The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as limiting the utility model. On the contrary, the embodiments of the utility model include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0019] The machine case fillet polishing device of the embodiments of the utility model is described below in combination with the drawings.

[0020] As Figures 1-3 shown, the machine case fillet polishing device of the embodiments of the utility model can include a support platform 10, a polishing assembly 20, a telescopic mechanism 30 and a limiting mechanism 40.

[0021] Among them, the support platform 10 is provided with a chip removal port 11, and the polishing assembly 20 can include a support plate 21, a polishing mechanism 22 and a drive mechanism 23.

[0022] Among them, the support plate 21 is rotatably arranged on the support platform 10 near one side of the chip removal port 11, and one end of the support plate 21 is provided with an opening 12, wherein the opening end of the support plate 21 extends above the chip removal port 11.

[0023] The polishing mechanism 22 is arranged on the support plate 21 near the opening 12, the drive mechanism 23 is arranged on the support plate 21, and the output end of the drive mechanism 23 is connected with the polishing mechanism 22 through the belt drive mechanism 13. It should be noted that the drive mechanism 23 described in this embodiment can be a driving motor.

[0024] One end of the telescopic mechanism 30 is pivotally connected with the support table 10, and the other end of the telescopic mechanism 30 is pivotally connected with the other end of the support plate 21. The limiting mechanism 40 is movably arranged on the support table 10 and located on the other side of the chip removal opening 11.

[0025] It should be noted that the telescopic mechanism 30 described in this embodiment can be a pneumatic cylinder, a hydraulic cylinder or an electric telescopic rod.

[0026] In order to clearly illustrate the above embodiment, in an embodiment of the present application, as shown in Figure 1 and Figure 3 , the polishing mechanism 22 can include a sliding seat 221, a spring 222, two supporting rollers 223, an adjusting roller 224 and an annular abrasive belt 225.

[0027] The sliding seat 221 is slidably arranged in the slide 14. The spring 222 is arranged in the slide 14, and one end of the spring 222 is fixedly connected with the sliding seat 221, and the other end of the spring 222 is fixedly connected with the end wall of the slide 14.

[0028] The two supporting rollers 223 and the adjusting roller 224 are distributed in a triangular shape around the opening 12. The two supporting rollers 223 are symmetrically and rotatably arranged on the support plate 21, and the rotating shaft of one of the two supporting rollers 223 is connected with the output end of the driving mechanism 23 through the belt transmission mechanism 13. The adjusting roller 224 is rotatably arranged on the sliding seat 221. The annular abrasive belt 225 is sleeved on the two supporting rollers 223 and the adjusting roller 224.

[0029] It should be noted that the belt transmission mechanism 13 described in this embodiment can include two pulleys and a belt. One of the two pulleys is sleeved and fixed on the rotating shaft of one of the two supporting rollers 223, and the other pulley is sleeved and fixed on the output end of the driving mechanism 23. The belt is sleeved on the two pulleys.

[0030] It can be understood that the staff can drive one of the supporting rollers 223 to rotate by controlling the driving mechanism 23 to drive the belt transmission mechanism 13. The rotating supporting roller 223 drives the other supporting roller 223 and the adjusting roller 224 to rotate synchronously through the annular abrasive belt 225. Then the case corner is polished through the rotating annular abrasive belt 225.

[0031] Further, in an embodiment of the present application, as shown in Figure 1 and Figure 3 , the limiting mechanism 40 can include a sliding plate 41, two sliding blocks 42, a threaded rod 43, a driving handle 44 and two positioning columns 45.

[0032] The support table 10 is provided with a first sliding groove 15 corresponding to the opening 12, and the sliding plate 41 is slidingly arranged in the first sliding groove 15, and the sliding plate 41 is provided with a second sliding groove 16.

[0033] The two sliding blocks 42 are symmetrically and slidingly arranged in the second sliding groove 16, the threaded rod 43 is rotationally arranged in the second sliding groove 16, and one end of the threaded rod 43 penetrates out of the second sliding groove 16 and is fixedly connected with the driving handle 44, wherein the threaded rod 43 has two sections of threads with opposite directions, and the two sections of threads are respectively threadedly connected with the corresponding sliding blocks 42.

[0034] Specifically, when the machine case corner needs to be polished, the relevant staff can first put the machine case on the two positioning columns 45, and then the staff drives the threaded rod 43 to rotate through the driving handle 44, the rotating threaded rod 43 drives the two sliding blocks 42 to move away from each other along the second sliding groove 16, and the two sliding blocks 42 respectively drive the positioning columns 45 to move towards the opposite corners of the machine case, so that the machine case is fixed and positioned through the movement of the two positioning columns 45 towards the opposite corners of the machine case.

[0035] At the same time, the staff controls the driving mechanism 23 to drive the belt transmission mechanism 13 to drive one of the supporting rollers 223 to rotate, and the rotating supporting roller 223 drives the other supporting roller 223 and the adjusting roller 224 to synchronously rotate through the annular abrasive belt 225.

[0036] Then, the staff pushes the sliding plate 41 to drive the machine case to move towards the annular abrasive belt 225, so that the corner of the machine case contacts the annular abrasive belt 225 and exerts a certain pressure on the annular abrasive belt 225, so that the annular abrasive belt 225 wraps the corner of the machine case at a certain angle. When the annular abrasive belt 225 is pressed, the annular abrasive belt 225 drives the sliding block 221 to move along the slide 14 and compresses the spring 222. When the corner of the machine case contacts the annular abrasive belt 225, the annular abrasive belt 225 polishes the corner of the machine case.

[0037] Then, the staff can control the output end of the telescopic mechanism 30 to reciprocatingly extend and retract, and drive the supporting plate 21 to reciprocatingly swing, and the reciprocatingly swinging supporting plate 21 drives the annular abrasive belt 225 to synchronously swing, so as to polish the corner of the machine case.

[0038] In summary, the machine case corner polishing device can automatically polish the corner of the machine case, without the need for excessive manual operation, which not only ensures the uniformity and consistency of polishing, but also improves the polishing efficiency.
