Description

Technical Field

[0001] The invention relates to the technical field of building material production, in particular to a rivet welding device. Background Art

[0002] With the development of concrete technology, the technology of concrete pipe piles has become increasingly mature. In addition to being used in industrial and civil buildings, it is also widely used in various fields such as bridges, ports, railways or water conservancy projects. Concrete pipe piles include various types such as end plate concrete square piles. The end plate concrete square piles are formed by connecting a hoop at each end of the square pile, assembling it at the two ends of the cage reinforcement, and pouring concrete. In the process of assembling the hoop and the cage reinforcement, it is necessary to assemble the hoop and the cage reinforcement into one by riveting, and position the hoop.

[0003] At present, in the assembly process of the hoop and the cage reinforcement, the rivet buckle and the hoop are usually positioned and welded by manual grasping. However, this welding method has low work efficiency and high labor intensity. In addition, when the rivet buckle is manually welded to the hoop, the welding position is prone to deviation, which seriously affects the welding quality of the rivet buckle. Summary of the invention

[0044] The technical solution provided by the embodiments of the present invention is described below in conjunction with the accompanying drawings.

[0045] like Figure 1-Figure 3 As shown, the present invention provides a rivet button welding device 100, which includes a frame 110, a feeding mechanism 120, a welding mechanism 130 and a conveying mechanism 140. The frame 110 has a material taking station and a welding station, the feeding mechanism 120 is installed on the frame 110 by screwing, welding, etc., the feeding mechanism 120 is used to send the rivet button to the material taking station, and the rivet button welding device 100 is used to weld the rivet button to the hoop.

[0046] The conveying mechanism 140 is spaced apart from the frame 110, and is used to convey the ferrule to the welding station to prepare for welding the rivet buckle on the ferrule. In this embodiment, the conveying mechanism 140 is fixed on the work surface, such as fixing the conveying mechanism 140 on the ground of the operation area, and the conveying mechanism 140 is spaced apart from the frame 110. When the rivet buckle needs to be welded on the ferrule, the corresponding ferrule can be conveyed to the welding station by the conveying mechanism 140.

[0047] The welding mechanism 130 can move between the material taking station and the welding station, that is, the welding mechanism 130 is movably connected to the frame 110. During the movement of the welding mechanism 130, the welding mechanism 130 can move between the material taking station and the welding station. Specifically, the welding mechanism 130 includes a welding clamp body 131, a clamping assembly 132 and a welding assembly 133. The clamping assembly 132 and the welding assembly 133 are arranged on the welding clamp body 131 by screw connection, welding, etc. The welding clamp body 131 is movably arranged on the frame 110. When the welding clamp body 131 moves on the frame 110, the welding clamp body 131 drives the clamping assembly 132 and the welding assembly 133 to move between the material taking station and the welding station. The clamping assembly 132 is used to grab and release the rivet buckle, and the welding assembly 133 is used to weld the rivet buckle to the hoop. In this embodiment, when the welding clamp body 131 drives the clamping assembly 132 to move to the material picking station, the clamping assembly 132 grabs the rivet at the material picking station; and when the welding clamp body 131 drives the clamping assembly 132 and the welding assembly 133 to move to the welding station, the welding assembly 133 welds the rivet at the welding station, and after the welding operation of the rivet is completed, the clamping assembly 132 can release the rivet to facilitate the resetting of the welding mechanism 130 and prepare for the next welding operation of the rivet.

[0048] In the above-mentioned rivet welding device 100, the feeding mechanism 120 is installed on the frame 110, and is used to feed the rivet to the material picking station. The welding mechanism 130 moves to the material picking station, and grabs the rivet located at the material picking station through the clamping component 132. After the clamping component 132 grabs the rivet, the welding clamp body 131 moves to the welding station with the clamping component 132 and the welding component 133, and the rivet is welded to the hoop of the conveying mechanism 140 through the welding component 133. After completing the welding operation of the rivet on the hoop, the clamping component 132 releases the rivet, and the welding mechanism 130 is reset to prepare for the next welding operation of the rivet. The above-mentioned rivet welding device 100 can significantly improve the welding efficiency of the rivets, reduce labor intensity, ensure the consistency of the welding position and welding points of the rivets on the ferrule, and greatly improve the welding quality of the rivets on the ferrule through the movement of the welding mechanism 130 between the material picking station and the welding station, and cooperate with the feeding mechanism 120 and the conveying mechanism 140 to automatically complete the rivet welding operation on the ferrule.

