[0025] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 3 :

[0026] A heat treatment processing device for a shaft body comprises a base 1, on which a plurality of through holes 10 are evenly distributed, on which a plurality of longitudinally arranged sliding columns 11 are fixed, on which a plurality of processing units 2 are slidably arranged through the sliding columns 11 above the base 1, the processing units 2 comprise a base plate 20 which is covered on the base 1, and on which a plurality of air holes 200 are opened, on which a plurality of sliding sleeves 21 which are sleeved on the sliding columns 11 are arranged, on which a plurality of upper end surfaces of the sliding sleeves 21 are abutted against a grid 22, and on which a storage grid 220 for the shaft body to be inserted is opened, and at the upper end of the grid 22 a partition frame 23 is provided, and at which a lower end surface of the partition frame 23 abuts against an upper end surface of the grid 22, and on which corresponding sliding holes 201 for sleeved on the sliding columns 11 are opened, the base plate 20, the grid 22 and the partition frame 23.

[0027] The specific usage is:

[0028] The base 1 is placed at the bottom, and the processing unit 2 is sleeved with the slide column 11 in turn. During the installation of the processing unit, the base plate 20 is used to abut the bottom of the shaft body. After the base plate 20 is placed, the grid is placed by raising it with the sleeve, and the storage grid on the grid is used to insert the shaft body. When the shaft body is placed, the bottom of the shaft body abuts against the upper end surface of the base plate 20. Since the shaft body is relatively long, the upper end of the shaft body extends out of the grid 22, and is raised by the partition frame 23, thereby isolating the upper end of the shaft body. The entire processing unit can reasonably conduct heat through the air holes 200 of the base plate 20, and at the same time, reasonable heat conduction is carried out on the side wall of the processing unit.

[0029] The through hole 10 opened on the base 1 can reasonably conduct heat during the heat treatment process. The length of the slide column 11 is greater than the height of the processing unit 2, and is used to place more processing units 2.

[0030] During the heat treatment process, not only the processing unit 2 on the machine needs to be heated, but the entire base can also be placed in the coolant by forklift or crane to cool it down, which can also greatly improve the processing efficiency.

[0031] Preferably, the grid 22 includes a plurality of parallel transverse metal wires 221 and longitudinal metal wires 222 with the same spacing, and the transverse metal wires 221 and longitudinal metal wires 222 are overlapped to form the storage grid 220 .

[0032] In the above structure, the storage grid 220 formed by interweaving the transverse metal wires 221 and the longitudinal metal wires 222 should be different in size according to the actual size of the shaft, or the grid 22 placed in each different processing unit should have different sizes to cope with shafts of different sizes.

[0033] Preferably, the partition frame 23 includes a partition frame surrounded by four groups of outer partition plates 230, and a plurality of parallel inner partition plates 231 are arranged in the partition frame.

[0034] Preferably, a plurality of plate holes 232 are formed on the outer partition plate 230 and the inner partition plate 231 .

[0035] In the above structure, both the outer partition plate 230 and the inner partition plate 231 are provided with plate holes 232, which facilitates improving the heat conduction effect during the heat treatment process.

[0036] Preferably, a limit stop ring 110 is formed on the slide column 11 , and the lower end surface of the limit stop ring 110 abuts against the upper end surface of the base 1 , and the upper end surface of the limit stop ring 110 abuts against the lower end surface of the base plate 20 .

[0037] The limiting retaining ring 110 can effectively elevate the processing unit and ensure the air permeability of the bottom.

[0038] Preferably, the cross-sections of the sliding post 11 and the sliding hole 201 are both circular. The circular design allows the sliding tongue to slide more smoothly.

[0039] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
