Abstract
The utility model discloses an adjustable sluice valve fastening device, and belongs to mechanical workpiece fixing devices and in particular relates to a device for fixing a circular plane workpiece. The adjustable sluice valve fastening device comprises a panel for carrying objects and pressing jaws. The adjustable sluice valve fastening device is characterized in that the panel for carrying objects is provided with the three pressing jaws which are uniformly distributed in a radial manner. The panel below the pressing jaws is provided with three guide holes which are uniformly distributed in a radial manner. A fastening oil cylinder corresponding to the pressing jaws is installed on the bottom face of the panel. Pull rods of the fastening oil cylinder are fixedly arranged on the pressing jaws. Fastening oil cylinder guide rails are respectively installed on both sides of the fastening oil cylinder, one side of the fastening oil cylinder, facing the center of a work panel, is provided with two oil cylinders respectively connected with intersecting straight pull rods. The other oil cylinder is connected with a pull rod which pulls the oil cylinder. The other end of the straight pull rod is respectively connected with the external ends of the two V-shaped pull rods with connected internal ends. Connecting shafts at the internal ends of the two V-shaped pull rods are connected with external side of the oil cylinder connected with the pull rod which pulls the oil cylinder. The adjustable sluice valve fastening device has the advantages that the efficiency is high and the centre of the circle can be positioned accurately.
Description
Technical field
The utility model belongs to the mechanical workpieces fixture, especially for the fixing device of circular flat workpiece.
Background technology
The time gate valve need to be fixed on the panel of testing equipment gate valve being carried out to the air-tightness experiment, mostly existing fastening method is that independently paw is fixing respectively, this method one be efficiency low, the 2nd, be not easy to aim at the center of circle.
The utility model content
In order to overcome existing independent paw, fixed efficiency is low respectively, be not easy to aim at the deficiency in the center of circle, the utility model provides a kind of adjustable gate valve fastener, and this adjustable gate valve fastener has not only improved fastening speed, and can be able to automatically adjust and aim at the center of circle.
The utility model solves the technical scheme that its technical problem adopts: a kind of adjustable gate valve fastener, comprise the panel that loading is used, paw, it is characterized in that: be equipped with on the panel that loading is used and be radial equally distributed three paws, panel under paw is provided with and is radial three pilot holes that are uniformly distributed, the fastening oil cylinder corresponding with paw is equipped with in the panel bottom surface, fastening cylinder putter is fixed on paw, fastening oil cylinder guide rail is equipped with respectively in fastening oil cylinder both sides, fastening oil cylinder has two oil cylinders to be connected with cross one another straight push rod respectively towards working panel center one side, another oil cylinder is connected with the push rod that promotes oil cylinder, the other end of straight push rod is connected with the outer end of interconnective two the V-type push rods in the inner respectively, the oil cylinder outside that the inner connecting axle of two V-type push rods is connected with push rod with promoting oil cylinder is connected.
Described straight push rod is equipped with straight push rod guide pad outward, and two arm lengths of described V-type push rod are identical, and be equipped with and the V-type push rod fixed axis be fixed on panel on its summit.
Described promotion oil cylinder is fixed on panel by promoting cylinder bracket.
Described straight push rod front end is equipped with straight push rod pushing block, and V-type push rod pushing block is equipped with at described V-type push rod connecting shaft place, and described promotion cylinder putter front end is equipped with and promotes the cylinder putter pushing block.
The using method of adjustable gate valve fastener, it is characterized in that: start and promote oil cylinder, promote cylinder putter and promote the outer end that coupled fastening oil cylinder drive paw moves to pilot hole, under the effect of the V-type push rod mutually linked and straight push rod, two other fastening oil cylinder Timing Belt dynamic pressure pawl moves to the outer end of pilot hole, this is that the workpiece of needs clamping is put on panel, reverse starting promotes three paws of oil cylinder drive and moves to the top of the workpiece that needs clamping to face plate center, then starting fastening oil cylinder paw will need being fixed on panel of workpiece of clamping, for relevant device, it is processed, completion of processing starts aforesaid reverse program workpiece is taken off.
The beneficial effects of the utility model are both to have improved operating efficiency, alleviated labour intensity owing to having used hydraulic jack to drive the fastening work that synchronization-moving three paws carry out round piece, the guaranteed location in the center of circle.
