[0003] A wheel is a rigid wheel that fixes the inner edge of the tire, supports the tire, and shares the load with the tire. The tire, wheel, and spokes that are combined together are collectively called a wheel. The wheel assembly consists of two main components: the wheel and the tire. As the total production of automobiles continues to rise and the number of people driving cars gradually expands, the safety of passengers and drivers is of great concern when vehicles are traveling at high speeds. Tires are an essential part of the structure of automobiles.
[0004] During the tire manufacturing process, drilling equipment is required for processing, which necessitates improving the overall safety and protection of the tires.
[0005] The existing technology has the following problems:
[0006] In actual use, the existing device is not convenient for tightly clamping wheels of different sizes, and cannot prevent the wheels from shaking during processing, which can easily affect the processing. At the same time, a large amount of debris is generated during processing, which can easily cause injury to personnel, making the device's safety protection effect not high. Utility Model Content
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This utility model provides a safety protection device for processing tubeless lightweight steel wheels. Through a fixing mechanism, an electric push rod can push the connecting seat to move, so that the connecting seat can drive the clamping plates on both sides to move synchronously. The clamping plates drive the connecting frames on both sides to move closer to each other on the slide rod, thereby bringing the steel wheel closer and clamping it, making it less likely to loosen during steel wheel processing. The distance between the clamping plates can be adjusted, which is convenient for fixing steel wheels of different sizes and greatly improves flexibility.
[0019] This utility model provides a safety protection device for processing tubeless lightweight steel wheels. After the steel wheel is fixed by the protective mechanism, the rotating screw can drive the threaded seat and the frame to move downward, thereby pushing the protective cover downward so that the bottom of the protective cover can fit against the upper end of the machine. Then, the hydraulic cylinder can push the mounting cover downward so that the processing drill can process the steel wheel. The external protective cover can block the debris generated during processing, preventing the debris from flying onto the personnel, thereby improving the safety protection effect of the device.

[0026] The present invention will be further described in detail below with reference to embodiments:
[0027] like Figures 1-5As shown, this utility model provides a safety protection device for processing tubeless lightweight steel wheels, including a machine base 1. Several through holes 2 are opened through the middle of the upper end of the machine base 1. A fixing mechanism 3 is provided at the upper end of the machine base 1, and a protective mechanism 4 is provided above the fixing mechanism 3. A mounting seat 5 is fixedly provided at the rear end of the machine base 1. A partition 6 is fixedly provided on the inner side of the lower end of the machine base 1. A frame 7 is fixedly provided at the upper end of the partition 6. A collection frame 8 is movably installed inside the frame 7. An end plate 9 is fixedly connected to the front end of the collection frame 8.
[0028] The through hole 2 is connected to the interior of the collection frame 8.
[0029] In this solution, debris on the machine 1 can fall into the collection box 8 inside the frame 7 through the through hole 2. The through hole ensures that the debris is collected so that the machine 1 is kept clean. By pulling the end plate 9 outward, the collection box 8 can be easily pulled out of the frame 7 for easy cleaning.
[0030] like Figure 4 As shown, the fixing mechanism 3 includes a horizontal plate 31. The lower end of the horizontal plate 31 is symmetrically fixedly connected to both sides of the upper end of the machine base 1. Slide rods 32 are fixedly provided at both ends of the inner side of the horizontal plate 31. Connecting frames 33 are slidably connected to both sides of the outer side of the slide rods 32. Clamping plates 34 are fixedly provided on the inner side of the connecting frames 33. Connecting seats 35 are fixedly installed at the lower middle part of the clamping plates 34. Electric push rods 36 are fixedly provided in the middle of the horizontal plate 31.
[0031] The opposite surfaces of the clamping plate 34 are arc-shaped, and a rubber pad is glued to the inner side of the clamping plate 34.
[0032] The top of the output rod of the electric actuator 36 is fixedly installed on one side of the connecting seat 35.
