Description

Technical Field

[0001] The utility model relates to the field of welding gun bracket manufacturing, in particular to a welding gun bracket which is easy to install and position. Background Art

[0002] The welding gun is a tool used for gas welding. The welding gun uses the high current and high voltage of the welding machine to generate heat that gathers at the end of the welding gun to melt the welding wire. The molten welding wire penetrates into the part to be welded. After cooling, the welded objects are firmly connected into one. However, the existing welding gun bracket is only used to fix the welding gun, and its function is relatively single, which cannot meet the complex work requirements. Therefore, a welding gun bracket that is convenient for positioning has emerged.

[0003] For example, a welding gun bracket (publication number: CN213531364U, publication date: 2021-06-25) includes a base, and a plurality of universal wheels are installed on the bottom side of the base; a height lifting device, the height lifting device is slidably installed above the base, and a welding gun mounting fixture is provided on the height lifting device, and a fully automatic servo welding gun is installed on the welding gun mounting fixture, and the height lifting device is used to adjust the height of the fully automatic servo welding gun; a lateral moving device, the lateral moving device is arranged on the top side of the base, the lateral moving device is connected to the height lifting device, and the lateral moving device is used to move the height lifting device laterally, and the lateral moving device includes a first motor, and the first motor is fixedly installed on the top side of the base.

[0004] The welding gun bracket adjusts the position of the fully automatic servo welding gun through a lateral moving device and a height lifting device, observes the position of the product to be welded through a special welding strong light monitoring camera, and remotely controls the fully automatic servo welding gun to adjust the position for welding. It has a high degree of automation and can automatically displace and weld multiple welding points on a plane, with strong adaptability. However, the welding gun bracket can only weld within a certain height range. When the bracket is assembled beyond this height range, the welding device is difficult to adapt to this height, and it occupies a large area. It is not easy to move the bracket to a suitable height tool for welding, thereby reducing the scope of application of the bracket. In addition, the clamp of the welding gun bracket cannot meet the needs of fixing welding guns of various sizes and types.

[0005] For example, a lifting welding device for a bracket (publication number: CN219852819U, publication date: 2023-10-20) includes a connecting frame and a welding gun assembly. Ear plates are fixed on the left and right sides of the connecting frame. A connecting mechanism is provided on the connecting frame. The connecting mechanism includes a lifting assembly for adjusting the height of the welding gun assembly and a positioning assembly for positioning with the bracket. The device is provided with a lifting assembly, which can easily adjust the height of the welding gun, and the distance moved by the welding gun is accurately identified by the rangefinder to facilitate welding of workpieces of different heights; a positioning assembly is provided to fix the device in a suitable position. However, the welding gun bracket cannot only have a lifting assembly, lacks a component that moves left and right, and cannot better locate the exact position of the welding point.

DETAILED DESCRIPTION

[0023] The following is combined with Figures 1 to 3 The implementation methods of the present invention are described with relevant embodiments, but the implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as the known technology in this technical field and can be known and mastered by the technicians in this technical field.

[0024] The utility model provides a welding gun bracket which is easy to install and position. Figure 1 and Figure 2 As shown, it includes a base 1, a clamping assembly 4 for clamping a welding gun, a lifting mechanism 2 for adjusting the height of the clamping assembly 4, and a left-right translation mechanism 3 for adjusting the horizontal position of the clamping assembly 4. The lifting mechanism 2 is arranged above the base 1, the left-right translation mechanism 3 is slidably arranged on the lifting mechanism 2, and the clamping assembly 4 is arranged at both ends of the left-right translation mechanism 3 along the horizontal direction.

[0025] The utility model realizes precise adjustment of the height and horizontal position of the welding gun by combining the lifting mechanism 2 with the left and right translation mechanism 3, improves the accuracy of welding gun positioning, facilitates the positioning of the welding gun, and ensures the precise alignment of the welding gun and the weld, thereby improving the welding quality and efficiency.

