Description

Technical Field

[0001] The present application relates to the technical field of building formwork welding, and in particular to a building formwork welding sealing device. Background Art

[0002] Building formwork generally refers to a reusable sheet material used in concrete structure construction. It is used to form the surface shape of concrete structures, such as beams, columns, walls, etc. Building formwork needs to be designed before use to ensure that its size, shape and structural strength meet the requirements of the project. The quality and installation of the formwork have an important impact on the accuracy and construction efficiency of the structure.

[0003] In the prior art, some building templates are usually composed of a U-shaped material and two side sealing plates. During the processing, the two side sealing plates need to be welded to the openings at both ends of the U-shaped material to finally form a complete frame structure. In the subsequent construction process, multiple building templates must first be surrounded into a suitable shape according to construction requirements, and then cement is poured into the interior of the frame structure from the opening and wait for it to be formed to complete the initial construction of the building.

[0004] Referring to the Chinese patent application document with publication number CN118180765A and publication date June 14, 2024, entitled "A building formwork welding sealing device", the automatic loading, positioning and welding of building formwork parts can be achieved through the cooperation of a loading robot, a positioning assembly and a welding robot arm.

[0005] According to the above technical solution, when welding the two side sealing plates to the openings at both ends of the U-profile, it is necessary to first place the side sealing plates in the openings at both ends of the U-profile, and at the same time ensure that the relative outer sides of the two side sealing plates are flush with the end faces on both sides of the U-profile. In this case, after the U-profile is moved to the welding station, in order to solve the problem of uncertain feeding position and displacement of the side sealing plates during welding that affects welding accuracy, it is often necessary to calibrate and position the side sealing plates with the help of the feeding robot and the positioning assembly before subsequent welding work can be carried out. However, at this time, due to the cumbersome operation steps, it is easy to affect the overall efficiency of the welding work to a certain extent. Summary of the invention

[0006] In view of this, the present application provides a building formwork welding sealing plate device, which is mainly used to solve the problem that the operation steps of the welding work are relatively cumbersome and easily affect the welding efficiency under the welding process limitations of the U-profile and the side sealing plate.

[0007] In order to solve the above-mentioned technical problems, the present application provides a building formwork welding sealing plate device, comprising a welding table and a transfer vehicle for carrying U-profiles, and two welding robotic arms are symmetrically arranged on the welding table; two linear drivers are symmetrically arranged on the welding table, and the execution ends of the linear drivers are provided with limit blocks for driving the lateral displacement of the U-profile; two groups of horizontally arranged loading columns are symmetrically arranged on the welding table, and the loading columns are matched with the through holes on the side sealing plates, each group of loading columns is connected to a push plate through a first spring for transverse sliding, and a damping spring pin is provided at the unloading end of the loading column, and when the limit block moves to the extreme position away from the center of the welding table driven by the linear driver, the distance between the limit block and the corresponding damping spring pin is consistent with the thickness of the side sealing plate.

[0008] By adopting the above technical scheme, the two limit shift blocks cooperate with each other, which can drive the U-profile to move and serve as the movement limit of the U-profile at the same time, so that the U-profile can be accurately aligned with the side sealing plate after arriving at the welding station, thereby eliminating the calibration step to improve the efficiency of the overall welding work; through the cooperation of the first spring and the damping spring pin, the loading position of each side sealing plate can be kept consistent while realizing automatic loading, so that the U-profile and the side sealing plate can be accurately in place to avoid positional offset between the two and affect the welding accuracy. At the same time, the welding work of the U-profile and the side sealing plate can be carried out continuously to meet the welding needs of large quantities of U-profiles and side sealing plates.

[0009] Optionally, the limit shift block is provided with an adjusting bolt for adjusting the distance between the limit shift block and the damping spring pin corresponding thereto when the limit shift block moves to an extreme position away from the center of the welding table.

[0010] By adopting the above technical solution, personnel can manually turn the adjusting bolt to change the limit position of the limit block when it moves, and then when the limit block moves to the limit position away from the center of the welding table, the distance between the limit block and the damping spring pin changes, so as to be suitable for welding side sealing plates of different thicknesses.

