Description

Technical Field

[0001] This utility model relates to the technical field of jigs, and more specifically, to a hollow open shaft feeding device. Background Technology

[0002] In assembly production processes, hollow open shafts are often used as key components in various component transmission scenarios. However, their unique hollow and side-opening design also presents challenges to production efficiency in the material loading process.

[0003] Due to the hollow and open design of the hollow open shaft, when multiple hollow open shafts are stacked together, or during stacking and conveying, their shaft cavities and side openings will interlock and entangle with each other, resulting in a nesting phenomenon. This means that in the initial stage of feeding, time and manpower are required to arrange the hollow open shafts to put them in an orderly state suitable for feeding, thereby reducing feeding efficiency.

[0004] In addition, most existing general-purpose feeding equipment cannot accurately push a single hollow open shaft, resulting in the feeding of multiple hollow open shafts at one time. It is impossible to separate the hollow open shafts that are nested with each other, making it difficult to adapt to subsequent processing or assembly stations. This not only reduces the success rate of feeding but also reduces the overall production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a hollow open shaft feeding device, which aims to solve the problem of low feeding efficiency of hollow open shafts in the prior art.

[0006] This invention is implemented as follows: a hollow open shaft feeding device includes a guide channel in the shape of a straight strip that can only accommodate a single hollow open shaft and a push shaft. The top of the guide channel is open to form a top opening for the hollow open shaft to be fed. The front end of the guide channel is through to form an insertion port for the push shaft to be inserted. The rear end of the guide channel is through to form a push port for the hollow open shaft to be disengaged from the guide channel. The hollow open shaft is surrounded by a shaft cavity, and the side of the hollow open shaft has a through side opening. The hollow open shaft falls into the guide channel through the top opening, and the push shaft is inserted into the guide channel through the insertion port, abutting against the end of the hollow open shaft. The push shaft moves toward the ejection port, ejecting the single hollow open shaft in the guide channel from the guide channel.

[0007] Furthermore, the bottom of the guide channel has a bottom wall, and the longitudinal section of the bottom wall is arc-shaped.

[0008] Furthermore, the height of the guide channel is less than the radius of the hollow open shaft, and the diameter of the guide channel is greater than the diameter of the hollow open shaft. When the hollow open shaft is placed in the guide channel, the hollow open shaft is in a movable arrangement.

[0009] Furthermore, a buffer channel is provided above the guide channel, and the buffer channel can only accommodate a single hollow open shaft along the width direction of the buffer channel; the buffer channel extends in the same direction as the guide channel, and the buffer channel communicates with the top opening.

[0010] Furthermore, the width of the buffer channel is the same as the width of the top opening.

[0011] Furthermore, the buffer channels are arranged with equal diameters along the height direction of the buffer channel.

[0012] Furthermore, the top of the buffer channel is open, forming an open material discharge chamber. The bottom of the material discharge chamber is connected to the buffer channel, and the top of the material discharge chamber has a discharge port for a hollow open shaft to enter the material discharge chamber.

[0013] Furthermore, the width of the material discharge chamber gradually increases from bottom to top along the direction of the discharge chamber.

[0014] Furthermore, the push shaft has a push section for inserting into the guide channel, and the height of the push section is less than the radius of the hollow open shaft.

[0015] Furthermore, the bottom of the pushing section has a bottom arc surface, the top of the pushing section has a flat top plane, and the diameter of the bottom arc surface is smaller than the diameter of the guide channel.

[0016] Compared with the prior art, the hollow hinge shaft feeding device provided by this utility model adopts a guide channel that is straight and can only accommodate a single hollow open shaft, so that the hollow open shaft can fall into the open opening at the top of the guide channel in an orderly manner and be arranged in sequence in the guide channel. The insertion port at the front end of the guide rail provides a position for the push shaft to be inserted, while the ejection port at the rear end ensures that the hollow open shaft can be smoothly ejected from the guide rail.

[0017] When the push shaft is inserted into the insertion port, it can abut against the end of the hollow open shaft. As the push shaft moves toward the ejection port, a single hollow open shaft can be stably ejected from the guide channel. This process avoids multiple hollow open shafts from nesting and tangling with each other, thereby improving the orderliness and success rate of feeding and achieving a substantial improvement in the feeding efficiency of hollow open shafts.

[0022] Reference Figure 1-6 The image shown is a preferred embodiment of the present invention.

