Description

Technical Field

[0001] The present application relates to the technical field of brazing equipment, and in particular to a laser brazing device for a rear cover of an automobile. Background Art

[0002] The main feature of laser brazing is to use the high energy density of laser to achieve local or small area rapid heating to complete the brazing process. The key to laser brazing is to reasonably control the laser power distribution. The melting point of the brazing material is lower than that of the base material. During the laser irradiation, the brazing material melts and adheres to the two separated base materials. The welding is completed after the brazing material solidifies.

[0003] In order to make the welding parts more beautiful during the production, processing and maintenance of automobiles, more and more parts are connected by laser brazing. Due to its irregular shape, the rear cover of the car is not easy to fix during the laser brazing process. Fixing it by hand is very likely to cause shaking during the brazing process, which affects the brazing effect.

[0004] Therefore, it is necessary to design a laser brazing device that is convenient for fixing the rear cover of a car to prevent the problem of poor brazing effect caused by loose fixation during the brazing process of the rear cover of the car. Utility Model Content

[0058] Specifically, four supporting legs 101 are fixedly installed at the bottom surface of the bottom plate 1 near the four corners; a brazing plate 201 is fixedly installed on the bottom plate 1, and a winding shaft 202 is fixedly installed at one end of the brazing plate 201 away from the bottom plate 1, and a spring spring 203 is provided on the outer sleeve of the winding shaft 202, and a coil barrel 204 is provided on the outer sleeve of the spring spring 203, and both ends of the spring spring 203 are respectively fixedly connected to the winding shaft 202 and the coil barrel 204;

[0059] The connecting wire 205 of the soldering gun 2 is wound on the coil tube 204. When the worker pulls the soldering gun 2 to perform soldering, the connecting wire 205 is pulled out. When the worker releases the soldering gun 2, the connecting wire 205 is automatically retracted onto the coil tube 204 under the action of the clockwork spring 203, which is convenient to use.

[0060] Reference Figure 1-5 The automobile rear cover laser brazing device also includes: a placement plate 3, a resistance component 301, a centering plate 4, and a pressure rod 5;

[0061] The abutment assembly 301, the centering plate 4, and the pressure rod 5 respectively abut against the bottom surface, both sides, and the top surface of the rear cover of the automobile to fix the rear cover of the automobile on the bottom plate 1, so that the workers can conveniently perform welding work on the rear cover of the automobile;

[0062] Specifically, the placement plate 3 is arranged in the middle of the bottom plate 1, and four support columns 302 are fixedly installed near the four corners of the bottom surface of the placement plate 3, and the bottom surfaces of the four support columns 302 are fixedly connected to the top surface of the bottom plate 1; the abutment assembly 301 is arranged on the placement plate 3;

[0063] More specifically, the resistance assembly 301 includes: a first liquid storage chamber 303, a first piston cylinder 304, a first piston rod 305, a second liquid storage chamber 306, a second piston cylinder 307, a second piston rod 308, and a resistance block 309; specifically, the two first liquid storage chambers 303 are fixedly mounted on the placement plate 3, and three evenly distributed first piston cylinders 304 are fixedly arranged on the first liquid storage chamber 303, and the three first piston cylinders 304 are all connected to the first liquid storage chamber 303, and the bottom end of the first piston rod 305 is slidably arranged in the first piston cylinder 304; the second liquid storage chamber 306 is fixedly mounted on the top end of the first piston rod 305, and three evenly distributed second piston cylinders 307 are fixedly mounted on the top surface of the second liquid storage chamber 306, and the three second piston cylinders 307 are all connected to the second liquid storage chamber 306, and the bottom end of the second piston rod 308 is slidably arranged in the second piston cylinder 307; the resistance block 309 is rotatably mounted on the top end of the second piston rod 308 in an elliptical spherical shape;

During the rotation of the driving plate 405, the two ends of the driving plate 405 rotate toward the two ends of the base plate 1 respectively, thereby driving the guide plate 402 to move along the guide rail 401, thereby realizing the relative movement of the two centering plates 4.

[0069] The pressure rod 5 is rotatably arranged on the centering plate 4. When the pressure rod 5 rotates, it can contact with the top surface of the rear cover of the car, pressing the rear cover of the car tightly against the contact block 309;

[0070] Two oppositely arranged mounting plates 501 are fixed on the top surface of the centering plate 4, and a pressure rod 5 is arranged between the two mounting plates 501 and hinged with the mounting plates 501.
