[0013] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0014] This utility model proposes a mechanism for machining internal threads on castings, including a base 1. The base 1 has a sliding plate 3 inside, which serves as a platform for fixing the casting. Vertical plates 2 are integrally designed on both sides of the top of the base 1. Two cylinders 4 are positioned between the two vertical plates 2. Mounting plates 5 are fixedly mounted on the movable ends of the two cylinders 4. Motors 6 are installed through-type on both sides of the interior of the mounting plates 5. A drilling bit 7 and a threading drill bit 8 are respectively mounted on the output ends of the two motors 6. The operation of the cylinders 4 drives the drilling bit 7 downwards, while the motors 6 drive the drilling bit 7 to rotate, thus realizing the drilling operation on the casting. After drilling is completed, the cylinders 4 can be reset, and the sliding plate 3 can be moved to align the hole position on the casting with the threading drill bit 8. Then, the cylinders 4 can be activated again to press down the threading drill bit 8. This enables thread processing of the holes. The inner cavity of the base 1 is equipped with an electric slide table 9. The sliding part of the electric slide table 9 is fixedly connected to the slide plate 3. By controlling the operation of the electric slide table 9, multiple processing of the casting can be achieved by clamping it once. The inner sides of the two vertical plates 2 are each fixedly equipped with an electric slide table 11. The sliding parts of the two electric slide tables 11 are fixedly equipped with mounting brackets 12. Two cylinders 4 are respectively installed through the inner sides of the mounting bracket 12. Under the operation of the electric slide table 11, the drilling bit 7 and the threading bit 8 can be driven to move back and forth. Thus, when drilling at multiple points, the internal thread processing of the casting can also be completed in one go. The inside of the mounting bracket 12 is equipped with a through groove. Both motors 6 can slide into the inner cavity of the through groove. This design has the function of saving space.

[0015] Specifically, side plates 13 are fixedly installed on both sides of the top of the skateboard 3. A screw 14 is threadedly connected to the inside of one of the side plates 13. A clamping plate 15 is rotatably installed at one end of the screw 14 located between the two side plates 13, and a handwheel 16 is fixedly installed at the other end. The casting is placed on the top of the skateboard 3, and the screw 14 is rotated by the handwheel 16 to bring the clamping plate 15 close to the casting and clamp it. The clamping surfaces of the clamping plate 15 and its corresponding side plate 13 are both designed with frosted protrusions to increase friction on the casting.

[0016] Specifically, the inner cavity of the base 1 is fixedly provided with two slide rods 10, which are arranged in parallel and both slide rods 10 are movable through the interior of the slide plate 3. The purpose of this design is to ensure the stability of the movement of the slide plate 3.

[0017] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0018] Working principle: When machining internal threads on a casting, the casting can be placed on top of the slide plate 3, and the screw 14 can be rotated by the handwheel 16 to bring the clamping plate 15 close to the casting and clamp it in place. At this time, the electric slide table 9 is activated according to the drilling point. The operation of the electric slide table 9 can drive the slide plate 3 and the workpiece to move laterally, so that the drilling point is aligned with the drilling drill bit 7 on the same longitudinal line. Then, the electric slide table 11 is activated. The operation of the electric slide table 11 can drive the drilling drill bit 7 to be perfectly aligned with the drilling point. At this time, the motor 6 and the cylinder 4 are activated. The operation of cylinder 4 can drive the drilling bit 7 to move downwards, while motor 6 can drive the drilling bit 7 to rotate, thereby realizing the drilling work on the casting. After the drilling is completed, cylinder 4 can be reset, and electric slide table 9 can be restarted to make the hole position of the casting on slide plate 3 correspond to thread drill bit 8. At this time, cylinder 4 is restarted again to press down thread drill bit 8, thereby realizing the thread processing of the hole position. This processing method can complete the thread processing in one clamping, thereby improving the work efficiency to a certain extent and ensuring the processing quality of internal threads.
