Description
Technical field
The utility model is related to a kind of lathe protector, specifically a kind of dropproof dress of heavy machine tool balance weight
Put.
Background technology
For heavy machine tool, because the rack construction of lathe is relatively large, no matter the moving parts of lathe is from shape
Or it is all relatively large, heavier in weight.In order to improve the performance and capability of fast response of lathe, while being passed to correlation
Dynamic component is protected, and for vertical shift and the larger moving parts of quality, counterweight treatment must be generally done to it, that is, be equipped with one
The balance weight body of individual similar weight therewith, carrys out all or part of weight for balancing moving parts, makes the driving of vertical shift part
System load reduces.
Heavy horizontal-type milling-boring machine just belongs to such lathe, and not only the stroke of each numerical control feeding axle is long, and moving parts matter
Amount is heavier.For example, for the Y-axis of heavy horizontal-type boring and milling machine, more than 4 meters, the weight of main shaft box unit is or not ordinary circumstance down stroke
Less than 15 tons, the balance weight for matching therewith be the structure that is connected with main spindle box after one group of steel wire rope bypasses fixed pulley group come
Realize counterweight.There is certain potential safety hazard in this structure, in lathe normal operation, due to steel wire rope and fixed pulley
Group produces friction, and steel wire rope is used for a long time, and wear phenomenon occurs unavoidably, if failure to inspect or inspection are not in time, will go out
Existing wire cable rupture phenomenon (in real work, wire cable rupture phenomenon happens occasionally), although main spindle box can be by motor
The form of the locked leading screw of band-type brake prevents falling for main shaft box assembly, but balance weight can directly and quickly fall in lathe
On, this will produce extremely serious safety consequences, damage the lathe bed or slide of lathe.
The content of the invention

The first mounting ring is provided with, the bottom wall of described connecting seat is provided with the second mounting ring, and described the second mounting ring is located at described
First support arm lower section, the two ends of described back-moving spring are separately mounted to described the first mounting ring and the second described peace
On dress ring, the end of described second support arm is connect by the second rotating shaft with one end axle of steel wire rope, described steel wire rope it is another
End is connected after bypassing fixed pulley group with main spindle box, under normal operating conditions, steel wire rope pull-up rotor, and rotor is limited, multiple
Position spring is stretched；Work as wire cable rupture, balance weight falls, rotor loses the drawing of steel wire rope, back-moving spring is pulled and turned
Kinetoplast is turned round, and first support arm is tilted, and with the whereabouts of balance weight, first support arm is blocked by a boss in multiple boss, from
And balance weight stops falling.
After the utility model fall-proofing device is installed and used on heavy machine tool, the safety of heavy machine tool can be effectively improved
Property.After steel wire rope is surprisingly broken, first support arm is blocked by a boss in multiple boss, due to balance weight movement by
Two guide rail supports, it is ensured that balance weight does not produce inclination in machine pillar, and stop at no longer to fall at the boss, because
This, even if wire cable rupture, the fall-proofing device can also play in time, be effectively protected effect, prevent because balance weight is direct
Fall and the lathe bed or slide of lathe are caused to damage.The utility model fall-proofing device helps to improve the protection of heavy machine tool
Measure, lifting heavy machine tool security in process of production, eliminates the trouble and worry of heavy machine tool user, improves heavy machine tool
The competitiveness of product in market.
Four groups of guide rollers are installed, described in the wheel face of described four groups of guide rollers and two on described balance weight
Guide rail contact；Guide rail described in every is arranged on the inwall of described machine pillar by multiple bearings respectively.
Cushion hole is offered in boss described in each.
Described first support arm and the upper surface of described second support arm are plane, and the end of described first support arm sets
It is equipped with down convex hook portion.
Compared with prior art, the utility model has the advantage of：The heavy machine tool balance weight that the utility model is provided
It is fall-proofing device simple structure, safe and reliable, after being installed and used on heavy machine tool, the safety of heavy machine tool can be effectively improved
Property.After steel wire rope is surprisingly broken, first support arm is blocked by a boss in multiple boss, due to balance weight movement by
Two guide rail supports, it is ensured that balance weight does not produce inclination in machine pillar, and stop at no longer to fall at the boss, because
This, even if wire cable rupture, the fall-proofing device can also play in time, be effectively protected effect, prevent because balance weight is direct
Fall and the lathe bed or slide of lathe are caused to damage.The utility model fall-proofing device helps to improve the protection of heavy machine tool
Measure, lifting heavy machine tool security in process of production, eliminates the trouble and worry of heavy machine tool user, improves heavy machine tool
The competitiveness of product in market.
