[0009] Preferably, the sweeping mechanism includes a roller group, the roller group is fixedly connected to the top of the workbench on the left side of the first limit plate, a second telescopic rod is fixedly connected to the top of the workbench on the right side of the servo motor, and a limit roller is movably connected to the top of the second telescopic rod.

[0010] Preferably, a servo motor is fixedly connected to the front of the first limit plate, and a sweeping brush is fixedly connected to the back of the servo motor on the top of the roller group, and the sweeping brush is fixedly connected to the output shaft of the servo motor.

[0012] Preferably, a suction box is fixedly connected to the bottom of the roller group, an isolation filter screen is fixedly connected to the inside of the suction box, and the bottom of the suction box is fixedly connected to the air pump through a pipeline.

[0013] The present invention provides an auxiliary loading device for processing the pump shaft of a special water pump. It has the following beneficial effects: 1. For this auxiliary loading device for processing the pump shaft of a special water pump, by placing the pump shaft to be processed on the top of the roller group, the pump shaft will roll on the top of the roller group until it fits with the limit roller. The second limit plate makes the pressure sensor move together with the movable claw to squeeze the pump shaft. The pressure sensor will detect that the pressure continues to increase, causing the movable claw to stop moving. Then, the pump shaft is moved to the position corresponding to the movable claw and the fixed claw under the guidance of the first guide rod and the second guide rod. At this time, the movable claw and the fixed claw can directly clamp the pump shaft to achieve rapid positioning of the pump shaft and improve the processing speed.

[0014] 2. The auxiliary loading device for processing the pump shaft of this special water pump. When the two first telescopic rods extend and the pump shaft is pushed upward by the inclined top plate, when the position of the inclined top plate is higher than that of the first guide rod and the second guide rod, the pump shaft will roll into the collection box under the guidance of the first guide rod and the second guide rod, so as to realize the rapid blanking after processing, facilitate the processing of the next pump shaft, and improve the processing speed.

[0015] 3. The auxiliary loading device for processing the pump shaft of this special water pump. By placing the pump shaft on the top of the roller group, the sweeping brush will continuously rotate to push the pump shaft to the right, and make one side of the pump shaft fit with the edge of the limiting roller, which can prevent the pump shaft from tilting and causing the pressure sensor to sense incorrectly, so as to improve the positioning accuracy and make the positioning more accurate.

[0016] 4. The auxiliary loading device for processing the pump shaft of this special water pump. The sweeping brush is continuously driven by the servo motor to rotate. The rotating sweeping brush will brush the surface of the pump shaft. At the same time, the surface of the pump shaft is in contact with the roller group and the limiting roller. When the sweeping brush brushes the surface of the pump shaft, it will also push the pump shaft to rotate. The suction box will suck the debris remaining on the surface of the pump shaft due to the previous processing away from the surface of the pump shaft through the gap between the roller groups, which can improve the processing quality, avoid secondary processing, and improve the processing speed.

[0017] 5. The auxiliary loading device for processing the pump shaft of this special water pump. When the pump shaft rolls downward on the surfaces of the first guide rod and the second guide rod, due to the protrusions, the pump shaft will intermittently collide with the first guide rod and the second guide rod, causing the pump shaft to vibrate, which will loosen the metal debris that may be contaminated on the surface of the pump shaft, and the air flow blown out from the exhaust plate will blow it away from the surface of the pump shaft, blowing the residual metal debris on the surface of the pump shaft away from the surface of the pump shaft, which can improve the processing quality, avoid secondary processing, and improve the processing speed.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0022] Embodiment 1: Please refer to Figures 1-9 , the present invention provides a technical solution: a special water pump pump shaft processing auxiliary feeding device, including a workbench 1, a grinding assembly 3 is fixedly connected to the top of the workbench 1, a collection box 2 is fixedly connected to the right side of the workbench 1, a fixed jaw 5 is fixedly connected to the top of the workbench 1 on the left side of the grinding assembly 3, a movable jaw 4 is movably connected to the top of the workbench 1 on the back of the fixed jaw 5, a driving screw 6 is movably connected to the top of the workbench 1, and the driving screw 6 is movably connected to the movable jaw 4. A positioning and feeding mechanism 7 is fixedly connected to the top of the workbench 1 on the left side of the fixed jaw 5, and a sweeping mechanism 8 is fixedly connected to the outer wall of the positioning and feeding mechanism 7; The positioning and feeding mechanism 7 includes: The first guide rod 701, and the first guide rod 701 is fixedly connected to the top of the workbench 1 on the left side of the fixed jaw 5; The first limit plate 702, and the first limit plate 702 is fixedly connected to the front of the first guide rod 701; The first upper limit rod 703, and the first upper limit rod 703 is fixedly connected to the back of the first limit plate 702 at the top of the first guide rod 701.

