Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.

Example (b): a steel plate processing clamp, as shown in figure 1, comprises a fixed seat 1, wherein the fixed seat 1 is fixed on a movable component which can move on the edge of a machine tool. Fixing base 1's front (the utility model discloses "front" is the left surface in the schematic diagram) bottom is L shape, forms a steel sheet stretching groove 2 of inwards seting up, and the bottom surface that the steel sheet stretched into groove 2 is a plane and a wedge face from inside to outside in proper order, and the steel sheet of being convenient for stretches into. The steel sheet stretches into the top of groove 2 and is equipped with a arm lock 3, and arm lock 3 articulates in the positive position of being close to fixing base 1, and its free end inwards extends to the steel sheet and stretches into the plane top that the groove has for can cooperate the steel sheet to stretch into the bottom surface of groove 2 to grasp the steel sheet when arm lock 3 rotates. In this embodiment, one end fixedly connected with connecting rod 4 that free end was kept away from to arm lock 3, and the relative top of fixing base 1 is equipped with a cylinder 5, and cylinder 5 rotationally sets up, and the output of cylinder 5 is articulated with the one end that arm lock was kept away from to connecting rod 4.

In the embodiment, the connecting rod 4 and the clamping arm 3 are integrally formed or welded, the connecting rod 4 and the clamping arm 3 are in a certain crossed bottom to form a lever structure, after the edge of the steel plate extends into the steel plate extending groove 2, the connecting rod 4 is driven to rotate in the retraction process of the air cylinder 5, the clamping arm 3 is pressed downwards so as to clamp the steel plate by matching with the bottom surface of the steel plate extending groove 2, and then the steel plate can be driven to move by moving the moving part so as to process the steel plate; when the cylinder 5 is pushed out, the clamping arm 3 is driven to rotate upwards, and the steel plate is loosened. Two sides of the cylinder 5 are hinged to the top of the fixed seat 1 through pin shafts, and are matched with the hinge connection of the cylinder output rod and the connecting rod 4 to adjust the angle in a self-adaptive mode.

In this embodiment, the free end of arm lock 3 is equipped with a pressure head 6 of downward vertical extension, supports the pressure to the steel sheet through pressure head 6.

In this embodiment, the back side of the fixed seat 1 is provided with a dovetail groove 7 with adjustable width, which is used for matching with a dovetail guide bar on the moving component. Specifically, one side of the dovetail groove 7 is formed by a movable block 8 which can move up and down, and the other side is fixedly arranged on the fixed seat 1, and the width of the dovetail groove 7 can be changed by moving up and down the movable block 8. Screw thread matching has a fastening bolt 9 on the fixing base, and fastening bolt 9's bottom and movable block 8 rotationally are connected, can drive the movable block through rotating fastening bolt 9 and reciprocate to can match dovetail and forked tail conducting strip fixedly. In addition, a bottom plate is welded on the bottom surface of the fixed seat 1, and a certain supporting effect is achieved.

Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above-described embodiments, and many modifications are possible. All changes and modifications that may be made by the technical spirit of the present invention to the above embodiments by simple modification are considered to fall within the scope of the present invention.