[0023] A hollow open shaft feeding device includes a guide channel 200 in the shape of a straight strip that can only accommodate a single hollow open shaft 100 and a push shaft 300. The top of the guide channel 200 is open, forming a top opening 201 for the hollow open shaft 100 to be fed out. The front end of the guide channel 200 is through, forming an insertion port 202 for the push shaft 300 to be inserted. The rear end of the guide channel 200 is through, forming an ejection port 203 for the hollow open shaft 100 to be disengaged from the guide channel 200. The hollow open shaft 100 is surrounded by a shaft cavity 101, and the side of the hollow open shaft 100 has a through side opening 102. The hollow open shaft 100 falls into the guide channel 200 through the top opening 201. The push shaft 300 is inserted into the guide channel 200 through the insertion port 202 and abuts against the end of the hollow open shaft 100. The push shaft 300 moves toward the ejection port 203 to eject the hollow open shaft 100 from the guide channel 200.

[0024] The hollow open shaft feeding device provided above uses a guide channel 200 that is straight and can only accommodate a single hollow open shaft 100, so that the hollow open shaft 100 can fall into the open opening at the top of the guide channel 200 in an orderly manner and be arranged sequentially in the guide channel 200. The insertion port 202 at the front end of the guide channel 200 provides a position for the push shaft 300 to be inserted, while the ejection port 203 at the rear end ensures that the hollow open shaft 100 can be smoothly ejected from the guide channel 200.

[0025] When the push shaft 300 is inserted into the insertion port 202, it can abut against the end of the hollow open shaft 100. As the push shaft 300 moves toward the ejection port 203, a single hollow open shaft 100 can be stably ejected from the guide channel 200. This process avoids multiple hollow open shafts 100 from nesting and tangling with each other, thereby improving the orderliness and success rate of feeding and achieving a substantial improvement in the feeding efficiency of the hollow open shaft 100.

[0026] The hollow open shaft 100 mentioned in this embodiment is mainly used to connect two components (elements). The two components are provided with mutually aligned holes. The hollow open shaft 100 is inserted into the holes as a hinge to realize the connection between the components. The hollow and open design of the hollow open shaft 100 gives the hinge greater elastic space and assembly flexibility, and can better adapt to holes with different small deformations.

[0027] In this embodiment, the bottom of the guide channel 200 has a bottom wall 204, and the longitudinal section of the bottom wall 204 is arc-shaped; in this way, it can fit the outer contour of the hollow open shaft 100. When the shaft falls into the guide channel 200, the arc-shaped bottom wall 204 can evenly distribute the weight of the hollow open shaft 100, reduce local pressure, and prevent the shaft from tilting or getting stuck due to unstable placement. During the pushing process of the pusher shaft 300, the hollow open shaft 100 needs to be quickly and accurately conveyed to the next process. The arc-shaped bottom wall 204 can reduce the coefficient of friction with the bottom of the guide channel 200, ensuring that the hollow open shaft 100 moves stably and smoothly along the guide channel 200, reducing conveying failures caused by shaft shaking or jamming, and ensuring the continuity and efficiency of the production line.

[0028] In this embodiment, the height of the guide channel 200 is less than the radius of the hollow open shaft 100, and the diameter of the guide channel 200 is greater than the diameter of the hollow open shaft 100. When the hollow open shaft 100 is placed in the guide channel 200, the hollow open shaft 100 is in a movable arrangement.

[0029] In this way, the radius of the hollow open shaft 100 is greater than the height of the guide channel 200, ensuring that the shaft will not sink excessively within the guide channel 200 and maintain a relatively stable posture; the diameter of the guide channel 200 is greater than the diameter of the shaft, which neither hinders the hollow open shaft 100 from smoothly entering the guide channel 200, nor prevents it from slightly adjusting its position within the guide channel 200. When multiple hollow open shafts 100 are arranged sequentially in the guide channel 200, the slight collision and displacement adjustment between the upper hollow open shaft 100 and the lower hollow open shaft 100 will not cause the shaft to jam or block. On the contrary, the mobility of the hollow open shafts 100 makes the downward pressure more evenly transmitted, causing the hollow open shafts 100 to move towards the push-out port 203 in an orderly manner. Especially in the case of large-volume feeding, it can improve the feeding smoothness and success rate.

[0030] In this embodiment, a buffer channel 205 is provided above the guide channel 200. Along the width direction of the buffer channel 205, the buffer channel 205 can only accommodate a single hollow open shaft 100. The buffer channel 205 extends in the same direction as the guide channel 200 and is connected to the top opening 201.

[0031] The buffer channel 205 is set to be wide enough to accommodate only a single hollow open shaft 100, ensuring that only one shaft can enter the guide channel 200 in an orderly manner, thus avoiding the chaos of multiple shafts entering at the same time and causing them to become entangled and nested.

