Description
Technical field
What the present invention relates to is machine industry, is specially a kind of screw mandrel and holds up mechanism.
Background technology
Widely-used screw mandrel in existing lathe, if two fixing points distances of lathe upper screw rod are far away, diameter is bigger, will have the screw mandrel sag, influences the life-span of the running precision and the screw mandrel of lathe.
Summary of the invention
The purpose of this invention is to provide a kind of reliable, safe screw mandrel and hold up mechanism, solve the sagging problem of screw mandrel, improve lathe running precision and screw mandrel life-span.
Technical solution of the present invention is: a kind of screw mandrel holds up mechanism; Comprise nut, hold up spring, guide rod a, guide rod b, guide pin bushing a, guide pin bushing b, carriage, briquetting roller a, briquetting roller b, briquetting a, briquetting b, supporting rollern a, supporting rollern b, push rod and supporting base; Supporting base and guide pin bushing a, guide pin bushing b are fixed on the lathe base; Push rod, picking-up spring and pre-load nut are contained in the supporting base, and guide rod a is connected with carriage with guide rod b, in guide pin bushing a and guide pin bushing b, moves up and down respectively; Briquetting roller a, briquetting roller b and supporting rollern a, supporting rollern b are installed on the carriage, briquetting a and briquetting b be fixed on the platen; Described briquetting roller a, briquetting roller b are installed in the carriage both sides respectively, and its rotation direction is identical with the screw mandrel axial direction; Described supporting rollern a, supporting rollern b are installed in the groove in the middle of the carriage, and its rotation direction is identical with the screw mandrel radial direction.
Advantage of the present invention is following: can reduce the sag of chain of screw mandrel, improve the running precision of lathe and the life-span of screw mandrel.
Description of drawings
Below in conjunction with accompanying drawing and enforcement principle the present invention is further specified.
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in fig. 1; A kind of screw mandrel holds up mechanism; Comprise nut (1), hold up spring (2), guide rod a (3), guide rod b (4), guide pin bushing a (5), guide pin bushing b (6), supporting base (7), briquetting roller a (8), briquetting roller b (9), briquetting a (10), briquetting b (11), supporting rollern a (12), supporting rollern b (13), push rod (14) and carriage (15); Supporting base (7) and guide pin bushing a (5), guide pin bushing b (6) are fixed on the lathe base; Push rod (14), picking-up spring (2) and nut (1) are contained in the supporting base (7); Guide rod a (3) is connected with carriage (15) with guide rod b (4); Move up and down at guide pin bushing a (5) and guide pin bushing b (6) respectively, briquetting roller a (8), briquetting roller b (9) and supporting rollern a (12), supporting rollern b (13) are installed in the carriage (15), briquetting a (10) and briquetting b (11) and be fixed on the platen.
Concrete operation principle: push rod (14) is jack-up carriage (15) under the effect that holds up spring (2); Supporting rollern a (12) contacts with screw mandrel in supporting rollern b (13) is fixed on the middle groove of carriage (15) and rotates with screw mandrel; Guide rod a (3) and guide rod b (4) are fixing with carriage (15), in guide pin bushing a (5) and guide pin bushing b (6), move respectively, make carriage (15) moving up and down; Briquetting a (10) and briquetting b (11) are fixed on the platen; When movable workbench to this mechanism, briquetting a (10) and briquetting b (11) are pressing briquetting roller a (8) and briquetting roller b (9) to move down to dodge out workbench, after workbench passes through this mechanism respectively; Briquetting a (10) and briquetting b (11) leave briquetting roller a (8) and briquetting roller b (9); Carriage (15) is homing under the effect that holds up spring (2), and supporting rollern a (12) is contacted with screw mandrel with supporting rollern b (13), holds screw mandrel and prevents that screw mandrel is sagging.
