Abstract
The utility model discloses a double-sided dish milling cutter that groove processing was dodged to tegument cover, including handle of a knife (1), go up tool bit (2), it links to each other with tool bit (4) down through cutter arbor (3) to go up tool bit (2), tool bit (4) dress is equipped with on cutter arbor (3) down, is equipped with on this going up tool bit (2) and goes up blade (5), is equipped with under blade (6) on this tool bit (4) down. The upper blade and the lower blade are both indexable blades. The utility model discloses dodge groove terminal surface and process together by upper and lower blade respectively two of the tile lid, make the depth of parallelism of its both ends face better, stable in quality has reduced the risk that customer end installation became invalid. The processing efficiency is directly improved by one time, and the processing can be completed only by once clamping. Meanwhile, equipment and labor cost are saved, the operation intensity is reduced, the clamping error probability is reduced, and the quality stability of products is improved.
Description
Technical Field
The invention relates to a cutter, in particular to a machining cutter for a bush cover of an engine and a bush cover avoiding groove on a camshaft.
Background
With the continuous development of the times, the requirements of automobile engines on the machining efficiency and quality of various accessories are higher and higher, the tile cover avoiding groove (matched with the camshaft) is one of key parts of the tile cover, the tile cover avoiding groove needs to be clamped twice in the machining process, and the machining is finished by using an end milling cutter. The clamping is troublesome, the processing efficiency is low, and the repeated operation is easy to miss processing (especially new operators). Which may lead to the following results: the machining quality stability is not high, the dimension of the end face of the avoiding groove is out of tolerance due to the fact that the product is not machined or the clamping is not correct, the position of an engine camshaft is locked after a client installs the engine camshaft, the product performance is affected, and the client complains about a great deal; additional equipment and personnel are required to increase the shift to meet customer demand, resulting in increased machining costs.
Disclosure of Invention
The invention aims to overcome the defects and provide the double-sided disc milling cutter which only needs one-time clamping and one-time processing of two tile cover avoiding grooves.
The purpose of the invention is realized by the following technical scheme: the double-sided disc milling cutter comprises a cutter handle and an upper cutter head, wherein the upper cutter head is arranged on the cutter handle, the upper cutter head is connected with a lower cutter head through a cutter rod, the lower cutter head is arranged on the cutter rod, an upper blade is arranged on the upper cutter head, and a lower blade is arranged on the lower cutter head.
The upper blade and the lower blade are both indexable blades. The upper cutter head is provided with an upper blade through an adjustable screw.
After the method is adopted, the upper blade and the lower blade respectively process the end surfaces of the two avoidance grooves of the tile cover together, so that the parallelism of the two end surfaces is better, the quality is stable, and the risk of failure of the client installation is reduced. The two avoiding grooves of the original tile cover are processed in 60 seconds, the processing efficiency is directly doubled after the double-sided disc milling cutter is changed into the double-sided disc milling cutter, the processing can be completed only by once clamping, and the beat is increased to be within 30 seconds. And after the beat is promoted, an additional device is not required, the device and labor cost are saved, the operation intensity is reduced, the clamping error probability is reduced, and the quality stability of the product is improved.

The present invention will be described in further detail with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural view of the double-sided disc milling cutter of the present invention.
Fig. 2 is a bottom view of fig. 1.
Fig. 3 is a schematic structural view of the tile cap avoiding groove processed by the present invention.
Fig. 4 is a sectional view a-a of fig. 3.
Detailed Description
Referring to fig. 1 and 2, the double-sided disc milling cutter of the present invention includes a cutter handle 1 and an upper cutter head 2, wherein the upper cutter head 2 is mounted on the cutter handle 1, the upper cutter head 2 is connected with a lower cutter head 4 through a cutter bar 3, the lower cutter head 4 is mounted on the cutter bar 3, an upper blade 5 is mounted on the upper cutter head 2 (through an adjustable screw 7), and a lower blade 6 is mounted on the lower cutter head 4.
Wherein, the upper blade 5 and the lower blade 6 are both indexable blades so as to prolong the service life of the upper blade and the lower blade. The knife handle is connected with the special connector and clamped on the main shaft for processing.
The invention is applied to the automobile engine and used for the cutter that the evading groove (two, cooperate with camshaft to mount) processing of the tile cover, its upper, lower blade corresponds to two of the processing tile cover and dodges the groove separately, there are four blades on the upper, lower blade, two blades on the upper, lower blade cut while processing the tile cover and dodging the groove separately, the blade can be dismantled after wearing and tearing, use its other two blades of opposite side to process, has improved the service life of the cutter; and the distance L between the upper blade and the lower blade can be adjusted by 0.2mm up and down through the adjustable screw on the upper blade, so that the size of the distance L can be adjusted conveniently.
The invention is particularly suitable for independently processing the thrust surface of the tile cover. The tool bar 3 of the double-sided disc milling cutter of the present invention is made of a solid carbide, and the calculation methods of the range of use, the diameter of the tool holder, the distance between the upper and lower blades, etc. thereof are described in detail below according to the actual conditions of different tile caps.
As shown in fig. 1 to 4, the applicable scope of the double-sided disc milling cutter is as follows:
D＜D1；D3＜D2＜D4；L1＜L＜L2。
wherein: D. d1 is: the diameter of the cutter bar and the diameter of the tile cover avoiding groove;
d4 and D3 are: the tile cover avoids the upper limit size and the lower limit size of the groove;
d2 is: the diameter of the upper cutter head; l is: the distance between the upper blade and the lower blade;
l1 and L2 are: the tile cover avoids the upper and lower limit distance sizes of the two surfaces of the groove.
D < D1: in order to ensure that a sufficient safety distance exists between the cutter bar and the tile cover in the processing process and avoid the phenomenon of cutter collision (generally, a 1mm distance is reserved on a single side; in order to ensure the rigidity of the processing cutter, the cutter bar D can be designed to be as thick as possible according to the actual condition of the tile cover, and under the general condition, the diameter D of the cutter bar is more than or equal to 8 mm);
d3 < D2 < D4: the processing size of the cutter meets the technological size requirement;
l1 < L2: the machining size of the cutter meets the technological size requirement.
