Abstract
The utility model provides a gear flexible gap eliminating mechanism of an NC cutting machine. An adjusting support is connected to a machine body, one end of a reducer support is hinged to the adjusting support through a hinge pin, a planetary reducer (4) is fixedly connected with the reducer support, a gear is connected with the planetary reducer, and the other end of the reducer support is connected with the machine body through a compression bolt and a compression spring. A guide rail is arranged below the machine body, and a rack is fixedly arranged on the side face of the machine body. The gear flexible gap eliminating mechanism of the NC cutting machine has the advantages of automatically eliminating side gaps of a gear rack pair, improving cutting precision, preventing the gear rack pair and a transmission reducer from being damaged accidentally, effectively prolonging the service life of the cutting machine, and being suitable for a transmission mechanism and other gear rack transmission mechanisms of the NC cutting machine.
Description
Technical field
The utility model provides a kind of transmission anti-backlash mechanism of the numerical control cutting machine in the machinery manufacturing industry, specifically the flexible anti-backlash mechanism of numerical control cutting machine gear.
Background technology
Traditional cutting machine transmission mechanism generally is the transmission of exposed gear tooth bar, and adopts hardwired type of attachment, because cutting environment is comparatively abominable, occurs rack-and-pinion often and presss from both sides the into situation of foreign matter, causes the damage of rack-and-pinion or transmission speed reducer.
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 flexible anti-backlash mechanism.This mechanism solves the technical problem of rack-and-pinion or transmission speed reducer damage by being provided with the gear flexible linking device.
The scheme that the utility model technical solution problem adopts is:
Adjusting bearing is connected on the fuselage, reductor support one end is hinged with the adjustment bearing by bearing pin, planetary reducer is fixedlyed connected with the reductor support, gear is connected with planetary reducer, the reductor support other end is connected with fuselage by hold-down bolt and holddown spring, guide rail places under the fuselage, and tooth bar is fixed in the fuselage side.
Good effect the utlity model has automatic elimination rack-and-pinion sideshake, improves cutting accuracy, prevents the advantage of the unexpected damage of rack-and-pinion and transmission speed reducer, the service life of effectively improving cutting machine.Suitable application as numerical control cutting machine transmission mechanism and other rack and pinion drive mechanism.
Description of drawings
Fig. 1 is the utility model structure chart
Among the figure, 1. fuselage, 2. guide rail, 3. tooth bar, 4. planetary reducer, 5. gear,
6. bearing pin is 7. adjusted bearing, 8. reductor support, 9. hold-down bolt, 10. spring.
The specific embodiment
According to the figure, adjusting bearing 7 is connected on the fuselage 1, reductor support 8 one ends are hinged with the adjustment bearing by bearing pin 6, planetary reducer 4 is fixedlyed connected with the reductor support, gear 5 is connected with planetary reducer, the reductor support other end is connected with fuselage by hold-down bolt 9 and holddown spring 10, and guide rail 2 places under the fuselage, and tooth bar 3 is fixed in the fuselage side.
The utility model course of work:
Under the normal operation, gear is subjected to the effect of pressing force of the spring, is pressed on the tooth bar, thereby reaches the effect of eliminating drive gap; When sandwiching foreign matter between the rack-and-pinion, its extruding force overcomes spring force and wheel and rack is thrown off automatically, thereby realizes protecting rack-and-pinion or transmission speed reducer to avoid damaging.
Characteristics:
The utlity model has automatic elimination rack-and-pinion sideshake, improve cutting accuracy, prevent advantages such as the unexpected damage of rack-and-pinion and transmission speed reducer, make the cutting machine stable and reliable operation service life of effectively improving cutting machine, the machining accuracy height.
