[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. It mainly consists of a casing, motor, main shaft, and impeller. The fan main shaft is a crucial component connecting the impeller and the motor, and it transmits torque. It is made of stainless steel. During the manufacturing process, the cylindricity and end faces of the fan main shaft need to be machined.

[0003] When machining the end face of a fan spindle, after machining one side, the spindle needs to be rotated and then transported to the next station to machine the other end face. Traditionally, this rotation is achieved using a robotic arm, which is costly and inefficient. Summary of the Invention

The first linkage mechanism includes a rotating rod that is rotatably connected to the column at the middle position and a first connecting rod disposed at both ends of the rotating rod. The outer end of the first connecting rod is rotatably connected to the corresponding lifting beam, and the inner end of the first connecting rod is rotatably connected to the end of the corresponding rotating rod. The second linkage mechanism includes a first connecting rod, a second connecting rod, a first belt, a second belt, and a drive shaft mounted on and rotating on the support rod.

The end of the first connecting rod away from the second connecting rod is rotatably connected to the rotating shaft, and the end of the second connecting rod away from the first connecting rod is rotatably connected to the drive shaft. The rotating shaft is connected to the drive shaft through the first belt and the second belt. A rack is provided at the lower end of the turntable, and a gear that meshes with the rack is provided on the drive shaft.

[0006] Furthermore, both the fixed frame and the movable frame are provided with a plurality of positioning grooves at their upper ends for positioning the fan main shaft.

[0007] Furthermore, both the rear end of the upper lifting beam and the rear end of the lower lifting beam are provided with guide sleeves that cooperate with the column.

[0008] Furthermore, the pressure rod passes through the upper lifting beam and is slidably connected to the upper lifting beam. The lower end of the pressure rod is provided with a pressure head that is rotatably connected to the pressure rod. The pressure rod is provided with a compression spring. The lower end of the compression spring contacts the pressure head, and the upper end of the compression spring contacts the upper lifting beam. The pressure rod is provided with a baffle above the upper lifting beam.

[0009] Furthermore, the column is equipped with a drive mechanism for driving the upper lifting beam to rise and fall.

[0010] Furthermore, the drive mechanism includes a motor, a turntable mounted on the motor output shaft, and a second connecting rod. The upper end of the second connecting rod is rotatably connected to the turntable at an eccentric position, and the lower end of the second connecting rod is rotatably connected to the upper lifting beam.

[0011] Furthermore, the motor output shaft is connected to the rotating shaft via a belt.

[0012] Furthermore, a support plate is provided between the two columns, and the middle position of the rotating rod is rotatably connected to the support plate.

[0013] The beneficial effects of this invention are: 1. The present invention includes a fixed frame for supporting the main shaft of a fan, a movable frame for sequentially conveying the main shaft of the fan on the fixed frame to the left, and a steering mechanism for turning the main shaft of the fan; the movable frame conveys the main shaft of the fan on the fixed frame to the left in sequence, and at the same time, under the action of the steering mechanism, the main shaft of the fan achieves a 180-degree turn.

At this time, the fan main shaft is located in the slot, the pressure rod falls and presses down on the fan main shaft, and as the rotating shaft rotates, the turntable rotates 180 degrees under the action of the second linkage mechanism, thereby realizing the steering of the fan main shaft. As the fan main shaft is conveyed to the left in sequence, the mechanical linkage of the fan main shaft steering results in a compact cycle, high efficiency, simple structure, and low cost.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0019] like Figure 1 As shown, a steering device for processing and conveying a fan spindle includes a fixed frame 1 for supporting the fan spindle, a movable frame 2 for sequentially conveying the fan spindle on the fixed frame 1 to the left, and a steering mechanism for steering the fan spindle. The fixed frame 1 is fixed to the ground, and the two side plates of the movable frame 2 are connected as a whole by a bottom crossbeam. The movable frame conveys the fan spindle on the fixed frame 1 to the left in sequence, and at the same time, under the action of the steering mechanism, the fan spindle achieves a 180-degree turn. Compared with the steering of a robotic arm, it has a compact cycle, high efficiency, simple structure, and low cost.

[0020] like Figure 1 As shown, the fixed frame 1 is provided with support frames 3 on both sides, and the two support frames 3 are provided with rotating shafts 4 on both side walls. The rotating shafts on the same side are connected by belts (not shown in the figure, this is prior art and will not be described in detail here). One end of the inner side of the rotating shaft 4 is provided with a swing arm 5, that is, there are four swing arms 5, and the four swing arms 5 are parallel to each other. The end of the swing arm 5 is rotatably connected to the side of the movable frame 2. When the swing arm 5 rotates, it drives the movable frame 2 to swing. When the movable frame 2 swings from bottom to top, it lifts the fan main shaft on the fixed frame 1. Then the movable frame 2 swings to the left and down, and the fan main shaft moves to the left by one distance. The movable frame 2 repeats the action, realizing the fan main shaft moving to the left at intervals.

