Description

Technical Field

[0001] The utility model relates to the technical field of brushless water pump processing, in particular to a positioning tooling for brushless water pump processing. Background Technique

[0002] A brushless water pump, that is, a brushless DC pump, is a mechanical device that uses direct current (usually 4.5V - 24V) to drive a brushless motor to operate, and then increases the liquid pressure through the rotation of the impeller to achieve liquid transmission. The working principle of the brushless water pump is based on the combination of a brushless DC motor and a pump. The brushless motor drives the rotor equipped with a permanent magnet to rotate through the electromagnetic force generated after the stator coil is energized, without the need for a traditional brush and commutator for commutation, reducing friction loss and improving efficiency and lifespan. The pump part generates centrifugal force through the rotation of the impeller, sucks the liquid into the pump body and compresses and discharges it, forming the flow of the liquid. When processing a brushless water pump, it needs to be positioned, but the existing positioning tooling needs to be fixed manually, the operation is relatively cumbersome, and there are certain limitations. Therefore, it is necessary to design a positioning tooling for brushless water pump processing to solve the problem. Summary of the Invention

A main board is arranged inside the main body, and a trigger module is arranged at the top of the main board. A screw rod is rotatably connected inside the main body, and a moving block is threadedly connected to the outside of the screw rod. A connecting plate is fixedly installed at the top of the moving block, and a support column is connected and installed at the top of the connecting plate. A cross bar is connected to the top of the support column. A push rod motor is arranged inside the cross bar, and an output shaft of the push rod motor is connected with a pressing block.

[0006] Preferably, there are several positioning blocks, and they are designed in a square structure. The positioning blocks are distributed in a circular array, which can be applicable to the bottom plates of various models of brushless water pumps and position them from the outside.

[0007] Preferably, the number of the trigger modules is the same as that of the positioning blocks and the positions correspond. The position and number of the positioning blocks in contact with the brushless water pump are calculated according to the trigger modules.

[0008] Preferably, there are two groups of the screws, two in each group, and both are electric screws with motors, which are used to control the movement of the cross bar. Dust-proof pads are laid on the tops of the screws to play a protective role.

[0009] Preferably, there are several pressing blocks, and their positions correspond to those of the triggering module. The number and positions of the pressing blocks to be used can be determined according to the triggering module.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Embodiment: Refer to Figures 1-3, A positioning tooling for the processing of brushless water pumps, including a main body 1. A lifting rod 2 is slidably connected inside the main body 1, and a positioning block 3 is fixedly installed at the top of the lifting rod 2. There are several positioning blocks 3, and they are designed in a square structure. The positioning blocks 3 are distributed in an annular array, which can be applicable to the bottom plates of various models of brushless water pumps and position them from the outside. A compression spring 4 is fixedly installed at the bottom of the positioning block 3, and the compression spring 4 is sleeved outside the lifting rod 2. A main board 5 is arranged inside the main body 1, and a trigger module 6 is arranged at the top of the main board 5. The number of trigger modules 6 is the same as that of the positioning blocks 3 and the positions correspond. According to the trigger module 6, the position and number of the positioning blocks 3 in contact with the brushless water pump are calculated. A screw rod 7 is rotatably connected inside the main body 1, and a moving block 8 is connected to the outside of the screw rod 7 through a thread. A connecting plate 9 is fixedly installed at the top of the moving block 8, and a support column 10 is connected and installed at the top end of the connecting plate 9. A cross bar 11 is connected to the top end of the support column 10. There are two groups of screw rods 7, two in each group, and they are all electric screw rods with motors, used to control the movement of the cross bar 11. Dust-proof pads are laid at the top ends of the screw rods 7 to play a protective role. A push rod motor 12 is arranged inside the cross bar 11, and a pressing block 13 is connected to the output shaft of the push rod motor 12. There are several pressing blocks 13, and their positions correspond to those of the trigger modules 6. The number and position of the pressing blocks 13 needed can be determined according to the trigger module 6. The trigger module 6 is connected to the screw rod 7 and the push rod motor 12 through a circuit, used to control the position of the cross bar 11 moving and the number and position of the pressing blocks 13 required to descend.

[0019] Working principle: When in use, place the brushless water pump on the positioning block 3. The positioning block 3 contacts the base of the brushless water pump and causes it to descend. At the same time, the compression spring 4 contracts. At this time, the positioning block 3 positions the brushless water pump from the outside. Then, the lifting rod 2 connected to the positioning block 3 descends and contacts the trigger module 6. The main board 5 calculates the position where the base of the brushless water pump is located, thereby controlling the cross bar 11 to move to the outer circle of the base and turning on the push rod motor 12 to extend the pressing blocks 13 at the corresponding positions to fix the base of the brushless water pump from above.
