Abstract
The utility model provides a thread rolling apparatus matched with a machine tool. The utility model comprises a transmission mechanism, a base, a left and a right thread rolling wheel carriers and clamping feed mechanisms installed on the upper ends of the left and the right thread rolling wheel carriers, wherein, the left and the right thread rolling wheel carriers are connected with the base through coupling spindles; cutter frame holes are respectively arranged on the corresponding height of the left and the right thread rolling wheel carriers, and a left and a right cutter bars where thread rolling wheels can be installed are respectively installed in the cutter frame holes of the left and the right thread rolling wheel carriers and are connected with the transmission mechanism. The utility model has the advantages of simple structure, centering roll extrusion, synchronous rolling, convenient cutter alignment operation and use and high machining precision and efficiency, and is especially suitable for workpieces of which spindles and screw threads require high concentricity.
Description
The utility model relates to a kind of and the supporting rolled thread device of lathe.
Machining screw also adopts lathe grinding processing except that machining screw on screw-rolling machine now.Adopt the screw-rolling machine machining screw, can not guarantee the axiality of work piece, be not suitable for processing request axle and the high workpiece of screw thread concentricity.And adopting lathe grinding processing, work efficiency is low, machining accuracy is not high.
In view of above reason, the purpose of this utility model be for provide a kind of simple in structure, easy for operation, work efficiency is high, machining accuracy is high, can guarantee the rolled thread device of the concentricity of work piece axle and screw thread.
The utility model is achieved like this: transmission mechanism is arranged in the utility model, base, a wheel carrier that rolls left that is connected with base by coupling spindle, right rolled thread wheel carrier, be contained in the clamping feed mechanism of left and right sides rolled thread wheel carrier upper end, on the corresponding height of left and right sides rolled thread wheel carrier, be respectively equipped with the knife rest hole, the left knife bar of cylindrical die roll can be housed, right knife bar is contained in respectively in the knife rest hole on the left and right sides rolled thread wheel carrier and with transmission mechanism and links to each other (referring to Fig. 1, Fig. 2), during work, the utility model is placed on the lathe (as lathe), work piece is placed on machine tool chief axis chuck and the afterbody thimble, start lathe, power passes on the work piece through lathe, the work piece rotation drives the cylindrical die roll that is contained on the knife bar of the left and right sides and does the roll extrusion cutting with respect to work piece, rolled thread crop rotation roll extrusion cutting, clamp feed mechanism and make radial feed, up to completion of processing, work efficiency height, work piece axle and screw thread concentricity height.
Above-mentioned transmission mechanism comprises identical left gear, the right gear of parameter that is contained in respectively on the knife bar of the left and right sides, when being contained on the coupling spindle and the idler gear of left and right sides gears engaged (referring to Fig. 1), can guarantee synchronous rolling, the precision height.
Above-mentioned clamping feed mechanism comprises the pull bar that is contained on the left and right sides rolled thread wheel carrier, be contained on the pull bar and be positioned at spring between left and right sides rolled thread wheel carrier, pull bar stretches into a end in the right rolled thread wheel carrier and is connected an end that stretches out a wheel carrier that rolls left by connector with right rolled thread wheel carrier eccentric cam handgrip (referring to Fig. 1) is housed, adopt the eccentric cam handgrip, exert oneself little and power that produce is big, laborsaving.
Position-limit mechanism (referring to Fig. 1) is housed on the above-mentioned rolled thread wheel carrier.
The screw rod that is threaded with right rolled thread wheel carrier is arranged in the above-mentioned position-limit mechanism, and an end of screw rod stretches to and rolls left a wheel carrier and moving rod (referring to Fig. 1) is housed on the other end, adjusts screw rod and just can play spacing effect.
Above-mentioned left and right sides rolled thread wheel carrier and coupling spindle are for movingly, but self-centering.
The utility model is simple in structure, adopt the centering roll extrusion, synchronous rolling, tool setting are easy for operation, machining accuracy height, efficient height, is particularly suitable for axle and the high workpiece of screw thread concentricity requirement.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1: the utility model structural representation
The A-A cutaway view of Fig. 2: Fig. 1
The left view of Fig. 3: Fig. 1
Can find out that from Fig. 1-Fig. 3 transmission mechanism 1 of the present utility model is by synchromesh gear 2,3, form with the idler gear 4 of gear 2,3 engagement respectively.Coupling spindle 22 is through idler gear 4 successively, left and right sides rolled thread wheel carrier is contained on the base 7 in the hole of the wheel carrier 5 that rolls left, right rolled thread wheel carrier 6 and base 7.On the equal height of left and right sides rolled thread wheel carrier, be respectively equipped with left knife rest hole 8, right knife rest hole 9.Left knife bar 10, the right knife bar 11 that cylindrical die roll can be housed is through respectively in the knife rest hole, the left and right sides on gear 2,3 and the left and right sides rolled thread wheel carrier and is contained in respectively on the left and right sides rolled thread wheel carrier, and left and right sides rolled thread wheel carrier and coupling spindle are for movingly.
A hole and an end that pull bar 13 in the clamping feed mechanism 12 passes on the left and right sides rolled thread wheel carrier successively are close to by connector 14 and right rolled thread wheel carrier.Eccentric cam handgrip 15 is housed on the other end of pull bar 13.Be positioned at pull bar 13 packing ring 16, spring 17, packing ring 18 are housed on the left and right sides rolled thread wheel carrier successively.
Screw rod 20 1 ends in the position-limit mechanism 19 are threaded with right rolled thread wheel carrier 6 and stretch out right rolled thread wheel carrier sensing and roll left a wheel carrier 5 and moving rod 21 is housed on the other end.
