Description

Technical Field

[0001] This utility model relates to the field of classification rack technology, specifically a material arrival inspection classification rack. Background Technology

[0002] In the field of industrial production and materials management, the acceptance and storage management of round workpieces (such as nuts, bearings, and round gaskets) is a crucial step. Currently, ordinary shelves, storage boxes, or simple rod-shaped supports are commonly used for storing these round workpieces.

[0003] However, while ordinary shelves and storage boxes can achieve a certain degree of classified storage, if the workpieces are not handled properly during placement, they are prone to falling from a height and colliding rigidly with the shelves or boxes, resulting in wear, deformation, or even damage to the precision of the workpieces, affecting their quality and subsequent use.

[0004] Existing simple rod-shaped supports typically only serve to hold the workpiece in place, lacking an effective cushioning structure. When a circular workpiece is fitted into the support, it will fall directly to the bottom under gravity, and will be damaged due to rigid impact. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a material arrival inspection and classification rack.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A material receiving and sorting rack, comprising:

[0008] Base;

[0009] Multiple vertically arranged sorting rods are fixedly installed on the upper surface of the base for fitting circular workpieces.

[0010] Multiple axially extending vertical grooves are opened on the peripheral wall of each sorting rod and are evenly distributed in the circumferential direction.

[0011] Multiple elastic elements are arranged one-to-one in each of the vertical grooves, and the upper end of each elastic element is fixed to the top of the inner side of the vertical groove.

[0012] Wherein, the minimum distance between the lower ends of adjacent elastic elements is greater than the height of the circular workpiece;

[0013] In its natural state, the elastic element has an angle of 30°-90° between its free end and the axial direction of the sorting rod, and when the elastic element is pressed into the vertical groove by the circular workpiece, its outer surface is in clearance fit with the inner wall of the circular workpiece.

[0014] The maximum elastic force provided by the elastic element is less than the weight of the circular workpiece to be fitted.

[0015] Preferably, the end of the elastic element is provided with an arc-shaped block, and a groove is provided in the middle of the outer side of the arc-shaped block;

[0016] The elastic element is configured such that, after being squeezed by the circular workpiece, its final state is located inside the circular workpiece and is in a compressed state, while the arc-shaped block is in an expanded state.

[0017] Preferably, the rotation point of the elastic element is located inside the vertical groove, and when the circular workpiece passes over the elastic element, the elastic element deforms into the vertical groove.

[0018] Preferably, the thickness of the elastic element gradually decreases along its length.

[0019] Preferably, the depth of the vertical groove is greater than the thickness of the elastic element, and a deformation space is reserved between the bottom of the groove and the elastic element.

[0020] Preferably, in its natural state, the angle between the free end of the elastic element and the axial direction of the sorting rod is 45°-80°.

[0021] Preferably, the elastic element is a metal spring sheet or an elastic rubber strip with a rubber sleeve covering its surface.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. Effective protection of workpieces: Multiple elastic elements buffer and decelerate the falling circular workpieces, significantly reducing the falling speed and preventing rigid collisions with the sorting rack when the workpieces fall directly. This reduces damage to the workpieces caused by collisions and protects their precision and quality.

[0024] 2. Convenient and efficient to use: The workpiece only needs to be aligned with the top of the sorting rod and inserted. Under its own gravity, it will fall and be stored. The operation is simple and convenient, without complicated operation steps, saving manpower and time costs. Attached Figure Description

[0031] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0032] Example

[0033] like Figure 1-4 As shown, a material receiving and sorting rack includes:

[0034] Base 1: Serves as the supporting foundation for the entire sorting rack, providing a stable mounting platform for other components.

[0035] Multiple vertically arranged sorting rods 2 are fixedly installed on the upper surface of the base 1. Their main function is to fit round workpieces and realize the classification and storage of different round workpieces. The multiple vertically arranged sorting rods 2 can be set with different diameters to adapt to different types of round workpieces, such as nuts.

[0036] Multiple vertical slots 21 are formed on the peripheral wall of each sorting rod 2 and are evenly distributed along the circumference. The vertical slots 21 provide space for the installation and deformation of the elastic element 22.

[0037] Multiple elastic elements 22 are correspondingly disposed within each vertical groove 21, with their upper ends fixed to the inner top of the vertical groove 21. The thickness of the elastic element 22 gradually decreases along its length, and its rotation point is located inside the vertical groove 21. The elastic element 22 can be a metal spring sheet or an elastic rubber strip with a rubber sleeve covering its surface.

[0038] The minimum distance between the lower ends of adjacent elastic elements 22 is greater than the height of the circular workpiece, ensuring that the circular workpiece can pass smoothly.

[0039] In its natural state, the angle between the free end of the elastic element 22 and the axial direction of the sorting rod 2 is 30°-90°, preferably 45°-80°, to ensure that the elastic element 22 can be well deformed by collision with the circular workpiece.

[0040] When the elastic element 22 is pressed into the vertical groove 21 by the circular workpiece, its outer side is in clearance fit with the inner wall of the circular workpiece to ensure that the circular workpiece can fall smoothly.

