Description

Technical Field

[0001] This utility model relates to the field of valve processing equipment technology, and in particular to a five-way indexing chuck tooling. Background Technology

[0002] In the field of machining, the five-way connector is an important industrial component, widely used in fluid transmission, gas distribution, and complex mechanical systems due to its unique structural feature—five ports facing different directions. However, this special structure also brings machining challenges, especially when precisely machining each port of the five-way connector. Traditional machining methods have revealed many problems, seriously restricting production efficiency and product quality.

[0003] Traditionally, five-way connectors are machined by clamping one or a few ends in a single setup. Since a five-way connector has five ends in different directions, this means that multiple clamping operations are required to process all the ends. Each clamping operation consumes time for positioning, clamping, and adjustment. As the number of clamping operations increases, this process becomes not only time-consuming and labor-intensive but also significantly reduces overall processing efficiency. Furthermore, frequent clamping increases equipment wear and labor costs, leading to a significant increase in manufacturing costs.

[0004] More importantly, during the machining of bottom brackets, the position of the bottom bracket must be constantly changed to machine the nozzles in different directions. While this positional change seems simple, it actually poses a significant threat to machining accuracy. Because the relative positions of the bottom bracket's ends and nozzles easily change during these changes, deviations occur in the coaxiality of the machined bottom bracket's ends and the relative positional accuracy between the nozzles. These deviations not only affect the assembly performance and service life of the bottom bracket but can also adversely impact the entire system composed of bottom brackets, reducing the system's reliability and stability. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a five-way indexing chuck fixture. This design effectively solves the problem that the five-way pipe needs to be clamped and fixed multiple times during the pipe end processing, which affects the overall processing efficiency, processing accuracy, assembly performance and service life of the five-way pipe.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a five-way pipe body, an upper pressure block is fitted on the upper part of the five-way pipe body, and a lower support block is fitted on the lower part of the five-way pipe body. The upper pressure block and the lower support block are both provided with limiting components on their inner sides. The limiting components of the upper pressure block and the lower support block are engaged with each other to form a fixing cavity for fixing the five-way pipe body.

[0007] The limiting component includes a main pipe positioning block, a central branch pipe positioning block connected to one side of the main pipe positioning block, and a side branch pipe positioning block fixedly connected to the other side of the main pipe positioning block. The two ends of the central branch pipe positioning block are equidistant from the axis of the main pipe positioning block.

[0008] Preferably, the limiting component is fixedly connected to the upper pressure block or the lower support block by locking bolts.

[0009] Preferably, a first locking block is fixedly connected to the outer side of the upper pressing block, and a second locking block is fixedly connected to the outer side of the lower support block. A rotating table is fixedly connected to the first locking block and the second locking block, and a rotating groove is provided on the rotating table.

[0010] Preferably, the rotating platform is equipped with two sets of synchronously rotating adjustable blocks, and the two sets of adjustable blocks are fixedly connected to the first block and the second block by fixing bolts.

[0011] Preferably, the main pipe positioning block, the central branch pipe positioning block, and the side branch pipe positioning block are provided with arc-shaped grooves, and the radius of curvature of the grooves matches the radius of curvature of the five-way pipe body.

[0012] Preferably, the limiting component further includes an elastic buffer layer, which covers the inner contact surfaces of the main pipe positioning block, the central branch pipe positioning block, and the side branch pipe positioning block.

[0013] Compared with the prior art, the outstanding advantages of this utility model are:

[0014] This utility model uses an upper pressure block and a lower support block to fix the body of the bottom bracket, ensuring the stability of the bottom bracket body within the limiting component. The pipe opening of the bottom bracket body is exposed to the outside, and three pipe openings can be processed in one clamping, reducing the number of clamping times and improving processing efficiency.

[0015] This invention enables the processing of multiple pipe ends in a single clamping operation, effectively ensuring the coaxiality of the two ends and other related positional accuracy, thereby improving the overall processing precision and ensuring the stability of the five-way pipe body during use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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.

[0024] Please see the appendix Figure 1-6 This embodiment provides a five-way indexing chuck fixture, comprising a five-way pipe body 1, an upper pressure block 2 fitted above the five-way pipe body 1, and a lower support block 3 fitted below the five-way pipe body 1. Limiting components are provided on the inner sides of both the upper pressure block 2 and the lower support block 3. The limiting components of the upper pressure block 2 and the lower support block 3 engage with each other to form a fixing cavity for fixing the five-way pipe body 1. The limiting components include a main pipe positioning block 4, a central branch pipe positioning block 5 connected to one side of the main pipe positioning block 4, and a side branch pipe positioning block 6 fixedly connected to the other side of the main pipe positioning block 4. The two ends of the central branch pipe positioning block 5 are equidistant from the axis of the main pipe positioning block 4.

