Description

Technical Field

[0001] The utility model relates to the technical field of bushing installation, in particular to a tool for pressing a rubber bushing. Background Art

[0002] Bushing press fitting is a processing method that presses one object (called a bushing) into another object (called a matrix). It is commonly used in machinery manufacturing, automobile manufacturing, aerospace and other industries to connect and fix parts. In order to make the vehicle obtain good handling stability and ride comfort, a large number of rubber parts are used at the connection positions of the vehicle's suspension system, such as the connection between the shock absorber and the body, the connection between the suspension rod and the steering knuckle, and the connection between the suspension rod and the body. These rubber connectors have a great influence on the shock absorption, noise reduction and suspension performance of the vehicle. In the vehicle's suspension system, more and more rubber bushings are used. Their main functions are shock absorption, noise isolation, and increased service life, which play a vital role in the vehicle's operational stability. In the current processing and assembly of automotive parts, it is usually necessary to press the rubber bushing assembly into the corresponding part shaft hole.

[0003] In the existing patent application with application number CN201921701321.9, a rubber bushing pressing device is proposed. Since the size of its pressing head is fixed, the pressing head can only press a rubber bushing of a fixed diameter, which leads to poor versatility of the pressing device. Therefore, it needs to be improved. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a tool for pressing a rubber bushing comprises a support plate 1, which is fixedly mounted on the upper end of a workbench 2, a mounting bracket 3 is mounted on the upper end of the workbench 2, a driving cylinder 4 is mounted on the mounting bracket 3, a mounting plate 5 is mounted on the lower end of the telescopic rod of the driving cylinder 4, a limiting column 7 is fixedly mounted on the upper end of the support plate 1, the mounting bracket 3 is fixedly connected to the workbench 2, the driving cylinder 4 is fixedly connected to the mounting bracket 3, and the mounting plate 5 is fixedly connected to the telescopic rod of the driving cylinder 4. When the rubber bushing needs to be pressed into the axial hole of the mother body, the mother body and the rubber bushing can be sequentially sleeved on the limiting column 7, and at the same time, the mother body and the rubber bushing can be made coaxial with the limiting column 7, and then the driving cylinder 4 can be started to push the mounting plate 5 downward, thereby finally pressing the rubber bushing into the axial hole of the mother body.

[0021] Furthermore, a pressure head assembly 6 is installed at the lower end of the mounting plate 5, and the pressure head assembly 6 is composed of a fixed plate 8, a first threaded rod 9, a mounting block 10, a first connecting plate 11, a second threaded rod 12, an adjustable pressure rod 13 and a second connecting plate 14. The first threaded rod 9 is rotatably mounted on the fixed plate 8, there are two mounting blocks 10 and they are symmetrically mounted on the first threaded rod 9, there are two first connecting plates 11 and they are fixedly mounted on one end of the two mounting blocks 10, there are two second threaded rods 12 and they are rotatably mounted on the two first connecting plates 11, there are two adjustable pressure rods 13 and they are respectively located below the two mounting blocks 10, there are two second connecting plates 14 and they are fixedly mounted on one end of the two adjustable pressure rods 13, and the second connecting plate 1 4 is installed on the second threaded rod 12 at the same time, the fixing plate 8 on the pressure head assembly 6 is fixedly installed at the lower end of the mounting plate 5, and the fixing plate 8 is located between the two mounting blocks 10, the mounting block 10 on the pressure head assembly 6 contacts the lower end of the mounting plate 5, a threaded hole is opened on the mounting block 10, and the mounting block 10 is installed on the first threaded rod 9 through the threaded hole, and the second connecting plate 14 is also opened on the second threaded rod 12 through the threaded hole. Before starting the driving cylinder 4 to push the mounting plate 5 downward, the distance between the two adjustable pressure rods 13 can be adjusted according to the diameter of the rubber bushing, and the distance between the adjustable pressure rod 13 and the mounting block 10 can be adjusted according to the height of the rubber bushing. The method is to firstly adjust the first threaded rod 9 to a certain height. When the rod 9 rotates on the fixed plate 8, the mounting block 10 will move on the first threaded rod 9, so that the two mounting blocks 10 will approach or move away from each other, and then the mounting block 10 will drive the adjustable pressure rod 13 to move through the first connecting plate 11 and the second threaded rod 12. When the spacing between the two adjustable pressure rods 13 matches the diameter of the rubber bushing, the rotation of the first threaded rod 9 can be stopped, and then the distance between the adjustable pressure rod 13 and the mounting block 10 can be adjusted by rotating the second threaded rod 12; when the driving cylinder 4 pushes the mounting plate 5 downward, the pressure head assembly 6 will also move downward, and finally the adjustable pressure rod 13 will press the rubber bushing into the axial hole of the mother body. The pressure head assembly 6 is composed of a connecting plate 11, a second threaded rod 12, an adjustable pressure rod 13 and a second connecting plate 14. The spacing between the two adjustable pressure rods 13 on the pressure head assembly 6 can be adjusted, so that the pressure head assembly 6 can be adjusted according to rubber bushings of different diameters, thereby enabling the pressure head assembly 6 to press rubber bushings of different diameters, and ultimately improving the versatility of the tooling. By setting a mounting block 10 and an adjustable pressure rod 13 separated from each other, and using the first connecting plate 11, the second threaded rod 12 and the second connecting plate 14 to connect the mounting block 10 and the adjustable pressure rod 13 together, the spacing between the mounting block 10 and the adjustable pressure rod 13 can be adjusted, thereby enabling the tooling to press rubber bushings of different heights.
