Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings.
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
In the description of the present utility model, it should be understood that the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.
In the description of the present utility model, unless otherwise specified and defined, it should be noted that the terms "mounted," "connected," and "coupled" are to be construed broadly, and may be, for example, mechanical or electrical, or may be in communication with each other between two elements, directly or indirectly through intermediaries, as would be understood by those skilled in the art, in view of the specific meaning of the terms described above.
As shown in fig. 2, the application provides a cutter for processing a large-sized end face deep ring groove, which comprises a cutter bar 1, a cutter head 2 and a cutter blade 4, wherein the cutter bar 1 and the cutter head 2 are combined into an L shape, a reinforcing stop block 5 is connected to the middle part of the cutter bar 1, and the direction of the reinforcing stop block 5 is consistent with the direction of the cutter head 2, so that the whole shape of the cutter bar 1 is of an F shape. And the reinforcing stop block 5 and the cutter bar 1 are integrally formed. According to the machined parts, the thickness of the cutter bar 1 can be increased, namely, the rigidity of the cutter bar 1 can be obviously improved under the condition of increasing relatively low cost, and the integral rigidity of the cutter can be further increased by adding the reinforcing stop block 5.
The angle between the inner side of the connection between the tool bit 2 and the tool bar 1 and the outer side of the tool bit 2 is set to 9 ° as shown in fig. 2, and the angle between the upper part of the lower tool bit 2 of the present embodiment is changed according to the different angles of the parts as shown in fig. 3, which is designed to reduce the weight of the whole tool, and at the same time, if the lower part and the upper part of the tool bit 2 are parallel to the tool bar 1 and perpendicular to the tool bar 1, interference with the parts is possible. The cutter bar 1 is provided with an avoidance groove 6, and parts are avoided during processing.
The blade 4 is arc-shaped; the blade 4 is connected with the cutter head 2 through the connecting part 3, and the connecting part 3 is connected with the cutter head 2 through a screw. Instead of rotating the blade 4 of fig. 2 by 90 ° and mounting the arc turning tool on the tool holder 1 in the cutting direction, the arc blade 4 is mounted on the tool holder 2 in the length direction of the connecting portion 3, i.e., the arc blade 4 is connected to the connecting portion 3 and then aligned with the length direction of the front end of the tool holder 2, as shown in fig. 2.
When the cutter blade 4 is circular, the main cutting force born by the cutter during processing is tangential to the rotation of the part, and the cutting force is born by the cutter bar 1 as a whole rather than by the bolts for fastening the cutter, so that the cutter is stressed more uniformly during mounting, and the risks of cutter breakage and cutter breakage are reduced; and the whole tool face of the arc turning tool can be machined, so that all faces of the annular groove can be flexibly machined without adjusting the angle of the tool, the number of times of tool changing during machining is reduced, and the machining time is shortened.
As shown in fig. 3, the size of the circular arc turning tool is selected according to the width of the end of the cutter bar 1, that is, the width M of the connection portion between the cutter blade 4 and the connection portion 3 is greater than the thickness N of the connection portion 3, that is, the diameter of the circular arc turning tool must be greater than the width of the end of the connection portion 3, and the thickness of the connection portion 3 is slightly smaller than the thickness of the end of the cutter head 2. As shown in fig. 4, the width D of the cutter head 2 is larger than the width H of the blade 4. When each tool is replaced, the connecting part 3 and the blade 4 are only required to be detached and replaced, and the tool bar 1 and the tool bit 2 can be continuously used.
During machining, in order to enable smooth switching, chips are not accumulated in the annular groove, and machining efficiency and machining accuracy are affected. In the present embodiment, a cutting method is adopted in which the cutting depth is reduced and the feed amount is greatly increased during machining. The chips cut by the method are short arc-shaped chips, and the chips can be rapidly discharged under the action of centrifugal force due to the fact that the feeding amount is large and parts rapidly rotate, so that the chips are very smooth in chip removal. And after actual multiple times of machining, the arc turning tool using the cutting mode is found to be less in abrasion, and the cutter still maintains good quality after a plurality of parts are machined, so that the cutter can be used continuously. The method obviously improves the service life of the cutter, thereby reducing the use cost of the cutter. If the cutting depth is increased, the cutting force to which the tool is subjected as a whole increases significantly, increasing the risk of damage to the tool.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
