Description

Technical Field

[0001] This invention relates to the field of automated welding technology, specifically to an automated welding device suitable for the processing of security doors. Background Technology

[0002] Security doors are widely used in our lives, serving to prevent theft and provide protection. In the production of security doors, welding is one of the most important processes. The high current and high voltage of the welding machine generate heat that is concentrated at the end of the welding gun, melting the welding wire. The molten welding wire penetrates into the part to be welded. After cooling, the welded objects are firmly connected into one, thus connecting the various structural components of the security door together.

[0003] Chinese patent [CN217513128U] discloses a security door welding machine that can achieve uniform heating. By preheating the security door before welding and ensuring uniform heating, more heat is retained inside the door, reducing the amount of heat required during welding and shortening the welding time. After welding, the surface of the security door is rinsed with water to remove impurities and cool it down. However, this patent still has the following drawbacks in practical application: Firstly, when the aforementioned patent is used for welding, the welding head contacts the door body to perform welding. During the welding process, metal objects are prone to splashing, and if the metal objects splash onto other equipment, they can easily cause damage to other equipment and affect the service life of the equipment. Secondly, the aforementioned patent involves placing the security door on a base for subsequent welding operations. However, the placement of the security door is difficult to determine. When welding multiple security doors, it is difficult to maintain the same placement position. Therefore, during the welding operation, the welding position is prone to shift, affecting the welding quality.

[0004] Therefore, an automated welding device suitable for the processing of security doors is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention discloses an automated welding device suitable for the processing of security doors, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated welding device suitable for the processing of security doors, comprising: A workbench, the top of which is equipped with a lifting mechanism, and the lifting mechanism is equipped with a moving mechanism. A connecting box is installed at the left end of the moving mechanism, and a welding mechanism is installed on the connecting box. The main body of the security door is placed on the surface of the workbench; A connecting column is fixedly installed at the bottom of the connecting box, and the bottom of the welding mechanism extends downward through the connecting column. A protective component is provided on the outer wall of the connecting column, and the protective component covers the outside of the welding mechanism to prevent metal from splashing during the welding process. The protective assembly includes a protective cover, a connecting cylinder, and a connecting sleeve. The connecting cylinder is fixedly welded to the upper end of the protective cover and sleeved on the outer wall of the connecting column. The bottom of the protective cover has a groove, and the top of the connecting sleeve is movably inserted into the groove at the bottom of the protective cover. The top of the workbench is equipped with a limiting component, which acts on both sides of the anti-theft door body to restrict the position of the anti-theft door body.

[0007] Preferably, the limiting component includes a setting box, an adjusting column, a first limiting block, and a second limiting block. The setting box is fixedly installed on the top of the workbench, and the bottom of the adjusting column is rotatably connected to the bottom of the inner cavity of the setting box via a bearing. A transmission gear is fixedly installed on the outer wall of the adjusting column. A first rack block is meshed with the right side of the transmission gear. A sliding block is fixedly installed on the left end of the first rack block and is fixedly connected to the first limiting block. A second rack block is meshed with the left side of the transmission gear and is fixedly connected to the second limiting block. The right end of the anti-theft door body is inserted between the first limiting block and the second limiting block.

[0008] Preferably, the top of the adjusting column extends upward through the setting box, a rotating disk is fixedly installed on the outer wall of the adjusting column, and a fixing hole is opened on the outer wall of the rotating disk. A fixing block is fixedly installed on the top of the setting box, and a fixing rod is threadedly connected to the rear end of the fixing block, and the front end of the fixing rod is inserted into the corresponding fixing hole.

[0009] Preferably, the left side of the setting box has a sliding groove, and the sliding block is slidably engaged in the sliding groove.

[0010] Preferably, an installation block is fixedly installed on the outer wall of the connecting column, the bottom of the installation block has an insertion port, and the top of the connecting cylinder extends upward through the insertion port. The outer wall of the connecting cylinder has a slot, a card block is inserted into the installation block, and the outer wall of the connecting column has a slot, with the rear end of the card block passing through the slot and engaging in the slot.

[0011] Preferably, a second spring strip is fixedly provided on the front wall of the inner cavity of the mounting block, and a push plate is fixedly installed on the rear end of the second spring strip. The push plate is fixedly installed on the outer wall of the block, and an adjustment plate is fixedly installed on the front end of the block.

