Description

Technical Field

[0001] This utility model relates to the field of silicon steel sheet technology, specifically to a silicon steel sheet stamping and feeding device for motors. Background Technology

[0002] Silicon steel sheets for motors are part of the magnetic circuit system of an electric motor. They provide a path for the magnetic flux generated by the coils. Electrical silicon steel sheets are commonly known as silicon steel sheets or silicon steel plates. It is a low-carbon silicon-iron soft magnetic alloy made from cold-rolled silicon steel sheets. It possesses excellent magnetic and electrical properties and is widely used in power equipment such as motors, transformers, and generators. During the stamping process of silicon steel sheets, the unstamped material needs to be transported from the feeding point to the stamping machine, where it is stamped. After stamping, the stamped silicon steel sheets are unloaded, and then the process of feeding material onto the stamping machine continues.

[0003] Currently, for convenient transportation of silicon steel sheets for motors, an adsorption mechanism is generally used to hold the sheets in place. However, this adsorption mechanism needs to be adapted to the working height of the stamping machine and the material handling height of the feeding platform. Therefore, multiple drive devices and structures are required to drive the adsorption mechanism to move up and down and horizontally. This not only makes the transportation of silicon steel sheets for motors troublesome, but also increases the transportation cost and energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a stamping and feeding device for silicon steel sheets for motors, so as to solve the problem of cumbersome feeding of silicon steel sheets for motors in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor silicon steel sheet stamping and feeding device, comprising a base plate, a transport frame slidably connected to the upper part of the base plate, an mounting plate fixedly connected to one side of the transport frame, and two lifting plates slidably connected thereto. Vertical rods distributed at equal intervals are fixedly connected between the two lifting plates. A through hole is provided at the corresponding position of the mounting plate relative to the vertical rod. The vertical rod is slidably connected in the cavity of the through hole. A first spring is slidably sleeved on the outside of the vertical rod. The first spring is located between the topmost lifting plate and the mounting plate. An mounting frame is installed on the upper part of the base plate. An inclined pressure plate that contacts the topmost lifting plate is installed on one side of the mounting frame. An adsorption mechanism is provided at the bottom of the bottommost lifting plate.

[0006] Preferably, a feeding platform is provided above the base plate, and two fixing plates are fixedly connected to the upper part of the feeding platform and the base plate. Each fixing plate has a sliding groove on one side. Crossing mechanisms are provided on both sides of the feeding platform. Each of the two sets of crossing mechanisms includes two intersecting and mutually rotating inclined rods. The two ends of the inclined rods are slidably connected to the two corresponding upper and lower sliding grooves respectively.

[0007] Preferably, a movable rod is rotatably connected between the bottom ends of the two sets of inclined rods. A threaded hole is provided on one side of the movable rod. A bidirectional screw is rotatably connected to the upper part of the base plate. Both movable rods are threaded onto the outside of the bidirectional screw through their respective threaded holes. Two external threads are provided on the outside of the bidirectional screw in a mirror-symmetrical arrangement. The two movable rods are respectively threaded onto the two external threads.

[0008] Preferably, the upper part of the base plate is rotatably connected to a first worm wheel and a first worm, which are meshed with each other. One side of the first worm wheel is fixedly connected to one end of a bidirectional screw, and a gear is fixedly connected to the movable end of the first worm.

[0009] Preferably, a rack is provided on one side of the transport frame, and a linear array of meshing blocks is rotatably connected to one side of the rack.

A stop block is fixedly connected to the rack at a corresponding position relative to each meshing block, and the stop block is located on one side of the meshing block.

[0010] Preferably, a second threaded rod is rotatably connected to one side of the transport frame, and the rack rod is threaded onto the outside of the second threaded rod, and the rack rod is slidably connected to one side of the transport frame.

[0011] Preferably, a third threaded rod is rotatably connected to the upper part of the base plate, and a through threaded groove is provided on one side of the transport frame. The transport frame is threaded onto the outside of the third threaded rod through the threaded groove. A servo motor is installed on the upper part of the base plate. The servo motor is electrically connected to a power supply. The servo motor used in this application is a purchased component, selected according to power and size requirements.

This application uses rack and pinion and gear and other related structures to ensure that the material feeding platform is raised a certain distance each time the silicon steel sheet is transported by the transport frame. This ensures that the material picking height is the same each time, and avoids the material picking height being reduced due to the continuous removal of stacked silicon steel sheets. This can effectively improve the applicability of the motor silicon steel sheet stamping and feeding device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution for a motor silicon steel sheet stamping and feeding device, including a base plate 1, a transport frame 4 slidably connected to the upper part of the base plate 1, an mounting plate 5 fixedly connected to one side of the transport frame 4, and two lifting plates 6 slidably connected. Vertical rods 7 distributed at equal intervals are fixedly connected between the two lifting plates 6. Through holes are opened at corresponding positions of the mounting plate 5 and the vertical rods 7 are slidably connected in the cavity of the through holes. A first spring is slidably sleeved on the outside of the vertical rods 7. The first spring is located between the top lifting plate 6 and the mounting plate 5. An mounting frame 8 is installed on the upper part of the base plate 1. An inclined pressure plate 9 that contacts the top lifting plate 6 is installed on one side of the mounting frame 8. An adsorption mechanism is provided at the bottom of the bottom lifting plate 6.