[0049] In order to grasp and release the rivet buckle, a preferred embodiment is as follows: Figure 1 and Figure 3As shown, the clamping assembly 132 includes a first driving member 1321, a first clamping plate 1322 and a second clamping plate 1323, and the first clamping plate 1322 and the second clamping plate 1323 are movably arranged on the welding clamp body 131 to achieve the fixation between the first clamping plate 1322 and the second clamping plate 1323, and to facilitate the adjustment of the distance between the first clamping plate 1322 and the second clamping plate 1323. The first clamping plate 1322 and the second clamping plate 1323 are arranged opposite to each other, that is, there is a distance between the first clamping plate 1322 and the second clamping plate 1323. The first driving member 1321 is fixed to the welding clamp body 131 by screw connection, welding, etc., and the output end of the first driving member 1321 is transmission-connected with the first clamping plate 1322 and / or the second clamping plate 1323 to drive the first clamping plate 1322 and / or the second clamping plate 1323 to move, and is used to adjust the distance between the first clamping plate 1322 and the second clamping plate 1323. When the clamping assembly 132 needs to grab the rivet at the material picking station, or the clamping assembly 132 needs to release the rivet at the welding station, the distance between the first clamp plate 1322 and the second clamp plate 1323 needs to be adjusted to a larger distance. At this time, the first clamp plate 1322 can be driven by the first driving member 1321 to move in a direction away from the second clamp plate 1323, or the first driving member 1321 can drive the second clamp plate 1323 to move in a direction away from the first clamp plate 1322, or the first driving member 1321 can simultaneously drive the first clamp plate 1322 and the second clamp plate 1323 to move in directions away from each other, so that the rivet can enter the gap between the first clamp plate 1322 and the second clamp plate 1323 and be grabbed by the first clamp plate 1322 and the second clamp plate 1323. When the rivet needs to be transported from the material picking station to the welding station for welding, the distance between the first clamping plate 1322 and the second clamping plate 1323 needs to be adjusted to a smaller value. At this time, the first driving member 1321 can be used to drive the first clamping plate 1322 to move toward the direction close to the second clamping plate 1323, or the first driving member 1321 can be used to drive the second clamping plate 1323 to move toward the direction close to the first clamping plate 1322, or the first driving member 1321 can simultaneously drive the first clamping plate 1322 and the second clamping plate 1323 to move toward each other, so that the rivet can be clamped and fixed by the first clamping plate 1322 and the second clamping plate 1323, and transported from the material picking station to the welding station by the clamping assembly 132.

[0050] Of course, the clamping assembly 132 is not limited to the combination of the first driving member 1321, the first clamping plate 1322 and the second clamping plate 1323 provided above. The clamping assembly 132 can also be a combination of the first driving member 1321 and the mechanical clamping claw, the first driving member 1321 is in transmission connection with the mechanical clamping claw, and the first driving member 1321 drives the opening and closing of the mechanical clamping claw to grasp and release the rivet buckle. Among them, the specific structure of the mechanical clamping claw is the same as that of the prior art, and will not be described in detail here.

[0051] In order to weld the rivet buckle to the hoop, a preferred embodiment is as follows: Figure 1 and Figure 2 As shown, the welding assembly 133 includes a transformer 1331 and a welding clamp 1332. The transformer 1331 is arranged on the welding clamp body 131 by screw connection, welding, etc., and the welding clamp 1332 is also arranged on the welding clamp body 131 by screw connection, welding, etc., so as to realize the installation connection between the transformer 1331 and the welding clamp 1332, and the welding clamp 1332 is electrically connected to the transformer 1331. When the rivet buckle needs to be welded to the hoop at the welding station, the transformer 1331 reduces the voltage and provides a large welding current, and the welding clamp 1332 can conduct the welding current provided by the transformer 1331 to ensure the current density of the welding point at the end of the welding clamp 1332, so that the contact surface of the rivet buckle and the hoop is thermally melted, thereby welding the rivet buckle to the hoop, and completing the welding operation of the rivet buckle on the hoop.

