For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] The present utility model provides the following technical solutions:

[0026] Embodiment 1, please refer to Figures 1-3, A trimming device for processing the top cover of a spacecraft, comprising a bottom plate 1. A console 4 is fixedly connected to the front side of the top of the bottom plate 1. A trimming mechanism 3 is fixedly connected to the rear side of the console 4 on the top of the bottom plate 1. An adjusting mechanism 2 is installed behind the trimming mechanism 3;

[0027] The trimming mechanism 3 includes a support bar 36. The support bar 36 is fixedly connected to the top of the bottom plate 1. A first cutting knife 37 is fixedly connected to the front side of the support bar 36. Sliding frames 38 are fixedly connected to both sides of the support bar 36. A sliding bar 35 is slidably connected to the vicinity of the middle of the sliding frames 38. A second cutting knife 39 is fixedly connected to the front side of the sliding bar 35. The middle of the top of the sliding bar 35 is fixedly connected to a hydraulic telescopic cylinder 381. The top of the hydraulic telescopic cylinder 381 is fixedly connected to the top of the sliding frame 38. A first stabilizing rod 32 is fixedly connected to the inner top of the sliding frame 38 near one side. A stabilizing block 33 is slidably connected to the vicinity of the bottom of the first stabilizing rod 32.

The bottom end of the second stabilizing rod 31 is fixedly connected to the top of the sliding bar 35. A fixed sleeve 34 is fixedly connected to the sliding frame 38 on the top of the sliding bar 35.

[0028] By setting the trimming mechanism 3, the blank part of the spacecraft top cover is placed on the top of the console 4, and then the rough edge is pushed to the bottom of the first cutting knife 37. At this time, the distance plate 25 with the adjusted distance contacts the rough edge of the spacecraft top cover blank part. Thus, when the hydraulic telescopic cylinder 381 works downward and drives the second cutting knife 39 and the first cutting knife 37 to approach for trimming, it can cut out an edge with a neat distance as required, effectively solving the problem that the current trimming device cannot be adjusted according to the required trimming distance and cannot ensure the neatness of the edge after trimming.

[0029] The first stabilizing rod 32 and the second stabilizing rod 31 can, with the cooperation of the stabilizing block 33, ensure that the first cutting knife 37 and the second cutting knife 39 always maintain a linear movement distance. Under the condition of the linear movement distance maintained by the sliding frame 38, it provides a dual guarantee for the purpose of the linear movement trajectory, thereby being able to long-term ensure the purpose of neat trimming.

[0030] The first cutting knife 37 and the second cutting knife 39 are arranged corresponding to each other, and the first cutting knife 37 and the second cutting knife 39 have the same size.

[0031] Through holes are provided on both sides of the stabilizing block 33. The stabilizing block 33 is slidably connected to the first stabilizing rod 32 and the second stabilizing rod 31 respectively through the through holes on both sides.

[0032] Example two, please refer to Figures 1-4, and on the basis of the first embodiment, it is further obtained that the adjusting mechanism 2 includes a mounting plate 26, the mounting plate 26 is fixedly connected to the bottom of the fixed sleeve 34, a chute 22 is opened at the rear side of the mounting plate 26, an adjusting bolt 21 is arranged in the chute 22, the mounting plate 26 is fixedly connected with a top part 23 through the adjusting bolt 21, a support frame 24 is fixedly connected to the bottom of the top part 23, and a distance plate 25 is fixedly connected to the bottom of the support frame 24.

[0033] By means of the arranged adjusting mechanism 2, when adjusting the distance plate 25 as required, loosen the adjusting bolt 21. At this time, according to the distance of the chute 22, the whole support frame 24 is moved away from or close to the first cutting knife 37, and then tighten the adjusting bolt 21, so that the distance plate 25 can be close to and away from the first cutting knife 37, thereby ensuring that the burrs on the edges of different spacecraft top cover blank parts can be trimmed as required, and further achieving the purpose of good trimming neatness.

[0034] The size of the distance plate 25 is the same as that of the first cutting knife 37 and the second cutting knife 39, and the distance plate 25 is arranged at the rear side of the first cutting knife 37.

[0035] Through holes are opened on both sides of the mounting plate 26, the sliding rods of the sliding frame 38 pass through the through holes of the mounting plate 26, the top of the mounting plate 26 is fixedly connected to the bottom of the stabilizing block 33, and through holes for sliding are respectively opened on the mounting plate 26 corresponding to the first stabilizing rod 32 and the second stabilizing rod 31.

[0036] In the actual operation process, when this device is used, place the spacecraft top cover blank part on the top of the operating table 4, and then push the edge burr to the bottom of the first cutting knife 37. At this time, the distance plate 25 with the adjusted distance as required contacts the burr of the spacecraft top cover blank part. Thus, when the hydraulic telescopic cylinder 381 works downward and drives the second cutting knife 39 and the first cutting knife 37 to approach for trimming, an edge with a required neat distance can be trimmed, effectively solving the problems that the current trimming device cannot be adjusted according to the required trimming distance and cannot ensure the neatness of the trimmed edge.

[0037] The first stabilizing rod 32 and the second stabilizing rod 31 can, under the cooperation of the stabilizing block 33, ensure that the first cutting knife 37 and the second cutting knife 39 always maintain a linear movement distance. Under the condition of the linear movement distance maintained by the sliding frame 38, a dual guarantee for the linear movement track is provided, so as to be able to ensure the purpose of long-term trimming neatness.

[0038] When adjusting the distance plate 25 as needed, loosen the adjusting bolt 21. At this time, move the entire support frame 24 away from or closer to the first cutting knife 37 according to the distance of the sliding groove 22. Then tighten the adjusting bolt 21, and the distance plate 25 can be moved closer to and away from the first cutting knife 37, so as to ensure that the burrs on the edges of different spacecraft top cover blanks can be trimmed as needed, and further achieve the purpose of good and neat trimming.
