Description

Technical Field

[0001] The utility model relates to the technical field of flange processing, in particular to a fixture for flange processing. Background Art

[0002] A flange, also known as a flange plate or a flange, is a part used for connecting shafts to each other. It is used for connecting between pipe ends, and there are also flanges used at the inlets and outlets of equipment. It can also be used for connecting two pieces of equipment, such as a reducer flange. A flange connection or a flange joint, etc., refers to a detachable connection composed of a flange, a gasket, and bolts connected to each other as a group to form a sealing structure.

[0003] Currently, when processing flanges, a fixture is required to clamp and fix them. However, since flanges are generally annular, when using most existing fixtures to clamp flanges of different sizes, due to the small contact area between the fixture and the flange, the stability of the flange after being clamped is low. During the processing, this may cause the flange to shift or shake, thereby affecting the processing accuracy, and even causing the deviation of the drilling or grinding positions, ultimately affecting the processing quality.

[0004] Therefore, those skilled in the art have provided a fixture for flange processing to solve the problems raised in the above background art. Content of the Utility Model

[0005] The purpose of the content of the utility model is to overcome the deficiencies in the prior art and propose a fixture for flange processing. When this fixture is in use, the third servo motor drives the second threaded rod to rotate, so that the first fixing block at the upper end of the moving plate can move and evenly and spacedly press against the inner wall of the flange. At the same time, the electric telescopic rod at the upper end of the moving plate drives the second fixing block to move, evenly and spacedly pressing against the outer wall of the flange. Thus, it can effectively support and fix the inner and outer walls of the flange, reduce the offset and error during the processing, improve the stability of the processing process, reduce the risk of position offset and shaking, and further improve the processing accuracy and product quality.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] The fixture for flange processing includes a base. In the middle of one side inside the base, a first servo motor is provided. Outside the output end of the first servo motor, two driving wheels are sleeved. Outside each of the two driving wheels, a transmission belt is sleeved. Inside the other side of each of the two transmission belts, a driven wheel is sleeved. Inside each of the two driven wheels, a first threaded rod is sleeved. On both sides of the outside of each of the two first threaded rods, a first sleeve is sleeved. The upper ends of multiple first sleeves are rotatably connected to push rods. The upper ends of multiple push rods are rotatably connected to sliding blocks. The upper ends of multiple sliding blocks are slidably connected to a support plate. In the middle of the inside of the support plate, a second servo motor is provided. The output end of the second servo motor is fixedly connected to a workbench;

[0008] At the lower end of the middle of the inside of the workbench, a third servo motor is provided. Outside the output end of the third servo motor, a driving bevel gear is sleeved. The outside of the driving bevel gear is evenly and spacedly meshed with driven bevel gears. Inside each of the multiple driven bevel gears, a second threaded rod is sleeved. On one side of the outside of each of the multiple second threaded rods, a second sleeve is sleeved. The upper ends of multiple second sleeves are fixedly connected to moving plates. On one side of the upper ends of multiple moving plates, a first fixing block is fixedly connected. On one side of the upper ends of multiple moving plates, an electric telescopic rod is provided. On one end face of each of the multiple electric telescopic rods, a second fixing block is provided;

[0009] Through the above technical solution, when the fixture is in use, the third servo motor drives the second threaded rod to rotate, so that the first fixing block on the upper end of the moving plate can move and evenly and spacedly press against the inner wall of the flange. At the same time, the electric telescopic rod on the upper end of the moving plate drives the second fixing block to move and evenly and spacedly press against the outer wall of the flange. Thus, it can effectively support and fix the inner and outer walls of the flange, reduce the offset and error in the processing process, improve the stability of the processing process, reduce the risk of position offset and shaking, and further improve the processing accuracy and product quality.

[0010] Furthermore, a rotating groove is opened on the outer side of the upper end of the support plate. A rotating ring is fixedly connected to the outer side of the lower end of the workbench. The rotating ring is rotatably connected to the rotating groove;

[0011] Through the above technical solution, the rotatable connection between the rotating ring and the rotating groove can ensure that the rotating motion of the workbench is more stable and accurate, and improve the processing accuracy of the system.

[0012] Furthermore, sliding grooves are evenly and spacedly opened at the lower end of the inside of the workbench. The lower ends of multiple second sleeves are fixedly connected to sliders. Multiple sliders are slidably connected to the sliding grooves;

[0013] Through the above technical solution, when the slider slides in the chute, it can provide additional support and guidance, making the movement of the moving plate more stable, reducing vibration and swing, and improving the working precision and stability of the system.

[0014] Further, both end faces on both sides of the two first threaded rods are rotatably connected to the base;

[0015] Through the above technical solution, through the rotational connection between the two first threaded rods and the base, the first threaded rod can obtain more uniform support during movement, improving the working precision and stability of the entire system.

[0016] Further, both end faces on both sides of the multiple second threaded rods are rotatably connected to the workbench;

[0017] Through the above technical solution, through the rotational connection between the multiple second threaded rods and the workbench, the second threaded rod can obtain more uniform support during movement, improving the working precision and stability of the entire system.

[0018] Further, a control panel is arranged on one end face side of the support plate, and a storage battery is arranged in the middle of the base. The storage battery is electrically connected to the control panel, the first servo motor, the second servo motor, the third servo motor, and the electric telescopic rod;

[0019] Through the above technical solution, through the electrical connection, the control panel can directly manage and control the operation status of the storage battery and each electric device, improving the convenience and efficiency of the device.

[0020] Further, both middle parts on both sides of the upper end of the base are fixedly connected with limit telescopic rods, and the upper ends of the two limit telescopic rods are fixedly connected with the support plate;

[0021] Through the above technical solution, the limit telescopic rod can ensure that the support plate will not exceed the safe range during height adjustment, thus avoiding accidents caused by operation errors and improving the use safety of the device.

[0022] Further, support legs are fixedly connected to the four corners of the lower end of the base;

[0023] Through the above technical solution, the support legs can provide additional support points, effectively disperse the weight, enhance the stability of the entire structure, and prevent tilting or shaking caused by unstable center of gravity.
