A rotary table bearing block drilling and tapping device

Abstract

This invention discloses a rotary bearing housing drilling and tapping device, including a machine body with a mold mechanism mounted on the top left side of the machine body. The invention utilizes the combined use of the mold mechanism, clamping mechanism, processing mechanism, first mounting mechanism, and second mounting mechanism to automate the production of bearing housings. The produced bearing housings, when rotated by a screw, drive the pressing component downwards, facilitating the fitting of the pressing grooves at the upper and lower positions. This allows for quick installation and removal of the bearings by subsequent workers. Furthermore, if the pressing component has multiple sets of pressing grooves, each set of grooves has a through groove at its top, all of which communicate with oil injection holes. Subsequently, an oil injection nozzle can be directly installed on the oil injection hole, enabling simultaneous oiling of each bearing installed in multiple pressing grooves, increasing the lifespan of each bearing set. This convenient and quick method represents a substantial improvement in the device and the bearing housings it produces, and is suitable for widespread use.

Description

Technical Field

[0001] This invention relates to the field of bearing housing manufacturing technology, specifically to a rotary bearing housing drilling and tapping device. Background Technology

[0002] Currently, bearing housings are widely used in rotating equipment as supporting components for bearings. Bearing housings have concentric holes, which serve as mounting points for the bearings. In rotating equipment requiring high rotational accuracy, heavy loads, or high speeds, it is often necessary to install two or more bearings in the same housing to provide two or more support points for the shaft.

[0003] In existing technology, bearing housings typically consist of an upper housing and a lower housing, with grooves between them for fixing the bearing. However, the connection between the upper and lower housings is achieved using bolts and nuts, requiring a screwdriver for installation. This type of bearing housing is cumbersome. Furthermore, if multiple bearings need to be installed, it is inconvenient for workers to lubricate them simultaneously. Moreover, existing bearing housing machining equipment requires drilling and tapping operations, and the resulting debris is difficult to collect, failing to meet the needs of workers.

[0065] To clearly describe the working principle of this invention, we will use... Figure 1This is explained from a directional perspective, which refers to "front, back, left, and right" as mentioned in the following description, specifically as follows:

[0066] S1. The molten metal raw material is injected into the cavity of the mold body 201 through an external injector. Then, the cover plate 202 is driven to rotate by the output end of the second drive motor 203 to cover the top of the mold body 201. After cooling and forming, the output end of the first electric push rod 205 extends, driving the top plate 204 to move upward and eject the formed metal product.

[0067] S2. The multi-functional robotic arm 101 removes the metal product and places it inside the slot at the top of the turntable 103. By controlling the extension of the output ends of the two sets of second electric push rods 301, the clamping parts 302 on the front and rear sides move closer together, thus clamping and fixing the metal product. The bottom of the metal product is flush with the top of the turntable 103. Figure 13 Medium A-1 state;

[0068] S3. Drive the turntable 103 to rotate 90 degrees counterclockwise through the output terminal of the first drive motor 102, such as Figure 13 In state A-2, the size of the circular hole to be drilled on the metal product is adjusted according to the bearing size to be installed on the bearing housing. First, the output of the second stepper motor 404 drives the second lead screw 402 to rotate, causing the lifting frame 405 to move downward. The bottom opening of the lifting frame 405 fits with the slot on the top of the turntable 103. The output of the third stepper motor 408 drives the third lead screw 406 to rotate, causing the movable plate 409 to move horizontally, so that the center of the third drive motor 410 is located at the center of the circular hole to be drilled. Then, the output of the fourth stepper motor 414 drives the fourth lead screw 412 to rotate, changing the position of the two sets of movable seats 415 on the fourth guide rod 41. The position of the milling head 416 on the third drive motor 410 is such that the distance between the center of the milling head 416 and the center of the third drive motor 410 is adapted to the radius of the circular hole to be cut. The milling head 416 is in a vertical state under the action of the first drive motor 418, while the first tapping head 417 is in a horizontal state under the action of the first drive motor 418. Then, the output end of the cylinder at the bottom of the third drive motor 410 extends, causing the frame 411 to move downward, driving the vertically positioned milling head 416 to contact the top of the metal product. Then, the output end of the third drive motor 410 drives the milling head 416 to "draw a circle" with the center of the third drive motor 410 as the center, thereby realizing the cutting of a circular hole in the metal product. Figure 13 A-3 status;

[0069] S4. Next, the milling head 416 in the milling and tapping assembly continues to create annular grooves B-1 on the inner wall of the opened circular hole. The width of the grooves B-1 is adapted to the width of the bearing to be installed in the bearing housing. The milling head 416 is in a horizontal state, which can be achieved by "drawing a circle" with the center of the third drive motor 410 as the center. The number of grooves B-1 can be machined on the inner wall of the circular hole according to the number of bearings to be installed in the bearing housing to be produced.

