Description

Technical Field

[0001] This application relates to the field of motor stator assembly, and more particularly to an automatic cold forming machine for slotted paper. Background Technology

[0002] Some modern motor stators are not integrally formed, but rather composed of several ring-shaped iron cores with insulating grooves on each core to isolate the coils on adjacent cores. In actual assembly, the cores are manually inserted into a fixture one by one, and then the assembled stator is placed in a heating device to heat and shape the insulating grooves. This process is time-consuming and inefficient. Summary of the Invention

[0003] To improve stator assembly efficiency, this application provides an automatic cold forming machine for slotted paper.

[0004] The automatic cold forming machine for slotted paper provided in this application adopts the following technical solution: An automatic cold forming machine for slotted paper includes a support worktable, a stator fixture, a fixture indexing and rotating device, a core support device, a core pushing device, and an elastic clamp. The stator fixture is used to position a fan-shaped annular core and is rotatably connected to the support worktable. The stator fixture includes a stator support base. The stator support base has several circumferentially evenly distributed fan-shaped core slots for the core to be inserted. The core slots of the stator support base are axially horizontally arranged. The fixture indexing and rotating device is used to drive the stator fixture to rotate intermittently at equal angles. The core support device is located on one side of the stator support base and close to the opening of the core slot. The core support device allows the core to slide horizontally. The core pushing device is used to push the core along the core support device into the corresponding core slot. The elastic clamp is used to hold the assembled annular stator.

[0005] By adopting the above technical solution, the iron core is placed on the iron core support device, and the iron core pushing device pushes the iron core into the corresponding iron core slot. Then, the tooling indexing and rotating device drives the stator tooling to rotate at an angle, so that the next iron core slot is facing the iron core pushing device. In this way, according to the above principle, the iron core enters the corresponding iron core slot. The stator tooling rotates at equal angles for one revolution at intervals, and all the iron core slots on the stator tooling are filled with iron cores, thus forming a circular stator. Then, the elastic clamp is put on the assembled stator, and finally the assembled stator and elastic clamp are taken out together. During this removal process, due to the action of the elastic clamp, all the iron cores are finally combined into a complete stator. In this process, there is no need to manually insert the iron core one by one, which effectively improves the stator assembly efficiency.

[0006] Optionally, the stator support base includes a cylindrical stator support outer column and a stator support inner column; the stator support outer column has a coaxially arranged cylindrical groove formed on its end face near the core support device; the stator support inner column is fixed to the bottom surface of the groove; the stator support inner column includes a cylindrical main support inner column coaxially arranged with the groove and a plurality of radially arranged isolation plates evenly distributed on the cylindrical surface of the main support inner column; the core slot is the space between the cylindrical surface of the groove, the cylindrical surface of the main support inner column and a pair of adjacent isolation plates.

[0007] By adopting the above technical solution, the isolation plate divides the annular groove between the main support inner column and the stator support outer column into a core slot for core insertion, which makes the core slot easy to process.

[0008] Optionally, the end of the isolation plate away from the stator support column has a chamfered edge on the side near the mounting groove.

[0009] By adopting the above technical solution, the opening of the iron core slot is formed into a flared shape, which facilitates the entry of the iron core into the iron core slot.

[0010] Optionally, the core support device includes a core support body; the core support body includes an upper core support seat; a rectangular groove is formed on the upper surface of the upper core support seat; the length direction of the groove is parallel to the axial direction of the core slot and the two ends of the groove are open; the groove allows the lower end of the core to slide.

[0011] By adopting the above technical solution, the lower end of the iron core is slidably set between a pair of moving slots, so that the movement direction of the iron core is accurate, which is conducive to the iron core entering the iron core slot.

[0012] Optionally, the core pushing device includes a pushing rod and a pushing drive mechanism for driving the pushing rod; a rectangular drive groove is formed in the middle of the bottom surface of the moving groove; the pushing rod is horizontally slidably disposed in the drive groove; the length direction of the drive groove is parallel to the axial direction of the core slot and both ends of the moving groove are open; a pushing block is fixed to one end of the pushing rod near the core slot; the pushing block is used to abut against the end of the core away from the core slot.

