Description

Technical Field

[0001] The invention relates to the technical field of welding clamping, in particular to an auxiliary clamp for welding stainless steel doors and windows which is convenient for angle adjustment. Background Art

[0002] When welding stainless steel doors and windows, angle accuracy is one of the key factors to ensure the quality of welding seams and the stability of the overall structure. Traditional welding methods may require workers to touch the welding object with their hands to adjust the welding angle, which may cause uneven or inaccurate welding seams, thereby affecting the appearance and structural strength of the doors and windows. In order to solve this problem, it is very important to design auxiliary clamps for welding stainless steel doors and windows that are easy to adjust the angle.

[0003] The patent with patent number CN202223514664.9 discloses a welding clamping auxiliary device, which provides support for the workpiece and adjusts the position of the workpiece by setting a base and combining the marking scale on the base. The workpiece to be welded is clamped by the first clamping part and the second clamping part respectively, and the position of the workpiece is clamped and fixed before the workpiece is welded to avoid the position of the workpiece being offset during the welding process and affecting the welding quality.

[0004] Although this patent solves the above problems, there is still the problem that the angle between the clamp and the welding object cannot be adjusted during welding, so multi-angle welding cannot be performed and the welding accuracy is low. Therefore, an auxiliary clamp for welding stainless steel doors and windows that is easy to adjust the angle is proposed to solve the above problems. Summary of the invention

A joint device is provided, and a protective device is provided above the base to prevent solder and sparks from splashing and causing danger during welding. The rotating plate is slidably connected to the inner wall of the annular limit slide rail through an arc slider, and the connecting slide seat is slidably connected to the inner surface of the inner ring arc top slide rail, a slide groove is provided on the inner side of the welding plate, and the movable clamping rod is slidably connected to the inner surface of the slide groove, and the linear motor is fixedly connected to the lower surface of the welding plate, and the rotating roller drives the inner ring arc top slide rail to rotate in a semicircular arc front and back, and the inner ring arc top slide rail drives the connecting slide seat to move in an arc front and back, and the rotating plate rotates to drive the outer ring arc top slide rail to rotate, and when the outer ring arc top slide rail rotates, it pushes the connecting slide seat to rotate in a semicircular arc left and right, and the linear motor drives the moving clamping rod to move horizontally, and the moving clamping rod clamps the doors and windows after moving to a certain position, so that the doors and windows are fixed on the welding plate for welding, and when the doors and windows are fixed, the welding plate is rotated.

[0007] Preferably, the adjusting device includes an L-shaped lower clamping plate, a T-shaped upper clamping plate, and a sliding rod, wherein the L-shaped lower clamping plate is arranged on the front side of the welding plate, the T-shaped upper clamping plate is slidably connected to the inner surface of the L-shaped lower clamping plate, and the sliding rod is fixedly connected to the lower surface of the top of the T-shaped upper clamping plate. The adjusting device also includes a horizontal slide, a rotary adjusting member, a limit clamping shaft, a limit sliding column, and an inclined groove limit plate. The horizontal slide is slidably connected to the upper surface of the welding plate, the rotary adjusting member is hinged on the upper surface of the horizontal slide, and the limit clamping shaft is fixedly connected to the horizontal slide. The upper surface, the limit slide is fixedly connected to the lower surface of the horizontal slide, the inclined groove limit plate is fixedly connected to the lower surface of the welding plate, the L-shaped lower clamping plate is provided with a through groove, and the inner wall of the through groove is clamped with the slide rod, a spring is arranged between the lower surface of the top of the T-shaped upper clamping plate and the top surface of the L-shaped lower clamping plate, an inclined groove is arranged on the inner side of the welding plate, and the limit slide is slidably connected to the inner surface of the inclined groove, the limit slide is slidably connected to the inner surface of the inclined groove limit plate, an arc-shaped slide groove is arranged on the inner side of the rotation adjustment member, and the limit clamping shaft and the inner surface of the arc-shaped slide groove are connected The surface is clamped, the L-shaped lower clamp and the side of the rotating adjustment part away from the moving clamp rod are fixedly connected, the T-shaped upper clamp is lifted, and the T-shaped upper clamp is away from the L-shaped lower clamp. At this time, the door and window to be welded are placed on the L-shaped lower clamp, and then the T-shaped upper clamp is released.

When it is necessary to weld special-shaped doors and windows with curved corners or other non-right angles such as fan-shaped, ordinary clamps cannot fit with the corners of doors and windows, making it difficult to clamp, the clamping is unstable, and the rotation and rotation are difficult. The adjusting piece is rotated to offset the angle of the L-shaped lower clamping plate, so that the L-shaped lower clamping plate can be adjusted to an angle that fits the corners of special-shaped doors and windows to clamp the doors and windows. When the linear motor drives the movable clamping rod to move, the movable clamping rod pushes the horizontal slide to move along the inclined groove opened on the welding plate toward the center of the welding plate. When the four horizontal slides at the four corners of the welding plate are guided by the inclined groove and gathered toward the center of the welding plate, the clamping range becomes smaller. Conversely, when the movable clamping rod drives the four horizontal slides to move toward the outside of the welding plate, the clamping range of the device becomes larger.

During the welding process, when the solder and sparks splash out of the device, they are blocked by the V-shaped baffle plate and the top plate. When the horizontal slide seat slides closer or farther away according to the size of the door and window, it drives the limit slide column to slide in the inclined groove limit plate. The limit slide column drives the T-shaped transmission rod to move forward or reversely along the horizontal center axis of the inclined groove. The T-shaped transmission rod drives the transmission shaft to slide in the slide groove support rod, and the transmission shaft drives the V-shaped sliding bottom plate on the slide groove support rod to move forward or reversely along the horizontal center axis of the inclined groove.

The rotation of the welding plate drives the door and window body to adjust the angle, which is convenient for fine-tuning after the overall angle adjustment is completed, further improving the angle adjustment effect and making the welding more delicate and accurate.

[0011] 2. The auxiliary clamp for welding stainless steel doors and windows, which is easy to adjust the angle, has a T-shaped upper clamp that stops after it touches the doors and windows, so that the L-shaped lower clamp and the T-shaped upper clamp can clamp doors and windows of different thicknesses, thereby improving the applicability of the device.

[0012] 3. The auxiliary clamp for welding stainless steel doors and windows, which is easy to adjust the angle, is used to prevent the solder and sparks from splashing outside the device by the V-shaped baffle and the top plate, so as to prevent the solder and sparks from splashing outside the device and causing unnecessary danger and damage to the workers and other objects, thereby improving the safety of the device in use.
