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 for a balancing weight. By the adoption of the clamping tool, the balancing weight can be positioned accurately, a high-precision installation hole is machined, then a high-precision positioning hole can be machined through positioning of the installation hole, the qualified production rate of the balancing weight is increased, and the use effect is good. The clamping tool comprises a base. A boss used for supporting a weight increment part of the balancing weight is arranged at one end of the base. An adjustable tip which is used for supporting an installation part of the balancing weight is arranged at the other end of the base. Two stand columns are further arranged on the base. One stand column is located on the outer side of the boss. The other stand column is located on the outer side of the adjustable tip. Pressing plates used for tightly pressing the balancing weight in the vertical direction are arranged on the tops of the stand columns respectively. The machining method comprises the steps that the balancing weigh is formed through casting, a milling key is inserted in a balancing weight installation hole, and the end face A and the end face B of the installation part are roughly milled; the end face B of the balancing weight is finely milled; and the installation hole is reamed and bored; the positioning hole is reamed and bored.
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...
