Description

Technical Field

[0001] The utility model relates to the technical field of water pump impeller detection, in particular to a water pump impeller dynamic balance detection device. Background Art

[0002] The dynamic balancing test of the water pump impeller is an important quality control process, which can ensure the stability and efficiency of the water pump during operation. The dynamic balancing machine can fix the impeller and rotate it to detect the imbalance. The dynamic balancing method of the water pump impeller is usually adopted. Some highly automated detection devices are equipped with a calibration unit, and its mobile limit structure includes guide rails, positioning pins, fixtures and other components to achieve precise control and positioning of the calibration, and can automatically adjust the rotation of the impeller and add weight to calibrate the impeller. Some existing dynamic balancing detection units have a larger protective net installed on the outside of the working platform, and a mesh plate that can be moved up and down is installed facing the direction of the operators to prevent the water pump impeller from detaching and popping out during the detection process and causing harm to the operators. However, the overall space occupied by the equipment is relatively large. When debugging the detection unit and the impeller, it is necessary to drive the movable mesh plate to be moved away by an electric device. When adding weight or debugging the impeller, it is necessary to wait until the impeller stops rotating before operating. This is time-consuming as a whole and is not convenient for improving the efficiency of water pump impeller detection and weight balancing. Some automatic calibration units are also arranged inside the protective net. If the impeller detaches, it may cause impact on the calibration unit and cause damage to it, which is inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 6 In an embodiment of the utility model, a water pump impeller dynamic balance detection device includes a detection mechanism 10, and the detection mechanism 10 includes a base 11. An operating platform 12 is fixedly connected to the top of the base 11. A calibration unit 13 is slidably connected to the top of the operating platform 12 through a guide rail. A detection unit 14 is fixedly connected to the top of the operating platform 12. A limit plate 15 is slidably connected to the top of the operating platform 12. A protective shell 151 is movably connected to the top of the limit plate 15. The protective shell 151 is internally rotatably connected to a protective shell 2 152. A vertical rod 16 is slidably connected to the inner top surface of the protective shell 2 152. The bottom end of the vertical rod 16 is rotatably connected to a rubber pad 161. A control module 17 for regulating the protective shell 151 and the protective shell 2 152 is provided on the top of the operating platform 12.

[0023] Specifically, the protective shell 151 and the protective shell 2 152 are connected by rotating at the top of the limit plate 15. Before the test, the motor 2 174 is started to rotate the protective shell 151 so that its opening is aligned with the calibration unit 13, and the protective shell 2 152 is rotated to cooperate with the protective shell 1 151 to cover the detection unit 14 to prevent the water pump impeller body 20 from detaching and popping out to cause damage to the calibration unit 13 and the workers. The protection is more stable. The electric push rod 166 is started to make the rubber pad 161 and the water pump impeller body 20 stick to it to stop rotating faster, saving detection and calibration time. After the protective shell 2 152 is rotated into the protective shell 1 151, the calibration unit 13 can be used to add weight to the water pump impeller body 20, which is convenient to use.

[0024] Embodiment 1

[0025] like Figure 1-4 As shown, in this embodiment, a circular plate 162 is fixedly connected to the bottom end of the vertical rod 16, and the circular plate 162 is rotatably connected to the inside of the rubber pad 161. A torsion spring 163 is fixedly connected between the circular plate 162 and the rubber pad 161.

The output end of the electric push rod 166 passes through the limit shell 165 and is fixedly connected to the limit block 164.

[0026] In this embodiment, the rubber pad 161 is rotationally limited by the circular plate 162 in cooperation with the vertical rod 16. After the rubber pad 161 is driven by the vertical rod 16 to contact the water pump impeller body 20, the rotation of the water pump impeller body 20 is first delayed by contact and friction. The water pump impeller body 20 rubs the rubber pad 161 to rotate for buffering until it cannot rotate, giving the rubber pad 161 a buffering space to reduce the impact on the water pump impeller body 20. After the rubber pad 161 is separated from the water pump impeller body 20, the torsion spring 163 drives the rubber pad 161 to reset, and the limiting shell 165 limits the limiting block 164 to achieve sliding limitation of the vertical rod 16 and the rubber pad 161, so that the rubber pad 161 can contact or separate from the water pump impeller body 20, and the moving electric push rod 166 can adjust the position of the vertical rod 16 and the rubber pad 161.

[0027] like Figure 2-5 As shown, in this embodiment, a curved plate 154 is fixedly connected to the bottom of the protective shell 151 , a limiting groove 155 is provided on the top of the limiting plate 15 , and the curved plate 154 is slidably connected to the limiting groove 155 .

[0028] During specific implementation, the arc plate 154 is limited by the limiting groove 155 , thereby slidingly limiting the protective shell 151 , so that the protective shell 151 can be rotated around the central axis of the detection unit 14 to adjust its position.

[0029] Embodiment 2

[0030] On the basis of the first embodiment, in order to automatically adjust the positions of the protective shell 1 151 and the protective shell 2 152 during the detection process, the detection and calibration efficiency of the water pump impeller body 20 is improved.

[0031] like Figure 1-6 As shown, in this embodiment, the control module 17 includes a motor 172 fixedly connected to the outer wall of the operating platform 12, a slide groove 121 is provided on the top of the operating platform 12, a slider 153 is fixedly connected to the bottom of the limit plate 15, the slider 153 is slidably connected to the inside of the slide groove 121, and a one-way screw rod 171 is rotatably connected between the two ends of the inside of the slide groove 121, the one-way screw rod 171 passes through the slider 153 and is screwed together with it, and the output end of the motor 172 passes through the operating platform 12 and is connected to the adjacent one-way screw rod 171. The end is fixedly connected, an incomplete gear ring 173 is fixedly connected to the outer wall of the protective shell 151, the top of the limiting plate 15 is fixedly connected to the motor 2 174, the output end of the motor 2 174 is fixedly sleeved with a gear 175, the gear 175 is meshed with the incomplete gear ring 173, the top of the protective shell 2 152 is fixedly connected to the shaft block 176, the shaft block 176 is rotatably connected to the protective shell 151, the top of the protective shell 151 is fixedly connected to the motor 3 177, the output end of the motor 3 177 passes through the protective shell 151 and is fixedly connected to the shaft block 176.

[0032] During specific implementation, the sliding limit of the limit plate 15 is achieved by limiting the slider 153 through the slide groove 121. The starting motor 172 can drive the one-way screw 171 to rotate, thereby driving the limit plate 15 to move, so that the limit plate 15 can drive the protective shell 151 and the protective shell 2 152 to move away from the top of the detection unit 14, which is more convenient for loading and unloading the water pump impeller body 20 and debugging the detection unit 14. The starting motor 2 174 can drive the gear 175 to rotate, and the protective shell 151 is driven to rotate through the transmission of the gear 175 and the incomplete gear ring 173 to adjust the position of the protective shell 151. The protective shell 151 and the protective shell 2 152 are rotatably connected through the shaft block 176. The starting motor 3 177 can drive the protective shell 2 152 to rotate.
