Description

Technical Field

[0001] The present invention relates to the technical field of drilling positioning, and specifically provides a drilling positioning device for a butterfly valve body. Background Art

[0002] The lug butterfly valve is a common type of butterfly valve, which consists of components such as a valve body, a valve stem, a valve seat, and a sealing ring. The valve body is in the shape of a lug and is usually made of metal or plastic. It is used to control the flow rate of fluids and block or allow fluids to pass through pipelines, and is widely applied in technical fields such as the industrial field, building water supply systems, sewage treatment, fire systems, and the energy industry. When manufacturing a lug butterfly valve, the holes on the valve body are usually precisely manufactured to meet specific working pressure and fluid requirements. These holes require precise drilling processes. Through uniform drilling operations, it can ensure that during the opening and closing processes of the butterfly valve, fluids can flow smoothly through the valve, and it also helps to reduce friction and resistance during the operation of the valve, extending the service life of the valve.

[0003] Publication No. CN118682511A discloses a drilling positioning device for a butterfly valve body, including an installation box body. An inner positioning mechanism for internally positioning the butterfly valve body is installed on the inner bottom surface of the installation box body. Through the installation of the inner positioning mechanism of the present invention, the inner positioning of the lug butterfly valve body is achieved by using three pressing blocks in the inner positioning mechanism, realizing the circumferential primary positioning and clamping. By passing the fixing sleeve through the neck of the valve body and screwing the fixing sleeve with the nut seat using threads, and then sleeving and installing the limit cover on the flange of the valve body neck, the radial secondary positioning and clamping are achieved, improving the stability of the positioning and clamping. Through the installation of the lug limit locking mechanism, the rapid and precise positioning of the lugs is effectively achieved, and the center of the arc-shaped locking plate in the lug limit locking mechanism is collinear with the center of the drill bit on the electric drill body, which is beneficial to quickly and precisely position the drill bit and the lug drilling.

[0004] The above-mentioned drilling positioning device for a butterfly valve body is radially fixed by a rod-shaped structure at the neck of the butterfly valve. Different sizes of butterfly valves require fixing rods with different diameters, and the fixing rods need to be closely fitted with the neck of the butterfly valve during installation to prevent the butterfly valve from shaking during drilling, which greatly increases the cost and installation difficulty in actual use.

A dust-proof housing 703 is fixedly connected to the bottom of the fixed frame 702.

[0028] The movable rod 707 includes a top plate 7071. Two sliders 7072 are fixedly connected to the side of the top plate 7071. A fourth spring 7074 is fixedly connected to the inner side of the sliders 7072. A fixed clamping block 7075 is fixedly connected to the side of the fourth spring 7074. The fixed clamping block 7075 is fixedly connected to the top plate 7071. A pressure rod 7076 is fixedly connected to the bottom of the top plate 7071. A third spring 7073 is fixedly connected to the pressure rod 7076. The bottom of the third spring 7073 is fixedly connected to the fixed frame 702. The threaded drive rod 706 passes through the fixed frame 702 and is fixedly connected to the limit locking mechanism 708 at the bottom.

[0029] The limit locking mechanism 708 includes a drive plate 7081. The drive plate 7081 is fixedly connected to the pressure rod 7076. A third connecting rod 7087 is rotatably connected to the side of the drive plate 7081. A second connecting rod 7086 is rotatably connected to the other side of the third connecting rod 7087. A gear 7085 is fixedly connected to the side of the second connecting rod 7086. A first connecting rod 7082 is rotatably connected to the side of the gear 7085.

[0030] The dust-proof housing 703 includes a housing plate 7031. A center plate 7032 is fixedly connected to the central position inside the housing plate 7031. Connecting grooves 7033 are formed on both the housing plate 7031 and the center plate 7032. The clamping plate 7084 slides inside the dust-proof housing 703 through the limit clamping block 7083.

[0031] In this example, it should be specifically noted that: before drilling, the protruding length of the drill bit 704 is adjusted according to the butterfly valve gear. The second hydraulic device 701 drives the fixed frame 702 to slide outwards to determine the drilling position. During drilling, the motor drives the threaded drive rod 706 to rotate, and the threaded drive rod 706 drives the drill bit 704 to move downwards. The drill bit 704 drives the drive block 711 to move downwards. During the downward movement of the drive block 711, the movable rod 707 is driven to move downwards. The fourth spring 7074 on the movable rod 707 is initially in a contracted state. When the movable rod 707 moves downwards, the pressure rod 7076 drives the drive plate 7081 to move downwards. After being transmitted by the third connecting rod 7087 and the second connecting rod 7086, the drive plate 7081 drives the gear 7085 to rotate. When the gear 7085 rotates, it drives the clamping plate 7084 to move inwards, and the lug on the butterfly valve is clamped by the inward movement of the clamping plate 7084, which can assist in fixing and positioning. When the slider 7072 is driven to move to the installation groove 709 position, the slider 7072 bounces outwards through the fourth spring 7074. At this time, the drive block 711 passes through the middle of the slider 7072, and the drill bit 704 continues to move downwards to drill. The slider 7072 is fixed by the third spring 7073, the fourth spring 7074 and the limit plate 710 at this time, which can prevent the lug from shifting during drilling. After drilling, the drill bit 704 moves upwards through the threaded drive rod 706. After the drive block 711 passes through the slider 7072, the top plate 7071 moves upwards under the action of the third spring 7073, and the fourth spring 7074 is contracted again. The pressure rod 7076 moves upwards to the bottom of the drive block 711 under the action of the third spring 7073, which is convenient for the next drilling.

[0032] Please refer to 1- Figure 11 , an information adjustment system is installed inside the fixed bracket 1. The information adjustment system includes an information collection unit, an information processing unit and a control unit. The information collection unit consists of multiple sensors, including pressure sensors arranged on the outer side of the fixed plate 503, the outer surface of the roller 603 and the inner side of the clamping plate 7084, and an infrared distance measuring sensor on the clamping plate 7084. The information processing unit judges the levelness and verticality of the butterfly valve through the data of the pressure sensors and the infrared distance measuring sensor. The control unit is used to control the coordinated movement of the motor and each hydraulic component, judge the clamping state in the horizontal direction through the pressure sensor on the outer side of the fixed plate 503, judge whether it is vertical through the pressure sensor on the outer surface of the roller 603, and judge the lug clamping state through the pressure sensor and the infrared distance measuring sensor on the clamping plate 7084, so as to carry out fixing and positioning.

[0033] Please refer to 1- Figure 10 , a positioning method for a positioning device of a butterfly valve body drilling, specifically: 1. Preliminary positioning: By rotating the cam 506, the connector 504 is driven to move outwards. The connector 504 drives the fixed plate 503 to move outwards. The fixed plate 503 abuts against the inner wall of the butterfly valve, making the center of the butterfly valve coincide with the center of the drill bit, and preliminarily positioning the butterfly valve. 2. Secondary positioning: The driving mechanism 3 drives the vertical fixing mechanism 6 to move downwards. The sliding plate 602 moves onto the inner wall of the butterfly valve. The sliding plate 602 and the second spring 605 reinforce the butterfly valve in the horizontal direction. At the same time, the roller 603 moves onto the valve body of the butterfly valve to fix the butterfly valve in the vertical direction during drilling. Also, when the driving mechanism 3 rotates for position adjustment, the movement of the roller 603 on the butterfly valve can perform flatness adjustment. Tertiary positioning: During drilling, the lug is clamped on both sides by the limit locking mechanism 708, making the drill bit 704 located at the center of the lug for tertiary positioning.
