Abstract
The utility model relates to a lathe center fixed frame with a protection effect on supporting claws, which comprises a lower frame body and an upper frame body. The lower frame body is hinged with the upper frame body; the supporting claws are relatively rotationally arranged on the lower frame body and the upper frame body; the front ends of the supporting claws are relatively rotationally provided with protection rolls; and the outer surfaces of the protection rolls are provided with grooves. According to the lathe center fixed frame, in the working process, the protection rolls are directly contacted with an object, the protection rolls cannot rotate, a machine tool can normally work and the object rotates when the abnormal condition is generated in the machining process to cause the excessively large torsion applied to the object, so that the protection rolls are driven to rotate and the supporting claws are not influenced. Therefore, the lathe center fixed frame has the protection effect on the supporting claws.
Description
Technical field
The utility model relates to a kind of lathe and uses fixture, relates in particular to a kind of lathe center fixation frame.
Background technology
The lathe center fixation frame that uses at present is when gripping objects, and bearing claw directly withstands on the object, and object is rigid friction with bearing claw in the process of rotation, is easy to damage bearing claw.
The utility model content
The utility model provides a kind of lathe center fixation frame that bearing claw is had protective effect to not enough.
The technical scheme that the utility model solves the problems of the technologies described above is following:
A kind of lathe center fixation frame comprises lower frame and upper frame, and lower frame and upper frame are for being articulated and connected; All be rotatably installed with bearing claw on lower frame and the upper frame relatively; It is characterized in that the bearing claw front end is rotatably installed with the protection roller relatively, the outer surface of protection roller has groove.
The beneficial effect of the utility model is:
The utility model in the course of the work, bearing claw withstand on the protection roller on, the protection roller directly contact with object; The protection roller can not rotate, but the lathe operate as normal, when occurring unusual condition in the process and cause object to receive excessive torsion; Object rotates; Thereby drive the rotation of protection roller, bearing claw is had no effect, so the utility model has protective effect to bearing claw.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of bearing claw among Fig. 1.
In the accompanying drawing:
1, lower frame; 2, bearing claw; 3, upper frame; 4, protection roller; 5, groove.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
A kind of lathe center fixation frame; Like Fig. 1, shown in Figure 2; Comprise lower frame 1 and upper frame 3, lower frame 1 and upper frame 3 all are rotatably installed with bearing claw 2 for being articulated and connected on lower frame 1 and the upper frame 3 relatively; Bearing claw 2 front ends are rotatably installed with protection roller 4 relatively, and the outer surface of protection roller 4 has groove 5.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
