Specific embodiment
The utility model is directed to drawback of the existing technology, provides a kind of higher floor type boring machine cutter master of reliability
Shaft transmission case balancing device avoids lathe caused by falling because of balanced weight from scrapping accident to improve the safety of lathe operation.
Referring to Fig. 1, the utility model includes balanced weight 9, mechanical buffer unit 11 and multiple suspension units, each suspension unit
Including tension sensor 2, wirerope 4(or chain) and rope sheave 6(or sprocket wheel), the both ends of chain or wirerope 4 are separately connected knife
Has the self-locking device of main transmission box 1 and balanced weight 9, tension sensor 2 is installed on balanced weight 9 and connects on chain or wirerope suitably
Position, when 4 stress of wirerope is more than setting value, tension sensor 2 issues electric signal, this signal introduces the urgency of machine tool controller
Stop controlling in program, while acoustic-optic alarm can be added.
The utility model realizes the direct protection that chain or wirerope 4 are broken by tension sensor 2, and that directly protects is auxiliary
Helping device includes the control component such as relay and acoustic-optic alarm.
Mechanical buffer unit 11, which is installed in column 10, (also may be mounted at balanced weight on slide face corresponding to lower space
9 lower surface), which does not influence 9 lower bound range of balanced weight, when tension sensor 2 and balanced weight self-locking device surprisingly lose
When effect, 9 shock of a fall power are cut or polish jade with an emery wheel in 11 absorption equilibrium of mechanical buffer unit, avoid machine tool main body structural failure.
Referring to Fig. 2~Fig. 4, self-locking device 8 mainly include rope seat 13, connecting rod 14, lever 15, vertical compression bar 16, spring 17,
Sliding rail 18, horizontal pin shaft 19 hold block 20, guide plate 21 and self-lubricating abrasion-resistant set 22 tightly, and self-locking device is installed on balanced weight 9.
When cutter main transmission axle box moves up and down, since rope seat 13 is sequentially connected with connecting rod 14, lever 15, vertical compression bar 16, according to
Lever principle, spring 17 are compressed, and vertical compression bar 16 drives guide plate 21 to move down, and horizontal pin shaft 19 is in the oblique of guide plate
It is moved obliquely in sliding slot, promotes to hold block opening, when cutter main transmission axle box moves up and down, tubulose of the balanced weight in column tightly
Upright guide rail 7 moves up and down.Conversely, holding block closure tightly when wirerope is broken suddenly, embracing on upright guide rail, realize self-locking.
In 9 self-locking device of balanced weight, holds tightly and installed self-lubricating abrasion-resistant set 22 at the horizontal pin shaft 19 of block 20 additional.Because of lathe
It is used for a long time, easily causes to deform to form pit at the oblique sliding slot contact surface for holding block horizontal pin shaft 19 and guide plate 21 tightly, make
It holds block 20 tightly and acts card resistance, 9 self-locking device of balanced weight is caused to fail, it is final to cause lathe damage accident.After improvement, horizontal pin shaft
Rolling friction is improved to by original sliding friction between 19 and self-lubricating abrasion-resistant set 22, holding block movement card resistance is eliminated and causes
Balanced weight self-locking device fail hidden danger.Horizontal pin shaft covers size, weight according to the oblique chute size of guide plate and self-lubricating abrasion-resistant
Newly design and produce.
The utility model utilizes tension suffered by wirerope in each suspension unit of tension sensor real-time monitoring, ordinary circumstance
Under, multiple suspension units will not break down simultaneously, when individual suspension units break down, the wirerope of other suspension units
Or the tension of chain can significantly increase, and the tension of the wirerope of failure suspension unit or chain then reduces, machine tool controller root
Balanced weight falling risk can be judged whether there is according to the variation of each wirerope or chain tension, when part or all of wirerope
When power transfinites, machine tool controller keeps lathe out of service and alert, and maintenance personal is prompted to debug in time；
When mentioned strain sensor failure or wirerope are broken extremely, self-locking device can action message, realize and hold tightly
It is self-locking.Also, in the case where abnormal do not work occur in self-locking device, multiple suspension units, utilize mechanical buffer unit reality
Now final protection causes damages after preventing balanced weight from falling.The generation for effectively preventing balanced weight falling accident, ensure that and set
Standby and personnel safety.
The utility model improves balanced weight anti-falling self-locking device, by the safety guard of Multiple Combination, eliminates
The disadvantage of the prior art has prevented self-locking failure accidents caused by wearing because of self-locking device mechanical mechanism.
Compared with the existing technology, the utility model structure is simple, convenient for inspection, high reliablity, disposable investment and later period
Maintenance cost is low.
