Description

Technical Field

[0001] This invention relates to the technical field of helmet manufacturing, specifically a production apparatus for a bulletproof ceramic helmet. Background Technology

[0002] Bulletproof helmets are equipment that can absorb and dissipate the energy of bullets, prevent penetration, reduce blunt force trauma, and effectively protect the human head. Due to the advantages of boron carbide ceramics, such as low density (2.52 g / cm3), high melting point (2450℃), high hardness (second only to diamond and cubic boron nitride), and good thermal neutron absorption capacity, they are also often used in the manufacture of bulletproof helmets.

[0003] In the production process of bulletproof ceramic helmets, holes need to be drilled in order to attach cushioning pads and straps to the helmets. Currently, hand drills and bench drills are used to drill these holes. However, the holes cannot be guaranteed to be perpendicular to the helmet surface at that point, which can easily cause slippage and deviation. The drilling position accuracy error is relatively large, which affects the helmet suspension installation. In addition, it is time-consuming and labor-intensive, which affects work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a production device for bulletproof ceramic helmets, which solves the problem of drilling deviation and improves the production efficiency and quality of bulletproof ceramic helmets.

One end of the scissor arm is rotatably connected to both the arc-shaped base frame and the arc-shaped guide rail. A first cylinder is provided on the arc-shaped base frame. The movable end of the first cylinder is connected to one of the scissor arms, and one end of the other scissor arm is slidably connected to the arc-shaped guide rail.

[0008] Furthermore, the bottom of the movable seat is slidably connected to the first slider of the arc-shaped guide rail. The arc-shaped guide rail has grooves on both sides. The end of the first slider is provided with a protrusion that is slidably connected to the groove. The arc-shaped guide rail is provided with a first motor. The movable end of the first motor is provided with a drive block. The two ends of the drive block are respectively provided with a first connecting block between them and the movable seat.

[0009] Furthermore, one end of the movable seat is rotatably connected to the rotating plate, and the other end of the movable seat is symmetrically rotatably connected to a second connecting block. A sliding rod is provided between the ends of the two second connecting blocks, and a sliding groove is provided at the bottom of the rotating plate to slide in connection with the sliding rod.

[0010] Furthermore, the movable seat is provided with a second cylinder, the movable end of the second cylinder is provided with a push block, the end of the push block is rotatably connected to a first support rod, and the other end of the first support rod is rotatably connected to the middle of the second connecting block.

[0011] Furthermore, the fixed base is provided with a second motor, the movable end of the second motor is provided with a screw threadedly connected to the clamping platform, the fixed base is provided with symmetrical linear slide rails, and the bottom of the clamping platform is provided with a second slider that is slidably connected to the linear slide rails.

[0012] Furthermore, the clamping platform is provided with bolts and adjustment holes for drill bits to pass through. One side of the adjustment hole is open. The clamping platform is provided with a through hole that connects to the adjustment hole. The bolt passes through the through hole and is threadedly connected to the clamping platform.

[0013] Furthermore, the fixing fixture also includes an upper base that slides vertically and a lower base that slides horizontally. Both the upper base and the lower base are provided with T-slots. T-blocks are symmetrically slidably connected in the T-slots. A third connecting block is rotatably connected to the end of each T-block. The other ends of the plurality of third connecting blocks are rotatably connected to a first fixing block and a second fixing block, respectively. A clamping spring is provided between two T-blocks.

[0014] Furthermore, the upper base and the lower base are symmetrically rotatably connected with second support rods, the ends of the second support rods are respectively rotatably connected to the third connecting block, the fixing fixture also includes a guide rod slidably connected to the lower base and a guide block slidably connected to the upper base, and a third cylinder is provided between the guide block and the upper base.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By sliding the two first fixing blocks and the two second fixing blocks symmetrically in the horizontal and vertical directions respectively, their ends are inserted into the inner and outer sides of the helmet respectively, thereby achieving the fixation of the helmet in the horizontal, vertical and vertical directions, and avoiding the displacement of the bulletproof ceramic helmet during the drilling process, which would affect the drilling quality.

