Description
Technical field
The invention belongs to a kind of chuck apparatus technical field more particularly to a kind of machine components clamping devices.
Background technology
Fixture refers to that machine-building is used for fixing processing object in the process, is allowed to occupy correct position, to receive construction
Or the device of detection, also known as fixture.In a broad sense, any process in technical process is used for rapidly, easily and safely
The device for installing workpiece, all can be described as fixture.
Traditional small part, such as：Screw, bolt, nut or bolt generally require to pass through when carrying out spray painting processing
Fixture grips, and carries out subsequent painting process later.However, since volume of part is smaller, and different types of part
Size it is different, be mostly currently that a kind of part corresponds to a type of fixture, staff in processing different parts,
Different types of fixture can be frequently replaced, causes workload huge, and common fixture tastes needs when debugging opening
The angle or the amount of feeding of each gripper are adjusted successively, and process is very slow, so the different fixtures of ordinary debugging can lead to zero
The process velocity of part slows down, and influences the processing progress of entire part, causes the production and processing progress of part slow, inefficiency.
Invention content
In order to solve one or more drawbacks described above in the prior art, technical problem to be solved by the invention is to provide
A kind of machine components clamping device, the part of adaptation and a variety of different sizes, avoids frequently replacing fixture, ensures part

It grabs and is fixedly connected, the position of pedestal and gripper is fixed relative to turntable, therefore is rotated in turntable and drive restraint zone
When movement, when turntable turns to certain position, restraint zone will be tightened, and turntable is rotated further, and restraint zone will be to gripper
Constitute traction, force gripper deflect to pedestal along its hinge joint, and then among gripper workpiece or part press from both sides
Tightly.During this, it is only necessary to rotate forward or reversion turntable can be uniformly controlled the tightness of restraint zone, and then quickly adjust
Save the opening degree of gripper, in order to be able to quickly meet the replacement or clamping of part.The opening of the gripper of the present apparatus simultaneously
It is sized to adjust, the part of different size or model can be adapted to.Gripper includes interconnecting piece and clamping part, interconnecting piece with
Pedestal is hinged；One end of clamping part is fixedly connected with the top of interconnecting piece, and the other end is tilted along fixed point to pedestal side, clamping
The angle in portion and side of the interconnecting piece towards pedestal is less than 90 degree, and when Clamp blocks, clamping part can be given gripper always
Clamped part applies the active force towards pedestal so that part can be firmly bonded with turntable, and part is avoided to be added
Occur falling off or slide during work, influences processing quality.
Further, the driving mechanism includes the worm screw being located on pedestal, the surface of the shaft be equipped with a circle with
The helical gear of worm screw cooperation, staff rotate forward worm screw, and worm screw rotation drives the helical gear rotation being engaged with, and then band
Turn shaft rotation is dynamic, so as to drive turntable to rotate, and then the gripper Clamp blocks for being, similarly, staff rotates backward snail
Bar can unclamp part.
Further, the circle that gripper is formed is overlapped with the center of circle of turntable so that whole equipment transmission is more stablized.
Further, the quantity of through-hole is equal with the quantity of the gripper.
Further, shaft is equipped with locating slot, and the pedestal, which is equipped with, may pass through pedestal and coordinate with locating slot
Positioning pin after part is fixed, can avoid loosening by positioning pin insertion to limit rotary shaft.
Further, restraint zone be polyurethane material make strip restraint zone, polyurethane have good toughness and
Intensity is hardly damaged.
Further, one end of clamping part and feature contacts is equipped with skid resistant course, and the anti-skidding layer surface is arc, and anti-skidding
The surface of layer is evenly distributed with anti-skid bulge, increases friction, avoids loosening.
The present invention at least has the advantages that：The present invention is adapted to the part with a variety of different sizes, avoids frequency
Numerous replacement fixture ensures the process velocity of part, and can adjust whole grippers simultaneously, saves the time.
