The spindle is equipped with a cutting tool for gear hobbing, which includes a tool holder and a hobbing cutter mounted on the tool holder. The spindle is usually connected to a motor, and the spindle rotates under the drive of the motor, thereby rotating the cutting tool and achieving the gear hobbing process.

[0003] After prolonged use, the surface of the hobbing cutter will wear down and need to be replaced. A search reveals, for example, a Chinese patent application with publication number CN202746157U, which discloses a CNC hobbing and chamfering integrated machine. This machine includes a base and horizontal and vertical slides mounted on the base. A slide table and a spindle box and servo motor are mounted on the horizontal slide table. A hobbing cutter is mounted on one vertical slide table, and an arc-shaped rail slide table is stacked on the other vertical slide table.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-9The spindle tool mounting mechanism of a gear hobbing machine shown includes a main body 1. An extension plate 2 is provided on the top of the outer wall of the main body 1. A fixing mechanism 3 is provided on the top of the extension plate 2 for mounting the spindle tool. The fixing mechanism 3 includes a mounting plate 31, which is fixedly connected to the extension plate 2 and the top of the main body 1 by bolts. A lifting plate 32 is symmetrically fixedly connected to the top of the mounting plate 31. A sliding rail 33 is fixedly connected to the top of the lifting plate 32. A longitudinal slide 34 is slidably connected inside the sliding rail 33. A U-shaped plate 35 is fixedly connected to the bottom of the longitudinal slide 34. A mounting chamber 36 is fixedly connected to the outer wall of the longitudinal slide 34. An adjustment component 37 is provided inside the mounting chamber 36 for adjusting the spindle tool. The adjustment component 37 includes a rotating part 371. A grinding part 372 is installed at the bottom of the rotating part 371. An adjustment part 373 is provided at the bottom of the grinding part 372.

[0018] It is important to note that, such as Figure 2 As shown, the extension plate 2 and the mounting plate 31 have through slots at their rear ends. When it is necessary to remove or install the spindle tool, the operator slides the longitudinal slide 34 to move the entire longitudinal slide 34 into the through slot, making it convenient to remove the spindle tool.

[0019] To facilitate the installation of the spindle tool and to enable the spindle tool to rotate after installation, such as Figure 4-7 As shown, the rotating component 371 includes a servo motor 3711, which is fixedly connected to the top of the mounting chamber 36. The output end of the servo motor 3711 is fixedly connected to a rotating disk 3712. The grinding component 372 includes a grinding cylinder 3722, with an inner cavity 3726 at the top. A damping component 3727 is fixedly connected to the bottom of the inner cavity 3726, and a fixing block 3721 is fixedly connected to the top of the damping component 3727. A buffer spring 3728 is sleeved on the surface of the damping component 3727. The two ends of the buffer spring 3728 are fixedly connected to the bottom of the inner cavity 3726 and the bottom of the fixing block 3721, respectively. The fixing block 3721 is snapped into the space at the bottom of the rotating disk 3712 to fix the rotating component 371.

[0020] When installing the spindle tool, the operator first inserts the grinding part 372 into the through hole, so that the fixing block 3721 can be aligned with the space at the bottom of the rotary disk 3712 to fix the grinding part 372. During processing, the operator starts the servo motor 3711. The rotation of the servo motor 3711 can drive the rotation of the rotary disk 3712, which in turn drives the grinding cylinder 3722 to rotate. The rotation of the grinding cylinder 3722 can grind the spindle.

[0021] To better secure the grinding barrel 3722, such as Figure 4-7As shown, the surface of the grinding cylinder 3722 is provided with multiple sliding grooves 3723. A sliding plate 3724 is slidably connected inside the sliding grooves 3723. An annular guide rail 3725 is fixedly connected to the bottom of the longitudinal slide block 34. Multiple guide rail blocks 3729 are slidably connected inside the annular guide rail 3725. The guide rail blocks 3729 are engaged with the sliding plate 3724. During the rotation of the grinding cylinder 3722, the sliding plate 3724 can be driven to rotate. The rotation of the sliding plate 3724 can drive the guide rail blocks 3729 to rotate along the annular guide rail 3725, making the grinding cylinder 3722 more stable.

[0022] Considering that during the grinding process, only the middle part of the grinding cylinder 3722 contacts the gear blank, and the middle part of the grinding cylinder 3722 wears out faster while the two ends are still usable, disassembling the entire grinding cylinder 3722 at this point would easily result in waste. To avoid waste, such as Figure 9 As shown, the adjusting component 373 includes a fixing plate 3732. A circular hole is provided at the bottom of the U-shaped plate 35. The fixing plate 3732 is snapped into the circular hole. When the fixing plate 3732 is snapped in, the top of the fixing plate 3732 contacts the top of the U-shaped plate 35. An electric telescopic rod 3731 is fixedly connected to the top of the fixing plate 3732. A fixing cylinder 3733 is fixedly connected to the top of the electric telescopic rod 3731. A grinding cylinder 3722 is inserted inside the fixing cylinder 3733. When a certain position of the grinding cylinder 3722... When significant wear occurs in a section, the operator can activate the electric telescopic rod 3731. The retraction of the electric telescopic rod 3731 will cause the grinding cylinder 3722 to move downwards. At this time, the damping component 3727 will be stretched, causing the buffer spring 3728 to stretch and buffer the adjustment component 37. Through the above method, the worn part can be moved to the bottom of the gear blank, and the new unworn part can be moved to the surface of the gear blank. By using the above method, the replacement frequency of the grinding cylinder 3722 can be reduced, and the processing efficiency can be improved.

[0023] It is worth noting that because the top of the sliding plate 3724 is engaged with the guide block 3729, when the grinding cylinder 3722 is pulled by the adjusting piece 373, the sliding plate 3724 will slide along the slide groove 3723. At the same time, in order to facilitate the removal of the adjusting piece 373, an embedded handle is provided at the bottom center of the fixing plate 3732 to facilitate the removal of the adjusting piece 373.

[0024] Finally, it should be noted that a central hole is provided at the bottom center of the longitudinal slide 34 and the mounting chamber 36. The central hole is concentric with the circular hole. The grinding part 372 is inserted into the central hole to fix it inside the mounting chamber 36.
