Description

Technical Field

[0001] This utility model relates to the field of welding turntable technology, specifically a triangular stable welding support structure. Background Technology

[0002] The steering knuckle is one of the important components of the automotive braking system. Its main function is to connect the vehicle suspension and the brakes, and it also transmits braking torque, transmits vehicle steering force, and absorbs wheel impact. During the manufacturing process of the steering knuckle, the rear plate, upper plate, lower plate and longitudinal connecting plate of the steering knuckle bracket need to be welded together.

[0003] As disclosed in Chinese Patent CN219617019U, a welding turntable structure using a triangular bracket includes: a support platform; a base is installed on the inner side of the lower end of the support platform; a motor is installed inside the base; the output end of the motor passes through the base and the support platform; and the output end of the motor is connected to a platform plate. By installing a triangular bracket body at the lower end of the base, the triangular bracket body can support the position of the support platform through the base, effectively preventing the support platform and platform plate from shaking and affecting the welding work of the workpiece. The motor drives the platform plate to rotate, thereby adjusting the welding position.

[0004] However, the existing technology has the following drawbacks: the tripod body and the support are fixed, and the height of the support cannot be adjusted according to the user's height. The platform is rotated by a motor, and there is no limiting mechanism. When welding, it is impossible to keep the support from rotating, which is inconvenient to use.

[0005] Based on this, a triangular stable welded support structure is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0006] The purpose of this invention is to provide a triangular stable welded support structure to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A triangular stable welding support structure includes a fixed platform, the upper end of which is rotatably connected to a work platform. The fixed platform is equipped with a rotating mechanism that drives the work platform to rotate. The lower end of the fixed platform is equipped with a lifting component, which is connected to a first fixed block. The outer end of the first fixed block is fixedly connected to one end of three support rods. One end of a connecting rod is fixedly connected to the middle of the three support rods. The other end of the three connecting rods is fixedly connected to a second fixed block. The support rods are equipped with support members that support the fixed platform.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative embodiment: the rotating mechanism includes a rotating sleeve fixedly connected to the lower end of the work platform, a rotating column rotatably connected inside the rotating sleeve, the rotating column fixedly connected to the inner wall of the fixed platform, a worm gear fixedly connected to the outer end of the rotating sleeve, the worm gear meshing with a worm, the worm being rotatably connected to the fixed platform, the worm being fixedly connected to the output shaft of a first motor, and the first motor being fixedly connected to the fixed platform.

A threaded rod is threadedly connected to the inner wall of the fixed cylinder, and the threaded rod is fixedly connected to the output end of the second motor. The second motor is fixedly connected to the first fixed block.

[0010] In one alternative embodiment: the support member includes three support blocks, which are fixedly connected to the upper end of the support rod. Each support block has a groove, in which a sliding rod is slidably connected. The sliding rod is fixedly connected to the lower end of the fixed platform. The sliding rod has ratchet teeth that engage with a locking block. The locking block is fixedly connected to one end of a first rotating rod. The other end of the first rotating rod is fixedly connected to a first rotating block, which is rotatably connected to the inner wall of the groove. One end of a second rotating rod, perpendicular to the first rotating rod, is fixedly connected to the first rotating block. The other end of the second rotating rod is fixedly connected to one end of a spring, and the other end of the spring is fixedly connected to the support block.

[0011] In one alternative: a controller is fixedly connected to the side of the fixed platform, and the controller is electrically connected to motor one and motor two respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes the cooperation of a fixed cylinder, a threaded rod, and a second motor in the lifting component. The second motor drives the threaded rod to rotate, causing the fixed cylinder to move up and down, thereby achieving height adjustment between the fixed platform and the work platform. This adapts to the operating needs of users of different heights and improves work comfort. In the rotating mechanism, a first motor drives a worm gear to rotate, which in turn causes the work platform to rotate around a rotating column via a rotating sleeve, achieving flexible adjustment of the welding position. The self-locking property of the worm gear and worm wheel prevents the work platform from rotating during welding. Adjustable-length support components support the fixed platform from all sides to prevent tipping. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-4As shown, the triangular stable welding support structure includes a fixed platform 100, the upper end of which is rotatably connected to a working platform 200. The fixed platform 100 has a rotating mechanism that drives the working platform 200 to rotate. The lower end of the fixed platform 100 has a lifting component connected to a first fixed block 101. The outer end of the first fixed block 101 is fixedly connected to one end of three support rods 102. One end of a connecting rod 103 is fixedly connected to the middle of the three support rods 102. The other end of the three connecting rods 103 is fixedly connected to a second fixed block 104. The support rods 102 have support members that support the fixed platform 100. The three support rods 102, together with the first fixed block 101, the second fixed block 104, and the connecting rod 103, form a stable triangular structure that effectively resists deformation and overturning. The height of the fixed platform and the working platform can be adjusted using the lifting component to accommodate users of different heights. The steering knuckle is then placed on the working platform 200 for welding. The rotating mechanism rotates the working platform, allowing for flexible adjustment of the welding position.

[0023] In this embodiment, as Figure 2 and Figure 4 As shown, the rotating mechanism includes a rotating sleeve 301, which is fixedly connected to the lower end of the working platform 200. A rotating column 302 is rotatably connected inside the rotating sleeve 301, and the rotating column 302 is fixedly connected to the inner wall of the fixed platform 100. A worm gear 303 is fixedly connected to the outer end of the rotating sleeve 301, and the worm gear 303 meshes with a worm 304. The worm 304 is rotatably connected to the fixed platform 100. The worm 304 is fixedly connected to the output shaft of a motor 305, which is fixedly connected to the fixed platform 100. When the angle of the working platform 200 needs to be adjusted, the motor 305 is started, driving the worm 304 to rotate. The worm 304 drives the worm gear 303 and the rotating sleeve 301 to rotate, thereby realizing the rotation of the working platform 200. After rotating to a suitable angle, the motor 305 is turned off. The self-locking property of the worm and worm gear prevents the working platform from rotating during welding.

