Description

Technical Field

[0001] The utility model relates to the field of milling machine bases, and more specifically to a base self-cleaning light gantry milling machine. Background Art

[0002] In the field of mechanical processing, gantry milling machines are commonly used equipment, especially light gantry milling machines, which have been widely used in the precision processing industry due to their compact structure and convenient operation. However, during actual processing, a large amount of cutting iron chips will accumulate on the base. If these cutting iron chips are not cleaned in time, it may not only affect the processing accuracy of the workpiece, but also make it inconvenient to disassemble and assemble the subsequent workpiece fixture.

[0003] Although there are gantry milling machines with cleaning mechanisms installed on the base to clean the cutting iron chips, they are usually configured as a scraper or push block structure that matches the cross-sectional structure of the fixture slot, relying on the telescopic rod of the cylinder to push the scraper or push block to move back and forth to clean the cutting iron chips inside the fixture slot, or relying on the rotation of the threaded shaft to drive the scraper or push block to move back and forth to clean the cutting iron chips inside the fixture slot. Although the setting of this cleaning mechanism can clean the cutting iron chips inside the fixture slot, regardless of whether it is driven by the telescopic rod of the cylinder or the rotation of the threaded shaft, the telescopic rod and threaded shaft of the cylinder need to be set in the fixture slot, which will undoubtedly further occupy the space inside the fixture slot, which is not conducive to the smooth insertion of the fixture used to clamp the workpiece into the fixture slot, and the continuity of the cleaning process is poor. Therefore, we propose a base self-cleaning light gantry milling machine to solve the above-mentioned problems. Utility Model Content

[0030] Example: See Figure 1-Figure 10 A base self-cleaning light gantry milling machine, comprising a milling machine body 1, a base 2 suitable for mounting a workpiece to be processed is fixedly installed on the milling machine body 1 by bolts, a plurality of fixture slots 201 with a T-shaped cross section are equidistantly provided on the base 2, an avoidance through-groove 202 is also provided on the base 2 at the bottom position of the fixture slot 201, edge guide strips 2011 with a triangular cross section are symmetrically fixedly connected on both sides of the inner wall of the fixture slot 201, and a metal debris conveying mechanism 3 is provided between the fixture slot 201 and the avoidance through-groove 202;

[0031] The metal scrap conveying mechanism 3 includes a U-shaped connecting plate 4 arranged inside the clamping slot 201, a group of ear pieces 401 are fixedly welded at both ends of the U-shaped connecting plate 4, and the ear pieces 401 are fixedly installed at corresponding positions on the base 2 by bolts, and U-shaped roller brackets 1 5 and U-shaped roller brackets 2 6 are respectively arranged at both ends of the U-shaped connecting plate 4, one side of the U-shaped roller bracket 1 5 is fixedly installed at one end of the U-shaped connecting plate 4 by bolts, and a group of connecting bolts 7 are fixedly welded on one side of the U-shaped roller bracket 2 6, and a group of jacks are opened at the other end of the U-shaped connecting plate 4 corresponding to the position of the group of connecting bolts 7, and the group of connecting bolts 7 are plugged into the inside of the group of jacks, and the end of the group of connecting bolts 7 is threadedly connected with an adjusting nut 701, and a group of connecting bolts 7 located between the U-shaped roller bracket 2 6 and the other end of the U-shaped connecting plate 4 are sleeved with a supporting spring 8;

[0032] The U-shaped roller bracket 15 and the U-shaped roller bracket 26 are respectively fixedly mounted with a pulley 10 and a pulley 2 12 through a rotating shaft 19 and a rotating shaft 2 11. The connection between the rotating shaft 19 and the U-shaped roller bracket 15 is rotatably connected through a bearing, and both ends of the rotating shaft 19 extend to the outside of the U-shaped roller bracket 15. The connection between the rotating shaft 2 11 and the U-shaped roller bracket 26 is rotatably connected through a bearing, and the pulley 10 and the pulley 2 12 are connected through a conveyor belt 13;

[0033] A micro motor 14 is fixedly mounted on the base 2 located on one side of the pulley 10, and the ends of two adjacent rotating shafts 9 are connected via a coupling 15, and the end of the driving shaft on one side of the micro motor 14 is connected to the corresponding end of the rotating shaft 9 via a coupling 2 16.

