Description

Technical Field

[0001] This invention relates to the field of mold-feeding device technology, and more specifically to an automatic stator core mold-feeding device. Background Technology

[0002] The stator core is an important component of the magnetic circuit of a servo motor. Together with the rotor core and the air gap between the stator and rotor, it forms the complete magnetic circuit of the servo motor. In an asynchronous servo motor, the magnetic flux in the stator core is alternating, which results in core losses. Core losses include two parts: hysteresis losses and eddy current losses.

[0003] The shortcomings of existing technology: The stator core is made by stacking multiple silicon steel sheets. In order to ensure the production quality of the stator core, after the stator core is produced, it needs to be placed in a straightening mold to straighten the verticality of the stator core. Since the stator core has a certain weight after production, and the center of the stator core needs to be straightened when placed in the straightening mold, manual operation is time-consuming and labor-intensive. Therefore, we propose an automatic stator core mold feeding device. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic stator core mold feeding device to solve the problems existing in the background art.

[0005] This invention provides the following technical solution: an automatic stator core mold feeding device, comprising a worktable and a straightening mold assembly disposed on the worktable, a transport assembly disposed at the lower end of the worktable, the transport assembly comprising an input mechanism, an output mechanism and a lifting mechanism, a mold feeding assembly disposed at the upper end of the worktable, the mold feeding assembly comprising a translation mechanism and a positioning mechanism, the translation mechanism comprising a guide frame, a connecting seat and a transfer cylinder, a pair of guide frames disposed on the worktable, each pair of guide frames having a guide groove on its surface, the connecting seat being slidably connected in the guide groove, and the transfer cylinder being connected between the connecting seats; The positioning mechanism includes guide holes, connecting shafts, a first roller, a second roller, and a ramp. Multiple guide holes are formed on the circumferential surface of the transfer cylinder. The connecting shafts are all slidably connected within the guide holes. Rotating seats are fixedly connected to both ends of the connecting shafts. A first roller located inside the transfer cylinder and a second roller located outside the transfer cylinder are rotatably connected within the rotating seats. A first spring is fixedly connected between the rotating seats located outside the transfer cylinder and the transfer cylinder. The ramp is located inside the guide frame, and the second roller is rotatably connected to the ramp. Preferably, each of the guide frames is provided with a rotating frame, and each rotating frame is rotatably connected with a threaded rod that is threaded to the connecting seat. The threaded rods are connected to each other by a sprocket set, and one of the threaded rods is connected to the output end of a servo motor located at the rear end of the guide frame.

[0006] Preferably, both the input mechanism and the output mechanism include a conveyor guide and a conveyor belt disposed within the conveyor guide. The conveyor belt in the input mechanism rotates intermittently, while the conveyor belt in the output mechanism rotates continuously.

[0007] Preferably, the conveyor belts in both the input and output mechanisms are used to transport the stator core body, which is loaded and unloaded via a lifting mechanism.

[0008] Preferably, the lifting mechanism includes a connecting plate, a connecting rod, a lifting block, and an inlet / outlet hole. The connecting rod is slidably connected inside the conveying guide frame. The lifting block is disposed at the upper end of the connecting rod. The connecting plate is disposed at the lower end of the connecting rod. The upper end of the connecting plate is connected to the cylinder output end fixedly connected to the lower end of the worktable. The inlet / outlet hole is opened on the upper surface of the worktable.

[0009] Preferably, the lowest position of the lifting block is lower than the surface of the conveyor belt, and the highest position of the lifting block is flush with the worktable.

[0010] Preferably, the straightening mold assembly includes a support frame, a hydraulic cylinder, an extrusion module, and a straightening module. The support frame is disposed on the upper end of the worktable, the hydraulic cylinder is disposed on the upper end of the support frame, and the output end of the hydraulic cylinder is slidably connected to the support frame. The extrusion module is disposed on the lower end of the hydraulic cylinder output end, the straightening module is slidably connected inside the extrusion module, a second spring is fixedly connected between the upper end of the straightening module and the inner side of the extrusion module, and the straightening module is slidably connected to the stator core body.

[0011] Preferably, the transfer cylinder has a sliding groove, the sliding groove is slidably connected to a connecting block, the connecting blocks are fixedly connected to each other, and a third spring is provided in the sliding groove and fixedly connected to the lower end of the connecting block.

[0012] The technical effects and advantages of this invention are as follows: 1. This invention controls the transfer cylinder to push the stator core body to the right, so that it enters the straightening mold assembly. During the movement of the transfer frame to the right, the slope changes, and with the action of the second roller and the connecting shaft, the first roller moves inward at the same time. Since the arc formed between the first rollers after contraction matches the arc of the outer diameter of the stator core body, the position of the stator core body can be automatically adjusted when it enters the straightening mold assembly, thus completing the position correction of the stator core body and placing it at the center of the straightening mold assembly. Subsequently, the verticality correction of the stator core body can be completed by the straightening mold assembly.

