Description

Technical Field

[0001] The utility model belongs to the technical field of drilling equipment and relates to a clamp head seat drilling mechanism. Background Art

[0002] Sampling forceps are medical devices widely used in clinical practice. When in use, the sampling forceps are inserted into the human body through the clamp channel of the endoscope. The sampling forceps are opened during use to clamp tissue samples for subsequent pathological research based on the samples. The forceps head is an important part of the sampling forceps and is used to install and fix the clamps for clamping tissue samples. During the processing of the forceps head, the forceps head needs to be drilled. However, the drilling equipment in the existing technology uses a translational slide rail structure to move the tooling fixture holding the forceps head in and out. The loading and unloading of the forceps head cannot be carried out synchronously, resulting in reduced drilling efficiency of the forceps head.

The four clamp head seat installation stations are set up to separate the loading, drilling and unloading of the clamp head seat, so that the loading, drilling and unloading can be carried out synchronously to improve the drilling efficiency of the clamp head seat. When the clamp head seat moves to the side close to the top seat 3, the lifting mechanism can drive the drilling mechanism to descend for drilling.

[0025] Specifically, the drilling mechanism 5 includes a lifting base 8 on which a drill bit 9 driven by a cylinder is installed. The lifting base 8 is located directly above the clamp head mounting station on the side close to the top base 3. The cylinder can drive the drill bit to work and thus enable drilling.

The bottoms of the clamping plates 14 extend to the underside of the rotating disk 6 and are connected to a clamping plate driver fixed to the bottom of the rotating disk 6. The two clamping plate drivers operate synchronously to drive the two clamping plates toward each other, thereby clamping the clamp head.

[0032] Specifically, the lifting and lowering pressure plate assembly includes a curved pressure plate 16 arranged inside the clamp head seat installation station, and a lifting cylinder connected to the curved pressure plate 16 is fixedly connected to the bottom of the rotating disk 6. The lifting cylinder can drive the curved pressure plate down so as to limit the clamp head seat.
