[0007] Positioning and loading mechanism includes:

[0008] A first guide rod, which is fixedly connected to the top of the workbench and is located on the left side of the fixed claw;

[0009] a first limiting plate, the first limiting plate being fixedly connected to the front side of the first guide rod;

[0010] A first upper limit rod is fixedly connected to the back side of the first limit plate and is located at the top of the first guide rod.

[0011] Preferably, the left side of the movable claw is fixedly connected to a second guide rod, the back of the second guide rod is fixedly connected to a second limiting plate, and the front of the second limiting plate is located at the top of the second guide rod and is fixedly connected to a second upper limiting rod.

[0014] Preferably, the sweeping mechanism includes a roller group, which is fixedly connected to the top of the workbench on the left side of the first limit plate. The top of the workbench is located on the right side of the servo motor and is fixedly connected to a second telescopic rod, and the top of the second telescopic rod is movably connected to the limit roller.

[0015] Preferably, the front side of the first limiting plate is fixedly connected to a servo motor, the back side of the servo motor is located on the top of the roller group and is fixedly connected to a sweeping brush, and the sweeping brush is fixedly connected to the output shaft of the servo motor.

[0016] Preferably, the bottom of the first guide rod is fixedly connected to an exhaust plate, and the bottom of the exhaust plate is fixedly connected to an air pump.

[0017] Preferably, an air suction box is fixedly connected to the bottom of the roller group, an isolation filter is fixedly connected to the inside of the air suction box, and the bottom of the air suction box is fixedly connected to the air pump through a pipeline.

[0018] The present invention provides a special water pump shaft processing auxiliary feeding device. It has the following beneficial effects:

[0019] 1. This special water pump shaft processing auxiliary loading device places 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 allows the pressure sensor to move with the mobile claw to squeeze the pump shaft. The pressure sensor will detect that the pressure continues to increase, stop the mobile claw, and then allow the pump shaft to move to the corresponding position of the mobile claw and the fixed claw under the guidance of the first guide rod and the second guide rod. At this time, the mobile claw and the fixed claw can directly clamp the pump shaft to achieve rapid positioning of the pump shaft, thereby increasing the processing speed.

[0020] 2. This special water pump shaft processing auxiliary loading device extends the two first telescopic rods and pushes the pump shaft upward through the inclined top plate. When the position of the inclined top plate is higher than the first guide rod and the second guide rod, the pump shaft will roll into the collection frame under the guidance of the first guide rod and the second guide rod, thereby realizing rapid unloading after processing is completed, facilitating the processing of the next pump shaft, and thus improving the processing speed.

[0021] 3. This special water pump shaft processing auxiliary loading device places the pump shaft on the top of the roller group, allowing the sweeping brush to continuously rotate and push the pump shaft to the right, so that one side of the pump shaft fits into the edge of the limiting roller. This can prevent the pump shaft from tilting and cause pressure sensor sensing errors, thereby improving positioning accuracy and making positioning more accurate.

[0022] 4. The special water pump shaft processing auxiliary feeding device is continuously driven by the servo motor to rotate through the sweeping brush. The rotating sweeping brush will brush the surface of the pump shaft. At the same time, the surface of the pump shaft fits the roller group and the limit roller. The sweeping brush will push the pump shaft to rotate while brushing the surface of the pump shaft, allowing the suction box to absorb the debris left over from the previous step of processing from the surface of the pump shaft through the gap between the roller groups, which can improve the processing quality, avoid secondary processing, and increase the processing speed.

