Description

Technical Field

[0001] This utility model relates to the field of honing head technology, and in particular to a honing head with replaceable honing bars. Background Technology

[0002] Honing is widely used in the field of mechanical manufacturing. It is often used to finish various precision holes to improve the dimensional accuracy, shape accuracy and surface quality of the holes. For example, the cylinder bore of automobile engine block and the inner bore of hydraulic cylinder need to be honing to ensure high-quality fit accuracy and surface performance.

[0003] After prolonged and high-frequency use, traditional honing heads suffer severe wear on the honing bars, leading to a decrease in machining accuracy. However, due to structural design issues, replacing the honing bars is extremely inconvenient, requiring a significant amount of time to disassemble, install, and debug the entire honing head system. This greatly impacts production progress and increases production costs. There is an urgent need for a honing head with easy-to-replace honing bars and a reasonable structural design to meet the demands of high-efficiency production.

[0004] Therefore, we propose a honing head with replaceable honing bars. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a honing head with replaceable honing bars.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A honing head with replaceable honing strips includes a honing head body. The surface of the honing head body is provided with a plurality of radial grooves. A honing strip is provided on the inner wall of the radial grooves. A guide strip is fixedly provided at the bottom end of the honing strip. The guide strip is parallel to the radial grooves. A protrusion is fixedly provided at one end of the guide strip. A guide slope is provided at the other end of the guide strip.

[0007] As a further improvement of this utility model: the guide strip is parallel to the honing strip, and a connecting block is fixedly provided between them, the width of the connecting block being the same as the width of the radial groove.

[0008] As a further improvement of this utility model: a sealing plate is movably provided on one side of the inner wall of the honing head body, and the sealing plate is connected to the main shaft of the honing equipment.

[0009] As a further embodiment of this utility model: the sealing plate is threadedly connected to the inner wall of the honing head body, a support spring is fixedly provided on the surface of the sealing plate, a support plate is fixedly provided at the top of the support spring, and the support plate is engaged with the inner wall of the honing head body.

[0010] As a further improvement of this utility model: the surface of the support plate is provided with a plurality of limiting grooves, which engage with the protrusions.

[0011] As a further embodiment of this utility model: an adjusting shaft is movably provided on the other side of the inner wall of the honing head body, the surface of the adjusting shaft is threadedly connected to the inner wall of the honing head body, and an adjusting cone surface is engaged at the top end of the adjusting shaft.

[0012] As a further improvement of this utility model: the adjusting cone surface is conical, and a number of adjusting slots are provided on the surface. The number of adjusting slots is the same as the number of honing strips, and they are in contact with the guide slope.

[0013] Compared with the prior art, the present invention provides a honing head with replaceable honing bars, which has the following advantages: This invention allows for easy replacement of honing strips. Simply loosen the adjusting shaft to lower the adjusting cone, and the honing strip will retract along the radial groove under its own weight or auxiliary external force. Since the guide strip and connecting block fix the honing strip, and the width of the connecting block is the same as the width of the radial groove, the honing strip retracts stably. Then, through the cooperation of the protrusion and the limiting groove, the worn honing strip can be easily pulled out of the radial groove. A new honing strip can then be inserted, and the adjusting shaft can be readjusted so that the adjusting cone pushes the guide slope, allowing the honing strip to extend to the appropriate position for continued operation. This greatly shortens the honing strip replacement time and improves production efficiency.