[0025] A stamping machine is installed on one side of the base plate 1. The stamping machine is located on one side of the feeding platform 10. The conveyor frame 4 moves back and forth between the stamping machine and the feeding platform 10 to complete the feeding.

[0026] When the transport frame 4 moves to the unloading platform 10, the top lifting plate 6 descends rapidly under the pressure of the inclined pressure plate 9, and the adsorption mechanism on the bottom lifting plate 6 contacts the silicon steel sheet on the unloading platform 10 and adsorbs the silicon steel sheet. Then the transport frame 4 moves towards the stamping machine. When the lifting plate 6 disengages from the inclined pressure plate 9, the lifting plate 6 rises due to the elastic force of the first spring. At this time, the adsorption mechanism drives the silicon steel sheet to rise, thus completing the process of the transport mechanism adapting to the height difference between the stamping machine and the unloading platform 10.

[0027] like Figure 1 - Figure 4 As shown, a feeding platform 10 is provided above the base plate 1. The feeding platform 10 and the upper part of the base plate 1 are both fixedly connected to two fixed plates 11. Each fixed plate 11 has a sliding groove on one side. Both sides of the feeding platform 10 are provided with cross mechanisms. Both sets of cross mechanisms include two cross-displaced and mutually rotatable inclined rods 12. The two ends of the inclined rods 12 are slidably connected to the two corresponding upper and lower sliding grooves respectively.

[0028] like Figure 3 and Figure 5 As shown, a movable rod 13 is rotatably connected between the bottom ends of the two sets of inclined rods 12. A threaded hole is opened on one side of the movable rod 13. A bidirectional screw 14 is rotatably connected to the upper part of the base plate 1. The two movable rods 13 are threaded onto the outside of the bidirectional screw 14 through their respective threaded holes. Two external threads are provided on the outside of the bidirectional screw 14 in a mirror-symmetrical arrangement. The two movable rods 13 are respectively threaded onto the two external threads.

[0029] like Figure 5 As shown, the upper part of the base plate 1 is rotatably connected to a first worm wheel 15 and a first worm 16 that mesh with each other. One side of the first worm wheel 15 is fixedly connected to one end of the bidirectional screw 14, and the movable end of the first worm 16 is fixedly connected to a gear 17.

[0030] By rotating gear 17, gear 17 drives first worm wheel 15 to rotate via first worm 16. First worm wheel 15 drives two moving rods 13 to move closer or further apart via bidirectional screw 14, thereby driving the moving parts of two sets of cross mechanisms and raising the feeding platform 10.

[0031] like Figure 5 As shown, a rack 18 is provided on one side of the transport frame 4. A linear array of meshing blocks 19 are rotatably connected to one side of the rack 18. A second spring is provided between the movable end of the meshing block 19 and one side of the rack 18. The movable end of the meshing block 19 is meshed with a gear 17. A stop block is fixedly connected to the rack 18 at the corresponding position of each meshing block 19. The stop block is located on one side of the meshing block 19.

[0032] When the transport frame 4 moves and passes the gear 17, it will use the meshing block 19 on the rack 18 to drive the gear 17 to rotate; conversely, when the transport frame 4 returns to its original position, the gear 17 will contact the inclined surface of the meshing block 19, thereby squeezing the meshing block 19 to rotate and squeezing the spring, so that the rack 18 can only drive the gear 17 to rotate in one direction and cannot rotate back.

[0033] like Figure 4 and Figure 5 As shown, a second threaded rod 20 is rotatably connected to one side of the transport frame 4, and a rack rod 18 is threadedly sleeved on the outside of the second threaded rod 20, and the rack rod 18 is slidably connected to one side of the transport frame 4.

[0034] By rotating the second threaded rod 20, the second threaded rod 20 drives the rack rod 18 to slide on the transport frame 4, thereby adjusting the number of meshing blocks 19 that the gear 17 can contact. This allows adjustment of the number of rotations of the gear 17, and thus controls the height of each rise of the unloading platform 10.

[0035] like Figure 1 - Figure 3 As shown, a third threaded rod 21 is rotatably connected to the upper part of the base plate 1. A through threaded groove is provided on one side of the transport frame 4. The transport frame 4 is threadedly sleeved on the outside of the third threaded rod 21 through the threaded groove. A servo motor 2 is installed on the upper part of the base plate 1. The servo motor 2 is electrically connected to the power supply. The servo motor 2 used in this application is a purchased part. It is selected according to the power and size requirements. The control switch system adopts the module provided by the corresponding vendor. This application will not elaborate further. The movable end of the servo motor 2 is fixedly connected to the end of the third threaded rod 21.

[0036] The servo motor 2 drives the third threaded rod 21 to rotate, and the third threaded rod 21 drives the transport frame 4 to move horizontally on the base plate 1.

[0037] like Figure 4 and Figure 5As shown, a second worm 22 and a second worm wheel 23 are rotatably connected to one side of the transport frame 4. One side of the second worm wheel 23 is fixedly connected to one end of the second threaded rod 20. A rocker arm is fixedly connected to the movable end of the second worm 22.

[0038] By rotating the second worm 22, the second worm 22 drives the second threaded rod 20 to rotate via the second worm wheel 23.

[0039] like Figure 1 - Figure 3 As shown, the upper part of the topmost lifting plate 6 is rotatably connected to a roller 3, and the roller 3 is in contact with the bottom of the inclined pressure plate 9.

[0040] The rollers 3 are used to increase the stability of the lifting plate 6 and the inclined pressure plate 9 during lifting.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
