[0001] The utility model relates to the technical field of slewing bearing processing, in particular to a high-pad tooling for hobbing machines for slewing bearing hobbing, etc. Background Art

[0002] When slewing bearings are subjected to hobbing processing, the slewing bearings need to be clamped. Since the diameters of the slewing bearings for hobbing processing on a set of equipment are different, for the hobbing processing of slewing bearings with different diameters, for the current clamping tooling for slewing bearings, the clamping range of this clamping tooling for slewing bearings with different diameters is limited, and it can only be applicable to the clamping of slewing bearings with approximate diameters. Due to the limited adjustment range, it is not applicable to the clamping of slewing bearings with a large diameter difference. Content of the Utility Model

[0003] The purpose of the utility model is to provide a high-pad tooling for hobbing machines for slewing bearing hobbing. The high pads are assembled in two ways, with a large adjustment range, and can realize the clamping of slewing bearings of different sizes and dimensions. The clamping range is larger, the application range is wider, and the adjustment is convenient and flexible, which can solve the problems in the prior art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A high-pad tooling for hobbing machines for slewing bearing hobbing, including a disc seat. The disc seat is fixedly installed with high pads through first bolts, and the top of the high pads clamps the slewing bearing through a clamping mechanism installed thereon.

[0006] Further, a guide block is integrally provided at the bottom of the high pad, and the guide block is fitted into a first installation groove with a T-shaped cross-section opened on the disc seat.

[0007] Further, waist-shaped grooves are opened on both the disc seat and the high pads, and the first bolts pass through the waist-shaped grooves on the disc seat and the high pads and are threadedly connected to first inserts embedded inside the first installation groove.

[0008] Further, the clamping mechanism includes a pressing plate, a second bolt, a spacer and a second insert. The stud at the bottom of the pressing plate is threadedly connected to the spacer, and the bottom of the spacer is placed on the high pad. The second bolt passes through the waist-shaped groove opened on the pressing plate and is threadedly connected to the spacer embedded inside the second installation groove opened on the high pad.

[0009] Further, a slewing bearing is placed between the pressing plate and the high pad.

[0010] Further, the high pad is provided in an L shape.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The equal-height pads of the present utility model are set in an L shape to ensure a larger adjustment range. When the bottom plates of the equal-height pads are installed inward, the distance between the vertical plates of each equal-height pad is relatively large, which is suitable for clamping a slewing bearing with a larger diameter. Moreover, by dragging the equal-height pads back and forth, the installation position of the equal-height pads can be adjusted, and the clamping of slewing bearings with different diameters can be achieved through the clamping mechanism. When the bottom plates of the equal-height pads are installed outward, the clamping mechanism is still installed in the same direction, and the vertical plates of each equal-height pad move closer to each other, with a smaller distance between the vertical plates of each equal-height pad. By using the same method to clamp the slewing bearing, the clamping of a slewing bearing with a smaller diameter can be achieved. Overall, the present utility model realizes the clamping of slewing bearings with a relatively large diameter span, is applicable to the clamping of slewing bearings of different sizes, has a larger clamping range, a wider application range, and is convenient and flexible to adjust.

Detailed Embodiment

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Refer to Figure 1-2, A height equalizing pad tooling for hobbing of slewing bearings, including a disc seat 1, the disc seat 1 is installed on the turntable of the hobbing machine, the disc seat 1 is fixedly installed with a height equalizing pad 2 through a first bolt 5. Waist-shaped grooves are provided on both the disc seat 1 and the height equalizing pad 2. The first bolt 5 passes through the waist-shaped grooves on the disc seat 1 and the height equalizing pad 2 and is threadedly connected to a first insert block 8 embedded inside a first installation groove 7, so that the height equalizing pad 2 can be fastened to the disc seat 1.

[0020] Refer to Figure 1-3 , A guide block 6 is integrally provided at the bottom of the height equalizing pad 2. The guide block 6 is fitted with a first installation groove 7 having a T-shaped cross section provided on the disc seat 1. The function of the guide block 6 is to ensure that the height equalizing pad 2 is stable on the disc seat 1 and the guide block 6 will not shake. Moreover, the height equalizing pad 2 can be installed relatively quickly through the guide block 6.

[0021] Refer to Figure 4 , The clamping mechanism 3 includes a pressure plate 31, a second bolt 32, a shim 33 and a second insert block 34. The stud at the bottom of the pressure plate 31 is threadedly connected to the shim 33. The bottom of the shim 33 is placed on the height equalizing pad 2. The second bolt 32 passes through the waist-shaped groove provided on the pressure plate 31 and is threadedly connected to the shim 33 embedded inside a second installation groove 9 provided on the height equalizing pad 2. The shim 33 serves to lift the pressure plate 31 at the tail of the pressure plate 31 and also serves as a fulcrum. Turning the second bolt 32 can press the pressure plate 31 downward.

[0022] The slewing bearing 4 is clamped by the installed clamping mechanism 3 at the top of the height equalizing pad 2. The space between the pressure plate 31 and the height equalizing pad 2 is for placing the slewing bearing 4. After placing the slewing bearing 4 between the pressure plate 31 and the height equalizing pad 2, the slewing bearing 4 can be pressed tightly by turning the second bolt 32.

[0023] Each height equalizing pad 2 is equipped with a clamping mechanism 3. The height equalizing pad 2 is used to lift the slewing bearing 4 to a suitable height. The number of height equalizing pads 2 can be set according to actual usage needs. The arrangement of 6 height equalizing pads 2 is shown in this utility model.

[0024] The height equalizing pad 2 is set in an L shape to ensure that when the height equalizing pad 2 is installed in two ways, the adjustment range is larger, the applicable range is wider, and it can be applicable to slewing bearings 4 with a relatively large diameter difference.

[0025] The usage process of this utility model:

[0026] The first usage method (such as Figure 1-2):For the slewing bearing 4 with a relatively large diameter, place the first insert block 8 into the first installation groove 7. The equal-height pad 2 slides into the first installation groove 7 through the guiding block 6. Place the slewing bearing 4 between the pressure plate 31 and the equal-height pad 2. Pull the equal-height pad 2 outwards until it cannot be pulled further. Tighten the slewing bearing 4 by screwing the second bolt 32 through the pressure plate 31. For slewing bearings 4 with a large diameter difference, the clamping of slewing bearings 4 with a relatively small diameter difference can be achieved by dragging and adjusting the equal-height pad 2.

[0027] The second usage method (such as Figure 4 ):For the slewing bearing 4 with a relatively small diameter, the diameter of this type of slewing bearing 4 has a relatively large difference from the above-mentioned slewing bearing 4. Since the equal-height pad 2 is L-shaped, the above installation method of the equal-height pad 2 cannot meet the clamping of the slewing bearing 4 with a relatively small diameter. At this time, rotate the equal-height pad 2 by 180 degrees for installation, and the clamping mechanism 3 still maintains the same installation direction. In this way, the equal-height pads 2 move closer to each other, which is suitable for the clamping of the slewing bearing 4 with a relatively small diameter.
