The main feature of this type of grinding machine is that it can complete the cam processing efficiently and accurately.

For cams with complex shapes and high precision requirements, this all-round grinding can make the contour accuracy of the cam within ±0.01mm, which can better meet actual use needs.

[0023] 3.

The other group of slidingly mounted chucks 206 is rotatably mounted on one end of the piston rod of a first electric push rod 205. The first electric push rod 205 is fixedly mounted on the upper surface of the mounting frame 102, so that the chuck 206 can be pushed by the first electric push rod 205 to move closer to the other group of chucks 206, so that the cam can be clamped between the two groups of chucks 206.

[0041] A connecting rod 209 is fixedly installed on the other end of the chuck 206 rotatably installed in the connecting plate 204, and a push plate 208 is rotatably installed on one end of the connecting rod 209. The push plate 208 is fixedly installed on one end of the piston rod of the second electric push rod 207.

After the two sets of chucks 206 clamp the cam, the cam can be prevented from rotating when being ground.

[0042] The chuck 206 controlled by the second electric push rod 207 to rotate can be pushed by the full stroke of the second electric push rod 207 to perform a 180° rotation operation, and can perform a 180° flip operation on the cam clamped therebetween.

[0043] The first enclosure plates 201 are fixedly installed on the outer surfaces of the two groups of connecting plates 204, and the two groups of second enclosure plates 202 are rotatably installed between the two groups of first enclosure plates 201. The two groups of first enclosure plates 201 and the second enclosure plates 202 can enclose the clamped cam and can enclose the grinding debris.

[0044] Magnets 203 are provided on both sides of the first enclosure 201 and one end of the second enclosure 202, so that the two sets of second enclosures 202 can be flipped and attracted to one end of the magnets 203 on both sides of the first enclosure 201 to realize the assembly of the enclosure frame.

For cams with complex shapes and high precision requirements, this all-round grinding can make the contour accuracy of the cam within ±0.01mm, better meeting actual use requirements.

[0050] In summary: it is possible to flip the clamped cam 180°, thereby achieving all-round grinding of the cam, which ensures that the upper and lower halves of the cam can be accurately ground, avoiding the shape error that may be caused by grinding only one side. For cams with complex shapes and high precision requirements, this all-round grinding can make the cam profile accuracy within ±0.01mm, better meeting actual use needs.