[0041] The maximum elastic force provided by the elastic element 22 is less than the weight of the circular workpiece to be fitted, enabling the workpiece to overcome the elastic force and fall.

[0042] The depth of the vertical groove 21 is greater than the thickness of the elastic element 22, and a deformation space is reserved between the bottom of the groove and the elastic element 22 to provide sufficient space for the deformation of the elastic element 22.

[0043] The end of the elastic element 22 is provided with an arc-shaped block 221, which is made of elastic material, such as plastic or rubber. A groove 222 is provided in the middle of the outer side of the arc-shaped block 221. The final state of the elastic element 22 after being squeezed by the circular workpiece is as follows: the elastic element 22 is located inside the circular workpiece and is in a compressed state, while the arc-shaped block 221 is in an expanded state. At this time, when it is transported or moved, the elastic element 22 will give the circular workpiece an outward tension to prevent the inner wall of the circular workpiece from colliding or rubbing against the sorting rod 2. The arc-shaped block 221 in the expanded state will increase the tension area of ​​the sorting rod 2 on the inner wall of the circular workpiece to a certain extent, thereby improving stability. At the same time, the arc-shaped block 221 in the expanded state will give the circular workpiece a reaction force when it has a tendency to rotate, thereby preventing the circular workpiece from rotating and improving overall stability and protection.

[0044] When storing round workpieces (such as nuts), first select the sorting rod 2 with the corresponding diameter according to the workpiece model. After aligning the round workpiece with the top of the selected sorting rod 2 and inserting it, the workpiece will begin to fall under its own weight.

[0045] During the descent, since the free end of the elastic element 22 in its natural state has an angle of 30°-90° (preferably 45°-80°) with the axis of the sorting rod 2, it can be well deformed by the collision of the circular workpiece. The workpiece will first contact the uppermost elastic element 22 and compress it. Because the rotation point of the elastic element 22 is located inside the vertical groove 21, and the depth of the vertical groove 21 is greater than the thickness of the elastic element 22, a deformation space is reserved between the bottom of the groove and the elastic element 22. Under the compression, the elastic element 22 will deform into the vertical groove 21.

[0046] Meanwhile, the maximum elastic force provided by the elastic element 22 is less than the weight of the circular workpiece to be fitted, allowing the workpiece to overcome the elastic force and continue falling. When the elastic element 22 is pressed into contact with the vertical groove 21, its outer surface fits the inner wall of the circular workpiece with a clearance, ensuring that the workpiece can pass smoothly through the elastic element 22. Furthermore, because the minimum distance between the lower ends of adjacent elastic elements 22 is greater than the height of the circular workpiece, the workpiece can smoothly enter the effective range of the next elastic element 22.

[0047] Subsequently, the workpiece will interact in a similar manner with multiple elastic elements 22 below, each elastic element 22 playing a certain role in buffering and decelerating the workpiece during its descent. After being buffered by this series of elastic elements 22, the falling speed of the workpiece is greatly reduced, and it finally lands smoothly at the bottom of the sorting rod 2, avoiding rigid collisions when falling directly and effectively protecting the workpiece and the sorting rack.

[0048] Effective protection of workpieces: Multiple elastic elements 22 buffer and decelerate the falling circular workpieces, significantly reducing the falling speed of the workpieces and avoiding rigid collisions with the sorting rack when the workpieces fall directly. This reduces damage to the workpieces caused by collisions and protects the precision and quality of the workpieces.

[0049] Achieve categorized management: Multiple categorization rods of different diameters can be adapted to different models of round workpieces, enabling orderly categorization and storage of workpieces of different specifications. This facilitates quick identification and retrieval by staff during incoming inspection, improving work efficiency.

[0050] Good protection: When transported or moved, the elastic element 22 will give the circular workpiece an outward tension to prevent the inner wall of the circular workpiece from colliding or rubbing against the sorting rod 2. The arc block 221 in the expanded state will increase the tension area of ​​the sorting rod 2 on the inner wall of the circular workpiece to a certain extent, which will improve the stability. At the same time, the arc block 221 in the expanded state will give the circular workpiece a reaction force when it has a tendency to rotate, preventing the circular workpiece from rotating and improving the overall stability and protection.

[0051] Easy and efficient to use: The workpiece only needs to be aligned with the top of the sorting rod 2 and inserted. Under its own gravity, it can complete the falling and storage process. The operation is simple and convenient, without complicated operation steps, saving manpower and time costs.

[0052] The structure is reasonably designed: the thickness of the elastic element 22 gradually decreases along the length direction, the rotation point is located inside the vertical groove 21, and the depth of the vertical groove 21 and the reserved deformation space are designed to ensure that the elastic element 22 can deform smoothly without affecting the falling of the workpiece. At the same time, the elastic element 22 adopts a metal spring sheet or elastic rubber strip with a rubber sleeve on the surface, which has both good elasticity and durability, and extends the service life of the sorting rack.

[0053] Easy to maintain: The simple structure of each component makes it easy to inspect and maintain. When the elastic element 22 and other components have problems, they can be easily replaced and repaired, reducing the difficulty and cost of maintenance.

[0054] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
