Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a motor core pressing and alignment device. Background Technology

[0002] The stacking and welding of sector-shaped stator cores into motor cores requires vertical pressing. In order to ensure uniform welding and prevent welding deformation, an automatic welding machine is required. Since the inner diameter of the sector-shaped stator core must be tightly fitted with the outer circle of the tooling body during pressing, the core must be automatically pressed out of the tooling body on the stacking machine before welding and demolding.

[0003] Chinese patent document CN215845288U discloses a novel motor core pressing device, including a base plate with support legs connected to all four sides of the bottom. A buffer groove is connected to the center of the top of the base plate, and a lower mold is located within the buffer groove. A buffer mechanism is connected between the lower mold and the buffer groove. A positioning rod is connected to the outer side of the top of the lower mold, and a positioning block is connected to the center of the top of the lower mold. Support plates are symmetrically connected to the top of the base plate, and telescopic rods are connected to the inner sides of the support plates facing the lower mold. Clamping blocks are connected to the free ends of the telescopic rods. A top plate is connected between the tops of the symmetrical support plates, and a hydraulic cylinder is connected to the center of the top plate. Multiple connecting rods are connected to the telescopic ends of the hydraulic cylinder below the top plate, and an upper mold is connected to the bottom of the connecting rods. The advantages of this utility model compared with the prior art are: it provides a novel motor core pressing device with good fixing effect for stacked plates, prevents displacement during the stamping process, and facilitates demolding.

[0004] The existing technology has the following problems:

[0005] The device uses a fixed positioning rod to fix the motor core directly. However, this method is difficult to adapt to motors of different sizes and specifications. In addition, the fixed positioning rod needs to be aligned with the position of the positioning rod when installing the motor core, which does not allow for error and makes the placement operation inconvenient. Utility Model Content

[0006] This invention provides a motor core pressing and alignment device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5 As shown, a motor core pressing and alignment device includes a base plate 1. A platform 2 is fixedly connected to the upper side of the base plate 1 near the left and right sides. A buffer mechanism 3 is movably installed on the mounting bracket in the middle of the lower side of the base plate 1. A fixing mechanism 4 is movably installed on the upper side of the buffer mechanism 3. Two clamping mechanisms 5 are fixedly connected to the upper side of the base plate 1 near the left and right sides. A pressing mechanism 6 is movably installed in the middle of the lower side of the upper wall of the platform 2.

[0027] The fixing mechanism 4 includes a base 41, a positioning block 42 is fixedly connected to the upper middle part of the base 41, a number of ring-shaped limiting components 43 are slidably connected to the upper side of the base 41, a number of evenly distributed fixing holes 44 are opened on the upper side of the base 41, the limiting component 43 includes a fixing seat 431, the lower side of the fixing seat 431 is slidably connected to the upper side of the base 41, and two symmetrically distributed screws 432 are threaded to both sides of the fixing seat 431, the outer side of the screws 432 is movably sleeved on the inner side of the fixing hole 44.

[0028] It should be noted that the buffer mechanism 3, the pressing mechanism 6 and the positioning block 42 have the same structural design as the components with the same function in the reference case. The position of the fixing seat 431 is adjusted by inserting the screw 432 into the fixing hole 44 at different positions.

[0029] like Figure 4 As shown, a first electric push rod 433 is fixedly connected to the upper middle part of the fixed base 431, and a vertical rod 434 is fixedly connected to the side of the first electric push rod 433 near the positioning block 42.

[0030] It should be noted that the first electric push rod 433 can drive the vertical rod 434 to move, which is used to supplement the position between two adjacent fixing holes 44. At the same time, it ensures that when installing the motor core, the fixed position of the fixing seat 431 will not cause the motor core to be installed without error, thus facilitating installation.

[0031] like Figure 3 , Figure 4 As shown, the upper side of screw 432 is inclined toward positioning block 42.

[0032] It should be noted that the state of screw 432 reduces the impact of the lateral pressure exerted by the motor core on the vertical rod 434 on screw 432, making the position of the fixing seat 431 more stable.

