Description
Technical field
The utility model belongs to lathe boring technical field, and in particular to a kind of lathe tail seat with ratchet structure.
Background technology
The included tail seat of lathe can reach top well and pretend to use, lathe is logical in drilling when carrying out turning
Drilled cargo rotation is crossed, the motionless mode of drill bit drills, and normal operating continues rotating machine tailstock runner and carries out to drill bit
Pressure, and pressure should be according to bore size relative equilibrium, and drill bit fltting speed should be at the uniform velocity.But in practical operation, due to boring
Need the pressure to drill bit larger when hole, operating personnel are insufficient in runner propelling pressure, it will usually take crowbar sharp
Lathe is used to carry out rotating wheel as fulcrum, this method not only damages lathe, and due to pressure as currently the only method
It is unstable, can usually damage tail seat, drill bit etc., there are larger security risks to operating personnel and equipment.
Invention content
When the utility model is in order to solve lathe boring, tailstock runner need large torque manually can not rotating wheel ask
Topic, provides a kind of lathe tail seat with ratchet structure.
The utility model adopts the following technical solution：
A kind of lathe tail seat with ratchet structure, including tail seat ontology and runner telescopic device, the tail seat sheet
Ratchet device is connected between body and runner telescopic device, ratchet device includes adjustable rocking bar, ratchet babinet and ratchet, ratchet
With tail seat ontology it is coaxial, be installed in ratchet box body, adjustable rocking bar is connect with coaxial ratchet, and rocking bar hypomere is adjusted and is equipped with
The hook tooth of stirring of ratchet wheel is stirred, brake ratchet tooth is equipped in ratchet box body, ratchet box is equipped in vitro for exiting braking
The displacement of hook tooth is shaken hands.
The runner telescopic device is the screw rod with rocking bar, and ratchet and adjustable rocking bar are connect with screw rod.
The ratchet babinet is equipped with angle dial, and ratchet jacking amount is accurately controlled using dial.
The adjustable rocking bar is stretching structure, to adjust the working length of rocking bar.
The ratchet babinet is equipped with ratchet device displacement spring close to one end of tail seat ontology in the axial direction, deviates from machine
One end of tailstock ontology is equipped with limit clamp spring.It is that ratchet device jumps out backwards in order to prevent to limit clamp spring.
The utility model is adjusted into the big distance of drill bit is about to the starting point of drilled hole site by runner telescopic device,
Then it carries out stirring drive screw progress at the uniform velocity using ratchet structure, stablizes being pushed to drill bit for power.Due to ratchet knot
The particularity of structure, normal speed push-and-pull spanner can make drill bit promote speed it is uniform, by designed adjustable spanner into
Row adjustment can make the pressure of propulsion drill bit balanced for the aperture within the scope of section diameter, reach and protect personal, equipment peace
Entirely.The present apparatus is transformed on original tail seat, and small volume, cost are relatively low, has good social and economic benefits.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model；
The schematic diagram of the positions Fig. 2 the utility model core component ratchet device.
In Fig. 1：1- tail seats ontology, 2- ratchet devices, 3- runners telescopic device, 4- be adjusted rocking bar, 5- ratchets babinet,
6- ratchets, 7- brake ratchets tooth, 8- stir hook tooth, 9- ratchet devices displacement spring, 10- limit clamp springs.
Specific implementation mode
In conjunction with attached drawing, specific embodiment of the present utility model is described further：
Ratchet device 2 and runner telescopic device 3. are installed on tail seat ontology 1 as shown in Figure 1
As shown in Fig. 2, ratchet babinet 5 is installed with all ratchet device components, stirred wherein being installed on adjustable rocking bar 4
Hook tooth 8 is fixed on using key connection on the screw rod of tail seat ontology 1.
As shown in Figure 1, 2, when the drill bit that tail seat clamps needs drilling, tail seat is moved integrally to operating position
Drill bit is moved to drilled hole site using the rotation of runner telescopic device, starts lathe boring and starts.Operate ratchet device can
It adjusts rocking bar and carries out drill bit propulsion, rocking bar should be adjusted to appropriate length according to graduation indication before use, moved by adjustable rocking bar
Torque arm length can make drill bit that pressure be pushed to need pressure balanced with bit bore according to the length of scale, play protect drill bit,
Tailstock and the effect for saving operating personnel's force.Continuing at the uniform velocity to stir rocking bar can make drill bit at the uniform velocity advance, until drill tasks
It completes.It can go lower limit clamp spring, spring that ratchet device is pushed to translate out card key position when needing drill bit to exit, realize ratchet dress
It sets and is detached with screw rod, shake the runner that stretches and can be realized to drill bit（It is top）Exit function.The present apparatus thoroughly solves commonly
When lathe boring the problem of bit feed insufficient pressure, by the present apparatus can at the uniform velocity and the completion boring work of pressure stability, and
And good protection staff, equipment safety can be played the role of.
