Abstract
Description
Technical Field
[0001] This utility model relates to the field of shared bicycle brake box assembly technology, specifically to an adaptive floating pressing mechanism for a shared bicycle brake box assembly machine. Background Technology
[0002] The brake box of a shared bicycle is the core component of the braking system. It is usually integrated near the wheel hub or brake disc of the wheel (front or rear wheel) and is responsible for achieving the braking function through mechanical or hydraulic means. In the production process of shared bicycle brake boxes, they need to be press-fitted to complete the assembly.
[0003] Existing conventional press-fitting devices typically use clamping devices to hold the workpiece and are driven by a press-fitting power unit to perform the press-fitting operation on a fixture table. Specifically, after the workpiece is clamped and fixed, a hydraulic cylinder or electric cylinder is used to send the workpiece into the designated installation position. However, in this process, it is difficult to accurately align the workpiece, and eccentricity problems are prone to occur during press-fitting. Direct press-fitting can also easily lead to problems such as workpiece tilting, incomplete press-fitting, and unstable press-fitting quality.
[0004] Therefore, it is necessary to invent an adaptive floating press mechanism for a shared bicycle brake box assembly machine to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an adaptive floating pressing mechanism for a shared bicycle brake box assembly machine. By cooperating with the mounting frame and the offset correction mechanism, the eccentricity problem is avoided, thus solving the problem of accurately centering the workpiece in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an adaptive floating pressing mechanism for a shared bicycle brake box assembly machine, comprising a mounting frame, an offset correction mechanism disposed inside the mounting frame, the offset correction mechanism comprising an outer cylinder disposed inside the mounting frame, a pressing cylinder fixedly connected to the top of the outer cylinder, a linkage ring fixedly connected to the output end of the pressing cylinder, a pressing rod fixedly connected to the top wall of the linkage ring, three sets of pressing blocks fixedly connected to the bottom end of the linkage ring and evenly distributed around the center of the linkage ring, a correction gripper abutting below the pressing block, a buffer rubber pad fixedly connected to the inner side wall of the correction gripper, and a pressing head fixedly connected to the bottom end of the pressing rod. The linkage ring drives the pressing blocks to press the correction gripper downwards, causing the correction gripper and the buffer rubber pad to move the workpiece directly below the pressing rod, thereby avoiding the problem of eccentricity during pressing.
[0007] Preferably, the inner wall of the outer cylinder is fixedly connected with three sets of sliding rods, and the outer wall of the sliding rod is sleeved with a return spring and the correction gripper slides on the outer wall of the sliding rod. The correction gripper is reset along the sliding rod by the return spring.
[0008] Preferably, a movable cylinder is fixedly connected to the top of the mounting frame, and the output end of the movable cylinder is fixedly connected to the top of the pressing cylinder. Activating the movable cylinder drives the pressing cylinder to rise and fall.
[0009] Preferably, the inner wall of the mounting bracket is provided with two sets of movable grooves, and a fixed block is slidably connected inside the movable groove. The fixed block is fixedly connected to both sides of the outer cylinder, and the outer cylinder is prevented from shifting by the cooperation between the movable groove and the fixed block.
[0010] Preferably, the inner wall of the mounting bracket is bolted with a height limiting block, which is located below the fixing block and limits the lowest point of the outer cylinder.
[0011] Preferably, a lubricating layer is fixedly connected to the top of the correction gripper, and a sound insulation layer is fixedly connected to the inner side wall of the outer cylinder, thereby achieving sound insulation and reducing noise.