[0034] The working principle of this base self-cleaning light gantry milling machine is:

[0035] First, place the workpiece to be processed on the base 2, then select a number of suitable and adjustable C-type clamps and place them on the periphery of the workpiece to be processed, and make the bottom of the C-type clamp clamped on the base 2 through the corresponding clamp clamp slot 201, and the top of the C-type clamp overlaps the corresponding position of the top of the workpiece to be processed, and tighten the fastening screws of the C-type clamp (the specific structure and corresponding use method of the C-type clamp are known in the existing public technology, so they will not be described in detail here), then the milling machine body 1 can be started to process the workpiece to be processed, and the micro motor 14 can be started at the same time for later chip removal;

[0036] During the processing, if the cutting iron chips fall into the inside of the fixture slot 201, the cutting iron chips will smoothly fall onto the conveyor belt 13 of the metal chip conveying mechanism 3 through the guiding effect of the two edge guide strips 2011 inside the fixture slot 201. At this time, the started micro motor 14 drives the corresponding position of the rotating shaft 9 to rotate through the coupling 16. Then, since the ends of two adjacent rotating shafts 9 are connected through the coupling 15, the micro motor 14 can drive several metal chip conveying mechanisms 3 at the same time. The rotating shaft 19 rotates, thereby driving the pulleys 10 of several metal chip conveying mechanisms 3 to rotate. Then, since the pulley 10 is connected to the corresponding pulley 2 12 through the conveyor belt 13, the micro motor 14 can simultaneously drive several conveyor belts 13 to rotate, and the cutting iron chips that fall into the inside of the fixture slot 201 and on the conveyor belt 13 are continuously transported outward, so as to achieve the effect of cleaning and removing chips, avoid the cutting iron chips filling or clogging the inside of the fixture slot 201, and avoid inconvenience in the later disassembly and assembly of the C-type fixture.

[0037] The edge guide strips 2011 with a triangular cross-section are symmetrically fixedly connected to both sides of the inner wall of the clamp slot 201. The structural design of the edge guide strips 2011 not only facilitates the smooth falling of the cut iron chips onto the conveyor belt 13, and prevents the cut iron chips from falling along the gap between the edge of the conveyor belt 13 and the side wall of the clamp slot 201 to the bottom of the inner wall of the clamp slot 201, but also can constrain and limit the rotation of the conveyor belt 13, thereby improving the stability of the conveyor belt 13 during rotation and reducing the probability of the conveyor belt 13 running off.

[0038] The avoidance through-groove 202 is provided to avoid the connection of the conveyor belt 13 and prevent interference with the connection and rotation of the conveyor belt 13;

[0039] One side of the U-shaped roller bracket 2 6 is installed in a group of jacks on the other end of the U-shaped connecting plate 4 through a group of connecting bolts 7, a group of adjusting nuts 701 and a group of supporting springs 8. The belt pulley 2 12 can be installed on the other end of the U-shaped connecting plate 4 in a floating manner, so that the adjusting nut 701 can be adjusted to control the extension and retraction of the connecting bolts 7, thereby controlling the distance between the belt pulley 10 and the belt pulley 2 12, so as to tighten the conveyor belt 13;

[0040] The distance between pulley 1 10 and pulley 2 12 is greater than the length of the base 2 in order to make the conveying distance longer and better output the cutting iron chips inside the clamp slot 201. The outer wall diameters of pulley 10 and pulley 2 12 are equal, and the outer wall diameter of pulley 10 is greater than the distance between the bottom surface of the clamp slot 201 and the top surface of the avoidance groove 202, which can prevent interference during the installation and operation of the conveyor belt 13.

[0041] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
