Description

Technical Field

[0001] This utility model relates to the field of bearing housing press-fitting technology, and in particular to a bearing housing press-fitting device. Background Technology

[0002] In modern industrial production, idlers are key components of various conveying equipment such as belt conveyors, and their quality and performance directly affect the operating efficiency, stability, and service life of the conveying system. The assembly quality of the idlers, especially the concentricity of the bearing housings at both ends, is a crucial factor in ensuring smooth, low-noise, and long-life operation. Among these processes, the pressing of the bearing housings is one of the core steps in idler production, and its precision directly determines the installation state of the bearings and the rotational accuracy of the idler.

[0003] However, in the existing idler roller bearing housing press-fitting process, due to the lack of effective constraint on the guiding device during press-fitting, the guiding device cannot remain stable as the bearing housing gradually enters the idler roller tube, causing a sudden change in the stress state of the press-fitting head as it approaches its final position. At the instant the press-fitting head is fully in place, the pressure increases dramatically. This sudden change in pressure causes uneven stress on the press-fitting head, resulting in head tilting. The direct consequence is a significant deviation in the concentricity of the bearing housings at both ends of the idler roller, affecting the assembly quality and overall performance of the idler roller. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the existing idler roller bearing housing press-fitting process, due to the lack of effective constraint on the guiding device during the press-fitting process, as the bearing housing gradually enters the idler roller tube, the guiding device cannot maintain stability, resulting in uneven force on the press-fitting head, causing the head to tilt, which leads to a large deviation in the concentricity of the bearing housings at both ends of the idler roller, affecting the assembly quality and overall performance of the idler roller.

Detailed Implementation

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] like Figures 1 to 3 , Figure 5 As shown, this utility model provides a bearing housing press-fitting device, including a machine tool 1, a slide mechanism 2, a locking mechanism 3, and two press-fitting mechanisms 4.

[0036] Machine tool 1 serves as the basic structure of the entire equipment, providing an installation platform and rigid support; the slide mechanism 2 includes two slide units 21 and a first drive unit 22. The two slide units 21 are arranged opposite to each other on the machine tool 1, and the slide mechanism 2 is slidably mounted on the machine tool 1. The first drive unit 22 is connected to the two slide units 21 to drive the two slide units 21 to move towards or away from each other. By adjusting the horizontal position of the slide units 21, it can adapt to workpieces of different lengths. The slide mechanism 2 has multiple notches 23.

[0037] The locking mechanism 3 includes a first driving member 31, a lever arm 32, and a pressure block 33. The pressure block 33 is movably installed in the corresponding notch 23. The lever arm 32 is installed on the side of the slide unit 21. The first driving member 31 is installed on the slide mechanism 2 and connected to the lever arm 32 to drive the lever arm 32 to squeeze the pressure block 33 and press the pressure block 33 onto the machine tool 1, thereby fixing the slide unit 21 to the machine tool 1.

[0038] The pressing mechanism 4 includes a base 41, a pressing head unit 42, and a second drive unit 43. The base 41 is mounted on the corresponding slide unit 21. The pressing head unit 42 and the second drive unit 43 are mounted on the base 41, and the pressing head unit 42 is slidably connected to the base 41. The second drive unit 43 is connected to the pressing head unit 42 to drive the pressing head unit 42 away from or closer to another pressing head unit 42, thereby realizing the axial pressing action of the bearing seat.

[0039] Based on the above structure, after the first drive unit 22 drives the two slide units 21 to move to the designated position, the two ends of the workpiece are placed on the two slide units 21 respectively, and the bearing seat is placed on the corresponding press head unit 42. At this time, the locking mechanism 3 locks the slide unit 21 on the machine tool 1 through the force-increasing arm 32 and the pressure block 33. Then the second drive unit 43 drives the press head unit 42 to push the bearing seat into the designated position in the workpiece to complete the press fitting.

[0040] In this embodiment, the locking mechanism 3 remains locked throughout the pressing process, ensuring a tight fit between the slide unit 21 and the machine tool 1, preventing free movement. This effectively prevents the slide unit 21 from tilting due to a sudden surge in pressure during pressing, thus ensuring a smooth and reliable pressing process. It also avoids significant deviations in the concentricity of the bearing seats at both ends of the workpiece, which could affect the assembly quality and overall performance of the rollers. Furthermore, when the workpiece specifications change, the locking mechanism 3 can be unlocked, allowing the slide unit 21 to move freely on the machine tool 1. This allows the equipment to be flexibly adjusted according to the new workpiece specifications, adapting to diverse production needs.

