Description
Technical field
The invention belongs to lathe boring technical field, and in particular to a kind of lathe tail seat with ratchet structure.
Background technology
The tail seat that lathe carries, when carrying out turning, top well can be reached and pretend to use, lathe is logical in drilling
Cross drilled goods to rotate, the motionless mode of drill bit is drilled, and normal operating continues rotating machine tailstock runner and carried 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 larger to the pressure of drill bit during hole, operating personnel are in the case of runner propelling pressure deficiency, it will usually take crowbar sharp
Rotating wheel is carried out by the use of lathe as fulcrum, this method not only damages lathe as currently the only method, and due to pressure
It is unstable, can usually damage tail seat, drill bit etc., larger potential safety hazard to operating personnel and equipment be present.
The content of the invention
The present invention in order to solve lathe boring when, tailstock runner need high pulling torque manually can not rotating wheel the problem of, carry
For a kind of lathe tail seat of ratchet structure.
The present invention adopts the following technical scheme that：
A kind of lathe tail seat with ratchet structure, including tail seat and runner retractor device, the tail seat and runner stretch
Ratchet device is connected between device, ratchet device includes adjustable rocking bar, ratchet casing and ratchet, and ratchet and tail seat are same
Axle, it is installed in ratchet box body, adjustable rocking bar is connected with coaxial ratchet, and adjustable rocking bar hypomere, which is provided with, stirs pawl wheel
Hook tooth is stirred, brake ratchet tooth is provided with ratchet box body, ratchet box is provided with the displacement for being used to exit brake ratchet tooth and drawn in vitro
Hand.
The runner retractor device is the screw rod with rocking bar, and ratchet and adjustable rocking bar are connected with screw rod.
The ratchet casing is provided 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 casing is provided with ratchet device displacement spring close to one end of tail seat in the axial direction, away from tail seat
One end be provided with spacing jump ring.Spacing jump ring is to prevent ratchet device from jumping out backwards.
The present invention is to enter to be about to the big distance of drill bit by runner retractor device to adjust to the starting point of drilled hole site, then
Carry out stirring drive screw progress at the uniform velocity using ratchet structure, stable power promotes drill bit.Due to ratchet structure
Particularity, the speed that normal speed push-and-pull spanner can promote drill bit is uniform, by being adjusted to designed adjustable spanner
It is whole, for the aperture in the range of section diameter, the pressure of propulsion drill bit can be made balanced, reach the protection person, the safety of equipment.This
Device is transformed on original tail seat, and small volume, cost are relatively low, has good social and economic benefits.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention；
The schematic diagram of Fig. 2 positions core component ratchet device of the present invention.
In Fig. 1：1- tails seat, 2- ratchet devices, 3- runners retractor device, 4- can adjust rocking bar, 5- ratchets casing, 6- spine
Wheel, 7- brake ratchets tooth, 8- stir hook tooth, 9- ratchet devices displacement spring, the spacing jump rings of 10-.
Embodiment
With reference to accompanying drawing, the embodiment of the present invention is described further：
Ratchet device 2 and runner retractor device 3. are installed on tail seat 1 as shown in Figure 1
As shown in Fig. 2 ratchet casing 5 is installed with all ratchet device parts, ratchet is stirred wherein being installed with adjustable rocking bar 4
Tooth 8 is fixed on using key connection on the screw rod of tail seat 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
Rotated using runner retractor device and drill bit is moved to drilled hole site, started lathe boring and start.Operate ratchet device can
Adjust rocking bar and carry out drill bit propulsion, rocking bar should adjusted to appropriate length, moved by adjustable rocking bar before according to graduation indication
Torque arm length can make drill bit promote pressure with bit bore to need pressure balanced 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
Complete.Lower limit jump ring can be removed when needing drill bit to exit, spring promotes ratchet device to translate out card key position, realizes that ratchet fills
Put and separated with screw rod, shake flexible runner and can be achieved to drill bit（It is top）Exit function.The present apparatus thoroughly solves commonly
During lathe boring the problem of bit feed insufficient pressure, by the present apparatus can at the uniform velocity and pressure stability completion boring work, and
And good protection staff, equipment safety can be played a part of.
