Abstract
The utility model provides a convenient, practical central rest comprising a main body, a handle disposed on the main body, a screw connected to the handle, a nut disposed on the screw, a spring retaining ring disposed on an end of the screw, and three supports. The main body is formed by modifying a three-claw self-centering chuck plate. The supports are formed by disposing a connection plate on the ends of a sliding seat of the three-claw self-centering chuck plate, after threads on the back of the three-claw self-centering chuck plate are milled. A circular holes parallel to an axis of the sliding seat is disposed in the connection plate. A bearing is fixedly disposed in the three-claw self-centering chuck plate by a pin shaft through a screwed hole in the pawl seat. The convenient practical central rest provided in the utility model has advantages of high working efficiency, and abilities of changing wastes into valuables, and saving resources.
Description
Technical field
The utility model relates to a kind of centre frame, relates in particular to a kind of convenient and practical centre frame of the stability of the rigidity that in mechanical processing process, is used for increasing workpiece and cutting.
Background technology
My company according to arts demand, must use centre frame as aiding support in carrying out mechanical roughing and accurately machined production process, increases the rigidity of workpiece and the stability of cutting.Yet in the long-term production, many three-jaw self-centering chucks have been scrapped in the past.Need centre frame based on this one side production; On the other hand; Storehouse has the situation of waste and old in a large number three-jaw self-centering chuck; That will be secondary development, cycling and reutilization to waste and old resource if can the three-jaw self-centering chuck of scrapping be transformed into centre frame, will practice thrift substantial contribution for enterprise.
Summary of the invention
The inventor finds that in the daily course of work machining needs centre frame and the three-jaw self-centering chuck of scrapping is in a large number arranged; Through the design and the transformation of the way, the utility model technical problem to be solved provides a kind ofly changes system into centre frame simple in structure, convenient and practical, that efficient is high with three-jaw self-centering chuck.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is the check ring that the structure of this convenient and practical centre frame comprises the handle on body and the body, the screw rod that is connected with handle, the nut on the screw rod, screw rod end; Three supportings; Said body is formed by three-jaw self-centering chuck structural reform system, removes the tapping of holing on the cylindrical circumference of the screw rod present position on the chuck body of centre bulge at car, on chuck body T-slot position, establishes the screw that is used to install pressing plate and hold-down bolt; Establish bearing in the chuck body bottom, chuck body is connected with bearing through bolt; Said supporting is to establish connecting plate in the slide end of the three-jaw self-centering chuck that mills the back screw thread; Connecting plate is provided with the circular hole of center and slide parallel axes, set firmly on the three-jaw self-centering chuck pawl seat one by bearing pin through the fixing bearing of the screwed hole on the pawl seat.
Loosening in order to prevent bearing pin, on the screw thread on the said pawl seat, smear screw thread fastening glue.
In order to improve positioning accuracy, can establish a triangular groove at said rest base according to the lathe face.
The utility model adopts the improved centre frame of technique scheme, has following beneficial effect:
⒈ has realized the utilization again of waste and old material through to three-jaw self-centering chuck transformation reprocessing, turns waste into wealth, and has practiced thrift resource.
The centre frame of the ⒉ transformation of the way adopts roller wheel bearing, utilizes the surface and the surface of the work friction of roller, and does not produce surperficial relative motion, can realize high-speed cutting.
Three supportings of ⒊ adopt T shape screw rod to drive high efficiency.
The centre frame of the ⒋ transformation of the way is simple in structure, is easy to the transformation of the way.
Description of drawings
Fig. 1 representes the structural representation of a kind of convenient and practical centre frame of the utility model;
In Fig. 2 presentation graphs 2 along the structural representation of A-A direction.
The specific embodiment
Specify below in conjunction with the structure of accompanying drawing a kind of convenient and practical centre frame of the utility model.
Referring to Fig. 1; Fig. 2; The structure of a kind of convenient and practical centre frame of the utility model comprises body and three supportings; Wherein body is to be formed by 9 transformations of the way of three-jaw self-centering chuck body, and three supportings are to be changed a social system by the claw slide 6 of three-jaw self-centering chuck to form, at the screw rod 10 of going back jug 7 on the body, be connected with handle 7, the nut 8 on the screw rod 10, the check ring 12 of screw rod 10 ends.For body; Remove the tapping of holing on the cylindrical circumference of screw rod 10 present positions on the chuck body 9 of centre bulge at car; On the T-slot position of chuck body 9, establish 6 screws that are used to install pressing plate 5 and hold-down bolt 4, establish bearing 16 in chuck body 9 bottoms, bearing 16 can be made according to the lathe center is high; In order to improve positioning accuracy; Can establish a triangular groove in bearing 16 bottoms according to the lathe face, chuck body 9 links together through 4 bolts and bearing 16, and the bevel gear hole can be used in the turnbuckle hole on the chuck body 9.For three supportings; Claw slide 6 ends at the three-jaw self-centering chuck that mills the back screw thread are welded to connect plate 11; Connecting plate 11 is provided with the circular hole of center and claw slide 6 parallel axes; Set firmly on the claw slide 6 of three-jaw self-centering chuck one by bearing pin 1 through the fixing bearing 2 of the screwed hole on the claw slide 6 and pad 3, loosening in order to prevent bearing pin 1, on the screw thread on the claw slide 6, smear screw thread fastening glue.Improved 3 supportings are installed on the chuck body 9, and T shape screw rod 10 end installation shaft are rotated T shape screw rod 10 and are guaranteed that the motion of claw slide is smooth with check ring 12, and centre frame is just changed a social system and accomplished like this.
The utility model utilizes the T shape guide rail of three claws on the chuck body 9 to do the rail plate of three supportings of centre frame, rotates through screw rod 10, drives radially sliding of claw slide 6, thereby realizes the purpose of holding workpieces.During use; After pad 14 through briquetting 17 and turnbuckle 15, turnbuckle 15 ends and nut 13 are fixed on lathe bed with centre frame, workpiece is sent in the air spider, under the workpiece rotation status; Rotate earlier and after bottom two screw rods 10 makes bearing claw bearing 2 evenly touch the work mounting s face nut 8 of screw rod 10 is tightened; And, regulate upper support pawl position again with 15 lockings of the turnbuckle of bearing 16, the locking of suitable back gets final product.
The utility model is on probation through changing a social system, and effect is fine, and is not only simple in structure, convenient and practical, efficient is high, and realized the utilization again of waste and old resource, for enterprise has practiced thrift production cost.
