[0007] According to the above technical solution, a No. 1 spring is arranged between the limit rod and the fixed plate, and the limit rod is reset by the No. 1 spring. The top of the limit rod is arranged as an inclined plane, and a tray is arranged at the movable end of the elastic telescopic rod 1. By placing the uncut steel ring on the sliding frame, the steel ring will contact the tray, so that the movable end of the elastic telescopic rod 1 moves downward, and the bottom of the steel ring is supported by the tray.

The upper and lower sides of the clamping block are set as inclined surfaces, and a No. 3 spring is arranged between the clamping block and the L-shaped rod. The movement of the movable end of the elastic telescopic rod 2 drives the movement of the servo motor 2, and the movement of the servo motor 2 drives the grinding wheel to move and contact the cut part of the steel ring. At this time, the grinding wheel is driven to rotate by the rotation of the output end of the servo motor 2, and then the top rod is driven to rotate by the rotation of the output end of the servo motor 1, so as to grind the burr, and the clamping block is reset by the arranged No. 3 spring.

[0013] According to the above technical solution, the grinding device also includes a limit button and a sliding rod, the limit button is fixedly installed on the movable end of the elastic telescopic rod 2, one side of the sliding rod is fixedly installed on the surface of the limit button close to the side of the slide plate, and the other side of the sliding rod is slidably installed on the inner wall of the slide plate, so that when the top rod is reset, the movable end of the elastic telescopic rod 2 is driven to move, that is, the movable end of the elastic telescopic rod 2 is contracted by the movement of the sliding rod until the limit button contacts the inclined surface of the block when reset, and is continued to be restricted to a compressed state by the block.

[0014] The present invention provides a vehicle wheel steel rim production device having the following beneficial effects: (1) The invention, through the setting of the cutting device, places the uncut steel ring on the sliding frame, and supports the bottom of the steel ring through the tray and the elastic telescopic rod. When the bottom of the steel ring is effectively supported, the operator can perform the cutting operation more confidently without frequently adjusting the position of the steel ring or worrying about accidental movement during the cutting process. The movable end of the electric push rod is in the maximum extension state by default, and the steel ring is clamped by the electric push rod, the fixed frame, the connecting rod, the sliding frame, the slide rail rod, the fixed plate, the round rod, and the clamping plate. When the clamping force of the clamping plate is too large, the sliding frame cannot continue to move by the round rod, the limit rod, and the triangular groove. In this way, the steel ring is prevented from being pinched, which can reduce the rework work required due to damaged steel rings. If the steel ring is clamped with a pit during clamping, it may require additional processing steps to repair it, which will increase production time and cost. After the steel ring is clamped, it is laser cut by the welding arm.

[0015] (2) The invention, through the setting of auxiliary devices, uses an elastic telescopic rod, a connecting button, and a splash plate to prevent splashing during cutting. A large amount of sparks will be splashed during laser cutting, which poses a safety hazard. The splash plate can block these splashing sparks to prevent them from damaging the equipment, while also protecting the safety of the operator. When cutting is not required, the splash plate is in a storage state, which helps to save operating space. After one week of cutting, the ejector rod will eject the cut waste. The cutting area may be hot, and if the operator is picked up manually, it may cause burns. The automatic ejection by the ejector rod can prevent the operator from directly contacting the cutting area, thereby improving work safety.

[0016] (3) The invention, through the setting of the grinding device, when the ejector pushes out the cut waste, a cut area appears in the center of the steel ring. These areas may have burrs, which need to be removed by grinding to make the edges smooth and flat for subsequent processing and assembly. The burrs are ground through the ejector, the fixing button, the second elastic telescopic rod, the limit button, the second servo motor, and the grinding wheel. The movement of the limit button drives the sliding rod to move along the inner wall of the slide plate. When the ejector is reset, the movable end of the second elastic telescopic rod is driven to move, that is, the movable end of the second elastic telescopic rod is contracted by the movement of the sliding rod until the limit button contacts the inclined surface of the block when it is reset, and is further restricted to a compressed state by the block. The automatic reset function can quickly return the grinding device to its initial position to prepare for the next grinding operation. This is crucial for efficient operation in continuous production because it can reduce equipment downtime and improve overall production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

In this way, the steel ring 3 is protected from pinching, which can reduce the rework work required due to damage to the steel ring 3. If the steel ring 3 is clamped out of a pit during clamping, additional processing steps may be required to repair it, which will increase production time and cost.

