Abstract
A clamping jaw for claming workpiece or cutting tool is composed of a basic jaw with triangular teeth whose tooth top has both truncated sides to become trapezoidal side teeth and the screw hole at the position of triangular teeth, and a high jaw with triangular teeth and trapezoidal tooth spaces for matching with the trapezoidal side teeth of basic jaw, transverse locating slot on the tooth and waist hole.
Description
Technical field
The present invention relates to the clamping device of Machinetool workpiece or cutter, specifically relate to the claw of a kind of clamping work pieces or cutter.
Background technology
The claw stroke of the power chuck of Digit Control Machine Tool is little, in order to enlarge its clamping diameter range, the normal disengaging pawl that adopts, be basic pawl and high pawl, broach radial location between base pawl and the high pawl, T type slot bolt located lateral also connects basic high pawl, regulates the radial position of T-slot bolt and can regulate high pawl radial position.But because the bolt head of T type slot bolt is positioned at the radial slot of basic pawl, wait in the chuck hermetically sealed, high pawl radial position can not be regulated on a large scale, has limited the clamping diameter range.
DE10045257 proposes to utilize cross one another helical teeth to realize the radial location and the located lateral of basic pawl and high pawl simultaneously, and the bolt head of connecting bolt is positioned on the high pawl.But because helical teeth spreads all over the whole joint face of basic high pawl, add man-hour, the cutting output of helical teeth is big, and very strong impact is arranged; Simultaneously, cross one another helical teeth will obtain high dimension precision, and difficulty of processing is very big.
Summary of the invention
Therefore the objective of the invention is to propose the claw of a kind of clamping work pieces or cutter, can not only realize between basic pawl, high pawl radially and located lateral, and be easy to processing.
The technical solution adopted for the present invention to solve the technical problems is: comprise that basic pawl that has tooth and the high pawl that has tooth match, and connect as one with screw.The base pawl simultaneously has the basic pawl lance tooth of equidistant arrangement, the tooth top of base pawl lance tooth both sides scabbles into basic pawl stepped tooth, have basic pawl screw hole on the basic pawl lance tooth in the middle of the base pawl, it is triangle that high pawl simultaneously has the equidistant tooth top of arranging of identical tooth pitch with basic pawl, teeth groove is trapezoidal high blade tooth, high pawl has the one side centre of tooth to have high pawl located lateral groove, have the high pawl mounting hole parallel in the middle of the high pawl with high pawl located lateral groove, basic pawl lance tooth two sides in the middle of the base pawl cooperate with high pawl located lateral groove, and the basic pawl stepped tooth on basic pawl both sides cooperates with high blade tooth.
The beneficial effect that the present invention has is: the teeth groove of basic pawl and high pawl can be realized the radial location and the located lateral of basic pawl and high pawl simultaneously, and is simple in structure; The tooth of base pawl and high pawl is easy to processing, easily obtains high dimension precision; In the middle of the high pawl is locating slot, and the working (finishing) area of tooth is little.

Among the figure: 1,1 '. basic pawl, 2,2 '. high pawl, 3. screw, 4. basic pawl stepped tooth, 5. chuck, 6. basic pawl lance tooth, 7. high blade tooth, 8,8 '. high pawl mounting hole, 9. high pawl located lateral groove, 10,10 '. basic pawl screw hole, 4 '. high pawl stepped tooth, 6 '. high pawl lance tooth, 7 '. basic blade tooth, 9 '. basic pawl located lateral groove.
The specific embodiment
By the invention will be further described by drawings and Examples.
Shown in Fig. 1～9, the present invention includes basic pawl 1 that has tooth and the high pawl 2 that has tooth and match, and connect as one with screw 3.Base pawl 1 one side has the basic pawl lance tooth 6 of equidistant arrangement, the tooth top of base pawl lance tooth 6 both sides scabbles into basic pawl stepped tooth 4, have basic pawl screw hole 10 on the basic pawl lance tooth 6 in the middle of the base pawl 1, it is triangle that high pawl 2 one sides have with the equidistant tooth top of arranging of basic pawl 1 identical tooth pitch, teeth groove is trapezoidal high blade tooth 7, high pawl 2 has the one side centre of tooth to have high pawl located lateral groove 9, have the high pawl mounting hole 8 parallel in the middle of the high pawl 2 with high pawl located lateral groove 9, basic pawl lance tooth 6 two sides in the middle of the base pawl 1 cooperate with high pawl located lateral groove 9, and the basic pawl stepped tooth 4 on basic pawl 1 both sides cooperates with high blade tooth 7.
As shown in Figure 1, claw is installed in the chuck 5, the radial motion under the driving of chuck drive mechanism of basic pawl 1, and drive high pawl 2 and move together, clamp, unclamp workpiece or cutter.As shown in Figure 9, the two sides of the basic pawl lance tooth 6 of basic pawl 1 cooperate with high pawl located lateral groove 9, realize the located lateral of high pawl 2.The basic pawl stepped tooth 4 on base pawl 1 both sides cooperates with high pawl 2 teeth, realizes the radial location of high pawl.When regulating high pawl 2 radial positions, unclamp screw 3, according to the workpiece or the tool diameter needs of clamping, the one or more tooth pitches of high pawl 2 radiai adjustment, trip bolt 3 again, can finish the radiai adjustment of high pawl 2.When changing high pawl 2, take screw 3 apart, unload high pawl 2, change new high pawl 2, trip bolt 3 again, can finish the replacing of high pawl 2.
Figure 10 is the another kind of form of implementation of claw of the present invention, high pawl 2 ' one side has the high pawl lance tooth 6 ' of equidistant arrangement, the tooth top of high pawl lance tooth 6 ' both sides scabbles into high pawl stepped tooth 4 ', have high pawl mounting hole 8 ' in the middle of the high pawl 2 ', it is that triangle, teeth groove are trapezoidal basic blade tooth 7 ' that base pawl 1 ' one side has with the equidistant tooth top of arranging of high pawl 2 ' identical tooth pitch, base pawl 1 ' has the one side centre of tooth to have basic pawl located lateral groove 9 ', has basic pawl screw hole 10 ' in the middle of the basic pawl 1 '.
Fig. 1 is to be example with the scroll chuck, in fact can be applicable in the multijaw chucks such as two pawls, four paws.The present invention not only can be applicable on the soft high pawl, also can be applicable in the hard high pawl.
