[0036] See Figure 1 and Figure 2 As shown, Figure 1 This is a structural schematic diagram of a bolt feeding device 100 provided in this application. Figure 2 This is a schematic diagram of the structure of push component 2 in this application.

[0037] This application provides a bolt feeding device 100, which includes a conveying component 1, a pushing component 2, and a driving component 3. The conveying component 1 includes a conveyor belt 11 for conveying bolts along a first direction F1 and a receiving groove 12 spaced apart from the conveyor belt 11 along the first direction F1. The receiving groove 12 has a slot located downstream of the conveyor belt 11 along a second direction F2, so that the bolts conveyed by the conveyor belt can fall into the receiving groove 12 through the slot. The sidewall of the receiving groove 12 has openings communicating with the receiving groove 12 on opposite sides along a third direction F3. The pushing component 2 includes a moving block 21 facing one of the openings. The driving component 3 is connected to the moving block 21 to drive the moving block 21 to move along the third direction F3 and push the bolt located in the receiving groove 12 out through the other opening by passing through the adjacent opening. The first direction F1, the second direction F2, and the third direction F3 intersect each other.

[0038] The bolt feeding device 100 provided in this application conveys bolts via a conveying assembly 1 and feeds bolts to a specific position onto a machine tool via a pushing assembly 2. Specifically, the conveying assembly 1 includes a conveyor belt 11 and a receiving groove 12. The receiving groove 12 is spaced apart from the conveyor belt 11 along a first direction F1 and has a slot facing the conveyor belt 11. Bolts conveyed by the conveyor belt 11 to the receiving groove 12 are conveyed into the receiving groove 12 through the slot. The sidewall of the receiving groove 12 has openings communicating with the receiving groove 12 on opposite sides along a third direction F3. The moving block 21 of the pushing assembly 2, driven by the driving assembly 3, can extend into the receiving groove 12 through one of the openings, push the bolt in the receiving groove 12 along the third direction F3, and push the bolt out through the other opening. It can be understood that the bolt feeding device 100 of this application mechanizes the bolt feeding process, saving manpower and resources.

[0039] See Figure 1 and Figure 2 As shown, the driving component 3 includes a pushing block 31 and a driving device 33. The pushing block 31 and the moving block 21 are arranged opposite each other along a third direction F3. The driving device 33 is connected to the pushing block 31 and is used to drive the pushing block 31 to move along a first direction F1, thereby driving the moving block 21 to move along a third direction F3. The pushing block 31 includes a pushing surface for pushing the moving block 21, and the pushing surface is set at acute angles to both the first direction F1 and the third direction F3. When the pushing block 31 pushes the moving block 21 to move along the third direction F3, the pushing surface of the pushing block 31 abuts against the moving block 21, and the pushing surface is set at acute angles to both the first direction F1 and the third direction F3. It can be understood that when the pushing block 31 moves along the first direction F1, it provides a component force towards the third direction F3 to the moving block 21 via the pushing surface, thereby driving the moving block 21 to move along the third direction F3.

[0040] See Figure 1 As shown, the conveying assembly 1 includes two side plates 14 respectively disposed on opposite sides of the conveyor belt 11 along the third direction F3. A receiving groove 12 is formed between the two side plates 14. Each side plate 14 is provided with an opening, that is, the opening on each side plate 14 faces the receiving groove 12 along the third direction F3, and the two openings communicate with the receiving groove 12 along the third direction F3. At least a portion of the moving block 21 passes through the opening on the adjacent side plate 14 along the third direction F3, so as to make the moving block 21 parallel to the longitudinal direction of the receiving groove 12 along the third direction F3, so that it can push the bolt along the third direction F3 under the push of the pushing block 31. The pushing component 2 also includes a return spring 22 located outside the receiving groove 12. The return spring 22 is arranged around the opening adjacent to the moving block 21 and is connected between the side plate 14 where the opening is located and the moving block 21. When the push block 31 pushes the moving block 21 away from the initial position and moves along the third direction F3 to push the bolt, the return spring 22 is in a compressed state, giving the moving block 21 a spring force away from the side plate 14. After the bolt is pushed out, that is, after the action of pushing out the bolt is completed, the push block 31 is withdrawn and gives the moving block 21 a pushing force along the third direction F3. At this time, the spring force given by the return spring 22 to the moving block 21 makes the moving block 21 return to the initial position and prepare for the next action of pushing the bolt.