[0014] This invention features a movably mounted sealing plate on one side of the inner wall of the honing head body. The sealing plate is connected to the main shaft of the honing equipment and engages with the inner wall of the honing head body via a support spring and a support plate. This design not only ensures the overall stability of the honing head during high-speed rotation but also effectively buffers vibrations and impacts during processing, reducing damage to the honing strips and workpieces. An adjusting shaft on the other side is threaded to the inner wall of the honing head body. The adjusting cone at the top of the adjusting shaft precisely matches the guide slope of the honing strips, enabling precise and stable adjustment of the honing strip extension length. This ensures that the extension length of each honing strip is consistent, resulting in uniform grinding of the workpiece's inner hole during honing and effectively improving processing accuracy.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0020] Example: A honing head with replaceable honing bars, such as Figures 1-4 As shown, the honing head body 1 is provided with a plurality of radial grooves 2 on its surface. A honing strip 3 is provided on the inner wall of the radial groove 2. A guide strip 4 is fixedly provided at the bottom end of the honing strip 3. The guide strip 4 is parallel to the radial groove 2. A protrusion 5 is fixedly provided at one end of the guide strip 4. A guide slope is provided at the other end of the guide strip 4. The guide strip 4 is parallel to the honing strip 3 and a connecting block 6 is fixedly provided between them. The width of the connecting block 6 is the same as the width of the radial groove 2.

[0021] like Figures 1-4 As shown, a sealing plate 7 is movably installed on one side of the inner wall of the honing head body 1. The sealing plate 7 is connected to the main shaft of the honing equipment and is threadedly connected to the inner wall of the honing head body 1. A support spring 8 is fixedly installed on the surface of the sealing plate 7, and a support plate 9 is fixedly installed on the top of the support spring 8. The support plate 9 is engaged with the inner wall of the honing head body 1. The sealing plate 7 is movably installed on one side of the inner wall of the honing head body 1 and is connected to the main shaft of the honing equipment. At the same time, it is engaged with the inner wall of the honing head body 1 through the support spring 8 and the support plate 9. This design not only ensures the overall stability of the honing head when rotating at high speed, but also effectively buffers the vibration and impact during the processing, reducing damage to the honing strip 3 and the workpiece.

[0022] like Figures 1-3 As shown, the surface of the support plate 9 is provided with several limiting grooves 10, which engage with the protrusions 5. An adjusting shaft 11 is movably provided on the other side of the inner wall of the honing head body 1. The surface of the adjusting shaft 11 is threadedly connected to the inner wall of the honing head body 1. An adjusting cone surface 12 is engaged at the top of the adjusting shaft 11. The adjusting cone surface 12 is conical and has several adjusting slots 13 on its surface. The number of adjusting slots 13 is the same as the number of honing strips 3 and they are in contact with the guide slope. The adjusting shaft 11 is threadedly connected to the inner wall of the honing head body 1. The adjusting cone surface 12 at the top of the adjusting shaft 11 is precisely matched with the guide slope of the honing strips 3. When adjusting the extension length of the honing strips 3, fine and stable adjustment can be achieved to ensure that the extension length of each honing strip 3 is consistent. Thus, the inner hole of the workpiece is uniformly ground during the honing process, which effectively improves the processing accuracy, ensures the dimensional accuracy, shape accuracy and surface quality of the inner hole of the workpiece, and meets the stringent requirements for the processing of high-precision parts.

[0023] Working principle: The honing head body 1 is connected to the main shaft of the honing equipment, which drives the honing head body 1 to rotate at high speed. When honing the inner hole of the workpiece is required, the adjusting shaft 11 rotates, and its surface is threaded into the inner wall of the honing head body 1, causing the adjusting cone surface 12 at the top of the adjusting shaft 11 to move upward. Since the adjusting cone surface 12 is conical and has adjusting slots 13 with the same number as the honing strips 3, these adjusting slots 13 are in contact with the guide slope at one end of the guide bar 4. As the adjusting cone surface 12 rises, the adjusting slots 13 push the guide slope, thereby causing the guide bar 4 to drive the honing strips 3 to extend outward along the radial groove 2. The honing strips 3 contact and perform grinding on the inner hole of the workpiece. Meanwhile, the sealing plate 7 is connected to the main shaft of the honing equipment. The sealing plate 7 supports the inner wall of the honing head body 1 through the support spring 8 and the support plate 9. The limiting groove 10 on the support plate 9 engages with the protrusion 5 at one end of the guide strip 4 to ensure the stability and accuracy of the honing strip 3 during the extension and retraction process, and to prevent the honing strip 3 from shaking or deviating.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
