Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a steering positioning device for automotive welding. Background Technology

[0002] Automotive parts are the various units that make up a car and the various components that serve the car. As people's living standards improve, people are consuming more and more cars, and the types of automotive parts are constantly expanding. Among the various automotive parts, such as car seat support components and in-vehicle system support components, all need to be welded during production.

[0003] Existing welding fixtures for automotive parts have the following drawbacks: During the welding process of automotive parts, the fixture is needed to position the parts. At the same time, sometimes it is necessary to weld parts of the components at different angles. Therefore, the fixture needs to be rotated and adjusted during the welding process. Existing welding fixtures only have basic positioning and simple adjustment functions, but lack a positioning structure for the rotation angle. Determining the rotation angle is time-consuming and inconvenient to adjust. Therefore, we propose a steering positioning device for automotive welding. Utility Model Content

[0004] The main purpose of this utility model is to provide a steering positioning device for automotive welding. Through the positioning mechanism set inside the frame, the tooling adjustment angle can be quickly determined and positioned, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A steering positioning device for automotive welding includes a frame and a positioning mechanism. The positioning mechanism is located inside the frame and includes a turntable, a positioning platform, a connecting shaft, a movable disc, a protrusion, a servo motor, a positioning plate, and a positioning block. The turntable is mounted on the top of the frame via a support rod, and the positioning platform is movably connected to the top of the turntable. A connecting shaft extending into the frame is located at the bottom of the turntable rotation assembly. A movable disc is welded to the bottom of the connecting shaft, and a protrusion is welded to the side of the movable disc. A servo motor is bolted to the bottom of the frame, and a positioning plate located at the bottom of the movable disc is mounted on the power output end of the servo motor. A positioning block is welded to the side of the positioning plate.

[0007] Furthermore, it also includes an adjustment mechanism. An adjustment mechanism is provided inside the frame. The adjustment mechanism includes a fixed rod, a fixed clamping ring, a movable rod, a fixed ring, a spring, and a movable clamping ring. A fixed clamping ring is welded to the inner wall side of the frame via the fixed rod, and the fixed clamping ring is attached to the coupling surface. A movable rod is horizontally inserted into the inner wall of the frame away from the fixed rod. A fixed ring is welded to the outer periphery of the movable rod, and a spring located on the outer periphery of the movable rod is installed between the surface of the fixed ring and the inner wall of the frame. A movable clamping ring corresponding to the position of the fixed clamping ring is welded to the end of the movable rod. Under normal use... In use, the fixed clamping ring and the movable clamping ring are fitted together on both sides of the outer periphery of the connecting shaft, which limits the connecting shaft and prevents it from rotating, thus ensuring that the position and angle of the positioning table are fixed. When the angle of the positioning table needs to be adjusted, the movable rod is pulled outward, causing the fixed ring to move towards the inner wall of the frame. The spring is compressed, and at this time, the movable clamping ring loses its limit on the connecting shaft, making it convenient to rotate and adjust the angle of the positioning table. After the appropriate angle is reached, the movable rod is released, and the spring drives the movable rod and the movable clamping ring to return to their original positions. Together with the fixed clamping ring, they fix the angle of the connecting shaft and thus fix the positioning table.

[0008] Furthermore, a bearing is embedded in the middle of the frame, and the connecting shaft passes through the bearing; the bearing is installed at the connection between the frame and the connecting shaft, serving as an auxiliary connection.

[0009] Furthermore, a partition is welded horizontally inside the frame, and the servo motor is installed at the bottom of the partition; the partition welded inside the frame is used to install and position the servo motor.

[0010] Furthermore, a driver is provided on the side of the servo motor surface, and a controller is installed on one side of the frame surface. The signal output terminal of the controller is connected to the signal input terminal of the driver. The controller presets the program according to the number of rotations and angles required for the automotive parts in the welding process. During operation, it sends pulse signals to the driver. The pulse frequency determines the rotation speed, and the number of pulses directly corresponds to the rotation angle, thereby realizing the control of the rotation speed and rotation angle of the servo motor power end.

