Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of slewing bearing processing, in particular to a horizontal machining center tooling for boring plugging holes and drilling oil holes of a slewing bearing. Background Art
[0002] Some large slewing bearings need to be processed with holes and oil holes. When processing holes and oil holes on large slewing bearings, the large slewing bearings need to be clamped and fixed. At present, for the clamping of slewing bearings with relatively large diameters, the pressure plate lacks a limit at the tail, which causes the pressure plate that presses the large slewing bearing to move. The pressure on the large slewing bearing is not strong enough, which seriously affects the processing of holes and oil holes on the side of the large slewing bearing. Utility Model Content
[0003] The purpose of the utility model is to provide a horizontal machining center tooling for boring plugging holes and drilling oil holes of a slewing bearing. By limiting the tail of the pressure plate, it is ensured that the pressure plate will not move or deviate during clamping, so that normal processing of holes and oil holes on the side of a large slewing bearing can be achieved, which can solve the problems in the prior art.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A horizontal machining center tooling for boring plugging holes and drilling oil holes for slewing bearings comprises a base and cross-shaped adjusting claws mounted on the base by connecting bolts, each of the adjusting claws is mounted with a clamping member, the clamping member comprises a pillar, two semicircular blocks integrally arranged on the top of the pillar, a support block, a pressure plate and a clamping bolt, the support block is mounted on the top of the pillar by a limiting bolt, the support block is connected to the pressure plate by a connecting bolt, and the pressure plate is locked by a clamping bolt.
[0006] Furthermore, the inner side of the support block is configured as an arc edge that fits with the outer edge of the semicircular block.
[0007] Furthermore, the bottom of the support column is connected to the first T-shaped sliding block in the T-shaped slot of the adjusting claw through a connecting bolt.
[0008] Furthermore, the bottom of the clamping bolt is connected to the second T-shaped sliding block in the T-shaped slot at the upper end of the support.
[0009] Furthermore, a circular hole through which a clamping bolt passes is provided in the middle of the two semicircular blocks.
[0010] Furthermore, the top of the pillar has an area located at the periphery of the outermost semicircular block for placing the slewing bearing.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] The utility model arranges two semicircular blocks on the top of each pillar, and reserves two blank areas on the periphery of the semicircular blocks, one blank area is used to place a large slewing bearing, and the other blank area is used to install a support block, the inner arc edge of the support block can fit with the outer wall of the semicircular block, and the support block is fixed to the pillar by two limiting bolts. The shape setting of the support block and the fixing setting of the limiting bolts can ensure that the pressure plate is parallel to the adjusting claw, limit and fix the fulcrum of the pressure plate, thereby ensuring the stability of the pressure plate and preventing active deviation, which is conducive to pressing the large slewing bearing, preventing the slewing bearing from moving during processing, and facilitating the processing of holes and oil eyes on the side of the large slewing bearing.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-Figure 4A horizontal machining center tooling for boring plugging holes and drilling oil holes for slewing bearings comprises a base 1 and cross-shaped adjusting claws 2 installed on the base 1 by connecting bolts. The adjusting claws 2 are relatively long and extend outward from the base 1. The length of the adjusting claws 2 is based on the large-sized slewing bearing, so that the adjusting claws 2 have a larger adjustment range and can adapt to the clamping of a large slewing bearing 4. A clamping member 3 is installed on each adjusting claw 2, and the clamping member 3 is used to clamp the large slewing bearing 4 to keep it stable.
[0021] See also Figure 5 The clamping member 3 includes a pillar 31, two semicircular blocks 32 integrally arranged at the top of the pillar 31, a support block 33, a pressure plate 34 and a clamping bolt 35. The support block 33 is installed on the top of the pillar 31 through a limiting bolt 36. The support block 33 is locked on the pillar 31 through two connecting bolts (distributed on both sides of the support block 33). In this way, the stability of the support block 33 can be ensured. By limiting the position of the support block 33, the support block 33 will not move. The support block 33 is connected to the pressure plate 34 through the connecting bolts. The support block 33 supports the pressure plate 34 at one end as a fulcrum of the pressure plate 34. The pressure plate 34 is locked by the clamping bolt 35. When the clamping bolt 35 is tightened, the pressure plate 34 can be pressed downward, thereby clamping the large slewing bearing 4.
[0022] The inner side of the support block 33 is configured to be an arc edge that fits with the outer edge of the semicircular block 32. Since each pillar 31 has two semicircular blocks 32, the diameters of the two semicircular blocks 32 are smaller than the diameter of the pillar 31, and there is a certain amount of space around the two semicircular blocks 32. The above-mentioned support block 33 is installed around the periphery of one of the semicircular blocks 32. The semicircular blocks 32 fit well with the support blocks 33 to ensure that the position of the support block 33 will not move. The top of the pillar 31 has an area for placing a slewing bearing around the outermost semicircular block 32, and the outer arc edge of the other semicircular block 32 can fit with the inner side of the large slewing bearing. The bottom end of the large slewing bearing 4 can be placed on the space around the semicircular block 32 (the space is the blank space at the top of the pillar 31).
[0023] The bottom of the support column 31 is connected to the first T-shaped slider in the T-shaped slot of the adjusting claw 2 via a connecting bolt, and the support column 31 can be moved and adjusted via the first T-shaped slider.
[0024] The bottom of the clamping bolt 35 is connected to the second T-shaped slider in the T-shaped slot at the upper end of the support 31 , and the second T-shaped slider is used at the bottom to realize the clamping action of the clamping bolt 35 .
[0025] A circular hole for a clamping bolt 35 to pass through is provided in the middle of the two semicircular blocks 32 . The clamping bolt 35 passes downward from the middle of the two semicircular blocks 32 to be connected with the second T-shaped sliding block.
[0026] Working principle: fit the inner side of the support block 33 with the outer wall of one of the semicircular blocks 32, tighten the two limit bolts 36, fix the support block 33 on the pillar 31, adjust the clamp 3 to a suitable position, place the large slewing bearing on the step at the top of the pillar 31, fit the inner side of the large slewing bearing 4 with the outer wall of the outermost semicircular block 32, move the clamp 3 outward until the outer wall of the outermost semicircular block 32 is tightly attached to the inner side of the large slewing bearing, tighten the clamping bolt 35, press the pressure plate 34 downward, and tighten the large slewing bearing. The holes and oil eyes of the large slewing bearing are processed by processing equipment, and the loosening of the large slewing bearing 4 due to the movement of the pressure plate 34 will not affect the processing of the holes and oil eyes.
