Description

Technical Field

[0001] The utility model relates to the technical field of machine tools for milling the surface of aluminum alloy ingots, in particular to a double-end face milling machine capable of online measuring the milling depth of aluminum ingots. Background Art

[0002] Before rolling, aluminum alloy ingots need to be milled to remove the oxide layer on their surface. The existing milling method is fixed value elimination, that is, the milling depth of each aluminum ingot is fixed during the milling process. However, due to the uneven surface of the incoming aluminum ingots, some aluminum ingots will have insufficient milling depth after milling, and the oxide layer will not be completely removed. Therefore, secondary milling is necessary, resulting in a waste of working hours. If the milling depth of the aluminum ingots is uniformly increased to improve the above problems, it will cause excessive milling of some aluminum ingots, resulting in material waste, which in turn affects the economic benefits of the enterprise. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the utility model discloses a double-end milling machine with the function of online measuring the milling depth of aluminum ingots. Before milling, laser scanning and ranging are performed on the surfaces to be processed on both sides of the aluminum ingot, and the milling depths of the surfaces to be processed on both sides of the aluminum ingot are calculated. While ensuring that the oxide layer is completely removed in one milling process, the amount of aluminum ingot removed by milling is minimized, thereby ensuring the economic benefits of the enterprise.

[0004] In order to achieve the purpose of the utility model, the utility model adopts the following technical scheme: a double-end milling machine with online measurement of the milling depth of aluminum ingots, comprising an end milling machine and an ingot mounting seat, wherein the end milling machine is fixedly arranged on both sides of the ingot mounting seat in a parallel and symmetrical manner; the end milling machine comprises a bed assembly and a milling head assembly, and the milling head assembly is horizontally movable and arranged on the upper part of the bed assembly; the double-end milling machine also includes a control system and a laser rangefinder, wherein the laser rangefinder is fixedly arranged on the milling head assembly, with the light-emitting side facing the ingot mounting seat, and the control system and the laser rangefinder are electrically connected; before the aluminum ingot is milled, the milling head assembly is retracted to an initial position in the milling depth direction, and the milling head assembly drives the laser rangefinder to scan along the bed assembly once, and the scanning data is transmitted to the control system for processing, so as to obtain the unevenness of the two sides of the aluminum ingot to be milled; the control system controls the feed amount of the milling head assembly on the corresponding side in the milling depth direction according to the measured unevenness, thereby obtaining the milling depth of the surfaces to be processed on both sides of the aluminum ingot.

[0005] Furthermore, the bed assembly includes a bed, a transverse drive motor, a transverse screw, and a transverse nut. The transverse drive motor is fixedly arranged at one end of the bed, the transverse screw is rotatably arranged between the two side end surfaces, the transverse drive motor is transmission-connected to the transverse screw, and the transverse nut is movably arranged on the transverse screw.

[0006] Furthermore, the milling head assembly includes a transverse pallet, a longitudinal guide rail seat, a longitudinal pallet, and a milling head gearbox. The transverse pallet, the longitudinal guide rail seat, the longitudinal pallet, and the milling head gearbox are arranged in sequence from bottom to top. The transverse pallet is fixedly connected to the longitudinal guide rail seat, the longitudinal guide rail seat is slidingly connected to the longitudinal pallet, and the longitudinal pallet is fixedly connected to the milling head gearbox; the milling head assembly is slidingly connected to the bed assembly through the transverse pallet.

[0007] Furthermore, the transverse nut is fixedly arranged at the lower part of the transverse tray.

[0008] Furthermore, a longitudinal drive motor is fixedly arranged at one end of the longitudinal guide rail seat, a longitudinal lead screw is rotatably arranged between the two side end surfaces, and the longitudinal drive motor and the longitudinal lead screw are transmission-connected; a longitudinal nut is movably arranged on the longitudinal lead screw; and the longitudinal nut is fixedly arranged at the lower part of the longitudinal tray.

[0009] Furthermore, the transverse drive motor or the longitudinal drive motor is a servo motor; the transverse drive motor and the longitudinal drive motor are electrically connected to the control system; when the transverse drive motor and the longitudinal drive motor are both servo motors, during the milling process of both sides, the control system compensates for the feed amount of the milling head assembly in the milling depth direction, thereby also solving the problem of large milling amount of the aluminum ingot due to the skewed positioning of the aluminum ingot during the clamping.

[0010] Due to the adoption of the technical solution as described above, the utility model has the following beneficial effects: the utility model discloses a double-end face milling machine with the function of online measuring the milling depth of aluminum ingots, comprising an end face milling machine and an ingot mounting seat, wherein the end face milling machine is fixedly arranged on both sides of the ingot mounting seat in a parallel and symmetrical manner; the end face milling machine comprises a bed assembly and a milling head assembly, wherein the milling head assembly is horizontally movable and arranged on the upper part of the bed assembly; the double-end face milling machine also comprises a control system and a laser rangefinder, wherein the laser rangefinder is fixedly arranged on the milling head assembly, wherein the light emitting side faces the ingot mounting seat, and the control system and the laser rangefinder are electrically connected Before the aluminum ingot is milled, the milling head assembly retreats to the initial position in the direction of the milling depth, and the milling head assembly drives the laser rangefinder to scan along the bed assembly once, and the scanning data is transmitted to the control system for processing, so as to obtain the unevenness of the two sides of the aluminum ingot to be milled; the control system controls the feed amount of the milling head assembly on the corresponding side at the milling depth according to the measured unevenness, so as to obtain the milling depth of the surfaces to be processed on both sides of the aluminum ingot, while ensuring that the oxide layer is completely removed in one milling process, it also ensures that the amount of aluminum ingot milling is minimized, thereby ensuring the economic benefits of the enterprise.

