An L-shaped frame 10 connected to the drive control assembly 7 is slidably arranged inside the transmission control plate 11 to cooperate with the drive control assembly 7 to complete the synchronous drive of the clamping assemblies on both sides.

[0036] In this embodiment, the piston component 13 includes a first piston slidably disposed inside the piston tube 14 and a first push rod fixedly connected to the first piston. The other end of the first push rod is fixedly connected to the transmission control plate 11. The drive control component 7 can cooperate with the L-shaped frame 10 to drive the transmission control plate 11 to move laterally along the positioning block 12. The transmission control plate 11 drives the piston component 13 to move inside the piston tube 14, thereby driving the air flow inside the cavity 15 to complete the drive of the clamping component. The clamping component completes the clamping and locking of the helmet. Subsequently, the lifting component 8 realizes the longitudinal movement of the lifting column 9 under the drive of the drive control component 7. The transmission control plate 11 moves up and down synchronously with the lifting column 9 to ensure the effectiveness and reliability of the clamping component in clamping the helmet. By setting the support component, it can not only cooperate with the drive control component 7 to complete the clamping and locking of the helmet, but also make flexible lifting and lowering after clamping, thereby enabling the equipment to perform comprehensive and effective grinding of the helmet.

[0037] In one embodiment of the present invention, please refer to Figure 4 and Figure 5 The clamping assembly includes: a positioning tube 16, a locking clamp 17, a sensing piston 19, a fixing rod 20, a guide block 21, and a guide groove 22. The positioning tube 16 is symmetrically arranged on both sides of the lifting column 9, fixedly connected to the lifting column 9, and connected to the cavity 15 on the same side. The sensing piston 19 is slidably arranged inside the positioning tube 16. A spring is fixedly arranged between the sensing piston 19 and the inner wall of the positioning tube 16.

A guide block 21 fixedly connected to the positioning tube 16 is slidably arranged inside the guide groove 22. The other end of the fixing rod 20 is fixedly connected to the locking clamp 17.

[0038] In this embodiment, the locking clip 17 has a U-shaped structure, and the fixing rod 20 is fixedly connected to the middle of the locking clip 17. When the piston 13 moves inside the piston tube 14, the air inside the cavity 15 enters the positioning tube 16, and the sensing piston 19 moves accordingly. The sensing piston 19 drives the fixing rod 20 to move. The guide block 21 cooperates with the guide groove 22 to guide and limit the fixing rod 20. The fixing rod 20 drives the locking clip 17 to move. The locking clips 17 on both sides cooperate with each other to complete the clamping and locking of the helmet from the inside of the helmet. Subsequently, the lifting column 9 drives the helmet to move upward, which facilitates the all-round grinding of the helmet surface around the grinding unit 4. Rubber balls are fixedly provided on the outer sides of both ends of the locking clip 17. On the one hand, the helmet is protected when clamping, and on the other hand, the effectiveness and stability of clamping are ensured.

[0039] In one embodiment of the present invention, please refer to Figure 7The drive control component 7 includes: a control motor 23, a bidirectional screw 24, a guide control 25, a movable frame 26, and a connecting seat 27.

[0040] In this embodiment, the guide control 25 includes a second push rod fixedly mounted on the movable frame 26 and a second piston fixedly connected to the other end of the second push rod. The second piston cooperates with the lifting assembly 8. When the control motor 23 drives the bidirectional screw 24 to rotate, the bidirectional screw 24 can drive the movable frames 26 on both sides to move synchronously in opposite directions. The movable frame 26 drives the transmission control plate 11 to move synchronously through the connecting seat 27 and the spring, thereby completing the driving of the locking clip 17. As the movable frame 26 continues to move, the spring located between the connecting seat 27 and the L-shaped frame 10 is stretched. The movable frame 26 drives the guide control 25 to connect with the lifting assembly 8, thereby completing the driving of the lifting assembly 8. The lifting assembly 8 realizes the lifting of the lifting column 9, thereby completing the lifting of the helmet, which facilitates the equipment to grind the corners of the helmet and ensures the comprehensiveness of the grinding.

[0041] In one embodiment of the present invention, please refer to Figure 8 The lifting assembly 8 includes: a control box 28, a lifting control tube 29, a control piston 30, a control groove 31, and a control tube 32.

The control piston 30 is slidably connected to the control groove 31 arranged inside the lifting column 9.

[0042] In this embodiment, the movable frame 26 drives the guide control 25 into the inner side of the guide control tube 32, thereby driving the air inside the guide control box 28 to enter the inner side of the control slot 31 along the lifting control tube 29. In conjunction with the control piston 30, the lifting column 9 is raised and lowered. The lifting control tubes 29 on both sides of the guide control box 28 are arranged symmetrically at the center. By setting the lifting component 8, the lifting column 9 can be raised after the clamping component has completed clamping and locking the helmet, which facilitates the all-round grinding of the helmet by the grinding unit 4.