[0025] The five-way pipe body 1 consists of a main pipe and three branch pipes. The diameter of the main pipe is larger than the diameter of the branch pipes. Two of the three branch pipes are located on one side of the main pipe, and the third is located on the other side of the main pipe. The two branch pipes on the same side are symmetrically distributed about the midpoint of the main pipe. Each branch pipe is located on the vertical bisector of the main pipe. The upper pressure block 2 and the lower support block 3 are rectangular structures of the same specifications. The bottom surface of the upper pressure block 2 and the top surface of the lower support block 3 have the same component structure. The upper pressure block 2 and the lower support block 3 can be interlocked together. After they are interlocked, they form a fixing cavity to fix the five-way pipe body 1. The fixing cavity consists of two sets of main pipe positioning blocks 4, two sets of side branch pipe positioning blocks 6, and two sets of center branch pipe positioning blocks 5. The above six components The five-way pipe body 1 is fixedly positioned on the upper pressure block 2 and the lower support block 3 respectively. The two main pipe positioning blocks 4 are fastened to the upper and lower sides of the main pipe, the two side branch pipe positioning blocks 6 are fastened to the sides of the branch pipe with two branches on the same side, and the central branch pipe positioning block 5 is fastened to the sides of the branch pipe with only one branch on one side. This achieves the limitation of the five-way pipe body 1 and ensures the stability of the five-way pipe fixing. After the five-way pipe body 1 is fixed, the pipe openings of the two branch pipes on one side are processed separately. The two pipe openings of the main pipe and the pipe opening of the central branch pipe positioning block 5 can be processed sequentially after one clamping. In this way, when processing these three pipe openings, it is not necessary to open the clamping and fixing of the five-way pipe body 1 by the upper pressure block 2 and the lower support block 3, thereby improving the processing efficiency of the five-way pipe body 1.

[0026] The main pipe positioning block 4, the side branch pipe positioning block 6, and the central branch pipe positioning block 5 have fixing holes. The three are fixed to the upper pressure block 2 or the lower support block 3 by locking bolts 7. The detachable connection of the three can facilitate the replacement of components and facilitate subsequent maintenance. At the same time, when clamping different types of pipes, the pipes can be fixed by replacing the components, thus improving the applicability of the device.

[0027] The first locking block 8 is installed on the upper end of the upper pressure block 2, and the second locking block 9 is installed on the lower end of the lower support block 3. The first locking block 8 and the second locking block 9 are installed on the rotary table 10. The rotary table 10 is provided with a rotating groove 11 for placing the upper pressure block 2 and the lower support block 3. After the upper pressure block 2 and the lower support block 3 are fixed on the rotary table 10, the axis of the bottom pipe main body fixed by the main pipe positioning block 4 coincides with the center of the rotary table 10, ensuring that the main pipe of the bottom pipe body 1 rotates coaxially with the rotary table 10. Furthermore, to improve the processing of the bottom pipe body 1... To improve efficiency, an adjustable locking block 12 with a fixed angle is installed on the rotary table 10. The adjustable locking block 12 can rotate and be self-locked after adjustment. The adjustable locking block 12 can rotate 90 degrees each time. The rotary table 10 where the first locking block 8 and the second locking block 9 are located is connected to the adjustable locking block 12 by fixing bolts. After processing one pipe opening, the other pipe opening can be processed by rotating the adjustable locking block 12 90 degrees, reducing the disassembly and clamping process and improving the processing efficiency of the five-way pipe body 1.

[0028] The main pipe positioning block 4, the central branch pipe positioning block 5, and the side branch pipe positioning block 6 are all provided with grooves 13, and the arc radius of the grooves 13 in the three is different. The different grooves 13 correspond to different pipe diameters on the five-way pipe body 1, so that the main pipe positioning block 4, the central branch pipe positioning block 5, and the side branch pipe positioning block 6 can better limit the five-way pipe body 1.

[0029] Elastic buffer layers 14 are installed inside the main pipe positioning block 4, the central branch pipe positioning block 5, and the side branch pipe positioning block 6. The elastic buffer layer 14 has good deformation capacity and will undergo elastic deformation after being squeezed by the bottom pipe body 1. This allows for better contact with the curved surface of the bottom pipe body 1, increases the coefficient of friction between the bottom pipe body 1 and the bottom pipe body 1, improves the firmness of fixing the bottom pipe body 1, avoids shaking of the bottom pipe body 1 when processing the pipe end, and improves the accuracy of pipe end processing.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