[0041] See also Figure 1 and Figure 2As shown, the pushing component 2 includes a snap-fit ​​component 24, which includes a snap-fit ​​part 241 and a first abutment part 243 connected to each other. The snap-fit ​​part 241 is movably inserted into the side plate 14 adjacent to the moving block 21 along the first direction F1 and extends into the receiving groove 12, and snaps into the moving block 21. The first abutment part 243 is located outside the side plate 14. That is, when the moving block 21 is in the initial position, the snap-fit ​​part 241 snaps into the moving block 21, which plays a positioning role for the moving block 21 and prevents the moving block 21 from detaching from the opening on the side plate 14.

[0042] The snap-fit ​​assembly 24 also includes a second abutment portion 244 spaced apart from the first abutment portion 243 along the first direction F1. The drive assembly 3 is also connected to the second abutment portion 244 to drive the second abutment portion 244 to move along the first direction F1 toward the side closer to the first abutment portion 243, so that the second abutment portion 244 changes from being spaced apart from the first abutment portion 243 to abutting against the first abutment portion 243, so as to give the first abutment portion 243 a pushing force along the first direction F1, pushing the first abutment portion 243, and driving the snap-fit ​​portion 241 to disengage from the moving block 21. After the snap-fit ​​portion 241 disengages from the moving block 21, the moving block 21 can move along the third direction F3 under the push of the abutment portion, thereby pushing the bolt located in the receiving groove 12.

[0043] Continue reading Figure 2 As shown, a sliding portion is provided in the side plate 14 adjacent to the movable block 21, and the locking portion 241 is movably and slidably connected to the sliding portion along the first direction F1. It can be understood that the driving assembly 3 drives the second abutting portion to move along the first direction F1, thereby abutting and pushing the first abutting portion 243 on the locking portion 241 to move along the first direction F1, driving the locking portion 241 to move along the first direction F1 on the sliding portion to disengage from the movable block 21.

[0044] The locking assembly 24 also includes a limiting spring 242 extending along the first direction F1. The limiting spring 242 is connected to the locking part 241 and the sliding part respectively. When the second pushing part pushes the first pushing part 243 and the locking part 241 to move along the first direction F1, the return spring 22 is in a compressed state. At this time, the return spring 22 gives the locking part 241 a spring force toward the moving block 21. Then, when the first pushing part is disengaged from the pushing of the second pushing part, that is, when the second pushing part is not in contact with the first pushing part, the locking part 241 is subjected to the spring force and moves along the first direction F1 toward the moving block 21 on the sliding part and locks onto the moving block 21.

[0045] The drive assembly 3 also includes two drive rollers, which are drivenly connected to the conveyor belt 11. The drive device 33 is drivenly connected to at least one of the drive rollers to drive the conveyor belt 11 to transmit bolts along the first direction F1. In other words, the drive device 33 not only drives the push assembly 2 to push the bolts out of the receiving groove 12, but also drives the conveyor belt 11 via the drive roller connected to it. Using the same drive device 33 to drive both the push assembly 2 and the conveyor belt 11 simultaneously avoids the need for multiple drive devices 33 occupying space and also reduces energy consumption.

[0046] See Figure 1 The drive assembly 3 includes an overrunning clutch 32, which is connected between the drive roller and the drive device 33. The drive device 33 drives the drive roller to rotate unidirectionally by means of the overrunning clutch 32, so as to drive the conveyor belt 11 to unidirectionally transmit bolts along the first direction F1 toward the side closer to the receiving groove 12. That is, the drive roller connected to the overrunning clutch 32 rotates unidirectionally, thereby driving the conveyor belt 11 to move unidirectionally toward the receiving groove 12.

