Description
Technical field
The present invention relates to a kind of crossbeam operator guards, be specially adapted to vertical lathe.
Background technology
Vertical car is mainly used in processing short large-scale, the heavy workpiece of large, the length of diameter and the not easily workpiece of clamping on horizontal lathe, when tactical diameter meets, too heavy workpiece at sleeping carriage not easily clamping, due to dead weight, there is impact to machining accuracy, adopt vertical car to solve the problem.
In prior art, vertical car utilizes two elevating screws to hold in the palm rising and the decline of crossbeam, but due to the weight ratio of crossbeam comparatively large, so just there is huge potential safety hazard, the structure of the car elevating screw that therefore opposes is optimized design and just seems particularly necessary.
Summary of the invention
The present invention is directed to above-mentioned technical problem, provide a kind of crossbeam operator guards, it can realize safety in production, and lifting process is even, steadily, noise is little, reliable and stable.
According to technical scheme provided by the invention, a kind of crossbeam operator guards 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, 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 bolt on elevating screw and crossbeam are fixed, and by overarm brace, crossbeam are connected with elevating screw; The below of described elevator chamber is provided with the second spacer, the second plane bearing, the first ring flange, described second spacer, the second plane bearing, and the first ring flange is arranged on elevating screw, uses the second locking nut screwing; Be provided with the second ring flange, the 3rd plane bearing at the other end of elevating screw, support supporting elevation screw mandrel, support is fixed on lathe bed, fixes with the 4th plane bearing, the 3rd locking nut.
As a further improvement on the present invention, the other end of described worm screw connects external motor, can control the lifting of elevator chamber.
Compared with prior art, advantage is in the present invention: structure is simple, ingenious, reasonable, substantially increases the safety coefficient in production process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, elevator chamber 1, worm screw 2, first locking nut 3, worm gear 4, first plane bearing 5, first spacer 6, second spacer 7, second plane bearing 8, first ring flange 9, second locking nut 10, elevating screw 11, crossbeam 12, bolt 13, overarm brace 14, second ring flange 15, the 3rd plane bearing 16, the 4th plane bearing 17, the 3rd locking nut 18, support 19 and lathe bed 20 etc.
As shown in Figure 1; the present invention is a kind of crossbeam operator guards; comprise the body of lathe bed 20; be arranged on the elevator chamber 1 on lathe 20 lathe bed; be arranged on the worm gear 4 in elevator chamber 1 casing, worm screw 2 and elevating screw 11, described worm gear 4 is connected with worm screw 2, and worm gear 4 is arranged on elevating screw 11; overarm brace 14 on elevating screw 11 bolt 13 and crossbeam 12 are fixed, and prop up below elevating screw 11 with support 19.
Described elevator chamber 1 is arranged on above lathe bed 20, elevating screw 11 is arranged on elevator chamber 1 as shown in Figure 1, installed in the below of elevator chamber 1 is the second spacer 7 successively, second plane bearing 8, first ring flange 9, second spacer 7, second plane bearing 8, first ring flange 9 is arranged on elevating screw 11, then tightening with the second locking nut 10, which ensure that the installation site of elevating screw 11; First spacer 6, first plane bearing 5, worm gear 4 have been installed successively in elevator chamber 1, first spacer 6, first plane bearing 5, worm gear 4 are arranged on elevating screw 11, then tightening with the first locking nut 3 of precision, the effect that two ends are fixing can be reached like this, and utilize the first accurate locking nut 3 can be combined with elevating screw 11 tightr, Long-Time Service gets off, and crossbeam 12 also can not drive elevating screw 11 to glide, and this is the first step improved.Worm gear 4 connecting worm 2, connects external motor at the other end of worm screw 2, can control the lifting of elevator chamber 11 like this.Overarm brace 14 is screwed on elevating screw 11, with bolt 13, crossbeam 12 and overarm brace 14 is fixed together, 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 mandrel 11, support 19 is fixed on lathe bed 20.Be fixed on support with a plane bearing 17 and the 3rd locking nut 18 again, this structure has further ensured that elevating screw 11 glides, thus ensure that the safety in production process.
