Description

Technical Field

[0001] The present invention relates to the field of honing, specifically to honing tools, and also to a honing device. Background Art

[0002] During the process of machining parts with a honing tool, honing fluid is usually used to flush the honing tool in a timely manner, and the iron filings and impurities honed off are taken away by the honing fluid in a timely manner. Moreover, the honing fluid also cools and lubricates the grinding head.

[0003] During the machining process, the honing tool is immersed in the honing fluid, and the honing fluid enters the inside of the base and cannot be discharged. There is a small gap (the gap is 0.03 - 0.05 mm) between the base and the tool body, making it difficult to discharge the honing fluid. In addition, the replacement cycle of the honing fluid is relatively long. During this period, the honing fluid is continuously recycled, which results in a large amount of impurities in the honing fluid. The impurities will precipitate and stay inside the base and cannot be discharged. The base will be subject to great resistance during expansion and contraction, and even cause a jamming phenomenon where it cannot shrink back after expanding, increasing the risk of unqualified cylinder bore roughness and crushing of the abrasive strips. Summary of the Invention

[0004] The purpose of the present invention is to overcome the problem that the honing fluid enters the inside of the honing tool and cannot be discharged in the prior art.

[0005] To achieve the above purpose, on the one hand, the present invention provides a honing tool, wherein the honing tool includes a base, a tool body that can be axially engaged with the base, and a tool expanding cone provided in the base. The first end of the tool expanding cone can be inserted into the tool body, and a drainage channel extending from the first end face to the second end face is provided in the tool expanding cone to allow the honing fluid entering between the base and the tool body to flow outwards.

[0006] In some embodiments, the drainage channel includes a plurality of branch channels arranged around the central axis of the tool expanding cone. The inlets of the plurality of branch channels are arranged around the central axis of the tool expanding cone on the first end face, and the outlets of the plurality of branch channels are located on the central axis of the tool expanding cone.

[0007] In some embodiments, the drainage channel includes a main channel arranged along the central axis of the tool expanding cone. The inlet of the main channel is communicated with the outlet of the branch channel, and the outlet of the main channel is arranged on the second end face.

[0027] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0028] Reference Figures 1 - 4 As shown, the present solution provides a honing tool, wherein the honing tool includes a base 1, a tool body 2 that can be axially engaged with the base 1, and a tool expanding cone 3 disposed in the base 1. The first end of the tool expanding cone 3 can be inserted into the tool body 2, and a drainage channel 4 extending from the end face of the first end to the end face of the second end is provided in the tool expanding cone 3 to allow the honing fluid entering between the base 1 and the tool body 2 to flow outwards.

[0029] The base 1 is the matrix of the honing head, and the above-mentioned hone bar can be provided thereon. The base 1 has a radially expandable structure, and a tapered surface is provided inside it. The tool expanding cone 3 cooperates with the tapered surface of the base 1. When the tool expanding cone 3 moves radially, it can act on the tapered surface of the base 1, causing the base 1 to expand radially, so that it can fit against the inner wall of the cylinder bore for grinding.

[0030] A circular groove for accommodating the tool expanding cone 3 is provided on the end face of the tool body 2 that is engaged with the base 1. The honing fluid entering the honing head from various gaps can reach the periphery of the first end of the tool expanding cone 3, that is, enter this circular groove.

[0031] The tool body 2 also forms a coaxial central hole to accommodate the following tool expanding rod 9 to pass through.

[0032] During the process of honing the cylinder bore with the honing tool, it is immersed in the honing fluid to achieve lubrication and cooling; the honing fluid enters the inside of the honing tool from various gaps of the honing tool. For example, between the tool expanding cone 3 and the base 1, between the base 1 and the tool body 2, and between the tool body 2 and the tool expanding rod 9.

[0033] A drainage channel 4 is provided in the tool expanding cone 3. The inlet of the drainage channel 4 is located on the end face of the first end of the tool expanding cone 3, that is, inside the honing tool, and its outlet is located on the end face of the second end of the tool expanding cone 3, and it extends out of the honing tool, so that the inside and outside of the honing tool can be communicated.

[0034] The honing fluid entering the inside through various gaps can reach the circular groove of the tool body 2 and can be discharged to the outside through the drainage channel 4, avoiding the accumulation of impurities in the honing fluid inside the honing tool, especially avoiding its entry into the base 1 and affecting the contraction movement of the base 1.

[0035] In this solution, the drainage channel can guide the honing fluid that enters the honing tool to the outside of the honing tool, reducing the accumulation of impurities inside, especially reducing the accumulation of impurities at the base, keeping the inside clean, enabling the base to expand and contract freely, and extending the service life.

