Description

Technical Field

[0001] This utility model belongs to the field of composite reamer processing technology, and in particular relates to a segmented stepped composite reamer for double-eared holes. Background Technology

[0002] A stepped compound reamer typically consists of multiple teeth of different diameters, arranged in order of diameter on the cutting part of the tool. Each tooth has a specific cutting angle and cutting edge to effectively remove material during machining.

[0003] However, when processing double-eared holes, existing stepped reamers are subjected to multiple different cutting forces because both stepped cutting edges are in the reaming state at the same time. This can easily lead to unstable force on the reamer, resulting in one hole being qualified while the other is not. This greatly reduces the stability of hole diameter and hole wall quality. To address this, we propose a segmented stepped composite reamer for double-eared holes. Utility Model Content

[0004] The purpose of this invention is to provide a segmented stepped composite reamer for double-eared holes. By setting an inner rod, specifically a brake rod that drives a rotating block to rotate and move, the rotating block drives the inner rod to increase or decrease its extension length via a swivel ring. The inner rod drives the second tool to move upward or downward, thereby adjusting the distance between the first and second tools. By adjusting the distance between the two tools in the stepped design, the small hole can be machined first, followed by the main hole, which is more efficient and stable. It also facilitates the boring of double-eared holes of different depths. This invention solves the problem that when existing stepped reamers process double-eared holes, because the two stepped cutting edges are simultaneously in the reaming state, the reamer cutting edge is subjected to multiple different cutting forces at the same time, which easily leads to unstable force on the reamer, resulting in one hole being qualified while the other is not, greatly reducing the stability of hole diameter and hole wall quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a segmented stepped composite reamer for double-eared holes, including a shank, a reinforcing layer fixedly connected to the outer surface of the shank, and two actuation grooves formed on both the outer surface of the shank and the outer surface of the reinforcing layer.

[0007] A first cutting tool is fixedly connected to the bottom of the tool holder, and a second cutting tool is disposed below the first cutting tool. An inner rod is fixedly connected to the top of the second cutting tool, and four sliders are fixedly connected to the outer surface of the inner rod. A rotating ring is fixedly connected to the top of the inner rod, and a rotating groove is opened inside the rotating ring. A rotating block is rotatably connected inside the rotating groove, and a brake rod is fixedly connected to the top of the rotating block. A thread is fixedly connected to the outer surface of the brake rod, and a round block is fixedly connected to the top of the thread. The reinforcement layer can disperse these cutting forces, making the force more uniform and reducing the impact caused by the annular groove opened inside the tool holder.

[0008] Furthermore, a second sliding groove is provided on the inner side of the bottom of the tool holder, and the interior of the second sliding groove is slidably connected to the outer surface of the inner rod. Four limiting grooves are provided on the inner side of the bottom of the tool holder, and the interior of the limiting grooves is slidably connected to the outer surface of the slider. A first sliding groove is provided on the inner side of the top of the tool holder, and the interior of the first sliding groove is slidably connected to the outer surface of the circular block. By adjusting the distance between the two tools using the step, the small hole can be machined first, followed by the drilling, which is more efficient and stable, and also facilitates the boring work of double-eared holes of different depths.

[0009] Furthermore, an annular groove is provided inside the tool holder, and a torsion ring is rotatably connected inside the annular groove. The outer surface of the torsion ring is provided with anti-slip texture, and a circular hole is provided inside the torsion ring. A second thread is fixedly connected inside the circular hole, and the second thread is threadedly connected to the outer surface of the first thread. The anti-slip texture is provided to increase the friction with the fingers, thereby facilitating the adjustment of the extension length of the inner rod.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model, by setting an inner rod, specifically a brake rod that drives the rotating block to rotate and move, the rotating block drives the inner rod to increase or decrease the extension length through a rotating ring, and the inner rod drives the second tool to move up or down, thereby adjusting the distance between the first tool and the second tool. By adjusting the distance between the two tools through the step, the small hole is processed first, and then the drilling is processed, which is more efficient and stable, and also facilitates the boring work of double-ear plate holes of different depths.

[0012] 2. This utility model incorporates a reinforcing layer. Specifically, during the operation of the composite reamer, the shank needs to withstand cutting forces in multiple directions. When the tool cuts into the workpiece, the cutting force is transmitted to the shank through the cutting teeth. The reinforcing layer can disperse these cutting forces, making the stress more uniform and reducing the impact caused by the annular groove inside the shank.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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. 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 scope of protection of the present utility model.

