Abstract
The utility model discloses a limiting buffer mechanism for a machine tool. The limiting buffer mechanism for the machine tool is installed in a base and comprises an elastic body, two clamping boards, a pre-tightening pulling rod, a pre-tightening adjusting nut and an anti-rebounding pressing board. The two clamping boards are located at the two ends of the elastic body respectively. A hole is formed in the middle of the elastic body. Holes are formed in the middle portions of the two clamping boards. One end of the pre-tightening pulling rod is provided with a step and the other end of the pre-tightening pulling rod is provided with threads. One end of the pre-tightening pulling rod penetrates through the holes of the clamping boards and the hole of the elastic body and is installed through the match with internal threads at the inner side of the pre-tightening adjusting nut. The other end of the pre-tightening pulling rod penetrates through a hole in the anti-rebounding pressing board. The anti-rebounding pressing board is connected to the base and used for fixing the elastic body. The pre-tightening adjusting nut is rotated and acts on the clamping boards so that the deformation amount of the elastic body can be adjusted. According to the limiting buffer mechanism for the machine tool, large pre-pressure is generated through pre-deformation of the elastic body, so that the buffer capacity is improved in collision, large impact force can be absorbed under the condition of a relative small structure, and therefore the ideal buffer effect is obtained.
Description
Technical field
The utility model relates to mechanical damping field, relates in particular to a kind of lathe limiting buffer mechanism.
Background technology
The limiting buffer mechanism adopting at present mostly in the industry is impulsive contact force and directly acts on elastomer, and impact resistance is not high, easily produces total travel resilience and causes secondary to destroy, and elastomer is fragile, can not meet the instructions for use that stability requirement high field is closed.
Utility model content
The purpose of this utility model is: in order to address the above problem, a kind of lathe simple in structure, easy to use limiting buffer mechanism is provided, utilize elastomeric predeformation to produce larger precompression, buffer capacity while improving collision, relatively under minor structure state, can absorb higher impulsive force, to obtain desirable buffering effect.
To achieve these goals, the technical solution of the utility model is:
One lathe limiting buffer mechanism, is installed in pedestal, comprises elastomer, two clamping plates, pretension pull bar, pretension adjusting nut and anti-rebound pressing plate; Two described clamping plate lay respectively at described elastomeric two ends; Porose in the middle of described elastomer; Porose in the middle of two described clamping plate; Described pretension pull bar one end is provided with step, and the other end is provided with screw thread; , through described clamping plate and elastomeric hole, install with the screw-internal thread fit of described pretension adjusting nut inner side described pretension pull bar one end; The described pretension pull bar other end is through the hole on described anti-rebound pressing plate; Described anti-rebound pressing plate is connected on described pedestal, fixing described elastomer; Act on clamping plate by rotation pretension adjusting nut and adjust elastomeric deflection.
Further, described pedestal is provided with mounting structure, comprises U shape groove, circular hole, installation base surface and screw thread is installed; Described clamping plate and elastomer are positioned in the middle of described U shape groove; Described pretension adjusting nut passes from described pedestal one mother rib lateral rotundum; Described anti-rebound pressing plate is fixed on described pedestal opposite side by screw.
The utility model is owing to having adopted above-mentioned technology, and the good effect that makes it compared with prior art to have is:
The utility model is owing to being provided with pretension pull bar through elastomer and clamping plate, and one end is connected in pretension adjusting nut, and the adjustable pretightning force size of pretension adjusting nut, makes same parts can be applicable to close different occasion and need not change elastomer; Component integration is installed on pedestal, makes the machine be configured to standalone module, facilitates the installation application of diverse location and safeguards; The utility model structural reliability is very high, and pretightning force retentivity is stable, and contingent collision does not directly act on elastomer, greatly improves the elastomer life-span.

Detailed description of the invention
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 and Fig. 2, a kind of lathe limiting buffer mechanism, is installed in pedestal 1, comprises elastomer 4, two clamping plates 3, pretension pull bar 6, pretension adjusting nut 2 and anti-rebound pressing plate 5; Two described clamping plate 3 lay respectively at the two ends of described elastomer 4; Porose in the middle of described elastomer 4; Porose in the middle of two described clamping plate 3; Described pretension pull bar 6 one end are provided with step, and the other end is provided with screw thread; , through described clamping plate 3 and elastomeric hole, install with the screw-internal thread fit of described pretension adjusting nut 2 inner sides described pretension pull bar 6 one end; Described pretension pull bar 6 other ends are through the hole on described anti-rebound pressing plate 5; Described anti-rebound pressing plate 5 is connected on described pedestal 1, fixing described elastomer 4; Act on clamping plate 3 and adjust the deflection of elastomer 4 by rotation pretension adjusting nut 2.
Preferably, described pedestal 1 is provided with mounting structure, comprises U shape groove, circular hole, installation base surface and screw thread is installed; Described clamping plate 3 and elastomer 4 are positioned in the middle of described U shape groove; Described pretension adjusting nut 2 passes from described pedestal 1 one mother rib lateral rotundums; Porose in the middle of anti-rebound pressing plate 5, can hold pretension pull bar 6 has step one end to pass freely through, and described anti-rebound pressing plate 5 is fixed on described pedestal 1 opposite side by screw.
Preferably, pretension pull bar 6 step ends adopt high-strength material, for bearing contingent collision.
In sum, the utility model is simple in structure, easy to use, utilizes elastomeric predeformation to produce larger precompression, and the buffer capacity while improving collision, relatively can absorb higher impulsive force under minor structure state, to obtain desirable buffering effect.
