Description

Technical Field

[0001] The utility model relates to the technical field of round tube internal polishing machines, in particular to a translational lifting material rack for unloading materials of a multi-head round tube internal polishing machine. Background Art

[0002] The round tube internal polishing machine is a mechanical equipment used for polishing and rust removal of round tubes. It is mainly used for rust removal and polishing in industries such as hardware manufacturing, vehicle accessories, steel and wood furniture, instrument machinery, standard parts, and before and after electroplating. It relies on mechanical force to make the workpiece being polished obtain a certain degree of roughness to reduce the roughness value and friction resistance of the part surface; at the same time, due to the heat generated during the grinding process, it plays a lubricating role, thereby improving the wear resistance and fatigue resistance of the workpiece. The processed workpiece has high brightness and will not affect the original size of the workpiece. It is suitable for finishing processing of various round metal pipe fittings. The complete set of production line equipment is mainly composed of three parts: polishing machine, feed rack, and discharge rack.

[0003] When the existing internal polishing machine is grinding and polishing the pipe fittings, in order to ensure the flatness of the polishing, the pipe fittings usually move forward at a uniform speed. However, during the processing, the unloading of the round tube is not convenient enough. The pipe fittings that have been processed are only pushed down by the movement of the subsequent round tubes, which is easy to cause the rack to be blocked and affect the transportation of the subsequent round tubes. At the same time, due to the limitations of the production process, the inner wall thickness of the round tubes is different. Therefore, during the polishing process, the round tubes moving at a uniform speed are difficult to ensure that the inner wall of the pipe fittings maintains the same flatness, which reduces the quality and efficiency of polishing. In view of this, the present application proposes a translational lifting rack for unloading of a multi-head round tube internal polishing machine. Utility Model Content

[0023] A plurality of support plates 5 are fixedly connected between corresponding side walls of the two support plates 4 . The support plates 5 are all arc-shaped plates, and the angles of the support plates 5 correspond to those of the arc-shaped grooves 3 .

[0024] By providing two arc grooves 3 and a plurality of support plates 5, after the round tube is polished, the round tube can be transported to the frame 1 during the operation of the polishing machine, and the unloading is completed under the turning of the movable plate 16.

[0025] Among them, the driving device includes a driving box 13, and the driving box 13 is fixedly installed on the supporting leg 2. A driving motor is installed in the driving box 13. The output end of the driving motor is connected to a pulley 11 through a belt 12. A transmission rod 10 is penetrated through the pulley 11. The transmission rod 10 is penetrated and connected to multiple second shaft seats 8, and the transmission rod 10 is key-connected to multiple driving wheels 9.

[0026] The output end of the driving motor drives the belt 12 and the pulley 11 to operate, and finally the transmission rod 10 rotates synchronously, thereby driving the multiple driving wheels 9 connected through the rotation, and the round tubes on the frame 1 are translated and transported.

[0027] The unloading device includes a connecting rod 15 , on which a plurality of movable plates 16 are arranged. The plurality of movable plates 16 are rotatably connected to the side walls of the frame body 1 through rotating shafts 17 .

[0028] Among them, the connecting rod 15 includes a horizontal rod and multiple vertical rods, and the horizontal rod and the multiple vertical rods are fixedly connected. The tops of the multiple vertical rods are rotatably connected to the lower surfaces of the corresponding movable plates 16. The multiple movable plates 16 are all configured as arc-shaped plates and correspond to the angle of the support plate 5.

[0029] By limiting one end of the movable plate 16 through the rotating shaft 17, the telescopic end of the hydraulic cylinder 14 can drive the movable plate 16 to flip around the rotating shaft 17 as the axis, so that the round tube moved above the movable plate 16 is moved upward out of the frame 1 and finally falls onto the guide plate 25.
