Description

Technical Field

[0001] The utility model relates to the technical field of machine tool protection, in particular to a machine tool protective cover. Background Art

[0002] A machine tool is a machine that uses cutting to process metal blanks into machine parts. Since its internal parts are relatively delicate, a machine tool protective cover is required to protect its internal linear guides, ball screws or transmission racks from external corrosion and damage.

[0003] Existing machine tool protective covers will produce a lot of debris and some waste liquid after use. The accumulation of garbage over time will cause damage to internal parts, so it is necessary to clean the inside of it frequently. Since most machine tool protective covers are of one-piece design, it is difficult to disassemble and clean them, and maintenance is difficult, which affects the subsequent work and has low practicality.

[0004] Moreover, most of the existing machine tool protective covers are equipped with visible windows to facilitate the staff to observe the internal operating conditions. However, during operation, a lot of debris and waste liquid will adhere to the window surface, which greatly affects the staff's observation and makes it impossible to make timely adjustments to internal changes. It is very easy to cause errors in the manufactured parts, which is extremely unstable. Utility Model Content

Side plates 3 are fixedly connected to both ends of the base frame 1. The protective shell 2 and the side plates 3 are used together to protect the machine tool inside, and can also prevent the debris and waste liquid generated during the internal processing from spreading outward to cause environmental pollution. A bearing shell 4 is fixedly connected to the surface of one side of the base frame 1 to effectively prevent the parts inside from being damaged by external forces, ensuring that the protective cover is more stable when in use. Expansion mechanisms 5 are installed inside the two sides of the base frame 1, and one side of the expansion mechanism 5 is installed on the bearing shell 4, the inner wall of the carrying shell 4 is fixedly connected with a fixing block 6, and the fixing block 6 can fix one side of the expansion mechanism 5 to the inside of the carrying shell 4 to prevent it from falling off from the inside of the carrying shell 4 during operation, ensuring that its internal parts are more stable during operation. A motor 7 is installed on one side of the carrying shell 4, and the output shaft of the motor 7 is used in conjunction with the expansion mechanism 5. Under the action of the motor 7, the motor 7 can be translated and expanded to both sides at the same time, and the protective shell 2 can be translated to both sides, which can make it more convenient to clean and repair the inside of the machine tool. At the same time, when the protective shell 2 is translated, the side plate 3 can scrape off the debris and stains on the inner wall of the protective shell 2 to prevent excessive debris and stains from affecting the machine tool. A door frame 8 is hinged on one side of the protective shell 2. The outer side of the door frame 8 is designed with a handle, which can facilitate the staff to clean or adjust the interior. An acrylic plate 9 is arranged inside the door frame 8, so that the staff can observe the operation of the protective cover at any time when the machine tool is working, which effectively improves the practicality. Slide grooves 10 are opened on both sides of the interior of the door frame 8. A cleaning mechanism 11 is installed inside the slide groove 10. The slide groove 10 on one side is designed in a Z shape, which can effectively prevent the machine from The debris and waste liquid generated during the operation of the bed are seeped out, and the chute 10 is used in conjunction with the cleaning mechanism 11. Under the action of the cleaning mechanism 11, the acrylic plate 9 on one side thereof can be cleaned, and the debris and waste liquid attached to the surface of the acrylic plate 9 can be swept and scraped off, ensuring that the staff can clearly observe the inside of the protective cover. A storage box 12 is provided inside the door frame 8, and the storage box 12 is used in conjunction with the cleaning mechanism 11. The cleaning mechanism 11 will scrape the debris and waste liquid into the storage box 12, so as to achieve centralized collection of garbage, which is more convenient for the staff to clean up.

[0024] The expansion mechanism 5 includes a transmission rod 51, which is rotatably connected to the inside of the fixed block 6. One end of the transmission rod 51 passes through the inner wall of the bearing shell 4 and is fixedly connected to the output shaft of the motor 7 and is rotatably connected to the penetration. Both ends of the transmission rod 51 are fixedly connected to a bevel gear set 52, and one side of the bevel gear set 52 is fixedly connected to a bidirectional threaded rod 53. The transverse gear in the bevel gear set 52 is fixedly connected to both ends of the transmission rod 51 and aligned with its center point. A vertical gear is meshed on one side of the transverse gear, and the center of the vertical gear is fixedly connected to one side of the bidirectional threaded rod 53. The motor 7, the transmission rod 51, The bevel gear set 52 is used in conjunction with the two-way threaded rod 53. Under the action of the motor 7, the transmission rod 51 can be rotated, and the bevel gear sets 52 at both ends can be driven to move, so that the two-way threaded rod 53 fixedly connected to the bevel gear sets 52 on both sides can be rotated at the same time. Under this action, the problem of poor stability of the main body caused by the inconsistent rotation speed of the two-way threaded rod 53 on both sides can be prevented. Moving blocks 54 are threadedly connected on both sides of the surface of the two-way threaded rod 53. Under the action of the rotation of the two-way threaded rod 53, it can follow it to translate to both sides, and has higher stability during operation.

[0025] The cleaning mechanism 11 includes a sliding rod 111, which is slidably connected to the inner wall of the slide groove 10. A wiper blade 112 is fixedly connected to one side of the sliding rod 111. The wiper blade 112 is made of rubber. The surface of the wiper blade 112 is slidably connected to the surface of the acrylic plate 9. A brush 113 is fixedly connected to one side of the sliding rod 111. The wiper blade 112 and the brush 113 are used together. The brush 113 first sweeps away the metal debris attached to the surface of the acrylic plate 9, and then the wiper blade 112 scrapes the remaining waste liquid and other liquids into the interior of the storage box 12, which are cleaned together by the staff. A handle 114 is fixed to one side of the sliding rod 111, which enables the staff to more conveniently operate the internal cleaning mechanism 11, which has certain practicality.

[0026] It is worth noting that: the technical scheme proposes that the technical features such as the motor 7 should be regarded as the prior art, and the specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected by conventional methods in the field, and this technical scheme will not be further elaborated.

[0027] Working principle: First, connect the protective cover to the machine tool for use. When the debris and waste liquid generated by the internal machine tool during operation adhere to the inside of the acrylic plate 9, then pull the handle 114 to make the sliding rod 111 slidably connected to the slide groove 10 move downward, and at the same time, the wiper blade 112 and the brush 113 arranged on one side of the sliding rod 111 will clean and scrape the debris and waste liquid on the surface of the acrylic plate 9, and the scraped garbage will fall into the inside of the storage box 12 and be cleaned by the staff. When there is a lot of garbage inside the machine tool and maintenance is required, first start the motor 7 to drive the transmission rod 51 on one side to rotate, and then the transmission rod 51 drives the bevel gear set 52 on both sides to move, and finally the bevel gear set 52 will cause the two-way threaded rods 53 on both sides to rotate at the same time, and drive the protective shell 2 and the moving block 54 to expand to both sides, and finally the inside of the machine tool can be cleaned and repaired.