[0017] 2. The drill bit's Z-axis position is adjusted by sliding on several arc-shaped guide rails on the arc-shaped base; the drill bit's X and Y-axis positions are adjusted by sliding on the arc-shaped guide rails via the movable seat; the angle between the drill bit and the bulletproof ceramic helmet is adjusted by rotating the rotating plate on the movable seat, thereby moving the rotating head to the designated position and vertically aligning it with the bulletproof ceramic helmet, preventing the drill bit from slipping or deviating during the drilling process, which would affect the production quality of the bulletproof ceramic helmet.

[0018] 3. When it is necessary to adjust the position and angle of the drill bit, the first cylinder and the scissor arm work together to move the arc-shaped guide rail on the arc-shaped base frame, adjusting the position of the drill bit in the Z direction; the first motor, the slide rail, the drive block, and the first connecting block work together to move the movable seat symmetrically on the arc-shaped guide rail, making the two hole positions symmetrical about the center of the slide rail, adjusting the position of the drill bit in the X and Y directions; the second cylinder, the push block, the movable seat, the first support rod, the protrusion, the second connecting rod, the slide rod, the rotating plate, and the slide groove work together to adjust the angle between the drill bit and the bulletproof ceramic helmet, so that the drill bit moves to the designated position and is perpendicular to the bulletproof ceramic helmet, avoiding the bulletproof ceramic helmet from shifting during the drilling process and affecting the drilling quality. In addition, the first support rod can share part of the force applied to the second connecting block, thereby ensuring the overall stability.

[0019] 4. When it is necessary to fix the bulletproof ceramic helmet, the cooperation between the bulletproof ceramic helmet, the first fixing block, the third connecting block, the T-block, the clamping spring, the second cylinder, and the second fixing block is used until the overall structure is in a stable state, thereby achieving the horizontal, vertical, and longitudinal fixation of the bulletproof ceramic helmet. This prevents the bulletproof ceramic helmet from shifting during the drilling process and affecting the drilling quality. In addition, the upper base and the lower base are symmetrically rotatably connected to the second support rods, and the ends of the second support rods are rotatably connected to the third connecting block, thereby bearing part of the force applied to the third connecting block and ensuring the stability of the overall structure.

[0028] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0029] This invention provides a production apparatus for bulletproof ceramic helmets, such as... Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the device includes several drilling mechanisms 1, a fixing fixture 3 for securing the bulletproof ceramic helmet 2, and an adjusting mechanism 4 for driving the drilling mechanism 1 to move. The fixing fixture 3 secures the bulletproof ceramic helmet 2, preventing it from shifting during the drilling process and affecting the drilling quality. Then, the adjusting mechanism 4 adjusts the position of the drill bit 8, moving it to a designated position and vertically aligning it with the bulletproof ceramic helmet 2, preventing the drill bit 8 from slipping or deviating during the drilling process, which would affect the production quality of the bulletproof ceramic helmet 2. Finally, the drilling mechanism 1 drills multiple points on the bulletproof ceramic helmet 2. The drilling process involves a fixing fixture 3 comprising a first fixing block 5 that slides symmetrically laterally and a second fixing block 6 that slides longitudinally. The end of the first fixing block 5 contacts the inner side of the bulletproof ceramic helmet 2, and the end of the second fixing block 6 contacts the outer side of the bulletproof ceramic helmet 2. By sliding the two first fixing blocks 5 and the two second fixing blocks 6 symmetrically laterally and longitudinally, respectively, their ends are inserted into the inner and outer sides of the bulletproof ceramic helmet 2, thereby achieving horizontal, longitudinal, and vertical fixation of the bulletproof ceramic helmet 2 and avoiding the need for drilling. The offset of the bulletproof ceramic helmet 2 affects the drilling quality; the drilling mechanism 1 includes a fixed base 7 set on the adjustment mechanism 4 and a drill bit 8 set perpendicular to the bulletproof ceramic helmet 2. The drill bit 8 drills holes at multiple points on the bulletproof ceramic helmet 2; a clamping platform 9 that cooperates with the drill bit 8 is slidably connected to the fixed base 7, fixing the drill bit 8 on the clamping platform 9. The clamping platform 9 slides obliquely downward on the fixed base 7, driving the drill bit 8 to move until the end of the drill bit 8 contacts the bulletproof ceramic helmet 2 and gradually penetrates the bulletproof ceramic helmet 2, thereby improving the quality of the bulletproof ceramic helmet. 2. Drilling is performed at multiple points; the adjustment mechanism 4 includes an arc-shaped base frame 10, on which several arc-shaped guide rails 11 are slidably connected to adjust the Z-direction position of the drill bit 8. Several movable seats 12 are slidably connected to the arc-shaped guide rails 11 to adjust the X and Y-direction positions of the drill bit 8. A rotating plate 13 connected to the fixed seat 7 is rotatably connected to the movable seat 12 to adjust the angle between the drill bit 8 and the bulletproof ceramic helmet 2, so that the drill bit 8 is perpendicular to the bulletproof ceramic helmet 2, thus preventing the bulletproof ceramic helmet 2 from shifting during the drilling process and affecting the drilling quality.

