Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece assembly technology, specifically a pneumatic assembly fixture. Background Technology
[0002] Optical fiber, or optical waveguide fiber, is a thin, filamentary transmission medium made of glass or plastic. Its core principle is to efficiently transmit information using the phenomenon of total internal reflection of light. It possesses significant advantages such as large transmission capacity, low transmission loss, strong resistance to electromagnetic interference, and good security, and is widely used in the field of communications. Optical fiber ends are fitted with fiber optic connectors, and the connectors are externally fitted with UBC (Usage-Based Component) housings.
[0003] In the prior art, patent announcement number CN214770191U discloses a pneumatic pressing machine for fiber optic connectors, including a pressing machine body. A base plate is movably embedded in the lower inner surface of the pressing machine body. A pressure plate is movably installed above the base plate on the inner side of the pressing machine body. An air tank is fixedly installed on the upper surface of the pressing machine body. A compressor is fixedly installed on the upper surface of the air tank. A fixing plate is movably embedded in the upper surface of the base plate. A limit rod is movably embedded near one end of the front surface of the pressing machine body. A control panel is fixedly embedded in the front surface of the pressing machine body. A sliding groove is formed on the lower inner surface of the pressing machine body. A slider is fixedly installed on the lower surface of the base plate. The base plate is movably connected to the pressing machine body through the slider.
[0004] The aforementioned device uses the power provided by a cylinder to press the connector onto the optical fiber. After the connector is pressed onto the optical fiber, the UBC shell needs to be pressed onto the optical fiber connector. During the pressing process of the UBC shell, a slight expansion may occur. This expansion may cause the UBC shell to get stuck at the limiting port. This situation will have a certain impact on the unloading speed. Utility Model Content
[0005] The purpose of this invention is to provide a pneumatic assembly fixture to solve the problems in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic assembly fixture, comprising a device base, a cylinder body fixedly mounted on the device base, a clamping mechanism fixedly mounted on the device base, the clamping mechanism comprising a main support fixedly mounted on the device base, a linear bearing mounted on the main support, a sliding rod slidably mounted inside the linear bearing, a cylinder linkage block fixedly mounted on the sliding rod, and the output end of the cylinder body fixedly mounted on the cylinder linkage block, a pressing top plate fixedly mounted on the cylinder linkage block, a positioning platform fixedly mounted on the upper end of the main support, a limit opening provided on the positioning platform, and a lifting mechanism mounted on the bottom of the positioning platform.
[0007] Preferably, an optical fiber connector is fitted onto the press-fit top plate, and a UBC outer shell is fitted onto the limiting port.
[0008] Preferably, the main support base has mounting holes, and the linear bearing is mounted on the main support base through the mounting holes.
[0009] Preferably, the sliding rod is slidably mounted on the main support base via a linear bearing, the cylinder linkage block is slidably mounted on one side of the main support base via the sliding rod, the pressing top plate is slidably mounted inside the positioning platform via the cylinder linkage block, the bottom of the positioning platform is provided with bolts, and the positioning platform is fixedly mounted on the main support base by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. During the extension of the cylinder body, this application drives the cylinder linkage block to move forward.

[0014] 2. In this application, during the retraction of the cylinder body, it drives the cylinder linkage block to move backward. Subsequently, the linkage rod is driven by the backward movement of the cylinder linkage block, which in turn pulls the wedge block to move backward. The backward movement of the wedge block will cause the lifting block to move upward, which will cause the UBC housing, which is stuck in the limiting port, to be ejected, thereby facilitating the unloading operation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] like Figure 1 and Figure 4 As shown, this utility model provides a technical solution for a pneumatic assembly fixture, including a device base 1, a cylinder body 2 fixedly installed on the device base 1, a clamping mechanism 5 fixedly installed on the device base 1, a lifting mechanism 6 installed at the bottom of the positioning table 505, an optical fiber connector 3 clamped on the pressing top plate 506, and a UBC shell 4 clamped at the limiting port 504. The clamping mechanism 5 can quickly press the UBC shell 4 onto the optical fiber, and the lifting mechanism 6 can push out the UBC shell 4 clamped in the limiting port 504 for easy unloading.
