The four-shaft gear grinding machine of the invention is operated, a worker firstly takes down a screwing nut and a backing plate, then the top end of a threaded rod passes through a central hole on a rigid circular saw blade, then the rigid circular saw blade is fixed through the backing plate and the screwing nut, a first motor is electrified, the first motor drives a first transmission shaft to rotate, the first transmission shaft drives a grinding wheel to rotate, then a first cylinder controls a first telescopic rod to move upwards, the first telescopic rod drives a placing plate and the rigid circular saw blade to move upwards, the chamfer of the rigid circular saw blade can be ground through the grinding wheel, a second motor is electrified according to the processing requirements of the rigid circular saw blades with different radiuses, the second motor drives a second transmission shaft to rotate, the second transmission shaft can respectively rotate in a rotating groove and a rotating hole, and further a fixing plate can move leftwards or rightwards under the action of a front limiting rod and a rear limiting rod, the second motor can rotate forwards and backwards, so that the position of the grinding wheel in the horizontal direction can be adjusted according to the requirements of rigid circular saw blades with different radiuses, and the use limitation is reduced; when the grinding wheel needs to be installed, a worker firstly slides the grinding wheel into the installation groove along the front side wall in the installation groove, then the front ends of two groups of first fixing pins extend into the two groups of first clamping grooves, then the second telescopic rods are controlled to move backwards through the second air cylinders, so that the two groups of second fixing pins respectively extend into the two groups of second clamping grooves, the grinding wheel can be installed, when the grinding wheel needs to be disassembled, the second telescopic rods are controlled to move forwards through the second air cylinders, the front parts of the first clamping plates extend into the connection grooves, so that the two groups of second fixing pins respectively extend out of the two groups of second clamping grooves, the grinding wheel can be disassembled, the operation is labor-saving, and the use convenience is improved; the connecting rod and the mounting rod can fix the first motor, so that the use reliability is improved; the four groups of universal wheels can facilitate the movement of the device by workers, thereby improving the use flexibility; the pull ring can save more labor when workers move the box body, and the use convenience is improved; the support can fix the second motor, so that the use stability is improved; the reinforcing rod can support and fix the second cylinder, so that the use reliability is improved; the working personnel can observe the processing condition in the working cavity through the transparent plate, so that the use controllability is improved; the multiple groups of heat dissipation holes can dissipate heat of the second motor, and use safety is improved.

The first motor, the second motor, the first air cylinder, the second air cylinder and the four groups of universal wheels used by the four-shaft gear grinding machine are purchased from the market, and only need to be installed and used according to the specification.

In the four-shaft gear grinding machine, the installation mode, the connection mode or the arrangement mode of all the components are common mechanical modes, and the specific structures, models and coefficient indexes of all the components are self-contained technologies, so that the four-shaft gear grinding machine can be implemented as long as the beneficial effects of the four-shaft gear grinding machine can be achieved, and further description is omitted.

In the four-shaft gear grinding machine of the present invention, unless otherwise specified, the terms "upper, lower, left, right, front, rear, inner, outer, and vertical and horizontal" and the like are included in the terms and the terms only represent the orientation of the terms in the normal use state, or be a trivial term understood by those skilled in the art, and should not be considered as limiting the term, at the same time, the numerical terms "first," "second," and "third," etc. do not denote any particular quantity or order, but rather are used to distinguish one from another, furthermore, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements, but also includes other elements not expressly listed or inherent to such process, method, article, or apparatus.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
