[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] like Figure 1As shown, the internal spline repeated processing error-proofing device G comprises an air pressure head 1, an air pressure gauge 2, an air tightness detector 3 and a control box 41.

[0023] The air pressure head 1 is connected to one end of the barometer 2 through a first air pipe 51, the other end of the barometer 2 is connected to the air tightness detector 3 through a second air pipe 52, and the air tightness detector 3 is connected to an air source through a third air pipe 53, for example, the air source of the machine tool 4. Of course, other external air sources can also be used.

[0024] The airtightness detector 3 is connected to the control box 41 via a control harness 54 .

[0025] A first warning light 42 and a second warning light 43 are provided on the top of the control box 41. For example, the first warning light 42 is red, and the second warning light 43 is green.

[0026] It should be noted that a speaker or other alarm device may also be provided on the control box 41 .

[0027] like Figure 2 As shown, the air pressure head 1 comprises a base 11, on which a cylindrical large shaft 13 is disposed, and on the top of the large shaft 13 a cylindrical small shaft 16 is disposed. The outer diameter of the small shaft 16 is smaller than that of the large shaft 13.

[0028] The side wall of the large rod 13 is provided with an air supply connection screw hole 14 , and the top end surface of the large rod 13 is provided with four linear grooves 15 , which are distributed in a “well” shape.

[0029] The outer wall of the small rod 16 is provided with four evenly distributed small holes 17 , and the top end surface of the small rod 16 is provided with a central hole 18 , which passes through the air supply connection screw hole 14 of the large rod 13 .

[0030] It should be noted that the base 11 is provided with a plurality of base screw holes 12, so that the air pressure head 1 can be fixed to the workbench of the equipment by bolts.

[0031] In addition, an air pressure sensor is provided in the air tightness detector 3, and a main control chip is provided in the control box 41. The air pressure sensor detects the change of the air pressure flowing through the air tightness detector 3, thereby judging the stability of the air flow flowing through, and feeds back the signal to the main control chip. This will be further explained later.

[0032] The working mode of the internal spline repeated processing error prevention device G is described below.

[0033] Step S1: Press the start button, the gas from the gas source of the machine tool 4 is transmitted from the third gas pipe 53 to the air tightness detector 3, then transmitted to the barometer 2 through the second gas pipe 52, and finally transmitted to the air pressure head 1 through the first gas pipe 51. Then, the gas is released outward from the four small holes 17 of the small shaft 16 of the air pressure head 1;

[0034] Step S2: Figure 3 As shown, the workpiece P is placed on the air pressure head 1 so that the M surface of the workpiece P is aligned with the N surface of the air pressure head 1, and the gas is stably released outward through the groove 15 on the air pressure head 1;

[0035] Step S3: If the workpiece P has been processed with internal splines, since the number of spline teeth is odd, one of the four small holes 17 will leak faster, and the air pressure will be unstable. The airtightness detector 3 will feed back a signal to the control box 41, and the first prompt light 42 will light up red and alarm. If the workpiece P is not processed, the gas output is stable, the air pressure is stable, the second prompt light 43 will light up green, and the machine tool robot will take the workpiece P away for processing.

[0036] The internal spline repeated processing error-proofing device is easy to operate, reduces the risk of repeated processing of workpieces, and reduces scrap costs. The internal spline repeated processing error-proofing device can quickly and efficiently perform air pressure detection on the inner hole of the workpiece to confirm whether the internal spline of the workpiece has been processed, ensuring that the internal spline processing of the part is one-time, so as to better control product quality, improve product quality stability, and improve production efficiency.

[0037] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope defined in the claims.
