Description

Technical Field

[0001] This utility model relates to the field of reamer technology, and in particular to a nano-coated high wear-resistant reamer. Background Technology

[0002] In the field of machining, reamers are a commonly used hole-making tool, mainly used to finish machined holes to improve their dimensional accuracy, shape accuracy and surface roughness. They are widely used in precision manufacturing industries such as automobile manufacturing, aerospace, and mold processing.

[0003] Most existing reamers are fixed structures with non-adjustable dimensions, which presents the following problems in actual operation:

[0004] 1) When assembling with the cutter head, since the depth of the cutter head groove varies with different cutter heads, in order to ensure the installation stability and machining accuracy of the reamer, it is often necessary to equip the cutter head grooves of different depths with adapters of different lengths.

[0005] 2) During reaming, the reamer generates a large amount of metal chips. If there is no effective obstruction, these chips can easily strike the end where the reamer is connected to the cutter head. Utility Model Content

[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide a nano-coated high wear-resistant reamer to solve the technical problems of the current reamer and cutter head assembly, which require different length adapters due to different cutter head groove depths, and the direct impact of metal chips on the connection end between the reamer and cutter head during reaming due to the lack of effective obstruction.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A nano-coated high wear-resistant reamer includes a head post and a reamer shank. A reamer head is installed at the end of the head post away from the reamer shank. A reinforcing sleeve driven by a first threaded shaft is movably connected between the reamer shank and the reamer head and located in the head post.

[0010] The end of the reamer handle extending into the cutter head post is fixedly connected to the reinforcing sleeve. The reinforcing sleeve is threadedly connected to the end of the first threaded shaft extending into the cutter head post. The end of the reamer handle protruding from the cutter head post is provided with an assembly angle groove that matches the cutter head seat.

[0011] As an improved technical solution, the end of the cutter head column near the reamer head is rotatably connected to an adjusting nut, and the end of the first threaded shaft away from the reinforcing sleeve is fixedly connected to the adjusting nut. The first threaded shaft is rotatably connected to the cutter head column through the adjusting nut, and a second threaded shaft is fixedly installed at the end of the adjusting nut away from the first threaded shaft.

[0012] As an improved technical solution, a threaded sleeve driven by a second threaded shaft is provided between the reamer head and the reamer head column, and an anti-wear cover is fixedly installed on the threaded sleeve. The anti-wear cover has a threaded opening at one end near the threaded sleeve. The anti-wear cover is threadedly connected to the end of the second threaded shaft away from the adjusting nut through the threaded opening, and the anti-wear cover is sleeved outside the reamer head.

[0013] As an improved technical solution, a reinforcing rotating rod is fixedly installed at the end of the second threaded shaft away from the adjusting nut, and one end of the reinforcing rotating rod extends into the reamer head. The reamer head is rotatably connected to the second threaded shaft through the reinforcing rotating rod.

[0014] As an improved technical solution, the inner side of the wear-resistant cover is fixedly installed with guide groove protrusions, and the guide groove protrusions are distributed in a ring array around the reinforcing rotating rod. The reamer head is provided with a guide groove for limiting the movement of the guide groove protrusions.

[0015] As an improved technical solution, the anti-wear cover is interference-fitted with the reamer head, and the anti-wear cover is also provided with a chip discharge groove for discharging waste chips from the reamer head.

[0016] As an improved technical solution, the reamer head has a ring-shaped array of chip-removing ridges on its circumferential surface, and the chip-removing ridges are inclinedly arranged on the reamer head around the rotation axis of the reamer head.

[0017] As an improved technical solution, both the reamer shank and the reamer tip are covered with a wear-resistant nano-coating.

[0018] After adopting the above technical solution, the beneficial effects of this utility model are:

[0019] 1. This utility model uses a rotating adjusting nut to drive the first threaded shaft to rotate, thereby enabling the reinforcing sleeve to drive the reamer handle to adjust the length of the extended or retracted cutter head column. Combined with the precise fit between the assembly angle groove and the cutter head seat, it can adapt to cutter head grooves of different depths without the need to change different length adapters, thus improving the adaptability and convenience of reamer and cutter head assembly.

