Description

TECHNICAL FIELD

[0001] The utility model relates to the field of machining, in particular to a drilling and tapping workpiece clamping device. BACKGROUND

[0002] The hinge of the civil defense door is a key component, and its surface needs to be drilled during the manufacturing process. However, most of the current clamps are special-purpose, which is not versatile enough. When producing different specifications of hinges, the corresponding clamps need to be replaced, which reduces the work efficiency of workers.

[0003] To solve the above problems, the patent with publication number CN218695900U discloses a drilling and tapping machine tool for producing civil defense door hinges, which includes a mounting plate fixedly installed on a drilling and tapping machine. The mounting plate is provided with a rail column disc, and a matching hole block is installed at the center of the rail column disc. A T-shaped ring groove coaxial with the rail column disc is formed in the rail column disc, and a T-shaped arc block is slidably installed in the T-shaped ring groove. The T-shaped arc block is provided with at least four T-shaped arc blocks, and a threaded hole is formed in the T-shaped arc block downward. The threaded hole is threadedly connected with a positioning screw, and the T-shaped arc block is threadedly connected with a screw push rod. The screw push rod is provided with a push angle block at one end close to the axis of the rail column disc. The push angle block includes an L-shaped plate portion, and a cover plate portion is fixedly installed on one side of the L-shaped plate portion. The cover plate portion is located on the upper side after the push angle block is installed. The present application can adapt to different sizes of hinge drilling and tapping by replacing the matching hole block and adjusting the angle of the screw push rod, which reduces the complexity of making and replacing the entire clamp, simplifies the work process, and reduces material consumption.

[0004] For the related technology in the above, the inventors found that the above-mentioned device limits the radial force generated during hinge machining process by using a lead screw. When the lead screw bears a large radial force, it may be deformed, which affects the pressing effect and increases the safety risk in the production process. In addition, the operation of the device is relatively complex, and multiple fixing screws need to be tightened one by one to meet the use requirements, which is complex and reduces the work efficiency.
