Problems solved by technology
Turn 1° or 0.5° at 360° angle to measure the corresponding pole diameter. Mechanical dividing head is used for low accuracy requirements. Optical dividing head is used for high-precision measurement. The price of high-precision optical dividing head is very high.
[0004] The conjugated cam is a double-linked cam, which requires the rollers to be in any transmission position, and the two rollers can mesh with the cam without clearance, which is difficult to achieve

The invention discloses a conjugate cam theoretical profile testing device. The device comprises a cam angle positioning rotator, a cam clamping part, a main cam profile measuring part and a return cam and roller clearance measuring part. The conjugate cam theoretical profile testing device has the beneficial effects that the device not only can be used for accurately measuring the theoretical profile of a conjugate cam but also is simple and convenient to operate and is relatively low in manufacturing cost; a cam angle positioning controller is used instead of a costly high-precision optical dividing head and program and automatic control is also utilized for correction to ensure high resolution, so that precise positioning is achieved and the angular displacement of the cam is displayed, the angle positioning recurrence rate is 0.2 degree and the precision is equivalent to that of the high-precision optical dividing head; the cam angle positioning controller is convenient to use; a first roller clings to the profile of a main cam under the action of a pressure spring; the polar radius of the main cam is measured by a dial indicator; conjugate cam profile detection also comprises function detection; and when the main cam is completely meshed with rollers, the clearance between a return cam and a second roller is detected by a thickness gauge.
Description
technical field [0001] The invention belongs to the field of looms, and in particular relates to a conjugate cam theoretical profile testing device. Background technique [0002] At present, the positive conjugate cam mechanism has been widely used on high-speed looms. The positive conjugate cam mechanism adopts a closed shape. When the warp opening is at the highest position and the lowest position, the working parts are under the greatest force. The high pair fails for a short time. Under the action of inertial force, the cam roller breaks away from the cam profile, and from the moment the roller breaks away to the cam profile re-contact, the driven rod produces jumping and strong vibration. Therefore, the manufacturing and measuring requirements of the form-closed positive opening conjugate cam are extremely high, which is a difficult point in the manufacture of the cam mechanism. [0003] The cam profile is not a combination of straight line and circle, the profile curv...
