Description

Technical Field

[0001] This utility model relates to the field of honing head technology, and more specifically, to a honing head with multiple oilstone guards. Background Technology

[0002] Honing is a high-precision machining process that is widely used in the field of mechanical manufacturing, especially in the precision machining of internal holes, external circles and complex curved surfaces. Traditional honing heads usually adopt a fixed oilstone structure.

[0003] A search revealed Chinese patent CN216940084U, which discloses an ultra-precision small-hole multi-stone center-adjustable honing head. This invention addresses the shortcomings of existing honing heads, such as the gradual reduction of the abrasive layer with increasing processing cycles, easy abrasive shedding, the need for frequent dimensional adjustments by the operator, long auxiliary processing time, and short honing head lifespan, failing to meet the mass production needs of high-end customers. Furthermore, traditional honing heads have a rigid, integral structure, which cannot achieve automatic alignment during honing. This invention addresses these issues by using upper and lower locking nuts to achieve stable control of the honing stone's dimensional accuracy. By coordinating the honing stone and the honing head body, the honing stone can expand stably within an effective adjustment range. Finally, by using connecting pins, the honing head body can move omnidirectionally relative to the honing linkage, ensuring the honing head body has an automatic alignment function.

[0004] The honing stones in honing heads are usually fixed by bonding or mechanical clamping. The disassembly and assembly process is complicated and time-consuming, resulting in high maintenance costs and low production efficiency. When the honing stone wears out or needs to be replaced, it often requires a long downtime, which affects processing efficiency. The honing stone is easily affected by the impact of uneven workpiece surfaces, hard particles or processing debris, which leads to severe wear on the edges of the honing stone and a shortened service life. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, this utility model provides a multi-oilstone wing type honing head to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a honing head with multiple oilstone guards, comprising a honing head, an oilstone mounted on the outside of the honing head, guards fixedly connected to both sides of the oilstone, and a disassembly and assembly mechanism provided between the honing head and the oilstone.

[0007] The disassembly and assembly mechanism includes a mounting connecting plate, which is fixed to one side of the honing stone. The top surface of the mounting connecting plate has a threaded groove, and a connecting pipe is fixedly connected to one side of the mounting connecting plate. One side surface of the honing head has a mounting slot, and the top surface of the honing head has a threaded hole. Mounting bolts are provided inside both the threaded hole and the threaded groove. A coolant flow mechanism is provided between the mounting connecting plate and the honing head.

[0008] Preferably, the coolant flow mechanism includes a connecting hole, which is formed on one side of the inner wall of the mounting slot. A sealing ring is fixedly connected inside the connecting hole, and the connecting pipe is movably engaged with the connecting hole.

[0009] Preferably, the honing head has a coolant cavity inside, the mounting plate is hollow, and one end of the connecting pipe passes through the honing head and extends into the coolant cavity.

[0010] Preferably, both the threaded groove and the threaded hole are threadedly connected to the mounting bolt.

[0011] Preferably, the honing head is fixedly connected to both the top and bottom of a fixing block, and the number of fixing blocks is set to two, one of which is fixedly connected to a fixing plate on its top.

[0012] Preferably, an installation head is fixedly installed on the top of the fixing plate, and a liquid replenishment groove is opened inside the honing head and one of the fixing blocks.

[0013] Preferably, a replenishment pipe is fixedly installed on one side of one of the fixing blocks, and one end of the replenishment pipe passes through the fixing block and extends into the replenishment tank.

[0014] Preferably, the protective wing is made of polyurethane.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting up a disassembly and assembly mechanism, the honing stone can be quickly installed and replaced. The honing stone is fixed to the honing head by the mounting plate and mounting bolts. The design of the threaded groove and threaded hole makes the disassembly and assembly process simple and efficient, significantly reducing maintenance time and cost and improving production efficiency. The protective wings are made of polyurethane material and are fixed on both sides of the honing stone. They can effectively prevent the honing stone from being subjected to external impact or wear during processing. At the same time, the flexible material of the protective wings can absorb the vibration generated during processing, improve processing stability, reduce vibration marks and defects on the workpiece surface, and significantly improve processing quality.

