Problems solved by technology

[0003] The traditional preheating is to use the torch to bake the welding position of the workpiece on the platform. After one position is heated, manually rotate the workpiece, adjust the torch, and continue to bake the next position; but when the torch is placed on a fixed support to preheat , since the torch and the cylinder are not moving, the cylinder can only be preheated locally, resulting in uneven preheating and affecting the welding quality, which in turn will affect the preheating effect and efficiency of the cylinder;

specific Embodiment approach

[0059] As a specific embodiment of the present invention, the rotating mechanism 5 includes:

[0060] Motor 51; the motor 51 is fixed in the body 1; used to provide power;

[0061] Telescopic rod 52; one end of the telescopic rod 52 is affixed to the rotating shaft of the motor 51; the end of the telescopic rod 52 away from the motor 51 runs through the body 1 and is rotationally connected with the body 1, and the telescopic rod 52 is far away from the output shaft of the motor 51 One end of one end is fixedly connected with the placement table 31;

[0062] When performing preheating treatment on different welding surfaces, the staff starts the motor 51. After the motor 51 is started, it drives the telescopic rod 52 fixed on the rotating shaft of the motor 51 to rotate. The cylinder on the platform 31 rotates to preheat the different welding surfaces of the cylinder, which improves the heating area of ​​the cylinder by the baking gun 21, avoids the uneven preheating of the cy...

Embodiment approach

[0073] As a specific embodiment of the present invention, the body 1 is provided with a bracket 9 on the side close to the air duct 8, one end of the bracket 9 is fixedly connected to the body 1, and the other end is sleeved on the air duct 8;

[0074] The bracket 9 is fixed on one side of the body 1. When the placing table 31 squeezes and expands the airbag fixed on the body 1, it may cause unnecessary deviation of the airway 8 suspended on the side of the airbag, affecting the airway. 8 to clean the surface of the cylinder body, so a bracket 9 is fixedly connected to one side of the body 1, providing an additional support point for the air guide tube 8, improving the practicability of the air guide tube 8 for cleaning the surface of the cylinder body, and avoiding extrusion The deflection of the air guide tube 8 during the process of the air bag ensures that the air guide tube 8 cleans the entire cylinder surface.

Abstract

The invention belongs to the technical field of cylinder body machining, and particularly relates to equipment for improving the preheating efficiency of a cylinder body before welding. Comprising a body, and an oven is arranged on one side of the body and used for providing a heat source; a baking gun is fixedly connected to the top of the oven and penetrates through the body, and a gun nozzle of the baking gun faces the cylinder body; the locking mechanism is arranged above the body and is used for fixing the cylinder body; the telescopic mechanism is arranged in the body and used for driving the locking mechanism to move. The rotating mechanism is arranged in the body and used for driving the locking mechanism to rotate; through cooperation of the locking mechanism, the telescopic mechanism and the rotating mechanism, the cylinder body fixed to the locking mechanism can preheat welding seams of different heights on the cylinder body through operation of the telescopic mechanism and the rotating mechanism, and can preheat different welding faces of the cylinder body, the heating area of a welding gun on the cylinder body is increased, and the welding quality of the cylinder body is improved. And the phenomenon of non-uniform preheating of the cylinder body is avoided, so that the preheating effect and the preheating efficiency of the cylinder body are improved.

Description

technical field [0001] The invention belongs to the technical field of cylinder block processing, in particular to a device for improving the preheating efficiency of a cylinder block before welding. Background technique [0002] Preheating before welding is a process measure to properly heat the weldment locally and as a whole before welding. Its purpose is to reduce the cooling rate of welded joints, avoid hardened structures and reduce welding stress and deformation. It is an effective method to prevent welding cracks; [0003] The traditional preheating is to use the torch to bake the welding position of the workpiece on the platform. After one position is heated, manually rotate the workpiece, adjust the torch, and continue to bake the next position; but when the torch is placed on a fixed support to preheat , since the torch and the cylinder are not moving, the cylinder can only be preheated locally, resulting in uneven preheating and affecting the welding quality, wh...