[0023] A second guide rod 704 is fixedly connected to the left side of the moving jaw 4. A second limit plate 706 is fixedly connected to the back of the second guide rod 704. A second upper limit rod 705 is fixedly connected to the front of the second limit plate 706 at the top of the second guide rod 704.

[0024] A pressure sensor 709 is fixedly connected to the back of the second limit plate 706. A pushing plate 708 is movably connected to the back of the second limit plate 706. A torsion spring 707 is fixedly connected to the outer wall of the pushing plate 708, and the torsion spring 707 is fixedly connected to the second limit plate 706. The torsion spring 707 functions to transmit power to the pushing plate 708. At the same time, when the pushing plate 708 can no longer push the pump shaft, but the pressure sensor 709 can still push the pump shaft, the pushing plate 708 will rotate around its connection with the second limit plate 706 and cause the torsion spring 707 to deform.

[0025] A first telescopic rod 710 is fixedly connected to the inside of the workbench 1 at the back of the fixed jaw 5. A first telescopic rod 710 is fixedly connected to the front of the moving jaw 4. Oblique top plates 711 are fixedly connected to the tops of both first telescopic rods 710.

[0026] The sweeping mechanism 8 includes a roller group 801. The roller group 801 is fixedly connected to the top of the workbench 1 on the left side of the first limit plate 702. A second telescopic rod 809 is fixedly connected to the top of the workbench 1 on the right side of the servo motor 802. A limit roller 808 is movably connected to the top of the second telescopic rod 809.

[0027] During use, place the pump shaft to be processed on the top of the roller group 801. The pump shaft will roll on the top of the roller group 801 until it fits against the limit roller 808. The driving screw 6 will drive the moving claw 4 to move by rotation. During the movement of the moving claw 4, it will drive the second guide rod 704 to move together. Through the second limit plate 706, the pressure sensor 709 will move together with the moving claw 4 to squeeze the pump shaft, so that the other end of the pump shaft fits against the first limit plate 702. At this time, the pump shaft cannot move, and the pressure sensor 709 will detect that the pressure continues to increase. At this time, stop the rotation of the driving screw 6 to make the moving claw 4 stop moving. This can be applied to pump shafts of different specifications and sizes. When placing multiple pump shafts at one time, the moving claw 4 drives the second limit plate 706 to move, and through the second limit plate 706, it pushes the top plate 708 to move together. The side of the top plate 708 close to the first guide rod 701 will simultaneously push the sides of multiple pump shafts. Under the elastic force of the torsion spring 707 to resist deformation, when one end of the longer shaft contacts the first limit plate 702, the top plate 708 continues to be pushed, causing the top plate 708 to rotate outward from the second limit plate 706 and deforming the torsion spring 707. At this time, the part of the top plate 708 close to the pressure sensor 709 will continue to push the shorter shaft between the longer shaft and the pressure sensor 709, thereby pushing the pump shaft toward the side of the first limit plate 702, and then pushing and positioning the side of the pump shaft close to the first limit plate 702 for subsequent processing.

[0028] Then the second telescopic rod 809 contracts, causing the limit roller 808 to descend, and the pump shaft will move to the position corresponding to the moving claw 4 and the fixed claw 5 under the guidance of the first guide rod 701 and the second guide rod 704. At this time, the moving claw 4 and the fixed claw 5 can directly clamp the pump shaft to achieve rapid positioning of the pump shaft.