[0041] Understandably, each slide unit 21 is provided with four locking mechanisms 3 to lock the four corners of the slide unit 21.

[0042] like Figure 3As shown, the lever arm 32 includes a cam structure 321 and a lever arm structure 322. The cam structure 321 is a part with a specific profile, such as an eccentric wheel or a wedge surface, used to convert rotational motion into vertical pressure. The lever arm structure 322 is a lever arm connected to one end of the cam structure 321, and the end of the lever arm structure 322 away from the cam structure 321 is hinged to one end of the first drive member 31. The other end of the first drive member 31 is hinged to the slide unit 21, forming a three-point support structure. When the lever arm 32 rotates relative to the horizontal direction and the cam structure 321 presses the pressure block 33, the pressure block 33 is pressed onto the machine tool 1.

[0043] In this embodiment, the first driving member 31 is a cylinder. When the first driving member 31 extends, it pushes the force arm structure 322 to drive the entire force arm 32 to rotate in the horizontal direction. As the force arm 32 rotates, the cam structure 321 gradually presses down on the pressure block 33. At this time, the cam structure 321 applies a vertical downward pressure to the pressure block 33, so that the pressure block 33 is pressed down and tightly adheres to the surface of the machine tool 1 to achieve locking.

[0044] like Figures 1 to 4 As shown, the machine tool 1 has a first slide rail 11 extending along its length. Understandably, the first slide rail 11 can be a groove formed on the surface of the machine tool 1 or a guide rail formed on the surface of the machine tool 1, to provide motion guidance for the slide table unit 21 and ensure smooth movement.

[0045] The slide unit 21 includes a slide 211 and a placement assembly 212. The slide 211 is mounted on the machine tool 1 and slidably connected to the first slide rail 11. The first drive unit 22 is connected to the two slides 211 to drive the two slides 211 to move towards or away from each other. The two placement assemblies 212 are respectively disposed on the corresponding slides 211 for carrying workpieces. In this embodiment, the first drive unit 22 controls the two slides 211 to move towards or away from each other to ensure the synchronization of their movements and improve efficiency and accuracy.

[0046] Understandably, when the cam structure 321 applies a vertically downward pressure to the pressure block 33, the pressure block 33 in this embodiment is pressed down and tightly adheres to the surface of the first slide rail 11 to achieve locking.

[0047] Furthermore, it should be noted that the workpiece in this embodiment has a roller and a shaft. The roller is sleeved on the periphery of the shaft, and both ends of the shaft are exposed outside the roller. At this time, the roller and the shaft are not fixedly installed, that is, the shaft can move arbitrarily along the radial direction of the roller.

[0048] The placement component 212 includes a first V-shaped platform 2121, a second V-shaped platform 2122, a photoelectric switch 2123, and a second drive component 2124. Both the first V-shaped platform 2121 and the second V-shaped platform 2122 have V-shaped grooves, which are used to support the roller and shaft of the workpiece, respectively. The first V-shaped platform 2121 and the second V-shaped platform 2122 are located on the side of the slide table 211 facing the other slide table 211, and the first V-shaped platform 2121 and the second V-shaped platform 2122 are spaced apart in a direction away from the other slide table 211 to provide support for the workpiece and prevent the workpiece from rolling or deviating. The first V-shaped platform 2121 is used to support the roller of the workpiece, and the second V-shaped platform 2122 is used to support the shaft of the workpiece. A photoelectric switch 2123 is provided on the side of the first V-shaped platform 2121 facing the other V-shaped platform to detect whether the workpiece is being loaded. When the workpiece enters the detection area, it blocks the light path, triggers a signal, and notifies the operator that the workpiece has been placed, thereby starting the subsequent actions. The second drive unit 2124 is connected to the machine tool 1 and to the second V-shaped table 2122 to drive the second V-shaped table 2122 to rise and fall.

[0049] Based on the above structure, the workpiece is fed in, its roller is placed on the first V-shaped platform 2121, and the shaft is mounted on the second V-shaped platform 2122. The photoelectric switch 2123 detects that the workpiece has been loaded and sends a signal to the control system. By controlling the lifting and lowering of the second V-shaped platform 2122, the height of the second V-shaped platform 2122 is adjusted to adjust the position of the shaft so that the roller and the shaft are approximately concentric. Then, the pressing head unit 42 presses the bearing seat into the designated position inside the roller to complete the pressing. In this embodiment, the second driving component 2124 is a motor or a cylinder.

