[0033] In order to solve the above problems, the present application provides a bearing riveting and pressing tool 100.

[0034] Please refer to Figures 1 to 4 In an embodiment of the present application, the bearing riveting and pressing tool 100 is used in cooperation with an oil press, and the oil press comprises an upper plate and a lower plate arranged oppositely;

[0035] The bearing riveting and pressing tool 100 comprises:

[0036] The mounting plate 1 is mounted on the lower plate and is provided with a positioning part 2 for positioning the gear box 200;

[0037] The moving plate 3 is drivingly connected to the upper plate and is arranged in a spaced manner with the mounting plate 1, and the moving plate 3 is provided with a riveting head 4 on the side facing the mounting plate 1, the riveting head 4 is arranged towards the positioning part 2, and the riveting head 4 is used for riveting the bearing 300 in the gear box 200;

[0038] The guide assembly 5 connects the mounting plate 1 and the moving plate 3.

[0039] In the embodiment, the oil press can include a fixed lower plate and an upper plate that can move up and down, and the upper plate is driven by a hydraulic assembly to move vertically. The oil press can provide a stable frame structure for the bearing riveting and pressing tool 100, so as to ensure that it can withstand a large pressure without deformation or displacement when riveting the bearing 300 in the gear box 200, thereby improving the production efficiency and product quality of the bearing 300.

[0040] The bearing riveting tool 100 can include a mounting plate 1, a moving plate 3 and a guide assembly 5; wherein:

[0041] The mounting plate 1 is fixed on the lower plate of the oil press as the mounting bottom plate of the bearing riveting tool 100. The positioning part 2 is arranged on the mounting plate 1 for accurately fixing the position of the gear box 200, so as to ensure the accurate positioning of the bearing 300 in the gear box 200, reduce the risk of poor riveting caused by position deviation, and improve the flatness and consistency of the bearing 300.

[0042] The moving plate 3 is connected to the upper plate of the oil press as the mounting plate 1 of the riveting head 4, and is arranged in a spaced and opposite manner with the mounting plate 1. The riveting head 4 of a specific shape and size is assembled on the side of the moving plate 3 facing the mounting plate 1. The riveting head 4 is arranged towards the positioning part 2 for directly acting on the bearing 300 in the gear box 200 when the gear box 200 is placed on the positioning part 2. That is, the riveting head 4 is arranged opposite to the positioning part 2, which can provide an accurate force point and direction for the riveting operation of the riveting head 4, so as to ensure effective and uniform riveting of the bearing 300, and avoid damage to the bearing 300 caused by improper force.

[0043] The guide assembly 5 connects the mounting plate 1 and the moving plate 3, such as guide columns 51, guide sleeves and other mechanical elements to guide the linear motion of the moving plate 3. By arranging the guide assembly 5, the stability and flatness of the moving plate 3 can be enhanced, and the accuracy and reliability of the riveting process are further ensured.

[0044] The technical scheme of the utility model discloses a bearing riveting tool 100 used in cooperation with the oil press, which comprises a mounting plate 1 and a moving plate 3. The mounting plate 1 is fixed on the lower plate of the oil press and is provided with a positioning part 2 for accurate positioning of the gear box 200, so as to ensure accurate positioning of the bearing 300 during the riveting process and reduce the risk of position deviation. The moving plate 3 is drivingly connected to the upper plate of the oil press and is spaced apart from the mounting plate 1. The moving plate 3 is provided with a riveting head 4 on the side facing the mounting plate 1. The riveting head 4 is arranged opposite to the positioning part 2 and is specially designed for accurate riveting operation of the bearing 300 in the gear box 200. In addition, the mounting plate 1 and the moving plate 3 are connected by the guide assembly 5, which can ensure the linearity and stability of the moving plate 3, further improve the riveting accuracy, and avoid damage to the bearing 300 caused by uneven or unstable force. Through the above design, the production quality of the bearing 300 can be improved, the flatness of the bearing 300 can meet the requirements, the production efficiency can be improved, and the problems of unstable quality and low efficiency in the original process can be solved.

[0045] Please refer to Figure 2In an embodiment of the present application, the installation plate 1 is provided with a positioning column on the side facing the moving plate 3, and the positioning column is the positioning part 2.

[0046] In the embodiment, the positioning column is a specific implementation form of the positioning part 2, which is arranged on the installation plate 1 and faces the side of the moving plate 3. The positioning column is used to match the gear box 200, so as to ensure that the gear box 200 can be accurately positioned on the riveting position during riveting operation. By arranging the positioning column, high-precision positioning of the gear box 200 and the bearing 300 in the riveting process can be realized, effectively avoiding the problems of bearing 300 deviation or damage caused by inaccurate positioning. Moreover, accurate positioning can reduce the adjustment time and trial-and-error times of the gear box 200, so that each assembly can be quickly and accurately completed, thereby improving the production efficiency of the bearing 300.

[0047] Please refer to Figure 2 In an embodiment of the present application, the positioning column is provided with a plurality of positioning columns, and the plurality of positioning columns are arranged side by side in the middle of the installation plate 1.