[0021] A No. 1 spring is arranged between the limit rod 12 and the fixed plate 9, and the limit rod 12 is reset by the No. 1 spring. The top of the limit rod 12 is arranged as an inclined plane, and the movable end of the elastic telescopic rod 14 is arranged with a tray, and the bottom of the steel ring 3 is supported by the tray.

The pressure rod 23 is fixedly installed on the movable end of the elastic telescopic rod 14, and the cross 24 is fixedly installed on the fixed end of the elastic telescopic rod 14. When cutting is not required, the splash plate 21 is in a storage state through the pressure rod 23 and the cross 24, which helps to save operating space.

The automatic ejection of the push rod 25 can prevent the operator from directly contacting the cutting area, thereby improving the safety of the work. The push rod 25 is reset by the No. 2 spring.

[0026] The grinding device includes a slide plate 30, a fixing button 31, an elastic telescopic rod 2 32 and an L-shaped rod 33. The slide plate 30 is fixedly installed on the top of the cross 24, the fixing button 31 is fixedly installed on the circumferential surface of the top rod 25, the fixed end of the elastic telescopic rod 2 32 is fixedly installed inside the fixing button 31, and the L-shaped rod 33 is fixedly installed on the top of the cross 24. When the top rod 25 is reset, the movable end of the elastic telescopic rod 2 32 is driven to move, that is, the movable end of the elastic telescopic rod 2 32 is moved and contracted by the sliding rod 38 until the limit button 37 contacts the inclined surface of the block 34 when reset, and is continued to be restricted to a compressed state by the block 34.

The upper and lower sides of the block 34 are set as inclined surfaces. A No. 3 spring is arranged between the block 34 and the L-shaped rod 33. The block 34 is reset by the No. 3 spring.

[0029] When the present embodiment is working, the movable end of the elastic telescopic rod 14 moves downward to drive the connecting button 22 to rotate, and the connecting button 22 rotates to drive the splash plate 21 to rotate in the direction of the steel ring 3 until it is parallel to the steel ring 3. In this way, splash protection is achieved during cutting. A large amount of sparks will be splashed during laser cutting, which poses a safety hazard. The splash plate 21 can block these splashing sparks to prevent them from damaging the equipment, while also protecting the safety of the operator. When no cutting is required, the splash plate 21 is in a storage state, which helps to save operating space. The movable end of the elastic telescopic rod 14 moves downward and drives the pressure rod 23 to move. The movement of the pressure rod 23 drives the movement of the X-shaped plate 27.

After one week of cutting, the push rod 25 will eject the cut waste. There may be high temperature in the cutting area. If it is directly taken manually, it may cause burns to the operator.

When the ejector rod 25 ejects the cut waste, a cut area appears in the center of the steel ring 3. These areas may have burrs, which need to be removed by grinding to make the edges smooth and flat for subsequent processing and assembly. The elastic telescopic rod 2 32 is now restricted by the limit button 37 and is in a compressed state. At this time, the ejector rod 25 moves upward to drive the fixing button 31 to move, and the movement of the fixing button 31 drives the fixed end of the elastic telescopic rod 2 32 to move, that is, when the elastic telescopic rod 2 32 moves, it will drive the limit button 37 to move. The movement of the limit button 37 will contact the inclined surface of the block 34, so that the block 34 compresses the No. 3 spring toward the inside of the L-shaped rod 33 at the same time. At this time, the limit button 37 is separated from the restriction of the block 34, so that the movable end of the elastic telescopic rod 2 32 is extended, and the movement of the movable end of the elastic telescopic rod 2 32 drives the servo motor 2 35 to move, and the movement of the servo motor 2 35 drives the grinding wheel 36 to move and contact with the steel ring 3 is in contact with the cut part, at this time, the grinding wheel 36 is driven to rotate by the output end of the servo motor 2 35, and then the push rod 25 is driven to rotate by the output end of the servo motor 1 26 to grind the burr, and when the movable end of the elastic telescopic rod 2 32 is extended, the limit button 37 is driven to move, and the movement of the limit button 37 drives the sliding rod 38 to move along the inner wall of the slide plate 30, and when the push rod 25 is reset, the movable end of the elastic telescopic rod 2 32 is driven to move, that is, the movable end of the elastic telescopic rod 2 32 is contracted by the movement of the sliding rod 38, until the limit button 37 contacts the inclined surface of the block 34 when reset, and is continued to be restricted to the compression state by the block 34, and the grinding device can be quickly returned to the initial position through the automatic reset function to prepare for the next grinding operation, which is very important for efficient operation in the continuous production process, because it can reduce the downtime of the equipment and improve the overall production efficiency.
