DETAILED DESCRIPTION

[0047] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure can be variously implemented and should not be limited by the embodiments set forth herein. Rather, the embodiments are provided to enable those skilled in the art to more thoroughly understand and convey the scope of the present disclosure.

[0048] In the description of the present application, it should be pointed out that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "far", "near", "front", "back" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0049] In the description of the present application, it should be pointed out that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0050] The inventor found that in the prior art, in the machining process of some large-length-diameter ratio shaft workpieces, the main shaft of the workpiece machining equipment clamps one end of the workpiece, and the other end of the workpiece is suspended outside the workpiece machining equipment. When the main shaft rotates, the workpiece suspended outside the workpiece machining equipment will fly up due to centrifugal force, which is dangerous and affects the machining precision of the workpiece. In the prior art, a simple supporting device is used to support the workpiece, which is composed of two shock-absorbing wheels arranged below the workpiece. The shock-absorbing wheels can support the lower part of the workpiece, but cannot limit the upper part of the workpiece. When the main shaft rotates, the workpiece will still move upward, which poses a risk to the machining precision and safety.

[0051] In order to solve the above problems, the inventor has developed an automatic centering auxiliary supporting device and a workpiece machining equipment, which ensures the machining precision and safety during the machining process of the workpiece.

[0052] Embodiment one

[0053] Reference Figures 1-3This embodiment proposes an automatic centering auxiliary support device, which can be applied in workpiece processing equipment to provide auxiliary support for the workpiece. The support device includes: a first connecting rod 1, a second connecting rod 3, a first active clamping member 2, a second active clamping member 11, a first driven clamping member 4, a second driven clamping member 10, a driving member 15, a transmission assembly, a base 9, and a support shaft 5.

[0054] The first end of base 9 (i.e. Figure 1 The upper end of the base 9 shown) and the second end (i.e. Figure 1 The lower end of the base 9 shown in the diagram is provided with a support shaft 5 and a transmission assembly. The first active clamping member 2 and the first driven clamping member 4 are sleeved on the support shaft 5. The support shaft 5 supports the rotation of the first active clamping member 2 and the first driven clamping member 4, ensuring they can rotate stably downwards around the axis of the support shaft 5, thus limiting the upper part of the workpiece. Simultaneously, the first active clamping member 2 and the first end of the first connecting rod 1 (i.e.,...) Figure 1 The upper end of the first connecting rod 1 shown in the figure is rotatably connected, and the first driven clamping member 4 is rotatably connected to the second connecting rod 3. Specifically, the upper end of the first driven clamping member 4 is rotatably connected to the second connecting rod 3.

[0055] The transmission assembly includes an input shaft 16 and an output shaft 17. The second connecting rod 3 is rotatably connected to the output shaft 17. One end of the second active clamping member 11 is connected to the second end of the first connecting rod 1 (i.e.,...). Figure 1 The lower end of the first connecting rod 1 shown is rotatably connected, and the other end of the second active clamping member 11 is connected to the input shaft 16. The second driven clamping member 10 is sleeved on the input shaft 16 and rotatably connected to the output shaft 17. The transmission assembly is used to transmit the movement of the second active clamping member 11 to the second driven clamping member 10 and the second connecting rod 3, so as to realize the linkage of the entire support device.

[0056] The driving member 15 is the power source of the whole supporting device. The driving member 15 is connected with the first connecting rod 1 and can drive the first connecting rod 1 to move in the vertical direction, drive the first active clamping member 2 and the second active clamping member 11 to rotate, drive the second passive clamping member 10 to rotate through the input shaft 16 and the output shaft 17, and drive the second connecting rod 3 to drive the first passive clamping member 4 to rotate, so as to cause the linkage of the whole device. Specifically, in use, the workpiece (not shown in the figure) is in the clamping area (i.e. above the second active clamping member 11 and the second passive clamping member 10, and below the first active clamping member 2 and the first passive clamping member 4), the driving member 15 drives the first connecting rod 1 to move upward in the vertical direction, the first connecting rod 1 drives the first active clamping member 2 and the second active clamping member 11 to rotate towards each other, i.e. the first active clamping member 2 rotates downward around the axis of the supporting shaft 5, and the second active clamping member 11 rotates upward around the axis of the input shaft 16. At the same time, the movement of the second active clamping member 11 is transmitted to the output shaft 17 by the input shaft 16, on the one hand, the output shaft 17 drives the second connecting rod 3 to move, and the second connecting rod 3 drives the first passive clamping member 4 to rotate downward around the axis of the supporting shaft 5; on the other hand, the output shaft 17 drives the second passive clamping member 10 to rotate upward around the axis of the output shaft 17. The first active clamping member 2 and the first passive clamping member 4 both rotate downward around the axis of the supporting shaft 5 to limit the upper part of the workpiece; the second active clamping member 11 and the second passive clamping member 10 rotate upward around the axis of the input shaft 16 to limit the lower part of the workpiece.

