Description

Technical Field

[0001] This utility model relates to the field of bearing press-fitting auxiliary technology, and in particular to an assembly device for press-fitting bearings. Background Technology

[0002] In the manufacturing of products with rotating parts (such as small fans), bearing installation is the core process to ensure low friction operation of the shaft. Its assembly accuracy directly affects the equipment life and smooth operation. In the existing technology, bearing press fitting generally adopts a step-by-step operation. First, the bearing is pre-placed in the mounting hole of the workpiece (such as the fan housing), and then it is positioned by a special fixture and transferred to an independent station for press-fitting.

[0003] This type of sequential assembly mode has significant drawbacks. Due to the structural characteristics of the fixture, the fixture cannot be directly pressed into place at the initial station after the bearing is pre-placed. It needs to be transferred to a secondary process for pressing, which significantly increases the equipment footprint and the complexity of the production line layout. Furthermore, during the transfer process, since the bearing is placed on the mounting hole of the workpiece, it is easy to slip off due to vibration, resulting in pressing failure. Utility Model Content

[0004] The purpose of this invention is to provide an assembly device for press-fitting bearings, which uses a gripping mechanism to adsorb the bearing and position it to the workpiece mounting hole, and then press-fits it simultaneously.

[0005] The technical solution adopted by the assembly equipment for press-fitting bearings disclosed in this utility model is as follows:

[0006] The device includes a machine base, a feeding mechanism, and a gripping mechanism. The machine base has a worktable with a pressing area, a loading mechanism, and a lifting mechanism. A carrier plate is slidably connected to the feeding mechanism, and a storage slot is provided on the carrier plate. The discharge end of the loading mechanism extends above the carrier plate. The gripping mechanism is slidably connected to the lifting mechanism and has a pressing rod located above the pressing area. A positioning rod is provided on the pressing rod. A magnetic component is provided inside the gripping mechanism, and both the pressing rod and the positioning rod are in contact with the magnetic component. The feeding mechanism drives the storage slot of the carrier plate to reciprocate to move below the discharge end of the loading mechanism or into the pressing area.

[0007] As a preferred embodiment, the gripping mechanism includes a connecting seat, the pressing rod is fixedly connected to the connecting seat, the magnetic component is placed inside the connecting seat, the positioning rod passes through the pressing rod and contacts the magnetic component, and the diameter of the positioning rod is smaller than the diameter of the pressing rod.

[0008] As a preferred embodiment, the lifting mechanism includes a lead screw assembly, which is fixedly connected to the machine base. A slide block is slidably connected to the lead screw assembly, and the connecting seat is fixedly connected to the slide block.

[0009] As a preferred embodiment, the feeding mechanism includes a base, a feeding cylinder is fixedly connected to the base, the carrier plate is slidably connected to the base, and the output shaft of the feeding cylinder is fixedly connected to the carrier plate.

[0010] As a preferred embodiment, the feeding mechanism includes a vibratory feeder, the discharge end of which is connected to a feeding pipe, and the discharge end of the feeding pipe extends above the carrier plate.

[0011] As a preferred embodiment, there are two carrier plates, two feeding cylinders, and two discharge ends of the vibratory feeder, with the two carrier plates arranged alternately on the base.

[0012] As a preferred embodiment, a lifting cylinder is fixedly connected to the machine base, the output shaft of the lifting cylinder is fixedly connected to the worktable, and a slot is provided in the pressing area.

[0013] As a preferred embodiment, two limiting arms are fixedly connected to the machine base, with the two limiting arms respectively close to both sides of the pressing area.

[0014] The beneficial effects of the assembly equipment for press-fitting bearings disclosed in this utility model are:

[0015] The feeding mechanism pulls the carrier plate away from the pressing area, so that the placement slot on the carrier plate moves to below the discharge end of the feeding mechanism, allowing the feeding mechanism to put a single bearing into the placement slot. The feeding mechanism pushes the carrier plate closer to the pressing area, so that the bearing is located below the positioning rod.

[0016] The lifting mechanism drives the gripping mechanism to slide down, so that the positioning rod enters the inner ring of the bearing. The positioning rod and the bearing are in clearance fit, and the positioning rod can be used to center the bearing. At the same time, the magnetic component attracts the bearing to the positioning rod through the pressing rod and the positioning rod. The lifting mechanism drives the gripping mechanism to slide up, and after the bearing is taken out from the storage slot, the feeding mechanism pulls the carrier plate to slide away from the pressing area, and the loading mechanism places the next wheel bearing.

