Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a bolt feeding assembly. Background Technology

[0002] Bolts are common and essential workpieces in machining and manufacturing. In the production field, the bolt feeding process is gradually becoming more automated to improve the efficiency of bolt feeding.

[0003] In common bolt feeding devices, bolts are added to the feeding hopper and enter the feeding track through the opening at the bottom of the hopper. The bolts slide along the track for conveying. In order to ensure that the nut of the bolt is in the upward position when it is being fed, the opening at the bottom of the feeding hopper is narrow. This means that the bolt shank passes through the opening and the nut is above the opening. The narrow opening can easily cause the bolt to be blocked, affecting the bolt's passage through the bottom opening and reducing the bolt feeding efficiency. Utility Model Content

[0033] This invention utilizes a combination of a rotating rod, a rotating disk, an extrusion groove, a movable rod, a vibrating plate, a compression spring, a positioning fixture, and an electronic ruler. The rotating rod drives the rotating disk to rotate. As the disk rotates, the inner wall of the extrusion groove compresses the movable rod, pushing it and the vibrating plate upwards. This also causes the fixed block to compress and deform the compression spring. When the compression of the movable rod by the inner wall of the extrusion groove is released, the elasticity of the compression spring pushes the movable rod and the vibrating plate downwards, causing the vibrating plate to reciprocate and vibrate the bolts in the feeding groove. This prevents the bolts from becoming blocked and facilitates their entry into the feeding track. Simultaneously, the bolt slides downwards to the bottom of the feeding track, where the limiting block moves downwards to contact the top of the bolt, limiting and fixing it. The bolt then enters the positioning fixture. As the electronic ruler moves upwards and contacts the bottom of the bolt, it detects the bolt's length, ensuring the quality of bolt production.

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.

[0040] This utility model provides, for example Figure 1-4The bolt feeding assembly shown includes a feeding track 1 with a groove for the bolt to slide downwards along the groove; a feeding trough 2 fixedly installed at the top of the feeding track 1, the feeding trough 2 being funnel-shaped with a through groove at the bottom, allowing the bolt to slide through the through groove with the nut facing upwards, and the bolt entering the feeding track 1 through the through groove; a detection mechanism 3 located at the bottom of the feeding track 1, used to detect the length of the bolt, screening bolts and conveying those meeting the length requirements; and a vibration mechanism 4 located on the feeding trough 2, used to vibrate the bolts in the feeding trough 2 for feeding, facilitating their entry into the through groove.

[0041] Specifically, the detection mechanism 3 includes a limiting cylinder 31, which is positioned above the bottom end of the feeding track 1. The limiting cylinder 31 is electrically connected to an external power supply via an external first switch, and is used to drive a limiting block 32 to move vertically. The limiting block 32 is connected to the output end of the limiting cylinder 31. Moving the limiting block 32 downwards limits and fixes the top of the bolt sliding out from the bottom end of the feeding track 1, ensuring the stability of the bolt. A positioning fixture 33 is positioned at the bottom end of the feeding track 1, below the limiting block 32. The positioning fixture 33 has a slot, into which the bolt sliding out from the bottom of the feeding track 1 enters for positioning. A detection drive cylinder 34 is positioned below the bottom end of the feeding track 1. The detection drive cylinder 34 is electrically connected to an external power supply via an external second switch, and is used to drive a limiting block 32 to move vertically. The electronic ruler 35 is driven to move vertically. The electronic ruler 35 is connected to the output end of the detection drive cylinder 34. The electronic ruler 35 corresponds to the position of the limit block 32. The electronic ruler 35 is electrically connected to an external power supply through an external third switch. The electronic ruler 35 moves upward to contact the bottom end of the bolt and detect the length of the bolt. The transfer cylinder 36 is set at the bottom end of the feeding track 1. The output end of the transfer cylinder 36 is connected to the positioning fixture 33. The transfer cylinder 36 is electrically connected to an external power supply through an external fourth switch. The operation of the transfer cylinder 36 drives the positioning fixture 33 to move horizontally. When the bolt length is not qualified, the positioning fixture 33 moves to one side. The bolt in the slot moves with the positioning fixture 33 and drives the bolt to the through hole at the bottom end of the feeding track 1, so that the bolt falls into the defective material trough 5 through the through hole.

[0042] Furthermore, the vibration mechanism 4 includes a vibrating plate 41, which is disposed in the inner cavity of the feeding trough 2. There is a gap between the lower surface of the vibrating plate 41 and the inner wall of the feeding trough 2. The movement of the vibrating plate 41 drives the bolts in the feeding trough 2 to vibrate. Movable rods 42 are fixedly connected to the lower surface of the vibrating plate 41 and are arranged at intervals. Multiple movable rods 42 are used to install the vibrating plate 41 and drive the vibrating plate 41 to move. Movable grooves are opened on both sides of the feeding trough 2, and their inner cavities slide through the movable rods 42. The movable groove is used to install the movable rod 42 and the compression spring 43. The compression spring 43 is set in the movable groove and is movably connected to the movable rod 42. The elastic force of the compression spring 43 pushes the fixed block 44 and the movable rod 42 downward, causing the vibrating plate 41 to move downward. The fixed block 44 is fixedly connected to the movable rod 42 and fits against the bottom end of the compression spring 43. The fixed block 44 moves together with the movable rod 42 and is used to compress and deform the compression spring 43. The fixed frame 45 is fixedly connected to one side of the outer wall of the feeding trough 2. The fixed frame 45 is used to install the rotating rod 46; the two ends of the rotating rod 46 are rotatably connected to the fixed frame 45, and the rotating rod 46 is used to drive the rotating disk 47 to rotate; the rotating disk 47 is fixedly connected to the middle of the rotating rod 46, and the rotating disk 47 is set at the bottom of one of the movable rods 42, and is used to squeeze and push the movable rod 42 to move; the squeezing groove 48 is opened on the rotating disk 47, and the squeezing groove 48 is slidably inserted into one end of the movable rod 42. The squeezing groove 48 is arranged in a ring shape and is eccentrically arranged with the rotating disk 47. As the rotating disk 47 rotates, the inner wall of the squeezing groove 48 squeezes the movable rod 42, pushing the movable rod 42 and the vibrating plate 41 to move upward, and driving the fixed block 44 to compress the spring 4. 3. Compression deformation: When the compression of the inner wall of the compression groove 48 on the movable rod 42 is released, the elastic action of the compression spring 43 is used to push the movable rod 42 and the vibrating plate 41 downward, so that the vibrating plate 41 reciprocates and vibrates the bolts in the feeding groove 2; Positioning rod 49: The positioning rod 49 is fixedly connected to the lower surface of the vibrating plate 41. The positioning rod 49 is slidably inserted into one side of the feeding groove 2. The positioning rod 49 moves together with the vibrating plate 41 to ensure the stability of the vibrating plate 41; Drive motor 410: The output end of the drive motor 410 is connected to one end of the rotating rod 46. The drive motor 410 is electrically connected to an external power supply through an external fifth switch. The operation of the drive motor 410 drives the rotating rod 46 and the rotating disk 47 to rotate.
