Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automatic material dispensing, and in particular relates to an automatic dispensing mechanism for a plastic stator tooling. Background Art
[0002] The stator plays a vital role when the motor is running. First, it provides mechanical support and protection for the motor to ensure that the motor will not be damaged by vibration during operation. Secondly, the coil in the stator will generate a magnetic field after the current is passed through it, which interacts with the magnetic field of the rotor to generate torque, thereby driving the rotor to rotate. In addition, the stator can also realize the control function of the motor. By changing the size and direction of the current, the parameters such as the rotation speed, direction and torque of the motor can be controlled. The stator winding plays a key role in the motor. When the current passes through the stator winding, it generates a magnetic field. This magnetic field interacts with the rotor magnetic field to generate a rotational torque, thereby driving the motor to rotate.
[0003] At present, the traditional stator tooling removal process mostly relies on manual operation, which is not only inefficient, but also has problems such as large operating errors and high labor intensity of workers. In addition, the installation of the stator frame will cause the position of the stator frame to shake and shift during winding, thereby reducing the precision of winding. Utility Model Content
[0004] The utility model aims to provide a plastic stator tooling automatic dialing mechanism to solve the above problems in the prior art.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A plastic stator tool automatic extraction mechanism comprises a base and a stator frame, wherein the base is detachably connected with a plurality of clamping tools, wherein the clamping tools stably clamp the stator frame, wherein a lower clamping block and an upper clamping block are installed in the clamping tools, and the stator frame is sleeved between the lower clamping block and the upper clamping block;
[0007] Two sets of material-dispensing mechanisms are installed on one side of the base, and the material-dispensing mechanisms are used to automatically dispense the stator frame on the clamping tooling;
[0008] A tail top mechanism is provided on one side of the clamping tool, and the tail top mechanism is used to open the clamping tool to limit the displacement of the stator frame.
[0009] Furthermore, notch grooves are symmetrically provided on both sides of the tail end of the clamping tool, and a plurality of square card slots are provided on the top of the base, and the notch grooves are card-mounted on the square card slots.
[0010] Furthermore, the material shifting mechanism includes a support arm and a cylinder body, the support arm is fixedly connected to the side wall of the base, the cylinder body is fixedly installed on one side of the support arm, a push rod is provided inside the cylinder body, a fixed head is provided at one end of the push rod, a corner slider is fixed on the fixed head, an assembly plate is fixed above the corner slider, and a material shifting fork is fixedly connected to the assembly plate.
[0011] In the above scheme, high-pressure gas is introduced into the cylinder body to cause the push rod to displace. Since the corner slider is fixedly connected to the push rod, the displacement of the synchronous push rod drives the corner slider to displace, that is, the assembly plate also displaces with the corner slider. At this time, when the corner slider displaces outward, the assembly plate synchronously drives multiple material shifting forks to displace, so that the stator frame on each clamping tool can be quickly removed at the same time under the action of the material shifting fork.
[0012] Furthermore, the material shifting fork is in a U-shaped structure.
[0013] In the above scheme, the U-arms of the shifting fork are distributed on both sides of the lower clamping block and the upper clamping block. In this way, when the assembly plate synchronously drives multiple shifting forks to move, the shifting forks can be evenly forcefully shifted out of the stator frame sleeved on the lower clamping block and the upper clamping block, making the stator frame fall off more smoothly without causing jamming.
[0014] Furthermore, a square block is fixedly mounted on the side wall of the corner slider, a buffer cylinder is mounted on the side of the cylinder body, and a buffer column is mounted in the buffer cylinder.
[0015] In the above scheme, high-pressure gas is introduced into the cylinder body, the push rod is displaced, and the corner slider is displaced outward. The corner slider will simultaneously drive the square block to displace, and the square block will contact and impact the buffer column. The buffer column effectively reduces the energy transfer caused by the impact, reduces noise, and improves the stability of the equipment.
[0016] Furthermore, the tail top mechanism comprises a fitting block, and the fitting block is symmetrically installed with limit blocks above and below. The clamping fixture is provided with a hinge hole, and the tail end of the upper clamping block is connected to the hinge hole through a bolt hinge, and the tail end of the lower clamping block is provided with a circular joint, wherein the circular joint is rotatably connected to the upper clamping block, and the lower clamping block and the upper clamping block are provided with corner openings, and a support block is fixed in the middle of the fitting block.