[0052] In order to weld rivets at different positions of the hoop, a preferred embodiment is as follows: Figure 1 and Figure 2 As shown, the welding mechanism 130 also includes a rotating assembly 134. The rotating assembly 134 is arranged on the frame 110, and the output end of the rotating assembly 134 is connected to the welding clamp body 131 in a transmission manner. Since the number of rivet buckles welded on a hoop is not limited to one, more often, multiple rivet buckles need to be welded on the same hoop to improve the reliability of the connection between the hoop and other structural parts (such as cage reinforcement, etc.), the position of the welding surface of the rivet buckle can be adjusted by the rotating assembly 134 to adjust the welding surface of the rivet buckle to a position opposite to the welding surface of the corresponding hoop, thereby completing the welding operation of the rivet buckle and the hoop. For example, in this embodiment, when it is necessary to weld rivet buckles on all four inner walls of the hoop, the welding clamp body 131 can be rotated by the rotating assembly 134, and the welding clamp body 131 drives the clamping assembly 132 and the welding assembly 133 to rotate, so that the welding surface of the rivet buckle is opposite to the welding surface of the corresponding hoop, and the welding surface of the rivet buckle can be welded to the welding surface of the hoop as a whole by the welding clamp 1332, so as to weld the rivet buckle at different positions of the hoop.

[0053] Specifically, Figure 1 and Figure 2As shown, the rotating assembly 134 includes a second driving member 1341 and a gear set 1342 meshing with each other. The second driving member 1341 is directly or indirectly arranged on the frame 110 by screw connection, welding, etc., one of the gears in the gear set 1342 is drivingly connected to the output end of the second driving member 1341, and the output shaft of another gear in the gear set 1342 is drivingly connected to the welding clamp body 131. When the welding surface of the rivet buckle needs to be adjusted, the second driving member 1341 outputs power to one of the gears in the gear set 1342 to drive the gear to rotate, and the gear drives another gear meshing with it to rotate, and the other gear outputs the rotational force to the welding clamp body 131 to adjust the orientation of the welding clamp body 131. Since the clamping assembly 132 and the welding assembly 133 are both fixed on the welding clamp body 131, during the rotation of the welding clamp body 131, the clamping assembly 132 and the welding assembly 133 rotate with it to adjust the welding surface of the rivet buckle to a position relative to the welding surface of the corresponding ferrule, thereby facilitating the welding operation of the rivet buckle and the ferrule.

[0054] In order to drive the welding mechanism 130 to move between the material taking station and the welding station, a preferred embodiment is as follows: Figure 1 , Figure 4 as well as Figure 5 As shown, the welding mechanism 130 further includes an X-direction driving assembly 135, a Y-direction driving assembly 136, and a Z-direction driving assembly 137. In this embodiment, the work surface (such as the mounting surface of the rivet welding device 100) is taken as the reference plane, the X-direction and the Y-direction are both located in a plane parallel to the reference plane, the Z-direction is a direction perpendicular to the reference plane, and the X-direction, the Y-direction, and the Z-direction are perpendicular to each other.

[0055] The X-axis driving assembly 135 includes a third driving member 1351, a first slide rail 1352, and a first moving plate 1353. The first moving plate 1353 is movably disposed on the first slide rail 1352, that is, the first moving plate 1353 is connected to the first slide rail 1352, and the first moving plate 1353 is slidable on the first slide rail 1352. The third driving member 1351 is directly or indirectly disposed on the frame 110 by means of screw connection, welding, etc., the output end of the third driving member 1351 is transmission-connected with the first moving plate 1353, and the first slide rail 1352 is fixed to the frame 110 by means of screw connection, welding, etc., so as to connect the X-axis driving assembly 135 to the frame 110. When the welding mechanism 130 needs to move along the X direction, the third driving member 1351 performs a corresponding action, and the third driving member 1351 outputs power to the first movable plate 1353, and the first movable plate 1353 moves along the X direction on the first slide rail 1352, thereby driving the welding mechanism 130 to move along the X direction on the frame 110.

[0056] Correspondingly, the Y-axis driving assembly 136 includes a fourth driving member 1361, a second slide rail 1362 and a second movable plate 1363. The second movable plate 1363 is movably disposed on the second slide rail 1362, that is, the second movable plate 1363 is connected to the second slide rail 1362, and the second movable plate 1363 is slidable on the second slide rail 1362. The fourth driving member 1361 is directly or indirectly disposed on the frame 110 by screwing, welding, etc., the output end of the fourth driving member 1361 is transmission-connected with the second movable plate 1363, and the second slide rail 1362 is fixed to the first movable plate 1353 by screwing, welding, etc., so as to connect the Y-axis driving assembly 136 to the X-axis driving assembly 135, and indirectly connected to the frame 110 through the X-axis driving assembly 135. When the welding mechanism 130 needs to move along the Y direction, the fourth driving member 1361 performs a corresponding action, and the fourth driving member 1361 outputs power to the second movable plate 1363, and the second movable plate 1363 moves along the Y direction on the second slide rail 1362, thereby driving the welding mechanism 130 to move along the Y direction on the frame 110.

