Description

Technical Field

[0001] The present invention relates to the technical field of mesh welding, and particularly to a mesh welding device capable of lateral movement and a working method thereof. Background Art

[0002] Traditional mesh welding equipment generally does not adopt a moving method. Instead, the upper welding seat and the lower welding seat on the welding equipment move up and down simultaneously to weld the horizontal bars and vertical bars. However, this causes the upper welding seat and the lower welding seat of the welding equipment to need to adjust the lateral positions of the upper welding seat and the lower welding seat when facing meshes with different spacings. The adjustment process is rather troublesome, and the adjusted spacing is not easy to control.

[0003] Therefore, it is necessary to design a mesh welding device capable of lateral movement and a working method thereof, which can be adapted to the welding of meshes with different spacings. Summary of the Invention

[0004] Aiming at the above-mentioned existing technical deficiencies, the purpose of the present invention is to provide a mesh welding device capable of lateral movement and a working method thereof, which can be adapted to the welding of meshes with different spacings.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: The present invention provides a mesh welding device capable of lateral movement and a working method thereof, including a horizontal numerical control displacement mechanism, a welding mechanism, and a mounting frame. The welding mechanism includes an upper welding seat and a lower welding seat. The upper welding seat is located directly above the lower welding seat. The numerical control displacement mechanism includes an upper connecting seat, a lower connecting seat, and a lateral movement mechanism for driving the upper connecting seat and the lower connecting seat to move horizontally simultaneously. The upper welding seat is mounted on the upper connecting seat through a first lifting mechanism and can move up and down. The lower welding seat is mounted on the lower connecting seat through a second lifting mechanism and can move up and down. The upper welding seat is divided into multiple welding single seats. The first lifting mechanism includes multiple single cylinders respectively used for driving the multiple upper welding seats to move vertically downward.

[0006] Preferably, the lateral movement mechanism includes two transmission shafts and a rotation driver for driving one of the transmission shafts to rotate. Two sets of pulley groups are installed between the two transmission shafts. The upper connecting seat is fixedly connected to the belt in the upper pulley group, and the lower connecting seat is fixedly connected to the belt in the lower pulley group. The upper connecting seat and the lower connecting seat are mounted on the mounting frame through a guide seat and a guide rail and can slide horizontally.

[0007] Preferably, it further includes a lifting mechanism, a positioning seat, a positioning rod and two clamping mechanisms. Each transmission shaft includes an upper half shaft and a lower half shaft. The clamping mechanism can be vertically slidably clamped between the upper half shaft and the lower half shaft, and the clamping mechanism is rotatably installed on the connecting shaft of the lifting mechanism. The lifting mechanism is fixedly installed on the lower connecting seat, the positioning rod is fixedly installed on the connecting shaft, the positioning seat is fixedly installed on the upper connecting seat, a triangular groove for inserting the positioning rod is formed on the positioning seat, and the top of the positioning rod is a sharp corner structure.

[0008] Preferably, each clamping mechanism includes a spline tube, a spring and a rotating seat. The mutually adjacent ends of the upper half shafts are both spline structures. The spline tube is sleeved on the upper half shaft and the lower half shaft, and retaining rings are arranged at both ends of the spline tube. The spline tube can be slidably inserted into the rotating seat, the spring is used to apply a downward elastic force to the spline tube, and the rotating seat is fixedly connected to the connecting shaft.

[0009] Preferably, the lifting mechanism includes a connecting shaft, a conduit, a lifter and a support frame. The conduit is fixedly installed on the lower connecting seat, the positioning rod is inserted into the conduit, the connecting shaft is horizontally arranged and fixedly connected to the positioning rod. An avoidance hole for the connecting shaft to pass through is formed on the conduit. The lifter is fixedly installed on the conduit, the lifting seat of the conduit is fixedly connected to the connecting shaft, the clamping mechanism is fixedly connected to the support frame, the limiting rod is horizontally slidably connected to the connecting shaft, and the positioning rod is fixedly connected to the connecting shaft.

