Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a cam-driven press-fitting mechanism. Background Technology

[0002] In the assembly of some electronic components, pressing the assembled products is a crucial step. Typically, to avoid using complex control systems to adjust the lifting speed of the pressing assembly and thus reduce system response time, existing technologies often employ a vertical cam structure to drive the pressing assembly's lifting and lowering.

[0003] Specifically, this vertical cam structure, during operation, drives the movement of related components through the rotation of the cam, thereby achieving the lifting and lowering of the pressing assembly. However, existing vertical cam structures have some significant shortcomings. First, they cannot precisely control the downward pressure of the pressing assembly. This can lead to unstable pressure applied to the product during the pressing process, affecting product quality and performance. Second, the pressing action of the pressing assembly cannot be flexibly controlled according to actual needs. With the vertical cam continuously rotating, the vertical cam structure drives the pressing assembly to continuously lift and lower for the pressing action. However, in some cases, it is not necessary to press the assembled product; in such cases, continuous pressing is not only redundant but also leads to unnecessary mechanical wear. This mechanical wear negatively impacts the service life of related components and increases maintenance costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cam-driven pressing mechanism.

[0005] The technical solution of this utility model is: it includes a mounting plate, a vertically moving component disposed on the mounting plate, and a pressing component for pressing the assembled product;

[0006] The vertical moving component includes a vertical cam and a swing rod. The swing rod swings around the swing axis with the cooperation of the vertical cam. The pressing component is connected to the free end of the swing rod and moves up and down with the swing rod. A swing cylinder is also hinged to the bottom of the mounting plate. The piston rod of the swing cylinder is pivotally connected to the free end of the swing rod.

[0007] A further technical solution is that the free end of the swing rod is connected to the pressing assembly through a vertical moving block, and the vertical moving block is provided with a horizontal groove extending in the horizontal direction, and the free end of the swing rod moves along the horizontal groove.

[0008] A further technical solution is that a transmission roller is pivotally connected to the free end of the swing rod, and the transmission roller rolls within the horizontal groove.

[0009] A further technical solution is that the vertical cam is a cam disk structure, and the driving roller in the middle of the swing rod is in rolling connection with the cam circumferential surface of the vertical cam.

[0010] A further technical solution is that the mounting plate is provided with a vertical rail extending in the vertical direction, and the pressing component moves with the vertical moving block and is slidably connected to the mounting plate through the vertical rail.

[0011] A further technical solution is that the vertical rails are provided in two sets, and the two sets of vertical rails are arranged at intervals on the mounting plate.

[0012] A further technical solution is as follows: a synchronous transmission component is provided on the side of the mounting plate opposite to the vertical moving component, and the vertical cam is connected to the synchronous transmission component through a synchronous shaft.

[0013] A further technical solution is as follows: the synchronous transmission assembly includes two sets of synchronous pulleys spaced apart on the mounting plate, the two sets of synchronous pulleys are connected by a synchronous belt drive, one set of synchronous pulleys is mounted on a synchronous shaft, and the other set of synchronous pulleys is connected to an external drive assembly.

[0014] A further technical solution is that a tensioning wheel is provided between the two sets of synchronous pulleys, and the tensioning wheel is provided with an adjustment hole for adjusting the installation height at the corresponding position on the mounting plate.

[0015] The beneficial technical effects of this utility model are: the vertical moving component drives the pressing component to lift and lower to press the assembled product; at the same time, with the cooperation of the swing cylinder, the downward pressure of the pressing component can be precisely controlled, improving the pressing accuracy; moreover, the piston rod of the swing cylinder pushes out to drive the swing rod to disengage from the vertical cam, thereby reducing unnecessary pressing actions of the pressing component, reducing unnecessary mechanical wear, increasing the service life of related components, and reducing maintenance costs.

Pivot connection. Detailed Implementation

[0021] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0022] like Figures 1 to 3 As shown, the cam-driven pressing mechanism of this utility model includes a mounting plate 1, a vertical moving component 2 and a synchronous transmission component 3 respectively disposed on opposite sides of the mounting plate 1, and a pressing component 4 connected to the vertical moving component 2; under the transmission action of the synchronous transmission component 3, the vertical moving component 2 drives the pressing component 4 to press the assembled product.

