Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing and automated assembly technology, and in particular to a press-fit floating anti-gravity mechanism. Background Technology
[0002] In mechanical assembly, the press-fitting process is a crucial step, widely used in industries such as automotive, machinery, and electronics. Existing press-fitting mechanisms often suffer from the following problems during operation: Firstly, due to inevitable positional deviations during workpiece positioning, traditional rigid press-fitting mechanisms cannot effectively compensate for these deviations, easily leading to reduced press-fitting accuracy or even workpiece damage. Secondly, when press-fitting workpieces with a certain weight, gravity can adversely affect the press-fitting process, resulting in uneven force distribution and impacting press-fitting quality and stability.
[0003] Some press-fitting equipment attempts to use simple floating structures to compensate for positional deviations, but these floating structures can usually only float in one direction, with limited compensation range, and cannot solve the problem of gravity effects. At the same time, existing mechanisms have difficulty in quickly achieving high-precision centering during the initial positioning stage of the workpiece, further affecting press-fitting efficiency and accuracy. Utility Model Content
[0004] The purpose of this invention is to solve the problems of existing mechanisms, such as difficulty in compensating for positioning deviations, the influence of gravity on the distribution of pressing force, the fact that some simple floating structures only float in one direction with limited compensation range, which cannot solve the gravity problem, and the difficulty in quickly and accurately centering the initial positioning, thus affecting efficiency and accuracy. Therefore, this invention proposes a pressing floating anti-gravity mechanism.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a press-fit floating anti-gravity mechanism, comprising: A fixed column, with air grooves formed inside the fixed column; An extension rod is provided, with a convex platform mounted on top of the extension rod. A gap is formed between the convex platform and the air groove, and the gap gradually decreases from the inside to the outside.
[0006] Preferably, the fixing post further includes a drive groove formed therein, a drive ball is rotatably connected inside the drive groove, and an extension rod is fixedly installed at the top position of the drive ball.
[0007] Preferably, the air pump is fixedly inserted inside the fixed column, and the air pump continuously pressurizes the inside of the air tank.
[0008] Preferably, a float seat is mounted on top of the convex platform; A fixing base is installed at the bottom of the fixing column; A set of spring columns is fixedly connected between the fixed seat and the floating seat, and the fixed seat and the floating seat are symmetrically arranged based on the set of spring columns.
[0009] Preferably, a first magnet is installed at the bottom of the floating seat and is fixedly sleeved between the outer walls of the convex platform.
[0010] Preferably, a second magnet is fixedly sleeved between the outer walls of the fixed column, and a repulsive force is generated between the first magnet and the second magnet.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the air pump continuously pressurizes the air groove, and the gap between the convex platform and the air groove gradually decreases from the inside to the outside. When the floating seat is eccentric, the gas pressure on the side with the smaller gap is higher, which will push the convex platform to move towards the side with the larger gap until the center is aligned, quickly achieving high-precision centering, improving the pressing efficiency and accuracy, and breaking through the limitations of traditional single-direction floating. It can effectively compensate for multi-dimensional positional deviations generated during the workpiece positioning process, greatly improving the deviation adaptability. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0016] Please see Figure 1 and Figure 2As shown, this utility model provides a technical solution: a press-fit floating anti-gravity mechanism, in which an air groove 42 is opened inside a fixed column 4, a convex platform 71 is installed on the top of an extension rod 7, and a floating seat 2 is also installed on the top of the convex platform 71. When the floating seat 2 deviates from its position, it causes the convex platform 71 to tilt to one side, and a gap is formed between the convex platform 71 and the air groove 42. When the air cavity is aligned, its periphery is in a uniform distribution state, and the air cavity gradually shrinks from the inside to the outside.
[0017] Furthermore, such as Figure 1 As shown, the fixed column 4 also includes a drive groove 41 formed inside it. The drive ball 6 is rotatably connected inside the drive groove 41. The extension rod 7 is fixedly installed at the top position of the drive ball 6. When the drive ball 6 rotates inside the drive groove 41, it changes the position of the extension rod 7.
[0018] Furthermore, such as Figure 1 The air pump 5 is fixedly inserted inside the fixed column 4, and the output end of the air pump 5 can be connected to the inside of the air groove 42. The air pump 5 continuously pressurizes the inside of the air groove 42, thereby maintaining a high pressure state inside the air groove 42. When the gas is under high pressure, the high pressure gas can be discharged from the gap between the convex platform 71 and the air groove 42. When the gap is unevenly distributed, the gas ejected generates a uniform radial thrust on the workpiece because the air chamber is annularly distributed. When the float seat 2 is eccentric, the gap between the convex platform 71 and the air chamber opening is uneven. The gas pressure is higher on the side with a smaller gap, and the thrust on the workpiece is greater, pushing the convex platform 71 to move towards the side with a larger gap until the center of the convex platform 71 is aligned with the center of the pressing body, thus achieving automatic centering.
[0019] Furthermore, such as Figure 1 As shown, the floating seat 2 is installed on the top of the convex platform 71, and the fixed seat 1 is installed on the bottom of the fixed column 4. A set of spring columns 3 are fixedly connected between the fixed seat 1 and the floating seat 2. The fixed seat 1 and the floating seat 2 are symmetrically arranged based on the set of spring columns 3. The set of spring columns 3 is used to stabilize the fixed seat 1 and the floating seat 2 and prevent them from shaking.
[0020] Furthermore, such as Figure 1 As shown, the first magnet 8 is installed at the bottom of the floating seat 2. The first magnet 8 is fixedly sleeved between the outer walls of the convex platform 71. The first magnet 8 can swing with the swing of the convex platform 71.
[0021] Furthermore, such as Figure 1 The second magnet 9 is fixedly sleeved between the outer walls of the fixed column 4. The first magnet 8 and the second magnet 9 generate a repulsive force, which can push the floating seat 2 upward, so that the floating seat 2 maintains a suspended state.
[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
