Description

Technical Field

[0001] This utility model belongs to the field of fastener processing technology, specifically relating to a sorting pusher. Background Technology

[0002] Fasteners are a wide range of mechanical parts used for fastening connections. They typically include various types such as bolts, studs, screws, and nuts. During the fastener production process, feeding devices are often needed to transport fasteners. Using feeding devices can automate the transport of fasteners from one process to the next for subsequent assembly, weighing, and other processes.

[0003] In fastener processing, a thread rolling machine is required. A thread rolling machine is a processing device for the outer surface of cylindrical workpieces. It consists of two identical thread rolling plates with the same thread profile and helix angle as the bolt thread. When the thread rolling plates move back and forth, they roll the bolt blank between the two plates to form threads. One bolt thread is processed with one round trip of the thread rolling plates, which is quite fast. Corresponding to the thread rolling machine, a fastener feeding and unloading device is required to feed the fasteners into the machine.

[0004] For example, Chinese patent application number CN202420066280.5 discloses a screw pushing mechanism for a thread rolling plate with broken ends of straw rope, including a thread rolling machine body and bolts, a feeding hopper, support rods fixed on both sides, the bottom of the support rods placed on the ground; a discharge plate connected to the feeding hopper, with a pressure plate connected to the top middle of the discharge plate and the feeding hopper; a vertical device installed at the end of the discharge plate away from the feeding hopper; a fixed platform installed at the end of the thread rolling machine body away from the feeding hopper; thread rolling plates installed on both sides of the fixed platform; and a pushing device installed at the end of the vertical device away from the discharge plate.

[0005] Further research by the applicant revealed that existing thread rolling plate pushing structures primarily rely on motors or cylinders to drive push rods. The motors or cylinders control the push rod's pushing rhythm based on the reciprocating rhythm of the moving thread rolling plate on the thread rolling machine. When pushing fasteners, there is room for improvement in its pushing efficiency. Specifically, the ready-to-push position of the fastener before it is pushed is always random, affecting the accuracy of the coordination with the pushing components. This often results in fasteners being pushed without contact or at an angle, leading to a decrease in the efficiency and quality of the thread rolling process. Utility Model Content

[0036] like Figure 1 - Figure 6 As shown, the present invention provides a sorting pusher, which includes a body 1, a pusher blade holder 3, a pusher blade shaft 40, a pusher blade body 41, a separating needle 42, a swinging component 43, and a linkage assembly 5.

[0037] The machine body 1 is equipped with a linkage component 5 and a discharge guide rail 2 for conveying fasteners;

[0038] The pusher knife holder 3 is located on the side of the discharge guide rail 2, and a guide cavity 30 extending toward one side of the discharge guide rail 2 is provided in the pusher knife holder 3;

[0039] The pusher shaft 40 is placed in the guide cavity 30, the pusher body 41 is placed on the side of the pusher seat 3 and connected to the pusher shaft 40, and the distributing needle 42 is slidably connected to the pusher seat 3.

[0040] The swing component 43 is rotatably connected to the pusher blade holder 3, and the two ends of the swing component 43 are respectively connected to the pusher blade shaft 40 and the linkage assembly 5;

[0041] Driven by the power component, the linkage component 5 forces the swing component 43 to rotate, and drives the pusher shaft 40 to reciprocate along the guide cavity 30, while the pusher body 41 and the distributing needle 42 move in opposite directions.

[0042] This feeder, as a pre-processing structure for the thread rolling mechanism, enables fasteners to be pushed into the thread rolling mechanism in an orderly, uninterrupted, and rapid manner. The various components of the feeder adopt a clever mechanical linkage structure, which can share the same power source to realize the fastener blocking / releasing and pushing processes. Due to the use of pusher knife holder 3, swinging component 43, pusher knife shaft 40, etc., the above blocking / releasing and pushing processes can maintain a synchronous rhythm, avoiding the occurrence of fasteners being pushed empty or at an angle.

[0043] In this embodiment, the fasteners are specifically bolts and screws, and their size is not specifically limited, as long as they can be hung upside down on the guide rail.

