The bottom end of the wire rack 3 is fixed to the support platform 1. The wire rack 3 is equipped with an adjustment panel 4 that can move along its length direction. The adjustment panel 4 is equipped with a shift component 5. The steering wheel is moved for cleaning and removed after completion through the shift component 5. The shift component 5 is driven by the control component 6 to realize position movement. Placement tables 7 are arranged on both sides of the ultrasonic cleaning machine 2, and the steering wheel before and after cleaning can be placed on the placement tables 7.

[0044] For further information, please refer to Figure 2 and Figure 4The wire rack 3 includes a top frame 31 and a bracket 32 ​​whose top end is fixed to the top frame 31 .

[0045] Among them, the adjustment panel 4 includes a panel 41, a guide rail 42 fixed to the bottom surface of the panel 41, and a travel component 44 installed on the outside of the panel 41. The outer side of the guide rail 42 is slidably connected to the top frame 31, and the guide rail 42 can only slide along the length direction of the top frame 31, thereby driving the panel 41 to move left and right.

[0046] Specifically, a rack 33 is fixedly arranged on the inner side of the top frame 31, and the travel assembly 44 includes a mounting groove 441 opened on the outer side of the panel 41, a first gear 442 arranged in the mounting groove 441, a synchronization shaft 443 coaxially fixed with the first gear 442, a side plate 444 fixedly connected to the panel 41 at the bottom end, and a first motor 445, the outer side of the first gear 442 is meshed with the rack 33, both ends of the synchronization shaft 443 are rotatably mounted on the side plate 444, and the output shaft of the first motor 445 is inserted into the side plate 444 and is fixed to the synchronization shaft 443;

[0047] The first motor 445 drives the synchronization shaft 443 to rotate, so that the first gear 442 can apply force to the panel 41 through the rack 33 after keeping rotating, so that the panel 41 can move in the left and right direction along the rack 33.

[0048] For further information, please refer to Figure 2 and Figure 3 A slide groove 43 is provided on the panel 41, and the shifting components 5 are arranged inside the slide groove 43 in a bilaterally symmetrical manner, so that the shifting components 5 in each slide groove 43 are a group, and each group of shifting components 5 cooperates with each other to support and shift the direction plate.

[0049] Specifically, the shifting assembly 5 includes a vertical plate 51 whose outer wall is in sliding contact with the slide groove 43, a synchronization frame 52 fixed to the vertical plate 51 near the midpoint of the slide groove 43, and a contact frame 53 whose top end is bolted to the vertical plate 51. The contact frame 53 is L-shaped as a whole, and after its bottom end extends into the inner side of the steering wheel, the bottom horizontal part of the contact frame 53 can be inserted and fitted with the lower edge of the steering wheel through movement, thereby lifting and moving the steering wheel;

[0050] At the same time, the contact frame 53 is used to drag the steering wheel to move and immerse it in the ultrasonic water pool. When the steering wheel is cleaned, the contact frame 53 will also be affected by the wear caused by the ultrasonic cavitation phenomenon. Therefore, the contact frame 53 is installed with the vertical plate 51 by bolts, and can be quickly replaced after wear, thereby increasing the service life of the equipment.

[0051] For further information, please refer to Figure 3The control assembly 6 includes a driving strip 61 whose bottom surface is in sliding contact with the panel 41, a lifting control member 62 installed on the driving strip 61, and a telescopic control member 63 that rotates with the outer side of the driving strip 61. In each group of shifting assemblies 5, the driving strip 61 is arranged at two locations in a left-right interval manner, and is respectively connected to the synchronization frame 52 symmetrically arranged on the left and right.

[0052] For details, please refer to Figure 7 The outer wall of the driving strip 61 is plugged into the synchronization frame 52, the outer side of the driving strip 61 is vertically fixed to the sliding rod 611, a fixed plate 612 is fixedly installed on the surface of the panel 41, the outer wall of the sliding rod 611 is slidably matched with the fixed plate 612, and a spring 613 is fixed between the driving strip 61 and the fixed plate 612, so that when the adjacent driving strips 61 are forced to move away from each other, they can be reset by the elastic force of the spring 613.

[0053] Please refer to Figure 5 The inner wall of the synchronization frame 52 is provided with tooth grooves 521 arranged in an array along its height direction. The lifting control member 62 includes a second gear 621 meshing with the tooth grooves 521 on the outer side, a worm wheel 622 coaxially fixed with the second gear 621, a worm 623 meshing with the outer side of the worm wheel 622, and a driving assembly connected to the worm 623. The second gear 621 and the worm wheel 622 are both rotatably mounted on the driving strip 61. The worm 623 is driven to rotate by the driving assembly, and after the worm wheel 622 rotates, the second gear 621 can be driven to rotate, so that the inner wall of the synchronization frame 52 is subjected to force through the tooth grooves 521, thereby driving the vertical plate 51 to move upward or downward in the slide groove 43 along the driving strip 61, so that the bottom end of the contact frame 53 can complete the up and down movement.

