Description

Technical Field

[0001] This application relates to the field of production and assembly equipment for motors, and particularly to a faucet storage and water drainage rack. Background Art

[0002] The fixed part in a motor is called the stator, on which pairs of stationary main magnetic poles excited by direct current are installed; while the rotating part (rotor) is called the armature core, on which the armature winding is to be installed. After being energized, it generates an induced electromotive force, acts as a rotating magnetic field, and then generates an electromagnetic torque for energy conversion.

[0003] The motor stator is composed of a silicon steel core and a stator winding. Generally, the stator winding is a copper wire winding. After the copper wire winding is assembled onto the core, since the rotor will be inserted into the central hole of the stator during subsequent motor assembly and the gap between the stator and the rotor is small, if the copper wire winding is relatively loose, it will cause the rotor to touch the copper wire winding when inserted. During the operation of the motor product, the rotor is not allowed to touch the winding. Therefore, during the assembly process of the motor stator, there is a process of compacting and shaping the relatively loose copper wire winding, and the motor stator shaping machine is used to compact and shape the stator winding.

[0004] Generally, the stator shaping machine in the current technology first drives a support rod axially into the central hole of the stator by a servo motor, and then an independent cylinder pushes an arc-shaped plate located outside the stator to move radially towards the central axis of the stator. The arc-shaped plate presses against the copper wire winding, and the copper wire winding is supported by the above support rod inside. Thus, the copper wire winding is slightly flattened and appears tight and orderly.

[0005] Chinese Patent Application "An Energy-saving Motor Stator Shaping Machine", Application No.: 201921653656.8; discloses including a servo motor, a driving plate and a jaw. The driving plate can move up and down driven by the servo motor. The driving plate is provided with a driving inclined surface, and the driving inclined surface is adapted to a pulley at one end of the jaw, so that when the driving plate moves downward, it can use the driving inclined surface to push the jaw to perform a shaping action.

[0006] The existing shaping machines involve driving the movement strokes in multiple directions during the shaping process, either require multiple power devices, or need to design a transmission mechanism to transmit the driving force of the power device. Therefore, the structure of the shaping machine is a bit complex. Moreover, using multiple jaws to limit the shape of the stator requires a high synchronization of the jaw movement, which makes the shaping machine either have too high a manufacturing cost or limited shaping accuracy. Summary of the Invention

[0007] The technical problem to be solved by this application is to provide a shaping device for a motor stator, which has a simple overall structure, stable operation and high stroke accuracy during work.

[0008] The technical solution adopted in this application is as follows: A shaping device for a motor stator includes a frame. A moving slide plate, a shaping seat, a mounting base, and a fixing plate are sequentially arranged on the frame from top to bottom. The mounting base is installed above the fixing plate through a lower floating component, and the shaping seat is installed below the moving slide plate through an upper floating component. A servo motor is installed on the frame, and the servo motor is connected to the moving slide plate through a lead screw. An upper shaping groove is formed on the bottom surface of the shaping seat, and an upper shaping rod is connected below the moving slide plate. The upper shaping rod is located above the upper shaping groove. A lower shaping groove for installing the motor stator is formed on the surface of the mounting base. A through hole for the upper shaping rod to pass through is formed in the lower shaping groove, and the upper shaping rod is adapted to the through hole. When the servo motor works, it drives the shaping seat to move downward and contact the mounting base, and the upper shaping groove presses the motor stator.

[0009] Compared with the prior art, the advantages of this application are as follows: First, the upper shaping groove and the lower shaping groove after pressing are used to shape the outer shape of the motor stator. That is, the shaping of the outer contour of the motor stator is achieved by installing the motor stator in the lower shaping groove and then driving the shaping seat to move downward and press on the mounting base. At this time, the top surface of the upper shaping groove and the bottom surface of the lower shaping groove will squeeze the motor stator, thereby realizing the shaping of the motor stator and limiting and locking the motor stator. Then, when the moving slide plate continues to press downward, the shaping seat receives the force exerted on it by the mounting base, and the upper floating component contracts. The distance between the moving slide plate and the shaping seat changes. At this time, the upper shaping rod will gradually pass through the upper shaping groove to shape the central hole of the motor stator. In this application, the shaping and limiting of the outer contour of the motor stator are first achieved by pressing the shaping seat and the mounting base, and then the central hole of the motor stator is shaped. Only one servo motor is used in the working process of the entire shaping machine, and no additional transmission mechanism is involved. The structure of this application is simple. And during the movement of the shaping rod, it will be limited by the through hole in the lower shaping groove to ensure that the upper shaping rod moves along a predetermined movement trajectory, with stable operation and high stroke accuracy.

