Abstract
Provided is a rolling type small-sized orthopedic tool, which relates to a roll forming device and comprises a body. The body is provided with a roller (r1), a roller (r2) and a roller (R). The circle center of the roller (r1) and that of the roller (r2) are in the same line (A), and the circle center of the roller (R) is in the perpendicular bisector of the line (A). The roller (r1), the roller (r2) and the roller (R) are respectively provided with a shaft which is sleeved by a shaft sleeve fixed by a pivot pin. The roller (R) is a driving wheel, which can be manually driven or driven by other power modes like a motor. As a structure contacting with a workpiece, the roller can be in different shapes based on the surface shape of the workpiece. The final shape of the roller is determined by an overpressure amount based on the workpiece material. The utility model is advantageous in that the structure is simple, the volume is small and the weight is light; orthopedic work on the workpiece is precise; rollers in different shapes can be selected for processing based on the shape of the workpiece surface; the operation is convenient.
Description
Technical field
The utility model relates to rolling forming device, is specifically related to the small-sized orthopedic instrument of a kind of rolling-type.
Background technology
In recent years, along with the modern machines manufacturing industry develops to high accuracy, high-speed and high-power direction, requirement to material, machining accuracy and the workmanship of element part is also more and more higher, for this reason, having obtained increasingly extensive volume already in order to the rolling processing process that improves machine workpiece surface quality and its physical property of raising uses.In rolling and processing, people often utilize rolling tools to come workpiece is carried out orthopedic processing, and roll extrusion orthopedic equipment volume is big in the prior art, complex structure, and it is very inconvenient to operate, and machining accuracy is inaccuracy also, and stress is big, and instrument damages easily.
The utility model content
It is a kind of small-sized, light-duty, simple in structure that technical problem to be solved in the utility model is to provide, the small-sized orthopedic instrument of the rolling-type of handled easily
Technical problem to be solved in the utility model realizes by the following technical solutions,
The small-sized orthopedic instrument of a kind of rolling-type, comprise a body, in body, be provided with three r1 rollers, r2 roller and R roller, it is characterized in that: the center of circle of described r1 roller and r2 roller is on same straight line A, the center of circle of described R roller is on the perpendicular bisector of straight line A, be provided with axle in described r1 roller, r2 roller and the R roller, outer shaft sleeve has axle sleeve, fixes with pivot pin.
Described r1 roller, r2 roller and above the R roller pressing plate is installed.
Axle in the described R roller can move on the perpendicular bisector of straight line A.
Described R roller is a driving wheel, and power can be manually also can add other power modes such as driven by motor etc.
Described r1 roller, r2 roller and R roller can be selected different rollers according to the surface configuration of workpiece as the structure of contact workpiece, and the final typing of every kind of shape needs amount of over-pressurization, and what of amount of over-pressurization are decided according to workpiece material.The utility model can only be rectified r arc and straight line, can't integral correction to other unconventional arcs, but rectilinear workpiece can be curved predetermined r arc.
The utility model when work earlier fixedly the pivot pin of R roller take off, the R roller is extracted out, will treat that orthopedic workpiece is put into and contact with r1 roller, r2 roller, R roller reinstall is put the pivot pin of packing into.The axle of R roller can move on the online A perpendicular bisector, and the position of regulating shaft makes three rollers press workpiece to r arc shape or straight line to be rectified, and rotates the R roller and makes whole device orthopedic back and forth until ideal form on workpiece.
The beneficial effects of the utility model are: simple in structure, volume is little, light weight, and orthopedic accurately to workpiece, can select different rollers to process according to the surface of the work shape is different, easy to operate.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a profile of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the small-sized orthopedic instrument of a kind of rolling-type, comprise a body 5, in body 5, be provided with three r1 rollers 2, r2 roller 3 and R roller 1, the center of circle of r1 roller 2 and r2 roller 3 is on same straight line A4, the center of circle of R roller 1 is on the perpendicular bisector of straight line A4, be provided with axle 6 in r1 roller 2, r2 roller 3 and the R roller 1, the axle 6 outer axle sleeves 8 that are with, fix with pivot pin, r1 roller 2, r2 roller 3 and pressing plate 7 is installed above the R roller 1, the axle in the R roller 1 can move on the perpendicular bisector of straight line A.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
