[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The fixed guide rail 102 is fixed to the top of the mounting column 101, and the extension guide rail 103 is slidably connected to the fixed guide rail 102 through a sliding member and is distributed above the fixed guide rail 102. The mounting column 101, the fixed guide rail 102, and the extension guide rail 103 are provided in two groups;

[0036] The rear protective cover 105 and the front protective cover 104 are respectively fixed to the top of the two extension guide rails 103, and the rear protective cover 105 and the front protective cover 104 are symmetrically arranged. The observation window 106 is embedded in the inner side of the front protective cover 104. The front protective cover 104 is provided with a cleaning component 2 for scraping the observation window 106;

[0037] The cleaning component 2 includes a wall scraping unit, a driving unit, and a limiting unit;

[0038] The scraping unit is used to scrape the surface of the lathe processing position where the observation window 106 faces;

[0039] The drive unit is used to provide power for the operation of the scraper unit;

[0040] The limiting unit is used to provide limiting and guiding for the moving operation of the driving unit;

[0041] The scraping unit includes a convex fixed column 201, a rotating sleeve 204, and a scraper 205;

[0042] The convex fixing post 201 is fixed to one end surface of the front protective cover 104 near the lathe processing position, and the convex fixing post 201 is distributed on one side of the observation window 106. The rotating sleeve 204 is rotatably connected to the outer side of the convex fixing post 201, and the scraper 205 is fixed to the top of the rotating sleeve 204.

[0043] The rotating sleeve 204 rotates around the convex fixed column 201 to drive the scraper 205 to swing and scrape the surface of the observation window 106;

[0044] The driving unit includes a through hole 202, a driven guide block 206, a linkage rod 207, a reciprocating guide groove 208, a limiting circular block 210, a pressing block 211, and a compression spring 212;

[0045] The through hole 202 extends from one end of the convex fixing column 201 to the front end protective cover 104. The linkage rod 207 is slidably connected to the inside of the through hole 202 and extends to the front end protective cover 104 and the outside of the driven guide block 206. The limiting round block 210 and the pressing block 211 are respectively fixed to the two ends of the linkage rod 207. The limiting round block 210 is attached to the outer end of the driven guide block 206.

[0046] The compression spring 212 is sleeved on the outside of the linkage rod 207 and is distributed between the pressing block 211 and the front protective cover 104;

[0047] The reciprocating guide groove 208 is provided on the outside of the linkage rod 207 , and the driven guide block 206 is fixed on the inside of the driven guide block 206 and is slidably connected to the inner wall of the reciprocating guide groove 208 ;

[0048] When the linkage rod 207 moves along the inner wall of the through hole 202, the reciprocating guide groove 208 cooperates with the driven guide block 206 to realize the reciprocating rotation of the rotating sleeve 204, which is used to provide power for the reciprocating swing of the scraper 205;

[0049] The reciprocating guide groove 208 is composed of multiple sections of spiral grooves. The number of spiral turns of each section of the spiral groove is a quarter of a turn, and the spiral directions of two adjacent spiral grooves are opposite.

[0050] In this embodiment, it should be noted that the sliding connection structure between the extension rail 103 and the fixed rail 102 is a prior art and has nothing to do with the solution improvement, so it is not described in detail.

[0051] When in use, the protective assembly 1 is mounted on the top of the lathe housing via the mounting post 101. The front and rear protective covers 104 and 105 can then slide to the machining area of ​​the lathe via the extended guide rails 103 to intercept the chips and cutting fluid generated during machining, achieving a protective effect. The observation window 106 allows the operator to observe the machining operation of the lathe.

[0052] When too much debris adheres to the surface of the observation window 106 and the cutting fluid causes blurred vision, the observation window 106 can be scraped and cleaned by the cleaning component 2. The operation steps are as follows:

[0053] By manually pressing the pressing block 211 to make it move closer to the front end protective cover 104, the pressing block 211 squeezes the compression spring 212 to further contract, and at the same time pushes the linkage rod 207 to move. Since the driven guide block 206 is slidably connected to the reciprocating guide groove 208, during the movement of the linkage rod 207, the driven guide block 206 will reciprocate in the track of the inner wall of the reciprocating guide groove 208, so that the reciprocating rotation of the rotating sleeve 204 can be achieved. The rotating sleeve 204 drives the scraper 205 to swing back and forth, and the swinging scraper 205 contacts the surface of the observation window 106 to scrape and clean the wall of the observation window 106 (it should be supplemented that the number of spiral turns of the spiral groove is a quarter of a turn, which is used to make the angle of the scraper 205 swinging 90 degrees in a single time);

[0054] After the pressing block 211 is pressed to the bottom, the pressing of the pressing block 211 is released, and the pressing block 211 and the linkage rod 207 are reset under the elastic force of the compression spring 212. During this process, the scraper 205 still swings back and forth, thereby restoring the clarity of the observation window 106.

[0055] Please refer to Figures 1 to 4 , the limiting unit includes a fixed limiting block 203 and a linear guide groove 209;

[0056] The linear guide groove 209 is provided outside the linkage rod 207 and close to the pressing block 211. The fixed stop block 203 is fixed to one end of the outer wall of the mounting column 101, and the fixed stop block 203 is slidably connected to the inner wall of the linear guide groove 209.

[0057] The fixed limit block 203 cooperates with the linear guide groove 209 to provide limit and guidance for the movement of the linkage rod 207;

[0058] The compression spring 212 is always in a compressed state, and the compression spring 212 is located outside the fixed limit block 203 , and the outside of the pressing block 211 is covered with a rubber layer.

[0059] In this embodiment, during the movement of the linkage rod 207, the linear guide groove 209 cooperates with the fixed limit block 208, so that the linkage rod 207 can only move but cannot rotate, thereby ensuring the stable cooperation between the reciprocating guide groove 208 and the driven guide block 206;

[0060] The compression spring 212 is always in a compressed state, so that the compression spring 212 always exerts a thrust on the linkage rod 207, thereby keeping the scraper 205 in a stable storage state.

[0061] The rubber layer covering the outer side of the pressing block 211 can buffer the collision between the pressing block 211 and the fixed limiting block 203 .

[0062] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
