Description

Technical Field

[0001] This utility model relates to a parts storage and transfer device, specifically to a flat support structure for gear parts and a parts basket. Background Technology

[0002] In manufacturing, gear parts are typically stored and transported in parts baskets on European standard (800mm × 1200mm) or Japanese standard (1100mm × 1100mm) pallets. These baskets are usually made of pure steel, or a combination of metal materials and plastic supports. The metal materials are typically ordinary steel bars and angle iron with painted or galvanized surfaces, while the plastic supports are made of polyethylene or nylon. Gear parts are usually placed either horizontally or vertically within the baskets.

[0003] If gear parts are stored flat in a pure steel parts basket, the basket becomes too heavy, the handling work becomes strenuous, and the gear parts are prone to collisions. Gear parts can be placed upright or flat in a parts basket combining steel reinforcement and plastic supports, reducing the basket's weight. However, the plastic supports are relatively soft, and the gears can wear down the supports, reducing the basket's lifespan. Furthermore, plastic residue on the gear parts can easily affect their surface finish. Alternatively, gear parts can be stored in hanging racks, which allow for upright placement. This method makes it difficult to maintain a stable position for the gear parts and integrates well with automated production lines. Currently, there is no optimal structural design that simultaneously balances parts protection, basket lifespan, and suitability for automated production lines.

[0004] Chinese patent CN203956902U discloses a workstation fixture for a quasi-hypoid gear, including a workstation frame, a directional wheel, a steering wheel, and a ground brake mounted on the bottom surface of the workstation frame, and a gear tray mounted inside the workstation frame; the gear tray is equipped with a protective device. However, the shortcomings of this patent are: the high density of gear parts makes them prone to collision, and it is difficult to adapt to automated production lines.

[0005] Chinese patent CN203956902U relates to the field of coal mining machinery manufacturing, specifically a flexible protective workstation frame for bevel gears in mining reducers. It comprises a main frame composed of channel steels a, b, c, d, and e. Through holes are provided at corresponding positions on the main frame, and support rods are inserted into these holes, with rubber sleeves installed on the support rods. Channel steels f and g are welded to the main frame to form a 120° "V"-shaped support, with a rubber block fixed to channel steel g. When workpieces are stacked, the bevel gear teeth rest on the "V"-shaped rubber block. After the workpiece falls, the two sets of support rods completely hold the workpiece in place, ensuring a completely flexible contact between the workstation frame and the workpiece, preventing scratches and slippage. However, this patent has drawbacks: it is heavy, difficult to transport, and unsuitable for use in automated production lines. Utility Model Content

[0006] The purpose of this invention is to solve the problems of existing devices for storing and transporting gear parts, such as easy collision between parts, difficulty in handling, difficulty in adapting to automated production lines, and short service life. The invention provides a flat support structure and parts basket for gear parts.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] A flat support structure for gear-like parts, characterized by:

[0009] The device includes a Y-shaped limiting block, three gear end face support limiting posts connected at one end to the lower part of the outer end face of the three extended arms of the Y-shaped limiting block, gear outer circle limiting blocks respectively disposed at the other end of each gear end face support limiting post, and a metal strip embedded on the upper side of the gear end face support limiting post, with both ends embedded in the corresponding gear outer circle limiting block and Y-shaped limiting block; the Y-shaped limiting block, each gear end face support limiting post, and each gear outer circle limiting block are all made of plastic; the included angle between the vertical midpoints of two adjacent extended arms in the Y-shaped limiting block is 120°; the bottom surfaces of the Y-shaped limiting block, gear end face support limiting post, and gear outer circle limiting block are flush.

[0010] Furthermore, the cross-section of the metal strip is circular, and its cross-sectional radius is defined as R3. The height of the portion embedded in the upper side of the gear end face support and limiting post is 1 / 2 to 2 / 3 of the cross-sectional diameter 2R3 of the metal strip. The upper end of the gear end face support and limiting post is provided with a 45° inclined drainage surface on both sides of the metal strip.

[0011] Furthermore, in the Y-shaped limiting block, the transition between two adjacent extended arms is achieved by a first rounded corner, and the upper surface of the three extended arms is provided with a guide chamfer surface between it and the side of the corresponding gear outer circle limiting block; the upper end of each gear outer circle limiting block has an inner guide slope on the side near the Y-shaped limiting block and an outer guide slope on the side away from the Y-shaped limiting block.

