[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a bushing inner hole through / out detection device, comprising: a base plate 1, a first guide rail 4, a second cylinder 12 and a product placement seat 13 mounted on the upper surface of the base plate 1, and a lower upright plate 15 mounted on the lower surface of the base plate 1;

[0023] The first guide rail 4 is slidably connected to the first sliding connecting plate 3 via a slider. The first cylinder connecting plate 2 is fixedly installed at one end of the first sliding connecting plate 3. The first cylinder connecting plate 2 is fixedly connected to the telescopic end of the second cylinder 12. The upper plate 5 is fixedly installed on the first sliding connecting plate 3. The first sliding connecting plate 3 is driven by the telescopic extension of the second cylinder 12 to drive the upper plate 5 to move linearly along the first guide rail 4.

[0024] The first cylinder 6 and the second guide rail 9 are installed on the side of the upper plate 5. The second guide rail 9 is slidably connected to the second sliding connecting plate 8 by a slider. The second cylinder connecting plate 7 and the first limiting plate 10 are fixedly connected to the second sliding connecting plate 8. The second cylinder connecting plate 7 is fixedly connected to the telescopic end of the first cylinder 6.

[0025] The first cylinder 6 extends and retracts to drive the second sliding connecting plate 8, which in turn drives the first limiting plate 10 to rise and fall along the second guide rail 9. The upper plate 5 also drives the first limiting plate 10 to move linearly along the first guide rail 4, so that the first limiting plate 10 can move closer to or further away from the product placement seat 13.

[0026] A sensor component 11 is installed on the side of the product placement seat 13 away from the first limiting plate 10. The upper sensor component 11 includes two sensors for detecting the position of the workpiece on the product placement seat 13.

[0027] A lower sensor component 16 is installed at the side edge of the lower plate 15. The lower sensor component 16 also includes two sensors, both of which sense the travel of the second limit plate 23.

[0028] A third cylinder connecting plate 20 is fixedly installed on the bottom side of the lower plate 15. A third cylinder 18 is fixedly installed on the third cylinder connecting plate 20. The telescopic end of the third cylinder 18 is fixedly connected to the second limiting plate 23.

[0029] A spring mounting base 21 is also fixedly installed on the third cylinder connecting plate 20. A spring 17 is installed inside the spring mounting base 21, and a go / no-go gauge 14 is inserted into the spring 17. The part of the go / no-go gauge 14 above the spring 17 passes through the limiting rod 22. The limiting rod 22 abuts against the lower part of the second limiting plate 23. The upper part of the go / no-go gauge 14 moves through the bottom plate 1 and the product placement seat 13. The lower end of the go / no-go gauge 14 passes through the spring mounting base 21 and the third cylinder connecting plate 20 and is fixedly connected to the moving part of the displacement sensor 19 installed at the lower end of the lower upright plate 15. When the third cylinder 18 drives the second limiting plate 23 to move upward, the spring 17 is released, and the go / no-go gauge 14 moves upward by pushing the limiting rod 22. Conversely, when the second limiting plate 23 is driven back by the third cylinder 18, the go / no-go gauge 14 moves downward by the limiting rod 22, and the spring 17 is compressed.

[0030] Working principle: When the product is placed on the product placement seat 13, if the middle hole of the product passes through the upper rod of the go / no-go gauge 14, one of the sensors in the upper sensor component 11 will sense the workpiece and send a signal to the PLC to proceed to the next process. If the middle hole of the product cannot pass through the upper rod of the go / no-go gauge 14, the position of the product will change due to the position of the go / no-go gauge 14. At this time, another sensor in the upper sensor component 11 will sense the workpiece, and the product will be unqualified. A signal will be sent to the PLC to determine the product as unqualified.

[0031] When the product is found to be qualified, the second cylinder 12 extends and moves the first limiting plate 10 directly above the product. The first cylinder 6 extends and presses the first limiting plate 10 onto the product to fix it in place.

[0032] The third cylinder 18 extends, causing the second limit plate 23 to move upward. At the same time, under the action of the spring 17, the limit rod 22 and the go / no-go gauge 14 both move upward, and the moving part of the displacement sensor 19 also moves upward. If the go / no-go gauge 14 cannot enter the inner hole of the product, the third cylinder 18 stops extending under the influence of the reaction force. At this time, one of the sensors in the lower sensor component 16 senses the second limit plate 23, and the product is qualified. If the go / no-go gauge 14 moves a certain distance and enters the inner hole of the product, the third cylinder 18 will continue to extend until it is fully extended. Then, the other sensor in the lower sensor component 16 will sense the second limit plate 23, and the product is unqualified.

[0033] After the test is completed, the third cylinder 18 retracts and drives the limit rod 22 to descend, the go / no-go gauge 14 retracts, the displacement sensor 19 retracts, the second cylinder 12 extends, and at the same time the first cylinder 6 retracts, driving the first limit plate 10 to retract. The entire system returns to the standby position, completing the measurement.

[0034] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
