When on horizontal milling machine, processing the T type groove of stretching-machine jaw with the lengthening slotting cutter, because slotting cutter long (as elongate rod), poor rigidity causes cutting speed slow (long processing time), the processing cost height, T type groove dimensional accuracy and surface roughness after the processing are poor, be difficult for reaching the drawing requirement, add man-hour, because the cutting speed of wire cutting machine tool own is slow with wire cutting machine tool, so long processing time (processing needs more than 4 hours), cost is also high.
When taking out the T type groove on the cage plate of heart compression mod with the end mill processing belt, because take out varying in size of heart hole, T type groove size on the cage plate is also different, will use the T type milling cutter that much varies in size like this, if add and break a cutter tooth man-hour because of carelessness, whole milling cutter is just scrapped, particularly big T type milling cutter value height has so just increased processing cost.
The utility model provides a kind of T type milling cutter, can change the cutter that breaks, and has reduced process time, has reduced cost of processing.
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model discloses a kind of T type milling cutter, the structural representation when being illustrated in figure 6 as this T type milling cutter maximum cutter being installed comprises: knife bar 1, broach shell 2, cutter 3, screw 4, key 5, edge bearing 6 and Morse taper shank 7, wherein:
Knife bar, use machined into, one is Morse taper shank (as shown in Figure 7), the other end is a circular shaft, the aperture that the diameter of circular shaft generally equals minimum cutter is φ 22mm normally, and there are three kinds of φ 22mm, φ 27mm and φ 32mm in the aperture of cutter commonly used, and the circular shaft end face has the screwed hole that is used for fixing cutter, has keyway (controlling cutter with key rotates together with cutter) on the circular shaft wall.
One end of knife bar is processed into Morse taper shank, helps being installed on the milling machine spindle.
Cutter is socketed on described broach shell, and is fixed in by screw on the circular shaft of described knife bar, and described cutter inboard has keyway, and tool surface has heavy stand hole 8, as shown in Figure 8, makes hold-down screw can place in the cutter end face.
Broach shell is placed in described knife bar circular shaft, and its aperture equals the diameter of described knife bar circular shaft, i.e. φ 22mm, and external diameter equals the aperture of cutter, and described broach shell inboard and outer wall all have keyway (as shown in Figure 9).
For the milling cutter that varies in size being installed with a knife bar, just need broach shell to connect in the middle of doing, the aperture of broach shell equals the knife bar diameter of round spindle, cylindrical equals three sword apertures, with milling machine process keyway (with key control with knife bar together, cutter rotates together)
Screw, supporting with described screwed hole as shown in Figure 10, cutter and knife bar are fixed as one.
Key as the linkage part of knife bar, cutter, broach shell and edge bearing, rotates them synchronously, because varying in size of cutter, the size of broach shell are also different, so the size of key is also different, as shown in figure 11, Chang Yong key has three kinds of (6mm * 6mm, 6mm * 8mm and 8mm * 8mm).
Different choice according to institute's use cutter is used different keys, when using the cutter of minimum-value aperture, can directly install with the key of a 6mm * 6mm, and need not to use broach shell, key with a 6mm * 8mm when using the aperture as the cutter of φ 27mm cooperates broach shell to install, this moment, this key connected knife bar in the lump, broach shell and cutter, as shown in figure 12, when using the aperture as the cutter of φ 32mm, cooperate the broach shell of corresponding size to install with the key of a 6mm * 6mm and the key of a 8mm * 8mm, the key of 6mm * 6mm is used to connect knife bar and broach shell, the key of 8mm * 8mm is used to connect broach shell and cutter, as shown in Figure 13.
Edge bearing places the gap of knife bar and cutter, and edge bearing commonly used has three kinds, and pore size is respectively φ 22.5mm, φ 27.5mm and φ 32.5mm, the pore size of edge bearing and thickness and knife bar circular shaft, and the size of cutter matches.
From above-mentioned technical scheme as can be seen, the utility model makes this T type milling cutter can change cutter by cooperatively interacting of knife bar, cutter, broach shell and edge bearing, thereby can finish different processing, need not to prepare many handles, multiple T type milling cutter, reduced to become to produce cost, and after cutter tooth breaks, only needed the tool changing tool to get final product, need not all change, further lower cost.
Combination T type milling cutter provided by the utility model, promptly be suitable for processing with horizontal milling machine, have and be suitable for processing with horizontal milling machine, can select according to concrete machining shape and processing capacity, strengthened the scope of application, and the utility model avoided the quality problems brought with lengthening slotting cutter processing T type groove, can process fast, thereby improved the crudy of T type groove, reduced process time.
From technique scheme as can be seen, the combination T type milling cutter that the utility model provides has been realized the replacing of cutter by the interlock effect of key, and is simple, convenient.
The disclosed combination of the utility model T type milling cutter can be finished above-mentioned process operation on vertical knee-type milling machine, as shown in Figure 15,9 for part makes up T type milling cutter, the lathe bed of 10 part vertical knee-type milling machines, and the process time spent is short, the crudy height, and this T type milling cutter can be changed dissimilar cutters as required, thereby can finish the operation that some can only carry out in the past on the vertical knee-type milling machine on horizontal milling machine, and it is more convenient to change cutter, thereby increase work efficiency, cut down finished cost.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
