Abstract
The utility model discloses a micro-adjusting tool holder, which is suitable for clamping on the machine as the micro-feed device. The utility model is characterized in that the screw connecting position of a sliding cutter sleeve and a screw mandrel is additionally provided with a conic nut used to eliminate the thread gap, a fixed sleeve is directly provided with a square clamping seat for clamping, and the flat key of the fixed sleeve is utilized. So the feed precision is 1-2 times higher than the common lathe, and the work efficiency is 3-4 times higher than the common lathe. The labour intensity is decreased, and the dimension precision and the surface quality of the workpiece are improved. The utility model has the advantages of small size, simple structure, convenient operation and low cost and can also be used in the miller, the boring mill and the driller to process the macropore with the diameter more than 80 mm.
Description
A kind of Micro-adjusting tool holder relevant with fine finishining can be used for the macropore of finished diameter more than 80mm on milling machine, boring machine, the drilling machine, is particularly suitable for meticulous turning and adds man-hour, and directly clamping is made microfeed on the square tool post of all kinds of engine lathes.
All kinds of engine lathes are found everywhere, and account for more than 95% of various difference in functionality lathe sums.The square tool post of present various engine lathes all is to adopt general T type screw drive, the dovetail groove guiding.Because the gap between screw rod and the nut is bigger, operator's turning handle, the numerical value that reflects on the dial and the numerical difference between of actual feeding are brought certain difficulty apart from bigger to finish turning, and the operator has not very slightly, will cause product rejection.Sometimes the operator knows that the size of workpiece requires to also have in the 10 μ m apart from drawing perfectly well, just dare not continue feed, has to use accessory manipulations such as rubber and file.Though dimensional requirement has reached like this, workpiece surface quality has been subjected to destruction.In addition, in order to reach the drawing requirement, the operator wants careful repeatedly test run nervously, and operating efficiency can't improve, and high-precision Digit Control Machine Tool is born already, owing to cost an arm and a leg, the user is still rare.
The purpose of this utility model provides and a kind ofly can be clamped on the lathe, realizes the Micro-adjusting tool holder of accurate feeding.It can improve the machining accuracy of work piece, improves accurately machined efficient, alleviates operator's labour intensity.
The utility model is the same with the kind of drive of engine lathe square tool post, still adopts screw drive.To achieve these goals, the utility model is set up conical nut at the place that is spirally connected of slip broach shell and screw mandrel, to eliminate the thread pitch between slip broach shell and the screw mandrel; Adopt flat key to connect between the utility model slip broach shell and the fixed muffle, turning handle, screw mandrel drives the slip broach shell and slidably reciprocates, and does not rotate, so that fixed muffle and flat key play good guide effect; The utility model fixed muffle outer round surface is provided with the square grip slipper of projection vertically, and clamping is on lathe easily.
Regulate the scope of thread pitch between slip broach shell and the screw mandrel in order to increase conical nut, reach eliminate its two between the purpose in gap, the slip broach shell is provided with one section circumferentially uniform at least three long through groove of taper thread, and the length of groove is got taper thread length and added 1～5mm.
In order to adjust the elongation of knife bar easily, make it be in stress preferably, the hole of mounting cutter is processed into columniform on the slip broach shell.The direction in hole look processing excircles still in circle, be located at respectively the slip broach shell axis direction and with the direction of axis normal.The end in hole is provided with pinching screw, in order to clamp handle of a knife.The utility model is made circle usefulness in the turning, also can set up a tool rest on the slip broach shell, and process the hole of a clamping cutter, and this hole is perpendicular to the cylindrical hole of clamping cutter on the slip broach shell.
In order to prevent that flat key from coming off when the slip broach shell slidably reciprocates, flat key must adopt screw or pin to be fixed on fixed muffle or the slip broach shell.
The utility model volume is little, convenient mounting and clamping, and the same directly clamping with regular turning tool is on the square tool post of engine lathe, and is several according to the clamping simultaneously of processing needs.Especially the utility model has been set up conical nut and has been eliminated thread pitch, utilizes fixed muffle and flat key guiding, makes the utility model feed accuracy improve 1～2 times, during finish turning, the operator need not to carry out repeatedly test run, and operating efficiency improves 3～4 times, greatly reduces working strength of workers.The utility model feed accuracy height, the operator can select the optimized cutting amount easily, does not need with rubber, file, provides advantageous conditions for improving workpiece surface quality.In addition, the utility model is simple in structure, the amorphism complicated parts, and easy to process, cost of manufacture is low.The utility model also can be applicable on milling machine, boring machine, the drilling machine, the macropore of finished diameter more than 80mm.
Below in conjunction with drawings and Examples the utility model is described in further detail, but the utility model is not subjected to the restriction of these embodiment.
