DETAILED DESCRIPTION

[0023] The present invention provides a movable joint device. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0024] See also Figure 1 and Figure 4 The present invention provides a movable mating device, including a base frame 1, a mating drive mechanism 2 arranged on the base frame 1, a feeding seat 3 and a swinging drive mechanism 4; the feeding seat 3 is set in two, the swinging drive mechanism 4 is arranged on the corresponding feeding seat 3, the swinging drive mechanism 4 is connected to the corresponding sheet metal automatic positioning device 200, and the swinging drive mechanism 4 is used to drive the corresponding sheet metal automatic positioning device 200 to tilt downward or reset upward; the mating drive mechanism 2 is used to drive the two feeding seats 3 to approach or move away from each other.

[0025] See also Figure 4 In actual use, it includes a front feeding device 100, a movable mating device, and a rear dragging device 400 from front to back. The swing driving mechanism 4 located in the front of the movable mating device is connected to the automatic plate positioning device 200, and the swing driving mechanism 4 located in the rear is connected to another automatic plate positioning device 200. A plate cutting and welding mechanism 300 is arranged above the two automatic plate positioning devices 200.

[0026] When two sheets of equal thickness and thickness > 1.0 mm are spliced ​​and welded, the rear drag device 400 conveys the first sheet from the back to the front until the sensor assembly on the front feeding device 100 is triggered, and then the rear drag device 400 conveys the first sheet from the front to the back, and after conveying a certain distance, the sheet automatic positioning device 200 located at the rear clamps the first sheet, and then the sheet cutting and welding mechanism 300 cuts off the edge of the first sheet, and the front feeding device 100 conveys the second sheet from the front to the back, and after conveying a certain distance, the sheet automatic positioning device 200 located at the front clamps the second sheet, and then the sheet cutting and welding mechanism 300 cuts off the edge of the second sheet, and the coupling drive mechanism 2 runs to drive the two feeding seats 3 to approach each other, so that the two sheet automatic positioning devices 200 arranged on the feeding seats 3 approach each other until the head of the second sheet contacts the tail of the first sheet, and then the sheet cutting and welding mechanism 300 welds the contact position.

[0027] Two sheets of equal thickness and less than 1.0 mm or two sheets of unequal thickness and less than 1.0 mm are stacked and welded. The stacking welding is divided into front stacking (i.e., the second sheet is stacked on top of the first sheet) and rear stacking (i.e., the second sheet is stacked on the bottom of the first sheet). The rear stacking is used as an example for description here. The actions of the two sheets before welding are the same as those of splicing welding. Before the first sheet and the second sheet are matched after cutting, the swing drive mechanism 4 located in the front rises and lifts up the automatic sheet positioning device 200 connected thereto, so that the automatic sheet positioning device 200 is tilted downward at a certain angle toward the side of the other automatic sheet positioning device 200. At this time, the automatic sheet positioning device 200 located in the front is in an open state (the two automatic sheet positioning devices 200 are provided with auxiliary material fixing devices, so the auxiliary material fixing is performed when the automatic sheet positioning device 200 is in an open state). The device runs to clamp the corresponding sheet materials); then the matching drive mechanism 2 runs to make the two feeding seats 3 (two automatic sheet material positioning devices 200) approach each other, and the automatic sheet material positioning device 200 located at the rear feeds the first sheet material into the automatic sheet material positioning device 200 located at the front, and then the swing drive mechanism 4 located at the front descends, driving the automatic sheet material positioning device 200 located in the front connected thereto to reset upward (that is, the automatic sheet material positioning device 200 is in a horizontal state again), and then the automatic sheet material positioning device 200 located in the front runs to clamp the two sheets of material at the same time (tooth plates are provided at the upper and lower parts of the automatic sheet material positioning device 200, and the clamping is performed by the tooth plates provided above and below, and then spot welding is performed between the teeth of the tooth plates during welding), and then the sheet material cutting and welding mechanism 300 runs to weld the two sheets of material by spot welding.

[0028] The operation mode of the front stacking is similar to that of the rear stacking, except that the swing driving mechanism 4 at the rear rises, lifts up the automatic sheet positioning device 200 connected to it, and makes the automatic sheet positioning device 200 at the rear tilt downward at a certain angle, and then the second sheet is stacked on top of the first sheet, and the swing driving mechanism 4 at the rear descends, so that the automatic sheet positioning device 200 at the rear is reset upward, and then the automatic sheet positioning device 200 at the rear clamps the two sheets at the same time.

