Abstract
The invention relates to a slip component for a rubber sleeve type hydraulic chuck. The slip component comprises slips 1, adjusting baffles 2 and four springs 3. The front and back sides of each slip 1 are provided with four square grooves respectively, and the upper and lower sides of each slip are provided with two columnar holes respectively; the front and back sides of each adjusting baffle 2 are provided with two square bosses respectively; the four springs are respectively mounted in the four columnar holes of the two adjacent slips 1, so that the four slips 1 can be cylindrically mounted in the rubber sleeve. When the chuck works, the adjusting baffles guide radial movement of the slips, abrasion of the rubber sleeve and the slips can be remarkably reduced, assistance time is shortened, operation cost is reduced, and system efficiency is improved.
Description
Technical field
The present invention relates to a kind of gripping mechanism, belong to boring mechanic field, be specifically related to the slip assemblies on rubber oild chuck for a kind of full-hydraulic power head drill.
Background technology
Chuck is one of full-hydraulic power head drill independently vitals, its function is to clamp drilling rod, and to drilling rod transmitting torque and axial force, drive drilling tool realize revolution and feed, and auxiliary movement during processing accident, also can match with clamper and there is function stubborn, that unload drilling rod and lifting (or removing) drilling tool.The condition of work of chuck is severe, must bear the axial load of rig maximum and maximum flywheel moment, and act frequently.The performance of chuck directly has influence on efficiency and the quality of creeping into.
At present, the form of structure of oild chuck adopts most often rubber.The main manifestations that rubber oild chuck lost efficacy is the wearing and tearing of packing element and slips, changes packing element and is different from slips and miscellaneous part, need to be by chuck integral demounting, and each parts are ressembled, and non-cutting time is long, and operating cost is high, has a strong impact on system effectiveness.
Summary of the invention
For above-mentioned deficiency, the object of the present invention is to provide a kind of rubber oild chuck slip assemblies simple in structure, easy to process, that very easily assemble.
For realizing object of the present invention, the technical scheme that the application takes is as follows:
Rubber oild chuck slip assemblies of the present invention, is comprised of slips, regulating fender and spring.Before and after described slips, both sides are provided with four square grooves, and upper and lower both sides are provided with two groups of cylinder holes; Before and after described regulating fender, both sides are provided with two square boss.
Described spring has four groups, is arranged on respectively in two groups of cylinder holes of adjacent two slips, makes four slips become cylindric integral installation in packing element.
The square boss of described regulating fender is arranged in the square groove of slips.
Between described slips and regulating fender, be provided with the fit clearance 2b that guarantees that slips moves flexibly, and the slips amount of opening a.
The diameter dimension Φ of described slips is a kind of in the plurality of specifications drilling rod of slips clamping.
Beneficial effect:
The present invention can significantly improve full-hydraulic power head drill with the packing element on rubber oild chuck and the life-span of slips, reduces fault time, reduces operating cost, improves drilling efficiency;
Slips of the present invention and regulating fender coordinate to be installed, and its advantage is mutually to have limited circumferentially collecting together and endwisely slipping of the other side;
Regulating fender of the present invention moves radially and play the guiding role slips when chucking work;
Slips of the present invention, under the effect of spring, can automatically reset along the guiding of regulating fender, effectively reduces the wearing and tearing of slips to drilling tool;
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is left pseudosection of the present invention.
Wherein, the 1st, slips; The 2nd, regulating fender; The 3rd, spring.Size a is the slips amount of opening; B is the gap of slips and regulating fender; Φ is drill pipe diameter.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Referring to Fig. 1,2, rubber oild chuck slip assemblies of the present invention, comprises slips 1, regulating fender 2 and spring 3.Described slips 1 both sides, front and back are provided with four square grooves, and upper and lower both sides are provided with two groups of cylinder holes; Described regulating fender 2 both sides, front and back are provided with two square boss; Described spring 3 has four groups, is arranged on respectively in two groups of cylinder holes of adjacent two slips 1, makes 1 one-tenth cylindric integral installation of four slips in packing element; The square boss of described regulating fender 2 is arranged in the square groove of slips 1; Between described slips 1 and regulating fender 2, be provided with the fit clearance 2b that guarantees that slips moves flexibly, and be not less than a.
Finally it should be noted that: obviously, above-described embodiment is only for the application's example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments, and the apparent variation of being amplified out thus or change are still among the protection domain in the application's type.