[0021] like Figure 2 and Figure 3As shown, the steering mechanism includes a column 7, an upper lifting beam 8 located at the upper end of the column 7, and a lower lifting beam 9 located at the lower end of the column 7. Two columns 7 are arranged side-by-side. The upper lifting beam 8 has a pressure rod 10 for pressing down on the fan main shaft. The lower lifting beam 9 has a support rod 11. A turntable 12 is located at the upper end of the support rod 11. The turntable 12 and the support rod 11 are rotatably connected by bearings; this is existing technology and will not be elaborated further. The turntable 12 has a slot 13 that mates with the fan main shaft. When the upper lifting beam 8 rises and falls, it is in the first linkage... Under the action of the mechanism, the lower lifting beam 9 rises and falls, and when the rotating shaft 4 rotates, the turntable 12 rotates under the action of the second linkage mechanism. When the upper lifting beam 8 falls, the lower lifting beam 9 rises synchronously under the action of the first linkage mechanism, and the turntable 12 lifts the fan main shaft. At this time, the fan main shaft is located in the slot 13, and the pressure rod 10 falls to press down on the fan main shaft. As the rotating shaft rotates, the turntable 12 rotates 180 degrees under the action of the second linkage mechanism, thereby realizing the rotation of the fan main shaft. As the fan main shaft is conveyed to the left in sequence, the mechanical linkage fan main shaft rotates. The cycle is compact, the efficiency is high, and the structure is simple and the cost is low.

[0022] like Figure 4 As shown, the first linkage mechanism includes a rotating rod 14 rotatably connected to the column 7 at the middle position and a first connecting rod 15 disposed at both ends of the rotating rod 14. The outer end of the first connecting rod 15 is rotatably connected to the corresponding lifting beam, and the inner end of the first connecting rod 15 is rotatably connected to the end of the corresponding rotating rod 14. When the upper lifting beam 8 is raised and lowered, the lower lifting beam 9 is raised and lowered synchronously under the action of the first connecting rod 15 and the rotating rod 14.

[0023] like Figure 3 and Figure 4 As shown, the second linkage mechanism includes a first connecting rod 16, a second connecting rod 17, a first belt 18, a second belt 19, and a drive shaft 20 mounted on and rotating on the support rod 11. The first connecting rod 16 is hinged to the second connecting rod 17, and a rotatable pin is provided at the hinge point. The end of the first connecting rod 16 away from the second connecting rod 17 is rotatably connected to the rotating shaft 4, and the end of the second connecting rod 17 away from the first connecting rod 16 is rotatably connected to the drive shaft 20. The rotating shaft 4 is connected to the drive shaft 20 through the first belt 18 and the second belt 19. A rack 21 is provided at the lower end of the turntable 12, and a gear 22 that meshes with the rack 21 is provided on the drive shaft 20.

[0024] Because the lower lifting beam 9 is raised and lowered, and the position of the rotating shaft is inconvenient, the rotation of the turntable 12 requires it to be connected to the rotating shaft. The rotation of the rotating shaft drives the turntable 12 to rotate so as to realize the rotation of the fan main shaft. This can be achieved through the second linkage mechanism.

[0025] In use, when the rotating shaft 4 rotates, it drives the first belt 18 to move, and the first belt 18 drives the second belt 19 to move, which in turn causes the drive shaft to rotate. In this process, two coaxial pulleys are fixed on the pivot pin that is hinged to the first connecting rod 16 and the second connecting rod 17. One pulley is connected to the rotating shaft 4 through the first belt 18, and the other pulley is connected to the drive shaft through the second belt 19.

[0026] like Figure 1 As shown, both the fixed frame 1 and the movable frame 2 are provided with a number of positioning slots 6 for positioning the fan main shafts. The number of positioning slots 6 on both is the same, and the spacing between adjacent positioning slots 6 is the same. Each time the movable frame 2 swings, it moves a number of fan main shafts on the fixed frame 1 one grid to the left.

[0027] like Figure 2 As shown, both the rear end of the upper lifting beam 8 and the rear end of the lower lifting beam 9 are provided with guide sleeves 23 that cooperate with the column 7.

[0028] like Figure 1 As shown, the pressure rod 10 passes through the upper lifting beam 8 and is slidably connected to it. A pressure head 24 is rotatably connected to the lower end of the pressure rod 10. The pressure head 24 is rotatably connected to the support rod 11 via a bearing; this is existing technology and will not be elaborated further. A compression spring 25 is provided on the pressure rod 10. The lower end of the compression spring 25 contacts the pressure head 24, and the upper end of the compression spring 25 contacts the upper lifting beam 8. A baffle is provided above the upper lifting beam 8 to prevent the pressure rod 10 from falling. When the upper lifting beam 8 descends and the pressure head 24 presses down on the fan main shaft, the pressure rod 10 moves upward against the spring force of the compression spring, providing a buffering effect to prevent equipment damage. It also ensures that the fan main shaft is pressed down, reducing the equipment's machining accuracy requirements.

[0029] like Figure 2 As shown, the column 7 is equipped with a drive mechanism for raising and lowering the upper lifting beam 8. The drive mechanism includes a motor 26, a turntable 27 mounted on the output shaft of the motor 26, and a second connecting rod 28. The upper end of the second connecting rod 28 is rotatably connected to the turntable 27 at an eccentric position, and the lower end of the second connecting rod 28 is rotatably connected to the upper lifting beam 8. When the turntable 27 rotates, the upper lifting beam 8 continuously rises and falls under the action of the second connecting rod 28.

[0030] like Figure 2 As shown, the output shaft of the motor 26 is connected to the rotating shaft 4 via a belt 29.

[0031] like Figure 4 As shown, a support plate 30 is provided between the two columns 7, and the rotating rod 14 is rotatably connected to the support plate 30 at its middle position.

[0032] In the description of the present invention, it should be noted that the terms "left", "right", "up", "down", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
