Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing equipment, in particular to a turning device for welding an automobile seat frame. Background Art

[0002] In automobile manufacturing, the welding of seat frames is a key process step. The flipping device plays an important role in this process, and its main functions include optimizing the welding angle, improving operational efficiency and ensuring welding quality. Structurally, the flipping device usually includes a support platform, a flipping mechanism, a positioning device and a control system. The support platform provides a stable working platform, the flipping mechanism realizes the precise rotation of the seat frame through an electric drive or hydraulic system, and the positioning device ensures the stable position of the seat frame during welding, which together ensure the accuracy and efficiency of the welding process; such as the flipping device for welding automobile seat frames disclosed in the authorization announcement number CN218169258U, which includes a support frame, a rotating assembly and a bracket, wherein the bracket is provided with an L-shaped frame that can support and fix the L-shaped seat frame, and arc-shaped slides are provided on both sides of the frame, and arc-shaped grooves are provided on both sides of the support frame. The bracket is fixed to the rotating shaft of the rotating assembly and can rotate around the rotating shaft. The curved slides on both sides of the bracket can slide in the curved grooves on both sides of the support frame. The bracket drives the seat frame to flip and a pin can be used to prevent the bracket from flipping over on its own. The bracket is made into an L-shaped open frame, and the L-shaped seat frame fixed on it can be flipped but is not blocked on all sides. The welding gun is not only easier to weld the upper surface, vertical surface and end surface of the irregular L-shaped seat frame, but during the use of the above technical solution, the second sockets of the curved slides on both sides of the bracket and the first sockets of the curved grooves on the support frame are each connected with two pins to ensure the stability of the L-shaped open frame after the angle is adjusted. This requires the staff to frequently unlock and lock the frame during the welding process to meet the adjustable properties of the frame angle. Although the operation is simple, it will lead to low efficiency in seat frame welding in large-scale production, that is, each adjustment takes time and relies on manual operation of the operator. When multiple seat frames need to be adjusted frequently, the production progress is seriously delayed. Utility Model Content

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5 The present invention provides an embodiment of a welding turning device for a car seat frame, comprising a bottom frame 1 and right-angle beams 2 integrally formed on the two inner walls of the bottom frame 1, a U-shaped shaft bracket 3 fixed to the surface of the bottom frame 1 on one side of the right-angle beam 2, a rotating shaft 301 rotatably mounted inside the U-shaped shaft bracket 3, and a crossbeam 5 mounted on both ends of the rotating shaft 301 through a T-shaped connector, the T-shaped connector being a right-angle seat 4 fixed to both ends of the rotating shaft 301, the top end of the right-angle seat 4 being fixedly connected to the bottom end of the crossbeam 5;

[0019] A main hydraulic cylinder 6 is hinged to the back of the right-angle beam 2. The top of the piston rod of the main hydraulic cylinder 6 is hinged to the back of the crossbeam 5. A circular vertical plate 7 is fixed to both ends of the surface of the crossbeam 5. A hydraulic lifting mechanism 8 is mounted on the back of the circular vertical plate 7. The movable end of the hydraulic lifting mechanism 8 is mounted on the Z-shaped front frame 9. The surface of the Z-shaped front frame 9 is mounted with a hydraulic clamping mechanism 10 for clamping the seat frame.

[0020] The staff can arrange a control panel near the device to control the solenoid valves connected to the hydraulic cylinders of the device, and thus control the working status of each hydraulic cylinder;

[0021] An axle seat 501 is fixed to one end of the back of the crossbeam 5. The axle seat 501 and the top of the piston rod of the main hydraulic cylinder 6 are hinged to each other. When the main hydraulic cylinder 6 is extended, the piston rod end of the main hydraulic cylinder 6 drives the crossbeam 5, the right-angle seat 4 and other components to flip around the U-shaped axle frame 3 through the axle seat 501. The hydraulic system has high driving force and only requires simple button operation to complete complex seat frame adjustment and flipping movements, greatly simplifying the operation process.

[0022] The hydraulic clamping mechanism 10 includes a cylinder base 1001 fixed to the surface of the Z-shaped front frame 9, a hydraulic cylinder 2 1004 installed on the outer wall of one side of the cylinder base 1001, and a support plate 1002 fixed to the top of the piston rod of the hydraulic cylinder 2 1004. A clamping plate 1003 is installed on the outer wall of the support plate 1002 away from the cylinder base 1001. Guide rods are installed on both sides of the interior of the cylinder base 1001. One end of the guide rod is fixedly connected to the back of the support plate 1002. When the hydraulic clamping mechanism 10 is clamping the seat frame, the hydraulic cylinder 2 1004 drives the support plate 1002 and the clamping plate 1003 to move toward the direction of the center reference plane set on the bottom frame 1 until the two clamping plates 1003 are in contact with the outer wall of the seat frame at the same time, and the seat frame is clamped under the push of the hydraulic cylinder 2 1004, thereby achieving the purpose of fixing the seat frame;

[0023] The Z-shaped front frame 9 is slidably installed on the circular upright plate 7. The hydraulic lifting mechanism 8 includes a Z-axis hydraulic cylinder 801 installed on the back of the circular upright plate 7, and a connecting arm 802 fixed to the top of the piston rod of the Z-axis hydraulic cylinder 801. One end of the connecting arm 802 is fixedly connected to the back of the Z-shaped front frame 9. After the hydraulic clamping mechanism 10 fixes the seat, the Z-axis hydraulic cylinder 801 drives the Z-shaped front frame 9 to slide in the extension direction of the circular upright plate 7 through the connecting arm 802, thereby adjusting the height of the hydraulic clamping mechanism 10 and the seat frame to ensure that the welding operator can operate at the most comfortable working height.

[0024] When the embodiment of the present application is in use, the worker first lifts the automobile seat frame to be welded between the two hydraulic clamping mechanisms 10, and first controls the hydraulic clamping mechanisms 10 to operate, and the hydraulic clamping mechanisms 10 clamp and fix the automobile seat frame from both sides, thereby accurately clamping and fixing the seat frame to ensure that there is no position change or shaking during the welding process. After the automobile seat frame is clamped, the worker starts the main hydraulic cylinder 6 again to work. When the main hydraulic cylinder 6 actively extends, the crossbeam 5 and the right-angle seat 4 can be flipped around the rotating shaft 301 until the circular vertical plate 7, the crossbeam 5 and the clamped automobile seat frame and other components are flipped downward by ninety degrees. After the automobile seat frame is flipped and the welding process is completed, the main hydraulic cylinder 6 is retracted and reset, so that each component rotates in the original direction until it is reset, thereby realizing the automatic flipping function of the automobile seat frame, which reduces the operator's manual intervention and improves the accuracy and speed of flipping. During the welding operation, flipping at different angles allows the welding operator to approach the welding point more easily, thereby improving the accuracy and quality of welding and saving a lot of operation time.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
