[0019] The preferred embodiment of the utility model is described in detail below in combination with the drawings, so that the advantages and characteristics of the utility model can be more easily understood by those skilled in the art, and the protection scope of the utility model can be more clearly and explicitly defined.

[0020] Please refer to Figure 1 and Figure 2As shown in the drawings, the embodiment of the present application provides a machine tool loading fixture, which comprises a base 1, a backing plate 2, a surrounding plate 3, an anti-falling bolt 4 and a fixing screw 5. The backing plate 2 is fixed on the base 1 by screws. The base 1 is used for being mounted on the fork arm of the hydraulic pallet truck 7, and the base 1 is fixed on the fork arm by tightening the fixing screw 5. In use, after the workpiece 6 is placed at the opening position on one side of the base 1, the surrounding plate 3 is mounted, and the anti-falling bolt 4 is inserted. The anti-falling bolt 4 is used for fixing the surrounding plate 3 and the base 1 to prevent the workpiece 6 from tilting.

[0021] As shown in the drawings, Figure 2 As shown in the drawings, the backing plate 2 is mounted on the base 1 to ensure that the backing plate 2 and the surrounding plate 3 are at the same height. The workpiece 6 is horizontally sectioned and adhered to the machine tool loading fixture by gravity, so that the workpiece 6 is in a horizontal posture in the machine tool loading fixture. The adhering surface of the workpiece 6 is higher than the gravity center of the workpiece 6, so that the workpiece 6 cannot be tilted. The anti-falling bolt 4 has a large cooperation gap, and the bolt is convenient to insert and take out. Specifically, the anti-falling bolt 4 is relatively long, and has a good anti-falling effect. For example, the length of the anti-falling bolt 4 is 8 to 12 times the thickness of the surrounding plate 3. The anti-falling bolt 4 can prevent the surrounding plate 3 from falling off, thereby achieving the purpose of preventing the workpiece 6 from tilting. The backing plate 2 and the surrounding plate 3 have a certain gap with the outer circle of the clamped workpiece 6, and this setting achieves the purpose of adjusting the posture of the workpiece 6 within 360° by hand.

[0022] As shown in the drawings, Figure 3 As shown in the drawings, the machine tool loading fixture is mounted on the fork arm of the hydraulic pallet truck 7. At this time, the workpiece 6 can be lifted, lowered and horizontally moved by the hydraulic pallet truck 7.

[0023] As shown in the drawings, Figure 4 As shown in the drawings, after the workpiece 6 enters the machine tool from the machine tool door and is sent to the upper side of the lower center of the machine tool, the posture of the workpiece 6 on the machine tool loading fixture can be manually adjusted, the center hole of the workpiece 6 is aligned with the lower center of the machine tool, and then the workpiece 6 is placed down. After the center hole of the workpiece 6 is matched with the lower center of the machine tool, the workpiece 6 is supported, the anti-falling bolt 4 is removed, and the surrounding plate 3 is removed. The upper center of the machine tool is lowered, the workpiece 6 is clamped, the hydraulic pallet truck 7 is moved out, and the loading is realized.

[0024] After the workpiece 6 is machined, the hydraulic pallet truck 7 is moved in, the base 1 is moved into the workpiece 6, the surrounding plate 3 is placed, and the anti-falling bolt 4 is inserted. The workpiece 6 is moved out of the machine tool to realize unloading.

[0025] Not limited to this, any changes or replacements not thought of through creative labor should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope defined in the claims.