[0033] In this solution, the connecting seat 35 is moved to different distances by the electric push rod 36, which in turn moves the connecting frame 33 and the clamping plate 34 to the appropriate position, so as to realize the flexible adjustment of the distance between the clamping plates 34. This can meet the needs of fixing wheels of different sizes, greatly improving the flexibility and versatility of the device in practical applications.
[0034] like Figure 5 As shown, the protective mechanism 4 includes a frame 41, the lower end of which is fixedly connected to the upper end of the mounting base 5. A lead screw 42 is rotatably mounted on the inner side of the frame 41. A threaded seat 43 is threadedly connected to the outer side of the lead screw 42. A frame 44 is fixedly connected to the front end of the threaded seat 43. A motor 45 is fixedly mounted on the top of the frame 41. Guide grooves 46 are opened through both sides of the frame 41. Guide blocks 47 are fixedly mounted on both sides of the threaded seat 43.
[0035] A protective cover 48 is fixedly installed at the lower end of the frame 44. A hydraulic cylinder 49 is fixedly installed at the middle of the upper end of the protective cover 48. A mounting cover 410 is fixedly installed at the lower end of the output rod of the hydraulic cylinder 49. A second motor 411 is fixedly installed inside the mounting cover 410. A processing drill bit 412 is driven and installed at the lower end of the output end of the second motor 411.
[0036] The top end of the lead screw 42 is driven and installed at the output end of the motor 45. The guide block 47 matches the guide groove 46 and is slidably connected.
[0037] The lower end of the protective cover 48 is externally and movably installed on the upper end of the machine base 1.
[0038] In this design, when the threaded seat 43 is moved up and down by the rotating lead screw 42, the threaded seat 43 can drive the guide block 47 to slide synchronously in the guide groove 46, so as to limit the threaded seat 43 and improve its smoothness of movement.
[0039] The working principle of this safety protection device for processing tubeless lightweight steel wheels will be explained in detail below.
[0040] like Figures 1-5As shown, the safety protection device for processing tubeless lightweight steel wheels allows the steel wheel to be processed to be placed in the middle of the machine base 1 during use. When it is necessary to fix the steel wheel, the electric push rod 36 can be activated. The electric push rod 36 can push the connecting seat 35 to move, and the connecting seat 35 can drive the clamping plate 34 to move synchronously. The movement of the clamping plate 34 will drive the connecting brackets 33 at both ends to move synchronously on the slide rod 32. As the clamping plate 34 gradually approaches, the rubber pad on the arc-shaped clamping plate 34 gradually contacts the edge of the steel wheel. When the clamping plate 34 is fully in contact with the wheel surface, the electric push rod 36 can be pushed again, and the pressure applied to the wheel by the clamping plate 34 will gradually increase until the set clamping force is reached, thereby firmly fixing the steel wheel and ensuring that the steel wheel is not easy to loosen, thus ensuring the processing accuracy and quality. During processing, the motor 45 can be activated. 45 drives the lead screw 42 to rotate. Under the rotation of the lead screw 42, the threaded seat 43 can move downward. At the same time, the threaded seat 43 drives the frame 44 to move downward together. The downward movement of the frame 44 pushes the protective cover 48 connected to it to move downward synchronously. As the protective cover 48 gradually descends, its bottom can finally fit precisely and tightly with the upper end of the machine base 1. Then, the hydraulic cylinder 49 can be activated. The hydraulic cylinder 49 can push the mounting cover 410 downward. However, when the mounting cover 410 is in place, the second motor 411 is started. The machining drill bit 412 rotates at high speed under the drive of the second motor 411 and begins to perform precision machining on the steel wheel. The externally installed protective cover 48 can block the debris generated during the machining of the steel wheel to prevent the debris from splashing to the outside. The debris that falls on the machine base 1 can fall into the collection frame 8 at the lower end through the through hole 2 to achieve a certain cleaning effect.
[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