An upper shaping groove 11 is opened on the bottom surface of the shaping base 3, and an upper shaping rod 12 is connected below the moving slide plate 2. The upper shaping rod 12 is located above the upper shaping groove 11. A lower shaping groove 21 for installing the motor stator is opened on the surface of the mounting base 4. The outer shape of the motor stator is shaped by using the upper shaping groove 11 and the lower shaping groove 21 after pressing. That is, the shaping of the outer contour of the motor stator is achieved by installing the motor electronics in the lower shaping groove 21, and then driving the shaping base 3 to move down onto the mounting base 4. At this time, the top surface of the upper shaping groove 11 and the bottom surface of the lower shaping groove 21 will squeeze the motor stator, thereby realizing the shaping of the motor stator and limiting and locking the motor stator.

[0036] A through hole 9 for the upper shaping rod 12 to pass through is opened in the lower shaping groove 21. The upper shaping rod 12 is adapted to the through hole 9. The servo motor 6 works to drive the shaping base 3 to move downward to contact the mounting base 4, and the upper shaping groove 11 squeezes the motor stator. When the moving slide plate 2 continues to press down, the shaping base 3 receives the force exerted on it by the mounting base 4, and the upper floating component contracts. The distance between the moving slide plate 2 and the shaping base 3 changes. At this time, the upper shaping rod 12 will gradually pass through the upper shaping groove 11 to shape the central hole of the motor stator. In the present application, the shaping and limiting of the outer contour of the motor stator are first achieved by pressing the shaping base 3 and the mounting base 4, and then the shaping of the central hole of the motor electronics is carried out. Only one servo motor 6 is used in the whole working process of the shaping machine, and no additional transmission mechanism is involved. The structure of the present application is simple. And during the movement of the shaping rod, it will be limited by the through hole 9 in the lower shaping groove 21 to ensure that the upper shaping rod 12 moves along a predetermined movement trajectory, with stable operation and high stroke accuracy.

During the process of the installation base 4 moving downward under force, it will be limited by the through hole 9 in the lower shaping groove 21, ensuring that the shaping rod moves along a predetermined moving track, with stable operation and high stroke accuracy.

[0038] A lower guiding column 23 is installed on the fixing plate 5, and a lower positioning hole adapted to the lower guiding column 23 is provided on the installation base 4. At least part of the lower guiding column 23 is inserted into the lower positioning hole. During the process of the installation base 4 moving under force, it is restricted by the lower guiding column 23 and the lower positioning hole, ensuring that the installation base 4 can move axially without deviation and ensuring the movement accuracy of the installation base 4.

[0039] An upper guiding column 13 is installed on the moving slide plate 2, and an upper positioning hole 14 adapted to the upper guiding column 13 is provided on the shaping base 3. At least part of the upper guiding column 13 is inserted into the upper positioning hole 14. During the process of the shaping base 3 moving under force, it is restricted by the upper guiding column 13 and the upper positioning hole 14, ensuring that the shaping base 3 can move axially along the upper guiding column 13 without deviation and ensuring the movement accuracy of the shaping base 3.

[0040] At the four corners of the frame 1, moving guide columns 8 are vertically arranged. The four moving guide columns 8 pass through the moving slide plate 2, and the moving slide plate 2 moves up and down along the moving guide columns 8. In this application, the moving guide columns 8 passing through the moving slide plate 2 limit the movement of the moving slide plate 2 along a predetermined track.

The lower ejector rod 26 is coaxially arranged with the lower spring 25 where it is located; in the non-working state, the end of the lower ejector rod 26 is located inside the lower spring 25.

[0042] The upper floating component includes a plurality of upper springs 15, and the upper springs 15 are located between the moving slide plate 2 and the shaping base 3.

The upper ejector rod 16 is coaxially arranged with the upper spring 15 where it is located; in the non-working state, the end of the upper ejector rod 16 is located inside the upper spring 15.

[0043] In the working state, the upper floating component contracts, and the upper ejector rod 16 penetrates through the sizing seat 3; in the working state, the lower floating component contracts, and the lower ejector rod 26 penetrates through the mounting base 4. When the upper ejector rod 16 contacts the lower ejector rod 26, the moving slide plate 2 moves downward to the limit position at this time.
