[0002] Reactors are commonly used production equipment in many industries such as chemical, pharmaceutical, and food processing. Their structure is usually quite complex and requires high-level processing technology. During the manufacturing process of reactors, drilling operations are often required in specific parts of the reactor, such as for installing components like stirring shafts, temperature sensor interfaces, and pressure sensor interfaces.

[0003] However, because reaction vessels typically have complex shapes and large dimensions, and require high precision in drilling positions, a positioning device is needed to clamp and limit the reaction vessel body during the machining process to ensure drilling accuracy and prevent opening deviations caused by vessel body offset. Structurally, traditional positioning devices often employ external clamping installation structures. Due to the complex external structure of the reaction vessel (such as ports and lugs), the clamping operation is significantly affected. Furthermore, since the clamping part is located on the periphery of the vessel body, clamping can obstruct the external working surface of the vessel body, affecting the movement of the drilling equipment. Therefore, a drilling positioning device for reaction vessel machining is proposed. Summary of the Invention

Specifically, in order to realize the working drive of the positioning base 4, a rotary drive seat is provided on the upper part of the servo turntable 1, and the positioning base 4 is fixedly installed on the top side of the rotary drive seat.

[0021] The clamping mechanism is used for clamping and supporting the reactor body. The clamping mechanism includes a lifting platform 6, a clamping drive motor 7, a toothed drive column 8, and a clamping support block 9. The lifting platform 6 is guided by the lifting guide column 3 and driven by the lifting drive cylinder 2 to move and lift, and is installed on the upper part of the positioning platform 4. Specifically, see attached... Figure 2 As shown, four lifting guide columns 3 are provided, and the four lifting guide columns 3 are circumferentially distributed and fixedly installed on the upper part of the positioning platform 4, as shown in the attached figure. Figure 4 As shown, in order to cooperate with the lifting guide column 3, a guide column insertion hole 13 is provided on the upper part of the lifting platform 6. The guide column insertion hole 13 is adapted to the lifting guide column 3. The upper part of the lifting guide column 3 is slidably inserted into the guide column insertion hole 13. The lifting drive cylinder 2 can be an electric cylinder. The base side of the lifting drive cylinder 2 is fixedly installed to the top side of the positioning platform 4 by bolts. The upper end of the push rod of the lifting drive cylinder 2 is fixedly installed to the bottom side of the lifting platform 6. The support position inside the clamping support block 9 can be flexibly adjusted by lifting and adjusting. During operation, the support position of the clamping support block 9 can be flexibly adjusted according to the position of the drilling area. While ensuring the stability of the reactor body support, the clamping support block 9 can be avoided from being in the drilling area.

[0022] Four clamping blocks 9 are provided. The clamping blocks 9 are movably and telescopically installed on the outer side of the lifting platform 6 via slotted guides and supports. For details, see attached. Figure 4 As shown, to facilitate the connection and installation of the clamping blocks 9, a circular mounting groove is evenly provided on the outer periphery of the lifting platform 6. The clamping blocks 9 are slidably fitted into the inner side of the mounting groove. Two sets of clamping blocks 9 on opposite sides are arranged in a parallel and staggered manner. The clamping drive motor 7 is used for the working drive of the clamping blocks 9. To improve the driving stability, a reducer 10 is provided on the driving side of the clamping drive motor 7. The base side of the reducer 10 is fixedly installed to the upper part of the lifting platform 6 by bolts. The drive shaft end of the clamping drive motor 7 is fixedly installed to the drive input shaft end of the reducer 10. To realize the working drive of the clamping blocks 9, as shown in the attached figure... Figure 6As shown, a toothed drive column 8 is installed at the lower part of the clamping drive motor 7. The upper end of the toothed drive column 8 is fixedly installed to the drive output shaft end of the reducer 10. The drive gear seat 11 is fixedly installed at the rear end of the clamping support block 9. Two sets of drive gear seats 11 on opposite sides are respectively meshed with the two sides of the toothed drive column 8 through tooth grooves. The clamping support block 9 set on the upper part of the servo turntable 1 is used to position and support the reactor body. The four sets of clamping support blocks 9 are supported by the lifting platform 6 and driven by the clamping drive motor 7. The four sets of clamping support blocks 9 can be realized by the meshing installation of the toothed drive column 8 with the drive gear seat 11 at the end of the clamping support block 9. The synchronous telescopic drive enables stable support and positioning of the reactor body through clamping and support on the inner periphery of the reactor body. The clamping and positioning are precise and can avoid the clamping block 9 occupying the external space inside the reactor body, thus not hindering the movement of the drilling equipment and facilitating the drilling operation. To facilitate clamping and support with the inner periphery of the reactor body, the end of the clamping block 9 is arc-shaped. To improve the stability of the clamping and support, an anti-slip pad 12 is fixedly installed on the end of the clamping block 9. Specifically, the anti-slip pad 12 is made of soft rubber, which can effectively improve the contact friction between the clamping block 9 and the inner wall of the reactor body.

