Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding fixture for bearing flanges. Background Technology

[0002] Bearings are essential components in modern machinery. Their main function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. Flanges are connecting parts between pipes, usually used in pairs for connecting pipe ends, and also for connecting two pieces of equipment. Fixing flanges to both ends of a bearing simplifies axial positioning, eliminating the need for bearing housings.

[0003] Traditional bearing flange welding equipment can only weld and fix bearing flanges of the same size during use, and cannot adapt to bearing flanges of different sizes. This leads to frequent tooling adjustments during the welding process, increasing the difficulty of operation and time costs. In addition, traditional tooling often lacks sufficient stability when fixing and positioning bearing flanges, and is prone to displacement or deformation during the welding process, thus affecting the welding quality. Utility Model Content

[0004] The purpose of this utility model is to provide a welding fixture for bearing flanges. Through the welding unit, the welder can perform full welding along the outer side wall of the bearing flange, improving the flexibility and versatility of welding. Through the limiting unit, bearing flanges of different sizes can be fixed to ensure the stability of the welding process and reduce welding defects caused by the movement of the weldment.

[0005] To achieve the above objectives, a welding fixture for bearing flanges is provided, comprising: a welding table, two supports fixedly connected to the upper end of the welding table, a welding unit for welding bearing flanges disposed between the two supports, two sliding grooves disposed at the upper end of the welding table, sliding seats slidably connected to the inner walls of the two sliding grooves, and a limiting unit for fixing bearing flanges disposed at the upper end of the two sliding seats.

The inner walls of the three grooves are rotatably connected to screws, and the outer walls of the three screws are fitted with threaded sleeves. A positioning frame is fixedly connected to one side of each of the three threaded sleeves.

[0008] According to the welding fixture for bearing flanges, all three screws are fixedly connected to an adjustment knob at one end of the limiting plate.

[0009] According to the aforementioned welding fixture for bearing flanges, the upper end of the welding frame is provided with a through hole that communicates with the transmission housing.

[0010] According to the aforementioned welding fixture for bearing flanges, the drive gear is located on one side of the outer wall of the ring frame, and the drive gear is meshed with a plurality of symmetrically distributed tooth slots.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model provides a welding fixture for bearing flanges, which includes: a welding table 1, two supports 2 fixedly connected to the upper end of the welding table 1, a welding unit 3 for welding bearing flanges arranged between the two supports 2, two sliding grooves 4 arranged at the upper end of the welding table 1, sliding seats 5 slidably connected to the inner walls of the two sliding grooves 4, and a limiting unit 6 for fixing the bearing flanges arranged at the upper end of the two sliding seats 5.

[0025] The welding unit 3 includes a welding frame 301 fixedly connected between the two supports 2. A circular ring frame 302 is rotatably connected to the inner wall of the welding frame 301. Multiple symmetrically distributed toothed grooves 303 are provided on the outer wall of the circular ring frame 302. Two symmetrically arranged electric push rods 304 are installed on the inner wall of the circular ring frame 302. A welder 305 is fixedly connected to the output end of each of the two electric push rods 304. A transmission housing 306 is fixedly connected to the upper end of the welding frame 301. A motor 307 is installed on one side of the transmission housing 306, and a drive gear 308 is fixedly connected to the output end of the motor 307. The welding unit 3 enables comprehensive welding along the outer wall of the bearing flange, improving welding flexibility.

[0026] The limiting unit 6 includes a limiting frame 601 fixedly connected to the upper end of the sliding seat 5. A limiting plate 602 is installed on one side of the limiting frame 601. Three symmetrically arranged grooves 603 are provided on one side of the limiting plate 602. Screws 604 are rotatably connected to the inner walls of the three grooves 603. Threaded sleeves 605 are fitted onto the outer walls of the three screws 604. A positioning frame 606 is fixedly connected to one side of each of the three threaded sleeves 605, and a protective pad is installed on the outer wall of the positioning frame 606. The limiting unit 6 can limit and fix bearing flanges of different sizes, ensuring stability during the welding process.

[0027] Three screws 604 pass through one end of the limiting plate 602 and are all fixedly connected to an adjusting knob 6041. By adjusting the knob 6041, the screws 604 are rotated, thereby causing the threaded sleeve 605 to move along the axial direction of the screws 604.

[0028] The upper end of the welding frame 301 has a through hole 3011 that communicates with the transmission housing 306. The through hole 3011 facilitates the connection between the transmission housing 306 and the welding frame 301.

[0029] The drive gear 308 is located on one side of the outer wall of the ring frame 302, and the drive gear 308 meshes with multiple symmetrically distributed toothed grooves 303. The meshing of the drive gear 308 with the toothed grooves 303 drives the ring frame 302 to rotate within the welding frame 301.

[0030] Cylinders 7 are installed on both sides of the welding table 1, and the output ends of the two cylinders 7 are fixedly connected to two sliding seats 5 respectively. The cylinders 7 push the sliding seats 5 to slide in the slide groove 4, thereby adjusting the position of the limiting unit 6.

[0031] A controller 101 is installed on the front side of the welding table 1. The controller 101 is electrically connected to the electric push rod 304, the welder 305, the motor 307, and the cylinder 7. The controller 101 facilitates the welding operation of the flange by the operator.

[0032] Working principle: In use, the bearing flange to be welded is placed between the two limiting plates 602, and the two cylinders 7 are activated to push the sliding seat 5 to slide in the slide groove 4. The movement of the two sliding seats 5 causes the two limiting plates 602 to move closer to both sides of the bearing flange and clamp it. In addition, during the clamping process, the three adjusting knobs 6041 can be rotated to drive the screw 604 to rotate, causing the three threaded sleeves 605 to move along the axial direction of the screw 604. The movement of the three threaded sleeves 605 causes the positioning frame 606 to support and fix the inner wall of the flange bearing, thereby further improving the bearing flange's stability. To ensure the stability of the flange bearing, after it is fixed, two electric push rods 304 can be activated to output the welding device 305, so that the welding head of the welding device 305 is close to the outer wall of the flange bearing for welding. In addition, during the welding process, the motor 307 can be activated to drive the drive gear 308 to rotate. The drive gear 308 rotates and meshes with multiple tooth grooves 303, so that the ring frame 302 rotates on the inner wall of the welding frame 301. The rotation of the welding frame 301 can change the position of the welding device 305, so that the welding device 305 can weld the bearing flange from all directions.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
