Description

Technical Field

[0001] This utility model relates to the field of idler roller processing, specifically to a welding fixture for idler roller frames. Background Technology

[0002] Idler rollers are important components of belt conveyor equipment, generally consisting of a base and rollers mounted on the base. For example, Chinese patent CN221190319U provides an idler roller frame for turning sections, including a support plate. The top of the support plate has three rollers for supporting the belt, and the top of the support plate is fixedly equipped with three sets of mounting components for mounting the rollers. Each set of mounting components includes two mounting brackets, with the rollers positioned between the two mounting brackets. Threaded rods are rotatably mounted at the center of both sides of each of the three rollers. In similar prior art idler roller frames, the base generally has four mounting brackets for mounting the rollers. The mounting brackets are typically welded to the base. During welding, it is necessary to ensure precise distances between the mounting brackets. Therefore, providing an auxiliary tooling that ensures accurate welding of the mounting brackets is a problem that this utility model urgently needs to solve. Utility Model Content

[0003] The purpose of this utility model is to provide a welding fixture for idler frame, which can accurately position the idler frame base and mounting frame during the welding process, ensuring the accurate installation of the roller in the later stage.

[0004] To achieve the above objectives, this utility model provides a roller frame welding fixture, which includes a base, positioning key blocks at both ends of the base, and first L-shaped frames at both ends of the base. The horizontal section of the first L-shaped frames is connected to a first U-shaped clamp, and two second L-shaped frames are arranged between the two first L-shaped frames. The horizontal section of the second L-shaped frames is connected to a second U-shaped clamp.

[0005] Preferably, the base is provided with a first pressure rod in the horizontal direction, and the middle part of the first pressure rod is connected to a second pressure rod in the horizontal direction via a vertical rod;

[0006] The first pressure bar and the second pressure bar are capable of displacement in the vertical direction.

[0007] Preferably, a cylinder is provided at each end of the base, and the two ends of the first pressure rod are respectively connected to the piston rod of the cylinder.

[0008] Preferably, both the first pressure rod and the second pressure rod are fitted with rubber sleeves.

[0009] Preferably, both the first U-shaped card and the second U-shaped card have rubber pads on their surfaces.

[0010] Beneficial effects: This utility model provides a welding fixture for idler frame, which includes a base, positioning key blocks at both ends of the base, and a first L-shaped frame at both ends of the base. The horizontal section of the first L-shaped frame is connected to a first U-shaped clamp, and two second L-shaped frames are arranged between the two first L-shaped frames. The horizontal section of the second L-shaped frame is connected to a second U-shaped clamp. The roller frame welding fixture provided by this utility model is used to assist in the welding of the roller seat and the mounting bracket thereon. The end of the roller seat forms a support base with mounting holes. These mounting holes and positioning key blocks cooperate. During welding, the roller seat is placed on the base, and the positioning key blocks engage with the mounting holes to position the roller seat. The roller seat is a long strip structure with an inverted V-shaped cross-section. The first mounting brackets on both sides include vertical sections and bent sections. The lower end of the vertical section forms a V-shaped groove that engages with the roller seat. The two second mounting brackets in the middle are inverted U-shaped structures, and the openings of the U-shaped structures also form V-shaped grooves for engaging. After the roller seat is positioned, the vertical section of the first mounting frame is engaged in the first U-shaped clip, and the second U-shaped clip is engaged in the U-shaped structure of the second mounting frame. The first and second U-shaped clips can be used to accurately position the first and second mounting frames. The upper ends of the first and second mounting frames are formed with groove structures for mounting rollers. The first mounting frames at both ends are higher than the second mounting frame in the middle. When the first and second pressure rods move down, they can be engaged in the groove structures of the two mounting frames respectively, so as to press the two mounting frames tightly onto the roller seat, which facilitates subsequent welding.
