Specific embodiment
The present invention is directed to drawback of the existing technology, provides a kind of higher floor type boring machine cutter spindle biography of reliability
Dynamic 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 present invention includes balanced weight 9, mechanical buffer unit 11 and multiple suspension units, and each suspension unit includes
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 cutter master
The self-locking device of transmission case 1 and balanced weight 9, tension sensor 2 are installed on balanced weight 9 and connect appropriate portion on chain or wirerope
Position, when 4 stress of wirerope is more than setting value, tension sensor 2 issues electric signal, this signal introduces the emergency stop of machine tool controller
It controls in program, while acoustic-optic alarm can be added.
The present invention realizes the direct protection that chain or wirerope 4 are broken by tension sensor 2, the auxiliary dress directly protected
It sets and controls component and acoustic-optic alarm including relay etc..
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 present invention is using tension suffered by wirerope in each suspension unit of tension sensor real-time monitoring, under normal circumstances,
Multiple suspension units will not break down simultaneously, when individual suspension units break down when, 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 according to
The variation of each wirerope or chain tension can judge whether there is balanced weight falling risk, when part or all of steel wire rope tension
When transfiniting, 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 hold tightly it is self-locking.
Also, it in the case where abnormal do not work occur in self-locking device, multiple suspension units, is realized using mechanical buffer unit final
Protection, cause damages after preventing balanced weight from falling.The generation for effectively preventing balanced weight falling accident, ensure that equipment and people
The safety of member.
Present invention improves over balanced weight anti-falling self-locking devices, by the safety guard of Multiple Combination, eliminate existing
There is the disadvantage of technology, has prevented self-locking failure accidents caused by wearing because of self-locking device mechanical mechanism.
Compared with the existing technology, the configuration of the present invention is simple, convenient for checking, high reliablity, disposably investment and later maintenance
Expense is low.