[0023] 5. The special water pump shaft processing auxiliary feeding device rolls the pump shaft 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 and then loosen the metal debris that may be contaminated on the pump shaft surface. The airflow blown out from the exhaust plate will blow it away from the pump shaft surface, blowing away the remaining metal debris on the pump shaft surface. This can improve the processing quality, avoid secondary processing, and increase the processing speed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0036] Example 1: Please refer to Figure 1-9 The present invention provides a technical solution: an auxiliary feeding device for processing a special water pump shaft, comprising a workbench 1, a grinding assembly 3 fixedly connected to the top of the workbench 1, a collecting frame 2 fixedly connected to the right side of the workbench 1, a fixed clamping claw 5 fixedly connected to the left side of the grinding assembly 3 at the top of the workbench 1, a movable clamping claw 4 movably connected to the back of the fixed clamping claw 5 at the top of the workbench 1, a driving screw 6 movably connected to the top of the workbench 1, and the driving screw 6 is movably connected to the movable clamping claw 4, a positioning feeding mechanism 7 fixedly connected to the left side of the fixed clamping claw 5 at the top of the workbench 1, and a sweeping mechanism 8 fixedly connected to the outer wall of the positioning feeding mechanism 7;

[0037] Positioning and feeding mechanism 7 includes:

[0038] A first guide rod 701, which is fixedly connected to the top of the workbench 1 and located on the left side of the fixed claw 5;

[0039] A first limiting plate 702, the first limiting plate 702 is fixedly connected to the front side of the first guide rod 701;

[0040] The first upper limit rod 703 is fixedly connected to the back side of the first limit plate 702 and is located on the top of the first guide rod 701 .

[0041] The left side of the movable claw 4 is fixedly connected to the second guide rod 704 , the back of the second guide rod 704 is fixedly connected to the second limiting plate 706 , and the front of the second limiting plate 706 is located at the top of the second guide rod 704 and is fixedly connected to the second upper limiting rod 705 .

[0042] The back of the second limiting plate 706 is fixedly connected to a pressure sensor 709, and the back of the second limiting plate 706 is movably connected to a pushing plate 708. The outer wall of the pushing plate 708 is fixedly connected to a torsion spring 707, and the torsion spring 707 is fixedly connected to the second limiting plate 706. The torsion spring 707 plays a role in transmitting force for the pushing plate 708. At the same time, when the pushing plate 708 can no longer push the pump shaft, and the pressure sensor 709 can still continue to push the pump shaft, the pushing plate 708 will rotate around the connection between it and the second limiting plate 706, and cause the torsion spring 707 to deform.

[0043] Inside the workbench 1 , a first telescopic rod 710 is fixedly connected to the back of the fixed claw 5 , and a first telescopic rod 710 is fixedly connected to the front of the movable claw 4 . The tops of the two first telescopic rods 710 are both fixedly connected to an inclined top plate 711 .

[0044] The sweeping mechanism 8 includes a roller group 801, which is fixedly connected to the top of the workbench 1 on the left side of the first limit plate 702. The top of the workbench 1 is fixedly connected to the right side of the servo motor 802 with a second telescopic rod 809, and the top of the second telescopic rod 809 is movably connected to a limit roller 808.

[0045] When in use, place the pump shaft to be processed on the top of the roller group 801, and the pump shaft will roll on the top of the roller group 801 until it fits with the limiting roller 808. The driving screw 6 will drive the moving claw 4 to move by rotating. The moving claw 4 will move with the second guide rod 704 during the movement. The pressure sensor 709 will move with the moving claw 4 through the second limiting plate 706 to squeeze the pump shaft, so that the other end of the pump shaft fits into the first limiting plate 702. The pump shaft cannot move at this time, and the pressure sensor 709 will detect that the pressure continues to increase. At this time, the driving screw 6 will stop rotating, and the moving claw 4 will stop moving. This can be applied to pump shafts of different specifications and sizes. When placing multiple pump shafts at a time, the moving claw 4 drives the second limiting plate 706 moves and pushes the ejecting plate 708 to move together through the second limit plate 706. The side of the ejecting plate 708 close to the first guide rod 701 will simultaneously push one side of multiple pump shafts. Under the elastic force of the torsion spring 707 resisting deformation, when one end of the longer shaft contacts the first limit plate 702, the ejecting plate 708 continues to be pushed, causing the ejecting plate 708 to rotate toward the outside of the second limit plate 706 and causing the torsion spring 707 to deform. At this time, the part of the ejecting 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 subsequently processed pump shaft close to the first limit plate 702.