[0029] Rotate the moving claw 4 and the fixed claw 5 with the pump shaft, and cooperate with the grinding assembly 3 to grind the pump shaft. After the processing is completed, the moving claw 4 and the fixed claw 5 release the clamping of the pump shaft. At this time, the two first telescopic rods 710 extend, and the pump shaft is pushed upward by the inclined top plate 711. When the position of the inclined top plate 711 is higher than the first guide rod 701 and the second guide rod 704, the pump shaft will roll into the collection box 2 under the guidance of the first guide rod 701 and the second guide rod 704 to achieve rapid blanking after the processing is completed, which is convenient for processing the next pump shaft.

[0030] Embodiment 2: Please refer to Figures 1-9 On the basis of Embodiment 1, the present invention provides a technical solution: A servo motor 802 is fixedly connected to the front surface of the first limiting plate 702. At the back of the servo motor 802 and on top of the roller group 801, a sweeping brush 803 is fixedly connected, and the sweeping brush 803 is fixedly connected to the output shaft of the servo motor 802. The outer side of the sweeping brush 803 is a bendable brush. The servo motor 802 can drive the sweeping brush 803 to rotate to push the pump shaft on the roller group 801 to move. When the sweeping brush 803 is stationary, the pump shaft will stay on top of the roller group 801 due to the frictional force of the brush. After the second telescopic rod 809 descends, the servo motor 802 sweeps the rightmost pump shaft out of the right side of the roller group 801 through the rotation of the sweeping brush 803, and then stops. After the second telescopic rod 809 rises, the sweeping brush 803 is driven to rotate and sweep.

[0031] An exhaust plate 804 is fixedly connected to the bottom of the first guide rod 701, and an air pump 805 is fixedly connected to the bottom of the exhaust plate 804.

[0032] An air suction box 806 is fixedly connected to the bottom of the roller group 801. An isolation filter screen 807 is fixedly connected inside the air suction box 806. The bottom of the air suction box 806 is fixedly connected to the air pump 805 through a pipeline.

[0033] During use, when the pump shaft is placed on top of the roller group 801, the servo motor 802 drives the sweeping brush 803 to rotate. The sweeping brush 803 continuously rotates to push the pump shaft to the right, making one side of the pump shaft fit with the edge of the limiting roller 808, which can prevent the pump shaft from tilting and improve the positioning accuracy. The sweeping brush 803 continues to be driven by the servo motor 802 to rotate, brushing the surface of the pump shaft. At the same time, the surface of the pump shaft fits with the roller group 801 and the limiting roller 808. While the sweeping brush 803 brushes the surface of the pump shaft, it also pushes the pump shaft to rotate. Since the air pump 805 extracts gas from the air suction box 806 and sends it to the exhaust plate 804 for discharge, the air suction box 806 will suck the debris remaining on the surface of the pump shaft due to the previous processing away from the surface of the pump shaft through the gap between the roller group 801.

[0034] When the pump shaft rolls towards the positions of the moving claw 4 and the fixed claw 5 under the guidance of the first guide rod 701 and the second guide rod 704, due to the protrusions on the surfaces of the first guide rod 701 and the second guide rod 704, the pump shaft intermittently impacts the first guide rod 701 and the second guide rod 704, causing the pump shaft to vibrate. This vibration can loosen the metal debris that may adhere to the surface of the pump shaft, and the air flow blown from the exhaust plate 804 blows the loosened metal debris away from the surface of the pump shaft. Moreover, when the pump shaft moves, it rolls, which enables the air flow to blow more comprehensively and blows the remaining metal debris on the surface of the pump shaft away from the surface of the pump shaft. This can prevent the debris from participating in the grinding process when the pump shaft is ground, embedding into the surface of the pump shaft during the grinding process, forming scratches or pits, and affecting the grinding quality and the final surface roughness of the pump shaft.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
