Description

Technical Field

[0001] The utility model relates to the field of numerical control machine tools, in particular to a protective cover for numerical control machine tools. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer curved surfaces of arbitrary taper angles, and cylindrical and conical threads. It can also perform grooving, drilling, reaming, and boring. CNC machine tools automatically process the parts according to pre-written processing programs. We compile the processing route, process parameters, tool motion trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then record the contents of this program sheet on the control medium, and then input it into the CNC device of the CNC machine tool to command the machine tool to process parts.

[0003] The protective cover in the existing technology is generally directly covered on the main body of the equipment. When the equipment is running, the debris, water stains and other waste materials will not pose a danger to the staff. In addition, the existing protective cover is also provided with an observation window to facilitate the operator to understand the processing status.

[0004] When the above-mentioned CNC machine tool protective cover is in use, debris and water stains will splash onto the observation window. Since the observation window cannot be cleaned automatically, a lot of waste will accumulate over time, making it impossible for the operator to observe the working conditions of the equipment in time. Therefore, this application proposes a CNC machine tool protective cover. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a protective cover for a CNC machine tool to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a CNC machine tool protective cover, comprising a protective cover body, a handle, and tempered glass, a fixed rod is installed on the inner wall of the protective cover body, and a limit plate is slidably installed on the fixed rod, a connecting plate is rotatably installed on the outer wall of the limit plate, and a soft rubber scraper for cleaning the tempered glass is installed on the outer wall of the connecting plate, an electric telescopic rod connected to the limit plate is fixedly installed on the inner wall of the protective cover body, a motor connected to the connecting plate is installed on the outer wall of the limit plate, and a start button corresponding to the motor is installed on the end of the limit plate, a baffle corresponding to the soft rubber scraper is installed on the bottom end of the fixed rod, and a waste box installed on the protective cover body is provided below the baffle, and a first fixed block and a second fixed block corresponding to the start button are installed on the inner wall of the protective cover body.

[0007] By adopting the above technical solution, under the action of the electric telescopic rod and the fixed rod, the limit plate can only move up and down in a fixed manner. When the limit plate moves downward, it will move the soft rubber scraper downward, thereby starting a cleaning effect on the tempered glass. When the soft rubber scraper drops to the lowest point, the second fixed block will contact the start button of the motor, thereby causing the connecting plate connected to the soft rubber scraper to deviate downward at a certain angle. At this time, the soft rubber scraper will contact the baffle, so that the waste is blocked by the baffle and falls into the waste box below.

[0008] Furthermore, two groups of fixing rods are symmetrically installed on the inner wall of the protective cover body, and the lengths of the two groups of fixing rods are greater than the width of the tempered glass, and the distance between the two groups of fixing rods is greater than the length of the tempered glass.

[0009] By adopting the above technical solution, the limit plate can move up and down stably, and the limit plate can better drive the soft rubber scraper to clean.

[0010] Furthermore, the end of the soft rubber scraper is in contact with the tempered glass, and the length of the soft rubber scraper is greater than the length of the tempered glass.

[0011] By adopting the above technical solution, the friction force of the soft rubber scraper on the tempered glass is increased when it moves downward, thereby achieving a better cleaning effect, and the soft rubber scraper can clean the tempered glass in all directions.

[0012] Furthermore, the minimum angle between the connecting plate and the limiting plate is 45 degrees, and the connecting plate is inclined in the direction of the tempered glass away from the electric telescopic rod.

[0013] By adopting the above technical solution, the soft rubber scraper can be in contact with the baffle, so that the waste on the soft rubber scraper is blocked and falls off.

[0014] Furthermore, the start button is installed at both ends of the limit plate, and the motor rotates in different directions after the start button contacts the first fixed block and after the start button contacts the second fixed block.

[0015] By adopting the above technical solution, the motor can be started better and the soft rubber scraper can be reset.

[0016] Furthermore, the waste box is slidably connected to the protective cover body, and the length of the waste box is greater than the length of the baffle, and the distance between the end of the waste box and the outer wall of the protective cover body is greater than the distance between the end of the baffle and the outer wall of the protective cover body.

[0017] By adopting the above technical solution, the waste box can be pulled out, and the collected waste can be better cleaned, so that all the collected waste can enter the waste box under the action of the soft rubber scraper and the baffle.

[0018] In summary, the present invention has the following beneficial effects:

[0019] The utility model is provided with a protective cover body, a waste box, a fixed block, a fixed rod, a baffle, a limit plate, and a soft rubber scraper. Two sets of handles are provided on the lower section of the outer wall of the protective cover body to facilitate the operator's later disassembly. An observation window composed of tempered glass is opened in the middle of the protective cover body to facilitate the operator to observe the situation inside the equipment. A fixed rod is installed on the inner wall of the protective cover body, and the limit plate is slidably installed on the fixed rod. An electric telescopic rod connected to the limit plate is fixedly installed on the inner wall of the protective cover body, so that the limit plate is fixed under the action of the electric telescopic rod and the fixed rod. The scraper moves up and down, and a motor is installed on the limit plate to control the movement of the scraper, and start buttons are provided at both ends of the limit plate. A fixed block corresponding to the start button is provided on the protective cover body, and a soft rubber scraper is installed on the limit plate, and the bottom end of the soft rubber scraper is in contact with the tempered glass. When the limit plate descends, the soft rubber scraper can scrape the waste off the tempered glass. There is also a baffle under the soft rubber scraper, and a waste box is provided under the baffle. When the soft rubber scraper falls to the lowest point and moves, it will connect with the baffle. At this time, the baffle will scrape the waste on the soft rubber scraper into the waste box.

[0031] See also Figure 2 - Figure 5The minimum angle between the connection 13 and the limiting plate 11 is 45 degrees. At this time, the friction between the soft rubber scraper 12 and the tempered glass 3 is the largest, and the connecting plate 13 is inclined in the direction of the tempered glass 3 away from the electric telescopic rod 6, so that the soft rubber scraper 12 can contact with the baffle 10, thereby blocking the waste on the soft rubber scraper 12.

[0032] See also Figure 2 - Figure 5 The start button 5 is installed at both ends of the limit plate 11, which can better start the motor 7, and the direction of rotation of the motor 7 is different after the start button 5 contacts the first fixed block 8 and after the start button 5 contacts the second fixed block 801, so that the soft rubber scraper 12 can be reset.

[0033] See also Figure 1 - Figure 5 The waste box 4 is slidably connected to the protective cover body 1, so that the waste box 4 can be pulled out to better clean the collected waste, and the length of the waste box 4 is greater than the length of the baffle 10, and the distance between the end of the waste box 4 and the outer wall of the protective cover body 1 is greater than the distance between the end of the baffle 10 and the outer wall of the protective cover body 1, so that the waste collected under the action of the soft rubber scraper 12 and the baffle 10 can all enter the waste box 4.

[0034] When the limit plate 11 is raised to the highest point, the start button will contact the first fixed block 8 above, so that the motor 7 will reset the soft rubber scraper 12, so that the tempered glass 3 can be better cleaned.