[0033] like Figure 4 As shown, a rubber pad is fixedly connected to the lower side of the fixing base 431.

[0034] It should be noted that the rubber pad is used to prevent the screw 432 from being over-tightened, which could lead to stripping of the threads or deformation of the parts due to compression.

[0035] like Figure 1 , Figure 5As shown, the clamping mechanism 5 includes a base frame 51. Two threaded seats 52 distributed front and rear are rotatably connected to the upper side of the base frame 51. A motor 53 is fixedly connected to the middle of the upper side of the base frame 51. Gears 54 are fixedly connected to the outer sides of the two threaded seats 52 and the output end of the motor 53. Screws 56 are threadedly connected to the inner sides of the two threaded seats 52. A movable plate 55 is fixedly connected to the side of the screw 56 near the top pressing mechanism 6. A clamping block 57 is fixedly connected to the side of the movable plate 55 near the top pressing mechanism 6.

[0036] It should be noted that the gear 54 on the motor 53 meshes with the gear 54 on the threaded seat 52, so that when the motor 53 drives the gear 54 to rotate, the threaded seat 52 rotates, which in turn causes the screw 56 to drive the moving plate 55 to move left and right, so that the clamping block 57 clamps the motor core.

[0037] like Figure 1 , Figure 5 As shown, two slide rails 58 are slidably connected to the lower side of the base frame 51 near the front and rear sides. The lower side of the slide rails 58 is fixedly connected to the upper side of the substrate 1 near the left and right sides. Two second electric push rods 59 are fixedly connected to the side of the base frame 51 away from the top pressing mechanism 6. The side of the second electric push rods 59 away from the top pressing mechanism 6 is fixedly connected to the upper side of the substrate 1 near the left and right sides.

[0038] It should be noted that the second electric push rod 59 is used to move the base frame 51 left and right. Due to the presence of the slide rail 58, the base frame 51 is more stable when moving.

[0039] like Figure 1 As shown, four sets of rectangular scale lines are provided on the upper side of the substrate 1 near the left and right sides.

[0040] It should be noted that the scale lines are used to indicate the range of movement of the components, and the scale lines on the front and rear sides can also be used to indicate whether the connection between the components is loose, so that the moving plate 55 or the clamping block 57 will be tilted.

[0041] The working principle of this utility model is as follows: First, by inserting screws 432 into fixing holes 44 at different positions, the position of the fixing seat 431 is adjusted. The first electric push rod 433 can drive the vertical rod 434 to move, which is used to supplement the position between two adjacent fixing holes 44. At the same time, it ensures that when installing the motor core, the fixed position of the fixing seat 431 will not cause the motor core to be placed without error, making installation convenient. The state of the screws 432 reduces the impact of the lateral pressure of the motor core on the vertical rod 434 on the screws 432, making the position of the fixing seat 431 more stable. By inserting screws 432 into fixing holes 44 at different positions, the position of the vertical rod 434 can be adjusted significantly. Then, the first electric push rod 433 can be used to adjust the position of the vertical rod 434 slightly. The adjustment is convenient, the operation is simple, and it is convenient for the installation of the motor core. Meanwhile, the first electric push rod 433 allows for error tolerance during the placement of the iron core. Finally, the gear 54 on the motor 53 meshes with the gear 54 on the threaded seat 52, causing the threaded seat 52 to rotate as the motor 53 drives the gear 54 to rotate. This causes the screw 56 to move the moving plate 55 left and right, allowing the clamping block 57 to clamp the motor iron core. The second electric push rod 59 is used to move the base frame 51 left and right. Due to the presence of the slide rail 58, the base frame 51 moves more stably. The second electric push rod 59 drives the clamping block 57 to move significantly, while the motor 53 drives the clamping block 57 to move slightly, thus clamping the motor iron core. This avoids the problem of asynchronous adjustment on both sides caused by manual rotation, and also avoids the problem of unstable operation of components caused by manual adjustment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
