[0021] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the relevant content and are not intended to limit the present disclosure. It should also be noted that, for ease of description, only the portions relevant to the present disclosure are shown in the accompanying drawings.

[0022] Figure 1 This is a schematic diagram of the structure of a quick ejection structure for a Swiss-type lathe back-axle product;

[0023] Figure 2 This is a cross-sectional view of the quick ejection structure of a Swiss-type lathe back-axle product;

[0024] Figure 3 This is a cross-sectional view of the adjustment seat of a Swiss-type lathe back-spindle product's rapid ejection structure;

[0025] like Figure 1-3 As shown, a quick ejection structure of a Swiss-type lathe back-axle product disclosed in the present invention may include: an ejection mechanism and an adjustment mechanism and other components;

[0026] like Figure 1-3 As shown, the ejection mechanism includes a main rod 1, a receiving groove 2, a secondary rod 3, a first centering sleeve 4, a positioning sleeve 5, a spring 6, a second centering sleeve 7, and a back shaft adapter 8;

[0027] The receiving groove 2 is opened inside the main rod 1, the auxiliary rod 3 is arranged in the receiving groove 2 and the end thereof extends to the outside of the main rod 1, the first centering sleeve 4 is slidably sleeved on one end of the main rod 1, the positioning sleeve 5 is fixed to the other end of the main rod 1, the spring 6 is sleeved on the main rod 1 and is located between the first centering sleeve 4 and the positioning sleeve 5, the second centering sleeve 7 is slidably sleeved on the end of the auxiliary rod 3 extending to the outside of the main rod 1, and the back shaft adapter 8 is installed on the outer surface of the second centering sleeve 7;

[0028] When in use, the device is installed inside the Swiss machine. When the product enters the back-shaft chuck of the Swiss machine, it squeezes the auxiliary rod 3. The auxiliary rod 3 drives the main rod 1 to move backward and retract through the adjustment mechanism. During the movement, the positioning sleeve 5 compresses the spring 6, and the back-shaft chuck is clamped at the same time. The back-shaft adapter 8 assists in clamping the back-shaft chuck. When the processing is completed, the back-shaft chuck is released to release the clamping of the product. Then the compressed spring 6 rebounds and drives the main rod 1 to restore its position, thereby driving the auxiliary rod 3 to eject the product. The operation is completed.

[0029] like Figure 1-3 As shown, the adjustment mechanism includes an adjustment hole 9, an adjustment seat 10, a cavity 11, a limit plate 12, a spring 13, and a clamp 14;

[0030] Multiple groups of adjustment holes 9 are evenly opened on the side of the main rod 1 and are connected to the receiving groove 2. The adjustment seat 10 is slidably set in the receiving groove 2 and is fixedly connected to the other end of the auxiliary rod 3. The cavity 11 is opened inside the adjustment seat 10. Two limit plates 12 are slidably set in the cavity 11. The spring 13 is set in the cavity 11 and is located between the two limit plates 12. Two clamps 14 are installed in the center of the sides of the two limit plates 12 and extend into the corresponding two adjustment holes 9;

[0031] When adjusting the overall length of the device, press the two clips 14 inward to disengage them from the adjusting holes 9. The two clips 14 that move inward compress the spring 13 through the limit plate 12 to release the fixation of the adjusting seat 10. Then rotate the auxiliary rod 3 to drive the adjusting seat 10 to rotate so that the two clips 14 rotate ninety degrees. At this time, let the inner wall of the storage groove 2 limit the two clips 14. Then press the auxiliary rod 3 inward to retract it into the storage groove 2. At the same time, the moving auxiliary rod 3 drives the adjusting seat 10 to move in the storage groove 2 to shorten the device length until the length is reached. After the predetermined length is reached, the auxiliary rod 3 is fine-tuned to drive the adjustment seat 10 to move so that the adjustment seat 10 is between the nearest set of adjustment holes 9. Then, the auxiliary rod 3 is rotated in the opposite direction to drive the adjustment seat 10 to rotate so that the two clamps 14 are aligned with the corresponding two adjustment holes 9. Without the squeezing of the inner wall, the compressed spring 13 rebounds to drive the two clamps 14 to insert into the aligned two adjustment holes 9. The main rod 1 and the auxiliary rod 3 are re-fixed to adjust the overall length of the device, so that the device can be adapted to various models of Swiss-type lathes, thereby increasing the practicality of the device.
