Abstract
Description
Technical Field
[0001] This utility model relates to the field of honing rods, and in particular to a flutter-resistant honing rod damping and vibration reduction kit. Background Technology
[0002] Honing is a high-efficiency machining method that enables workpieces to achieve high precision, high surface quality, and long service life. It can effectively improve dimensional accuracy, shape accuracy, and reduce Ra value, but it cannot improve the positional accuracy of holes and other surfaces. It can be used to machine cast iron parts, hardened and unhardened steel parts, and bronze parts, but it is not suitable for machining tough non-ferrous metal parts. In machining, honing is a high-precision internal hole machining method, widely used in the automotive, aerospace, and other fields. During the honing process, a large amount of heat and vibration are generated between the honing rod and the workpiece. If these vibrations are not suppressed, they will cause chatter between the honing rod and the workpiece, affecting machining accuracy and surface quality.
[0003] Traditional vibration reduction methods often employ straight-through cooling channels or simple spring vibration damping devices, which have limited vibration reduction effects and are difficult to meet the requirements of high-precision honing.
[0004] Therefore, it is necessary to propose a honing rod damping and vibration reduction kit to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a damping and vibration reduction kit for honing rods to solve the problem that traditional vibration reduction methods often use straight-through cooling channels or simple spring vibration reduction devices, which have limited vibration reduction effects and are difficult to meet the requirements of high-precision honing.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a flutter-resistant honing rod damping and vibration reduction kit, comprising:
[0007] Honing head;
[0008] A honing rod, the bottom end of which is connected to an extrusion head, the extrusion head being movably installed inside the honing head;
[0009] The honing head is equipped with a buffer at its bottom interior to reduce vibration of the extrusion head;
[0010] The honing head is provided with a lubricating oil inlet, and the buffer is also used to push the lubricating oil upward.
[0011] Preferably, the honing head has an internal cavity, and the buffer is installed at the bottom of the internal cavity;
[0012] The buffer includes a damper and a second spring. The second spring is sleeved on the outside of the damper. A buffer plate is fixed at the top of the buffer. A sealing gasket is provided on the outside of the buffer plate. The sealing gasket is movably fitted against the inner wall of the cavity.
[0013] Preferably, there are insert blocks telescopically connected to both sides of the inner cavity, one end of the insert block extends out of the honing head, and a fixed end is connected to the outside of the extended end;
[0014] One end of the fixed end is provided with a snap-fit groove, and an oilstone is installed inside the snap-fit groove.
[0015] Preferably, the honing head has a protective sleeve at its top, the lubricating oil inlet is located on the outside of the protective sleeve, and the outer sleeve of the protective sleeve is located on the outside.
[0016] Preferably, a first spring is sleeved on the outer side of the honing rod.
[0017] Preferably, the fixed end is provided in multiple ways to extend and retract around the honing head, and each honing head has a groove at its top, with an elastic ring installed between the grooves.
[0018] The technical effects and advantages of this utility model are as follows:
[0019] 1. In the actual operation of this utility model, when the extrusion head moves downward, it will squeeze the buffer plate and the buffer component, thereby using the elasticity of the buffer component to push the extrusion head back to its original position. The buffer component can also buffer the vibration of the extrusion head, making the up-and-down movement of the extrusion head more stable.
[0020] 2. Furthermore, when lubricating oil is introduced into the inner cavity, the elastic force of the buffer can push the lubricating oil upward, allowing it to rise to a higher position to lubricate the extrusion head and honing rod. This not only provides lubrication and cooling but also enhances the vibration reduction effect. By effectively controlling the vibration during the honing process, it reduces the processing errors caused by chatter, thereby improving the surface quality and processing efficiency.
[0021] 3. The design of multiple fixed ends and elastic rings further enhances the stability and reliability of the structure, and can help the multiple protruding fixed ends to reset and retract. Attached Figure Description

[0026] This utility model provides, for example Figs. 1-3 The illustrated anti-flutter honing rod damping vibration reduction kit includes:
[0027] like Fig. 3 As shown, there is a honing head 3, a honing rod 1, and a pressing head 15 connected to the bottom end of the honing rod 1. The pressing head 15 is movably installed inside the honing head 3. The honing head 3 has an inner cavity 14. In the actual operation of this utility model, the honing rod 1 is connected to a driving device. The driving device can drive the honing rod 1 and the pressing head 15 to move up and down and rotate inside the inner cavity 14.
[0028] The inner cavity 14 has two telescopically connected fitting blocks 12 on both sides. One end of the fitting block 12 extends out of the honing head 3, and a fixed end 4 is connected to the outside of the extended end. The fixed end 4 has a snap-fit groove 5 at one end, and an oilstone 8 is installed inside the snap-fit groove 5. The snap-fit groove 5 is used to install the oilstone 8.
[0029] When the extrusion head 15 moves up and down, the outer side of the extrusion head 15 will press against the outer side of the fitting block 12, causing the fitting block 12 to drive the fixed end 4 to extend away from the honing head 3, thereby causing the oilstone 8 to rub against the outer side of the workpiece.
[0030] To address the issue that traditional vibration reduction methods often employ straight-through cooling channels or simple spring vibration damping devices, which have limited vibration reduction effects and are difficult to meet the requirements of high-precision honing, a buffer 13 is provided at the bottom of the honing head 3 to reduce the vibration of the extrusion head 15. The honing head 3 is also provided with a lubricating oil inlet 7. The buffer 13 is also used to push the lubricating oil upward. The buffer 13 is installed at the bottom of the inner cavity 14.
[0031] Specifically, the buffer 13 includes a damper and a second spring. The second spring is sleeved on the outside of the damper. Through the synergistic effect of the damper and the spring, the vibration reduction effect is significantly improved, and the flutter during the honing process is effectively suppressed.
[0032] A buffer plate 11 is fixed to the top of the buffer component 13. A sealing gasket is provided on the outside of the buffer plate 11. The sealing gasket is movably attached to the inner wall of the inner cavity 14 to prevent lubricating oil leakage.
[0033] In actual operation of this utility model, when the extrusion head 15 moves downward, it will squeeze the buffer plate 11 and the buffer member 13, thereby using the elastic force of the buffer member 13 to push the extrusion head 15 back to its original position. The buffer member 13 can also buffer the vibration of the extrusion head 15, making the up-and-down movement of the extrusion head 1 more stable.
[0034] Furthermore, when lubricating oil is introduced into the inner cavity 14, the elastic force of the buffer 13 can push the lubricating oil upward, allowing it to rise to a higher position to lubricate the extrusion head 15 and honing rod 1. This not only provides lubrication and cooling but also enhances the vibration reduction effect. By effectively controlling the vibration during the honing process, it reduces processing errors caused by chatter, improves the surface quality and processing efficiency, reduces thermal and mechanical damage to the honing rod and workpiece, and extends the service life of the equipment.
[0035] The honing head 3 has a sleeve 6 connected to its top end. The lubricating oil inlet 7 is located on the outside of the sleeve 6, and the sleeve 6 is also fitted onto the outside.
[0036] A first spring 2 is sleeved on the outer side of the honing rod 1.
[0037] Multiple fixed ends 4 are telescopically arranged around the honing head 3. Each honing head 3 has a groove 9 at its top. Elastic rings 10 are installed between the multiple grooves 9. The design of multiple fixed ends 4 and elastic rings 10 further enhances the stability and reliability of the structure and can help the multiple extended fixed ends 4 to reset and retract.
