Description

Technical Field

[0001] The invention relates to the technical field of steel structure welding, and in particular to a steel structure grid welding ball and rod accurate positioning structure and an assembling method. Background Art

[0002] Steel structure is one of the main types of building structures, mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, large venues, high-rise buildings and other fields. Grid structure is a common steel structure, and spherical connection nodes are the most commonly used connection nodes in grid structure. Spherical connection nodes have good mechanical properties, a large range of connection angles, and a more beautiful appearance, so they have a wide range of applications. However, the appearance characteristics of the spherical node require precise positioning in multiple directions such as plane direction, elevation direction, and centripetal direction during installation to ensure the overall assembly accuracy and bearing capacity of the grid.

[0003] After searching, the patent with patent announcement number CN202211388147.3 discloses a precise positioning structure and assembly method for welding balls and rods of a steel structure grid. Although the device supports and limits the welding balls through the adjustable bracket installed on the top of the frame during use, the adjustable bracket itself is height-adjustable, which can achieve the effect of driving the welding balls to move in the direction perpendicular to the ground, thereby realizing the function of adjusting the actual elevation of the welding balls, eliminating the process of repeatedly cutting and grinding the metal pipes used to support the welding balls, which not only simplifies the installation steps, but also avoids the waste of materials caused by cutting and grinding, thereby achieving the purpose of the invention of improving the construction efficiency of the assembly process of the spherical connection nodes of the steel structure grid and reducing the material loss during the assembly process. However, the device can only adjust the height position of the welding balls when in use, and cannot adjust the position and angle of the rods to be welded to the welding balls. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a steel structure grid welding ball and rod accurate positioning structure and assembly method, which solves the problems raised in the background technology.

[0005] The solution of the present invention to solve the above technical problems is as follows:

[0006] A steel structure grid welding ball and rod accurate positioning structure, comprising a bottom plate, a cushion block is installed at the bottom end of the bottom plate, a support module and a ball rack are installed on the bottom plate, and rods and welding balls are placed on the bottom plate through the support module and the ball rack.

[0007] The bottom plate is provided with a connecting plate, the connecting plate is provided with a back plate, the back plate is installed with a lifting module, the lifting module is slidably installed with a supporting module, the bottom plate is provided with a ball rack through a vertical rod supporting frame, the ball rack is provided with a second limiting groove, the ball rack is provided with a limiting claw on the outer side of the second limiting groove, the limiting claw is provided with a first limiting groove, and the supporting module is welded on the side of the bottom plate where the ball rack is provided with the limiting claw through a column support;

[0008] The welding ball is installed on the ball rack through the first limiting groove on the ball rack through the second limiting groove and the limiting claw, and the ball rack is provided with a groove at the bottom end of the second limiting groove, an air channel is opened in the vertical rod, and the vertical rod is connected with the groove through the air channel, and a negative pressure pipe is provided at the bottom end of the bottom plate, and the negative pressure pipe passes through the bottom plate and is connected with the air channel, and the welding ball is fixed in the second limiting groove by adsorption through the groove and the air channel.

[0009] Based on the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the support modules fixed on the bottom plate by column welding and the lifting modules movably installed by the lifting modules are symmetrically distributed on the bottom plate.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The support modules fixed on the bottom plate by column welding provide a stable support foundation. This welding fixation method ensures the firmness of the support modules on the bottom plate and is not prone to displacement or shaking. The support modules installed movably by the lifting module can adjust the height as needed while maintaining a symmetrical distribution with the fixed support modules, thereby ensuring the balance and stability of the entire structure. In this structure, the fixed support modules and the movable support modules are symmetrically distributed on the bottom plate, so that the entire structure can be evenly distributed when subjected to force, avoiding structural deformation or damage caused by uneven force.