[0029] By setting up a mating drive mechanism 2, the two feeding seats 3 are made to approach each other or move away from each other, thereby realizing the splicing and welding of two sheets; by setting up a swinging drive mechanism 4 on the feeding seat 3, the automatic sheet positioning device 200 connected thereto is tilted downward when the swinging drive mechanism 4 is in operation, so as to facilitate misalignment with another automatic sheet positioning device 200, and under the action of the mating drive mechanism 2, the two sheets are stacked up and down, and the movable mating device cooperates with the automatic sheet positioning device 200 and the sheet cutting and welding mechanism 300 to realize the stacking and welding of the two sheets; the above structure has a small volume, and has both splicing welding, front stacking and back stacking welding methods, and is highly practical.

[0030] See also Figure 1 and Figure 2 Further, the swing drive mechanism 4 includes a swing hydraulic cylinder 41 with an output end facing upward, a swing drive mechanism mounting seat 42 and a swing top block 43; the swing drive mechanism mounting seat 42 is arranged on the side wall of the feeding seat 3 away from the other feeding seat 3, the swing hydraulic cylinder 41 is arranged on the swing drive mechanism mounting seat 42, the output end of the swing hydraulic cylinder 41 is rotatably connected with the swing top block 43, and the upper surface of the swing top block 43 is connected with the lower surface of the sheet metal automatic positioning device 200. The swing hydraulic cylinder 41 has a strong load-bearing capacity relative to the cylinder. In actual use, the swing top block 43 is driven to rise by the extension of the output end of the swing hydraulic cylinder 41, and the swing top block 43 lifts the bottom of the corresponding sheet metal automatic positioning device 200, so that the sheet metal automatic positioning device 200 is tilted downward toward one side of the other sheet metal automatic positioning device 200 (that is, the rear side of the sheet metal automatic positioning device 200 located in the front is tilted downward, and the front side of the sheet metal automatic positioning device 200 located in the rear is tilted downward). On the contrary, the swing top block 43 is driven down and the sheet material automatic positioning device 200 is reset upward by contraction of the output end of the swing hydraulic cylinder 41, and then the sheet material automatic positioning device 200 clamps two sheets at the same time. The above structure is simple, and the swing driving mechanism 4 cooperates with the sheet material automatic positioning device 200 to provide space for stacking sheets.

[0031] See also Figure 1 and Figure 2Furthermore, a swing support seat 5 is provided at both ends of each of the feeding seats 3. The upper surface of the swing support seat 5 is connected to the lower surface of the corresponding sheet metal automatic positioning device 200. Each of the swing support seats 5 rotates when the corresponding sheet metal automatic positioning device 200 tilts downward, and rotates in the opposite direction when the corresponding sheet metal automatic positioning device 200 resets upward. The swing support seat 5 is used to support the two sides of the bottom of the corresponding sheet metal automatic positioning device 200 to play a balancing role. The swing support seat 5 rotates relative to the movement of the sheet metal automatic positioning device 200 to prevent interference.

[0032] See also Figure 1 and Figure 2 Furthermore, the swing support seat 5 includes a supporting bracket 51, a swing frame 52, a swing shaft 53 and a top plate 54; the supporting bracket 51 is arranged on the upper surface of the corresponding feeding seat 3, the swing frame 52 is arranged inside the supporting bracket 51, and the two ends of the swing shaft 53 pass through the left and right sides of the supporting bracket 51 and the swing frame 52, and the top plate 54 is arranged on the upper surface of the swing frame 52, and the upper surface of the top plate 54 is connected to the lower surface of the automatic sheet positioning device 200. In actual use, the top plate 54 is used to support the corresponding automatic sheet metal positioning device 200. When the swing hydraulic cylinder 41 rises, the corresponding automatic sheet metal positioning device 200 tilts downward, driving the swing frame 52 and the top plate 54 to rotate around the swing axis 53, so that the swing frame 52 and the top plate 54 rotate toward the direction of the other automatic sheet metal positioning device 200; when the swing hydraulic cylinder 41 descends, the corresponding automatic sheet metal positioning device 200 resets upward, driving the swing frame 52 and the top plate 54 to rotate in the direction away from the other automatic sheet metal positioning device 200 (i.e., reverse rotation), so that the corresponding automatic sheet metal positioning device 200 is in a horizontal state again.

[0033] See also Figure 2 Further, the supporting bracket 51 includes two first support plates 511 and a second support plate 512 connecting the two ends of the two first support plates 511; the upper parts of the two first support plates 511 are both provided with chamfers, and the height of the second support plate 512 is less than the height of the first support plate 511; the swing frame 52 includes two third support plates 521 and a fourth support plate 522 arranged between the two third support plates 521; the lower parts of the two third support plates 521 are both provided with chamfers, and the inclination angle of the chamfer on the third support plate 521 is greater than the inclination angle of the chamfer on the first support plate 511. By respectively providing chamfers on the upper part of the first support plate 511 and the lower part of the third support plate 521 and limiting the height of the second support plate 512, space is provided for the rotation of the third support plate 521 when the sheet material automatic positioning device 200 tilts downward or resets upward.