[0012] Preferably, a limiting groove is formed at the bottom of the mounting block, a limiting ball is fixedly installed on the outer wall of the connecting cylinder and the limiting ball is engaged in the limiting groove, and a protective cover is installed at the bottom of the connecting cylinder.

This facilitates the installation of the protective cover on the connecting column and provides shielding around the welding mechanism, improving the sealing of the surrounding environment during welding operations and preventing metal spatter. This design prevents metal objects from flying, reduces damage to other equipment, and extends the lifespan of the device. Furthermore, by establishing the connection between the setting box, adjusting column, first limit block, second limit block, and the main body of the security door, the main body of the security door can be placed between the first and second limit blocks. Rotating the adjusting column moves the first and second limit blocks towards the center, pushing the main body of the security door towards the center position. This facilitates positioning the main body of the security door in the center of the setting box, allowing for precise positioning and ensuring that all security doors are placed in the same position for welding operations, thus improving welding efficiency.

[0016] 2. This automated welding device for processing security doors is configured by setting up a connection relationship between an installation block, a second spring strip, a push plate, a locking block, and a connecting cylinder. The second spring strip is fixedly installed on the front wall of the inner cavity of the installation block, and a push plate is fixedly installed at the rear end of the second spring strip. The push plate is fixedly installed on the outer wall of the locking block to push the locking block inward, which facilitates the restriction of the position of the connecting cylinder. An adjustment plate is fixedly installed at the front end of the locking block. The adjustment plate is provided with a groove, which makes it convenient for the user to pull the locking block outward, so as to facilitate the removal of the connecting cylinder from the outer wall of the connecting column.

[0017] 3. This automated welding device for processing security doors, through the connection relationship between the limiting groove and the limiting ball, the limiting groove is opened at the bottom of the mounting block, the limiting ball is fixedly installed on the outer wall of the connecting cylinder, and the limiting ball is locked in the limiting groove. A protective cover is installed at the bottom of the connecting cylinder to position the installation position of the connecting cylinder, so that the slot and the block are aligned.

Detailed Implementation

[0020] Example 1

[0021] This invention discloses an automated welding device suitable for the processing of security doors, such as... Figure 1-8 As shown, it includes: like Figure 1-8 The figure shows an automated welding device suitable for the processing of security doors, comprising: The workbench 1 has a lifting mechanism 2 on its top and a moving mechanism 201 on its lifting mechanism 2. A connecting box 202 is installed on the left end of the moving mechanism 201 and a welding mechanism 204 is installed on the connecting box 202. The structure of the workbench 1, lifting mechanism 2, moving mechanism 201 and welding mechanism 204 is already in Chinese patent [CN217513128U], so it will not be described in this invention. The main body of the security door 3 is placed on the upper surface of the workbench 1; A connecting column 203 is fixedly installed at the bottom of the connecting box 202, and the bottom of the welding mechanism 204 extends downward through the connecting column 203. A protective component is provided on the outer wall of the connecting column 203. The protective component covers the periphery of the welding mechanism 204 to prevent metal from splashing during the welding process. The protective assembly includes a protective cover 4, a connecting cylinder 401, and a connecting cover 406. The connecting cylinder 401 is fixedly welded to the upper end of the protective cover 4 and sleeved on the outer wall of the connecting column 203. The bottom of the protective cover 4 has a groove, and the top of the connecting cover 406 is movably inserted into the groove at the bottom of the protective cover 4. The protective cover 4 is sleeved on the outer wall of the welding mechanism 204 and plays a protective and shielding role during the welding operation of the welding mechanism 204.

[0022] Preferably, the length of the moving groove (404) is greater than the length of the moving block (405) to limit the extension and retraction stroke of the connecting cover (406) relative to the protective cover (4), ensuring that during the welding process, the connecting cover (406) contacts the anti-theft door body (3) before the end of the welding mechanism (204) and is compressed back into the protective cover (4) as the welding mechanism (204) continues to descend.

[0023] The top of the workbench 1 is equipped with a limiting component, which acts on both sides of the anti-theft door body 3 to limit the position of the anti-theft door body 3.

[0024] According to the appendix Figure 6 As shown, a first spring strip 407 is fixedly installed on the top of the inner cavity of the protective cover 4, and the other end of the first spring strip 407 is fixedly installed on the connecting cover 406 for pushing the connecting cover 406 downward, so as to make the bottom of the connecting cover 406 fit with the anti-theft door body 3, thereby improving the sealing performance.