[0070] S5. Next, a through groove is machined at the highest point of each pressure groove B-1. This can be achieved using the milling head 416 in the milling and tapping assembly. The milling head 416 is in a horizontal position. Then, the milling head 416 is used to open an oil injection hole B-4 on the metal product. At this time, the milling head 416 is in a vertical position. Then, the first tapping head 417 in a vertical position is used to machine a thread inside the oil injection hole B-4. The oil injection hole B-4 is connected to each set of through grooves. Therefore, the oil injection nozzle can be directly installed on the oil injection hole B-4 to realize synchronous oil injection of each set of bearings installed inside the pressure groove B-1, which increases the life of each set of bearings and is convenient and quick.

[0071] S6. Next, the milling head 416 in the milling and tapping assembly is still used to cut an elongated hole in the metal product, such as... Figure 13 In state A-4, the metal product is still being cut to form pressed part B-2, which is... Figure 13 In state A-5, and to prevent the cut pressing part B-2 from falling off, during the cutting process, the output ends of the third electric push rods 307 on both sides are extended, so that the two sets of clamping blocks 312 on both sides are close to the metal product. Then, the output ends of the first step motors 303 on both sides are controlled to rotate synchronously, so that the movable block 306 moves back and forth, driving the two sets of clamping blocks 312 on both sides to move back and forth and move to the appropriate position. Through the synchronous rotation of the output ends of the servo motors 311 on both sides, the two sets of clamping blocks 312 on both sides move closer to each other, clamping the pressing part B-2 in advance to prevent it from falling off, thus improving the rigor of the processing design.

[0072] S7. The drilling and tapping components on the left and right sides inside the lifting frame 405 are processed simultaneously. The drilling and tapping component on the left first drills the mounting hole B-3 on the top of the metal product and the top of the pressure piece B-2, and then drills the thread in the mounting hole B-3. Since both sides of the pressure piece B-2 are clamped and fixed by two sets of clamping blocks 312, the force is more uniform, which improves the stability of drilling and tapping. The drilling and tapping component on the right first drills two sets of mounting grooves B-7 on the bottom of the metal product, and then drills the thread in the mounting groove B-7 to facilitate the subsequent installation and fixing of the bearing seat.

[0073] It is worth noting that the present invention also includes a detachable collection box 105. After installation, the collection box 105 is attached to the bottom of the turntable 103, so that the debris generated during cutting, drilling and tapping will automatically fall into the collection box 105 for collection, ensuring a clean processing environment. The collected metal can also be used for subsequent smelting, saving resources.

[0074] S8. After that, the lifting frame 405 moves upward under the drive of the output end of the second stepper motor 404. It continues to drive the turntable 103 to rotate counterclockwise by 90 degrees through the output end of the first drive motor 102. The multi-functional robotic arm 101 places the external screw B-6 at the electric screwdriver bit 505. The electric screwdriver bit 505 magnetically attracts it. With the cooperation of the output end of the fifth electric push rod 502 and the output end of the fifth drive motor 504, the screw B-6 rotates and faces the pressing part B-2. This realizes the installation of the screw B-6 inside the mounting hole B-3 of the metal product. However, the bottom of the screw B-6 does not enter the mounting hole B-3 opened at the top of the pressing part B-2.

[0075] S9. Next, the output end of the first drive motor 102 drives the turntable 103 to rotate counterclockwise by 90 degrees. The multi-functional robotic arm 101 places the inner ring of the self-made bearing B-5 onto the bottom of the screw B-6. With the cooperation of the output ends of the sixth electric push rod 602 and the seventh electric push rod 604, the center of the rotating gear ring 606 is made concentric with the center of the screw B-6. Then, by adjusting the angle of the welding head 607, it is aligned with the connection between the inner ring of the self-made bearing B-5 and the screw B-6. Under the action of the output end of the second drive motor 609, the self-made bearing B-5 and the screw B-6 are welded together.

[0076] S10. The output end of the first drive motor 102 drives the turntable 103 to rotate 90 degrees clockwise, so that it returns to the first mounting mechanism 5. Repeat the above operation so that the screw B-6 continues to move closer to the pressure piece B-2, thereby allowing the self-made bearing B-5 connected to the bottom of the screw B-6 to enter the mounting hole B-3 opened on the top of the pressure piece B-2.

[0077] S11. Finally, the output of the first drive motor 102 drives the turntable 103 to rotate 90 degrees counterclockwise. The above operation is repeated, adjusting the angle of the welding head 607 to align it with the connection point between the outer ring of the self-made bearing B-5 and the pressure piece B-2, thus completing the automated production and processing of the bearing housing. The bearing housing appears as follows... Figure 14 As shown.
