Abstract
A cylindrical grinding machine crystal centering clamp comprises two positioning supports and two supporting rods. The two supporting rods are provided with scale marks and disposed in the middles of the two positioning supports, heights of the supporting rods with scale marks can be adjusted, each positioning support is Y-shaped, a cylinder rod with a taper hole is arranged on the upper portion of each Y-shaped positioning support, the cylinder rods are engaged with outer circles of centers at two ends of the grinding machine, and two ends of a single crystal rod contact with the centers at two ends of the grinding machine. The cylindrical grinding machine crystal centering clamp has the advantages that the clamp can clamp crystal rods high efficiently, is accurate in centering and can not damage the grinding machine. In addition, the clamp has various specifications so as to be adaptable to crystals with different length and diameter internals.
Description
Technical field
Utility model relates to the semi-conducting material manufacture field, belongs to a kind of and is used in crystal on the cylindrical grinder to centre clamp.
Technical background
Because semi-conducting material belongs to hard brittle material, be not easy to its processing center hole, therefore, crystal is by clamping to grinding machine the time, how the center become to influence the key factor of working (machining) efficiency and crudy.At present, it often adopts amesdial to the center mode to the center mode, promptly crystal in advance clamping to grinding machine, measure the crystal change numerical value on same disc end to end with amesdial then, and knock crystal with rubber hammer, make the change value of amesdial be reduced to an acceptable numerical value and get final product.The method centering cardiac efficiency is low, and in the process of knocking the top precision of lathe is caused certain influence, and the time has been grown the damage that also can cause the headstock spindle bearing.
Summary of the invention
The purpose of this utility model provides a kind of cylindrical grinder crystal that is used in to centre clamp, these anchor clamps clamping crystal bar efficient height, accurately and can produce infringement to lathe to the center.
For achieving the above object, the utility model is taked following design:
A kind of cylindrical grinder crystal is to centre clamp, and it comprises: 2 locating supports, 2 poles that are positioned at the band scale at locating support middle part, the pole adjustable height of band scale.
Each locating support is " Y " type, and the top of " Y " type is the cylindrical rod of band taper hole, and cylindrical rod cooperates with the top cylindrical in lathe two, and the monocrystal rod two ends contact with lathe two is top.
Fixed bar, the motion bar, fixed bar and the motion bar that insert in the fixed bar are fixed with lock screw.
The utility model has the advantages that: clamping crystal bar efficient height, accurately and can not produce infringement, and plurality of specifications can be arranged to adapt to the crystal between different length, diameter region to lathe to the center.

The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: a kind of cylindrical grinder crystal comprises the cylindrical rod 1-1 of locating support 1, band taper hole to centre clamp.The pole 2,3 of band scale, wherein pole is made up of motion bar 4, fixed bar 6, lock screw 5 again.Motion bar inserts in the fixed bar, fixed bar and motion bar are fixed with lock screw.Have length scales on the motion bar 4, can be adjusted to arbitrary height and use lock screw 5 lockings.
Concrete operations are the crystal diameter ab that measure two distances 1 of anchor clamps in the crystal clamping process, two pole corresponding height h1, h2 promptly calculate difference in height by the diameter difference on the anchor clamps by calculating then, measure brilliant concrete length and select the anchor clamps of appropriate length for use, in clamping process, make locating support " Y " type structure by top periphery of real machine bed head frame and the top periphery of tail stock for machine tool, crystal bar is by real pole " Y " type structure simultaneously.Lock then that tail stock for machine tool is top to get final product.Finish crystal to center operations by two point location modes.
This principle to the center mode is: determine center line by two-point method, wherein top periphery of the lathe headstock and tailstock center periphery are constant, only need to regulate pole 2,3 to highly getting final product accordingly.Because crystal bar does not have center hole, therefore in clamping process, need to be used with the cylindrical rod 1-1 of taper hole.
Claims (3)