[0010] Preferably, the lifter includes a gear, a rack and a motor. The rack is fixedly installed on the lifting seat, the gear meshes with the rack, the gear is rotatably installed on the conduit through a rotating shaft, the motor is fixedly installed on the conduit, and the output end of the motor is fixedly connected to the rotating shaft.

[0011] Preferably, a limiting rod is fixedly arranged on the mounting frame, the top of the limiting rod abuts against the bottom of the support frame, and a conduit is fixedly arranged on the support frame, and the connecting shaft is inserted into the conduit.

[0012] A working method of a laterally movable mesh welding device and the working method include the following steps: Step 1: The lateral numerical control displacement mechanism works to drive the upper connecting seat and the lower connecting seat to move horizontally synchronously, and the welding mechanism moves along with it; Step 2: When moving to the target position, multiple single cylinders respectively push multiple welding single seats downward to weld the joints of the horizontal ribs and vertical ribs; Step 3: Repeat the movements of Step 1 and Step 2 multiple times until the entire lateral part of the mesh is welded; Step 4: After all welding is completed, correct the offsets of the upper welding seat and the lower welding seat. The lifting mechanism pushes the positioning rod and the clamping mechanism to move upward synchronously. The clamping mechanism first separates from the lower half shaft, and then the positioning rod contacts the clamping mechanism; Step Five: If there is an offset, the positioning rod is laterally pushed by the inclined surface of the positioning seat to adjust the positions of the upper welding seat and the lower welding seat.

[0013] The beneficial effects of the present invention are as follows: For the horizontally movable mesh welding device and working method, by dividing the upper welding seat into multiple welding single seats, and each welding single seat can be controlled to move up and down by a single cylinder, and the multiple welding single seats and the lower welding seat can be driven to move synchronously by a horizontal movement mechanism, it is possible to weld the intersections of multiple horizontal ribs and vertical ribs. By moving and welding in this way, it can be adapted to the welding of meshes with different spacings.

[0014] And when the belt on the pulley set slips, the positioning rod can be pushed upward by the lifting mechanism to be engaged with the positioning seat. And before the engagement, the engaging mechanism can be separated from the upper half shaft and the lower half shaft, so that when the belt slips, the thrust generated by the engagement of the positioning rod and the positioning seat can push the belt on the lower side to move horizontally, so that the dislocation between the upper welding seat and the lower welding seat can be pushed back into place.

[0015] And during the above-mentioned reset process, the lower half shaft will rotate. If the engaging mechanism cannot form an engagement when descending, the spline tube can be pressed against the lower half shaft by a spring. When the upper half shaft rotates slightly later, the engagement can be achieved through the engaging mechanism, ensuring the smooth engagement after adjustment.

[0016] And by connecting the positioning rod and the engaging mechanism through a connecting shaft, it is ensured that before the positioning seat and the positioning rod are engaged, the engaging mechanism is necessarily separated from the lower half shaft. And although the engaging mechanism is connected to the connecting shaft with horizontal displacement, through the action of the connecting shaft, it is avoided that the horizontal displacement will push the engaging mechanism to move horizontally, ensuring that the engaging mechanism can always be connected to the upper half shaft and the lower half shaft to transmit power. And through the action of the guide sleeve and the limiting rod, the length of the connecting shaft can be shortened. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment: The present invention provides a mesh welding device capable of horizontal movement and a working method, as Figure 1-8As shown in the figure, it includes a horizontal numerically controlled displacement mechanism 1, a welding mechanism 2 and a mounting bracket 3. The welding mechanism 2 includes an upper welding seat 2a and a lower welding seat 2b. The upper welding seat 2a is located directly above the lower welding seat 2b. The numerically controlled displacement mechanism 1 includes an upper connecting seat 1a, a lower connecting seat 1b and a horizontal moving mechanism for driving the upper connecting seat 1a and the lower connecting seat 1b to move horizontally at the same time. The upper welding seat 2a is installed on the upper connecting seat 1a through a first lifting mechanism and can move up and down. The lower welding seat 2b is installed on the lower connecting seat 1b through a second lifting mechanism and can move up and down. Among them, both the first lifting mechanism and the second lifting mechanism are cylinders. Through the operation of the first lifting mechanism and the second lifting mechanism, the upper welding seat 2a and the lower welding seat 2b will be pushed to move closer inward, so that the upper welding seat 2a and the lower welding seat 2b will extrude the horizontal ribs and vertical ribs. And through the principle of spot welding, the joints of the horizontal ribs and vertical ribs are welded. Through this horizontally movable method, the moving distance can be adjusted according to the length and width requirements of the mesh. And the upper welding seat 2a is divided into multiple welding single seats. The first lifting mechanism includes multiple single cylinders respectively used to drive the multiple upper welding seats 2a to move vertically downward. Since the gaps between the multiple vertical ribs of the building material mesh are different, after the multiple upper welding seats 2a are driven by the horizontal moving mechanism to move, and then through programming to control the multiple single cylinders according to the needs of the moving position, the multiple single cylinders are controlled to push the multiple welding single seats downward specifically, and the joints of the horizontal ribs and vertical ribs can be welded.

