Embodiment
Please refer to Fig. 1, in a preferred embodiments of the present invention, a kind of stroke limit mechanism based on microswitch, comprise block 11 and a restraint device on a shift fork 10, the rotary part, block 11 on the described rotary part can promote described shift fork 10 along clockwise or be rotated counterclockwise, and described restraint device then limits shift fork 10 along clockwise or the anglec of rotation when being rotated counterclockwise.
Described shift fork 10 arranges at the axial direction of the turning axle of rotary part, the body that tool one is elongated.Described shift fork 10 is tool one shift fork turning axle 6 also, the bearing of trend of shift fork 10 strip bodies and shift fork turning axle 6 axially perpendicular.Shift fork 10 1 ends system is tapered, and the block that this end can be rotated on the parts promotes and make the shift fork rotation, and other end pivot is fixed on the shift fork turning axle 6.
The both sides, below of described shift fork 10 respectively are provided with an elasticity and recover 4, and the block 11 on rotary part breaks away from the promotion of shift fork 10 or when stopping, described elasticity is recovered 4 and promoted shift forks 10 and reset.It is stiff end that described elasticity is recovered 4 one ends, is fixed on an elasticity and recovers on the support 5; The other end is free end, and this free-ended tail end bends to an arc, and described elasticity recovery 4 promotes shift fork 10 by this free end and resets.Under free state, the free end of this elasticity recovery 4 extends obliquely to shift fork 10.
Described restraint device comprises two-stage, first order restraint device is the microswitch restraint device, second level restraint device is the dead retaining of machinery restraint device, partial machinery extremely keeps off restraint device and hinders for some reason or other reasons when not playing a role at the microswitch restraint device of the first order, understand when shift fork 10 continues motion and its collision, reach the purpose that stops its motion
The microswitch restraint device of the first order comprises a sensor pressure surface 1 and two microswitches 3,7.Described two microswitches 3,7 are installed on the fixture 8, and be positioned at the both sides of described shift fork 10, with starting point and the terminal point of respectively corresponding shift fork 10 rotations, described shift fork 10 can trigger microswitch 3 at starting point and the terminal point of its rotation, 7 generation limit signals are spacing to shift fork 10.Described sensor pressure surface 1 is located on the two sides of described shift fork 10 bodies (comprise directly with shift fork 10 bodies two sides as the sensor pressure surface), with axially roughly the paralleling of described shift fork turning axle 6 (comprise the axially not parallel of the part of sensor pressure surface and shift fork turning axle 6, but the sensor pressure surface playing the situation about axially roughly paralleling of that part of and turning axle 6 of the style of work).Described shift fork 10 triggers the microswitch 3,7 of both sides at starting point and the terminal point of its rotation respectively by the sensor pressure surface 1 of shift fork 10 both sides, thereby produces limit signal, carries out spacing to shift fork 10.
Partial machinery extremely keeps off restraint device and comprises the dead retaining 2,9 of two machineries of 10 liang of rotations of corresponding shift fork limit respectively.When microswitch 3 is not triggered limit signal when spacing to shift fork 10, shift fork 10 continues athletic meeting and bumps against with the dead retaining 2,9 of machinery and stop motion.The dead retaining 2,9 of two machineries also is installed on the fixture 8, is positioned at the both sides of described shift fork 10, and is rotated the end that the block 11 on the parts promotes near shift fork 10.Form a V-arrangement space between the dead retaining 2,9 of two machineries, only allow that shift fork 10 is rotated in this V-arrangement space.
The parts of the stroke limit mechanism in the present embodiment tie up on the axial direction of turning axle of rotary part and arrange, under the constant situation of functions of use, do not take the radial space of structure, be fit to be applied to the strict environment of radial space, as be applied in the robot of clean environment.
