Technical Field

[0001] This utility model relates to the field of wheel hub assembly technology, specifically to an auxiliary positioning device for wheel hub assembly. Background Technology

[0002] In assembly scenarios, dynamic balancing is an indispensable and standardized quality inspection and calibration process on the wheel assembly line. It is a key step in ensuring the quality of the entire vehicle before it leaves the factory, so it is absolutely an integral part of the assembly process. During dynamic balancing, a positioning tool is used to clamp and position the wheel hub and rotate it, so that the dynamic balancing testing device can directly test the dynamic balance of the wheel hub.

[0003] However, most existing positioning devices use a structure that expands the center of the wheel hub to rotate the hub mechanism. The expanded cone is easily affected by the surrounding environment or dirt on the wheel hub surface, and can become contaminated with foreign objects. The mounting back of the wheel hub (the surface that contacts the balancing machine clamp) and the center hole can become contaminated with mud, rust, brake dust, or residue from old balance weights. These tiny particles can cause the wheel hub to be out of center or not to fit properly on the machine, resulting in huge measurement errors. Therefore, accurately and concentrically fixing the wheel hub on the balancing machine is the foundation of everything. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary positioning device for wheel hub assembly, which makes the device more stable when limiting the wheel hub and driving its rotation, thereby ensuring the accuracy of subsequent dynamic balance testing.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 As shown, an auxiliary positioning device for wheel hub assembly includes a mounting frame 1. The mounting frame 1 can be fixed to the worktable through the set holes, so that the device is more stable during use. Positioning components 2 are installed at two places on the top of the mounting frame 1. The positioning components 2 are composed of a servo motor, a clamping arm and a positioning wheel. Under this action, the wheel hub can be clamped and positioned by the cooperation of the positioning components 2, so that it will not easily have a large positional deviation during inspection.

[0016] The inner cavity of the mounting bracket 1 is equipped with an electric telescopic rod 3. The output shaft of the electric telescopic rod 3 is equipped with a power assembly 4. The power assembly 4 consists of a motor and a spreading component. Under this action, the position of the power assembly 4 can be adjusted by the cooperation of the electric telescopic rod 3. Furthermore, the power assembly 4 can be locked inside the wheel hub by the action of its own structure. Subsequently, under the action of the motor, the wheel hub is positioned and rotated to detect the dynamic balance of the wheel hub, thereby ensuring the performance of the wheel hub during assembly.

[0017] The inner wall of the mounting bracket 1 is provided with a fixing groove 5. A cleaning mechanism 6 is installed in the inner cavity of the fixing groove 5. The cleaning mechanism 6 can clean the surface of the power component 4 when the electric telescopic rod 3 drives the power component 4 to move, thereby reducing the foreign matter on its surface and effectively improving the cleanliness of the power component 4. This prevents the surface from affecting the opening effect of the wheel hub under the action of foreign matter, effectively improving the connection effect between the device and the wheel hub, so that the device can more accurately detect the dynamic balance of the wheel hub.

[0018] The mounting bracket 1 has a connecting groove 7 in its inner cavity. A fixed shell 8 is fixedly connected to the inner cavity of the connecting groove 7. A piston plate 10 is slidably connected to the inner cavity of the fixed shell 8. A fixed rod 9 is fixedly connected to the bottom of the piston plate 10. A blowing assembly 11 is provided on the surface of the fixed shell 8. Under this action, the piston plate 10 and the fixed shell 8 can cooperate with each other when the power assembly 4 moves through the cooperation of the fixed rod 9 and the piston plate 10, so that air can be cleaned on the surface of the cleaning mechanism 6 and the power assembly 4 through the blowing assembly 11, further improving the cleanliness of the power assembly 4.

[0019] The cleaning mechanism 6 can clean stubborn stains on the surface of the power component 4, and the surface of the cleaning mechanism 6 can be cleaned by the blowing component 11. It can also clean loose stains on the surface of the power component 4, ensuring the cleanliness of the power component 4 during repeated use and effectively improving the accuracy of the device's detection.

[0020] The cleaning mechanism 6 includes a connecting frame 61 fixed to the output shaft of the electric telescopic rod 3. A rack plate 62 is fixedly connected to the surface of the connecting frame 61. A spur gear 63 meshes with one side of the rack plate 62. A connecting component 64 is provided on one side of the spur gear 63. In this embodiment, the cooperation between the connecting frame 61 and the rack plate 62 allows the electric telescopic rod 3 to move by driving the rack plate 62 through the connecting frame 61, thereby driving the spur gear 63 to rotate. This provides power for the cleaning of the connecting component 64 and ensures the power required for cleaning the power component 4.

[0021] The surfaces of the connecting frame 61 and the rack plate 62 are slidably connected to the inner wall of the fixing groove 5, and one side of the spur gear 63 is rotatably connected to the inner wall of the fixing groove 5. Under this action, the connecting frame 61 and the rack plate 62 can be more stable when moving through the inner wall of the fixing groove 5, avoiding large positional displacement during movement that would affect the meshing effect between the rack plate 62 and the spur gear 63.

[0022] The fixing rod 9 has a U-shaped structure design, and the surface of the fixing rod 9 is slidably connected to the inner wall of the fixing shell 8 through a sealing gasket. One side of the connecting frame 61 is fixedly connected to the surface of the fixing rod 9. Under this action, the fixing rod 9 can move when the connecting frame 61 moves due to the shape. With the cooperation of the sealing gasket, the piston plate 10 can ensure the compression effect on the air when it moves back and forth, and prevent the air inside the fixing shell 8 from overflowing at will and affecting the use effect of the blowing component 11.

