Description

Technical Field

[0001] This invention belongs to the field of press fitting machines, specifically a material control device and a press fitting machine. Background Technology

[0002] Currently, most motor rotors are manufactured by stacking several silicon steel sheets together and connecting them in series by passing a shaft through the central hole of the stacked silicon steel sheets. However, existing rotor lamination press machines, as described in paragraph 0044 of the specification of patent number CN117266A, use a storage mechanism composed of several small, identical storage mechanisms to facilitate the storage of large quantities of silicon steel sheets and reduce the number of feeding operations. These small storage mechanisms are all mounted on a support frame, which elevates them. The storage rack is used to store and fix the silicon steel sheets. During operation, a certain number of silicon steel sheets are stacked together, and through a through-hole, the silicon steel sheets pass through the storage seat and fall into the pushing device. This design has the following problems:

[0003] 1. When repairing, maintaining or servicing the second pushing device, it needs to be pulled out from below the first through hole. Since there is no control or stop device in the second pushing device, the silicon steel sheet located in the small storage mechanism is prone to falling out of the first through hole. To prevent this from happening, the silicon steel sheet in the small storage mechanism needs to be removed first or something else needs to be used to temporarily block the area below the first through hole, which increases unnecessary workload.

[0004] 2. Since the small storage mechanisms are all fixedly installed on the support frame, and each small storage mechanism is quite high, when it is necessary to load materials, the operator's height cannot adapt to this height. They can only use other equipment, such as stools, to raise the height of the small storage mechanism to adapt to the height of the small storage mechanism. Loading materials is troublesome and takes a long time, which leads to long waiting time for the equipment and low production efficiency. Summary of the Invention

[0023] (3) Beneficial effects

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. This invention sets the clamping plate closer to the opening and closing device, causing the left and right stops to move away from each other and open up. This allows the silicon steel sheet to fall down along the Z-axis guide hole. At this time, the left stop compresses the left elastic element, and the right stop compresses the right elastic element. The telescopic driver is activated, causing the telescopic rod to move the clamping plate away from the opening and closing device. The left elastic element resets the left stop, and the right elastic element resets the right stop, thus stopping the silicon steel sheet on the storage device. When the equipment needs inspection and maintenance, feeding can be paused directly without emptying all the silicon steel sheets in the storage device. The opening and closing device and telescopic device enable automated control of the feeding quantity, feeding start or pause, simplifying maintenance, saving time and effort, and effectively improving the functional quality of the equipment.

[0026] 2. This invention uses a guide rod to suspend and fix the material onto the support structure. The lower end of the guide rod can extend into the Z-axis guide hole, allowing some silicon steel sheets to directly enter the Z-axis guide hole. The material is fed in two ways, making the whole process simple, fast, and convenient. It can complete the feeding without the need for other tools, saving feeding waiting time and improving production efficiency. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention;

[0038] Please see Figure 1-9 ;