[0025] According to the appendix Figure 6 As shown, a movable groove 404 is provided on the inner wall of the inner cavity of the protective cover 4. A movable block 405 is slidably engaged on the inner wall of the movable groove 404. The movable block 405 is fixedly installed on the outer wall of the connecting cover 406 to limit the movement trajectory and direction of the connecting cover 406 and prevent the connecting cover 406 from detaching from the protective cover 4.

[0026] For those skilled in the art, the protective cover 4 and the connecting cylinder 401 shield the outside of the welding mechanism 204 to confine the metal spatter generated during the welding operation within the inner cavity of the protective cover 4, thereby preventing the metal spatter from splashing onto other equipment and thus avoiding damage to other equipment.

[0027] Example 2

[0028] like Figure 1-8 The figure shows an automated welding device suitable for the processing of security doors, comprising: The workbench 1 has a lifting mechanism 2 on its top and a moving mechanism 201 on its lifting mechanism 2. A connecting box 202 is installed on the left end of the moving mechanism 201 and a welding mechanism 204 is installed on the connecting box 202. The structure of the workbench 1, lifting mechanism 2, moving mechanism 201 and welding mechanism 204 is already in Chinese patent [CN217513128U], so it will not be described in this invention. The main body of the security door 3 is placed on the upper surface of the workbench 1; A connecting column 203 is fixedly installed at the bottom of the connecting box 202, and the bottom of the welding mechanism 204 extends downward through the connecting column 203. A protective component is provided on the outer wall of the connecting column 203. The protective component covers the periphery of the welding mechanism 204 to prevent metal from splashing during the welding process. The protective assembly includes a protective cover 4, a connecting cylinder 401, and a connecting cover 406. The connecting cylinder 401 is fixedly welded to the upper end of the protective cover 4 and sleeved on the outer wall of the connecting column 203. Preferably, the connecting cylinder (401) is fixedly connected to the upper end of the protective cover (4), and the connecting cylinder (401) is detachably sleeved on the outer wall of the connecting column (203). The bottom of the protective cover 4 is provided with a groove, and the top of the connecting cover 406 is movably inserted into the groove at the bottom of the protective cover 4. The protective cover 4 is sleeved on the outer wall of the welding mechanism 204, and plays a protective and shielding role during the welding operation of the welding mechanism 204. The top of the workbench 1 is equipped with a limiting component, which acts on both sides of the anti-theft door body 3 to limit the position of the anti-theft door body 3.

[0029] According to the appendix Figure 7 As shown, the limiting assembly includes a setting box 6, an adjusting column 601, a first limiting block 605, and a second limiting block 607. The setting box 6 is fixedly installed on the top of the workbench 1, and the bottom of the adjusting column 601 is rotatably connected to the bottom of the inner cavity of the setting box 6 via a bearing. A transmission gear 602 is fixedly installed on the outer wall of the adjusting column 601. A first rack block 603 is meshed with the right side of the transmission gear 602. A sliding block 604 is fixedly installed on the left end of the first rack block 603, and the sliding block 604 is fixedly connected to the first limiting block 605. A second rack block 606 is meshed with the left side of the transmission gear 602. The second rack block 606 is fixedly connected to the second limiting block 607. The right end of the anti-theft door body 3 is inserted between the first limiting block 605 and the second limiting block 607. This is used to connect the movement states of the first limiting block 605 and the second limiting block 607, so that the first limiting block 605 and the second limiting block 607 can move simultaneously through the rotation of the adjusting column 601. This facilitates user operation and allows control over the distance between the moving positions of the first limiting block 605 and the second limiting block 607, making it easier to move the anti-theft door body 3 to the middle position of the setting box 6, thus facilitating the positioning of the anti-theft door body 3.

[0030] According to the appendix Figure 8 As shown, the top of the adjusting column 601 extends upward through the setting box 6. A rotating disk 608 is fixedly installed on the outer wall of the adjusting column 601, and a fixing hole 609 is provided on the outer wall of the rotating disk 608. Multiple sets of fixing holes 609 are provided to correspond to different restriction positions, so that they can be adjusted according to the width of the anti-theft door body 3. A fixing block 610 is fixedly installed on the top of the setting box 6. A fixing rod 611 is threadedly connected to the rear end of the fixing block 610, and the front end of the fixing rod 611 is inserted into the corresponding fixing hole 609 to fix the position of the rotating disk 608, so as to restrict the adjusting column 601 from continuing to rotate, thereby fixing the first limiting block 605 and the second limiting block 607 in the set position.

