Description

Technical Field

[0001] This utility model relates to the field of bearing press-fitting machines, and in particular to a pneumatic bearing press-fitting machine. Background Technology

[0002] Bearings are key components used to support rotating mechanical parts and are commonly used in various industrial equipment, automotive, aerospace, and other mechanical systems. The function of bearings is to reduce friction, support and position rotating shafts, and enable mechanical parts to operate smoothly. During the assembly process of bearings, due to repeated hammering and the extrusion pressure on the bearing under uneven assembly conditions, stress concentration occurs, and the inner ring, outer ring, and rolling elements of the bearing can easily deform, causing friction during bearing operation and ultimately affecting the service life of the bearing components. Therefore, it is particularly important to ensure that the bearing and the assembly shaft conform to the standards during the bearing press-fitting process.

[0003] In daily life, when bearings need to be installed on shaft parts, they are generally installed manually by tapping. A copper rod is placed tightly against the end face of the bearing's inner ring, and a hand hammer is used to directly tap the copper rod. The force is transmitted through the copper rod, and the bearing is slowly installed onto the shaft. If the bearing's inner ring is large, the copper rod can be used to tap evenly around the end face of the bearing's inner ring, avoiding tapping only one side or using excessive force to prevent misalignment or cracking of the bearing. A sleeve can also be used, pressing the sleeve directly onto the bearing's end face and tapping it with a hand hammer to distribute the pressure evenly across the entire end face of the ring. However, this type of press-fitting device lacks precision, easily leading to bearing deformation, coaxiality deviation, and a high scrap rate. Moreover, the press-fitting process is inefficient, has a high operational risk factor, and requires high labor intensity for workers, making it unsuitable for mass production.

[0004] Later, an automatic bearing press-fitting machine appeared on the market. It uses a positioning fixture structure, an automatic feeding structure, an automatic feeding mechanism, and an automatic press-fitting device to realize the operation of the machine driven by cylinders and motors, and achieve automated assembly. However, due to the lack of a correction mechanism, this type of automatic bearing press-fitting machine is unable to ensure the precise coaxiality of the bearing with the shaft or bearing housing during the installation process. The misaligned installation of the bearing will cause uneven force on the rolling elements inside the bearing, resulting in excessive pressure in some areas, accelerating bearing wear, and shortening its service life.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a pneumatic bearing press machine. Through the design of a feeding device, a pressing mechanism and a pressing floating device, the pressing floating device includes at least a correction mechanism and a fixing block. The fixing block is provided with a correction groove, so that the parts can be finely adjusted and corrected relative to the correction groove during the pressing process, thereby reducing product deviation and unloading during press-fitting.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

A high-precision linear guide rail is used to ensure the accuracy of the bearing after interference fit.

[0013] As a preferred embodiment, the clamping mechanism includes a first clamping mechanism and a second clamping mechanism, which are symmetrically arranged on the left and right sides of the correction mechanism; the feeding device includes a first feeding device and a second feeding device, which are symmetrically arranged above the first clamping mechanism and the second clamping mechanism.

The second driving device controls the push rod to reciprocate left and right toward the connecting channel to convey the press-fit parts in the connecting channel to the output channel, thereby realizing automatic feeding of bearings without the need for manual installation and feeding, reducing the operational risk factor and improving production efficiency.

[0015] As a preferred embodiment, both the first clamping mechanism and the second clamping mechanism further include a mounting base, and the first clamping mechanism and the second clamping mechanism are mounted and positioned on the base via the mounting base.

Specifically, as can be seen from the above technical solution, it mainly uses the design of a feeding device, a pressing mechanism, and a pressing floating device. The pressing floating device includes at least a correction mechanism and a fixed block. The fixed block is provided with a correction groove. In this way, the feeding device feeds the material and flows it to the pressing guide sleeve of the pressing mechanism. The first driving device controls the pressing guide sleeve to press against the part on the fixed block, so that the part is finely adjusted and corrected relative to the correction groove during the pressing process, reducing product deviation and unloading during pressing, so that the bearing can be accurately installed in the predetermined position, thereby improving the pressing accuracy and avoiding uneven bearing force and unstable operation caused by coaxiality deviation.

[0045] A pneumatic bearing press machine includes a base 10, a feeding device 20, and a pressing floating device 30.

[0046] The feeding device 20 and the pressing floating device 30 are mounted on the base 10. The feeding device 20 is used to transport the bearing 50, and the pressing floating device 30 is used to press the bearing 50 onto the part 60 and perform centering correction during pressing. Preferably, the base 10 is also provided with a support frame 11, and the control device 40 and the feeding device 20 are mounted and positioned on the support frame 11.

[0047] The output end of the feeding device 20 is connected to the clamping guide sleeve 321. The feeding device 20 includes a first feeding device and a second feeding device, which are symmetrically arranged above the first clamping mechanism and the second clamping mechanism. The dual-station design allows it to process both ends of the part 60 at the same time, thereby improving processing efficiency.

