Abstract
The invention relates to cutting equipment, in particular to a gear drive protection device for a cutting machine, which comprises a machine frame. A gear and a rack which are mutually meshed are arranged on the machine frame; a reduction gear base is elastically connected with the machine frame in the horizontal direction; a spring is arranged on the joint face between the reduction gear base and the machine frame; a screw rod is fixedly arranged on the machine frame; one end of the screw rod stretches into the reduction gear base; the spring is sleeved on the screw rod; a spring gland used for tightly compressing a pressure spring is arranged at the end of the screw rod; and the reduction gear base is connected with the machine frame through a rotary bracket. Because of the adoption of an elastic connection way, the gear drive protection device of the invention makes the movement of a machine more precise; in a movement process, backlash does not appear on the gear and the rack, so the quality of a cut product is greatly improved and the mechanical properties of the structure are strengthened; and in addition, the gear drive protection device has convenient assembly and reliable performance, meets the stability of vertical traveling, improves the quality of the product and brings good economic benefit and social effect.
Description
Technical field
The present invention relates to a kind of cutting equipment, especially a kind of gear drive protection device for cutting machine.
Background technology
The cutting machine employing rack and pinion drive mechanism of vertically walking because of lathe cutting accuracy and the requirement of motion leveling style, should this must guarantee closely cooperating of rack-and-pinion.Before, adopt the common mode that is rigidly connected usually, promptly reductor is contained on the mount pad, and gear cooperates installation with reductor, from bottom fixed gear and reductor, then mount pad directly is fixed on the cutting machine vehicle frame outside with screw with screw.The workman will carry out meticulous adjustment when mounted, realizes the wheel and rack good engagement.
Because it is to be rigidly connected that rack-and-pinion cooperates, and reach both closely cooperating, just require the mount pad machining accuracy of reductor to want high, adjust during installation, could guarantee that rack-and-pinion meshes fully.
Though drives structure is simple, workpiece accuracy is had relatively high expectations, install complicated.And when the wheel and rack cooperation was gapped slightly, machine just was easy to generate backlass, influences cut quality during backhaul.Behind the long-play, rack-and-pinion all is prone to more serious wearing and tearing; When machine runs into shock loading, also cause rack-and-pinion to be hit power and to damage distortion.
Summary of the invention
Damage for the rack-and-pinion of cutting machine being carried out effective protecting against shock, the invention provides a kind of gear drive protection device for cutting machine.
According to the machine operational effect, the cutting products quality, and the workman installs situations such as complexity, we carry out vertical driving mechanism and improve.Do the most basic change from the connection of rack-and-pinion, becoming is rigidly connected is the elasticity connection.Thereby flexibly adjust wheel and rack, make to reach the cooperation of no gap.Elasticity connects the surge protection effect of also playing simultaneously.
Purpose of the present invention is achieved through the following technical solutions: a kind of gear drive protection device for cutting machine; has frame; frame is provided with pitch wheel and tooth bar; gear passes through planet gear drives by the servomotor of top; be provided with reducer pedestal below planetary, described reducer pedestal and frame elasticity in the horizontal direction are connected.
Particularly: the composition surface of described reducer pedestal and frame is provided with spring, is set with screw rod on frame, and an end of screw rod stretches into reducer pedestal inside, and spring housing is contained on the screw rod, is provided for compressing the spring capping of stage clip in the screw rod end.
For reducer pedestal is effectively supported, make simultaneously to produce between rack-and-pinion to have certain elasticity adjustment surplus when impacting, make gear find the position that cooperates fully with tooth bar, more further: described reducer pedestal is connected by runing rest with frame.
The present invention adopts the elasticity ways of connecting, though increased some part is installed, and makes the motion of machine more accurate, in motion process, rack-and-pinion backlass can not occur, has improved the quality of cutting products greatly, and has strengthened the mechanical performance of structure.In addition, easy to assembly, dependable performance satisfies the vertically stationarity of walking, and product quality improves, and has obtained using the consistent favorable comment of producer, produces good economic benefit and social effect.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is another angle structural representation of the present invention.
Among the figure: 1. frame 2. gears 3. tooth bars 4. servomotors 5. planetary gears 6. reducer pedestals 7. springs 8. screw rods 9. spring cappings 10. runing rests
The specific embodiment
A kind of gear drive protection device for cutting machine as shown in Figure 1 and Figure 2; has frame 1; frame 1 is provided with pitch wheel 2 and tooth bar 3; gear 2 is driven by planetary gear 5 by the servomotor 4 of top; be provided with reducer pedestal 6 below planetary gear 5, described reducer pedestal 6 and frame 1 elasticity in the horizontal direction are connected.Particularly, described reducer pedestal 6 is provided with spring 7 with the composition surface of frame 1, is set with screw rod 8 on frame 1, and an end of screw rod 8 stretches into reducer pedestal 6 inside, spring 7 is sleeved on the screw rod 8, is provided for compressing the spring capping 9 of stage clip 8 in screw rod 8 ends.
Structure of the present invention is that a runing rest 10 is installed in frame 1 outside, and on runing rest 10, it can rotate around vertical axis reducer pedestal 6 integral installations.So just can rotate support 6 arbitrarily, driven gear 2 finds the position that cooperates fully with tooth bar 3, makes gear 2 tooth bars 3 reach the engagement of no gap.Most critical be, a multi-processing part on reducer pedestal 6, it can install a spring 7, adopts screw rod 8 to link to each other with frame 1 then, the function of spring 7 can be pressed on gear 2 on the tooth bar 3, and they are closely cooperated.The no gap that has so not only reached gear 2 tooth bars 3 cooperates, and when machine was subjected to impulsive force, gear 2 can be deviate from tooth bar 3, thereby has protected driving parts.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
