Description

Technical Field

[0001] The utility model relates to the technical field of machining, and specifically relates to a transfer rack for round bar workpieces. Background Art

[0002] At present, round bar workpieces are usually placed on a rack, and a handling robot moves a clamping device to clamp the round bar workpieces placed on the rack. Since the round bar workpieces placed on the rack are closely attached to each other, it is inconvenient for the clamping device to clamp a single round bar workpiece, thus making it inconvenient to transfer the round bar workpieces placed on the rack; if the rack is designed into multiple independent grids or slots, each grid or slot only accommodates one round bar workpiece. Although this can avoid the close attachment between round bar workpieces, the handling robot needs to move the clamping device to different positions to clamp the round bar workpieces, which increases the complexity of the control system of the handling robot. Therefore, we propose a transfer rack for round bar workpieces. Content of the Utility Model

[0003] The purpose of the utility model is to improve and innovate in view of the defects and problems in the background art, and provide a transfer rack for round bar workpieces.

[0004] A transfer rack for round bar workpieces includes a bracket. A plurality of support square tubes are arranged side by side at the top of the bracket. A plurality of round bar workpieces are placed on the support square tubes. The support square tubes are inclined so that the round bar workpieces can roll downward along the length direction of the support square tubes. A turnover mechanism is arranged at the end of the support square tubes and a base plate is installed. A plurality of blanking plates are installed at intervals on the base plate. The end of the blanking plate away from the base plate protrudes upward to form a hook portion. The turnover mechanism is used to transfer each round bar workpiece to the blanking plate in sequence. The blanking plate is inclined so that the transferred round bar workpieces roll downward to the hook portion.

[0005] Further, the turnover mechanism includes a hydraulic cylinder. The hydraulic cylinder is rotatably connected to the bracket. The telescopic end of the hydraulic cylinder is fixedly connected with an oil cylinder push block. First bearing seats are installed on the base plates on both sides of the bracket. A first linkage shaft is rotatably connected between the two first bearing seats. A plurality of turnover plates are installed at intervals on the first linkage shaft. The end of the turnover plate away from the support square tube is installed on a second linkage shaft. The oil cylinder push block is sleeved on the second linkage shaft. The turnover plates are grouped in pairs, and a baffle block is installed between a group of turnover plates. The surface of the baffle block close to the support square tube is inclined, and the end close to the support square tube is lower than the end away from the support square tube.

[0006] Further, the middle of the first linkage shaft is rotatably connected to a second bearing seat, and the second bearing seat is installed on the base plate.

[0007] A further solution is that both the first linkage shaft and the second linkage shaft are fixedly connected to the turnover plate through expansion sleeves.

[0008] A further solution is that the substrate is installed at the end of the support square pipe.

[0009] A further solution is that the oil cylinder push block is sleeved on the second linkage shaft through a graphite copper sleeve.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: by placing round bar-shaped workpieces on the inclined support square pipe, each round bar-shaped workpiece can automatically roll down along the support square pipe under the action of gravity to the turnover mechanism; through the mutual cooperation of the hydraulic cylinder, the oil cylinder push block, the material retaining block, the first linkage shaft, the second linkage shaft and the turnover plate of the turnover mechanism, the hydraulic cylinder drives the turnover plate and the material retaining block to rotate around the first linkage shaft; the turnover plate jacks up a single round bar-shaped workpiece and drives the workpiece to slide to the joint of the material retaining block and the turnover plate; and under the guiding action of the material retaining block, it smoothly slides onto the blanking plate, realizing the transfer of each round bar-shaped workpiece to the blanking plate in sequence, thus facilitating the subsequent transfer of the round bar-shaped workpieces.

The terms used in the description of the present utility model herein are only for the purpose of describing specific implementation manners and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0019] Please refer to Figures 1 - 3 , the present utility model provides a transfer rack for round bar workpieces, including a bracket 1. A plurality of support square tubes 101 are arranged side by side at the top of the bracket 1. A plurality of round bar workpieces 11 are placed on the support square tubes 101. The support square tubes 101 are inclined so that the round bar workpieces 11 can roll downward along the length direction of the support square tubes 101 under the action of gravity. A turning mechanism is provided at the end of the support square tubes 101 and a substrate 10 is installed. The substrate 10 is installed at the end of the support square tubes 101. A plurality of blanking plates 9 are installed at intervals on the substrate 10. One end of the blanking plate 9 away from the substrate 10 protrudes upward to form a hook portion 91. The turning mechanism is used to transfer each round bar workpiece 11 to the blanking plate 9 in sequence. The blanking plate 9 is inclined so that the transferred round bar workpieces 11 roll downward to the hook portion 91, facilitating the subsequent transfer of the round bar workpieces 11. The hook portion 91 prevents the round bar workpieces 11 from sliding out of the blanking plate 9.

[0020] Specifically, the material turning mechanism includes a hydraulic cylinder 2, which is rotatably connected to the bracket 1, and a cylinder push block 3 is fixedly connected to the telescopic end of the hydraulic cylinder 2. First bearing seats 12 are installed on the base plates 10 on both sides of the bracket 1, and a first linkage shaft 7 is rotatably connected between the two first bearing seats 12. Turning plates 6 are installed at intervals on the first linkage shaft 7. One end of the turning plate 6 away from the support square tube 101 is installed on a second linkage shaft 4, and one end of the turning plate 6 close to the support square tube 101 is arc-shaped. In this embodiment, both the first linkage shaft 7 and the second linkage shaft 4 are fixedly connected to the turning plate 6 through expansion sleeves 5.

The turning plates 6 are grouped in pairs, and a material blocking block 8 is installed between a group of turning plates 6. The material blocking block 8 is installed on the upper surface of the turning plate 6 through bolts. One side of the material blocking block 8 close to the support square tube 101 is inclined, and the end close to the support square tube 101 is lower than the end away from the support square tube 101. When the hydraulic cylinder 2 expands and contracts, through the mutual cooperation of the cylinder push block 3, the first linkage shaft 7 and the second linkage shaft 4, the turning plate 6 and the material blocking block 8 will be driven to rotate around the first linkage shaft 7; the turning plate 6 lifts the round bar workpiece 11 closest to the base plate 10 and drives the round bar workpiece 11 to slide to the joint of the material blocking block 8 and the turning plate 6; at this time, the arc end of the turning plate 6 abuts against other round bar workpieces 11, preventing other round bar workpieces 11 from rolling down; and the round bar workpiece 11 that slides to the joint of the material blocking block 8 and the turning plate 6 slides smoothly onto the blanking plate 9 under the guiding action of the material blocking block 8, realizing the transfer of each round bar workpiece 11 to the blanking plate 9 in sequence, thus facilitating the subsequent transfer of the round bar workpieces 11.

[0021] Preferably, the middle of the first linkage shaft 7 is rotatably connected to a second bearing seat 13, and the second bearing seat 13 is installed on the base plate 10.
