[0002] In the manufacturing and assembly process of the booster pump, the rotor is an extremely critical component.

[0023] like Figures 1 to 6 As shown, an embodiment of the present invention provides a boost pump rotor surface treatment device, which includes a bracket 110, a transmission member, a grinding rod 160 and an adjustment control.

[0024] The bracket 110 can be placed on the ground or on an operating table. The bracket 110 includes a bottom plate 111 and a support ring 112. The bottom plate 111 is horizontally arranged. The support ring 112 is fixedly arranged on the bottom plate 111. The axis of the support ring 112 is horizontally arranged. A positioning ring 140 is rotatably connected to the support ring 112. The positioning ring 140 is coaxially arranged with the support ring 112. The bracket 110 is provided with a first clamping member and a second clamping member. The first clamping member clamps the first transmission ring 120, and the second clamping member clamps the second transmission ring 130. Under the action of the first clamping member and the second clamping member, the positioning ring 140, the first transmission ring 120 and the second transmission ring 130 are in a coaxial state. In the axial direction of the positioning ring 140, the second transmission ring 130, the first transmission ring 120 and the positioning ring 140 are arranged at intervals. A connecting rod 180 is connected to the rotor 190, and the rotor 190 is a rotor 190 after preliminary processing. The connecting rod 180 is coaxially connected to the second transmission ring 130, and the connecting rod 180 and the second transmission ring 130 can rotate relative to each other. However, there is resistance when the connecting rod 180 and the second transmission ring 130 rotate relative to each other. When the second transmission ring 130 rotates rapidly, the connecting rod 180 rotates gradually, and the rotation speed of the connecting rod 180 is lower than the rotation speed of the second transmission ring 130; as the second transmission ring 130 rotates, the rotation speed of the connecting rod 180 gradually increases until the connecting rod 180 and the second transmission ring 130 rotate synchronously. A driving source is provided on the bracket 110, and the driving source is used to drive the positioning ring 140 to rotate. Specifically, the driving source is a driving motor 150, and the driving motor 150 is fixedly connected to the base plate 111. A driving gear is fixedly provided on the power output shaft of the driving motor 150, and an annular gear is provided on the outer peripheral wall of the positioning ring 140. The driving gear is always engaged with the annular gear of the positioning ring 140. When the driving motor 150 is started, the positioning ring 140 starts to rotate, and the driving motor 150 can drive the positioning ring 140 to rotate forward or reverse.

[0025] Two groups of transmission members are provided, one of which is provided between the positioning ring 140 and the first transmission ring 120, and the other is provided between the first transmission ring 120 and the second transmission ring 130. By providing two groups of transmission members, when the positioning ring 140 rotates, the first transmission ring 120 and the second transmission ring 130 rotate at the same time. In the initial state, under the action of the first clamping member and the second clamping member, the first transmission ring 120, the second transmission ring 130 and the positioning ring 140 are in a coaxial state. In the initial stage of the rotation of the positioning ring 140, the first transmission ring 120, the second transmission ring 130 and the positioning ring 140 rotate coaxially. When the second transmission ring 130 rotates, the second transmission ring 120 The dynamic ring 130 gradually drives the connecting rod 180 to rotate, and the connecting rod 180 gradually drives the rotor 190 to rotate. As the second transmission ring 130 continues to rotate, the connecting rod 180 gradually rotates synchronously with the second transmission ring 130. If there are irregular positions on the surface of the rotor 190, when the connecting rod 180 and the second transmission ring 130 rotate synchronously, the rotor 190 jumps. The jumping of the rotor 190 refers to the offset between the rotation axis of the rotor 190 and the axis of the connecting rod 180. When the rotor 190 jumps, the second transmission ring 130 jumps through the transmission of the connecting rod 180. After the second transmission ring 130 jumps, it is no longer coaxial with the first transmission ring 120.

[0026] The grinding rod 160 is fixedly connected to the first transmission ring 120, and the grinding rod 160 is spaced apart from the rotor 190. In the initial state, the grinding rod 160 is not in direct contact with the rotor 190, and when the first transmission ring 120 rotates, the grinding rod 160 does not grind the rotor 190. When the rotor 190 beats, the rotation speed of the rotor 190 is the same as the rotation speed of the first transmission ring 120, and the outer peripheral wall of the rotor 190 is in direct contact with the grinding rod 160. At this time, the beating of the rotor 190 is transmitted through the grinding rod 160, so that the first transmission ring 120 beats.

