Abstract
The utility model discloses a kind of length-adjustable boring cutter frock, comprise the tool rest cover being provided with guide hole, guide pin bushing is provided with in described guide hole, the end of described guide pin bushing is provided with the cavity matched with described tool rest cover, in described guide pin bushing, knife bar is installed, screw rod is provided with in described cavity, one end of described screw rod is connected with described guide pin bushing, the centre position of described screw rod is provided with the first commutation star-wheel, what described tool rest was arranged with that the star-wheel that to commutate with described first matches second to commutate star-wheel, described second commutation star-wheel be located at the drive screw that described tool rest puts and be connected.The driving force of outside can be converted to the movement of internal workpiece by boring cutter frock of the present utility model, realizes the controlled and adjustable of boring cutter length.
Description
Technical field
The utility model relates to lathe part manufacture field, especially relates to a kind of length-adjustable boring cutter frock.
Background technology
In mechanical processing industry, added to the hole of parts man-hour, usually needing to adopt the cutter head of different size to carry out heavy boring, right boring respectively to hole.Different processing modes, needs to carry out fine setting operation to the length of cutter sometimes, particularly at some under the more high-precision requirement of part demand fulfillment of processing, with regard to usually adopt different cutter heads to part carry out repeatedly and the polishing of different accuracy.Now, the requirement of length can only be met by the cutter head changing different size, both can have influence on the precision of processing on the one hand, change the speed that Tang's cutter head also can have influence on processing on the other hand, reduce operating efficiency.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes a kind of length-adjustable boring cutter frock.
As the first embodiment, the utility model provides a kind of length-adjustable boring cutter frock, comprise the tool rest cover being provided with guide hole, guide pin bushing is provided with in described guide hole, the end of described guide pin bushing is provided with the cavity matched with described tool rest cover, in described guide pin bushing, knife bar is installed, screw rod is provided with in described cavity, one end of described screw rod is connected with described guide pin bushing, the centre position of described screw rod is provided with the first commutation star-wheel, what described tool rest was arranged with that the star-wheel that to commutate with described first matches second to commutate star-wheel, described second commutation star-wheel be located at the drive screw that described tool rest puts and be connected.
On the basis of the first embodiment, as the second embodiment, described second commutation star-wheel is positioned at described cavity, and described drive screw is through the inwall of described tool rest cover.
On the basis of the first embodiment, as the third embodiment, described guide pin bushing is fixedly connected with described screw rod.
The length-adjustable boring cutter frock of one provided by the utility model, by arranging tumbler gear, the adjustment action carried out in boring cutter frock outside is delivered to boring cutter inside, change the movement axially of boring cutter internal workpiece into, thus change the length that boring cutter stretches out, the requirement in order to reach different machining accuracy can be removed from and change man-hour and the operation of cutter head, the efficiency of processing is provided.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
The beneficial effect of the technical problem solved to make the utility model, the technical scheme of employing and generation is clearly understood, is described in further detail the utility model below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
Particularly, as shown in Figure 1, the utility model provides a kind of length-adjustable boring cutter frock, comprise the tool rest cover 1 being provided with guide hole, guide pin bushing 2 is provided with in guide hole, the end of guide pin bushing 2 is provided with overlaps 1 cavity matched 3 with tool rest, knife bar 4 is installed in guide pin bushing 2, screw rod 5 is provided with in cavity 3, one end of screw rod 5 is connected with guide pin bushing 2, the centre position of screw rod 5 is provided with the first commutation star-wheel 6, and what tool rest cover 1 was provided with that the star-wheel 6 that commutate with first matches second to commutate star-wheel 7, second commutate star-wheel 7 be located at the drive screw 8 that tool rest overlaps on 1 and be connected.First commutation star-wheel 6 and the second commutation star-wheel 7 are set, the adjustment action carried out are delivered to boring cutter inside, change the movement axially of boring cutter internal workpiece in boring cutter frock outside, thus change the length that boring cutter stretches out, the efficiency of processing is provided.
Particularly, the second commutation star-wheel 7 is positioned at cavity 3, and drive screw 8 is through the inwall of tool rest cover 1.The rotation of drive screw 8 can be converted into the movement of internal part, without the need to institute's work being consumed on other objects.
Particularly, guide pin bushing 2 is fixedly connected with screw rod 5.Drive guide pin bushing 2 to move by rotating drive screw rod 8, be fixedly connected with and make guide pin bushing 2 can realize advancing and retreating along with the different rotary direction of drive screw 8.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace or improvement etc., all should be included within protection domain of the present utility model.
