[0030] Referring to Figures 1 to 8 , the present utility model provides a bolt feeding mechanism for clamp assembly, including a hopper 1 and a feeding seat 2 arranged on one side of the hopper 1. Symmetrically arranged material grooves 3 are provided on the feeding seat 2. Symmetrically arranged guide rails 4 are connected to the hopper 1, and the other ends of the guide rails 4 are spliced with the material grooves 3. The hopper 1 is a vibrating disk, which can vibrate the internal bolts out and transport them to the material grooves 3 one by one through the guide rails 4. Since the width of the guide rails 4 is adapted to the diameter of the bolts, the bolts can be transported vertically. A feeding block 5 is slidably installed on the feeding seat 2. Two feeding grooves 6 are provided on the feeding block 5. A first propulsion component is connected to one side of the feeding block 5. The first propulsion component is used to push the feeding block 5 to splice or stagger the feeding grooves 6 with the material grooves 3. Claws 7 are symmetrically arranged above the feeding block 5; when the first propulsion component pushes the feeding block to move so that the feeding grooves 6 are spliced with the material grooves 3, the bolts can be pushed from the material grooves 3 into the feeding grooves 6 to complete feeding. When the first propulsion component pushes the feeding block to move so that the feeding grooves 6 are staggered with the material grooves 3 and moves to the position below the claws 7, which is the feeding station, the claws 7 can clamp the bolts for feeding.

[0031] In some embodiments, such as Figures 4 to 7As shown in the figure, a second propulsion assembly is connected to one side of the loading seat 2. The second propulsion assembly includes a second propulsion cylinder 8 and a material blocking block 9. The side end of the material blocking block 9 is connected to the second propulsion cylinder 8. A plurality of guide holes 10 are provided through the loading seat 2. A plurality of guide rods 11 passing through the guide holes 10 are correspondingly provided on the material blocking block 9. The second propulsion cylinder 8 can push the material blocking block 9 to make the guide rods 11 slide along the guide holes 10. A plurality of baffle plates are inserted on the guide rods 11. A connecting seat 12 is provided at the upper end of the baffle plates. A material blocking column 13 is fixed on each of the connecting seats 12. Two through holes 14 are correspondingly provided above the guide holes 10 on the loading seat 2. These through holes 14 are all communicated with the material chute 3. Therefore, when the guide rods 11 move horizontally, the connecting seats 12 are driven to move, so that the material blocking columns 13 are inserted into the through holes 14 and the material chute 3, thereby closing the material chute 3. The opening and closing of the material chute 3 can be controlled by the insertion and removal of the material blocking columns 13. Specifically, the baffle plates include a first baffle plate group 15 and a second baffle plate group 16 arranged alternately. Among them, the first baffle plate group 15 is arranged on the right side of the material chute 3, and the second baffle plate group 16 is arranged on the left side of the material chute 3. The connecting seats 12 on the first baffle plate group 15 and the second baffle plate group 16 are all arranged on one side. Since the first baffle plate group 15 and the second baffle plate group 16 have the same structure and are arranged in the opposite direction, the material blocking columns 13 on the first baffle plate group 15 correspond to the through holes 14 close to the feeding block 5, and the material blocking columns 13 on the second baffle plate group 16 correspond to the through holes 14 close to the guide rail 4. When the second propulsion cylinder 8 ejects, the material blocking columns 13 on the first baffle plate group 15 are inserted into the material chute 3 to close the end of the material chute 3. At this time, the material blocking columns 13 on the second baffle plate group 16 are separated from the end of the material chute 3 to unlock the front end of the material chute 3, so that a single bolt can enter the material chute 3 and be blocked by the material blocking columns 13 of the first baffle plate group 15. At this time, the feeding block 5 is ejected by the first propulsion cylinder 17 to clamp the bolt. When the feeding block 5 returns and the loading chute 6 cooperates with the material chute 3, the second propulsion cylinder 8 resets to drive the material blocking columns 13 on the first baffle plate group 15 to separate from the material chute 3 to achieve unlocking. The bolts behind push the bolts in the material chute 3 into the loading chute 6. At this time, the material blocking columns 13 on the second baffle plate group 16 enter the material chute 3 again to lock the front end of the material chute. In this embodiment, the first propulsion assembly is the first propulsion cylinder 17. The side wall of the feeding block 5 is connected to the first propulsion cylinder 17. A chute 18 is provided on the loading seat 2. The feeding block 5 is slidably arranged on the chute 18. An avoidance groove 19 corresponding to the loading chute 6 is provided on one side of the loading seat 2 where the chute 18 is located. The feeding block 5 slides along the chute 18 to the material taking station under the push of the first propulsion cylinder 17. At this time, the outer loading chute 6 is separated from the loading seat 2, and the inner loading chute 6 cooperates with the avoidance groove 19. The clamping jaws can extend from the loading seat 2 to clamp the bolt as a whole.

[0032] In some embodiments, such as Figures 1 to 3 and Figure 8As shown in the figure, a bracket 20 is provided on one side of the loading seat 2. A driving mechanism is provided on the bracket 20, and a movable table 21 is installed on the driving mechanism. The clamping jaws 7 are symmetrically fixed on the movable table 21, and the clamping jaws 7 are driven to move by the movable table 21. Specifically, the driving mechanism includes a driving motor 22, a swing rod 23 and a roller 24. A driving motor 22 is installed on one side of the bracket 20. The rotating shaft of the driving motor 22 passes through the bracket 20 and is connected to the swing rod 23. The swing rod 23 is connected to the roller 24 through a connecting shaft 25. An inverted U-shaped groove 26 is provided on the bracket 20, and the roller 24 is rotatably installed in the U-shaped groove 26. One end of the connecting shaft 25 is fixed inside the roller 24, and the other end is connected to the movable table 21. A transverse slide rail 27 is provided below the U-shaped groove 26 on the bracket 20. A slider 3 is slidably installed on the transverse slide rail 27. A vertical slide rail 28 is fixed on the connecting shaft 25. The movable table 21 is fixed at the bottom of the vertical slide rail 28. The vertical slide rail 28 is slidably matched with the slider 32. When the swing rod 23 swings, it will pull the vertical slide rail 28 to rise and fall through the roller 24 and the connecting shaft 25. During this process, the slider 32 is simultaneously stressed and slides along the transverse slide rail 27, so that the movable table 21 and the clamping jaws 7 perform lifting and transverse movement, and the workpiece is clamped from the loading chute 6 and placed on the working station. In this embodiment, a dividing plate 29 is provided on one side of the loading seat 2. A discharging seat 30 corresponding to the clamping jaws 7 is fixed on the dividing plate 29. A placing groove 31 corresponding to the bolt is provided in the discharging seat 30. After the clamping jaws 7 move along the U-shaped groove 26 following the movable table 21 and are located above the discharging seat 30, discharging can be performed at this time.

[0033] A bolt loading mechanism for clamp assembly provided by the present utility model can sequentially place workpieces into the loading chute one by one when the loading seat cooperates with the feeding block, and then the feeding block drives the workpiece to move and then pick up the workpiece. Moreover, the chute cooperates with the baffle on one side to realize the opening and closing function, and the effect of conveying one workpiece each time the chute is opened and closed can be achieved, realizing the separate transportation and clamping of the workpiece, so as to ensure that the workpiece will not be misaligned, offset or overlapped during the assembly process, and improve the assembly accuracy and efficiency.