[0057] Similarly, the Z-axis driving assembly 137 includes a fifth driving member 1371, a third slide rail 1372 and a third movable plate 1373. The third movable plate 1373 is movably disposed on the third slide rail 1372, that is, the third movable plate 1373 is connected to the third slide rail 1372 and is slidable on the third slide rail 1372. The fifth driving member 1371 is directly or indirectly arranged on the frame 110 by means of screw connection, welding, etc., and the output end of the fifth driving member 1371 is transmission connected to the third movable plate 1373. The third slide rail 1372 is fixed to the second movable plate 1363 by means of screw connection, welding, etc. to connect the Z-axis driving assembly 137 to the Y-axis driving assembly 136, and is indirectly connected to the frame 110 through the X-axis driving assembly 135 and the Y-axis driving assembly 136. The welding clamp body 131 is fixed on the third movable plate 1373. Since the clamping assembly 132 and the welding assembly 133 are both fixed on the welding clamp body 131, when the third movable plate 1373 moves on the third slide rail 1372, the clamping assembly 132 and the welding assembly 133 can be driven to move along the Z direction on the third slide rail 1372. When the welding mechanism 130 needs to move along the Z direction, the fifth driving member 1371 performs a corresponding action, and the fifth driving member 1371 outputs power to the third movable plate 1373, and the third movable plate 1373 moves along the Z direction on the third slide rail 1372, thereby driving the welding mechanism 130 to move along the Z direction on the frame 110.

[0058] The above-mentioned rivet welding device 100, through the linkage cooperation of the X-axis drive component 135, the Y-axis drive component 136 and the Z-axis drive component 137, can drive the welding mechanism 130 to move in three-dimensional space, that is, to move along the X-axis, Y-axis and Z-axis on the frame 110, so that the welding mechanism 130 can move between the material picking station and the welding station, so as to realize that the clamping component 132 can grab the rivet when it moves to the material picking station, the clamping component 132 can release the rivet when it moves to the welding station, and the welding component 133 can weld the rivet when it moves to the welding station.

[0059] Furthermore, if Figure 1 , Figure 6 as well as Figure 7 As shown, the feeding mechanism 120 includes a feeding rack 121, a pushing assembly 122 and a storage rod 123. The feeding rack 121 is fixed to the frame 110 by screwing, welding, etc., and the storage rod 123 is also fixed to the feeding rack 121 by screwing, welding, etc. The feeding rack 121 has a storage cavity 1231, and the storage cavity 1231 can be used for storing multiple rivet buckles, avoiding the need to frequently add materials to the rivet buckles, and improving the welding efficiency of the rivet buckles on the hoop. The storage rod 123 extends in a direction perpendicular to the fixed surface of the storage rod 123. In the present embodiment, the overall shape of the storage rod 123 is rod-shaped, and the storage rod 123 is vertically fixed to the feeding rack 121. The pusher assembly 122 is provided with a clamping groove 1223, and the opening of the clamping groove 1223 faces the storage rod 123. Since the storage rod 123 is vertically fixed on the feeding rack 121, under the action of gravity or external force such as elastic force, the rivets stored in the storage cavity 1231 can freely fall into the clamping groove 1223, and the clamping groove 1223 can receive the rivets dropped from the storage rod 123. The pusher assembly 122 is fixed to the feeding rack 121 by screw connection, welding, etc. The pusher assembly 122 is used to push the rivets received on the clamping groove 1223 to the material taking station to complete the feeding operation of the rivets, and facilitate the welding mechanism 130 to grab the rivets at the material taking station.

[0060] In order to realize intermittent feeding of rivet buttons, specifically, Figure 1 , Figure 6 as well as Figure 7As shown, the feeding mechanism 120 also includes a baffle plate 124. The baffle plate 124 is arranged at a relative interval with the feeding rack 121, and a feeding hole 125 is formed between the baffle plate 124 and the feeding rack 121, and the feeding hole 125 is located between the storage rod 123 and the material taking station. Since a large number of rivets are stored in the storage rod 123, under the action of gravity or external forces such as elastic force, a large number of rivets will fall freely in a concentrated manner. Due to the existence of the feeding hole 125, the baffle plate 124 can block other rivets that do not need to be pushed to the material taking station, and allow the rivets that need to be moved to the material taking station to be sent to the material taking station through the feeding hole 125, that is, the pushing assembly 122 can only push one rivet through the feeding hole 125 and send it to the material taking station in a single movement, which is convenient for the welding mechanism 130 to grasp the rivets at the material taking station, and realize the intermittent feeding of the rivets.

