As national energy-saving and environment-friendly requirements are put forward, energy conservation and emission reduction in the automobile industry cannot be delayed even a moment. Lightweight of automobiles is one of the most effective means for energy conservation and emission reduction of the automobiles. The lightweight energy-saving effect of the wheel serving as a high-speed rotating unsprung mass is more remarkable than that of other parts, so the lightweight development of wheels has been an irresistible trend, wherein the wheels made of carbon fibers have been developed in the industry, and are different from conventional wheels in structure and machining mode.
The carbon fiber wheel is different from a conventional aluminum alloy wheel and a conventional steel wheel in structure, the wheel base body is made of carbon fibers, two high-performance aluminum alloy plates are arranged on the front side of the wheel and a flange, and the two aluminum alloy plates need to be bonded and pressed into the carbon fiber wheel body in interference fit during machining.
The present application is aimed at providing a composite wheel mounting device.
The present application adopts the following technical solution: an improved wheel mounting device comprises a base, a support, screws, springs I, sleeves, a flange positioning plate, sliding sleeves, springs II, movable pins, struts, a pressure cylinder, a connecting plate, guide posts, upper guide post flanges, a connector, lower guide post flanges and a pressure plate. The support is fixed on the base, the flange positioning plate is fixed on the support, the sliding sleeve is fixed on the flange positioning plate, the sleeve is fixed with the sliding sleeve, the strut slides in the sleeve and the movable pin, the strut passes through the sleeve and the sleeve is tightened together with the strut, and the spring I is put in the sleeve and the strut to adjust the vertical position of the strut. The movable pin moves up and down in the sliding sleeve, and the spring II is put in the movable pin and the sliding sleeve to adjust the vertical position of the movable pin. The upper guide post flanges are fixed on the base, and the guide posts pass through the upper guide post flanges and are fixed on the pressure plate together with the lower guide post flanges. The pressure cylinder and the connecting plate are fixed on the base, a pressure cylinder rod is connected with the connector, and the connector is fixed on the pressure plate.
In practical use, a lower flange plate is put on the upper surface of the movable pin, the upper surface of the lower flange plate is coated with a special bonding compound, then bolt holes of a carbon fiber wheel base body are aligned with the guide posts and the movable pin, the carbon fiber wheel base body is put on the lower flange plate, and the lower surface of an upper flange plate is coated with the special bonding compound and aligned with the bolt holes of the carbon fiber wheel base body.
When the upper flange plate is aligned with the bolt holes of the base body, the cylinder rod of the pressure cylinder moves down and drives the connector and the pressure plate to move, the guide posts move up and down in the upper guide post flanges and the lower guide post flanges to achieve a guiding effect, and the pressure plate moving down presses the upper flange plate to gradually press bosses at the bolt holes of the upper flange plate into the carbon fiber wheel base body; the strut begins moving down under pressure, then when the spring I is in a maximum pressed state, the head of the strut presses the movable pin and pushes the movable pin to move down, till the movable pin is separated from the lower flange plate, the lower flange plate contacts the flange positioning plate, and the lower flange plate at the moment has arrived at the limit position; the pressure plate continuously presses down, the bosses of the upper flange plate have been pressed into the carbon fiber wheel base body at the moment, then when the pressure reaches a certain value, the pressure value is kept for certain time, and bonding and interference fit between the carbon fiber wheel and the upper and lower flange plates are thus completed. Then, the pressure cylinder is depressurized, the pressure plate moves up to the original position, and the mounting procedure of the carbon fiber wheel is finally realized.
The improved wheel mounting device of the present application in use may meet the requirement for clamping when the carbon fiber wheel is machined, replaces artificial processing, and is ideal in effect, high in efficiency and safe and reliable in operation.
