Detailed description of the invention
Below in conjunction with accompanying drawing, further describe the detailed description of the invention of this patent.
As Fig. 1, 2, shown in 3, cylindrical product 1 in this patent is the cylinder barred body of two parallel end faces, this device, comprise clamp shaft, clamping fixture seat and positioner 2, described clamp shaft comprises left clamp shaft 3 and the right clamp shaft 4 of coaxial setting, described left clamp shaft 3 comprises sandwich 31 and thimble 32, described right clamp shaft 4 includes sandwich 41 and thimble 42, described sandwich is coaxially connected with thimble, and described thimble and sandwich do not link, be provided with between the sandwich of described left clamp shaft 3 and the sandwich of right clamp shaft 4 mate with cylindrical product length clamp space, described clamping fixture seat comprises left clamping fixture seat 6 and right clamping fixture seat 7, the thimble of described left clamp shaft 3 is arranged in left clamping fixture seat 6, the thimble of described right clamp shaft 4 is arranged in right clamping fixture seat 7, described left clamping fixture seat 6 is connected with the rotating mechanism of grinding machine left clamping fixture seat 6 can be driven to rotate, described right clamping fixture seat 7 to be connected with the pushing mechanism of grinding machine by holder 8 right clamping fixture seat 7 can be driven to move axially along right clamp shaft, the pushing mechanism of described grinding machine comprises cylinder and plunger tip, described cylinder drives plunger tip to move, described plunger tip is connected with holder 8, described positioner comprises centering chuck 21 and external lock facing 22, screw thread is provided with vertically outside described left clamping fixture seat and right clamping fixture seat, described centering chuck is sleeved on clamping fixture seat, one end spinning is on the screw thread of clamping fixture seat, the other end is provided with locating detent 221, the end of described locating detent 221 be provided be greater than cylindrical product diameter and with the circular open of clamp shaft coaxial core, described locating detent 221 is made up of the elastic strip that many are axially laid, spacing is provided with between described elastic strip, the lateral surface of described locating detent 221 is inclined-plane, screw thread is provided with vertically outside described centering chuck, described external lock facing 22 is sleeved on outside described centering chuck, and one end spinning of external lock facing 22 is on described centering chuck, the other end compresses the lateral surface of locating detent 221, external lock facing 22 and locating detent 221 contact surface are the inclined-plane with locating detent slopes which match, like this when described external lock facing 22 is to a sideway swivel, under the effect on two inclined-planes, locating detent tightens up by described external lock facing 22, because locating detent is made up of elastic strip, therefore after external lock facing 22 is locked, the circular open of locating detent shrinks the diameter being less than cylindrical product 1, when described external lock facing rotates to opposite side, then locating detent unclamps, in the present embodiment, the sandwich 31 of described left clamp shaft 3 is provided with flange collar 311, described flange collar 311 is provided with multiple double wedge 312, between the position of double wedge 312 and the elastic strip of locating detent 221, gap matches, when chuck 21 of feeling relieved is tightened on left on left clamping fixture seat, the centering locating detent 221 of chuck 21 engages with the double wedge 312 of sandwich 31, centering chuck 21 links with sandwich 31, thus left clamping fixture seat drives sandwich 31 to rotate, when chuck 21 of feeling relieved positions to dextrorotation cylindrical product 1, the locating detent 221 of centering chuck 21 departs from the double wedge 312 of sandwich 31, thus remove interlock, prevent from surprisingly occurring when locating.
During work: first cylindrical product is placed between left clamp shaft and right clamp shaft, then cylinder is started, right clamp shaft is driven to move, the dynamics now clamped only need ensure that cylindrical product does not drop, then the centering chuck in moving positioning device, locating detent is sleeved on the outside of cylindrical product, then external lock facing is rotated, locating detent is tightened up, due to circular open and the clamp shaft coaxial core of locating detent, in the circular open contraction process of locating detent, cylindrical product will be driven to finely tune, finally make the circular open coaxial core of cylindrical product and locating detent, thus reach the effect of location, now restart cylinder, cylindrical product is fastening, finally unclamp external lock facing, to feel relieved chuck return.Drive left clamping fixture seat to rotate at the rotating mechanism by grinding machine, thus drive cylindrical product to rotate, process in grinding machine, after processing, just can loose unloading product with contrary operation.