[0017] The external transfer device places the workpiece into the pressing area. The lifting mechanism drives the gripping mechanism to slide down, and the pressing rod pushes the bearing into the mounting hole of the workpiece. The bearing and the mounting hole are interference-fitted. The lifting mechanism drives the gripping mechanism to slide up, pulls the positioning rod out of the bearing, and the external transfer device takes the workpiece with the bearing pressed out from the pressing area, thus realizing the simultaneous completion of the bearing gripping and pressing work in one process.

[0023] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0024] Please refer to Figure 1 and Figure 2 .

[0025] The present invention discloses an assembly equipment for press-fitting bearings, comprising a machine base 1, a gripping mechanism 3, and a feeding mechanism 5;

[0026] The machine 1 is equipped with a worktable 12, and a lifting cylinder 11 is fixedly connected to the machine 1. The output shaft of the lifting cylinder 11 is fixedly connected to the worktable 12. The worktable 12 is equipped with a pressing area, and a slot 121 is opened on the worktable 12. The slot 121 is located in the pressing area.

[0027] Furthermore, two limiting arms 13 are fixedly connected to the machine base 1, and the two limiting arms 13 are respectively close to the two sides of the pressing area;

[0028] When the pressing area is unloaded, the lifting cylinder 11 pushes the worktable 12 down, allowing the external transfer device more room to place the workpiece into the pressing area. After the workpiece is placed, the lifting cylinder 11 pulls the worktable 12 up, so that the workpiece is between the two limit arms 13, preventing the workpiece from shifting when the pressing rod 32 presses into the bearing 6. After the workpiece has completed the pressing of the bearing 6, the lifting cylinder 11 pushes the worktable 12 down, making it easier for the external transfer device to remove the pressed workpiece. The worktable 12 then waits for the next workpiece to be placed.

[0029] Please refer to Figures 1-4 .

[0030] The machine base 1 is equipped with a lifting mechanism 2, and the gripping mechanism 3 is slidably connected to the lifting mechanism 2. The lifting mechanism 2 includes a lead screw device 21; the lead screw device 21 is fixedly connected to the machine base 1, and a slide block 211 is slidably connected to the lead screw device 21.

[0031] The feeding mechanism 5 is fixedly connected to the slide 211. The gripping mechanism 3 includes a connecting seat 31. The connecting seat 31 is fixedly connected to the slide 211. The gripping mechanism 3 is provided with a pressing rod 32, which is fixedly connected to the connecting seat 31. The pressing rod 32 is located above the pressing area. The gripping mechanism 3 is provided with a magnetic element 311, which is placed inside the connecting seat 31. The pressing rod 32 and the positioning rod 321 are both in contact with the magnetic element 311. The pressing rod 32 is provided with a positioning rod 321, which passes through the pressing rod 32 and contacts the magnetic element 311. The diameter of the positioning rod 321 is smaller than the diameter of the pressing rod 32. The end of the positioning rod 321 extends into a conical part, which is away from the pressing rod 32.

[0032] The lead screw device 21 pushes the slide block 211 to slide down, so that the pressing rod 32 and the positioning rod 321 are close to the pressing area; the lead screw device 21 pulls the slide block 211 to slide up, so that the pressing rod 32 and the positioning rod 321 are away from the pressing area.

[0033] Please refer to Figure 1 and Figure 5 .

[0034] The machine base 1 is equipped with a feeding mechanism 4, which includes a vibrating plate. The vibrating plate is fixedly connected to the top of the machine base 1. In this embodiment, it is preferred that there are two discharge ends on the vibrating plate. The two discharge ends on the vibrating plate respectively push out a bearing 6 with a larger diameter and a bearing 6 with a smaller diameter. The discharge ends of the vibrating plate are connected to a feeding pipe 41.

[0035] The feeding mechanism 5 includes a base 51, on which a feeding cylinder 511 is fixedly connected. In this embodiment, two feeding cylinders 511 are preferably used. A carrier plate 52 is slidably connected to the feeding mechanism 5. In this embodiment, two carrier plates 52 are preferably used. The carrier plate 52 is slidably connected to the base 51. The output shaft of the feeding cylinder 511 is fixedly connected to the carrier plate 52. The sliding path of the carrier plate 52 is parallel to the output shaft of the feeding cylinder 511. A storage groove is provided on the carrier plate 52. The storage groove is away from the feeding cylinder 511. The discharge ends of the two feeding pipes 41 extend to the top of the two carrier plates 52 respectively.

