Description

Technical Field

[0001] This utility model relates to the field of valve manufacturing equipment technology, and in particular to a valve mounting hole drilling and grinding equipment. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves are used in fluid control systems, and the valve mounting hole is a key part to ensure the sealing and reliability of the connection between the valve and the pipeline or equipment. Its machining accuracy (such as hole diameter tolerance, perpendicularity, and surface roughness) directly affects the assembly quality of the valve.

[0003] To improve the machining accuracy of mounting holes and reduce process steps, drilling and grinding equipment is used for drilling and grinding mounting holes in valve bodies (such as ball valves and gate valves). By integrating drilling and grinding, the sealing connection requirements between valves and pipelines can be met. However, valve mounting holes are mostly circumferentially distributed, such as the multiple bolt holes of flange valves. Traditional processing equipment requires multiple disassemblies and repositioning of the valve to complete the machining of different hole positions, resulting in low efficiency and poor hole position accuracy, which restricts the quality of valve assembly. Therefore, we propose a valve mounting hole drilling and grinding equipment to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a valve mounting hole drilling and grinding equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A valve mounting hole drilling and grinding equipment includes a processing table. A rear support plate is fixedly connected to the upper surface of the processing table. A drilling and grinding mechanism and a guide assembly are fixedly connected to the outer surface of the rear support plate. A bottom ring slide rail is fixedly connected to the upper surface of the processing table. A sliding support cylinder is slidably connected inside the bottom ring slide rail. A placement platform is fixedly connected to the top of the sliding support cylinder. A drive motor is fixedly connected to the upper surface of the processing table. A square connecting plate is fixedly connected to the output end of the drive motor. Both ends of the square connecting plate are fixedly connected to the inner wall of the sliding support cylinder. Two fixing plates are fixedly connected to the upper surface of the placement platform. A square box is fixedly connected to the outer surface of each fixing plate. An electric cylinder is fixedly connected to the inner wall of each square box. A sliding seat is fixedly connected to the output end of each electric cylinder. A V-shaped clamping block is bolted to the outer surface of each sliding seat.

[0006] In a further embodiment, a main slide rod is fixedly connected to one of the adjacent sides of the two fixed plates, and the main slide rod is slidably connected to the two sliding seats.

[0007] In a further embodiment, a side support is fixedly connected to the bottom surface of the processing table.

[0008] In a further embodiment, the drilling and grinding mechanism includes an electric push rod fixedly connected to the upper surface of the rear support plate. The output end of the electric push rod is fixedly connected to a connecting frame. A rotary motor is fixedly connected to the inner wall of the connecting frame. A grinding head is fixedly connected to the output end of the rotary motor. A drill bit is fixedly connected to the bottom end of the grinding head.

[0009] In a further embodiment, a diagonal brace is fixedly connected to the outer surface of the rear support plate, and the diagonal brace is inclined.

[0010] In a further embodiment, the guide assembly includes a fixing ring fixedly connected to the outer surface of the rear support plate, a sliding column slidably connected inside the fixing ring, a connecting plate fixedly connected to the bottom end of the sliding column, and the outer surface of the connecting plate fixedly connected to the outer surface of the connecting frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device uses a drive motor to rotate a square connecting plate and a sliding support cylinder along a bottom ring slide rail, causing the valves on the platform to rotate synchronously. This enables continuous processing of multiple holes with a single fixation, saving time compared to traditional disassembly and positioning processing methods, thus improving processing efficiency. Furthermore, the fixed rotation center significantly improves the concentricity and spacing between the holes and the valve center, resolving the problem of poor accuracy from multiple positioning operations. It is particularly suitable for processing circumferentially distributed holes, achieving rotary processing without the need for repositioning, improving both efficiency and accuracy. Meanwhile, an electric cylinder drives a sliding seat to move along the main slide rod, causing a V-shaped clamping block to clamp valve bodies of different diameters, avoiding positioning deviations caused by differences in valve specifications and meeting the stringent requirements for valve sealing connections.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 In this utility model, a valve mounting hole drilling and grinding equipment includes a processing table 1. A rear support plate 3 is fixedly connected to the upper surface of the processing table 1. A drilling and grinding mechanism 4 and a guide assembly 5 are fixedly connected to the outer surface of the rear support plate 3. A bottom ring slide rail 7 is fixedly connected to the upper surface of the processing table 1. A sliding support cylinder 8 is slidably connected inside the bottom ring slide rail 7. A platform 11 is fixedly connected to the top of the sliding support cylinder 8. A drive motor 9 is fixedly connected to the upper surface of the processing table 1. A square connecting plate 10 is fixedly connected to the output end of the drive motor 9. Both ends of the square connecting plate 10 are fixedly connected to the inner wall of the sliding support cylinder 8. The upper surface of the platform 11 is fixedly connected to... Two fixed plates 12 are connected, and a square box 15 is fixedly connected to the outer surface of each fixed plate 12. An electric cylinder 16 is fixedly connected to the inner wall of each square box 15. A sliding seat 14 is fixedly connected to the output end of each electric cylinder 16. A V-shaped clamping block 17 is bolted to the outer surface of each sliding seat 14. The drive motor 9 drives the valve to rotate to achieve continuous processing of multiple holes without repositioning. The V-shaped clamping block 17 is adaptable to different valves, solving the problems of low efficiency and poor accuracy of traditional multiple positioning, laying the foundation for efficient processing. Moreover, the adjustable V-shaped clamping block 17 is adaptable to valves of different diameters without the need to change the fixture.

