Description

Technical Field

[0001] This utility model relates to the field of metal pin processing technology, specifically a metal pin conveying device. Background Technology

[0002] In the field of machining, metal pins are widely used as basic connecting parts in the assembly of various products, and the efficiency and accuracy of their conveying process directly affect the overall production progress. Currently, the conveying of metal pins mostly adopts a combination of vibratory feeders and linear feeders. The vibratory feeder guides the metal pins one by one into the conveyor track, and then the linear feeder conveys them to the subsequent processing station.

[0003] However, while existing metal pin conveying devices can achieve continuous transport, they often lack the ability to precisely adjust and fix the posture of the metal pins for stages requiring positioning, inspection, or processing midway. Because metal pins are cylindrical or similar in shape, they are prone to deviation during transport, preventing them from reaching the subsequent workstation in the preset precise orientation, thus affecting the accuracy of subsequent automated operations and product quality. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a metal pin conveying device, which aims to solve the problem that the existing metal pin conveying device cannot make the metal pin reach the subsequent position in a preset precise position.

[0005] This utility model provides the following technical solution: a metal pin conveying device, comprising a machine base, a rotatable chain in the middle of the machine base, a ring of bearing seats evenly arranged on the chain, a conveying baffle on the machine base, a notch in the middle of the conveying baffle, the chain located within the notch, a pair of left and right breaks on the conveying baffle, an adjustment mechanism on the machine base opposite the breaks, the adjustment mechanism comprising an adjustment table slidably mounted on the machine base, a vertical plate on the machine base opposite the adjustment table, a pair of guide rods on the front of the adjustment table, a connecting rod on the back of the adjustment table, an adjustment seat slidably mounted on the guide rod, the end of the guide rod being limited and mounted on the front of the adjustment seat, multiple pins spaced apart on the adjustment seat, an adjustment spring on the guide rod located between the adjustment seat and the adjustment table, the tail of the connecting rod passing through the vertical plate on the same side and being limited and mounted on the back of the vertical plate, a return spring on the connecting rod located between the adjustment table and the vertical plate, and an adjustment drive mechanism on the machine base for driving the two adjustment tables to move relative to each other simultaneously.

[0006] Furthermore, the top surface of the machine tool has a pair of top openings, and the adjustment drive mechanism includes a pair of slides slidably installed inside the upper part of the machine tool. The slides are provided with connecting frames, which pass through the top openings and are connected to the adjustment platform at the same position. The end faces of the two slides are provided with opposing inclined surfaces. The machine tool is provided with a push cylinder, and the drive shaft of the push cylinder is provided with a push seat. A pair of push wheels are rotatably provided on the push seat, and the push wheels are in rolling contact with the inclined surfaces at the same position.

[0007] Furthermore, both sides of the machine tool are provided with limiting plates, and the limiting plates are provided with limiting rods, which are positioned toward the slide block at the same location.

[0008] Furthermore, all the inclined surfaces are arranged facing downwards and inwards.

[0009] Furthermore, a limiting rod is provided on the machine base corresponding to the upright plate, and the adjusting table is located between the limiting rod and the upright plate.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

An adjustment spring 12 is provided on the guide rod 8 between the adjustment seat 10 and the adjustment table 7. The tail of the connecting rod 9 passes through the upright plate 27 on the same side and is limited and installed on the back of the upright plate 27. A return spring 13 is provided on the connecting rod 9 between the adjustment table and the upright plate. The machine base 1 is provided with an adjustment drive mechanism for driving the two adjustment tables 7 to move relative to each other simultaneously.

[0020] Figure 2 The device includes a machine base 1. A drive sprocket 14 and a driven sprocket 15 are rotatably mounted on the center of the machine base via bearing seats. A rotatable chain 2 is fitted between the drive sprocket 14 and the driven sprocket 15. The drive sprocket 15 is driven by a geared motor 16 to achieve uniform rotation of the chain. A ring of bearing seats is evenly arranged on the chain. The top surface of each bearing seat has a U-shaped groove adapted to fit a metal pin for placing and positioning the metal pin.

