It is vertical hold down assembly, the level that in the vertical direction and workpiece placement rack link and moved horizontally holds down assembly, drives water
The vertically moving vertical actuator of case, the telescopic support for being fixed on water tank and being located at workpiece placement rack bottom,
The first connector that the telescopic support includes be connected with water tank, the second connector with the socket of the first connector, it is connected the
The dynamic clamping head and quiet clamping head of a connection piece and the second connector, first connector and the second connector vertically occur relatively
Move and dynamic clamping head and quiet clamping head is compressed after the first connector is connected with second with regard to part generation relative motion.
Gas braking joint is in hollow L-shaped, and its two ends respectively sets opening, and the axis of two openings is vertical.When work,
Gas braking joint is placed on workpiece placement rack, one of them opening down abutting workpiece placement rack, level of gas braking joint
Hold down assembly and first close another opening of gas braking joint；Vertical actuator drives water tank to move upwards afterwards, when flexible branch
When support member abuts water tank bottom, dynamic clamping head and quiet clamping head is by continued compression；When telescopic support is enough to overcome workpiece placement rack and level
During the gravity held down assembly, dynamic clamping head and quiet clamping head stops being compressed, and workpiece placement rack drives upward motion by telescopic support；Work as work
After gas braking joint abutting on part placement rack holds down assembly vertically, with the motion further up of water tank, dynamic clamping head and quiet clamping head
The water being further compressed in water tank did not had gas braking joint, now air intake assembly air inlet, by observing in water whether have gas
The air-tightness of bubble detection gas braking joint, without bubble, illustrates that gas braking joint air-tightness is preferable；There is bubble, illustrate that gas is braked
Joint there may be greatly problem very much.
Further, the auxiliary elastic member positioned at workpiece placement rack bottom is also associated with the water tank.
So reduce the amount that dynamic clamping head and quiet clamping head is compressed when overcoming workpiece placement rack and level compression group gravity.
Further, the workpiece placement rack includes some station grooves, set in each station groove an elastic sealing gasket with
And the valve passed in own elasticity sealing gasket, the air intake assembly connects air pump gas outlet and valve respectively including air pump, two ends
Tracheae.
Further, it is described it is vertical hold down assembly including be fixedly connected with base connecting rod, be fixed on connecting rod bottom
Connecting plate, be fixed on the vertical pressure head of connecting plate bottom.
Gas braking joint is compressed by vertical pressure head.
Further, an installing plate is fixed in the workpiece placement rack bottom, and the level holds down assembly including being fixed on one
Horizontally disposed motion bar, one, which fix on a mounting board and is enclosed on the stop collar on motion bar, one end, is hinged L on a mounting board
The connection sheet that shape connecting rod, two ends are hinged with the middle part of L-shaped connecting rod and motion bar one end respectively, the other end of L-shaped connecting rod fixes one
Handle.
By rotating L-shaped connecting rod, when the middle part of L-shaped connecting rod is located at the pin joint and motion bar of L-shaped connecting rod and installing plate
Between, while when three pin joints are located on same level straight line, motion bar abuts an opening of sealing gas braking joint.
Further, the motion bar fixes an elastic packing post away from L-shaped connecting rod one end.
Lift the sealability to gas braking joint opening.
Further, the water tank bottom is fixed with lead, and the lead is through base and with the relative bottom of water tank
Seat motion.
Water tank stable movement.
Further, the vertical actuator is cylinder or hydraulic cylinder.
Further, the dynamic clamping head and quiet clamping head is compression spring.
Further, the auxiliary elastic member is rubber column.
In summary, the invention has the advantages that：Everything is only completed by a cylinder, structure is simpler
It is single.