[0011] Optionally, two movable frames capable of being abutted by the U-profile are symmetrically arranged on the welding table in a transverse sliding connection via a second spring, and a locking member is arranged between the movable frame and the pushing plate for locking the position of the pushing plate when the movable frame is away from the center of the welding table.

[0012] By adopting the above technical solution, when the U-profile approaches the side sealing plate, the U-profile will abut against the moving frame and drive the moving frame away from the center of the welding table. At this time, through the cooperation of the locking part, the position of the pushing plate will be locked and cannot be displaced laterally, so that the position of the side sealing plate is locked to prevent the side sealing plate from shifting in position and affecting the final welding quality.

[0013] Optionally, the locking member includes a rack plate arranged on the pushing disk, an engaging block matching the rack plate is longitudinally slidably connected to the welding table through an elastic member, and a trapezoidal slope is arranged on the moving frame which can push the engaging block to approach the rack plate when the moving frame moves away from the center of the welding table.

[0014] By adopting the above technical solution, when the moving frame moves away from the center of the welding table, the trapezoidal slope will gradually pressurize the engaging block, so that the engaging block gradually approaches the rack plate until the engaging block engages with the rack plate to lock the position of the push plate.

[0015] Optionally, the loading column is hollow, and the inner cavity of the loading column is communicated with the sliding cavity of the damping spring pin, and a limiting column capable of penetrating the loading column is arranged on the movable frame.

[0016] By adopting the above technical solution, when the side sealing plate does not enter the openings at both ends of the U-profile, the limit column can limit the damping spring pin, and at this time the damping spring pin cannot be retracted into the loading column due to the blocking and limiting of the limit column. On the contrary, when the side sealing plate enters the openings at both ends of the U-profile, since the limit column and the moving frame are integrally arranged, the limit column can move with the moving frame to release the limit on the damping spring pin.

[0017] Optionally, the pushing plate consists of a pushing plate, an adjusting plate and an adjusting screw. The pushing plate and the adjusting plate are both laterally slidably connected to the loading column. The adjusting plate is located outside the pushing plate and is fixedly connected to the first spring. The adjusting screw is rotatably connected to the pushing plate and is threadedly connected to the adjusting plate.

[0018] By adopting the above technical solution, when a person turns the adjusting screw, the distance between the push plate and the adjusting plate will change accordingly, thereby changing the compression deformation amplitude of the first spring, so that the elastic potential energy generated by the first spring can be kept within a normal range according to the actual loading amount of the side sealing plate.

[0019] Optionally, two left-right symmetrical cylinders are vertically arranged on the welding table, and the execution ends of the cylinders are each provided with a pressing plate capable of pressing the side sealing plate.

[0020] By adopting the above technical solution, when the side sealing plate and the U-profile are in place, the pressure plate will move downward under the drive of the cylinder and press the side sealing plate tightly. Under the pressure limit of the pressure plate, the side sealing plate can participate in the welding work more stably, further improving the quality of the welding work.

[0021] Optionally, a lifting plate is vertically slidably connected to the transfer vehicle, the U-profiles can be placed on the lifting plate in a vertical stacked form, and the transfer vehicle is provided with a driving member for driving the lifting plate to vertically lift and lower.

[0022] By adopting the above technical solution, when the transfer vehicle is located directly below the welding table, the driving member operates to drive the lifting plate to rise, thereby completing the automatic loading of the U-profile.

[0023] Optionally, a limit member is provided between the welding table and the transfer vehicle, for locking and limiting the transfer vehicle when the transfer vehicle moves to a position directly below the welding table.

[0024] Optionally, the limiting member includes a ball head spring pin arranged on the welding table, and a limiting hole for inserting the ball head spring pin is provided on the transfer vehicle.

[0025] By adopting the above technical solution, when the transfer vehicle moves to the bottom of the welding table, the ball head spring pin will be inserted into the inside of the limiting hole to provide a limiting effect for the transfer vehicle to prevent the transfer vehicle from shifting in position during the subsequent loading process and causing the loading position of the U-profile to change.

