The utility model discloses a kind of lock nuts and the collet chuck being used cooperatively with lock nut, stepped hole is coaxially offered in the lock nut, internal screw thread is provided on the macropore oral pore wall of the stepped hole, the axle center that stepped hole is surrounded on the step surface of the stepped hole is arranged with multiple grooves in rotational symmetry.The collet chuck is coaxially arranged with through-hole, offers a plurality of slit on the hole wall of described through-hole one end side by side along collet chuck length direction and forms claw, corresponds on the claw end face and be provided at the position of each groove for the protrusion mating with groove.The lock nut and collet chuck of the utility model can be used in conjunction with each other to solve existing knife handle when carrying out high-speed rotation, and lock nut is easy to loosen, the technical issues of causing chucking power to be lower or lose chucking power.
Description
Technical field
The affiliated machine tooling tooling technical field of the utility model more particularly to a kind of lock nut and match with lock nut
Close the collet chuck used.
Background technique
Knife handle is the critical component for connecting cutter and lathe, and the stability and precision of knife handle decide the production of tool sharpening
The quality of product.Existing knife handle generally comprises clamp holder, collet chuck, lock nut, and described clamp holder one end is taper shank, the other end is handle
Head is coaxially provided with tapered hole in button, and the button outer circle is provided with external screw thread, and lock nut is provided with matches with the external screw thread screw thread
The internal screw thread of conjunction, the collet chuck for be arranged in tapered hole, the collet chuck by lock nut and button screw thread
Cooperation is to fix.When carrying out high-speed rotation, lock nut is easy to loosen existing knife handle, and chucking power is caused to be lower or lose clamping
Power, current solution are the threaded connection length lengthened between lock nut and button, do so the cost for leading to product
Increase.
Utility model content
In view of this, one of the purpose of this utility model is to provide a kind of lock nut, can be solved by the lock nut
When carrying out high-speed rotation, lock nut is easy to loosen existing knife handle, and the technology for causing chucking power to be lower or lose chucking power is asked
Topic.
The utility model solves above-mentioned technical problem by following technological means:
A kind of lock nut of the utility model coaxially offers stepped hole in the lock nut, the stepped hole
It is provided with internal screw thread on macropore oral pore wall, is arranged in rotational symmetry on the step surface of the stepped hole around the axle center of stepped hole more
A groove.
The purpose of this utility model two is to provide a kind of collet chuck being used cooperatively with lock nut, the collet chuck with
Lock nut is used cooperatively to solve existing knife handle when carrying out high-speed rotation, and lock nut is easy to loosen, and chucking power is caused to become
It is low or the technical issues of lose chucking power.
The utility model solves above-mentioned technical problem by following technological means:
A kind of collet chuck being used cooperatively with lock nut, the collet chuck are coaxially arranged with through-hole, the through-hole
It offers a plurality of slit on the hole wall of one end side by side along collet chuck length direction and forms claw, the slit is from through-hole one end
Orifice edge starting, which extends close to through-hole other end orifice edge, to be terminated, and the diameter of the claw is from collet chuck end to bullet
By gradually becoming smaller greatly in the middle part of spring collet chuck；It is provided on outer circumference surface on the collet chuck relative to the other end of claw one end outer
Screw thread；It corresponds on the claw end face and is provided at the position of each groove for the protrusion mating with groove.
The utility model has the beneficial effects that
The lock nut and collet chuck of the utility model can be used in conjunction with each other to solve existing knife handle and carry out height
When speed rotation, lock nut is easy to loosen, the technical issues of causing chucking power to be lower or lose chucking power.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model lock nut；
Fig. 2 is the structural schematic diagram of the utility model collet chuck；
Fig. 3 is a kind of structural schematic diagram of knife handle.
Specific embodiment
The utility model is described in detail below with reference to attached drawing:
A kind of lock nut of embodiment 1
As shown in Figure 1, one of the present embodiment lock nut, stepped hole 2 is coaxially offered in the lock nut 1,
It is provided with internal screw thread 9 on the macropore oral pore wall of the stepped hole 2, is rotated on the step surface of the stepped hole around the axle center of stepped hole
It has been symmetrically arranged multiple grooves 3.
A kind of collet chuck being used cooperatively with lock nut of embodiment 2
As shown in Fig. 2, a kind of collet chuck being used cooperatively with lock nut, the collet chuck 4 is coaxially arranged with logical
Hole 5 offers a plurality of slit on the hole wall of described 5 one end of through-hole side by side along collet chuck length direction and forms claw 6, described
Slit extends close to through-hole other end orifice edge and terminates from the starting of 5 one end orifice edge of through-hole, the diameter of the claw 6 from
By gradually becoming smaller greatly in the middle part of collet chuck end to collet chuck；The other end on the collet chuck relative to claw one end
External screw thread 7 is provided on outer circumference surface；Corresponded on the claw end face be provided at the position of each groove 3 for groove grafting
The protrusion 8 of cooperation.
As shown in Fig. 3 a kind of knife handle using Examples 1 and 2 comprising clamp holder, collet chuck, lock nut, institute
It states that clamp holder one end is taper shank, the other end is collet, blind hole is coaxially provided on collet, the collet outer circle is provided with external screw thread, is pressing from both sides
While head is threadedly engaged with lock nut, by the cooperation of protrusion and groove, lock nut will drive collet chuck rotation, into
And make collet chuck and blind threaded cooperation, and the benefit of above-mentioned setting is, when knife handle clamps cutter rotary work, collet chuck
The technical issues of becoming original tighter, can thoroughly solving processing accident caused by loosening because of lock nut.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