[0013] 2. This invention uses a cylinder to operate, which causes the left-side lifting block to move the stator core body upward, allowing it to pass through the inlet / outlet hole and move to a position flush with the worktable. After the stator core body is corrected, it moves to the right-side lifting block. At this time, the cylinder retracts and resets, and the right-side lifting block then causes the stator core body to pass through the inlet / outlet hole and fall into the output mechanism. The output mechanism then transports and unloads the stator core body. Subsequently, the input mechanism transports subsequent stator core bodies to the left-side lifting block. Through the continuous operation of the lifting mechanism, the automatic loading and unloading of the stator core body is completed. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automatic stator core mold feeding device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1-9 As shown, in one embodiment, an automatic stator core mold feeding device is proposed, including a workbench 1 and a straightening mold assembly 2 disposed on the workbench 1. A transport assembly 3 is disposed at the lower end of the workbench 1. The transport assembly 3 includes an input mechanism 31, an output mechanism 32 and a lifting mechanism 33. A mold feeding assembly 4 is disposed at the upper end of the workbench 1. The mold feeding assembly 4 includes a translation mechanism 41 and a positioning mechanism 42. The translation mechanism 41 includes a guide frame 411, a connecting seat 413 and a transfer cylinder 414. A pair of guide frames 411 are disposed on the workbench 1. A guide groove 412 is opened on the surface of each pair of guide frames 411. The connecting seat 413 is slidably connected in the guide groove 412. The transfer cylinder 414 is connected between the connecting seats 413. The positioning mechanism 42 includes a guide hole 421, a connecting shaft 422, a first roller 424, a second roller 425, and a ramp 427. Multiple guide holes 421 are formed on the circumferential surface of the transfer cylinder 414. The connecting shaft 422 is slidably connected to the guide holes 421. Rotating seats 423 are fixedly connected to both ends of the connecting shaft 422. The first roller 424 located inside the transfer cylinder 414 and the second roller 425 located outside the transfer cylinder 414 are rotatably connected inside the rotating seat 423. A first spring 426 is fixedly connected between the rotating seat 423 located outside the transfer cylinder 414 and the transfer cylinder 414. The ramp 427 is set inside the guide frame 411. The second roller 425 is rotatably connected to the ramp 427.

[0026] In practical application, the stator core body 7 is placed in the input mechanism 31 and conveyed to the worktable 1 by the conveyor belt 302. Then, the stator core body 7 is lifted onto the worktable 1 by the lifting mechanism, where it is located in the transfer cylinder 414. The connecting seat 413 moves to the right within the guide frame 411, pushing the stator core body 7 to the right and allowing it to enter the straightening mold assembly 2. During the rightward movement of the transfer cylinder, the second roller 425 pushes the connecting shaft 422 inward due to the changing arc of the ramp 427. Simultaneously, the connecting rod shaft pushes the first roller 424 inward, causing the first roller 424 to move inward. The arc formed by the contraction of the first roller 424 and the stator core... With the outer diameter arc dimension of the stator core body 7 matched, its position can be automatically adjusted when the stator core body 7 enters the straightening mold assembly 2, completing the position correction of the stator core body 7 so that the stator core body 7 is located in the center position of the straightening mold assembly 2. Then, the verticality correction of the stator core body 7 can be completed by the straightening mold assembly 2. After the correction is completed, the stator core body 7 is controlled to move to the right again. With the change of the ramp 427, the rollers will spread out in all directions under the action of the first spring 426 until the stator core body 7 moves to the top of the output mechanism 32. Then, the lifting mechanism 33 operates to move the stator core body 7 to the lower output mechanism 32 to complete the unloading. Then, the transfer rack resets and moves to the left to the top of the input mechanism 31, ready for the next stator core body 7 to be put into the mold.

[0027] like Figure 5 and 6 As shown, in a preferred embodiment of the present invention, the guide frame 411 is provided with a rotating frame 5 on its surface. Each rotating frame 5 is rotatably connected with a threaded rod 501 that is threaded to the connecting seat 413. The threaded rods 501 are connected to each other through a sprocket set 502. One of the threaded rods 501 is connected to the output end of the servo motor 503 located at the rear end of the guide frame 411.

[0028] In practical applications, by controlling the operation of the servo motor 503, the servo motor 503 will drive the threaded rod 501 to rotate. Then, under the action of the sprocket group 502, both threaded rods 501 can be driven to rotate simultaneously, thereby achieving the effect of driving the connecting seat 413 to slide within the guide frame 411.

[0029] like Figure 2-4 As shown, in another preferred embodiment of the present invention, both the input mechanism 31 and the output mechanism 32 include a conveyor guide 301 and a conveyor belt 302 disposed within the conveyor guide 301. The conveyor belt 302 in the input mechanism 31 rotates intermittently, while the conveyor belt 302 in the output mechanism 32 rotates continuously.