[0019] Two fixed plates 12 are fixedly connected to a main slide rod 13 on their adjacent sides. The main slide rod 13 is slidably connected to two sliding seats 14. The main slide rod 13 limits the movement trajectory of the sliding seats 14, ensuring that the V-shaped clamping block 17 is horizontally stable when it moves, such as being parallel to the surface of the platform 11, and avoiding valve center offset due to tilting, such as deviating from the rotation center. The bottom surface of the processing table 1 is fixedly connected to a side support 2. The side support 2 enhances the stability of the processing table 1, resists the impact force during drilling and grinding, such as the cutting force of the drill bit 45, and avoids hole position offset due to overall equipment vibration, such as uneven drilling depth. Moreover, the side support 2 has an installation port, which makes it easy to fix it in the use position, further improving stability.

[0020] The drilling and grinding mechanism 4 includes an electric push rod 41 fixedly connected to the upper surface of the rear support plate 3. A connecting frame 42 is fixedly connected to the output end of the electric push rod 41. A rotary motor 43 is fixedly connected to the inner wall of the connecting frame 42. A grinding head 44 is fixedly connected to the output end of the rotary motor 43. A drill bit 45 is fixedly connected to the bottom end of the grinding head 44. The drilling and grinding mechanism 4 integrates the drill bit 45 and the grinding head 44. The drilling and grinding process can be completed in one feed driven by the electric push rod 41, avoiding the secondary clamping error of drilling first and then changing the grinding head 44 in the traditional method. The drill bit 45 first drills the basic hole, and then the grinding head 44 grinds the hole wall simultaneously. After one pass, the hole surface is burr-free, meeting the tightness requirements of the valve sealing surface. A diagonal brace 6 is fixedly connected to the outer surface of the rear support plate 3. The diagonal brace 6 is inclined and enhances the torsional resistance of the rear support plate 3. The strength is enhanced to resist the lateral force during the feed of the drilling and grinding mechanism 4. The guide assembly 5 includes a fixed ring 51 fixedly connected to the outer surface of the rear support plate 3. A sliding column 52 is slidably connected inside the fixed ring 51. A connecting plate 53 is fixedly connected to the bottom end of the sliding column 52. The outer surface of the connecting plate 53 is fixedly connected to the outer surface of the connecting frame 42. The sliding column 52 of the guide assembly 5 slides along the fixed ring 51, limiting the lifting trajectory of the connecting frame 42 and ensuring the vertical movement of the drilling and grinding tool. The drilling and grinding mechanism 4 integrates the drill bit 45 and the grinding head 44. Drilling and grinding can be completed in one feed, avoiding dimensional errors caused by secondary clamping. The sliding column 52 of the guide assembly 5 ensures the vertical lifting of the drilling and grinding tool, preventing hole diameter deviation or uneven hole wall caused by tilting, improving the surface finish of the mounting hole, and meeting the tightness requirements of valve sealing connection.

[0021] The working principle of this utility model is as follows: When machining flange valves, the valve body is first placed on the platform 11. Then, the electric cylinder 16 is started to drive the V-shaped clamping block 17 to clamp the body. At the same time, the sliding seat 14 moves along the main slide rod 13, so that the two V-shaped clamping blocks 17 clamp and position the workpiece. After the drilling and grinding mechanism 4 completes the drilling and grinding of the first hole, the drive motor 9 can be started to drive the sliding support cylinder 8 to rotate along the bottom ring slide rail 7. The positioned workpiece can be rotated, so that the next hole can be machined without disassembling the valve. The machining time for one hole is shortened compared with traditional equipment.
