Description

Technical Field

[0001] This invention relates to the field of bearing assembly technology, and more particularly to a rubber bearing assembly mechanism. Background Technology

[0002] Rubber bearings, also known as flexible needle roller bearings, are currently assembled manually by pressing the gaskets, needle roller cages, and spring rings into the rubber outer sleeve. This assembly process is inefficient, time-consuming, labor-intensive, and time-consuming.

[0003] In the prior art, the flexible needle roller bearing described in CN201720171013.4 includes a frame, a positioning mechanism, an outer ring conveying mechanism, an inner ring conveying mechanism, and a controller. Assembly is performed by adjusting the clamp at the outer end of the piston rod driven by the cylinder to extend and retract into the working chamber. This saves a lot of space, shortens the assembly process, and reduces the tilting of the bearing skeleton or cage inside the outer sleeve, thereby improving product quality. The above structure facilitates the assembly of flexible needle roller bearings to a certain extent.

[0004] However, during assembly, the assembly cycle of a single bearing is too long, and there are many internal components in the bearing during the assembly process. This results in uneven stress on the components, which can easily lead to product damage due to lack of skill or insufficient strength. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a rubber bearing assembly mechanism to solve the problems of excessively long bearing assembly cycle and uneven stress on the product during the assembly process.

[0006] To achieve the above objectives, the present invention provides a rubber bearing assembly mechanism, comprising: a machine base, a support column provided on the top of the machine base, a rubber bearing sleeved on the support column, a pressure head provided above the rubber bearing and cooperating with the rubber bearing, the pressure head being connected to an installation part for controlling the lifting and lowering of the pressure head, and a support part provided at the bottom of the support column, the support part including a support pad located below the rubber bearing, the support pad being sleeved on the outside of the support column;

[0007] The installation unit controls the pressure head to descend, which in turn pushes the rubber bearing downward, causing the rubber bearing to contact the support pad, and then the rubber bearing is assembled in the lower part of the support column.

[0008] Preferably, the support column is fixedly installed from a limiting section and a stepped section. The top edge of the limiting section is chamfered. The stepped section is detachably installed on the upper surface of the machine tool and is formed by stacking adjacent bosses. The support pad is sleeved on the upper end of the stepped section.

[0009] Preferably, the support part further includes a floating support frame, which is slidably installed in a positioning hole opened at the top of the step section. The floating support frame is distributed around the bottom of the support pad, and a compression spring is fixedly connected to the end of the floating support frame. A stop screw is provided at the bottom of the compression spring.

[0010] Preferably, there are at least three floating support frames.

[0011] Preferably, the mounting part is connected to the machine base via a guide.

[0012] Preferably, the guide is a vertical guide rail, and the pressure head is slidably connected to the vertical guide rail.

[0013] Preferably, the mounting part includes a cylinder connected to the guide, and a pressure head is fixedly connected to the output end of the cylinder.

[0014] Preferably, the pressure head has a through hole inside, the support column corresponds to the through hole, and the diameter of the through hole is larger than the top diameter of the support column.

[0015] Preferably, the pressure head is an L-shaped structural component.

[0016] The beneficial effects of this invention are as follows: By assembling the rubber bearing through the mounting part, during the component pressing process, while the pressure head is kept horizontal, the rubber outer sleeve can maintain its initial horizontal state as it is pressed down outside other components. Meanwhile, the support pads in the support part ensure that the force on each component is uniform throughout the entire product entering the rubber outer sleeve, thereby improving assembly efficiency, avoiding excessively long assembly cycles, and making the assembly process reasonable, stable, safe, reliable, and ensuring accuracy and quality.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0025] like Figures 1-5 As shown, a rubber bearing assembly mechanism includes: a machine base 1, characterized in that a support column 6 is provided on the top of the machine base 1, a rubber bearing is sleeved on the support column 6, a pressure head 4 is provided above the rubber bearing and is configured to cooperate with the rubber bearing, the pressure head 4 is connected to an installation part for controlling the lifting and lowering of the pressure head 4, and a support part is provided at the bottom of the support column 6, the support part including a support pad 81 located below the rubber bearing, the support pad 81 being sleeved on the outside of the support column 6;

[0026] The pressure head 4 is controlled to descend by the installation part, which in turn drives the pressure head 4 to press the rubber bearing downward, so that the rubber bearing contacts the support pad 81, and then the rubber bearing is assembled in the lower part of the support column 6.