[0029] Through the above horizontal moving mechanism and single cylinders to drive the welding single seats to move horizontally and downward, it can be applicable to the welding of meshes of various specifications.

[0030] The horizontal moving mechanism includes two transmission shafts 1d and a rotary driver 1e for driving one of the transmission shafts 1d to rotate. Two pulley groups 1c are installed between the two transmission shafts 1d. Each pulley group 1c includes a belt and two pulleys. The two pulleys are respectively fixedly connected to the two transmission shafts 1d. The upper connecting seat 1a is fixedly connected to the belt in the upper pulley group 1c, and the lower connecting seat 1b is fixedly connected to the belt in the lower pulley group 1c. Through the operation of the pulley group 1c, the pulley group 1c will drive one of the transmission shafts 1d to rotate. Through the action of the pulley group 1c, the other transmission shaft 1d will be driven to rotate, that is, through the rotation of the two belts, the lower welding seat 2b and the lower welding seat 2b are driven to move horizontally synchronously. The upper connecting seat 1a and the lower connecting seat 1b are installed on the mounting bracket 3 through a guide seat and a guide rail and can slide horizontally. The guide seat and the guide rail provide a supporting force and a guiding function for the upper connecting seat 1a and the lower connecting seat 1b.

[0031] It further includes a lifting mechanism 4, a positioning seat 5, a positioning rod 6 and two clamping mechanisms 7. Each transmission shaft 1d includes an upper half shaft 1d1 and a lower half shaft 1d2. The clamping mechanism 7 can be vertically slidably clamped between the upper half shaft 1d1 and the lower half shaft 1d2. The clamping mechanism 7 is rotatably mounted on the connecting shaft 4b of the lifting mechanism 4. The lifting mechanism 4 is fixedly mounted on the lower connecting seat 1b. The positioning rod 6 is fixedly mounted on the connecting shaft 4b. When the lifting mechanism 4 works, it will simultaneously push the clamping mechanism 7 and the positioning rod 6 to move vertically upward. The positioning seat 5 is fixedly mounted on the upper connecting seat 1a. A triangular groove for the positioning rod 6 to insert is formed on the positioning seat 5. The top of the positioning rod 6 is a pointed structure. When the positioning rod 6 and the clamping mechanism 7 move upward simultaneously, before the positioning rod 6 contacts the positioning seat 5, the clamping mechanism 7 will be completely separated from the lower half shaft 1d2. At this time, the upper half shaft 1d1 and the lower half shaft 1d2 can rotate freely. When the positioning rod 6 is subsequently inserted into the interior of the positioning seat 5, if there is a misalignment deviation between the upper welding seat 2a and the lower welding seat 2b, this deviation is caused by the slipping between the belt and the pulley. The end of the positioning rod 6 will not be able to be just clamped with the positioning seat 5. The end of the positioning rod 6 will perform a horizontal displacement along the inclined surface of the positioning seat 5. The positioning rod 6 will drive the belt connected to it through the lower connecting seat 1b to move, that is, the positioning adjustment is completed. After the adjustment is completed, the positioning rod 6 is separated from the positioning seat 5. The gap between the two is used for the longitudinal bars to pass through. The clamping mechanism 7 will be clamped downward with the lower half shaft 1d2, that is, the upper half shaft 1d1 and the lower half shaft 1d2 are connected again, so that the upper and lower groups of pulley sets 1c can work synchronously.