[0017] In the above scheme, when the expansion block is inserted into the corner opening, since the tail end of the upper clamping block is connected to the hinge hole by a bolt hinge, the upper clamping block will rotate upward, and the lower clamping block will also rotate downward under the rotating connection of the circular joint, that is, the expansion block expands the lower clamping block and the upper clamping block, thereby further stabilizing and limiting the stability of the stator frame. When the stator frame does not deviate and shake, the setting of the tail top mechanism improves the precision of winding during the winding process.
[0018] Furthermore, the lower clamping block and the upper clamping block are provided with a limiting sleeve on their peripheries, which is used to limit the maximum rotation angle of the lower clamping block and the upper clamping block, and the stator frame will be in contact with and aligned with the surface of the limiting sleeve when installed.
[0019] Furthermore, a mounting end is installed at the tail end of the bonding block.
[0020] In the above scheme, the part of the mounting end is used for connecting an external translation push mechanism, which is responsible for horizontally driving the tail top mechanism to automatically move, thereby realizing automatic pushing and displacement of the tail top mechanism, and improving the degree of automation of the overall equipment.
[0021] The technical solution of the utility model has the following beneficial effects:
[0022] 1. The material-dispensing mechanism is used to automatically dispense the stator frame on the clamping fixture. The assembly plate synchronously drives multiple material-dispensing forks to move. In this way, the stator frames on each clamping fixture can be quickly removed at the same time under the action of the material-dispensing forks. There is no need to remove them one by one manually. The equipment has a high degree of automation and integration, which significantly improves the speed and efficiency of material removal and is suitable for large-scale stator frame winding production.
[0023] 2. The tail top mechanism is used to open the clamping tooling to limit the displacement of the stator frame and realize the rapid clamping of the stator frame. The opening block is inserted into the corner, the upper clamping block will rotate upward, and the lower clamping block will rotate downward, that is, the opening block opens the lower clamping block and the upper clamping block, which further stabilizes and limits the stability of the stator frame. When the stator frame does not deviate and shake, the setting of the tail top mechanism improves the precision of winding during the winding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0035] Embodiment 1:
[0036] refer to Figure 1 A plastic stator tool automatic dispensing mechanism includes a base 10 and a stator frame 17. The base 10 is detachably connected with a plurality of clamping tools 12. The clamping tools 12 stably clamp the stator frame 17. A lower clamping block 14 and an upper clamping block 15 are installed in the clamping tool 12. The stator frame 17 is sleeved between the lower clamping block 14 and the upper clamping block 15. The stator frame 17 is sleeved between the lower clamping block 14 and the upper clamping block 15 and is placed by a mechanical arm or manually. The purpose of the stator frame 17 being sleeved between the lower clamping block 14 and the upper clamping block 15 is to perform winding, which is performed by a special winding mechanism. After the winding is completed, the stator frame 17 is removed.
[0037] Further references Figure 2The tail end of the clamping tool 12 is symmetrically provided with notch grooves 13 on both sides, and the top of the base 10 is provided with a plurality of square slots 11, and the notch grooves 13 are mounted on the square slots 11. The notch grooves 13 of the clamping tool 12 are aligned above the square slots 11 and the clamping tool 12 is pressed downward so that the notch grooves 13 are nested in the square slots 11. The structures of the two are matched so that the clamping tool 12 cannot rotate inside the square slots 11, thereby stabilizing the installation of the clamping tool 12. The plug-in nesting method is adopted to facilitate the maintenance, upgrade or replacement of the clamping tool 12 and improve the flexibility of the design.
