Abstract
The invention relates to a counter-weight structure, in particular to a counter-weight structure of a cross beam, and specifically provides a counter-weight structure of a cross beam on a vertical lathe. According to the technical scheme, the counter-weight structure of the cross beam comprises a lathe body, a headstock located at the top end of the lathe body and the cross beam located on the lathe. A balancing weight which can ascend and descend inside the lathe body is arranged inside the lathe body. A balancing bracket is arranged inside the headstock and provided with a chain. The chain is supported on the balancing bracket. One end of the chain is connected and fixed to the cross beam. The other end of the chain is connected and fixed to the balancing weight. The counter-weight structure of the cross beam is compact in structure, safe and reliable, and can effectively solve the problem that the excessive weight of the overall lathe causes a drop in movement accuracy and improve the machining accuracy and efficiency of the lathe.

Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of counter weight construction of crossbeam is provided, its compact conformation, can effectively solve lathe because the overweight kinematic accuracy causing of crossbeam entirety declines, and improves lathe machining accuracy and efficiency, safe and reliable.
According to technical scheme provided by the invention, the counter weight construction of described crossbeam, comprises lathe bed, is positioned at the headstock on lathe bed top and is positioned at the crossbeam on lathe bed; In described lathe bed, be provided with can elevating movement in described lathe bed balance weight, in headstock, be provided with balance bracket, balance bracket is provided with chain, and described chain is supported on balance bracket, and one end and the crossbeam of chain are connected and fixed, the other end and the balance weight of chain are connected and fixed.
On described balance bracket, symmetrical roller is set, described roller can rotate on balance bracket, and chain passes through roller contact rear support on balance bracket.
Described balance bracket is fixed in headstock by the first set bolt.Described roller is arranged on balance bracket by rolling wheel installing shaft.
The both ends of described chain are all connected with balance weight and crossbeam respectively by chain joint, and chain is connected and fixed by taper pin and chain joint.The bottom of described lathe bed is provided with base, and base is positioned at the below of crossbeam.
Advantage of the present invention: balance weight is set in lathe bed, balance weight is connected with crossbeam by chain, chain is installed and is supported on by roller on balance bracket, when crossbeam weight is excessive, the gravitation energy of balance weight and the weight of crossbeam are carried out certain balance, reduce the effect of weight of crossbeam, compact conformation, lathe be can effectively solve because the overweight kinematic accuracy causing of crossbeam entirety declines, lathe machining accuracy and efficiency improved, safe and reliable.

The specific embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As depicted in figs. 1 and 2: in order to avoid the overweight work problem that affects vertical lathe because of crossbeam 4, the present invention includes lathe bed 2, be positioned at the headstock 1 on lathe bed 2 tops and be positioned at the crossbeam 4 on lathe bed 2; In described lathe bed 2, being provided with can be at the balance weight 13 of described lathe bed 2 interior elevating movements, in headstock 1, be provided with balance bracket 6, balance bracket 6 is provided with chain 7, described chain 7 is supported on balance bracket 6, and one end of chain 7 and crossbeam 4 are connected and fixed, the other end of chain 7 and balance weight 13 are connected and fixed.
Particularly, the weight ratio crossbeam 4 of described balance weight 13 lightweight, or approach the weight of crossbeam 4, by the effect of balance weight 13 and chain 7, can effectively reduce because of the overweight kinematic accuracy that affects lathe bed 2 of crossbeam 4.In lathe bed 2, be hollow structure, balance weight 13 can be in the interior oscilaltion campaign of lathe bed 2.The bottom of described lathe bed 2 is provided with base 3, and base 3 is positioned at the below of crossbeam 4.Balance weight 13 and crossbeam 4 lay respectively at the both sides of balance bracket 6, and all straight down, after the effect by chain 7 and roller 5, balance weight 13 can reduce the impact of crossbeam 4 weight on lathe bed 2 kinematic accuracies to the gravity direction of the gravity direction of balance weight 13 and crossbeam 4.
In the embodiment of the present invention, for the stability that can guarantee that crossbeam 4 and balance weight 13 move, two balance brackets 6 are set headstock 1 is interior, a chain 7 are set on each balance bracket 6, by two chains 7 respectively connection functions on balance weight 13 and crossbeam 4.Wherein, on each balance bracket 6, symmetrical roller 5 is set, described roller 5 can rotate on balance bracket 6, and chain 7 contacts rear support on balance bracket 6 by roller 5.Roller 5 on balance bracket 6 is respectively adjacent to crossbeam 4 or balance weight 13, in roller 5, is provided with draw-in groove, and described draw-in groove allows chain 7 to set, and chain 7 is realized in the draw-in groove of roller 5 and the contacting and the support of balance bracket 6 to chain 7 of roller 5 by being embedded in.Described balance bracket 6 is fixed in headstock 1 by the first set bolt 8, at the bottom of two balance brackets 6 are all fixed on the case of headstock 1 by the first set bolt 8.
Described roller 5 is arranged on balance bracket 6 by rolling wheel installing shaft 9.Rolling wheel installing shaft 9 is fixing with balance bracket 6 by the second set bolt 10, and roller 5 can make roller 5 do gyration on balance bracket 6 after being arranged on balance bracket 6 by rolling wheel installing shaft 9.
The both ends of described chain 7 are all connected with balance weight 13 and crossbeam 4 respectively by chain joint 11, and chain 7 is connected and fixed by taper pin 12 and chain joint 11.On balance weight 13 and crossbeam 4, all have screwed hole, one end of chain joint 11 can be fastenedly connected with balance weight 13 and crossbeam 4 respectively by screw thread, the other end of chain joint 11 is realized and being fixedly connected with of chain 7 by taper pin 12, guarantees the connection reliability of chain 7 and balance weight 13 and crossbeam 4.
The present invention is at the interior balance weight 13 that arranges of lathe bed 2, balance weight 13 is connected with crossbeam 4 by chain 7, chain 7 is installed and is supported on balance bracket 6 by roller 5, when crossbeam 4 weight are when excessive, the weight of the gravitation energy of balance weight 13 and crossbeam 4 is carried out certain balance, reduces the effect of weight of crossbeam 4, compact conformation, lathe be can effectively solve because the overweight kinematic accuracy causing of crossbeam entirety declines, lathe machining accuracy and efficiency improved, safe and reliable.
