Abstract

The utility model provides a numerical control planer type milling machine with an anti-deviation structure. A numerical control planer type milling machine with an anti-deviation structure comprises a rack, a portal frame, a milling cutter mechanism, a workbench and the like. A portal frame is installed on the rear portion of the upper side of the rack. A milling cutter mechanism is mounted on the portal frame; a workbench is fixedly connected to the middle of the upper side of the rack. After the pressure sensing piece makes contact with the side face of the thin plate piece, the pressure sensing piece generates downward pressing force on the thin plate piece due to the fact that the pressure sensing piece is obliquely arranged, the stability of the thin plate piece is enhanced, and therefore the situation that when the thin plate piece is machined subsequently, the thin plate piece displaces due to cutting force and other factors is avoided; therefore, the processing quality of the thin plate is influenced.

Description

TECHNICAL FIELD

[0001] The utility model relates to gantry milling machine technical field, especially a numerical control gantry milling machine with anti -drifting structure. BACKGROUND

[0002] Gantry milling machine is a milling machine with portal frame and horizontal long bed. A plurality of milling cutters can be used to process the surface simultaneously on the gantry milling machine, and the machining precision and production efficiency are relatively high, which is suitable for processing the plane and inclined plane of workpieces in batch and mass production.

[0003] In the process of machining workpieces by the gantry milling machine, the workpieces need to be fixed on the machining table first, so as to ensure that the workpieces will not deviate during machining. In the existing gantry milling machine, several sets of pressing plates and screw rods are usually used to realize the clamping and fixing function. This not only is troublesome to operate, but also when clamping and fixing the thin plate, the thin plate will be elastically deformed or plastically deformed due to poor rigidity of the thin plate if the clamping force is too large, which will affect the flatness of the thin plate and the subsequent machining precision. If the clamping force is too small, the thin plate will be displaced due to cutting force and other factors, which will affect the machining quality of the thin plate.

[0004] At the same time, during the machining process of the thin plate, the cutting heat will cause the temperature of the thin plate to rise. Since the thin plate has fast heat dissipation but small heat capacity, the temperature changes sensitively, which will cause the thin plate to expand unevenly due to heat, resulting in problems such as decrease of size precision and shape deformation of the thin plate. CONTENT OF THE UTILITY MODEL

[0005] In order to overcome the shortcomings that the thin plate will be elastically deformed or plastically deformed due to poor rigidity of the thin plate if the clamping force is too large during clamping, which will affect the flatness of the thin plate and the subsequent machining precision, and the thin plate will be displaced due to cutting force and other factors if the clamping force is too small, the utility model provides a numerical control gantry milling machine with anti -drifting structure.

[0006] The technical implementation scheme of the utility model is: a numerical control planer with anti-deviation structure, comprising a frame, a portal frame, a milling cutter mechanism and a workbench; the portal frame is installed on the upper rear part of the frame; the milling cutter mechanism for processing sheet parts is installed on the portal frame; the workbench is fixedly connected to the upper middle part of the frame; further comprising a fixing seat, a supporting plate, a suction cup, an electric push rod, an L-shaped plate and a clamping plate; a plurality of fixing seats are installed on the workbench; a supporting plate for placing sheet parts is fixedly connected to all the fixing seats; a plurality of suction cups are fixedly connected to the supporting plate, and the suction cups are retractable; a plurality of electric push rods are fixedly connected to the lower side of the supporting plate; an L-shaped plate is fixedly connected to the retractable part of each electric push rod; a clamping plate is fixedly connected to each L-shaped plate; further comprising a pressure sensing sheet; a pressure sensing sheet is installed on each clamping plate, and the pressure sensing sheets are arranged obliquely.

[0007] More preferably, further comprising a cooling pipe; the cooling pipe for conveying cooling liquid is arranged in the supporting plate.

[0008] More preferably, further comprising a supporting plate and an air outlet plate; a plurality of supporting plates are fixedly connected to the left upper part of the workbench; an air outlet plate is installed on all the supporting plates.

