Description
Technical field
The present invention relates to a kind of fixture, particularly relate to a kind of casting mould upset jaw.
Background technology
Twentieth century twenties, flourish along with machinery industry, starts in machine-building to occur automatic production line.Owing to needing more exchange device in the middle of casting process, and casting mould carries out the processing of all directions, therefore in the middle of casting automatic production line, casting mould shifts and overturns by a very important ring exactly on a production line, need first to live casting mould by holder, carry out again by driving system, casting mould being passed on, finally by fixture, casting mould is overturn.Because the heavier-weight of casting mould, volume are comparatively large, adopt common clamping turnover fixture to finish the work, therefore need a kind of upset jaw that can be used in large weight and the upset of large volume casting mould.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of jaw that can be used in clamping, overturning casting die.
Technical scheme of the present invention is as follows: a kind of foundry production line upset jaw, comprise the jaw crossbeam (1) of " work " font, described jaw crossbeam (1) both sides are separately installed with mobile motor (2) and electric rotating machine (3), this mobile motor (2) and electric rotating machine (3) are fixed on jaw crossbeam (1) respectively by motor cabinet (4), the output shaft of described mobile motor (2) and electric rotating machine (3) is all set with output shaft gear (30), the mobile gear wheel (5) that this output shaft gear (30) is installed with jaw crossbeam (1) homonymy is respectively meshed, two mobile gear wheels (5) are set on the power transmission shaft (6) of jaw crossbeam (1) both sides, described power transmission shaft (6) is horizontally disposed along jaw crossbeam (1) length direction, the two ends, left and right being positioned at the power transmission shaft (6) of mobile motor (2) side are coaxially connected with screw mandrel (9) by adapter sleeve (8), the screw mandrel (9) at two ends has all been threaded nut (10), two nuts (10) are fixedly connected on two nut seats (11) respectively, this nut seat (11) below is fixedly connected with gripping arm body (12) by fixed block (32), two gripping arm bodies (12) are installed in jaw crossbeam (1) below, the both sides, top of described gripping arm body (12) extend upwardly to jaw crossbeam (1) both sides and are connected with clamping plate (13), the lower surface of these clamping plate (13) is also fixedly connected with track filler strip (14), two are close to the upper surface being fixed on jaw crossbeam (1) base plate by the lower surface of track filler strip (14), the lower end of two gripping arm bodies (12) is all connected with spiral case (24), upset latch (15) is had by bearing level connection joint in described spiral case (24), two upsets latch (15) are arranged in opposite directions, power transmission shaft (6) two ends, left and right being positioned at electric rotating machine (3) side are coaxially connected with upset transmission connecting shaft (16) by adapter sleeve (8), two upsets transmission connecting shaft (16) are all provided with rotating mechanism, the top of described rotating mechanism is connected to the rear side at gripping arm body (12) top, and the bottom of rotating mechanism extend in spiral case (24) also to overlap and installs in upset latch (15).
Use the upset jaw of said structure, during use, first drive mobile motor, the output shaft shaft gear that mobile motor output shaft is set with is made to drive the mobile gear wheel of this side to rotate, thus drive power transmission shaft and screw mandrel to rotate, just drive the nut on two transmission connecting shafts to move left and right along screw mandrel length direction, the distance between two gripping arm bodies is reduced, by the upset latch of gripping arm body lower end by the workpiece firm grip between two gripping arm bodies.When needs upset workpiece, drive electric rotating machine, the output shaft shaft gear that electric rotating machine output shaft is set with is made to drive the mobile gear wheel of this side to rotate, thus thus drive power transmission shaft and upset transmission connecting shaft to rotate, finally make rotating mechanism that upset transmission connecting shaft is installed drive upset latch to rotate.Adopt this structure, by two transportable gripping arm bodies, gripping can be carried out by the casting mould larger to volume, simultaneously because gripping arm body hangs over bottom jaw crossbeam, the casting mould of gripping heavier-weight can be used for.Pass through rotating mechanism in advance to the upset of casting mould simultaneously.
Described rotating mechanism comprises Bevel Gear Seat, by bearing, intermeshing horizontal transition bevel gear (17) and vertical transition bevel gear (20) are installed in this Bevel Gear Seat (19), described horizontal transition bevel gear (17) kink is in upset transmission connecting shaft (16), two upper equal levels of upset transmission connecting shaft (16) offer level trough (16a), T-shaped key (18) is installed in described level trough (16a), this T-shaped key (18) one end is positioned at level trough (16a), the other end and horizontal transition bevel gear (17) are fixedly linked, described vertical transition bevel gear (20) is positioned at upset transmission connecting shaft (16) below, this vertical transition bevel gear (20) center is equipped with worm screw spindle (21), described worm screw spindle (21) passes Bevel Gear Seat (19) straight down, and be coaxially connected with worm screw (22), this worm screw (22) is meshed with worm gear (23), described worm gear (23) is positioned at the spiral case (24) that gripping arm body (12) below is installed, and be solidly set in upset latch (15).Use the rotating mechanism of said structure, when overturning, upset transmission connecting shaft rotates, because horizontal transition bevel gear is by being connected with upset transmission connecting shaft, therefore, horizontal transition gear can be driven by gripping arm body and move along upset transmission connecting shaft length direction, rotate simultaneously, horizontal transition bevel gear and vertical transition bevel gear are meshed, by power transmission to vertical transition bevel gear, thus drive the worm screw spindle of vertical transition bevel gear clock center suit to rotate, the worm screw below worm screw spindle is driven to rotate, worm and wheel is meshed, worm gear is just driven to rotate, because worm gear is solidly set on upset latch, the final upset latch that just drives rotates, make two to overturn the middle casting mould held out against of latch to rotate.