[0034] See also Figure 1 and Figure 2 Furthermore, an angle adjustment mechanism 6 is provided on the inner side wall of the supporting bracket 51, and the angle adjustment mechanism 6 includes two angle adjustment seats 61 and two screw rods 62; the two angle adjustment seats 61 are respectively provided along the front and rear directions of the base frame 1, and each of the angle adjustment seats 61 is provided with a threaded hole, and the screw rod 62 is threadedly connected with the corresponding threaded hole. In actual use, by adjusting the height of the two screw rods 62 relative to the angle adjustment seat 61, the swing angle of the corresponding sheet metal automatic positioning device 200 is adjusted, and the working process of the angle adjustment mechanism 6 is described by taking the angle adjustment mechanism 6 located in the front as an example. The screw rod 62 near another sheet metal automatic positioning device 200 is screwed into the angle adjustment seat 61, so that the length of the screw rod 62 protruding from the angle adjustment seat 61 becomes shorter. When the sheet metal automatic positioning device 200 located in the front tilts downward, the protruding length of the screw rod 62 becomes shorter, so that the angle of the sheet metal automatic positioning device 200 tilting downward becomes larger; conversely, when the length of the screw rod 62 protruding from the angle adjustment seat 61 becomes longer, the angle of the sheet metal automatic positioning device 200 tilting downward becomes smaller. Similarly, when the screw rod 62 far from another sheet metal automatic positioning device 200 is screwed into the angle adjustment seat 61, the length of the screw rod 62 protruding from the angle adjustment seat 61 becomes shorter. When the sheet metal automatic positioning device 200 located in the front is reset upward, its tilt angle becomes larger. It should be noted here that when the length of the screw rod 62 protruding from the angle adjustment seat 61 away from the other sheet metal automatic positioning device 200 is too short, it is easy for the sheet metal automatic positioning device 200 located in the front to tilt upward at a certain angle, and it is easy to bend the first sheet metal (i.e., the rear sheet metal) when clamping the two sheets; and when the length of the screw rod 62 protruding from the angle adjustment seat 61 is too long, it is easy for the sheet metal automatic positioning device 200 to still tilt downward after resetting, and after clamping the two sheets, it affects the sheet metal cutting and welding mechanism 300 to weld the sheets. Therefore, through the above-mentioned setting, on the one hand, it plays a role in supporting and limiting the sheet metal automatic positioning device 200 when it tilts downward and resets upward, and on the other hand, it is convenient to fine-tune the angle of the sheet metal automatic positioning device 200 according to actual use conditions, so that the position of the sheet metal inserted into the sheet metal automatic positioning device 200 is optimal and the welding position is optimal.

[0035] See also Figure 2Further, two vertical grooves 513 are provided on the inner side wall of the supporting bracket 51, and convex strips 611 are provided on the outer side walls of the two angle adjustment seats 61. The convex strips 611 are provided in the corresponding grooves 513. The supporting bracket 51 and the angle adjustment seat 61 are provided with mounting holes 612, and the same connecting piece is provided in the two mounting holes 612. When installing the angle adjustment seat 61, the convex strips 611 are inserted into the grooves 513 along the height direction of the grooves, and then the angle adjustment seat 61 is fixed to the supporting bracket 51 through the connecting piece. Specifically, the connecting piece can be set as a bolt and a nut threadedly connected to the bolt.

[0036] See also Figure 1 and Figure 3 Furthermore, the mating drive mechanism 2 includes a mating drive motor 21, a first coupling 22, a first lead screw 23, a second coupling 24 and a second lead screw 25 connected in sequence; the output end of the mating drive motor 21 extends along the length direction of the base frame 1; a first nut seat 26 is provided on the first lead screw 23, and the upper surface of the first nut seat 26 is connected to the lower surface of one of the feeding seats 3 (the feeding seat 3 located in the front in this embodiment), and a second nut seat 27 is provided on the second lead screw 25, and the upper surface of the second nut seat 27 is connected to the lower surface of another feeding seat 3 (the feeding seat 3 located in the rear in this embodiment), and the thread on the first lead screw 23 is opposite to the thread on the second lead screw 25. In this embodiment, when the mating drive motor 21 rotates forward, it drives the first coupling 22, the first screw 23, the second coupling 24 and the second screw 25 to rotate forward. Since the threads on the first screw 23 and the threads on the second screw 25 are arranged in opposite directions, the first nut seat 26 and the second nut seat 27 are brought close to each other and the two feeding seats 3 are brought close to each other; when the mating drive motor 21 rotates reversely, it drives the first coupling 22, the first screw 23, the second coupling 24 and the second screw 25 to rotate reversely, and the first nut seat 26 and the second nut seat 27 are brought close to each other and the two feeding seats 3 are moved away from each other. Through the above arrangement, the two feeding seats 3 move simultaneously and share the same mating drive mechanism 2, with high synchronization, which is conducive to the precise mating of the feeding seats 3.