[0013] Furthermore, a motor is installed on the lifting module, a screw rod is installed on the output end of the motor, a slider is slidably installed on the screw rod, a support module is installed on the slider, the support module is provided with a base, a support block is rotatably installed on the base, a slot is provided on the support block, a positioning laser is installed on one side end face of the support block below the slot, and the docking position of the rod and the welding ball is positioned by the positioning laser.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The motor is used as a power source, and its output end is connected to the screw rod, which is driven to rotate by the rotation of the motor. The screw rod is a precision transmission element with a spiral thread groove on its surface. When the screw rod rotates, the thread groove matches the thread on the slider, thereby driving the slider to slide on the screw rod. The sliding distance of the slider is related to the rotation angle and pitch of the screw rod, so the sliding distance of the slider can be accurately controlled by controlling the rotation of the motor. A support module is installed on the slider, and the support module is provided with a base, and a support block is rotatably installed on the base. The support block is used to carry the rod and fix the rod through the slot. The support block can rotate relative to the base to adjust the position and angle of the rod. This design enables the rod to flexibly adapt to different welding requirements. A positioning laser is installed on one end face of the support block below the slot. The positioning laser is used to emit a laser beam to accurately locate the docking position of the rod and the welding ball. By observing the projection position of the laser beam on the rod and the welding ball, the relative position between them can be accurately adjusted to ensure the docking accuracy during welding.

[0016] Furthermore, the support block is provided with first fixing bolts on both sides of the slot, and the rod is locked and fixed in the slot by the first fixing bolts.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The slots provided on the support block are used to accommodate the rods, and their shapes and sizes match those of the rods to ensure that the rods can be stably placed in the slots. The first fixing bolts are installed on both sides of the support block located in the slots, and their function is to firmly lock the rods in the slots through the tightening force of the bolts. When the bolts are tightened, the clamping force generated by them will act on the rods, thereby preventing the rods from moving or shaking in the slots. The locking mechanism depends on the cooperation between the bolts and the nuts. When the bolts are rotated and tightened, the nuts will move downward along the threads of the bolts until they are in close contact with the support block. At this time, the clamping force of the bolts is transmitted to the support block through the nuts, and then acts on the rods to achieve locking and fixing of the rods. By locking the rods in the slots through the first fixing bolts, it can be ensured that the rods will not move or shake during the welding process, thereby improving the stability and accuracy of the welding. Since the design of the slots and the first fixing bolts has a certain degree of versatility, they can adapt to rods of different sizes and shapes. This adaptability enables the structure to be widely used in welding operations of various steel structure grids.

[0019] Furthermore, a rotating seat is provided at the bottom end of the support block, and the support block is rotatably mounted on the base via the rotating seat and is locked and fixed by a second fixing bolt.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The rotating seat is a device that allows a component to rotate within a certain range. In this structure, the rotating seat is designed at the bottom end of the support block to connect the support block and the base. The support block is connected to the base through the rotating seat at its bottom end, and this connection allows the support block to rotate within a certain angle range. The rotation of the support block is achieved by a bearing or similar mechanism inside the rotating seat, which can reduce friction and provide smooth rotational movement. When the support block is adjusted to the desired angle, the second fixing bolt is used to lock the support block to prevent it from accidentally rotating or moving during the welding process. The second fixing bolt is usually connected to the base or rotating seat by a thread. When the bolt is tightened, the clamping force generated by it will act on the support block, thereby firmly fixing it in the desired position. Through the design of the rotating seat, the support block can be flexibly rotated within a certain angle range to adapt to rods of different sizes and shapes and welding requirements. This flexibility improves the adaptability and efficiency of the welding operation, allowing the operator to more conveniently adjust the position and angle of the rod. When the support block is locked by the second fixing bolt, its position is reliably fixed and will not move due to vibration or impact during the welding process. This stability ensures the accuracy and safety of welding operations and reduces welding defects caused by unstable rod positions. Adjusting the angle and locking the support block is relatively simple. Just rotate the support block to the desired position and use the second fixing bolt to lock it. This operation method not only saves time, but also reduces the difficulty of operation, allowing operators to complete welding operations more easily.

[0023] S1. The base plate is installed on the ground through pads to ensure structural stability;

[0024] S2, the support module and the ball rack are respectively installed on the bottom plate, and are used to hold the rods and the welding balls;

[0025] S3, the lifting module drives the screw rod to rotate through the motor, so that the slider slides on the screw rod, thereby adjusting the height of the support module;

[0026] S4, the welding ball is placed in the second limiting groove of the ball rack, and the first limiting groove of the limiting claw further limits the position of the welding ball;

[0027] S5. The negative pressure pipe under the bottom plate is connected to the airway and the groove in the upright pole through the airway;

[0028] S6. When the negative pressure tube generates negative pressure, the welding ball is adsorbed and fixed in the second limiting groove to ensure stability during the welding process;

