Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention will be more clearly and clearly defined.
As shown in fig. 1 to 11, the multipurpose motorcycle transmission gear machining turning insert comprises a diamond-shaped turning insert substrate 100, a pair of semi-finishing tool tips 1 and a pair of rough-machining tool tips 6 are oppositely arranged on the upper surface of the turning insert substrate 100, a round fastening screw hole 9 is arranged at the center of the turning insert substrate 100, and negative chamfered cutting edges 7 are respectively arranged on the outer sides of the four sides of the turning insert substrate 100. This negative chamfer cutting edge 7 can improve the intensity of cutting edge to because the cutting edge has the wedge angle, enable the heat dispersion of cutting edge and improve greatly, thereby can effectively improve the cutter incorruptibility.
The semi-finishing cutter point 1 is at an angle of 80 degrees, and the rough machining cutter point 6 is at an angle of 100 degrees, so that the requirement on the strength of a cutter body in the cutting process of the cutter blade can be met, and the cutter blade is fully utilized. In addition, the semi-finishing cutter point 1 and the rough machining cutter point 6 both adopt arc structures, so that the impact resistance effect can be achieved, and the cutter point is prevented from being damaged under the mechanical impact load.
The inner sides of four sides of the turning tool substrate 100 are respectively provided with a chip breaker groove 3, the circumference of the fastening screw hole 9 is uniformly provided with four isolating protrusions 14, the isolating protrusions 14 are arranged on the upper surface of the turning tool substrate 100, the inner side of the semi-finishing tool tip 1 is respectively provided with a triangular tool tip protrusion 2, the inner side of the rough machining tool tip 6 is respectively provided with a quadrangular tool tip protrusion 5, the triangular tool tip protrusion 2 and the quadrangular tool tip protrusion 5 are both arranged on the upper surface of the turning tool substrate 100, a T-shaped cutting fluid guiding groove 8 and a cutting fluid guiding groove 15 are respectively arranged between the triangular tool tip protrusion 2 and the isolating protrusions 14, a Y-shaped cutting fluid guiding groove 4 and a cutting fluid guiding inclined plane 10 are respectively arranged between the quadrangular tool tip protrusion 5 and the isolating protrusions 14, a linear finishing blade 12 is respectively arranged on the outer side wall of the semi-finishing tool tip 1, the turning tool substrate 100 has a tool body supporting surface 16 at the bottom, four base liquid guiding grooves 13 are formed on the tool body supporting surface 16, the base liquid guiding grooves 13 are communicated with the fastening screw holes 9, and a base liquid guiding inclined surface 131 is respectively formed at the head of each base liquid guiding groove 13.
The cutting fluid guide groove 15 is provided with a tip mark 11. The cutter point mark numbers 11 can solve the problem that workers are difficult to identify when installing the cutter blade, and improve the working efficiency.
The linear wiper edge 12 has a length of about 1mm, and when used, the linear wiper edge 12 makes about 1 ° with respect to the feed direction of the tool as shown in fig. 12. The straight wiper blade 12 prevents the blade edge from being broken prematurely, and more importantly, improves the roughness of the machined surface even if the feed rate is increased under the original machining conditions.
In addition, the triangular cutter point bulge 2 and the quadrilateral cutter point bulge 5 can play a role in strengthening the strength of the cutter point, can guide the outflow of cutting chips, can increase the effective heat dissipation area of the cutter, and are beneficial to the heat dissipation of the blade. The chip breaker groove 3 can effectively control the shape of chips, so that C-shaped chips are easier to form in the cutting process.
In addition, by using the Y-shaped cutting fluid guide groove 4 and the T-shaped cutting fluid guide groove 8, continuous cutting fluid is supplied to the cutting area during cutting, and after the cutting fluid is temporarily stored in the chip breaker groove 3, the cutting fluid flows into the fastening screw hole 9 along the Y-shaped cutting fluid guide groove 4, the T-shaped cutting fluid guide groove 8 and the cutting fluid guide inclined surface 10, flows to the bottom of the blade, and finally flows out from the base portion fluid guide groove 13. The outflow route of the cutting fluid penetrates through the whole blade, a large amount of cutting heat is taken away in the outflow process of the cutting fluid, and the effect of reducing the cutting temperature of a cutting area can be achieved. Of course, the Y-shaped cutting fluid guide grooves 4 and the T-shaped cutting fluid guide grooves 8 may have other shapes.
In addition, the thickness of the multipurpose motorcycle transmission gear processing turning blade is about 5mm, the rear angle is about 8 degrees, and the front angle is about 12 degrees.
The multipurpose motorcycle transmission gear machining turning tool blade is compact in structure and strong in impact resistance, can avoid multiple tool changing under the condition of ensuring the precision of parts, greatly improves the machining efficiency of gears and reduces the production cost.
Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