[0036] In some embodiments of this solution, referring to Figure 1 and Figure 3 As shown, the drainage channel 4 includes a plurality of branch channels 6 arranged around the central axis of the tool expansion cone 3. The inlets of the plurality of branch channels 6 are arranged on the first end face around the central axis of the tool expansion cone 3, and the outlets of the plurality of branch channels 6 are located on the central axis of the tool expansion cone 3. The branch channels 6 form an angle with the central axis of the tool expansion cone 3, and their outlets are located on the central axis of the tool expansion cone 3. The first end face of the tool expansion cone 3 has a relatively large area, so a plurality of inlets can be arranged thereon, that is, a plurality of branch channels 6 are arranged. The inlets of the branch channels 6 are circumferentially spaced apart around its central axis. The inlets of the branch channels 6 are distributed at multiple positions, and the honing fluid can be guided into the drainage channel 4 at multiple positions.

[0037] Furthermore, in some embodiments, the drainage channel 4 includes a main channel 7 arranged along the central axis of the tool expansion cone 3. The inlet of the main channel 7 is communicated with the outlet of the branch channel 6, and the outlet of the main channel 7 is arranged on the second end face. The plurality of branch channels 6 converge into the main channel 7 to discharge the honing fluid through the main channel 7.

[0038] Among them, in some embodiments, the tool expansion cone 3 includes a first cone part at the first end and a second cone part at the second end, and the branch channels 6 are arranged in the first cone part. Referring to Figure 1 and Figure 3 As shown, the tool expansion cone 3 includes two cone parts, and the branch channels 6 are arranged in the first cone part at the first end. Therefore, it can be allowed to form an angle (about 12.5 degrees) with the central axis. The main channel 7 extends from the small end of the first cone part to the small end of the second cone part, so that the drainage channel 4 extends from the first end to the second end of the tool expansion cone 3.

[0039] In addition, in some embodiments, a liquid storage groove 5 is arranged on the first end face of the tool expansion cone 3, and the inlet of the drainage channel 4 is arranged in the liquid storage groove 5. The liquid storage groove 5 forms a space for accommodating the honing fluid between the first end face of the tool expansion cone 3 and the tool body 2, allowing the honing fluid to enter between the tool expansion cone 3 and the tool body 2, and then further enter the drainage channel 4 and be discharged to the outside. The inlet of the drainage channel 4 can be provided with a chamfer.

[0040] In some embodiments, a blind hole 8 is provided at the center of the end face of the first end of the expanding tool cone 3, and the honing tool includes an expanding tool rod 9 that can be inserted into the blind hole 8. The expanding tool rod 9 passes through the central hole of the tool body 2 and is inserted into the blind hole 8 to achieve docking of the expanding tool cone 3. When the expanding tool rod 9 moves towards the expanding tool cone 3, the expanding tool cone 3 can act radially outward on the base 1, causing the base 1 to expand radially. When the expanding tool rod 9 moves away from the expanding tool cone 3, the expanding tool cone 3 can be disengaged from the inner conical surface of the base 1 to allow the base 1 to contract. A spring 12 is provided on the base 1, and the spring 12 causes the base 1 to contract through its elastic force.

[0041] Among them, in some embodiments, the liquid storage tank 5 is an annular groove provided around the blind hole 8. Refer to Figure 2 and Figure 4 As shown, a ring-shaped flange is provided around the blind hole 8, so that the liquid storage tank 5 is formed as an annular groove surrounding the blind hole 8. The honing liquid can be accommodated in the liquid storage tank 5 and rarely enters the blind hole 8.

[0042] In addition, in some embodiments, a notch is provided on the outer periphery of the expanding tool rod 9, and the honing tool includes an anti-rotation pin 10 provided on the tool body 2 and mating with the notch. The anti-rotation pin 10 is radially inserted into the tool body 2 and abuts against the notch of the expanding tool rod 9, thereby restricting the rotation of the expanding tool rod 9.

[0043] During use, the honing liquid mainly enters the interior through the gap between the expanding tool rod 9 and the central hole of the tool body 2. Therefore, an inlet of the drainage channel 4 is provided on the end face of the expanding tool cone 3 facing the tool body 2, so that the honing liquid can be discharged, avoiding the honing liquid from entering the base 1.

[0044] In some embodiments, the honing tool further includes a honing strip 11 provided on the base 1. The honing strip 11 is the main structure for honing. The honing strips 11 are circumferentially spaced apart and can be disassembled.

[0045] In addition, the present solution also provides a honing device, and the honing device includes the honing tool according to any one of claims 1-9. The honing device includes components such as a motor, and the motor can drive the honing tool to rotate.
