Description

Technical Field

[0001] This utility model relates to the field of bar stock feeding technology, and in particular to a bar stock feeding device. Background Technology

[0002] Friction stir additive manufacturing is an advanced technology for solid additive manufacturing that utilizes the principle of friction stir welding. Its basic process involves forcibly inserting a high-speed rotating stirring head with enormous axial pressure into multiple layers of metal sheets or stacked metal foils. The intense friction generates localized plastic deformation and softening. During the movement of the stirring head, the softened material is violently stirred and mixed along a specific flow channel, and then cooled to form a dense and firmly bonded new layer. In existing friction stir additive manufacturing processes, robotic arms are commonly used for feeding rods. However, when using robotic arms, the rods are usually piled up together and then removed by the robotic arm. The rods accumulate and rub against each other in the hopper, which can easily cause scratches, indentations, or damage to the coating on the surface. At the same time, material blockage may occur, making it inconvenient for the robotic arm to pick them up, which cannot meet the needs of the operators. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bar stock feeding device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A bar stock feeding device includes a base, a support frame fixedly mounted on the base, a placement box fixedly mounted on the support frame, a limit block fixedly mounted on the placement box, two support frames fixedly mounted on the base, a rotary motor fixedly mounted on one of the support frames, a rotating shaft fixedly mounted on the output shaft of the rotary motor, two connecting blocks fixedly mounted on the rotating shaft, a telescopic block slidably connected to the connecting blocks, a spring fixedly mounted on both the telescopic block and the connecting blocks, a clamping block rotatably mounted on one end of the telescopic block, an extrusion block matching the telescopic block fixedly mounted on the support frame, a cleaning component mounted on the base, and a collecting component mounted on the base.

[0005] Preferably, the cleaning assembly includes two placement blocks fixedly installed on the base, the two placement blocks together fixedly installing a cleaning block, two support frames fixedly installing an arc rack, and two clamping blocks fixedly installing a spur gear, the spur gear meshing with the arc rack.

[0006] Preferably, the receiving component includes a platform fixedly mounted on a base, two mutually symmetrical slide rails fixedly mounted on the platform, the two slide rails being slidably connected to a receiving platform, a telescopic motor fixedly mounted on the platform, the output shaft of the telescopic motor fixedly mounted on the receiving platform, and a robotic arm fixedly mounted on the base.

[0007] Preferably, a protective sleeve is fitted onto the clamping block, and the protective sleeve is made of rubber.

[0008] Preferably, one end of the telescopic block is installed in a circular shape, and both ends of the compression block are installed in an arc shape.

[0009] Preferably, the limiting block is installed in an arc shape, and a friction layer is fitted on the limiting block.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. By stacking multiple bars into the limited placement box, the bars can be arranged in an orderly manner. At the same time, the bars can be separated into individual pieces by the clamping blocks, and finally removed by the robotic arm. The orderly placement and individual separation feeding method reduce the mutual friction and collision between the bars, thereby effectively ensuring the surface quality of the bars.

[0011] 2. Simultaneously, during the single-piece separation process, the rotation of the spur gear on the clamping block on the arc rack drives the bar to rotate while being transported, so that the surface of the bar is cleaned by the cleaning block, which can effectively remove the stains on the surface of the bar and ensure the quality of subsequent processing.

