Problems solved by technology

[0004] 1. The usual welding fixture requirements for weldments are butt joints of weldments of the same thickness. For weldments of unequal thickness or lap joints, it is not easy to effectively fix the weldments
[0005] 2. In the process of fixing the welded parts, the weld gap between the welded parts is not easy to be accurately controlled
[0007] 4. Welding parts are usually prone to deformation during the welding process due to uneven heating of various parts
[0008] 5. During the welding process of the welded parts, the back molding is not easy to control
[0009] 6. During the welding process of the weldment, the weld on the back is prone to oxidation

Embodiment 1

[0042] For the butt welding experiment of welded parts with the same thickness, place the spacer in the rectangular groove of the base plate, adjust the backing plate adjustment device on both sides of the welding fixture, so that the backing plate is at the same height, and place the welding parts to be welded separately. On the backing plates on both sides, align the joint of the weldment with the center of the groove of the spacer, accurately control the size of the gap reserved between the welds through the gap ruler, place the piano key type pressure plate on the top surface of the weldment, adjust The lateral position of the pressing plate makes it above the piano key type pressing plate, and the fixing bolts on the pressing plate frame are tightened to fix the weldment under the piano key type pressing plate.

Embodiment 2

[0044] For the lap welding experiment of welded parts with the same thickness, by adjusting the height difference of the backing plate adjustment device on both sides to be equal to the thickness value of the sample, the welded parts to be welded are respectively lapped on the backing plates on both sides, and the keyboard type The pressing plate is placed on the weldment, the position of the pressing plate frame is adjusted so that it is above the piano key type pressing plate, and the fixing bolts on the pressing plate frame are tightened to fix the weldment under the piano key type pressing plate.

Embodiment 3

[0046] For the butt welding experiment of welded parts with different thicknesses, place the spacer in the rectangular groove of the substrate, adjust the backing plate adjustment device on both sides so that the height difference of the backing plate is equal to the difference in the thickness of the weldment, and weld the required welding The parts are placed on the backing plates on both sides, so that the joints of the welded parts are aligned with the center of the groove of the pad, and the gap size reserved for the weld is precisely controlled by the gap ruler. The position of the frame makes it be on the top of the piano key type pressing plate, and the fixing bolts on the pressing plate frame are tightened to fix the weldment under the piano key type pressing plate.

Abstract

The invention discloses a weldment clamp. The weldment clamp comprises a base plate, a pressing plate mechanism and a cushion plate mechanism. The base plate of the weldment clamp is provided with the pressing plate mechanism and the cushion plate mechanism. The pressing plate mechanism comprises a pressing plate, a pressing plate frame and a pressing plate bolt, and the pressing plate of the pressing plate mechanism is arranged above the top face of a weldment. The cushion plate mechanism of the weldment clamp comprises a cushion plate and a cushion plate adjusting device, and the cushion plate is arranged on the bottom face of the weldment. The pressing plate mechanism and the cushion plate mechanism are combined and designed and commonly act on the weldment, welding is fixed and firm, and the welding quality is further improved.

Description

Technical field: [0001] The present invention relates to the field of welding devices, in particular to a weldment fixture for butt or lap joints. Background technique [0002] Welding experiment is a manufacturing process and technology for joining metal or other thermoplastic materials by means of heating, high temperature or high pressure. The forms of welding joints mainly include butt joints, lap joints, T-joints, etc. The existing welding fixtures are usually used It is suitable for butt joints of samples of the same thickness, but for the butt and lap welding experiments of samples of unequal thickness, it is not easy to fix it with the usual welding fixture. [0003] The following problems exist in the welding process of weldments: [0004] 1. The usual weldment fixtures require the weldments to be butt joints of weldments of the same thickness. For weldments of unequal thickness or lap joints, it is not easy to effectively fix the weldments. [0005] 2. In the pro...
