Specific embodiment
Hereinafter reference will be made to the drawings is described in detail by way of example and not limitation some specific embodiments of the present invention.
Identical appended drawing reference denotes same or similar part or part in attached drawing.It should be appreciated by those skilled in the art that these
Attached drawing is not necessarily to be depicted true to scale.
As shown in Figure 1, the utility model provides a kind of positive and negative rotation screw slide, comprising:
Bottom plate 8；
Left support seat 5 and right support seat 10, are relatively fixed on bottom plate 8；
The identical main lead screw 7 of specification is parallel to each other with from lead screw 14 and the left support seat 5 can be arranged in rotation
Between right support seat 10；
Master slider 9 is connect by screw thread with the main lead screw 7, can be by the driving of main lead screw 7 and along the master on bottom plate 8
Sliding rail 6 is toward polyslip；
From sliding block 12, it is connect with described from lead screw 14 by screw thread, it can be by from the driving of lead screw 14 and along on bottom plate 8
From sliding rail 13 toward polyslip；Master slider 9 and the direction of motion from sliding block 12 are opposite always；
The identical driving gear 4 of specification and driven gear 11 stretch out a left side with the main lead screw 7 and from lead screw 14 respectively
One end of support base 5 is fixedly connected, and driving gear 4 and driven gear 11 are intermeshed；
Stepper motor 1 is fixed on the bottom plate 8 by supporting element 2, and passes through shaft coupling 3 and the driving gear 4
It is connected by power.
Again as shown in Fig. 2, being the control system schematic diagram of positive and negative rotation screw slide provided by the utility model, in conjunction with Fig. 1,
Shown in Fig. 2, it is equipped with position instruction block 15 in master slider 9 or from sliding block 12, left limit device 16 and right limit are fixed on bottom plate 8
Position device 17 (such as close switch), the left limit device 16 and right limit device 17 are all connected to electric machine controller 18, the electricity
Machine controller 18 allows hand over the direction of rotation of the stepper motor 1.
When the utility model uses, the main lead screw 7 is identical as the hand of spiral from lead screw 14, and the master slider
It is 9 opposite with the initial position from sliding block 12 (as shown, the initial position of master slider 9 is located at right end, and from sliding block 12 just
Beginning position is located at left end), after stepper motor 1 starts, main lead screw 7 is with the rotation direction from lead screw 14 on the contrary, keeping master slider 9 past
Left sliding, and turning right sliding from sliding block 12 also reaches right end position from sliding block 12 when master slider 9 reaches left end position, from
Position instruction block 15 on sliding block 12 triggers the right limit device 17, and the right limit device 17 sends a signal to electric machine controller
18, electric machine controller 18 then controls the stepper motor 1 and reversely rotates, make master slider 9 with from 12 reverse slide of sliding block, until position
It sets indicator and triggers the left limit device 16, loop back and forth like this.
When the utility model is applied to plunger pump system, the continuous oil pressure plunger pumping system of composition is as shown in Figure 3 (in conjunction with figure
It 1), is that the piston rod of one of two identical plunger pumps 19,20 is separately connected by master slider 9 and from sliding block 12, and two
The oil inlet 23,24 of plunger pump 19,20 is in parallel, and the oil outlet 21,22 of two plunger pumps 19,20 is also in parallel；In this case, when
When one plunger pump 19 is in pressure oil stroke, second plunger pump is then in oil suction stroke, when first plunger pump is switched to suction
When oily stroke, second plunger pump is also switched to pressure oil stroke simultaneously, can make system pressure oil incessantly, realizes continuous pressure
Oil.
Specifically, as shown in figure 3, the piston rod of plunger pump 19 is also moved to the left, at this time when master slider 9 is moved to the left
The check valve that 19 end of plunger pump connects oil inlet 23 is opened, and 19 end of plunger pump connects the closed check valve of oil outlet 21, is made
Plunger pump 19 is in oil suction state, at the same time, moves right from sliding block 12, and the piston rod of plunger pump 20 also moves right, this
When 20 end of plunger pump connection oil inlet 24 closed check valve, 20 end of plunger pump connect oil outlet 22 check valve open,
Plunger pump 20 is set to be in pressure oil state；
When master slider 9 is moved to leftmost position, triggering left limit device 16, electric machine controller 18 then controls the stepper motor
1 reversely rotates, and master slider 9 is changed to move right, and is changed to be moved to the left from sliding block 12, then plunger pump 19 switches to pressure oil shape
State, plunger pump 20 are switched to oil suction state, until master slider 9 is moved to least significant, triggers right limit device 17, then switch again
For state shown in Fig. 3；So in cycles, continuous pressure oil is realized.
It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art
Understand, without departing from the spirit and scope defined by the claims, can many modifications may be made, variation or it is equivalent, but
It falls within the protection scope of the utility model.
