Description

[Technical field]

[0001] The utility model relates to the technical field of clamps, in particular to a quick clamp for processing a tapered hole. [Background technology]

[0002] The main problem of processing the taper hole of pipe fittings is the fixture fixing problem. The traditional pipe fitting processing is directly clamped on the machine tool, which easily causes the pipe fitting to be unstable and even deformed, which greatly reduces the processing accuracy of the pipe fitting. The utility model designs a quick fixture for processing the taper hole, which can better protect the pipe fitting and make the processing accuracy of the pipe fitting higher under the action of the fixture. [Contents of the utility model]

[0003] The purpose of the utility model is to solve the problems in the prior art and to provide a quick clamp for processing a tapered hole, which can solve the problem of fixing when processing a tapered hole of a tubular material.

[0004] To achieve the above-mentioned purpose, the utility model proposes a quick clamp for tapered hole processing, including a cylindrical main body, a cylindrical first through hole is arranged at the center of the main body, a plurality of rectangular second through holes distributed in a ring shape are arranged on the main body, the second through holes are perpendicular to the side of the first through hole, the first through hole and the second through hole are connected, and a through groove is also arranged on the main body, and the through groove is connected to one of the second through holes.

[0005] Preferably, a cylindrical third through hole is further provided on the main body, the third through hole is provided corresponding to the second through hole, the second through hole is located between the first through hole and the third through hole, and the first through hole and the third through hole are connected through the second through hole.

[0006] Preferably, an internal thread is provided on the inner side wall of the first through hole.

[0007] Preferably, the inner thread surface is provided with an elastic anti-slip coating.

[0008] Beneficial effects of the utility model:

[0009] 1. Providing a through groove connected to the second through hole can reduce the stress generated by the external force of the machine tool when the fixture is installed on the machine tool, so that the fixture can clamp the processed pipe fitting.

[0010] Second, the third through hole is provided so that after the clamp is deformed under the action of external force, the pipe fitting clamped by the clamp is subjected to uniform force around the periphery without deformation, thereby improving the precision.

[0011] 3. An internal thread is arranged on the inner wall of the first through hole, which facilitates the processing of pipe fittings with external threads. The external thread of the pipe fittings will not be damaged when the clamp is clamped, and the pipe fittings can be fixed more firmly.

[0012] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.

[0016] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings. [Specific implementation method]

[0017] Embodiment 1:

[0018] The utility model comprises a cylindrical main body 1, a cylindrical first through hole 2 is arranged at the center of the main body 1, a plurality of rectangular second through holes 4 distributed in a ring shape are arranged on the main body 1, the second through holes 4 are perpendicular to the side of the first through holes 2, the first through holes 2 and the second through holes 4 are in a connected state, a through groove 6 is also arranged on the main body 1, the through groove 6 is connected with one of the second through holes 4, and the through groove 6 is arranged to connect the second through holes 4 to reduce the stress generated by the external force of the machine tool when the fixture is installed on the machine tool.

[0019] Advantageously, a cylindrical third through hole 3 is further provided on the main body 1, and the third through hole 3 is provided corresponding to the second through hole 4, the second through hole 4 is located between the first through hole 2 and the third through hole 3, and the first through hole 2 and the third through hole 3 are connected through the second through hole 4. When the clamp is mounted on a machine tool, the machine tool will exert an external force on the clamp, at which time the main body 1 contracts, the through groove 6 becomes smaller, the first through hole 2 becomes smaller, and the pipe fitting in the first through hole 2 is clamped and fixed, and the third through hole 3 provided can make the pressure on the inner wall of the first through hole 2 applied to the pipe fitting uniform, so that the pipe fitting is fixed more firmly by the clamp.

[0020] Advantageously, an internal thread 5 is provided on the inner side wall of the first through hole 2, so that when processing a pipe fitting with an external thread, the external thread of the pipe fitting is not damaged when clamped by a clamp, and the pipe fitting can be fixed more firmly.

[0021] Advantageously, the surface of the internal thread 5 is provided with an elastic anti-slip coating, and the elastic coating can prevent the pipe with the external thread from directly contacting the metal surface of the clamp when clamping, thereby protecting the pipe.

[0022] Working principle of this utility model:

[0023] First, clamp the pipe to be processed into the first through hole 2 of the fixture, and then install the entire fixture on the machine tool. When the machine tool is started, the fixture will automatically clamp the fixture. The fixture is compressed inward by the external force of the machine tool. At this time, the through groove 6 becomes downward, and all the second through holes 4 are also compressed. The second through holes 4 drive the third through holes 3 to become smaller. At this time, the first through hole 2 becomes smaller, and the inner wall of the first through hole 2 gives the pipe fitting an extrusion pressure, so that the pipe fitting is firmly fixed in the middle of the fixture.

[0024] If the pipe fitting has external threads, it is necessary to select a fixture with internal threads 5 inside the first through hole 2, screw the pipe fitting with external threads into the first through hole through thread matching, and then install it on the machine tool.

[0025] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
