Description

Technical Field

[0001] The utility model belongs to the technical field of flat glass processing, and in particular relates to a flatness milling tool. Background Art

[0002] After the forming process, flat glass needs to be milled on both sides to achieve the required accuracy. However, the surface of flat glass before milling is actually uneven.

[0003] In the prior art, the problem encountered when milling flat glass is that when milling the front side of the flat glass, the back side of the flat glass has not been milled yet and is actually uneven. The flat glass is placed on the milling tool, and the back side of the flat glass cannot be completely fitted with the milling tool, and there will be gaps. As a result, when milling the front side of the flat glass, there is no supporting force in the gap on the back side, and the front flat glass here will sink under the force, affecting the effect of plane milling.

[0004] Therefore, in order to make the flat glass meet the flatness requirements, it has to be milled multiple times on both sides. This operation will result in too much reserved thickness for the processing of the flat glass, waste of materials, and repeated milling of the front and back sides of the flat glass, as well as the turning, positioning and leveling operations before milling, all take a long time, reducing production efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a flatness milling tool for solving the technical problems in the prior art that milling out qualified flat glass requires multiple operation steps, resulting in low production efficiency and requiring a large processing allowance for the flat glass, thereby wasting materials.

[0006] The utility model solves the above technical problems with the following technical solutions: a flatness milling tool, comprising:

[0007] An upper bracket, wherein the upper bracket is provided with a plurality of accommodating holes;

[0008] A lower bracket, the lower bracket is arranged below the upper bracket, and the upper bracket is connected to the lower bracket through a plurality of support columns;

[0009] A plurality of macro adjustment rods are arranged in the accommodating holes one by one, and the ends of the macro adjustment rods can extend out of the top surface of the upper bracket.

[0010] The utility model is used for the first time milling and grinding of flat glass, and the flat glass is placed on the milling and grinding tooling, and the gap between the back side of the flat glass and the plane of the milling and grinding tooling is filled by adjusting the extension length of the micro-distance adjustment rod at different positions, thereby reducing the deformation of the flat glass during milling and grinding, improving the milling efficiency, and reducing the number of repeated milling. In this way, the processing allowance of the flat glass can be reduced, and the purpose of saving materials is achieved.

[0011] Furthermore: the upper support comprises an upper frame, a plurality of upper cross beams and upper longitudinal beams are arranged in the upper frame, and the upper cross beams and the upper longitudinal beams are arranged at intervals;

[0012] The lower support comprises a lower frame, a plurality of lower cross beams and lower longitudinal beams are arranged in the lower frame, and the lower cross beams and the lower longitudinal beams are arranged at intervals;

[0013] The upper frame and the lower frame have the same size, the upper frame and the lower frame are aligned, and the upper frame is connected to the lower frame via a plurality of support columns;

[0014] The upper cross beam and the lower cross beam are offset, the upper longitudinal beam and the lower longitudinal beam are offset, each of the upper cross beams is connected to a plurality of the lower longitudinal beams through a plurality of the support columns, and each of the upper longitudinal beams is connected to a plurality of the lower cross beams through a plurality of the support columns.

[0015] The beneficial effects of adopting this step are as follows: the upper frame and the lower frame are connected by support columns, and the gap in the middle is convenient for adjusting the extension length of the macro adjustment rod; secondly, the upper cross beam and upper longitudinal beam of the upper frame and the lower cross beam and lower longitudinal beam of the lower frame are staggered, so that the number of support columns is increased, the overall structural strength can be improved, it is not easy to deform, and the welds between the upper cross beam, upper longitudinal beam, support columns, lower cross beam and lower longitudinal beam can be dispersed, thereby reducing the influence of welding stress.

[0016] Furthermore: the accommodating hole is located at the intersection of each upper cross beam and each upper longitudinal beam.

[0017] The beneficial effect of adopting this step is that the structural strength at the intersection of the upper cross beam and the upper longitudinal beam is higher and the load-bearing capacity is stronger.

[0018] Further: the macro adjustment rod includes:

[0019] A fixed sleeve, one end of which is provided with a micro-pitch internal thread;

[0020] An adjusting rod and a differential cylinder, one end of the adjusting rod extends into the fixed sleeve, the rod body of the adjusting rod is provided with an external thread adapted to the macro internal thread, the other end of the adjusting rod is fixedly connected to the differential cylinder, and scales are provided on the fixed sleeve and the differential cylinder.

[0021] The beneficial effect of adopting this step is: through the macro internal thread, the micron-level displacement of the macro adjustment rod is achieved, which is more suitable for the gap range on the back of the flat glass.

[0022] Furthermore: an upper limit ring on the top surface and a lower limit ring on the bottom surface are provided in the receiving hole, and the upper limit ring and the lower limit ring are interference fit with the receiving hole;

[0023] A positioning sleeve is further provided between the upper limiting ring and the lower limiting ring, and the positioning sleeve is interference fit with the fixing sleeve;

[0024] The inner hole of the upper limit ring is over-fitted with the adjusting rod, and the lower limit ring is over-fitted with the fixing sleeve.

[0025] The beneficial effects of adopting this step are as follows: the position of the positioning sleeve is limited by the upper limit ring and the lower limit ring, and the position of the fixed sleeve is limited by the positioning sleeve; in addition, the upper limit ring can also prevent the axial bending of the macro adjustment rod.

[0026] Furthermore: the top end of the adjusting rod is a ball head.

[0027] The beneficial effect of adopting this step is that the top edge of the ball head is a point, and it is in point contact with the back of the flat glass, which has stronger adaptability.

[0028] The beneficial effects of the utility model are:

[0029] 1. The number of micro-adjustment rods in the flatness milling tool of the present application is large, the distribution range is wide, and the micro-adjustment rods are balanced. By adjusting the length of each micro-adjustment rod extending out of the upper bracket, the micro-adjustment rod can fill the gap between the back of the flat glass and the top surface of the upper bracket. The micro-adjustment rod provides support force when the flat glass is milled to avoid deformation of the gap of the flat glass, which can improve the flatness milling effect of the flat glass, thereby reducing the operation steps of turning over, positioning and leveling the flat glass, and improving production efficiency; at the same time, due to the improvement of the milling effect, the processing allowance of the flat glass can also be reduced, so as to achieve the purpose of saving materials;

[0030] 2. The macro adjustment rods in the present application are all independently arranged on the upper bracket. Any damage to the macro adjustment rod can be repaired and replaced individually, which can reduce the maintenance cost of the milling tooling. BRIEF DESCRIPTION OF THE DRAWINGS
