Abstract
The utility model discloses a milling cutter mounting structure, and particularly relates to the technical field of machining. The utility model solves the problems of low replacement speed and low part machining efficiency of the existing milling cutter during installation.
Description
Technical Field
The utility model belongs to the technical field of machining, and particularly relates to a milling cutter mounting structure.
Background
Currently, a numerical control milling cutter is an important factor of numerical control machining, and conventional general milling cutters comprise flat bottom end milling cutters, round nose milling cutters, ball nose milling cutters and the like. However, because of multiple production tasks, different product structures, complex and various design and technical requirements, the actual production process often encounters the problems that special cutters are needed to finish the processing of parts, such as the special-shaped groove structures of non-standard angle external C angle, external R, internal R or dovetail shape on the parts, and some structural features can be processed in a curved surface 'approaching' mode in a numerical control programming mode, but the processing time is long, the efficiency is low, the quality of partial surface processing is poor, and the like. The forming tool is also used for processing, and the forming tool is required to be designed, customized and purchased, so that the problems of poor universality, low use frequency, long customization purchasing period, influence on the scheduling of production tasks, minimum requirement on quantity, high purchasing and use cost and the like exist. In addition, the cutter is very firmly fixed on the cutter arbor, and when often using and need to change, need take very big time to take out to change, reduced part machining efficiency.
Disclosure of Invention
The utility model provides a milling cutter mounting structure, which aims to solve the problems of low replacement speed and low part machining efficiency of the existing milling cutter during mounting.
The technical aim of the utility model is realized by the following technical scheme: the utility model provides a milling cutter mounting structure, includes the cutter arbor, the inside of cutter arbor is opened there is the mounting groove, the inside detachable connection of mounting groove has the blade, the screw that sets up relatively is opened respectively to the both sides of mounting groove, threaded connection has fastening bolt in the screw, two fastening bolt common threaded connection is on the blade, be equipped with the dead lever on the terminal lateral wall of mounting groove, fixedly connected with spring on the dead lever, the free end and the blade of spring offset.
Principle and effect of the technology: when the blade is required to be fixed on the cutter bar, the blade is only required to be inserted into the mounting groove, and then two fastening bolts are screwed in from the threaded holes to be connected with the blade in a threaded manner, so that the blade can be fixed on the cutter bar, and the blade can be quickly replaced.
Further, the two threaded holes are I-shaped.
By adopting the scheme, the screw cap of the fastening bolt is conveniently attached to the cutter bar.
Further, the blade is attached to the mounting groove.
By adopting the scheme, the vibration of the blade during operation can be reduced.
Further, the right end of the blade is provided with a blade, and the blade is a concave fillet.
By adopting the scheme, the convex R structure can be directly milled on the part through the concave round angle.
Further, the free height of the spring is greater than the length of the fixed rod.
By adopting the scheme, the stability of the blade during operation can be improved.
Compared with the prior art, the utility model has the beneficial effects that: not only can the fixed milling cutter blade be replaced quickly, but also the blade can be kept stable during operation.
Drawings
Fig. 1 is a schematic structural view of a milling cutter mounting structure according to the present utility model;
in the figure: 1. a cutter bar; 2. a mounting groove; 3. a blade; 4. a blade; 5. a threaded hole; 6. a fastening bolt; 7. a fixed rod; 8. and (3) a spring.
Detailed Description
The following is a detailed description of the embodiments.
Examples: as shown in fig. 1, a milling cutter mounting structure comprises a cutter bar 1, wherein a cylindrical mounting groove 2 is formed in the right side of the inside of the cutter bar 1, and the right end of the mounting groove 2 penetrates through the right end of the cutter bar 1. The blade 3 can be detachably connected in the mounting groove 2, the right end of the blade 3 is provided with the blade 4, and the blade 4 is a concave fillet, so that a convex R structure can be directly milled on a part through the concave fillet. The cutter arbor 1 is last to open the screw hole 5 that is located mounting groove 2 upper and lower both sides, and two screw holes 5 are the I shape as a whole, and equal threaded connection has fastening bolt 6 in two screw holes 5, and two fastening bolt 6 common threaded connection are on blade 3. The left side wall of the mounting groove 2 is welded with a fixing rod 7, the outer side of the fixing rod 7 is welded with a spring 8, the free height of the spring 8 is larger than the length of the fixing rod 7, and the free end of the spring 8 abuts against the left end of the blade 3.
When the blade 3 is required to be installed, the blade 3 is only required to be inserted into the installation groove 2, the left end of the blade 3 is propped against the spring 8, and then the two fastening bolts 6 are respectively screwed into the cutter bar 1 from the threaded holes 5 until the two fastening bolts 6 are connected onto the blade 3 in a threaded mode. Thus, the blade 3 is fixed on the cutter bar 1, not only is the replacement convenient, but also the blade 3 can be more stable in operation.
The foregoing description of the embodiments of the present utility model will not be repeated for all common sense of specific construction and characteristics known in the art, and it should be noted that, for those skilled in the art, modifications and improvements can be made without departing from the construction of the present utility model, and these should also be regarded as the protection scope of the present utility model, which does not affect the effect of the implementation of the present utility model and the practical applicability of the patent. The protection scope of the present utility model is subject to the content of the claims, and the description of the specific embodiments and the like in the specification can be used for explaining the content of the claims.
