Description
Technical field
The present invention relates to hydraulically operated fixture field, more particularly, to a kind of more clamping hydraulically operated fixtures.
Background technology
Hydraulically operated fixture can ensure part in defined position on secured clamping, existing hydraulically operated fixture is in production process
In the limitation that faces have the following：1st, time processing is only capable of clamping one or several parts, and processing efficiency is low；2nd, most folders
Have for can enable the hold assembly of fixture securely holding parts the external structure of hold assembly would generally be done and part
It fits like a glove, lacks fault-tolerant space, cause fixture hold assembly loss in part processing serious；3rd, position limiting structure design does not conform to
Reason.It is to ensure an important factor for fixture can be accurately positioned, existing fixture in the position limiting structure that each orientation is provided on fixture
Position limiting structure, which seldom causes to position inaccurate or position limiting structure, much so that clamp movement is dumb；4th, hydraulic oil
Connection mode is unreasonable between cylinder and piston, and the piston motion in processing is caused to be obstructed.
Invention content
The purpose of the present invention is to provide a kind of more clamping hydraulically operated fixtures, it is intended to solve the above problems.
To achieve these goals, the technical scheme is that a kind of more clamping hydraulically operated fixtures are designed, including fixture master
Body, double-workbench；The double-workbench includes disc base, baffle, support base；The disc base is rotary type structure；
Disc base is divided into two regions by the central part that the baffle is located at disc base；The support base is separately positioned on disk
In two regions that pedestal is gone out by barrier partitions；Several jig main bodies placed side by side on each support base；The fixture
Hydraulic cylinder is equipped among main body, if hydraulic cylinder both sides are uniformly distributed dry slide；Being equipped in the slideway can be in the slideway
The piston of slip, and two pistons in two side slideway of hydraulic cylinder same position are connected by a tension spring；The liquid
Compressing cylinder is equipped with oil sealing with piston interface；The piston inner wall is equipped with slot, and the clamp spring for fixed spring is equipped in the slot；
The piston is equipped with the limiting chamfering of limitation piston motion maximum distance；The piston nose connection sliding block；On the sliding block
Surface both sides are equipped with invagination slot；The sliding block is assumed a " convex " shape with piston interface；The sliding block and part to be processed phase-contact surface
Shape be the shape identical with piece surface shape；The jig main body is equipped with several parts grooves；The sliding block is in part
It is slided in slot；The position that parts groove upper surface both sides are located at the invagination slot of sliding block is equipped with banking stop；The banking stop is in cunning
Part edge in the invagination slot of block is arc-shaped；Anti-slip tank is equipped on the inside of the parts groove；The slip front surface is equipped with anti-
Sliding slot.
Fault-tolerant gap is equipped on the inside of the parts groove, the fault-tolerant gap between part to be processed is 0 ~ 0.5mm.
The invagination slot size is more than the size of part of the banking stop in invagination slot.
Entirety of the invention uses process：Part is put into parts groove one by one first, a lateral areas of the double-workbench that takes the lead in being booked
Then domain rotates double-workbench so that the parts groove for filling part is made to be located at Working position, part is machined in the side
While double-workbench opposite side parts groove in can be carried out at the same time being put into and clamping for part, the part of position to be processed adds
After work, double-workbench can be rotated, the part just clamped is allowed to go to Working position and is processed, and it is processed complete
This complete side part can complete the process disassembled from fixture simultaneously.
The use process of present clip main body：Part is put into parts groove, to being passed through oil pressure in hydraulic cylinder, oil pressure pushes away
Piston moves out, and piston driving sliding block moves in parts groove, ram extrusion fix generation processing part, parts groove and
The anti-slip tank of shoe surface prevents from being subjected to displacement in part process.In addition, the invagination slot mating parts slot both sides on sliding block
Banking stop can realize sliding block only in the movement of parts groove same level, without upper and lower displacement.Banking stop is in cunning
The size of part that part edge in the invagination slot of block is arc-shaped and invagination slot size is more than banking stop in invagination slot, this
Structure causes piston when sliding block is pushed, and slight shift can occur in the lateral direction for sliding block, in mating parts slot
Fault-tolerant gap, impact stress reduces during can causing sliding block clamping parts to be processed, and the longevity is used so as to fulfill sliding block
The extension of life.Being equipped with oil sealing in piston exterior can effectively prevent oil in oil cylinder excessive.Due to hydraulic cylinder same position both sides
Piston controlled using same tension spring, thus clamp spring is set to fix tension spring in piston, while the limiting on piston is coordinated to fall
The scope of activities of angle control tension spring is between hydraulic cylinder inner wall and oil cylinder center line.
The advantages of the present invention are：A kind of double-workbench design of more clamping hydraulically operated fixtures of the present invention solves
The processing of part is with dismounting synchronous to be carried out, and effectively improves working efficiency；The multiple limiting of sliding block and parts groove, which designs, to be caused
Fixture can be completed to be accurately positioned, and the fault-tolerant design of sliding block and parts groove causes impact stress when sliding block and part contact with each other
Reduce, damage of the anti-limited slip block to part, reduce the loss of sliding block itself.
