Embodiment Construction

[0013] Such as figure 1 Shown is a schematic diagram of the structure of the present invention. The present invention includes: a clamping device, a fixed base 5 , a slide block 6 and a conjugate cam 4 . The slide block 6 is provided with two small round wheels 7, 8, and the whole slide block 6 is located in the guide rail in the fixed base 5, and the fixed base 5 is provided with a conjugate cam 4, wherein the small round wheel 8 on the right side is connected with the The opposite side of abrasive belt 9 is in contact, the small round wheel 7 on the left side is in contact with conjugate cam 4, and the tightening device is connected with slide block 6.

[0014] The tightening device in the present invention can be a cylinder device, also can be a hydraulic transmission device or a spring device, as long as the slide block is tightened against the abrasive belt, it all belongs to the scope of the present invention.

[0015] Refer below figure 1 Describe in detail the worki...

Abstract

A conjugate wheel antifriction device used for grinding the camshaft conjugate abrasive band is belong to the grinding areas of the mechanical engineering. The inventions includes: device for tightening, fixed base, slider and conjugate cam. Two small round wheels are fixed on the slider, the slider is in the slide guide fixed on the base. The conjugate cam is fixed on the fixed base, thereinto the right small round wheel touches the inverse of the abrasive band and the left touches the conjugate cam. The device for tightening is connected with the slider. The right small round wheel gores the abrasive band tightly and keeps rolling with the abrasive band, the left small wheel keeps rolling with the cam. The device is simple and easy to manufacture, thereby reduces the friction of conjugate wheel, plays a friction of anti-friction and improves the useful life of the abrasive band of the grinder.

Description

technical field [0001] The invention relates to an anti-friction mechanism, in particular, a conjugate wheel anti-friction mechanism for camshaft conjugate abrasive belt grinding, which belongs to the field of grinding in mechanical engineering. Background technique [0002] In the processing and production of automobiles, the camshaft is a key part of the engine. The camshaft grinder is the key equipment for processing the camshaft of the automobile engine. Conjugate wheel abrasive belt grinding is currently a very effective method for machining camshafts. [0003] After searching the literature of the existing technology, it was found that the new CNC conjugate camshaft abrasive belt grinder developed by Shanghai Machine Tool Works Co., Ltd. has applied for 3 patents, namely: belt tensioning device for conjugate camshaft grinder (Patent No. 200420110629 ), a synchronous control system for a conjugate camshaft grinder (Patent No. 200420110630), and a conjugate wheel relea...