[0027] In this embodiment, the rubber bearing is assembled by the mounting part. During the component pressing process, while the pressure head 4 is kept horizontal, the rubber sleeve 9 continues to press down on other components. The rubber sleeve 9 can maintain the horizontal state at the initial pressing, ensuring that each component is subjected to uniform force throughout the assembly process. The pressure head 4 is vertically guided on the machine base 1 by the cylinder 3, which can ensure the pressure and horizontality of the pressure head 4. Thus, the assembly process is reasonable, stable, safe, reliable, and can also guarantee accuracy and quality.

[0028] like Figure 2 and Figure 3 As shown, a rubber bearing assembly mechanism is provided, wherein the support column 6 is fixedly installed by the limiting section 7 and the stepped section 8. The top edge of the limiting section 7 is chamfered. The stepped section 8 is detachably installed on the upper surface of the machine base 1 and is formed by the stacking of adjacent bosses. The support pad 81 is sleeved on the upper end of the stepped section 8.

[0029] In this process, the pressure head 4 continues to press down on the rubber jacket 9 until the bottom pad 94 contacts the top of the step section 8. Then, the rubber jacket 9 moves downward until the top pad 94 contacts the bottom pad 94. At this point, all the other product parts are inside the rubber jacket 9, except for the bottom pad 94.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, a rubber bearing assembly mechanism includes a floating support frame 82 in the support part. The floating support frame 82 is slidably installed in the positioning hole opened at the top of the stepped section 8. The floating support frame 82 is distributed around the bottom of the support pad 81. A compression spring 83 is fixedly connected to the end of the floating support frame 82. A stop screw 84 is provided at the bottom of the compression spring 83.

[0031] Preferably, there are at least three floating support frames 82.

[0032] In this embodiment, due to the elastic force, before the pressure head 4 presses down, the lowest pad 94 is in contact with the upper surface of the floating support frame 82. When the pressure begins to be pressed down, the compression spring 83 acts as a buffer to reduce the instantaneous force on the lower surface of the rubber sleeve 9 caused by the impact. The floating support frame 82 begins to move downward until the bottom pad 94 contacts the top of the step section 8. The floating support frame 82 maintains this position until the pressure head 4 moves upward. At this moment, the floating support frame 82 bounces upward, causing the lowest pad 94 to move upward into the rubber sleeve 9. At this time, the chamfered surface at the lower end of the rubber sleeve 9 returns to its normal state before deformation, and the assembly is completed.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, a rubber bearing assembly mechanism has an installation part connected to a machine base 1 via a guide. The guide is a vertical guide rail 2, and a pressure head 4 is slidably connected to the vertical guide rail 2. The installation part includes a cylinder 3 connected to the guide. The output end of the cylinder 3 is fixedly connected to the pressure head 4. A through hole 5 is provided inside the pressure head 4, and a support column 6 corresponds to the through hole 5. The diameter of the through hole 5 is larger than the top diameter of the support column 6.

[0034] In this embodiment, the pressure head 4 moves vertically on the machine base 1 via the cylinder 3, which ensures the pressure and levelness of the pressure head 4. During installation, the pressure head 4 presses against the rubber sleeve 9 and moves in the restricted section 7 of the support column 6 for assembly.

[0035] Working principle: In use, first, the upper and lower pads 94 and the outer ring of the spring 91 are fitted onto the limiting section 7 of the support column 6. The retainer 93 with the needle roller and the rubber sleeve 9 are placed on the top of the outer ring of the spring 91. The press head 4 moves vertically on the machine base 1 through the cylinder 3. When the through hole 5 in the press head 4 passes through the support column 6, the press head 4 begins to contact the rubber sleeve 9 and moves it downward. Then, the other product parts below will also move downward until the bottom pad 94 contacts the step section 8. Then the press head 4 continues to press down the rubber sleeve 9 and moves it downward, while the other product parts below it do not move. The rubber sleeve 9 moves until the top pad 94 contacts it. At this time, except for the bottom pad 94, all the other product parts are inside the rubber sleeve 9.

[0036] Due to the elastic force, before the pressure head 4 presses down, the lowest pad 94 is in contact with the support pad 81 on the floating support frame 82. When the pressure begins to fall, the compression spring 83 acts as a buffer to reduce the impact force on the lower end of the rubber sleeve 9. The floating support frame 82 begins to move downward until the lower pad contacts the top of the step section 8. The floating support frame 82 remains in this position until the pressure head 4 moves upward. At this moment, the floating support frame 82 bounces upward, causing the lowest pad 94 to move upward into the rubber sleeve 9. At this time, the chamfered surface at the lower end of the rubber sleeve 9 returns to its normal state before deformation, and the assembly is completed.
