Impact shock acts through drilling rod and is delivered on dynamic head main spindle, on the impact of the parts such as unit head internal bearings, gear very
Greatly, so increasing a buffer unit between unit head and impacter, it is possible to effectively slow down the impacter impact to unit head
Effect of vibration, increases service efficiency and the life-span of unit head.
Utility model content
This utility model solves the deficiencies in the prior art and a kind of can effectively alleviate down-the-hole air hammer to unit head
Impact shock effect, protects screw thread, improves the hidden hole drilling unit head buffer unit in the service life of hidden hole drilling unit head.
A kind of hidden hole drilling unit head buffer unit, installs including splined shaft described in threaded connector, splined shaft and spline housing
In spline housing, described splined shaft is arranged on threaded connector by spline housing, described threaded connector and dynamic head main spindle
Connect, outside one end that described dynamic head main spindle is connected with threaded connector on be machined with a circle groove, described threaded connector
Upper surface be connected with dynamic head main spindle by flange, described flange is that at least two halves are assembled, and the upper end of described flange sets
Having and the flange collar of described groove match, after described flange is connected with threaded connector, described flange collar is arranged in described groove.
The spring washer connection that described flange, threaded connector and spline housing pass through bolt, are arranged on bolt.
Described flange, threaded connector and spline housing connect also by the elastic cylindrical pin between adjacent bolt.
Described threaded connector is threadedly coupled on dynamic head main spindle by API.
Also include the first cushion pad, the second cushion pad, sleeve, piston rod packing circle, an O RunddichtringO and the 2nd O type
Sealing ring, described splined shaft part in spline housing in the movement direction and is provided with the first buffering between threaded connector
Between pad and spline housing, the second cushion pad is installed, an O type is installed between described spline housing and threaded connector joint face
Sealing ring seals, and described threaded connector and dynamic head main spindle joint face are provided with the 2nd O RunddichtringO sealing, described screw thread
The middle part of union joint and splined shaft is provided with pore, and the pore of described threaded connector and splined shaft passes through sleeve connection, described set
Being provided with the sealing of piston rod packing circle on cylinder and threaded connector and splined shaft joint face, described splined shaft is with spline housing outlet even
Being provided with dust ring in junction, described spline housing is provided with grease nipple, fills in the space between described splined shaft and spline housing
Butter.
Owing to using said structure, by the effect of flange so that during unit head reversion, threaded connector and unit head master
Axle will not get loose, and in unit head work process, compressed gas is sealed with a described O type by described piston rod packing circle
Circle, the 2nd O RunddichtringO seal, and the impact shock that impacter produces acts through the first cushion pad and is eased, spline
The second cushion pad between axle and spline housing can alleviate collision effect during shadoof, and two cushion pads can alleviate when unloading bar
Damage to screw thread.
In sum, a kind of hidden hole drilling unit head buffer unit that this utility model provides, not only there is vibration damping, buffering,
The effect of protection screw thread, also has certain guide effect, and and dynamic head main spindle between possess locking functions.

Detailed description of the invention
The embodiment combined in accompanying drawing is further described by this utility model below:
Seeing Fig. 1 and Fig. 2, threaded connector 1 is threadedly coupled on dynamic head main spindle 16 by API, fills bottom spline housing 7
Entering the second cushion pad 11, be inserted in spline housing 7 by splined shaft 8, sleeve 12 is placed in splined shaft 8 and threaded connector 1, sleeve 12
On equipped with piston rod packing circle 14, equipped with dust ring 10 and grease nipple 6, spline housing 7 and threaded connector 1 end face on spline housing 7
Between equipped with an O RunddichtringO 3, equipped with the 2nd O RunddichtringO 15 between threaded connector and dynamic head main spindle 16, spline housing 7,
Threaded connector 1 and flange 2 are linked together by bolt 4, spring washer 5, elastic cylindrical pin 9, splined shaft 8 with threaded
It is lined with the first cushion pad 13 between 1.When unit head works, compressed gas carries out close by O with piston rod packing circle
Envelope, load torque is delivered to threaded connector by spline pair, bolt, elastic cylindrical pin, and then is transferred to unit head.
In this utility model, the first cushion pad 13 and the second cushion pad 11 can play buffering, vibration isolation, the work of protection screw thread
With；The spline pair that splined shaft 8 and spline housing 7 form can not only transmit torque and also act as certain guide effect；Flange 2 can
When preventing unit head from inverting, threaded connector 1 gets loose with dynamic head main spindle 16, plays locking effect.
