Description

Technical Field

[0001] This invention belongs to the field of fire hydrant technology. Specifically, this invention relates to an integrated device for machining fire hydrant threaded holes. Background Technology

[0002] A fire hydrant is a fixed fire-fighting facility, usually placed around places where people gather. Fire hydrants are connected to the local water supply facilities and can quickly deliver water to extinguish fires using hoses, nozzles, etc.

[0003] A patent application (patent number 202223198143.7, published on March 21, 2023) discloses a device for machining threaded holes in above-ground fire hydrants. The device includes a base, a base for holding the fire hydrant, a drill bit, and a thread tap. The base is movably mounted on the base, and a clamping mechanism is provided on the base to clamp the fire hydrant. The drill bit is mounted on the base to drill holes in the fire hydrant. The thread tap is mounted on the base, located to one side of the drill bit, and arranged side-by-side with the drill bit to machine the threads in the holes of the fire hydrant. This invention improves machining efficiency by using a drill bit and a thread tap, and the clamping mechanism automatically clamps the fire hydrant, eliminating the need for manual clamping.

[0004] During the manufacturing process of fire hydrants, threaded holes need to be machined into the hydrant body to install fire-fighting equipment such as hoses and nozzles. However, because the fire hydrant body is large and heavy, it is very inconvenient and inefficient to transport it to the thread processing machine after grinding and polishing the inner wall of the hole. Summary of the Invention

[0005] The present invention aims to provide an integrated device for machining fire hydrant threaded holes, which facilitates the machining of threaded holes.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an integrated device for machining fire hydrant threaded holes, comprising a housing, a clamping device for clamping fire hydrants on the housing, a dual-station boring machine located above the fire hydrants on the housing, and a dual-station boring tool at the bottom of the boring machine, the boring tool being divided into a round hole tool and a threading tool.

[0007] The clamping device includes a sliding seat mounted on the machine housing, and a fixing ring is provided on the sliding seat.

[0008] The sliding seat is provided with a ring seat to support the fire hydrant, and the fixing ring is set on the ring seat.

[0009] The housing is provided with a slide rail, the sliding seat is mounted on the slide rail, and the sliding seat is provided with fixing bolts.

[0010] There are two boring tools, which are arranged side by side.

[0011] The output end of the boring machine is equipped with a clamping block, and the boring tool is clamped on the clamping block by screws.

[0012] The technical advantages of this invention are as follows: by using a dual-station boring tool, the hole is first drilled with the boring tool, and then the clamping device is moved to move the machined fire hydrant under another boring tool. The second boring tool is used to bore the thread into the machined hole. The two functions of boring and threading are completed on the same machine. By reducing the running time between the two stations and integrating the two stations together, the processing efficiency of fire hydrant holes can be effectively improved.

[0016] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0017] Please see Figure 1 An integrated device for machining fire hydrant threaded holes includes a housing 1, a clamping device for clamping fire hydrants 2 on the housing 1, and a dual-station boring machine 3 located above the fire hydrant 2 on the housing 1. The bottom end of the boring machine 3 is equipped with a dual-station boring tool 4, which is divided into a round hole tool 41 and a thread tool 42. Using the dual-station boring tool 4, a hole is first drilled with the boring tool 4, and then the clamping device is moved to move the machined fire hydrant 2 below the other boring tool 4. The second boring tool 4 is used to bore the threaded line into the machined hole. The two functions of boring and threading are completed on the same machine. By reducing the running time between the two stations and integrating the two stations together, the machining efficiency of the fire hydrant 2 hole can be effectively improved. It can realize the function of machining threads in the hole after machining and polishing the hole.

[0018] The clamping device includes a sliding seat 5 mounted on the housing 1, and a fixing ring 6 is provided on the sliding seat 5; the fire hydrant 2 is fixed by the positioning ring, and the sliding seat 5 can move the fixed fire hydrant 2 so that the fire hydrant 2 can be moved from one station to the next station.

[0019] The sliding seat 5 is provided with a ring seat 7 to support the fire hydrant 2, and a fixing ring 6 is set on the ring seat 7; the fire hydrant 2 is placed on the ring seat 7 and positioned by the ring seat 7, which facilitates the subsequent fixing of the fixing ring 6.

[0020] The housing 1 is provided with a slide rail 8, and the sliding seat 5 is set on the slide rail 8. The sliding seat 5 is provided with a fixing bolt 9. The sliding seat 5 can slide left and right along the slide rail 8 to move the fire hydrant 2. When it moves to the bottom of the boring tool 4, the sliding seat 5 is fixed by the fixing bolt 9 to prevent it from shifting during processing.

[0021] There are two boring tools 4, which are arranged side by side; this makes it easy to move the fire hydrant 2 to below the boring tools 4.

[0022] The output end of the boring machine 3 is equipped with a clamping block 10, and the boring tool 4 is clamped on the clamping block 10 by screws; this facilitates the disassembly and replacement of the tool.

[0023] The technical effect of this invention is as follows: by using a dual-station boring tool 4, the hole is first opened with the boring tool 4, and then the clamping device is moved to move the processed fire hydrant 2 to the bottom of another boring tool 4. The second boring tool 4 is used to bore the thread line of the processed hole. The two functions of boring and threading are completed on the same machine. By reducing the running time between the stations and integrating the two stations together, the processing efficiency of the fire hydrant 2 hole can be effectively improved.

[0024] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
