Description

A kind of quick prepressing device in the confined space
Technical field
The utility model and Diesel Engine Technique Field, and in particular to the quick prepressing device in a kind of confined space.
Background technique
Current big-and-middle diesel engine vibrates in use, noise is very big, common measure be using vibro-damping mount into Row vibration and noise reducing;The main body of the vibration isolation of vibro-damping mount is rubber shock absorber, since installation space is narrow, can only rely on external force at present Or the self gravity precompressed rubber shock absorber of diesel engine, so that rubber shock absorber is reached suitable decrement, low efficiency, and diesel oil Machine can make rubber shock absorber deflection be more than the failure that its maximum distortion ability causes vibration isolator in violent shake.
Utility model content
The purpose of this utility model is the quick prepressing device proposed in a kind of confined space, can quickly to rubber every The device that shakes carries out precompressed, and in diesel engine operational process, the deflection of rubber shock absorber can be effectively controlled.
The utility model is to complete above-mentioned purpose to adopt the following technical scheme that
A kind of quick prepressing device in the confined space, the quick prepressing device is arranged in recessed on rubber shock absorber In slot;The quick prepressing device has short stud, and the both ends of the short stud are respectively screw rod I, screw rod II; It is connected as one between the screw rod I, screw rod II by polished rod transition;The diameter of the polished rod is less than screw rod I, screw rod II Diameter;Screw rod I described in short stud is threadedly coupled with the screw hole of rubber shock absorber groove side;Described in short stud The outside wall surface of screw rod II has the external screw thread connecting with loop;With the tubular knot of step through-hole centered on the loop Structure;The step through-hole is up big and down small structure;The small diameter bore of step through-hole and the screw rod of bolt are used cooperatively; The large diameter hole of step through-hole and the nut kiss of bolt are matched;The top in step through-hole wall face has to be connected with screw rod II The internal screw thread connect;The nut of the bolt is located in the large diameter hole of step through-hole, and the screw rod of bolt stretches out described Step through-hole is threadedly coupled with the tapped through hole of the rubber shock absorber groove other side.
There are two groups of symmetrically arranged through-holes in the outside wall surface of the loop.
The bolt has nut and screw rod, and the top of the screw rod is polished rod, middle part is provided with for bolt fastening Hexahedron, lower part is to the threaded rod that is threadedly coupled with the tapped through hole.
The center of screw rod II described in short stud has the hexagonal hole to cooperate with allen wrench.
The utility model proposes a kind of confined space in quick prepressing device, be arranged in the groove of glue vibration isolator, By the cooperation of short stud, loop and bolt, quickly and effectively solve the problems, such as the precompressed of the rubber shock absorber useful space, And the stroke that rubber shock absorber is effectively controlled when diesel engine acutely shakes, improves reliability and the longevity of rubber shock absorber Life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of short stud in the utility model.
Fig. 3 is the structural schematic diagram of loop in the utility model.
Fig. 4 is the structural schematic diagram of bolt in the utility model.
In figure: 1, short stud, 1-1, screw rod I, 1-2, screw rod II, 1-3, polished rod, 2, loop, 3, bolt, 3-1, spiral shell Cap, 3-2, screw rod, 3-3, hexahedron, 4, rubber isolator.
Specific embodiment
The utility model is illustrated in the following with reference to the drawings and specific embodiments:
As shown in Figure 1, the quick prepressing device in a kind of confined space, the quick prepressing device setting rubber every In the groove to shake on device 4;The quick prepressing device has short stud 1, in conjunction with Fig. 2, the two of the short stud 1 End is respectively I 1-1 of screw rod, II 1-2 of screw rod;It is connected as between I 1-1 of screw rod, II 1-2 of screw rod by polished rod 1-3 transition One;The diameter of the polished rod 1-3 is less than the diameter of I 1-1 of screw rod, II 1-2 of screw rod;I 1-1 of screw rod described in short stud with The outside wall surface that the screw hole of rubber shock absorber groove side is threadedly coupled screw rod II described in short stud has to be connect with loop External screw thread;The center of screw rod II described in short stud has the hexagonal hole to cooperate with allen wrench;In conjunction with Fig. 3, With the tubular structure of step through-hole centered on the loop 2;The step through-hole is up big and down small structure;Platform The small diameter bore of stepwise through-hole and the screw rod of bolt are used cooperatively;The large diameter hole of step through-hole and the nut kiss of bolt 3 are matched; The top in step through-hole wall face has the internal screw thread connecting with screw rod II;The nut of the bolt is logical positioned at step In the large diameter hole in hole, the screw rod of bolt stretches out the screw thread of the step through-hole and the rubber shock absorber groove other side Through hole whorl connection.
There are two groups of symmetrically arranged through-holes in the outside wall surface of the loop 2.
In conjunction with Fig. 4, the bolt 3 has nut 3-1 and screw rod 3-2, and the top of the screw rod is polished rod, middle part is set It is equipped with the hexahedron 3-3 for bolt fastening, lower part is the threaded rod to be threadedly coupled with the tapped through hole.
When the utility model is used, allen wrench resists short 1 hexagonal hole of stud rotation and tightens short stud 1 Screw hole at the top of to rubber shock absorber;Bolt 3 passes through loop 2, and 3 hexahedron of rotating bolt makes bolt screw in rubber shock absorber lower end spiral shell Hole;2 upper end internal screw thread of loop is connect with short stud 1 with main 2 cylindrical surface through-hole of the loop rotation of lever card;It is rotated with spanner Bolt hexahedron adjusts precompressed amount;The device not only quickly and effectively solves the problems, such as rubber shock absorber useful space precompressed, and The stroke that rubber shock absorber is effectively controlled when diesel engine acutely shakes, improves reliability and the service life of rubber shock absorber.
