Description

Technical Field

[0001] The utility model relates to the technical field of fixing tooling, in particular to a TO pipe cap inner support tooling. Background Art

[0002] With the continuous development of big data, cloud computing, mobile Internet, Internet of Things and artificial intelligence technology, the huge data traffic has put forward higher requirements for the capacity and bandwidth of optical fiber communication. In particular, the construction of 5G communication and data centers is in the ascendant, and the global demand for high-performance optical modules is increasing day by day. TO (Transistor Outline), that is, transistors. Most early transistors used coaxial packaging, which was later borrowed into optical communications and called TO packaging, that is, coaxial packaging. TO packaging contains two components: the socket and the cap. TO cap (Transistor Outline CAN), that is, transistor shell, is the international industry standard name for controlling a special conductive electronic shell. It is an important optical coupling device in optical modules. In the field of optoelectronics, TO caps can achieve two basic functions. They provide strong and effective protection for optical components in transmission and reception applications, and as an optical interface (transparent material), they can also ensure the smooth transmission of optical signals.

[0003] TO pipe caps are made of varable materials, and their structural characteristics are thin wall, small axial size, high precision and poor rigidity. The traditional processing method is to clamp the product directly with the lathe fixture. Due to the wide versatility of the lathe fixture, the clamping force of the fixture is too large and the force is uneven. TO pipe cap products are thin-walled parts. The difficulty in processing is that it is easy to cause product deformation during clamping, and the dimensional accuracy is difficult to guarantee, which seriously affects the product qualification rate. Application publication number: CN213410381U, discloses a thin-walled ring-shaped parts processing tooling, provides a thin-walled ring-shaped parts processing tooling that disperses rigid clamping force, reduces shock and absorbs vibration, and can be used for high-precision processing. The inner wall of the thin-walled ring-shaped part is formed with flexible support components evenly distributed on the support tube, and the clamping force of the external rigid claws is dispersed, thereby avoiding the defect of clamping deformation of the workpiece when using a rigid fixture; at the same time, the flexible support structure can reduce and absorb cutting vibration during workpiece cutting, disperse the cutting stress of the workpiece, avoid cutting defects such as burrs, tears, grooves and deformation, and make the processed end face of the workpiece smooth and the thin-wall roundness high, thereby effectively improving the processing accuracy and greatly reducing the defective product ratio of the workpiece.

[0004] When the above-mentioned thin-walled annular component processing tooling is used and adjusted, the three supporting arc plates will have different lengths under the action of the spring, and the supporting strength for the thin-walled annular component will be different, which is easy to cause deviation and uneven force, resulting in product deformation and poor processing accuracy. Utility Model Content

[0005] The purpose of the utility model is to provide a TO tube cap inner support tooling to solve the above shortcomings, and solve the problem of how to clamp the TO tube cap so that it is evenly stressed and not easily deformed, thereby ensuring the dimensional accuracy of the product during processing and improving the product qualification rate. To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A TO pipe cap inner support tooling comprises an inner support column and an inner support bolt; a support column is provided at one end of the inner support column; a through hole is opened in the middle of the support column; the through hole extends into the inner support column; a thread matching with the inner support bolt is provided on the wall of the through hole; a plurality of open slits are evenly provided along the circumferential direction on the support column; one end of the open slit is open to the end of the support column away from the inner support column; when the inner support bolt is screwed into the through hole and matched with the thread, the support column expands to support the TO pipe cap.

[0007] Furthermore, the radius of the support column is smaller than the radius of the inner support column.

[0008] Furthermore, the other end of the opening slit extends into the inner support column.

[0009] Furthermore, an annular reinforcement block is provided on the support column along the circumferential direction.

[0010] Furthermore, a torque wrench is provided on the nut of the inner support bolt.

[0011] Furthermore, the inner support column and the support column are both made of aluminum alloy 7075.