[0020] 2. In this utility model, by adjusting the nut to drive the second threaded shaft to rotate, the wear-resistant cover moves stably along the axial direction under the cooperation of the guide groove protrusion and the guide slide and is interference-fitted with the reamer head. At the same time, the chip removal ridge guides the waste chips to the chip removal groove for discharge, effectively blocking the waste chips.

[0021] 3. This utility model strengthens the connection between the second threaded shaft and the reamer head by setting a reinforcing rotating rod and avoids motion interference. At the same time, a wear-resistant nano-coating is set on the reamer handle and the reamer head to reduce the wear rate during use. Attached Figure Description

Detailed Implementation

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0032] like Figures 1 to 6 As shown in the figure, this embodiment provides a nano-coated high wear-resistant reamer. This nano-coated high wear-resistant reamer includes a head post 1 and a reamer shank 2. A reamer head 3 is installed at the end of the head post 1 away from the reamer shank 2. A reinforcing sleeve 4, driven by a first threaded shaft 501, is movably connected between the reamer shank 2 and the reamer head 3 and located in the head post 1. One end of the reamer shank 2 extending into the head post 1 is fixedly connected to the reinforcing sleeve 4. The reinforcing sleeve 4 is threadedly connected to one end of the first threaded shaft 501 extending into the head post 1. The end of the reamer shank 2 protruding from the head post 1 is provided with an assembly groove 201 adapted to the cutter head seat. The head post 1 serves as the main support structure of the reamer, providing support for all components. The installation provides a stable bearing base. The reamer head 3 is the core working component for hole machining, directly contacting the workpiece to perform reaming operations. The reinforcing sleeve 4 is completely located in the reamer head column 1, which can enhance the structural strength of the connection between the reamer shank 2 and the reamer head column 1, and prevent deformation or damage due to excessive force during machining. When the first threaded shaft 501 rotates, it can drive the reinforcing sleeve 4 to move axially within the reamer head column 1, thereby realizing the length adjustment of the reamer shank 2 extending or retracting from the reamer head column 1. The mounting angle groove 201 can precisely match the corresponding structure on the cutter head seat, ensuring the stability and accuracy of the reamer installation on the cutter head, and preventing loosening or displacement during machining.

[0033] The end of the cutter head column 1 near the reamer head 3 is rotatably connected to an adjusting nut 5, and the end of the first threaded shaft 501 away from the reinforcing sleeve 4 is fixedly connected to the adjusting nut 5. The first threaded shaft 501 is rotatably connected to the cutter head column 1 through the adjusting nut 5. The end of the adjusting nut 5 away from the first threaded shaft 501 is fixedly installed with a second threaded shaft 502. The rotational motion of the adjusting nut 5 can be directly transmitted to the first threaded shaft 501, so that the first threaded shaft 501 rotates synchronously, so that the first threaded shaft 501 can rotate flexibly and its position on the cutter head column 1 is relatively stable. The second threaded shaft 502 can rotate synchronously with the first threaded shaft 501 through the adjusting nut 5.

[0034] A threaded sleeve 7 driven by a second threaded shaft 502 is provided between the reamer head 3 and the cutter head column 1. An anti-wear cover 8 is fixedly installed on the threaded sleeve 7. The anti-wear cover 8 has a threaded opening 801 at one end near the threaded sleeve 7. The anti-wear cover 8 is threadedly connected to the end of the second threaded shaft 502 away from the adjusting nut 5 through the threaded opening 801. The anti-wear cover 8 is sleeved on the outside of the reamer head 3. The anti-wear cover 8 is made of high wear-resistant material and can effectively protect the reamer head 3 and the connection end between the reamer and the cutter head seat. It is threadedly connected to the second threaded shaft 502 through the threaded opening 801. When the second threaded shaft 502 rotates, it can drive the anti-wear cover 8 to move axially to adjust the position of the cover. The anti-wear cover 8 is sleeved on the outside of the reamer head 3 and can cover most of the reamer head 3 to block the waste chips generated during the machining process.

[0035] A reinforcing rod 6 is fixedly installed at the end of the second threaded shaft 502 away from the adjusting nut 5, and one end of the reinforcing rod 6 extends into the reamer head 3. The reamer head 3 is rotatably connected to the second threaded shaft 502 through the reinforcing rod 6. The reinforcing rod 6 can enhance the structural strength of the connection between the second threaded shaft 502 and the reamer head 3, and avoid damage due to concentrated force. When the reamer head 3 is not rotating, the second threaded shaft 502 can rotate on it through the reinforcing rod 6, thereby avoiding motion interference with the rotation of the adjusting nut 5.

