The vertical positioning mechanism 20 includes a first positioning seat 21, a lower pressure cylinder 221 and a support member. The first positioning seat 21 is arranged on the workbench 10, and a first positioning column 201 for guiding the product 100 is provided thereon. The support member is arranged on the workbench 10 and is located beside the first positioning seat 21, specifically in front of the first positioning seat 21. A first support member 231 and a second support member 232 are respectively arranged on both sides of the square, the output end of the lower pressure cylinder 221 passes upward through the first positioning seat 21 and is provided with a lower pressure head 222, and the hydraulic rod of the lower pressure cylinder 221 is sleeved with a lower pressure plate 223 that can abut against the lower pressure head 222 and the product, the lower pressure head 222 drives the lower pressure plate 223 to vertically press the product 100 positioned on the first positioning column 201 on the first support member 231 and the second support member 232, the lateral positioning mechanism 30 includes a second positioning seat 31 and a lateral pressure member, the second positioning seat 31 is arranged on the workbench 10, and the product 100 is horizontally pressed on the second positioning seat 31 through the lateral pressure member. In the utility model, in order to improve the processing efficiency, the machining requirements of each surface that needs to be processed on the cutting machine head shell, that is, the product 100, can be completed on a set of tooling. Therefore, a vertical positioning mechanism 20 and a lateral positioning mechanism 30 are set to position the product 100 in the vertical direction and the horizontal direction, and there is an adjacent pair of vertical positioning mechanisms 20 and an adjacent pair of lateral positioning mechanisms 30, forming a four-station two-process machining mode, which is convenient for the cutter head to directly perform machining in two stations of another process after completing machining in two stations of one process.The specific processing process is as follows: two products 100 are respectively positioned vertically on two vertical positioning mechanisms 20, that is, a pair of first positioning columns 201 are respectively extended into the first holes 101 (blind holes) of the product 100 to achieve preliminary positioning of the product 100. At this time, the hydraulic rod of the lower pressure cylinder 221 and the lower pressure head 222 located thereon pass upward through the through hole on the product 100, and the lower pressure plate 223 is sleeved on the hydraulic rod or placed on the product 100. The lower pressure head 222 is driven by the lower pressure cylinder 221 to drive the lower pressure plate 223 to press the product 100, so that the product 100 is accurately positioned on the first support column 201 and abuts against the first The contoured surfaces 230 of the support member 231 and the second support member 232 are simultaneously or partially in contact with the contoured surface on the first positioning seat 21, thereby achieving stable vertical positioning and pressing of the product 100, and positioning the two products 100 horizontally on the two lateral positioning mechanisms 30, that is, positioning the product 100 on the second positioning seat 31, and stably positioning and pressing the product in the horizontal direction by the side pressure piece. After the product 100 is stably positioned as described above, machining is performed. After the processing of each process is completed, the processing of the new process can be achieved by replacing the product positioning on a different positioning mechanism, which can improve the processing efficiency.
