Abstract
The utility model provides a main shaft of a milling head and a boring head. A bearing is arranged on a main shaft body; screw threads are arranged on the main shaft body of the two sides of the bearing; a compression nut for compressing the bearing is arranged on the screw thread at the small diameter end of the main shaft body; and a dismounting nut for dismounting the bearing is arranged on the screw thread at the large diameter end of the main shaft body. When the bearing on the main shaft body is damaged and needs to be dismounted, the dismounting nut is rotated to move to the small diameter end of the main shaft body along the screw threads of the main shaft body and to be pushed against the bearing of the main shaft until the bearing of the main shaft is loosened; with the adoption of the mode, the stress is uniform stress, the dismounting is convenient, and the bearing of the main shaft can be taken down without being beaten or taking other complex methods; and the main shaft of the milling head and the boring head is convenient for dismounting the bearings of the main shafts of the milling head and the boring head and is convenient, fast and practical to use.
Description
Technical field
The utility model relates to a kind of milling head, boring head main shaft.
Background technology
Traditional milling head, boring head main shaft are made up of clamp nut 1, packing ring 2, bearing 3, main shaft 4, as shown in Figure 1.Bearing 3 is contained on the main shaft 4, and packing ring 2 is close to bearing 3, and clamp nut 1 is realized packing washer 2 by the screw thread on the relevant position on the main shaft 4, thereby compresses bearing 3.Bearing 3 compresses the back because the effect of friction, make unclamp clamp nut 1 after, bearing 3 is difficult to take off from axle.Need be with beaing bearing 3 or other complicated method is taken off bearing 3, so just may make main shaft 4 because of beaing or unbalance stress damages, cause the damage waste of workpiece, be unfavorable for the control of cost.
Summary of the invention
The purpose of this utility model provides a kind of easy to use, quick, the practical milling head, the boring head main shaft that make things convenient for the dismounting of main shaft upper bearing (metal).
The technical solution of the utility model is: bearing is housed on the main shaft, the main shaft of bearing both sides is provided with screw thread, the clamp nut that is used to compress bearing is housed on the screw thread of main shaft miner diameter end, the dismounting nut that is used to dismantle bearing is housed on the screw thread of main shaft bigger diameter end.
Between described clamp nut and the bearing packing ring is arranged.
Described dismounting nut is more than one.
When the damage of bearings on the main shaft need be pulled down bearing, rotate the dismounting nut, the dismounting nut pushes up with main shaft bearing to the displacement of main shaft miner diameter end mutually along the screw thread of main shaft, get loose until main shaft bearing, this mode is stressed evenly, convenient disassembly does not just need to beat main shaft bearing or uses other complicated method to take off bearing.The utility model makes things convenient for the dismounting of milling head, boring head main shaft bearing, and is easy to use, quick, practical.
Description of drawings
The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.
Fig. 1 is the structural representation of existing milling head, boring head main shaft.
Fig. 2 is a structural representation of the present utility model.
Among the figure, 1, clamp nut, 2, packing ring, 3, bearing, 4, main shaft, 5, the dismounting nut.
The specific embodiment
Among Fig. 2, bearing 3 is contained on the main shaft 4, and packing ring 2 is close to bearing 3, and clamp nut 1 is realized packing washer 2 by the screw thread on the relevant position on the main shaft 4, thereby compresses bearing 3.On main shaft 4 bigger diameter ends of bearing 3 one sides screw thread is arranged, dismounting nut 5 is loaded on the screw thread of main shaft 4 bigger diameter ends and is positioned at a side of main shaft bearing 3.Dismounting nut 5 fits with bearing 3 on main shaft 4 respective threads.When bearing 3 damages need be pulled down, unclamp clamp nut 1, take out clamp nut 1 and packing ring 2, rotate dismounting nut 5 and come apical axis to hold 3, get loose until bearing 3, so just do not need to beat main shaft bearing 3 to take off main shaft bearing 3.The quantity of dismounting nut 5 is one or more.
Claims (3)
1. a milling head, boring head main shaft, it is characterized in that: bearing (3) is housed on the main shaft (4), the main shaft (4) of bearing (3) both sides is provided with screw thread, the clamp nut (1) that is used to compress bearing (3) is housed on the screw thread of main shaft (4) miner diameter end, the dismounting nut (5) that is used to dismantle bearing (3) is housed on the screw thread of main shaft (4) bigger diameter end.
2. milling head according to claim 1, boring head main shaft is characterized in that: between described clamp nut (1) and the bearing (3) packing ring (2) is arranged.
3. milling head according to claim 1, boring head main shaft is characterized in that: described dismounting nut (5) is more than one.
