Description
Technical field
The utility model relates to the upset work piece holder of machining, the frame for movement of 90 ° of degree of a kind of reciprocating rotating.
Background technology
On the machining production line, often need workpiece or anchor clamps be turned round (or upset) 90 °.This needs often add pinion and rack through servomotor, angling cylinder and straight line oil cylinder and drive and realize.
1. the motion of driven by servomotor slew gear is steady, but cost is high;
2. the straight line oil cylinder adds pinion and rack to drive cost low, but impacts when starting and stopping greatly, often damages parts and the location is inaccurate.
Angling cylinder mechanism drives cost and is lower than the driven by servomotor slew gear, is higher than the straight line oil cylinder and adds pinion and rack and drive, and keeps away unavoidable startup equally and impacts when stopping greatly, often damages the inaccurate problem of parts and location.
Summary of the invention
The purpose of the utility model provides a kind of sinusoidal sheave switching mechanism, and the angle of revolution is 90 °, and its cost is low, start and stop steadily, accurate positioning is reliable.
The design's sinusoidal sheave switching mechanism comprises driving box, straight line oil cylinder, and the driving box internal upper part that it is characterized in that being fixed on the basis is installed trip shaft through bearing, and the turnover bracket in left side is fixed on the trip shaft; Through bearing the gear shaft parallel with trip shaft is installed at the driving box middle part, fixed gear and fork on gear shaft, the tooth bar engagement that gear connects with straight line oil cylinder piston bar, the straight line oil cylinder is positioned at the driving box bottom; Roller is equipped with in end at fork, and former is fixed on the trip shaft, and the radially straight trough on the external cylindrical surface of roller and the former is slidingly matched, and can move along the straight trough on the former; Rectilinear motion through gear, tooth bar adjutant straight line oil cylinder changes gyration into, incites somebody to action at the uniform velocity gyration through sinusoidal sheave structure again and becomes the speed change gyration.
The beneficial effect of the utility model: in the upset clamping apparatus, designed the sinusoidal sheave switching mechanism that Geneva mechanism is arranged; Drive the switching mechanism compared with techniques with in the past straight line oil cylinder, pinion and rack; Its start, stop action very steadily, do not have impact, accurate positioning, have wide practical value making production field.

Fig. 2 is the A-A face expanded view of sinusoidal sheave switching mechanism;
Fig. 3 is the angle of revolution relation curve of gear shaft and trip shaft;
Fig. 4 is the solid figure of former.
The specific embodiment
Sinusoidal sheave switching mechanism; Comprise driving box, straight line oil cylinder, referring to Fig. 1,2: it is characterized in that driving box 5 is installed on the fixed basis, its left side is a turnover bracket 6; Through bearing trip shaft 10 is installed on driving box 5 tops, turnover bracket 6 is fixed on the trip shaft 10; Through bearing the gear shaft 3 parallel with trip shaft 10 is installed at the middle part of driving box 5; Fixed gear 4 and fork 9 on gear shaft 3, tooth bar 2 engagements that gear 4 connects with straight line oil cylinder 1 piston rod, straight line oil cylinder 1 is positioned at driving box 5 bottoms; In the end of fork 9 roller 8 is housed, former 7 is fixed on the trip shaft 10, and the radially straight trough on the external cylindrical surface of roller 8 and the former 7 is slidingly matched, and can move along the straight trough on the former 7.
As can be seen from Figure 4; The width of the working portion of the radially straight trough on the former 7 is identical with the outside dimension of roller 8; Adopt matched in clearance between them, be modified to gradually open arc face in the two sides of straight trough bottom, consistent with the gyration track of roller 8 cylindrical buses; Guaranteeing can not influence the location of turnover bracket when roller 8 surpasses the angle of revolution of setting.
This working process of mechanism is: move right when the 1 left end oil-feed of straight line oil cylinder promotes tooth bar 2, driven gear 4 is around gear shaft 3 revolutions, and gear shaft 3 drives fork 9 and gear 4 revolution synchronously counterclockwise; Be contained in roller 8 on the fork 9 and stir former 7, drive trip shaft 10 in the lump and clockwise rotate to 90 ° of positions, trip shaft 10 drags turnover bracket 6 and accomplishes 90 ° of upsets clockwise.Be moved to the left when the 1 right-hand member oil-feed of straight line oil cylinder promotes tooth bar 2, driven gear 4 is around gear shaft 3 revolutions, and gear shaft 3 drives fork 9 and gear 4 revolution synchronously clockwise; Be contained in roller 8 on the fork 9 and stir former 7 and drive trip shafts 10 and rotate counterclockwise to 90 ° of positions, trip shaft 10 drags turnover bracket 6 and accomplishes counterclockwise flip-flop movement.
The core of the utility model is to change linear uniform motion the gyration of turnover bracket by sinusoidal variation into through the Geneva mechanism of uniqueness, and its curve movement is seen Fig. 3, makes that trip shaft is zero starting and stop moment its angular speed.And trip shaft revolution is between 0 °～45 ° the time, and its angular speed is to be quickened by zero angle speed by sine curve; In the time of between 45 °～90 °, be decelerated to zero angle speed, eliminated the impact phenomenon when starting and stopping of turnover bracket fully by sine curve.Radially straight trough bottom on the former 7 has been done outside the working region with the consistent cambered surface of gyration track of roller 8 cylindrical buses and has been repaiied type; When even if fork 9 has overshoot phenomenon 0 °, 90 ° position; Also can not influence the accurate location of turnover bracket, so positioning accuracy is very high.
