Abstract

The utility model relates to a die rapid clamping device, which comprises a screw bolt. The clamping device is characterized in that a polyurethane cushion ring is sleeved on the screw bolt, a steel plate cushion ring is sleeved on the screw bolt and is located on the polyurethane cushion ring, a rotary shaft of an eccentric wheel is matched with a hole on the screw bolt, the eccentric wheel is contacted with the upper surface of the steel plate cushion ring, and a handle is arranged on a wheel rim of the eccentric wheel. Compared with the prior art, the utility model has the following advantages that the problem that a die uses a screw to clamp, which wastes time and labor, is solved, the die replacing time can be saved, and the die replacing labor intensity is lowered, and the production efficiency is increased.

Description

A kind of mould fast fixture
Technical field
The utility model relates to the automobile making mould, is specifically related to a kind of mould fast fixture.
Background technology
The production of the large-scale outer covering piece of automobile generally needs the 3-5 procedure, just means that also auto parts need the secondary mould punching press of 3-5 just can finish.At present, the hold down gag of automobile die on workbench all is to adopt screw/nut to fix, as shown in Figure 1.And every secondary mould needs 8 mould housing screws (each four of upper and lower moulds) that its mould is fixed on the punching machine work top at least, the operative employee on average fixes and dismantle a screw with spanner need 30 seconds, 8 is exactly 240 seconds, 4 secondary moulds are exactly 960 seconds, to a certain extent, time-consuming useless power has reduced production efficiency.
Summary of the invention
The purpose of this utility model provides a kind of mould fast fixture, and it can solve the problem that mould uses screws clamp to waste time and energy, and can save mould replacing time, reduces die change labour intensity, enhances productivity.
The purpose of this utility model provides a kind of mould fast fixture, comprises screw rod, it is characterized in that: be with a polyurethane packing ring on screw rod, a metal mat snare is on the screw rod and be positioned on the polyurethane packing ring; One eccentric rotating shaft cooperates with hole on the screw rod, and eccentric wheel contacts with the top of steel plate packing ring, is provided with handle on eccentric wheel rim.
Change nut into rubber-like polyurethane packing ring, on the polyurethane packing ring, fix a steel plate packing ring of making of the thick steel plate of 5mm,, play the effect of degree of tightness mould by eccentric rotation.
The utility model compared with prior art has the following advantages: solve the problem that mould uses screws clamp to waste time and energy, can save mould replacing time, reduce die change labour intensity, enhance productivity.
Description of drawings
Fig. 1 is the working state schematic representation of existing screw/nut clamping device.
Fig. 2 is a working state schematic representation of the present utility model.
The specific embodiment
Referring to Fig. 2, a kind of mould fast fixture described in the utility model comprises screw rod 1, is with a polyurethane packing ring 4, one steel plate packing rings 3 and is enclosed within on the screw rod and is positioned on the polyurethane packing ring on screw rod; The rotating shaft 2-1 of one eccentric wheel 2 cooperates with the hole on the screw rod, and eccentric wheel contacts with the top of steel plate packing ring 3, is provided with handle 2-2 on eccentric wheel rim;
During work, after screw rod 1 passes workbench 6 and mould 5 from bottom to top, polyurethane packing ring 4 is enclosed within on the screw rod 1, contact with the top of mould 5 below it, be enclosed within steel plate packing ring 3 on the screw rod and be positioned on the polyurethane packing ring, then, the rotating shaft 2-1 of eccentric wheel 2 is cooperated with hole on the screw rod, and eccentric wheel contacts with the top of steel plate packing ring 3, and the operative employee holds eccentric wheel rim and is provided with handle 2-2, when rotating eccentricity is taken turns to the A place, eccentric wheel contacts with the steel plate packing ring, according to the difference of the installation U type groove height of mould, when compressing between AC rotation adjust, rotation adjustment between AB when loosening, B, the C place is a bottom dead centre on the eccentric wheel.
