Description
Technical Field
[0001] This utility model relates to the field of electric vehicle frame welding technology, and in particular to an electric vehicle frame welding device. Background Technology
[0002] Electric vehicle frame welding is a crucial step in the manufacturing process, directly affecting the frame's strength, durability, and overall safety.
[0003] Currently, welding robots are used to weld vehicle frames. The front end of the welding robot is equipped with a fixing platform for securing the frame. The operator first needs to fix the frame on the top of the fixing platform, which is equipped with a clamp for securing the frame. After clamping the clamp to the top of the frame, the welding robot is started. The operator can input the welding task in advance to realize the automatic welding of the welding robot. Finally, the welded frame can be taken out. Since the frame and the fixing platform are kept horizontal during the welding process, the operator needs to consider the welding of the bottom and sides of the frame when operating the welding robot. At the same time, the welding robot cannot be adjusted to the correct position when the frame is in a remote location, which requires the operator to repeatedly adjust the position and movement trajectory of the robot, as well as the fixing position of the frame. To address this, an electric vehicle frame welding device was designed. Utility Model Content
[0004] The purpose of this invention is to provide an electric vehicle frame welding device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric vehicle frame welding device, including a welding table, and further comprising:
[0006] A welding machine assembly, the welding machine assembly including a welding part disposed on the top of a welding table for welding a vehicle frame, and a rotating chassis disposed on the top of the welding table and at the end away from the welding part.
[0007] A connecting assembly includes a support platform disposed at the top of a rotating chassis. A sliding ring is rotatably connected to the top of the support platform. A connecting plate is disposed on the inner wall of the sliding ring. A fixing platform for fixing the frame is disposed on the inner wall of the connecting plate. An external gear ring for rotating the connecting plate is disposed at the end of the connecting plate away from the fixing platform. A connecting gear for rotating the external gear ring is engaged on the outer wall of the external gear ring.
[0008] Preferably, the welding section includes a welding robotic arm and a welding gun, the welding gun is disposed at the top end of the welding robotic arm, and the bottom end of the welding robotic arm is fixedly connected to the top end of the welding table.
[0009] Preferably, the inner wall of the support platform is provided with an annular groove, and the inner wall of the annular groove is slidably connected to the outer wall of the sliding ring.
[0010] Preferably, a hinge platform is provided on the inner wall of the connecting plate at the end away from the fixed platform, and a threaded rod is hinged to the top of the hinge platform.
[0011] Preferably, the outer wall of the threaded rod is threadedly connected to a fixing ring, and the top of the fixing platform is symmetrically arranged with multiple hinge plates in a horizontal direction.

[0014] The technical effects and advantages of this utility model are as follows:
[0015] This utility model utilizes a connecting component installed at the top of the welding table. When the operator is performing fixed welding on the frame, the operator needs to fix the frame on the top of the fixed table. Then, the operator can rotate the connecting gear, which meshes with the external gear ring, causing the external gear ring to rotate the connecting plate. As a result, the connecting plate slides and rotates on the top of the support table using a sliding ring. At this time, the connecting plate causes the fixed table and the frame to flip, allowing the frame to freely adjust its position through the rotation of the connecting gear. By adjusting the position, the welding robot arm can be easily moved to the welding point, facilitating the welding of the frame by the welding robot arm. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides, for example Figure 1-4 The electric vehicle frame welding equipment shown includes a welding table 1, and further includes:
[0023] The welding machine assembly includes a welding section 2 disposed at the top of the welding table 1, the welding section 2 being used for welding the vehicle frame, and a rotating chassis 3 disposed at the top of the welding table 1 and at the end furthest from the welding section 2.
[0024] The connecting assembly includes a support platform 301 disposed at the top of the rotating chassis 3. A sliding ring 401 is rotatably connected to the top of the support platform 301. A connecting plate 402 is disposed on the inner wall of the sliding ring 401. A fixing platform 503 for fixing the frame is disposed on the inner wall of the connecting plate 402. An external gear ring 6 for rotating the connecting plate 402 is disposed at the end of the connecting plate 402 away from the fixing platform 503. A connecting gear 601 for rotating the external gear ring 6 is meshed on the outer wall of the external gear ring 6.
[0025] It should be noted that the operator needs to thread the front end of the frame through the threaded rod 501 and fix the frame to the top of the fixed platform 503. After the frame is fixed, the operator can start the welding robot arm 201. The working principle of the welding robot arm 201 and the welding gun 202 is based on the welding body of the welding robot of model FD-B144. The operator can remotely control the welding through the controller carried by the welding robot arm 201, or input the movement steps in advance on the welding robot arm 201. The welding robot arm 201 then starts the welding gun 202 to weld the fixed frame. The operator can also start the motor 602. The motor 602 rotates the connecting gear 601 through the output end. The connecting gear 601 drives the external gear ring 6 to rotate through meshing. Finally, the external gear ring 6 drives the connecting plate 402 and the frame of the fixed platform 503 to flip, which makes it convenient for the operator to start the welding robot arm 201 to weld other parts of the frame.
