Description
Technical field
The utility model relates to the device that a kind of workpiece transmits on different station, belong to the press technologies field.
Background technology
In the prior art, utilize the forcing press processing work often to need multiple working procedure, repeatedly punching press could be shaped, and the conversion of workpiece between station and station is absolutely necessary, at present, all adopt pneumatic suction feeding or electromagnetism suction feeding style, form negative pressure by suction air and hold workpiece, or hold workpiece, be passed to next station again by electromagnet, after workpiece release, carry out punching press again.Its weak point is: for the pneumatic suction feeding, if there is not the face that can adsorb, then be difficult to work; For electromagnetism suction feeding, if workpiece is a non-ferrous material, then can not draw, prior art requires height to lathe and feed mechanism harmony, causes misoperation easily, and the station conversion interval time is long, influences production efficiency.
The utility model content
The purpose of this utility model provides a kind of hitch feed mechanism, makes the synchronism of feed mechanism and lathe good, the production efficiency height, and misoperation is few.
The purpose of this utility model is achieved in that a kind of hitch feed mechanism comprises fuselage, power transmission shaft, cycloidal cam, roller, slide block, slide bar, clamping bar and anchor clamps; Cycloidal cam is fixed on the power transmission shaft, and described slide block has two, and two slide block relative fixed also are arranged at the left and right sides of cycloidal cam respectively, and two slide blocks are provided with roller, and described roller contacts with cycloidal cam; Each slide block is equipped with fairlead in both sides up and down, and fairlead is socketed on the guide post, guide post and fuselage relative fixed; Clamping bar and slide block relative fixed, described clamping bar has two, be provided with some anchor clamps between described two clamping bars, spacing between the adjacent anchor clamps equals the poor of the maximum radius of cycloidal cam and least radius, each anchor clamps comprises last collet and the following collet that cooperatively interacts, and last collet, following collet are arranged at respectively on two clamping bars.
The utility model can be arranged on the workbench of forcing press, make fuselage and press bench relative fixed, the patrix of forcing press is arranged at the anchor clamps top, the counterdie of forcing press is arranged at the anchor clamps below, when work, with piece-holder between two collets of every pair of anchor clamps, when forcing press is worked, can adjust power transmission shaft and forcing press synchronous operation, it is forcing press running one-period, power transmission shaft also moves a week, and the two phase difference is consistent, when the upper punch of forcing press is pressed onto workpiece, cycloidal cam is in the starting point at isometrical place, at this moment, cam rotates and workpiece does not move, and forcing press is in the worker and advances state, turn over isometrical terminal point until cam, cam is rotated further and promotes slide block and moves along slide bar, and collet and workpiece are broken away from, and cam continues to turn over 180 when spending again, workpiece is snapped between the collet of next station, this moment, patrix withdrawed from, and cam is rotated further, and then drove the clamping bar motion, clamping bar promotes workpiece to next station motion, when workpiece motion s arrived next station, the forcing press patrix was depressed once more, finishes a working cycles.Such workpiece in working cycles one by one with workpiece constantly from a station transfer to next station, and constantly push the clamping bar other end to from clamping bar one end, in workpiece passed on process, workpiece was by repeatedly punch forming of patrix.The utility model hitch feed mechanism, owing to adopt mechanical type to connect, so the synchronism of feed mechanism and lathe is good, the accuracy that workpiece is transferred to next station depends on manufacturing and installation accuracy, in the process of passing on, can not produce misoperation, the action accuracy height, the work dead time is short, thereby the production efficiency height.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of Fig. 1.
Wherein, 1 clamping bar, 2 fuselages, 3 rollers, 4 cycloidal cams, 5 power transmission shafts, 6 guide posts, 7 slide blocks, collet on 8,9 times collets.
The specific embodiment
As figure, hitch feed mechanism is mainly by fuselage 2, power transmission shaft 5, cycloidal cam 4, roller 3, slide block 7, slide bar, clamping bar 1 and anchor clamps; Cycloidal cam 4 is fixed on the power transmission shaft 5, and described slide block 7 has two, is arranged at the left and right sides of cycloidal cam 4 respectively, and roller 3 is connected on the slide block 7, and described roller 3 contacts with cycloidal cam 4; Each slide block is equipped with fairlead in both sides about in the of 7, and fairlead is socketed on the guide post 6, guide post 6 and fuselage 2 relative fixed; Clamping bar 1 and slide block 7 relative fixed, described clamping bar 1 has two, be provided with some anchor clamps between described two clamping bars 1, spacing between the adjacent anchor clamps equals the poor of the maximum radius of cycloidal cam 4 and least radius, each anchor clamps comprises last collet 8 and the following collet 9 that cooperatively interacts, last collet 8, following collet 9 are arranged at respectively on two clamping bars 1, respectively are provided with spring between last collet 8, following collet 9 and the clamping bar 1, and described spring is conflicted at the chuck back side.
In use, hitch feed mechanism is arranged on the workbench of forcing press, bearing and hydropress frame relative fixed, the patrix of forcing press is arranged at the chuck top, the counterdie of forcing press is arranged at the chuck below, when work, with piece-holder between two chucks of every pair of anchor clamps, when forcing press is worked, can adjust forcing press, make itself and power transmission shaft 5 synchronous operations, it is forcing press running one-period, power transmission shaft 5 also moves a week, and the two phase difference is consistent, when the upper punch of forcing press is pressed onto workpiece, cycloidal cam 4 is in the starting point at isometrical place, at this moment, cam rotates and workpiece does not move, and forcing press is in the worker and advances state, turn over isometrical terminal point until cam, cam is rotated further and promotes slide block 7 and moves along slide bar, and chuck and workpiece are broken away from, and cam continues to turn over 180 when spending again, workpiece is snapped in the chuck of next station, this moment, patrix withdrawed from, and cam is rotated further, and then drove clamping bar 1 motion, clamping bar 1 promotes workpiece to next station motion, when workpiece motion s arrived next station, the forcing press patrix was depressed once more, finishes a working cycles.Such workpiece in working cycles one by one with workpiece constantly from a station transfer to next station, and constantly push clamping bar 1 other end to from clamping bar 1 one ends, in workpiece passed on process, workpiece was by repeatedly punch forming, and the workpiece after the moulding comes off from clamping bar 1 end.
