Abstract
The utility model discloses a machine-used internal slotted cutter which comprises a cutter shank, a spring, a cutter arbor, a first pin shaft, an extensible sleeve, a second pin shaft and a cutter head, wherein the tail part of the shank is tapered; the inner hole at the front end of the shank is matched with the extensible sleeve; the extensible sleeve presses the spring on the end surface of the inner hole of the cutter shank, and is a stepped shaft; a flat groove is formed on the stepped shaft in the axial direction; the cutter arbor is mounted in the flat groove; a part, extending into the extensible sleeve, of the cutter arbor is flat; the cutter arbor is connected with the cutter shank through the first pin shaft passing through a U-shaped groove on the cutter arbor; the cutter arbor is connected with the extensible sleeve through the second pin shaft; a bolt is used for locking the second pin shaft; and the cutter head is mounted in a hole at the front end of the cutter arbor, and pressed through the adjusting screw. After the inner hole of a part is processed, a drill bit is demounted, and the slotted cutter is replaced, when a main shaft of a machine tool drives the shank to move downwards, the first pin shaft also moves downwards and slides in the U-shaped groove of the cutter arbor, so that the cutter arbor rotates around the second pin shaft and further drives the cutter head to carry out the feed cutting.
Description
Technical field
The utility model relates to machining hole and uses the groove cutter with the machine of circlip groove.
Background technology
In mechanical industry, the hole is installed in the circular hole with back-up ring, as the axially-movable of restriction parts.This structure is because of simple in structure, and is easy to use, reliable, is the normal a kind of version that adopts of many parts.At present, following several kinds of processing methods are generally taked with the processing of circlip groove in the hole: 1, less like part, can on lathe, process the workpiece of rotation with the inside groove cutter; 2, bigger and complex-shaped like part, then must on boring machine, process, but this processing mode is more time-consuming owing to proofreading and correct and measuring, so efficient is not high by facing head.And it is when workpiece is overweight, very high to the requirement meeting of boring machine equipment.
Summary of the invention
The utility model problem to be solved provides a kind of machine and uses the inside groove cutter, and it is bigger and when complex-shaped at part, can process with circlip groove the hole easily.
A kind of machine of the utility model is used the inside groove cutter, it is characterized in that: it comprises handle of a knife, spring, knife bar, first bearing pin, telescopic, second bearing pin, cutter head; The afterbody of handle of a knife has tapering, and the endoporus of its front end matches with telescopic, and telescopic is pressed in spring on the end face of handle of a knife endoporus; Telescopic is a multidiameter, and it is processed with flat groove vertically, in the flat groove knife bar is housed, and the part that knife bar stretches in the telescopic is flat side; Knife bar links to each other through first bearing pin that from its U-lag, passes with handle of a knife, and knife bar links to each other through second bearing pin with telescopic, and screw is with second lock clasp; In the hole of knife bar front end cutter head is housed, and it is compressed through the adjustment screw.
After the endoporus of part had processed, den bohrkopf abbauen was changed this groove cutter, and promptly the tapering afterbody through handle of a knife links to each other with the main shaft of lathe.The front portion of telescopic is inserted and has been bored in the good hole of boring; Play the guiding role, when machine tool chief axis drive handle of a knife moved down, first bearing pin also moved down and in the U-lag of knife bar, slides; Knife bar is rotated around second bearing pin, and then the drive cutter head carry out the feeding cutting; The hole that is processed confirms that by the size of cutter head self diameter of groove is then controlled by the rotational angle of knife bar with the groove width of circlip groove.Therefore, this novel machine is bigger and when complex-shaped at part with the inside groove cutter, can process with circlip groove the hole easily.
Description of drawings
Fig. 1 is the structural representation of the utility model hand with the inside groove cutter.
The specific embodiment
Can know that from Fig. 1 a kind of machine of the utility model is used the inside groove cutter, it comprises handle of a knife 1, spring 2, knife bar 3, first bearing pin 4, telescopic 5, second bearing pin 9, cutter head 10; The afterbody of handle of a knife 1 has tapering, and the endoporus of its front end matches with telescopic 5, and telescopic 5 is pressed in spring 2 on the end face of handle of a knife 1 endoporus; Telescopic 5 is a multidiameter, and it is processed with flat groove vertically, and knife bar 3 is housed in the flat groove, and the part that knife bar 3 stretches in the telescopic 5 is flat side; Knife bar 3 links to each other through first bearing pin 4 that from its U-lag, passes with handle of a knife 1, and knife bar 3 links to each other through second bearing pin 9 with telescopic 5, and screw 8 is with 9 lockings of second bearing pin; In the hole of knife bar 3 front ends cutter head 10 is housed, and it is compressed through adjustment screw 11.Wherein, the tapering of handle of a knife 1 afterbody is Morse's taper or other tapering like BT etc.
Position for control flume; As a kind of optimal way of the utility model, machine also comprises positioner with the inside groove cutter, and positioner is made up of bearing 6, positioning sleeve 7; Positioning sleeve 7 is enclosed within through bearing 6 on the outer surface of telescopic 5, and bearing 6 is pressed on the step surface of telescopic 5.
After the endoporus of part has processed, the position of adjusting positioning sleeve 7 according to the position of groove to be processed earlier, den bohrkopf abbauen is changed this groove cutter, and the Morse taper shank that promptly passes through handle of a knife 1 links to each other with the main shaft Mohs hole of brill (boring) bed and gets final product.During machining hole, the front portion of telescopic 5 is inserted and has been bored in the good hole of boring, play the guiding role; Move down when machine tool chief axis drives handle of a knife 1, when positioning sleeve 7 was run into part surperficial, first bearing pin 4 also moved down and in U-lag, slides, and knife bar 3 is rotated around second bearing pin 9, and then drove cutter head 10 and carry out the feeding cutting.In this novel groove cutter, the hole that is processed confirmed by positioning sleeve 7 with the position of circlip groove, and groove width is definite by the size of cutter head 10 self, and the diameter of groove is then controlled by the rotational angle of knife bar 3.Therefore, the groove in same aperture gets final product with a kind of this groove cutter of specification.This groove cutter can manufacture series of products, to satisfy the processing request of different apertures inside groove.So long as hole that common driller can get out or borehole, this groove cutter can use.If with the afterbody of handle of a knife is that the caudal peduncle of BT or other form also can use on numerical control machining center.The main feature of the utility model is motor-driven, quick, easy.
The movement locus of this groove jet blade sees it is one section camber line from microcosmic; Therefore grooved of processing and drawing requirement be difference slightly, but generally can be controlled in the margin of tolerance, does not only influence use; On the contrary because the direction of this circular arc makes the effect after install with back-up ring in the hole more reliable.