[0044] In the discharge guide rail 2, an existing bolt feeding device is used to guide a batch of bolts onto the discharge guide rail 2. The distribution needle 42 controls the passage of bolts, and the feeding of bolts to the thread rolling mechanism is achieved through the pusher blade 41.

[0045] Specifically, such as Figure 2 , Figure 6 As shown, the linkage assembly 5 includes an eccentric cam 50 driven by a power component (not shown in the figure), a swing body 51 cooperating with the eccentric cam 50, and a hinge rod 52 connecting the swing component 43 and the swing body 51. The power component is mounted on the machine body 1 and can be a motor, whose output shaft is connected to the eccentric cam 50.

[0046] When the end of the pusher blade 41 moves close to the discharge guide rail 2, the distribution pin 42 needs to move in the opposite direction to the pusher blade 41 so that the distribution pin 42 retracts, allowing the fasteners in the gap 22 of the discharge guide to continue moving forward without being blocked by the distribution pin 42. The fasteners are pushed by the pusher blade 41 to complete the feeding, and then acted upon by the thread rolling mechanism installed on the machine body 1 to complete the thread rolling operation of the fasteners.

[0047] Specifically, the opposing movements of the distributing needle 42 and the pusher blade 41 are accomplished by the following collaborative mechanism:

[0048] A rotating shaft 60 is connected to the swing member 43. A pusher blade 61 is rotatably connected in the pusher blade holder 3. The head of the pusher blade 61 cooperates with the outside of the rotating shaft 60, and the tail of the pusher blade 61 cooperates with the distributing needle 42.

[0049] When the swing member 43 is acted upon by the linkage mechanism, the rotating shaft 60 connected to the side arm of the swing member 43 deflects together. When the side arm of the swing member 43 drives the pusher shaft 40 and the pusher body 41 to move along the direction of the guide cavity 30, the deflected rotating shaft 60 is squeezed by the head of the actuating plate 61, causing the tail of the actuating plate 61 to squeeze and push the distributing needle 42 in the opposite direction.

[0050] The pusher holder 3 has a notch 300 on its side. The notch 300 allows the pusher shaft 40 to be connected to the pusher body 41 on the side of the pusher holder 3, and to be driven together to reciprocate to push / feed the fasteners in the track.

[0051] The discharge end of the discharge guide rail 2 has a notch 23, and the end of the distributing needle 42 can cooperate with the notch 23.

[0052] The end of the distributing needle 42 is located at the notch 23, which can block the fasteners placed on the discharge guide rail 2. In conjunction with the pusher blade 41, the purpose of orderly discharge can be achieved.

[0053] like Figure 4 , Figure 5 As shown, specifically, the material discharge guide 2 includes a left rib 20 and a right rib 21 arranged in parallel, with a gap 22 between the left rib 20 and the right rib 21. The cylindrical body of the bolt fastener is located in the gap 22, while the head is located above the gap 22. Due to the setting of the gap 22, the fastener is in an inverted state.

[0054] The pusher knife holder 3 has an upper end with a mounting groove 31 that conforms to the shape of the distributing needle 42. The distributing needle 42 is Z-shaped.

[0055] In addition, a spring seat 32 is connected to the outside of the pusher knife holder 3, and the tail of the distributing needle 42 is engaged with the spring seat 32.

[0056] A spring (not shown in the figure) is provided between the tail of the dispensing needle 42 and the spring seat 32. To prevent the dispensing needle 42 from disengaging from the pusher knife seat 3 during reciprocating movement, a cover plate (not shown in the figure) can be provided on the top of the pusher knife seat 3 to ensure the lateral movement of the dispensing needle 42.

[0057] Additionally, a tooth-rolling seat 7 is provided on the machine body 1, located on the outer side of the pusher blade body 41. This tooth-rolling seat 7 serves as an accessory to the tooth-rolling mechanism, and through its structure, it securely mounts the tooth-rolling mechanism (not shown in the figure) onto the machine body 1.

[0058] The end of the feed needle 42 is located at the notch 23, which can block the fasteners placed on the feed guide rail 2. In conjunction with the pusher blade 41, it can achieve the purpose of orderly feed. This structure has high reliability and ensures the accuracy of fastener feed / push. When combined with the thread rolling mechanism, it can achieve the purpose of fastener thread processing quickly.

[0059] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
