Description
Technical field
The utility model relates to a kind of gear assembling fixture.
Background technology
Balancer casing assembly in the prior art, gear and trunnion shaft angle are very crucial in the technology in the balancer casing, angular error directly influences the dynamic balancing of the running of engine, influence vibrations of engine complete machine and noise, balance shaft assembly is fitted together by two of gears, and guarantee between trunnion shaft eccentric block center and the gear teeth angle 90 ° 0 ' ± 40 ', original employing setting-out assembling, result's angular error when assembling is big especially, one cover assembly gear is wanted repeated disassembled and assembled, trunnion shaft is after dismounting, and the precision of axle reduces so that scrap, and has not only wasted trunnion shaft but also influenced manufacturing schedule, labor strength is big, and production efficiency is very low.
The utility model content
The purpose of this utility model provides a kind of manufacturing schedule of promoting, and reduces labor strength, and the gear assembling fixture of production efficiency is provided.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of gear assembling fixture, comprise trunnion shaft, gear, locator, go up top, down top, guide pillar, go up locating shaft, go up alignment pin, go up location-plate and following location-plate, described gear is installed in the trunnion shaft bottom, following top being installed on the gear, gear is installed in down on the location-plate with top down jointly, last location-plate links to each other by guide pillar with following location-plate, last locating shaft is installed on the location-plate, go up top being installed on the locating shaft, locator is connected between guide pillar and the gear.
On the described guide pillar spring is installed.
Describedly floating spring is installed on down top.
The utility model gear assembling fixture is promoted manufacturing schedule the service life that can improve trunnion shaft, reduces working strength of workers, enhances productivity.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a kind of gear assembling fixture of the utility model front view;
Fig. 2 is that the B-B of Fig. 1 is to cutaway view.
Among the figure: 1, trunnion shaft; 2, gear; 3, locator; 4, top down; 5, guide pillar; 6, go up locating shaft; 7, go up alignment pin; 8, go up location-plate; 9, following location-plate; 10, floating spring; 11, spring; 12, upward top.
The specific embodiment
As Fig. 1, shown in Figure 2, the utility model gear assembling fixture, comprise trunnion shaft 1, gear 2, locator 3, following top 4, guide pillar 5, last locating shaft 6, last alignment pin 7, last location-plate 8, following location-plate 9, floating spring 10, spring 11, go up top 12, gear 2 is installed in trunnion shaft 1 bottom, top 4 be installed on the gear 2 down, gear 2 and top 4 be installed in down on the location-plate 9 jointly down, last location-plate 8 links to each other by guide pillar 5 with following location-plate 9, last locating shaft 6 is installed on the location-plate 9, last alignment pin 7 and last top 12 is installed on the locating shaft 6, locator 3 is connected between guide pillar 5 and the gear 2, spring 11 is installed on the guide pillar 5, floating spring 10 is installed in down on top 4, the utility model gear assembling fixture design principle is: by to trunnion shaft 1 and 2 two component technology analyses of gear, according to the designing requirement of drawing, gear 2 is placed on down on the location-plate 9, with the external diameter and the tooth centralized positioning of gear 2, realize the location fully of gear; Two ends centre bore with trunnion shaft 1 is a benchmark, trunnion shaft 1 is fixed on top 12 and following top 4, carry out rotational positioning by 7 pairs of trunnion shafves of last alignment pin 1, thereby make trunnion shaft 1 and gear 2 form certain angular relationship, by anchor clamps both sides guide pillar 5 location-plate 8 and following location-plate 9 accurately locates again, thus make trunnion shaft 1 and gear 2 assemble angles be 90 ° 0 ' ± 40 '.
The concrete course of work of the utility model gear assembling fixture is: a, assembling fixture cleaned keep flat and be fixed on the press bench;
B, go up location-plate 8 and guide pillar 5 cooperation places filling lubricating oil, it is lubricated good with guide pillar 5 to go up location-plate 8 when guaranteeing to press-fit, free sliding;
C, gear 2 (1022034-57K) is located with the tooth external diameter, lie in down on location-plate 9 locating holes, carry out the tooth location with 3 pairs of gears of locator 2, make angled 72 ° 49 of tooth center and anchor clamps X-axis ', the six-freedom degree of limiting gear, that is: X-axis moves, X-axis is rotated, y-axis shift is moving, Y-axis is rotated, the Z axle moves, the Z axle rotates;
D, trunnion shaft 1 (1022026-57K) is located with the two ends centre bore, stand up on last top 4, down top 12, using 7 pairs of trunnion shafves 1 of alignment pin positions, make angled 0 ° of balance weight center and anchor clamps X-axis, the six-freedom degree of limiting balance axle, that is: X-axis moves, X-axis is rotated, y-axis shift is moving, Y-axis is rotated, the Z axle moves, the Z axle rotates;
E, trunnion shaft 1, gear 2 is at last location-plate 8, after locating on the following location-plate 9, opening the forcing press switch assembles, press ram is pushed down locating shaft 6, location-plate 8 is axially moved down along Z, when the trunnion shaft 1 outer diameter of axle contacts with gear 2 endoporus, along with the continuation of pressure head is moved, trunnion shaft 1 and gear 2 fit together by illustrated angle, top 4 in floating spring 10 effect lower compression down, avoid assembling to interfere, when last trunnion shaft 1 assembling puts in place, unclamped press ram, last location-plate 8 makes location-plate 8 self-returns at both sides guide pillar 5 under spring 11 effects, carry out next workpiece again and install.
