Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core production, in particular to an automatic magnetic core pressing machine. Background Art

[0002] When making prefabricated parts for construction, the template needs to be fixed on the prefabricated mold base. Since the flat prefabricated mold base cannot be damaged, a magnetic fixing box is generally used to fix the template.

[0003] Among them, the fixed magnetic box is like the prefabricated fixed magnetic box provided by the utility model with authorization announcement number CN215395874U. The fixed magnetic box consists of an upper cover and a magnetic core installed inside the upper cover by bolts. When in use, the magnetic core is placed in the upper cover, and then the magnetic core is fixed in the upper cover with bolts to form a magnetic box for use.

[0004] Before placing the magnetic core into the upper cover, the magnetic core itself needs to be fixed and installed. Please refer to Figure 5 and Figure 6 The magnetic core is composed of multiple iron blocks and permanent magnet pieces stacked in an alternating manner, wherein the permanent magnet piece is arranged between two iron blocks. Thread grooves are provided on both the iron blocks and the permanent magnet pieces. When assembling the magnetic core, the iron blocks and the permanent magnet pieces are assembled into a magnetic core as a whole by aligning the thread grooves on the iron blocks and the permanent magnet pieces and screwing the connecting bolts into the thread grooves on the iron blocks and the permanent magnet pieces.

[0005] In the prior art, when assembling a magnetic core, a vise is needed to clamp and fix multiple staggered stacked iron blocks and permanent magnet sheets to prevent relative movement between the iron blocks and the permanent magnet sheets, which causes the thread grooves to be misaligned, so that the operator can screw the connecting bolts into the thread grooves. However, when the operator uses the vise to clamp and fix the iron blocks and the permanent magnet sheets, the operator needs to manually adjust the position of each iron block and the permanent magnet sheet to ensure that the thread grooves on the iron blocks and the permanent magnet sheets are aligned. At the same time, when tightening the connecting bolts, it is also necessary to ensure that the side walls of the multiple iron blocks are in the same plane. When the iron blocks and the permanent magnet sheets are positioned by the vise, the multiple iron blocks are prone to offset. The operator needs to specially adjust the flatness between the multiple iron blocks during installation, which increases the labor intensity of the operator and reduces the efficiency of assembling the magnetic core. In view of this, we propose an automatic magnetic core pressing machine. Summary of the Invention

[0008] As a further improvement of the present technical solution, the lifting mechanism includes two side panels fixedly connected to the lower end of the limiting plate. The side panels are arranged below the storage plate, and the side panels have inclined grooves on their side walls. The end of the inclined groove close to the limiting plate is located at a lower position, and the end of the inclined groove away from the limiting plate is located at a higher position.

[0009] As a further improvement of the present technical solution, a U-shaped frame is fixedly connected to the lower surface of the splint, four movable grooves are provided on the storage plate, and the vertical sections of the two U-shaped frames are respectively slidably arranged inside the corresponding movable grooves.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0029] Please refer to Figure 5 and Figure 6 The magnetic core is composed of a plurality of iron blocks 101 and permanent magnet pieces 102 stacked in an alternating manner, wherein the permanent magnet piece 102 is arranged between the two iron blocks 101, and thread grooves are provided on the iron blocks 101 and the permanent magnet pieces 102. When assembling the magnetic core, the thread grooves on the iron blocks 101 and the permanent magnet pieces 102 are aligned, and the connecting bolts 103 are screwed into the thread grooves on the iron blocks 101 and the permanent magnet pieces 102, so that the iron blocks 101 and the permanent magnet pieces 102 can be assembled into a magnetic core as a whole.

[0030] In the prior art, when assembling the magnetic core, a vise is needed to clamp and fix the multiple staggered stacked iron blocks 101 and permanent magnet pieces 102 to prevent relative movement between the iron blocks 101 and the permanent magnet pieces 102, which causes the thread grooves to be misaligned, so that the operator can screw the connecting bolts 103 into the thread grooves. However, when the operator uses the vise to clamp and fix the iron blocks 101 and the permanent magnet pieces 102, the operator needs to manually adjust the position of each iron block 101 and the permanent magnet piece 102 to ensure that the thread grooves on the iron blocks 101 and the permanent magnet pieces 102 are aligned. At the same time, when tightening the connecting bolts 103, it is also necessary to ensure that the side walls of the multiple iron blocks 101 are in the same plane. When the iron blocks 101 and the permanent magnet pieces 102 are positioned by the vise, the multiple iron blocks 101 are prone to offset. The operator needs to specially adjust the flatness between the multiple iron blocks 101 during installation, which increases the labor intensity of the operator and reduces the efficiency of assembling the magnetic core.

