Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a hot riveting welding equipment for ship steel structure processing. Background Technology

[0002] The development of hot riveting and welding equipment for ship steel structure fabrication stems from the urgent need for efficient, reliable, and low-deformation connection processes brought about by the increasing size of ships, the demand for higher-strength materials, and the extreme service environments. It aims to overcome the key drawbacks of traditional cold riveting, such as low efficiency and high labor intensity, as well as the large heat-affected zone, residual stress, and severe deformation associated with conventional arc welding. By combining localized heating, plastic deformation (upsetting), and metallurgical bonding (welding), hot riveting and welding technology offers a superior solution for high-strength thick plate connections, critical load-bearing components, and fatigue- and impact-resistant parts, making it an important component of modern advanced shipbuilding technology. The design and manufacture of specialized equipment (such as automated hot riveting and welding machines) are specifically designed to achieve this advanced process efficiently, stably, and reliably.

[0003] Hot riveting welding mainly relies on manual operation, and the quality is difficult to guarantee. At the same time, it is difficult to move and accurately position in complex spaces such as narrow cabins, curved surfaces or high altitudes on ships. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a hot riveting and welding equipment for processing ship steel structures, comprising a main support, a heating device fixedly connected to the side of the main support, a pressing device fixedly connected to the side of the main support away from the heating device, and a moving device fixedly connected to the portion of the main support located on the side of the heating device. The heating device includes a lower base plate with an arc-shaped sliding hole at its top. An upper top plate is rotatably connected to the top of the lower base plate, and a straight sliding hole is located at its top. A driven gear ring is located on the side of the upper top plate, and an electric gear meshes with the side of the driven gear ring. The bottom of the electric gear is fixedly connected to the side of the lower base plate via a bracket. A heating element is slidably connected to the inner wall of the straight sliding hole. The side of the lower base plate is fixedly connected to the side of the main bracket. When the electric gear is activated, its rotation drives the driven gear ring to rotate, which in turn drives the heating element to rotate along the straight sliding hole. The electric gear is fixed to the side of the lower base plate via the bracket, causing the lower base plate and the upper top plate to rotate relative to each other. This allows the heating element to slide along the inner walls of the arc-shaped and straight sliding holes, enabling the synchronous movement of multiple heating elements to simultaneously fix the rivet at multiple angles. The heating elements also heat the rivet, facilitating riveting.

[0005] Preferably, the heating assembly includes a sliding seat, a straight slide bar fixedly connected to the bottom of the sliding seat, a limiting cylinder communicating with the bottom of the sliding seat, a limiting ring sleeved and fixedly connected to the bottom side of the limiting cylinder, a heating assembly fixedly connected to the top of the sliding seat, a support assembly fixedly connected to the bottom of the limiting ring, the sliding seat being slidably connected to the top of the upper plate via the straight slide bar, and the limiting ring extending into the inner wall of the arc-shaped sliding hole and slidably connected to the inner wall of the arc-shaped sliding hole.

[0006] Preferably, the heating component includes a sliding ring, a limiting rod slidably connected to the inner wall of the sliding ring, a fixing groove formed on the side of the limiting rod, a semi-circular bracket fixedly connected to the top of the side of the fixing groove, a rotating ball rotatably connected to the top of the semi-circular bracket, an upper connecting rod fixedly connected to the bottom of the limiting rod, the bottom of the sliding ring fixedly connected to the top of the sliding seat, the limiting rod penetrating the top of the sliding seat and slidably connected to the sliding seat, and the bottom of the upper connecting rod fixedly connected to the top of the support component.

[0007] Preferably, the support assembly includes a sliding housing with a through hole at the bottom of its inner wall. A spring is fixedly connected to the bottom of the inner wall of the sliding housing, and a sliding base is fixedly connected to the top of the spring. A lower connecting rod is passed through and fixedly connected to the top of the sliding base. The top of the lower connecting rod is fixedly connected to the bottom of the upper connecting rod. The top of the sliding housing is fixedly connected to the bottom of the limiting ring. When the arc-shaped sliding hole and the straight sliding hole work together to compress the limiting cylinder and the limiting ring, the limiting cylinder drives the sliding seat to slide. The straight sliding bar limits the pointing angle of the sliding seat at the top of the upper plate. The sliding seat drives the sliding ring to move, and the movement of the sliding ring drives the limiting rod to move. The movement of the limiting rod compresses the side of the rivet, thereby positioning the rivet and, through the upper connecting rod... The limiting rod is powered and heated, which in turn heats the rivet, facilitating subsequent extrusion deformation. When the through hole approaches the side of the rotating ball, the surrounding area of ​​the through hole compresses the rotating ball, causing it to move. The semi-circular bracket moves the limiting rod downwards, which slides along the inner wall of the sliding ring. This movement, via the upper connecting rod, moves the lower connecting rod, which in turn moves the sliding base, compressing the spring and generating an upward elastic force that brings the top of the rotating ball into contact with the surface around the through hole. This stabilizes the rivet and facilitates alignment with the through hole. Furthermore, the rotating design of the rotating ball and the semi-circular bracket allows for easy movement of the rotating ball, facilitating alignment and the extrusion welding of the rivet.

