Specific embodiment
Appended drawing reference: 1- piston rod, 2- right-angled trapezium pin, 3- handle part, 4- guide rod, 5- pedestal, 6- groove, 7- connection
Slot.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As in Figure 2-4, the utility model provides a kind of elevation and subsidence regulating device of single pole double-acting piston hydraulic cylinder,
Including piston rod 1, right-angled trapezium pin 2 and guide frame are equipped with groove 6, the right-angled trapezium pin 2 in the middle part of the piston rod 1
It is connected in the groove 6, the right-angled trapezium pin 2 is equipped with link slot 7, and the guide frame is connected in the link slot 7.
As shown in Figure 1, wherein 8 be lifting cylinder, 9 be pallet, and 10 be fixture, and 11 be workpiece, in the prior art, passes through control
Oil pressure in hydraulic cylinder processed, control piston rod rise or fall, and the top of piston rod 1 is connected to load the pallet of workpiece, piston
When bar moves up and down, workpiece is driven to move up and down, when workpiece reaches upper limit, that is to say that piston rod 1 reaches upper limit, added
The fixture of clamping of workpieces will unclamp；And when workpiece reaches lower limit, that is to say that piston rod 1 reaches lower limit, fixture will press from both sides
Clamping of workpieces.But work as certain workpiece, such as when the progress boring cutter processing of cylinder crankshaft hole, it is desirable that workpiece is located at upper limit under
Between limit, then feed workpieces processing, it just not will cause and hit knife or feed situation not in place, the prior art and just can not solve
This problem.
So groove 6 is interior to be provided with one directly as shown in Fig. 2, the utility model opens a groove 6 in the middle part of piston rod 1
The thickness of the trapezoidal pin 2 in angle, the top and bottom of the right-angled trapezium pin 2 is different.By sliding of the guide frame in link slot 7,
The contact thickness change for controlling right-angled trapezium pin 2 and piston rod 1, so that the variation of 1 movement travel of piston rod is realized, so that workpiece
The requirement of processing technology can be met in upper limit, half lifting position and lower limit interdigit free switching.
In the present embodiment, as shown in Fig. 2, being contacted at the top of the right angle end of the right-angled trapezium pin 2 and the groove 6；Institute
Right-angled trapezium pin 2 is stated to slide in the groove 6；The right-angled trapezium pin 2 is vertical with the piston rod 1 to be connect.
As shown in Fig. 2, the right angle end of right-angled trapezium pin 2 is contacted with the top of groove, and the top of right-angled trapezium pin 2
Thickness it is thin, the thickness of bottom is thick, so that is to say bottom and the work of right-angled trapezium pin 2 when right-angled trapezium pin 2 slides into one end
When stopper rod 1 contacts, as shown in figure 3, piston rod is in normal jacking condition, function same as the prior art can be realized, and
When right-angled trapezium pin 2 slides into the other end, that is to say that the top of right-angled trapezium pin 2 and piston rod 1 contact, as shown in figure 4, by
It differs in the thickness of top and bottom close to half, so the stroke of piston rod also can accordingly reduce nearly half, piston at this time
Bar is in half jacking condition, and workpiece can also be in half lifting position, boring cutter can safe feed, then it is right-angled trapezium pin 2 is sliding
It moves to state as shown in Figure 3, workpiece can normally be gone up and down, and carry out next procedure of processing.
In the present embodiment, as shown in Fig. 2, the guide frame includes guide rod 4 and handle part 3, the guide rod 4 with
The handle part 3 connects；The guide rod 4 is connect with the link slot 7；The link slot 7 is arranged in the right-angled trapezium pin 2
Side upper end；The guide frame slides in the link slot 7.
The function of guide frame is the sliding for controlling right-angled trapezium pin 2 in groove 6, by external force in handle part 3
On, then handle part 3 will drive guide rod 4 and slide in link slot 7, to drive the sliding of right-angled trapezium pin 2.The link slot 7
Shape similar to keyway, the side upper end of right-angled trapezium pin 2 is set, and 4 bottom of guide rod is equipped with connection sheet, is connected to link slot
In 7.The effect of handle part 3 is subject to external force, provides stress point, and shape can choose round pie or rod-shaped.
In the present embodiment, as shown in Fig. 2, 1 bottom of the piston rod is equipped with pedestal 5.The utility model can pass through bottom
The bottom of 5 installation of seat in machining center, is fixed.
In actual processing, when employee shifts workpiece onto fixture fixation position, piston rod 1 and right-angled trapezium pin 2 are in Fig. 3
Position (normal lifting position), which puts down workpiece, falls in workpiece dowel hole on positioning pin, is connected to the signal of decline
Afterwards, piston rod 1 is begun to decline, and the pallet for being attached thereto and loading workpiece is driven to drop to extreme lower position, starts work pieces process.When
When being worked into crankshaft hole boring cutter, guide frame movement, while right-angled trapezium pin 2 is pulled, make at right-angled trapezium pin 2 and piston rod 1
In such as position Fig. 4 (half lifting position), rising signals are received at this time, and piston rod 1 begins to ramp up and drives on pallet and workpiece
It is raised to half lifting position (stroke ratio Fig. 3 is small), workpiece is in half lifting position at this time, and cutter can enter workpiece and workpiece is not loose
It opens.After the completion of cutter enters, device receives dropping signal, and piston rod 1 begins to decline extreme lower position, and workpiece is processed.
When entering next processing content after boring cutter completion crankshaft hole machined, guiding rod structure pulls right-angled trapezium pin 2, makes right-angled trapezium pin
2 and piston rod 1 return to extreme lower position.After processing is completed, device receives rising signals to last all the elements, and workpiece is raised to
Upper limit simultaneously unclamps workpiece.Carried out again when processing next workpiece it is above operate, so recycle.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the protection scope of the utility model.
