The invention discloses a screw-driven type outer circle centering clamping device. The device comprises a rectangular base, a guide rod, a screw, a screw seat, a first clamping arm, a second clamping arm and a propping block; the first clamping arm and the second clamping arm are matched with each other to clamp a component; the screw seat is fixedly arranged at the upper side of one end of the rectangular base; the screw is arranged in the screw seat; the guide rod is glidingly arranged in the middle part of the rectangular base through the guide rod seat; one end of the screw is rotatably connected with one end of the guide rod through the connecting seat, and while the other end of the guider rod is fixedly equipped with a bevel push; the propping block for propping the component is fixedly arranged at the front end of the bevel push head; the first clamping arm and the second clamping arm are respectively rotatably arranged at two sides of a V-shaped groove, on the other end of the rectangular base. The device has the characteristics of being reasonable in design, simple in structure, centering and clamping an outer circle, and being large in force increasing ratio, independent to lock, convenient to operate, long in service life, low in production cost, and convenient to popularize and use.

The invention discloses a threaded self-locking type automatic centering work fixture used for an annular workpiece. The automatic centering work fixture comprises a base plate, a folded bent arm I, a folded bent arm II, a bevel pushing head which matches the folded bent arm I and the folded bent arm II to push the annular workpiece tightly, a driving screw rod used for driving the bevel pushing head to move forward and backward and a screw rod seat which matches the driving screw rod to form a threaded transmission pair. The upper side of one end of the base plate is rotatably provided with the folded bent arm I and the folded bent arm II which are arranged symmetrically, while the upper side of the other end of the base plate is fixedly installed with the screw rod seat. The driving screw rod is installed on the screw rod seat through a threaded hole .The end of the driving screw rod is rotationally connected with the rear end of the bevel pushing head by a connection seat and the fore end of the bevel pushing head is fixedly installed with a pushing block. The fixture provided by the invention has the characteristics of being reasonable in design, simple in structure, capable of excircle centering clamping, high in force increasing ratio, good in self-locking property, convenient to operate and long in service life.

The invention discloses an inclined hole drilling clamp with an adjustable angle. The inclined hole drilling clamp comprises a base, a supporting arm is arranged on the upper side of the base, a sector-shaped guide disc is arranged on the upper side of the supporting arm, the center of the sector-shaped guide disc is in rotating connection with one end of a drilling template, a drilling sleeve is arranged at the other end of the drilling template, an arc guide groove is formed in the middle of the sector-shaped guide disc, and the drilling template is arranged on the sector-shaped guide disc through a fastening bolt matched with the arc guide groove. The inclined hole drilling clamp has the advantages that the inclination angel is adjustable, high universality is achieved, design is reasonable, the structure is simple, the operation is convenient, labor intensity is lowered, production efficiency is improved, dismounting and mounting are convenient, the service life is long, production cost is low, and popularization and use are facilitated.