[0029] S7, the rod is placed in the slot of the bracket and is locked and fixed by a first fixing bolt;

[0030] S8, the support block is mounted on the base through a rotating seat, which can easily adjust the position and angle of the rod;

[0031] S9, after the adjustment is completed, tighten and fix it with the second fixing bolt;

[0032] S10, the positioning laser is installed on one side of the support block to locate the docking position between the rod and the welding ball to ensure the welding accuracy;

[0033] S11. After the precise positioning of the welding ball and the rod is completed, welding operation is performed;

[0034] S12. Since the position and angle of the welding ball and rod have been precisely adjusted, the welding process can be carried out more efficiently and accurately.

[0035] The present invention provides a steel structure grid welding ball and rod accurate positioning structure and assembly method. It has the following beneficial effects:

[0036] Through the combination of lifting module, support module and positioning laser, the position and angle of the rod and welding ball can be accurately adjusted to achieve high-precision docking. The positioning laser provides an intuitive positioning reference, which helps to reduce docking errors and improve welding quality.

[0037] The support block is mounted on the base through a rotating seat and can be locked and fixed by a second fixing bolt. This design allows the support block to easily adjust the position and angle of the rod, increasing the flexibility of the structure. The design of the support module and the lifting module allows the height and position to be adjusted according to actual needs, further enhancing the adjustability of the structure.

[0038] The bottom plate is installed through pads, which increases the stability of the structure and reduces errors caused by uneven ground or vibration. The welding ball is installed through the second limit groove on the ball rack and the first limit groove of the limit claw. At the same time, the negative pressure generated by the negative pressure tube is adsorbed and fixed through the airway and groove, ensuring the stability of the welding ball during the welding process.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] See also Figures 1 to 7 As shown, the embodiments provided by the present invention are:

