Description

Technical Field

[0001] The utility model relates to the field of industrial manufacturing, and more specifically, to a rectangular ring installation device. Background Art

[0002] With the continuous development of industrial manufacturing technology, automation and intelligence have become important trends in modern production lines. As an indispensable component in many mechanical equipment, the installation efficiency and accuracy of rectangular rings directly affect the overall quality and production efficiency of the product. Traditional manual installation methods are not only costly, but also often accompanied by problems such as low installation efficiency and insufficient installation accuracy. Therefore, people have developed corresponding installation equipment to meet these challenges.

[0003] During the installation of the rectangular ring of the brake caliper, the rectangular ring needs to be accurately installed into the caliper body. Usually, the installation area of ​​the rectangular ring is designed to be slightly larger than the adjacent area to fix and improve the installation stability of the rectangular ring. During installation, pressure needs to be applied to the rectangular ring to cause it to deform. Only after the volume is reduced can it smoothly enter the caliper body and reach the designated installation position.

[0004] Since the rectangular ring has a certain elasticity, when it is subjected to an extrusion force in one direction, it will deform in other directions and may not meet the minimum volume requirement for entering the pliers body; therefore, the current installation equipment on the market is usually equipped with at least three extrusion devices to extrude the rectangular ring to prevent the rectangular ring from deforming in unexpected directions during the extrusion process; however, this design increases the complexity of the equipment and the number of parts. In addition, if the extrusion devices fail to keep in sync during the extrusion process, the rectangular ring may be excessively deformed in the direction of the last extrusion device after completing part of the extrusion, making the area more prominent, and thus causing the rectangular ring to be unable to be smoothly placed inside the pliers body; therefore, it is very important to ensure the synchronization of the extrusion devices to achieve uniform deformation of the rectangular ring, ensure that the rectangular ring can be stably and accurately loaded into the pliers body, and complete the assembly.

[0051] In the present invention, the extrusion block 16 includes a positive extrusion portion 161 and a side extrusion portion 162 extending toward the rectangular ring pre-assembled frame 12; the positive extrusion portion 161 and the side extrusion portion 162 enclose a pressure space 165 having an end notch 163 and a side notch 164, the end notch 163 corresponds to the positive extrusion portion 161, and the side notch 164 corresponds to the side extrusion portion 162; the positive extrusion portions 161 of the extrusion blocks 16 of the left extrusion module 13 and the right extrusion module 14 correspond to each other, and the side extrusion portions 162 of the extrusion blocks 16 of the left extrusion module 13 and the right extrusion module 14 are staggered with each other. Open; the extrusion blocks 16 of the left extrusion module 13 and the right extrusion module 14 are driven by the extrusion cylinder 15 to approach each other, and the two pressure spaces 165 are combined to form an extrusion space 166; the two extrusion blocks 16 in the left and right extrusion modules 14 symmetrically and simultaneously extrude the rectangular ring in four directions, so that the rectangular ring is uniformly deformed to ensure that the rectangular ring can be stably and accurately loaded into the inside of the pliers body and complete the assembly; at the same time, the equipment can achieve uniform extrusion of the rectangular ring through the two devices of the left and right extrusion modules 14, thereby reducing the number of parts of the equipment and reducing the complexity of the equipment.

[0052] In this embodiment, the extrusion block 16 is in an "L" shape, and the positive extrusion portion 161 moves toward or away from the rectangular ring pre-assembly frame 12 under the drive of the extrusion cylinder 15, and the side extrusion portion 162 is arranged on one side of the positive extrusion portion 161; through the coordinated work of the positive extrusion portion 161 and the side extrusion portion 162 of the two extrusion blocks 16, the extrusion process can more comprehensively cover all surfaces of the rectangular ring, ensuring that the rectangular ring is extruded into place evenly and stably as much as possible.

