Abstract
The utility model discloses a tap chuck comprising a holding body (1) and a clamping body (2) which are in sleeve joint by screw threads, wherein the front section of the clamping body (2) and the front section of the holding body (1) are both provided with a conical surface (a) with the same taper. The tap chuck is characterized in that four through holes (4) with equal aperture, which are separated in an evenly divided way, are arranged on the same circumference of the front section of the holding body (1), which is close to the end head, and a steel ball (5) is respectively arranged in each hole; and 2 to 4 threaded through holes vertical to the axis are arranged on the pipe wall (b) of the straight section of the clamping body (2) at intervals, and a locking screw (3) is installed in each threaded through hole. When the utility model is used for clamping a tap, the position of a square tenon of a handle part of the tap is clamped, which has simple structure, can adapt to the clamping of taps with various specifications and has stable and reliable clamping force. Even if vibratory tapping is carried out, the tap also can not slip or fall off, and the assembly and the disassembly of the tap are also very convenient.
Description
Technical field
The utility model belongs to machine tool accessories, and what relate to is a kind of anchor clamps, is specifically related to a kind of tap chuck that is used for tapping.
Background technology
At present, tap chuck commonly used during the lathe tapping has common drill chuck and collet, the cramping body front end of tap chuck is clamped the tap holder bar with the extruding form under the effect that keeps body, fixedly connected with the processing rotating shaft of lathe with clamping device by the centering head in the rear end of cramping body, screw tap carries out tapping to workpiece under the drive of processing rotating shaft.In tapping process, existing common drill chuck can't be adjusted the clamping force of screw tap, and screw tap can become flexible because of vibrations, therefore, screw tap takes place often skid on chuck, even the phenomenon that screw tap comes off takes place.Although but the clamping force of collet elasticity in tapping process changes, overcome the influence of vibrations, the vary in diameter scope of collet is little, and a collet only adapts to several diameters and differs very little screw tap, and the screw tap of different size needs many sleeve springs chuck to come clamping.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective of the prior art, provides a kind of clamping firm and can adapt to the tap chuck of plurality of specifications screw tap.
The technical scheme that realizes above-mentioned purpose is: a kind of tap chuck, comprise and keep body and cramping body, the back segment thread bush of cramping body is connected in the outer wall posterior segment that keeps body, the leading portion of cramping body and the leading portion that keeps body all have the taper seat of identical tapering, keeping the inner chamber of body is hollow axocoel, it is characterized in that, the leading portion of described maintenance body is near five equilibrium four equal aperture through holes are at interval arranged on the same circumference of termination, a steel ball respectively is housed in each hole, aperture and steel ball size equate, and greater than the degree of depth in hole; On described cramping body straight section tube wall, be arranged at intervals with 2-4 tapped through hole, a lock-screw is installed in each tapped through hole perpendicular to axis.
When above-mentioned tapped through hole was set to two, its position was at the two ends of same radial line.
When above-mentioned tapped through hole was set to three, its position was on same circumference, and angle is 120 degree at interval.
When above-mentioned tapped through hole was set to four, its interval angle was 90 degree.
Be that tenon position, shank side with screw tap is inserted in by in four centre bores that steel ball surrounded during the utility model clamping screw tap, then cramping body screwed with keeping body.In the process of cramping body precession, its front end inner conical surface pushes four steel balls that keep on the body gradually and draws in to central point, strengthens the clamping force to screw tap side's tenon gradually, until it is clamped fully.If vibrating and tapping after screw tap is clamped, tightens lock-screw again, so just can prevent cramping body and keep that body is relative to be rotated, guarantee that screw tap can not become flexible.
The utility model tap chuck is simple in structure, can adapt to the clamping of plurality of specifications screw tap, and its chucking power is stable, reliable, even vibrating and tapping, screw tap can not skid or come off yet, and the screw tap loading and unloading are also very convenient.
Description of drawings
Fig. 1 is the overall structure cutaway view of an embodiment of the utility model.
Fig. 2 be among Fig. 1 A-A to cutaway view.
Among the figure: 1. keep body, 2. cramping body, 3. lock-screw, 4. through hole, 5. steel ball, a. taper seat, b. straight section tube wall, c. screw thread, d. conical cavity.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1-2, the main body of the utility model tap chuck has the body 1 of maintenance and 2 two parts of cramping body, and the back segment inwall of cramping body 2 has internal thread, keeps the outer wall posterior segment of body 1 that external screw thread is arranged, and both screw thread c interlock; The leading portion of cramping body 2 and the leading portion that keeps body 1 all have the taper seat a of identical tapering; The stage casing of the stage casing of cramping body 2 and maintenance body 1 is straight section tube wall b, and both are slidingly matched.Keeping the inner chamber of body 1 is hollow axocoel, and the back segment of axocoel is the little conical cavity d of outer imperial palace, and conical cavity d is the processing rotating shaft fixed connecting part of chuck and lathe.The leading portion that keeps body 1 respectively is equipped with a steel ball 5 near five equilibrium four equal aperture through holes 4 are at interval arranged on the same circumference of termination in each hole, aperture and steel ball size equate, and greater than the degree of depth in hole; On cramping body 2 straight section tube walls, be arranged at intervals with four tapped through holes, a lock-screw 3 is installed in each tapped through hole perpendicular to axis.
The number of the tapped through hole that is provided with at interval on the above-mentioned cramping body 2 straight section tube walls also can be two or three except that described four of present embodiment.
