Description

Technical Field

[0001] This utility model belongs to the field of sealing strip processing technology, and specifically relates to a top strip rotation positioning device. Background Technology

[0002] With the rapid development of my country's automobile industry, automobile production scale is increasing, and automobile shapes are becoming more diversified. As a component of automobiles, sealing strips are also becoming increasingly diverse in shape and style. After the rubber sealing strips are manufactured, they need to be cut and injection molded to achieve the required shape and size for automobile use, thus forming a complete finished product. During the injection molding process, the sealing strips are cut, resulting in different end face angles and shapes. In the past, the positioning device on the semi-automatic sealing strip mold only used the end face as the positioning reference, and the sealing strip was suspended and extended. If the end face angle of the sealing strip is too large, it will cause the sealing strip to bend during installation due to the inclined surface, making the installation position inaccurate, resulting in product scrap and a reduced production yield. Utility Model Content

[0003] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a top strip rotation positioning device with a simple structure and reasonable design. By setting a positioning component on the positioning device, the positioning device automatically rotates the positioning block downwards through the rotation mechanism during the exit process, thereby removing the sealing strip, thus saving operation steps, reducing strip loading time, and improving production efficiency.

[0004] Technical Solution: To achieve the above objectives, this utility model provides a top strip rotation positioning device, comprising: a guide base, a sliding guide block, a sliding rotating seat, a driving component, a rotating rod, and a cover plate. The sliding guide block and the sliding rotating seat are both disposed within the guide base, and at least one magnet is provided within the sliding rotating seat. The driving component is located at the lower part of the guide base and connected to the sliding guide block. One end of the rotating rod extends into the guide base, passes through a first through hole in the sliding guide block, and connects to the sliding rotating seat. A positioning component is provided at the end of the rotating rod away from the sliding rotating seat. This utility model's top strip rotation positioning device improves the accuracy of strip insertion by providing a top strip rotation positioning device on one side of the strip insertion device. After strip insertion is completed, the positioning device automatically rotates the positioning block downwards during the withdrawal process via a rotating mechanism, thereby removing the sealing strip and saving operation steps, reducing strip insertion time, and improving production efficiency.

[0005] The sliding guide block is provided with a rotating guide groove. After the rotating rod passes through the first through hole, it is connected to the sliding guide block through the guide rod. The sliding guide block is provided with sliding strips on both sides, and the sliding strips are slidably connected to the first sliding groove on the inner wall of the guide base.

[0006] Furthermore, the sliding rotary seat is provided with a second through hole, through which the rotating shaft passes and connects to the rotating rod.

[0007] Furthermore, the cover plate is located above the guide base and has a clearance groove thereon, with the upper part of the drive component passing through the clearance groove.

[0008] Preferably, the guide base is provided with a translation guide groove, and the guide rod passes through the translation guide groove and is provided with a nut on its outer side.

[0009] More preferably, the lower part of the rotating rod is provided with a guide support protrusion. The guide support protrusion can support the sliding guide block.

[0010] Furthermore, the guide base is provided with limiting blocks on both sides, which cooperate with the sliding rotating seat; the outer side of the sliding guide block is provided with an inwardly recessed groove for avoidance. The limiting blocks restrict the running position of the sliding rotating seat.

[0011] Preferably, the positioning component includes a positioning block, with transverse positioning ribs and longitudinal positioning ribs respectively provided on the outer side of the positioning block.

Detailed Implementation

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. Example

[0017] like Figures 1 to 13The top bar rotation positioning device shown includes: a guide base 1, a sliding guide block 2, a sliding rotating seat 3, a driving member 4, a rotating rod 5, and a cover plate 6. The sliding guide block 2 and the sliding rotating seat 3 are both disposed in the guide base 1, and the sliding rotating seat 3 is provided with at least one magnet 31. The driving member 4 is disposed at the lower part and connected to the sliding guide block 2. One end of the rotating rod 5 extends into the guide base 1, passes through the first through hole of the sliding guide block 2, and is connected to the sliding rotating seat 3. The end of the rotating rod 5 away from the sliding rotating seat 3 is provided with a positioning component 51.

[0018] The sliding guide block 2 is provided with a rotating guide groove 21. After the rotating rod 5 passes through the first through hole, it is connected to the sliding guide block 2 via a guide rod 22. The sliding guide block 2 is provided with sliding strips on both sides, and the sliding strips are slidably connected to the first sliding groove on the inner wall of the guide base 1. The shape of the rotating guide groove 21 is the running trajectory of the guide rod 22. It should be noted that the shape of the groove can be adjusted according to actual needs.