[0026] like Figure 2 As shown, the lifting mechanism 2 includes a frame 21, a vertical screw rod 22 and a first motor 23. Both ends of the vertical screw rod 22 are arranged in the frame 21. The setting of the lifting mechanism 2 enables the welding gun to move smoothly and accurately in the vertical direction. By accurately controlling the action of the lifting mechanism 2, the welding gun can be easily adjusted to a suitable distance from the workpiece surface to adapt to workpieces of different heights or thicknesses. This high degree of flexibility enables the utility model to adapt to a variety of welding scenarios, improving its practicality.

[0027] The left-right translation mechanism 3 includes a sliding frame 31, a horizontal screw rod 32 and a second motor 33. One end of the sliding frame 31 close to the vertical screw rod 22 can be slidably mounted on the vertical screw rod 22. The horizontal screw rod 32 is inserted into the middle section of the sliding frame 31 and the two ends of the horizontal screw rod 32 are arranged at the two ends of the sliding frame 31 along its own length direction. The introduction of the left-right translation mechanism 3 further enhances the flexibility of the welding gun bracket. The mechanism can follow the rotation of the vertical screw rod 22 of the lifting mechanism 2 to perform lifting and lowering movements, which means that the movement of the welding gun in the horizontal direction and the movement in the vertical direction can be performed synchronously without complicated adjustments. This design not only simplifies the operation process, but also improves the accuracy of positioning.

[0028] In addition, the utility model also pays attention to the convenience of operation. The entire welding gun bracket occupies a small area, which makes it easier to arrange and move it in the production site. When the bracket is assembled to exceed the height range of the lifting mechanism 2, the welding gun bracket can be easily moved to a tool of a suitable height for welding, which greatly reduces the difficulty of operation and improves work efficiency.

[0029] like Figure 3 As shown, the clamping assembly 4 includes a slider 41 and a clamping ring 42. The slider 41 is slidably mounted on the horizontal screw rod 32. The clamping ring 42 is disposed on a side of the slider 41 away from the vertical screw rod 22. A pair of spring pressing pieces 43 are disposed in the clamping ring 42. The clamping assembly 4 of the utility model is provided with a spring pressing piece 43, which can be used to install and fix welding guns of various sizes and types, thereby improving the practicality and convenience of the clamping assembly 4. The clamping device 421 is used to realize the locking and loosening of the clamping assembly 4, thereby further improving the convenience of welding gun installation.

[0030] like Figure 1 As shown, the utility model is provided with clamping assemblies 4 at both ends of the left and right translation mechanisms 3. Compared with the traditional translation mechanism, the displacement distance of the entire translation mechanism is replaced by the addition of the horizontal displacement distances of the clamping assemblies 4 on both sides, so that during the welding process, the clamping assemblies 4 on both sides are provided with welding guns, and the welding guns can weld multiple welding points through a shorter moving distance, making the welding operation faster and more convenient.

[0031] More specifically, both clamping assemblies 4 on both sides clamp welding guns. When there is a welding spot at the left end of the left-right translation mechanism 3 and a welding spot at the right end of the left-right translation mechanism 3, the operator only needs to move the horizontal screw rod 32 through the second motor 33. The horizontal screw rod 32 drives the clamping assemblies 4 on both sides to move at the same speed at the same time. After the left clamping assembly 4 and the welding gun move to the left welding spot, the reverse motor moves the right clamping assembly 4 and the welding gun to the right welding spot. There is no need to move the same welding gun from the left welding spot to the right welding spot, which shortens the time and displacement of the welding gun movement.

[0032] As one of the preferred embodiments of the present invention, Figure 2 As shown, the first motor 23 is arranged at the bottom end of the frame 21 and connected to the vertical screw rod 22 through the output shaft. When the first motor 23 is started, its output shaft will drive the vertical screw rod 22 to rotate, and the sliding frame 31 is sleeved on the vertical screw rod 22, so that the rotational motion of the screw rod can be converted into the linear motion of the lifting mechanism 2, thereby realizing the lifting and lowering adjustment of the left and right translation mechanism 3 and the welding gun in the vertical direction. In addition, by directly connecting the vertical screw rod 22 through the output shaft, the transmission links are reduced, the transmission efficiency is improved, and the lifting and lowering adjustment of the welding gun is more accurate and fast.

