The clamp comprises a round base, wherein one end face of the round base is connected with a lathe spindle; two groups of symmetrical clamping mechanisms are arranged on the other end face of the round base; one ends of first positioning pins are in threaded connection with the round base, and the other end of the first positioning pins are in plug-in connection with pin holes in one end parts of the brake shoes; one ends of second positioning pins are in threaded connection with the round base, and the other end of the second positioning pins are in threaded connection with flexible chucks which are movably connected to pin holes in the other end parts of the brake shoes; one ends of all auxiliary support nails are in threaded connection with the round base, and the other ends of all the auxiliary support nails are propped against and connected with one side faces of the inner ribbed plates of the brake shoes; one end of a screw is in threaded connection with the center of the round base, and the other end of the screw is in plug-in connection with a pressure plate for pressing the two brake shoes on the two groups of clamping mechanisms; a tightening nut is arranged at the end part, outside the pressure plate, of the screw. The clamp is reasonable in structure design, can machine two brake shoes at a time, is high in clamping and unclamping speeds, increases the machining efficiency and reduces the labor strength of workers.
Description
Technical field:
The utility model relates to a kind of brake shoes turning clamp.
Background technology:
Brake shoes is the accessory stopped of drum, refers to be subject to the actuating quantity of brake cam or push rod and to be pushed to outer expansion compacting brake and to heave the accessory of braking action, and its shape is as semilune.Existing brake shoes turning clamp at every turn can only brake shoes of clamping, and handling speed is slow, and working (machining) efficiency is low, and labor strength is large.
Utility model content:
The utility model provides a kind of brake shoes turning clamp, and its reasonable in design can process two brake shoes, and handling speed is fast, has improved working (machining) efficiency at every turn, has reduced workman's labour intensity, has solved problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is: it comprises cup dolly, one end face of cup dolly is connected with lathe spindle, other end is provided with two groups of symmetrically arranged clamping mechanisms, every assembling clamp mechanism comprises the first alignment pin that circumferentially arranges and match with brake shoes along cup dolly end face, the second alignment pin and several supplemental support nail, one end of the first alignment pin is threaded with cup dolly, one end pin-and-hole of the other end and brake shoes is pegged graft, one end of the second alignment pin is threaded with cup dolly, the other end collet being flexibly connected with the other end pin-and-hole of brake shoes that is threaded, one end of each supplemental support nail is threaded with cup dolly, the inner reinforced plate side of the other end and brake shoes connects, one end of screw rod is threaded with cup dolly center, and the pressing plate of two brake shoes on two assembling clamp mechanisms is pushed down in other end grafting one, is provided with a fastening nut in the screw rod end in pressing plate outside.
On the screw rod between pressing plate and fastening nut, be provided with U-shaped backing plate.
Described supplemental support nail is two.
Described supplemental support nail is sphere with the end that the inner reinforced plate side of brake shoes connects.
The utility model adopts such scheme, and reasonable in design can be processed two brake shoes at every turn, has improved working (machining) efficiency; On the screw rod between pressing plate and fastening nut, be provided with U-shaped backing plate, the number of turns that can reduce each handling brake shoes time, fastening nut rotates, the handling speed of raising brake shoes, has reduced workman's labour intensity.
