Description

Technical Field

[0001] The utility model relates to the field of protective doors, in particular to a protective door for a numerical control machining center. Background Art

[0002] CNC machining centers are developed from CNC milling machines. The biggest difference between CNC machining centers and CNC milling machines is that machining centers have the ability to automatically exchange machining tools. By installing tools of different uses on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changer in one clamping, realizing multiple machining functions.

[0003] In order to prevent the waste chips or water from splashing during the machining process of the workpiece, the CNC machining center will be equipped with a protective door;

[0004] However, in order to facilitate personnel to observe the processing of workpieces inside the CNC machining center, transparent glass is installed on the protective door of the existing CNC machining center;

[0005] However, since the processing water and waste chips will splash during the processing of the CNC machining center, the transparent glass is easily adhered to the processing water and waste chips, which affects the staff's observation of the workpiece inside the CNC machining center.

[0006] In addition, affected by the internal temperature of the CNC machining center and the external ambient temperature, the transparent glass is also very easy to fog, which also affects the personnel's observation of the workpiece inside the CNC machining center.

[0007] In order to solve the above problems, we propose a protective door for a CNC machining center. Utility Model Content

[0008] The utility model aims to provide a protective door for a numerical control machining center, which has the advantages of being able to scrape off machining water and machining waste chips and being able to defog the inner side of a transparent glass.

[0009] The above technical purpose of the utility model is achieved through the following technical solutions: a protective door of a CNC machining center, comprising a door body, a transparent glass is fixedly sleeved inside the door body, a heating chamber is fixedly connected to the inner side of the door body, a connecting box is fixedly connected to the bottom of the heating chamber, a driving motor is installed at the bottom of the inner cavity of the connecting box, an adjusting screw is installed at the output end of the driving motor through a coupling, a connecting plate is threadedly connected to the surface of the adjusting screw, and a rubber scraper in contact with the inner side of the transparent glass is fixedly connected to one side of the connecting plate; a fan is installed on the outer side of the door body, a connecting pipe is connected to the air outlet end of the fan, one end of the connecting pipe is connected to the connecting box, a heating pipe is installed inside the heating chamber, and a blowing pipe connected to the heating chamber is fixedly sleeved inside the door body.

[0010] By adopting the above technical scheme, by arranging a driving motor, an adjusting screw, a connecting plate, and a rubber scraper on the inner side of the transparent glass, the processing water and processing waste adhered to the inner side of the transparent glass can be scraped off from top to bottom; by arranging a fan, a connecting pipe, a heating pipe, a heating chamber, and a blowing pipe on the inner side of the transparent glass, after the processing water and processing waste are scraped off with the rubber scraper, the inner side of the transparent glass can be defogged or the transparent glass can be directly defogged after it is fogged.

[0011] The utility model is further configured as follows: two sliding grooves are arranged on the inner side of the door body, and sliding blocks fixedly connected to the connecting plate are slidably connected inside the two sliding grooves.

[0012] The above technical solution is adopted to provide a linear guide for the connecting plate through the setting of the slide groove and the slider, and to limit the position of the connecting plate to prevent the connecting plate from rotating with the adjusting screw.

[0013] The utility model is further configured such that: both sides of the connecting plate are not in contact with the door body.

[0014] By adopting the above technical solution, the two sides of the connecting plate do not contact the door body, thereby preventing the connecting plate from rubbing against the door body when sliding up and down.

[0015] The utility model is further configured as follows: a support plate is fixedly connected to the inner side of the door body, and the interior of the support plate is rotatably connected to the adjusting screw rod through a bearing.

[0016] The above technical solution is adopted to support the bottom of the adjusting screw rod by setting the supporting plate, and to restrict the adjusting screw rod from rotating at a fixed position.

[0017] The utility model is further configured as follows: the blowing pipe is specifically a square pipe, and the shape of the blowing pipe is L-shaped.

