[0015] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0016] See also Figures 1 to 4The utility model provides a clamping mechanism for an insert nut, which includes a T-shaped mounting seat 1, and mounting holes are symmetrically opened on the front and rear sides of the upper end of the mounting seat. A support plate is vertically arranged on the upper end of the mounting seat 1, and a fixing block 2 is arranged on the right end of the supporting plate. A longitudinal slider 4 driven by a longitudinal cylinder 5 is slidably arranged on the fixing block 2 for forward and backward movement. A sliding member 6 driven by a lifting cylinder 7 is slidably arranged on the right side of the longitudinal slider 4 for upward and downward movement. Two clamping claw cylinders 8 distributed on the left and right for clamping the insert nuts are arranged downward at the front end of the sliding member 6, and the two insert nuts are clamped at the same time. The clamping claw cylinders realize the clamping or grasping of the workpiece through air pressure control, which replaces the grasping work of people, can not only improve the production efficiency, but also have high efficiency, stability, high flexibility and precision. The insert nut to be processed or tested can be clamped by the clamping mechanism, so as to load and unload the insert nut. The longitudinal slide is driven by the longitudinal cylinder to move the sliding part and the lifting cylinder forward and backward. The lifting cylinder drives the sliding part to move the two clamping cylinders up and down, so that the clamping cylinders approach and clamp the insert nut, and then move the insert nut to another place to loosen it, so as to complete automatic loading or unloading.

[0017] The fixed block 2 is concave, and two first slide rails 3 are longitudinally arranged at the groove of the fixed block 2 to accommodate the longitudinal slider 4 and are distributed up and down, and the longitudinal cylinder 5 connected to the longitudinal slider 4 is arranged forward on the fixed block 2. The concave fixed block can be provided with the longitudinal cylinder and the first slide rail, and the longitudinal slider can slide forward and backward with the sliding member through the first slide rail.

[0018] See also Figure 1 , Figure 3 The sliding member 6 is composed of a lifting slider 6.1, a mounting plate 6.2, and a connecting block 6.3. The lifting slider 6.1 and the mounting plate 6.2 are connected by an L-shaped connecting block 6.3. A second slide rail for sliding the lifting slider 6.1 is vertically arranged at the right end of the longitudinal slider 4. A stabilizing block is horizontally arranged at the top of the longitudinal slider 4. The lifting cylinder 7 connected to the lifting slider 6.1 is downwardly arranged at the top of the stabilizing block. The lifting slider and the mounting plate are connected by the connecting block, and the sliding member and the clamping claw cylinder are slid up and down by the second slide rail.

[0019] A cylinder is disposed transversely on the right side of the upper end of the lifting slider 6.1, and a circular hole for the cylinder to pass through is provided at the lower end of the piston rod of the lifting cylinder 7. The cylinder and circular hole arrangement can avoid hard connection, and the lifting cylinder can also drive the lifting slider while reducing the thickness of the lifting slider.

[0020] A support column 10 is vertically arranged at the upper end of the mounting base 1, and a blanking plate 9 is obliquely arranged on the support column 10 and is located below the clamping cylinder 8. The blanking plate is suitable for blanking the insert nut. When the insert nut is loaded, the support column and the blanking plate can be removed, and the insert nut clamped by the clamping cylinder moves to the top of the blanking plate. The insert nut released by the clamping cylinder falls to the blanking plate and slides down for collection.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
