The cross beam protection structure is characterized in that a worm gear, a worm and a lifting lead screw are arranged inside the body of the lifting box, the worm gear is connected with the worm and is installed on the lifting lead screw, a cross beam support is fastened on the lifting lead screw, the cross beam support on the lifting lead screw is fixed with a cross beam, the cross beam is connected with the lifting lead screw through the cross beam support, a second spacer bush, a second surface bearing and a first flange plate are installed below the lifting box and are tightened with second locking nuts, a second flange plate and a third surface bearing are installed at the other end of the lifting lead screw, and the support is fixed on the lathe bed body and is fixed through a fourth surface bearing and a third locking nut. Compared with the prior art, the cross beam protection structure has the advantages that the structure is simple, ingenious and reasonable, and the security coefficient in the production process is greatly improved.
Description
Technical field
The utility model relates to a kind of crossbeam protection structure, is specially adapted to vertical lathe.
Background technology
Vertical car is mainly used in processing that diameter is large, length is short is large-scale, heavy workpiece and be difficult for the workpiece of clamping on horizontal lathe, in the satisfied situation of tactical diameter, too heavy workpiece is difficult for clamping at sleeping carriage, due to dead weight, machining accuracy is had to impact, adopt vertical car to address the above problem.
In prior art, rising and decline that vertical car utilizes two elevating screws holding in the palm crossbeam, but because the weight ratio of crossbeam is larger, so just exist huge potential safety hazard, the structure of the car elevating screw that therefore opposes is optimized design and just seems particularly necessary.
Utility model content
The utility model, for above-mentioned technical problem, provides a kind of crossbeam protection structure, and it can realize safety in production, and lifting process evenly, steadily, and noise is little, reliable and stable.
The technical scheme providing according to the utility model, a kind of crossbeam protection structure comprises the body of lathe bed, elevator chamber, and described elevator chamber is arranged on the body of lathe bed, and feature is: also comprise worm screw, worm gear, elevating screw, crossbeam, overarm brace and support; Described worm gear, worm screw and elevating screw are arranged in elevator chamber casing; Described worm gear is connected with worm screw, the first spacer, the first plane bearing, worm gear are arranged on elevating screw one end, use the first locking nut screwing, overarm brace is fastened on elevating screw, overarm brace on elevating screw is fixed with bolt and crossbeam, by overarm brace, crossbeam is connected with elevating screw; The below of described elevator chamber is provided with the second spacer, the second plane bearing, and the first ring flange, described the second spacer, the second plane bearing, the first ring flange is arranged on elevating screw, uses the second locking nut screwing; The other end at elevating screw is provided with the second ring flange, the 3rd plane bearing, stent support elevating screw, and support is fixed on lathe bed, and Yong Siping City spherical bearing, the 3rd locking nut are fixed.
As further improvement of the utility model, the other end of described worm screw 2 connects external motor, can control the lifting of elevator chamber.
Compared with prior art, advantage is the utility model: simple in structure, ingenious, reasonable, greatly improved the safety coefficient in production process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, elevator chamber 1, worm screw 2, the first locking nut 3, worm gear 4, the first plane bearing 5, the first spacer 6, the second spacer 7, the second plane bearing 8, the first ring flange 9, the second locking nut 10, elevating screw 11, crossbeam 12, bolt 13, overarm brace 14, the second ring flange 15, the 3rd plane bearing 16, Siping City's spherical bearing 17, the 3rd locking nut 18, support 19 and lathe bed 20 etc.
As shown in Figure 1; the utility model is a kind of crossbeam protection structure; comprise the body of lathe bed 20; be arranged on the elevator chamber 1 on lathe 20 lathe beds; be arranged on worm gear 4, worm screw 2 and elevating screw 11 in elevator chamber 1 casing, described worm gear 4 is connected with worm screw 2, and worm gear 4 is arranged on elevating screw 11; overarm brace 14 use bolts 13 on elevating screw 11 are fixing with crossbeam 12, below elevating screw 11, with support 19, prop up.
Described elevator chamber 1 is arranged on lathe bed 20 tops, elevating screw 11 is arranged on elevator chamber 1 as shown in Figure 1, below elevator chamber 1, having installed is the second spacer 7 successively, the second plane bearing 8, the first ring flange 9, the second spacers 7, the second plane bearing 8, the first ring flange 9 is arranged on elevating screw 11, then with the second locking nut 10, is tightening, and has guaranteed like this installation site of elevating screw 11; The first spacer 6, the first plane bearing 5, worm gear 4 have been installed successively in elevator chamber 1, the first spacer 6, the first plane bearing 5, worm gear 4 are arranged on elevating screw 11, then with the first accurate locking nut 3, tightening, can reach so the fixing effect in two ends, and utilize tightr that the first accurate locking nut 3 can be with elevating screw 11 combinations, use for a long time, crossbeam 12 can not drive elevating screw 11 to glide yet, and this is the improved first step.Worm gear 4 connecting worms 2, connect external motor at the other end of worm screw 2, can control like this lifting of elevator chamber 11.Overarm brace 14 is screwed on elevating screw 11, with bolt 13, crossbeam 12 and overarm brace 14 is fixed together, and by overarm brace 14, crossbeam 12 is connected with elevating screw 11 like this.At the other end of elevating screw 11, install the second ring flange 15 and the 3rd plane bearing 16, as shown in Figure 1, then use support 19 supporting elevation screw mandrels 11, support 19 is fixed on lathe bed 20.With a plane bearing 17 and the 3rd locking nut 18, be fixed on support, this structure has further ensured that elevating screw 11 glides, thereby has guaranteed the safety in production process again.
