Description

Technical Field

[0001] This utility model relates to the field of automated parts feeding equipment, and in particular to a general-purpose parts feeding device. Background Technology

[0002] When loading materials onto machine tools such as lathes, the variety of parts that lathes can process, and the significant differences in shape characteristics among different types of parts, necessitates changing different types of pallets and tooling fixtures to ensure the parts can be accommodated and positioned. However, this method requires a large number of tooling fixtures, resulting in high equipment costs, and each change incurs additional time and labor costs, impacting processing efficiency and overall cost. Utility Model Content

[0003] The present invention aims to solve the above problems and provides a general-purpose parts feeding device, the technical solution of which is as follows: A general-purpose parts loading device includes a loading rack, a loading drive wheel, a loading conveyor belt, a tooling pallet, and a positioning mechanism. The loading conveyor belt moves horizontally from a placement position to a positioning position on the loading rack. The loading conveyor belts are arranged in pairs parallel to each other and move synchronously in the same horizontal plane. The tooling pallet is placed on the loading conveyor belt at the placement position and overlaps with the two loading conveyor belts. The tooling pallet is used to place the parts to be loaded. The positioning mechanism is set at the positioning position and is arranged in pairs on both sides of the conveying direction of the loading conveyor belt.

[0004] Based on the above scheme, the bottom of the tooling pallet is fixedly connected to the pallet support legs, the pallet support legs extend downwards, and the bottom overlaps the feeding conveyor belt.

[0005] Based on the above scheme, the positioning mechanism includes a positioning clamping motor and a positioning clamping plate. The clamping motor is fixedly connected to the feeding rack and is arranged in a horizontal direction. The positioning clamping plate is fixedly connected to the movable part of the clamping motor and moves in a direction perpendicular to the feeding conveyor belt in the horizontal plane. The positioning clamping plate moves inward to the clamping position and moves outward to the releasing position. A guide block is fixedly connected to the side of the positioning clamping plate facing the tooling pallet. The outer side of the guide block forms a positioning groove in the horizontal plane. When the positioning clamping plate moves to the clamping position, the pallet support legs are engaged in the positioning groove. When the positioning clamping plate moves to the releasing position, the pallet support legs are released from the positioning groove.

[0006] Based on the above scheme, there are multiple guide blocks, which are arranged in parallel along the direction of movement of the feeding conveyor belt in the horizontal plane. The positioning groove is located between adjacent guide blocks and outside the outer edge of the outermost guide block.

[0007] Based on the above scheme, a transition edge is provided on the outer edge of the guide block near the tooling pallet, and the transition edge is arc-shaped.

[0008] Preferably, the tooling pallet has a planar structure with its edges protruding upwards to form a surrounding edge.

[0009] Preferably, it further includes a centering mechanism, which is set at the positioning position and includes a centering frame, a horizontal moving mechanism, a vertical moving mechanism, a centering mounting frame, a centering drive motor, and clamping rods. The centering frame is fixedly connected to the feeding frame. The horizontal moving mechanism is fixedly mounted on the centering frame in the horizontal direction. The vertical moving mechanism is set in the vertical direction and moves in the horizontal direction on the horizontal moving mechanism. The centering mounting frame is slidably set on the vertical moving mechanism. There are three clamping rods, which are symmetrically arranged about the axis center of the centering mounting frame. The centering drive motor drives the three clamping rods to synchronously move closer to or away from the axis center.

[0010] Preferably, the feeding rack is further provided with a feeding motor, which drives the feeding drive wheel to rotate, and the feeding conveyor belt is sleeved on the feeding drive wheel.

[0011] Preferably, the number of tooling pallets is multiple.

