Description

Technical Field

[0001] This utility model relates to the field of automatic shell-fastening equipment technology, and in particular to an automatic iron shell-fastening mechanism. Background Technology

[0002] A single-sided magnet is a magnet that is magnetic on one side and weakly magnetic on the other. The method is to wrap one side of a double-sided magnet with specially treated galvanized iron sheet. In this way, the magnetism of the wrapped side will be shielded, and the magnetic force will be refracted to the other side, thus enhancing the magnetism of the other side.

[0003] Chinese patent CN209887049U discloses an automatic single-sided magnet snap-fit ​​machine. The machine uses a high-pressure air pump to generate gas, which pushes a piston box downward. The downward movement of the piston causes the pressure block at the bottom of the connecting rod to press down on the shell, snapping the shell with the single-sided magnet. This replaces manual snap-fitting and improves the snap-fitting efficiency of the single-sided magnet. The buffering force of the first spring installed inside the two grooves helps to support the shell before snap-fitting. After the snap-fitting is completed, the single-sided magnet is pushed out, making it easy to pick up and put away the single-sided magnet.

[0004] Although the aforementioned patent documents can be used to attach shells to single-sided magnets, the degree of automation is low. Each time the machine is stopped to place the magnets, the shells are attached. This frequent downtime greatly disrupts the continuity of the production process, resulting in a significant reduction in processing efficiency. In large-scale production scenarios, this problem significantly restricts capacity improvement. Utility Model Content

[0005] The purpose of this invention is to address the following shortcomings in the existing technology: low automation, requiring each machine stop for placement and shell fastening, which greatly disrupts the continuity of the production process and leads to a significant reduction in processing efficiency. In large-scale production scenarios, this problem significantly restricts capacity improvement. Therefore, an automatic shell fastening mechanism is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic iron shell fastening mechanism includes a processing table with a rotating hole. A rotating shaft is vertically rotatably installed in the rotating hole. A rotating disk is fixedly installed at the upper end of the rotating shaft. A drive assembly for driving the rotating shaft to rotate is provided on the lower surface of the processing table. Multiple placement slots are equidistantly opened on the circumference of the rotating disk.

[0008] An electro-hydraulic cylinder is installed on the processing table. A pressure rod is installed at the output end of the electro-hydraulic cylinder. A pressure block is fixedly installed at the lower end of the pressure rod. Multiple placement slots can be moved to directly below the pressure block. Positioning blocks are fixedly installed at equal intervals around the lower surface of the rotating disk. A V-shaped groove is opened on the lower surface of the positioning block. A positioning groove is opened in the middle part of the V-shaped groove. A locking component for locking the positioning block is provided on the processing table.

[0009] Preferably, the drive assembly includes a first spur gear fixedly sleeved on a rotating shaft, a stepper motor fixedly mounted on the lower surface of the processing table, and a second spur gear fixedly mounted on one end of the output shaft of the stepper motor, wherein the first spur gear and the second spur gear are meshed together.

[0011] Preferably, the transmission component includes a mounting block fixedly mounted on the side of the pressure rod, a spring rod vertically fixedly mounted on the lower surface of the mounting block, and a top rod fixedly mounted on the lower end of the spring rod, wherein the lower end of the top rod contacts one end of the positioning rod.

[0012] Preferably, the lower surface of the rotating disk has multiple movable holes that are all connected to the placement groove. A movable rod is vertically slidably inserted into each of the multiple movable holes.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-6An automatic iron shell fastening mechanism includes a processing table 1 with a rotating hole. A rotating shaft 2 is vertically rotatably mounted in the rotating hole. A rotating disk 3 is fixedly mounted on the upper end of the rotating shaft 2. A drive assembly for driving the rotating shaft 2 to rotate is provided on the lower surface of the processing table 1. Multiple placement slots 4 are equidistantly opened on the circumference of the rotating disk 3. The drive assembly includes a first spur gear 10 fixedly sleeved on the rotating shaft 2, a stepper motor 11 fixedly mounted on the lower surface of the processing table 1, and a second spur gear 12 fixedly mounted on one end of the output shaft of the stepper motor 11. The first spur gear 10 and the second spur gear 12 are meshed and connected. The stepper motor 11 can rotate intermittently, thereby driving the second spur gear 12 to rotate intermittently. Through the transmission of the first spur gear 10, the rotating shaft 2 and the rotating disk 3 can be driven to rotate intermittently on the processing table 1.