[0012] Preferably, the inner wall of the sound insulation layer is fixedly connected with a number of connecting blocks, and the inner wall of the connecting blocks is fixedly connected with an inner cylinder. The cooperation between the connecting blocks and the inner cylinder protects the sound insulation layer and extends its service life.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] By coordinating the mounting bracket and the offset correction mechanism, the movable cylinder is activated to drive the outer cylinder and the fixed block to descend along the movable groove to the position of the height limit block. The pressing cylinder is activated to drive the linkage ring and the pressure block to descend. The pressure block presses the correction jaws, causing the correction jaws to move along the sliding rod towards the center, thereby correcting the workpiece and placing the workpiece directly below the pressing rod. Under the action of the linkage ring, the pressing rod comes into contact with the workpiece. When the linkage ring rises, the return spring drives the correction jaws to reset, thus avoiding eccentricity during pressing. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model provides, for example Figure 1-4The diagram illustrates an adaptive floating pressing mechanism for a shared bicycle brake box assembly machine. It includes a mounting frame 1, with an offset correction mechanism 2 inside the mounting frame 1. The offset correction mechanism 2 includes an outer cylinder 201 located inside the mounting frame 1. A pressing cylinder 202 is fixedly connected to the top of the outer cylinder 201. A linkage ring 203 is fixedly connected to the output end of the pressing cylinder 202. A pressing rod 205 is fixedly connected to the top wall of the linkage ring 203. Three sets of pressing blocks 204 are fixedly connected to the bottom of the linkage ring 203, and the pressing blocks 204 are evenly distributed around the center of the linkage ring 203. A correction gripper 209 abuts against the lower part of each pressing block 204. A buffer rubber pad 210 is fixedly connected to the inner wall of the calibrating gripper 209. A pressing head 208 is fixedly connected to the bottom end of the pressing rod 205. The pressing block 204 is driven by the linkage ring 203 to press the calibrating gripper 209 downward, so that the calibrating gripper 209 and the buffer rubber pad 210 move the workpiece directly below the pressing rod 205, thereby avoiding the problem of eccentricity during pressing. Three sets of sliding rods 206 are fixedly connected to the inner wall of the outer cylinder 201. A return spring 207 is sleeved on the outer wall of the sliding rod 206, and the calibrating gripper 209 slides on the outer wall of the sliding rod 206. The return spring 207 causes the calibrating gripper 209 to move along the sliding rod 205. 06 Reset: A movable cylinder 3 is fixedly connected to the top of the mounting frame 1. The output end of the movable cylinder 3 is fixedly connected to the top of the pressing cylinder 202. Activating the movable cylinder 3 drives the pressing cylinder 202 to rise and fall. Two sets of movable grooves 4 are opened on the inner side wall of the mounting frame 1. Fixed blocks 5 are slidably connected inside the movable grooves 4. The fixed blocks 5 are fixedly connected to both sides of the outer cylinder 201. The cooperation between the movable grooves 4 and the fixed blocks 5 prevents the outer cylinder 201 from shifting. A height limiting block 6 is bolted to the inner side wall of the mounting frame 1. The height limiting block 6 is located below the fixed blocks 5. The height limiting block 6 limits the lowest point of the outer cylinder 201. The mounting frame 1 and the offset correction are then implemented. With the cooperation of mechanism 2, the movable cylinder 3 is activated to drive the outer cylinder 201 and the fixed block 5 to descend along the movable groove 4 to the position of the height limit block 6. The pressing cylinder 202 is activated to drive the linkage ring 203 and the pressing block 204 to descend. The pressing block 204 presses the correction gripper 209 to move along the sliding rod 206 towards the center, thereby correcting the workpiece so that the workpiece is directly below the pressing rod 205. Under the action of the linkage ring 203, the pressing rod 205 contacts the workpiece. When the linkage ring 203 rises, the return spring 207 drives the correction gripper 209 to reset, thereby avoiding the problem of eccentricity during pressing.
[0024] Refer to the instruction manual appendix Figure 1-4 The top of the correction gripper 209 is fixedly connected to a lubricating layer 10, and the inner wall of the outer cylinder 201 is fixedly connected to a sound insulation layer 7. The sound insulation layer 7 is used to achieve sound insulation and reduce noise. Several sets of connecting blocks 8 are fixedly connected to the inner wall of the sound insulation layer 7. The inner wall of the connecting block 8 is fixedly connected to an inner cylinder 9. The cooperation between the connecting block 8 and the inner cylinder 9 protects the sound insulation layer 7 and extends its service life.
[0025] The working principle of this practical application is as follows:
[0026] Refer to the instruction manual appendix Figure 1-4 When the gate box needs to be pressed, the gate box is sent to the bottom of the mounting frame 1 through the conveying mechanism. The movable cylinder 3 is activated to drive the outer cylinder 201 and the fixed block 5 to descend along the movable groove 4 to the position of the height limit block 6. The pressing cylinder 202 is activated to drive the linkage ring 203 and the pressure block 204 to descend. The pressure block 204 presses the correction gripper 209 to move the correction gripper 209 along the sliding rod 206 towards the center, thereby correcting the workpiece and placing the workpiece directly below the pressing rod 205. Under the action of the linkage ring 203, the pressing rod 205 contacts the workpiece. When the linkage ring 203 rises, the return spring 207 drives the correction gripper 209 to reset, thereby avoiding the problem of eccentricity during pressing. During the pressing process, the frictional resistance between the pressure block 204 and the correction gripper 209 is reduced by the lubrication layer 10, and the sound insulation layer 7 is used to reduce noise.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
