Description

Technical Field

[0002] A welding robot is an industrial robot used for welding. An industrial robot is a multi-purpose, reprogrammable, automatically controlled manipulator with three or more programmable axes, used in industrial automation.

[0003] Most welding robot arm devices currently on the market are similar, but some shortcomings have been found in actual production operations. For example, most welding robot arms cannot move, the range of motion of truss-type welding robot arms is relatively fixed, and the stopping device of free-moving welding robot arms is set at the bottom of the chassis. When the welding robot arm moves a lot, it is easy to cause instability. Increasing the chassis size will make it difficult to drive.

[0004] Therefore, this application provides a base for a mechanical welding arm to solve the above problems. Utility Model Content

[0005] The technical problem this invention aims to solve is that most welding robot arms are immobile, gantry-type welding robot arms have a relatively fixed range of motion, and the stopping device of free-moving welding robot arms is located at the bottom of the chassis. This can easily lead to instability when the welding robot arm moves significantly, and increasing the chassis size can make driving inconvenient. Therefore, this invention provides a base for a mechanical welding arm, the base comprising:

[0006] The base body has a vibration damping layer on its upper surface and a movable chassis fixedly installed at its lower end. Inside the base body, from left to right, are arranged a first drive device cavity, a power supply cavity, and a second drive device cavity. A first drive mechanism is installed in the first drive device cavity to drive the movable chassis to steer, and a second drive mechanism is used to drive the movable chassis to move. Cooling mechanisms are fixedly installed on both the left and right sides of the base body. Stopping support mechanisms are fixedly installed at the left and right ends of the front of the base body. The same number of stopping support mechanisms are symmetrically arranged at the rear and front of the base body. A power module is fixedly installed inside the power supply cavity.

[0007] Furthermore, the vibration damping layer includes a rigid fixing layer and a soft vibration damping layer. The soft vibration damping layer is laid on the upper surface of the base body, and the rigid fixing layer covers the soft vibration damping layer.

[0008] Furthermore, the stopping support mechanism includes a first telescopic mechanism, a second telescopic mechanism, and a support base plate. The first telescopic mechanism is fixedly connected to the base body. The end of the first telescopic mechanism away from the base body is fixedly connected to the second telescopic mechanism. The end of the second telescopic mechanism away from the first telescopic mechanism is fixedly connected to the support base plate.

[0009] Furthermore, it also includes a first clamp and a second clamp. The first clamp is used to fix the first telescopic mechanism on the base body, and the second clamp is fixedly connected to the end of the first telescopic mechanism away from the base body. The second clamp is used to fix the second telescopic mechanism and the first telescopic mechanism together.

[0010] Furthermore, the first telescopic mechanism is welded to the base body, and the second telescopic mechanism is welded to the end of the first telescopic mechanism away from the base body.

[0011] Furthermore, an anti-slip and wear-resistant layer is fixedly provided on the lower end surface of the supporting base plate.

[0012] Furthermore, air ducts are provided to connect the power supply equipment cavity, the first drive equipment cavity, and the second drive equipment cavity.

[0013] Furthermore, the cooling mechanism is an air extraction cooling mechanism, and the part of the air extraction cooling mechanism that contacts the base body has an air outlet. The side walls of the first drive device cavity and the second drive device cavity also have air inlets.

[0014] Implementing this utility model has the following beneficial effects:

[0015] 1. This utility model is equipped with a vibration damping layer, which can reduce the hard contact between the welding robot arm and the base and reduce some noise. This utility model uses a vacuum cooling mechanism to achieve cooling of all cavities in the base body, with good cooling effect. This utility model adopts a stopping support mechanism, which can control the center of gravity position according to the required range of motion of the welding robot arm, thereby improving the stability of the equipment. This utility model also provides a modular power supply, which can achieve self-powered operation. Attached Figure Description
