Description

Technical Field

[0001] This application relates to the field of safety helmet processing technology, and in particular to a punching device for safety helmet processing. Background Technology

[0002] Safety helmets are suitable for general workplaces and have basic protective performance, which can protect against injuries caused by falling objects and other specific factors. In order to ensure the safety of safety helmets, they need to be tested. Safety helmet tests are usually to ensure that safety helmets can protect the user's head under various conditions and prevent injuries caused by accidental collisions or falls.

[0003] To install buckle structures such as chin straps on safety helmets, drilling equipment is needed to create holes. While current drilling equipment can drill holes in safety helmets, the varying sizes of helmets make it difficult to position the drill correctly, leading to helmet slippage during drilling and affecting accuracy. Therefore, improvements are needed. Utility Model Content

[0004] To facilitate the positioning of safety helmets, this application provides a punching device for processing safety helmets.

[0005] The drilling device for processing safety helmets provided in this application adopts the following technical solution: A drilling device for processing safety helmets includes a carrier plate, a control panel fixedly mounted on the upper surface of the carrier plate, a positioning component above the carrier plate, a driving component below the carrier plate, a control end of the driving component extending into the interior of the positioning component, a pressure application component above the carrier plate, and a drilling component above the carrier plate.

[0006] Optionally, the positioning component includes a head mold mounted on the upper surface of the carrier plate. The outer surface of the head mold has two sets of openings. Each opening has a top block slidably mounted on its inner wall. The two sets of top blocks have slag discharge holes on their opposite sides and metal blocks are fixedly mounted on their opposite sides.

[0007] By adopting the above technical solution, the cooperation between the opening and the top block allows the top block to move inside the opening, and the metal block can be pushed by the conical magnetic block to control the metal block and the top block to move away from each other, so that the top block can extend out of the opening to position the safety helmet.

[0008] Optionally, the drive assembly includes a bracket mounted on the bottom surface of the carrier plate, a servo motor fixedly mounted on the bottom surface of the bracket, a threaded rod fixedly mounted on the output end of the servo motor, a threaded tube threadedly connected to the outer surface of the threaded rod, and a conical magnetic block fixedly mounted on the top end of the threaded tube, with each metal block attracting the conical magnetic block.

[0009] By adopting the above technical solution, the servo motor can provide power to the threaded rod, causing the threaded rod to rotate. By utilizing the threaded connection between the threaded rod and the threaded tube, the up-and-down movement of the conical magnetic block can be controlled.

[0010] Optionally, the drilling assembly includes two sets of spiral cylinders mounted on the upper surface of the carrier plate. Each spiral cylinder has a connecting shaft fixedly mounted at its output end, and a drill bit is fixedly mounted at the end of each connecting shaft away from the spiral cylinder.

[0011] Optionally, the pressure application assembly includes an L-shaped plate mounted on the upper surface of the carrier plate, an electric push rod fixedly mounted on the upper surface of the L-shaped plate, a push plate fixedly mounted on the telescopic end of the electric push rod, and a rubber pad fixedly mounted on the bottom surface of the push plate.

[0012] By adopting the above technical solution, the electric push rod pushes the push plate, which in turn pushes the rubber pad to contact the safety helmet, thereby performing secondary positioning of the safety helmet and making it more stable.

[0013] Optionally, the bracket has sliding grooves on both the left and right sides, and a slide bar is slidably installed on the inner wall of each sliding groove. The sides of the two slide bars that are close to each other are fixedly installed on the outer surface of the threaded tube.

[0014] By adopting the above technical solution, the combination of the slide bar and slide groove can limit the threaded tube and prevent the threaded tube from rotating with the thread.

[0015] Optionally, two sets of support legs are fixedly installed on the bottom surface of the carrier plate, and a foot cup is fixedly installed at the bottom end of each support leg.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a spiral cylinder, connecting shaft, and drill bit, the drill bit can drill holes in the safety helmet. The servo motor, threaded rod, threaded tube, and conical magnetic block can control the up-and-down movement of the conical magnetic block, allowing it to control the metal blocks to move closer and further apart. The top block can extend out of the opening to position safety helmets of different sizes. Combined with an electric push rod, push plate, and rubber pad, the safety helmet can be further limited, improving the stability of the safety helmet during drilling and effectively preventing side slippage during drilling, thus improving drilling accuracy. 2. Place the safety helmet outside the head mold. The servo motor drives the threaded rod to rotate. Under the action of the slide bar and slide groove, the threaded rod pushes the threaded tube upward. The threaded tube pushes the conical magnetic block upward, pushing the metal blocks away from each other. The metal blocks push the top block to move along the opening direction, positioning the safety helmet. Then, the electric push rod is activated to push the push plate downward, so that the rubber pad contacts the safety helmet, positioning the safety helmet again and effectively preventing it from slipping. Then, the spiral cylinder is activated to control the connecting shaft and drill bit to drill a hole in the safety helmet. The waste generated during drilling can enter the slag discharge hole for discharge. After drilling is completed, the electric push rod is reset and the servo motor is reversed, so that the threaded rod and the threaded tube control the conical magnetic block to move downward. The magnetic force pulls the metal blocks closer together, causing the top block to retract into the opening, releasing the positioning of the safety helmet, allowing the worker to remove the drilled safety helmet.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a punching device for processing safety helmets. (Refer to...) Figure 1The drilling device for processing safety helmets includes a carrier plate 1, a control panel 103 fixedly installed on the upper surface of the carrier plate 1, a positioning component 4 above the carrier plate 1, a driving component 5 below the carrier plate 1, the control end of the driving component 5 extending into the interior of the positioning component 4, a pressure application component 3 above the carrier plate 1, and a drilling component 2 above the carrier plate 1.