[0048] In the embodiment, the positioning column is provided with a plurality of positioning columns, which means that not only one positioning column is used to position the gear box 200, but also a plurality of positioning columns are used. By using a plurality of positioning columns, the positioning stability and accuracy of the gear box 200 on the installation plate 1 can be significantly improved. Compared with a single positioning point, a plurality of positioning points can more effectively prevent deviation, especially when pressure is applied.

[0049] The plurality of positioning columns are arranged side by side along the width direction of the installation plate 1 and located in the middle position of the installation plate 1. When the gear box 200 is placed along the width direction of the installation plate 1, the force applied to the gear box 200 can be more evenly distributed, reducing the risk of deformation or damage caused by local stress concentration, and being beneficial to maintaining the good state of the bearing 300.

[0050] Please refer to Figure 2 In an embodiment of the present application, the guide assembly 5 includes a plurality of guide columns 51, and the plurality of guide columns 51 are arranged at intervals on the installation plate 1. The moving plate 3 is provided with a guide hole 301 corresponding to the position of each guide column 51.

[0051] In this embodiment, multiple guide columns 51 are fixed on the mounting plate 1 and distributed at certain intervals. By positioning and guiding the moving plate 3 through the guide columns 51, the consistency of the moving plate 3 and the mounting plate 1 in the center distance can be ensured, and the positioning error can be reduced. On the moving plate 3, a corresponding guide hole 301 is provided for the position of each guide column 51. When the oil press drives the moving plate 3 to move downward for riveting operation, the guide hole 301 will slide along the guide column 51, ensuring that the movement track of the moving plate 3 is accurate and stable. Through the cooperation of the guide column 51 and the guide hole 301, the moving plate 3 can maintain linearity during the up and down movement, avoiding any possible deviation or swing, and ensuring that the riveting head 4 can accurately act on the bearing 300.

[0052] Please refer to Figure 2 In an embodiment of the present application, the guide assembly 5 further comprises multiple anti-friction members 52, and the multiple anti-friction members 52 are one-to-one arranged in the multiple guide holes 301. Each anti-friction member 52 is provided with a guide passage 501 for the guide column 51 to pass through.

[0053] In this embodiment, the anti-friction member 52 is used to reduce the direct contact and friction between the guide column 51 and the guide hole 301. The anti-friction member 52 can be made of wear-resistant material to improve durability and reduce friction coefficient. Each anti-friction member 52 is provided with a guide passage 501, which allows the guide column 51 to pass through freely while maintaining a close fit to ensure the accuracy and stability of the moving plate 3 during movement.

[0054] Please refer to Figure 2 In an embodiment of the present application, the anti-friction member 52 is interference fitted in the corresponding guide hole 301. Interference fitting means that the size of the anti-friction member 52 is slightly larger than the size of the guide hole 301 it is to be installed in. By applying a certain pressure or using appropriate tools (such as cold shrinkage, thermal expansion, etc.), the anti-friction member 52 is forcibly assembled into the guide hole 301. Interference fit can ensure that the anti-friction member 52 is tightly fixed in the guide hole 301, avoiding displacement or falling of the anti-friction member 52 during use, and ensuring that the guide column 51 can smoothly slide in the guide passage 501, thereby maintaining high-precision linear motion. Since the anti-friction member 52 is stable and immovable, it can ensure that the guide column 51 moves along the same path each time, reducing errors caused by relative displacement between parts and improving the consistency of riveting operation.

[0055] Please refer to Figure 2 In an embodiment of the present application, the anti-friction member 52 is an oil-free bushing.

[0056] In the embodiment, the oil-free bushing is a self-lubricating bushing, which is usually made of a composite material containing solid lubricant. The bushing can provide low friction coefficient and good wear resistance without additional lubricating oil. The oil-free bushing is installed in the guide hole 301 of the moving plate 3 with interference, and is provided with a guide channel 501 for the guide column 51 to pass through. Since the oil-free bushing has self-lubricating properties, it can provide a stable low-friction surface, so that the guide column 51 can smoothly slide inside it, ensuring the smoothness and accuracy of the movement of the moving plate 3, thereby improving the efficiency and quality of the entire riveting process.

[0057] Please refer to Figure 2 In an embodiment of the utility model, the guide assembly 5 further includes a limiting column 53, the limiting column 53 is arranged on the mounting plate 1 and is located between the mounting plate 1 and the moving plate 3, and the limiting column 53 is used for limiting the moving plate 3.

[0058] In the embodiment, the limiting column 53 is arranged on the mounting plate 1 and is located between the mounting plate 1 and the moving plate 3. The position and height of the limiting column 53 are designed according to the process requirements of the bearing 300 to ensure that the movement of the moving plate 3 can be stopped in time during the downward movement to prevent excessive downward movement from causing damage to the equipment or the workpiece. That is, the limiting column 53 can ensure the pressing height of the moving plate 3 to avoid the problem of excessive pressing that damages the bearing 300 and the gear box 200, thereby ensuring stable pressing quality. Moreover, by accurately setting the height of the limiting column 53, the exact position of the pressing force applied by the riveting head 4 can be controlled, thereby ensuring the consistency and accuracy of each riveting operation, which is crucial for ensuring the quality of the bearing 300.

