Detailed Description
The following describes a specific embodiment of the present embodiment with reference to the drawings.
Fig. 1 is an assembly diagram of the present invention. Fig. 2 is a side view of the present invention. Fig. 3 is a schematic structural diagram of the present invention. With reference to fig. 1, 2 and 3, the present invention discloses a tensioning clamp for machining annular parts. The tensioning clamp is mounted around a machine tool chuck, and an annular part is mounted outside the tensioning clamp. The tensioning clamp for machining the annular part comprises a moving block 1 and a tensioning disc 2.
The moving block 1 is mounted on a machine tool chuck. The tension disc 2 is fixedly mounted on the moving block 1. The machine tool chuck drives the moving block 1 to move. The moving block 1 drives the tensioning disc 2 to approach or depart from the annular part.
Preferably, the machine tool chuck is a three-jaw chuck. A tensioning clamp for annular part machining is mounted on a machine tool chuck. Preferably, the number of the tensioning clamps for machining the annular part is three.
The machine tool chuck is a three-jaw chuck, and the selection of the type of the three-jaw chuck belongs to the common knowledge. Those skilled in the art can select the type of chuck, e.g., K11-315, according to the operation of the device.
One end of the moving block 1 close to the machine tool chuck is provided with a moving boss 3 in parallel. Preferably, the moving boss 3 is circular arc-shaped.
One end of the moving block 1 close to the machine tool chuck is arranged on the chuck. The moving boss 3 is provided on the lower surface of the moving block 1. The moving bosses 3 are arranged on the lower surface of the moving block 1 in parallel from outside to inside.
The moving block 1 needs to be mounted on the wire of the machine tool chuck. The spiral groove is arranged on the spiral wire. When the moving block 1 is arranged on a machine tool chuck, the moving boss 3 is embedded into the spiral groove. The machine tool chuck drives the moving block 1 to move inwards or outwards.
The moving block 1 is symmetrically provided with moving grooves 4.
Preferably, the moving slot 4 is a through slot. The moving grooves 4 are opened on both right and left sides of the moving block 1. When the moving block 1 is installed on a machine tool chuck, the moving groove 4 is installed in a matching way with the machine tool chuck. When the machine tool chuck drives the moving block 1 to move inwards or outwards, the moving groove 4 can ensure that the moving block 1 can move stably.
One end of the moving block 1 close to the tensioning disc 2 is provided with a supporting rib 6, and the supporting rib 6 supports the tensioning disc 2.
The upper end of the moving block 1 is provided with a tension disc 2. The supporting rib 6 is arranged at the upper end of the moving block 1. The supporting ribs 6 are symmetrically arranged at the left side and the right side of the upper end of the moving block 1. The lower end of the supporting rib 6 is connected with the upper end of the moving block 1. The upper end of the supporting rib 6 is connected with the lower end of the tensioning disc 2.
Preferably, the tension disc 2 is sector-shaped. The sector angle of the tensioning disc 2 is 120 °. The tension disc 2 is sector-shaped extending from the inside to the outside.
A boss 5 is arranged at one end of the tension disc 2 close to the annular part. Preferably, the boss 5 is circular arc-shaped. The outer end of the tension disc 2 is provided with a boss 5. The inner end of the boss 5 is connected with the outer end of the tension disc 2. The boss 5 increases the contact area with the ring-shaped member so that the ring-shaped member can be supported better. The tensioning disc 2 provides a supporting force for the boss 5 so that the boss 5 can support the annular part outwards. The circular arc-shaped boss 5 avoids damage to the annular part in the process of outward supporting.
When the tensioning clamp for machining the annular part is used for installing a workpiece, the tensioning disc 2 penetrates through the inner ring of the annular part. The tension disc 2 and the boss 5 are located within the inner ring of the annular part.
The machine tool chuck drives the moving block 1 to move outwards, and the moving block 1 drives the tensioning disc 2 to move outwards. The tension disc 2 is close to the inner ring of the annular part and the boss 5 contacts the inner ring of the annular part.
The machine tool chuck drives the moving block 1 to move inwards, and the moving block 1 drives the tensioning disc 2 to move inwards. The tension disc 2 is far away from the inner ring of the annular part and the boss 5 is no longer in contact with the inner ring of the annular part.
The traditional chuck clamps the annular part from the outer end of the annular part, and only the annular part with the diameter smaller than that of the chuck of the machine tool can be clamped due to the structural limitation of the chuck of the machine tool. The tensioning clamp for machining the annular part can be suitable for annular parts with different sizes. The tensioning clamp for annular part machining is supported outwards from the inner ring of the annular part, and can clamp the annular part with the diameter larger than that of a chuck of a machine tool.
The tensioning clamp for annular part machining can also be applied to machining of pipelines, and the tensioning clamp for annular part machining supports the pipelines outwards from the inside of the pipelines so as to finish clamping the pipelines.
In the present embodiment, the machine tool chuck described is a three-jaw chuck, but the chuck is not limited to this, and may be a chuck having another number of jaws within a range in which the chuck can function.
In the present specification, terms such as "circular arc" and "fan" are used, and these terms are not exactly "circular arc" and "fan", and may be in the form of "substantially circular arc" and "substantially fan" within a range in which the functions thereof can be exhibited.
In the present specification, the number of "three" or the like is used, but the present invention is not limited thereto, and other numbers may be used within a range where the functions thereof can be exerted.
The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
