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 machining device for the lower balance bearing hub of the present embodiment includes a bottom plate 1, the bottom plate 1 is provided with two parallel backing plates 2, the backing plate 2 is provided with a clearance hole 21, two ejector rod devices X3 are respectively provided at two ends of the backing plate 2, two ejector rod devices Y4 are respectively provided at the outer side of the backing plate 2, and two pressing plate devices Z5 are provided at the bottom plate 1 on the symmetric plane of the backing plate 2.
The structure of the ejector rod device X3 is the same as that of the ejector rod device Y4, the ejector rod device X3 and the ejector rod device Y4 both comprise a vertical plate 31 fixed on the bottom plate 1, a through hole 32 is formed in the vertical plate 31, a nut 33 coaxial with the through hole 32 is arranged on the vertical plate 31, and the nut 33 is sleeved with a screw 34 in threaded connection with the nut 33.
Each object has six degrees of freedom, and the casting of the lower balance bearing hub has no holes for positioning, so that the positioning and fixing of the lower balance bearing hub need to limit the degrees of freedom of the lower balance bearing hub from the direction of X, Y, Z; in production, the lower balance bearing hub is downward in arc, and two ends of the lower balance bearing hub are placed on the base plate 2; then adjusting the screw rods 34 of the four ejector rod devices X3, dividing the four ejector rod devices X3 into two groups, and respectively abutting against the lower balance bearing hub from two sides in the X direction so as to align the hole position to be processed of the lower balance bearing hub with the avoiding hole 21; then adjusting the screw rods 34 of the ejector rod devices Y4, and limiting the freedom degree of the lower balance bearing hub in the Y direction from two ends by two ejector rod devices Y4; the ejector rod device X3 and the ejector rod device Y4 also limit the rotation of the lower balance bearing hub around the Z axis at the same time; the pressure plate device Z5 is matched with the backing plate 2 to limit the lower balance bearing hub to move along the Z axis and rotate around the X axis and the Y axis. In summary, the ejector device X3, the ejector device Y4, the pressure plate device Z5 and the backing plate 2 limit six degrees of freedom of the lower balance bearing hub, and positioning and fixing are realized.
In this embodiment, the bottom plate 1 is provided with two sets of the above positioning and clamping devices, two corner cylinders 51 are arranged between the two sets of the positioning and clamping devices, or only one corner cylinder 51 is used, at this time, the pressing plate 52 is lengthened, and the middle part of the pressing plate 52 is fixed with a cylinder rod of the corner cylinder 51. According to the requirement, the bottom plate 1 can also be provided with more than two sets of the positioning and clamping devices, so that a plurality of workpieces can be clamped simultaneously.
