Description

Technical Field

[0001] This utility model relates to the field of material handling shaft technology, specifically a long shaft type material handling shaft for arranging material handling. Background Technology

[0002] A material handling shaft is a specialized shaft component used for material handling operations by robotic arms. Its main function is to achieve fast and safe material handling by engaging the shaft sleeve with the material (such as a round tube).

[0003] Its working principle is that the robotic arm drives the material picking shaft to move. After the bushing is inserted into the target material (such as a round tube), the material is fixed by the friction between the bushing and the material, and the picking action is completed. The material picking shaft is mainly used in automated welding equipment. By cooperating with the robotic arm, it can achieve high-speed and precise material picking operation and reduce manual intervention.

[0004] Existing technology CN202321969156.1 discloses a material-picking shaft, which includes a shaft handle, a shaft core, a material-picking adjustment ring, and a shaft sleeve for connecting to a robotic arm. One end of the shaft core is inserted into one end of the shaft handle, and the material-picking adjustment ring is fitted onto the shaft core and fixes it. The shaft sleeve is fitted onto the other end of the shaft core. This prior art, by fixing the shaft core to the shaft handle, the material-picking adjustment ring to the other end of the shaft core, and the shaft sleeve fitted onto the shaft core, allows the material-picking device to be mounted on the material-picking robotic arm of a welding equipment at one end of the shaft handle. The movement of the robotic arm moves the material-picking shaft to pick up material. The shaft sleeve of the material-picking shaft is inserted into a round tube, thereby utilizing the interaction between the shaft sleeve and the round tube to prevent the welding wire from falling off, thus achieving material picking.

[0005] Based on a review of existing technologies and practical product implementation, it was found that traditional material handling shafts can only handle a single roll of material in a single process, and cannot handle multiple rolls of material at the same time. As a result, the material handling efficiency is low and there are certain shortcomings in actual use. Therefore, this utility model proposes a long shaft material handling shaft that can handle multiple rolls of material at the same time. Utility Model Content

[0006] The purpose of this invention is to provide a long-shaft type material picking shaft for arranging and picking up materials, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a long shaft type material picking shaft for arranging material picking, including an outer shaft housing, a material passing shaft fixedly installed at one end of the outer surface of the outer shaft housing, the material passing shaft having a hollow internal structure, a piston being disposed inside the outer shaft housing, the piston being slidably connected to the outer shaft housing, a shaft core rod being fixedly installed at the center position of the outer surface of the piston near the material passing shaft, one end of the shaft core rod being inserted into the material passing shaft, the shaft core rod being in slidable contact with the material passing shaft, the top end of the shaft core rod having a tapered structure, a plurality of expansion keys contacting the tapered surface of the top end of the shaft core rod, each of the expansion keys being in slidable contact with the material passing shaft, and the lower surface of the expansion key being an inclined surface.

[0008] Preferably, a return spring is installed on the outer surface of the piston, the return spring is sleeved on the outside of the shaft core rod, and the tail end of the return spring is fixedly connected to the inner wall of the outer shaft housing.

[0009] Preferably, each of the expansion keys has an inner groove on its outer surface, and an elastic ring is tightened between the inner grooves of the expansion keys.

[0010] Preferably, an air nozzle is fixedly mounted on the top outer surface of the outer shaft housing.

[0011] Preferably, a plurality of evenly distributed fixing holes are fixedly installed on the outer surface of the outer shaft housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model features a long-shaft material threading shaft that can be inserted into several neatly arranged circular holes in a roll of material. This allows for the threading and retrieving of multiple materials simultaneously. In practical use, it offers the advantage of simultaneous threading and retrieving of multiple materials. Compared to traditional material retrieving shafts, this utility model, through its long-shaft design, enables unified threading and retrieving of neatly arranged materials. Multiple sets of materials can be transferred in a single retrieving motion, significantly improving retrieving efficiency and demonstrating superior practicality and efficiency.

[0014] Meanwhile, the expansion key can be protruded and expanded under the driving action of the internal shaft core structure. The protruding expansion key has a certain end limiting effect, which can effectively prevent the roll material on the picking shaft from slipping off the end of the feeding shaft. It has a good end anti-drop blocking effect, improves the stability during picking, and makes it more convenient to use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-4 One embodiment of this utility model is a long shaft type material picking shaft for arranging material picking, including an outer shaft shell 1, a material passing shaft 2 fixedly installed on one end of the outer surface of the outer shaft shell 1, the inside of the material passing shaft 2 is a hollow structure, and the material passing shaft 2 is a long shaft body structure design.

[0024] For details, please refer to the appendix of the instruction manual. Figure 4 As shown, a piston 3 is installed inside the outer shaft housing 1. The piston 3 is slidably connected to the outer shaft housing 1. A core rod 5 is fixedly installed at the center of the outer surface of one end of the piston 3 near the material feeding shaft 2. One end of the core rod 5 is inserted into the material feeding shaft 2, and the core rod 5 slides in contact with the material feeding shaft 2. Thus, when the piston 3 moves internally, it can synchronously drive the core rod 5 to move. The top end of the core rod 5 is a tapered structure. Several expansion keys 6 are in contact with the tapered surface of the top end of the core rod 5. Each expansion key 6 slides in contact with the material feeding shaft 2, thus ensuring that the expansion key 6 protrudes and expands inside the material feeding shaft 2. The protruding expansion key 6 has a certain end limiting effect, which can effectively prevent the roll material of the picking shaft from slipping off the end of the material feeding shaft 2. The lower surface of the expansion key 6 is a slope.

