Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a fast-clamping multi-purpose cutter disc. Background Art

[0002] The machinery industry cannot do without milling, and milling cannot do without fixtures. Well-designed fixtures can not only ensure the machining accuracy of parts, but also improve work efficiency. For a long time, it has been very difficult to use ordinary milling machines without CNC systems to process workpiece round table structures. The current technology is to use a chuck with a dividing head and manually control the rotation of the chuck to achieve the effect of machining the workpiece round table.

[0003] Because ordinary milling machines can only clamp one tool at a time, the tool needs to be replaced and the machine needs to be adjusted every time a different size of outer circle is processed. Frequent replacement of fixtures will not only affect the accuracy of the fixtures and equipment, but also reduce processing efficiency. At the same time, it is limited by the machine tool stroke. When the processing outer diameter is larger than the machine tool stroke, it will make processing impossible. Utility Model Content

[0028] Reference Figure 1-2 , a quick-clamping multi-purpose tool disc, is used for clamping tools in mechanical processing. It is convenient for quick installation and disassembly of tools and for processing workpieces with large outer diameters.

[0029] The quick-clamping multi-purpose tool disc comprises a tapered handle 1, a mounting disc 4, a tool handle 6 and a counterweight rod 7;

[0030] The upper end of the cone handle 1 is connected to the machine tool, and the machine tool can drive the quick clamping multi-purpose tool disc to move to process the workpiece 8. The lower end of the cone handle 1 is provided with a convex block, and the middle of the mounting plate 4 is provided with a stop 401 and a through hole 402. The tolerance is H6. The stop 401 and the through hole 402 are combined in a stepped shape. The lower end of the cone handle 1 is adapted to the stop 401. When the cone handle 1 is fixedly connected to the mounting plate 4, the lower end of the cone handle 1 can be embedded in the stop 401. At this time, the convex block is inserted into the through hole 402. In addition, since a threaded hole is provided at the bottom of the protrusion, a mounting screw 2 is provided in the threaded hole, and the mounting screw 2 is a standard 12.9-grade hexagon socket screw. The mounting screw 2 passes through the mounting disk 4, and the mounting disk 4 can be fixed to the tapered handle 1 by screwing the mounting screw 2. In addition, a washer 3 is provided on the outside of the mounting screw 2, and the washer 3 is located below the mounting disk 4, and the outer diameter of the washer 3 is larger than the through-opening 402. The washer can support the mounting disk 4, thereby firmly fixing the mounting disk 4 on the tapered handle 1.

[0031] The mounting plate 4 is disc-shaped, and a plurality of fixing hole groups are arranged on the lower end surface of the mounting plate 4, each fixing hole group includes a first fixing hole 403 and a second fixing hole 404, and a plurality of threaded holes are arranged on the mounting plate 4, each threaded hole is connected with each first fixing hole 403 and each second fixing hole 404 respectively, and a fixing screw 5 is arranged in each threaded hole, and the fixing screw 5 is a standard 12.9 grade hexagon socket screw, and a flat surface is arranged on one side of the upper end of the handle 6 and the counterweight rod 7, and the upper end of the handle 6 can be inserted into the second fixing hole 404 of a group of fixing holes, and the handle 6 can be rotated at this time. The fixing screw 5 outside the second fixing hole 404 can make one end of the fixing screw 5 press against the side plane of the tool handle 6, so that the upper end of the tool handle 6 is fixed inside the second fixing hole 404, and the upper end of the counterweight rod 7 can be inserted into the first fixing hole 403 of the same group of fixing holes. At this time, by rotating the fixing screw 5 outside the first fixing hole 403, one end of the fixing screw 5 can press against the side plane of the counterweight rod 7, so that the upper end of the counterweight rod 7 is fixed inside the first fixing hole 403, thereby completing the fixed installation of the tool handle 6 and the counterweight rod 7.

[0032] Since the first fixing hole 403 and the second fixing hole 404 in each group of fixing holes are located on a circle of the same diameter and are symmetrically distributed relative to the center of the circle, the tool handle 6 and the counterweight rod 7 can be symmetrically distributed about the center point of the mounting disk 4 after being fixed and installed, and the tool handle 6 and the counterweight rod 7 have the same outer dimensions and materials, which facilitates the rotational stability of the lifting device during rotation processing of the mounting disk 4, and facilitates stable processing of large-sized workpieces 8. Moreover, since each fixing hole group is located on a circle of different diameters, the tool handle 6 and the counterweight rod 7 can be replaced to different fixing hole groups, and multiple fixing hole groups can be designed on the mounting disk 4 to cope with a variety of processing contents, thereby facilitating the processing of workpieces 8 of different sizes.

[0033] A tool 601 is provided on the side of the lower end of the tool handle 6 close to the counterweight rod 7 to process the workpiece 8 between the tool handle 6 and the counterweight rod 7, and a flat position 701 is provided on the side of the lower end of the counterweight rod 7 close to the workpiece 8. The flat position 701 can keep a distance between the counterweight rod 7 and the workpiece 8 to avoid collision between the counterweight rod 7 and the workpiece 8 during processing.

[0034] Working principle of the quick-clamping multi-purpose cutter head:

[0035] First, install the cone handle 1 on the machine tool, then make the lower end of the cone handle 1 be embedded in the stop 401 of the mounting plate 4, at this time, the protrusion is inserted into the through hole 402, and the mounting screw 2 is screwed into the threaded hole of the cone handle 1. Since the washer 3 is provided outside the mounting screw 2, the washer can support the mounting plate 4, so that the mounting plate 4 is firmly fixed on the cone handle 1;

[0036] Then, the counterweight rod 7 is installed in the first fixing hole 403 in the appropriate set of fixing holes, and the knife handle 6 is installed in the second fixing hole 404. When installing the counterweight rod 7, the upper end of the counterweight rod 7 is first inserted into the corresponding first fixing hole 403, and then the fixing screw 5 outside the first fixing hole 403 is rotated, so that one end of the fixing screw 5 can enter the inside of the first fixing hole 403, thereby abutting against the plane of one side of the counterweight rod 7, and fixing the upper end of the counterweight rod 7 inside the first fixing hole 403. When installing the knife handle 6, the upper end of the knife handle 6 is first inserted into The fixing screw 5 outside the second fixing hole 404 is then rotated, so that one end of the fixing screw 5 can enter the second fixing hole 404, thereby abutting against the plane of one side of the tool handle 6, and fixing the upper end of the tool handle 6 inside the second fixing hole 404, thereby completing the fixed installation of the counterweight rod 7 and the tool handle 6, and the machine tool drives the mounting plate 4 to rotate, thereby driving the counterweight rod 7 and the tool handle 6 to rotate accordingly, and the workpiece 8 between the counterweight rod 7 and the tool handle 6 can be processed by the tool 601 on the tool handle 6;

[0037] When processing workpieces 8 of different sizes, the processing size can be changed by simply replacing the counterweight rod 7 and the tool handle 6 in the corresponding fixing hole group for installation.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
