Description

Technical Field

[0001] The utility model relates to the technical field of musical instrument processing equipment, in particular to a cross-line mechanism for easily turning around a total workpiece. Background Art

[0002] The original purpose of the capo was to adjust the pitch of the guitar. It is a commonly used auxiliary tool in folk guitar playing and singing. When changing the key, it can press the existing frets to raise the tune by a corresponding interval to make it coordinate with the singer's voice. Using the original fingering method to play greatly reduces the difficulty of changing the key.

[0003] The processing of a capo usually includes multiple workstations, and a turning operation is often required during the transportation from one workstation to another. The existing processing method usually implements the turning and transportation operations independently of each other, which increases the complexity of the structure and is not conducive to improving production efficiency. Utility Model Content

[0004] The utility model discloses a workpiece turning cross-line structure, which solves the technical problems of complicated structure and low efficiency of workpiece turning and conveying operation units in the prior art, and has the technical effects of reasonable structure, low production cost and high operation efficiency. The technical scheme adopted is as follows:

[0005] A workpiece turning and crossing line mechanism comprises a slot plate, a reversing seat, a rotating member, a swing arm and a driving unit, wherein the slot plate is provided with a guide slot extending from a first end to a second end, the reversing seat is arranged above the slot plate and can slide linearly from the first end to the second end under the action of the driving unit, the rotating member can support the workpiece upward, the rotating member passes through the reversing seat downward and is rotatably connected to the reversing seat, the end of the rotating member extending downward to the outside of the reversing seat is fixedly connected to the first end of the swing arm, the second end of the swing arm extends into the guide slot and can slide along the guide slot, when the second end of the swing arm slides in the guide slot and deviates from the sliding direction of the reversing seat, the rotating member can drive the workpiece to rotate and reverse.

[0006] On the basis of the above technical solution, the length section of the guide groove deviating from the sliding direction of the reversing seat extends along an arc and smoothly transitions with the adjacent length section.

[0007] On the basis of the above technical solution, the second end of the swing arm includes a follower ring, and the follower ring extends downward into the guide groove and is gap-matched with the guide groove.

[0008] On the basis of the above technical solution, the rotating member is fixedly connected with a tray upward, and the tray includes a cavity for accommodating the workpiece. The cavity axially penetrates the tray and forms a notch on the outer wall of the tray to facilitate the pushing and unpushing of the workpiece.

[0009] On the basis of the above technical solution, the two ends of the slot plate include two vertical plates, the two vertical plates are connected by guide rods, and the reversing seat is slidably connected to the two guide rods through a linear bearing.

[0010] On the basis of the above technical solution, the driving unit includes a fixedly arranged cylinder, a piston rod of the cylinder is fixedly connected to the reversing seat to drive the reversing seat to slide from the first end to the second end.

[0011] Based on the above technical solution, the slot plate spans across at least two workstations to facilitate the transportation and adjustment of the direction of the workpiece.

[0012] Beneficial Effects

[0013] The utility model has a reasonable structure. The guide groove includes a length section that deviates from the sliding direction of the reversing seat. When the follower block slides in the guide groove and deviates from the sliding direction of the reversing seat, the rotating member can drive the workpiece to rotate and reverse. In this way, the turning or reversing operation can be completed while the workpiece is being transported, which greatly saves time and is conducive to improving processing efficiency.

[0014] The utility model can realize the reversing operation by setting the guide groove and the guide rod, has a simple structure, low manufacturing cost and is conducive to promotion and application. In addition, the reversing angle can be determined by the length section of the guide groove deviating from the sliding direction of the reversing seat, which not only can set the steering angle steplessly, but also can avoid using electronic devices to control the steering angle, which is conducive to reducing the failure rate and ensuring continuous and stable production.
