Abstract
The utility model discloses a linear groove grinding head mechanism of an inner hole wall. The mechanism comprises high speed motors, and motor shafts connected by a shaft coupler, wherein one end of the shaft coupler is connected with a bevel gear shaft; a gear is arranged on the bevel gear shaft; the bevel gear shaft is fixed in a shaft hole of a grinding head seat by a bearing; the gear is fixed on the shaft by the bearing and mounted in the shaft hole of the grinding head seat; the bearing is positioned in an inner hole of a grinding wheel and on a grinding wheel spindle; one end of the grinding wheel spindle is mounted in the shaft hole of the grinding head seat, and the other end is arranged in the shaft hole of a cover board; the cover board is fixed at the side surface of the grinding head seat by a bolt; the linear velocity of the grinding wheel is 45 m/s; and an included angle between the axis of the grinding wheel and the axis of a work piece hole is 90 DEG. The mechanism can grind the linear groove on the inner hole wall at high precision in cooperation with the feed movement of the current machine tool; compared with former processing methods such as broaching, slotting and linear cutting, and the like, the precision and the roughness are improved obviously; meanwhile, the grinding wheel can be shaped online thus effectively reducing processing cost under different conditions, such as special form, small amount and quenched parts, etc.
Description
Technical field:
The utility model relates to inner hole wall straight-line groove grinding head mechanism, is specially adapted to the processing of grindings such as inner hole wall straight-line groove such as internal keyway, the axial raceway in linear bearing outer ring and internal gear teeth groove.
Background technology:
The processing of existing inner hole wall straight-line groove has broaching, slotting, line cutting etc. usually; Broaching and slotting need be equipped with special-purpose forming tool, use different cutters for different shape needs, and process for small lot; The cost input of cutter is very high; For in enormous quantities, along with the wearing and tearing of cutter, machining accuracy can reduce gradually.In addition, broaching and slotting are difficult to guarantee the positional precision (particularly concentricity) of groove relative opening, are difficult to the workpiece after hardening is processed.Roughness is the highest at 0.8 μ m under the specified conditions of broaching, and general roughness is all below 1.6 μ m.For that harden or less in batches workpiece inner hole wall straight-line groove processing, though can adopt the mode of line cutting, this kind processing mode only limits to require not too high occasion to use to the precision and the roughness of groove.Therefore, for the increasingly high inner hole wall straight-line groove of required precision, the groove at particularly lead position and transmission position, how carrying out more high-precision processing is the problem that presses for solution.
Summary of the invention:
The task of the utility model is to propose a kind of raising straight-line groove surfacing roughness; And can satisfy the inner hole wall straight-line groove grinding head mechanism of small dimension high precision ball spline housing, linear bearing, internal gear parts processing; The task of the utility model is done in such a way that it comprises that high-speed electric expreess locomotive, motor shaft connect through shaft coupling, is characterized in that: be connected with bevel gear shaft on the end of shaft coupling; Gear is arranged on the bevel gear shaft; In the axis hole of bistrique seat, gear, is equipped with bearing and is contained on the grinding wheel spindle in the axis hole that is contained in the bistrique seat on the axle through bearing fixing bevel gear shaft in the endoporus of emery wheel through bearing fixing; One end of grinding wheel spindle is contained in the axis hole of bistrique seat, and the other end is contained in the axis hole of cover plate.Cover plate is fixed on the side of bistrique seat through screw.The linear velocity of emery wheel reaches 45m/s, and emery wheel axis and workpiece hole axis are 90 °.The utlity model has following effect; The utility model cooperates the feed motion of existing lathe; Can realize the high-precision grinding of inner hole wall straight-line groove, processing methods such as broaching more in the past, slotting and line cutting, precision and roughness significantly improve; And because emery wheel can online correction of the flank shape, effectively reduce special shape, small lot, the processing cost of the various situation such as other part of hardening.
Description of drawings:
Fig. 1 is the external structure sketch map of the utility model; Fig. 2 is the A-A cut-away view of Fig. 1.
Drawing explanation: 1, emery wheel, 2, grinding wheel spindle, 3, cover plate, 4, bevel gear shaft, 5, shaft coupling, 6 gears, 7, axle, 8, bearing, 9, adjusting pad, 10, the bistrique seat, 11, high-speed electric expreess locomotive.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, the motor shaft on the high-speed electric expreess locomotive 11 connects with shaft coupling 5, is connected with bevel gear shaft 4 on the other end of shaft coupling; Bevel gear shaft 4 meshes with gear 6 in the axis hole of bistrique through bearing fixing, and gear 6 on the axle 7 in the axis hole of bistrique seat 10, is equipped with bearing 8 through bearing fixing in the emery wheel endoporus; Bearing 8 is contained on the grinding wheel spindle 2, the tooth engagement on gear 6 and the emery wheel 1, and grinding wheel spindle 2 one ends are contained in the axis hole of bistrique seat 10; The other end is contained in the axis hole of cover plate 3, and cover plate is fixed on the side of bistrique seat 10 through screw, and the power of grinding head mechanism is provided by high-speed electric expreess locomotive 11; Drive bevel gear shaft 4 through shaft coupling 5; Bevel gear shaft 4 is passed to gear 6, and gear 6 transferring power are to emery wheel 1, thereby makes emery wheel 1 carry out grinding work piece; But the grinding head mechanism action realizes the straight-line groove on the grinding inner hole wall, keyway and internal gear etc. by the feed motion on the existing lathe.