[0043] In one embodiment of the present invention, please refer to Figure 9 and Figure 10The surrounding grinding unit 4 includes: a ring support frame 33, a rotary motor 34, a support frame 35, a lifting plate 36, a take-up and put-down rack 37, a detector 42, a mounting base 43, a tilting motor 44, and a grinding machine 45.

A detector 42 connected to the take-up and release frame 37 is installed on the outside of the grinder 45.

[0044] In this embodiment, both the retraction control component 38 and the lifting control component 41 are electric push rods. One end of the connecting rod 40 is rotatably connected to the control block 39, and the other end is rotatably connected to the retraction frame 37. The belt component includes a pulley fixedly mounted on the outside of the support ring frame 33 and the output end of the rotary motor 34, and a belt for connecting the pulley. When the helmet is locked and raised, the lifting control component 41 controls the lifting plate 36 to rise and fall. The retraction control component 38, through the control block 39 and the connecting rod 40, realizes the retraction and extension of the retraction frame 37, and adjusts the height of the grinder 45 and the distance between the grinder 45 and the helmet. Subsequently, the flip motor 44... Mounting base 43 adjusts the angle of grinding machine 45, and in conjunction with detector 42, enables grinding machine 45 to precisely grind the helmet. Subsequently, rotary motor 34 drives support ring frame 33 to rotate via pulleys and belts, and grinding machine 45 rotates around the helmet.

By setting up a surrounding grinding unit 4, the height, distance, and angle of grinding machine 45 can be adjusted after the helmet is locked and lifted, and the grinding machine 45 can rotate around the helmet, thereby enabling the equipment to perform comprehensive and effective automated grinding of the helmet.

[0045] In one embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 11It also includes: a dustproof unit 5, which is arranged around the outside of the placement platform 2 and connected to the base 1, for real-time collection of dust generated during grinding. The dustproof unit 5 includes: a rotating rod 18, a suction pipe 46, a cleaning motor 47, a filter cartridge 48, a suction pump 49, a filter frame 50, and a cleaning brush 51. The filter cartridge 48 is fixedly installed on the top of the inner side of the base 1. Several suction pipes 46 are arranged around the outside of the filter cartridge 48. One end of the suction pipe 46 is connected to the filter cartridge 48, and the other end is located on the outside of the placement platform 2.

[0046] In this embodiment, a protective shell is provided on the outside of the cleaning motor 47. The protective shell is fixedly installed on the top of the inner side of the filter cartridge 48. When grinding is in progress, the dust pump 49 runs, and dust enters the inner side of the filter cartridge 48 along the dust suction pipe 46. The filter frame 50 filters the dust, and the air after dust removal is discharged to the outside of the platform 1 along the dust pump 49. The cleaning motor 47 drives the rotating rod 18 to rotate, and the rotating rod 18 cleans the filter frame 50 through the cleaning brush 51 to prevent the filter frame 50 from clogging during operation, thus ensuring the stability of the dust removal equipment during operation. By setting the dustproof unit 5, the dust generated during the processing can be quickly recovered to prevent dust from escaping to the outside of the equipment, which is beneficial to environmental protection. At the same time, it can automatically clean the filter frame 50 during operation, improving the continuity and stability of the equipment during operation.

[0047] The working principle of this helmet shell grinding equipment is as follows:

[0048] Helmet positioning and clamping: The worker places the helmet upside down on the placement platform 2. After the machine is started, the control motor 23 inside the placement platform 2 drives the bidirectional screw 24 to rotate. The bidirectional screw 24 causes the movable frames 26 on both sides to move equidistantly to both sides. The movable frames 26 move synchronously through the connecting seat 27 and the spring, which drives the transmission control plate 11. The L-shaped frame 10 drives the transmission control plate 11 to move laterally along the positioning block 12. The transmission control plate 11 drives the piston 13 to move inside the piston tube 14. The air inside the cavity 15 enters the positioning tube 16. The sensing piston 19 moves laterally accordingly. The fixing rod 20 drives the locking clip 17 to move. The locking clips 17 on both sides cooperate with each other to clamp and lock the helmet from the inside.

[0049] Height increase: After clamping the helmet, the movable frame 26 continues to move, and the spring located between the connecting seat 27 and the L-shaped frame 10 is stretched. The movable frame 26 drives the guide control 25 into the inside of the guide control tube 32, which in turn drives the air inside the guide control box 28 to enter the inside of the control slot 31 along the lifting control tube 29. In conjunction with the control piston 30, the lifting column 9 is raised.

[0050] Automatic polishing: First, the detector 42 scans the shape of the helmet surface, the lifting control component 41 controls the lifting plate 36 to rise and fall, and the retraction control component 38, through the control block 39 and the connecting rod 40, realizes the retraction and extension of the retraction frame 37, and adjusts the height of the polishing machine 45 and the distance between the polishing machine 45 and the helmet. Then, the flip motor 44 adjusts the angle of the polishing machine 45 through the mounting base 43, and in conjunction with the detector 42, enables the polishing machine 45 to precisely polish the helmet.
