Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail with reference to examples and drawings.
As shown in fig. 1, a milling fixture structure for double-station eccentric wheel clamping comprises: the device comprises a base 1, a transmission piece 2, a left swing rod 3, a connecting plate 4, a movable jaw 5, a jacking column 6, a right swing rod 8 and an eccentric wheel 9;
the base 1 is provided with a fixed jaw, and round holes are respectively formed in the middle position, the front position and the rear position of the base; a round hole which is penetrated left and right is formed in the middle of the middle lower part, the front part and the rear part of the base 1; the transmission part 2 is arranged in the round hole and can move left and right; the connecting plate 4 is provided with two connecting plates which are respectively fixed at the front and the rear of the middle of the base; the left swing rod 3 and the right swing rod 8 are respectively connected to the left side and the right side of the connecting plate 4 and can swing around the axle center; the movable jaws 5 comprise two movable jaws 5, a straight notch is formed in the middle of each movable jaw 5, a cylindrical pin is clamped in the middle of each straight notch, and two ends of each cylindrical pin are respectively connected to the upper ends of the left swing rod 3 and the right swing rod 8; the two jacking posts 6 are respectively arranged in left and right round holes at the middle and upper part of the base, and an elastomer is arranged between the jacking posts and the bottoms of the round holes; the eccentric wheel 9 is connected to the lower end of the right swing rod and can rotate around the axle center. The elastic body may be a spring, but is not limited thereto.
The clamp also comprises a handle 7 and a locking screw 10; the handle 7 is fixed on one side of the eccentric wheel 9, and the eccentric wheel 9 is driven to rotate by pulling the handle 7; the locking screw 10 is fixed in front of the eccentric 9.
The movable jaw 5 is arranged above the connecting plate 4, the connecting plate plays a role in guiding the movement form of the movable jaw, and the movable jaw translates on the upper surface of the connecting plate.
A straight notch is arranged between the left swing rod and the right swing rod, a bolt is arranged in the notch, the bolt is connected with a round hole of the movable jaw through the straight notch, and the connection mode and the upper surface of the connecting plate jointly play a guiding role on the movable jaw. The bolt is in fastening connection with the movable jaw; the vertical circle center distance of the straight slot opening of the left swing rod and the right swing rod is 3mm, and the diameter of the straight slot opening is larger than that of the bolt, so that the bolt can relatively slide in a certain range in the slot opening, and simultaneously can relatively swing rod to perform rotary motion and superposition of the two actions of the relative sliding and the rotary motion, so that when the swing rod swings, the bolt and the movable jaw perform left-right translational motion.
The left swing rod and the right swing rod realize the swing transmission mode that: the handle drives the eccentric wheel to rotate, the eccentric wheel pushes the transmission piece to move leftwards, and the transmission piece pushes the swing rod to swing.
As shown in fig. 2a, 2b and 2c, when the handle is pressed down, the eccentric wheel is driven to rotate, the eccentric wheel pushes the transmission member to move leftwards, and the transmission member pushes the swing rod to swing. The bolt connected to the swing rod pushes the movable jaw to translate inwards, so that two workpieces are clamped simultaneously.
As shown in fig. 3a, 3b and 3c, when the handle is lifted, the movable jaw is reset under the action of the spring and the top post.
The transmission piece adopts 45# materials, and the eccentric wheel adopts T8A materials, so that good deformation resistance and wear resistance are ensured.
Although the embodiments of the present invention are described above, the embodiments are only used for facilitating understanding of the present invention, and are not intended to limit the present invention. Any person skilled in the art can make any modification and variation in form and detail without departing from the spirit and scope of the present disclosure, but the scope of the present disclosure is still subject to the scope of the appended claims.