[0047] Continue reading Figure 1 As shown, the conveying assembly 1 includes a feeding hopper 13, which is located at the end of the conveyor belt 11 away from the receiving groove 12, and the opening of the feeding hopper 13 faces the conveying surface of the conveyor belt 11. When a bolt is placed in the feeding hopper 13, the bolt can slide through the opening onto the conveyor belt 11 and then be conveyed to the receiving groove 12 via the conveyor belt 11.

[0048] In some embodiments, the conveyor belt 11 is provided with a plurality of conveyor sections 111 whose longitudinal direction is parallel to the third direction F1. The plurality of conveyor sections 111 are arranged sequentially along the first direction F1, and a conveying groove is formed between two adjacent conveyor sections 111 for accommodating bolts that slide onto the conveyor belt 11 via the hopper 13. That is, the bolts slide onto the conveyor belt 11 via the hopper 13, and as the conveyor belt 11 moves along the first direction F1, the bolts on the conveyor belt 11 are sequentially accommodated in the conveying groove. It can be understood that the conveyor sections 111 are arranged along the third direction F1. If the direction F3 extends, the longitudinal direction of the conveying groove formed between two adjacent conveying sections 111 also extends along the third direction F3. After the bolt slides from the conveying section 111 to the conveying groove, its longitudinal extension direction is also parallel to the third direction F3. Therefore, the longitudinal direction of the bolt conveyed to the receiving groove 12 via the conveyor belt 11 is parallel to the third direction F3. That is, the setting of the conveying groove can make the longitudinal direction of the bolt contained therein parallel to the third direction F3, which makes it easy for the moving block 21 to push it away from the receiving groove 12, and easy for the machine tool fixture to clamp it.

[0049] In some embodiments, the drive device 33 includes a drive cylinder 331 and a moving frame 332. The drive cylinder 331 is used to drive the moving frame 332 to move toward the receiving groove 12 along the first direction F1 and to drive the moving frame 332 to move toward the feeding hopper 13 along the first direction F1. The moving frame 332 is provided with a pushing block 31 and a second pushing part at intervals along the first direction F1 on the side near the moving block 21.

[0050] It is understood that when the drive cylinder 331 drives the moving frame 332 to move along the first direction F1 toward the hopper 13, it simultaneously drives the push block 31 and the second push part to move along the first direction F1 toward the hopper 13. While the push block 31 abuts against the moving block 21, the second push part also abuts against the first push part. Then, the second push part pushes the first push part to move along the first direction F1, causing the locking part 241 to move along the first direction F1 and disengage from the moving block 21, thus unlocking the moving block 21 and allowing it to move along the third direction F3. Under the push of the push block 31, the moving block 21 moves along the third direction F3 and extends into the receiving groove 12, pushing the bolt located in the receiving groove 12 out of the receiving groove 12 along the third direction F3. At the same time, driven by the moving frame 332, the drive roller drives the conveyor belt 11 to move along the first direction F1 toward the hopper 13, causing the bolt located on the conveyor belt 11 to slide into the receiving groove 12.

[0051] When the drive cylinder 331 drives the moving frame 332 to move along the first direction F1 toward the receiving groove 12, it simultaneously drives the push block 31 and the second push part to move along the first direction F1 toward the receiving groove 12. The push block 31 disengages from the moving block 21. Under the action of the return spring 22, the moving block 21 moves along the third direction F3 toward the moving frame 332 and returns to its initial position. At the same time, the second push part also disengages from the first push part. Under the action of the limit spring 242, the locking part 241 moves along the first direction F1 toward the receiving groove 12 and locks onto the moving block 21 again. At this time, the drive roller stops rotating due to the action of the overrunning clutch 32.

