Description

Technical Field

[0001] This utility model relates to the field of machine tool manufacturing technology, specifically a single-axis double-blade micro-vibration honing head. Background Technology

[0002] Honing is a finishing process that uses an oilstone embedded in the honing head to perform micro-grinding on the pre-machined hole wall. Its core feature is that high-precision surface treatment is achieved through the combined motion of the oilstone and the inner hole of the workpiece.

[0003] Dual-station honing machines are required in the honing process of workpieces. The working principle of existing dual-station honing machines can be summarized as follows: two main motors, two independent main drive systems and spindles drive their respective honing heads, which can work synchronously to achieve parallel processing of two holes.

[0004] Although a dual-station honing machine can process two workpieces simultaneously, this solution requires two main motors, two independent main drive systems and spindles, resulting in high equipment manufacturing costs. Therefore, a single-axis dual-blade micro-vibration honing head is proposed to solve the problems mentioned above. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a single-axis double-blade micro-vibration honing head, which has the advantages of simplifying the structure of the honing machine, reducing the equipment manufacturing cost, reducing the equipment footprint, and improving its competitiveness in the market, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A single-axis dual-blade micro-vibration honing head includes a main motor, a first driven shaft, a second driven shaft, and honing blades. The main motor is externally equipped with a speed-changing synchronization component for realizing parallel machining of two holes.

[0008] The speed-changing synchronization assembly includes a gearbox body fixedly installed outside the main motor. A main shaft bearing seat is movably connected to the top of the gearbox body. Driven bearing seats and guide bearing seats are fixedly installed on the left and right sides of the top of the gearbox body. A guide shaft is fixedly connected to the inner side of the guide bearing seat. A drive synchronous pulley is fixedly connected to the main shaft of the main motor. A synchronous belt is provided outside the drive synchronous pulley. Driven synchronous pulleys are fixedly connected to the outside of the first driven shaft and the second driven shaft.

[0009] Furthermore, a tensioning support is fixedly installed near the spindle bearing housing, and an adjusting bolt for tension adjustment is threaded onto the inner side of the tensioning support.

[0010] Furthermore, pneumatic chucks are fixedly installed at the bottom ends of both the first driven shaft and the second driven shaft, and a chuck sleeve for fixing the honing tool is fixedly installed at the bottom end of the pneumatic chuck.

[0011] Furthermore, the main shaft of the main motor is fixedly connected to the inner side of the main shaft bearing housing, and the outer surfaces of the first driven shaft and the second driven shaft are respectively fixedly connected to the inner sides of two driven bearing housings.

[0012] Furthermore, the active synchronous pulley is driven by the driven synchronous pulley via a synchronous belt.

[0013] Furthermore, the first driven shaft and the second driven shaft are the same size, and both the first driven shaft and the second driven shaft are provided with end caps for sealing and dust prevention on their outer surfaces.

[0014] Furthermore, the gearbox body is made of stainless steel, and a dust cover is fixedly installed on the top of the gearbox body.

[0015] Furthermore, a main drive system is provided on the outside of the main motor, and through holes are provided on the outside of the gearbox body for positioning and mounting the main motor spindle, the first driven shaft and the second driven shaft.

[0016] Compared with the prior art, this utility model provides a single-axis double-blade micro-vibration honing head, which has the following beneficial effects:

[0017] 1. This single-axis dual-blade micro-vibration honing head, through the setting of a speed-changing synchronization component, transmits rotational torque from the main motor's spindle to the first and second driven shafts via the cooperation of the active synchronous pulley, synchronous belt, and driven synchronous pulley. Subsequently, this rotational torque is transmitted to the honing blades through the pneumatic chuck and blade holder, thereby simultaneously driving the two honing blades to rotate synchronously. Ultimately, the two honing blades hone the inner holes of two workpieces simultaneously. Compared with existing technologies, the main drive system of the main motor is simplified from two sets to one. During this process, the synchronization of the honing of the two workpieces is greatly improved, while the equipment cost is significantly reduced, enhancing the equipment's competitiveness in the market.