[0009] Beneficial effects: the clamping plate and the pressure sensing sheet will position and clamp the sheet part, thereby facilitating subsequent processing of the sheet part.

[0010] After the pressure sensing sheet contacts the side surface of the sheet part, the pressure sensing sheet will press the sheet part downward due to the oblique arrangement of the pressure sensing sheet, thereby enhancing the stability of the sheet part, so that displacement of the sheet part due to cutting force and other factors during subsequent processing of the sheet part is avoided, thereby affecting the processing quality of the sheet part.

[0011] Meanwhile, the clamping force of the clamping plate and the pressure sensing sheet on the sheet part is kept within the set range through the cooperation of the pressure sensing sheet, thereby avoiding elastic deformation or even plastic deformation of the sheet part due to excessive clamping force during clamping, which will affect the flatness of the sheet part and subsequent processing accuracy, and then the suction cup is controlled to adsorb the lower surface of the sheet part, thereby further enhancing the stability of the sheet part.

[0012] The air is conveyed to the air outlet plate by the external pump, and then the air is blown out through the air outlets on the air outlet plate, and the blown-out gas will blow off the debris on the surface of the sheet part, thereby avoiding that too much debris will affect the quality of the surface processing of the sheet part.

[0013] Meanwhile, the blown gas will also have a heat dissipation effect on the sheet part during processing. At the same time, since the supporting plate is made of a material with good heat conduction performance, the heat on the sheet part will be conducted to the supporting plate, so that the heat dissipation effect of the sheet part is further enhanced, thereby avoiding the problem that the cutting heat will cause the temperature of the sheet part to rise during the processing of the sheet part, and since the sheet part has fast heat dissipation but small heat capacity and is sensitive to temperature change, the sheet part will produce uneven thermal expansion, resulting in problems such as decrease in size precision and shape deformation of the sheet part.

[0021] Example 1

[0022] A numerical control planer type milling machine with anti-deviation structure, such as Figures 1-5As shown, including organic frame 1, gantry 2, milling cutter mechanism 3 and workbench 4; frame 1 upper rear portion mounted with gantry 2; gantry 2 is installed with milling cutter mechanism 3; frame 1 upper middle fixedly connected with workbench 4;

[0023] Also including fixed seat 5, supporting plate 6, suction cup 7, electric push rod 8, L-shaped plate 9 and clamping plate 10; four matrix distribution fixed seat 5 is installed on the workbench 4; all of the fixed seat 5 is fixedly connected with supporting plate 6; supporting plate 6 is fixedly connected with four matrix distribution suction cup 7, and the suction head of suction cup 7 can be telescopic; the lower side of supporting plate 6 is bolted with four matrix distribution electric push rod 8; each electric push rod 8 is fixedly connected with an L-shaped plate 9; each L-shaped plate 9 is fixedly connected with a clamping plate 10.

[0024] Supporting plate 6 is set to be made of material with good heat conduction performance, so that the heat on the sheet part can be better conducted to the supporting plate 6 when the sheet part is processed, so as to avoid the temperature of the sheet part being too high during processing, which causes the sheet part to produce uneven thermal expansion.

[0025] Also including pressure sensitive sheet 11; each clamping plate 10 is provided with a pressure sensitive sheet 11, and the pressure sensitive sheet 11 is inclined.

[0026] Also including cooling pipe 12; the cooling pipe 12 is arranged in the supporting plate 6.

[0027] Also including support plate 21 and air outlet plate 22; two front and rear symmetrical distribution of support plate 21 is fixedly connected on the upper left side of workbench 4; all of the support plate 21 is installed with air outlet plate 22.