Detailed Implementation

[0016] Reference Figures 1-3 A bar stock feeding device, comprising: A base 1 is provided. A support frame 2 is fixedly installed on the base 1. A placement box 3 is fixedly installed on the support frame 2. A limit block 4 is fixedly installed on the placement box 3. Two support frames 5 are fixedly installed on the base 1. A rotary motor 6 is fixedly installed on one of the support frames 5. A rotating shaft 7 is fixedly installed on the output shaft of the rotary motor 6. Two connecting blocks 8 are fixedly installed on the rotating shaft 7. A telescopic block 9 is slidably connected to the connecting block 8. A spring 10 is fixedly installed on the telescopic block 9 together with the connecting block 8. A clamping block 11 is rotatably installed on one end of the telescopic block 9. A squeezing block 12 that matches the telescopic block 9 is fixedly installed on the support frame 5. A cleaning component is installed on the base 1. A collection component is installed on the base 1. First, the rods are placed in the placement box 3 for overall storage. Due to the height and width limitations of the placement box 3, the rods can be neatly arranged inside. Since the placement box 3 is installed at an angle, the rods at the bottom of the placement box 3 will move to the limiting block 4 due to gravity and the thrust of other rods, and stop on the limiting block 4. By starting the rotary motor 6, the rotating shaft 7 is rotated, causing the connecting block 8 fixedly connected to the rotating shaft 7 to rotate, thus driving the telescopic block 9 forward. As the rod rotates upward, the telescopic block 9 is squeezed by the extrusion block 12, causing the two telescopic blocks 9 to move closer to each other and drive the two clamping blocks 11 to move closer to each other. When the telescopic block 9 moves completely onto the extrusion block 12, the clamping block 11 completes the clamping work of the rod. As the rotation continues, until it reaches the other end of the support frame 5, the telescopic block 9 gradually moves away from the extrusion block 12. At this time, under the elastic force of the spring 10, the telescopic block 9 is reset, thereby causing the clamping block 11 to stop clamping the rod. At this time, the rod is sent out. The cleaning assembly includes two placement blocks fixedly mounted on the base 1, with a cleaning block 13 fixedly mounted on both placement blocks, an arc rack 14 fixedly mounted on each of the two support frames 5, and a spur gear 15 fixedly mounted on each of the two clamping blocks 11, with the spur gear 15 meshing with the arc rack 14. When the rotating shaft 7 rotates, the clamping block 11 has completed clamping the bar. Through the rotational connection between the clamping block 11 and the telescopic block 9, and when the clamping block 11 rotates to the designated position, the spur gear 15 contacts the arc rack 14, thereby driving the rotation of the spur gear 15, which in turn drives the clamping block 11 to rotate, thereby driving the bar to rotate. At this time, the bar rolls on the cleaning block 13, and the surface of the bar can be cleaned by the cleaning block 13. The receiving component includes a platform 16 fixedly mounted on a base 1. Two mutually symmetrical slide rails 17 are fixedly mounted on the platform 16. The two slide rails 17 are slidably connected to a receiving platform 18. A telescopic motor 19 is fixedly mounted on the platform 16. The telescopic motor 19 is existing technology and can enable objects connected to its output shaft to move linearly. The output shaft of the telescopic motor 19 is fixedly mounted on the receiving platform 18. A robotic arm 20 is fixedly mounted on the base 1. By starting the telescopic motor 19, the receiving platform 18 is moved on the slide rail 17. By adjusting the position of the receiving platform 18, after the receiving platform 18 receives the bar, the position of the receiving platform 18 can be moved so that it will not interfere with the movement of the connecting block 8. At the same time, the bar can be moved under the robotic arm 20, making it more convenient for the robotic arm 20 to pick it up. The clamping block 11 is fitted with a protective sleeve made of rubber. The protective sleeve can effectively protect the bar and reduce the clamping damage caused by the clamping block 11. One end of the telescopic block 9 is installed in a round shape, and both ends of the compression block 12 are installed in an arc shape. The round telescopic block 9 and the arc-shaped compression block 12 make it easier for the telescopic block 9 to be squeezed and pushed by the compression block 12. The limiting block 4 is installed in an arc shape and is fitted with a friction layer. By setting the friction layer, the stability of the bar when it stays on the limiting block 4 can be guaranteed, which facilitates the clamping operation.

[0017] The working principle of this invention is as follows: First, the rods are placed in the placement box 3 for overall storage. Due to the height and width limitations of the placement box 3, the rods can be neatly arranged within it. Since the placement box 3 is installed at an angle, the rods at the bottom of the placement box 3 will move to the limiting block 4 due to gravity and the thrust of other rods, and stop on the limiting block 4. By starting the rotary motor 6, the rotating shaft 7 rotates, causing the connecting block 8 fixedly connected to the rotating shaft 7 to rotate. This causes the telescopic block 9 to rotate and rise. During the rising process, the telescopic block 9 is squeezed by the pressing block 12, causing the two telescopic blocks 9 to move closer together, and also causing the two clamping blocks 11 to move closer together. When the telescopic block 9 is completely moved onto the pressing block 12, the clamping block 11 completes the clamping work on the rod. As rotation continues until it reaches the other end of the support frame 5, the telescopic block 9 gradually moves away from the pressing block 12. At this time, the spring... Under the elastic reset of 10, the telescopic block 9 is reset, thereby causing the clamping block 11 to stop clamping the bar. At this time, the bar is sent out. When the rotating shaft 7 rotates, the clamping block 11 has completed clamping the bar. Through the rotational connection between the clamping block 11 and the telescopic block 9, and when the clamping block 11 rotates to the designated position, the spur gear 15 contacts the arc rack 14, thereby driving the rotation of the spur gear 15. This can drive the clamping block 11 to rotate, thereby driving the bar to rotate. At this time, the bar rolls on the cleaning block 13. The cleaning block 13 can clean the surface of the bar. By starting the telescopic motor 19, the receiving platform 18 is driven to move on the slide rail 17. By adjusting the position of the receiving platform 18, after the receiving platform 18 receives the bar, the position of the receiving platform 18 can be moved so as not to interfere with the movement of the connecting block 8. At the same time, the bar can be moved under the robotic arm 20, making it more convenient for the robotic arm 20 to pick it up.
