Embodiment Construction
[0033] For the sake of reference and clarity, the technical terms, abbreviations or abbreviations used below are recorded as follows:
[0034] Laminated linear motor induction plate: The motor is divided into two types: rotary motor and linear motor according to the motion form. When the former motor is working, the rotating part is called the rotor. When the latter is working, the moving part (equivalent to the rotating motor rotor) moves along a straight line. The induction plate of the motor is equivalent to the stator of the motor. When the rotor is energized, the induction plate installed on the corresponding position of the rotor generates an induced magnetic field, which generates a thrust on the rotor and pushes the rotor to move in a straight line along the area where the induction plate is paved. At present, there are Dozens of urban rail transit lines in Beijing, Guangzhou and other cities in my country use linear motor traction;

The invention discloses a welding clamp and method for an induction board of a linear motor. The clamp comprises a frame, a worktable arranged at the upper portion of the frame, a forcing device arranged at the bottom of the frame, limiting blocks arranged at the two ends of the worktable, and an ejecting block. The movable end of the forcing device supports the ejecting block. The worktable is provided with a through hole for the ejecting block to penetrate. A combined body of a square steel assembly and a steel channel assembly is clamped among the limiting blocks and the ejecting block. The ejecting block supports the bottom of the square steel assembly. The two ends of the steel channel assembly are fixed through the limiting blocks. The work face of the ejecting block is machined into a corresponding curved face according to the curved face shown through thermal deformation after the induction board of the linear motor is welded. Before welding, the forcing device exerts acting force through the ejecting block so that all parts of the combined body of the square steel assembly and the steel channel assembly can be subjected to reverse pre-deformation, and the thermal deformation generated after welding is offset. According to the welding clamp and method for the induction board of the linear motor, the technical problem that serious deformation exists after welding of the induction board product of the linear motor, and shaping and correcting need to be conducted can be effectively solved.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a reverse pre-deformation welding jig and a welding method applied to an induction plate of a laminated linear motor. Background technique [0002] Welding is a technological process in which two or more pieces of the same or dissimilar metals are melted by heating, and linked together by atomic or molecular combination and diffusion. Because of the heat input during the welding process, the shrinkage of the material in the weld and its surrounding area will cause thermal deformation, and the thermal deformation often makes the welded structure exceed the design technical requirements. When the deformation of the post-welding structure exceeds the technical requirements, measures should be taken to correct or prevent it. At present, the commonly used corrective measures in industrial production mainly include mechanical straightening and flame straightening. Both of these meth...