[0046] Then the second telescopic rod 809 contracts, allowing the limiting roller 808 to descend, and the pump shaft will move to the corresponding position of the movable 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 movable claw 4 and the fixed claw 5 can directly clamp the pump shaft to achieve rapid positioning of the pump shaft.

[0047] The movable jaw 4 and the fixed jaw 5 are allowed to rotate with the pump shaft, and the pump shaft is ground in cooperation with the grinding assembly 3. After the processing is completed, the movable jaw 4 and the fixed jaw 5 release the clamping of the pump shaft. At this time, the two first telescopic rods 710 are extended, and the pump shaft is pushed upward through 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 frame 2 under the guidance of the first guide rod 701 and the second guide rod 704, so as to realize rapid unloading after the processing is completed, so as to facilitate the processing of the next pump shaft.

[0048] Example 2: Please refer to Figure 1-9 Based on the first embodiment, the present invention provides a technical solution:

[0049] The front of the first limit plate 702 is fixedly connected to a servo motor 802, and the back of the servo motor 802 is located at the top of the roller group 801 and is fixedly connected to a sweeping brush 803, 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 flexible brush. The servo motor 802 can control the rotation of the sweeping brush 803 to push the pump shaft on the roller group 801 to move. When the sweeping brush 803 is stationary, the friction force of the brush will allow the pump shaft to stay on the top of the roller group 801. When the second telescopic rod 809 is lowered, the servo motor 802 rotates the sweeping brush 803 to sweep the rightmost pump shaft out of the right side of the roller group 801, and then stops, allowing the second telescopic rod 809 to rise so that the sweeping brush 803 is driven to rotate and sweep.

[0050] 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 .

[0051] An air suction box 806 is fixedly connected to the bottom of the roller group 801, an isolation filter 807 is fixedly connected inside the air suction box 806, and the bottom of the air suction box 806 is fixedly connected to the air pump 805 through a pipeline.

[0052] During use, when the pump shaft is placed on the top of the roller group 801, the servo motor 802 is used to drive the sweeping brush 803 to rotate. The sweeping brush 803 will continuously rotate to push the pump shaft to the right, so that one side of the pump shaft fits against the edge of the limiting roller 808, which can prevent the pump shaft from tilting to improve the positioning accuracy. The sweeping brush 803 is continuously driven by the servo motor 802 to rotate, and the surface of the pump shaft is brushed. At the same time, the surface of the pump shaft fits against the roller group 801 and the limiting roller 808. The sweeping brush 803 brushes the surface of the pump shaft and pushes the pump shaft to rotate. Since the air pump 805 draws gas from the suction box 806 and sends it to the exhaust plate 804 for discharge, the suction box 806 will suck the debris remaining on the surface of the pump shaft due to the previous step of processing away from the surface of the pump shaft through the gap between the roller group 801.

[0053] When the pump shaft rolls toward the position of the movable claw 4 and the fixed claw 5 under the guidance of the first guide rod 701 and the second guide rod 704, the surface of the pump shaft passing through the first guide rod 701 and the second guide rod 704 will intermittently collide with the first guide rod 701 and the second guide rod 704 due to the protrusions, causing the pump shaft to vibrate and thereby loosen the metal debris that may be contaminated on the surface of the pump shaft, and the metal debris is blown away from the surface of the pump shaft by the air flow blown out from the exhaust plate 804. Moreover, the pump shaft moves in a rolling form when moving, which makes the air flow blow more comprehensively and blows away the metal debris remaining on the surface of the pump shaft from the surface of the pump shaft, thereby preventing the debris from participating in the grinding process when the pump shaft is being ground, and being embedded in the surface of the pump shaft during the grinding process, forming scratches or potholes, affecting the grinding quality and the final surface roughness of the pump shaft.

[0054] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
