Abstract

The invention belongs to a kind of taper seat and tapered thread cutting machine, be characterized in workpiece is fixed on the anchor clamps, start the Motor Drive cutter around the knife bar high speed rotating, underspeed through gearbox by motor, drive conical die thread body and universal sliding joint mechanism, make knife bar again around the revolution of workpiece axial line, and the promotion motor case moves forward along axis B-B at a slow speed, form the conical spiral motion of cutter, finish the processing of taper seat or tapered tread with respect to workpiece.Its advantage is that workpiece does not change, and adapts to the termination screw thread processing of long column body workpiece, and volume is little, and is in light weight, is convenient to resettlement, can be at the building-site processing work.

Description

Taper seat and tapered thread cutting machine

The invention belongs to a kind of garden conical surface and garden taper thread cutting machine.

The existing garden conical surface and the processing of garden taper thread are set up pattern and are realized that in the process, workpiece rotates on engine lathe, this is difficult to accomplish for very long workpiece (for example a large amount of reinforcing bars that use on the building industry).

The purpose of the invention is exactly in order to address the above problem the technical scheme of proposition.

The characteristics of this programme are with workpiece 1(accompanying drawing 1) be fixed on the anchor clamps 26.Rotating screw bolt handle 15 and seat board handle 16 mix up the relative position between cutter 2 and the workpiece 1.Start motor, drive cutter 2 around knife bar 3 high speed rotating.By motor main shaft after gearbox 9 underspeeds, driving garden prod cast thread mechanism, make knife bar 3 in rotation, revolve round the sun around workpiece axial line A-A, and promote casing 4 along the regular reach at a slow speed of axis B-B, form the garden awl spiral motion of cutter 2, finish the processing of the garden conical surface or garden taper thread with respect to workpiece 1.

The advantage of this machine is that workpiece does not change, and is adapted to the processing of long column body (tubing, garden steel, square steel, hexagonal steel etc.) work end head thread; And volume little (with respect to lathe) is in light weight, is convenient to resettlement, can be at the building-site processing work.

Below for an embodiment, with reference to description of drawings:

Fig. 1, the garden conical surface and garden taper thread organisation of working stereogram;

Fig. 2, output shaft and spiral shell wheel slide block syndeton stereogram.

Workpiece 1 is fixed on the anchor clamps 26, and cutter 2(can be hilted broadsword or gang tool) be fixed on the knife bar 3, knife bar 3 is contained on the motor reel, and knife bar 3 is rotated at a high speed by Motor Drive.Knife bar axis B-B rotates around main shaft A-A for heart angle is α with O, and the movement locus of knife bar axis B-B is for being the garden conical surface on summit with O.Up and down two chutes 5 are arranged on the motor case 4, make the motor case 4 can be along axis B-B longitudinal sliding motion.Chute 5 and slide block 6 be for being slidingly connected, and the side of two slide blocks 6 has vertical slide block bearing pin 8 to be loaded in two holes of universal joint to movingly up and down, can rotate around the C-C axle.The two sides in addition of universal joint have two universal drive shaft Xiao 20 to be loaded in the hole of two supporting bases 21, can rotate around the D-D axis, and two supporting bases are fixed on the seat board 22.

Its rotating speed of the other end of motor reel through gearbox 9 from n ₁(at a high speed) become n ₂After (utmost point low speed), by output shaft 10 outputs, output shaft 10 is formed flexible connection by pivot pin 19 and spiral shell wheel slide block 18, spiral shell wheel slide block 18 is contained in the radial groove of runner nut 13, and the pushing that an interior end of spiral shell wheel slide block 18 is subjected to spring 14 is close on the inner conical surface of garden awl guiding shell 11 its other end all the time.Runner nut 13 is contained on the screw shaft 12 to being threaded, and screw shaft 12 removable mountings are on the hole of screw shaft supporting base 17, and the screw rod the tip of the axis is equipped with screw handle 15, can rotate by rocking-turn screw shaft 12.Screw shaft supporting base 17 is fixed on the seat board 22.Seat board 22 bottoms are connected with nut seat 23, nut seat 23 and seat board screw rod 24 are for being threaded, the other end of seat board screw rod 24 is loaded in the hole of support 25, the end of seat board screw rod 24 is equipped with seat board handle 16, shake seat board handle 16, the chute that seat board 22 is connected with support 25 along seat board 22 moves forward or retreats.
