detailed description

Example

The wheel hub positioning six-jaw clamping fixture of the utility model includes: positioning pin holes and positioning pins (16 inches-22 inches), six T-slots, one center hole and four assembly holes. (1) Locating pin holes: according to the different sizes of the wheels, draw 16 inches, 17 inches, 18 inches, 19 inches, 20 inches, 21 inches, 22 inches on the board, a total of 7 circles, and they are distributed on the circumference 2 There are two positioning holes, but too many positioning pins will cause repeated movement of the positioning pins, inconvenient to find the positioning pins, etc., and reduce the clamping efficiency. Therefore, according to the size, the positioning pins are divided into 4 groups, 16-17 inches is a group, 18-19 inches is a group, 20-21 inches is a group, 22 inches is a group, and each group shares 2 positioning Pins are used for positioning when the hub is clamped. (2) Center hole: A hole with a diameter of 250mm is opened in the middle of the plate. This hole is used to cooperate with another utility model of the company's tightening sleeve, so as to fix the wheel hub installation disc part and effectively prevent the deformation of the spoke part. . (3) Six T-slots: With the center hole as the center, 6 T-slots pointing to the center of the circle are evenly distributed around. The angle between each two T-slots is 60 degrees, which can be effective Improve the accuracy of clamping and prevent the unbalanced force caused by uneven clamping during the clamping process, thus ensuring that the rim part during the milling process will not be deformed due to shrinkage and deformation caused by the milling window. (4) 4 assembly holes: this assembly hole matches the T-slot spacing in the clamping table on the corresponding milling equipment, and can be directly locked by screws. Therefore, the coordination stability of the six-claw plate for positioning the wheel hub and the equipment is improved.

Take a wheel hub with a specification of 17*7.5 as an example, the diameter is 17 inch wheels, and the tire width is 7.5 inches. The clamping steps before milling are as follows:

(1) Place the wheel hub positioning six-claw plate on the milling machine;

(2) Choose bolts on the 4 corners to fasten on the milling machine workbench;

(3) Put the positioning pin into the 17-inch positioning hole;

(4) Put the wheel hub on the wheel hub positioning six-claw plate, and place the outer edge of the wheel rim against the positioning pin;

(5) Put the splint in the 6 T-slots, clamp the raised part of the outer edge of the rim, and fix the bolts firmly.

Example 2:

Take the wheel hub with a specification of 21*9.5 as an example, the diameter is 21 inch wheels, and the tire width is 9.5 inches. The clamping steps before milling are as follows:

(1) Place the wheel hub positioning six-claw plate on the milling machine;

(2) Choose bolts on the 4 corners to fasten on the milling machine workbench;

(3) Put the positioning pin into the 19-inch positioning hole;

(4) Put the wheel hub on the wheel hub positioning six-claw plate, and place the outer edge of the wheel rim against the positioning pin;