[0030] Preferred, such as Figure 2 and Figure 3 As shown, a scissor arm 14 is intersected between the arc-shaped base frame 10 and the arc-shaped guide rail 11. One end of the scissor arm 14 is rotatably connected to both the arc-shaped base frame 10 and the arc-shaped guide rail 11. A first cylinder 15 is provided on the arc-shaped base frame 10. The movable end of the first cylinder 15 is connected to one of the scissor arms 14, and one end of the other scissor arm 14 is slidably connected to the arc-shaped guide rail 11. By extending or retracting the movable end of the first cylinder 15, one end of one of the scissor arms 14 is driven to move, causing the two scissor arms 14 to open or close relative to each other, thereby driving the arc-shaped guide rail 11 to move on the arc-shaped base frame 10 and adjusting the Z-direction position of the drill bit 8.

[0031] Preferred, such as Figure 2 and Figure 3 As shown, the bottom of the movable seat 12 is slidably connected to the arc-shaped guide rail 11 by a first slider 16. The arc-shaped guide rail 11 has grooves 17 on both sides. The end of the first slider 16 has a protrusion 18 that is slidably connected to the grooves 17, which guides the sliding of the movable seat 12 on the arc-shaped guide rail 11. The arc-shaped guide rail 11 is equipped with a first motor 19. The movable end of the first motor 19 is equipped with a drive block 20. The two ends of the drive block 20 are respectively equipped with first connecting blocks 21 between them and the movable seat 12. The two ends of the first connecting blocks 21 are rotatably connected to the drive block 20 and the movable seat 12, respectively. The first motor 19 drives the drive block 20 to rotate, which in turn drives one end of the corresponding first connecting block 21 to make a circular motion. Since the two ends of the first connecting block 21 are rotatably connected to the drive block 20 and the movable seat 12, the movable seat 12 is slidably moved on the arc-shaped guide rail 11, thereby adjusting the X and Y position of the drill bit 8.

[0032] Preferred, such as Figure 2 and Figure 3 As shown, one end of the movable seat 12 is rotatably connected to the rotating plate 13, and the other end of the movable seat 12 is symmetrically rotatably connected to a second connecting block 22. A sliding rod 23 is provided between the ends of the two second connecting blocks 22. The bottom of the rotating plate 13 is provided with a sliding groove 24 that is slidably connected to the sliding rod 23. By rotating the second connecting rod on the movable seat 12, the sliding rod 23 at the end of the second connecting rod is driven to make a circular motion. The external force of the sliding rod 23 acting on the sliding groove 24 drives the rotating plate 13 to rotate on the movable seat 12, thereby adjusting the angle between the drill bit 8 and the bulletproof ceramic helmet 2, so that the drill bit 8 is perpendicular to the bulletproof ceramic helmet 2, and avoiding the bulletproof ceramic helmet 2 from shifting during the drilling process, which would affect the drilling quality.