[0037] See also Figure 2Furthermore, the upper surface of the base frame 1 is provided with a matching guide rail 11 along its length direction, and the matching guide rail 11 is provided with two or more matching sliders 12 matched therewith, and the upper surface of the matching slider 12 is connected to the corresponding lower surface of the feeding seat 3. The middle parts of the two feeding seats 3 are respectively connected to the first nut seat 26 and the second nut seat 27. By providing the matching slider 12, the two ends of the two feeding seats 3 are respectively connected to the corresponding matching slider 12, and the matching slider 12 cooperates with the matching guide rail 11, so that the two feeding seats 3 move smoothly.

[0038] See also Figure 1 and Figure 3 Furthermore, a balancing cylinder 14 is also provided on the inner side wall of the base frame 1, and the output end of the balancing cylinder 14 extends along the length direction of the base frame 1, and the output end is connected to the lower surface of the corresponding feeding seat 3. In actual use, when the two feeding seats 3 are close to each other, the output ends of the two groups of balancing cylinders 14 arranged opposite to each other are synchronously extended; when the two feeding seats 3 are away from each other, the output ends of the two groups of balancing cylinders 14 arranged opposite to each other are synchronously contracted. By providing the balancing cylinder 14, it is used to prevent the automatic plate positioning device 200 connected to the feeding seat 3 from starting and stopping when the feeding seats 3 are aligned.

[0039] See also Figure 1 and Figure 3 Furthermore, a sensing block 31 is provided on the side wall of any one of the feeding seats 3, and a position sensing component 13 for sensing the sensing block 31 is provided on the side wall of the base frame 1, and the position sensing component 13 includes a first position sensor 131, a zero position sensor 132 and a second position sensor 133, and the distance between the first position sensor 131 and the second position sensor 133 is the maximum moving stroke of the two feeding seats 3. When the zero position sensor 132 senses the sensing block 31, the zero position sensor 132 transmits a signal to the control mechanism, and the control mechanism transmits a signal to the mating drive motor 21 to control the mating drive motor 21 to stop running, at which time the two feeding seats 3 move away from each other; similarly, when the second position sensor 133 senses the sensing block 31, the second position sensor 133 transmits a signal to the control mechanism, and the control mechanism transmits a signal to the mating drive motor 21 to control the mating drive motor 21 to stop running, at which time the two feeding seats 3 move closer to each other; the first position sensor 131 is provided to protect the feeding seat 3, and when the zero position sensor 132 fails, the mating drive mechanism 2 continues to run, and when the first position sensor 131 senses the sensing block 31, the mating drive motor 21 is also stopped by signal transmission. Through the above arrangement, the linkage of the components in the movable mating device is higher, which is conducive to improving its automation.

[0040] In summary, the present invention realizes the splicing and welding of two sheets by setting a matching drive mechanism 2 to make the two feeding seats 3 approach or move away from each other; by setting a swing drive mechanism 4 on the feeding seat 3, the sheet automatic positioning device 200 connected thereto is tilted downward when the swing drive mechanism 4 is in operation, so as to facilitate misalignment with another sheet automatic positioning device 200, and under the action of the matching drive mechanism 2, the two sheets are stacked up and down, and the movable matching device cooperates with the sheet automatic positioning device 200 and the sheet cutting and welding mechanism 300 to realize the stacking and welding of the two sheets; the above structure is small in size and has the advantages of splicing welding, front stacking and back stacking, and is highly practical. By setting a swing drive mechanism 4, the sheet automatic positioning device 200 is tilted downward or reset upward by extending or contracting the output end of the swing hydraulic cylinder 41.

By setting the swing frame 52 and the top plate 54, the swing frame 52 and the top plate 54 are rotated relative to the movement of the sheet material automatic positioning device 200, which plays a role in assisting the movement of the sheet material automatic positioning device 200. By setting chamfers on the upper part of the first support plate 511 and the lower part of the third support plate 521 and limiting the height of the second support plate 512, the swing frame 52 provides space for the rotation of the third support plate 521 when it needs to rotate. By setting the angle adjustment mechanism 6, the swing angle of the sheet material automatic positioning device 200 is adjusted. By setting the groove 513 and the convex strip 611, a mounting surface is provided for the angle adjustment seat 61. By setting the matching drive motor 21, the lead screw and the nut seat, the two feeding seats 3 are moved closer to each other or away from each other. By setting the matching guide rail 11 and the matching slide block 12, the movement stability of the two feeding seats 3 is improved. By setting the position sensing component 13 and the sensing block 31, the linkage and automation of each component in the movable matching device are improved.
