Description

Technical Field

[0001] This utility model relates to the field of magnetic yoke production technology, and more specifically, to an automated production line for magnetic yoke production. Background Technology

[0002] A magnetic yoke is a device used to concentrate and guide a magnetic field. It is typically made of ferromagnetic materials, such as steel or nickel-iron alloys. As an important magnetic component, the magnetic yoke is widely used in electromagnetic brakes.

[0003] refer to Figures 1-4 The magnetic yoke 15 in an electromagnetic brake typically has a central hole 152, an annular groove 151 for mounting a coil on one side, and a lead hole 156 connecting the annular groove 151 on the other side. It also has through holes 154 and threaded holes 155 on both sides for connecting other parts. The machining of the magnetic yoke 15 generally involves the following main steps: rough turning (rough turning of both end faces, the central hole 152, and the annular groove 151); front drilling and tapping (drilling and tapping the bottom holes of the arc-shaped groove 153, the through hole 154, and the threaded hole 155 on the front); back drilling and tapping (drilling and tapping the bottom holes of the through hole 154 and the threaded hole 155 on the back); side drilling (drilling the lead hole 156 connecting the annular groove 151); and finish turning (finish turning of both end faces, the central hole 152, and the annular groove 151).

[0004] Currently, the machining of magnetic yokes involves different steps on different processing equipment, which usually requires manual loading, unloading and material transfer. This not only results in high labor intensity but also low production efficiency. Utility Model Content

Detailed Implementation

[0023] refer to Figure 5 An automated production line for producing magnetic yokes includes four stations: a first station 1, a second station 2, a third station 3, and a fourth station 4. The first station 1 is used for rough turning, specifically rough turning the two end faces, the center hole 152, and the annular groove 151. The second station 2 is used for drilling and tapping the front side, specifically drilling and tapping the bottom holes of the arc-shaped groove 153, through hole 154, and threaded hole 155 on the front side. The third station 3 is used for drilling and tapping the side and back sides, specifically drilling and tapping the bottom holes of the through hole 154 and threaded hole 155 on the back side. The fourth station 4 is used for finish turning, specifically finish turning the two end faces, the center hole 152, and the annular groove 151.

[0024] Each workstation is equipped with corresponding processing equipment. In this embodiment, each workstation uses highly automated equipment. Specifically, the processing equipment for the first workstation 1 is a CNC lathe 12; the processing equipment for the second workstation 2 is four drilling and tapping centers 13; the processing equipment for the third workstation 3 is a drilling and tapping center 14 equipped with a side milling head (which makes it possible to form side drilling and back drilling in one step); and the processing equipment for the fourth workstation 4 is a CNC lathe 12.

[0025] The first workstation 1 has a first hopper 5. The second workstation 2 shares a second hopper 6 with the first workstation 1. The third workstation 3 shares a third hopper 7 with the second workstation 2. The fourth workstation 4 shares a fourth hopper 8 with the third workstation 3. The fourth workstation 4 also has a fifth hopper 9. It's easy to understand that the first hopper 5 is used to hold workpiece blanks, the second hopper 6 is used to temporarily store semi-finished products processed at the first workstation 1, the third hopper 7 is used to temporarily store semi-finished products processed at the second workstation 2, the fourth hopper 8 is used to temporarily store semi-finished products processed at the third workstation 3, and the fifth hopper 9 is used to hold finished products. Each hopper is independent. When one workstation is being debugged, if there is material in the other independent hoppers, the production line will not stop waiting due to lack of material, and it will not affect the operation of other workstations.

[0026] Each workstation is equipped with a robot 11. Each workstation uses the robot 11 to load and unload materials for its corresponding processing equipment between adjacent hoppers. This allows for continuous operation of each process without the need for manual loading, unloading, and workpiece transfer, reducing labor intensity and increasing production efficiency. Furthermore, in the third workstation 3, back-side drilling and tapping are performed together with side drilling, reducing inter-process transfers and further improving production efficiency.

[0027] The first station 1 is equipped with two CNC lathes 12, the second station 2 is equipped with four drilling and tapping centers 13, the third station 3 is equipped with one drilling and tapping center 13 with a side milling head, and the fourth station 4 is equipped with two CNC lathes 12. The robot 11 includes a robotic arm and a base. The robotic arm is rotatably mounted on the base, meaning it can rotate 360 ​​degrees on the base. The bases of the robot 11 in the first station 1, the third station 3, and the fourth station 4 are fixedly installed. Since the second station 2 has four drilling and tapping centers 13, in this embodiment, the second station 2 is equipped with a guide rail 10 along the line connecting the first station 1 and the third station 3. The base of the robot 11 in the second station 2 is slidably mounted on the guide rail 10, ensuring that each drilling and tapping center 13 can be loaded and unloaded by the robot 11.

[0028] As an alternative, in the second station 2, two drilling and tapping centers 13 are located on one side of the guide rail 10, and the other two drilling and tapping centers 13 are located on the other side of the guide rail 10. This arrangement makes full use of the space and minimizes the area occupied by the second station 2. Furthermore, in the first station 1 and the fourth station 4, two CNC lathes 12 are located on opposite sides of the robot 11. Similarly, this arrangement also makes full use of the space.

[0029] In this embodiment, the second hopper 6 is located at the first work station 1, and the third hopper 7 and the fourth hopper 8 are located at the third work station 3. That is, the second hopper utilizes the space of the first work station 1, and the third hopper 7 and the fourth hopper 8 utilize the space of the third work station 3. This arrangement can also make full use of the space.

[0030] As an alternative, the lines connecting the first station 1, the second station 2, and the third station 3 form a first straight line, and the lines connecting the fourth station 4 and the third station 3 form a second straight line. The second straight line is perpendicular to the first straight line, meaning the four stations are arranged in an "L" shape (or a "7" shape). In practical applications, the two CNC lathes 12 at the fourth station 4 are arranged close to the fourth material bin 8, ensuring that the fourth station 4 and the third station 3 can share the fourth material bin 8. In other embodiments, the four stations can also be on a straight line. In this case, a guide rail 10 can be added to the third station 3, allowing the robot 11 to move along the line connecting the third station 3 and the fourth station 4, so that the third station 3 and the fourth station 4 can share the fourth material bin 8.

[0031] In practical applications, the continuity and efficiency of processing can be maximized by matching the production cycle time. For example, at the first station 1, two CNC lathes 12 can rough-turn both ends of the workpiece, taking a total of 1 minute; at the second station 2, four drilling and tapping centers 13 can independently process a workpiece, taking a total of 4 minutes; at the third station 3, one drilling and tapping center 14 equipped with a side milling head takes 1 minute; and at the fourth station 4, two CNC lathes 12 can finish-turn both ends of the workpiece, taking a total of 1 minute. In other embodiments, the processing time of each station can be configured with a corresponding number of processing devices.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
