The utility model discloses a kind of location material returned top, be characterized in, including top body (1), material returned block (2), reinforcing ring (3), fairlead (4) and thrust plate (5)；Described material returned block (2) is arranged in the trapezoidal guide slot on top body (1), reinforcing ring (3) is arranged on material returned block (2) front outer, material returned block (2) afterbody is connected on fairlead (4), thrust plate (5) is formed by upper and lower two pieces, by bolt card on fairlead (4), the two matched in clearance, thrust plate (5) relatively rotates with fairlead (4)；Thrust plate (5) or top body (1) are connected with external power supply；Top body is made to produce relative localization displacement with material returned block by external power supply, accurately workpiece can be released to setting position from top body, solve workpiece in automatic production line to be easily stuck on top and the problem of location difficulty after top upper release, and simple in construction, production cost is low.
Description
Technical field:
This utility model relates to lathe spare and accessory parts and machine equipment technical field, and specifically a kind of location material returned is top.
Background technology:
Top is that in machining, equipment commonly uses machine equipment, is particularly widely used in the processing of cast workpiece.Traditional top location that functions only as holds out against effect, and when processing cast workpiece, workpiece is easily stuck on top, and the at this moment release of workpiece typically requires other auxiliary body and realizes.The ejecting mechanism of auxiliary is usually and installs laterial translation mechanism below workpiece additional, drives workpiece from top disengaging, or is designed as tip holder to drive top be separated from workpiece with movable part.When the clamping force that workpiece is stuck on top is excessive, by the movement of both ejecting mechanisms, it is difficult to ensure that workpiece is completely from top upper disengaging, and push is it cannot be guaranteed that the position location of workpiece, the position error for the subsequent processing band in automated production.
Utility model content:
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, and provides a kind of location material returned top；Mainly solve workpiece in the automatic production line of prior art to be easily stuck on top and the problem of location difficulty after top upper release.
The technical solution of the utility model is: a kind of location material returned is top, and it is characterized in that, including top body, material returned block, reinforcing ring, fairlead and thrust plate；Described top body axial direction has trapezoidal guide slot, material returned block to be N number of, and material returned block is arranged in the trapezoidal guide slot on top body, and material returned block moves axially along top body；Described reinforcing ring is arranged on material returned block front outer, and material returned block afterbody is connected on fairlead, and fairlead coaxially moves with top body；Described thrust plate is formed by upper and lower two pieces, and by bolt card on fairlead, the two matched in clearance, thrust plate relatively rotates with fairlead；Thrust plate or top body are connected with external power supply.
Further, top described body cone has groove.
Further, described external power supply is hydraulic pressure, air pressure or other machine power.
Compared with the prior art the material returned is top in a kind of location described in the utility model has the positive effect that: 1, top body cone is with strengthening the groove of frictional force, can guarantee that when top tight workpiece the location of workpiece is stable；2, material returned block front end face directly acts on workpiece end face, and the utilization rate of thrust is high, it is possible to ensure that workpiece completely disengages from；3, by the release distance of external power supply, can set the release distance of material returned block accurately, it is ensured that the position that can navigate to preset released by workpiece every time, that has saved workpiece relocates the time, improves automaticity；4, thrust plate and fairlead are connected by matched in clearance, it is ensured that the spinning movement of top body and the projecting motion of material returned block are independent of each other；5, the release component being made up of material returned block, reinforcing ring, fairlead and thrust plate is installed with top body fits, compact conformation, low cost.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the front view of Fig. 1；
Fig. 3 is the A-A profile of Fig. 2；
Fig. 4 is the B-B profile of Fig. 2.
Detailed description of the invention:
In order to be more fully understood that and implement, provide specific embodiment below in conjunction with the accompanying drawings and describe this utility model in detail.
Embodiment 1, sees Fig. 1,2,3,4, is processed into top body 1, material returned block 2, reinforcing ring 3, fairlead 4 and thrust plate 5 by design requirement；Top body 1 conical surface is milled with groove, increases the frictional force with workpiece, and be milled with trapezoidal guide slot at top body 1 axial direction, for the mobile guide of trapezoidal material returned block 2；Being arranged on by material returned block 2 in top body 1 trapezoidal guide slot, material returned block 2 is N number of, N >=3, and installs reinforcing ring 3 additional at the front outer of N number of material returned block 2, keeps multiple material returned block 2 synchronization action and strengthens material returned block 2 rigidity；Material returned block 2 afterbody is connected by screw on fairlead 4, and fairlead 4 keeps coaxially moving with top body 1 on top body 1；Thrust plate 5 is formed by upper and lower two pieces, and by bolt card on fairlead 4, the two matched in clearance, thrust plate 5 relatively rotates with fairlead 4；Thrust plate 5 is connected with external power supply；External power supply can be hydraulic pressure, air pressure or other machine power.
The structure of above-described embodiment 1, when external impetus makes thrust plate and top body when axially there is relative displacement, and fairlead moves axially along top body therewith, and the most top body of material returned block moves axially, thus release workpiece and navigate to a certain to determine position, it is achieved location material returned effect；When material returned block, reinforcing ring, fairlead rotate with top body, thrust plate geo-stationary.
The structure of above-described embodiment 1, when external impetus makes thrust plate and top body when axially there is relative displacement, and fairlead moves axially along top body therewith, and the most top body of material returned block moves axially, thus release workpiece and navigate to a certain to determine position, it is achieved location material returned effect；When material returned block, reinforcing ring, fairlead rotate with top body, thrust plate geo-stationary.
Embodiment 2, with embodiment 1, is a difference in that top body 1 is connected with external power supply.
The structure of above-described embodiment 2, when workpiece released by needs, external power supply drives top body 1 to exit back, and material returned block is released the distance set relative to top body, promoting workpiece to disengage the top body position to setting, then material returned block and top body return to initial position.
The foregoing is only preferred embodiment of the present utility model, the top structure being not merely defined in the present embodiment of positioned for the material returned involved by this utility model, any equivalent modifications carrying out this utility model and replacement are the most all in category of the present utility model.