[0033] Preferred, such as Figure 2 and Figure 3As shown, the movable seat 12 is equipped with a second cylinder 25, and the movable end of the second cylinder 25 is equipped with a push block 26. The end of the push block 26 is rotatably connected to a first support rod 27. The other end of the first support rod 27 is rotatably connected to the middle of the second connecting block 22. The second cylinder 25 drives the push block 26 to slide on the movable seat 12, thereby moving one end of the first support rod 27. Since the two ends of the first support rod 27 are rotatably connected to the middle of the push block 26 and the protrusion 18 respectively, the first support rod 27 is driven to rotate on the movable seat 12, thereby driving the fixed seat 7 to rotate on the movable seat 12. This adjusts the angle between the drill bit 8 and the bulletproof ceramic helmet 2, making the drill bit 8 perpendicular to the bulletproof ceramic helmet 2, avoiding the bulletproof ceramic helmet 2 from shifting during the drilling process and affecting the drilling quality. At the same time, the first support rod 27 can share part of the force applied to the second connecting block 22, thereby ensuring the overall stability.

[0034] Preferred, such as Figure 2 , Figure 3 and Figure 4 As shown, the fixed base 7 is provided with a second motor 28, and the movable end of the second motor 28 is provided with a screw 29 that is threadedly connected to the clamping platform 9, thereby driving the clamping platform 9 to slide on the fixed base 7. The fixed base 7 is symmetrically provided with linear slide rails 30, and the bottom of the clamping platform 9 is provided with a second slider 31 that is slidably connected to the linear slide rails 30, which facilitates the sliding of the clamping platform 9 on the fixed base 7 and also serves as a guide.

[0035] Preferred, such as Figure 2 , Figure 3 and Figure 4 As shown, the clamping platform 9 is provided with a bolt 32 and an adjustment hole 33 for the drill bit 8 to pass through. One side of the adjustment hole 33 is open, so that the inner diameter of the adjustment opening can be adjusted to facilitate the passage of the drill bit 8 and to facilitate the adjustment of the position of the drill bit 8 on the clamping platform 9. The clamping platform 9 is provided with a through hole 34 that connects to the adjustment hole 33. After the bolt 32 passes through the through hole 34, it is threaded to the clamping platform 9. By spiraling through the through hole 34 and then threaded to the clamping platform 9, the clamping platform 9 is bent and deformed, reducing the inner diameter of the adjustment hole 33, thereby achieving the purpose of fixing the drill bit 8.

[0036] Preferred, such as Figure 5 and Figure 6As shown, the fixing fixture 3 also includes an upper base 35 that slides vertically and a lower base 36 that slides horizontally. Both the upper base 35 and the lower base 36 are provided with T-slots 37. T-blocks 38 are symmetrically slidably connected within the T-slots 37, such that one end of a corresponding third connecting block 39 is slidably connected to the upper base 35 or the lower base 36 respectively. A third connecting block 39 is rotatably connected to the end of each T-block 38. The other ends of multiple third connecting blocks 39 are rotatably connected to the first fixing block 5 and the second fixing block 6 respectively. A clamping spring 40 is provided between two T-blocks 38. When the bulletproof ceramic helmet 2 is placed on the two first fixing blocks 5, the force acting on the first fixing blocks 5 is transmitted through the two third connecting blocks 39 to the lower T-blocks 38, compressing the clamping spring 40 between the two T-blocks 38. Subsequently, the force moves vertically... The upper base 35 is slidable, causing the two second fixing blocks 6 to contact the outer side of the bulletproof ceramic helmet 2. The reaction force generated after contact is transmitted to the two upper T-shaped blocks 38 through the corresponding third connecting block 39, compressing the clamping spring 40 between the two upper T-shaped blocks 38. Subsequently, the bulletproof ceramic helmet 2 moves vertically downward, further compressing the clamping spring 40 between the two lower T-shaped blocks 38. The rebound force of the clamping spring 40 after compression is reflected to the first fixing block 5 and the second fixing block 6 through the corresponding third connecting block 39, increasing the friction between the first fixing block 5 and the second fixing block 6 and the bulletproof ceramic helmet 2. The upper base 35 continues to move until the overall structure is in a stable state, thereby achieving horizontal, vertical, and longitudinal fixation of the bulletproof ceramic helmet 2 and preventing the bulletproof ceramic helmet 2 from shifting during the drilling process, which would affect the drilling quality.