[0026] Specifically, the welding unit 2 includes a welding robotic arm 201 and a welding gun 202. The welding gun 202 is located at the top of the welding robotic arm 201, and the bottom of the welding robotic arm 201 is fixedly connected to the top of the welding table 1.
[0027] It should be noted that the chassis of the welding robotic arm 201 is fixedly connected to the top of the welding table 1 and located at one end close to the support table 301. The welding robotic arm 201 is an automated control manipulator that achieves flexibility and diversity in the welding process through programming and is reprogrammable.
[0028] Specifically, the inner wall of the support platform 301 is provided with an annular groove 4, and the inner wall of the annular groove 4 is slidably connected to the outer wall of the sliding ring 401.
[0029] It should be noted that the annular groove 4 is set at the connection between the sliding ring 401 and the support platform 301. The sliding ring 401 can slide along the annular groove 4, and the sliding ring 401 drives the connecting plate 402 to achieve annular sliding.
[0030] Specifically, a hinge platform 5 is provided on the inner wall of the connecting plate 402 at the end away from the fixed platform 503. A threaded rod 501 is hinged to the top of the hinge platform 5. A fixing ring 502 is threaded through the outer wall of the threaded rod 501. Multiple hinge plates 505 are horizontally and symmetrically arranged on the top of the fixed platform 503. Multiple fixing grooves 504 are provided at the connection between the fixed platform 503 and the multiple hinge plates 505.
[0031] It should be noted that when the operator fixes the frame, the frame tube at the front end of the frame needs to be fitted onto the outer wall of the threaded rod 501. Then, the fixing ring 502 is threaded from the top of the threaded rod 501 to the top of the frame tube. The frame tube is fixed to the outer wall of the threaded rod 501 by the clamping of the hinge platform 5 and the fixing ring 502. The operator then uses the hinge platform 5 to rotate the frame tube along the threaded rod 501, rotating the frame body to the top of the fixing platform 503. The bottom end of the frame is then fitted onto the inner wall of the fixing groove 504 for fixation. The hinge plate 505 is then rotated to the top of the frame body through the hinge. Finally, multiple bolts are threaded through the fixing platform 503 and the top of the hinge plate 505 to achieve fixation.
[0032] Specifically, the end of the connecting plate 402 away from the sliding ring 401 is provided with multiple side baffles 403, and the side of the external toothed ring 6 near the support platform 301 is fixedly connected to the outer wall of one of the side baffles 403.
[0033] It should be noted that the side baffle 403 is fixed on both sides of the connecting plate 402. The connecting plate 402 can be stabilized by sliding on the top of the support platform 301 through the side baffle 403. The outer toothed ring 6 is fixed on the outer wall of the side baffle 403. When the connecting gear 601 meshes with the outer toothed ring 6 and rotates, the connecting gear 601 will drive the side baffle 403 and the connecting plate 402 to rotate, thereby realizing the sliding of the connecting plate 402.
[0034] Specifically, a motor 602 is provided at the top of the support platform 301 and at the end near the external gear ring 6. The output end of the motor 602 is fixedly connected to the end of the connecting gear 601 away from the side baffle 403.
[0035] It should be noted that when the operator needs to adjust the welding position of the frame, the motor 602 is started. The motor 602 rotates the connecting gear 601 through the output end. The connecting gear 601 drives the external gear ring 6 to rotate through meshing. The external gear ring 6 drives the side baffle 403 to rotate. The side baffle 403 drives the connecting plate 402 to rotate. The connecting plate 402 drives the frame of the fixed platform 503 to slide and flip. The welding angle is adjusted by flipping.
[0036] Working principle of this utility model:
[0037] The operation involves the operator threading the front end of the electric vehicle frame through the outer wall of the threaded rod 501, then threading the retaining ring 502 onto the top of the threaded rod 501. The retaining ring 502, through its threaded connection to the threaded rod 501, pushes against the front end of the frame, thus fixing the front end of the frame. Next, the threaded rod 501 is rotated vertically around the hinge platform 5, causing the frame to rotate to the top of the fixing platform 503. The bottom end of the frame can then be rotated and fitted onto the inner wall of the fixing groove 504. At this point, the operator needs to use the hinges to rotate multiple hinge plates 505 to the top of the outer wall of the frame, utilizing the hinge plates 505 and the fixing platform 503. The clamping mechanism 3 secures the frame body. Then, the motor 602 is started. The motor 602 rotates the connecting gear 601 through its output end. The connecting gear 601 drives the side baffle 403 and the connecting plate 402 to rotate through the meshing transmission external gear ring 6. The connecting plate 402 drives the fixed platform 503 and the hinge platform 5 to rotate, thereby driving the electric vehicle frame to rotate synchronously in the vertical direction. During the rotation, the sliding ring 401 connected to the connecting plate 402 rotates along the annular groove 4. The operator can rotate it to the appropriate position according to the welding part of the electric vehicle frame. Finally, the welding robot arm 201 drives the welding gun 202 to weld the electric vehicle frame.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
