[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] The present application discloses a ring-type workpiece transfer device, referring to Figure 1 and Figure 2 , including a transport trolley 1, which has a built-in driving mechanism so that the transport trolley 1 can move on the ground. A mounting frame 2 is vertically provided on one side of the transport trolley 1, and a lifting frame 3 is vertically slidably provided on the mounting frame 2. A support rod assembly 4 for inserting into and hanging the ring-like workpiece is horizontally provided on the side of the lifting frame 3 away from the transport trolley 1. A support seat 5 for supporting the bottom of the ring-like workpiece is provided on the side of the mounting frame 2 away from the transport trolley 1. The support seat 5 is located below the support rod 41. A placement groove 51 for adapting to the placement of the ring-like workpiece is opened on the support seat 5 along the length direction of the support rod 41. A first driving assembly for driving the lifting frame 3 to move vertically is provided on the mounting frame 2. When placing the ring-like workpiece, the lifting frame 3 is lowered, the ring-like workpiece is put on the support rod assembly 4, and the bottom of the ring-like workpiece is dragged by the support seat 5. When the workpiece is transported, the lifting frame 3 is raised so that the ring-like workpiece is suspended on the support rod assembly 4, thereby preventing the workpiece from tipping over during transportation.

[0019] In this embodiment of the present application, the first drive assembly includes a gear 21, a chain 22, and a drive hydraulic cylinder 23. The drive hydraulic cylinder 23 is vertically fixedly mounted on the transport trolley 1, with the piston rod of the drive hydraulic cylinder 23 pointing vertically upward. The gear 21 is rotatably mounted on the top of the drive hydraulic cylinder 23. The chain 22 is wound around the gear 21, with one end of the chain 22 fixedly connected to the mounting frame 2 and the other end fixedly connected to the lifting frame 3. The movement of the piston rod of the drive hydraulic cylinder 23 causes the gear 21 to rise and fall, and the lifting frame 3 to rise and fall vertically relative to the mounting frame 2.

[0020] In the embodiment of the present application, the support rod assembly 4 includes two parallel support rods 41, a mounting base 31 is provided on the lifting frame 3, a slide groove is horizontally provided on the mounting base 31, two sliders 32 are slidably installed in the slide groove, and a second driving member is provided on the mounting base 31 for driving the two sliders 32 to move synchronously closer / away. Specifically, the second driving member includes a driving motor 34, a bidirectional screw rod 33 is horizontally provided on the mounting base 31, and the driving motor 34 is used to drive the bidirectional screw rod 33 to rotate. The two sliders 32 are respectively threadedly connected to the opposite threaded sections at both ends of the bidirectional screw rod 33, and the two support rods 41 are respectively fixed on the two sliders 32. After the annular workpiece is sleeved on the two support rods 41, the load is shared by the two support rods 41, which can improve the bearing capacity of the support rod assembly 4, and the two support rods 41 are notified to support the inner side of the annular workpiece, which can prevent the workpiece from shaking left and right during the transportation process, thereby improving the stability of the workpiece during transportation.

[0021] Furthermore, a first abutment piece 35 is fixedly provided on the outer wall of the support rod 41 near the slider 32, and a limiter is provided on the end of the support rod 41 away from the slider 32 for limiting the sliding movement of the annular workpiece on the support rod 41. Specifically, the limiter includes a movable rod 6, which is slidably provided on the bottom wall of the support rod 41 along the length direction of the support rod 41. The support rod 41 is provided with an electric push rod 61, which is used to drive the movable rod 6 to move. The end of the movable rod 6 away from the slider 32 extends out of the support rod 41 and is fixed with a second abutment piece 62. The second abutment piece 62 is used to abut the end face of the annular workpiece on the support rod 41 away from the slider 32. The side of the second abutment piece 62 near the mounting seat 31 can also be integrally fixed with an abutment portion extending along the axis of the support rod 41. After the workpiece is suspended on the support rod assembly 4, the first abutment piece 35 can be used to limit the workpiece near the transport trolley 1, preventing the workpiece from contacting the mounting seat 31, the lifting frame 3, and other structures, which would cause wear on the end face of the workpiece. Furthermore, by retracting the movable rod 6 of the electric push rod 61 , the second abutment piece 62 and the abutment portion can abut against the end of the workpiece away from the transport trolley 1 , preventing the workpiece from sliding off the support rod 41 and improving the stability of the workpiece during transportation.

[0022] Furthermore, the support base 5 is provided with a plurality of placement slots 51 arranged in parallel. The mounting base 31 is slidably mounted horizontally on the lifting frame 3. The lifting frame 3 is provided with a plurality of first positioning holes 36 spaced apart along the sliding direction of the mounting base 31. The mounting base 31 is provided with a second positioning hole. The mounting base 31 is secured to the lifting frame 3 via positioning bolts 37 and positioning nuts. The positioning bolts 37 pass through both the first positioning holes 36 and the second positioning holes and then threadably engage the positioning nuts. Depending on the size of the annular workpiece, the operator can select an appropriate number of mounting bases 31 for placement on the lifting frame 3 and position the assembly in the appropriate position using the positioning bolts 37 so that the mounting bases 31 correspond to the placement slots 51 on the support base 5. This allows for the simultaneous transport of multiple groups of annular workpieces, improving transfer efficiency.

[0023] Furthermore, an anti-slip layer is provided on the inner bottom wall of the placement groove 51. The anti-slip layer may be a rubber layer to increase the friction between the workpiece and the inner wall of the placement groove 51, thereby improving the stability of the workpiece in the placement groove 51. A Teflon sleeve is coaxially provided on the outer wall of the support rod 41. The Teflon sleeve reduces the friction between the support rod 41 and the inner wall of the workpiece, thereby preventing wear on the inner wall of the workpiece during suspension transportation.
