Description
Technical field
The utility model relates to saw blade sawtooth grinding equipment technical fields, and in particular to a kind of gear grinding machines feed mechanism
Differential attachment is finely tuned with longitudinal.
Background technique
Full-automatic relief grind machine is mainly used for the processing of saw blade relief grind, passes through feeding yaw fine tuning during the grinding process
Mechanism adjusts angle and the position of abrasive grinding wheel, and the feed mechanism on existing grinder, not only mechanism is complicated, clumsy, cost
Height, and reliability to equipment and precision all have an impact, and the position of abrasive grinding wheel is not high with angle precision after adjusting, causes to saw
Piece machining accuracy is not high, is unable to satisfy the requirement of high-end customer；And existing feed mechanism is carrying out abrasive grinding wheel longitudinal direction position
When setting mobile, steel ball service life of roller thereon is short, needs often to repair replacement, influences the production and processing of saw blade relief angle.
Utility model content
For disadvantage mentioned above, the utility model aim is to provide a kind of gear grinding machines feed mechanism longitudinal direction fine tuning differential machine
Structure, rotary fine adjustment handwheel make the bearing on differential adjusting rod carry out the fine tuning of lengthwise position, are not necessarily to steel ball idler wheel, further mention
The service life of Gao Liao mechanism.
The technical solution of the utility model technology is achieved in the following ways: a kind of gear grinding machines feed mechanism is longitudinal
Finely tune differential attachment, it is characterised in that: described longitudinal fine tuning differential attachment is by mounting base, differential nut, differential adjusting rod, micro-
Handwheel, fixed pin and bearing is adjusted to form；The mounting base is equipped with mounting hole, and differential nut one end is fixed on by fastener
At mounting hole, differential nut's other end is equipped with external screw thread；The differential adjusting rod is by bearing construction section, optical axis section, outer spiral shell
Line section composition, is connected between bearing construction section and external thread section by optical axis section；The optical axis section of the differential adjusting rod is located at
In the inner hole of differential nut, bearing construction section is located at the both ends of differential nut with external thread section；The bearing construction section
Place is equipped with groove, and bearing is installed in a groove by fixed pin；Two sections of internal screw threads are equipped in the trimming hand wheel, one section is interior
Screw thread A, another section is internal screw thread B, and trimming hand wheel is cooperated by the external screw thread on internal screw thread A and differential nut, and passes through interior spiral shell
The external screw thread that external thread section on line B and differential adjusting rod is equipped with cooperates.
The internal screw thread A and the internal screw thread B pitch of thread be not identical, trimming hand wheel every revolution, and differential adjusting rod is practical to be moved
Dynamic distance is the difference of two sections of lead of screw thread.
It is also equipped with dust cover on the trimming hand wheel, prevents dust to be adsorbed on differential adjusting rod by dust cover
External thread section influences the precision of outer external thread section and clean and tidy.
The utility model, structure is simple, and part is reduced, cost reduces, is easy to operate, steel ball idler wheel is not necessarily to, into one
Step improves the service life of mechanism.
Detailed description of the invention
Fig. 1 is the facing structure figure of the utility model.
Fig. 2 is the B-B cut away view of Fig. 1.
Fig. 3 is the three-dimensional structure diagram of the utility model.
In figure: 1 mounting base, 2 differential nuts, 3 differential adjusting rods, 4 trimming hand wheels, 5 fixed pins, 6 bearings, 7 dust covers.
Specific embodiment
Known by Fig. 1, Fig. 2, Fig. 3, a kind of longitudinal fine tuning differential attachment of gear grinding machines feed mechanism, longitudinal fine tuning is poor
Motivation structure is made of mounting base 1, differential nut 2, differential adjusting rod 3, trimming hand wheel 4, fixed pin 5 and bearing 6；The installation
Seat 1 is equipped with mounting hole, and 2 one end of differential nut is fixed at mounting hole by fastener, and 2 other end of differential nut is equipped with outer
Screw thread；The differential adjusting rod 3 is made of bearing construction section 31, optical axis section 32, external thread section 33, bearing construction section 31 and outer
It is connected between thread segment 33 by optical axis section 32；The optical axis section 32 of the differential adjusting rod 3 is located at the inner hole of differential nut 2
In, bearing construction section 31 is located at the both ends of differential nut 2 with external thread section 33；The bearing construction section 31 is equipped with recessed
Slot, bearing 6 are installed in a groove by fixed pin 5；Two sections of internal screw threads are equipped in the trimming hand wheel 4, one section is internal screw thread
A41, another section is internal screw thread B42, and trimming hand wheel 4 is cooperated by the external screw thread on internal screw thread A41 and differential nut 2, and is passed through
The external screw thread that external thread section 33 on internal screw thread B42 and differential adjusting rod 3 is equipped with cooperates.The internal screw thread A41 and interior spiral shell
The line B42 pitch of thread is not identical, 4 every revolution of trimming hand wheel, the practical moving distance of differential adjusting rod 3 be two sections of lead of screw thread it
Difference.It is also equipped with dust cover 7 on the trimming hand wheel 4, prevents dust to be adsorbed on differential adjusting rod 3 by dust cover 7