[0037] Preferred, such as Figure 5 and Figure 6 As shown, the upper base 35 and the lower base 36 are symmetrically rotatably connected with second support rods 41. The ends of the second support rods 41 are rotatably connected to the third connecting block 39, respectively, to bear the force applied to the third connecting block 39 and ensure the stability of the overall structure. The fixing fixture 3 also includes a guide rod 42 slidably connected to the lower base 36 and a guide block 43 slidably connected to the upper base 35, which guide the lower base 36 to slide laterally and the upper base 35 to slide vertically. A third cylinder 44 is provided between the guide block 43 and the upper base 35 to provide power for the lower base 36 to slide vertically.

[0038] Example 1

[0039] This invention provides a production apparatus for bulletproof ceramic helmets, such as... Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the two first fixing blocks 5 and the two second fixing blocks 6 slide symmetrically in the horizontal and vertical directions, respectively; by sliding symmetrically in the horizontal and vertical directions, the ends of the two first fixing blocks 5 and the two second fixing blocks 6 are respectively inserted into the inner and outer sides of the bulletproof ceramic helmet 2, thereby achieving horizontal, vertical, and vertical fixation of the bulletproof ceramic helmet 2 and preventing the bulletproof ceramic helmet 2 from shifting during the drilling process and affecting the drilling quality; the Z-direction position of the drill bit 8 is adjusted by sliding several arc-shaped guide rails 11 on the arc-shaped base frame 10; the movable seat 12 slides on the arc-shaped guide rails 11. 1. Slide the drill bit 8 upwards to adjust its X and Y position. 2. Rotate the rotating plate 13 on the movable seat 12 to adjust the angle between the drill bit 8 and the bulletproof ceramic helmet 2, thereby moving the drill bit to the designated position and vertically aligning it with the bulletproof ceramic helmet 2. This prevents the drill bit 8 from slipping or deviating during the drilling process, which would affect the production quality of the bulletproof ceramic helmet 2. Finally, slide the clamping platform 9 diagonally downwards on the fixed seat 7 to move the drill bit 8 until the end of the drill bit 8 contacts the bulletproof ceramic helmet 2 and gradually penetrates it, thus drilling holes at multiple points on the bulletproof ceramic helmet 2.

[0040] Example 2

[0041] Based on Example 1, such as Figure 1 , Figure 2 ,and Figure 3 As shown, when it is necessary to adjust the position and angle of the drill bit 8, the extension and retraction of the movable end of the first cylinder 15 drives one end of one of the scissor arms 14 to move, so that the two scissor arms 14 open or close to each other, thereby driving the arc guide rail 11 to move on the arc base frame 10 to adjust the Z-direction position of the drill bit 8.

[0042] Next, the first motor 19 drives the drive block 20, which is located at the center of the slide rail, to rotate, causing one end of the corresponding first connecting block 21 to make a circular motion. Since the two ends of the first connecting block 21 are respectively rotatably connected to the drive block 20 and the movable seat 12, the movable seat 12 is driven to slide symmetrically on the arc-shaped guide rail 11, so that the two hole positions are symmetrical about the center of the slide rail, and the X and Y direction positions of the drill bit 8 are adjusted.