[0026] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects: 1. During welding, the loading limiter is used to keep the loading position of each side sealing plate consistent, so as to meet the welding work of large quantities of side sealing plates. At the same time, the U-profile and the side sealing plate can be accurately aligned when they arrive at the welding station, while taking into account the welding accuracy and reducing the operation time of the welding work, thereby improving the overall efficiency of the welding work.

[0027] 2. Optimize the limit assembly of the side sealing plate, and use the position of the U-profile as the trigger condition of the limit assembly to reduce the possibility of the side sealing plate shifting or slipping off the loading column during welding, thereby improving the final quality of the welding work.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 8 , the technical solutions of the embodiments of the present application are clearly and completely described. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0031] Reference Figure 1 The present embodiment provides a construction formwork welding sealing device, comprising a welding platform 1, a transfer vehicle 2, a loading mechanism and two welding mechanical arms 11. The transfer vehicle 2 is used to carry and transfer the U-shaped material 7, and the two welding mechanical arms 11 are symmetrically arranged on the welding platform 1.

[0032] Among them, refer to Figure 1 and Figure 2 The feeding mechanism includes a linear actuator 3, a limit block 31, a loading column 4, a push plate 41, a first spring 42 and a damping spring pin 43. Two linear actuators 3 are provided and are symmetrically arranged on the welding table 1. The execution end of each linear actuator 3 is provided with a limit block 31. When the linear actuator 3 drives the limit block 31 to move horizontally, it can drive the U-shaped material 7 to move horizontally together; the loading columns 4 are symmetrically arranged on the welding table 1 in a horizontal arrangement of two groups, and the loading columns 4 match the through holes on the side sealing plate 8 to support the side sealing plate 8. The two loading columns 4 in the same group are connected with a push plate 41 through the first spring 42 for horizontal sliding, and the unloading end of each loading column 4 is provided with a damping spring pin 43. When the limit block 31 is driven by the linear actuator 3 to move to the limit position away from the center of the welding table 1, the distance between the limit block 31 and the corresponding damping spring pin 43 is consistent with the thickness of the side sealing plate 8.

[0033] In the initial state, the two limit blocks 31 are driven by the linear actuator 3 to be in the extreme position away from the center of the welding table 1, and the push plate 41 will push the side sealing plate 8 to move toward the position close to the center of the welding table 1 under the action of the first spring 42, and the damping spring pin 43 can limit the side sealing plate 8 at the unloading end of the loading column 4. When the transfer vehicle 2 moves the U-shaped material 7 to the middle of the welding table 1, the linear actuator 3 on the right side drives the limit block 31 on the right side to move to the left, and the U-shaped material 7 will move to the left under the push of the limit block 31 on the right side until the U-shaped material 7 abuts against the limit block 31 on the left. In this state, the side sealing plate 8 abutted by the damping spring pin 43 will enter the left end opening of the U-shaped material 7 and match the left end face of the U-shaped material 7. Then, the side sealing plate 8 and the U-shaped material 7 are welded together by the cooperation of the welding robot arm 11, and then the two linear actuators 3 are synchronously operated to move the two limit shift blocks 31 and the U-shaped material 7 to the right together, and because the side sealing plate 8 and the U-shaped material 7 have been welded into a complete whole, the side sealing plate 8 will overcome the elastic resistance of the damping spring pin 43 and move normally to the right. When the U-shaped material 7 moves to the rightmost end, repeat the above steps to carry out the welding of the side sealing plate 8 on the right side.

[0034] Reference Figure 2 The limit shift block 31 is provided with an adjusting bolt 32 for adjusting the distance between the limit shift block 31 and the corresponding damping spring pin 43 when the limit shift block 31 moves to an extreme position away from the center of the welding table 1.

[0035] Personnel can appropriately adjust the adjusting bolt 32 according to the rear end of the side sealing plate 8, so that the limit position of the limit shift block 31 when moving changes, so as to meet the use requirements of side sealing plates 8 of different thicknesses.

