Description

Technical Field

[0001] This utility model relates to the field of valve processing equipment, specifically to a drilling machine for processing leak-proof shut-off valves. Background Technology

[0002] A gate valve, also known as a stop valve, is a type of forced-seal valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to ensure a leak-proof seal. Gate valves have inlets and outlets on both sides of the valve body, connected to flanges for a sealed connection to the pipeline. During production, the flanges need to be drilled to create multiple bolt holes for connection.

[0003] In existing processing methods, multi-axis machine tools are often used for machining bolt holes. When machining multiple bolt holes, the valve body or drill bit needs to move in multiple directions to locate the bolt holes, resulting in complex and slow processing steps. Therefore, those skilled in the art have provided a drilling machine for machining leak-proof shut-off valves to solve the problems mentioned in the background art. Utility Model Content

[0005] The mounting frame includes a fixed base, which is fixed to the upper end of the lifting base. A rotating disk is rotatably connected inside the fixed base. A support frame is fixedly connected above the rotating disk. An arc-shaped frame is fixedly connected between the support frames.

The lower end of the pushing block is connected to both ends of the lifting plate.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Please see Figures 1-4 In this embodiment, a drilling machine for processing a leak-proof shut-off valve is provided, including a base 1, a stepping device 2 is installed at one end of the base 1, a drilling device 3 is installed on the stepping device 2, a lifting seat 4 is installed at the other end of the base 1, and a mounting frame 5 is installed on the lifting seat 4.

[0031] The mounting frame 5 includes a fixed base 51, which is fixed to the upper end of the lifting base 4. A rotating disk 52 is rotatably connected inside the fixed base 51. A support frame 53 is fixedly connected above the rotating disk 52. An arc-shaped frame 54 is fixedly connected between the support frames 53. A ring-shaped frame 55 is rotatably connected inside the arc-shaped frame 54.

[0032] A fixed plate 56 is fixedly connected to the lower part of the ring frame 55. A rotating head 57 is rotatably connected to the fixed plate 56. A threaded rod 58 is fixedly connected to the rotating head 57 through the fixed plate 56. A lifting plate 59 is slidably connected to the ring frame 55. A connecting frame 6 is symmetrically fixedly connected to the ring frame 55 above the lifting plate 59. An inclined block 61 is slidably connected to the connecting frame 6. A clamping plate 62 is fixedly connected to one end of the inclined block 61 through the connecting frame 6. A pushing block 63 is slidably connected to the connecting frame 6 below the inclined block 61. The lower end of the pushing block 63 is connected to both ends of the lifting plate 59.

[0033] In use, the rotating head 57 drives the threaded rod 58 to rotate, and the rotation of the threaded rod 58 drives the lifting plate 59 to rise. The rise of the lifting plate 59 drives the pushing blocks 63 on both sides to rise, and the pushing blocks 63 push the inclined block 61 to move towards the center of the ring frame 55. The clamping plate 62 on one side of the inclined block 61 clamps the valve body in the center of the ring frame 55. The drilling equipment 3 drills a hole on one side of the valve body. After drilling is completed, the rotation of the ring frame 55 drives the valve body to rotate together, so that multiple drilling positions on one side of the valve body pass through one side of the drilling equipment 3 in sequence, improving drilling efficiency. After drilling one side, the rotating plate 52 rotates 180 degrees to drill the other side of the valve body.

[0034] In this embodiment, specifically, the stepper device 2 includes a motor, a lead screw, a slide rail, and a saddle, and the drilling equipment 3 is installed on the saddle.

[0035] In this embodiment, a pin is slidably connected to the fixed base 51, and one end of the pin can be inserted into the rotating disk 52. The rotating disk 52 is positioned by inserting the pin into the rotating disk 52.

[0036] In this embodiment, specifically, multiple positioning posts 551 are fixedly connected to the periphery of the annular frame 55. The arc-shaped frame 54 has a first rotating groove 541 and a second rotating groove 542 inside. The annular frame 55 is located inside the first rotating groove 541, and the positioning posts 551 are located inside the second rotating groove 542. The positioning posts 551 rotate together with the annular frame 55 inside the arc-shaped frame 54. Because the spacing between the positioning posts 551 is uniform, the rotation angle of the annular frame 55 can be quickly positioned.

[0037] In this embodiment, specifically, the arc-shaped frame 54 has a slot 543, and a fixing pin 71 is provided inside the slot 543. One end of the fixing pin 71 is inserted into the positioning post 551. By inserting the fixing pin 71 into the positioning post 551, its rotation is restricted. The positioning post 551 thereby restricts the rotation of the annular frame 55, and the annular frame 55 is thus kept fixed together with the valve body.

[0038] In this embodiment, specifically, a connecting plate 7 is fixedly connected between the fixing pins 71. The connecting plate 7 is located on one side of the arc-shaped frame 54 and is slidably connected to the arc-shaped frame 54. A pull rod is fixedly connected to one side of the connecting plate 7. The pull rod can drive the connecting plate 7 to move, and the connecting plate 7 simultaneously drives the fixing pins 71 on both sides to move together and move out of the positioning post 551.

[0039] In this embodiment, specifically, the rotating head 57 has multiple insertion holes around its periphery. Inserting a rod into the insertion hole causes the rotating head 57 to rotate, which in turn causes the threaded rod 58 to rotate.

[0040] In this embodiment, specifically, the lifting plate 59 has slots on both sides, and the slot spacing is the same as the thickness of the ring frame 55. The lifting plate 59 is slidably connected to the ring frame 55 through the slots.

[0041] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