[0039] like Figures 1-2As shown, a material control device and pressing machine include an opening and closing device 1 and a telescopic device 2. The telescopic device 2 includes a telescopic driver 21, a telescopic rod 22, and a clamping plate 23. The opening and closing device 1 includes a left stop block 11, a left elastic element 12, a right stop block 13, and a right elastic element 14. A material storage device 3 is provided above the opening and closing device 1. A guide block 4 is provided on one side of the telescopic device 2. The guide block 4 has a Z-axis guide hole 41. It should be noted that the material storage device 3 is used to store a large number of silicon steel sheets. 5. The opening and closing device 1 is used to stop the silicon steel sheet 5 from falling into the storage device 3 or to release the silicon steel sheet 5. The telescopic device 2 enables the opening and closing device 1 to open so that the silicon steel sheet 5 can fall or close to stop the silicon steel sheet 5 and prevent it from falling. The left stop block 11 and the right stop block 13 are symmetrically arranged in the guide block 4. One end of the left elastic element 12 is fixedly connected to the left stop block 11 and the other end is fixedly connected to the guide block 4. The right elastic element 14 is fixedly connected to the right stop block 13 and the other end is also fixedly connected to the guide block 4. A fixed connection is established, with the telescopic rod 22 and the clamping plate 23 fixedly connected. Activating the telescopic driver 21 causes the telescopic rod 22 to move the clamping plate 23 towards the opening / closing device 1, causing the clamping plate 23 to move the left stop 11 and right stop 13 away from each other and open, allowing the silicon steel sheet 5 to fall downwards along the Z-axis guide hole 41. At this time, the left stop 11 compresses the left elastic element 12, and the right stop 13 compresses the right elastic element 14. Activating the telescopic driver 21 causes the telescopic rod 22 to move the clamping plate 23 towards the opening / closing device 1. When the closing device 1 moves away in the opposite direction, the left elastic element 12 resets the left stop 11, and the right elastic element 14 resets the right stop 13, thus stopping the silicon steel sheet 5 located on the storage device 3. When the equipment needs to be inspected or maintained, feeding can be stopped directly without having to empty all the silicon steel sheets 5 in the storage device 3. The opening and closing device 1 and the telescopic device 2 enable automated control of the feeding quantity, start feeding or stop feeding, making maintenance easier, saving time and effort, and effectively improving the quality of equipment function.

[0040] like Figures 2-5As shown, the guide block 4 has an X-axis through hole 42 and a Y-axis through hole 43. One end of the left elastic element 12 is fixedly fitted with a left plate 15, and the other end of the left elastic element 12 is fixedly fitted with a left stop block 11. One end of the right elastic element 14 is fixedly fitted with a right plate 16, and the other end is fixedly fitted with a right stop block 13. It should be noted that the left elastic element 12 and the right elastic element 14 are installed in the X-axis through hole 42, fixing the left plate 15 and the right plate 16 to the guide block 4 and blocking both ends of the X-axis through hole 42. The left stop block 11 and the right stop block 13 are installed in the Y-axis through hole 43, and have... In the partially movable space, when the clamping plate 23 approaches a certain position in the direction of the Y-axis through hole 43, the clamping plate 23 moves the left stop 11 and the right stop 13 away from each other and opens them up. The left elastic element 12 and the right elastic element 14 are compressed in the X-axis through hole 42, releasing the silicon steel sheet 5 located in the Z-axis guide hole 41 and letting it fall downwards. When the clamping plate 23 moves away from the Y-axis through hole 43 to a certain position, the left elastic element 12 and the right elastic element 14 return to their original state in the X-axis through hole 42, causing the left stop 11 and the right stop 13 to reset and block the silicon steel sheet 5 located in the Z-axis guide hole 41.

[0041] Specifically, the left stop 11 is provided with a left arc groove 111, and the right stop 13 is provided with a right arc groove 131. The left arc groove 111 and the right arc groove 131 are equal in size and symmetrically arranged. When the left stop 11 and the right stop 13 are closed, the left arc groove 111 and the right arc groove 131 form a hole smaller than the outer circumference of the silicon steel sheet 5, preventing the silicon steel sheet 5 from falling. When the left stop 11 and the right stop 13 are far apart in the Y-axis through hole 43 and are in an open state, a hole larger than the outer circumference of the silicon steel sheet 5 is formed between the left arc groove 111 and the right arc groove 131, allowing the silicon steel sheet 5 to fall to the bottom under its own gravity.

