Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model.

[0022] In addition, the terms “first”, “second”, “third”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0023] In addition, the terms "horizontal", "vertical", "overhanging", etc. do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0026] like Figure 1-Figure 2 As shown, the cemented carbide tool processing tooling includes a mounting base, a first rotating mechanism 2 arranged on the mounting base, a mounting plate 5 connected to the first rotating mechanism 2, and an adjusting arm 6 connected to the mounting plate 5; a tool clamping port 7 is arranged at the upper end of the adjusting arm 6, and a second rotating mechanism is arranged between the adjusting arm 6 and the mounting plate 5; a docking connection plate 1 is arranged at the bottom of the mounting base, and a plurality of connecting grooves 3 are arranged on the circumferential surface of the docking connection plate 1.

[0027] Generally speaking, grinding the cutting edge includes two steps: rough grinding and fine grinding. Rough grinding of the front cutting edge: First, use a coarse grinding wheel to rough grind the front cutting edge to remove welding slag and uneven parts on the surface. Rough grinding of the main and auxiliary flank faces: Then, rough grind the main and auxiliary flank faces, paying attention to controlling the feed rate and grinding depth to avoid excessive cutting force and heat. Rough grinding of the tool tip arc: Finally, rough grind the tool tip arc to make its shape meet the design requirements. Fine grinding of the front cutting edge: Use a fine grinding wheel to fine grind the front cutting edge to improve the surface finish and precision. Fine grinding of the main and auxiliary flank faces: Also use a fine grinding wheel to fine grind the main and auxiliary flank faces to ensure the straightness and sharpness of the cutting edge.

[0028] Compared with the prior art, in the prior art, the grinding methods of cemented carbide tools include manual grinding and mechanical grinding. Manual grinding is suitable for small-batch production and is flexible and convenient; mechanical grinding is suitable for large-scale production and can improve grinding efficiency and accuracy. When choosing a grinding method, it should be selected according to actual conditions and needs. However, relatively speaking, due to the complexity of the blade surface of some cemented carbide tools, such as milling cutters, which have multiple cutting edge surfaces, continuous position adjustment is required during grinding to meet the grinding of different edge positions.

[0029] In the present invention, two rotating mechanisms are provided, and the direction can be adjusted by connecting to a motor control or by manual control. During grinding, changes in multiple directions can be made, making it more convenient to use a grinding wheel to process the tool edge.

[0030] The mounting plate 5 is a triangular plate, and a supporting rib connecting hole 4 is provided below the side of the triangular plate. After adding the click, the mounting plate 5 will bear a greater gravity, and at this time, the stability of the mounting plate 5 can also be increased by providing a supporting rib.

[0031] The adjusting arm 6 is installed on the upper side of the triangle plate.

[0032] The second rotating mechanism comprises a motor connection support, and a coupling connected to the motor output shaft is arranged in the motor connection support. The motor connection support and the adjustment arm 6 are arranged on both sides of the mounting plate 5 respectively.

[0033] The butt connection disk 1 is provided with a plurality of fixing threaded through holes on its disk surface.

[0034] In actual use, when manual grinding is performed, the tooling equipment provided by the utility model can be installed on a fixed base 8 through the docking connection plate 1, such as Figure 2As shown, the tool is then fixed to the work surface by a fixed base 8, and a driving motor is installed on the side of the fixed base 8 to control the first rotating mechanism 2 to rotate. The first rotating mechanism 2 is used to rotate the adjusting arm 6 to adjust the position of the tool. The second rotating mechanism is used to control the adjusting arm 6 to rotate, so that the height of the tool can be adjusted to make it easier to grind different blade surfaces of the tool.

[0035] As a further solution, the tool clamping port 7 can be designed as a rotatable triangular claw disk, and the triangular claw disk can be controlled by a motor to rotate to realize the workpiece rotation. The application of triangular claw disk control in processing machinery is very mature, and it is only a possible further solution here, and no further repetition will be given.

[0036] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