[0012] The beneficial effects of this utility model are as follows: the flat tooling pallet can accommodate most parts to be processed, eliminating the need to prepare multiple pallets based on the shape and size characteristics of the parts, and eliminating the need to change tooling according to different parts during loading, thus reducing equipment costs and the time cost required for replacement; the tooling pallet moves with the loading conveyor belt in an overlapping manner, making the loading action flexible and easy to operate; the positioning mechanism clamps and positions the tooling pallet, accurately determining the relative positional relationship between the tooling pallet and the loading conveyor belt, maintaining loading accuracy; and the centering mechanism centers each part on the tooling pallet individually, ensuring the accuracy of the loading position of each part.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments: In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0015] In the description of this utility model, it should be understood that the terms "center," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," and "inner," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0016] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0017] like Figure 1As shown, a general-purpose parts loading device includes a loading rack 11, a loading drive wheel 14, a loading conveyor belt 12, a tooling pallet 15, and a positioning mechanism. The loading rack 11 is also equipped with a loading motor 13, which drives the loading drive wheel 14 to rotate. The loading conveyor belt 12 is sleeved on the loading drive wheel 14 and moves horizontally from the placement position to the positioning position on the loading rack 11. The loading conveyor belts 12 are arranged in pairs, parallel to each other, and move synchronously within the same horizontal plane. The tooling pallet 15 is placed on the loading conveyor belt 12 at the placement position, and simultaneously overlaps with two loading conveyor belts 12. The tooling pallet 15 is used to place the parts to be loaded. Preferably, the bottom of the tooling pallet 15 is fixedly connected to the pallet support leg 151, which extends downward and overlaps the bottom of the loading conveyor belt 12. The pallet support leg 151 raises the supporting surface of the tooling pallet 15, providing operating space for the transfer mechanism during subsequent transfer of the tooling pallet 15. The tooling pallet 15 has a planar structure. When placing cylindrical or conical workpieces to be processed, the end plane can be placed on the planar surface of the tooling pallet 15, and the edge protrudes upward to form a rim to prevent the workpiece from tilting and rolling off. Preferably, there are multiple tooling pallets 15, which facilitates the continuous placement of a large number of parts.

[0018] The positioning mechanism is located at the positioning position and is installed in pairs on both sides of the feeding conveyor belt 12 in the conveying direction. For example... Figure 1 and Figure 2As shown, the positioning mechanism includes a positioning clamping motor 16 and a positioning clamping plate 17. The clamping motor 16 is fixedly connected to the loading rack 11 and is arranged in a horizontal direction. The positioning clamping plate 17 is fixedly connected to the movable part of the clamping motor 16 and moves in the horizontal plane in a direction perpendicular to the loading conveyor belt 12. The positioning clamping plate 17 moves inward to the clamping position and outward to the releasing position. The positioning clamping plate 17 is fixedly connected to a guide block 171 on the side facing the tooling tray 15. The outer side of the guide block 171 forms a positioning groove 173 in the horizontal plane. There are multiple guide blocks 171, which are arranged in parallel in the horizontal plane along the direction of movement of the loading conveyor belt 12. The positioning groove 173 is located between adjacent guide blocks 171 and on the outer edge of the outermost guide block 171. When the positioning clamping plate 17 moves to the clamping position, the pallet support 151 engages in the positioning groove 173 to determine the relative position of the tooling pallet 15 and the feeding conveyor belt 12. During engagement, positioning can be achieved through the positioning groove 173 between adjacent guide blocks 171, or through the outer edge of the outermost guide block 171. The positioning groove 173 used for positioning can be adjusted according to the size of the tooling pallet 17 and the position of the positioning point. When the positioning clamping plate 17 moves to the releasing position, the pallet support 151 disengages from the positioning groove 173. Preferably, a transition edge 172 is provided on the outer edge of the guide block 171 near the tooling pallet 15. The transition edge 172 is arc-shaped, thus providing a clamping and guiding function, compensating for positional errors when the tooling pallet 15 is placed, and reducing the precision requirements and operational difficulty during mechanical or manual operation.

[0019] The relative positions of the tooling pallet 15 and the feeding conveyor belt 12 are fixed by a positioning mechanism, but the position of each part to be processed also needs to be fixed individually during the feeding process. The parts can be fixed manually in advance on the tooling pallet 15 to fix the relative positions of the parts and the pallet, or a centering mechanism can be used to position the parts individually.

[0020] The centering mechanism used in this embodiment is set at the positioning position and includes a centering frame 21, a horizontal moving mechanism 22, a vertical moving mechanism 23, a centering mounting frame 24, a centering drive motor 251, and clamping rods 28. The centering frame 21 is fixedly connected to the feeding frame 11. The horizontal moving mechanism 22 is fixedly mounted on the centering frame 21 in the horizontal direction. The vertical moving mechanism 23 is set in the vertical direction and moves in the horizontal direction on the horizontal moving mechanism 22. The centering mounting frame 24 is slidably set on the vertical moving mechanism 23. There are 3 clamping rods 28, which are symmetrically arranged about the axis center of the centering mounting frame 24. The centering drive motor 251 drives the 3 clamping rods 28 to move synchronously closer to or further away from the axis center. Preferably, the centering drive motor 251 can be coaxially connected to a drive gear, which simultaneously meshes with three driven gears. Three clamping rods 28 are eccentrically connected to one driven gear. The movement of the drive gear drives the three driven gears and the clamping rods 28 to rotate and move synchronously, thereby calibrating the position of cylindrical or conical parts through the relative inward movement of the clamping rods 28. In conjunction with the movements of the horizontal moving mechanism 22 and the vertical moving mechanism 23, the centering mounting frame 24 moves horizontally and vertically, thus achieving centering of parts at different positions and heights.

[0021] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
