A pneumatic collet 2 is mounted on the lathe spindle 1, and a detection component is provided inside the pneumatic collet 2. The detection component comprises:

[0028] T-shaped rod 4, the outer wall of the rear section of the T-shaped rod 4 is clamped and fixed inside the pneumatic jacket 2, the rear section hole 41, the middle hole 42 and the front section hole 43 are opened inside the T-shaped rod 4, and the rear end surface of the T-shaped rod 4 is installed with a base 5;

[0029] The telescopic tip 6 is arranged inside the T-shaped plug rod 4. A docking port 62 and a water channel 63 are opened inside the telescopic tip 6. The docking port 62 and the water channel 63 inside the telescopic tip 6 are used to connect to the water inlet pipe 9 and guide the water flow into the inner cavity of the shaft product 12 to detect the state of the oil hole. A spring 13 is fixedly connected between the rear end of the telescopic tip 6 and the front end of the base 5. The spring 13 acts as a buffer and assists in fixing the telescopic tip 6, thereby increasing the stability and flexibility of the device.

[0030] A water inlet pipe 9 is provided inside the telescopic top 6, through which water from an external source can be introduced into the water channel 63 of the telescopic top 6;

[0031] The external water pipe 10 is arranged behind the lathe spindle 1.

[0032] The lathe tailstock center 3 is installed on the horizontally movable Z axis of the lathe. A shaft rod product 12 is provided between the opposite side ends of the lathe tailstock center 3 and the telescopic center 6, and an oil hole 121 is provided on the shaft rod product 12.

[0033] The rear hole 41 is connected to the middle hole 42, and the middle hole 42 is connected to the front hole 43. A drill jig 7 is inserted into the front hole 43 to provide accurate positioning for the shaft product 12. The interior of the drill jig 7 is hollow and used to install the shaft product 12. The outer wall of the T-shaped plug 4 at the front section is penetrated by multiple bolts 8. The drill jig 7 is fixedly installed in the front hole 43 by the bolts 8. The drill jig 7 is firmly fixed to the T-shaped plug 4 by the bolts 8 to prevent the drill jig 7 from loosening or shifting during processing and testing. It is also convenient to replace the drill jig to adapt to shaft products of different specifications. It has strong adaptability and improves the versatility of the device.

[0034] The docking port 62 is connected to the water channel 63, and the front port of the water channel 63 is connected to the inner cavity of the shaft product 12. The outer wall of the telescopic top 6 is located in the middle section and is provided with a boss 61. The boss 61 in the middle section limits the sliding of the telescopic top 6 in the T-shaped plug 4. The outer wall of the telescopic top 6 at the rear section is slidably arranged inside the rear section hole 41, and the outer wall of the telescopic top 6 at the front section is slidably arranged inside the middle hole 42.

[0035] The front end of the water inlet pipe 9 is inserted into the interior of the docking port 62 , and the rear end of the water inlet pipe 9 passes through the pneumatic jacket 2 and the lathe spindle 1 in sequence and extends backward.

[0036] The rear end of the external water pipe 10 is connected to a hose 102, which is used to introduce external water source, and the hose 102 has a certain flexibility and can bend with the movement of the lathe spindle without affecting the normal transportation of the water source. The front end of the external water pipe 10 is rotatably connected to a rotary joint 101, and the rotary joint 101 allows the water inlet pipe 9 to maintain a stable connection with the external water pipe 10 when rotating with the lathe spindle 1, avoiding pipe entanglement or twisting. The front end of the rotary joint 101 is fixedly connected to the rear end of the water inlet pipe 9 through a flange. Two pipe clamps 11 are provided on the outer wall of the external water pipe 10, and the two pipe clamps 11 are connected by a screw nut. The outer surfaces of the two pipe clamps 11 are fixedly connected to a bracket 111, and the bracket 111 is installed on the surface of the lathe. The cooperation of the pipe clamp 11 and the bracket 111 can prevent the external water pipe 10 from shaking or shifting during operation.

[0037] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0038] When in use, first, install the drill jig 7 in the front hole 43 of the T-shaped plug rod 4 through the bolt 8, then insert the T-shaped plug rod 4 into the pneumatic jacket 2 and clamp it. At this time, the water inlet pipe 9 passes through the pneumatic jacket 2 and the lathe spindle 1 and comes to the rear of the lathe spindle 1, and then connect the water inlet pipe 9 and the external water pipe 10. After that, install the shaft product 12 in the drill jig 7, then start the horizontal movement of the lathe Z axis, fix the shaft product 12 with the lathe tailstock center 3, run the lathe to process the oil outlet hole 121, and after the processing is completed, pass the external water pipe 10 and the water inlet pipe 9 into the telescopic center 6 Water is injected into the water channel 63 at the top, and the water flows into the inner cavity of the shaft product 12 through the water channel 63. If the oil hole 121 on the shaft product 12 has been completely drilled, water will flow out of the oil hole 121 smoothly. At this time, the degree of patency of the oil hole 121 can be judged by observing the water flow. If the water flows smoothly, it means that the oil hole 121 is not blocked and the drilling is in good condition. On the contrary, if no water flows out of the oil hole 121 or the water flow is very small, then there may be a problem that the oil hole 121 has not been drilled or is blocked, so that the problem of whether the oil hole 121 on the shaft product 12 is drilled can be detected.