[0042] Such as Figures 6-8As shown, the storage device 3 includes a support structure 31, a guide rod 32, a counterweight block 33, and a limiting block 34. The support structure 31 is provided with a limiting hole 311, and a limiting groove 312 adapted to the size of the limiting block 34 is provided on the edge of the limiting hole 311. A first opening 313 is provided on one side of the limiting hole 311. The limiting block 34 is provided with two small holes 341. The counterweight block 33 is provided with two small holes 331. The silicon steel sheet 5 is... The device has a main hole 51, several side holes 52, and a second opening 53 on the edge of each side hole 52. It should be noted that there are two guide rods 32, and their size is smaller than the side holes 52. In this embodiment, the material storage device 3 can be loaded in two ways. The first way is to place the guide rods 32 flat on the worktable, then align the side holes 52 of the silicon steel sheet 5 with the guide rods 32 and insert them symmetrically. The guide rods 32 serve to store a large number of silicon steel sheets 5 and guide them. After the silicon steel sheets 5 are fully stacked on the guide rod 32, align the small hole 331 with the guide rod 32 and place it on the silicon steel sheets 5, which will press the silicon steel sheets 5 down along the guide rod 32. Then, push the guide rod 32 with the silicon steel sheets 5 and the counterweight 33 vertically into the limiting hole 311, aligned with the first opening 313. At this time, the counterweight 33 is located below the limiting hole 311, and the lower end of the guide rod 32 extends into the Z-axis guide hole 41, so that part of the silicon steel sheets 5 directly enters the Z-axis. Inside the guide hole 41, a small hole 341 is set, slightly smaller than the size of the guide rod 32. When the guide rod 32 is aligned with the small hole 341 and inserted into it, the small hole 341 exerts a partial gripping force on the guide rod 32, allowing the guide rod 32 to be suspended and fixed on the support structure 31. Then, the limiting block 34 is placed on the limiting groove 312 to prevent the guide rod 32 from falling out of the limiting hole 311, making it convenient to fix the guide rod 32 on the support structure 31 or remove it for feeding. The second method involves first securing the limiting block 34 to one end of the guide rod 32, then inserting the counterweight block 33 onto the guide rod 32 before feeding. Once the silicon steel sheets 5 are fully stacked on the guide rod 32, use your hand or other object to hold the lower end of the guide rod 32 upright and suspend it on the support structure 31 for fixation. At this point, the lower end of the guide rod 32 can extend into the Z-axis guide hole 41, allowing some of the silicon steel sheets 5 to directly enter the Z-axis guide hole 41. Both methods of feeding are simple, quick, and convenient, requiring no additional tools to complete the feeding process, saving feeding waiting time and improving production efficiency.

[0043] Specifically, since the guide rod 32 is a suspended fixed setting, in order to prevent the silicon steel sheet 5 from not being able to smoothly enter the Z-axis guide hole 41, a guide strip 44 is provided below the guide rod 32. The Z-axis guide hole 41 is provided with a long groove 411. The number of guide strips 44 and long grooves 411 is two. The guide strip 44 is inserted into the long groove 411 and fixed on the guide block 4. At this time, the guide strip 44 and the guide rod 32 are aligned vertically. Under the action of the weight block 33, the silicon steel sheet 5 located on the guide rod 32 smoothly enters the Z-axis guide hole 41 through the long groove 411 through the side hole 52 of the silicon steel sheet 5 through the weight block 33, and then waits for the opening and closing device 1 to open and fall.

[0044] like Figure 9 As shown, since the rotor is made by stacking several silicon steel sheets 5 together, for example, stacking 10 silicon steel sheets 5 together to obtain a silicon steel sheet group 54, and connecting them in series by passing the shaft core through the main hole 51 of the stacked silicon steel sheet group 54, a pushing device 6 is provided below the guide block 4. The pushing device 6 includes a push rod 61, a guide hole 62 and a viewing hole 621. A thickness adjustment device 7 is provided below the guide hole 62. The thickness adjustment device 7 is activated to extend and retract within the guide hole 62 to adjust to the height required for the rotor lamination. When the opening and closing device 1 is opened, the silicon steel sheets 5 fall from the guide support rod 32 along the Z-axis guide hole 41 into the guide hole 62. The falling situation is observed through the viewing hole so as to adjust the state of the silicon steel sheets 5 in the guide hole 62 in time, forming a group of silicon steel sheets 5. Subsequently, the push rod 61 pushes the group of silicon steel sheets 5 to be assembled with the shaft core.
