Abstract
The utility model provides a gear eccentric gap removing mechanism for a numerical control cutting machine. An eccentric sleeve is hinged to a machine body, a speed reducing motor is fixed on the eccentric sleeve, a transmission gear is installed on a motor output shaft of the speed reducing motor, a rack is installed on a machine body guide rail, and a press cover is fixed on the machine body through a connection piece. The gear eccentric gap removing mechanism has the advantages of removing lateral gaps of a gear rack pair through adjustment and control, improving transmission accuracy and the like and effectively prolongs service life of the numerical control cutting machine. The gear eccentric gap removing mechanism is suitable to serve as an application of a transmission mechanism and other gear rack transmission mechanisms of the numerical control cutting machine.
Description
Technical field
The utility model provides a kind of transmission anti-backlash mechanism of the numerical control cutting machine in the machine building industry, specifically the eccentric anti-backlash mechanism of numerical control cutting machine gear.
Background technique
Traditional numerical control cutting machine driving mechanism generally is the transmission of exposed gear tooth bar, under the precision prescribed condition with higher, conventional rack-and-pinion fixed interval (FI) Placement can't satisfy the requirement on machining accuracy of lathe, occurs the overproof situation in gear rack clockwise and anticlockwise gap often; And along with the growth in lathe life-span, backlash is increasing, causes cutting accuracy to reduce.
Summary of the invention
In order to overcome the secondary defective that connects of existing numerical control cutting machine middle gear tooth bar, the utility model provides a kind of numerical control cutting machine gear eccentric anti-backlash mechanism.This mechanism is by being provided with the gear off-centre crack bindiny mechanism that disappears, and it is excessive and adjust backlash and be difficult for the technical problem adjusted to solve the rack-and-pinion backlash.
The scheme that the utility model technical solution problem adopts is:
Eccentric bushing is hinged on the fuselage, and reducing motor is fixed on the eccentric bushing, and driving gear is installed on the reducing motor output shaft, and tooth bar is installed on the fuselage guide rail, and gland is fixed on the fuselage by link.
Good effect the utlity model has and adjusts control elimination rack-and-pinion sideshake, improves advantages such as transmission accuracy, the working life of effectively improving numerical control cutting machine.Suitable application as numerical control cutting machine driving mechanism and other rack and pinion drive mechanism.
Description of drawings
Fig. 1 is the utility model structural drawing
Fig. 2 is the utility model plan view
Fig. 3 is the utility model left view
Among the figure, 1. fuselage, 2. fuselage guide rail, 3. reducing motor, 4. eccentric bushing, 5. gland,
6. tooth bar, 7. driving gear.
Embodiment
According to the figure, eccentric bushing 4 is hinged on the fuselage 1, and reducing motor 3 is fixed on the eccentric bushing, and driving gear 7 is installed on the reducing motor output shaft, and tooth bar 6 is installed on the fuselage guide rail 2, and gland 5 is fixed on the fuselage by link.
The utility model working procedure:
In the production assembly process, adjust eccentric bushing by rotating, the spacing of driving cog wheel and rack is changed, reduce the meshing backlass of rack-and-pinion, thereby reach the effect of eliminating drive gap; After numerical control cutting machine uses a period of time, also can eliminate the drive gap that produces because of the rack-and-pinion meshing wear by said method.
Characteristics:
The utility model can be adjusted control and eliminate the rack-and-pinion sideshake, improves transmission accuracy, the working life of effectively improving numerical control cutting machine, and accurate positioning cutting machine is operated steadily, and it is strong to have stability, the advantage that machining accuracy is high.