[0013] By adopting the above technical solution, the push drive mechanism drives the push rod to move, so that the push block drives the iron core to move into the iron core slot, which makes the structure simple.

[0014] Optionally, the core support body further includes a U-shaped upper baffle with the opening facing downwards; the upper baffle spans across and is fixed to the upper support seat of the core; a pair of lower insulating paper bending blocks are fixed on the upper support seat of the core; the pair of lower insulating paper bending blocks are distributed along the width direction of the upper support seat of the core and are located on the side of the upper baffle away from the core slot; the end of the lower insulating paper bending block away from the upper baffle is formed with a curved surface for folding the insulating paper upwards on the lower side of the core; the end of the upper baffle near the lower insulating paper bending block is formed with a curved surface for folding the insulating paper downwards on the upper side of the core.

[0015] By adopting the above technical solution, during the process of the iron core moving into the iron core slot, the curved surface on the lower insulating paper bending block first causes the lower insulating paper to be folded upwards, and then the curved surface of the upper baffle causes the upper insulating paper to be folded downwards. In this way, the edge folding of the insulating paper is completed during the movement of the iron core, eliminating the need for manual edge folding and greatly improving the assembly efficiency of the stator.

[0016] Optionally, it also includes a horizontal drive device; the core support device moves horizontally on the upper surface of the support worktable; the direction of movement of the core support device is parallel to the axis of the core slot; the horizontal drive device is used to drive the core support device away from or towards the stator support base.

[0017] By adopting the above technical solution, when the elastic clamp is installed, the horizontal drive device drives the iron core support device away from the stator support seat, which facilitates the installation of the elastic clamp and helps to improve the assembly efficiency of the stator.

[0018] Optionally, it also includes a stator discharge drive device; the stator tooling further includes a stator ejection mechanism; the stator ejection mechanism rotates synchronously with the stator support; the stator ejection mechanism includes an ejection moving seat and a plurality of cylindrical push rods formed on the end face of the ejection moving seat near the stator support; the push rods correspond one-to-one with the iron core slots and the push rods pass horizontally through the bottom of the iron core slots on the corresponding sides; the stator discharge drive device is used to drive the stator ejection mechanism to move horizontally.

[0019] By adopting the above technical solution, after the elastic clamp is set, the stator discharge drive device drives the stator ejection mechanism to move. All the push rods of the stator ejection mechanism push all the iron cores to move outward together, that is, the assembled stator and the elastic clamp move outward together. This will not damage the assembled stator, and at the same time, the stator is convenient to discharge.

[0020] Optionally, the stator discharge drive device includes a stator discharge drive mechanism and a stator discharge push plate; the stator discharge push plate is rotatably connected to the ejection moving seat; the stator discharge drive mechanism is used to drive the stator discharge push plate and the ejection moving seat to move in a direction parallel to the axis of the push rod.

[0021] By adopting the above technical solution, the stator discharge pusher plate does not affect the rotation of the ejection moving seat during assembly; after assembly, the stator discharge drive mechanism drives the stator discharge pusher plate and the ejection moving seat to move horizontally in sync, thereby driving the push rod to eject all the iron cores, which effectively ensures the smooth operation of the equipment.

[0022] Optionally, the ejector movable seat is cylindrical and a coaxially arranged annular groove-shaped connecting slot is formed on the cylindrical surface of the ejector movable seat; a semi-cylindrical groove-shaped connecting groove is formed at one end of the stator discharge push plate near the ejector movable seat; the connecting groove is axially through and its radius is equal to the inner diameter of the connecting slot; the stator discharge push plate is inserted into the connecting slot and the connecting slot is coaxially arranged with the connecting groove.

[0023] By adopting the above technical solution, the stator discharge pusher plate and ejection moving seat have a simple structure, are easy to connect, and are easy to disassemble. In summary, the beneficial effects of this application are as follows: 1. No need for manual insertion of iron cores one by one, effectively improving stator assembly efficiency.

[0024] 2. No manual folding is required, which greatly improves the assembly efficiency of the stator. Attached Figure Description

Figure 4 The stator moves into the lowest core slot, then the indexing servo motor rotates the stator fixture 40 degrees, positioning the next empty core slot at the bottom.
