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. 1-3, the double-shaft positioning fixture for finish milling of the inner side of a steering knuckle fork in this embodiment includes a base 1, two shaft hole seats 2 are respectively fixed on the left and right sides of the base 1, half shafts 3 are inserted into the shaft hole seats 2, the half shafts 3 on the two sides are coaxial, a journal 31 abutting against the steering knuckle is arranged at the front end of each half shaft 3, a baffle 4 abutting against the inner side of one fork of the steering knuckle is arranged between the two shaft hole seats 2, an L-shaped seat plate 5 with one side extending forward is arranged at the rear part of the base 1, and the baffle 4 is fixed to the L-shaped seat plate 5; and a pressing device 6 for pressing the steering knuckle shaft is arranged on the upper surface of the L-shaped seat plate 5.
The utility model discloses the structure science, easy operation, in the production, put suitable position to the knuckle earlier, then both sides semi-axis 3 impels and inserts the fork shaft hole of knuckle to the centre, one of them semi-axis 3 the journal 31 is contradicted the knuckle and is made its fork medial surface and hug closely baffle 4 starts corner cylinder 63 makes clamp plate 62 is pressed the knuckle axle from the top on the supporting station 61. And the milling cutter horizontally processes the forked inner side surface on the other side of the steering knuckle from outside to inside in the direction perpendicular to the half shaft 3, when the processing is finished, the corner cylinder 63 is loosened, the half shaft 3 is withdrawn, the steering knuckle is turned over by 180 degrees, the clamping is carried out again, and the forked inner side surface on the other side is processed. The processing mode can ensure the vertical precision of the inner side surface and the fork-shaped shaft hole to the maximum extent.
The shaft hole seat 2 is provided with a plurality of positioning shaft holes 21 which are arranged up and down, and any two corresponding positioning shaft holes 21 of the shaft hole seat 2 on two sides are coaxial. So as to meet the processing of the inner side surfaces of the steering yoke fork with different structures.
The shaft hole seat 2 is fixed with a shaft hole sleeve 22 inserted into the positioning shaft hole 21, and the half shaft 3 is inserted into the shaft hole sleeve 22. The diameters of fork-shaped shaft holes of different steering knuckles are different, and by adopting the shaft hole sleeve 22, a plurality of shaft hole sleeves 22 with different diameters can be matched by only one set of clamp, so that the steering knuckles with different shaft hole diameters can be positioned.
The half shaft 3 may have a large diameter at the front end or a large diameter at the rear end, and in this case, the diameter at the rear end is large, that is, the diameter of the portion of the half shaft 3 that fits into the shaft hole sleeve 22 is larger than the diameter of the portion that fits into the spindle hole, so that the half shaft 3 is inserted into the shaft hole sleeve 22 from the outside.
The corner position of the corner cylinder 63 is 90 degrees, the pressing plate 62 is fixed at the top end of the cylinder rod of the corner cylinder 63, the first cushion block 64 and the second cushion block 65 which support the inner bearing position and the outer bearing position of the steering knuckle are connected with the supporting table 61 through bolts, and different steering knuckles can adopt different cushion block matching.
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.