[0061] In addition, if Figure 1 , Figure 6 as well as Figure 7 As shown, the push assembly 122 includes a sixth driving member 1221 and a push rod 1222. The sixth driving member 1221 is directly or indirectly arranged on the feed rack 121 by screw connection, welding, etc., and the output end of the sixth driving member 1221 is transmission-connected with the push rod 1222. In this embodiment, the overall shape of the push rod 1222 is rod-shaped, and the push rod 1222 is horizontally fixed on the feed rack 121, and the clamping groove 1223 is provided on the push rod 1222. When the sixth driving member 1221 is actuated, the push rod 1222 can be driven to move in a horizontal direction, and the rivet button received in the clamping groove 1223 can be pushed to the material taking station, so as to prepare for the rivet button grabbing operation of the welding mechanism 130. Among them, the sixth driving member 1221 can be one of a pneumatic element or an electric element. For example, if the sixth driving member 1221 is a pneumatic component, the sixth driving member 1221 is a cylinder, which is fixed to the feeding frame 121 by screwing, welding, etc., and the push rod 1222 is connected to the output shaft of the cylinder. When the cylinder is actuated, the cylinder can drive the push rod 1222 to move in the horizontal direction. If the sixth driving member 1221 is an electric component, the user can set it specifically according to the component type.

[0062] In order to further facilitate the welding mechanism 130 to grasp the rivet buckle, specifically, Figure 1 , Figure 6 as well as Figure 7As shown, the feeding mechanism 120 further includes a flip member 126, which is rotatably connected to the feeding frame 121. In this embodiment, the cross section of the push rod 1222 in a direction perpendicular to its extension direction is triangular. When the push rod 1222 pushes the rivet button to the material taking station, the rivet button can be tilted and overlapped in the clamping groove 1223 provided on the push rod 1222. When the push rod 1222 moves along the X direction, the rivet button and the push rod 1222 move to the material taking station, so that the welding mechanism 130 can grab the rivet button. A picking portion 1261 is provided on the flip member 126. When the push rod 1222 pushes the rivet button to the picking station, the picking portion 1261 can absorb and grab the rivet button, and by rotating the flip member 126 on the feeding rack 121, the angle of the rivet button can be adjusted to a position that is easily grabbed by the welding mechanism 130, thereby further facilitating the welding mechanism 130 to grab the rivet button.

[0063] It should be noted that the cross section of the push rod 1222 in the direction perpendicular to its extension direction is not limited to the triangle provided above, and can also be a quadrilateral or other polygon. The present invention does not limit the specific shape of the cross section of the push rod 1222, and can be set according to the specific process. In this embodiment, a magnetic element is provided at the end of the flip member 126 to form a material-collecting portion 1261. Since the rivet buckle is magnetic, the rivet buckle can be quickly adsorbed and grasped under the magnetic effect of the magnetic element, thereby improving the welding efficiency of the rivet buckle. Of course, in other embodiments, other elements such as buckles and splints that can grasp the rivet buckle can also be provided at the end of the flip member 126. The present invention does not limit how to set the material-collecting portion 1261 on the flip member 126.

[0064] In order to transport the ferrule to the welding station for welding operation, a preferred embodiment is as follows: Figure 1 and Figure 8 As shown, the conveying mechanism 140 includes a conveying frame 141, a clamping member 142 and a plurality of rollers 143. The plurality of rollers 143 are rotatably arranged on the conveying frame 141, and the conveying frame 141 is spaced apart from the frame 110. In this embodiment, the conveying frame 141 and the frame 110 are both fixed on a work surface (such as the floor of the operating area), and there is a gap between the conveying frame 141 and the frame 110 for the conveyance and passage of the hoop. During the rotation of the roller 143, the roller 143 can convey the hoop to the welding station, and when the hoop arrives at the welding station, the clamping member 142 can fix the hoop to prevent the hoop from rotating or shifting in position during the welding process, which affects the welding position and welding quality of the rivet on the hoop.

[0065] The clamping member 142 may be a plurality of movable baffles disposed on the frame 110. When the ferrule reaches a predetermined welding position, the movable baffles are moved to clamp the ferrule so as to fix the ferrule on the welding station. Of course, in other embodiments, the clamping member 142 may also be a snap-fit ​​member or a magnetic member, which fixes the ferrule on the welding station by snapping or magnetic connection to prevent the ferrule from rotating or shifting in position during the welding process.

[0066] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