[0057] In the embodiment, the first active clamping member 2, the first passive clamping member 4, the second active clamping member 11 and the second passive clamping member 10 cooperate to limit the workpiece in all directions. When the main shaft of the workpiece processing equipment rotates, the workpiece is effectively limited and will not move as in the prior art, thereby effectively ensuring the processing accuracy and safety of the workpiece. The whole supporting device can automatically realize accurate clamping of the workpiece without manual intervention, thereby improving the processing efficiency and accuracy. At the same time, the whole supporting device has a relatively small and compact structure and occupies a small space. In the embodiment, only one driving member 15 is needed to realize the movement of the first active clamping member 2, the first passive clamping member 4, the second active clamping member 11 and the second passive clamping member 10, clamp and position the workpiece, and realize automatic centering, automatic clamping or loosening of the workpiece.

[0058] In a specific embodiment, reference is made to Figure 1 and Figure 4The transmission assembly further comprises a transmission member 7 and a rotary connecting member 14. The transmission member 7 is arranged at the second end of the base 9 and is connected with the input shaft 16 and the output shaft 17 respectively. When the second driving clamp 11 moves, the power generated thereby is transmitted to the input shaft 16, and the transmission member 7 transmits the power on the input shaft 16 to the output shaft 17. Here, the transmission member 7 can adopt the components in the prior art such as gears, pulleys, chains and the like, as long as the components can realize transmission. The two ends of the rotary connecting member 14 are rotatably connected with the output shaft 17 and the second connecting rod 3 respectively, for transmitting the power on the output shaft 17 to the second connecting rod 3, thereby providing the first driven clamp 4 with the power for rotation. By arranging the transmission member 7 and the rotary connecting member 14, the power transmission from the input shaft 16 to the output shaft 17 is more direct and efficient, and the energy loss and transmission error are reduced, thereby ensuring that the second connecting rod 3 can more stably follow the rotation of the output shaft 17, and further drive the first driven clamp 4 to accurately clamp the workpiece, which helps to reduce the movement of the workpiece in the machining process and improve the machining precision.

[0059] In one specific embodiment, referring to Figure 1 The transmission assembly further comprises a connecting plate 13, the two ends of the connecting plate 13 being rotatably connected with the rotary connecting member 14 and the second driven clamp 10 respectively.

By arranging the connecting plate 13, the power of the output shaft 17 can be transmitted to the second driven clamp 10, and the second driven clamp 10 can rotate to accurately clamp the workpiece, which helps to reduce the movement of the workpiece in the machining process and improve the machining precision and product quality.

[0060] In one specific embodiment, referring to Figure 1 The transmission member 7 comprises a driving gear (not shown in the figure) and a driven gear (not shown in the figure), the driving gear and the driven gear being engaged with each other to realize the transmission of power. The driving gear is connected with the input shaft 16 to receive the power from the second driving clamp 11, and the driven gear is connected with the output shaft 17 to transmit the power to the output shaft 17. By arranging the driving gear and the driven gear, the gear transmission mode is realized, which has high accuracy and stability, can ensure that the transmission ratio between the input shaft 16 and the output shaft 17 remains constant, and helps to reduce the transmission error, thereby stably realizing the rotation of the first driven clamp 4 and the second driven clamp 10 to accurately clamp the workpiece, which helps to reduce the movement of the workpiece in the machining process and improve the machining precision and product quality.

[0061] In one specific embodiment, referring to Figures 1-3The support device further comprises a limiting scale 6 arranged at the first end of the base 9, and the limiting scale 6 is arranged above the support shaft 5.

The limiting scale 6 serves as a reference point or a limiting position for the stop rod 18, and when the first driven clamping piece 4 rotates to a predetermined position, the stop rod 18 will contact the limiting scale 6, thereby limiting the further movement thereof. Through the cooperation of the limiting scale 6 and the stop rod 18, the movement range and position of the first driven clamping piece 4 can be accurately controlled, the clamping stroke is controlled, the clamping error is reduced, and the machining precision and product quality are improved. Meanwhile, the limiting scale 6 can move in the horizontal direction, the clamping stroke is changed, and the support device is more adaptable to workpieces of different shapes and sizes.
