Abstract
The invention relates to a reciprocating linear motion mechanism. A closed internally-toothed guide rail consists of two toothed racks and two semi-circular internally-toothed rings and is fixed on a work bench with a linear guide rail. A driving shaft is connected with a driving mechanism. A driving gear is fixedly connected with the driving shaft. A wheel axle support frame is connected with the driving shaft, an intermediate gear and a guide wheel. The intermediate gear engages with the internal teeth of the driving gear and the closed internally-toothed guide rail respectively. The guide wheel is matched with the external rail of the closed internally-toothed guide rail and can roll along the external rail of the closed internally-toothed guide rail. The driving mechanism supplies power to the driving gear via the driving shaft and then acts on the closed internally-toothed guide rail via the intermediate gear. Under the limitation of the guide wheel, the intermediate gear makes cyclic motion along the closed internally-toothed guide rail, thereby driving the work bench to make reciprocating linear motion. The mechanism is characterized in large travel range, uniform velocity, smooth turning and no need of limit switch; and is suitable for mechanical equipment in need of uniform-velocity and large-travel reciprocating linear motion.
Description
Technical field
The present invention relates to a kind of reciprocating linear motion mechanism, particularly a kind of traverse scope is big, speed even and the level and smooth reciprocating linear motion mechanism that commutates.
Background technique
The existing driving mode of linear reciprocating motion that realizes roughly has following several mode: the fluid kind of drive comprises hydraulic transmission and air pressure driving mechanism; Slidercrank mechanism; Bolt and nut mechanism; Pinion and rack.
Respectively there are pluses and minuses in these mechanisms, and wherein the fluid driving mechanism has the easy advantage of commutation, but need install various dynamical elements, executive component, control unit, auxiliary element and working medium etc. additional, and the element accuracy of manufacturing requires high; Slidercrank mechanism also has commutation and is easy to advantage, but exists traverse limited, and defective such as speed is inhomogeneous; Though bolt and nut mechanism and the pinion and rack motion speed is even, traverse is big need install reversing arrangement additional and limit switch is set.
Summary of the invention
In order to overcome above-mentioned deficiency, the invention provides the reciprocating linear motion mechanism that a kind of traverse scope is big, speed even, commutation smoothly and not needs limit switch.
For realizing above purpose, the technical solution adopted in the present invention comprises equipment and transmitting assemblies.Equipment is made up of worktable that has linear rail and the closed internal tooth guide rail of being made up of two toothed rack and two semicircle ring gears that is fixed on the worktable, and transmitting assemblies comprises assemblies such as driving mechanism, live axle, actuation gear, intermediate gear, guide wheel, wheel shaft supporting frame.Live axle connection driving mechanism and its axis normal are in plane, closed internal tooth guide rail place, intermediate gear and guide wheel are installed in respectively on the wheel shaft of wheel shaft supporting frame, the wheel shaft supporting frame connects live axle, intermediate gear respectively with the engagement of the internal tooth of actuation gear and closed internal tooth guide rail, guide wheel cooperates with closed internal tooth guide rail outer rail, can roll along the outer rail of closed internal tooth guide rail.Driving mechanism is transported to actuation gear with power by live axle, act on the closed internal tooth guide rail by intermediate gear again, because the effect of contraction of guide wheel, intermediate gear will be done shuttling movement along closed internal tooth guide rail, do linear reciprocating motion thereby drive worktable.
The invention has the beneficial effects as follows that it has, and the traverse scope is big, speed even, commutation smoothly and not needs characteristics such as limit switch, is applicable to the various machinery that at the uniform velocity reach the requirement of big traverse linear reciprocating motion that have.

Embodiment
Also the invention will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1 and Figure 2:
Closed internal tooth guide rail (6) is fixed in worktable (3), driving mechanism (1) is fixed in pedestal (9), actuation gear (4) is fixedlyed connected with live axle (10), intermediate gear (5) and guide wheel (7) are installed in respectively on the wheel shaft (8) of wheel shaft supporting frame (2), wheel shaft supporting frame (2) is connected with live axle (10), intermediate gear (5) meshes with actuation gear (4) and closed internal tooth guide rail (6) respectively, and guide wheel (7) cooperates with closed internal tooth guide rail (6) outer rail.
During work, driving mechanism (1) is transported to actuation gear (4) with power by live axle (10), acts on the closed internal tooth guide rail (6) by intermediate gear (5) again.Because the effect of contraction of guide wheel (7), intermediate gear (5) will be done shuttling movement along closed internal tooth guide rail (6), do linear reciprocating motion thereby drive worktable (3).