[0018] The above technical solution is adopted to blow the wind inside the heating chamber to the inner side of the transparent glass through the setting of the blowing pipe.

[0019] The utility model is further configured as follows: a heat dissipation hole is opened at the bottom of the connection box, and the number of the heat dissipation holes is at least three.

[0020] The above technical solution is adopted to dissipate the heat generated by the driving motor inside the connection box during operation by setting the heat dissipation holes.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. The utility model arranges a rubber scraper and a connecting plate on the inner side of the transparent glass, arranges a driving motor to drive the adjusting screw to rotate clockwise and counterclockwise, and uses the adjusting screw to drive the connecting plate to drive the rubber scraper to scrape up and down on the inner side of the transparent glass, so as to scrape off the processing water and processing waste chips adhered to the inner side of the transparent glass, thereby preventing the processing water and processing waste chips from adhering to the transparent glass and affecting the processing personnel's observation of the workpiece processed in the CNC machining center;

[0023] 2. The utility model generates heat by arranging a heating tube, and blows wind into the connecting tube through a blower. The wind enters the heating chamber and combines with the heat of the heating tube to generate hot air. The hot air is blown to the inside of the transparent glass through the blowing tube. The hot air can be used to dry and defog the transparent glass. At the same time, the rubber scraper can also scrape off the processing water and processing waste on the transparent glass to dry and defog it. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Furthermore, two sliding grooves 13 are provided on the inner side of the door body 1, and sliders 14 fixedly connected to the connecting plate 7 are slidably connected to the inside of the two sliding grooves 13. Through the setting of the sliding grooves 13 and the sliders 14, the connecting plate 7 is linearly guided and the position of the connecting plate 7 is limited to prevent the connecting plate 7 from rotating with the adjusting screw 6.

[0034] Furthermore, both sides of the connecting plate 7 are not in contact with the door body 1. By not having both sides of the connecting plate 7 in contact with the door body 1, it is possible to avoid friction between the connecting plate 7 and the door body 1 when sliding up and down.

[0035] Furthermore, a support plate 15 is fixedly connected to the inner side of the door body 1, and the interior of the support plate 15 is rotatably connected to the adjusting screw 6 via a bearing. The setting of the support plate 15 is used to support the bottom of the adjusting screw 6 and limit the rotation of the adjusting screw 6 in a fixed position.

[0036] Furthermore, a heat dissipation hole 16 is provided at the bottom of the connection box 4, and the number of the heat dissipation holes 16 is at least three. The heat dissipation holes 16 are provided to dissipate the heat generated by the driving motor 5 inside the connection box 4 during operation.

[0037] Brief description of the use process: When the CNC machining center is used to process the workpiece, the processing water and processing waste generated by the processing will splash on the inner side of the transparent glass 2. At this time, the drive motor 5 is started to drive the adjusting screw 6 to rotate clockwise or counterclockwise. When the adjusting screw 6 rotates clockwise, the adjusting screw 6 will drive the connecting plate 7 to drive the rubber scraper 8 to move downward.

[0040] Furthermore, the blowing pipe 12 is specifically a square tube, and the shape of the blowing pipe 12 is L-shaped. Through the setting of the blowing pipe 12, the wind inside the heating chamber 3 is blown out to the inner side of the transparent glass 2.

[0041] Brief description of the use process: When the temperature inside the CNC machining center differs too much from the external environment and fog is generated on the inside of the transparent glass 2, the rubber scraper 8 can be used to scrape it back and forth. After scraping, the fan 9 and the heating tube 11 are started, and the heating tube 11 is started to generate heat energy. The wind energy generated by the fan 9 enters the connecting tube 10 and then enters the heating chamber 3 to combine with the heat to form hot air. The hot air is blown out to the inside of the transparent glass 2 through the blowing tube 12 to dry the fog on the inside of the transparent glass 2, thereby ensuring the transparency of the transparent glass 2 and preventing water mist from affecting the vision of the processing personnel.
