In this embodiment, a first pad 21 is arranged on the translating beam 1, and the shaft workpiece 3 is placed on the first pad 21 to support the middle part of the shaft workpiece 3. The first pad 21 made of PP material contacts the bottom of the shaft workpiece 3 to avoid impact damage to the shaft workpiece 3.

[0019] A rotating shaft 16 extending along the width direction of the translation beam 1 is horizontally arranged in the bracket 2, and lifting arms 5 extending to both sides of the translation beam 1 are arranged at intervals on the rotating shaft 16. A roller 24 extending vertically to the corresponding side of the translation beam 1 is arranged on the lifting arm 5. A baffle bar 23 located above the roller 24 is arranged on the side of the translation beam 1. The lifting arm 5 is driven to rotate by the rotating shaft 16, and the translation beam 1 and the shaft workpiece 3 are lifted by the cooperation between the roller 24 and the baffle bar 23.

[0020] A fifth sprocket 25 is provided at one end of the rotating shaft 16, a second motor 7 is provided in the bracket 2, a sixth sprocket 27 corresponding to the fifth sprocket 25 is provided at the end of the second motor 7, and a third chain 26 is provided between the fifth sprocket 25 and the sixth sprocket 27. The rotation of the second motor 7 can be controlled by PLC to drive the rotation of the rotating shaft 16 to realize the rotation and swing of the lifting arm 5 at a certain angle. The rotation angle of the rotating shaft 16 is detected by a sensor, and the sensor sends a signal to the second motor 7 to ensure the rotation and swing control accuracy of the lifting arm 5.

[0021] A sleeve 15 corresponding to one of the rollers 24 is rotatably arranged on the rotating shaft 16, and the sleeve 15 has a bearing built therein, and does not rotate with the rotating shaft 16. A first sprocket 30 and a second sprocket 22 are arranged at intervals on the sleeve 15, and a third sprocket 19 corresponding to the first sprocket 30 is arranged on the roller 24, and a first chain is arranged between the first sprocket 30 and the third sprocket 19, so that the sleeve 15 can drive the roller 24 to rotate.

[0022] like Figure 1 As shown, the bracket 2 is provided with a first motor 6, and a fourth sprocket 28 corresponding to the second sprocket 22 is provided at the end of the first motor 6. Figure 4 As shown, a second chain 29 is provided between the second sprocket 22 and the fourth sprocket 28 , and the rotation of the first motor 6 is controlled by PLC to drive the rotation of the second sprocket 22 , thereby realizing the rotation of the sleeve 15 and the drum 24 .

[0023] The drum 24 where the third sprocket 19 is located is provided with a first gear 31, and the first rack 20 meshing with the first gear 31 is provided on the outer side of the translation beam 1 or the baffle, and the translation beam 1 is driven to move forward and backward by the rotation of the drum where the third sprocket 19 is located. Figure 4 As shown, the roller 24 where the first gear is located is provided with a rolling bearing 32 that is in rolling contact with the stop bar, that is, the roller 24 where the first gear 31 is located has bearings inside and outside, which can support the translation beam 1 and drive the translation beam 1 to move forward and backward. The other roller only has a built-in bearing for passive rotation to provide rolling support for the translation beam 1.

[0024] like Figure 1 As shown, the lifting of the translational beam 1 is achieved through the action of the lifting arms 5 in the multiple brackets 2, which greatly improves the load capacity and stability during the lifting process and improves the adaptability to the shaft workpiece 3 with large dead weight.

[0025] After the shaft workpiece 3 is transferred to the top of the subsequent workstation, the last rotating shaft 16 drives the lifting arm 5 to rotate and reset, and the shaft workpiece 3 falls into the workstation for cleaning of the corresponding process, which is beneficial to the isolation between processes. In this embodiment, a support beam 17 is provided on the bracket 2 and is located on both sides of the translation beam 1. A second pad 18 is provided on the support beam 17. When the shaft workpiece 3 falls, it can contact the second pad 18, which improves the balance effect of the shaft workpiece 3 and helps to reduce the flipping problem of the shaft workpiece 3.

The V-shaped fixtures 14 are used to self-center and support the two ends of the shaft workpiece to avoid the problem of tilting at both ends. When cleaning the shaft workpiece 3, both ends can fall onto the V-shaped fixtures 14, which has high stability.

[0027] A guide rod 13 is provided on the anti-roll frame 10, which is located below the slide 4 and extends along the width direction of the translation beam 1, to support the longitudinal movement of the slide 4. A transmission shaft 12 is provided in the anti-roll frame 10, which is parallel to the length direction of the translation beam 1 and passes under the slide 4. A second gear 11 corresponding to the slide 4 is provided on the transmission shaft 12. The slide 4 is provided with a second rack 9 meshing with the second gear 11, to drive the slide 4 longitudinally, and to change the spacing of the V-shaped fixture 14 to adapt to the lengths of different shaft workpieces 3.

[0028] The rotation of the transmission shaft 12 drives the rotation of the plurality of second gears 11 to realize the linkage of the slide 4. In order to perform automatic adjustment, a third motor 8 is also required to be installed to drive the transmission shaft 12 to rotate, such as Figure 3 As shown, the transmission shaft 12 is driven to rotate by using the third motor 8 and the chain sprocket assembly.
