Abstract
The utility model provides a diamond roller dresser, comprising a housing fixing device and a dressing slewer. The dressing slewer comprises a main shaft which is rotatingly disposed on the housing fixing device through a two-gear bearing and a bearing base. One end of the main shaft is connected to a belt pulley. The utility model is characterized in that the housing fixing device comprises a bearing and a housing; the main shaft is inlaid into a roller sleeve through an interference fit; the external diameter of the roller sleeve is larger than that of the bearing seat; the roller sleeve is disposed between two bearings; the diamond roller is disposed on the roller sleeve. As the two-gear bearings are adopted at two ends of the diamond roller, the carrying capability of the bearings at two sides are even, the service lifetime of the bearing is effectively prolonged, the rigidity of the grinding wheel during the dressing is enhanced, the dressing quality of the grinding wheel is improved, and the grinding property of the machine tool is ensured.
Description
Technical field
The utility model relates to the technical field of grinding machine components, is specially a kind of emery wheel trimmer.
Background technology
Existing emery wheel trimmer structure is seen Fig. 1, and belt pulley 1 drives main shaft 2 revolutions by flat key, makes the emery wheel 4 rotation trimming wheels that are contained in main shaft 2 right side axle heads, and bearing 3 is contained in the integral housing 5.Because emery wheel is overhung at the outside of bearing, the bearing of both sides bears uneven alternating force in turning course, and the life-span of bearing is shorter.In addition, owing to adopt cantilever to go out axle construction, rigidity is relatively poor when causing the emery wheel trimming wheel, thereby influences the grinding performance of lathe.
Summary of the invention
At the problems referred to above, the utility model provides a kind of emery wheel trimmer, and this emery wheel trimmer can make the bearing of both sides stressed even in turning course, and rigidity also improves greatly during trimming wheel, thereby guarantees the grinding performance of lathe.
Its technical scheme is such: a kind of emery wheel trimmer, it comprises housing fixture, finishing slewing equipment, described finishing slewing equipment comprises main shaft, described main shaft is rotatably installed on the housing fixture by two grades of bearings, bearing blocks, one end of described main shaft is connected with belt pulley, it is characterized in that: described housing fixture comprises bearing, housing, described main shaft interference fit is bumped into roller housing, the external diameter of described roller housing is greater than the external diameter of described bearing block, described roller housing is between two grades of bearings, and emery wheel is installed on the described roller housing.
It is further characterized in that: described case cover residence is stated main shaft and is connected with described bearing.
Because the utility model adopts two grades of bearing supportings at the emery wheel two ends; the bearing that makes both sides is stressed in turning course evenly effectively to improve bearing service life, and the rigidity when having increased trimming wheel; improve the crushing quality, thereby guarantee the grinding performance of lathe.
Description of drawings
Fig. 1 is existing emery wheel axle construction schematic diagram;
Fig. 2 is the structural representation of the utility model emery wheel trimmer.
The specific embodiment
See Fig. 2, the utility model emery wheel trimmer comprises housing fixture, finishing slewing equipment, the finishing slewing equipment comprises main shaft 4, main shaft 4 is by two grades of bearing 2-1,2-2, bearing block 7-1,7-2, be rotatably installed on the housing fixture, one end of main shaft 4 is connected with belt pulley 1, the housing fixture comprises bearing 6, housing 8, main shaft 4 interference fit are bumped into roller housing 5, the external diameter of roller housing 5 is greater than the external diameter of bearing block 7-1,7-2, roller housing 5 is between two grades of bearing 2-1,2-2, and emery wheel 3 is installed on the roller housing 5.Housing 8 covers main shaft 4 and is connected with bearing 6.
Main shaft 4 is by roller housing 5 bearings at both ends 2-1,2-2, bearing block 7-1,7-2 supporting realizes rotating, bearing 6 and housing 8 are taken apart back emery wheel 3 can be installed on the roller housing 5 easily, belt pulley 1 drives main shaft 4, roller housing 5 by flat key, makes emery wheel 3 rotations realize the crushing action.
The utility model is owing to adopt two grades of bearing 2-1,2-2 to support at emery wheel 3 two ends; the bearing that makes both sides in turning course stressed evenly, and the rigidity when having increased trimming wheel can effectively improve bearing service life; improve the crushing quality, thereby guarantee the grinding performance of lathe.
Claims (2)
1. emery wheel trimmer, it comprises the housing fixture, the finishing slewing equipment, described finishing slewing equipment comprises main shaft, described main shaft is by two grades of bearings, bearing block is rotatably installed on the housing fixture, one end of described main shaft is connected with belt pulley, it is characterized in that: described housing fixture comprises pressing plate, housing, described main shaft interference fit is bumped into roller housing, the external diameter of described roller housing is greater than the external diameter of described bearing block, described roller housing is positioned at the centre position of two grades of bearings, emery wheel is installed on the described roller housing, and described main shaft is installed on the described housing by pressing plate and described bearing block.
