Description

Technical Field

[0001] This application relates to the field of butterfly valve processing equipment technology, and more specifically, to a single-clamp butterfly valve punching machine for end use. Background Technology

[0002] A butterfly valve is mainly composed of a valve seat, valve body, valve plate, valve stem, and transmission device. The valve plate is the opening and closing element of the butterfly valve, which rotates around the valve stem to achieve the purpose of opening or closing the valve.

[0003] In related technologies, valve seats are generally made of rubber and are fixed by close contact with the inner wall of the valve body. However, this fixing method can easily force axial displacement of the valve seat during fluid flow, thus affecting the sealing performance of the butterfly valve. Therefore, in actual use, threaded holes are made radially on the side of the valve seat, and screws are installed in the threaded holes to limit axial displacement of the valve seat.

[0004] However, traditional drilling rigs are mostly manually operated, making it difficult to ensure the levelness of the borehole. Furthermore, manual drilling is difficult to control, leading to longer construction periods. Utility Model Content

[0005] In view of this, embodiments of this application provide a single-clamp butterfly valve punching machine for the end, to solve the problems in related technologies.

[0016] The lifting mechanism includes a support frame, on which two screws are symmetrically arranged in the vertical direction, and a lifting plate is sleeved between the two screws. The top of the lifting plate is fixedly connected to the linear module.

[0017] The bottom of the screw is equipped with a gear, which is connected to the drive shaft of the second drive motor via a triangular conveyor belt structure; wherein,

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0042] like Figures 1-4 As shown in the embodiment of this application, the single-clamp butterfly valve drilling machine for the end includes a rotary table 100, a pressing mechanism, a linear module 500, and a drilling rig 600. The rotary table 100 consists of a base 110 and a disc 120 rotatably mounted on top of the base 110. The disc 120 can rotate relative to the base 110. A positioning disc 200 is provided in the central area of ​​the top surface of the disc 120. The outer peripheral surface of the positioning disc 200 can fit against the inner wall of the valve seat to achieve radial positioning of the valve seat.

[0043] Preferably, a first drive motor 700 is fixedly mounted on the bottom of the base 110 via a motor mount. The first drive motor 700 can drive the disc 120 to rotate via a gear 830 drive mechanism. Specifically, the first drive motor 700 can be a stepper motor. The output shaft of the stepper motor meshes with the gear ring at the bottom of the disc 120 via a cylindrical gear 830 drive mechanism to drive the disc 120 to rotate uniformly around its own axis.

[0044] The pressing mechanism consists of a column 300 and a hydraulic cylinder 400. The bottom end of the column 300 is fixed and vertically positioned on the edge area of ​​the disc 120, while the top end of the column 300 is connected to the hydraulic cylinder 400 via a connector 310. The hydraulic cylinder 400 extends vertically, and a pressing head 410 is fixedly mounted on the end of its piston rod. This pressing head 410 is located directly above the positioning disc 200, meaning that the pressing head 410 and the positioning disc 200 are concentric. In actual use, the hydraulic cylinder 400 controls the pressing head 410 to move downwards, and the pressing head 410 fixes the valve seat onto the positioning disc 200, facilitating subsequent radial drilling operations. Preferably, a polyurethane buffer layer is provided on the contact surface between the pressing head 410 and the valve seat to prevent excessive compression from damaging the valve seat.

[0045] In this embodiment, a linear module 500 is provided beside the base 110 of the rotary table 100. A drill 600 is fixedly mounted on a slider 510 on the linear module 500 for linear drive. The drill 600 is horizontally fixed to the top of the slider 510 by bolts. In actual use, the drill 600 can be driven to move by manually moving the slider 510 to perform radial drilling on the valve seat using a drill bit. Preferably, the linear module 500 can also be an electrically powered ball screw module.

[0046] In actual use, first determine the inner diameter of the valve seat to be processed, and then fit it onto the positioning plate 200, ensuring that the bottom surface of the valve seat is tightly fitted with the top surface of the disc 120 to avoid radial displacement of the valve seat. Activate the control button of the hydraulic cylinder 400 to extend its piston rod outwards and drive the pressure head 410 to move downwards synchronously. When the pressure head 410 contacts the top surface of the valve seat and reaches the preset pressure, the hydraulic cylinder 400 automatically maintains pressure and fixes the valve seat to the disc 120.

[0047] The slider 510 of the linear module 500 is moved closer to the valve seat, and the drill 600 is started to enter the working state. After the drill bit of the drill 600 reaches the rated speed, the feed program of the linear module 500 is started, and the drill 600 feeds radially into the valve seat along the disc 120 until the preset hole depth is reached and then stops.

[0048] In the single-clamp butterfly valve drilling machine provided in this application embodiment, a linear module 500 is provided beside the base 110 of the rotary table 100. A drill 600 is fixedly mounted horizontally on the top of the slider 510 of the linear module 500, and the drill 600 can achieve drilling feed under the sliding action of the slider 510. With the above structural design, electric drive can be used to replace pure manual operation, thereby shortening the processing time for radial opening of valve seat, reducing the drawbacks of manual intervention, and reducing the labor intensity of manual labor.

[0049] In some embodiments, the central area of ​​the disc 120 is provided with multiple vertically stacked positioning discs 200, the outer diameter of which gradually decreases from top to bottom, to fix valve seats of different sizes. Correspondingly, a lifting mechanism is also provided on the side of the base 110. The lifting mechanism includes a bracket 800, inside which two screws 810 are rotatably mounted in the vertical direction. A lifting plate 820 is threadedly connected to the two screws 810, and the lifting plate 820 is fixedly connected to the linear module 500. Furthermore, gears 830 are provided at the bottom of the two screws 810, and the gears 830 of the screws 810 are connected to the drive shaft of the second drive motor 850 through a triangular conveyor belt structure 840.

[0050] By adopting a lifting mechanism and a multi-gradient positioning plate 200 in a coordinated design, the drilling rig 600 can be raised to a specified height through the lifting mechanism, so that the drill bit of the drilling rig 600 can be matched with the positioning plate 200 at different heights and outer diameters in a timely manner, thereby further enhancing the adaptability of the drilling rig 600 to multiple valve seats.

[0051] In some embodiments, a plurality of roller-type slewing bearings 900 are provided between the base 110 and the disk 120, and each roller-type slewing bearing 900 abuts against the disk 120 via rollers on its top. The roller-type slewing bearings 900 replace traditional sliding friction with rolling friction, which can greatly reduce the coefficient of friction between the bottom of the disk 120 and the top of the base 110. Furthermore, the roller-type slewing bearings 900 can also evenly distribute the load to the base 110, thereby preventing the disk 120 from undergoing concave deformation due to long-term concentrated stress.
