Description

Technical Field

[0001] This utility model relates to the technical field of pump shaft processing, and in particular to a pump shaft straightening device. Background Technology

[0002] The pump shaft is a crucial component of the pump, and its coaxiality is an indicator of the consistency between the pump shaft's rotation axis and a reference axis. Deviations in coaxiality can cause vibration and noise during operation, increasing wear and tear. The quality and performance of the pump shaft directly affect the pump's efficiency and service life. Therefore, during the pump shaft manufacturing process, shafts with abnormal coaxiality need to be adjusted and corrected to ensure pump performance. Existing technology publication number CN208288713U discloses a pump shaft straightening device, including a bracket and a base plate mounted on the bracket. A movable pad is provided on the base plate; a hydraulic head is mounted on the movable pad, and a pressure head for straightening the pump shaft is connected to the lower part of the hydraulic head; the control input end of the hydraulic head is connected to a hydraulic pump, and the control input end of the hydraulic pump is connected to a control device. However, in use, the pump shaft lacks fixation. When the pressure head moves downwards to straighten the bent parts of the pump shaft, the pump shaft is prone to rotation, affecting the operating effect. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a pump shaft straightening device that can fix the pump shaft, ensure stability during straightening, facilitate intuitive and quick identification of the bent part of the pump shaft, and improve work efficiency.

[0004] This utility model discloses a pump shaft straightening device, comprising a worktable, a base, a position adjustment component, a straightening component, a support component, a clamping component, and a calibration component. The worktable is mounted on the top of the base, and the position adjustment component is mounted on the worktable. The straightening component is mounted on the position adjustment component, the support component is mounted on the left and right ends of the top of the worktable, the calibration component is mounted in the middle of the top of the worktable, and the clamping component is mounted on the left and right ends of the worktable. The pump shaft is placed on the support component, the calibration component locates the bent part of the pump shaft, and the clamping component fixes the pump shaft. At the same time, the position adjustment component moves the straightening component to the bent part, and the straightening component straightens the bent part. This process is repeated to ensure the coaxiality of the pump shaft.

[0005] Preferably, the position adjustment assembly includes two threaded rods, two adjusting sliders, a moving frame, two reducers, and a dual-output motor. Adjustment grooves are provided at both the front and rear ends of the worktable. The two threaded rods are rotatably installed within the adjustment grooves, and the adjusting sliders are slidably installed within the adjustment grooves and screwed onto the outer walls of the threaded rods. The input ends of the threaded rods are connected to the output ends of the reducers. The dual-output motors are installed on the right side wall of the worktable, and their output ends are connected to the input ends of the reducers. The front and rear ends of the bottom of the moving frame are connected to the adjusting sliders. Starting the dual-output motors drives the threaded rods to rotate via the reducers, causing the adjusting sliders to move within the adjustment grooves, thereby moving the moving frame above the worktable to adjust and calibrate the position.

[0006] Preferably, the straightening component includes two connecting rods, a hydraulic cylinder, a pressure head, and a mounting rod. The two connecting rods are installed on the front and rear sides of the upper part of the moving frame, the hydraulic cylinder is installed at the middle of the top of the moving frame, the pressure head is installed at the bottom of the hydraulic cylinder, and the mounting rod is connected between the front and rear ends of the hydraulic cylinder and the top of the moving frame. After the moving frame moves the pressure head to the bent part, the hydraulic cylinder is activated to move the pressure head downward to contact and press the pump shaft. This process is repeated to straighten the pump shaft.

[0007] Preferably, the calibration assembly includes two third electric telescopic rods, a mounting strip, and a straightening rod. The two third electric telescopic rods are installed at the left and right ends of the workbench. The mounting strip is installed on the top of the third electric telescopic rod, and the straightening rod is installed on the top of the mounting strip. Activating the third electric telescopic rod pushes the mounting strip upward, so that the straightening rod contacts the bottom of the pump shaft, which makes it easy to find the bent part of the pump shaft intuitively and quickly, and helps to improve work efficiency.

[0008] Preferably, the support assembly includes two sets of support seats, two sets of support rollers, and two geared motors. The two sets of support seats are respectively installed at the left and right ends of the top of the workbench. Support rollers are rotatably installed on the support seats, and the input end of one of the support rollers is connected to the output end of the geared motor. The two ends of the pump shaft are placed between the two support rollers at the left and right ends to support the pump shaft. The geared motor is started to drive the support rollers to rotate, thereby driving the pump shaft to rotate, which facilitates the quick identification of the bent parts.

[0009] Preferably, the clamping assembly includes two mounting frames, two electric telescopic rods, two pressure rollers, two sets of diagonal bars, two second electric telescopic rods, and two limiting plates. The two mounting frames are installed at the left and right ends of the top of the worktable. The front and rear ends of the outer wall of the mounting frame are connected to the top of the worktable by the second electric telescopic rods. The top of the mounting frame is equipped with an electric telescopic rod, and the top of the electric telescopic rod is equipped with a pressure roller. The side wall of the mounting frame is equipped with a second electric telescopic rod, and the telescopic end of the second electric telescopic rod is equipped with a limiting plate. After the pump shaft is placed on the top of the support roller, the electric telescopic rod is activated to drive the pressure roller to move downward and contact and press against the top of the pump shaft to ensure stability during rotation. During straightening, the second electric telescopic rod is activated to limit the two limiting plates on both sides of the pump shaft to ensure stability during straightening.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the pump shaft is placed on the support assembly, the bending part of the pump shaft is found by the calibration assembly, the pump shaft is fixed by the clamping assembly, and at the same time the position adjustment assembly drives the straightening component to move to the bending part, and the bending part is straightened by the straightening component. This process is repeated to ensure the coaxiality of the pump shaft. Attached Figure Description
