Abstract
The utility model discloses a knife handle collet locking device and belongs to the field of metal machine tool part devices. An existing tool has the defects of poor interchangeability, expensive cost and the like. The knife handle collet locking device comprises a knife handle body, a worm gear mechanism and a collet, wherein a central shaft hole is formed in the body, the collet is the cone-shaped collet, the central shaft hole is formed to be a cone-shaped cavity at the head portion of the knife handle body, the collet is installed in the cone-shaped cavity, the worm gear mechanism is arranged in the center of the central shaft hole, and a worm gear is connected with the tail end of the collet through threads in a matched and transmitting mode. The knife handle collet locking device has the advantages of being capable of achieving accurately and reliably clamping and fixing the tool, simple and compact in structure, relatively easy to manufacture and relatively low in cost.
Description
Technical field
The utility model belongs to metal machine tool element device field, relates to the handle of a knife collet chuck locking device on a kind of lathe.
Background technology
Conventional tool is fixedly installed on collet chuck, and collet chuck is fixed on handle of a knife, when needs are changed cutter, first handle of a knife is disassembled from lathe, and then cutter is taken off the replacing cutter from handle of a knife, need a large amount of manpowers to complete, operate very complicatedly, and greatly reduce operating efficiency.
The utility model content
The defectives such as the purpose of this utility model will overcome exactly existing collet chuck and exist dismounting inconvenient, and cost is large provide a kind of easy accessibility, handle of a knife collet chuck locking device that clamp precision is high.
For this reason, the utility model is by the following technical solutions: a kind of handle of a knife collet chuck locking device, comprise handle of a knife body and collet chuck, the handle of a knife body is provided with central shaft hole, collet chuck is fixedly installed in central shaft hole, it is characterized in that, described handle of a knife collet chuck locking device also comprises worm-and-wheel gear, described collet chuck is a tapered collet, the head center axis hole of handle of a knife body is made as conical cavity, collet chuck is installed in conical cavity, and described worm-and-wheel gear is arranged at the middle part of central shaft hole, and worm gear coordinates with the tail end of collet chuck by screw thread and is in transmission connection.
As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.
Be provided with one section dead slot between described worm gear and body, dead slot is provided with locating shaft, and locating shaft does not contact with worm gear, makes worm gear motion limited distance on the axis direction of collet chuck, avoids worm gear and worm screw to break away from.
Use the utility model can reach following beneficial effect: the utility model is when installing or change cutter, use the spanner rotary worm, worm gear in cavity can rotate accordingly, thereby side-to-side movement on the axis direction of the collet chuck of drive tapered collet, reach locking or the purpose of unclamping collet chuck, cutter just can be changed easily, can be accurately, reliably cutter is gripped, simple and compact for structure, making is comparatively easy and cost is lower.
