Description

Technical Field

[0001] The utility model belongs to the field of tool holders, and particularly relates to an inner diameter hole tool holder for quickly positioning a tool. Background Art

[0002] The numerical control lathe tool holder belongs to the field of metal processing tools. Numerical control tools are rarely directly installed on the tool rest of a numerical control lathe. They generally use a tool holder as a transition. The inner diameter hole tool holder is a common type of tool holder. When installing a tool, the tool needs to be inserted into the tool installation hole, and a fastening bolt is passed through both to complete the locking. Before this, the holes on the tool and the tool holder often need to be aligned before the fastening bolt can be screwed through. This operation requires multiple calibrations and positioning, which is time-consuming. Summary of the Invention

[0003] The purpose of the utility model is to provide an inner diameter hole tool holder for quickly positioning a tool in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: an inner diameter hole tool holder for quickly positioning a tool, including a tool holder body and a tool installation hole for installing a tool, characterized in that a plurality of bolt holes are opened on the tool installation hole, every two of the bolt holes are symmetrically arranged in a group, a slidable sliding ring is arranged on one side of the bolt holes, one end of the sliding ring is provided with a plurality of support rods for supporting and connecting, one end of the support rod extends into the bolt hole, and a limiting part for limiting is arranged at the junction thereof, and the other end of the sliding ring is provided with a plurality of positioning buckles for positioning.

[0005] In the above-mentioned inner diameter hole tool holder for quickly positioning a tool, a channel for sliding the positioning buckle is opened on the outer ring of the bolt hole.

[0006] In the above-mentioned inner diameter hole tool holder for quickly positioning a tool, an elastic element with an elastic reset function is arranged on the support rod.

[0007] In the above-mentioned inner diameter hole tool holder for quickly positioning a tool, the support rods and the positioning buckles are arranged in an annular equidistant manner, and the positioning buckles and the support rods are on the same horizontal line.

[0008] In the above-mentioned inner diameter hole tool holder for quickly positioning a tool, the positioning buckle inclines outward from the center of the sliding ring to form a slope for cooperating with the tool.

[0009] Compared with the prior art, the inner diameter hole tool holder for quickly positioning a tool quickly positions the hole on the tool through the positioning buckle, reducing the calibration time during installation. Description of the Drawings

[0014] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0015] As Figure 1 , Figure 2 , Figure 3 shown, the inner diameter hole tool holder of this quick positioning tool includes the tool holder body 1 and the tool mounting hole 2 for installing the tool. A number of bolt holes 3 are provided on the tool mounting hole 2. Every two bolt holes 3 are symmetrically arranged in a group. A slidable sliding ring 4 is provided on one side of the bolt holes 3. A number of support rods 5 for supporting and connecting are provided at one end of the sliding ring 4. One end of the support rod 5 extends into the bolt hole 3, and a limiting part 6 for limiting is provided at their junction. A number of positioning buckles 7 for positioning are provided at the other end of the sliding ring 4.

[0016] Further elaborating, a channel 8 for the sliding of the positioning buckle 7 is provided on the outer circle of the bolt hole 3.

[0017] Further elaborating, an elastic element 9 with an elastic reset function is provided on the support rod 5.

[0018] Further elaborating, the support rods 5 and the positioning buckles 7 are arranged in an annular equidistant manner, and the positioning buckles 7 and the support rods are on the same horizontal line.

[0019] Further elaborating, the positioning buckle 7 inclines outward from the center of the sliding ring 4 to form a slope 10 for cooperating with the tool.

[0020] During the installation process, the tool is inserted into the tool mounting hole 2. After the tool contacts the positioning buckle 7, through the slope 10, the positioning buckle 7 is pushed. The positioning buckle 7 drives the support rod 5 to move into the threaded hole, and continues to push the tool. When the positioning buckle 7 contacts the hole on the tool, the positioning buckle 7 is reset by the elastic element 9, so that the tip of the slope 10 enters the hole on the tool to complete the positioning. Then, the fastening bolt is screwed and locked to complete the installation;

[0021] When disassembling, loosen and pull out the fastening bolts, and pull out the cutting tool outward. When the edge of the hole on the cutting tool passes through the ramp 10 and pushes the positioning buckle 7, the cutting tool can be pulled out.

[0022] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0023] Although terms such as tool holder body 1, tool mounting hole 2, bolt hole 3, sliding ring 4, support rod 5, limiting portion 6, positioning buckle 7, channel 8, elastic element 9, ramp 10, etc. are used more frequently in this article, the possibility of using other terms is not excluded. Using these terms is only for more conveniently describing and explaining the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