[0028] When the numerical control planer milling machine with the anti-deviation structure is used, first, the cooling pipe 12 is connected with the external cooler, and the air outlet plate 22 is connected with the external pump. Then, the staff places the sheet metal to be processed on the supporting plate 6. It should be noted that in the initial state, the upper end of the supporting plate 6 is not placed with the sheet metal, and the suction head of the suction cup 7 protrudes from the upper end of the supporting plate 6, so that the suction head of the suction cup 7 can subsequently adsorb the sheet metal. When the sheet metal is placed on the supporting plate 6, the suction head of the suction cup 7 will adsorb the sheet metal, and the suction head of the suction cup 7 will shrink downward under the action of the gravity of the sheet metal, so that the sheet metal is in contact with the surface of the supporting plate 6, which is helpful for the direct heat transfer between the sheet metal and the supporting plate 6 (the specific structure of the suction cup 7 used in this embodiment is known to those skilled in the art, so the description is not more detailed, but it does not affect the understanding of those skilled in the art). Then, the electric push rod 8 is controlled to move the four L-shaped plates 9 to the middle of the supporting plate 6, and the clamping plate 10 and the pressure sensing sheet 11 move synchronously with the L-shaped plate 9. It should be noted that when the sheet metal is placed on the supporting plate 6 and is not centered, that is, the sheet metal deviates to the left, the left clamping plate 10 and the pressure sensing sheet 11 will push the sheet metal to the right, and when the sheet metal deviates to the right, the right clamping plate 10 and the pressure sensing sheet 11 will push the sheet metal to the left, and when the sheet metal deviates forward or backward, the front clamping plate 10 and the pressure sensing sheet 11 will push the sheet metal to move backward or forward. In this way, the clamping plate 10 and the pressure sensing sheet 11 will play a role of positioning and clamping the sheet metal, thereby facilitating the subsequent processing of the sheet metal.

[0029] At the same time, after the pressure sensing sheet 11 contacts the side surface of the sheet metal, the pressure sensing sheet 11 will generate a downward pressing force on the sheet metal due to the inclined arrangement of the pressure sensing sheet 11, so as to enhance the stability of the sheet metal, thereby avoiding displacement of the sheet metal due to cutting force and other factors during subsequent processing of the sheet metal, and thus affecting the processing quality of the sheet metal. At the same time, through the cooperation of the pressure sensing sheet 11, the clamping force of the clamping plate 10 and the pressure sensing sheet 11 on the sheet metal is kept within the set range, thereby avoiding the elastic deformation or plastic deformation of the sheet metal due to the poor rigidity of the sheet metal when clamping, which will affect the flatness of the sheet metal and the subsequent processing precision. Then, the suction cup 7 is controlled to adsorb the lower surface of the sheet metal, thereby further enhancing the stability of the sheet metal.

[0030] When the sheet piece is fixed, the worker can control the milling cutter mechanism 3 to process the sheet piece, in this process, the external pump is controlled to send air to the air outlet plate 22, then the air is blown out through the air outlet of the air outlet plate 22, and the blown-out gas can blow off the debris on the surface of the sheet piece, so as to avoid that too much debris will affect the quality of the sheet piece surface processing, at the same time, the blown-out gas will also play a heat dissipation effect on the sheet piece during processing, at the same time, since the supporting plate 6 is made of material with good heat conduction performance, the heat on the sheet piece will be conducted to the supporting plate 6, so that the heat dissipation effect of the sheet piece is further enhanced, so as to avoid that the cutting heat will make the temperature of the sheet piece rise during the processing of the sheet piece, and since the sheet piece has small heat capacity and fast heat dissipation, the temperature changes sensitively, so that the sheet piece will produce uneven thermal expansion, which will cause the problems of size precision reduction and shape deformation of the sheet piece, at the same time, the external cooler is controlled to send the cooling liquid to the cooling pipe 12, and the heat in the supporting plate 6 is taken away by the cooling liquid, so that the supporting plate 6 can continuously conduct heat to the sheet piece.

[0031] While the application has been described with reference to example embodiments, it will be understood by those skilled in the art that various changes can be made and equivalents can be substituted for elements thereof without departing from the scope of the present application. In addition, many modifications can be made to adapt a particular situation or material to the teachings of the application without departing from the central inventive concept described herein.
