Abstract
The utility model relates to a kind of self-centering hydraulic clamping mechanisms.Including cylinder body, rack piston, fixture, gear, platen, its structure is, the piston of rack gear is had there are two disposing in the intracorporal left and right of a cylinder, is provided with a gear between two rack pistons, this gear is meshed with the rack gear of two piston portions simultaneously.Left and right fixture is bound up on respectively on two rack pistons in left and right.Using this sleeve gear engaging structure, guarantee the mobile synchronous realization self-centering clamping of fixture of two pistons.The utility model has the advantages that structurally reasonable, adjustment is easy for installation, and self contering structure is stablized.Specifically for fork with tongue batch machining, the adjustment time that is loaded of feeling relieved every time is reduced, a kind of reasonable solution is provided.
Description
Technical field
The utility model is to belong to heavy machine tool industry, is particularly suitable for numerical control gantry rail milling machine tool technology and pattern assembly fixture
Technical field is a kind of self-centering hydraulic clamping mechanism.
Background technique
With the development of numerical control gantry rail lathe and various rail technologies.Lathe from processing No. 50 and No. 60 basic steels
Rail development need to process No. 18 forks with tongue, 42 forks with tongue.And this tongue is on lathe when processing, technique requires fork with tongue
Center is consistent with the center of platen.Since former tooling fixture is complicated and is to manually adjust, the large labor intensity time is long,
Human factor, which will affect, is processed fork with the quality of tongue.
Summary of the invention
The purpose of this utility model is aiming at the shortcomings in the prior art, to propose that one kind can guarantee that fork is being loaded with tongue
When, be not in that the adjustment time that is loaded is long, can guarantee after primary adjustment repeat to be loaded feel relieved it is accurate.By being arranged on lathe
Multiple self-centering hydraulic clamping mechanisms can guarantee fork, and be loaded every time with tongue can self centering Hydraulic Clamping Mechanism.
The utility model self-centering hydraulic clamping mechanism, including cylinder body, rack piston, fixture, gear, platen,
Its structure is, in the intracorporal left and right placement of a cylinder there are two the piston for having rack gear, is provided with one between two rack pistons
A gear, this gear are meshed with the rack gear of two piston portions simultaneously.It is living that left and right fixture is bound up on the rack gear of left and right two respectively
Beyond the Great Wall.Using this sleeve gear engaging structure, guarantee the mobile synchronous realization self-centering clamping of fixture of two pistons.
The utility model has the advantages that structurally reasonable, adjustment is easy for installation, and self contering structure is stablized.Specifically for fork with point
Rail batch machining reduces the adjustment time that is loaded of feeling relieved every time, provides a kind of reasonable solution
Detailed description of the invention
Attached drawing 1：Self-centering hydraulic clamping mechanism makes implementation diagram.
Specific embodiment
1 self-centering hydraulic clamping mechanism of attached drawing makes implementation diagram.Including cylinder body 1, left rack piston 2, right rack piston
3, its composition of left fixture 4, right fixture 5, gear 6, platen 7.Cylinder body 1 is fixed on workbench 7, and left rack gear is living
Plug 2, right rack piston 3 are installed in cylinder body 1, gear 6 be installed in cylinder body 1 and simultaneously with left rack piston 2, right rack piston
3 engagements, left fixture 4 is installed on fixation in left rack piston 2, right fixture 5 is installed in right rack piston 3 and fixes.When there is side
Logical oil will push piston driving fixture mobile, and due to having a pinion gear among the piston of left and right, the card of the other side is driven by gear
Has opposite synchronizing moving, to realize self-centering clamping function.
