Abstract
The utility model discloses a clamping device for taper shank milling cutter, consisted of a clamping set (2) and a thread block (4). The thread block (4) is located in the strip groove of a machine tool axis (5), the clamping set (2) with internal thread is covered on the machine tool axis, one end of the clamping set is connected with the thread block (4), and the other end is a pressing surface with blade hole in the centre. The diameter of the blade hole is less than the diameter of the taper sleeve (3) in the machine tool. The utility model solves the problem that the taper sleeve is off the main axis in the process of equipment operation, cutting tool is ensured not to be off the main axis because of the wearing of taper hole or vibration in the process of cutting to avoid incidents.
Description
Technical field
The utility model belongs to a kind of clamping device that is used for taper-shank cutter, is applicable to common horizontal boring machine installation taper-shank cutter and drill bit.
Background technology
Functions such as homemade T68 horizontal boring machine integrates boring, mills, brill, line are used very extensive at mechanical processing industry.This equipment will be installed taper-shank cutter or taper-shank drill milling, boring and add man-hour in tapered bore of machine tool spindle, between the taper shank of cutter and the machine tool chief axis endoporus by the latching characteristics location of Mohs sleeve, clamp, realize transmitting moment of torsion, the function of cutting workpiece.After the equipment military service for many years, because frequent mounting or dismounting dress cutter causes tapered bore of machine tool spindle and conic sleeve appearance wearing and tearing to a certain degree, and then reduced coupling mechanism force between the two.In addition, owing in Milling Process and drilling process, can produce vibration inevitably, the wearing and tearing of vibration and taper hole are bigger to the clamping influence of cutter, usually because the coupling mechanism force deficiency, conic sleeve and main shaft break away from suddenly in appearance milling or the drilling process, the phenomenon of skidding in spindle hole causes cutter to scratch the appearance of situations such as finished surface.This phenomenon has not only influenced the crudy of product, and accidents caused easily.
Summary of the invention
The purpose of this utility model provides a kind of clamping device that is used for taper-shank cutter, problem in order to conic sleeve and main shaft disengaging in the solution equipment operation process, make it guarantee that cutter can not break away from machine tool chief axis because of taper hole wearing and tearing or vibration, avoids having an accident in working angles.
The purpose of this utility model can adopt following technical scheme to realize: it is made of gripping sleeve and threaded block, threaded block is positioned at the bar shaped elongated slot of machine tool chief axis, gripping sleeve is enclosed within on the machine tool chief axis, its inside has internal thread, one end of gripping sleeve is connected with threaded block, the other end is the seal face that the middle part has tool bore, and wherein the diameter of tool bore is less than lathe internal taper sleeve outer end diameter.
Have a dome platform on the cylindrical of described gripping sleeve, and on the dome platform, be evenly equipped with and tighten the hole.
After gripping sleeve of the present utility model and threaded block tighten by screw thread, gripping sleeve will be pressed on the conic sleeve in the lathe in the spindle taper hole, thereby play the effect that increases clamping force, prevent that conic sleeve in use breaks away from machine tool chief axis, avoids having an accident.The utility model is simple to operate, utilize aperture uniform on the gripping sleeve cylindrical to use hook spanner to tighten use for operating personnel, dome platform on the cylindrical can be when lathe be worked simultaneously, guide cuts liquid flows on the platen, avoid cutting fluid to carry foreign material and flow into lathe inside, influence the precision of main shaft along machine tool chief axis.

Fig. 1 is the schematic diagram of taper-shank cutter clamping device.
Among the figure: 1, taper-shank cutter, 2, gripping sleeve, 3, conic sleeve, 4, threaded block, 5, machine tool chief axis, 6, seal face, 7, the dome platform, 8, tighten the hole
Specific embodiments
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 1: the utility model mainly is made of gripping sleeve 2 and threaded block 4, and threaded block 4 is positioned at the bar shaped elongated slot of machine tool chief axis 5, and present embodiment adopts two threaded blocks 4.Gripping sleeve 2 is enclosed within on the machine tool chief axis 5, and its inside has internal thread, and an end of gripping sleeve 2 is connected with threaded block 4, and the other end is the seal face 6 that the middle part has taper-shank cutter 1 tool bore, and wherein the diameter of tool bore is less than lathe internal taper sleeve 3 outer end diameters.Have a dome platform 7 on the cylindrical of gripping sleeve, on dome platform 7, be evenly equipped with and tighten hole 8.
Its assembling process is as follows: the conic sleeve 3 of earlier taper-shank cutter 1 being packed into, the machine tool chief axis 5 of again conic sleeve 3 being packed into, afterwards, two threaded blocks 4 are inserted in the elongated slot of machine tool chief axis 5, after installing, at last gripping sleeve 2 is enclosed within on the machine tool chief axis 5, rotates gripping sleeve 2 by hand, its internal thread is meshed with the external screw thread of threaded block 4, re-uses hook spanner gripping sleeve 2 is tightened.
After the installation, gripping sleeve 2 is pressed on the end face of conic sleeve 3, conic sleeve 3 has been played the effect of axial compression, increase the coupling mechanism force between conic sleeve 3 and the machine tool chief axis 5, avoided conic sleeve 3 to be subjected to the generation of external force effect and machine tool chief axis 5 break-offs in the course of the work effectively.
Claims (2)
1, a kind of clamping device that is used for taper-shank cutter, it is characterized in that: it is made of gripping sleeve (2) and threaded block (4), threaded block (4) is positioned at the bar shaped elongated slot of machine tool chief axis (5), gripping sleeve (2) is enclosed within on the machine tool chief axis, its inside has internal thread, one end of gripping sleeve is connected with threaded block (4), and the other end is the seal face (6) that the middle part has tool bore, and wherein the diameter of tool bore is less than lathe internal taper sleeve (3) outer end diameter.
