On the other hand, the unloading position A2 of workpiece W is positioned at the position adjacent with the ora terminalis of the rotation R side of guide table under outlet side 23, and the leading section of the rod member 14a of above-mentioned workpiece catching device 14 is positioned at the below of above-mentioned unloading position A2.Namely, when the isothrausmatic workpiece W of the similar piston ring of grinding, the workpiece W that the ora terminalis of guide table 23 is discharged from outlet side is accepted at unloading position A by the front end of rod member 14a, utilizes the inclination towards front lower place of rod member 14a automatically forwards slide and be kept.
Under entrance side, the below of guide table 21 is configured with the base end part 30a of the center 03 of the " loaded " position A1 swing arm 30 that is oscillation center, this swing arm 30 passes through the rotating shaft core 02 of circular table 11 from base end part 30a, is supported to rotatable at leading section 30b by above-mentioned circular table rotating shaft 12.
The front of the leading section 30b of swing arm 30 is configured with the crank-type swing driving mechanism 31 for making swing arm 30 swing, and the output connecting rod 32 of this crank-type swing driving mechanism 31 connects to free to rotate by connecting pin 34 and the front end face of the leading section 30b of swing arm 30.
(circular table of workpiece table device 10 rotary configured and swing structure)
In Fig. 3, the base end part 30a of swing arm 30 is supported to by upper and lower pair of bearings 37 can freely swings around swinging axle core 03 by the swing fulcrum 36 be vertically fixed on table device supporting station 7.
The leading section 30b of swing arm 30 is formed with cylindrical portion outstanding upward, circular table rotating shaft 12 is supported to rotatable by metal (upper 41 by the inner peripheral surface of this cylindrical portion.The bottom of circular table rotating shaft 12 links with the output shaft 44a of the circular table rotation drive motor 44 being installed on swing arm 30 bottom.The upper end of circular table rotating shaft 12 is connected with discoideus circular table mounting bracket 47, and the circular table 11 fastened plectane 48 be placed on this mounting bracket 47 is fastening from top.
The lower surface in the portion foremost of swing arm 30 comprises can free rolling supporting roller 50, and this supporting roller 50 is positioned on the rail bar 51 be located on table device supporting station 7, along with the swing of swing arm 30 is rolled on rail bar 51.
Fig. 4 represents the detailed construction of crank-type swing driving mechanism 31, and crank-type swing driving mechanism 31 comprises: gearmotor 61, and it is arranged on is located on the erecting bed 60 of table device supporting station 7; Crank arm 63, the upper end of the output shaft 61a of itself and said gear drive motor 61 is affixed; And above-mentioned connecting rod 32, it is linked rotatably by the leading section of pin 62 with above-mentioned crank arm 63, crank-type swing driving mechanism 31 is by the rotation of the output shaft 61a of gearmotor 61, utilize crank arm 63 that the pin 62 of connecting rod 32 is rotated around output shaft core 04, and by connecting rod 32, swing arm 30 is swung.Connecting rod 32 midway has screwed joint part 32a, can regulate length in turnbuckle formula ground by this.That is, swing starting position and end position by regulating the length of connecting rod 32 can change swing arm 30.In addition, by regulating the length of crank arm 63 or utilizing elongated hole or multiple pin-and-hole to regulate the position of the pin 62 of connecting rod 32 leading section, adjustment pin 62 departs from the core shift amount of gearmotor output shaft 61a, can regulate the oscillating quantity (amplitude) of swing arm 30 thus.
Fig. 5 show in detail the planar configuration of swing driving mechanism 31, and above-mentioned supporting roller 50 is separated with interval and arranges a pair on swaying direction B1, B2, and the portion foremost of the swing arm 30 between supporting roller 50 is provided with the projection 70 of swing position detection.On the other hand, the upper non-contact switch 72 detected every spaced a pair swing position of swaying direction B1, B2 is configured to relative with the face foremost of swing arm 30, close with each non-contact switch 72 by above-mentioned projection 70, the swing starting position of wobble detection arm 30 can be distinguished and swing end position.
(effect)
(1) in Fig. 2, on " loaded " position A1, heap is loaded with many thin workpiece (such as the piston ring etc. of 0.5mm ~ 1.0mm thickness) W, and it is locking by workpiece locking wall 13a, under this state, circular table 11 is rotated along arrow R direction around circular table rotating shaft core 02, in addition, utilize crank-type swing driving mechanism 31, swing arm 30 is swung along arrow B 1, B2 direction around swinging axle core 03.
(2) by the rotation of circular table 11, when workpiece retaining hole 18 arrives " loaded " position A1, the workpiece W of lowermost position is fed into workpiece retaining hole 18.The workpiece W kept by workpiece retaining hole 18 is by the gap on guide table under entrance side 21 and entrance side between guide plate 22, the position of above-below direction and the gap of two emery wheels 2 are as one man directed to, and insert between two emery wheels 2, utilize the both ends of the surface up and down of upper and lower two emery wheel 2 plane lapping workpiece W.In this grinding step, because circular table 11 rotates around circular table rotating shaft core 02 as mentioned above, and swing around swinging axle core 03, therefore, the carrying track of the workpiece W in workpiece retaining hole 18 is not simple arc-shaped, but similar sinuous carrying track in horizontal direction, by between two emery wheels 2.Therefore, even if long-time use also can reduce the generation of eccentric wear, high plane lapping precision is ensured.
(3) after grinding, the workpiece W discharged to workpiece outlet side is first by guide table under outlet side 23 and outlet side between guide plate 24, from outlet side, the ora terminalis of the direction of rotation R side of guide table 23 falls to being released to unloading position A2, accepted by the rod member 14a of workpiece catching device 14, forwards slide and be kept.
(4) finished work W be discharged after workpiece retaining hole 18 again move to " loaded " position A1, and be supplied to unprocessed workpiece W.
In present embodiment, because the swinging axle core 03 of swing arm 30 is consistent with the center of " loaded " position A1, so even if swing arm 30 swings, " loaded " position also can not change, workpiece retaining hole 18 must by fixing " loaded " position A1.Therefore, as loading attachment 13, only merely locking for workpiece wall 13a need be fixed on a position, can simple structure be adopted.
(other embodiments)
(1) above-mentioned embodiment is applied to the vertical duplex head surface grinder that grinding tool rotating shaft core vertically arranges, but also can be applicable to the Horizontal double-headed surface grinding machine of grinding tool rotating shaft core level arranging.
