Aperture of treatment cylinder cross is adjustable clamping apparatus

What this clamping apparatus is heavying repair and make the lathe such as C615, C616, C618, C620, C620-1, C630 is small procrastinate board when Gui Heng punchs workpiece is machined, guide screw mother and other circle are used. Have assemble and unassemble clamp of convenient, fixed position reliable, operation is handy wait for an advantage, efficiency is 10 times taller than be being installed with 4 ungual chuck above. Graph in 1 workpiece sketch map is made in the machine tool or be being repaired, often encounter the workpiece of horizontal on cylinder perforation, if pursue,1 is shown. The central line of the aperture of these workpiece or whorl aperture and columnar central line do not intersect, need to be assembled after the car is very columnar, draw the positional line of good aperture, machine aperture or whorl by the line again. Previously. After workpiece draws fine line, with 4 claw chuck undertakes installing by the line, the aperture inside rework. In corrective process, when adjusting the two claw that are placed on columnar face, workpiece produces roll, make the central line that underlines aperture produces angle displacement, very difficult workpiece corrective, and generation processes waste product. For this, design the fixture that the manufactory shows 2 times like the graph, through the use that comes 30 years, the effect is very good. 1.

Lathe tailstock tip pursues Kong Ke of 2 columnar cross moves clamping apparatus to use a method: According to the size of columnar diameter outside workpiece, the snail annulus that adjusts clamping apparatus back end 1, the fixed position that the purpose makes clamping apparatus medium is top 14 with bedspring 2, when workpiece locates, have certain axial thrust and workpiece installation firm, taut pull rod 13 hind, fixed position tip the space that 14 have 10 ～ 15mm with workpiece, facilitate the knife is retreated when the whorl inside treatment. Thrust authority of clamping apparatus awl next inside aperture of lathe main shaft, twist on pull rod 13, loose two V claw, the fixed position in reoccupy clamping apparatus is top 14 with lathe tailstock tip 18, in carrying the central aperture that punchs in workpiece horizontal stroke on the head, pigheaded move two clamp guide screw 10, make two claw near the columnar surface of workpiece, see V claw the columnar face distance of two flank and workpiece is equal. When differring like the distance, handwheel of jolty lathe tailstock, have the aid of the bedspring force at back end of fixed position tip, will adjust them the distance between, make agree basically, again take turns thrust augmentation is pigheaded move two clamp guide screw, workpiece clamp. Removed lathe tailstock, screw the pull rod mother of main shaft back end, the fixed position in making pull rod drives clamping apparatus moves after the tip, leave work, compress bedspring, will whole clamping apparatus is taut, completed workpiece installation. Note: Before installing workpiece, should draw workpiece appropriately the central aperture after the line, the intention is strong increase a few, when clamp, should notice thrust augmentation of pair of take turns of two clamp guide screw, make in order to prevent workpiece displacement; When bore, the attention does not want to get fixed position tip. What this clamping apparatus is heavying repair and make the lathe such as C615, C616, C618, C620, C620-1, C630 is small procrastinate board when Gui Heng punchs workpiece is machined, guide screw mother and other circle are used. Have assemble and unassemble clamp of convenient, fixed position reliable, operation is handy wait for an advantage, efficiency is 10 times taller than be being installed with 4 ungual chuck above.