[0023] The connecting component 64 includes a bevel gear 641 fixed to one side of the spur gear 63. A bevel gear ring 642 meshes with the surface of the bevel gear 641. A cleaning ring 643 is fixedly connected to the inner wall of the bevel gear ring 642. The cleaning ring 643 works in conjunction with the power component 4. In this embodiment, the cooperation between the bevel gear 641 and the bevel gear ring 642 allows the spur gear 63 to rotate, thereby driving the cleaning ring 643 to rotate. This enables the power component 4 to clean its surface when it moves up and down, thus removing stubborn foreign matter from the surface of the power component 4 and reducing the possibility of excessive foreign matter being squeezed, deformed, and adhering to the surface of the power component 4, which could affect the accuracy of subsequent detection.

[0024] The cleaning part inside the cleaning ring 643 is designed to be flexible. Under this function, it can clean the power component 4 above the air without damaging its surface. It can also adapt to the shape of the power component 4 by deformation, thereby improving the cleaning effect on the power component 4.

[0025] The surfaces of the cleaning ring 643 and the bevel ring 642 are slidably connected to the inner wall of the fixing groove 5. Under this action, the bevel ring 642 and the cleaning ring 643 can be limited by the inner wall of the fixing groove 5, so that they can be more stable when rotating.

[0026] The blowing assembly 11 includes a first one-way valve 112 connected to the upper and lower parts of the surface of the fixed housing 8. A connecting pipe 111 is connected to one side of the first one-way valve 112, and two first one-way valves 112 can be connected through the cooperation of the connecting pipe 111. A second one-way valve 113 is connected to both the upper and lower parts of one side of the surface of the fixed housing 8. An air distribution pipe 114 is connected to the surface of the connecting pipe 111, and the surface of the air distribution pipe 114 is fixedly connected to the inner wall of the mounting bracket 1. In this embodiment, under this action, when the fixed rod 9 drives the piston plate 10 to move upward inside the fixed housing 8, the first one-way valve 112 near the upper part of the connecting pipe 111 is in the open state, and air will enter the interior of the connecting pipe 111, thereby facilitating the air distribution pipe. Air is discharged from the 114th valve, while the second one-way valve 113 on the lower side is open, allowing air from the connecting groove 7 to enter the interior of the fixed housing 8 for the next air discharge. When the piston plate 10 moves downward into the interior of the fixed housing 8, the first one-way valve 112 above the surface of the connecting pipe 111 is closed, while the first one-way valve 112 below is open, discharging air from the interior of the fixed housing 8. Meanwhile, the second one-way valve 113 above is open, drawing air into the interior of the fixed housing 8. This reciprocating design ensures that the power assembly 4 is cleaned by air each time it rises or falls, thus guaranteeing a cleanliness of the power assembly 4.

[0027] The inner cavity of the air distribution pipe 114 is designed with several air outlets, and each air outlet is designed to be inclined downward. This combination allows the air distribution pipe 114 to discharge air, thereby cleaning the power component 4 and the cleaning ring 643 to the greatest extent. In addition, the inclined combination can also blow foreign objects away from the interior of the mounting frame 1, ensuring the cleanliness of the interior of the mounting frame 1.

[0028] It is worth noting that the technical features proposed in this technical solution, such as the mounting bracket 1, positioning component 2, electric telescopic rod 3, and power component 4, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0029] Working principle: First, the wheel hub to be fixed is placed on top of the mounting bracket 1. Then, the positioning component 2 can simultaneously press four points of the wheel hub to center the wheel hub in the mounting bracket 1. Then, the electric telescopic rod 3 drives the power component 4 to move and lock it inside the wheel hub. Next, the positioning component 2 releases the wheel hub from its position, the dynamic balance detection component is connected to the wheel hub, and then the power component 4 is turned on to rotate the wheel hub for detection.

[0030] After the test is completed, the power component 4 is turned off and returned to its original position by the electric telescopic rod 3. When the power component 4 moves, the connecting frame 61 moves the rack plate 62 through the electric telescopic rod 3. The rack plate 62, through the cooperation of the spur gear 63 and the bevel gear 641, causes the bevel gear ring 642 to drive the cleaning ring 643 to rotate, thereby rubbing and cleaning the surface of the power component 4, reducing foreign matter on its surface and effectively improving the cleanliness of the power component 4.

[0031] Furthermore, when the connecting frame 61 moves, it can also drive the piston plate 10 to move inside the fixed housing 8 through the cooperation of the fixed rod 9. Under the action of the piston plate 10, air can be discharged from the air distribution pipe 114 through the connecting pipe 111 after the cooperation of the first one-way valve 112 below, thereby cleaning the inside of the cleaning ring 643 and the surface of the power component 4. Under the cooperation of the second one-way valve 113 above, air will enter the upper part of the inner cavity of the fixed housing 8 to prepare for the next cleaning.

[0032] When another wheel hub needs to be positioned, the surface of the power assembly 4 is cleaned by the cleaning mechanism 6 when the power assembly 4 is raised by the electric telescopic rod 3. In addition, with the cooperation of the first one-way valve 112 and the second one-way valve 113, the air distribution pipe 114 can still discharge air to clean the power assembly 4 and the cleaning ring 643, thereby further ensuring the cleanliness of the power assembly 4 and the cleaning ring 643 and improving the stability of the device when fixing and limiting the wheel hub.