[0031] According to the appendix Figure 7 and 8 As shown, a sliding groove 612 is provided on the left side of the set box 6, and the sliding block 604 is slidably engaged in the sliding groove 612, which facilitates limiting the movement trajectory and movement range of the first limit block 605.

[0032] Preferably, the top of the setting box (6) is provided with a guide groove, and the first limiting block (605) and the second limiting block (607) are both slidably engaged in the guide groove.

[0033] For those skilled in the art, by setting the connection relationship between the setting box 6, the adjusting column 601, the first limiting block 605, the second limiting block 607, and the anti-theft door body 3, the anti-theft door body 3 can be placed between the first limiting block 605 and the second limiting block 607. By rotating the adjusting column 601, the first limiting block 605 and the second limiting block 607 can be moved towards the center, thus pushing the anti-theft door body 3 to the center position. This makes it easy to place the anti-theft door body 3 in the center position of the setting box 6, which facilitates the limitation of its position and ensures that each anti-theft door body 3 is placed in the same position for welding operations, thereby improving the welding effect.

[0034] Example 3

[0035] like Figure 1-8 The figure shows an automated welding device suitable for the processing of security doors, comprising: The workbench 1 has a lifting mechanism 2 on its top and a moving mechanism 201 on its lifting mechanism 2. A connecting box 202 is installed on the left end of the moving mechanism 201 and a welding mechanism 204 is installed on the connecting box 202. The structure of the workbench 1, lifting mechanism 2, moving mechanism 201 and welding mechanism 204 is already in Chinese patent [CN217513128U], so it will not be described in this invention. The main body of the security door 3 is placed on the upper surface of the workbench 1; A connecting column 203 is fixedly installed at the bottom of the connecting box 202, and the bottom of the welding mechanism 204 extends downward through the connecting column 203. A protective component is provided on the outer wall of the connecting column 203. The protective component covers the periphery of the welding mechanism 204 to prevent metal from splashing during the welding process. The protective assembly includes a protective cover 4, a connecting cylinder 401, and a connecting cover 406. The connecting cylinder 401 is fixedly welded to the upper end of the protective cover 4 and sleeved on the outer wall of the connecting column 203. The bottom of the protective cover 4 has a groove, and the top of the connecting cover 406 is movably inserted into the groove at the bottom of the protective cover 4. The protective cover 4 is sleeved on the outer wall of the welding mechanism 204 and plays a protective and shielding role during the welding operation of the welding mechanism 204. The top of the workbench 1 is equipped with a limiting component, which acts on both sides of the anti-theft door body 3 to limit the position of the anti-theft door body 3.

[0036] According to the appendix Figure 4 and 5 As shown, an installation block 5 is fixedly installed on the outer wall of the connecting column 203. The bottom of the installation block 5 has an insertion port 501, and the top of the connecting cylinder 401 extends upward through the insertion port 501. The outer wall of the connecting cylinder 401 has a slot 402. A locking block 502 is inserted into the upper part of the installation block 5. The outer wall of the connecting column 203 has a slot 205, and the rear end of the locking block 502 passes through the slot 402 and engages in the slot 205. This is used to limit the connecting cylinder 401 on the outer wall of the connecting column 203, so that the protective cover 4 can be installed on the outer wall of the welding mechanism 204. This facilitates installation, makes it easy to shield the welding mechanism 204, and makes it easy to disassemble, maintain, and replace.

[0037] According to the appendix Figure 4 As shown, a second spring strip 504 is fixedly installed on the front wall of the inner cavity of the mounting block 5, and a push plate 503 is fixedly installed on the rear end of the second spring strip 504. The push plate 503 is fixedly installed on the outer wall of the locking block 502 and is used to push the locking block 502 inward to restrict the position of the connecting cylinder 401. An adjustment plate 505 is fixedly installed on the front end of the locking block 502. A groove is provided on the adjustment plate 505 to facilitate the user to pull the locking block 502 outward and to facilitate the removal of the connecting cylinder 401 from the outer wall of the connecting column 203.

