[0002] In the manufacturing process of motorcycle wheels, if sand core casting technology is used, sand core cleaning is a very important step. After the sand core casting is completed, the sand core needs to be thoroughly removed from the casting to ensure the surface quality and mechanical properties of the wheel.

[0003] At present, most of the existing cleaning methods rely on manual operation. The operator needs to manually put the wheel hub into the cleaning tank or use a high-pressure water gun to clean it one by one. Manually cleaning each wheel hub takes a long time and requires repeated operations. In addition, each operator has different skill levels and experiences, resulting in uneven cleaning efficiency. The cleaning work requires the operator to stand for a long time and perform repetitive labor. The labor intensity is high and it is easy to cause operator fatigue, which in turn affects the cleaning quality. In addition, during the manual cleaning process, the cleaning quality is greatly affected by the operator's subjective factors, and it is difficult to ensure the consistency of the cleaning quality of each batch of wheel hubs.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0027] Embodiment 1: The embodiment of the present invention provides a motorcycle aluminum alloy wheel sand core cleaning device, such as Figure 1 As shown, it includes a cleaning frame 1, and first electric slide rails 2 are installed on the left and right sides of the cleaning frame 1, and second electric slide rails 3 are installed between the sliders of the first electric slide rails 2 on both sides, and the slider of the second electric slide rail 3 is rotatably connected with a rotating rod 4, and the rotating rod 4 is connected with a nozzle 5, and the nozzle of the nozzle 5 is composed of a plurality of evenly distributed small holes. The lower side of the nozzle 5 is a liquid containing chamber, and the liquid containing chamber is connected to an external water pipe. The direction in which the first electric slide rail 2 drives the second electric slide rail 3 to move is perpendicular to the direction in which the second electric slide rail 3 drives the nozzle 5 to move.

[0028] When the sand core of the motorcycle aluminum alloy wheel hub needs to be cleaned, the motorcycle wheel hub is placed in the cleaning frame 1, and then the first electric slide rail 2 and the second electric slide rail 3 are started. The first electric slide rail 2 drives the second electric slide rail 3 to move forward and backward, and the second electric slide rail 3 drives the nozzle 5 to move left and right, so that the nozzle can fully clean the motorcycle wheel hub without manual operation, saving manpower.

[0029] Embodiment 2: Based on embodiment 1, Figure 2-Figure 7 As shown, a telescopic rod 6 is slidably connected to the nozzle 5, and a switching head 7 is connected to the side of the telescopic rod 6 close to the nozzle 5. A small hole is opened in the middle of the switching head 7 to match the nozzle in the middle of the nozzle 5. A plurality of round rods that match the small holes of the nozzle 5 are arranged on the switching head 7. The round rods are used to block the nozzle of the nozzle 5 so that only one nozzle in the middle of the nozzle 5 remains unobstructed. A cylinder 8 is installed in the middle of the second electric slide rail 3, and a rack 9 is connected to the telescopic end of the cylinder 8. A gear 10 is connected to the middle of the rotating rod 4, and the rack 9 is meshed with the gear 10. The bottom of the rack 9 is rotatably connected to a swing rod 11. The telescopic rod 6 is composed of an inner rod, an outer rod and an elastic member. The outer rod is slidably connected to the nozzle 5, and the inner rod slides in the outer rod, and the inner rod is rotatably connected to the swing rod 11.

[0030] Furthermore, wedge blocks 12 for locking the switching head 7 are slidably connected on both sides of the nozzle 5, and a first spring 13 is connected between the wedge block 12 and the nozzle 5; the nozzle 5 is continuously and rotatably connected to a lever 14, and a torsion spring 15 is connected between the lever 14 and the nozzle 5; the nozzle 5 is slidably connected to a push column 16, and the push column 16 is used to push the lever 14 to rotate, and the lever 14 is squeezed and matched with the wedge block 12.

[0031] When the motorcycle wheel hub is completely rinsed by the vertical nozzle 5, the operator can start the cylinder 8, so that the telescopic end of the cylinder 8 drives the rack 9 to move downward, thereby driving the gear 10 to rotate, so that the gear 10 drives the rotating rod 4 and the nozzle 5 to rotate to the inclined state. The rack 9 moves downward and drives the swing rod 11 to swing, thereby driving the telescopic rod 6 to move downward, so that the telescopic rod 6 drives the switching head 7 to move downward to fit with the nozzle 5, so that only one nozzle in the middle of the nozzle 5 remains unobstructed, achieving the purpose of changing the spray angle of the nozzle 5 while switching the state of the nozzle 5, and the downward movement of the switching head 7 will squeeze the wedge block 12 to move outward, so that the first spring 13 is reset, and the wedge block 12 squeezes the lever 14 to rotate, so that the torsion spring 15 is deformed. When the switching head 7 passes over the wedge block 12 and fits with the nozzle 5, the torsion spring 15 is reset and drives the lever 14 to rotate and reset, so that the wedge block 12 moves inward to block the switching head 7, and the first spring 13 is After washing the motorcycle wheel hub at one angle, the operator can start the cylinder 8, so that the telescopic end of the cylinder 8 drives the rack 9 to move upward, so that the spray head 5 is reset first and then rotated in the opposite direction, and the upward movement of the rack 9 will drive the swing rod 11 to move upward. Since the switching head 7 is stuck by the wedge block 12, the switching head 7 cannot move upward, and the inner rod of the telescopic rod 6 moves upward with the swing rod 11, and the elastic member in the telescopic rod 6 is stretched until the spray head 5 rotates to another angle, and the motorcycle wheel hub is washed again at a new angle. If it is necessary to switch the spray head 5 again, it is only necessary to squeeze the push column 16 inwardly, so that the push column 16 moves inwardly, drives the lever 14 to rotate, and the torsion spring 15 is deformed, and the lever 14 no longer squeezes the wedge block 12, so that the first spring 13 is reset and drives the wedge block 12 to reset. Under the reset action of the elastic member of the telescopic rod 6, the switching head 7 moves upward and resets, and then the operator releases the push column 16.

[0032] Embodiment 3: Based on embodiment 2, Figure 8 and Fig. 9 As shown, a rotating seat 17 is connected to the bottom of the cleaning frame 1. The rotating seat 17 is externally connected to a power source, and the rotation angle each time is controlled by a program, in coordination with the control program of the first electric slide rail 2 and the second electric slide rail 3, to clean the motorcycle wheel hub. The rotating seat 17 is used to support the wheel hub.

[0033] A support block 18 is slidably connected to the rotating seat 17, a second spring 19 is connected between the support block 18 and the rotating seat 17, a locking block 20 is slidably connected to the rotating seat 17, an elastic member is connected between the locking block 20 and the rotating seat 17, the locking block 20 is used to clamp the upper side of the wheel hub, the support block 18 is used to support the lower side of the wheel hub, and a ball 21 is slidably connected to the rotating seat 17, the ball 21 is distributed in an area close to the support block 18, and the ball 21 is squeezed and fitted with the support block 18.

[0034] The motorcycle wheel hub is inserted into the support block 18. The support block 18 cooperates with the second spring 19 to adapt to motorcycle wheel hubs of different thicknesses. During the high-pressure washing of the nozzle 5, the support block 18 will continuously move up and down under the influence of gravity and the impact force of water, and cooperate with the ball 21 to achieve the vibration of the motorcycle wheel hub. That is, the motorcycle wheel hub is continuously vibrated during the cleaning process to shake off the cleaned impurities and ensure the cleaning effect.

[0035] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