[0038] refer to Figure 3-Figure 6 Two sets of material shifting mechanisms are installed on one side of the base 10, and the material shifting mechanism is used to automatically shift out the stator frame 17 on the clamping tool 12; the material shifting mechanism includes a support arm 25 and a cylinder body 26, the support arm 25 is fixedly connected to the side wall of the base 10, and the cylinder body 26 is fixedly installed on one side of the support arm 25. A push rod 27 is provided inside the cylinder body 26, and a fixed head 28 is provided at one end of the push rod 27. A corner slider 29 is fixed on the fixed head 28, and an assembly plate 30 is fixed above the corner slider 29, and a material shifting fork 31 is fixedly connected to the assembly plate 30. High-pressure gas is introduced into the cylinder body 26, causing the push rod 27 to move. Since the corner slider 29 is fixedly connected to the push rod 27, the displacement of the synchronous push rod 27 drives the corner slider 29 to move, that is, the assembly plate 30 also moves with the corner slider 29. At this time, when the corner slider 29 moves outward, the assembly plate 30 synchronously drives multiple material shifting forks 31 to move. In this way, under the action of the material shifting forks 31, the stator frame 17 on each clamping tool 12 can be quickly removed at the same time, without the need to remove them one by one manually. The equipment has a high degree of automation integration, which significantly improves the speed and efficiency of material removal, and is suitable for large-scale stator frame 17 winding production.

In this way, when the assembly plate 30 synchronously drives the multiple material shifting forks 31 to move, the material shifting fork 31 can be evenly stressed to shift out the stator frame 17 sleeved on the lower clamping block 14 and the upper clamping block 15, so that the stator frame 17 can fall off more smoothly without causing jamming. The material shifting fork 31 is stressed on both sides, and the stress during the material picking process is more uniform, which helps to reduce errors and unstable factors in the material picking process and improves the stability and accuracy of the operation.

When the stator frame 17 is sleeved on the lower clamping block 14 and the upper clamping block 15, the tail top mechanism is pressed against one side of the clamping tool 12, and the symmetrically installed limit blocks 22 wrap the lower clamping block 14 and the upper clamping block 15, and the limit blocks 22 and the front sections of the fitting block 21 are in contact and squeezed on the outside of the stator frame 17, so that an extrusion force can be generated, thereby stabilizing the stator frame 17 on the lower clamping block 14 and the upper clamping block 15, and it will not automatically detach from the lower clamping block 14 and the upper clamping block 15.
[0043] Further references Figure 8The clamping fixture 12 is provided with a hinge hole 19, and the tail end of the upper clamping block 15 is connected to the hinge hole 19 by a bolt hinge. The tail end of the lower clamping block 14 is provided with a circular joint 18, wherein the circular joint 18 is rotatably connected to the upper clamping block 15, and a corner opening 16 is provided on the lower clamping block 14 and the upper clamping block 15, and a propping block 23 is fixed in the middle of the fitting block 21. The propping block 23 will enter the corner opening 16 by being pushed against one side of the clamping fixture 12 by the tail pushing mechanism, wherein the propping block 23 and the corner opening 16 are both chamfered, and the chamfering treatment can remove burrs and sharp angles at the end of the workpiece, making the plug-in process smoother, reducing the resistance and friction during assembly, and thus improving the plug-in efficiency; the edge of the workpiece after chamfering treatment is smoother, which helps to reduce the deviation during assembly, improve the assembly accuracy, and ensure the stability and reliability of the plug-in part; the chamfering treatment can reduce the scratches or damage caused by sharp angles or burrs during the plug-in process, and protect the surface of the propping block 23 and the corner opening 16 The quality is improved and the service life of the components is extended.

When the stator frame 17 does not deviate or shake, the stator frame can be quickly clamped. At the same time, the setting of the tail top mechanism improves the winding accuracy during the winding process of the stator frame.

[0048] Step 1: sleeve the stator frame 17 between the lower clamping block 14 and the upper clamping block 15 .
[0049] Step 2: the tail top mechanism is displaced, and the opening block 23 is inserted into the corner opening 16 . The upper clamping block 15 rotates upward, and the lower clamping block 14 rotates downward, that is, the opening block 23 opens the lower clamping block 14 and the upper clamping block 15 .
[0050] Step three, winding the wire through a winding mechanism.
[0051] Step 4. After the winding is completed, the material shifting mechanism is operated, and high-pressure gas is introduced into the cylinder body 26 to cause the push rod 27 to move. At this time, when the corner slider 29 moves outward, the assembly plate 30 simultaneously drives multiple material shifting forks 31 to move. In this way, under the action of the material shifting fork 31, the stator frame 17 on each clamping tool 12 can be quickly removed at the same time. High-pressure gas is introduced into the cylinder body 26 again to reset the corner slider 29 and complete the material shifting action.
