Description

Technical Field

[0001] This utility model relates to the field of stator processing technology, specifically to a stator clamping mechanism for motor stator processing. Background Technology

[0002] An electric motor is a device that uses stator windings to generate a rotating magnetic field and act on the rotor to form a magnetoelectric torque. The stator is composed of a stator core, stator windings, and a frame. The stator core is an important component of the motor, which directly affects the quality of the motor. The stator core is made by stacking stamped loose pieces, pressing them together with a press, and then welding them together.

[0003] The applicant previously applied for a stator clamping mechanism for motor stator processing, with publication number "CN219779957U". The mechanism includes a base plate, a first rotating disk fixedly connected to the upper surface of the base plate, a first gear rotatably connected to the upper surface of the first rotating disk, and a clamping base fixedly connected to the upper surface of the first gear. The clamping base has a second sliding groove inside, and a second slider slidably connected to the inner wall of the second sliding groove. A fixing plate is fixedly connected to the upper surface of the second slider. When iron core pieces are placed on the clamping base, the second slider moves the fixing plate, thereby fixing the iron core pieces from the inner wall, ensuring that the axis of the iron core pieces remains consistent, and thus preventing displacement during clamping.

[0004] However, during use, it was found that because the fixing plate is located inside the inner wall of the iron core pieces, after the iron core pieces are pressed and welded, the heat generated on the outer wall of the iron core pieces is too great, and the workers cannot quickly remove the iron core pieces from the outside of the fixing plate. They need to wait for them to cool down before they can be removed, and they need to be removed manually, which reduces automation and thus reduces work efficiency. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a stator clamping mechanism for motor stator processing that improves automation and increases work efficiency, in order to address the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stator clamping mechanism for motor stator processing, comprising a machine base, a first rotating disk rotatably mounted on the machine base, a clamping assembly vertically mounted above the first rotating disk on the machine base, and a welding device mounted on one side of the machine base on the first rotating disk. The first rotating disk has at least four sets of first sliding grooves on its upper surface, each first sliding groove having a first electric push rod at its end furthest from the center point of the first rotating disk. The output end of the first electric push rod is connected to an electric cylinder, and the output end of the electric cylinder is connected to a fixed plate. The first rotating disk has several connecting columns between the first sliding grooves, each connecting column having a worktable at its upper end. The worktable has second sliding grooves corresponding to the first sliding grooves, and each second sliding groove is interconnected. The electric cylinder can drive the fixed plate to move vertically, thereby passing through the second sliding grooves or being positioned between the worktable and the first rotating disk. The machine base has a material-grabbing device on the other side of the first rotating disk capable of gripping loose iron core sheets.

[0007] The above technical solution, compared with the existing technology which has a low degree of automation and requires manual material handling, firstly places the iron core pieces on the worktable. Then, by activating the first electric push rod, the fixing plate moves along the first and second sliding grooves to a suitable position. Next, the electric cylinder drives the fixing plate upwards, allowing it to be positioned on the inner wall of the iron core pieces, thus fixing them and ensuring their axis remains aligned, preventing misalignment during clamping. Then, the iron core pieces are welded using a welding device. Finally, after welding, the electric cylinder lowers the fixing plate, removing the need to fix the iron core pieces. At this point, the material handling device can grab the welded iron core pieces and move them to the next process, thus improving work efficiency.

[0008] A further feature of this invention is that the material handling device includes a mounting frame, a second rotating disk is rotatably mounted on the upper surface of the mounting frame, a second motor is mounted at the bottom of the mounting frame and is linked to the second rotating disk, a second electric push rod is connected to the second rotating disk, a mounting plate is connected to the output end of the second electric push rod, and a clamping cylinder is fixedly connected to the other side of the mounting plate away from the second electric push rod.

[0009] The above technical solution is adopted as follows: the second motor drives the second rotating disk, so that when it is necessary to unload the iron core pieces, the rotation of the second rotating disk drives the output end of the clamping cylinder to face the worktable, and then the second electric push rod is activated to push the clamping cylinder closer to the iron core pieces. Finally, the clamping cylinder is activated to grab the iron core pieces, and then the second motor is activated again to drive the second rotating disk to rotate, so that the clamping cylinder carries the iron core pieces to the next process.

[0010] A further feature of this invention is that the outer wall of the electric cylinder is provided with a first mounting cover and a second mounting cover that are symmetrical to each other. The first and second mounting covers are provided with corresponding first mounting blocks on both sides. The outer wall of the first mounting cover is provided with a second mounting block that is connected to the output end of the first electric push rod between the first mounting blocks.

[0011] The above technical solution facilitates the assembly of the first electric push rod and the electric cylinder by setting up the first mounting cover and the second mounting cover. The structure is simple and easy to disassemble and install.

