Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing technology, specifically relating to a stud welding gun bracket that can be rotated and switched in posture. Background Technology

[0002] In the automotive body-in-white manufacturing sector, as automakers strive to maximize production line utilization, a single production line typically needs to produce multiple car models simultaneously. Due to differences in product design among different car models, studs on automotive body panels often need to be welded at multiple angles.

[0003] However, existing stud welding guns have obvious limitations in practical applications: due to limited working space, insufficient external shaft auxiliary welding angle, or special welding angle requirements caused by the structure of the body-in-white panels themselves, traditional stud welding guns often fail to reach the designated welding position and are difficult to meet multi-angle welding needs, thus affecting welding efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide a stud welding gun holder that can be rotated and switched in posture, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotatable stud welding torch holder, comprising a stud welding torch, a cylinder, a rotating mechanism, a fixed support, a welding torch holder, a rotating plate, and a support frame; the stud welding torch is mounted on the welding torch holder, and the welding torch holder is fixed to one side of the rotating plate; one end of the rotating plate is hinged to the support frame via a bearing, and the support frame is fixed to the upper part of the fixed support; the other end of the rotating plate is hinged to one end of the rotating mechanism, and the other end of the rotating mechanism is hinged to the piston rod of the cylinder; the cylinder is fixed to the side of the support frame, and the extension and retraction of the cylinder can drive the rotating mechanism to move, thereby driving the rotating plate to rotate, so that the stud welding torch can rotate 90 degrees.

[0006] Preferably, a limiting block is fixedly provided on the side of the fixed support to limit the rotation angle of the welding torch bracket.

[0007] Preferably, a position sensor is provided on the upper part of the limiting block to monitor the position of the welding torch bracket.

[0008] Preferably, the rotating mechanism includes an upper connecting plate, a lower connecting plate, a first rotating shaft, a second rotating shaft, and a connecting pin; the upper connecting plate and the lower connecting plate are connected at their middle parts by the connecting pin, and the first rotating shaft and the second rotating shaft are located between the upper connecting plate and the lower connecting plate and are respectively located on both sides of the connecting pin; the first rotating shaft is hinged to the rotating plate, and the second rotating shaft is hinged to the piston rod of the cylinder.

[0009] Preferably, it also includes a solenoid valve, which is electrically connected to the cylinder and is used to control the extension and retraction state of the cylinder through an electrical signal.

[0010] The beneficial effects of this utility model are as follows: By setting up a rotating mechanism driven by a cylinder, this utility model drives the stud welding gun to rotate 90 degrees, effectively solving the problem of multi-angle welding of studs on automotive body panels of different models. It can cope with situations where traditional welding guns cannot weld due to space, external shaft auxiliary angle, or the angle of the panel itself. At the same time, with the help of the solenoid valve forming an electronic control mechanism, the cylinder extension and retraction can be directly controlled by an electrical signal to switch the welding gun angle. The operation is convenient and efficient, without the need for additional complex auxiliary equipment, reducing production costs and improving the adaptability and efficiency of automotive body welding manufacturing.

[0017] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0018] like Figs. 1-3 As shown, this utility model discloses a stud welding gun holder with rotatable and switchable postures, which is suitable for stud welding scenarios in automotive body-in-white. Its specific structure includes a stud welding gun 1, a cylinder 2, a rotating mechanism 3, a fixed support 4, a welding gun holder 5, a rotating plate 6, and a support frame 7.

[0019] The stud welding torch 1 is mounted on the welding torch holder 5, and the two are fixedly connected. The welding torch holder 5 is fixed to one side of the rotating plate 6 and its position is adjusted synchronously with the movement of the rotating plate 6.

[0020] One end of the rotating plate 6 is hinged to the support frame 7 via a bearing, allowing the rotating plate 6 to rotate freely around the hinge point; the support frame 7 is fixed to the upper part of the fixed support 4, providing stable support for the overall structure.

[0021] The other end of the rotating plate 6 is hinged to one end of the rotating mechanism 3, and the other end of the rotating mechanism 3 is hinged to the piston rod of the cylinder 2. The cylinder 2 is fixed to the side of the support frame 7. The rotating mechanism 3 consists of an upper connecting plate 31, a lower connecting plate 32, a first rotating shaft 33, a second rotating shaft 34, and a connecting pin 35. The middle parts of the upper connecting plate 31 and the lower connecting plate 32 are connected by the connecting pin 35. The first rotating shaft 33 and the second rotating shaft 34 are located on both sides of the connecting pin 35 and between the upper connecting plate 31 and the lower connecting plate 32. The first rotating shaft 33 is hinged to the rotating plate 6, and the second rotating shaft 34 is hinged to the piston rod of the cylinder 2.

[0022] Furthermore, a limiting block 8 is fixed to the side of the fixed support 4 to limit the rotation angle of the welding gun bracket 5 and avoid excessive rotation from affecting the welding accuracy; a position sensor 9 is provided on the upper part of the limiting block 8 to monitor the position of the welding gun bracket 5 in real time and ensure accurate welding posture.

[0023] The bracket also includes a solenoid valve, which is electrically connected to cylinder 2 and is used to control the extension and retraction of cylinder 2 via an electrical signal.

[0024] Working principle:

[0025] Initial state: The stud welding torch 1 is at the initial welding angle. At this time, the cylinder 2 is in the retracted (or extended) state. The rotating plate 6 is kept stable under the traction of the rotating mechanism 3. The limiting block 8 forms an initial limit on the position of the welding torch bracket 5. The position sensor 9 monitors and records the initial position.

[0026] Posture switching trigger: When it is necessary to switch the welding angle of the stud welding torch 1, an electrical signal is sent to the solenoid valve through an external control device. The solenoid valve controls the extension and retraction of the piston rod of the cylinder 2 according to the signal.

[0027] Mechanical transmission process: When the piston rod of cylinder 2 extends or retracts, it drives the rotating mechanism 3 to move. Since the upper connecting plate 31 and the lower connecting plate 32 of the rotating mechanism 3 are hinged by the connecting pin 35, and both ends are respectively hinged to the rotating plate 6 and the piston rod of cylinder 2, the linear motion of the piston rod is converted into the rotational motion of the rotating plate 6 around the bearing hinge point through the rotating mechanism 3.

[0028] Angle control and limit: When the rotating plate 6 rotates, it drives the welding gun bracket 5 and the stud welding gun 1 to rotate synchronously until the limit block 8 blocks the welding gun bracket 5. At this time, the stud welding gun 1 completes a 90-degree rotation and reaches the preset welding angle; the position sensor 9 monitors the position of the welding gun bracket 5 in real time to ensure that the welding posture is accurate.

[0029] Reset process: When it is necessary to restore the initial angle, the solenoid valve receives a reverse electrical signal, controls the piston rod of cylinder 2 to extend and retract in the opposite direction, drives the rotating plate 6 to rotate in the opposite direction through the rotating mechanism 3, and the stud welding gun 1 returns to the initial position, completing one attitude switching cycle.

[0030] Through the above structure and principle, this device can achieve 90-degree rotational attitude switching of the stud welding gun 1, meet the needs of different car body models and multi-angle stud welding, and solve the problem that traditional welding guns cannot weld due to angle limitations.

[0031] For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
