Description

Technical Field

[0001] This utility model relates to the field of motor processing tooling technology, and to a tooling for impregnating an external rotor permanent magnet motor with paint, and particularly to a ground-guided movable tooling equipment for impregnating an external rotor permanent magnet motor with high operating efficiency and good operating safety. Background Technology

[0002] Traditionally, motor stators require aerial hoisting using a crane during the dip-coating process. Because motor stators are generally heavy and have long shafts, this method not only necessitates a large-tonnage crane but also places certain demands on the height of the production area. The suspended movement of the workpiece at height inevitably causes swaying and swinging, raising risks of disengagement and injury to objects or personnel. Furthermore, the dip-coating process is inefficient and unsuitable for mass production.

[0003] With the continuous upgrading of my country's industrialization and the popularization of permanent magnet motors, large external rotor permanent magnet motors are being selected by more and more industries, such as coal mines and docks. The increase in market demand and the standardization of the industry have made the traditional impregnation operation method gradually unable to keep up with the times.

[0004] Therefore, developing a device for impregnating external rotor permanent magnet motors with high operating efficiency and good operating safety is of great practical significance. Utility Model Content

[0005] Due to the aforementioned defects in the existing technology, this utility model provides a device for impregnating an external rotor permanent magnet motor with high operating efficiency and good operating safety, overcoming the defects of poor operating safety and low operating efficiency of the device for impregnating an external rotor permanent magnet motor.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tooling for impregnating an external rotor permanent magnet motor includes a platform substrate;

[0008] The bottom of the platform substrate is provided with two roller sets, and each roller set includes multiple arc rollers arranged in a row;

[0009] The platform base plate has a through hole in the middle for the external rotor permanent magnet motor to pass through. Two column beams are symmetrically installed on both sides of the platform base plate corresponding to the through hole. A lifting motor and a winch are installed on each column beam. The drive shaft of the lifting motor is coaxially connected to the winch. A steel wire rope is wound on the winch and a hook is installed on the free end of the steel wire rope.

[0010] Two clamping devices are symmetrically installed on both sides of the corresponding through hole on the platform substrate.

[0011] The operation of the above-mentioned external rotor permanent magnet motor impregnation fixture is as follows:

[0012] When performing the dipping operation, simply hang the hook on the ground and operate the winch to pull up the clamping device below to hold the stator workpiece. At this time, the upper end of the workpiece is taut by ropes and the lower end is fixed by the clamping device, so the workpiece will not sway during the movement. The operator can stay away from the operation area to avoid the possibility of accidental injury. After the tooling platform reaches the position of the dipping tank, the clamp is released, and then the upper winch rotates to slowly lower the stator workpiece into the dipping tank. The whole process basically does not require operators to make manual adjustments to the position and height, avoiding misjudgments that may occur due to visual judgment of distance and height, and effectively avoiding damage to items, dipping equipment and workpieces.

[0013] This utility model of an external rotor permanent magnet motor impregnation fixture has a reasonable structural design. The fixture can not only move on the working surface using roller assembly, but also use a winch, wire rope and hook to lift the stator workpiece. At the same time, two clamping devices can fix the bottom of the stator workpiece, which can ensure the stability of the stator workpiece when the fixture moves. After reaching the working position, the clamping devices are released, and the stator workpiece is lowered using the winch. The stator workpiece falls into the impregnation tank through the through hole for impregnation. It has good application prospects.

[0014] As a preferred technical solution:

[0015] As described above, the external rotor permanent magnet motor impregnation fixture has two parallel and spaced ground guide rails laid on the mounting surface. These ground guide rails are matched with arc-shaped rollers, and the distance between the two ground guide rails matches the distance between the roller sets. An arc-shaped groove, matching the arc-shaped rollers, is machined in the middle of the ground guide rails. The external rotor permanent magnet motor impregnation fixture moves linearly within the groove via the rollers. The arc-shaped rollers engage with the arc-shaped grooves on the ground guide rails, allowing the fixture to move linearly along the ground guide rails.

[0016] As described above, in the external rotor permanent magnet motor impregnation fixture, two roller seats are fixed at the bottom of the platform base plate, the roller assembly is mounted on the roller seats, multiple roller shafts are mounted on the roller seats, and the arc-shaped roller set is fixed on the roller shafts.

[0017] As described above, in the external rotor permanent magnet motor impregnation fixture, a steel cable guide wheel is also installed on the column beam, and the free end of the steel wire rope passes through the steel cable guide wheel;

[0018] Two steel cable guide wheels are installed on the inside of the two column beams.

[0019] As described above, in the external rotor permanent magnet motor impregnation fixture, the lifting motor is fixed to the column beam via a motor mounting base;

[0020] The winch is connected to the top plate of the column beam via a winch shaft, and the winch is coaxially connected to the drive shaft of the hoisting motor to achieve transmission for winding and unwinding the steel cable.

[0021] The above-described external rotor permanent magnet motor impregnation fixture includes a clamping device comprising a clamping cylinder and a clamping claw mounted on the drive end of the clamping cylinder.

[0022] The two clamping cylinders are located on the same straight line and their drive ends are close to each other.

[0023] As described above, in the external rotor permanent magnet motor impregnation fixture, the clamping cylinder is fixedly mounted on the platform base plate via a cylinder mounting seat. The clamping cylinder and the cylinder mounting seat are fixedly connected by bolts.

[0024] As described above, in the varnishing fixture for an external rotor permanent magnet motor, the gripper is V-shaped.

[0025] The two clamping cylinders work in sync to lock the center of the lower end of the external rotor permanent magnet motor.

[0026] As described above, in the varnishing fixture for an external rotor permanent magnet motor, the angle between the line connecting the two column beams and the line connecting the two clamping devices is 45°.

[0027] As described above, in the external rotor permanent magnet motor impregnation fixture, the platform base plate is welded to the column beam;

[0028] The platform substrate is welded to the roller seat.

[0029] The aforementioned external rotor permanent magnet motor impregnation fixture can also be used with a stator positioning tray, which is equipped with a conical positioning cylinder.

[0030] A control console can be installed on the platform substrate to control the movement, lifting and other operations of the external rotor permanent magnet motor impregnation fixture. Alternatively, the control console and the control unit of the impregnation equipment can be modified and merged into one integrated operation. These are all existing mature technologies.

[0031] The above technical solution is only one feasible technical solution of this utility model. The protection scope of this utility model is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0032] The above-mentioned utility model has the following advantages or beneficial effects:

[0034] (2) The external rotor permanent magnet motor impregnation fixture of this utility model makes the impregnation process safer and more conducive to the implementation of operating procedures by positioning the workpiece through the fixture platform, and the work efficiency will also be greatly improved.

[0036] (4) The external rotor permanent magnet motor impregnation fixture of this utility model greatly avoids the damage to the workpiece and equipment caused by collisions and falls that may occur during the process. It has good operational safety and good application prospects. Attached Figure Description