[0033] The second motor 33 is arranged inside the sliding frame 31 and connected to the horizontal screw rod 32 through a transmission assembly. The transmission assembly can be a mechanical transmission structure such as a gear, a belt, a chain, etc., which is used to convert the rotational motion of the motor into the linear motion of the clamping assembly 4 on the horizontal screw rod 32. The second motor 33 is arranged inside the sliding frame 31 to ensure the compactness and structural stability of the entire mechanism. The transmission efficiency is improved, so that the movement of the welding gun in the horizontal direction is more stable and accurate.

[0034] The sliding frame 31 includes a sliding connecting rod 311 and a horizontal screw rod frame 312. The sliding connecting rod 311 is sleeved on the vertical screw rod 22. The horizontal screw rod frame 312 is arranged on one side of the sliding connecting rod 311. A fixed block 314 is provided in the middle of the horizontal screw rod frame 312. Limit blocks 315 are respectively provided at both ends of the horizontal screw rod frame 312. One end of the horizontal screw rod 32 is provided on the limit block 315, and the other end passes through the fixed block 314 and is provided on another limit block 315.

[0035] The clamping assembly 4 is provided with two groups, and the two groups of clamping assemblies 4 are respectively provided at both ends of the horizontal screw rod 32, and each clamping assembly 4 is provided between the fixed block 314 and the limit block 315. The second motor 33 is provided in the fixed block 314 to control the horizontal screw rod 32, and the limit block 315 is used to limit the movement of the clamping assembly 4, so that the clamping assembly 4 moves between the fixed block 314 and the limit block 315.

[0036] Furthermore, a counterweight 313 is provided on the side of the sliding connecting rod 311 away from the horizontal screw rod frame 312. The design of the counterweight 313 is to compensate for the unilateral weight applied by the horizontal screw rod frame 312 to the connecting rod 311 to ensure the balance and stability of the entire mechanism. Due to the weight of the horizontal screw rod frame 312 itself and the weight of equipment such as a welding gun that may be mounted, they will produce different torques when in different positions, which may cause the mechanism to be unstable or offset during movement. Therefore, the counterweight 313 is set to solve this problem. By reasonably arranging the position and weight of the counterweight 313, the weight difference between the connecting rod 311 and the horizontal screw rod frame 312 can be effectively balanced, so that the entire mechanism can remain balanced and stable during movement.

[0037] As one of the preferred embodiments of the utility model, the slider 41 is connected to the clamping ring 42 through a first hinge, and the clamping ring 42 can rotate along the central axis of the first hinge. The clamping ring 42 is composed of two semicircular rings, one end of the two semicircular rings close to each other is connected through a second hinge, and the other end of the two semicircular rings close to each other is connected through a clamping device 421. The clamping device 421 realizes the locking and loosening of the clamping assembly 4, further improving the convenience of welding gun installation.

[0038] The clamping device 421 may be in various forms, such as screws, buckles or springs, which can generate sufficient clamping force to tightly clamp the two semicircular rings together. In this way, even under external force or vibration, the clamping ring 42 can maintain its stability to ensure that the position of the clamped object does not change. When the size of the welding gun is larger than the maximum size that the clamping ring 42 can accommodate, the first hinge can be disassembled and replaced with a suitable clamping ring 42.

[0039] As one of the preferred embodiments of the utility model, each spring pressing piece 43 is arranged on the inner wall of a semicircular ring, and the spring pressing piece 43 is provided with a spring and a pressing piece, and the pressing piece is connected to the semicircular ring through the spring, and the pressing piece is arranged in an arc shape, and the curvature of the outer side of the pressing piece matches the curvature of the inner wall of the semicircular ring. Loosen the clamping device 421, install the welding gun into the clamping ring 42, clamp the clamping device 421, the spring will give a force to the pressing piece, and the pressing pieces on both sides will clamp the welding gun, and the spring pressing piece 43 can install and fix welding guns of various sizes and types.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
