Description

Technical Field

[0001] The utility model relates to the technical field of bolt screening, in particular to a bolt screening device. Background Art

[0002] A bolt is a mechanical part, a cylindrical threaded fastener that is matched with a nut. A type of fastener consisting of a head and a screw, which must be matched with a nut to fasten two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

[0003] At present, in the process of bolt production and manufacturing, bolts of different specifications are mixed together, which leads to the need to classify and screen these bolts. Due to the small size of bolts, accurate screening becomes more difficult. Because bolts of different specifications have similarities in size, length, shape, etc., the difficulty of screening is further increased. Therefore, it is difficult to separate and screen bolts of different specifications during screening. Therefore, a bolt screening device is proposed. Utility Model Content

[0031] The first support rod 2 and the second support rod 3 are both fixedly mounted on the top of the base 1, the vibrating loading seat 4 is located on the right side of the base 1, the vibration motor 5 is fixedly mounted inside the vibrating loading seat 4, and the feed rail 6 is fixedly mounted on the top of the first support rod 2 and the second support rod 3 and is located inside the vibrating loading seat 4, so that the bolt can be driven to move to the lower left through the vibration structure.

[0032] See also Figure 1-3 The guide mechanism includes a guide plate 12 fixedly mounted on the left outer wall of the feed rail 6, two first baffles 13 fixedly mounted on the top outer wall of the guide plate 12, two adjusting plates 14 rotatably mounted on the top outer wall of the guide plate 12, a connecting plate 15 fixedly mounted on the top outer wall of the adjusting plate 14, and a driving motor 16 fixedly mounted on the top outer wall of the first baffle 13. The first baffle 13 is rectangular, and the output shaft of the driving motor 16 is fixedly mounted on the top of the connecting plate 15. The distance between the bottom outer wall of the adjusting plate 14 and the top outer wall of the connecting plate 15 is the same as the height of the first baffle 13. The angle of the adjusting plate 14 can be changed by the action of the driving motor 16, so that the adjusting plate 14 guides bolts of different specifications in different directions.

[0033] A classification box 17 is movably mounted on the left outer wall of the guide plate 12. The guide plate 12, the first baffle plate 13, the adjustment plate 14, the connecting plate 15 and the drive motor 16 are all inclined from the upper right to the lower left. The height of the top of the guide plate 12 is the same as the height of the top of the classification box 17. The guide plate 12 and the feed rail 6 have the same inclination angle, which provides a certain sliding force on the bolts so that the bolts can quickly fall into the interior of the classification box 17.

[0034] See also Figure 1 and Figure 4 The guide mechanism also includes two second baffles 18 fixedly installed inside the classification box 17. The top of the second baffle 18 is higher than the top of the classification box 17. The two second baffles 18 divide the classification box 17 into three equal parts. The second baffles 18 improve the accuracy of screening.

[0035] See also Figure 1 The screening mechanism includes a distance detection sensor 8 fixedly mounted on the inner wall of the bottom of the feed rail 6, a mounting seat 9 fixedly mounted on the outer wall of the top of the base 1, an electric telescopic rod 10 fixedly mounted on the outer wall of the top of the mounting seat 9, and a limit plate 11 fixedly mounted on the telescopic axis of the electric telescopic rod 10. The distance detection sensor 8, the electric telescopic rod 10 and the limit plate 11 are all installed at an inclined angle and have the same inclination angle as the feed rail 6. The bolts of different lengths are measured by the screening mechanism and then guided and classified.

[0036] A feed trough 7 is provided at the top of the feed rail 6, and a slide hole 19 is provided at the bottom of the feed rail 6. The telescopic shaft and the limit plate 11 of the electric telescopic rod 10 are slidably connected inside the slide hole. Through the action of the electric telescopic rod 10 and the limit plate 11, the specifications of the bolts are detected one by one, which is convenient for subsequent classification.

[0037] In this embodiment, the model of the distance detection sensor 8 is VL53L0X, the distance detection sensor 8 is located on the left side of the electric telescopic rod 10, and the drive motor 16 is located on the upper left of the distance detection sensor 8. After the bolt is detected by the distance detection sensor 8, the drive motor 16 will start and drive the adjustment plate to rotate the adjustment direction. The distance detection sensor 8, the electric telescopic rod 10 and the drive motor 16 are electrically connected.

[0038] In this embodiment, a plurality of bolts are slidably connected to the top of the feed rail 6 , and the bolts are slidably connected to the inside of the feed trough 7 and are of matching sizes, and there is a certain distance between the plurality of bolts.

[0039] In this embodiment, the second baffle 18 divides the interior of the classification box 17 into areas, and can classify bolts of various specifications. At the same time, the second baffle 18 can also prevent the bolts that should fall into this area from falling into another area, thereby improving the quality of screening.

[0040] The working principle of the above embodiment is:

[0041] First, start the vibration motor 5 to drive the feed rail 6 to vibrate, and then place the bolts one by one in the feed trough 7 opened on the feed rail 6. At this time, the bolt will move from the upper right to the lower left. When the bolt passes the distance detection sensor 8, the distance detection sensor 8 detects the length of the bolt. At this time, the electric telescopic rod 10 will drive the limit plate 11 to move upward to prevent other bolts from sliding to the distance detection sensor 8. When the bolt falls onto the guide plate 12, the drive motor 16 is started at the same time to drive the connecting plate 15 to rotate a certain angle. At this time, according to the length specification of the bolt, the adjustment plate 14 will change the sliding direction of the bolt, and finally the bolt will fall into the classification box 17 and be located in the specified area. After the current bolt is detected, the electric telescopic rod 10 will drive the limit plate 11 to move downward to detect and screen the next bolt.