[0059] In addition, the limiting column 53 can be fixed or adjustable to facilitate adjustment according to the requirements of different workpieces.

[0060] Please refer to Figure 2 In an embodiment of the utility model, the limiting column 53 is provided with a plurality of limiting columns 53, and the plurality of limiting columns 53 and the plurality of guide columns 51 are staggered on the mounting plate 1.

[0061] In the embodiment, instead of using only one limiting column 53 to limit the downward movement distance of the moving plate 3, a plurality of limiting columns 53 are distributed on the mounting plate 1. In this way, on the one hand, more balanced support and limitation can be provided to ensure that the movement of the moving plate 3 in the entire working area can be effectively controlled, and on the other hand, multiple-point limitation can be provided to ensure that even if one limiting column 53 fails, the other limiting columns 53 can still play a protective role to prevent the moving plate from excessive downward movement, thereby increasing the safety factor of the operation.

[0062] The plurality of limiting columns 53 and the plurality of guide columns 51 are staggered arranged along the circumference of the mounting plate 1. This means that they are not simply arranged in a row or a column, but are scattered and distributed in a staggered manner on the mounting plate 1. For example, if the mounting plate 1 is viewed from above, it can be seen that the guide columns 51 and the limiting columns 53 are arranged alternately, forming a uniform distribution state. The staggered arrangement helps to ensure that the moving plate 3 moves more smoothly up and down, reducing the possibility of vibration and swing, so as to ensure that the riveting head 4 can accurately act on the target position, improving the machining precision.

[0063] The utility model discloses still a bearing riveting equipment, please refer to Figures 1 to 4 The bearing riveting equipment includes the oil press and bearing riveting frock 100, and the specific structure of bearing riveting frock 100 refers to the above embodiment, because the bearing riveting equipment of the utility model adopts all the technical schemes of the above all embodiments, so at least has all the beneficial effects brought by the technical scheme of the above embodiment, here will not repeat.

[0064] Among them, the oil press includes the upper plate and the lower plate opposite. The upper plate connects the moving plate 3 of bearing riveting frock 100, can drive moving plate 3 to exert pressure downward and riveting operation. The lower plate is installed with the mounting plate 1 of bearing riveting frock 100, provides basic support for the whole machining process.

[0065] For the convenience of understanding the assembly of bearing riveting equipment, the assembly process is introduced as follows:

[0066] The first step is to prepare the moving plate 3: first, install the riveting head 4 on the moving plate 3 using the first fixing part 61, then assemble the anti-friction part 52 to the corresponding guide hole 301 of the moving plate 3, and then use the second fixing part to pre-tighten the moving plate 3 to the upper plate of the oil press, realizing mechanical transmission;

[0067] The second step is to assemble the mounting plate 1: first, insert and fix the guide column 51 in the mounting plate 1, then use the third fixing part 63 to fix the positioning column on the mounting plate 1, then use the fourth fixing part 64 to fix the limiting column 53 on the mounting plate 1, and finally use the fifth fixing part to fix the mounting plate 1 to the lower plate of the oil press;

[0068] The third step is adjustment and final fixation: first, adjust the height of the upper plate of the oil press, so that the moving plate 3 and the mounting plate 1 of the bearing riveting frock 100 can perfectly fit together, then use the anti-friction part 52 and the guide column 51 to fine-tune the center distance, ensure the alignment between the parts, and after determining the correct position, tighten the second fixing part to completely fix the moving plate 3 on the upper plate of the oil press, complete the whole assembly process.

[0069] Through the assembly process, the precise fit between the oil press and the bearing riveting tool 100 can be ensured, so that the bearing 300 will not be offset or damaged during the pressing process, and the production efficiency and quality are improved.

[0070] Similarly, for the convenience of understanding how the bearing riveting equipment works, the working process of the bearing riveting equipment is introduced as follows:

[0071] After the bearing riveting tool 100 and the oil press are assembled, the oil press sets the pressing height and the pressing speed; after the parameter setting is completed, the gear box 200 with the bearing 300 is placed on the mounting plate 1, and the gear box 200 is fixed through the positioning column; after the operator presses the start button of the bearing riveting equipment, the oil press starts to work and drives the moving plate 3 to move towards the mounting plate 1, that is, the moving plate 3 moves downward; as the moving plate 3 descends, the riveting head 4 on it exerts pressure on the gear box 200, so that the bearing 300 in the gear box 200 is fixed in place by extrusion deformation; once the preset pressing height is reached, the oil press will automatically pull the moving plate 3 back to the initial position, completing the riveting process; the operator can take the gear box 200 that has completed riveting from the mounting plate 1 and prepare for the next bearing 300 processing.

[0072] During the entire working process of the bearing riveting equipment, the bearing riveting tool 100 can provide precise positioning fit and height limiting function, so that the consistency and accuracy of each bearing 300 riveting operation are ensured, the quality consistency of the bearing 300 product is effectively guaranteed, and the production yield is improved.