[0012] A further feature of this invention is that the bottom of the machine base is equipped with a first motor that is linked to the first rotating disk.

[0013] The above technical solution is adopted: by setting the first motor, the first rotating disk can be driven to rotate, thereby driving the worktable to rotate, so that multi-point welding can be achieved when the welding device is welding.

[0014] A further feature of this invention is that the welding device includes a slide rail, a slider is slidably mounted on the slide rail, a third electric push rod is fixedly connected to the outer wall of the slider, and a welding torch is connected to the output end of the third electric push rod.

[0015] The above technical solution is adopted: by setting the slide rail and the slider, the third electric push rod and the welding torch can be raised and lowered by the slider on the slide rail. At the same time, the third electric push rod can push the welding torch closer to the iron core sheet, so as to weld it.

[0016] A further feature of this invention is that the clamping assembly includes a support column disposed on the upper surface of the machine platform, a connecting block is fixedly connected to the outer wall of the support column, a hydraulic cylinder is disposed on the side of the connecting block away from the support column, a third rotating disk is rotatably connected to the output end of the hydraulic cylinder, a connecting plate is connected to the lower surface of the third rotating disk, and a clamping ring is disposed at the bottom of the connecting plate.

[0017] The above technical solution is adopted: the third rotating disk, connecting plate and clamping ring are pushed downward by the hydraulic cylinder, thereby achieving the effect of clamping the loose iron core pieces.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

At least four sets of first sliding grooves 21 are formed on the upper surface of the first rotating disk 2, and a first electric push rod 22 is mounted on the end of each first sliding groove 21 away from the center point of the first rotating disk 2. The output end of the first electric push rod 22 is connected to an electric motor. The output end of the electric cylinder 23 is connected to the fixed plate 24; the first rotating disk 2 is provided with several connecting columns 25 between the first slide grooves 21, and the upper end of the connecting column 25 is provided with a worktable 26. The worktable 26 is provided with a second slide groove 261 corresponding to the first slide groove 21, and each second slide groove 261 is interconnected. The electric cylinder 23 can drive the fixed plate 24 to move up and down, thereby passing through the second slide groove 261 or being located between the worktable 26 and the first rotating disk 2. The machine base 1 is provided with a material picking device 5 on the other side of the first rotating disk 2, which can pick up the iron core pieces.

[0027] like Figure 3The material handling device 5 shown includes a mounting frame 51. A second rotating disk 52 is rotatably mounted on the upper surface of the mounting frame 51. A second motor 53, which is linked to the second rotating disk 52, is located at the bottom of the mounting frame 51. A second electric push rod 54 is connected to the second rotating disk 52. A mounting plate 56 is connected to the output end of the second electric push rod 54. A clamping cylinder 55 is fixedly connected to the other side of the mounting plate 56 away from the second electric push rod 54.

[0028] like Figure 4 The outer wall of the electric cylinder 23 shown is provided with a first mounting cover 231 and a second mounting cover 232 that are symmetrical to each other. The first and second mounting covers are provided with corresponding first mounting blocks 233 on both sides. The outer wall of the first mounting cover 231 is provided with a second mounting block 231a that is connected to the output end of the first electric push rod 22 between the first mounting blocks 233.

[0029] like Figure 5 The welding device 4 shown includes a slide rail 41, a slider 42 is slidably mounted on the slide rail 41, a third electric push rod 43 is fixedly connected to the outer wall of the slider 42, and a welding gun 44 is connected to the output end of the third electric push rod 43.

[0031] Compared to existing technologies with low automation levels and the need for manual material handling, this invention, during use, first places the iron core sheets on the workbench 26. Then, by activating the first electric push rod 22, the fixing plate 24 is moved along the first and second sliding grooves 261 to a suitable position. Next, the electric cylinder 23 drives the fixing plate 24 upward, ensuring it is positioned within the inner wall of the iron core sheets, thus fixing them and ensuring their axis remains aligned to prevent misalignment during clamping. The iron core sheets are then welded together using the welding device 4. Finally, the welding process is completed. After completion, the electric cylinder 23 drives the fixing plate 24 to descend, so that the iron core pieces are no longer fixed. At this time, the output end of the clamping cylinder 55 can be driven to the worktable 26 by the rotation of the second rotating disk 52. Then, the second electric push rod 54 is activated to push the clamping cylinder 55 closer to the iron core pieces. Finally, the clamping cylinder 55 is activated to grab the iron core pieces. Then, the second motor 53 is activated again to drive the second rotating disk 52 to rotate, so that the clamping cylinder 55 can transport the iron core pieces to the next process, thereby improving work efficiency.
