Description

Technical Field

[0001] This utility model relates to the field of forged valve body technology, specifically a precision reaming device for processing forged valve bodies. Background Technology

[0002] Forged valve sleeve type drain valve has the advantages of reliable sealing, erosion resistance, long service life, high degree of standardization and generalization, excellent sulfur resistance and obvious energy saving effect. This valve is an ideal valve for venting parts of oil, natural gas, petrochemical and metallurgical and power systems where zero leakage and high service life are required. Therefore, precision reaming devices are often used in the machining of forged valve bodies.

[0003] The prior art discloses a precision reaming device for machining forged valve bodies (publication number: CN219025999U), which includes a base. A first motor is fixedly connected to the front right side of the top of the base. A bidirectional threaded rod is fixedly connected to the output end of the first motor. A belt is provided on the outer right side of the bidirectional threaded rod. Two connecting blocks are threadedly connected to the outer side of the bidirectional threaded rod. The adjacent sides of the two connecting blocks on the front and rear sides are fixedly connected to the outside of the clamping block. A spring is provided on the outside of the drill bit. A protective cover is fixedly connected to the bottom end of the spring. A water pump is fixedly connected to the top of the moving plate. A water tank is fixedly connected to the input end of the water pump. A hose is fixedly connected to the output pipe of the water pump.

Detailed Implementation

[0022] 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.

[0023] See also Figure 1-4 This utility model provides a technical solution:

[0024] Example 1:

[0025] A precision reaming device for machining forged valve bodies includes a worktable 1 and a support 2. Clamping mechanisms are provided on both sides of the support 2. The clamping mechanisms include a first telescopic cylinder 3, a clamping block 4, and a first sliding rod 5. The first telescopic cylinder 3 is located on both sides of the support 2, and its output end is fixedly connected to the outer center of the clamping block 4. The first sliding rod 5 is symmetrically arranged on both sides of the clamping block 4 and is slidably connected to the inside of the support 2. A reaming mechanism is provided on the upper part of the clamping mechanism, and a protective component 10 is provided on the outer side of the reaming mechanism for protection during the reaming process.

[0026] The hole reaming mechanism includes a second telescopic cylinder 6, a fixed plate 7, a servo motor 8, and a drill bit 9. The second telescopic cylinder 6 is located at the top center of the bracket 2, and the output end of the second telescopic rod is fixedly connected to the center of the fixed plate 7. The bottom of the fixed plate 7 is equipped with a servo motor 8, and the drill bit 9 is fixedly mounted on the shaft of the servo motor 8.

[0027] The protective assembly 10 includes a protective cover 101, a connecting plate 102, a second slide rod 103, and a spring 104. The protective cover 101 is located on the outer side of the bottom end of the drill bit 9, and the second slide rod 103 is provided on both sides of the protective cover 101 through the connecting plate 102. The second slide rod 103 is slidably connected to the inner sides of the fixing plate 7, and the spring 104 is sleeved on the outer side of the second slide rod 103. The protective assembly 10 also includes an annular pipe 105, a nozzle 106, and a connecting pipe 107. The annular pipe 105 is located on the inner side of the protective cover 101, and multiple nozzles 106 are equidistantly arranged on the inner side of the annular pipe 105. One side of the annular pipe 105 is connected to a water supply hose through the connecting pipe 107. The water supply hose is connected to a water tank through an external water pump.

[0028] By setting a protective component 10 on the outside of the hole-reaming mechanism, the device can cool down the hole and prevent impurities from splashing everywhere during the hole-reaming process of the valve body. The protective cover 101 on the outside of the bottom end of the drill bit 9 can protect the drill bit 9 during the working process, effectively preventing impurities from splashing everywhere during the drilling process and improving the safety of use. The annular pipe 105 and nozzles 106 on the inside of the protective cover 101 can spray water to the drill bit 9 from all directions to cool down and prevent dust, so that the drill bit 9 can be cooled during hole reaming, thereby not reducing the fatigue strength of the drill bit 9, thus increasing the service life of the drill bit 9 and improving the hole-reaming quality. In addition, the water spraying process of multiple nozzles 106 can wash away the impurities remaining on the inner wall of the protective cover 101, ensuring the protective effect of the protective cover 101.

