If Fig. 1 is the structure chart for the switching mechanism that present embodiment provides, switching mechanism includes riser 1 and is fixed on riser
Lifting assembly 2, overturning component 4, clamp assembly 5 and buffer limit component 3 on 1.Wherein, lifting assembly 2 is fixed with riser 1,
And be connected with clamp assembly 5, lifting assembly 2 can drive overturning component 4 to be moved up and down on riser 1；Overturning component 4 connects
Clamp assembly 5, clamp assembly 5 fix workpiece, and overturning component 4 can drive clamp assembly 5 to rotate, by lifting assembly 2 and turn over
Turn the cooperation of component 5, can realize the lifting and rotation of workpiece, so as to facilitate workpiece motion s to overturning after appropriate height.
Specifically, lifting assembly 2 can include lifting cylinder 21, and lifting cylinder 21 is fixed on riser 1, lifting cylinder 21
Output terminal be connected with overturning component 4, the up and down motion of component 4 is overturn by the flexible realization of the output terminal of lifting cylinder 21,
So as to which the workpiece being clamped on clamp assembly 5 be driven to carry out elevating movement.
For the support lifting cylinder for stablizing riser 1, lifting assembly 2 can also include cylinder supports platform 23, cylinder
Supporting table 23 is fixedly connected with riser 1, and the support plate of vertical wall 1 is convexly equipped on cylinder supports platform 23, and lifting cylinder 21 is fixed
In being provided with through hole in support plate, support plate, the output terminal of lifting cylinder 21 is pierced by by through hole.Lifting cylinder 21 is located at cylinder branch
It supports the lower section of platform 23 and outputs it the through hole in end stretches out cylinder supporting table 23, the thrust by lifting cylinder 21 will overturn group
Part 4 jacks up, and passes through the pulling force of the dead weight for overturning component 4 and lifting cylinder 21 or support force declines, and elevating movement is more steady.
In the lifting process of switching mechanism, running into some emergencies needs emergency stop to be taken to operate equipment, and equipment is anxious
Stopping time switching mechanism may fall suddenly.Therefore, guiding one-way valve is also provided on lifting cylinder 2, in equipment emergency stop
Triggering, for keeping the position of the output terminal of lifting cylinder 21, prevents it from falling suddenly, switching mechanism when solving equipment emergency stop
The security risk to fall suddenly.
Lifting assembly 2 output terminal connection overturning component 4, overturning component 4 can under the driving of lifting assembly 2 on move down
It is dynamic.
It is not susceptible to shake to make the lifting of overturning component 4 more steady, in operational process, it is specific in lifting assembly 2
There is provided sliding part 22, sliding part 22 is connected respectively with overturning component 4 and lifting cylinder 21, in sliding part 22 and 1 the two of riser,
Any one is provided with slide along the lifting direction of lifting assembly 2, another is provided with the sliding slot with slide cooperation.As a kind of excellent
Mode is selected, is specifically as follows：Multiple sliding blocks are provided on sliding part 22, a plurality of slide is provided on riser 1, is provided on sliding block
With the sliding slot of slide cooperation, sliding block is realized by sliding slot and is slidably connected with slide.By setting sliding part 22, component 4 is overturn
Lifting be subject to constraint on vertical direction, will not shift in lifting process, more stable lifting.
It overturns and clamp assembly 5 is connected on component 4, clamp assembly 5 can be overturn under the driving of overturning component 4.For reality
The overturning of existing clamp assembly 5, overturning component 4 are made of tumble cylinder 41 and clamping brace plate 42, the fixing end of tumble cylinder 41
It is fixed with sliding part 22, output terminal is connected by clamping brace plate 42 with clamp assembly 5, makes folder by the rotation of its output terminal
Tight component 5 rotates.
Clamp assembly 5 is made of clamping cylinder 51 and clamping jaw 52, and clamping cylinder 51 is connected on clamping brace plate 42, is passed through
The overturning of clamping brace plate 42 drives clamping cylinder 51 to overturn；The jaw plate that clamping jaw 52 is oppositely arranged by two forms, jaw plate
Be connected with the output terminal of clamping cylinder 51, the output terminal of clamping cylinder 51 tool there are two can in opposite directions or the movable end away from movement,
Connect two jaw plates respectively, to drive two jaw plates opposite or away from movement, thus can realize clamping jaw 52 clamping or
Clamp assembly 5 further includes cushion pad 53, and cushion pad 53 is installed on the contact surface of clamping jaw 52 and work piece.
Cushion pad 53 is used to enhance friction between clamping jaw 52 and work piece, when being fluctuated from cushioning effect, prevent from being added

In other embodiments, cushion pad can also be made of other elastomeric cushion materials, such as PU glue, polyurethane rubber.
Impact when being moved up and down for buffer lift component 2, the switching mechanism that present embodiment provides further include installation
In the buffer limit component 3 on riser 1.Specifically, which includes setting along the moving direction of overturning component 4
Buffer, buffer is arranged at upper end (not shown) and/or the lower end of riser 1, and buffer can be with overturning component 4
It abuts and is compressed.Buffer overturn component 4 move up and down to both ends when from cushioning effect, overturning component 4 is made smoothly to stop
It only moves, prevents that workpiece is subject to larger impact and change in location occurs on clamping jaw 52 and even falls when elevating movement from stopping suddenly
Fall.Buffer ensure that stabilization when workpiece moves up and down.
In present embodiment, the operational process of switching mechanism is as follows：
Clamping cylinder 51 drives clamping jaw 52 to clamp workpiece to be added, and lifting cylinder 21 jacks up upwards, overturns component 4 and clamping group
Part 5 rises under the promotion of lifting cylinder 21.After rising to certain position, component is overturn when lifting cylinder 21 will stop
4 abut the buffer of 1 upper end of riser, and buffer carries out buffer deceleration to the ascending motion for overturning component 4, makes it in lifting cylinder
21 can smoothly stop when stopping.After lifting cylinder 21 stops, the output terminal rotation of tumble cylinder 41 drives clamp assembly 5
Overturning.The output terminal of lifting cylinder 21 is retracted after the completion of workpiece turning movement, and when fallen under close to stop position, buffer supports
Overturning component 4 is connect, buffer carries out buffer deceleration to the descending motion for overturning component 4, by buffer come buffer lift cylinder
21 stop to the impact that workpiece generates suddenly, and so far, workpiece smoothly returns to Working position.
