Description
Technical field
The utility model relates to clamping device technical field, is specifically related to a kind of automatically centering fixture of right boring cylinder cover inner hole.
Background technology
The fixture of tradition right boring cylinder cover inner hole, it, using the face of cylinder of outside diameter and end face as positioning datum, is pressed on small end face by axial force and clamps, this locate mode, what bring is improve machining accuracy by corresponding for less demanding position, adds processing cost.
Utility model content
It is low that technical problem to be solved in the utility model is to provide a kind of cost, processes the automatically centering fixture of simple right boring cylinder cover inner hole.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of automatically centering fixture of right boring cylinder cover inner hole, comprise cylindrical sleeve, cylinder cone and bearing, described cylindrical sleeve and cylinder cone are located at the two ends of bearing, and described bearing is connected with slippage bracket, and described slippage bracket is connected with screw, described screw is connected with leading screw, described leading screw is connected with collet, and described leading screw one end is connected with spanner, and the other end is provided with nut.
On such scheme basis preferably, described cylindrical sleeve is connected with plate.
On such scheme basis preferably, be articulated manner between described collet and leading screw.
The beneficial effect that the utility model compared with prior art has is: cylinder sleeve is put into fixture, insert plate, pull spanner to rotate to a direction, leading screw end face promotes collet with axial force and moves to left, under the effect of tapered sleeve, reduce to center, realize self-centering, when collet and cylinder jacket external diameter are close to gapless, spanner is exerted oneself again, screw mandrel reaction is on screw, now active force will pull slippage bracket to move to right, be pressed on the large end end face of cylinder jacket by plate, cylinder jacket end face is just close on the end face of cylindrical sleeve, axial location also clamps, when the facet on slippage bracket slides onto limited on cylinder cone end face, under leading screw effect, collet is pulled to throw off in tapered sleeve, cylinder sleeve small end face is relaxed, at this moment plate can be extracted, take out the cylinder sleeve that processes and exit boring cutter, reduce machining accuracy, decrease processing cost.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Number in the figure is: 1-plate, 2-cylindrical sleeve, 3-slippage bracket, 4-bearing, and 5-cylinder is bored, 6-nut, 7-screw, 8-collet, 9-leading screw, 10-spanner.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is only the utility model for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Known with reference to Fig. 1, a kind of automatically centering fixture of right boring cylinder cover inner hole, comprise cylindrical sleeve 2, cylinder cone 5 and bearing 4, described cylindrical sleeve 2 and cylinder cone 5 are located at the two ends of bearing 4, and described bearing 4 is connected with slippage bracket 3, and described slippage bracket 3 is connected with screw 7, described screw 7 is connected with leading screw 9, described leading screw 9 is connected with collet 8, and described leading screw 9 one end is connected with spanner 10, and the other end is provided with nut 6.
Further, described cylindrical sleeve 2 is connected with plate 1.
Further, be articulated manner between described collet 8 and leading screw 9.
Cylinder sleeve is put into fixture, insert plate 1, pull spanner 10 to rotate to a direction, leading screw 9 end face promotes collet 8 with axial force and moves to left, under the effect of tapered sleeve, reduce to center, realize self-centering, when collet 8 and cylinder jacket external diameter are close to gapless, spanner 10 is exerted oneself again, screw mandrel 9 reaction is on screw 7, now active force will pull slippage bracket 3 to move to right, be pressed on the large end end face of cylinder jacket by plate 1, cylinder jacket end face is just close on the end face of cylindrical sleeve 2, axial location also clamps, when the facet on slippage bracket 3 slide onto cylinder bore limited on 5 end faces time, under leading screw 9 acts on, collet 8 is pulled to throw off in tapered sleeve, cylinder sleeve small end face is relaxed, at this moment plate can be extracted, take out the cylinder sleeve that processes and exit boring cutter, reduce machining accuracy, decrease processing cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