[0023] Working principle or structural principle: During operation, the reactor body is lifted and supported on the upper part of the servo turntable 1. During installation, the initial position of the reactor body is moved and adjusted to avoid excessive offset. Then, the installed reactor body is positioned and adjusted. During operation, the lifting platform 6 is in the lowest position. Then, the clamping drive motor 7 is started to drive the toothed drive column 8 to rotate. Through the meshing transmission between the toothed drive column 8 and the drive tooth seat 11, the four sets of clamping support blocks 9 are synchronously extended and expanded. The four sets of clamping support blocks 9 guide and support the inner periphery of the reactor body to realize the movement and positioning of the reactor body, so that the reactor body and the servo turntable 1 are in a concentric positioning state, completing the initial installation and positioning of the reactor body. After positioning is completed, the support position of the clamping block 9 is determined according to the drilling area distribution of the reactor body. Then, the positioning parameters are input, and the lifting drive cylinder 2 drives the lifting platform 6 to move the clamping block 9 upward. The support position inside the clamping block 9 can be flexibly adjusted by lifting and adjusting. During operation, the support position of the clamping block 9 can be flexibly adjusted according to the drilling area position. While ensuring the stability of the reactor body support, the clamping block 9 can be prevented from being in the drilling area. After reaching the support position, it stops and the clamping drive motor 7 drives the four sets of clamping blocks 9 to extend outward synchronously to complete the stable clamping support on the inner periphery of the reactor body. During the drilling process, the clamping block 9 can avoid occupying the external space inside the reactor body and will not hinder the movement of the drilling equipment, which is conducive to the drilling operation. During drilling, the drilling positioning is completed by the movement of the drilling equipment from the outside. At the same time, the rotation drive of the servo turntable 1 can realize the rotation switching of the reactor body drilling drive to complete the drilling process.

[0024] In summary, this positioning device adopts an internal clamping and support working structure. Clamping blocks 9, located on the upper part of the servo turntable 1, provide positioning and support for the reactor body. Four sets of clamping blocks 9 are supported by a lifting platform 6 and driven by a clamping drive motor 7. Synchronous extension and retraction of the four sets of clamping blocks 9 can be achieved through the meshing of the toothed drive column 8 with the drive tooth seat 11 at the end of the clamping block 9. The clamping support on the inner periphery of the reactor body ensures stable support and limiting of the reactor body. The clamping and positioning are precise, and the clamping blocks 9 can be prevented from obstructing the reactor. The internal and external space will not obstruct the movement of the drilling equipment, which is conducive to the drilling operation. The lifting platform 6 is guided by the lifting guide column 3 and driven by the lifting drive cylinder 2 to move and lift on the upper part of the servo turntable 1. The lifting adjustment can realize the flexible adjustment of the support position inside the clamping block 9. During operation, the support position of the clamping block 9 can be flexibly adjusted according to the position of the drilling area. While ensuring the stability of the reactor body support, it can avoid the clamping block 9 being in the drilling area. The adjustment is convenient and the operation is flexible, which is conducive to improving the flexibility of the device.
