Detailed Embodiment

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-4 , the present invention provides a technical solution for a deburring device used for a casing. The present invention will be further described in detail below in conjunction with the drawings.

[0027] Embodiment 1:

[0028] A deburring device used for a casing includes a rotating rod 1. The rear end of the rotating rod 1 is connected to the output end of a motor. The motor drives the rotating rod to rotate, and then drives the structures at the front to rotate for inner wall polishing. There is a mounting plate at the rear of the motor. A pressing cylinder is provided at the rear of the mounting plate. The output end of the pressing cylinder is provided with a telescopic rod, and the other end of the telescopic rod is connected to one side of the mounting plate.

[0029] Further, a fixed ring 2 and a movable ring 3 are provided at the front end of the rotating rod 1. Fixed seats 4 are correspondingly provided on the outer circles of the fixed ring 2 and the movable ring 3. The inner cavity of the fixed seat 4 is connected with cross struts 5 through connecting shafts. A polishing plate 6 is provided at the outer end of the cross strut 5. The outer end of the cross strut 5 is connected with the support in the polishing plate 6 through a transverse shaft. A central shaft strut 7 is provided at the cross position in the middle of the two groups of cross struts 5. A guide plate 8 is provided at the front end of the polishing plate 6. A stop block 9 is provided on the outer circle of the rotating rod 1 at the rear of the movable ring 3. A first spring 10 is provided between the movable ring 3 and the stop block 9.

[0030] Specifically, the guide plate 8 is fixedly connected to the front end of the polishing plate 6, and the front end of the guide plate 8 inclines inward.

[0031] During specific use, as Figure 1 、 Figure 2 shown, when polishing the inner wall of the plastic pipe, first use the clamping device to fix the plastic pipe fitting. The axis of the clamped plastic pipe fitting is concentric with the axis of the rotating rod 1. Plug in the power plug of the pressure cylinder and start it. The pressure cylinder drives the telescopic rod to extend forward, pushing the mounting plate, the motor, the rotating shaft 1 and the polishing mechanism forward to extend into the pipe orifice of the plastic pipe. When the diameter of the pipe orifice is smaller than the diameter enclosed by the four groups of polishing plates 6 as in Figure 1 and Figure 2 , the guide plate 8 will first enter the pipe orifice, and then as it is pushed inward, the guide plate 8 is squeezed to drive the polishing plate 6 to be squeezed and contracted. During the contraction process, the movable ring 3 moves backward and compresses the first spring 10 until the entire polishing plate enters the plastic pipe. Then, connect the power supply of the motor and start it. The motor drives the rotating rod 1 to rotate, then drives the fixed ring 2 and the movable ring 3 to rotate, and then drives the polishing plate 6 to rotate. At the same time, along with the forward push of the telescopic rod, the polishing of the pipe wall is completed.

[0032] Embodiment 2:

[0033] Based on Embodiment 1, a deburring device for a casing includes a rotating rod 1. A second spring 11 is sleeved between the fixed ring 2 and the movable ring 3 on the outer circle of the rotating rod 1. One end of the second spring 11 is connected to the fixed ring 2, and the other end is connected to the movable ring 3. Equal-sized limiting grooves 12 are opened in the upper part of the front end of the rotating rod 1. The limiting grooves 12 are continuously opened and are in the shape of long strip-shaped corrugated grooves, and can be limited and fixed at any position.

[0034] Specifically, a push rod 13 is provided at the rear of the movable ring 3. A through threaded groove 14 is opened in the upper part of the push rod 13. A threaded bolt 15 is threadedly connected to the inner cavity of the through threaded groove 14. The radius of the main rod of the threaded bolt 15 is equal to the radius of the limiting groove 12.

[0035] During specific use, as Figure 1 、 Figure 3 andFigure 4 As shown, in Embodiment 1, it can be known that when the diameter of the pipe orifice is smaller than the diameter enclosed by the polishing plate 6, the enclosed diameter of the polishing plate 6 can be automatically adjusted by the extrusion of the guiding plate 8 and the inner wall can be polished. At this time, the lower end of the threaded bolt 15 is in a separated state from the limiting groove 12. After the polishing is completed, the polishing mechanism disengages from the pipe orifice. Due to the arrangement of the first spring 10 and the second spring 11, the elastic force of the springs will drive the push rod 13 to reset, and then drive the polishing plate 6 to return to the initial position. When the diameter of the pipe orifice is larger than the diameter enclosed by the polishing plate 6, it is necessary to manually push the push rod 13 forward, and then drive the cross struts 5 at the front to change the angle, and then drive the polishing plate 6 to expand outwards, so that the diameter enclosed by the polishing plate 6 becomes larger until the outer wall of the polishing plate 6 is in contact with the inner wall of the pipe orifice and then stop. Then tighten the threaded bolt 15 so that the lower end of the threaded bolt 15 is inserted into the limiting groove 12, and then repeat the steps of the rotation of the rotating rod 1 and the pushing of the telescopic rod in Embodiment 1 to polish the inner wall of the plastic pipe. When the polishing is completed, turn off the motor, and then take out the polishing mechanism from the pipe orifice through the telescopic rod.