[0008] Preferably, the extrusion device includes a hydraulic cylinder, a push piston is slidably connected to the inner wall of the hydraulic cylinder, a screw is fixedly connected to the side of the push piston, a drive gear is sleeved and threadedly connected to the side of the screw, an electric worm gear meshes with the top of the drive gear, the side of the electric worm gear is fixedly connected to the side of the hydraulic cylinder through a bracket, a fixing plate is fixedly connected to the side of the hydraulic cylinder away from the drive gear, an extrusion assembly is penetrated and fixedly connected to the side of the fixing plate, the side of the extrusion assembly communicates with the side of the hydraulic cylinder, and the side of the fixing plate is fixedly connected to the side of the main bracket.

[0009] Preferably, the extrusion assembly includes a sliding cylinder, an arc-shaped slide bar fixedly connected to the inner wall of the sliding cylinder, a sliding piston slidably connected to the inner wall of the sliding cylinder, a connecting rod fixedly connected to the side of the sliding piston, an extrusion base fixedly connected to the side of the connecting rod, a positioning groove provided on the side of the extrusion base, the side of the sliding cylinder communicating with the side of the hydraulic cylinder, and a positioning groove adapted to the positioning groove provided on the side of the upper top plate. When the electric worm gear is activated, its rotation drives the drive gear to rotate, which in turn drives the screw to move. The screw's movement drives the piston to move, which in turn pushes the hydraulic oil inside the hydraulic cylinder, thereby allowing the hydraulic oil to enter the sliding cylinder. The internal mechanism pushes the sliding piston to move, and during the movement of the sliding piston, it slides along the arc-shaped slide bar. This causes the sliding piston to drive the connecting rod to rotate during the movement. The rotation of the connecting rod drives the extrusion base to rotate, thereby rotating and extruding the side of the rivet. This facilitates the extrusion and riveting process, and the rotation process helps the rivet to rotate, thus filling the area around the through hole and increasing the stability of the riveting. Through the continuous unidirectional transmission of the electric worm gear, drive gear, and screw, the rivet is kept in a fixed position after being extruded to the appropriate position, thus preventing the riveting from failing due to thermal deformation.

[0010] Preferably, the mobile device includes a mobile support, a mobile base fixedly connected to the bottom of the mobile support, a rubber roller rotatably connected to one side of the bottom of the mobile base via a pivot, and a magnetic roller rotatably connected to the side of the bottom of the mobile base away from the rubber roller via a pivot. The side of the mobile support is fixedly connected to the side of the main support. The mobile support supports the main support, and the mobile base supports the rubber roller and the magnetic roller. The support of the rubber roller facilitates the movement of the main support, and the magnetic force of the magnetic roller attracts the surface of the steel structure, thereby facilitating stable operation of the equipment and improving its stability.

[0011] This invention provides a hot riveting and welding device for ship steel structure processing. It has the following advantages: 1. The hot riveting and welding equipment for ship steel structure processing is equipped with an electric gear. The rotation of the electric gear drives the driven gear ring to rotate, and the rotation of the driven gear ring drives the heating component to rotate along the straight sliding hole. The electric gear is fixed to the side of the lower bottom plate through a bracket, so that the lower bottom plate and the upper top plate rotate relative to each other. This causes the heating component to slide along the inner wall of the arc-shaped sliding hole and the straight sliding hole, thereby realizing the synchronous movement of multiple sets of heating components, so as to simultaneously fix the rivets at multiple angles, and heat the rivets through the heating components, thereby facilitating riveting.

[0012] 2. The hot riveting and welding equipment used for ship steel structure processing is equipped with arc-shaped sliding holes and straight sliding holes. When the arc-shaped sliding holes and straight sliding holes work together to compress the limiting cylinder and the limiting ring, the limiting cylinder drives the sliding seat to slide. The straight sliding bar limits the pointing angle of the sliding seat at the top of the upper plate. The sliding seat drives the sliding ring to move, and the movement of the sliding ring drives the limiting bar to move. The movement of the limiting bar compresses the side of the rivet, thereby positioning the rivet. The limiting bar is powered by the upper connecting bar, thereby heating the limiting bar and the rivet, which facilitates the subsequent compression deformation of the rivet. When the through hole approaches rotation... When the ball is on its side, the area around the through hole compresses the rotating ball. The rotating ball drives the semi-circular bracket to move, which in turn drives the limiting rod to move downward. The limiting rod slides along the inner wall of the sliding ring and, through the upper connecting rod, drives the lower connecting rod to move. The lower connecting rod descends and drives the sliding base to move, thereby compressing the spring and generating an upward elastic force that causes the top of the rotating ball to contact the surface around the through hole. This helps stabilize the rivet's state and facilitates alignment with the through hole. Furthermore, the rotating design of the rotating ball and the semi-circular bracket facilitates the movement of the rotating ball, making alignment easier and thus facilitating the compression welding of the rivet.