[0021] A conveyor baffle is fixedly mounted on the machine base. A notch is cut in the middle of the conveyor baffle, and the chain is positioned within the notch, allowing the support seat to move smoothly within the notch. The conveyor baffle has a pair of left and right breaks. An adjustment mechanism is located on the machine base opposite these breaks. The adjustment mechanism includes an adjustment table slidably mounted on the machine base. A pair of parallel guide rods are located on the front of the adjustment table, and a connecting rod is located on the back of the adjustment table. The ends of the guide rods are fixed to the front of the adjustment seat to prevent it from detaching from the guide rods. Multiple ejector pins are spaced apart on the adjustment seat. The ends of the ejector pins have a rounded transition design to avoid scratching the surface of the metal pins. An adjustment spring is fitted on the guide rod between the adjustment seat and the adjustment table. The two ends of the adjustment spring abut against the adjustment seat and the adjustment table respectively, providing elastic support for the adjustment seat.

[0022] A vertical plate is fixedly installed on the machine base at the position corresponding to the connecting rod. The tail of the connecting rod passes through the vertical plate on the same side and is limited by the stop 17 and installed on the back of the vertical plate. A return spring is sleeved between the connecting rod and the adjusting table and the vertical plate. The two ends of the return spring abut against the adjusting table and the vertical plate respectively to realize the automatic reset of the adjusting table.

[0023] As a specific structure, combined Figure 1 , Figure 4 The machine base 1 has a pair of top openings 18 on its top surface. The adjustment drive mechanism includes a pair of slides 19 that are slidably installed on the upper part of the machine base. The slides are provided with a connecting frame 20. The connecting frame 20 passes through the top openings 18 and is connected to the adjustment platform 7 at the same position. The end faces of the two slides 19 are provided with opposite inclined surfaces 21. The machine base 1 is provided with a push cylinder 22. The drive shaft of the push cylinder 22 is provided with a push seat 23. A pair of push wheels 24 are rotatably provided on the push seat 23. The push wheels 24 are in rolling contact with the inclined surfaces 21 at the same position.

[0024] Because the two slides have opposing inclined surfaces on their opposite end faces, with both inclined surfaces facing downwards and inwards. When the push cylinder is activated, the push seat drives the push wheel forward or backward. The push wheel rolls into contact with the inclined surface on the slide at the same position, and the inclined surface converts the linear motion of the push cylinder into the horizontal movement of the two slides towards or away from each other. At the same time, the adjusting table also moves along with the slide on the same side.

[0025] Figure 4 In this design, both sides of the machine base 1 are provided with limiting plates 25, and each limiting plate 25 is provided with a limiting rod 26, which is positioned towards the slide block 19 at the same location. The function of the limiting rod is to restrict the movement range of the slide block, preventing it from exceeding the specified range during movement, and ensuring the normal operation and adjustment accuracy of the adjustment mechanism.

[0026] The machine base 1 is provided with a limiting rod 28 corresponding to the vertical plate, and the adjusting table is located between the limiting rod and the vertical plate. The limiting rod and the vertical plate constitute a limiting range, and the adjusting table is located within the corresponding limiting range. The limiting range is used to limit the movement range of the adjusting table.

[0027] The working principle of the above embodiment is as follows: First, the reduction motor is started, causing the chain to start rotating. The bearing seat drives the metal pin to be conveyed on the conveyor frame as the chain rotates. When the metal pin is conveyed to the adjustment position, the chain stops rotating, the push cylinder is started, and the drive shaft of the push cylinder pushes the push seat to move. The push wheel on the push seat rolls on the inclined surface of the slide. Due to the relative arrangement of the inclined surfaces, the two slides move relative to each other at the same time.

[0028] The slide moves the adjusting table relative to the connecting frame, causing the guide rod and adjusting seat on the adjusting table to move accordingly. The ejector pin on the adjusting seat contacts the metal pin, adjusting its position. During the adjustment process, the adjusting spring provides elastic force, enabling the adjusting seat to self-adjust according to the actual situation of the metal pin, ensuring the smoothness and accuracy of the adjustment.

[0029] Once the metal pin is in position, the push cylinder is closed, and the return spring quickly returns the adjusting table to its initial position, preparing it for the next adjustment. The chain continues to rotate, transporting the adjusted metal pin to the next process, completing the metal pin transport process.

[0030] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
