Description

The trimmer of bearing inner race ditch CBN emery wheel

Technical field

The present invention relates to the technical field of structures of grinding machine, be specially the trimmer of bearing inner race ditch CBN emery wheel.

Background technology

Existing bearing inner ring ditch CBN dresser; All use shaping emery wheel finishing CBN emery wheel, the influence of the emery wheel precision that is shaped on the one hand has irreversibility; The variation of bearing inner race ditch R on the other hand; Can only could realize that its operation is wasted time and energy, and grinding accuracy is poor through changing emery wheel; And it can't grinding bearing inner ring ditch CBN emery wheel.

Summary of the invention

To the problems referred to above, the invention provides the trimmer of bearing inner race ditch CBN emery wheel, it makes versatility good, it is time saving and energy saving to operate, and grinding accuracy is high, but and its grinding bearing inner ring ditch CBN emery wheel.

The trimmer of bearing inner race ditch CBN emery wheel, its technical scheme is such: it comprises fork, base, angling cylinder, the two ends that are supported at both ends in said base of said fork are inboard; Said angling cylinder is supported on an end of said base, and the drive end of said angling cylinder connects an end of said fork, and the centre position of said fork is provided with the grinding structure; Said grinding structure is towards the CBN emery wheel; It is characterized in that: said grinding structure specifically comprises Buddha's warrior attendant dish, electric main shaft, dial, and the output of said electric main shaft is set with said Buddha's warrior attendant dish, and gland is loaded on said electric main shaft outer face through the screw fastening cover; Be furnished with said Buddha's warrior attendant dish in said gland, the formed cavity in electric main shaft outer face; The centre position of said fork is provided with the gathering sill that can move radially along the CBN emery wheel, and the outer face of said electric main shaft, Buddha's warrior attendant dish, gland are positioned at said gathering sill, and said gland is fastened with drive nut away from an end of said CBN emery wheel; Screw flight connects said drive nut; Said screw rod is parallel to the direction of feed of said gathering sill, and said dial is connected with screw rod through fastening nail, and said dial is positioned at the tail end position of the corresponding fork of said gathering sill; The front end of said dial is provided with baffle plate, and said baffle plate is fastenedly connected the tail end of the corresponding fork of said gathering sill.

It is further characterized in that: between said baffle plate and the said drive nut spring is housed, said spring housing is loaded on the outer ring surface of said screw rod.

After adopting structure of the present invention, the Buddha's warrior attendant dish is grinding bearing inner ring ditch on the CBN emery wheel directly, in addition; Through rotary dial, and then drive the screw rod rotation, drive nut is done straight-line feed; Thereby promote gland along the gathering sill rectilinear motion, and then accomplished Buddha's warrior attendant dish CBN emery wheel and move radially, it makes versatility good; It is time saving and energy saving to operate, and grinding accuracy is high.

The specific embodiment

See Fig. 1, Fig. 2, Fig. 3, it comprises fork 1, base 2, angling cylinder 3, and the two ends that are supported at both ends in base 2 of fork 1 are inboard; Angling cylinder 3 is supported on an end of base 2, and the drive end of angling cylinder 3 connects an end of fork 1, and the centre position of fork 1 is provided with the grinding structure; The grinding structure is towards CBN emery wheel 4, and the grinding structure specifically comprises Buddha's warrior attendant dish 5, electric main shaft 6, dial 7, and the output of electric main shaft 6 is set with Buddha's warrior attendant dish 5, also locks through locking nut 19; Gland 8 is loaded on electric main shaft outer face 9 through the screw fastening cover, is furnished with Buddha's warrior attendant dish 5 in gland 8, the electric main shaft outer face 9 formed cavitys, and the centre position of fork 1 is provided with the gathering sill 10 that can move radially (i.e. directions X among the figure) along CBN emery wheel 4; Electricity main shaft outer face 9, Buddha's warrior attendant dish 5, gland 8 are positioned at gathering sill 10; Briquetting 11 connects said fork 1 through nut 12, screw 13, and briquetting 11 is positioned at the outside of gland 8, and gland 8 is fastened with drive nut 14 away from an end of CBN emery wheel 4; Screw rod 15 drive nut 14 that is threaded; Screw rod 15 is parallel to the direction of feed of gathering sill 10, and dial 7 is connected with screw rod 15 through fastening nail 16, and dial 7 is positioned at the tail end position of the fork 1 of gathering sill 10 correspondences; The front end of dial 7 is provided with baffle plate 17, and baffle plate 17 is fastenedly connected the tail end of gathering sill 10 pairing forks 1.Between baffle plate 17 and the drive nut 14 spring 18 is housed, spring 18 is set in the outer ring surface of screw rod 15.Spring 18 mainly works the crack effect that disappears.

Its operation principle is following: rotary dial 7 makes screw rod 15 move through screw drive drive nut 14, thereby realizes the variation of H value among the figure, and the size of the radius R of CBN emery wheel 4 is determined by the H value.