[0048] Preferably, both the first and second feeding devices include a storage component 21, a connecting channel 22, a push rod 23, a second driving device 24, and a conveying channel 25. The output end of the storage component 21 is connected to the connecting channel 22, the output end of the connecting channel 22 is connected to the input end of the output channel, and the output end of the output channel is connected to the pressing guide sleeve 321.

The second driving device 24 controls the push rod 23 to reciprocate left and right toward the connecting channel 22 to convey the press-fitted parts 60 in the connecting channel 22 to the output channel, thereby realizing automatic feeding of the bearing 50 without manual installation and loading, reducing the operational risk factor and improving production efficiency. Preferably, the second driving device 24 is a cylinder.

[0049] The pressing floating device 30 includes at least a correction mechanism 31 and a pressing mechanism 32. The correction mechanism 31 includes at least a sliding component 33 and a fixing block 34 mounted on the sliding component 33 for placing the part 60. The fixing block 34 is provided with a correction groove 341. Preferably, the sliding component 33 includes a linear guide rail 331, a slider 332 and a mounting plate 333. The linear guide rail 331 extends in the left-right direction. The slider 332 can move along the extension direction of the linear guide rail 331. The mounting plate 333 is connected to the slider 332. The fixing block 34 is disposed on the mounting plate 333. A high-precision linear guide rail 331 is used to ensure the accuracy of the bearing 50 after interference fit.

[0050] The clamping mechanism 32 is disposed on one side of the correction mechanism 31. The clamping mechanism 32 includes at least a clamping guide sleeve 321 disposed on the side facing the fixing block 34 and a first driving device 322 connected to the clamping guide sleeve 321. The first driving device 322 controls the clamping guide sleeve 321 to reciprocate left and right, so that the part 60 is finely adjusted and corrected relative to the correction groove 341 during the clamping process. Preferably, the first driving device 322 is a cylinder.

[0051] Preferably, the clamping mechanism 32 includes a first clamping mechanism and a second clamping mechanism, which are symmetrically arranged on the left and right sides of the correction mechanism 31. Preferably, both the first and second clamping mechanisms also include a mounting base 323, which mounts and positions the first and second clamping mechanisms on the base 10. The first and second clamping mechanisms have the same structure.

[0052] Preferably, the pneumatic bearing 50 press-fitting machine further includes a control device 40, which is electrically connected to the correction mechanism 31, the pressing mechanism 32, and the feeding device 20. The control device 40 includes at least a display screen, a start button, and a safety light curtain. The start button controls the start and stop of the pressing floating device 30. In actual use, when a worker makes an error, the safety light curtain will detect it immediately and stop the equipment, ensuring efficient and safe production. This display screen, start button, and safety light curtain are all well-known technologies in the art and will not be described in detail here.

[0053] The general working principle of this embodiment is described in detail below:

[0054] The operator loads and unloads the parts. The part 60 to be pressed into the bearing 50 is placed on the fixing block 34. At this time, there is a gap between the part 60 to be pressed into the bearing 50 and the correction groove 341 (e.g., Figure 6 (As shown), then the bearing 50 is conveyed into the connecting channel 22 through the output end of the storage component 21. The second drive device 24 controls the push rod 23 to move towards the connecting channel 22, so as to convey the press-fit part 60 in the connecting channel 22 to the output channel, so that the bearing 50 slides towards the clamping guide sleeve 321. Then, by turning on the start button, the first drive device 322 controls the clamping guide sleeve 321 to move linearly towards the fixed block 34 to clamp. During the clamping process, this part of the thrust will make the part 60 fine-tune and correct relative to the correction groove 341 (e.g., Figure 7 As shown), the fixed block 34 moves relative to the linear guide rail 331. After the pressing is completed, the push rod 23 will not push the material after the equipment stops running by turning off the start button. The pressing guide sleeve 321 will move away from the pressed part 60 under the drive of the drive device, thereby taking out the pressed part 60.

[0055] The key design feature of this invention lies in its design of a feeding device, a pressing mechanism, and a pressing floating device. The pressing floating device includes at least a correction mechanism and a fixed block. The fixed block is provided with a correction groove. In this way, the feeding device feeds the material to the pressing guide sleeve of the pressing mechanism. The first driving device controls the pressing guide sleeve to press against the part on the fixed block. This allows the part to be finely adjusted and corrected relative to the correction groove during the pressing process, reducing product deviation and unloading during pressing. This ensures that the bearing can be accurately installed in the predetermined position, thereby improving the pressing accuracy and avoiding uneven bearing force and unstable operation caused by coaxiality deviation.

[0056] Secondly, automated assembly is achieved through feeding devices, clamping mechanisms, and clamping floating devices, enabling the automatic flow of bearing press-fitting from feeding to processing completion. This makes operation convenient, resulting in high efficiency and low labor intensity.

[0057] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
