Abstract
The utility model discloses a punch capable of precisely positioning. The punch comprises an upper punch, an intermediate punch and a lower punch which are integrally interconnected; an annular step connected in match with the front end of an air hammer is formed in the part where the upper punch is combined with the intermediate punch; the intermediate punch is cylindrical; annular concave grooves which are distributed along the peripheral direction are formed at the lower part of the outer surface of the intermediate punch and are used for coiling steel wires; the lower punch is in the shape of a cone which is small in cross section of the lower end; and a through hole for passing the steel wires is formed between each annular concave groove and the lower end surface of the lower punch. The punch capable of precisely positioning is applied to installing of elastic round pins of speed changers, has functions in guiding and positioning, is high in installing efficiency, and hardly causes injury to hands.
Description
Technical field
The utility model relates to the machining equipment technical field, especially relates to a kind of drift of accurate positioning of the elastic cylindrical pin erecting tools that is applicable to speed changer.
Background technology
At present, the installation method of the elastic cylindrical pin of speed changer is: at first, lead with hand, then, with hammer elastic cylindrical pin is in place.
There is the defective that guiding is inaccurate, the set-up time long, hand is injured by hammer easily in this installation method.
Chinese patent Granted publication number: CN202239213U, May 30 2012 Granted publication day, disclose a kind of drift, comprised that drift effect end, an end connect the drift connector of drift effect end, the bore of described drift connector is greater than the bore of drift effect end.This utility model is for the drift on the punching press grinding tool.
The utility model content
The utility model is of the prior art elastic cylindrical pin can only be installed by hand in order to overcome, the deficiency that existing guiding is inaccurate, the set-up time is long, hand is injured by hammer easily provides a kind of drift of accurate positioning of the elastic cylindrical pin erecting tools that is applicable to speed changer.
To achieve these goals, the utility model is by the following technical solutions:
A kind of drift of accurate positioning, described drift comprise top drift, middle part drift and the bottom drift that is connected as a single entity; Binding site upper, the middle part drift is provided with for the ring-shaped step that is connected with the pneumatic hammer front end, and the middle part drift is cylindrical, and drift outer surface bottom, middle part is provided with the annular groove that along the circumferential direction distributes for winding steel wire; The bottom drift is the little taper shape of lower end cross-sectional area, is provided be used to the intercommunicating pore that passes steel wire between the lower surface of annular groove and bottom drift.
Drift of the present utility model and pneumatic hammer, volute spring and steel wire are connected, and volute spring is positioned at the outside of pneumatic hammer and drift binding site; One end of steel wire is wrapped in the annular groove, and the steel wire other end passes the lower surface that intercommunicating pore arrives the bottom drift, and the certain-length that extends out from the lower surface.
When the erecting tools that adopts drift of the present utility model and pneumatic hammer, volute spring and steel wire to consist of carried out the elastic cylindrical pin installation of speed changer, steel wire had played guide effect, and location and installation are finished continuously, and installation effectiveness is high.
Top drift, ring-shaped step are fixed with pneumatic hammer and are connected.
Elastic cylindrical pin is enclosed within on the steel wire, steel wire is inserted installing hole, press the pneumatic hammer switch, under the effect of volute spring, pneumatic hammer is done the reciprocating impact motion, and pneumatic hammer promotes the bottom drift and travels forward, by the accurate guiding of steel wire, the bottom drift promotes elastic cylindrical pin and enters in the installing hole.
When elastic cylindrical pin entered installing hole fully, the bottom punch end face played position-limiting action, decontroled the switch of pneumatic hammer after elastic cylindrical pin is in place.
As preferably, described top drift is and coaxial cylindrical of middle part drift that the diameter of top drift is less than the diameter of middle part drift.
As preferably, the cross section of described annular groove is semicircle.
As preferably, the upper port of described intercommunicating pore is positioned on the lower wall of annular groove, and the lower port of intercommunicating pore is positioned at the middle part of the lower surface of bottom drift.
As preferably, ring-shaped step and binding site upper, the middle part drift are respectively equipped with smooth transition surface.
As preferably, the edge of described top drift upper end is provided with chamfering.
As preferably, the diameter of intercommunicating pore is 2.5 millimeters to 3.5 millimeters.
As preferably, the length of drift is 120 millimeters to 130 millimeters.
Therefore, the utlity model has following beneficial effect: (1) is applicable to the installation of the elastic cylindrical pin of speed changer; (2) have guide-localization function, installation effectiveness height; (3) be difficult for causing the hand damage.
