Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to fig. 1-4, the auxiliary support frame for long-axis workpieces comprises a support frame 1 with a top opening 1a, and a support plate 2 with a circular arc support surface 2a is arranged in the support frame 1 at the side of the top opening 1 a. The support bracket is mainly used for supporting the middle position of a shaft workpiece with a certain length at equal intervals, and the problem that the middle part of the shaft workpiece which is too long is bent due to gravity is avoided. The supporting function is that the supporting brackets are placed at the bottom of the middle part of the shaft workpiece at equal intervals and are supported at a certain height, so that the arc supporting surface 2a of the supporting plate 2 is attached to the bottom surface of the shaft workpiece to support, and the problem that the shaft workpiece with a certain length is easy to bend when being placed for a long time is solved.

Because the levelness of placing the axle type work piece has the error, the circular arc holding surface 2a of this backup pad 2 also has horizontal error, lead to circular arc holding surface 2a to appear the contained angle in the laminating with axle type work piece bottom surface, lead to binding face to reduce, the holding power descends to the side of circular arc holding surface 2a is with work piece bottom surface fish tail easily. Therefore, in order to avoid the problem, the two ends of the supporting plate 2 are rotatably connected to the side walls on the two sides of the supporting frame 1, so that when the arc supporting surface 2a is attached to the bottom surface of the workpiece, the arc supporting surface 2a can rotate to eliminate the horizontal error between the two, thereby achieving the effect of tightly attaching the two and realizing powerful supporting effect on the workpiece.

Under the action of the rotational support of the arc support surface 2a, as shown by the arrow in fig. 4, the support force of the support plate 2 for supporting the workpiece may be transmitted to one side of the support frame 1, and the other (left) side of the support plate may tilt, so that the support of the bottom surface of the support frame 1 may be unstable and may tilt, and therefore, in order to avoid this problem, a balancing device for the support frame 1 is disposed at the bottom of the support frame 1 and engaged with the support plate 2. The problem that the bottom surface of the support frame 1 is stressed unevenly and is prone to toppling is caused by the fact that the supporting force of the support plate 2 is deviated to one side of the support frame 1 through the balancing device.

Specifically, the balancing unit includes support frame 1 bottom is followed 2 length direction articulated balance plate 3 of backup pad, balance plate 3 with leave the equilibrium space of a take the altitude through articulated between the backup pad 2 in the equilibrium space and be located the both sides of this articulated department along 2 length direction of backup pad are all followed to the interval and are equipped with symmetrical balance spring 8. As shown in fig. 3, when the arc support surface 2a is attached to the bottom surface of the workpiece to bias the support plate 2 to one side of the support frame 1 with respect to the support frame 1, the support frame 1 is biased to one side by the support force, and the biased support force is vertically transmitted to one side of the balance plate 3 through the balance spring 8 of the corresponding side (indicated by an arrow in fig. 3), so that the balance plate 3 does not have the state that the one side is tilted, and the support plate 2 has a stable support force.

In order to facilitate the supporting operation of the supporting bracket suitable for workpieces with different placing heights, the outer sides of two ends of the balance plate 3 are symmetrically provided with lifting plates 4, and the inner sides of the lifting plates 4 are provided with guide rails 5 used for the balance plate 3 to slide up and down. The balance plate 3 slides up and down along the guide rail 5, so that the arc supporting surface 2a of the supporting plate 2 can be quickly attached to the bottom surface of the workpiece for supporting.

In order to fasten the position of the arc supporting surface 2a of the supporting plate 2, which is attached to and supported by the arc supporting surface, a reinforcing plate 6 is connected between the bottoms of the symmetrical lifting plates 4, and an adjusting screw 7 which is rotatably connected with the bottom of the balance plate 3 and used for lifting the balance plate 3 penetrates through the reinforcing plate 6. By rotating the adjusting screw 7, the balance plate 3 is slid up and down along the guide rail 5, and the arc support surface 2a of the support plate 2 is attached to the bottom surface of the workpiece.

The principle of the utility model is that: the supporting bracket is used for supporting shaft workpieces with certain lengths in an auxiliary mode, and the problem that the workpieces are easy to bend when placed for a long time is solved. The balancing device of the support bracket can ensure that the arc support surface of the support plate is effectively attached to the bottom surface of the workpiece, eliminate the horizontal error between the support bracket and the workpiece and provide powerful support effect.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
