Abstract
An inner flow tube positioner for rolling ball guide screw rod cooling, wherein, an inner flow tube is arranged in a hollow guide screw rod; a flow groove is formed between the outer side of the inner flow tube and the inner side of the guide screw; a hollow support element is ringed on the free end of the inner flow tube which is in the guide screw rod to support the inner flow tube for keeping straight, the inner flow tube can not be deformed, and the width of the flow grooves in every position can be kept same.
Description
Technical field
The utility model relates to a kind of transmission device, and it is average to relate in particular to a kind of cooling effect, improves the working life of inner flow tube, and makes the inner flow tube positioning device of the ball driving screw cooling usefulness of inner flow tube keeping parallelism in driving screw.
Background technique
Work mechanism is often with the parts of ball driving screw as the straight line transmission feeding, and the mechanical friction that produces between transmission feeding because of the ball driving screw produces heat energy, for guaranteeing that the ball driving screw can be because of the heat effects precision that is produced, the ball driving screw is provided with cooling unit.As shown in Figure 4, one supporting base 51 in order to location driving screw 40 is to fasten in board 50, supporting base 51 is a hollow shape, the inboard is provided with bearing 52 and adorns this driving screw 40 1 ends in order to pivot, supporting base 51 is that the lock dress is fixed a hollow shape pedestal 53 1 ends in the exterior edge face, pedestal 53 another opposite end screw lock one fixed bolts 54 make and fasten an inner flow tube 45 in the fixed bolt 54.This inner flow tube 45 is to run through the driving screw 40 that is hollow shape, keeping inner flow tube 45 is hanging shape at driving screw 40, form chute 42 between inner flow tube 45 outer side walls and driving screw 40 inboards, inner flow tube 45 is a hanging shape away from an end of fixed bolt 54, pour in the inner flow tube 45 with cooling liquid, flow out and to flow into chute 42 behind the inner flow tube 45 and provide cooling action driving screw 40.Yet there are the following problems in the inner flow tube design of this cooling unit;
Because driving screw length is very long, inner flow tube length also should be elongate tube mutually, is put in the driving screw but inner flow tube is outstanding, so caliber is little, only at one end for fixed bolt is fixed on the pedestal, the other end presents unsupported hanging shape to longilineal inner flow tube, makes inner flow tube be the suspention shape.And the weight of cooling liquid after pouring into can be aggravated inner flow tube at driving screw toe in state, not only cause the chute width inequality of inner flow tube between initial and end end and driving screw inboard, cause flow velocity to change and cause the fast place of flow velocity to bring cooling effectiveness not good, in addition, inner flow tube is easy deformation also, reduces working life.
The model utility content
In order to overcome the above-mentioned shortcoming that existing spin driving screw inner flow tube exists, the utility model provides a kind of inner flow tube positioning device of ball driving screw cooling usefulness, it makes the chute width between inner flow tube outer tube and driving screw inboard average, cooling effect is average, improve the working life of inner flow tube, and make inner flow tube keeping parallelism in driving screw.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of inner flow tube positioning device of ball driving screw cooling usefulness, it is characterized in that, it is that an inner flow tube is set in hollowed lead screws, form chute between the inner flow tube outside and the driving screw inboard, described inner flow tube has two ends, one end is to be arranged in the driving screw, and this end has a supporter in arranged outside, to support inner flow tube keeping parallelism in driving screw.
The inner flow tube positioning device of aforesaid ball driving screw cooling usefulness, wherein supporter is a hollow and annular.
The utlity model has following advantage:
1. mainly be the inner flow tube at elongated condition, the free end outside in stretching into driving screw is provided with a hollow shape supporter, supports inner flow tube in driving screw keeping parallelism shape, flat by supporter, can not scratch bending deformation easily, improves working life.
2. inner flow tube keeping parallelism, then between inner flow tube and the driving screw, chute width along axial formation every bit position is suitable, the state that ad initio can keep small tolerance to tail, guarantee the stability of cooling liquid flow velocity in chute, and then average to the contact cooling action maintenance of each position of driving screw, the working life of improving driving screw relatively.
3. the utility model is provided with the supporter of hollow shape, and form is simple, and assembling fast, and is with low cost and popularize enforcement easily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an exploded perspective schematic representation of the present utility model.
Fig. 2 is the partial sectional view that the utility model is incorporated into the ball driving screw.
Fig. 3 is that inner flow tube one end of the present utility model is the partial sectional view of stationary state.
Fig. 4 is the assembled sectional view that existing driving screw disposes cooling unit.
The number in the figure explanation:
10 inner flow tubes, 11 closed ends
12 outages
20 supporters
30 valve plugs
40 driving screws, 42 chutes
Pipe in 45
50 boards, 51 supporting bases
52 bearings, 53 pedestals
54 fixed bolts
Embodiment
See also Fig. 1, shown in Figure 2, the grown form of the utility model cooling unit is prior art as described above, technical characteristics of the present utility model, be that the inner flow tube 10 that is suspended in the driving screw 40 is effectively located, wherein, the support Fixed Design of inner flow tube 10 1 ends is shown in Fig. 3 left side, still on pedestal 53, be not rotary state by fixed bolt 54 lockings, next as Fig. 1, shown in Figure 2, the free end of inner flow tube 10 in penetrating driving screw 40, form chute 42 spaces between inner flow tube 10 outsides and driving screw 40 inboards, this inner flow tube 10 is to form closed end 11 at free end, and inner flow tube 10 is being to wear knot one hollow shape supporter 20 in the outside with drive fit form slightly near closed end 11 positions.This supporter 20 also can be the tubular of an end for sealing, the outside of supporter 20 be and driving screw 40 madial walls between be little drive fit and can not slide easily, fill up the space of this section chute 42, inner flow tube 10 is provided with several outages 12 at a sidewall of adjacent supporter 20 positions.In addition, the valve plug 30 of adorning a leakproof is filled in adjacent inner flow tube 10 positions in the driving screw 40.
Whereby, the utility model is when implementing, cooling liquid is sent into by inner flow tube 10 head ends (as shown in Figure 3), and cooling liquid flows in the inner flow tube 10 and the outage 12 that arrives flows out in the chute 42, is touched driving screw 40 madial walls and is played cooling action by the cooling liquid of chute 42; Because 20 of the supporters of the utility model setting are held in the free end that inner flow tube 10 stretches into driving screw 40, keep inner flow tube 10 parallel with driving screw 40, reduce inner flow tube 10 curved possibility of inclining greatly, guarantee that chute 42 interior cooling liquid speeds stablize.