[0030] In practical application, the stator core body 7 is conveyed forward by the input mechanism 31 when it is placed on the conveyor belt 302. The conveying stops when one stator core body 7 is conveyed to the lifting mechanism 33. When the lifting mechanism 33 is lowered and reset, it starts to convey the stator core body 7 to the lifting mechanism 33 again. The output mechanism 32 moves the straightened stator core body 7 down and it falls onto the conveyor belt 302. The straightened stator core body 7 can be output and unloaded by the rotation of the conveyor belt 302.

[0031] like Figure 1-4 As shown, in another preferred embodiment of the present invention, the conveyor belts 302 in the input mechanism 31 and the output mechanism 32 are both used to transport the stator core body 7, and the stator core body 7 is loaded and unloaded by the lifting mechanism 33.

[0032] In practical applications, when the stator core body 7 is being prepared for input correction and when it is being output after correction, it needs to be input into the transfer cylinder 414 and output from the transfer cylinder 414 through the lifting mechanism 33.

[0033] like Figure 2-4 As shown, in another preferred embodiment of the present invention, the lifting mechanism 33 includes a connecting plate 333, a connecting rod 331, a lifting block 332, and an inlet / outlet hole 335. The connecting rod 331 is slidably connected in the conveying guide 301. The lifting block 332 is disposed at the upper end of the connecting rod 331. The connecting plate 333 is disposed at the lower end of the connecting rod 331. The upper end of the connecting plate 333 is connected to the output end of the cylinder 334 fixedly connected to the lower end of the worktable 1. The inlet / outlet hole 335 is opened on the upper surface of the worktable 1.

[0034] In practical application, the cylinder 334 operates, which in turn drives the lifting block 332 upward via the connecting plate 333 and the connecting rod 331. The left lifting block 332 then drives the stator core body 7 upward, allowing it to pass through the inlet / outlet hole 335 and move to a position flush with the worktable 1. After the stator core body 7 is corrected, it moves to the right lifting block 332. At this time, the cylinder 334 retracts and resets, and the right lifting block 332 drives the stator core body 7 to pass through the inlet / outlet hole 335 and fall into the output mechanism 32. The output mechanism 32 then conveys and unloads the stator core body 7. Subsequently, the input mechanism 31 continues to convey subsequent stator core bodies 7 to the left lifting block 332. Through the continuous operation of the lifting mechanism, the loading and unloading of the stator core body 7 is completed.

[0035] like Figure 3 As shown, in another preferred embodiment of the present invention, the lowest position of the lifting block 332 is lower than the surface of the conveyor belt 302, and the highest position of the lifting block 332 is flush with the worktable 1.

[0036] In practical application, since the position of the lifting block 332 is lower than that of the conveyor belt 302, when the lifting block 332 rises and falls, the stator core body 7 on the conveyor belt 302 can be lifted and placed on the conveyor belt 302. After the lifting block 332 is lifted, it is flush with the worktable 1. Then, under the action of the mold feeding mechanism, the position of the stator core body 7 can be moved.

[0037] like Figure 9 As shown, in another preferred embodiment of the present invention, the straightening module assembly 2 includes a support frame 201, a hydraulic cylinder 202, an extrusion module 203, and a straightening module 204. The support frame 201 is disposed on the upper end of the workbench 1, the hydraulic cylinder 202 is disposed on the upper end of the support frame 201, and the output end of the hydraulic cylinder 202 is slidably connected to the support frame 201. The extrusion module 203 is disposed on the lower end of the output end of the hydraulic cylinder 202, and the straightening module 204 is slidably connected inside the extrusion module 203. A second spring 205 is fixedly connected between the upper end of the straightening module 204 and the inner side of the extrusion module 203. The straightening module 204 is slidably connected to the stator core body 7.

[0038] In practical application, when the stator core body 7 moves to the center position of the straightening mold mechanism, the hydraulic cylinder 202 operates, which drives the extrusion module 203 and the straightening module 204 to move downward. First, the straightening module 204 passes through the center of the stator core body 7 to correct the verticality of the stator core body 7. Then, the extrusion module 203 extrudes the stator core body 7 to compact it. Finally, the straightening mold assembly 2 is reset to complete the vertical straightening effect of the stator core body 7.

[0039] like Figure 8 As shown, in another preferred embodiment of the present invention, a sliding groove 6 is provided in the transfer cylinder 414, a connecting block 601 is slidably connected to the sliding groove 6, a limit block 602 is fixedly connected between the connecting blocks 601, and a third spring 603 is provided in the sliding groove 6 and fixedly connected to the lower end of the connecting block 601.

[0040] In practical application, when the extrusion module 203 descends to a lower position, it first contacts the limiting block 602 and then presses down on the limiting block 602. The limiting block 602 presses down on the stator core body 7. At the same time, the limiting block 602 can restrict the upper position of the stator core body 7. When the correction module 204 resets, it can prevent the correction module 204 from being too close to the stator core body 7 when it is vertically correcting it, which would cause the correction module 204 to lift the stator core body 7 upward when it rises.

[0041] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
