Abstract
The utility model discloses a crankshaft molded left-rotating milling cutter, and belongs to the technical field of mills for milling machine processing. The crankshaft molded left-rotating milling cutter comprises a mill body and blade tables, wherein a mounting hole is formed in the center of the annular mill body; U-shaped grooves are formed on the blade tables; blades are arranged on the lateral side of the blade tables and U-shaped concave surfaces; and the blade tables form a zigzag shape along the annular lateral side of the mill body. The crankshaft molded left-rotating milling cutter has a simple and reasonable structure, and the tool manufacture has low requirement to a machine, so that the cost for the whole mill body is low; and in the tool using process, the blades are easy to replace, the mill body is protected from being broken, and the processed finished products can achieve the requirement of process accuracy.
Description
Technical field
The utility model relates to a kind of milling cutter, relates in particular to a kind of vehicle bent axle moulding left side milling cutter, belongs to milling machine processing and uses the milling cutter technical field.
Background technology
The accuracy of manufacture of bent axle and working (machining) efficiency will be directly connected to the development of industry, and at present, state's inside crankshaft normally adopts milling process processing in the processing to its trunnion and rod journal.The outer milling cutter of existing integral one-piece crankshaft moulding is easy to damage cutter hub after the breaks down in process, damage the back cutter hub and be difficult to repair its original precision, thereby cause whole cutter hub to scrap, and wastes greatlyyer, has increased user's cutter expense; In addition, this type milling cutter is the import cutter hub mostly, and its processing cost is higher, and the blade process requires height to power, the rigidity of lathe, and the cutter manufacturing is high to the machine tool accuracy requirement, causes production cost high.
The utility model content
The purpose of the utility model is: a kind of bent axle moulding left side milling cutter is provided; Solve the easy damage cutter hub of existing bent axle moulding institute use milling cutter existence, the technical problem that processed finished products does not reach precision, thereby can effectively solve the problem that exists in the above-mentioned prior art.
The purpose of the utility model is to realize through following technical proposals: a kind of bent axle moulding left side milling cutter; Comprise cutter hub and blade platform; Said cutter hub is an annular, and its center is an installing hole, establishes U-lag on the said blade platform; Blade is located at its side and U-shaped concave surface, and blade platform forms zigzag along the annular side of cutter hub.
As a kind of optimal way, blade platform is fixed through hexagon socket cap head screw and cutter hub.
As further optimal way, between above-mentioned cutter hub and blade platform, also be provided with alignment pin.
As a kind of optimal way, blade is fixed through plum blossom screw and blade platform.
As a kind of optimal way, be uniformly distributed with six logical counterbores around the said installing hole.
The effect of part is following in the utility model:
Hexagon socket cap head screw: be used to connect blade platform and cutter hub, make both be fastenedly connected, prevent the loosening of process.
Alignment pin: be used to strengthen the connection between blade platform and the cutter hub.
Compared with prior art, the beneficial effect of the utility model: the utility model bent axle moulding left side milling cutter construction is simple, reasonable, and the cutter manufacturing requires low to lathe, make that the cost of whole cutter hub is low; In the cutter use, its blade exchange is easy, and cutter hub is difficult for being damaged, and the finished product that processes can reach the craft precision requirement.
Description of drawings
Fig. 1 is the structural representation of the utility model bent axle moulding left side milling cutter;
Fig. 2 is the sketch map that the lateral parts of Fig. 1 cuts open;
Fig. 3 is the structural representation of blade platform.
Among the figure: the 1-cutter hub, the 2-blade platform, the 3-alignment pin, the 4-hexagon socket cap head screw, the 5-blade, 6-plum blossom screw, the 7-installing hole, 8-leads to counterbore, 9-U shape groove.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
Disclosed all characteristics in this specification, or the step in disclosed all methods or the process are except the speciality of mutual repulsion and/or the step; All can make up by any way; Only if special narration all can be replaced by other equivalences or the alternative features with similar purpose, promptly; Only if special narration, an embodiment in a series of equivalences of each characteristic or the similar characteristics.
Like Fig. 1, shown in Figure 2; The utility model bent axle moulding left side milling cutter comprises cutter hub 1 and blade platform 2, and said cutter hub 1 is an annular, and its center is an installing hole 7; Be uniformly distributed with six logical counterbores 6 around the said installing hole 7, whole milling cutter be installed on the milling machine through installing hole 7.As shown in Figure 3, establish U-lag 9 on the said blade platform 2, blade 5 is located at its side and U-shaped concave surface, and the quantity of the size of blade platform and upward U-lag 9 settings thereof can decide according to the size of cutter hub and actual processing work.Blade platform 2 forms zigzag along the annular side of cutter hub, and when processing this milling cutter, the medial surface of blade platform is identical with the cutter hub radian, when making both fixedly, can fit each other closely.Because the multidigit setting of blade 5, the blade on the blade platform different facial produces the distinct cutting effect, and therefore, process velocity and machining accuracy are able to guarantee.Blade platform 2 is fixing with cutter hub 1 through hexagon socket cap head screw 4, between above-mentioned cutter hub 1 and blade platform 2, also is provided with alignment pin 3, and hexagon socket cap head screw is used to connect blade platform and cutter hub.The setting of alignment pin makes blade accurate positioning on blade platform, and clamping is firm, prevents that in process it is loosening.Blade 5 is fixing with blade platform 2 through plum blossom screw 6.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