[0011] Furthermore, the end of the movable rod extends to the outside of the frame, and a pull rod is welded to the end of the movable rod located outside the frame; the pull rod assembly located outside the movable rod facilitates the pulling and adjustment of the movable rod.

[0012] Compared with the prior art, this utility model has the following advantages: The top of the frame is connected to the positioning table via a turntable. The positioning table can rotate along the inside of the turntable, and a fixture can be installed on the top of the positioning table for positioning automotive parts. The bottom of the rotating component inside the turntable is provided with a connecting shaft and a movable disk assembly extending into the frame. In the working state, the protrusion on the side of the movable disk fits against the positioning block on the side of the positioning disk. When it is necessary to rotate the positioning table to adjust the processing position angle, the controller outputs adjustment data to the driver, which controls the servo motor to drive the positioning disk to rotate at a suitable angle. At this time, simply rotate the positioning table. When the protrusion fits against the surface of the positioning block, it indicates that the rotation angle has been adjusted to the correct position. The number of rotations and the specific requirements of different parts can be adjusted accordingly. By pre-setting the rotation angles in the program, the angle of the positioning table can be quickly adjusted to meet the welding processing requirements and improve operational efficiency and accuracy. Under normal use, the fixed clamping ring and the movable clamping ring are matched and clamped on both sides of the outer circumference of the connecting shaft, which limits the connecting shaft and prevents it from rotating, thus ensuring that the position and angle of the positioning table are fixed. When the angle of the positioning table needs to be adjusted, the fixed ring is moved towards the inner wall of the frame by pulling the movable rod. The spring is compressed, and the movable clamping ring loses its limit on the connecting shaft, which facilitates the rotation and angle adjustment of the positioning table. After the appropriate angle is reached, the movable rod is released, and the spring drives the movable rod and the movable clamping ring to return to their original positions. Together with the fixed clamping ring, they fix the angle of the connecting shaft and thus fix the positioning table. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-4 As shown, a steering positioning device for automotive welding includes a frame 1 and a positioning mechanism 2. The positioning mechanism 2 is disposed inside the frame 1. The positioning mechanism 2 includes a turntable 201, a positioning platform 202, a connecting shaft 203, a movable disk 204, a protrusion 205, a servo motor 208, a positioning disk 210, and a positioning block 211. The turntable 201 is mounted on the top of the frame 1 via a support rod, and the positioning platform 202 is movably connected to the top of the turntable 201. The bottom of the rotating assembly of the turntable 201 is provided with a connecting shaft 203 extending into the interior of the frame 1. The movable disk 204 is welded to the bottom end of the connecting shaft 203, and the protrusion 205 is welded to the side of the movable disk 204. The servo motor 208 is fixed to the bottom of the interior of the frame 1 by bolts, and the positioning disk 210 located at the bottom of the movable disk 204 is mounted on the power output end of the servo motor 208. The positioning block 211 is welded to the side of the positioning disk 210.

[0020] The system also includes an adjustment mechanism 3, which is installed inside the frame 1. The adjustment mechanism 3 includes a fixed rod 301, a fixed clamping ring 302, a movable rod 303, a fixed ring 305, a spring 306, and a movable clamping ring 307. The fixed clamping ring 302 is welded to the inner wall side of the frame 1 via the fixed rod 301 and is attached to the surface of the connecting shaft 203. The movable rod 303 is horizontally inserted into the inner wall of the frame 1 on the side away from the fixed rod 301. The fixed ring 305 is welded to the outer periphery of the movable rod 303, and a spring 306 is installed between the surface of the fixed ring 305 and the inner wall of the frame 1. The movable clamping ring 307, corresponding to the position of the fixed clamping ring 302, is welded to the end of the movable rod 303. Under normal use, the fixed clamping ring 302 and the movable clamping ring 307 are clamped on both sides of the outer periphery of the connecting shaft 203, which limits the connecting shaft 203 and prevents it from rotating, thus ensuring that the position and angle of the positioning table 202 are fixed. When it is necessary to adjust the angle of the positioning table 202, the movable rod 303 is pulled outward, causing the fixed ring 305 to move towards the inner wall of the frame 1. The spring 306 is compressed, and at this time the movable clamping ring 307 loses its limit on the connecting shaft 203, which facilitates the rotation and angle adjustment of the positioning table 202. After the appropriate angle is reached, the movable rod 303 is released, and the spring 306 drives the movable rod 303 and the movable clamping ring 307 to return to their original positions. Together with the fixed clamping ring 302, they fix the angle of the connecting shaft 203 and thus fix the positioning table 202.