[0024] A longitudinal drive motor 1.2.7 is fixedly arranged at the front end of the longitudinal guide rail seat 1.2.2, and a longitudinal lead screw 1.2.8 is rotatably arranged between the front and rear end faces through a bearing, and the longitudinal drive motor 1.2.7 and the longitudinal lead screw 1.2.8 are connected by a coupling transmission; a longitudinal nut 1.2.9 is movably arranged on the longitudinal lead screw 1.2.8, and the longitudinal nut 1.2.9 is fixedly arranged at the lower part of the longitudinal tray 1.2.3; when the longitudinal drive motor 1.2.7 drives the longitudinal lead screw 1.2.8 to rotate, the longitudinal nut 1.2.9 moves horizontally and longitudinally along the axis of the longitudinal lead screw 1.2.8, driving the milling head gearbox 1.2.4 to move horizontally and longitudinally as a whole, and the movement amount in this direction actually controls the milling depth of the aluminum ingot processing surface;

[0025] The double-end milling machine also includes a control system and a laser rangefinder 3. The laser rangefinder 3 is fixedly arranged on the side of the adjacent end milling cutter disc 1.2.5 on the milling head gearbox 1.2.4 through a bracket. The light output direction of the laser rangefinder 3 is toward the ingot mounting holder 2. The control system is electrically connected to the laser rangefinder 3; the longitudinal drive motor 1.2.7 is a servo motor, and the longitudinal drive motor 1.2.7 is electrically connected to the control system.

[0026] See the instruction manual Figure 1 : When it is necessary to perform milling on the two opposite sides of the aluminum ingot, first return the milling head assembly 1.2 to the original position; the aluminum ingot 4 is hung on the ingot clamping seat 2 by the overhead crane, and after the operator completes the positioning of the aluminum ingot 4, it is locked by the aluminum ingot clamping device; calibrate the laser rangefinder 3 to ensure that its actual output distance measurement value is the distance from the end milling cutter disc 1.2.5 to the aluminum ingot 4;

[0027] The two transverse drive motors 1.1.2 are started synchronously, so that the two milling head assemblies 1.2 move synchronously along the transverse guide rails of the bed 1.1.1. At the same time, the laser rangefinder 3 performs horizontal scanning and distance measurement on the front and rear sides of the aluminum ingot 4. The scanning and distance measurement data is transmitted to the control system. After processing, the unevenness curve of the front and rear sides of the aluminum ingot 4 in a certain horizontal section is obtained. See the attached manual for details. Figure 6 ; The control system fits the roughness curve into a straight line, and then offsets the fitted straight line to the inside of the aluminum ingot 4 until the fitted straight line is completely separated from the roughness curve. At this time, the position of the fitted straight line is the milling surface of the aluminum ingot 4. The distance S between the end milling cutter disc 1.2.5 and the milling surface when it is in the original position is the horizontal and longitudinal feed amount of the corresponding end milling cutter disc 1.2.5 during milling, thereby obtaining the optimal milling depth;

[0028] The control system accurately controls the rotation of the longitudinal drive motor 1.2.7 to drive the two milling head assemblies 1.2 to move to the optimal milling depth position, and then synchronously starts the two transverse drive motors 1.1.2 to make the two milling head assemblies 1.2 move synchronously along the transverse guide rails of the bed 1.1.1 to remove the oxide layer on the surface of the aluminum ingot. Embodiment 2:

[0029] The transverse drive motor 1.1.2 and the longitudinal drive motor 1.2.7 are both servo motors; the transverse drive motor 1.1.2 and the longitudinal drive motor 1.2.7 are electrically connected to the control system; during the milling process of the two sides of the aluminum ingot, the control system can compensate for the feed amount of the milling head assembly in the milling depth direction, so it can also solve the problem of excessive milling amount of the aluminum ingot due to the non-parallelism of the milling surface and the guide surface of the bed 1.1.1 guide rail when the aluminum ingot is installed and positioned skewed;

[0030] See the instruction manual Figure 7 : If there is a positioning deviation problem when the aluminum ingot 4 is locked on the ingot clamping seat 2, if it is still processed in the manner of Example 1, there will inevitably be a problem of excessive processing volume. At this time, the control system can simultaneously compensate for the feed amount of the milling head assembly in the milling depth direction, so that the tool path coincides with the milling processing surface, thereby solving the problem of excessive milling processing volume when the aluminum ingot is mounted with a positioning deviation.

[0031] The parts not described in detail in this utility model are prior art.