[0024] Please see Figure 1-6 As shown, this utility model is a segmented stepped composite reamer for double ear holes, including a shank 1, a reinforcing layer 3 fixedly connected to the outer surface of the shank 1, and two actuation grooves opened on the outer surface of the shank 1 and the outer surface of the reinforcing layer 3.

[0025] A first cutter 4 is fixedly connected to the bottom of the tool holder 1. A second cutter 6 is set below the first cutter 4. An inner rod 5 is fixedly connected to the top of the second cutter 6. Four sliders 51 are fixedly connected to the outer surface of the inner rod 5. A rotating ring 52 is fixedly connected to the top of the inner rod 5. A rotating groove is opened inside the rotating ring 52. A rotating block 531 is rotatably connected inside the rotating groove. A brake rod 53 is fixedly connected to the top of the rotating block 531. A thread 54 is fixedly connected to the outer surface of the brake rod 53. A round block 55 is fixedly connected to the top of the thread 54. This utility model sets up a reinforcing layer 3. Specifically, during the operation of the composite reamer, the tool holder 1 needs to withstand cutting forces in multiple directions. When the cutter cuts into the workpiece, the cutting force will be transmitted to the tool holder through the cutter teeth. The reinforcing layer 3 can disperse these cutting forces, making the force more uniform and reducing the impact caused by the annular groove opened inside the tool holder 1.

[0026] The bottom inner side of the tool holder 1 is provided with a second sliding groove 13, which is slidably connected to the outer surface of the inner rod 5. The bottom inner side of the tool holder 1 is provided with four limiting grooves 12, which are slidably connected to the outer surface of the slider 51. The top inner side of the tool holder 1 is provided with a first sliding groove 11, which is slidably connected to the outer surface of the round block 55. This utility model sets the inner rod 5, specifically the brake rod 53 drives the rotating block 531 to rotate and move. The rotating block 531 drives the inner rod 5 to increase or decrease the extension length through the rotating ring 52. The inner rod 5 drives the second tool 6 to move up or down, thereby adjusting the distance between the first tool 4 and the second tool 6. By stepping the distance between the two tools, the small hole is processed first, and then the drilling is processed, which is more efficient and stable. It also facilitates the boring work of double ear holes of different depths.

[0027] The tool holder 1 has an annular groove inside, and a torsion ring 2 is rotatably connected inside the annular groove. The outer surface of the torsion ring 2 has anti-slip texture, and a round hole is opened inside the torsion ring 2. A threaded second 21 is fixedly connected inside the round hole, and the threaded second 21 is threadedly connected to the outer surface of the threaded first 54.

[0028] A specific application of this embodiment is as follows: First, install the reamer onto the equipment, ensuring it is stable and accurately positioned. Then, hold the torsion ring 2 and gently twist it to begin rotation. The torsion ring 2 has a thread 21 engraved on its inner circular hole. This thread 21 matches the thread 54. When the torsion ring 2 rotates, the engagement of the thread 21 and the thread 54 causes the thread 54 to begin rotating. The rotation of the thread 54 is not a simple rotation, but rather a downward or upward movement while rotating. Because the helix angle of the thread generates an axial thrust during rotation, the rotation and movement of the thread 54 further drive the brake lever 53 connected to it. Under the push of the thread 54, the brake lever 53 begins to rotate and simultaneously moves downward or upward. The distance of movement can be adjusted as needed. The movement of the brake lever 53, in turn, drives the rotation of its upper part. The moving block 531 not only rotates with the brake lever 53, but also moves under its influence. This movement is achieved through the rotating ring 52. The connection between the rotating ring 52 and the rotating block 531 allows the movement to be transmitted to the inner rod 5. Driven by the rotating block 531, the inner rod 5 begins to increase or decrease its extension length. This change in length directly determines the position of the second tool 6. The extension or retraction of the inner rod 5 causes the second tool 6 to move upward or downward. Through this adjustment mechanism, the distance between the first tool 4 and the second tool 6 can be easily adjusted. The adjustment of the distance is very important, as it determines the boring depth. For double-eared holes of different depths, the distance between the tools can be precisely adjusted by simply turning the torsion ring 2, thereby meeting different processing requirements. This design not only improves the flexibility of processing, but also greatly improves processing efficiency and accuracy.