[0029] A base 11 is provided at the center of the bottom of the clamping mechanism. An annular groove 12 is provided on the base 11. A collection component is provided at the bottom of the annular groove 12. The collection component includes a filter component 13, a water collection tank 14 and a water pump 15. The filter component 13 is located at the bottom of the annular groove 12, and the water collection tank 14 is located at the bottom of the filter component 13. A water pump 15 is provided on one side of the water collection tank 14. The water inlet of the water pump 15 is connected to the water collection tank 14 through a suction pipe, and the water outlet is connected to the water tank through an external pipe to realize water recycling.

[0030] The filter assembly 13 includes a conical cylinder 131, an external thread 132, a filter cylinder 134, an internal thread 135, and a conical filter screen 136. The conical cylinder 131 is disposed at the bottom of the annular groove 12 and is fixedly installed at the bottom of the workbench 1. The outer side of the bottom end of the conical cylinder 131 is provided with an external thread 132, which is threadedly connected to the internal thread 135 on the inner side of the top end of the filter cylinder 134. The conical filter screen 136 is disposed inside the filter cylinder 134.

[0031] The filter assembly 13 also includes a limiting ring 133, which is disposed on the upper part of the external thread 132.

[0032] In this embodiment, by setting up a base 11, an annular trough 12, and a collection component, the water sprayed from the protective component is collected and utilized in a unified manner, ensuring the cleanliness of the work site. The annular trough 12 on the workbench 1 allows the sprayed water to fall into the bottom filter component 13. The filter component 13 filters the enlarged-pore impurities in the water, and the filtered water falls into the water collection tank 14 for unified collection. The impurities are filtered and retained in the conical filter screen 136 in the filter component 13. The conical filter screen 136 achieves better filtration and collection, effectively prevents the filter screen from clogging easily, and improves the filtration effect. By disassembling the filter cylinder 134 at the bottom of the conical cylinder 131, the impurities filtered and collected in the conical filter screen 136 in the filter cylinder 134 can be cleaned, which facilitates the disassembly and assembly of the conical filter screen 136 and improves the convenience of work.

[0033] Working principle: First, the valve body placed on the base 11 is clamped and fixed using a clamping mechanism. The two first telescopic cylinders 3 on both sides of the bracket 2 are driven synchronously, causing the clamping blocks 4 on both sides to move closer together to clamp and fix the valve body, ensuring its stability. Then, the second telescopic cylinder 6 drives the servo motor 8, drill bit 9, and protective assembly 10 to move downwards. During this downward movement, the servo motor 8 drives the drill bit 9 to rotate. Simultaneously, the bottom surface of the protective cover 101 on the outer side of the bottom of the drill bit 9 first contacts the outer side of the hole to be enlarged in the valve body. As the rotating drill bit 9 moves downwards, it enlarges the valve body. During this enlargement process, the downward movement causes the fixing plate 7 to compress the spring 104 on the outer side of the second slide rod 103 at the bottom, ensuring the stable protection of the protective cover 101. The function is to effectively prevent impurities from splashing during the hole enlargement process. At the same time, it drives an external water pump to pump water from the water tank into the annular pipe 105 inside the protective cover 101, and sprays it onto the drill bit 9 through multiple nozzles 106, achieving the effect of cooling and dust prevention during the hole enlargement process. The sprayed water carries the impurities in the hole through the annular trough 12 and falls into the filter assembly 13 for solid-liquid filtration. The water collected in the water collection tank 14 can be pumped into the water tank by the water pump 15 for recycling. When a lot of impurities accumulate in the conical filter screen 136 in the filter assembly 13, the filter cylinder 134 can be directly rotated to remove it from the bottom of the conical cylinder 131. The impurities collected in the conical filter screen 136 in the filter cylinder 134 can be cleaned directly. After cleaning, the filter cylinder 134 can be reinstalled and reset for easy disassembly and cleaning.