[0019] like Figure 2 and Figure 3 As shown, the clamping mechanism 5 includes a main support base 501 fixedly installed on the equipment base 1. A linear bearing 502 is installed on the main support base 501. A sliding rod 503 is slidably installed inside the linear bearing 502. A cylinder linkage block 507 is fixedly installed on the sliding rod 503. The output end of the cylinder body 2 is fixedly installed on the cylinder linkage block 507. A pressing top plate 506 is fixedly installed on the cylinder linkage block 507. A positioning table 505 is fixedly installed on the upper end of the main support base 501. A limit port 504 is opened on the positioning table 505. An installation hole is opened on the main support base 501. The linear bearing 502 is installed on the main support base 501 through the installation hole.
[0020] Specifically, when the cylinder body 2 extends, this process directly triggers the cylinder linkage block 507 to move forward. Specifically, under the pushing force of the cylinder body 2, the cylinder linkage block 507 begins to move smoothly forward along a preset track or path. Then, as the cylinder linkage block 507 moves forward, the pressing top plate 506, which is closely connected to it, is also driven and begins its forward movement. The forward movement of the pressing top plate 506 causes the fiber optic connector 3 to move forward as well. Finally, the fiber optic connector 3 can be quickly and stably pressed onto the UBC housing 4, thus completing the entire pressing operation.
[0021] like Figure 2 and Figure 4 As shown, the lifting mechanism 6 includes a positioning rod 603 fixedly installed at the bottom of the positioning platform 505 and a linkage rod 601 slidably installed on the main support base 501. A return spring 604 is sleeved on the positioning rod 603. A positioning support foot 607 is slidably installed on the positioning rod 603. A lifting block 602 is fixedly installed on the positioning support foot 607. A pulley 606 is slidably installed at the bottom of the lifting block 602. A wedge block 605 is fixedly installed at one end of the linkage rod 601. The other end of the linkage rod 601 is fixedly installed on the cylinder linkage block 507. An inlet and outlet hole is opened at the bottom of the positioning platform 505. The lifting block 602 extends into the positioning platform 505 through the inlet and outlet hole.
[0022] Specifically, when the cylinder body 2 completes its retraction action, it directly drives the cylinder linkage block 507, which is closely connected to it, to move backward. As the cylinder linkage block 507 gradually moves backward, this action is transmitted to the linkage rod 601, causing the linkage rod 601 to be pulled backward as well. The backward movement of the linkage rod 601 further pulls the wedge block 605, causing it to move backward along a predetermined trajectory. During its backward movement, the wedge block 605 applies an upward pushing force to the lifting block 602, forcing the lifting block 602 to overcome resistance and lift upward. Once the lifting block 602 moves upward, it exerts a force on the UBC housing 4 above it, gradually pushing the UBC housing 4, which was originally stuck in the limiting port 504, out of its restraint. Furthermore, the return spring 604 pushes the lifting block 602 on the positioning foot 607 downward, causing the lifting block 602 to return to its original position.
[0023] Working principle: First, the UBC outer shell 4 is secured within the limiting port 504. Then, the fiber optic connector 3 is placed on the pressing plate 506. Next, the cylinder body 2 can be extended. When the cylinder body 2 extends, it drives the cylinder linkage block 507 forward. This forward movement of the cylinder linkage block 507 then drives the pressing plate 506 forward, which in turn drives the fiber optic connector 3 forward, thus quickly pressing the fiber optic connector 3 onto the UBC outer shell 4. After the pressing is completed, the cylinder body 2 can be retracted. This retraction causes the cylinder linkage block 507 to move backward. The backward movement of the cylinder linkage block 507 then pulls the wedge block 605 backward. The backward movement of the wedge block 605 forces the lifting block 602 upward, which then pushes out the UBC outer shell 4 secured within the limiting port 504, facilitating unloading.
[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
