Detailed description of the invention
In order to make content of the present utility model be easier to be clearly understood, below according to specific embodiment and combine accompanying drawing, this utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of driving indexing mechanism, it includes indexing mechanism body 5, and ratchet 3, movable cylinder 1 and the spring lifting block being arranged on indexing mechanism body 5；
Ratchet 3 is fixing with the motion bar of movable cylinder 1 to be connected, and moves under the drive of motion bar, and ratchet 3 is the most uniformly installed four pulleys 14；
The top of spring lifting block is against on pulley 14, and by pulley 14, spring lifting block extrudes moving up and down of control spring lifting block.
Preferably, as it is shown in figure 1, be also equipped with for stoping the counter-rotational ratchet of ratchet 34 on indexing mechanism body 5, ratchet 4 orients spline to ratchet, makes ratchet 3 to be rotated in the clockwise direction.
Preferably, indexing mechanism body 5 is provided with guide-track groove, and ratchet 3 is slidably mounted on guide-track groove by a slide block 2, and slide block 2 is connected with the motion bar of movable cylinder 1, and moves left and right along guide-track groove under the drive of motion bar, and ratchet 4 is also mounted on above-mentioned slide block 2.
Alternatively, as in figure 2 it is shown, the central axis of ratchet 3 is installed with the output shaft 11 for exporting ratcheting action, output shaft 11 positions on ratchet 3 and is screwed together, installing workpiece to be held by output shaft 11, drives workpiece to be held to rotate together.
Preferably, as shown in Figure 1 and Figure 2, spring lifting block includes elevator 8, moving leader 7 and spring 6；
Elevator 8 is fixedly connected on the top of moving leader 7；
The lower end of spring 6 is connected on indexing mechanism body 5, and upper end is connected on moving leader 7.
Further, indexing mechanism body 5 is provided with spline pin 9, and one end of elevator 8 has the through hole matched with spline pin 9, and spline pin 9 is actively plugged in above-mentioned through hole, spline pin 9 is used for preventing elevator 8 from rotating and guiding elevator 8, makes elevator 8 only move at vertical direction.
Alternatively, indexing mechanism body 5 have for through moving leader 7 through hole that moving leader 7 is guided, being fixed with guide pin bushing 13 in through hole, for reducing the friction of moving leader 7 and indexing mechanism body 5.
Specifically, as in figure 2 it is shown, ratchet 3 is fixed on slide block 2 by axial screw 10, described pulley 14 is fixed on ratchet 3 by axial screw 10.
Further, pulley 14 is provided with four, is distributed as pulley a, pulley d, pulley b, pulley e, and the central angle that adjacent two pulley 14 place circular arcs are corresponding is 90 °, so that ratchet 3 often completes once to index, and half-twist；Certainly pulley 14 can also be provided with five or six or eight according to actual needs, by changing the number of pulley 14, and the one stroke of the movable cylinder matched with pulley number and then change the anglec of rotation of index pawl 3 each time.
Movable cylinder 1 is cylinder, it is of course possible to for hydraulic cylinder.
Operation principle of the present utility model is as follows:
As shown in Figure 1, when the motion bar of cylinder 1 stretches out, slide block 2 is promoted to be moved to the left with the ratchet 3 on slide block 2, pulley d on ratchet 3 extrudes elevator 8, elevator 8 is made to be always positioned at below pulley d, till pulley d disengages with elevator 8, when pulley d departs from elevator 8, elevator 8 is by moving leader 7 upwards lifting certain distance under the effect of spring 6, and now pulley d is stuck on the left of elevator 8；
When the motion bar of cylinder 1 is retracted, motion bar pulls slide block 2 to move right with the ratchet 3 on slide block 2, pulley d on ratchet 3 is limited by elevator 8 and can not be moved to right with ratchet 3, pulley d is stuck on the left of elevator 8, ratchet 3 is caused to move in the direction of the clock together with output shaft 11 fixed thereon, until pulley b is pressed on elevator 8 and extrudes elevator 8 and progressively declines, along with the motion bar of cylinder continues to retract, pulley d starts to slide onto elevator 8, so that pulley d lifts restrictions, ratchet 3 and output shaft 11 are not rotated further by, jointly move right to stopping along elevator 8 upper surface, at this moment pulley d arrives the position of a, pulley b arrives the position of d, complete once to index.
This utility model uses the push pull maneuver of conventional movable cylinder 1 to coordinate the ratchet 3 with pulley 14 to complete rev indexing, and by ratchet, ratchet is oriented spline, makes ratchet 3 to be rotated in the clockwise direction；This utility model by changing the number of pulley 14, and the one stroke of the movable cylinder matched with pulley number, thus can change the anglec of rotation of index pawl 3 each time simply and easily；This utility model simple in construction, machining cost is low, and position control is more convenient.
Particular embodiments described above; solve the technical problem that this utility model, technical scheme and beneficial effect are further described; it is it should be understood that; the foregoing is only specific embodiment of the utility model; it is not limited to this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, within should be included in protection domain of the present utility model.