[0023] Specifically, the vertical moving component 2 includes a vertical cam structure and a vertical rail 21, the track of which extends in the vertical direction; the vertical cam structure includes a vertical cam 22, a swing rod 23 and a vertical moving block 24, one end of the swing rod 23 is hinged to the mounting plate 1 through a swing rod shaft 25, the middle part of the swing rod 23 is provided with a drive roller 26 that rotates in cooperation with the vertical cam 22, and the other free end of the swing rod 23 is pivotally connected to a transmission roller 27, the vertical moving block 24 is provided with a horizontal groove extending in the horizontal direction, and the transmission roller 27 rolls and moves in the horizontal groove.

[0024] The pressing assembly 4 is fixedly connected to the vertical moving block 24 via the vertical connecting plate 5, and is slidably connected to the mounting plate 1 via the vertical moving block 24 via the vertical rail 21.

[0025] To balance the weight of the vertical connecting plate 5 and to ensure that the vertical connecting plate 5 moves in a precise vertical direction, in this embodiment, two sets of vertical rails 21 are provided, and the two sets of vertical rails 21 are spaced apart on the mounting plate 1. One set of vertical rails 21 is located at the end of the mounting plate 1 near the pressing assembly 4.

[0026] The vertical cam 22 has a cam disk structure, and the driving roller 26 is in rolling connection with the cam circumferential surface of the vertical cam 22.

[0027] The synchronous transmission assembly 3 includes two sets of synchronous pulleys 31 spaced apart on the mounting plate 1. The two sets of synchronous pulleys 31 are connected by a synchronous belt. One set of synchronous pulleys 31 is connected to the vertical cam 22 via a synchronous shaft, and the other set of synchronous pulleys 31 is connected to an external drive assembly.

[0028] Furthermore, a tensioning pulley 32 is provided between the two sets of synchronous pulleys 31. The tensioning pulley 32 is provided with an adjustment hole for adjusting the installation height at a corresponding position on the mounting plate 1, and the tensioning pulley 32 is adjustablely mounted on the adjustment hole. By adjusting the position of the tensioning pulley 32 on the mounting plate 1, the pressure applied by the tensioning pulley 32 to the synchronous belt is adjusted to maintain the tension of the synchronous belt; at the same time, the wrap angle of the synchronous belt is increased to improve the friction between the synchronous belt and the synchronous pulleys 31, thereby improving the transmission efficiency.

[0029] Furthermore, to achieve precise pressing of the assembled products, a swing cylinder 6 is also hinged to the bottom of the mounting plate 1, such as... Figure 4 The piston rod end of the swing cylinder 6 is pivotally connected to the free end of the swing rod 23 via the pivot connector 7. As the piston rod of the swing cylinder 6 extends and retracts, the swing rod 23 swings around the swing rod axis 25.

[0030] During operation, when the pressing assembly 4 descends to the pressing position with the vertical moving block 24, the piston rod of the swing cylinder 6 retracts, driving the swing rod 23 to perform the pressing operation, and the downward pressure of the pressing assembly 4 is precisely controlled by the swing cylinder 6.

[0031] Simultaneously, when the piston rod of the swing cylinder 6 is pushed out, the swing rod 23 swings around the swing rod shaft 25 and disengages from the vertical cam 22. The pressing assembly 4 no longer continuously lifts and lowers to perform the pressing action, reducing the mechanical wear of related components. For example, the vertical cam 22, drive roller 26, transmission roller 27, and swing rod 23 will experience reduced wear and extended service life when the pressing assembly 4 stops unnecessary lifting and lowering actions, thus reducing maintenance costs.

[0032] The working principle of this pressing mechanism is as follows: The external drive assembly drives the vertical cam 22 to rotate via the synchronous transmission assembly 3. Under the cooperation of the drive roller 26 and the vertical cam 22, the swing rod 23 swings and drives the pressing assembly 4 to descend to the pressing position. At the same time, under the contraction of the piston rod of the swing cylinder 6, the pressing assembly 4 applies a controllable and precise pressing force to the assembled product. After pressing is completed, the piston rod of the swing cylinder 6 pushes out, causing the pressing assembly 4 to stop its lifting and lowering action.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
