[0025] Referring to Figures 1-3 As shown, as an embodiment of the present utility model, there is provided a lathe comprehensive inspection workpiece, including a hemispherical body 1, a first cylindrical body 2, a frustum, and a second cylindrical body 5 that are coaxially arranged and sequentially arranged. The diameter of the second cylindrical body 5 is greater than that of the first cylindrical body 2. A threaded structure 6 is provided on the circumferential side of the first cylindrical body 2 for inspecting the machining accuracy of the lathe encoder. An annular groove 7 is provided on the circumferential side of the second cylindrical body 5 for inspecting the accuracy of the gauge. The annular groove 7 is located on the side of the second cylindrical body 5 close to the frustum. The frustum is used to detect the linkage accuracy of the X-axis and Z-axis of the lathe, and the hemispherical body 1 is used to detect the overall stability of the machine tool. The lathe comprehensive inspection workpiece of the present utility model is suitable for machining inspections of three-jaw lathe series models, such as vertical lathes, horizontal lathes, etc. The lathe comprehensive inspection workpiece is machined by the milling cutter of the lathe, thereby realizing multiple different performance inspections of the lathe. The final processed product needs to be inspected for accuracy on a three-coordinate measuring instrument. This technical solution concentrates multiple performance inspections of the lathe on one comprehensive inspection workpiece, so that only one workpiece needs to be machined in the entire inspection project, and there is no need to repeatedly load and unload and replace the inspection workpiece, the operation is more concise and convenient, the processing efficiency is higher, and the inspection workpiece is a repetitive inspection workpiece and can be used multiple times. Next time during machining, only a tool setting operation (i.e., lowering the cutting layer of the milling cutter) is required, reducing the inspection cost.

[0026] In this embodiment, the surfaces of the hemisphere 1 and the frustum are smooth surfaces. By detecting the surface finish of the frustum, the linkage accuracy of the X-axis and Z-axis of the lathe can be detected. By detecting the surface finish of the hemisphere 1, the overall stability of the machine tool can be detected, further improving the detection accuracy.

[0027] In this embodiment, the frustum includes a first frustum 3 and a second frustum 4. The top diameter of the first frustum 3 is equal to the diameter of the first cylinder 2, the bottom diameter of the first frustum 3 is equal to the top diameter of the second cylinder 5, and the bottom diameter of the second frustum 4 is smaller than the diameter of the second cylinder 5. This setting enables the frustum to have circumferential sides with two different inclination gradients, thereby further improving the linkage detection accuracy of the X-axis and Z-axis of the lathe.

[0028] In this embodiment, the height range of the workpiece comprehensively detected by the lathe is 100 - 150 mm, the height range of the annular groove 7 is 5 - 15 mm, the diameter range of the second cylinder 5 is 60 - 80 mm, and the bottom diameter range of the first frustum 3 is 40 - 60 mm. Preferably, the height of the workpiece comprehensively detected by the lathe is 130 mm, the height of the annular groove 7 is 10 mm, the diameter of the second cylinder 5 is 70 mm, and the bottom diameter of the first frustum 3 is 50 mm. The distance between the annular groove 7 and the second cylinder 5 is 5 mm.

[0029] In summary, the workpiece for comprehensive detection in this embodiment has the following advantages:

[0030] 1. By concentrating multiple detection items on one workpiece for comprehensive detection, only one workpiece needs to be processed in the entire detection project, reducing the number of workpieces for processing and detection.

[0031] 2. Multiple performance detections can be completed through one processing, with concise and convenient operation, improving the processing efficiency.