[0038] According to the appendix Figure 3 and 5 As shown, a limiting groove 506 is provided at the bottom of the mounting block 5, and a limiting ball 403 is fixedly installed on the outer wall of the connecting cylinder 401. The limiting ball 403 is engaged in the limiting groove 506. A protective cover 4 is installed at the bottom of the connecting cylinder 401 to position the installation position of the connecting cylinder 401 so that the slot 402 is aligned with the position of the block 502.

[0039] For those skilled in the art, by setting the connection relationship between the protective cover 4, the connecting cylinder 401, the mounting block 5, and the locking block 502, pulling the adjusting plate 505 outward causes the locking block 502 to move outward, allowing the connecting cylinder 401 to be inserted into the socket 501. At this time, by releasing the outward-pulling adjusting plate 505, the second spring bar 504 causes the locking block 502 to move inward, allowing the locking block 502 to pass through the slot 402 and be inserted into the slot 205, making it easy to install the protective cover 4 on the connecting post 203. Furthermore, by pulling the adjusting plate 505 outward, the locking block 502 is moved, causing the locking block 502 to disengage from the slot 402, making it possible to remove the connecting cylinder 401 from the bottom of the mounting block 5, facilitating maintenance, replacement, and convenient use.

[0040] Working principle: The user can pull the adjusting plate 505 outward, causing the adjusting plate 505 to move the locking block 502 outward, so that the locking block 502 moves out of the slot 205 and into the mounting block 5. At this time, the user can put the connecting cylinder 401 on the outer wall of the connecting post 203 and move it upward, so that the connecting post 203 moves into the inner wall of the socket 501 and the limiting ball 403 is locked into the limiting groove 506. At this time, the user can release the adjusting plate 505 pulled outward, so that the pushing force of the second spring bar 504 pushes the push plate 503 inward, so that the push plate 503 moves backward, and the user can release the adjusting plate 505 pulled outward, so that the user can release the adjusting plate 505 outward, so that the user can release the adjusting plate 505 outward, so that the user can release the adjusting plate 502 ... The movable push plate 503 passes through the slot 402 and inserts into the slot 205, allowing the connecting cylinder 401 to be installed on the outer wall of the connecting column 203. By activating the lifting mechanism 2 and the welding mechanism 204, the lifting mechanism 2 drives the welding mechanism 204 to move downwards to perform welding operations on the anti-theft door body 3. This causes the protective cover 4 and the connecting cover 406 to move downwards, and the connecting cover 406 is pushed downwards by the pushing force of the first spring bar 407, making it easier for the bottom of the connecting cover 406 to fit against the surface of the anti-theft door body 3. This improves the sealing performance, helps to block metal objects, and prevents metal objects from flying. Furthermore, by pulling the adjusting plate 505 outward, the locking block 502 is moved, causing the locking block 502 to disengage from the slot 402, so that the connecting cylinder 401 can be removed from the bottom of the mounting block 5, making it convenient for maintenance, replacement, and use.

[0041] The user can place the main body 3 of the security door between the first limiting block 605 and the second limiting block 607. The user can then rotate the adjusting column 601 clockwise, causing it to drive the transmission gear 602 forward. This causes the right side of the rotating transmission gear 602 to press and push the first rack block 603 forward, moving it forward. The forward-moving rack block 603 then drives the sliding block 604 forward, which in turn moves the first limiting block 605 forward. The forward-moving first limiting block 605 pushes the front wall of the security door body 3. Simultaneously, the clockwise rotating transmission gear 602 presses and pushes the second rack block 606 from the left, causing the second rack block 606 to move backward. This backward movement of the second rack block 606 drives the second limiting block 607 to move backward, which in turn pushes the security door body 3 backward. This facilitates the placement of the security door body 3 in the middle of the mounting box 6, making it easier to position and preventing misalignment between the various security doors 3, thus improving the welding effect. After setting the first limiting block 605 and the second limiting block 607, the user can stop rotating the adjusting column 601 to stop the rotating disk 608. At this time, by rotating the fixing rod 611 clockwise to the right, the fixing rod 611 moves forward along the thread direction of the inner wall of the fixing block 610, so that the front end of the fixing rod 611 is inserted into the corresponding fixing hole 609, which facilitates limiting the rotation of the adjusting column 601 and fixing the positions of the first limiting block 605 and the second limiting block 607. This makes it easier to restrict the position of the security door 3. Furthermore, by clamping the security door 3 between the first limiting block 605 and the second limiting block 607, the position of the security door 3 is fixed, preventing the security door 3 from shifting during the welding process and making it convenient to use.