[0036] Reference Figure 2 , Figure 3 and Figure 4 , the welding table 1 is provided with an auxiliary positioning assembly, which includes a moving frame 5, a second spring 51 and a locking member 52. Two moving frames 5 are provided and are symmetrically arranged on the welding table 1 in a transverse sliding connection through the second spring 51, and both moving frames 5 can be abutted by the U-shaped material 7; the locking member 52 includes a rack plate 521, a chimeric block 522 and a trapezoidal slope 523, the rack plate 521 is provided on the push plate 41, the chimeric block 522 is longitudinally slidably connected to the welding table 1 through an elastic member, and the chimeric block 522 can mesh with the rack plate 521, and the trapezoidal slope 523 is provided on the moving frame 5, when the moving frame 5 is away from the center of the welding table 1, the trapezoidal slope 523 can cause the chimeric block 522 to approach the rack plate 521.

[0037] When the U-profile 7 moves toward the side sealing plate 8 and abuts the moving frame 5, the moving frame 5 will overcome the elastic force of the second spring 51 and move in the direction away from the center of the welding table 1. The cooperation of the trapezoidal slope 523 can prompt the engaging block 522 to approach the rack plate 521 until the engaging block 522 engages with the rack plate 521. At this time, the pushing plate 41 and the side sealing plate 8 abutting against it cannot be displaced laterally, thereby reducing the possibility of position displacement of the side sealing plate 8 during welding and affecting the final welding quality.

[0038] Reference Figure 3 and Figure 5 The loading column 4 is hollow, and the inner cavity of the loading column 4 is connected to the sliding cavity of the damping spring pin 43 . The moving frame 5 is provided with a limiting column 53 that can penetrate the loading column 4 .

[0039] When the side sealing plate 8 does not enter the openings at both ends of the U-profile 7, the limiting column 53 can limit the damping spring pin 43 inside the loading column 4, so that the damping spring pin 43 cannot shrink toward the inside of the loading column 4, so as to prevent the side sealing plate 8 from falling off from the loading column 4 under the action of the pushing plate 41 and the first spring 42. When the side sealing plate 8 enters the openings at both ends of the U-profile 7, the moving frame 5 is abutted by the U-profile 7 and moves in a direction away from the center of the welding table 1. The limiting column 53 will move with the moving frame 5 and release the limit on the damping spring pin 43, so that the welded side sealing plate 8 can move with the U-profile 7 and fall off from the loading column 4.

[0040] In addition, refer to Figure 2 and Figure 3 The pushing plate 41 is composed of a pushing plate 411, an adjusting plate 412 and an adjusting screw 413. The pushing plate 411 and the adjusting plate 412 are both laterally slidably connected to the loading column 4. The adjusting plate 412 is located on the outside of the pushing plate 411 and is fixedly connected to the first spring 42. The adjusting screw 413 is rotatably connected to the pushing plate 411 and is threadedly connected to the adjusting plate 412.

[0041] When the number of side sealing plates 8 loaded on the loading column 4 is small, personnel can adjust the distance between the pushing plate 411 and the adjusting plate 412 by adjusting the screw 413, so that the first spring 42 undergoes a certain degree of compression deformation to prevent the first spring 42 from failing and being unable to apply normal elastic pressure to the pushing plate 41.

[0042] Reference Figure 1 , Figure 2 and Figure 6 Two left-right symmetrical cylinders 6 are vertically arranged on the welding table 1, and the execution ends of the cylinders 6 are each provided with a pressing plate 61 capable of pressing the side sealing plate 8.

[0043] Before welding is carried out, the operation of the cylinder 6 drives the pressing plate 61 to move downward, so that the pressing plate 61 can press and limit the side sealing plate 8 located in the opening of the U-profile 7, thereby further improving the stability of the welding work.

[0044] Reference Figure 1 and Figure 7 A lifting plate 21 is vertically slidably connected to the transfer vehicle 2, and the U-profile 7 can be placed on the lifting plate 21 in a vertical stacked form, and a driving member 22 is provided on the transfer vehicle 2 for driving the lifting plate 21 to vertically lift and lower.