[0054] When implementing, please refer to Figure 6 The driving strip plate 61 has a hollow structure inside, and the driving assembly includes a driving rod 624 rotatably connected to the driving strip plate 61 on the outside, a first bevel tooth 625 coaxially fixed to the bottom end of the driving rod 624, a second bevel tooth 626 meshing with the first bevel tooth 625 on the outside, and a second motor 627 coaxially fixed to the conveying shaft and the second bevel tooth 626. The top end of the driving rod 624 is fixed to the worm 623, and the second motor 627 is fixed inside the driving strip plate 61;

[0055] The second bevel gear 626 is driven to rotate by the second motor 627, and the first bevel gear 625 is able to drive the driving rod 624 to rotate after being subjected to force, so that the worm 623 keeps rotating, and the second gear 621 can respond quickly to the rotation.

[0056] For details, please refer to Figure 2 and Figure 3The placement table 7 includes a plate body 71, a bottom frame 72 whose top is fixed to the plate body 71, and a placement groove 73 opened on the plate body 71. The bottom end of the bottom frame 72 is fixed to the support platform 1, and the placement groove 73 is used to place the protruding bottom surface part of the steering wheel, so that after the steering wheel is placed in the placement groove 73, the bottom end of the contact frame 53 can first move downward to the inner side of the circular circumference of the steering wheel, and then expand and move left and right to plug into the bottom surface of the steering wheel circular edge and lift it up, so as to facilitate the quick placement of the steering wheel to be cleaned in the placement groove 73 for placement and waiting for cleaning, or take the cleaned steering wheel out to another placement table 7, waiting to be moved to the next process, thereby improving the convenience and orderliness of the operation.

[0057] Furthermore, the telescopic control member 63 includes a thrust assembly and a telescopic assembly. The telescopic assembly is connected to the driving strip 61. The thrust assembly provides driving force for the telescopic assembly, so that two adjacent driving strips 61 can move away from or closer to each other, thereby expanding or contracting the contact frame 53 to facilitate moving the steering wheel and separating it.

[0058] For details, please refer to Figure 7 and Figure 8 The thrust assembly includes a push cylinder 81 fixed to the upper surface of the panel 41, a push frame 82 with one end fixedly connected to the output end of the push cylinder 81, a support 83 in sliding contact with the outer side of the push frame 82, and a push hook 84 fixed to the outer side of the push frame 82. The bottom end of the support 83 remains fixed to the panel 41, and the push frame 82 moves linearly along the support 83 to drive the push hook 84 to move linearly or retract.

[0059] Among them, the telescopic assembly includes a mounting frame 91 whose bottom end is fixedly connected to the upper surface of the panel 41 and a first push rod 92, a second push rod 93, a third push rod 94 and a third push rod 95 which are rotatably arranged on the mounting frame 91 at the top. The bottom ends of the first push rod 92, the second push rod 93, the third push rod 94 and the fourth push rod 95 are rotatably connected to the driving strip 61. The first push rod 92 and the second push rod 93 are a group, and the third push rod 94 and the fourth push rod 95 are a group. Each group is respectively connected to a driving strip 61 adjacent to the left and right.

[0060] During implementation, a groove 614 is provided on the surface of the driving strip 61. The protruding rotating column structures at the bottom ends of the first push rod 92, the second push rod 93, the third push rod 94 and the fourth push rod 95 can rotate in the groove 614 or slide along the groove 614. The second push rod 93 and the third push rod 94 are integrally fixed with a disk 96 at one end adjacent to the mounting frame 91, and a latch tooth 97 is fixed on the outer side of the disk 96. The second push rod 93 and the third push rod 94 are meshed with each other through the latch tooth 97, so that when the second push rod 93 rotates toward the midpoint of the slide groove 43, an outward rotational force is applied to the third push rod 94 through the latch tooth 97, so that the two use the connection point with the mounting frame 91 as the rotation fulcrum, and then apply an outward thrust to the two adjacent driving strips 61, so that the driving strips 61 drive the vertical plates 51 to move away from each other, thereby making the contact frames 53 move away from each other.

[0061] Among them, a force-bearing frame 98 is integrally fixed to one end of the first push rod 92 close to the mounting frame 91, and the force-bearing frame 98 forms a mounting angle greater than 90° with the mounting frame 91. The upper surface of the force-bearing frame 98 is fixed to the boss 99, and the outer side of the boss 99 is in contact with the push hook 84. When the push hook 84 is pushed outward under the action of the push cylinder 81, a thrust is applied to the boss 99, so that the boss 99 causes the first push rod 92 to rotate counterclockwise with the connection point on the mounting frame 91 as the rotation fulcrum, so that after the driving strip 61 connected to the first push rod 92 is forced to move outward, one end of the second push rod 93 is driven to move outward, so that the second push rod 93 drives the third push rod 94 to move through the latch tooth 97, thereby realizing the mutual distance between the two driving strips 61, and when the push hook 84 is reset, the driving strip 61 is reset by the spring 613.

[0062] By adopting the above-mentioned technical scheme, the position of each group of shifting components 5 is matched with the position of the placement slot 73 up and down. When each group of shifting components 5 moves to the placement slot 73 after passing through the moving panel 41, the contact frame 53 can be moved down, and then moved outward to be plugged and fitted with the lower edge of the steering wheel, and then the contact frame 53 is moved up a distance, so that the panel 4 drives the steering wheel to move above the ultrasonic cleaning machine 2, and then moves down for cleaning. After completion, it moves up and continues to move to the right, and is placed in the placement slot 73 after cleaning, and then the contact frame 53 continues to operate, and so on.

[0063] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and wiring layout in detail.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