[0032] The buffer channel 205 and the guide channel 200 extend in the same direction and are connected to the top opening 201, thus forming a continuous feeding channel. After the hollow open shaft 100 enters from the top opening 201, it first briefly organizes its queue in the buffer channel 205, and then smoothly transitions to the guide channel 200, laying the foundation for subsequent pushing. This improves the overall efficiency and stability of feeding and is a key structural improvement for optimizing the feeding process.

[0033] In this embodiment, the width of the buffer channel 205 is the same as the width of the top opening 201; in this way, when the hollow opening shaft 100 falls to the top opening 201, it can seamlessly and smoothly transition to the buffer channel 205 without having to adapt to additional width changes, reducing the risk of shaft offset and jamming caused by mismatch in entrance width.

[0034] In actual production, the hollow open shafts 100 are stacked in the feeding chamber 206 to the top opening 201. The consistent width ensures that the hollow open shafts 100 enter the buffer channel 205 stably, maintain the continuity of feeding, and ensure feeding efficiency.

[0035] In this embodiment, the buffer channel 205 is arranged with a uniform diameter along the height direction of the buffer channel 205. In this way, the hollow open shaft 100 is subjected to balanced force within the buffer channel 205. Regardless of its height position in the buffer channel 205, the uniform diameter of the buffer channel 205 can ensure that the hollow open shaft 100 slides down smoothly and at a uniform speed to the entrance of the guide channel 200. Through a uniform feeding speed and rhythm, it prevents accumulation or blockage caused by changes in the shape of the buffer channel 205, and ensures the smoothness and efficiency of the feeding process.

[0036] In this embodiment, the top of the buffer channel 205 is open, forming an open material discharge cavity 206. The bottom of the material discharge cavity 206 is connected to the buffer channel 205, and the top of the material discharge cavity 206 has a discharge port for the hollow open shaft 100 to enter the material discharge cavity 206.

[0037] The open top feeding port allows the hollow open shaft 100 to enter from different angles and positions above, expanding the feeding inlet range and increasing feeding flexibility.

[0038] The bottom of the material discharge chamber 206 is connected to the buffer channel 205, allowing the hollow open shaft 100 to slide naturally and smoothly from the material discharge chamber 206 into the buffer channel 205 under the action of gravity, without the need for complicated auxiliary devices to guide it. This improves the accuracy and efficiency of feeding, simplifies the feeding process, and reduces production costs.

[0039] In this embodiment, the width of the material discharge cavity 206 gradually increases from bottom to top along the direction of the material discharge cavity 206; when the buffer channel 205 below continuously receives the hollow open shaft 100, the gradually expanding material discharge cavity 206 above can effectively receive the hollow open shaft 100 falling from different directions and at different speeds, gradually gather them and guide them to the entrance of the buffer channel 205.

[0040] This gradual widening allows the gradually widening discharge chamber 206 to easily handle the convergence demand of the hollow open shafts 100 when dealing with multiple sources and non-directional supply, maintaining the efficiency and reliability of feeding.

[0041] In this embodiment, the push shaft 300 has a push section 301 for inserting into the guide channel 200. The height of the push section 301 is less than the radius of the hollow open shaft 100. This ensures that the push shaft 300 can be accurately and deeply inserted into the guide channel 200 and fit against the end of the hollow open shaft 100. Moreover, it also means that the area of ​​the push section 301 is half that of the push shaft 300, and it is crescent-shaped.

[0042] During the pushing process, the high adaptability of the pushing section 301 ensures the accuracy and stability of the pushing action. Even if the two hollow open shafts 100 are nested in the guide channel 200, the pushing section 301 can push the single hollow open shaft 100 smoothly out of the guide channel 200 by only contacting part of the end face of the single hollow open shaft 100, thereby improving the accuracy and efficiency of feeding.

[0043] In this embodiment, the bottom of the pusher section 301 has a bottom arc surface 302, the top of the pusher section 301 has a flat top plane 303, and the diameter of the bottom arc surface 302 is smaller than the diameter of the guide channel 200.

[0044] Among them, the bottom arc surface 302 can easily slide over the bottom of the guide channel 200 when the push shaft 300 is inserted into the guide channel 200, reducing insertion resistance and quickly reaching the end of the hollow open shaft; while the top plane 303 provides a flat and uniform thrust contact surface when it contacts the end of the hollow open shaft, ensuring the effective transmission of thrust.

[0045] In addition, the diameter of the bottom arc surface 302 is smaller than the diameter of the guide channel 200, which further reduces the risk of interference between the push shaft 300 and the guide channel 200. In the case of frequent feeding, the push shaft 300 needs to push the hollow open shaft 100 back and forth continuously. The fact that the diameter of the bottom arc surface 302 is smaller than the diameter of the guide channel 200 can ensure that each pushing action is efficient and accurate, thus improving the feeding efficiency.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