[0052] Embodiment 1

[0053] A steel structure grid welding ball and rod precise positioning structure, comprising a bottom plate 4, a cushion block 5 is installed at the bottom end of the bottom plate 4, a support module 2 and a ball rack 3 are installed on the bottom plate 4, a rod 1 and a welding ball 301 are supported on the bottom plate 4 through the support module 2 and the ball rack 3, a connecting plate 7 is provided on the bottom plate 4, a back plate 6 is provided on the connecting plate 7, a lifting module 8 is installed on the back plate 6, a support module 2 is slidably installed on the lifting module 8, a motor 802 is installed on the lifting module 8, a screw rod 801 is installed at the output end of the motor 802, and the screw rod 801 is installed at the output end of the motor 802. 1 is slidably mounted with a slider 803, and a support module 2 is mounted on the slider 803. The support module 2 is provided with a base 204, and a support block 207 is rotatably mounted on the base 204. A rotating seat 203 is provided at the bottom end of the support block 207. The support block 207 is rotatably mounted on the base 204 through the rotating seat 203, and is locked and fixed by a second fixing bolt 202, so as to facilitate the adjustment of the position and angle of the rod 1 through the support block 207. The rotating seat 203 is a precise rotating connection device that allows the component to rotate flexibly within a certain range. In this structure, the rotating seat 203 is cleverly designed at the bottom end of the support block 207 to connect the support block 207 and the base 204. The support block 207 is precisely connected to the base 204 through the rotating seat 203 at its bottom end. This connection method enables the support block 207 to rotate flexibly within a certain angle range. The rotational movement of the support block 207 is achieved by a precision bearing or similar mechanism inside the rotating seat 203, which can significantly reduce friction and provide smooth rotational movement. When the support block 207 is adjusted to the desired angle, the second fixing bolt 202 is used to lock the support block 207 to prevent it from accidentally rotating or moving during the welding process. The second fixing bolt 202 is usually connected to the base 204 or the rotating seat 203 through a precision thread. When the bolt is tightened, the clamping force generated by it acts on the support block 207, thereby firmly fixing it in the desired position. Through the design of the rotating seat 203, the support block 207 can be flexibly rotated within a certain angle range to adapt to rods 1 of different sizes and shapes and welding requirements. This flexibility significantly improves the adaptability and efficiency of the welding operation, allowing the operator to more conveniently adjust the position and angle of the rod 1. When the support block 207 is locked by the second fixing bolt 202, its position is reliably fixed and will not move due to vibration or impact during the welding process. This stability ensures the accuracy and safety of the welding operation and effectively reduces welding defects caused by the unstable position of the rod 1. The angle adjustment and locking operation of the support block 207 are relatively simple. The support block 207 only needs to be rotated to a desired position and locked using the second fixing bolt 202 .This operation mode not only saves time, but also reduces the difficulty of operation, so that the operator can complete the welding operation more easily. A slot 206 is provided on the support block 207, and the first fixing bolts 201 are installed on both sides of the slot 206 of the support module 2. The rod 1 is locked and fixed in the slot 206 by the first fixing bolts 201. The slot 206 designed on the support block 207 matches the shape and size of the rod 1 to be welded to ensure that the rod 1 can be stably placed in the slot 206. The first fixing bolt 201 is installed on the support block 207 on both sides of the slot 206, and the rod 1 is firmly locked in the slot 206 by the tightening force of the bolt. When the bolt is tightened, the clamping force generated by it acts on the rod 1, effectively preventing the rod 1 from moving or shaking in the slot 206. The realization of the locking mechanism depends on the precise matching of the bolt and the nut. When the bolt is rotated and tightened, the nut moves accurately downward along the thread of the bolt until it is in close contact with the support block 207. At this time, the clamping force of the bolt is transmitted to the support block 207 through the nut, and then acts on the rod 1 to achieve a stable fixation of the rod 1. Through the locking effect of the first fixing bolt 201, it can be ensured that the rod 1 will not move or shake during the welding process, thereby improving the stability and accuracy of welding. Since the design of the slot 206 and the first fixing bolt 201 has a certain versatility, it can adapt to rods 1 of different sizes and shapes, so that the structure can be widely used in welding operations of various steel structure grids. A positioning laser 205 is installed on one end face of the support block 207 below the slot 206. The positioning laser 205 is used to locate the docking position of the rod 1 and the welding ball 301. The motor 802 is used as a driving source, and its output end is directly connected to the precision screw 801. The screw 801 is driven by the rotation of the motor 802 to rotate accurately. As a high-precision transmission element, the screw 801 is designed with a precise spiral thread groove on its surface. When the screw 801 rotates, the thread groove interacts with the matching thread on the slider 803, thereby driving the slider 803 to slide precisely on the screw 801. The sliding distance of the slider 803 is closely related to the rotation angle and pitch of the screw 801. Therefore, by accurately controlling the rotation of the motor 802, the sliding distance of the slider 803 can be precisely controlled. A support module 2 is installed on the slider 803, and the module includes a base 204, and a support block 207 is installed on the base 204 through a rotating mechanism. The support block 207 is used to carry the rod 1 to be welded and firmly fix the rod 1 through the slot 206. The support block 207 can rotate relative to the base 204, so as to achieve flexible adjustment of the position and angle of the rod 1 to meet different welding requirements. A positioning laser 205 is installed below the end face of one side of the support block 207, and the laser can emit a laser beam to accurately calibrate the docking position of the rod 1 and the welding ball 301.By observing the projection position of the laser beam on the rod 1 and the welding ball 301, the relative position between them can be accurately adjusted to ensure that the docking accuracy during welding meets the requirements. The ball rack 3 is supported by the vertical rod 305 on the bottom plate 4, and the ball rack 3 is provided with a second limiting groove 304. The ball rack 3 is provided with a limiting claw 302 on the outside of the second limiting groove 304, and the limiting claw 302 is provided with a first limiting groove 303. The support module 2 is welded on the side of the bottom plate 4 where the ball rack 3 is provided with the limiting claw 302 through the column support. The support module 2 fixed by the column welding on the bottom plate 4 and the lifting module 8 movably installed by the lifting module 8 are symmetrically distributed on the bottom plate 4. On the bottom plate 4, the column and the support module 2 are firmly connected by the precision welding process to form a stable support foundation. The welding fixation method ensures the high stability of the support module 2 on the bottom plate 4 and effectively prevents the occurrence of displacement and shaking. The support module 2 movably installed by the lifting module 8 can flexibly adjust the height according to actual needs, while maintaining a symmetrical layout with the fixed support module 2, thereby ensuring the balance and stability of the overall structure. In this structure, the fixed support module 2 and the movable support module 2 are precisely symmetrically distributed on the bottom plate 4, so that the structure can evenly disperse the force when subjected to force, effectively avoiding structural deformation or damage caused by uneven force distribution.

