Description

Machine tool chuck positioning device Technical Field The utility model relates to the technical field of machine tool chuck positioning, in particular to a machine tool chuck positioning device. Background In the grinding and polishing process, the feeding link of grinding, polishing agent or grinding agent is indispensable, the chuck plays an extremely critical role, the chuck serves as a precise conveying and controlling part, has a precise flow regulating function, can precisely control the feeding amount of the grinding, polishing agent or grinding agent according to the requirements of a processing technology in different processing stages, needs a large processing agent dosage in order to rapidly remove materials in a rough processing stage or needs a micro and stable feeding in order to realize high-precision surface treatment in a finish processing stage, can be precisely adapted, and meanwhile, the conveying mode of the chuck is quite stable, can ensure that the processing agent is uniformly distributed in the contact area of a workpiece and a grinding tool, and avoids surface quality problems such as scratches, inconsistent roughness and the like caused by uneven distribution of the processing agent. The utility model discloses a positioner for lathe chuck of "CN 219852182U", including the lathe chuck, the fixed disk has been taken to one side of lathe chuck, a plurality of screw holes have all been seted up on fixed disk and the lathe chuck, every two threaded hole threaded connection have same bolt, the outside cover of lathe chuck is equipped with annular circle, fixedly connected with three bellying on the annular circle. This a positioner for lathe chuck through setting up annular circle, gim peg, screens strip and screens piece, rotates annular circle and drives bellying and bolt position correspondence, and screens strip displacement laminating is at the back of screens piece simultaneously, and the rethread gim peg gets into the screw hole, because screens strip and screens piece block this moment, and bellying laminating is on lathe chuck in addition, then can keep both sides fixed disk and lathe chuck, and then can improve connection stability, reduces the bolt and takes place not hard up and lead to the problem of connection inefficacy. The device in above-mentioned patent is through penetrating screw hole connection fixed disk and lathe chuck with the bolt, and the bolt hole is seted up on lathe chuck surface, if fixed disk and lathe chuck laminating department lack effectual limit control, under the great centrifugal force effect that the lathe high-speed rotation produced, can appear relative slip between fixed disk and the lathe chuck, not only can reduce machining precision, still probably causes the potential safety hazard. Disclosure of utility model (One) solving the technical problems The utility model provides a machine tool chuck positioning device aiming at the problems existing in the prior art. (II) technical scheme The machine tool chuck positioning device comprises a positioning outer frame, wherein a positioning mechanism is arranged on one side of the positioning outer frame; The positioning mechanism comprises a positioning disc and a limiting groove, wherein the limiting groove is respectively formed in the front end surface of the positioning disc and penetrates through the inside of the positioning disc, a limiting block and a nut column are respectively clamped in the limiting groove, first bolt holes penetrating through the inside of the positioning disc and the inner wall of one end of the limiting groove are respectively formed in the rear end surface of the positioning disc, and bolt rods are respectively connected between the first bolt holes and the inner wall of the nut column in a screwed mode.
