Technical Field

[0001] This utility model relates to the field of machine tool protective cover technology, and in particular to an armor-type machine tool protective cover. Background Technology

[0002] Protective covers are widely used to protect machine tools during operation. Machine tools are machines that manufacture machinery and play a vital role in the modernization of the national economy. Lathes are machine tools that mainly use cutting tools to turn rotating workpieces. Drills, reamers, and other cutting tools can also be used on lathes for corresponding machining. Protective covers are also used in the operation of machine tools.

[0003] Most existing protective covers are integrally molded and fixedly installed above the machine tool to prevent debris generated during machine processing from flying out, thus protecting the machine tool from the external environment.

[0004] However, in the use of existing protective covers, most of the armor blades are molded as a single piece. When a section is damaged, the entire protective cover will be scrapped, increasing the cost of use. To address the above problems, an armor-type machine tool protective cover is proposed. Utility Model Content

[0013] By adopting the above technical solution, the second slide rail can limit the pull plate and prevent it from deviating when moving.

[0014] As a further description of the above technical solution: a rubber block is fixedly connected to one end of the pull plate.

[0015] By adopting the above technical solution, the rubber block can reduce vibration of the pull plate.

[0016] As a further description of the above technical solution: limit grooves are provided on both the left and right sides of the outer wall of the mounting plate, and limit blocks are slidably connected to the inner walls of the two limit grooves.

[0017] By adopting the above technical solution, the limiting groove can limit the limiting block and prevent the moving plate from shifting when it moves.

[0018] As a further description of the above technical solution: the top of the rack is engaged with a first gear.

[0019] By adopting the above technical solution, the rack can limit the first gear, so that the first gear moves while rotating.

[0020] As a further description of the above technical solution: push blocks are fixedly connected to both the left and right sides of the outer wall of the mounting plate, and the push blocks and the stop blocks are engaged.

[0021] By adopting the above technical solution, the mounting plate can drive the push block to move, and the push block and the stop block can fix the mounting plate and the moving plate.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model provides an armor-type machine tool protective cover. First, by pulling a pull plate through a stop block, connecting plate, stop block, and limiting block, the U-shaped plate is squeezed. The connecting plate pushes the stop block to release the push block's engagement. The pull plate is then pulled further to fix the U-shaped plate, allowing for quick disassembly of damaged telescopic plates. The moving plate drives the limiting block into the limiting groove, and the push block squeezes the stop block, compressing the spring. When the push block is fully inserted into the square groove, the spring rebounds, and the push block and stop block engage, thus enabling quick installation of the first telescopic plate. This facilitates replacement of damaged parts and reduces operating costs.

[0024] 2. The armor-type machine tool protective cover provided by this utility model consists of an active bevel gear, a driven bevel gear, a laser rangefinder, and a first gear. A starting motor drives the active and driven bevel gears to rotate, thereby driving the first gear to rotate. Under the limitation of the rack, the first gear can rotate while driving the laser rangefinder to move. The laser rangefinder can detect the distance between the square plate and the first gear, thereby detecting the extension distance between the first and second telescopic plates, realizing the automatic opening and closing of the first and second telescopic plates, and improving the safety of use.

The driven bevel gear 17 can drive the first gear 19 to rotate. Under the limit of the rack 6, the first gear 19 can rotate and move at the same time. When the first gear 19 moves, it drives the laser rangefinder 18 to move. The signal receiver 5 receives the signal from the laser rangefinder 18. The laser rangefinder 18 can detect the distance between the square plate 3 and the first gear 19, thereby detecting the telescopic distance between the first telescopic plate 10 and the second telescopic plate 11, realizing the automatic opening and closing of the protective cover, improving the safety and effectiveness of use. When the second telescopic plate 11 and the mounting plate 12 move, they drive the first wheel 15 and the second wheel 21 to move, which can reduce the friction between the second telescopic plate 11 and the mounting plate 12 during movement and improve the effectiveness of use.