[0025] The above structure is explained in detail below; please refer to the appendix of the instruction manual for specific details. Figure 4 As shown, when the piston 3 moves from right to left under the driving force of the gas, the piston 3 can synchronously drive the shaft core rod 5 to move. Since the top of the shaft core rod 5 is a conical inclined surface, when the shaft core rod 5 moves from right to left, it can abut against the outer expansion key 6 through the conical inclined surface, so that several expansion keys 6 protrude and expand from the material feeding shaft 2, thereby giving the protruding expansion key 6 a certain end limiting effect. This is the expansion state of the material feeding shaft of this utility model.

[0026] In this embodiment, in order to facilitate structural reset, a reset spring 4 is installed on the outer surface of the piston 3. The reset spring 4 is sleeved on the outside of the shaft core rod 5, and the tail end of the reset spring 4 is fixedly connected to the inner wall of the outer shaft shell 1.

[0027] With this structural design, when the piston 3 moves from right to left, it can synchronously compress the return spring 4, putting the return spring 4 in a compressed state. When the air pressure disappears, the compressed return spring 4 elastically resets, thereby pushing against the piston 3, causing the piston 3 and the shaft core rod 5 to move and reset together from left to right, completing the reset work of the internal shaft core structure.

[0028] In this embodiment, in order to drive the expansion key 6 to perform structural reset, please refer to the appendix of the specification for details. Figure 3 As shown, each expansion key 6 has an inner groove on its outer surface. An elastic ring 7 is tightened between the inner grooves of several expansion keys 6. When the expansion key 6 protrudes from the material passing shaft 2, the elastic ring 7 can be spread apart between several expansion keys 6. When the piston 3 moves to reset under the action of the reset spring 4, the spread elastic ring 7 can contract inward, thereby driving the expansion member 6 to contract inward and reset.

[0029] In this embodiment, in order to inject high-pressure air and drive the piston 3 to move, an air nozzle 8 is fixedly installed on the top outer surface of the outer shaft housing 1, through which high-pressure air can be connected.

[0030] In this embodiment, a plurality of evenly distributed fixing holes 9 are fixedly installed on the outer surface of the outer shaft housing 1. The material picking shaft of this utility model can be installed as a whole on an external robotic arm through the fixing holes 9.

[0031] Working principle: When in use, the material picking shaft of this utility model can be installed on an external robot arm through the fixing hole 9, so that the external robot arm can perform material picking and driving work.

[0032] When the material picking shaft picks up materials, it can be inserted into several neatly arranged round holes of the roll material through the long shaft 2. In this way, the long shaft type material picking shaft 2 can complete the material picking and picking work between multiple items. In actual use, it has the practical characteristics of simultaneous material picking and picking of multiple items. Compared with the traditional material picking shaft, this utility model, through the structural design of the long shaft, can perform uniform material picking and picking work on neatly arranged materials. In a single material picking movement, multiple sets of materials can be transferred, which greatly improves the material picking efficiency, has a better practical effect, and is more practical and has higher material picking efficiency.

[0033] After the material handling shaft is inserted into the array of materials by an external robotic arm, high-pressure air is injected through the air nozzle 8. The injected high-pressure gas drives the piston 3 to move. See the attached instruction manual for details. Figure 4 As shown, when the piston 3 moves from right to left under the drive of gas, the piston 3 can synchronously drive the shaft core rod 5 to move. Since the top of the shaft core rod 5 is a conical inclined surface, when the shaft core rod 5 moves from right to left, it can abut against the outer expansion key 6 through the conical inclined surface, causing several expansion keys 6 to bulge out from inside the material passing shaft 2. This gives the bulging expansion key 6 a certain end-limiting effect. At this time, several materials inserted for picking cannot fall off from the bulging end, improving the conveying stability after picking up materials. It has good end-limiting material picking characteristics and is more practical.

[0034] After the expansion key 6 expands, the external robot arm transports several materials threaded on the material threading shaft 2 to the designated area, completing the transfer work after material retrieval.

[0035] When piston 3 moves from right to left, it synchronously compresses return spring 4, putting return spring 4 in a compressed state. When the air pressure disappears, the compressed return spring 4 elastically resets, thereby pushing against piston 3 and causing piston 3 and shaft core rod 5 to move and reset together from left to right, completing the reset work of the internal shaft core structure.

[0036] Furthermore, when the expansion key 6 protrudes and expands from the material feeding shaft 2, the elastic ring 7 can be spread apart between several expansion keys 6. When the piston 3 moves and resets under the action of the reset spring 4, the spread elastic ring 7 can contract inward, thereby driving the expansion component 6 to contract and reset inward. At this time, the material can fall off from the end of the material feeding shaft 2, completing the material feeding operation.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
