A valve body machining deburring tool

Abstract

This utility model relates to the field of deburring tools, specifically disclosing a deburring tool for valve body machining. It includes a deburring tool holder, a threaded cutter head mounted at one end of the holder, a threaded collar on the outer side of the threaded cutter head, an embedded threaded tube on the side surface of the threaded collar, a mounting screw inside the embedded threaded tube, an auxiliary guide rod below the threaded collar, an extension rod mounted on the upper surface of the mounting screw corresponding to the position of the auxiliary guide rod, an adjusting sleeve on the outer side of the extension rod and the auxiliary guide rod, and a rotating roller inside a roller lug. By rotating the adjusting sleeve to engage with the adjusting threads on the outer side of the auxiliary guide rod and the extension rod, the distance between the auxiliary guide rod and the blade is adjusted, allowing the rotating roller mounted on the roller lug to contact the side surface of the pipe. This provides rotational guidance during deburring, preventing the tool from failing to properly adhere to the side wall during rotation.

Description

Technical Field

[0001] This utility model relates to the field of deburring tools, specifically a deburring tool for valve body machining. Background Technology

[0002] A deburr maker houses a deburr in a clip, which in turn houses a handle. The clip has a connector profile shaped like a screwdriver head and can be inserted into the handle. The deburr can rotate within the head and can be replaced. Alternatively, a deburr can be held in place within the head.

[0003] However, after the valve body is machined, there will be burrs on both the inner and outer sides of the pipe end. When the cutting tool is deburring the pipe with a large diameter, the burr may be deviated during the machining of the mating side surface. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a deburring tool for valve body machining, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a deburring tool for machining valve bodies, including a deburring tool holder, a threaded cutting head installed at one end of the deburring tool holder, a threaded collar provided on the outer side of the threaded cutting head, an embedded threaded tube provided on the side surface of the threaded collar, a mounting screw provided inside the embedded threaded tube, an auxiliary guide rod provided below the threaded collar, an extension rod installed on the upper surface of the mounting screw corresponding to the position of the auxiliary guide rod, an adjusting sleeve provided on the outer side of the extension rod and the auxiliary guide rod, a roller lug installed at the end of the auxiliary guide rod away from the extension rod, and a rotating roller provided inside the roller lug.

[0006] As a further improvement of this utility model, the auxiliary guide rod and the extension rod are both provided with adjustable threads on their outer sides.

[0007] As a further improvement of this utility model: one end of the thread cutting head is provided with a blade that penetrates the interior of the deburring handle, and a blade change button is installed on the side surface of the deburring handle.

[0008] As a further improvement of this utility model, the threaded collar is engaged and fixedly connected with the thread cutting head.

[0009] As a further improvement of this utility model, a movable shaft is installed between the rotating roller and the roller lug.

[0010] As a further improvement of this utility model, the adjusting threads located on the outside of the extension rod and the auxiliary guide rod are arranged in opposite directions.

[0011] As a further improvement of this utility model, the auxiliary guide rod is an L-shaped structural component.

[0012] As a further improvement of this utility model: the blade change button is movably connected to the deburring handle, and the lower end of the blade change button is located inside the deburring handle and is fitted with a locking block that engages with the blade.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By rotating the adjusting sleeve to engage with the adjusting threads on the outside of the auxiliary guide rod and extension rod, the distance between the auxiliary guide rod and the blade is adjusted. This allows the rotating roller mounted on the roller ear plate to contact the side surface of the pipe, providing rotational guidance during deburring and preventing the blade from not adhering well to the side wall when rotating.

[0020] 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.

[0021] like Figure 1-4As shown, this embodiment provides a deburring tool for machining valve bodies, including a deburring tool holder 1. A threaded cutter head 2 is installed at one end of the deburring tool holder 1. A threaded collar 5 is provided on the outer side of the threaded cutter head 2. The threaded collar 5 is engaged and fixedly connected with the threaded cutter head 2. An embedded threaded tube 501 is provided on the side surface of the threaded collar 5. An installation screw 601 is provided inside the embedded threaded tube 501. An auxiliary guide rod 6 is provided below the threaded collar 5. The auxiliary guide rod 6 is an L-shaped structural component. An extension rod 605 is installed on the upper surface of the installation screw 601 at the position corresponding to the auxiliary guide rod 6. An adjustment sleeve 602 is provided on the outer side of the extension rod 605 and the auxiliary guide rod 6. A roller ear plate 603 is installed at the end of the auxiliary guide rod 6 away from the extension rod 605. A rotating roller 604 is provided inside the roller ear plate 603. A movable shaft is installed between the rotating roller 604 and the roller ear plate 603.

[0022] like Figure 2-3 As shown, in this embodiment, the auxiliary guide rod 6 and the extension rod 605 are both provided with adjustable threads 606 on their outer sides. The adjustable threads 606 on the outer sides of the extension rod 605 and the auxiliary guide rod 6 are arranged in opposite directions. One end of the thread cutter head 2 passes through the interior of the deburring handle 1 and is provided with a blade 3. A blade change button 4 is installed on the side surface of the deburring handle 1. The blade change button 4 is movably connected to the deburring handle 1. The lower end of the blade change button 4 is located inside the deburring handle 1 and is provided with a locking block that engages with the blade 3.

[0023] The working principle of this utility model is as follows: When deburring smaller holes on the valve body, the blade 3 at the end of the deburring handle 1 is inserted directly and scraped in a circular motion against the inner wall of the hole. When processing is required at the end of a pipe, the mounting screw 601 is fully engaged inside the embedded threaded tube 501. After the blade 3 is fully engaged outside the thread cutter head 2, the adjusting sleeve 602 is rotated according to the pipe wall thickness, and the adjusting thread 60 on the outside of the auxiliary guide rod 6 and the extension rod 605 is adjusted accordingly. 6. After adjusting the distance between the auxiliary guide rod 6 and the blade 3, the auxiliary guide rod 6 is placed on the outer wall of the pipe. This allows the rotating roller 604 mounted on the roller ear plate 603 to contact the side surface of the pipe. Then, the blade 3 is used to scrape the burrs by contacting the end side of the pipe. During the rotation, the rotating roller 604 is guided by the rotating shaft inside the roller ear plate 603, which can prevent the blade from not properly adhering to the side wall when rotating. Similarly, when scraping the burrs off the outer side of the pipe, the auxiliary guide rod 6 is inserted into the inner side of the pipe for adjustment.