[0050] Furthermore, the first drive unit 22 includes a third drive member 221 and a first lead screw structure 222. The third drive member 221 and the first lead screw structure 222 are mounted on the machine tool 1. The two ends of the first lead screw structure 222 are respectively provided with a first thread and a second thread, and the thread directions of the first thread and the second thread are opposite. Two slides 211 are respectively connected to the two ends of the first lead screw structure 222, and the third drive member 221 is connected to one end of the first lead screw structure 222 to drive the two slides 211 to move towards or away from each other.

[0051] Based on the above structure, when the first lead screw structure 222 rotates forward under the drive of the third drive member 221, the two slides 211 move towards each other; when the first lead screw structure 222 rotates in the opposite direction under the drive of the third drive member 221, the two slides 211 move away from each other. In this embodiment, the synchronous symmetrical movement of the two slides 211 can be achieved by driving the first lead screw structure 222 with one third drive member 221, without the need for additional transmission mechanisms or multiple drive sources.

[0052] It should be noted that the first lead screw structure 222 in this embodiment is a conventional lead screw structure, and its structure is not particularly limited here, and the third driving component 221 is a motor.

[0053] like Figures 5 to 7 As shown, the pressing head unit 42 includes a pressing head assembly 421, a nesting assembly 422, and a connecting shaft assembly 423. The pressing head assembly 421 is slidably mounted on the base 41. The second driving unit 43 is connected to the pressing head assembly 421 to drive the pressing head assembly 421 away from or closer to another pressing head assembly 421. In this embodiment, two symmetrically arranged pressing head assemblies 421 are set to perform pressing operations from both sides simultaneously.

[0054] One end of the nesting assembly 422 passes through the press head assembly 421 and is retractably installed inside the press head assembly 421. The other end of the nesting assembly 422 is exposed on the side of the press head assembly 421 facing the other press head assembly 421. One end of the connecting shaft assembly 423 is located inside the press head assembly 421, and the other end is retractably installed at one end of the nesting assembly 422 and can be exposed at the other end of the nesting assembly 422.

[0055] Based on the above structure, when the second drive unit 43 is activated, it drives the pressing head assembly 421 to slide along the base 41, allowing the entire assembly to move closer to or further away from the pressing head assembly 421 on the opposite side. During the pressing process, the sleeve assembly 422 moves axially along the pressing head assembly 421 to extend relative to the pressing head assembly 421, fitting the bearing seat onto the extended portion of the sleeve assembly 422 to complete the loading. Subsequently, the shaft assembly 423 extends out of the sleeve assembly 422 by telescoping within the sleeve assembly 422 to abut against the shaft of the workpiece. At this time, the second drive unit 43 is activated, driving the pressing head assembly 421 to push the bearing seat into the designated position inside the roller.

[0056] Furthermore, the pressing mechanism 4 also includes a second slide rail 44, a limiting block 45, and a stop block 46. The stop block 46 is mounted on the base 41 and is used to limit the movement range of the limiting block 45.

[0057] The press-fit head assembly 421 includes a housing 4211, a first connector 4212, and a slider 4213. The housing 4211 is the main structure of the press-fit head assembly 421 and is used to accommodate internal components, such as the nesting assembly 422 and the connecting shaft assembly 423. The housing 4211 is slidably connected to the second slide rail 44 through the slider 4213. One end of the nesting assembly 422 passes through the housing 4211 and is telescopically installed inside the housing 4211. The other end of the nesting assembly 422 is exposed on the side of the housing 4211 facing the other housing 4211. The other side of the housing 4211 is connected to the second drive unit 43 through the first connector 4212. The limiting block 45 is installed on the periphery of the housing 4211 and is correspondingly set with the stop block 46.

[0058] Based on the above structure, the second drive unit 43 is activated, pushing the outer shell 4211 through the first connector 4212, causing the outer shell 4211 to slide smoothly along the second slide rail 44. The nesting assembly 422 moves with the outer shell 4211 and presses the bearing seat into the roller, completing the pressing action. In addition, when the pressing head assembly 421 moves to a specific position, the limit block 45 will encounter the stop block 46, thereby limiting the stroke or position of the pressing head, preventing overpressure or mechanical collision, and playing a role in safety protection and positioning accuracy control.

