Abstract
The invention provides a servomotor with an automatic hydraulic locking function. A locking piston rod is sleeved with a locking cylinder, the lateral surface of the locking piston rod is provided with a hole, the lateral surface of the locking cylinder is provided with a hole, a connector is installed in the hole in the locking cylinder, a limiting pin and a spring are installed in a connector hole, a supporting frame is installed at the bottom of the outer side of the locking cylinder and connected with the limiting pin through a lever, one end of the lever is hinged to the supporting frame, the other end of the lever is hinged to the limiting pin, a protrusion is arranged on the lower portion of the lever, a supporting rod is fixedly installed on a hoisting lug and fixedly provided with a long bolt, and the axis of the long bolt passes through the protrusion of the lever. The locking hydraulic cylinder is installed on the servomotor, when the servomotor reaches the needed stroke, the locking hydraulic cylinder will automatically extend out to lock the piston rod, the locking purpose is realized, and the servomotor with the automatic hydraulic locking function is simple in structure, is accurate in stroke control and avoids wrong operations.
Description
Technical field
The present invention relates to servomotor technical field, especially a kind of servomotor with automatic hydraulic lock function.
Background technique
Conventional hydraulic locking servomotor is the detection by sensor, after servomotor reaches the position of setting, manually fingertip control locking oil hydraulic cylinder, reach the object of lock piston bar, cost due to sensor is current still very expensive, and there will be error, will produce misoperation like this, the position causing servomotor not reach wanting just has locked, and easily breaks piston rod.
Summary of the invention
The technical problem to be solved in the present invention is: accurately control the position of servomotor and lock oil hydraulic cylinder.In order to solve the problem, provide a kind of servomotor with automatic hydraulic lock function.
The technical solution adopted for the present invention to solve the technical problems is: a kind of servomotor with automatic hydraulic lock function, described servomotor is provided with hydraulic locking mechanism, described hydraulic locking mechanism comprises lock piston bar, locking cylinder, joint, spring, position limit pin, lever, support, stay bolt, pole, described lock piston bar is sleeved in locking cylinder, lock piston bar side face has a hole, described locking cylinder has a hole in the position corresponding with the hole on lock piston bar, in the hole of described jiont treatment on locking cylinder, position limit pin and spring fitting are in the hole of joint, described support is arranged on locking cylinder exterior bottom, support is connected by lever with position limit pin, described lever one end and support hinged, the other end and position limit pin hinged, lever bottom is provided with a projection, described pole is fixedly mounted on hanger, pole fixedly mounts stay bolt, the axis of stay bolt is through the projection of lever.
The invention has the beneficial effects as follows: locking oil hydraulic cylinder is installed on servomotor, will automatically allow when servomotor reaches required stroke locking oil hydraulic cylinder stretch, lock piston bar, reach the object of locking, structure is simple, and Stroke Control is accurate, can not produce misoperation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of hydraulic locking mechanism of the present invention;
Fig. 2 is the schematic diagram of servomotor of the present invention when being in locked position;
Fig. 3 is A place enlarged view in Fig. 2.
In figure: 1, lock piston bar, 2, locking cylinder, 3, joint, 4, spring, 5, position limit pin, 6, lever, 7, support, 8, hanger, 9, stay bolt, 10, pole, 11 is protruding.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Embodiment
A kind of servomotor with automatic hydraulic lock function, servomotor is provided with hydraulic locking mechanism, hydraulic locking mechanism comprises lock piston bar 1, locking cylinder 2, joint 3, spring 4, position limit pin 5, lever 6, support 7, stay bolt 9 and pole 10, lock piston bar 1 is sleeved in locking cylinder 2, lock piston bar 1 side face has a hole, locking cylinder 2 has a hole in the position corresponding with the hole on lock piston bar 1, joint 3 is arranged in the hole on locking cylinder 2, position limit pin 5 and spring 4 are arranged in joint 3 hole, support 7 is arranged on locking cylinder 2 exterior bottom, support 7 is connected by lever 6 with position limit pin 5, lever 6 one end and support 7 hinged, the other end and position limit pin 5 hinged, lever 6 bottom is provided with a projection 11, pole 10 is fixedly mounted on hanger 8, pole 10 fixedly mounts stay bolt 9, the axis of stay bolt 9 is through the projection 11 of lever 6.
As shown in Figure 1, first allow lock piston bar 1 be in and do not stretch out state, in normal circumstances position limit pin 5 in next straight cutting of effect of spring 4 hole of lock piston bar 1, lock piston bar 1 cannot be stretched, then when servomotor moves to total travel, the stay bolt 9 be contained on servomotor hanger 8 will encounter the projection 11 of lever 6, lever 6 is hinged with position limit pin 5, thus drive position limit pin 5 to move, when position limit pin 5 moves a certain distance, will be gone out of lock piston rod 1, lock piston bar 1 is stretched (as shown in Figure 2) under the effect of oil pressure, reach the object automatically locking piston rod 1.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
