 is fixedly connected to the rotating drum 97. The rotating drum 97 drives the fixed plate 99 and the swing rod 902 to reciprocate around the rotation axis of the support plate 901 via the connecting rod 98. When the swing rod 902 swings, the rocker arms 907 at both ends move accordingly, driving the piston 909 to reciprocate linearly within the air chamber 908. When the piston 909 moves upward, the air pressure inside the air chamber 908 decreases, the first one-way valve 9091 opens, and external air is drawn into the air chamber 908. When the piston 909 moves downward, the air pressure inside the air chamber 908 increases, the first one-way valve 9091 closes, and the second... One-way valve 9092 opens, and compressed air is delivered to air collection cylinder 904 through two air transmission pipes 9093. After the air collection cylinder 904 stabilizes the air pressure, it is delivered to air outlet cylinder 905. Finally, multiple jet nozzles 906 on the outside of air outlet cylinder 905 spray air evenly onto the surface of the wheel hub. In conjunction with the external drying heat source, the evaporation of moisture on the surface of the wheel hub is accelerated. The oscillating motion ensures that there are no dead angles in the jetting, resulting in more uniform drying. During the drying process, the first motor 2 starts intermittently, driving the rotary table 4 to rotate slowly, so that the wheel hub is heated evenly in the circumferential direction. At the same time, the second motor 93 continuously drives the steering mechanism 9, so that the wheel hub keeps oscillating back and forth. The jet nozzles 906 spray air synchronously with the oscillation, realizing three-dimensional dynamic drying, which greatly improves the drying efficiency and drying quality, and avoids incomplete drying of some parts of the wheel hub.

[0045] When the drying time reaches the preset value, or the external detection equipment detects that the wheel hub is dry enough, the control system first shuts down the second motor 93, the steering mechanism 9 stops swaying, and the wheel hub returns to a horizontal state. Then, the first motor 2 is shut down, the rotary table 4 stops rotating, the lifting plate 3 moves downward along the guide mechanism 8 and returns to the initial position. The control system controls the first electric telescopic rod 913 to retract, the clamping plate 914 moves towards the center of the positioning block 912 to release the radial clamping of the wheel hub, the second electric telescopic rod 915 extends, the first pressure plate 916 rises, the third electric telescopic rod 917 retracts, the second pressure plate 918 resets, and the axial clamping of the wheel hub is completely released. The external robotic arm lifts the dried wheel hub and moves it away from the clamping mechanism 910, completing the wheel hub removal and placement.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