[0036] The inner side of the wear-resistant cover 8 is fixedly installed with guide groove protrusions 802, and the guide groove protrusions 802 are arranged in a ring array around the reinforcing rotating rod 6. The reamer head 3 is provided with a guide groove 301 for limiting the movement of the guide groove protrusions 802. The guide groove protrusions 802 and the guide groove 301 cooperate with each other to guide and limit the movement of the wear-resistant cover 8, ensuring that the wear-resistant cover 8 can move stably and accurately along the axial direction, and preventing it from deviating or shaking during the movement.

[0037] The anti-wear cover 8 is interference-fitted with the reamer head 3. The anti-wear cover 8 is also provided with a chip discharge groove 803 for discharging the waste chips on the reamer head 3. The anti-wear cover 8 can achieve a tight connection with the reamer head 3 through the interference fit, reducing the gap between the two and further enhancing the blocking effect on waste chips. The chip discharge groove 803 can discharge the waste chips blocked by the cover in a timely manner, preventing the waste chips from accumulating in the cover and affecting the normal operation of the reamer.

[0038] The reamer head 3 has a ring array of chip-removing ridges 302 on its circumferential surface. The chip-removing ridges 302 are inclined around the rotation axis of the reamer head 3. During the rotation of the reamer head 3, the chip-removing ridges 302 can guide the waste chips generated by reaming along the inclined direction to the chip removal groove 803, which facilitates the discharge of waste chips. At the same time, it can also enhance the cutting performance and structural strength of the reamer head 3.

[0039] Both the reamer handle 2 and the reamer head 3 are covered with a wear-resistant nano-coating. The nano-coating has extremely high hardness and excellent wear resistance, which can significantly reduce the wear rate of the reamer handle 2 and the reamer head 3 during use and extend the service life of the reamer.

[0040] When using this reamer to process an object, during the assembly stage with the cutter head, the rotation of the adjusting nut 5 is synchronously transmitted to the first threaded shaft 501 by rotating it. Since the reinforcing sleeve 4 is threadedly engaged with the first threaded shaft 501 and is completely located in the cutter head column 1, the rotation of the first threaded shaft 501 will drive the reinforcing sleeve 4 to move axially within the cutter head column 1. The reamer handle 2 is fixedly connected to the reinforcing sleeve 4, thereby realizing the length adjustment of the reamer handle 2 extending or retracting from the cutter head column 1. After adjusting to the appropriate length, the mounting angle groove 201 at the protruding end of the reamer handle 2 is precisely engaged with the corresponding structure of the cutter head seat, ensuring the stability and accuracy of the installation. It can adapt to cutter head grooves of different depths without the need to replace different length adapters.

[0041] During the process, the rotation of the adjusting nut 5 drives the second threaded shaft 502 to rotate synchronously. Because the anti-wear cover 8 is threadedly engaged with the second threaded shaft 502 through the threaded opening 801, and the guide groove protrusion 802 on its inner side is limited to move within the guide groove 301 of the reamer head 3, the rotation of the second threaded shaft 502 will drive the anti-wear cover 8 to move stably along the axial direction, so that it is fitted on the outside of the reamer head 3 and tightly connected by interference fit, effectively blocking the waste chips generated during processing, and will not affect the parts in contact with the workpiece. At the same time, when the annular array of inclined chip-removing ridges 302 on the circumference of the reamer head 3 rotates, it guides the waste chips along the inclined direction to the chip removal groove 803 on the anti-wear cover 8 for discharge, preventing the accumulation of waste chips.

[0042] The reinforcing rod 6 enhances the strength of the connection between the second threaded shaft 502 and the reamer head 3. When the reamer head 3 is not rotating, the second threaded shaft 502 can rotate on it via the reinforcing rod 6, avoiding motion interference with the rotation of the adjusting nut 5. The wear-resistant nano-coating on the reamer handle 2 and the reamer head 3, with its high hardness and excellent wear resistance, reduces the wear rate during use and extends the service life of the reamer.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