[0027] The adjustment control is used to adjust the driving source to reversely drive the positioning ring 140 to rotate when the connecting rod 180 and the second transmission ring 130 rotate synchronously. When the positioning ring 140 rotates in the opposite direction, the first transmission ring 120 and the second transmission ring 130 rotate in the opposite direction at the same time. Since the rotor 190 and the connecting rod 180 have rotational inertia, the rotation direction of the rotor 190 is opposite to the rotation direction of the second transmission ring 130, so that the connecting rod 180 and the second transmission ring 130 rotate relative to each other, and the first transmission ring 120 and the rotor 190 rotate relative to each other, and the polishing rod 160 polishes the surface of the rotor 190.

[0028] A booster pump rotor surface treatment device of the present invention needs to perform fine processing on the rotor 190 after the initial processing of the rotor 190. First, the rotor 190 is connected to the connecting rod 180, and the connecting rod 180 is connected to the second transmission ring 130. Under the action of the driving source, the driving source drives the positioning ring 140 to rotate. When the positioning ring 140 rotates, it is driven by the transmission member. The first transmission ring 120 and the second transmission ring 130 rotate at the same time. In the initial stage of the rotation of the positioning ring 140, the grinding rod 160 is in a state of not contacting the outer peripheral side wall of the rotor 190. At this time, the connecting rod 180 and the second transmission ring 130 have the same rotation direction and different rotation speeds. As the second transmission ring 130 continues to rotate, the connecting rod 180 and the second transmission ring 130 gradually rotate synchronously. When the connecting rod 180 and the second transmission ring 130 rotate synchronously, if the rotor 190 There are irregular positions on the surface, and the rotor 190 will jump during the rotation process. The rotor 190 will drive the connecting rod 180 to jump synchronously, and the connecting rod 180 will drive the second transmission ring 130 to jump synchronously. When the rotor 190 jumps, the outer peripheral wall of the rotor 190 contacts the polishing rod 160, causing the first transmission ring 120 to jump. At this time, the control unit adjusts the driving source to reversely drive the positioning ring 140 to rotate, so that the connecting rod 180 and the second transmission ring 130 rotate relatively. At this time, the polishing rod 160 polishes the surface of the rotor 190; thereby achieving the polishing of the rotor 190 during the jumping and rotation process, until the connecting rod 180 and the second transmission ring 130 rotate synchronously, the rotor 190 does not jump, ensuring that the polishing rod 160 can polish the rotor 190 into a perfect circle, and then ensuring that the polished rotor 190 can meet the working requirements.

[0029] In one embodiment, one end of the connecting rod 180 is fixedly connected to the rotor 190, and the other end of the connecting rod 180 is sleeved with a spacer 170, the inner diameter of the spacer 170 is the same as the outer diameter of the connecting rod 180, and the spacer 170 is coaxially fixedly connected with the second transmission ring 130. When the spacer 170 is sleeved on the connecting rod 180, when the second transmission ring 130 rotates, the spacer 170 and the connecting rod 180 will move relative to each other. After the second transmission ring 130 rotates for a certain period of time, the connecting rod 180 and the second transmission ring 130 are driven by the spacer 170, so that the connecting rod 180 rotates synchronously with the second transmission ring 130. When the second transmission ring 130 rotates in the opposite direction, due to the rotational inertia of the connecting rod 180 and the rotor 190, the connecting rod 180 continues to rotate in the original direction, and the rotation speed gradually decreases. At this time, the spacer 170 and the connecting rod 180 move relative to each other.

[0030] In one embodiment, the first clamping member includes a plurality of first clamping rods 210, and the plurality of first clamping rods 210 are evenly distributed along the circumferential direction of the first transmission ring 120.

Further, the length of the second clamping rod 240 is greater than the length of the first clamping rod 210, and the diameter of the first transmission ring 120 is smaller than the diameter of the second transmission ring 130, and the first guide rail 220 and the second guide rail 250 on the support ring 112 are arranged at intervals to ensure that the second support rod does not squeeze the first transmission ring 120.
