Abstract
The utility model relates to a shock absorbing bushing structure. An inner hole of the shock absorbing bushing is provided with a v-shaped slot; the shock absorbing bushing is matched with a V-shaped groove of a drill rod; and when being rotated, the drill rod drives the shock absorbing bushing to rotate together, so that relative movement between the drill rod and the shock absorbing bushing is eliminated, the support accuracy of the shock absorbing bushing on the drill rod is greatly improved, and the service life of the shock absorbing bushing is prolonged. The utility model adopts a technical scheme that the shock absorbing bushing structure comprises a shock absorbing bushing body, wherein the shock absorbing bushing body is provided with a central hole with the V-shaped groove; and the point angle of the V-shaped groove of the central hole is 120 degrees.
Description
One, technical field:
The utility model relates to a kind of shock-absorbing sleeve structure.
Two, background technology:
The drill gun length that deep hole drilling machine uses is longer, draw ratio is mostly above 50 times, add man-hour because of the unsettled oversize drilling rod shake that causes of drilling rod, influence crudy and bit life, therefore people are provided with the shock-absorbing sleeve that the center has endoporus for the drilling rod of drill gun to come supports drill rods more, to improve machining status, shock-absorbing sleeve 1 material is oil resistant rubber, endoporus 2 is circular (referring to Fig. 1 and Fig. 2), and drilling rod passes the shock-absorbing sleeve endoporus, drilling rod rotation and feeding, when rotating, drilling rod with the shock-absorbing sleeve endoporus relative friction is arranged, can cause the shock-absorbing sleeve endoporus to become rapidly big and lost efficacy, the life-span is shorter, and support accuracy is low.
Three, utility model content:
The utility model provides a kind of shock-absorbing sleeve structure in order to solve the weak point in the above-mentioned background technology, and is simple in structure, improved the support accuracy of shock-absorbing sleeve to drilling rod greatly, prolonged the service life of shock-absorbing sleeve.
For achieving the above object, the technical solution adopted in the utility model is: a kind of shock-absorbing sleeve structure, comprise the shock-absorbing sleeve body, and it is characterized in that: described shock-absorbing sleeve body is provided with the centre bore that has " V " type groove.
The drift angle of " V " type groove of described centre bore is 120 degree.
Compared with prior art, the advantage and the effect that the utlity model has are as follows: this practicality is new
Type shock-absorbing sleeve biggest advantage is that the shock-absorbing sleeve endoporus has v type groove, shock-absorbing sleeve matches with drilling rod " V " type groove, during the drilling rod rotation, drive shock-absorbing sleeve and do rotation together, eliminated relative motion between the two, and shock-absorbing sleeve also improves greatly to the support accuracy of drilling rod, has prolonged the service life of shock-absorbing sleeve.
Four, description of drawings:
Fig. 1 is the structural representation of existing shock-absorbing sleeve;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the utility model structural representation;
Description of symbols: 1-shock-absorbing sleeve body, 2-centre bore.
Five, the specific embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 3: a kind of shock-absorbing sleeve structure, comprise shock-absorbing sleeve body 1, described shock-absorbing sleeve body 1 is provided with the centre bore 2 that has " V " type groove, and the drift angle of " V " type groove of described centre bore 2 is 120 degree.
The utility model shock-absorbing sleeve is arranged on the drilling rod, matches with " V " groove on the drilling rod, during the drilling rod rotation, drives shock-absorbing sleeve and does rotation together, has eliminated relative motion between the two.
Claims (2)
1. a shock-absorbing sleeve structure comprises shock-absorbing sleeve body (1), it is characterized in that: described shock-absorbing sleeve body (1) is provided with the centre bore (2) that has " V " type groove.
2. a kind of shock-absorbing sleeve structure according to claim 1 is characterized in that: the drift angle of " V " type groove of described centre bore (2) is 120 degree.