[0056] Embodiment 3

[0057] A method for assembling a steel structure grid welding ball and rod precise positioning structure, comprising the following steps:

[0058] S1, the base plate 4 is installed on the ground through the pad 5 to ensure the stability of the structure;

[0059] S2, the support module 2 and the ball rack 3 are respectively installed on the bottom plate 4, and are used to hold the rod 1 and the welding ball 301;

[0060] S3, the lifting module 8 drives the screw rod 801 to rotate through the motor 802, so that the slider 803 slides on the screw rod 801, thereby adjusting the height of the support module 2;

[0061] S4, the welding ball 301 is placed in the second limiting groove 304 of the ball rack 3, and the first limiting groove 303 of the limiting claw 302 further limits the position of the welding ball 301;

[0062] S5, the negative pressure pipe 9 below the bottom plate 4 is connected to the air channel 307 and the groove 306 in the vertical pole 305 through the air channel 307;

[0063] S6. When the negative pressure tube 9 generates negative pressure, the welding ball 301 is adsorbed and fixed in the second limiting groove 304 to ensure stability during the welding process;

[0064] S7, the rod 1 is placed in the slot 206 of the bracket 207 and is fastened and fixed by the first fixing bolt 201;

[0065] S8, the support block 207 is installed on the base 204 through the rotating seat 203, and the position and angle of the rod 1 can be easily adjusted;

[0066] S9, after the adjustment is completed, tighten and fix it with the second fixing bolt 202;

[0067] S10, the positioning laser 205 is installed on one side of the support block 207, and is used to locate the butt joint position between the rod 1 and the welding ball 301 to ensure welding accuracy;

[0068] S11, after completing the precise positioning of the welding ball 301 and the rod 1, the welding operation is performed;

[0069] S12. Since the positions and angles of the welding ball 301 and the rod 1 have been precisely adjusted, the welding process can be performed more efficiently and accurately.

[0070] Working principle:

[0071] The bottom plate 4 is firmly mounted on the ground via the pads 5 to ensure the static stability of the overall structure. The support module 2 and the ball rack 3 are precisely assembled on the bottom plate 4, the former is used to carry the rod 1, and the latter is used to support the welding ball 301. The working principle of the lifting module 8 relies on the motor 802 driving the rotation of the screw rod 801, prompting the slider 803 to slide along the axial direction of the screw rod 801, thereby realizing the precise adjustment of the height of the support module 2.

[0072] The welding ball 301 is precisely placed in the second limiting groove 304 of the ball rack 3, and its position is further constrained by the first limiting groove 303 of the limiting claw 302. The negative pressure pipe 9 under the bottom plate 4 and the internal air passage 307 and groove 306 of the vertical rod 305 form a sealed air path system. When the negative pressure pipe 9 is activated and produces a negative pressure effect, the welding ball 301 is firmly adsorbed in the second limiting groove 304, ensuring the position stability during the welding operation.

[0073] The rod 1 is properly placed in the slot 206 of the bracket 207 and is fastened and locked by the first fixing bolt 201. The bracket 207 is connected to the base 204 by means of the rotating seat 203, so that the position and angle of the rod 1 can be flexibly adjusted. After being adjusted in place, it is further locked by the second fixing bolt 202 to ensure stability. In addition, a positioning laser 205 is installed on one side of the bracket 207 to accurately indicate the docking position of the rod 1 and the welding ball 301 to ensure the accuracy of welding.

[0074] After the welding ball 301 and the rod 1 are precisely aligned, the welding operation is immediately performed. Since the position and angle of the welding ball 301 and the rod 1 have been precisely adjusted, the welding process can be performed efficiently and accurately.

[0075] The steel structure grid welding ball 301 and rod 1 precise positioning structure successfully achieves high-precision positioning and firm fixation of the welding ball 301 and rod 1 through the precise coordination of the lifting module 8, the support module 2, the ball rack 3, the support block 207 and the positioning laser 205. This structure not only significantly improves the accuracy and efficiency of welding, but also effectively reduces the complexity of operation and the error rate, providing solid technical support for the welding operation of the steel structure grid. At the same time, its modular design, high flexibility and adjustability enable the structure to easily adapt to rods 1 and welding balls 301 of different sizes and shapes, significantly enhancing its versatility and flexibility.