[0052] In some embodiments, the mobile frame 332 and the drive roller are connected by a drive transmission, and an overrunning clutch 32 is provided between the mobile frame 332 and the drive roller. Specifically, the mobile frame 332 has a toothed plate 34 on the side near one of the drive rollers, and the overrunning clutch 32 has a gear 35 adapted to the toothed plate 34 at one end facing the mobile frame 332. When the mobile frame 332 moves toward the hopper 13, the toothed plate 34 drives the gear 35 to rotate, thereby driving the conveyor belt 11 to move toward the receiving groove 12. When the mobile frame 332 moves toward the receiving groove 12, the drive roller does not rotate due to the action of the overrunning clutch 32, that is, it does not drive the conveyor belt 11 to move toward the hopper 13.

[0053] In some embodiments, the pushing component 2 of the bolt feeding device 100 provided in this application further includes a buffer component 23. The buffer component 23 includes a plurality of buffer slide rods 233, a buffer spring 231, and a buffer plate 232. The moving block 21 is provided with a plurality of buffer tracks adapted to the buffer slide rods 233 on the side facing the moving frame 332. One end of the buffer slide rod 233 extends into the buffer track, and the other end is connected to the buffer plate 232. A buffer spring 231 is provided between the buffer plate 232 and the moving block 21, that is, one end of the buffer spring 231 is connected to the buffer plate 232, and the other end is connected to the moving block 21. Understandably, when the push block 31 pushes the moving block 21 to move along the third direction F3, the push surface and the buffer plate 232 abut against each other. The push block 31 provides a push force to the buffer plate 232 along the third direction F3. This push force is buffered by the buffer spring 231 and transmitted to the moving block 21, causing it to extend into the receiving groove 12 and push the bolt located in the receiving groove 12 out of the receiving groove 12. When the push block 31 withdraws the push force on the moving block 21, the buffer spring 231 is used to buffer the push force given to the moving block 21 by the reset spring 22, so as to prevent the moving block 21 from being subjected to excessive force and dislodging from the receiving groove 12.

[0054] The bolt feeding device 100 provided in this application mechanizes the bolt feeding process. Through the cooperation of the conveying component 1 and the pushing component 2, the bolts can be automatically shaped and pushed to the fixture of the processing machine tool, which facilitates the feeding of bolts. Specifically, two adjacent conveying sections 111 on the conveyor belt 11 form a conveying groove. The total length direction of the conveying groove extends along the third direction F3. That is to say, the bolts conveyed on the conveyor belt 11 are accommodated in the conveying groove and are made to be in a state where the longitudinal direction is parallel to the third direction F3 through the conveying groove, so that the bolts can slide into the receiving groove 12 and be pushed out of the receiving groove 12 by the moving block 21.

[0055] Furthermore, the drive assembly 3 of this application simultaneously drives the push assembly 2 and the conveyor belt 11 to move, saving the floor space required for additional drive equipment and saving energy. Specifically, after the bolt slides into the receiving groove 12, the drive cylinder 331 drives the moving frame 332 to move towards the hopper 13 along the first direction F1. The push block 31 abuts against the moving block 21, giving the moving block 21 a thrust to move towards the receiving groove 12. At the same time, the second push part pushes the first push part to move towards the hopper 13 along the first direction F1, causing the locking part 241 to move along the first direction F1 and disengage from the moving block 21, so that the moving block 21 is unlocked and moves along the third direction F3 under the pushing action of the push block 31, pushing the bolt located in the receiving groove 12 out of the receiving groove 12. At this time, the conveyor belt 11 transmits another bolt to the receiving groove 12 under the transmission of the frame, so as to feed the bolt when the moving block 21 pushes it out next time.

[0056] Then, the drive cylinder 331 drives the moving frame 332 to move towards the hopper 13 along the first direction F1. The push block 31 moves away from the moving block 21, the second push part moves away from the first push part, and the moving block 21 returns to its original position under the action of the return spring 22. The locking part 241 moves along the first direction F1 under the action of the limit spring 242 and re-locks onto the moving block 21. In this way, the drive cylinder 331 drives the moving frame 332 to reciprocate along the first direction F1 to feed the bolts.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