[0026] An electro-hydraulic cylinder 5 is installed on the processing table 1. A pressure rod 6 is installed at the output end of the electro-hydraulic cylinder 5. A pressure block is fixedly installed at the lower end of the pressure rod 6. Multiple placement slots 4 can be moved to the direct underside of the pressure block. Positioning blocks 7 are fixedly installed equidistantly on the lower surface of the rotating disk 3. A V-groove 8 is opened on the lower surface of the positioning block 7. A positioning groove 9 is opened in the middle part of the V-groove. A locking assembly for locking the positioning block 7 is provided on the processing table 1. The locking assembly includes two support blocks 13 that are vertically fixed on the processing table 1, a positioning rod 14 that is rotatably installed between the two support blocks 13, a support block 15 that is fixedly installed on the two support blocks 13, and a transmission component for driving the positioning rod 14 to rotate. One end of the positioning rod 14 is inserted into the positioning groove 9. The transmission component includes a mounting block 16 that is fixedly installed on the side of the pressure rod 6, a spring rod 17 that is vertically fixedly installed on the lower surface of the mounting block 16, and a top rod 18 that is fixedly installed at the lower end of the spring rod 17. The lower end of the top rod 18 is in contact with one end of the positioning rod 14.

[0027] The electro-hydraulic cylinder 5 drives the pressure block to move vertically downwards via the pressure rod 6. Multiple placement slots 4 can be used to place magnets and iron shells to be processed. When the stepper motor 11 rotates intermittently, it can drive one of the placement slots 4 to rotate directly under the pressure block. At this time, the stepper motor 11 stops rotating, and the vertically downward-moving pressure block moves into the placement slot 4, performing shell-locking processing on the magnets and iron shells in the placement slot 4. At the same time, the operator can place other magnets and iron shells to be processed into other placement slots 4, waiting for the rotating disk 3 to move the magnets and iron shells to be processed to be moved directly under the pressure block. Material can be loaded without stopping the machine, avoiding the trouble of placing and locking shells every time the machine is stopped, greatly improving processing efficiency.

[0028] While the pressure rod 6 moves the pressure block vertically downward, it also moves the top rod 18 towards one end of the positioning rod 14. When the top rod 18 contacts one end of the positioning rod 14, it will move one end of the positioning rod 14 towards the positioning block 7. One end of the positioning rod 14 will enter the positioning groove 9 through the V-groove 8. When the pressure rod 6 continues to press down, the spring rod 17 is compressed. Under the restriction of the positioning rod 14 and the positioning groove 9, the rotating disk 3 can be prevented from rotating during the shell-making process. The rotatable connection between the support block 13 and the positioning rod 14 is located in the middle part of the positioning rod 14, biased towards one end. When the top rod 18 does not contact the positioning rod 14, one end of the positioning rod 14 contacts the support block 15, ensuring that the positioning rod 14 is in an inclined state.

[0029] The lower surface of the rotating disk 3 has multiple movable holes that are all connected to the placement slot 4. A movable rod 19 is vertically slidably inserted into each of the multiple movable holes. A lifting block 20 is fixedly installed at the upper end of the movable rod 19, and a cylindrical block 21 is fixedly installed at the lower end of the movable rod 19. A return spring 22 is sleeved on the movable rod 19. The two ends of the return spring 22 are fixedly connected to the cylindrical block 21 and the rotating disk 3, respectively. A guide block 23 with a right-angled trapezoidal longitudinal section is fixedly installed on the processing table 1. A spherical groove is opened on the lower surface of the cylindrical block 21, and a ball bearing 24 is rolled and embedded in the spherical groove. A guide plate 25 is fixedly installed on the processing table 1, and the guide plate 25 is inclined and positioned directly above the rotating disk 3.

[0030] The return spring 22 is in a compressed state, so the lifting block 20 is at the bottom of the placement slot 4. The magnet to be processed and the iron shell are placed on the lifting block 20. After the shell is finished, the rotating disk 3 will drive the processed single-sided magnet to move towards the guide block 23. At this time, the ball 24 installed on the cylindrical block 21 rolls on the inclined surface of the guide block 23. Under the action of the guide block 23, the moving rod 19 moves vertically upward, driving the lifting block 20 to move vertically upward, pushing the processed single-sided magnet out of the placement slot 4. At the same time, the pushed-out single-sided magnet contacts the inclined guide plate 25. Under the action of the guide plate 25, the single-sided magnet moves in the side direction of the rotating disk 3 until it falls off the rotating disk 3. The iron shell can be automatically unloaded without manual removal of the finished product, which greatly saves labor.

[0031] In this invention, multiple placement slots 4 can be used to place magnets and iron shells to be processed. When the drive assembly drives the rotating disk 3 to rotate intermittently, it can drive one of the placement slots 4 to rotate directly under the pressure block. At this time, the rotating disk 3 stops rotating, and the pressure block, which moves vertically downward, moves into the placement slot 4 to perform shell-locking processing on the magnets and iron shells in the placement slot 4. At the same time, the operator can place other magnets and iron shells to be processed in other placement slots 4 and wait for the rotating disk 3 to move the magnets and iron shells to be processed directly under the pressure block. The material can be loaded without stopping the machine, avoiding the trouble of placing and locking the shells every time the machine is stopped, and greatly improving the processing efficiency.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
