Description

Technical Field

[0001] This utility model relates to the field of bearing application technology, and in particular to an automatic centering and pressing device for bearing assembly. Background Technology

[0002] In the field of machinery manufacturing, bearings are essential components, widely used in various mechanical equipment. The assembly quality of bearings directly affects the performance and service life of mechanical equipment. During bearing assembly, the bearing needs to be accurately pressed into the bearing housing of the workpiece to be assembled, which requires good alignment between the bearing and the workpiece.

[0003] Currently, traditional bearing assembly methods mostly rely on manual operation. This involves manually aligning the bearing with the bearing housing of the workpiece to be assembled, and then using a press to force the bearing in. This assembly method is not only labor-intensive and inefficient, but it also makes it difficult to ensure the alignment between the bearing and the workpiece, easily leading to problems such as misalignment and damage, thus affecting product quality.

[0004] Although there are some automated bearing assembly equipment, these devices have low centering accuracy, complex structure, inconvenient operation, and high maintenance costs, making it difficult to meet the needs of actual production. Therefore, this utility model proposes an automatic centering and pressing device for bearing assembly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automatic centering and pressing device for bearing assembly, which can realize the automatic centering of the bearing and the workpiece to be assembled, improve the accuracy and efficiency of bearing assembly, and reduce labor intensity.

[0006] To solve the above-mentioned technical problems, the present invention provides an automatic centering and pressing device for bearing assembly, including a mounting plate, wherein a centering mechanism is bolted to the mounting plate near the bottom position to clamp and center continuously bearing components. The top of the mounting plate is bolted with a pressing mechanism to press in the centered and fixed bearing components.

[0007] The present invention is further configured such that: the mounting plate is L-shaped, and the bending part is bolted to both sides with reinforcing plates.

[0008] The above technical solution facilitates the use of reinforcing plates to reinforce the entire mounting plate, ensuring its stability and firmness during use.

[0009] The present invention is further configured such that: the centering mechanism includes a drive cylinder bolted to the mounting plate; a push block is bolted to the end face of the drive rod of the drive cylinder; the push block is movably connected to two symmetrically arranged centering clamping blocks; a rotating shaft is engaged with each of the two centering clamping blocks near the center; an auxiliary block is rotatably connected to each of the two rotating shafts; and the two auxiliary blocks are symmetrically bolted to both sides of the mounting plate.

[0010] The above technical solution activates the drive cylinder, which in turn drives the push block to move. The push shaft on the push block slides in the movable groove of the centering clamp block, thereby causing the two centering clamp blocks to rotate around the center of the rotation axis, thus achieving the clamping and centering of the bearing.

[0011] The present invention is further configured such that: the top of the push block is symmetrically and fixedly connected with push shafts near both ends, and the two push shafts are respectively slidably connected to the movable grooves opened on the end faces of the two centering clamping blocks.

[0012] The above technical solution facilitates the sliding of the push shaft inside the movable groove when the push block is driven, thereby driving the two centering clamps to rotate.

[0013] The present invention is further configured such that the inner walls of the two centering clamps are both arc-shaped and each has a toothed hole in the middle, and the toothed block is fixedly connected to the top of the rotating shaft through the toothed hole.

[0014] The above technical solution facilitates the installation of the centering clamp, allowing for appropriate connection and fixation using toothed holes and toothed blocks according to the bearing dimensions, thereby improving the flexibility of adjustment during use.

[0015] The present invention is further configured such that: the pressing mechanism includes a fixing plate bolted to the top of the mounting plate, a pressing cylinder bolted to the top of the fixing plate, and a pressing block fixedly connected to the end face of the drive rod of the pressing cylinder.

[0016] Using the above technical solution, the pressing cylinder is activated, and the driving rod of the pressing cylinder drives the pressing block to move downward, pressing the aligned bearing into the bearing seat of the workpiece to be assembled, thus completing the assembly of the bearing.

[0017] The present invention is further configured such that the pressing block is shaped like a frustum.

[0018] Through the above technical solution, the frustum-shaped press-in block can better contact the bearing components during the pressing process, resulting in a more uniform pressure distribution and preventing damage to the bearing components due to excessive localized force. At the same time, the frustum-shaped structure also helps guide the bearing components accurately into the installation position of the workpiece to be assembled, improving the pressing accuracy.