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0021] Embodiment 1:

[0022] Attached Figures 1 to 5 , a TO tube cap internal support tooling, including an internal support column 1 and an internal support bolt 2; a support column 3 is provided at one end of the internal support column 1; a through hole 4 is opened in the middle of the support column 3; the through hole 4 extends into the inner support column 1; a thread that cooperates with the internal support bolt 2 is provided on the wall of the through hole 4; a plurality of opening slits 5 are evenly provided along the circumferential direction on the support column 3; one end of the opening slit 5 is open at the end of the support column 3 away from the internal support column 1; when the internal support bolt 2 is screwed into the through hole 4 and cooperates with the thread, the support column 3 expands to support the TO tube cap. It can be seen from the above structure that the TO tube cap internal support tooling includes an internal support column 1 and an internal support bolt 2, a support column 3 is provided at one end of the internal support column 1, and the radius of the support column 3 is smaller than the radius of the TO tube cap. When the TO tube cap is clamped, the TO tube cap is sleeved on the support column 3. A through hole 4 is provided in the middle of the inner support column 1, and the through hole 4 extends into the inner support column 1, and a thread is provided on the side wall of the through hole 4 in the inner support column 1, and the thread cooperates with the inner support bolt 2. The through hole 4 in the inner support column 1 can be divided into two parts, and the cross section of the through hole 4 in the part away from the inner support column 1 is gradually reduced and connected to the other part of the through hole 4, and the cross section of the other part of the through hole 4 is unchanged and extends into the inner support column 1. A plurality of opening slits 5 are evenly provided along the circumferential direction on the support column 3, and one end of the opening slit 5 opens at the end of the support column 3 away from the inner support column 1 and communicates with the outside, so that the part of the support column 3 provided with the opening slit 5 is divided into a plurality of support blocks by the opening, and when the inner support bolt 2 is screwed into the through hole 4 and cooperates with the thread, the support blocks on the support column 3 open outward and are supported on the inner side wall of the TO cap. The utility model provides a TO tube cap inner support tooling, which makes the TO tube cap evenly stressed and not deformed when clamping it, thus ensuring the stability of the TO tube cap, not affecting the dimensional accuracy when processing the TO tube cap, and improving the qualified rate of the product.

[0023] Embodiment 2:

[0024] See attached Figures 1 to 5 . On the basis of the first embodiment, the radius of the support column 3 is smaller than the radius of the inner support column 1. As can be seen from the above structure, the radius of the support column 3 is smaller than the radius of the inner support column 1, which can strengthen the end structure of the support column 3 in contact with the inner support column 1, help the support column 3 to expand, stabilize the structure of the support column 3 itself, and make it easy to support the support column 3 on the inner wall of the TO tube cap, and the end of the inner support column 1 plays a role of limiting.

[0025] The other end of the opening slit extends into the inner support column 1. As can be seen from the above structure, the other end of the opening slit 5 extends into the inner support column 1, so that when the support column 3 expands under the action of the inner support bolt 2, the structure is not easily damaged. When the inner support bolt 2 is screwed into the inner support column 1 and matched with the thread, the part of the inner support column 1 where the opening slit 5 is provided will expand outward, thereby driving the support column 3 to expand and clamp the inner side wall of the TO cap. In this way, the support column 3 can expand relatively slowly, avoiding product damage when clamping the TO cap.

[0026] Embodiment three:

[0027] See attached Figures 1 to 5 . On the basis of the second embodiment, an annular reinforcement block 6 is provided on the support column 3 along the circumferential direction. As can be seen from the above structure, an annular reinforcement block 6 is provided on the support column 3 along the circumferential direction, and the annular reinforcement block 6 is arranged at the middle and lower part of the inner support column 1, away from the support column 3, and separated from the opening slit 5 by a certain distance. The provision of the annular reinforcement block 6 can improve the strength of the inner support column 1 structure, and is conducive to the inner support tooling being installed on the machine tool, and it is not easy to deform itself.

[0028] The nut of the inner support bolt 2 is equipped with a torque wrench. As can be seen from the above structure, the nut of the inner support bolt 2 is equipped with a torque wrench, which is also called a torque adjustable wrench, that is, the torque can be set, and the torque is adjustable. Using a torque wrench allows the operator to apply a specific torque value, adjust the torque first, and then tighten the bolt. When the TO tube cap needs to be clamped, since the wall of the TO tube cap is very thin, the operator can first set the required torque on the torque wrench, and then tighten the inner support bolt 2 to expand the support column 3, thereby clamping the TO tube cap. In this way, during operation, the support column 3 will not be over-expanded due to excessive screwing of the inner support bolt 2, causing the TO tube cap to deform.

[0029] The inner support column 1 and the support column 3 are made of aluminum alloy 7075. As can be seen from the above structure, the inner support column 1 and the support column 3 are made of aluminum alloy 7075, which is a high-strength heat-treatable alloy with good mechanical properties, practicality, wear resistance, corrosion resistance and oxidation resistance, easy processing and good mechanical properties.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the patent scope of the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
