DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] Example 1

[0032] Reference Figure 1-4 A fixing fixture comprises a base 1 and four support rods 2. The four support rods 2 are arranged at equal intervals at the bottom of the base 1 to support the base 1.

[0033] The main part of the fixture includes a first fixing component and a second fixing component, which are respectively used to clamp and fix two workpieces to be welded. The first fixing component is arranged above the base 1, and the second fixing component is also arranged above the base 1, but is arranged separately from the first fixing component so as to independently adjust the positions of the two workpieces.

[0034] In order to achieve position adjustment of the first fixed component, the present invention designs a first moving component, which includes a first slide rail 3, which is fixedly arranged on the top of the base 1. The top of the first slide rail 3 is slidably connected with a first slider 4, allowing the first slider 4 to move freely on the slide rail. A first groove is also opened on the top of the slide rail, and a first threaded rod 301 is rotatably connected to the inner walls on both sides. The first threaded rod 301 penetrates the first slider 4 and is threadedly connected thereto. Therefore, when the threaded rod rotates, the slider will move along the slide rail. One end of the threaded rod extends to the outside of the slide rail and is connected to the output end of the first motor 9 fixed on the top of the base 1. When the motor is started, the first slider 4 can be driven to move along the first slide rail 3 through the threaded cooperation between the threaded rod and the slider. A first L-shaped support frame 5 is fixed on the top of the first slider 4. The first fixed component is rotatably connected to this support frame, so it can move with the movement of the support frame.

[0035] The specific structure of the first fixed component includes a first clamping base 11, which is rotatably connected to the top of the first L-shaped support frame 5 through a rotating support column 19. A first cylinder 14 is fixed to one side of the base, and two first slide grooves 13 are opened on the top, and two first clamping plates 12 are set, one of which is fixed to the base, and the other is connected to the output end of the cylinder and can slide in the slide groove. When the cylinder is started, it will push the clamping plate connected to it to move along the slide groove and cooperate with the fixed clamping plate to clamp the workpiece. In addition, a driving component is also connected to the bottom of the rotating support column, including a third motor 20, which is used to drive the rotation of the rotating support column and the entire first fixed component to meet the needs of different welding angles.

[0036] The present application can be used in the field of mechanical manufacturing welding technology, and can also be used in other fields applicable to the present application.

[0037] Example 2

[0038] refer to Figure 2-4, improved on the basis of embodiment 1: a welding fixing fixture, which is applied to the field of mechanical manufacturing welding technology, the structure of the second moving assembly is similar to that of the first moving assembly, including a second slide rail 6, a second slider 7, a second L-shaped support frame 8 and other components, their functions and structures are the same as the corresponding components in the first moving assembly, but are only used to adjust the position of the second fixed assembly, the structure of the second fixed assembly is also similar to that of the first fixed assembly, including a second clamping base 15, a second cylinder 18, a second slide groove 17 and a second clamping plate 16, which are used to clamp and fix the second workpiece to be welded.

[0039] In actual use, firstly, the two workpieces to be welded are placed on the first fixing assembly and the second fixing assembly respectively, and the corresponding cylinders are started for clamping. Then, the positions of the two fixing assemblies are adjusted by the first motor and the second motor respectively, so that the two workpieces are accurately butted. If the welding angle of the workpiece needs to be adjusted, the third motor can also be started to drive the first fixing assembly to rotate. Finally, the welding operation is performed.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 9, the second motor, the third motor 20, the first cylinder 14 and the second cylinder 18 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