[0012] Furthermore, the height L1 of the outer guide slope is greater than the height L2 of the inner guide slope.

[0013] Furthermore, let the height of the gear outer circle limiting block be h1, the thickness be Z, and the top thickness be Z1; then: h1 / 3 <L1≤h1 / 2,h1 / 4≤L2≤h1 / 3;Z / 4≤Z1≤Z / 2。

[0014] Furthermore, each of the support and limiting columns has four square hollow weight-reducing grooves at its bottom along the axial direction.

[0015] Furthermore, each of the metal strips is made of 304 stainless steel;

[0016] The Y-shaped limiting block, the end face support limiting post of each gear, and the outer circle limiting block of each gear are all made of polyurethane.

[0017] Furthermore, the cross-sectional radius of the metal strip is R3 = 1.5 mm, and the two inclined drainage surfaces and the upper surface of the gear end face support limiting post are both transitioned by a second rounded corner with a curvature radius of R4 = 3 mm.

[0018] The height h1 of the gear outer circle limiting block is 56mm, the inner guide slope is a curved surface with a radius of curvature R1 = 120mm, and the angle between the line connecting the two ends of the longitudinal axis of symmetry of the curved surface and any plane perpendicular to the bottom surface of the gear outer circle limiting block is 15°.

[0019] Furthermore, the height h7 of the Y-shaped limiting block is 31mm, the radius of curvature R7 of the first fillet is 11mm, the radius of curvature R6 of the three guide chamfer surfaces is 25mm, and the upper surface of the Y-shaped limiting block and the side surfaces between the two adjacent guide chamfer surfaces are transitioned by a third fillet with a radius of curvature R8 = 3.5mm.

[0020] Meanwhile, this utility model also provides a parts basket, including a base plate and baffles vertically arranged around the base plate, which is special in that:

[0021] The base plate is provided with several of the aforementioned gear-like parts laid flat as support structures.

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

[0023] 1. The gear-type parts flat support structure provided by this utility model has three gear outer circle limiting blocks that can uniformly limit the addendum circle of the gear-type parts in three directions. While being compatible with gear-type parts of various outer diameters, it can also control the posture and position of the gear-type parts within a specific field of view and expose key features from a top-down view, which can facilitate visual picking by operators or robots. The Y-shaped limiting block is used to limit the inner diameter of the gear-type parts, so that gear-type parts with an inner diameter greater than a certain value can be stably loaded on the Y-shaped limiting block, which can reduce damage to gear-type parts and reduce the working difficulty of operators or robots. In this utility model, all components except the metal strip are made of plastic. Without significantly affecting the service life, it can greatly reduce the overall weight, which is beneficial for operators to handle.

[0024] 2. The gear-type parts flat support structure provided by this utility model is equipped with an inner guide slope and three guide chamfered surfaces, which can effectively prevent the robot arm from placing the gear-type parts unevenly when there is a positioning deviation. Moreover, both the inner and outer guide slopes have the effect of reducing weight and saving processing materials. At the same time, the multiple hollow weight-reducing grooves also have this effect. The height L1 of the outer guide slope is greater than the height L2 of the inner guide slope, which not only facilitates the demolding of this utility model during molding, but also reduces the probability of collision with other components during assembly, thereby improving safety.

[0025] 3. The flat support structure for gear parts provided by this utility model has a height of 1 / 2 to 2 / 3 of the diameter 2R3 of the metal strip embedded in the upper side of the support and limiting post on the end face of the gear. This ensures stable support for the gear parts and prevents the metal strip from falling off.

[0026] 4. The flat support structure for gear parts provided by this utility model, including the Y-shaped limiting block, the end face support limiting post of each gear, and the outer circle limiting block of each gear, are all made of polyurethane. Compared with traditional nylon materials, polyurethane has advantages in mechanical properties such as wear resistance and impact resistance. During use, this structure can effectively protect gear parts. Moreover, polyurethane has high surface hardness, so even if the body wears down due to long-term loading, there will be no shedding or flaking, which can greatly improve the overall cleanliness of gear parts and facilitate other process steps. At the same time, polyurethane has a long service life and is not easy to age and deform, which greatly reduces the risk of failure of the support and limiting function of the structure for gear parts. Polyurethane is easy to process and can be heated and extruded like PVC (Polyvinyl chloride) or PE (Polyethylene) without vulcanization, has good formability, and has relatively low manufacturing cost.

