The first positioning block 102 is fixedly connected with the base 101. The cylinder body of the first cylinder 103 is fixedly connected with the base 101. The pressing block 104 is located above the camshaft 110, and the first positioning block 102 is located below the camshaft 110. The pressing block 104 is fixedly connected with the piston of the first cylinder 103. The second positioning block 105 is fixedly connected with the base 101. The limiting plate 106 is fixedly connected with the second positioning block 105. The limiting column 112 is fixedly connected with the limiting plate 106.

[0034] The first positioning block 102 comprises a first positioning groove 102a, and the second positioning block 105 comprises a second positioning groove 105a. The first positioning groove 102a and the second positioning groove 105a are used for radial positioning of the camshaft 110. The limiting plate 106 is located at one end of the second positioning block 105 and abuts against the camshaft 110, and the limiting plate 106 is used for axial positioning of the camshaft 110. The first positioning groove 102a is a V-shaped groove. The second positioning groove 105a is an arc-shaped groove.

[0035] The base 101 comprises a first limiting groove 101a, the first positioning block 102 comprises a first protrusion 102b, and the first protrusion 102b is inserted into the first limiting groove 101a. The base 101 comprises a second limiting groove 101b, the second positioning block 105 comprises a second protrusion 105b, and the second protrusion 105b is inserted into the second limiting groove 101b. The first positioning block 102 is fixedly connected with the base 101 by means of screws, and the second positioning block 105 is fixedly connected with the base 101 by means of screws. The first positioning block 102, the pressing block 104 and the first cylinder 103 are each provided with two groups. The camshaft 110 is placed in the first positioning groove 102a and the second positioning groove 105a, the radial direction of the camshaft 110 is positioned by the first positioning groove 102a and the second positioning groove 105a, one end of the camshaft 110 abuts against the limiting plate 106, and thus the axial direction of the camshaft 110 is positioned, so that the camshaft 110 is quickly positioned.

[0036] Workflow: Place the connecting shaft 108 on the three-jaw chuck 107 of the numerical control lathe, clamp the connecting shaft 108 through the three-jaw chuck 107, fix the connecting shaft 108 with the three-jaw chuck 107, fix the forming tool 109 with the connecting shaft 108, then place the camshaft 110 in the first positioning groove 102a and the second positioning groove 105a, position the camshaft 110 radially through the first positioning groove 102a and the second positioning groove 105a, abut one end of the camshaft 110 with the limiting plate 106, provide a limiting hole 110b on one end of the camshaft 110, insert the limiting column 112 into the limiting hole 110b, thereby positioning the camshaft 110 axially and ensuring the position of the eccentric oil groove 110a cut, thereby quickly completing the positioning of the camshaft 110. Then the piston of the first air cylinder 103 drives the pressing block 104 to fix the camshaft 110. Then the numerical control lathe drives the connecting shaft 108 and the forming tool 109 to rotate together, thereby machining the eccentric oil groove 110a of the camshaft 110 (the axis of the camshaft 110 is eccentric to the axis of the connecting shaft 108, so when the three-jaw chuck 107 rotates, the eccentric oil groove 110a can be machined), which is more convenient for the numerical control lathe to machine.