[0032] Each clamping mechanism 7 includes a spline tube 7a, a spring 7b, and a swivel base 7c. The mutually approaching ends of the upper half shafts 1d1 are both spline structures. The spline tube 7a is sleeved on the upper half shafts 1d1 and the lower half shafts 1d2. Retaining rings are provided at both ends of the spline tube 7a. The spline tube 7a is slidably inserted into the swivel base 7c. The spring 7b is used to apply a downward elastic force to the spline tube 7a. The spring 7b is sleeved on the outer edge of the spline tube 7a. The top of the spring 7b abuts against the swivel base 7c, and its bottom abuts against the bottom retaining ring of the spline tube 7a. The swivel base 7c is fixedly connected to the connecting shaft 4b. When the connecting shaft 4b moves downward, the swivel base 7c will drive the spline tube 7a to be withdrawn from the lower half shaft 1d2. After the positioning seat 5 and the positioning rod 6 are adjusted, the spline tube 7a moves downward. If the spline tube 7a cannot be just inserted into the lower half shaft 1d2, the spring 7b will be compressed. When the upper half shaft 1d1 rotates subsequently, it will drive the spline tube 7a to rotate, so that under the pushing action of the spring 7b, the spline tube 7a is clamped with the lower half shaft 1d2. It should be noted that when the upper half shaft 1d1 rotates, it will only drive the upper welding seat 2a to move. During the process of the spline tube 7a being inserted, a slight misalignment will occur between the upper welding seat 2a and the lower welding seat 2b. This misalignment will not affect the welding because the bottom of the single welding seat has a relatively large width. The adjustment between the positioning seat 5 and the positioning rod 6 is to avoid a large misalignment error.

[0033] The lifting mechanism 4 includes a connecting shaft 4b, a conduit 4c, a lifter 4d, and a support frame 4h. The conduit 4c is fixedly installed on the lower connecting seat 1b. The positioning rod 6 is inserted into the conduit 4c. The connecting shaft 4b is horizontally arranged and fixedly connected to the positioning rod 6. An avoidance hole for the connecting shaft 4b to pass through is provided on the conduit 4c. The lifter 4d is fixedly installed on the conduit 4c. The lifting seat 4d4 of the conduit 4c is fixedly connected to the connecting shaft 4b. The clamping mechanism 7 is fixedly connected to the support frame 4h. The limit rod 4f is horizontally slidably connected to the connecting shaft 4b. A guide hole for the connecting shaft 4b to pass through is provided on the limit rod 4f. The positioning rod 6 is fixedly connected to the connecting shaft 4b. By driving the non-connecting shaft 4b to move upward through the lifter 4d, the positioning rod 6 and the clamping mechanism 7 can be driven to move upward synchronously. When the lower connecting seat 1b moves horizontally, the lower connecting seat 1b will drive the entire lifting mechanism 4 to move horizontally through the conduit 4c. Since the connecting shaft 4b is horizontally slidably connected to the support frame 4h, the connecting shaft 4b will not push the support frame 4h to move laterally, ensuring that the clamping mechanism 7 can only move up and down along with the connecting shaft 4b. Through the above method, the lifting mechanism 4 can drive the positioning rod 6 and the clamping mechanism 7 to move up and down during the lifting movement, and when the lower connecting seat 1b drives the lifting mechanism 4 to move horizontally, it will only drive the positioning rod 6 to move horizontally and will not drive the clamping mechanism 7 to move horizontally.

[0034] The lifter 4d includes a gear 4d1, a rack 4d2, and a motor 4d3. The rack 4d2 is fixedly installed on the lifting seat 4d4. The gear 4d1 meshes with the rack 4d2. The gear 4d1 is rotatably installed on the conduit 4c through a rotating shaft. The motor 4d3 is fixedly installed on the conduit 4c, and the output end of the motor 4d3 is fixedly connected to the rotating shaft. By controlling the motor 4d3 to work, the motor 4d3 will drive the gear 4d1 to rotate through the rotating shaft, so that the gear 4d1 pulls the lifting seat 4d4 to move vertically upward through the rack 4d2, and the lifting seat 4d4 will drive the connecting shaft 4b to move vertically upward.