[0013] 3. The hot riveting and welding equipment for ship steel structure processing is equipped with an electric worm gear. The rotation of the electric worm gear drives the rotation of the drive gear, which in turn drives the movement of the screw. The movement of the screw drives the movement of the piston, which in turn pushes the hydraulic oil inside the cylinder, causing the hydraulic oil to enter the interior of the sliding cylinder. This, in turn, pushes the sliding piston to move. During the movement of the sliding piston, it slides along the arc-shaped slide bar, causing the sliding piston to drive the connecting rod to rotate. The rotation of the connecting rod drives the extrusion base to rotate, thereby extruding and extruding the side of the rivet. This facilitates the extrusion and extrusion of the rivet during the extrusion and riveting process. The rotation process also helps the rivet to rotate, thus filling the perimeter of the through hole and increasing the stability of the riveting. The continuous unidirectional transmission of the electric worm gear, drive gear, and screw ensures that the rivet is held in a fixed position after being extruded to the appropriate position, thus preventing the rivet from thermally deforming and causing riveting failure.

[0014] 4. The hot riveting and welding equipment for ship steel structure processing is equipped with a movable support, which supports the main support. The movable base supports the rubber rollers and magnetic rollers. The rubber rollers facilitate the movement of the main support, and the magnetic force of the magnetic rollers attracts the surface of the steel structure, thus facilitating stable operation of the equipment and improving its stability.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-2 The present invention provides a technical solution: a hot riveting and welding equipment for processing ship steel structures, including a main support 1, a heating device 2 fixedly connected to the side of the main support 1, a pressing device 3 fixedly connected to the side of the main support 1 away from the heating device 2, and a moving device 4 fixedly connected to the portion of the main support 1 located on the side of the heating device 2.

[0019] The main support 1 provides overall support for the equipment. The heating device 2 fixes and heats the rivets, facilitating extrusion molding. Different sized rivets are fixed and heated through corresponding components, improving the equipment's versatility. The extrusion device 3 uses hydraulic propulsion to deform the rivets for welding. During extrusion molding, the rivets rotate, ensuring they are centered in the through hole, thus improving riveting quality. The moving device 4 moves the equipment as a whole, facilitating continuous operation on the same plane. The magnetic force provided by the moving device 4 increases the stability of the overall equipment and facilitates fixed riveting on a certain plane.

[0020] The heating device 2 includes a lower base plate 201, an arc-shaped sliding hole 202 on the top of the lower base plate 201, an upper top plate 203 rotatably connected to the top of the lower base plate 201, a straight sliding hole 204 on the top of the upper top plate 203, a driven gear ring 205 on the side of the upper top plate 203, an electric gear 206 meshing with the side of the driven gear ring 205, the bottom of the electric gear 206 being fixedly connected to the side of the lower base plate 201 via a bracket, a heating component 207 being slidably connected to the inner wall of the straight sliding hole 204, and the side of the lower base plate 201 being fixedly connected to the side of the main bracket 1.

[0021] When the electric gear 206 is activated, its rotation drives the driven gear ring 205 to rotate. The rotation of the driven gear ring 205 drives the heating component 207 to rotate along the straight sliding hole 204. The electric gear 206 is fixed to the side of the lower base plate 201 via a bracket, thereby causing the lower base plate 201 and the upper top plate 203 to rotate relative to each other. This causes the heating component 207 to slide along the inner walls of the arc-shaped sliding hole 202 and the straight sliding hole 204, thus achieving synchronous movement of multiple sets of heating components 207. This enables the rivet to be fixed at multiple angles simultaneously, and the rivet is heated by the heating component 207, facilitating riveting.

[0022] Please see Figures 1-5 The present invention provides a technical solution: the heating component 207 includes a sliding seat 2071, a straight slide bar 2072 is fixedly connected to the bottom of the sliding seat 2071, the bottom of the sliding seat 2071 is connected to a limiting cylinder 2073, a limiting ring 2074 is sleeved and fixedly connected to the bottom side of the limiting cylinder 2073, a heating component 2075 is fixedly connected to the top of the sliding seat 2071, a support component 2076 is fixedly connected to the bottom of the limiting ring 2074, the sliding seat 2071 is slidably connected to the top of the upper plate 203 through the straight slide bar 2072, and the limiting ring 2074 extends into the inner wall of the arc-shaped sliding hole 202 and is slidably connected to the inner wall of the arc-shaped sliding hole 202.