[0036] Furthermore, the two carrier plates 52 are tilted at a certain angle to the sides with respect to the center of the pressing area, so that the two carrier plates 52 are staggered on the base 51, so that when the feeding cylinder 511 pushes the carrier plate 52 into the pressing area, the placement groove on the carrier plate 52 can be located in the pressing area, and only one feeding cylinder 511 needs to operate.

[0037] The feeding mechanism 5 pulls the carrier plate 52 to slide away from the pressing area, so that the placement slot 121 is below the discharge end of the feeding pipe 41, allowing the bearing 6 to be placed in the placement slot. Moreover, only one bearing 6 is placed in a single feeding. The other bearings 6 in the feeding pipe 41 will be constrained by the carrier plate 52 in the feeding pipe 41 and will not fall out of the feeding pipe 41. The feeding mechanism 5 pushes the carrier plate 52 to slide closer to the pressing area, so that the placement slot 121 is in the pressing area. The slot 121 can provide space for the carrier plate 52 to enter the pressing area, avoiding the carrier plate 52 from directly hitting the worktable 12.

[0038] Please refer to Figures 1-5 .

[0039] During work:

[0040] One of the feeding pipes 41 places the bearing 6 into the storage slot on one of the carrier plates 52. The feeding mechanism 5 pushes the carrier plate 52 to slide closer to the pressing area, so that the storage slot 121 is in the pressing area. The lifting mechanism 2 drives the gripping mechanism 3 to slide down, so that the positioning rod 321 passes through the inner ring of the bearing 6. The positioning rod 321 is clearance-fitted with the bearing 6 and plays the role of positioning the center of the bearing 6. The magnetic component 311 attracts the bearing 6 to the positioning rod 321 through the pressing rod 32 and the positioning rod 321. The lifting mechanism 2 drives the gripping mechanism 3 to slide up, and removes the bearing 6 from the storage slot. At the same time, the lifting cylinder 11 pushes the worktable 12 down, so that the external transfer device puts the workpiece into the pressing area.

[0041] After the feeding mechanism 5 pulls the carrier plate 52 away from the pressing area, the lifting cylinder 11 pulls the worktable 12 up, so that the workpiece is located between the two limit arms 13; the lifting mechanism 2 drives the gripping mechanism 3 to slide down, and the pressing rod 32 pushes the bearing 6 into the mounting hole of the workpiece, and the bearing 6 is interference-fitted with the mounting hole; the lifting mechanism 2 drives the gripping mechanism 3 to slide up, pulls the positioning rod 321 out of the bearing 6, and the lifting cylinder 11 pushes the worktable 12 down, so that the external transfer device can take away the workpiece that has been pressed, thereby realizing the simultaneous completion of the gripping and pressing of the bearing 6 in one process.

[0042] When the mounting hole of the workpiece needs to install a bearing 6 of a different size, the positioning rod 321 is removed from the pressing rod 32, and the positioning rod 321 with the corresponding inner ring size of the bearing 6 is replaced and installed back into the pressing rod 32. The operation of one of the feeding cylinders 511 is paused, and the operation of the other feeding cylinder 511 is started, so that the other carrier plate 52 provides the gripping mechanism 3 with a bearing 6 of the corresponding size, thereby realizing the rapid switching of bearings 6 of other sizes for assembly.

[0043] This utility model provides an assembly device for press-fit bearings. The feeding mechanism pulls the carrier plate to slide away from the press-fit area, so that the placement groove on the carrier plate moves to below the discharge end of the feeding mechanism, allowing the feeding mechanism to put a single bearing into the placement groove. The feeding mechanism pushes the carrier plate to slide closer to the press-fit area, so that the bearing is located below the positioning rod.

[0044] The lifting mechanism drives the gripping mechanism to slide down, so that the positioning rod enters the inner ring of the bearing. The positioning rod and the bearing are in clearance fit, and the positioning rod can be used to center the bearing. At the same time, the magnetic component attracts the bearing to the positioning rod through the pressing rod and the positioning rod. The lifting mechanism drives the gripping mechanism to slide up, and after the bearing is taken out of the storage slot, the feeding mechanism pulls the carrier plate to slide away from the pressing area, and the loading mechanism places the next wheel bearing.

[0045] The external transfer device places the workpiece into the pressing area. The lifting mechanism drives the gripping mechanism to slide down, and the pressing rod pushes the bearing into the mounting hole of the workpiece. The bearing and the mounting hole are interference-fitted. The lifting mechanism drives the gripping mechanism to slide up, pulls the positioning rod out of the bearing, and the external transfer device takes the workpiece with the bearing pressed out from the pressing area, thus realizing the simultaneous completion of the bearing gripping and pressing work in one process.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