[0017] 2. By incorporating a coolant circulation mechanism, coolant enters the replenishment tank from the replenishment pipe and is evenly distributed to the processing areas of each honing stone through the coolant chamber and connecting pipe. Sealing rings are installed in the connection holes to ensure no coolant leakage. The coolant circulation effectively reduces the temperature of the honing stone and workpiece, reduces friction, improves processing accuracy, and extends the service life of the honing stone. The combination of the assembly / disassembly mechanism, the protective wings, and the coolant circulation mechanism makes the honing head widely applicable, capable of adapting to the processing needs of workpieces of different materials and shapes, while simultaneously reducing manufacturing costs and maintenance difficulty.

A threaded groove 5 is provided on the top surface of the mounting connecting plate 4. A connecting pipe 6 is fixedly connected to one side of the mounting connecting plate 4. A mounting slot 7 is provided on one side surface of the honing head 1. A threaded hole 11 is provided on the top surface of the honing head 1. Mounting bolts 12 are provided inside both the threaded hole 11 and the threaded groove 5. A coolant flow mechanism is provided between the mounting connecting plate 4 and the honing head 1.

[0027] As attached Figure 3 , 4 As shown, the coolant flow mechanism includes a connecting hole 8, which is opened on one side of the inner wall of the mounting slot 7. A sealing ring 9 is fixedly connected inside the connecting hole 8. The connecting pipe 6 is movably engaged with the connecting hole 8, which facilitates the connection between the connecting pipe 6 and the coolant chamber 10, while preventing coolant leakage from the connecting hole 8.

[0028] As attached Figure 3 , 4 As shown, the honing head 1 has a coolant cavity 10 inside, the mounting connecting plate 4 is hollow, and one end of the connecting pipe 6 passes through the honing head 1 and extends into the coolant cavity 10, so that the coolant can flow through the connecting pipe 6 to carry away the heat.

[0029] As attached Figure 1-5 As shown, both the threaded groove 5 and the threaded hole 11 are threadedly connected to the mounting bolt 12, which improves the fixing effect of the mounting connecting plate 4 and the honing head 1, thereby ensuring the installation firmness of the honing head 1 and the honing stone 2.

[0030] As attached Figure 1 , 2 As shown in Figure 4, the honing head 1 is fixedly connected to both the top and bottom of a fixing block 13. There are two fixing blocks 13. The top of one fixing block 13 is fixedly connected to a fixing plate 14. The top of the fixing plate 14 is fixedly mounted with an installation head 15, which facilitates the installation of the honing head 1 on the drive device. The honing head 1 and one of the fixing blocks 13 are both provided with a coolant reservoir 16. A coolant pipe 17 is fixedly mounted on one side of one of the fixing blocks 13.

[0031] As attached Figure 1 , 2 As shown, the protective wing 3 is made of polyurethane, which improves the cushioning effect and provides protection against the whetstone.

[0032] The working principle of this utility model is as follows: The honing stone 2 is fixed to the outside of the honing head 1 through the disassembly and assembly mechanism. A mounting connecting plate 4 is fixed on one side of the honing stone 2. The mounting connecting plate 4 is connected to the honing head 1 through the mounting bolt 12.

The protective wings 3 are fixed on both sides of the honing stone 2 and are made of polyurethane material. The protective wings 3 prevent the honing stone 2 from being subjected to external impact or wear during processing. The flexible material of the protective wings 3 can absorb the vibration generated during processing and improve processing stability. The coolant enters the coolant tank 16 from the coolant pipe 17 and is then distributed to the processing area of ​​each honing stone 2 through the coolant chamber 10. The coolant flows through the connecting pipe 6 and the connecting hole 8. The connecting hole 8 is equipped with a sealing ring 9 to ensure that the coolant does not leak. The flow reduces the temperature of the honing stone 2 and the workpiece, reduces friction, improves processing quality, and extends the service life of the honing stone 2.

[0033] The honing head 1 is connected to the honing machine via the mounting head 15. After starting, the honing head 1 begins to rotate and reciprocate along the axial direction. The honing stone 2 grinds the surface of the workpiece under the drive of the honing head 1. The protective wing 3 protects the honing stone 2 and reduces vibration. The coolant is evenly distributed to the contact area between the honing stone 2 and the workpiece through the coolant circulation mechanism, which plays a cooling role. After the processing is completed, the honing head 1 stops moving, the coolant stops flowing, and the surface of the workpiece reaches the required precision and smoothness.