[0035] A limiting rod 4f is fixedly arranged on the mounting frame 3. The top of the limiting rod 4f abuts against the bottom of the support frame 4h. A conduit 4c is fixedly arranged on the support frame 4h. The connecting shaft 4b is inserted into the conduit 4c. By arranging the limiting rod 4f, the connecting shaft 4b can be pulled out and separated from the support frame 4h, that is, the length of the connecting shaft 4b can be shortened. And by arranging the guide sleeve 4e, the length of the connecting shaft 4b can be further shortened, avoiding the danger that the connecting shaft 4b extends too long when moving to the extreme position to the left or right.

[0036] A working method of a laterally movable mesh welding device and a working method thereof includes the following steps: Step 1: The lateral numerical control displacement mechanism 1 works to drive the upper connecting seat 1a and the lower connecting seat 1b to move horizontally synchronously, and the welding mechanism 2 moves along with it; Step 2: When moving to the target position, a plurality of single cylinders respectively push a plurality of welding single seats to move downward to weld the joints of the horizontal ribs and the vertical ribs; Step 3: Repeat the movements of Step 1 and Step 2 multiple times until all the horizontal parts of the mesh are welded; Step 4: After all the welding is completed, correct the offset of the upper welding seat 2a and the lower welding seat 2b. The lifting mechanism 4 pushes the positioning rod 6 and the clamping mechanism 7 to move upward synchronously. The clamping mechanism 7 first separates from the lower half shaft 1d2, and then the positioning rod 6 contacts the clamping mechanism 7; Step 5: If an offset occurs, the positioning rod 6 is laterally pushed by the inclined surface of the positioning seat 5 to adjust the positions of the upper welding seat 2a and the lower welding seat 2b.

[0037] When in use, for the laterally movable mesh welding device and the working method thereof, by dividing the upper welding seat into a plurality of welding single seats, and each welding single seat can be controlled to move up and down by a single cylinder, and by driving the plurality of welding single seats and the lower welding seat to move synchronously through the lateral moving mechanism, it can weld the intersections of a plurality of horizontal ribs and vertical ribs. By moving and welding in this way, it can be adapted to the welding of meshes with different spacings.

[0038] And when the belt on the pulley set slips, the positioning rod 6 can be pushed upward by the lifting mechanism 4 to be clamped with the positioning seat 5. And before the clamping, the clamping mechanism 7 can be separated from the upper half shaft 1d1 and the lower half shaft 1d2, so that when the belt slips, the thrust generated by the clamping of the positioning rod 6 and the positioning seat 5 can push the belt on the lower side to move horizontally, so that the dislocation between the upper welding seat 2a and the lower welding seat 2b can be pushed back to the original position.

[0039] And during the above reset process, the lower half shaft 1d2 will rotate. If the clamping mechanism 7 cannot form a clamp when it descends, the spline tube 7a can be pressed against the lower half shaft 1d2 by the spring 7b. When the upper half shaft 1d1 rotates slightly subsequently, the clamping can be achieved through the clamping mechanism 7, ensuring the smooth clamping after adjustment.

[0040] And the positioning rod 6 and the clamping mechanism 7 are connected by the connecting shaft 4b, ensuring that before the positioning seat 5 and the positioning rod 6 are clamped, the clamping mechanism 7 is necessarily separated from the lower half shaft 1d2. And although the clamping mechanism 7 is connected to the connecting shaft 4b with horizontal displacement, due to the action of the connecting shaft 4b, it is avoided that the horizontal displacement will push the clamping mechanism 7 to move horizontally, ensuring that the clamping mechanism 7 can be continuously connected to the upper half shaft 1d1 and the lower half shaft 1d2 to transmit power. And through the action of the guide sleeve 4e and the limit rod 4f, the length of the connecting shaft 4b can be shortened.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