[0031] In view of the above problems, please refer to Figure 1-Figure 2As shown, one of the purposes of this embodiment is to provide an automatic magnetic core pressing machine, including an assembly frame 1, a hydraulic cylinder 3 is fixedly connected to the top of the assembly frame 1, a pressure plate 4 is fixedly connected to the lower end of the piston rod of the hydraulic cylinder 3, a storage plate 2 is fixedly connected to the inner wall of the assembly frame 1, the storage plate 2 is used to receive the magnetic core that needs to be pressed, the storage plate 2 is arranged directly below the pressure plate 4, a controller 12 is fixedly connected to the side of the assembly frame 1 away from the baffle 5, the installation position of the controller 12 is higher than the storage plate 2, the hydraulic cylinder 3 is electrically connected to the controller 12, a plurality of iron blocks 101 and permanent magnet pieces 102 are placed on the upper surface of the storage plate 2, and the plurality of iron blocks 101 and permanent magnet pieces 102 are located directly below the pressure plate 4, the iron blocks After the threaded grooves on 101 and the permanent magnet pieces 102 are facing the operator, the operator starts the hydraulic cylinder 3 through the controller 12, so that the piston rod of the hydraulic cylinder 3 is extended to drive the pressure plate 4 to move vertically downward. When the pressure plate 4 contacts the multiple iron blocks 101 and the permanent magnet pieces 102 and applies a certain pressure to the iron blocks 101 and the permanent magnet pieces 102, the pressure plate 4 presses the multiple iron blocks 101 and the permanent magnet pieces 102 to the upper surface of the storage plate 2, thereby achieving rapid fixation of the multiple iron blocks 101 and the permanent magnet pieces 102. At the same time, the pressure plate 4 presses the multiple iron blocks 101 and the permanent magnet pieces 102 so that the bottoms of the multiple permanent magnet blocks are on the same plane, eliminating the trouble of subsequent adjustments by workers. Figure 6 As shown, the connecting bolt 103 required for assembling the magnetic core consists of a screw and a head fixed at one end of the screw. By pressing and fixing multiple iron blocks 101 and permanent magnet pieces 102, it is convenient for the operator to screw the screw of the connecting bolt 103 into the threaded groove on the iron blocks 101 and the permanent magnet pieces 102. When the screw is threadedly connected to the iron block 101 farthest from the operator, the head of the connecting bolt 103 contacts the iron block 101 closest to the operator, and the two outermost iron blocks 101 clamp and fix the remaining iron blocks 101 and permanent magnet pieces 102, so that multiple iron blocks 101 and permanent magnet pieces 102 are quickly assembled into a magnetic core as a whole, thereby improving the efficiency of the operator in assembling the magnetic core.

[0032] To prevent the pressure plate 4 from tilting, a partition 11 is fixedly connected to the inside of the assembly frame 1, and several vertical rods are fixedly connected to the upper surface of the pressure plate 4 near the four corners. The upper ends of the vertical rods pass through the partition 11 and extend to the top of the partition 11. The side walls of the partition 11 and the piston rod of the hydraulic cylinder 3 are slidably set with the partition 11, and the vertical rods are vertically set, so that each part of the pressure plate 4 can only move vertically along the axial direction of the vertical rod, so that the pressure plate 4 can remain in a horizontal state for a long time. When the pressure plate 4 presses and fixes multiple iron blocks 101 and permanent magnet pieces 102, the pressure plate 4 applies the same pressure to the multiple iron blocks 101 and permanent magnet pieces 102, thereby improving the pressing stability of the pressure plate 4 on the multiple iron blocks 101 and permanent magnet pieces 102, making it convenient for operators to assemble the magnetic core.

[0033] When screwing the screw into the thread grooves opened on the multiple iron blocks 101 and the permanent magnet pieces 102, it is necessary to ensure that the thread grooves opened on the multiple iron blocks 101 and the permanent magnet pieces 102 are aligned with each other. Therefore, the operator needs to manually adjust the placement position of each iron block 101 and the permanent magnet piece 102 on the storage plate 2. The manual operation method is relatively cumbersome and increases the labor intensity of the operator. To solve this problem, two clamping plates 6 are symmetrically arranged on the upper surface of the storage plate 2. The two clamping plates 6 are symmetrically fixedly connected to two electric telescopic rods 7 on the side away from each other. The other end of the electric telescopic rod 7 is fixedly mounted on the upper surface of the storage plate 2. The two electric telescopic rods 7 are electrically connected to the controller 12. Then, before the pressure plate 4 is lowered, the operator synchronously starts the two electric telescopic rods 7 through the controller 12. The electric telescopic rods 7 extend and drive the clamping plate 6 to move horizontally toward the iron block 101 and the permanent magnet piece 102. The two clamping plates 6 are used to center the multiple iron blocks 101 and the permanent magnet piece 102 placed between the two clamping plates 6, so that the pressure plate 4 can press and fix the multiple iron blocks 101 and the permanent magnet piece 102 in the middle position on the storage plate 2, eliminating the step of the operator manually adjusting the placement position of the multiple iron blocks 101 and the permanent magnet piece 102, so that the thread grooves on the multiple iron blocks 101 and the permanent magnet piece 102 can be quickly aligned, reducing the labor intensity of the operator.