[0024] In one embodiment, such as Figure 2 As shown, the lifting component includes a fixed cylinder 401, which is fixedly connected to the lower end of the fixed platform 100. A threaded rod 402 is threadedly connected to the inner wall of the fixed cylinder 401. The threaded rod 402 is fixedly connected to the output end of a second motor 403. The second motor 403 is fixedly connected to a first fixed block 101. When the second motor 403 is started, it drives the threaded rod 402 to rotate. Due to the threaded engagement between the fixed cylinder 401 and the threaded rod 402, the fixed cylinder 401 will move up and down along the threaded rod 402, thereby driving the fixed platform 100 and the work platform 200 to rise and fall.

[0025] In one embodiment, such as Figure 3 As shown, the support component includes three support blocks 501, which are fixedly connected to the upper end of the support rod 102. Each support block 501 has a groove 502, in which a sliding rod 503 is slidably connected. The sliding rod 503 is fixedly connected to the lower end of the fixed platform 100. The sliding rod 503 has a ratchet 504, which engages with a locking block 505. The locking block 505 is fixedly connected to one end of a rotating rod 506, and the other end of the rotating rod 506 is fixedly connected to a first rotating block 507. The first rotating block 507 is rotatably connected to the inner wall of the groove 502. One end of a rotating rod 509, perpendicular to the first rotating rod 506, is fixedly connected to the moving block 507. The other end of the rotating rod 509 is fixedly connected to one end of a spring 508, and the other end of the spring 508 is fixedly connected to the support block 501. When the fixed platform 100 is raised or lowered, the sliding rod 503 slides in the groove 502, the locking block 505 slides along the surface of the ratchet 504, and the spring 508 is in a compressed state. When the fixed platform 100 stops raising or lowering, the spring 508 rebounds, and the second rotating rod 509 and the first rotating rod 506 drive the locking block 505 to engage in the groove of the ratchet 504, preventing the sliding rod 503 from moving and thus locking the height of the fixed platform 100.

[0026] In one embodiment, such as Figure 1 As shown, a controller 600 is fixedly connected to the side of the fixed platform 100. The controller 600 is electrically connected to motor 305 and motor 403 respectively. The controller 600 is equipped with a PLC control system, which is used to control the start and stop of motor 305 and motor 403 to adjust the welding position and the height of the working platform.

[0027] In one embodiment, such as Figure 1 As shown, the three support rods 102 are evenly distributed on the outer end of the fixing block 101. Based on the principle of the stability of triangles, the three evenly distributed support rods, the fixing block 1, the fixing block 2 and the connecting rod form a stable triangular structure. This structure can effectively resist deformation and overturning when subjected to external forces from different directions, such as collisions of workpieces during welding or unintentional touches by the operator.

[0028] In one embodiment, such as Figure 3 As shown, a C-shaped retaining ring 700 is rotatably connected to the support block 501. The C-shaped retaining ring 700 is connected to the rotating rod 509. When it is necessary to release the limit, rotate the C-shaped retaining ring 700 to lock the rotating rod 509, thereby driving the first rotating block 507 to rotate and disengaging the retaining block 505 from the ratchet 504, so that the height can be readjusted.

[0029] In one embodiment, such as Figure 2As shown, the end of the support rod 102 away from the fixed block 101 is fixedly connected to one end of the fixed rod 801, and the other end of the fixed rod 801 is fixedly connected to the universal ball 802. The outer end of the universal ball 802 is rotatably connected to the second rotating block 803, and the lower end of the second rotating block 803 is fixedly connected to the rubber pad 804. The rubber pad 804 increases the friction with the ground, and the universal ball 802 allows the second rotating block 803 to adapt to different ground angles, thereby enhancing the stability of the support.

[0030] The above embodiment discloses a triangular stable welded bracket structure, in which three support rods 102, fixed block one 101, fixed block two 104, and connecting rod 103 form a stable triangular structure, effectively resisting deformation and overturning. When users of different heights need to adjust the height, motor two 403 is started. Motor two 403 drives the threaded rod 402 to rotate. Since the fixed cylinder 401 is threadedly engaged with the threaded rod 402, the fixed cylinder 401 will move up and down along the threaded rod 402, thereby driving the fixed platform 100 and the work platform 200 to rise and fall. During the rising and falling process, the sliding rod 503 slides in the groove 502, the locking block 505 slides along the surface of the ratchet 504, and the spring 508 is in a compressed state. When the fixed platform 100 stops rising and falling, the spring 508 is in a compressed state. Spring 508 rebounds, and through rotating rod 2 509 and rotating rod 1 506, locking block 505 into the groove of ratchet 504, preventing sliding rod 503 from moving. Sliding rod 503 constantly supports fixed platform 100. When it is necessary to release the limit, rotate C-shaped retaining ring 700 to lock rotating rod 2 509, driving first rotating block 507 to rotate, causing locking block 505 to disengage from ratchet 504, and height can be readjusted. When it is necessary to adjust the angle of work platform 200, start motor 1 305 through controller 600. Motor 1 305 drives worm gear 304 to rotate, and worm gear 304 drives worm wheel 303 and rotating sleeve 301 to rotate, thereby realizing the rotation of work platform 200. After rotating to the appropriate angle, motor 1 305 is turned off.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
