[0041] The rotating block 5 has a front end threadedly connected with a supporting ball rod 51 .

[0042] In this embodiment, Figure 1 and Figure 3 As shown, an arm fixing plate 6 is fixedly provided on the top of the fixing plate 1, a first compound-acting cylinder 7 is fixedly provided on the front bottom of the arm fixing plate 6, and a V-shaped pressing plate 71 is fixedly provided on the bottom output end of the first compound-acting cylinder 7.

[0043] The arm fixing plate 1 is assembled with the mechanical arm configured by the customer, and the first double-acting cylinder 7 and the V-shaped pressing plate 71 cooperate to contact the outer side of the ring-shaped material.

[0044] In this embodiment, Figure 1 As shown, a connecting plate 8 is fixedly provided on the rear side of the V-shaped pressure plate 71 , and the rear side of the connecting plate 8 is fixedly connected to the moving end of the linear guide rail 81 , and the guide rail end of the linear guide rail 81 is fixedly connected to the front side of the fixed plate 1 .

[0045] The design and coordination of the connecting plate 8 and the linear guide rail 81 improves the movement stability of the V-shaped pressing plate 71 driven by the first compound cylinder 7 .

[0046] In this embodiment, Figure 2 and Figure 4 As shown, the opposite sides of the two connecting shafts 2 are respectively engaged with the left and right sides of the rotating block 5 , and a bearing is provided at the connection between the outer side of the connecting shaft 2 and the fixed plate 1 .

[0047] The connecting shaft 2 and the rotating block 5 cooperate with each other, and the flat gear 3 is driven to rotate through the cylindrical rack 4 in the second compound cylinder 41. The flat gear 3 and the connecting shaft 2 cooperate to complete the deflection design of the rotating block 5 at the bottom of the fixed plate 1, and the support ball rod 51 cooperates with the rotating block 5 for deflection.

[0048] In this embodiment, Figure 2 and Figure 4 As shown, the cylindrical rack 4 is symmetrically arranged about the middle of the fixed plate 1, the top of the cylindrical rack 4 is fixedly connected to the bottom output end of the second double-acting cylinder 41, and the outer sides of the two second double-acting cylinders 41 are fixedly connected to the left and right sides of the bottom of the fixed plate 1 respectively.

[0049] The second double-acting cylinder 41 drives the cylindrical rack 4 to move upward and downward inside the fixed plate 1 , thereby completing the rotation design of the spur gear 3 inside the fixed plate 1 .

[0050] In this embodiment, Figure 2 , Figure 3 and Figure 4 As shown, a guide groove is fixedly provided at the rear side of the bottom of the fixing plate 1 , and a limiting groove is fixedly provided at the bottom of the fixing plate 1 .

[0051] A third compound cylinder 9 is fixedly provided on the rear side of the fixed plate 1, and a safety gate plate 91 is fixedly provided on the bottom output end of the third compound cylinder 9. The front side of the safety gate plate 91 abuts against the rear side of the rotating block 5, and the safety gate plate 91 cooperates with the guide groove. A limiting protrusion is fixedly provided on the rear side of the safety gate plate 91, and the limiting protrusion cooperates with the limiting groove.

[0052] The structural design of the third double-acting cylinder 9 and the safety gate plate 91 provides a limit locking function for the working position of the rotating block 5 on the fixed plate 1 .

[0053] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, a rotating shaft is fixedly arranged in the middle of the rotating block 5 , and two ends of the rotating shaft are fixedly connected to the middle of the two flat gears 3 respectively.

[0054] According to the user's customization needs, a design scheme in which one integral rotating shaft replaces the two connecting shafts 2 can be adopted.

[0055] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rod body portion supporting the ball rod 51 is composed of a telescopic cylinder.

[0056] According to the customization needs of the user, the structural length of the supporting ball rod 51 can be further adjusted by using a telescopic cylinder to achieve the design goal of variable length of the supporting ball rod 51.

[0057] Specific operation process:

[0058] In an environment with sufficient working space, the support ball rod 51 can remain horizontal, and through the combination of the arm fixing plate 6 and the mechanical arm, it extends from the inner hole of the ring-shaped material to one side. The first compound cylinder 7 changes the working position of the V-shaped pressure plate 71, and cooperates with the support ball rod 51 to complete the material removal operation of the ring-shaped material.

[0059] In an environment with a narrow working space, the third compound cylinder 9 drives the safety gate 91 to move upward, releasing the limit lock of the safety gate 91 on the rotating block 5, and the second compound cylinder 41, the cylindrical rack 4, the flat gear 3 and the rotating shaft cooperate to adjust the orientation of the rotating block 5 and the supporting ball rod 51 to a vertical or non-horizontal direction. After the equipment moves close to the ring-shaped material, the rotating block 5 and the supporting ball rod 51 are adjusted to a horizontal direction. At this time, the supporting ball rod 51 extends into the inner hole of the ring-shaped material and cooperates with the V-shaped pressure plate 71 to complete the material picking operation.

[0060] The device can cooperate with the robot arm to complete the picking and placing operations of the ring-shaped material, so that the machine tool spindle can smoothly clamp and release the parts without being affected by the width of the ring-shaped material. When the space at the front end of the spindle is narrow, the support ball rod 51 can be withdrawn from the inner hole of the ring-shaped material without moving backwards, thereby completing the picking and placing operations of the ring-shaped material.

[0061] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