[0059] Furthermore, the outer casing 4211 has a first sliding groove 42111. In this embodiment, the first sliding groove 42111 is located at the top of the outer casing 4211. The nesting assembly 422 includes a nesting head 4221, a second connector 4222, a first drive block 4223, and a fourth drive member 4224. The fourth drive member 4224 is installed on the periphery of the outer casing 4211. The second connector 4222 is located inside the outer casing 4211 and is connected to the nesting head 4221. The nesting head 4221 serves as the part for placing the bearing seat and performing the pressing action. One end of the nesting head 4221 away from the second connector 4222 is exposed outside the outer casing 4211. The first drive block 4223 is connected to the outside of the second connector 4222. The first drive block 4223 passes through the first sliding groove 42111 and is connected to the fourth drive member 4224 to drive the nesting head 4221 to perform telescopic movement relative to the outer casing 4211.

[0060] In this embodiment, when the nesting assembly 422 is in its initial state, the nesting head 4221 is partially exposed outside the housing 4211. When the bearing seat needs to be placed, the fourth driving member 4224 pushes the first driving block 4223 to slide along the first sliding groove 42111, thereby driving the second connecting member 4222 to move back and forth, which in turn drives the nesting head 4221 to extend and retract synchronously, allowing the operator to place the bearing seat on the exposed part and complete the loading of the bearing seat. In this embodiment, the fourth driving member 4224 is a cylinder.

[0061] Furthermore, the outer casing 4211 is also provided with a second sliding groove 42112. In this embodiment, the second sliding groove 42112 is located on the side of the outer casing 4211. The connecting shaft assembly 423 includes a connecting shaft 4231, a third connecting member 4232, a second driving block 4233, and a fifth driving member 4234. The fifth driving member 4234 is installed on the periphery of the outer casing 4211. The third connecting member 4232 is located inside the outer casing 4211. One end of the third connecting member 4232 is connected to the connecting shaft 4231 and is located inside the second connecting member 4222. The second driving block 4233 is connected to the outside of the third connecting member 4232. The second driving block 4233 passes through the second sliding groove 42112 and is connected to the fifth driving member 4234 to drive the connecting shaft 4231 to perform telescopic movement relative to the sleeve assembly 422.

[0062] In this embodiment, the fifth driving component 4234 is activated, pushing the second driving block 4233 to slide along the second slide groove 42112, thereby driving the third connecting component 4232 to move back and forth, which in turn drives the connecting shaft 4231 to extend and retract synchronously, so as to abut against the shaft of the workpiece and prevent shaft offset. In this embodiment, the fifth driving component 4234 is a cylinder.

[0063] In practical applications, the bearing housing press-fitting device can also be equipped with displacement sensors and pressure sensors to monitor the displacement and torque of the mating shaft 4231 and the sleeve head 4221. When the press-fitting process reaches the pre-set designated position, the press-fitting action will stop immediately to ensure the accuracy of the entire press-fitting process.

[0064] Furthermore, the second drive unit 43 includes a sixth drive member 431 and a second lead screw structure 432. The sixth drive member 431 is mounted on the base 41 and is connected to the press head unit 42 through the second lead screw structure 432.

[0065] Based on the above structure, the sixth drive unit 431 outputs rotational motion and transmits it to the second lead screw structure 432. The second lead screw structure 432 converts the rotation into linear motion and drives the pressing head unit 42 to move back and forth to press the bearing seat into the roller to complete the pressing operation.

[0066] It should be noted that the second lead screw structure 432 in this embodiment is a conventional lead screw structure, and its structure is not particularly limited here, and the sixth driving component 431 is a motor.

[0067] In summary, this utility model embodiment provides a bearing seat pressing device. Throughout the pressing process, the locking mechanism 3 remains locked, ensuring a tight fit between the slide unit 21 and the machine tool 1, preventing free movement. This effectively prevents the slide unit 21 from tilting due to a sudden surge in pressure during pressing, thus ensuring a smooth and reliable pressing process and avoiding significant deviations in the concentricity of the bearing seats at both ends of the workpiece, which would affect the assembly quality and overall performance of the idler roller. Furthermore, when the workpiece specifications change, the locking mechanism 3 can be unlocked, allowing the slide unit 21 to move freely on the machine tool 1. This allows the equipment to be flexibly adjusted according to the new workpiece specifications, adapting to diverse production needs.

[0068] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
