Problems solved by technology
Due to the complex and irregular structure of the counterweight, the clamping accuracy of the traditional counterweight is low, resulting in low machining accuracy of the counterweight installation hole and positioning hole. Therefore, the qualified rate of counterweight processing is very low and there are many waste products , the gearbox is easy to not be equipped with the counterweight, or the product is loose after the counterweight is assembled, causing noise, and the user's use effect is poor

The invention discloses a clamping tool and machining method of a balancing weight. The clamping tool can precisely position the balancing weight, machines an installation hole with the high precision, can achieve positioning through the installation hole, machines a positioning hole with the high precision, greatly improves the qualified productivity of the balancing weight and is good in using effect. The clamping tool comprises a base. A boss for supporting the weight increasing portion of the balancing weight is arranged at one end of the base. An adjustable apex for supporting the installation portion of the balancing weight is arranged at the other end of the base. Two stand columns are further arranged on the base, wherein one stand column is located on the outer side of the boss, and the other stand column is located on the outer side of the adjustable apex. The top of each stand column is provided with a pressing plate for compressing the balancing weight in the vertical direction. The machining method comprises the steps of casting and molding the balancing weight, conducting plunge milling of a key slot inside the installation hole of the balancing weight, conducting rough milling on the end face A and the end face B of the installation portion, conducting finish milling on the end face B of the balancing weight, reaming the installation hole, boring the installation hole, reaming the positioning hole and boring the positioning hole.
Description
technical field [0001] The invention relates to the technical field of automobile transmissions, in particular to a counterweight clamping tool and a processing method thereof. Background technique [0002] As one of the most important components in the automobile transmission system, the automobile transmission undertakes the important task of changing the torque and speed of the entire automobile and shifting gears of the automobile. With the continuous improvement of consumers' driving comfort, at present, some automobile gearboxes generally adopt the method of adding counterweights in order to improve the shift feel. Due to the complex and irregular structure of the counterweight, the clamping accuracy of the traditional counterweight is low, resulting in low machining accuracy of the counterweight installation hole and positioning hole. Therefore, the qualified rate of counterweight processing is very low and there are many waste products , The gearbox is easy to not b...