[0053] In this embodiment, the size of the extrusion space 166 changes with the movement of the extrusion blocks 16 of the left extrusion module 13 and the right extrusion module 14; the extrusion blocks 16 of the left and right extrusion modules 14 approach each other under the drive of the extrusion cylinder 15, and block the end notches 163 and side notches 164 of each other through their own positive extrusion parts 161 and side extrusion parts 162, thereby forming an extrusion space 166; and when the extrusion blocks 16 of the left and right extrusion modules 14 just form the extrusion space 166, this state is the preparatory state of the rectangular ring pre-installed component 1, and in this state the extrusion space 166 is the largest; subsequently, the extrusion blocks 16 of the left and right extrusion modules 14 continue to approach each other and enter the extrusion state, and the corresponding extrusion space 166 gradually becomes smaller until the rectangular ring is extruded to meet the installation conditions.

[0054] In this embodiment, a first recess 167 opening toward the side notch 164 is provided on the inner wall of the side extrusion portion 162 corresponding to the pressure space 165, the first recess 167 is arc-shaped, and an arc surface transition is adopted between the first recess 167 and the inner wall of the side extrusion portion 162; a second recess 168 opening toward the end notch 163 is provided on the surface of the positive extrusion portion 161 facing the rectangular ring pre-assembled frame 12, the second recess 168 is arc-shaped, and an arc surface transition is adopted between the second recess 168 and the inner wall of the side extrusion portion 162; the arc angle of the first recess 167 is greater than the arc angle of the second recess 168; the first recess 167 is provided in the middle area of ​​the pressure space 165 corresponding to the side extrusion portion 162, and the inner diameter of the pressure space 165 where the first recess 167 is provided is greater than the inner diameter of the second recess 168 provided 8; the size and opening size of the first recess 167 are larger than the size and opening size of the second recess 168; the first recess 167 and the second recess 168 adopt an arc structure, and an arc transition is adopted between the first recess 167 and the inner wall of the side extrusion portion 162, which can effectively disperse the stress concentration phenomenon generated during the extrusion process, and reduce the direct impact of right angles or sharp edges on the rectangular ring through the arc transition, thereby reducing the risk of damage to the rectangular ring during the extrusion process; the first recess 167 has a larger arc angle, size and opening, so that the rectangular ring pre-assembled component 1 can accommodate a rectangular ring that is not squeezed under normal circumstances in the preparatory state, while the second recess 168 plays a role in the later stage of extrusion, and through its smaller arc angle and size, it further finely controls the deformation of the rectangular ring to achieve higher shape accuracy.

[0055] In this embodiment, in the preparatory state of the rectangular ring pre-assembly component 1, the center lines of the first recess 167 of the extrusion block 16 in the left extrusion module 13 and the right extrusion module 14 are on the same straight line, and the center lines of the second recess 168 of the extrusion block 16 in the left extrusion module 13 and the right extrusion module 14 are on the same straight line, so that the rectangular ring after extrusion is more uniform and easy to install.

[0056] In this embodiment, an extrusion limit groove 121 is provided on the top of the rectangular ring pre-assembly frame 12, and openings for the extrusion blocks 16 to enter the extrusion limit groove 121 are provided at both ends of the rectangular ring pre-assembly frame 12; the extrusion blocks 16 are located in the extrusion limit groove 121 and can movably cooperate with it, and the surfaces of the two extrusion blocks 16 on the side away from the side notch 164 abut against the inner wall of the extrusion limit groove 121, and the surfaces of the two extrusion blocks 16 on the side corresponding to the side notch 164 abut against each other, and gradually close the end notch 163 and the side notch 164 of each other during the movement to form an extrusion space 166; through the setting of the extrusion limit groove 121, the extrusion blocks 16 can perform the extrusion work more stably.

[0058] In this embodiment, the lower surface of the limiting movable plate 172 abuts against the upper surface of the extrusion block 16 to further limit the rectangular ring to prevent it from deforming or displacing upward during the extrusion process.