[0019] The beneficial effects of this utility model are as follows: 1. The automatic centering and pressing device for bearing assembly proposed in this utility model can realize the automatic centering of the bearing and the workpiece to be assembled by setting a centering mechanism, which improves the accuracy of bearing assembly, avoids problems such as assembly skewing and damage caused by manual operation, and ensures product quality.

[0020] 2. This utility model automates the bearing assembly process, reduces manual intervention, lowers the labor intensity of workers, and improves production efficiency, thus meeting the needs of large-scale production.

[0021] 3. The present invention has a reasonable and simple structural design, reliable connection between components, convenient operation, and low maintenance cost. It has strong practicality and economy, and is easy to promote and apply in actual production.

[0022] 4. The pressing mechanism of this utility model uses a cylinder as a power source, which provides stable pressure and can smoothly press the bearing into the workpiece to be assembled, thereby improving the assembly quality and preventing the pressing head from shifting during the movement.

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0026] like Figures 1-5As shown, an automatic centering and pressing device for bearing assembly includes a mounting plate 1, which is L-shaped. Reinforcing plates 11 are bolted to both sides of the bent portion of the mounting plate 1 to reinforce its position and ensure stability during use. A centering mechanism 2 is bolted to the bottom of the mounting plate 1 to clamp and center continuously bearing components. The centering mechanism 2 includes a drive cylinder 21 bolted to the mounting plate 1. Push blocks 22 are bolted to the end face of the drive rod of the drive cylinder 21. Push shafts 221 are symmetrically fixed to the top of the push blocks 22 near both ends. The two push shafts 221 are slidably connected to the movable grooves 231 on the end faces of two centering clamping blocks 23, respectively. This allows the push blocks 22 to slide within the movable grooves 231 when driven, thereby rotating the two centering clamping blocks 23. The centering clamps 23 are symmetrically connected to the bearing. The inner walls of the two centering clamps 23 are arc-shaped and each has a toothed hole 232 in the middle. The toothed block 241 is fixedly connected to the top of the rotating shaft 24 through the toothed hole 232. This allows the centering clamps 23 to be properly connected and fixed according to the size of the bearing by using the toothed hole 232 and the toothed block 241, which improves the flexibility of adjustment during use. The rotating shaft 24 is engaged with the two centering clamps 23 near the middle. The two rotating shafts 24 are rotatably connected to the auxiliary blocks 25 respectively. The two auxiliary blocks 25 are symmetrically bolted to both sides of the mounting plate 1. When the drive cylinder 21 is activated, the drive rod of the drive cylinder 21 drives the push block 22 to move. The push shaft 221 on the push block 22 slides in the movable groove 231 of the centering clamp 23, thereby driving the two centering clamps 23 to rotate around the center of the rotating shaft 24, so as to clamp and center the bearing.

[0027] like Figure 1 and Figure 2 As shown, a pressing mechanism 3 is bolted to the top of the mounting plate 1 to press in the aligned and fixed bearing parts. The pressing mechanism 3 includes a fixing plate 31 bolted to the top of the mounting plate 1. A pressing cylinder 32 is bolted to the top of the fixing plate 31. A pressing block 33 is fixedly connected to the end face of the drive rod of the pressing cylinder 32. When the pressing cylinder 32 is activated, the drive rod of the pressing cylinder 32 drives the pressing block 33 to move downward, pressing the aligned bearing into the bearing seat of the workpiece to be assembled, thus completing the assembly of the bearing. The pressing block 33 is shaped like a frustum, which facilitates the pressing operation of bearings of different sizes using the frustum-shaped pressing block 33.

[0028] In use, the bearing to be assembled is first placed between two centering clamps 23. The drive cylinder 21 is then activated, its drive rod driving the push block 22. The push shaft 221 on the push block 22 slides within the movable groove 231 of the centering clamps 23, thereby causing the two centering clamps 23 to rotate around the rotating shaft 24, achieving clamping and centering of the bearing. After centering, the pressing cylinder 32 is activated, its drive rod driving the pressing block 33 downwards, pressing the centered bearing into the bearing seat of the workpiece to be assembled, completing the bearing assembly. After assembly, the drive cylinder 21 and pressing cylinder 32 are reset, ready for the next assembly operation.
