Abstract
The invention discloses a numerically controlled lathe hydraulic chuck hard claw trimmer. The numerically controlled lathe hydraulic chuck hard claw trimmer comprises a fixed ring (1). Three adjusting bolts (2) penetrating through the fixed ring (1) in the radial direction are evenly distributed on the fixed ring (1). The tops of the adjusting bolts (2) are each connected with a locking nut (3) through threads so as to fix the positions of the adjusting bolts (2). A locating pin (4) perpendicular to the adjusting bolts (2) is installed on the lower portion of one of the three adjusting bolts (2) in a sleeved mode. The center line of the locating pin (4) is parallel to the center line of the fixed ring (1). The locating pin (4) is inserted and fixed in a locking hole (7) of a chuck claw (6) of a numerically controlled lathe hydraulic chuck (5), so that the side face of the fixed ring (1) is tightly attached to the end face of the chuck claw (6). The numerically controlled lathe hydraulic chuck hard claw trimmer has the advantages of being high in rigidity and corrosion resistance and good in universality.
Description
Technical field
The present invention is a kind of hard pawl trimmer of numerically controlled lathe oild chuck, belongs to field of mechanical technique.
Background technology
After using abrasion, the hard pawl of chuck produces " horn mouth " type to the hard pawl of numerically controlled lathe oild chuck, clamps cambered surface and work
Part external diameter deviates, and causes piece-holder not live, and workpiece surface is crushed, and produces the phenomenons such as workpiece waste product.So during use
Needs often carry out reconditioning to the hard pawl of oild chuck.Race ring was clamped using emery wheel grinding-head come to the hard pawl of chuck using claw in the past
Reconditioning is carried out, because clamped race ring external diameter immobilizes, is produced with race ring sometimes during emery wheel grinding-head reconditioning
Interfere with each other, it is impossible to the arc sizes needed for meeting.
The content of the invention
The present invention is just being directed to above-mentioned of the prior art not enough and is designing hard there is provided a kind of numerically controlled lathe oild chuck
Pawl trimmer, the purpose is to the radial dimension required for can adjusting claw, between being eliminated when chuck is clamped by alignment pin
Gap, it is ensured that emery wheel grinding-head to after claw reconditioning with use during jaws clamp when, claw cambered surface and workpiece external diameter
Uniformity.
The purpose of the present invention is realized by following technical measures：
This kind of hard pawl trimmer of numerically controlled lathe oild chuck, it is characterised in that：Trimmer includes a retainer ring (1), should
Three adjustment bolts for passing radially through retainer ring (1) (2) are uniformly distributed in retainer ring (1), adjustment bolt passes through at the top of (2)
A locking nut (3) is threadedly coupled with the position of fixed adjustment bolt (2), the bottom of in three adjustment bolts (2)
One alignment pin (4) vertical with adjustment bolt (2) of suit, the center line of the alignment pin (4) is put down with the center line of retainer ring (1)
OK, the alignment pin (4) is inserted and is fixed in the locking hole of the chuck jaws of numerically controlled lathe oild chuck (5) (6) (7), is made solid
The side for determining ring (1) is close on the end face of chuck jaws (6).
The advantage of the hard pawl trimmer of numerically controlled lathe oild chuck of the present invention is that the trimmer uses process medium plain emery wheel
The features such as bistrique is without interference, required claw arc sizes easy to adjust, its stable performance, good versatility.
Brief description of the drawings
Fig. 1 is the mounting structure schematic diagram of trimmer of the present invention and numerically controlled lathe oild chuck (5)
Fig. 2 is the shape and structure schematic diagram of the retainer ring (1) of trimmer of the present invention
Specific embodiment
Technical solution of the present invention is further described below with reference to drawings and Examples：
Referring to shown in accompanying drawing 1~2, this kind of hard pawl trimmer of numerically controlled lathe oild chuck includes a retainer ring 1, and this is fixed
Three adjustment bolts 2 for passing radially through retainer ring 1 are uniformly distributed on ring 1, the top of adjustment bolt 2 is connected through a screw thread one
With the position of fixed adjustment bolt 2, the bottom of is set with one with adjustment bolt 2 to locking nut 3 in three adjustment bolts 2
Vertical alignment pin 4, the center line of the alignment pin 4 and the centerline parallel of retainer ring 1, the alignment pin 4 are inserted and are fixed on number
In the locking hole 7 of the chuck jaws 6 for controlling lathe hydraulic chuck 5, the side of retainer ring 1 is set to be close on the end face of chuck jaws 6.
Using Gr15 steel through lathe process, trisection M16 screwed holes, thermally treated hardness reaches the retainer ring 1 of trimmer
To 60HRC-62HRC, the rigidity of part is improve, wearability meets use requirement.
Alignment pin 4 is processed using Gr15 steel through the thick bed of car, is bored φ 16.1 and is worn bolt hole, and thermally treated hardness reaches
60HRC-62HRC, improves the rigidity of part, wearability, and peripheral milling processes the parts of external diameter φ 19, improves the positioning accurate of part
Degree, meets use requirement.
When using, numerically controlled lathe oild chuck 5 eliminates the gap of chuck first by the Workpiece clamping of required processing, then will
The alignment pin 4 of trimmer is installed in the locking hole 7 of the hard pawl of oild chuck, by adjusting the adjustment spiral shell in trimmer retainer ring 1
The top locking nut 3 of bolt 2 determines the arc sizes needed for chuck jaws 6, and numerically controlled lathe oild chuck 5 unclamps withdraws from workpiece
Afterwards, clamping and positioning pin 4 determines arc sizes again, finally carries out reconditioning to the hard pawl of chuck using emery wheel grinding-head 8, it is ensured that emery wheel grinds
Head to after claw reconditioning with use during jaws clamp when claw cambered surface and workpiece external diameter uniformity.Meet last
Use requirement.
Compared with existing apparatus, its advantage is after ensure that emery wheel grinding-head 8 to claw reconditioning to trimmer of the present invention
With during use during jaws clamp, the uniformity of claw cambered surface and workpiece external diameter.
