Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a novel replaceable multi-station laser welding position changing device. Background Art

[0002] Electric welding is an economical, applicable and technologically advanced method in material connection processing. Electric welding can be used to weld almost any two metal materials, as well as some metal materials and non-metallic materials; it can be used to join small parts together to form large, economical and reasonable structures; different performance materials can be used in different parts of the structure to give full play to the characteristics of various materials; electric welding parts have the characteristics of good air tightness and light weight; electric welding can also be used to weld ultra-thin and ultra-fine materials. Electric welding refers to the use of electrical energy, through heating or pressurization, or both, and with or without filler materials, to achieve atomic bonding of welded parts. The processing equipment used for electric welding is called an electric welder. In today's automotive industry, laser welding is very popular among many companies because it can achieve high-precision welding, which can greatly improve the stability of the car body and the reliability of the structure.

[0003] Traditional laser welding method: a single fixed station is used to produce auto parts. It is impossible to change the production and can only produce at a single station. The equipment cannot be fully utilized. There will be limitations on the welding position of parts with relatively complex structures. Because laser welding is a high-precision welding technology, the accuracy requirements for the welding position of assembled parts are also relatively high. However, in the process of laser welding parts, the assembly parts are affected by multiple groups of clamping cylinders, which limits the accessibility of the welding position of the parts. However, it is currently impossible to adjust the tooling of the part orientation, which brings many inconveniences to the welding operation. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a novel replaceable multi-station laser welding position shifting device, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a new type of replaceable multi-station laser welding displacement device, including a fixed support base, the top surface of the fixed support base is connected to the support beam fixed main frame through a bearing, a first support arm is fixedly installed above the support beam fixed main frame near the left end, a second support arm is fixedly installed above the support beam fixed main frame near the right end, a first working platform is arranged between the second support arm and the first support arm, and a second working platform is arranged between the first support arm and the second support arm.

[0006] Optionally, a flip servo motor is fixedly mounted on the outer sides of the first support arm and the second support arm, and the inner sides of the output shafts of the flip servo motor are fixedly connected to the left and right ends of the first working platform and the second working platform.

[0007] Optionally, a "mouth"-shaped frame penetrating from top to bottom is provided inside the first working platform and the second working platform.

[0008] Optionally, the first working platform and the second working platform are movably installed between the first support arm and the second support arm through bearings.

[0009] Optionally, a servo motor is disposed inside the fixed support base, and the top end of the servo motor output shaft is fixedly connected to the bottom end of the support beam fixed main frame.

[0010] The utility model provides a novel replaceable multi-station laser welding position changing device, which has the following features:

[0011] Beneficial effects:

[0012] 1. This new type of replaceable multi-station laser welding displacement device, through the synergy of this device and the welding robot arm, can realize the replacement of the fixture on the work platform and the flipping of the tooling fixture of a single work platform, thereby ensuring that the welding position can be accurately reached. Due to the high cost of the current laser welding technology, if a single fixed-station part is welded, the equipment cannot be fully utilized, which is a potential waste for the enterprise itself.

[0013] 2. This new type of replaceable multi-station laser welding positioner can not only effectively improve the operating efficiency of laser welding, but also effectively ensure the welding quality when performing laser welding technology operations, and can reduce the working time and labor costs of operators. At the same time, the welding laser positioner can effectively meet the needs of enterprises for laser welding technology. The laser welding positioner of the utility model can realize the replacement of tooling fixtures and the displacement function of the welding process, which plays an important role in the development of laser welding technology.
