Abstract
The utility model puts forward an output shaft synchronous pitch-changing mechanism of a tightening machine. The output shaft synchronous pitch-changing mechanism is mainly composed the four parts of a front rotating plate, a rear plate, a central shaft, and a biasing output shaft. The front rotating plate and the rear plate are orderly fixed on the central shaft from front to back. The front rotating plate circles the center of the rear plate to relative rotate. A cam slot which extends along a radial direction is arranged on the front rotating plate, and the cam slot and the biasing output shaft are one-to-one corresponding to each other. A circular arc slot is correspondingly arranged on the rear plate. The working end of the biasing output shaft is tightly clamped on the rear plate and the front rotating plate by the circular arc slot and the cam slot, and extends out the front rotating plate. The structure of the output shaft synchronous pitch-changing mechanism is simple. The output shaft synchronous pitch-changing mechanism can satisfy the tightening of bolts / nuts on at least two reserved circumferences. The simultaneously pitch-changing process of the biasing output shaft is simple, light, and handy, which can improve work efficiency.
Description
Technical field
The utility model relates to the bolt/nut tightening machine, especially the bolt/nut tightening machine output shaft pitch-changing mechanism of wheel of vehicle assembly.
Background technology
At present, the bolt/nut tightening machine output shaft pitch-changing mechanism of wheel of vehicle assembly generally be adopt guide rail or guide groove single shaft one by one the straight line displacement realize the change in location that output shaft directly makes progress, thereby realize that the bolt/nut on the different reference circles tightens.This tightening machine output shaft modified gear structure more complicated, spended time is long during displacement.
Summary of the invention
Become single shaft that huge mechanism the adopts complex structure of displacement structure one by one in order to solve existing tightening machine output shaft, the long shortcoming of spended time during displacement, the utility model proposes the synchronous pitch-changing mechanism of tightening machine output shaft, this mechanism mainly is made up of preceding rotor plate, back plate, center shaft, biasing output shaft four parts.Preceding rotor plate, back plate are fixed on the center shaft from front to back successively, preceding rotor plate can relatively rotate around plate center, back, it is characterized in that: offer the cam path that radially stretches on the preceding rotor plate, the quantity of this cam path is corresponding one by one with the biasing output shaft, the corresponding arc groove that has on the back plate, the working end of biasing output shaft is clamped on back plate, the preceding rotor plate by arc groove, cam path, and stretch out the working end of biasing output shaft rotor plate in the past, and the biasing output shaft also is connected with the back plate by shipping and reselling on another market.When tightening machine output shaft pitch-changing mechanism was positioned at reference position, cam path, the arc groove output shaft of will setovering was clamped in predetermined position, and output shaft is distributed on the circumference, realized tightening of bolt/nut on a kind of predetermined circle; When needing displacement, rotor plate before rotating, before the rotor plate cam path drive a plurality of biasing output shafts pin that rotates simultaneously and turn to the position that needs along the arc groove of back on the plate, the cam path of preceding rotor plate, the arc groove crossover track of back plate has clamped output shaft again, the biasing output shaft is distributed on another predetermined circumference, realizes synchronous displacement, thereby realized tightening of bolt/nut on the another kind of predetermined circle.Described output shaft modified gear is simple in structure, can satisfy tightening of bolt/nut at least two predetermined circle, and the synchronous displacement process of biasing output shaft is simply light and handy, can increase work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that Fig. 1 is along the A-A cutaway view.
Fig. 3 is a kind of working state figure of utility model shown in Figure 1.
The specific embodiment
The synchronous pitch-changing mechanism of tightening machine output shaft as shown in Figure 1, 2, 3, preceding rotor plate 1, back plate 2 are fixed on the center shaft 3 from front to back successively, preceding rotor plate 1 can relatively rotate around plate 2 centers, back, have cam path 4 on the preceding rotor plate 1, to the setover working end of output shaft 6 of the corresponding arc groove 5 that has on the back plate 3, cam path 4, arc groove 5 is clamped in the predetermined track, biasing output shaft 6 also 7 is connected with back plate 3 by shipping and reselling on another market, and the output shaft 6 of setovering is distributed on the circumference D1.During displacement, by active force (as manual, cylinder, or motor) rotates preceding rotor plate 1, cam path 4 drives biasing output shaft 6 and turns to preposition around S. A. 2 along the arc groove 5 on the plate of back, cam path 4, arc groove 5 crossover tracks have clamped biasing output shaft 6 again, and biasing output shaft 6 is distributed on another predetermined circumference D2.
The synchronous pitch-changing mechanism of above-mentioned tightening machine output shaft, by relatively rotating of front and rear panel, and the designed cam path of front and rear panel and the effect of arc groove, the tightening machine output shaft that is distributed on the front and rear panel is moved, thereby change the reference circle size of output shaft, and the tightening machine output shaft is retightened fast by catch gear (can be latch, worm-and-wheel gear or cylinder etc.), so just realized the synchronous displacement of multi-shaft.
Claims (1)
1, the synchronous pitch-changing mechanism of tightening machine output shaft, mainly by preceding rotor plate, back plate, center shaft, biasing output shaft four parts are formed, preceding rotor plate, back plate is fixed on the center shaft from front to back successively, preceding rotor plate can relatively rotate around the back plate, it is characterized in that: offer the cam path that radially stretches basically on the preceding rotor plate, the quantity of described cam path is identical with the quantity of biasing output shaft, the corresponding arc groove that has on the back plate, arc groove is passed through in the working end of biasing output shaft, cam path is clamped on the back plate, on the preceding rotor plate, stretch out the working end of biasing output shaft rotor plate in the past.