[0019] The sliding rotating seat 3 is provided with a second through hole, through which the rotating shaft 32 passes and is connected to the rotating rod 5.

[0020] The cover plate 6 is located above the guide base 1 and has a clearance groove 61 on it. The upper part of the drive member 4 passes through the clearance groove 61.

[0021] like Figure 1 , 6 The guide base 1 described in section 7 is provided with a translation guide groove 11, and the guide rod 22 passes through the translation guide groove 11 and is fitted with a nut. The translation guide groove 11 ensures the normal movement of the guide rod 22. After the nut is locked on the guide rod, it not only prevents it from falling off, but also provides a clearance distance between it and the guide base, so that both ends of the guide rod 22 can move along the normal guide base 1.

[0022] like Figure 4 The lower part of the rotating rod 5 shown is provided with a guide support protrusion 52. When the guide rod 22 moves to the tail of the rotating guide groove 21, the sliding guide block 2 stops moving. At this time, the rotating rod 5 and the positioning block 511 rotate upward and tilt upward, and the guide support protrusion 52 presses against the sliding guide block 2 as a support. like Figure 1 The guide base 1 shown is provided with limiting blocks 12 on both sides, and the limiting blocks 12 cooperate with the sliding rotating seat 3; the outer side of the sliding guide block 2 is provided with an inward groove for avoidance.

[0023] like Figure 4The positioning component 51 shown includes a positioning block 511, with a transverse positioning rib 512 and a longitudinal positioning rib 513 located on the outer side of the positioning block 511. When inserting the sealing strip, the end frame of the sealing strip is mounted on the transverse positioning rib 512, and the end face of the sealing strip is pressed tightly against the longitudinal positioning surface of the longitudinal positioning rib 513. The sealing strip is then installed onto the 3-strip insertion device, completing the strip installation. The transverse positioning rib 512 and the longitudinal positioning rib 513 can respectively position the sealing strip laterally and longitudinally, thereby improving the accuracy of the strip installation position and increasing the yield rate.

[0024] In addition, an insert device 6 is provided at the end of the rotating rod 5 away from the guide base 1. The insert device 6 is located on the lower mold, and a strip skeleton rib 61 is provided on the outer side of the insert device 6. The strip skeleton rib 61 cooperates with the transverse positioning rib 512. The strip skeleton rib 61 can further improve the stability of the sealing strip insert.

[0025] The working principle of the top bar rotation positioning device in this embodiment is as follows: The operator pushes the drive unit 4 forward, which drives the sliding guide block 2 to move forward. The sliding rotating base 3 follows the sliding guide block 2 through the attraction of the magnet 31 on it. At the same time, the sliding rotating base 3 also drives the rotating rod 5 and the positioning block 511 to move until the sliding rotating base 3 moves in front of the limit block 12. At this time, the relative position of the sliding guide block 2 and the sliding rotating base 3 remains unchanged. When the sliding guide block 2 passes the limiting block 12, the sliding rotating base 3 stops moving due to the limitation block 12. At the same time, the rotating rod 5 and the positioning block 511 also stop moving. When the sliding guide block 2 continues to move forward, the rotating guide groove 21 on it drives the guide rod 22 to move upward. At the same time, the guide rod 22 drives the rotating rod 5 and the positioning block 511 to rotate upward around the rotating axis 32. When the guide rod 22 moves to the tail of the rotating guide groove 21, the sliding guide block 2 stops moving. At this time, the rotating rod 5 and the positioning block 511 rotate upward and tilt up. The guide support protrusion 52 presses against the sliding guide block 2 as a support. The rotating positioning device reaches the positioning of the strip. The operator installs the sealing strip end frame onto the transverse positioning rib 512, and then presses the sealing strip end face tightly against the longitudinal positioning surface of the longitudinal positioning rib 513. Finally, the sealing strip is installed onto the 3-insertion device. At this point, the installation is complete. The operator pulls the drive component 4 backward, and similarly the rotating rod 5 and the positioning block 511 will rotate downward and hang down. During the hanging down process, the transverse positioning rib 512 will come out from the end skeleton of the sealing strip, and the rotating positioning device will move backward away from the sealing strip. At this time, the entire strip installation process is completed.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