[0045] When the transfer vehicle 2 moves to the bottom of the welding table 1, the lifting plate 21 is moved upward by the cooperation of the driving member 22, so that the U-shaped material 7 loaded on the lifting plate 21 can be raised to the welding station in the middle of the welding table 1 to quickly carry out subsequent welding work.

[0046] Among them, refer to Figure 7 and Figure 8 A limiting member 23 is provided between the welding table 1 and the transfer vehicle 2, and is used to lock and limit the transfer vehicle 2 when the transfer vehicle 2 moves to the position directly below the welding table 1. The limiting member 23 includes a ball spring pin 231 and a limiting hole 232, wherein the ball spring pin 231 is provided on the welding table 1, and the limiting hole 232 is provided on the transfer vehicle 2, and the ball spring pin 231 can be inserted into the limiting hole 232.

[0047] When the transfer vehicle 2 moves to the bottom of the welding table 1, the ball spring pin 231 will be inserted into the limiting hole 232, thereby locking the relative position of the transfer vehicle 2 and the welding table 1, so that the U-profile 7 can be stably and accurately transferred to the welding station in the middle of the welding table 1.

[0048] The implementation principle of a building template welding sealing device in the embodiment of the present application is: In the initial state, the two limit blocks 31 will be in the extreme position away from the center of the welding table 1 driven by the linear drive 3, and the push plate 41 will push the side sealing plate 8 to move toward the position close to the center of the welding table 1 under the action of the first spring 42. At the same time, the damping spring pin 43 can limit the side sealing plate 8 at the unloading end of the loading column 4.

[0049] When the transfer vehicle 2 moves to the bottom of the welding table 1 and the U-profile 7 is moved to the middle of the welding table 1 through the cooperation of the driving member 22, the linear drive 3 on the right side drives the limit block 31 on the right side to move to the left, and the U-profile 7 will move to the left under the push of the limit block 31 on the right side until the U-profile 7 abuts against the limit block 31 on the left. In this state, the side sealing plate 8 limited by the damping spring pin 43 will enter the left end opening of the U-profile 7 and be flush with the left end face of the U-profile 7.

[0050] Subsequently, the side sealing plate 8 and the U-profile 7 are welded together through the cooperation of the welding robot arm 11, and then the two linear drives 3 operate synchronously to move the two limit blocks 31 and the U-profile 7 to the right together. Since the side sealing plate 8 and the U-profile 7 have been welded as a complete whole, the side sealing plate 8 will overcome the elastic resistance of the damping spring pin 43 and move normally to the right. When the U-profile 7 moves to the rightmost end, repeat the above steps to carry out the welding work of the side sealing plate 8 on the right side.

[0051] In addition, when the U-profile 7 moves toward the side sealing plate 8 and abuts the movable frame 5, the movable frame 5 will overcome the elastic force of the second spring 51 and move in the direction away from the center of the welding table 1. The cooperation of the trapezoidal slope 523 can cause the engaging block 522 to approach the rack plate 521 until the engaging block 522 engages with the rack plate 521. At this time, the pushing plate 41 and the side sealing plate 8 abutting therefrom cannot undergo lateral displacement.

[0052] When the side sealing plate 8 does not enter the openings at both ends of the U-shaped material 7, the limiting column 53 can limit the damping spring pin 43 inside the material loading column 4, so that the damping spring pin 43 cannot shrink toward the inside of the material loading column 4, so as to prevent the side sealing plate 8 from falling off from the material loading column 4 under the action of the pushing plate 41 and the first spring 42. On the contrary, when the side sealing plate 8 enters the openings at both ends of the U-shaped material 7, the moving frame 5 is abutted by the U-shaped material 7 and moves in a direction away from the center of the welding table 1, and the limiting column 53 will move with the moving frame 5 and release the limiting of the damping spring pin 43, so that the welded side sealing plate 8 can move with the U-shaped material 7 and fall off from the material loading column 4.

[0053] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
