Abstract
The utility model discloses a collet structure for preventing a cutting tool from sliding. The collet structure for preventing the cutting tool from sliding comprises a revolving shaft, an ER collet and a cutting tool; the ER collet is clamped in the revolving shaft; a tail portion of the cutting tool stretches out from the ER collet and extends to an inner taper hole of the revolving shaft; an ER nut is arranged at the front end of the ER collet; the ER nut is connected with the revolving shaft through threads to clamp the ER collet and the cutting tool; bilateral sides of the revolving shaft are provided with two screw holes; screws are screwed into the screw holes to abut against two flat surfaces on the tail portion of the cutting tool. According to the collet structure for preventing the cutting tool from sliding, the ER collet clamps the cutting tool, the ER collet is clamped inside the revolving shaft, the ER nut compresses the ER collet, the clamping force is larger when the ER nut compresses tightly, and the sliding possibility of the cutting tool is small; the screw holes are formed in the external lateral wall of the revolving shaft, the screws are arranged inside the screw holes, the two screws can abut against the two flat surfaces on the tail portion of the cutting tool, the cutting tool is prevented from sliding, and the cutting tool can be well prevented from sliding under large torsion.
Description
Technical field
The utility model relates to drilling machine, threading apparatus accessory technical field, relates in particular to be a kind ofly used for preventing that for holing, on threading apparatus the collet chuck structure skidding from appearring in cutter while rotation.
Background technology
Collet chuck be widely used in lathe and other plant equipment, in order to connect the fastening means between handle of a knife and cutter.ER collet chuck is the one of collet chuck, is manufactured by the invention of REGO-FI X company of Switzerland, is widely used in now all kinds of machining clampings field, mainly in boring, and milling, fraising, is used in tapping and grinding.Its clamp precision is high, and clamping and replacing are convenient, but current structure has a shortcoming, runs into torsion larger, and particularly screw tap, can produce the problem that chucking power is inadequate, easily makes screw tap skid.
Utility model content
The purpose of this utility model is the defect for above-mentioned prior art, provides a kind of and is used for preventing for holing, on threading apparatus the collet chuck structure that cutter skids, and in the time of the situation of larger torsion, still can prevent that skidding from appearring in cutter while rotation.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of collet chuck structure that prevents that cutter from skidding, comprise rotating shaft, ER collet chuck, the cutter of device in ER collet chuck, described rotating shaft is provided with the internal taper hole suitable with the external taper of ER collet chuck, described ER collet chuck clamping is in the internal taper hole of rotating shaft, and the afterbody of described cutter stretches out and extends to the internal taper hole of rotating shaft from ER collet chuck; The front portion of described rotating shaft is provided with external screw thread, described ER collet chuck front end is provided with ER nut, described ER nut and rotating shaft are threaded connection, cutter in ER collet chuck and ER collet chuck is clamped, the two side of described rotating shaft is arranging two screws with respect to the position of cutter afterbody in extending to internal taper hole, in two described screws, screw in screw, hold out against two planes of cutter afterbody.
Compared with prior art, the beneficial effects of the utility model are:
The collet chuck structure that prevents that cutter from skidding of the present utility model, the clamping of ER collet chuck has cutter, ER collet chuck and cutter holding, in the internal taper hole of rotating shaft, anterior compress by ER nut, pressure tighter, ER collet chuck is larger to the chucking power of cutter, the possibility that cutter skids is less, and rotating shaft lateral wall, at the screw that is provided with respect to cutter afterbody, is inside provided with screw, two screws can hold out against two planes of cutter afterbody, can better prevent that cutter from skidding.In the time there is the situation of larger torsion, still can prevent that skidding from appearring in cutter while rotation.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation that prevents the collet chuck structure that cutter skids of the present utility model;
In figure: 1, rotating shaft; 2, screw; 3, screw; 4, ER collet chuck; 5, ER nut; 6, cutter.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only 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 obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the collet chuck structure that prevents that cutter from skidding of the present utility model, comprise rotating shaft 1, ER collet chuck 4, the cutter 6 of device in ER collet chuck 4, described rotating shaft 1 is provided with the internal taper hole suitable with the external taper of ER collet chuck 4, described ER collet chuck 4 clampings are in the internal taper hole of rotating shaft 1, and the afterbody of described cutter 6 stretches out and extends to the internal taper hole of rotating shaft 1 from ER collet chuck 4; The front portion of described rotating shaft 1 is provided with external screw thread, described ER collet chuck 4 front ends are provided with ER nut 5, described ER nut 5 is threaded connection with rotating shaft 1, cutter 6 in ER collet chuck 4 and ER collet chuck 4 is clamped, the two side of described rotating shaft 1 is arranging two screws 2 with respect to the position of 6 afterbodys of cutter in extending to internal taper hole, in described two screws 2, screw in screw 3, hold out against two planes of cutter 6 afterbodys.
