Description
Technical field
The utility model relates to a kind of metal clamp for machining, especially ring-shaped work pieces is carried out the special fixture of some five equilibrium cuttings.
Background technology
At present, the conventional method that the high-density alloy ring-shaped work pieces cuts into trisection is: three main shafts that are separately installed with cutting blade, on same circumference, separate 120 degree and be installed on the workbench and rotation simultaneously, workpiece with clamp after, one removes the cutter cutting.The increase that the accuracy of manufacture of lathe and manufacturing cost can be at double like this, and maintenance cost is quite high; In addition, because the part that will cut is very little, three suffer cutting blade very closely mutually, and operating personnel need SC when the loading and unloading part, thereby make operating efficiency to improve.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, a kind of improvement of cutting clamper is provided, these anchor clamps are clamping ring-shaped work pieces to be processed reliably, has the advantages that the lathe accuracy of manufacture is less demanding, processing cost is lower, production security is good.
The technical scheme that the utility model provides is: high-density alloy trisection cutting clamper, comprise the tubular of axis normal setting clamping fixture seat, be positioned at the workpiece locating piece of clamping fixture seat top, evenly be hinged on workpiece locating piece periphery some jaws, be positioned at the hinged leverage in clamping fixture seat central authorities and described some jaws bottom, be positioned at clamp base to the leverage application of force to unclamp the handle of jaw; It is characterized in that described clamping fixture seat is rotatably positioned in clip base by bearing, go back socket on the outer circumferential surface of clamping fixture seat bottom and fix an equi-index plate, the handle mechanism of a five equilibrium disk-positioning mechanism and a pair of equi-index plate application of force is set again around the equi-index plate.
Described leverage comprises a slide bar that can vertically move up and down, is set on and orders about the spring that slide bar moves upward on the slide bar; The bottom of described each jaw is hinged by the top of a connecting rod and slide bar respectively; The front end of described handle stretches into clamp base the bottom of slide bar is applied straight down pulling force.
Described equi-index plate periphery is made the trisection involute shape.
Comprise an alignment pin that can radially slide along equi-index plate in the described equi-index plate detent mechanism, and this alignment pin is applied pressure toward internal diameter direction so that the pinpoint stage clip of equi-index plate.
Described handle mechanism comprises a swivel becket that is positioned on the clip base and can rotates around clip base, the inserted link that is positioned on the swivel becket and reciprocatingly slides in the equi-index plate diametric(al), force in inserted link and make its top insert the little spring of equi-index plate groove, and force in the elastic strip that swivel becket makes that swivel becket rotates counterclockwise together with clamping fixture seat.
Operation principle of the present utility model is: whole anchor clamps are installed on the horizontal planker of a pair and (make anchor clamps slide into the processing district respectively and carry out machining, and slide into the clamping district and unload part and the clamping part to be processed of finishing processing), the handle application of force (arrow F direction) back makes three jaws unclamp part by the effect of leverage, and spring makes three jaws clamp part by the effect of leverage.
After part 10 was put the locating piece 9 of anchor clamps and gripped, operating personnel can pull swivel becket handle mechanism 20 with the hand clockwise direction, and equi-index plate 1 is rotated with clamping fixture seat 5; Treat that the alignment pin 2-1 of equi-index plate detent mechanism 2 slowly climbs up the involute surface of equi-index plate, alignment pin is jumped in the C place groove and just can be unclamped hand under the effect of stage clip 2-2; Because the inserted link 20-1 in the swivel becket handle mechanism has jumped in the A place groove under the effect of little spring naturally, so swivel becket handle mechanism is under the effect of elastic strip 19 (rubber band) pulling force, swivel becket is spurred toward counter clockwise direction together with equi-index plate, make the jag sidewall (the long radius position of equi-index plate) in equi-index plate C place left side) compress alignment pin, equi-index plate is just accurately located (gap of having eliminated simultaneously alignment pin and equi-index plate in the equi-index plate mechanism again), for the second time rolling clamp get ready; Operating personnel can promote to be equipped with the planker motion of whole anchor clamps then, making it enter the processing district treats processing parts and carries out first time cutting, after cutting is finished again pulling whole anchor clamps planker is housed withdraws from the processing district and arrive the clamping district, pull equi-index plate once more as stated above and clamping fixture seat rotates together; So repeat, cut into trisection until part.
The beneficial effects of the utility model are: because manually trisection rotation of anchor clamps, thereby lathe only needs a cutting spindle, and cutting accuracy guarantees by the accuracy of manufacture of anchor clamps, reduces significantly for the required precision of lathe, and then significantly reduced manufacturing cost; Operating personnel's job safety has also had certain assurance simultaneously.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is that P-P among Fig. 1 is to structural representation.
