Description

A clamping device for hardware processing

Technical Field

The utility model belongs to the field of mechanical processing, and in particular relates to a clamping device for hardware processing.

Background Art

When processing hardware parts, the parts need to be positioned and clamped. At this time, a clamp is needed. In the classification of clamps, the device used to prevent the workpiece from displacement or vibration during the processing is called a clamping device.

The patent application with publication number CN204209456U discloses a manual clamping device for columnar workpieces, including: a base plate that serves as a fixed support, and also includes a pressure plate for clamping the columnar workpiece; a V-groove pad for supporting the columnar workpiece is fixedly arranged on the upper middle part of the base plate, a support rod is fixedly arranged on the upper side of the base plate on one side of the V-groove pad, the upper end of the support rod is rotatably connected to one end of the pressure plate through a pin shaft 1, a mounting seat is fixedly arranged on the upper side of the base plate on the other side of the V-groove pad, the mounting seat is rotatably connected to the lower end of the screw rod through a pin shaft 2, and a nut for clamping the pressure plate is arranged on the upper end of the screw.

The above patent simply clamps the cylindrical workpiece through the V-groove pad and the pressure plate. However, when clamping the circular tubular parts inside, the V-groove and the pressure plate may cause the clamping to be unstable due to uneven force on both ends of the pressure plate. Although the V-groove can clamp parts of different diameters, the above application still needs to replace other clamps when clamping parts of different lengths, resulting in low practicality.

In summary, the utility model therefore provides a clamping device for hardware processing to solve the above problems.

By adopting the above technical solution, the tooth plate is meshed with the two gears at the same time and drives them to rotate, so that the gears can synchronously drive the screw to rotate and complete the up and down lifting of the upper fixed seat. At this time, the gears will also slide up and down synchronously with the upper fixed seat to cooperate with the circumferential side of the screw, so that the tooth plate and the two gears always maintain a meshing state, thereby better driving the screw to rotate and realizing the stable lifting of the upper fixed seat.

In summary, the beneficial technical effects of the utility model are:
