Abstract
The utility model relates to an improved spiral tool joint suitable for connection of the spiral tool joint with various purposes. The upper and the lower bodies of the joint are divided into three driving jaws, by which the turning force is transmitted. The upper body is provided with a spring pin, and the lower body corresponds to an arc chute by which the axial force is transmitted. The upper and the lower bodies have the derived action through an axle hole.
Description
The utility model relates to a kind of improved spiral drill joint, is applicable to that the spiral drill of various uses connects.
Existing spiral drill is connected with following several form: 1. the tongue flange connects, and it adopts tongue to transmit turning power, adopts bolt to transmit axial force; 2. six square shaft holes connect with steady pin, and it adopts six square shafts, hole to transmit turning power, adopts steady pin to transmit axial force; 3. three drive key and hold-down screw connection, and its adopts three to drive keys transmission turning powers, adopts hold-down screw transmission axial force; 4. dog and spring steel wire connect, and it adopts dog to transmit axial force, adopt two locking spring steel wires to transmit axial force.More than the subject matter of connection form of various spiral drills be the dismounting inconvenience, bring difficulty to the operator, time-consuming bothersome, influence operating efficiency.
The purpose of this utility model is that a kind of improved spiral drill joint will be provided, and it can easy accessibility, and reliable in action has sufficient intensity.
The utility model is finished as follows: lower body is made three driving claws respectively on the spiral drill joint, transmits turning power by it, adopts the latch lock of being made up of locking handle, steel wire, fixture block lining and spring, as axial connection, transmits axial force; The upper body is provided with a spring catch in position, is provided with a fixedly deep-slotted chip breaker on the corresponding position of lower body; Last lower body plays the effect of correcting by the axis hole of suitable cooperation.
The utility model spiral drill ready-packaged joint is compared with existing tool joint, and 1. dismounting is very convenient, but automatic locking during dress uses easy special screwdriver one sled to open when tearing open; 2. reliable effect, the shearing resistance and the crush resistance strength of driving claw and lock pin are big; 3. it is proper to go up the lower body fit clearance, although the silt particle influence is arranged, also can not cause and insert and the difficulty of throwing off, and good correcting ability is arranged; 4. flat structure in the connection of cored screw drilling tool is adopted helps passing through smoothly of explosive-source explosive post.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing is the auger stem structure chart.
With reference to accompanying drawing.Joint upper body 1 and joint lower body 9 are welded on the two ends of core pipe 7 respectively, just form auger stem after welding hurricane band 8 again.Be provided with latch lock on joint upper body 1, latch lock is installed on 1 holder of joint upper body.Latch lock is made up of locking handle 2, steel wire 3, fixture block 4, lining 5, spring 6.The appropriate location of joint upper body 1 is provided with a spring catch, establishes a fixing deep-slotted chip breaker on joint lower body 9 positions corresponding with it.The square opening on 1 wall of joint upper body passes in latch lock fixture block 4 tooth portions, and shaft part cover upper spring 6 links with lining 5 and joint upper body 1 holder; Fixture block 4 axially outer ends connect locking handles 2 with screw thread and steel wire 3, and under the effect of elastic force, fixture block 4 tooth portions stretch into fixedly in the deep-slotted chip breaker, and two drilling tools are locked; Prize locking handle 2 with special bottle opener, compression spring 6 is pulled out fixture block 4 tooth portions in deep-slotted chip breaker, can make two drilling tools disengagements up and down.Joint upper body 1 and joint lower body 9 are made driving claw respectively, preferably adopt to be shaped as three driving claws of 5 °.The correcting that drilling tool connects is finished by the hole of joint upper body 1 and the axle head of joint lower body 9.The hole is preferably 0.20～0.35mm with the gap of axle.
