Description
Technical field
The utility model relates to expansion core tensioning technique field, particularly a kind of tapered sleeve expansion core formula clamping device.
Background technology
Important foundation part in belt pulley machinery product.At present, in production, generally use dabber clamp to fix belt pulley, thereby complete machining small on belt pulley, dabber clamp is comprised of rigid central spindle, plain washer, these three parts of fishbolt, the cylindrical of clamping Shi Yi rigid central spindle is as positioning datum, by screw down clips jack panel clamping work pieces.Although the clamping belt that this dabber clamp can be more stable is taken turns, and completes the processing of aperture on belt pulley, when belt pulley size is larger, need larger rigid central spindle, exist rigid central spindle to manufacture the shortcomings such as tired energy, cost increase.
This dabber clamp need to be removed the locking of nut and workpiece could be taken out, and therefore needs expensive time and efforts belt pulley could be taken out, and causes the waste of manpower, has had a strong impact on production efficiency.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of simple in structure, cost is low, tension force is large tapered sleeve expansion core formula clamping device is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of tapered sleeve expansion core formula clamping device, it comprises workbench, inner conical drogue, pull bar, external conical sleeve, spring and cylinder, inner conical drogue at right angle setting is on workbench, inner conical drogue top is tapered, pull bar passes workbench and inner conical drogue perpendicular to workbench, pull bar bottom cover has spring, external conical sleeve is installed on pull bar, on external conical sleeve, be provided with opening, external conical sleeve is enclosed within on the taper surface of inner conical drogue, and cylinder is arranged on workbench below perpendicular to workbench.
Its one end of described spring is connected with pull bar bottom, and the other end of spring is fixed on workbench.
The piston rod of described cylinder be arranged at pull bar under.
On described external conical sleeve, be provided with 10 decile openings.
The utlity model has following advantage: (1) the utility model adopts external conical sleeve swelling clamping work pieces, larger-size belt pulley can be clamped fastening, have advantages of simple in structure, cost is low.(2) by spring, lock, pneumatic loosening device only has one, makes compact assembling structure, is convenient to the installation of combination drilling machine workbench.(3) piston rod protrudes upward, and pushing drawing rod moves up, thereby can comparatively fast, easier take out belt pulley, has improved production efficiency.

In figure, 1-workbench, 2-inner conical drogue, 3-pull bar, 4-external conical sleeve, 5-spring, 6-cylinder, 7-piston rod, 8-opening.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1 or 2, a kind of tapered sleeve expansion core formula clamping device, it comprises workbench 1, inner conical drogue 2, pull bar 3, external conical sleeve 4, spring 5 and cylinder 6, inner conical drogue 2 at right angle settings are on workbench 1, inner conical drogue 2 tops are tapered, pull bar 3 passes workbench 1 and inner conical drogue 2 perpendicular to workbench 1, pull bar 3 bottom covers have spring 5, external conical sleeve 4 is installed on pull bar 3, on external conical sleeve 4, be provided with opening 8, external conical sleeve 4 is enclosed within on the taper surface of inner conical drogue 2, and cylinder 6 is arranged on workbench 1 below perpendicular to workbench 1.
As Figure 1-4, pull bar 3 bottoms covers have spring 5, and spring 5 its one end are connected with pull bar 3 bottoms, and the other end of spring 5 is fixed on workbench 1, cylinder 6 its piston rods 7 be arranged at pull bar 3 under.On external conical sleeve 4, be provided with 10 decile openings 8.External conical sleeve 4 is placed in the centre bore of belt pulley, belt pulley is placed on inner conical drogue 2, when the piston rod 7 of cylinder 6 is during in retracted mode, external conical sleeve 4 is strained by spring 5 by pull bar 3, at this moment external conical sleeve 4 contacts with the conical surface of inner conical drogue 2, because the reason of external conical sleeve 4 upper sheds 8, it is large that the cylindrical of external conical sleeve 4 becomes, the centre bore of swelling belt pulley, thus belt pulley is fixed to clamp.
The course of work of the present utility model is as follows: first external conical sleeve 4 is placed in the centre bore of belt pulley, belt pulley is placed on inner conical drogue 2, again the piston rod of cylinder 67 is regained, spring 5 drives pull bar 3 to move down, and the external conical sleeve 4 being at this moment installed on pull bar 3 contacts with the conical surface of inner conical drogue 2, because the reason of external conical sleeve 4 upper sheds 8, it is large that the external diameter of external conical sleeve 4 becomes, the centre bore of swollen tight belt pulley, thus belt pulley is fixed to clamp, and rig floor just can bore aperture to belt pulley; After completing processing, the piston rod 7 of cylinder 6 stretches out, and piston rod 7 withstands pull bar 3 bottoms, and pull bar 3 moves up, and external conical sleeve 4 is separated with the conical surface of inner conical drogue 2, and the external diameter of external conical sleeve 4 diminishes, and at this moment can easily take out belt pulley.
