All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 shows a claw 1 according to an embodiment of the present invention, which includes a base 105, a first clamping member 102 and a second clamping member 103, where the first clamping member 102 and the second clamping member 103 are disposed on the base 105 at intervals, and a height of the first clamping member 102 and/or the second clamping member 103 extending out of the base 105 is adjustable, so that a height of the first clamping member 102 extending out of the base 105 is higher than a height of the second clamping member 103 extending out of the base 105, or a height of the first clamping member 102 extending out of the base 105 is lower than a height of the second clamping member 103 extending out of the base 105.
The clamping jaw 1 can be used as an independent accessory to be mounted on various clamps, such as clamping jaws used as chuck clamps. Referring to fig. 1, when the above-mentioned jaws 1 are applied to a chuck fixture, the bases 105 of the jaws 1 are arranged along the radial direction of the chuck fixture such that the first and second clamping members 102 and 103 are arranged at intervals along the radial direction of the chuck fixture; the chuck fixture shown in fig. 1 has two working states, please refer to fig. 2, which is a first working state of the chuck fixture, at this time, the first clamping member 102 extends out of the base 105 to a higher level than the second clamping member 103 extends out of the base 105, the first clamping member 102 is used as a clamping portion, and the workpiece can be clamped by the inner side wall or the outer side wall of the first clamping member 102, and fig. 2 shows a process of clamping the inner wall of the workpiece by the outer side wall of the first clamping member 102. Referring to fig. 3, fig. 3 is a second working state of the chuck fixture, where the height of the first clamping member 102 extending out of the base 105 is lower than the height of the second clamping member 103 extending out of the base 105, the second clamping member 103 is used as a clamping portion, and the workpiece can be clamped by the inner side wall or the outer side wall of the second clamping member 103, and fig. 3 shows a process of clamping the inner wall of the workpiece by the inner side wall of the second clamping member 103. Therefore, the same clamping jaw 1 can clamp workpieces with different shapes or different parts of the same workpiece, and the frequency of replacing the clamp in the workpiece machining process is effectively reduced.
Wherein, in order to realize the adjustment of the relative height between the first clamping member 102 and the second clamping member 103, the first clamping member 102 may be fixedly connected with respect to the base 105, and the second clamping member 103 may be movably connected with the base 105, and the adjustment of the relative height between the first clamping member 102 and the second clamping member 103 may be realized by adjusting the protruding height of the second clamping member 103 with respect to the base 105. It is also possible to fixedly connect the second clamping member 103 with respect to the base 105 and to movably connect the first clamping member 102 with the base 105, and to adjust the relative height between the first clamping member 102 and the second clamping member 103 by adjusting the protruding height of the first clamping member 102 with respect to the base 105. It is also possible to movably connect the first clamping member 102 and the second clamping member 103 to the base 105, respectively, so that the adjustment of the relative height between the first clamping member 102 and the second clamping member 103 can be achieved by synchronously adjusting the heights of the first clamping member 102 and the second clamping member 103 extending out of the base 105. In addition, the first clamping member 102 and the second clamping member 103 may be detachably connected to the base 105, respectively, and when one clamping member is required to be used, the other clamping member may be detached.
It should be understood that the number of clamping members of the jaws 1 may be greater than two, wherein each clamping member may be detachably connected to the base 105, so that when the clamping position of the workpiece needs to be changed, only a different clamping member needs to be replaced, and at this time, the number of clamping action portions of each jaw 1 may be more than two, that is, each jaw 1 may adapt to clamping of at least three workpieces with different shapes, thereby further reducing the frequency of replacing the clamp during workpiece processing.
Specifically, in the process of clamping a workpiece by the claw 1, when the first clamping member 102 protrudes from the base 105 to a height higher than the height of the second clamping member 103 protruding from the base 105, the first clamping member 102 serves as a clamping action portion; when the first clamping member 102 extends out of the base 105 to a lower level than the second clamping member 103 extends out of the base 105, the second clamping member 103 serves as a clamping portion, and due to the fact that the clamping positions of the first clamping member 102 and the second clamping member 103 are different, workpieces of different shapes or sizes can be clamped by adjusting the relative heights of the first clamping member 102 and the second clamping member 103, and therefore the problem that in the prior art, the same workpiece needs to be machined, clamps need to be replaced frequently, and machining efficiency is low is solved.
