free end of described locating detent push rod 20 is diminishing round table-like.In described housing 1, be provided with below locating detent fixed disk 12 and compress pawl fixed disk 13, described compression pawl fixed disk 13 comprises a disk (1301) and is in triangular distribution at three fixed blocks 1304 of described disk 1301 side, described disk 1301 center is provided with a through hole 1302, the sidewall of described through hole 1302 transits to disk 1301 end face by a sphere expanded gradually 1303, described fixed block 1304 upper surface is provided with circular hole 1305, the sidewall of described circular hole 1305 by a spherical transition expanded gradually to the bottom surface of fixed block 1304.The spiro rod section 1503 of clamp jaw fixed axis 15 bottom passes from the circular hole 1305 described fixed block 1304, be connected with clamp jaw hold-down nut 14, the end face of described clamp jaw hold-down nut 14 is a sphere, and the sphere on described sphere and described fixed block 1304 matches.The top of described clamp jaw fixed axis 15 is provided with circular hole 1501, and described circular hole 1501 communicates with the shaft hole 1502 be located on clamp jaw fixed axis 15.Described clamp jaw fixed axis 15 is hinged by a rotating shaft running through described shaft hole 1502 and the one end penetrating the clamp jaw that described housing 1 end face and sidewall stretch in housing 1.Described clamp jaw is triangularly arranged on the sidewall of housing 1, in order to better clamp part to be processed, described clamp jaw is designed to clamp jaw A2, clamp jaw B7 and clamp jaw C9 tri-kinds of difformities, its one end do not stretched in housing 1 of described clamp jaw is provided with clamp jaw push rod 19, general in order to realize right-hand man's part clamp, clamp jaw B7 is provided with two clamp jaw push rods 19.Described clamp jaw side is also provided with a tip chute, and the clamp jaw axis of guide 17 passes in described chute, and is fixed on housing 1.A pull bar 21 is also provided with in described fixture, described pull bar 21 is formed by connecting by four shaft parts, the shaft part of its topmost is a spiro rod section A2101, the larger cylinder shaft part A2102 of a diameter is connected below described spiro rod section A2101, described cylinder shaft part A2102 bottom connects the less cylinder shaft part B2105 of a diameter, aforementioned two shaft parts shrink transition from top to bottom gradually by a sphere 2103, a spiro rod section B2104 is connected below described cylinder shaft part B2105, spiro rod section A2101 in described pull bar 21 passes from the shoulder hole locating detent fixed disk 12 and disc spring 24 center from bottom to top, and be connected with pull bar end cap 22, sphere 2103 in described pull bar 21 cooperatively interacts with the sphere 1303 on described clamp jaw fixed disk 13, cylinder shaft part B2105 in described pull bar 21 penetrates the through hole 1302 of clamp jaw fixed disk 13 center, spiro rod section B2104 in pull bar 21 passes from this through hole 1302, be connected with the threaded one end of pull bar fixed cover 11.
During use, first by fixture by being arranged on housing 1 end face and fixture is fixed on lathe by the fixed screw 6 running through housing 1, the non-link of the pull bar on lathe and pull bar fixed cover 11 is linked together.Then by the boss top of part to be processed as described back-up block, the screw rod on positioning seat 3 at the beginning of adjusting three, makes part Primary Location.Then lathe is opened, lathe pull bar is moved downward, thus drive clamp pull rod 21 to move downward, clamp pull rod 21 moves downward and drives locating detent fixed disk 12 and clamp jaw fixed disk 13 to move downward again simultaneously simultaneously, because two fixed disks move downward, drive two cover claws to move downward, owing to two cover claws being equipped with guide chute and the guiding rotating shaft of inclination, the interaction between them makes two cover claws inward collapsible while thinking lower motion simultaneously.Because the stroke ratio clamp jaw of the locating detent 4 pre-set is short, this makes locating detent 4 first contact part, makes part complete location under three points centering effect.Along with pull bar 21 is descending, pull bar end cap 22 gradually reduces disc spring 18, makes locating detent 4 pairs of parts apply certain location clamping force.Pull bar 21 continues descending, and now clamp jaw also closes up completely, and clamp jaw push rod 19 pairs of parts apply enough clamping forces, this completes the clamping work of part.
Compared with prior art, the utility model has following beneficial effect: the utility model realizes location and clamping function respectively by two collets, thus not only ensure that accurate positioning, ensure that enough clamping forces simultaneously.Adopt disc spring to provide locating detent clamping force simultaneously, make the adjustment of locating detent clamping force very convenient.All adopt spherical pair to be connected between pull bar with clamp jaw fixed disk and between clamp jaw hold-down nut with clamp jaw fixed disk and make clamp jaw automatically can adapt to the out-of-flatness situation on part blank surface, thus stable effective clamping force is provided.This fixture can be controlled the folding of two collets by lathe pull bar simultaneously, easy to use, reduces the labour intensity of workman.This fixture also achieves part second self general, has saved production cost.
Below the utility model has been described in detail, but the utility model is not limited to detailed description of the invention described herein.It will be appreciated by those skilled in the art that when not deviating from the utility model scope, other changes and distortion can be made.Protection domain of the present utility model is defined by the following claims.