[0043] Finally, the second cylinder 25 drives the push block 26 to slide on the movable seat 12, causing one end of the first support rod 27 to move. Since the two ends of the first support rod 27 are rotatably connected to the middle of the push block 26 and the protrusion 18 respectively, the first support rod 27 is driven to rotate on the movable seat 12, causing the slide rod 23 at the end of the second connecting rod to make circular motion. Through the external force of the slide rod 23 acting on the slide groove 24, the rotating plate 13 is driven to rotate on the movable seat 12, thereby adjusting the angle between the drill bit 8 and the bulletproof ceramic helmet 2, so that the drill bit 8 moves to the designated position and is perpendicular to the bulletproof ceramic helmet 2, avoiding the bulletproof ceramic helmet 2 from shifting during the drilling process and affecting the drilling quality. In addition, the first support rod 27 can share part of the force applied to the second connecting block 22, thereby ensuring the overall stability.

[0044] Example 3

[0045] Based on Example 1, such as Figure 2 , Figure 3 and Figure 4 As shown, first loosen the bolt 32 set on the clamp 9 so that the clamp 9 returns to a round shape, enlarge the inner diameter of the adjustment port, so that the drill bit 8 can pass through. After adjusting the position of the drill bit 8 on the clamp 9, it passes through the through hole 34 by spiral and is threaded to the clamp 9, so that the clamp 9 bends and deforms, reducing the inner diameter of the adjustment hole 33, thereby achieving the purpose of fixing the drill bit 8.

[0046] During drilling, the second motor 28 drives the screw 29 to rotate on the fixed seat 7, and the screw 29 is threadedly connected to the clamp 9, thereby driving the clamp 9 to slide on the fixed seat 7, so that the drill bit 8 extends out and contacts the bulletproof ceramic helmet 2, and gradually drills a hole in the corresponding position of the bulletproof ceramic helmet 2; in addition, the sliding connection between the linear slide rail 30 and the second slider 31 facilitates the sliding of the clamp 9 on the fixed seat 7, and at the same time serves as a guide.

[0047] Example 4

[0048] Based on Example 1, such as Figure 5 and Figure 6As shown, when it is necessary to fix the bulletproof ceramic helmet 2, the bulletproof ceramic helmet 2 is placed on two first fixing blocks 5. The force acting on the first fixing blocks 5 is transmitted through two third connecting blocks 39 to the lower T-shaped blocks 38, compressing the clamping spring 40 between the two T-shaped blocks 38. Then, the upper base 35 is driven to slide vertically downward by the second cylinder 25, so that the two second fixing blocks 6 contact the outer side of the bulletproof ceramic helmet 2. The reaction force generated after contact is transmitted through the corresponding third connecting blocks 39 to the two upper T-shaped blocks 38, compressing the clamping spring 40 between the two upper T-shaped blocks 38. Then, the bulletproof ceramic helmet 2 moves vertically downward, further compressing the clamping spring 40 between the two lower T-shaped blocks 38. Some clamping springs 40, after being compressed, have a rebound force that reacts to the first fixing block 5 and the second fixing block 6 through the corresponding third connecting block 39, increasing the friction between the first fixing block 5 and the second fixing block 6 and the bulletproof ceramic helmet 2. The upper base 35 continues to move until the overall structure is in a stable state, thereby achieving horizontal, vertical, and longitudinal fixation of the bulletproof ceramic helmet 2 and preventing the bulletproof ceramic helmet 2 from shifting during the drilling process, which would affect the drilling quality. The upper base 35 and the lower base 36 are symmetrically rotatably connected to the second support rods 41, and the ends of the second support rods 41 are rotatably connected to the third connecting block 39, thereby bearing part of the force applied to the third connecting block 39 and ensuring the stability of the overall structure.