[0027] 5. The flat support structure for gear parts provided by this utility model has 304 stainless steel for each metal strip, which can provide safe and effective support for gear parts. The cross-section of the metal strip is circular, and its direct contact with the end face of the gear parts will not damage the gear parts.

[0028] 6. The flat support structure for gear parts provided by this utility model adopts a form of polyurethane embedded in 304 stainless steel metal strips. After the parts basket and gear parts are cleaned together, the large contact area between the gear parts and the air can improve the drying efficiency and reduce the corrosion of the gear parts.

[0029] 7. The parts basket provided by this utility model has several of the above-mentioned gear parts flat support structures set on the bottom plate inside. If it is used in the scenario where the operator manually moves the parts basket, it not only reduces the labor intensity of the operator, but also greatly improves the service life of the gear parts, the flat support structure of the gear parts, as well as the cleanliness and safety of the gear parts. Moreover, it is also suitable for automated production lines, which makes it easier for the robot to accurately grasp the gear parts and avoid grasping the wrong parts or damaging the gear parts.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

The three gear outer circle limiting blocks 1 can uniformly limit the addendum circle of gear parts in three directions. While being compatible with gear parts of various outer diameters, they can also control the posture and position of gear parts within a specific field of view and expose key features from a top-down perspective, which can facilitate visual picking by operators or robots. The Y-shaped limiting block 7 is used to limit the inner diameter of gear parts, so that gear parts with an inner diameter greater than a certain value can be stably loaded on the Y-shaped limiting block, which can reduce damage to gear parts and reduce the working difficulty of operators or robots.

[0037] The metal strip 3 has a circular cross-section with a radius of R3. The portion embedded within the upper side of the gear end face support post 5 has a height equal to 2 / 3 of the metal strip 3's cross-sectional diameter 2R3, ensuring stable support for gear-like parts while preventing the metal strip from detaching. The upper end of the gear end face support post 5 has 45° inclined drainage surfaces 4 on both sides of the metal strip 3, allowing cleaning fluid to drain smoothly and preventing water accumulation. The cross-sectional radius of the metal strip 3 is R3 = 1.5 mm, and the two inclined drainage surfaces 4 transition to the upper surface of the gear end face support post 5 using a second rounded corner with a curvature radius R4 = 3 mm. Each support post 5 has four square, hollowed-out weight-reducing grooves 8 along the axial direction on its bottom surface, reducing weight and manufacturing costs.

[0038] Each metal strip 3 is made of 304 stainless steel, which has high strength and can effectively support gear parts. The Y-shaped limiting block 7, the end face support limiting post 5 of each gear, and the outer circle limiting block 1 of each gear are all made of polyurethane. Compared with traditional nylon materials, polyurethane has advantages in mechanical properties such as wear resistance and impact resistance. During use, this structure can effectively protect gear parts; moreover, polyurethane has high surface hardness, so even if the body wears down after long-term loading, there will be no shedding or flaking, which can greatly improve the overall cleanliness of gear parts and facilitate other processes; at the same time, polyurethane has a long service life and is not easy to age and deform, which greatly reduces the risk of failure of the structure's support and limiting function for gear parts; polyurethane is easy to process and can be heat-extruded like PVC (Polyvinyl chloride) or PE (Polyethylene) without vulcanization, has good formability, and has relatively low manufacturing cost.

[0039] To facilitate demolding during molding and reduce the probability of collision with other components during assembly, thereby improving safety, the height L1 of the outer guide slope in this embodiment is greater than the height L2 of the inner guide slope 2; the height of the gear outer circle limiting block 1 is defined as h1, the thickness as Z, and the top thickness as Z1; then: L1 = h1 / 2, L2 = h1 / 4; Z1 = Z / 4.

[0040] Meanwhile, this utility model embodiment also provides a parts basket, including a base plate and baffles vertically arranged around the base plate, and the base plate is provided with a plurality of the above-mentioned gear-type parts flat support structures.

[0041] It should be noted that the above is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the scope of the specific embodiments disclosed in the present utility model. For example, the parameters of components such as the gear outer circle limiting block 1, the gear end face support limiting column 5, and the Y-shaped limiting block 7 can be changed to adapt to gear parts of different sizes or models. All such modifications or substitutions should be covered within the protection scope of the present utility model.