[0034] When the two clamping plates 6 are in contact with both sides of the multiple iron blocks 101 and the permanent magnet pieces 102 respectively, and the multiple iron blocks 101 and the permanent magnet pieces 102 are placed on the upper surface of the placement plate 2, if there is a large gap between the multiple iron blocks 101 and the permanent magnet pieces 102, that is, when the adjacent iron blocks 101 and the permanent magnet pieces 102 are not in close contact, the operator will not be able to screw the screw into the thread grooves on the multiple iron blocks 101 and the permanent magnet pieces 102. To solve this problem, the placement plate 2 is provided with a plurality of clamping plates 6. A guide groove 22 is provided on the plate 2, and a limit plate 8 is slidingly provided inside the guide groove 22. A baffle 5 is fixedly connected to the upper surface of the storage plate 2. The baffle 5 is in sliding contact with one end of the clamping plate 6. The other ends of the two clamping plates 6 are respectively provided on both sides of the limit plate 8. A lifting mechanism 9 is provided at the lower end of the limit plate 8. When the two clamping plates 6 are close to each other, the lifting mechanism 9 drives the limit plate 8 to move vertically upward. When a plurality of iron blocks 101 and permanent magnet pieces 102 are placed on the upper surface of the storage plate 2, and The plurality of iron blocks 101 and the permanent magnet pieces 102 are positioned between the two clamping plates 6. After the iron block 101 farthest from the operator contacts the side of the baffle 5 close to the clamping plate 6, the plurality of iron blocks 101 and the permanent magnet pieces 102 are aligned and fixed by bringing the two clamping plates 6 close to each other. During this process, the limit plate 8 moves vertically upward. When the upper end of the limit plate 8 moves to the top of the storage plate 2, the upper end of the limit plate 8 and the iron block 101 closest to the operator are close to the operator. one side of the pressing plate 4, thereby preventing the adjacent iron blocks 101 and permanent magnet pieces 102 from moving away from each other when being pushed by the clamping plate 6. At the same time, the heights of the limit plate 8, baffle 5 and clamping plate 6 after moving up are all lower than the thickness of the magnetic core. When the pressing plate 4 punches the magnetic core, the pressing plate 4 will not contact the limit plate 8, baffle 5 and clamping plate 6, ensuring that the pressing plate 4 can press and fix the magnetic core, so that the operator can smoothly screw the screw into the threaded grooves on multiple iron blocks 101 and permanent magnet pieces 102.

[0035] The structure of the lifting mechanism 9 is detailed below. Figure 3 and Figure 4The lifting mechanism 9 includes two side plates 93 fixedly connected to the lower end of the limiting plate 8. The side plates 93 are arranged below the storage plate 2. The side walls of the side plates 93 are provided with inclined grooves 94. The end of the inclined groove 94 close to the limiting plate 8 is located at a low position, and the end of the inclined groove 94 away from the limiting plate 8 is located at a high position. The lower surface of the splint 6 is fixedly connected to a U-shaped frame 91. The storage plate 2 is provided with four movable grooves 21. The vertical sections of the two U-shaped frames 91 are respectively slidably arranged inside the four movable grooves 21. The lower surface of the U-shaped frame 91 is fixedly connected to a slide rod 92. The other end of the slide rod 92 is slidably arranged inside the corresponding inclined groove 94. When the two splints 6 are close to each other, When the two splints 6 move away from each other, the two slide bars 92 respectively move in opposite directions along the inner walls of the two inclined grooves 94, so that the side plates 93 drive the limiting plates 8 to move downward, and the upper end of the limiting plates 8 moves again to the inside of the guide groove 22. When the operator removes the assembled magnetic core from the storage plate 2, the limiting plate 8 is avoided from blocking the movement of the magnetic core, thereby achieving the purpose of facilitating the unloading of the magnetic core.

[0036] When assembling the magnetic core, the operator places multiple iron blocks 101 and permanent magnet pieces 102 on the upper surface of the placement plate 2, so that the multiple iron blocks 101 and permanent magnet pieces 102 are located between the two clamping plates 6, and the baffle 5 blocks the iron block 101 farthest from the operator. Then the piston rod of the hydraulic cylinder 3 is extended to drive the pressure plate 4 to move downward, so that the two clamping plates 6 are close to each other to adjust the position of the multiple magnetic cores combined with each other. The limit plate 8 moves upward to cooperate with the baffle 5 to block the multiple iron blocks 101 and permanent magnet pieces 102 from moving away from or approaching the operator, so that the pressure plate 4 can press and fix the iron blocks 101 and permanent magnet pieces 102 in the predetermined position on the placement plate 2, so that the thread grooves on the multiple iron blocks 101 and permanent magnet pieces 102 are aligned with each other. After the operator screws the screw of the connecting bolt 103 into the thread grooves on the iron blocks 101 and permanent magnet pieces 102, the assembly of the magnetic core is completed.

[0037] The placement plate 2, pressure plate 4, baffle 5, clamping plate 6 and limiting plate 8 mentioned in the present invention are all made of aluminum alloy. The placement plate 2, pressure plate 4, baffle 5, clamping plate 6 and limiting plate 8 cannot be magnetically adsorbed by the iron block 101, thereby avoiding the iron block 101 being adsorbed under the pressure plate 4, thereby avoiding the risk of the iron block 101 falling and being damaged after being lifted to a high place by the pressure plate 4. At the same time, it enables the operator to remove the assembled magnetic core from the upper surface of the placement plate 2 with less effort.
