Description
Technical field
The utility model relates to a kind of laboratory rock sample and drills through the machine faucet device, be that a kind of laboratory rock sample that both can be applied to drills through chisel bit cooling on the machine and the device that clamps, also its clamping can be used for the drill bit cooling and the device that clamps of laboratory rock sampling on bench drill.
Background technology
The rig faucet device is that the water swivel that uses in the engineering is along with the difference of use occasion with non-rotary drilling fluid input pipe and the parts that the drilling rod of rotation is connected, and structure is very different, but ultimate principle all is the leakage that stops liquid coolant by motive seal.Laboratory rock sample on the market drills through that there is the relatively poor defective of versatility in employed water swivel more on the machine, and the laboratory rock sample of different model drills through the faucet device of machine can not be general, and the versatility of using on the bench drill similar with it is poorer.In addition, present laboratory rock sample drills through the machine water swivel and has aspect deficiencies such as function ratio is more single, sealing is relatively poor, drill through in order to overcome laboratory rock sample in the market that the versatility of machine water swivel is relatively poor, defective such as function singleness, sealing are bad, the utility model provides a kind of laboratory rock sample to drill through the machine faucet device.
Summary of the invention
It is convenient that the purpose of this utility model provides a kind of liquid coolant break-make control, sealing is good, highly versatile, laboratory rock sample that function is many drill through the machine faucet device, except having to the chisel bit refrigerating function, also has the good function of holding chisel bit tightly, both can be used as rock sample and drilled through chisel bit cooling and clamp device on the machine, also its clamping can have been used on bench drill.
The utility model in order to achieve the above object, the technical scheme of taking is: provide a kind of laboratory rock sample to drill through the machine faucet device, include grip nut, collet, mandrel, angular contact ball bearing, rotary oil seal, middle casing, ball valve, bear box, round nut, the round nut stop washer, hexagon socket cap head screw and end cap, described grip nut is fixed on the end of mandrel inside surface for the awl mouth by screw thread, collet is installed in the awl mouth of described mandrel, grip nut, the chisel bit clamp system that the awl mouth of collet and mandrel is formed; The axial end inside surface of described mandrel is the awl mouth, there is blind hole at the mandrel middle part, be drilled with radial direction through hole at nearly blind hole place, in the through hole middle casing is installed, adopt the rotary oil seal sealing between the both sides endoporus of middle casing and the mandrel, in the middle casing both sides bear box is installed respectively, two bearings housing end face is separately installed with end cap; End cap divides left and right end cap, and left and right end cap and bear box are fixed on the middle casing by hexagon socket cap head screw and elastic washer; Middle casing has into water duct in the through hole, water inlet is connected with ball valve on the duct; In the described bear box endoporus angular contact ball bearing is housed.
The described mandrel other end is the solid cylinder body structure, both can clamping on the chuck of bench drill, also can be connected with the main shaft that the laboratory rock sample drills through machine by shaft coupling, make device have good versatility.
Described end cap divides left end cap and right end cap, and left end cap, bear box, middle casing, bear box and right end cap connect as one by hexagon socket cap head screw and form complete housing.Because bear box cooperates with the outer ring of angular contact ball bearing, the inner ring of angular contact ball bearing cooperates with the outside surface of mandrel, so generally speaking, installs in use, and the rotation of mandrel can not drive the rotation of housing.Consider in use contingent various factors, do not rotate that described middle casing is drilled with two and is used to prevent that shell integral body from following the threaded hole that mandrel rotates on housing in order to ensure whole housing.Can be according on the line slideway auxiliary that the environment for use of reality utilizes these two threaded holes with screw housing to be fixed on bench drill or the machine that drills through is installed, prevent that the monolithic case transfer from rotating with mandrel.
Adopt the rotary oil seal sealing between the both sides endoporus of described middle casing and the mandrel, rotary oil seal adopts the high-quality product of the NOK KA3J of company series, makes device have excellent sealing performance, can bear the hydraulic pressure of 3.5MPa.
In the described bear box endoporus angular contact ball bearing is housed, wherein You Bian angular contact ball bearing one side inner ring is blocked by round nut stop washer and round nut and prevents that it from axially collecting together.Bear box inside is installed with single-row angular contact ball bearing, and housing can bear very big axial load.
The utility model laboratory rock sample drills through the machine faucet device, in the time of will being connected with chisel bit, employing turns the grip nut that is connected with mandrel thread, the inside surface of the outside surface of collet and the inside surface of mandrel and grip nut adopts cone match, holds chisel bit tightly thereby the endoporus of collet is dwindled; Also can change the specification of collet in good time, reach the effect of reliably holding chisel bit tightly according to the chisel bit of the different size that is connected.
Described mandrel is the power transmission member that drill bit creeps into rotation, also is that the main flow of drill bit liquid coolant is gone into passage, can form the liquid coolant inlet passage of sealing after the utility model laboratory rock sample drills through the machine faucet device and water pipe head is connected.Two-way valve is opened, and liquid coolant flows out from water pipe head, through water inlet duct, the through hole that is connected with ball valve on the middle casing, flows into mandrel and enters chisel bit endoporus cooling drill bit.Use two-way valve can control the break-make of cooling water channel easily.
Laboratory of the present utility model rock sample drills through the machine faucet device and has following advantage:
(1) this device has the rotary oil seal of high-quality in the design of the both sides of inlet opening, and the cooling duct sealing is good, can bear the hydraulic pressure of 3.5MPa.
(2) this device has been installed ball valve at place, water inlet duct, and direct control ball valve handle control water route break-make can make things convenient for the break-make of controlling cooling water channel in time.
(3) this apparatus structure compactness, weight are lighter.
(4) this device adopts collet to clamp chisel bit, can hold chisel bit reliably tightly, and the method for clamping and loading and unloading drill bit is simple, can also the collet that be fit to be installed reach the effect of reliably holding chisel bit tightly according to the chisel bit of multiple dimensions.This device both can be installed in the General Purpose Laboratory rock sample and drill through on the machine and use, but also clamping uses on common bench drill, and versatility is good, the multifunctionality of implement device.