[0018] 2. This single-axis double-blade micro-vibration honing head, through the cooperation of the tension support and the adjusting bolt, allows the operator to turn the adjusting bolt clockwise or counterclockwise. By adjusting the axial position of the adjusting bolt, the spindle bearing seat is driven to move longitudinally along the waist hole on its outer surface. This changes the position of the driving synchronous belt pulley, ensuring that the synchronous belt is always in a taut state. This allows the first driven shaft and the second driven shaft to output sufficient torque, ensuring that the honing process can proceed normally. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3 The single-axis dual-blade micro-vibration honing head in this embodiment includes a main motor 1, a first driven shaft 2, a second driven shaft 3, and a honing blade 16. A speed-changing synchronization assembly for parallel machining of two holes is externally mounted on the main motor 1. The speed-changing synchronization assembly includes a gearbox body 4 fixedly mounted externally to the main motor 1. A main shaft bearing seat 5 is movably connected to the top of the gearbox body 4. Driven bearing seats 6 and guide bearing seats 7 are fixedly mounted on the left and right sides of the top of the gearbox body 4. A guide shaft 8 is fixedly connected to the inner side of the guide bearing seat 7. A drive synchronous pulley 9 is fixedly connected to the main shaft of the main motor 1. A synchronous belt 10 is provided externally to the drive synchronous pulley 9. Driven synchronous pulleys 11 are fixedly connected externally to the first driven shaft 2 and the second driven shaft 3. The main shaft of the main motor 1 transmits rotational torque to the first driven shaft 2 and the second driven shaft 3 through the belt drive cooperation between the drive synchronous pulley 9, the synchronous belt 10, and the driven synchronous pulleys 11.

[0025] Subsequently, the rotational torque is transmitted to the honing cutter 16 through the pneumatic chuck 14 and the tool holder 15, thereby simultaneously driving the two honing cutters 16 to rotate synchronously. Finally, the two honing cutters 16 hone the inner holes of the two workpieces at the same time.

[0026] Compared with existing technologies, the main drive system of the main motor 1 is simplified from two sets to one. During this process, the synchronization of the honing process of the two workpieces is greatly improved, while the equipment cost is significantly reduced, thus enhancing the competitiveness of the equipment in the market.

[0027] In this embodiment, a tensioning support 12 is fixedly installed near the spindle bearing housing 5. An adjusting bolt 13 for tension adjustment is threaded onto the inner side of the tensioning support 12. The operator can turn the adjusting bolt 13 clockwise or counterclockwise to adjust its axial position, thereby causing the spindle bearing housing 5 to move longitudinally along the slot on its outer surface. This changes the position of the driving synchronous pulley 9, ensuring that the synchronous belt 10 remains taut. This allows the first driven shaft 2 and the second driven shaft 3 to output sufficient torque, ensuring the honing process proceeds normally.

[0028] It should be noted that pneumatic chucks 14 are fixedly installed at the bottom ends of both the first driven shaft 2 and the second driven shaft 3. A clamping sleeve 15 for fixing the honing cutter 16 is fixedly installed at the bottom end of the pneumatic chuck 14. The pneumatic chuck 14 is a device that can use air pressure to quickly clamp or release the honing cutter 16. During this process, the clamping sleeve 15 can instantly complete the clamping or releasing action through air pressure control, which significantly improves production efficiency and is especially suitable for high-frequency, large-volume processing scenarios.

[0029] Specifically, the main shaft of the main motor 1 is fixedly connected to the inner side of the main shaft bearing housing 5, and the outer surfaces of the first driven shaft 2 and the second driven shaft 3 are respectively fixedly connected to the inner sides of two driven bearing housings 6. The main shaft bearing housing 5 and the driven bearing housing 6 provide a stable mounting base for the main shaft of the main motor 1, the first driven shaft 2 and the second driven shaft 3, ensuring that they maintain the correct position and angle during operation.

[0030] It should be noted that the driving synchronous pulley 9 is driven by the driven synchronous pulley 11 via the synchronous belt 10.

[0031] It should be noted that the first driven shaft 2 and the second driven shaft 3 are the same size. Both the first driven shaft 2 and the second driven shaft 3 have end caps 17 for sealing and dust prevention on their outer surfaces. The gearbox body 4 is made of stainless steel. A dust cover is fixedly installed on the top of the gearbox body 4. The end caps 17 and the dust cover play a role in sealing and dust prevention, which can reduce the impact of dust on the main shaft of the main motor 1, the first driven shaft 2 and the second driven shaft 3.

[0032] Specifically, the main motor 1 is provided with a main drive system on its exterior, and the gearbox body 4 is provided with through holes for positioning and mounting the main shaft of the main motor 1, the first driven shaft 2, and the second driven shaft 3.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, the main shaft of the main motor 1 transmits rotational torque to the first driven shaft 2 and the second driven shaft 3 through the belt drive between the active synchronous pulley 9, the synchronous belt 10 and the driven synchronous pulley 11. Then, the rotational torque is transmitted to the honing cutter 16 through the pneumatic chuck 14 and the tool holder 15, thereby driving the two honing cutters 16 to rotate synchronously. Finally, the two honing cutters 16 hone the inner holes of the two workpieces at the same time.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.

[0036] It should be noted that the orientations or positional relationships indicated herein are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