[0021] The frame 1 has a bearing 206 embedded in the middle, and the connecting shaft 203 passes through the bearing 206. A partition 207 is welded horizontally inside the frame 1, and the servo motor 208 is installed at the bottom of the partition 207. The bearing 206 is installed at the connection between the frame 1 and the connecting shaft 203 to play an auxiliary connection role. The partition 207 welded inside the frame 1 is used to install and position the servo motor 208.

[0022] The servo motor 208 is equipped with a driver 209 on its side surface, and a controller 212 is installed on one side of the frame 1. The signal output terminal of the controller 212 is connected to the signal input terminal of the driver 209. The controller 212 is programmed according to the number of rotations and angles required for the automotive parts in the welding process. During operation, it sends pulse signals to the driver 209. The pulse frequency determines the rotation speed, and the number of pulses directly corresponds to the rotation angle, thereby realizing the control of the speed and rotation angle of the servo motor 208.

[0023] The movable rod 303 extends to the outside of the frame 1, and a pull rod 304 is welded to one end of the movable rod 303 located outside the frame 1; the pull rod 304 assembly located outside the movable rod 303 facilitates the pulling and adjustment of the movable rod 303.

[0024] It should be noted that this utility model is a steering positioning device for automotive welding. During operation, the top of the frame 1 is connected to the positioning table 202 via a turntable 201. The positioning table 202 can rotate along the inside of the turntable 201. A fixture can be installed on the top of the positioning table 202 for positioning automotive parts. The bottom of the rotating assembly inside the turntable 201 has a connecting shaft 203 and a movable disk 204 assembly extending into the frame 1. In operation, the protrusion 205 on the side of the movable disk 204 abuts against the positioning block 211 on the side of the positioning disk 210. When the positioning table 202 needs to be rotated to adjust the processing position angle, the controller 212 outputs adjustment data to the driver 209. The driver 209 controls the servo motor 208 to rotate the positioning disk 210 to a suitable angle. At this time, simply rotate the positioning table 202. When the protrusion 205 abuts against the surface of the positioning block 211, it indicates that the rotation angle has been adjusted to the correct position. This adjustment is applied according to different parts. By pre-setting the number of rotations and the angles of each rotation, the angle of the positioning table 202 can be quickly adjusted to meet the welding processing requirements and improve operational efficiency and accuracy. Under normal use, the fixed clamping ring 302 and the movable clamping ring 307 are clamped on both sides of the outer periphery of the connecting shaft 203, which limits the connecting shaft 203 and prevents it from rotating, thus ensuring that the position and angle of the positioning table 202 are fixed. When the angle of the positioning table 202 needs to be adjusted, the movable rod 303 is pulled outward, causing the fixed ring 305 to move towards the inner wall of the frame 1. The spring 306 is compressed, and at this time, the movable clamping ring 307 loses its limit on the connecting shaft 203, which facilitates the rotation and angle adjustment of the positioning table 202. After the appropriate angle is reached, the movable rod 303 is released, and the spring 306 drives the movable rod 303 and the movable clamping ring 307 to return to their original positions. Together with the fixed clamping ring 302, they fix the angle of the connecting shaft 203 and thus fix the positioning table 202.
