Description
Technical field
The utility model relates to a kind of normally closed type oild chuck, belongs to a kind of clamping device, and it is the device that is used for the clamping drilling tool that uses in the underground drill rig under the coal mine.
Background technology
In the coal mining industry, tunnel, colliery probing is used very extensive with rig, and oild chuck is as a kind of mechanism of rig clamping drilling tool, its work under bad environment, this mechanism to safe and reliable require efficiently particularly important.For safe and reliable, well behaved chuck is provided, people are constantly carrying out technological improvement.China utility model patent CN92220886.7 has just proposed a kind of non-swinging type high-velocity through hole power oil cylinder.An end that it is characterized in that being connected in the pull bar on the main shaft power chuck connects supporting base, between supporting base and the piston angular contact ball bearing is housed.Simultaneously, be connected the Supporting ring on the main shaft and be connected between the connection seat on the cylinder body angular contact ball bearing also is housed.Such cylinder body and piston be not all with the main shaft high speed rotary, and just supporting base, Supporting ring, pull bar turn round with main shaft.But this chuck can only be applicable to mechanical processing machine, needs hydraulic cylinder to work simultaneously when work, is not suitable for the operation under the mine.
China utility model patent CN 200620030156.5 discloses a kind of fully automatic hydraulic chuck.Two main bodys of its chuck connect into an integral body by bearing pin; The outer ring of slip insert cooperates with the inner ring slideway of main body and can slide up and down relatively; Power cylinder is embedded in the inside of main body, and the piston rod of power cylinder is connected with guide peg and is fixed on the supporting disk; Junction plate links together slip insert and supporting disk; Wear ring is contained in the below of main body, the cleaning lacquer disk(-sc) be installed in wear ring below.This chuck is not suitable on the underground drill rig yet and uses.
The utility model content
Technical problem to be solved in the utility model, provide a kind of be applicable to use on the underground drill rig, the normally closed type oild chuck.
It is to realize by following technical scheme that the utility model will solve above-mentioned technical problem:
The normally closed type oild chuck, comprise chuck body, be arranged on slips, hydraulic cylinder, the chuck shell that is connected with hydraulic cylinder in the chuck body and be arranged on the chuck shell and the conduit of chuck body inside, the shell of hydraulic cylinder is connected with the chuck shell, the chuck piston of hydraulic cylinder inside is connected by thrust ball bearing with its inner chuck body, is provided with one group of disk spring in the inner chamber of chuck shell and between the chuck body.
Further improvement in the technical proposal is: the chuck shell is provided with two air-vents, so that the gas in the space at disk spring place can be come in and gone out when chuck piston is up and down smoothly.
Slips and chuck body are equipped with by taper surface, conduit passes from chuck shell, disk spring and chuck body inside, the upper end is connected with chuck body, the lower end of conduit, is provided with angular contact bearing in the chuck shell, and conduit is connected by angular contact bearing with the chuck shell.Have the open slot of placing slips in the upper end of conduit, the quantity of open slot is corresponding with the quantity of slips, and slips is placed in this open slot.Two semi-rings are set above the slips, and semi-ring is stuck in the annular groove that is provided with on the outer wall of conduit, is the chuck lid above the semi-ring, and the chuck lid is connected with semi-ring by screw.
Further improvement in the technical proposal is: the inside of slips is provided with the turn that slips is strutted.
Because the progress of having adopted technique scheme, the utility model to obtain is:
The utility model is a kind of mechanism of tunnel, colliery probing with the clamping drilling tool of rig.Overall structure adopts dish spring chucking, hydraulic unlock.Have only and change or primer fluid cylinder pressure just when unloading drilling tool, therefore can prolong the application life of hydraulic unit, its clamping is reliable, operate lightly, and slips is movable flexible, and long service life can obviously be increased work efficiency.
The chuck piston of hydraulic cylinder and chuck body are connected by thrust ball bearing, chuck body is rotated flexibly, and hydraulic cylinder needn't rotate.Thrust ball bearing and supravasal angular contact ball bearing are used, realized that chuck is when stepping up powerful drilling tool, in the progradation of feed system, what not only can keep rotating part rotates freely but also guarantees centering accurately, the requirement for dynamic balance under being more suitable for running up.
The air-vent that the chuck shell is established can make the gas in the space at disk spring place can come in and go out smoothly when chuck piston is up and down, reduces the resistance of piston activity, makes chuck body, chuck piston realize moving back and forth flexibly under disk spring and oil pressure effect.
The open slot that the conduit end face is offered makes by several slips of forming to set within it, and with two semi-rings slips is limited in the open slot, and radially mobile unrestricted of slips; Only need when changing slips the end face screw is unclamped, both can easily take off semi-ring, take out slips thereupon, no longer need to dismantle other parts, avoided changing the loaded down with trivial details dismounting of slips in the past; Strut slips with turn simultaneously, replaced original employing dovetail groove that the rigid connection of slips is installed, reduced the wearing and tearing between slips and conduit, the chuck body, make the slips activity more flexible.
