Description

Technical Field

[0001] This utility model relates to the field of sawing machines, and in particular to a protective sawing machine for processing aerospace sheet metal. Background Technology

[0002] When cutting aerospace sheet metal, a blade saw is usually used. A blade saw typically consists of a machine base, a drive mechanism, and a saw blade. The saw blade is mostly protected by a protective shell, so that the exposed part of the saw blade is used for cutting.

[0003] However, the exposed portion of the saw blade on existing saw blade machines is much larger than the thickness of the aerospace sheet metal. This poses a safety hazard to workers during cutting operations. Furthermore, since the existing protective housing is of fixed size and installed in a fixed position on the saw blade machine, it is not convenient to adjust the exposed portion of the saw blade according to the thickness of the aerospace sheet metal, thus presenting certain defects. Utility Model Content

[0004] The purpose of this invention is to provide a protective saw for processing aerospace sheet metal, so as to solve the problems mentioned in the background art.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] This utility model provides, for example Figure 1-2 The protective saw shown is for processing aerospace sheet metal, including a saw blade saw 1, a protective housing 2, a protective frame 3, a locking assembly 4, and a guide assembly 5. The saw blade saw 1 is equipped with a saw blade for cutting aerospace sheet metal. The saw blade saw 1 also includes a drive motor, a driven disc, and a drive disc. The saw blade is mounted outside the driven disc and the drive disc, so that the drive motor drives the drive disc to rotate, thereby driving the saw blade to move and cut the aerospace sheet metal. This is existing technology and will not be described in detail here. The protective housing 2 is mounted on the saw blade saw 1 and fits over the saw blade. The protective housing 2 is installed using a hinged latch, allowing it to be rotated and opened for easy replacement and maintenance of the saw blade. The protective frame... The outer wall of the protective frame 3 is slidably inserted into the protective housing 2. A slot corresponding to the saw blade is opened on one side of the protective frame 3. When the protective housing 2 is rotated open, the protective housing 2 can drive the protective frame 3 to move, thereby separating the protective frame 3 from the saw blade through the slot. The locking component 4 is set between the protective housing 2 and the protective frame 3. The locking component 4 is used to lock the height of the protective frame 3, thereby ensuring the stability of the position of the protective frame 3. When the locking component 4 is released from the restriction of the protective frame 3, the protective frame 3 can be slid, thereby changing the distance between the bottom of the protective frame 3 and the support table on the saw blade sawing machine 1, thereby changing the exposed length of the saw blade. The guide component 5 is installed inside the protective frame 3 on the side opposite to the slot. The guide component 5 is used to guide the saw blade.

[0036] Furthermore, the locking assembly 4 includes a locking screw 41 and a locking nut 42. The locking screw 41 is located on the protective housing 2, and the locking nut 42 is threaded to the outside of the locking screw 41. The locking nut 42 is located inside the protective frame 3, so that the protective frame 3 can be locked by tightening the locking screw 41 and the locking nut 42.

[0037] Furthermore, the locking assembly 4 also includes a first fixing plate 44 and a second fixing plate 45. The first fixing plate 44 is slidably sleeved on the outside of the locking screw 41, and one side of the second fixing plate 45 is fixedly connected to the locking nut 42. The second fixing plate 45 is slidably snapped into the inside of the protective frame 3. The locking assembly 4 also includes a connecting groove 43, a sliding hole, and a guide rod 46. The connecting groove 43 is opened on the front of the protective housing 2, and the sliding hole is opened on the front of the protective frame 3. Thus, when the protective frame 3 slides, the protective frame 3 can slide relative to the locking screw 41 through the sliding hole. One end of the guide rod 46 is fixedly connected to the first fixing plate 44, and the other end of the guide rod 46 passes through the connecting groove 43 and the sliding hole and is slidably sleeved with the second fixing plate 45. Under the action of the guide rod 46, the second fixing plate 45 and the locking nut 42 can be prevented from rotating, that is, when the locking screw 41 is tightened or loosened, the locking nut 42 will not rotate.

[0038] Example 2

[0039] Based on Example 1, such as Figure 3 As shown, the guide assembly 5 includes a connecting block 51, a second guide collar 53, a mounting screw 55, a mounting groove 54, and a first guide collar 52. The connecting block 51 is fixedly connected to the inside of the protective frame 3. The second guide collar 53 is rotatably mounted on one side of the connecting block 51 by the mounting screw 55. The second guide collar 53 is used to limit the side of the saw blade. The mounting groove 54 is opened on one side of the connecting block 51. The first guide collar 52 is rotatably mounted in the mounting groove 54 by the mounting screw 55. The first guide collar 52 is used to guide and limit the back side of the saw blade, that is, to limit the side of the saw blade without the locking teeth. Under the action of the first guide collar 52 and the two second guide collars 53, the stability of the saw blade operation can be guaranteed.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
