Abstract
The utility model discloses a double-clamping mechanism which comprises a rotating air cylinder. The outlet end of the rotating air cylinder is connected with an upper clamping arm, a lower clamping arm is matched with the upper clamping arm, the lower clamping arm is rotationally connected to a supporting arm through a rotating shaft, the supporting arm is fixedly connected with a supporting seat, the supporting seat and a cylinder body of the air cylinder are relatively fixed, a connecting rod is connected between the rear end of the upper clamping arm and the rear end of the lower clamping arm, the two ends of the connecting rod are movably connected with the lower clamping arm and the upper clamping arm respectively through hinge pins, and the workpiece clamping face of the inner side of the front part of the upper clamping arm and the workpiece clamping face of the inner side of the front part of the lower clamping arm are parallel. According to the double-clamping mechanism, the upper clamping arm can rotate along with the action of the air cylinder and drive the lower clamping arm to rotate through the connecting rod, the rotating direction of the upper clamping arm is opposite to that of the lower clamping arm, the purpose of clamping or releasing a workpiece is achieved, and swing supporting is formed on the lower portion of the workpiece. The double-clamping mechanism is simple in overall structure, flexible and reliable in action and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of two-way mechanism that workpiece is clamped.
Background technology
The fixture of holding workpiece at present, some special place needs swinging support, utilizes oscillating cylinder to support, and need to add stops, this mode complex structure, manufacturing cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, reliable in action, is realized swinging support, reduced the dual clamping mechanism of manufacturing cost by interlock mode, overcomes the deficiencies in the prior art.
Dual clamping mechanism of the present utility model, comprise rotary cylinder, the output of rotary cylinder is connected with upper clip arm, is furnished with mutually lower clip arm with upper clip arm, lower clip arm is rotatably connected on support arm by turning cylinder, support arm is fixedly connected with supporting seat, supporting seat is relative fixing with the cylinder body of cylinder, between upper clip arm and the rear end of lower clip arm, be connected with connecting rod, the two ends of connecting rod are flexibly connected with lower clip arm and upper clip arm by bearing pin respectively, and the anterior inner side piece-holder face of described upper clip arm and lower clip arm is parallel to each other.
Dual clamping mechanism of the present utility model, when cylinder action, upper clip arm can rotate thereupon, drives lower clip arm to rotate by connecting rod simultaneously, the direction of rotation of upper clip arm and lower clip arm, the object that realizes clamping or unclamp workpiece, makes the bottom of workpiece form swinging support.Overall structure is simple, and flexible movements are reliable, low cost of manufacture.
Brief description of the drawings
Fig. 1 is the structural representation of piece-holder state in the utility model detailed description of the invention;
Fig. 2 is the structural representation of workpiece releasing orientation in the utility model detailed description of the invention.
Detailed description of the invention
As shown in Figure 1, 2: 1 is rotary cylinder, and the output 12 of rotary cylinder 1 is connected with upper clip arm 2 by connector 3, when output rotates, can drive upper clip arm 2 to rotate.Is furnished with mutually lower clip arm 4 with upper clip arm 2.Lower clip arm 4 is rotatably connected on support arm 9 by turning cylinder 8, and support arm 9 is bolted to connection with supporting seat 11, and supporting seat 11 is relative fixing with the cylinder body of cylinder 1.Between upper clip arm 2 and the rear end of lower clip arm 4, be connected with connecting rod 7, the two ends of connecting rod 7 are flexibly connected with lower clip arm 4 and upper clip arm 2 by the first bearing pin 14 and the second bearing pin 10 respectively.The anterior inner side piece-holder face of upper clip arm 2 and lower clip arm 4 is parallel to each other.On upper clip arm 2, be fixedly connected with upper dead flake 5, on lower clip arm 4, be fixedly connected with lower stops 6, between lower stops 6 and lower clip arm 4, establish and adjust pad 13, when upper clip arm 2 and lower clip arm 4 contact with lower stops 6 by upper dead flake 5 when rotating carry out spacing.