[0023] The heating component 2075 includes a sliding ring 20751. A limiting rod 20752 is slidably connected to the inner wall of the sliding ring 20751. A fixing groove 20753 is provided on the side of the limiting rod 20752. A semi-circular bracket 20754 is fixedly connected to the top of the side of the fixing groove 20753. A rotating ball 20755 is rotatably connected to the top of the semi-circular bracket 20754. An upper connecting rod 20756 is fixedly connected to the bottom of the limiting rod 20752. The bottom of the sliding ring 20751 is fixedly connected to the top of the sliding seat 2071. The limiting rod 20752 passes through the top of the sliding seat 2071 and is slidably connected to the sliding seat 2071. The bottom of the upper connecting rod 20756 is fixedly connected to the top of the support component 2076.

[0024] The support assembly 2076 includes a sliding housing 20761. A through hole 20762 is provided at the bottom of the inner wall of the sliding housing 20761. A spring 20763 is fixedly connected to the bottom of the inner wall of the sliding housing 20761. A sliding base 20764 is fixedly connected to the top of the spring 20763. A lower connecting rod 20765 is passed through and fixedly connected to the top of the sliding base 20764. The top of the lower connecting rod 20765 is fixedly connected to the bottom of the upper connecting rod 20756. The top of the sliding housing 20761 is fixedly connected to the bottom of the limiting ring 2074.

[0025] When the arc-shaped sliding hole 202 and the straight sliding hole 204 work together to compress and slide the limiting cylinder 2073 and the limiting ring 2074, the limiting cylinder 2073 drives the sliding seat 2071 to slide. The straight sliding strip 2072 restricts the pointing angle of the sliding seat 2071 at the top of the upper plate 203. The sliding seat 2071 drives the sliding ring 20751 to move. The movement of the sliding ring 20751 drives the limiting rod 20752 to move. The movement of the limiting rod 20752 compresses the side of the rivet, thereby positioning the rivet. The upper connecting rod 20756 supplies power to the limiting rod 20752, thereby heating the limiting rod 20752 and the rivet, which facilitates the subsequent compression deformation of the rivet. When the through hole approaches the side of the rotating ball 20755, the area around the through hole compresses the rotating ball 20755. 5. During compression, the rotating ball 20755 drives the semi-circular bracket 20754 to move. The semi-circular bracket 20754 drives the limiting rod 20752 to move downward. The limiting rod 20752 slides along the inner wall of the sliding ring 20751 and drives the lower connecting rod 20765 to move through the upper connecting rod 20756. The lower connecting rod 20765 descends and drives the sliding base 20764 to move, thereby compressing the spring 20763. This generates an upward elastic force that causes the top of the rotating ball 20755 to contact the surface around the through hole, which helps stabilize the rivet and facilitates alignment with the through hole. Furthermore, the rotational design of the rotating ball 20755 and the semi-circular bracket 20754 facilitates the movement of the rotating ball 20755, making alignment easier and thus facilitating the compression welding of the rivet.

[0027] The extrusion assembly 307 includes a sliding cylinder 3071, an arc-shaped slide bar 3072 fixedly connected to the inner wall of the sliding cylinder 3071, a sliding piston 3073 slidably connected to the inner wall of the sliding cylinder 3071, a connecting rod 3074 fixedly connected to the side of the sliding piston 3073, an extrusion base 3075 fixedly connected to the side of the connecting rod 3074, a positioning groove 3076 provided on the side of the extrusion base 3075, the side of the sliding cylinder 3071 communicating with the side of the hydraulic cylinder 301, and a positioning groove adapted to the positioning groove 3076 provided on the side of the upper top plate 203.

[0028] When the electric worm gear 305 is activated, its rotation drives the drive gear 304 to rotate, which in turn moves the screw 303. The screw 303's movement then moves the push piston 302, which in turn pushes the hydraulic oil inside the cylinder 301 into the sliding cylinder 3071. This, in turn, moves the sliding piston 3073, which slides along the arc-shaped slide bar 3072. This movement of the sliding piston 3073 then drives the connecting rod 3074 to move. During the process, the connecting rod 3074 is rotated, which in turn drives the extrusion base 3075 to rotate, thereby extruding and pressing the side of the rivet. This facilitates the extrusion and riveting process, and the rotation process helps the rivet to rotate, thus filling the area around the through hole and increasing the stability of the riveting. The continuous unidirectional transmission of the electric worm gear 305, drive gear 304, and screw 303 ensures that the rivet is held in a fixed position after being extruded to the appropriate position, thereby preventing the riveting from failing due to thermal deformation of the rivet.