[0024] Reference Figure 3 The positioning component 4 includes a head mold 401 mounted on the upper surface of the carrier plate 1. The outer surface of the head mold 401 has two sets of openings 402. Each opening 402 has a top block 403 slidably mounted on its inner wall. The two sets of top blocks 403 have a slag discharge hole 404 on their opposite sides. The two sets of top blocks 403 have a metal block 405 fixedly mounted on their opposite sides. By the cooperation of the openings 402 and the top blocks 403, the top blocks 403 can move inside the openings 402. The metal blocks 405 can be pushed by the conical magnetic block 505 to control the metal blocks 405 and the top blocks 403 to move away from each other, so that the top blocks 403 can extend out of the openings 402 to position the safety helmet.

[0025] Reference Figure 4 The drive assembly 5 includes a bracket 501 mounted on the bottom surface of the carrier plate 1. A servo motor 502 is fixedly mounted on the bottom surface of the bracket 501. A threaded rod 503 is fixedly mounted on the output end of the servo motor 502. A threaded tube 504 is threadedly connected to the outer surface of the threaded rod 503. A conical magnetic block 505 is fixedly mounted on the top end of the threaded tube 504. Each metal block 405 is attracted to the conical magnetic block 505. The servo motor 502 can provide power to the threaded rod 503, enabling the threaded rod 503 to rotate. The threaded connection between the threaded rod 503 and the threaded tube 504 can control the up and down movement of the conical magnetic block 505.

[0026] Reference Figure 1 The drilling assembly 2 includes two sets of spiral cylinders 201 mounted on the upper surface of the carrier plate 1. Each spiral cylinder 201 has a connecting shaft 202 fixedly mounted at its output end. Each connecting shaft 202 has a drill bit 203 fixedly mounted at its end away from the spiral cylinder 201. The spiral cylinder 201 can provide power to the connecting shaft 202, enabling the connecting shaft 202 to rotate and extend, thereby controlling the drill bit 203 to drill holes in the safety helmet.

[0027] Reference Figure 2The pressure application component 3 includes an L-shaped plate 301 installed on the upper surface of the carrier plate 1. An electric push rod 302 is fixedly installed on the upper surface of the L-shaped plate 301. A push plate 303 is fixedly installed on the telescopic end of the electric push rod 302. A rubber pad 304 is fixedly installed on the bottom surface of the push plate 303. The electric push rod 302 can push the push plate 303, causing the push plate 303 to push the rubber pad 304 to contact the safety helmet, thereby performing secondary positioning of the safety helmet and making the safety helmet more stable.

[0028] Reference Figure 4 The bracket 501 has a sliding groove 506 on both the left and right sides. A sliding strip 507 is slidably installed on the inner wall of each sliding groove 506. The sides of the two sliding strips 507 that are close to each other are fixedly installed on the outer surface of the threaded tube 504. Through the cooperation of the sliding strip 507 and the sliding groove 506, the threaded tube 504 can be limited to prevent the threaded tube 504 from rotating with the threaded rod 503.

[0029] Reference Figure 1 Two sets of support legs 101 are fixedly installed on the bottom surface of the carrier plate 1. Each support leg 101 has a foot cup 102 fixedly installed at its bottom end. The device can be adjusted to be level by the cooperation of the support leg 101 and the foot cup 102.

[0030] The implementation principle of the drilling device for processing safety helmets in this embodiment is as follows: First, the safety helmet is placed outside the head mold 401. Then, the servo motor 502 is started, driving the threaded rod 503 to rotate. As the threaded rod 503 rotates, the threaded tube 504, threadedly connected to the threaded rod 503, is pushed upwards by the slide bar 507 and the slide groove 506. This allows the threaded tube 504 to push the conical magnetic block 505 upwards. As the conical magnetic block 505 moves upwards, it pushes the metal blocks 405 away from each other, and the metal blocks 405 push the top block 403 to move along the opening 402, allowing the top block 403 to position the safety helmet. Then, the electric push rod 302 is started, causing the electric push rod 302 to push the push plate 303 towards... The device moves downwards, causing the rubber pad 304 to contact the safety helmet and reposition it, effectively preventing slippage. Then, the spiral cylinder 201 is activated, controlling the connecting shaft 202 and the drill bit 203 to drill a hole in the safety helmet. The waste generated during drilling can enter the slag discharge hole 404, allowing it to be discharged. After drilling is completed, the electric push rod 302 is reset, and the servo motor 502 is reversed, causing the threaded rod 503 to work with the threaded tube 504 to control the conical magnetic block 505 to move downwards. As the conical magnetic block 505 moves downwards, the magnetic force pulls the metal blocks 405 closer together, causing the top block 403 to retract into the opening 402, releasing the safety helmet from its position, allowing the worker to remove the drilled safety helmet.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
