Abstract
The utility model relates to a hydraulic bulge cutting tool clamp. An annular sealed oil cavity is arranged between a clamp main body and the bulging wall of a clamp holding hole, the oil cavity is filled with special hydraulic pressure oil inside, oil pressure is evenly transferred to each part of the sealed oil cavity; the clamp main body is provided with a hole which is communicated with an oil channel of the oil cavity, one end of the hole is connected with a forcing bolt for matching, the bulging wall of the clamp holding hole has good elasticity and generates the required swell increment when the oil pressure reaches the setting value. The inner wall of the oil cavity evenly and symmetrically bulges towards the radial direction, so as to tight a cutting tool. When the forcing bolt is loosened, the oil pressure inside the oil cavity falls, and the inner wall of the clamp holding hole restores the original diameter under the action of elastic restoring force to loosen the cutting tool. The hydraulic bulge cutting tool clamp has the benefit effects that the clamping gyration precision is less than 0.3 microns; the repeated clamping precision is less than 0.2 microns; the clamp force is stable and reliable; a very high torque can be transferred, a clamping system has a totally enclosed structure, has no abrasion and wears well, and the assembly and the disassembly of the cutting tool are simple and convenient.
Description
Technical field
The utility model relates to a kind of hydraulic buckling type tool mounting, belongs to mechanical field.
Background technology
Existing hydraulic buckling type tool mounting is widely used in manufacturings such as automobile, machinery, is applicable to machining center, clamping drilling bit, reamer, milling cutter etc. on the high accuracy boring machine, and existing structure can not satisfy high-precision requirement.
Summary of the invention
In order to overcome the deficiency of prior art structure, the utility model provides a kind of hydraulic buckling type tool mounting.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of hydraulic buckling type tool mounting, jig main body and clamping hole expansion wall between the oil pocket of a ring seal is arranged, be full of specific hydraulic fluid in the oil pocket, oil pressure is delivered to equably each part of seal oil chamber; Porose on the jig main body, the hole has oil circuit to communicate with oil pocket, and an end in hole is connected with pressurization bolt and is complementary, and the expansion wall in clamping hole has good elasticity, produces the swell increment that needs when oil pressure reaches setting value.
When tighten pressurization bolt with inner hexagon spanner, when improving the oil pressure in the oil pocket, each part in the oil closed cavity all can be subjected to identical pressure, and the even and symmetrical geocentric vertical direction of inwall of oil pocket is expanded and the tight cutter that rises in value; When unclamping pressurization bolt, oil pressure falls after rise in the oil pocket, and clamping hole inwall is returned to green diameter and loosening cutter under the effect of elastic-restoring force.
The beneficial effects of the utility model; The hydraulic buckling type tool mounting has following premium properties; The clamping rotating accuracy is less than 0.3 μ m; Repeat clamping accuracy less than 0.2 μ m; Clamping force is reliable and stable; Can transmit very high moment of torsion; Clamping system has full-closed structure, does not have wearing and tearing, and is durable in use; The loading and unloading cutter is simple and convenient.
The hydraulic buckling type tool mounting need have under the situation of cooling fluid and uses, and the optimum working temperature scope is 20 ℃ to 50 ℃.10 ℃ of minimum operating temperatures, maximum operating temperature are 80 ℃.When carrying out the big dried machining of long processing time, cutting output,, therefore should not use the hydraulic buckling type tool mounting because operating temperature surpasses the temperature range that the tool mounting main body is allowed easily.
The hydraulic buckling type tool mounting can provide the precision of machining part and the surface quality of workpiece effectively, significantly improves the stress of cutter in machining, significantly improves the service life of cutter.
Description of drawings
Below in conjunction with drawings and Examples utility model is further specified.
Fig. 1 is the utility model schematic diagram.
The specific embodiment
Embodiment 1: as shown in Figure 1,
The structure of hydraulic buckling type tool mounting as shown in the figure, jig main body 8 and clamping hole 4 expansion wall 3 between the oil pocket 2 of a ring seal is arranged, be full of specific hydraulic fluid in the oil pocket 2, oil pressure can be delivered to equably each part of the oil pocket 2 of sealing.On the jig main body 8 porose 6, hole 6 has oil circuit 7 to communicate with oil pocket 2, and an end in hole 6 is connected with pressurization bolt 1 and is complementary, and the expansion wall in clamping hole 4 is set through accurate Calculation, have good elasticity, can when oil pressure reaches setting value, produce the swell increment that needs.Cutter 5 is packed in the clamping hole 4, when tighten pressurization bolt 1 with inner hexagon spanner, when improving the oil pressure in the oil pocket, each part in the oil pocket 2 of sealing all can be subjected to identical pressure, and the even and symmetrical geocentric vertical direction of inwall of oil pocket 2 is expanded and the tight cutter 5 that rises in value; When unclamping pressurization bolt 1, oil pressure falls after rise in the oil pocket, and clamping hole inwall is returned to green diameter and loosening cutter 5 under the effect of elastic-restoring force.
