When the present axle has the back dip, the size of front axle fore-and-aft direction is asymmetric, can not directly adopt the mode processing front axle's that turns around other end king-pin hole, so when reprocessing the other end after front axle one end processing is accomplished, the locating pad board need rotate 180, and it is wasted time and energy to dismantle the installation, has seriously influenced production efficiency.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art not enough, and provide a backing plate of shifting fast for machining, it sets present location backing plate to base and rotatable backing plate two parts, and the front axle of taking the caster angle turns around man-hour, only needs to rotate the backing plate of upper portion to labour saving and time saving improves production efficiency.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a quick conversion angle backing plate for machining, include the horizontally base in top, superpose in the backing plate at base top and connection the base with the bent axle round pin of backing plate, the bent axle round pin includes pivot and the locating pin that the axis becomes the contained angle, the pivot with the base rotates to be connected, the top of backing plate is the installation face of slope, the locating pin inserts the backing plate and with the installation face is perpendicular.
Further, the base is provided with the blind hole at the top, the pivot with blind hole clearance fit and but free rotation, the diameter of pivot is greater than the diameter of locating pin, contradict respectively at the both ends of pivot the bottom of blind hole with the bottom of backing plate.
Furthermore, the included angle between the rotating shaft and the positioning pin and the included angle between the mounting surface and the bottom surface of the backing plate are complementary angles.
Furthermore, the base plate is provided with a through hole of which the axis is perpendicular to the mounting surface, the positioning pin is in clearance fit with the through hole, the positioning pin protrudes out of the mounting surface, and the top end of the positioning pin is chamfered.
Further, the backing plate is fixed to the base through screws.
The utility model has the advantages that: the utility model provides a backing plate that makes a transition fast for machining, its include the horizontally base in top, superpose in the backing plate at base top and connection the base with the bent axle round pin of backing plate, the bent axle round pin includes pivot and the locating pin that the axis becomes the contained angle, the pivot with the base rotates to be connected, the top of backing plate is the installation face of slope, the locating pin inserts the backing plate and with the installation face is perpendicular. The utility model divides the prior positioning cushion plate into the base and the cushion plate, and the base and the cushion plate are connected through the crank pin, when the cushion plate is rotated for 180 degrees, the crank pin rotates along with the cushion plate, and the positioning pin is always vertical to the mounting surface; the utility model is simple in operation, laborsaving saving time has improved production efficiency.

Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1, the shim plate for quickly converting angles for machining according to the present embodiment includes a base 1 with a horizontal top, a shim plate 2 superposed on the top of the base 1, and a crankpin 3 connected to the base 1 and the shim plate 2, where the crankpin 3 includes a rotating shaft 31 and a positioning pin 32, the rotating shaft 31 is rotatably connected to the base 1, the top of the shim plate 2 is an inclined mounting surface 21, and the positioning pin 32 is inserted into the shim plate 2 and perpendicular to the mounting surface 21.
The utility model divides the prior positioning cushion plate into an upper part and a lower part, the base 1 of the lower part is fixed, and the cushion plate 2 of the upper part can horizontally rotate through the rotating shaft 31; when a transition is needed, the connecting screw between the backing plate 2 and the base 1 is taken down, because the rotating shaft 31 and the positioning pin 32 are not coaxial, the rotating shaft 31 is rotatably connected with the base 1, and the positioning pin 32 is inserted into the backing plate 2, when the backing plate 2 is pushed, the backing plate 2 horizontally rotates by taking the rotating shaft 31 as a shaft, and meanwhile, the positioning pin 32 rotates along with the backing plate 2, so that the positioning pin 32 and the mounting surface 21 are always kept vertical. The base plate 2 is light in weight and small in size, and is convenient to operate during transition, so that labor and time are saved, and the efficiency is improved.
The crank pin 3 of the present embodiment is an integrated structure, that is, the rotating shaft 31 and the positioning pin 32 are integrally manufactured or fixed together. The positioning pin 32 protrudes out of the mounting surface 21 and is used for positioning a workpiece, in order to prevent the positioning pin 32 from shaking when the workpiece is taken and placed, a blind hole 11 is formed in the top of the base 1, the rotating shaft 31 is in clearance fit with the blind hole 11 and can rotate freely, the diameter of the rotating shaft 31 is larger than that of the positioning pin 32, and two ends of the rotating shaft 31 respectively abut against the bottom of the blind hole 11 and the bottom of the backing plate 2; the backing plate 2 is provided with a through hole 22 with an axis perpendicular to the mounting surface 21, the positioning pin 32 is in clearance fit with the through hole 22, and the top end of the positioning pin 32 is chamfered.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
