Abstract
The utility model discloses a mould used for aided machining of an engine wheel tread. The mould used for the aided machining of the engine wheel tread comprises a stud bolt, a press plate, an upper plate and a disk-shaped mould body, the upper plate is fixed in the center of the top of the mould body, the lower end of the stud bolt is connected with the upper plate through threads, the upper end of the stud bolt penetrates through the press plate and is fixed through a hex nut, and according to the mould body, four hexagon head aided supports are evenly arranged on a circumference around the center. The mould used for the aided machining of the engine wheel tread has the advantages that the mould can be used for the aided machining of the engine wheel tread, with the match of other tools, positioning of the center of rotation of a wheel to be machined is more accurate in a clamping process, once, aided by the mould, the engine wheel tread is formed through machining, a wheel set pressing fit machine is adopted to install an axle, a driven gear and wheels into a wheel set in a pressing mode, the tread is formed through the machining without being placed on a tread lathe, a production cycle is shortened, and the quality of wheel set products is ensured.
Description
Technical field
The utility model relates to the mold technical field, particularly a kind of mold for secondary process locomotive wheel tread.
Background technology
Existing locomotive wheel is when the processing tread, and the technology mode of Cai Yonging is always: it is right earlier axletree, driven gear, pressure wheel to be dressed up wheel, shapes JM3 type tread at the tread lathe again.The major defect of this kind technology is: wheel needs multiple clamping, and production efficiency is low, and wheel is easy to cause the operation bottleneck to press-fiting difficult assurance of shaping back relative position size.This present situation for a change, improve the right production handling capacity of wheel, the wheelset fitting process is optimized, adopts the mold of locomotive wheel JM3 type tread processing, earlier wheel JM3 type tread is shaped, it is right axletree, driven gear, pressure wheel to be dressed up wheel again, behind the wheelset fitting, the relevant position size can satisfy Design Requirement Drawing fully, need not go up tread machined into shaping JM3 type tread again, saved the production cycle, guaranteed that wheel is to product quality.
The utility model content
Goal of the invention of the present utility model is: a kind of mold for secondary process locomotive wheel tread is provided, and match wheel is to the smooth implementation of press-loading process mode.
The technical solution adopted in the utility model is such: a kind of mold for secondary process locomotive wheel tread, comprise stud, pressing plate, upper plate and discoidal mold body, described upper plate is fixed on mold body center of top, described stud lower end is threaded with upper plate, the upper end is passed pressing plate and is fixed by hex nut, and described mold body is evenly arranging four turret head aiding supports on a circumference in the center of circle.
As preferred structure, the two ends, the left and right sides of stating mold body upper surface circumference respectively arrange a lifting bolt.
As preferred structure, described mold body upper surface circumferential edges arranges a circle screw hole, has a T type piece to pass from top to bottom in each screw hole and locks with hexagon socket cap head screw in T type piece upper end.
As preferred structure, described mold body center arranges the stud hole, and a circle screw hole is set around the stud hole, and upper plate is fixed in this circle screw hole by screw.
As preferred structure, described mold body is evenly arranging and four turret head bearing hole that the turret head aiding support is corresponding on a circumference in the center of circle, and turret head aiding support lower thread is connected in the turret head bearing hole.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: can be used for secondary process locomotive wheel tread, under the cooperation of some other instrument, make wheel to be processed pivot location in clamping process more accurate; In case auxiliary down at this mold, with the machine-shaping of locomotive wheel tread, adopt Press Fit Device for Wheelset, with axletree, driven gear, pressure wheel dress up wheel to after, just needn't go up tread machined into shaping tread again, saved the production cycle, guaranteed to take turns product quality.
