Description

Technical Field

[0001] This utility model relates to the field of bearing housing processing technology, specifically to an assembly machine for bearing housing processing. Background Technology

[0002] The bearing housing rotating assembly includes a rotating shaft and bearings. The outer diameters at both ends of the rotating shaft are smaller than the outer diameter at the middle. Two bearings can be installed into the two ends of the rotating shaft respectively. The traditional installation process of the bearing housing rotating assembly mainly involves first installing the two bearings into the two ends of the rotating shaft respectively, and then manually hammering them in. This is time-consuming and laborious, and poses certain safety hazards. Continuous hammering of the assembly can also easily damage the assembly.

[0003] According to a public notice (Announcement No.: CN215035126U) of a bearing housing assembly machine, the bearing housing to be assembled is placed on the lower fixture, then a rotating shaft is placed on it, one end of the rotating shaft is inserted into the bearing housing, and another bearing housing is installed on the other end of the rotating shaft. Finally, the lifting device drives the push head to move downward, and the upper fixture on the push head moves closer to the lower fixture, reducing the assembly space. The bearing housings at both ends of the rotating shaft are pressed into the rotating shaft by force, thus completing the assembly of the bearing housing. The whole process is efficient and convenient, eliminating the need for manual repeated hammering of the bearing housing into the rotating shaft, reducing damage to the product, and improving production efficiency.

[0004] However, the lack of guidance during pressing makes it impossible to ensure that the shaft is completely aligned with the axis of the bearing housing, which can easily lead to tilting or offset, resulting in installation deviations. This causes the drive shaft to be subjected to uneven forces during operation, which exacerbates bearing wear. Utility Model Content

[0005] The purpose of this invention is to provide an assembly machine for processing bearing housings, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an assembly machine for processing bearing seats, comprising a worktable, support legs, a lower tooling, a guide column, a push plate, a mounting plate, a cylinder, a push head, and an upper tooling. A guide assembly is provided on the surface of the worktable, the guide assembly including a column, the column being fixedly connected to the surface of the worktable, multiple sets of neatly arranged slots being provided on the side wall of the column, a bearing plate being slidably connected to the outer wall of the column, two sets of symmetrically arranged sliding grooves being provided on the surface of the bearing plate, a sliding plate being slidably connected inside the sliding groove, an extension rod being fixedly connected to the side wall of the sliding plate, a V-shaped plate being fixedly connected to the end of the extension rod, a side rod being fixedly connected to the side wall of the sliding plate, and the two sets of side rods being threadedly connected by a bidirectional threaded rod, the end of the bidirectional threaded rod being fixedly fitted with a rotating wheel.

[0007] Preferably, the surface of the support plate is provided with a limiting component, the limiting component includes a groove, the groove is formed on the surface of the support plate, and two sets of symmetrically arranged movable plates are slidably connected inside the groove. The side wall of the movable plate is fixedly connected with a plug rod, and the plug rod is inserted into the inside of the slot.

[0008] Preferably, the side wall of the slide plate has a through hole, and a positioning rod is slidably connected in the through hole, with the end of the positioning rod fixedly connected to the inside of the slide groove.

[0009] Preferably, the side wall of the V-shaped plate is provided with an installation groove, and a roller is rotatably connected inside the installation groove.

[0010] Preferably, a through groove is formed at the center of the surface of the support plate.

[0011] Preferably, the side wall of the movable plate has a through hole, and a crossbar is slidably connected in the through hole, with the end of the crossbar fixedly connected inside the groove.

[0012] Preferably, the two sets of movable plates are elastically connected by a return spring.

[0013] Compared with the prior art, this utility model provides an assembly machine for processing bearing housings, which has the following advantages:

[0014] 1. This assembly machine for bearing housing processing uses a rotary wheel to drive a bidirectional threaded rod to rotate, causing two sets of side rods to move towards each other. This moves the slide plate and V-shaped plate closer to the outer wall of the drive shaft, and the roller contacts the outer wall of the drive shaft, allowing the drive shaft to move vertically. This ensures the convenience and accuracy of installation between the drive shaft and the bearing housing, effectively avoiding assembly defects caused by positional misalignment during the pressing process, and improving the assembly quality of the product.

[0015] 2. This assembly machine for bearing housing processing uses a movable plate to disengage the insert rod from the current slot. At this time, the support plate can slide on the column. After reaching the appropriate position, the movable plate is released, and under the action of the return spring, the insert rod is inserted into the corresponding slot, thereby realizing the adjustment and fixation of the support plate height to adapt to the requirements of different length drive shafts or different assembly processes.

Detailed Implementation

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: an assembly machine for processing bearing seats, including a worktable 1, a support leg 11 fixedly connected to the bottom surface of the worktable 1, a lower tooling 2 and two sets of symmetrically arranged guide columns 3 fixedly installed on the surface of the worktable 1, a push plate 31 slidably connected to the outer wall of the guide column 3, an mounting plate 32 fixedly connected to the top of the guide column 3, a cylinder 33 fixedly connected to the surface of the mounting plate 32, the output shaft of the cylinder 33 passing through and slidably connected to the bottom surface of the mounting plate 32, the output shaft of the cylinder 33 being fixedly connected to the surface of the push plate 31, a push head 34 fixedly connected to the bottom surface of the mounting plate 32, an upper tooling 35 fixedly connected to the bottom surface of the push head 34, the upper tooling 35 and the lower tooling 2 being used to fix the bearing seats, a drive shaft located between the bearing seats, and the push plate 31 being moved downward by the cylinder 33 to press the bearing seats into both ends of the drive shaft respectively.

[0022] like Figures 1-4As shown, a guide assembly 4 is provided on the surface of the workbench 1. The guide assembly 4 includes a column 41, which is fixedly connected to the surface of the workbench 1. Multiple sets of neatly arranged slots 42 are provided on the side wall of the column 41. A support plate 43 is slidably connected to the outer wall of the column 41. The column 41 has four sets of slots for positioning the support plate 43. The slots 42 are used in conjunction with the limiting assembly 5 to adjust and fix the height of the support plate 43. A through groove 431 is provided at the center of the surface of the support plate 43 for the drive shaft to pass through. Two sets of symmetrically arranged sliding grooves 44 are provided on the surface of the support plate 43. A sliding plate 45 is slidably connected inside the sliding groove 44. A through hole is provided on the side wall of the sliding plate 45, and a positioning rod 46 is slidably connected in the through hole. The end of the positioning rod 46 is fixedly connected inside the sliding groove 44. The positioning rod 46 provides guidance and positioning for the sliding plate 45 inside the sliding groove 44, allowing the sliding plate 45 to move stably within the sliding groove 44. An extension rod 47 is fixedly connected to the side wall of the slide plate 45. A V-shaped plate 48 is fixedly connected to the end of the extension rod 47. The extension rod 47 connects the V-shaped plate 48 and the slide plate 45, so that the slide plate 45 can drive the V-shaped plate 48 to move synchronously. The side wall of the V-shaped plate 48 can better fit with the outer wall of the drive shaft. A side rod 49 is fixedly connected to the side wall of the slide plate 45. The two sets of side rods 49 are threaded together by a double-threaded rod 410. A rotating wheel 411 is fixed to the end of the double-threaded rod 410. The rotating wheel 411 is used to drive the double-threaded rod 410 to rotate, so that the two sets of side rods 49 move towards each other, thereby driving the slide plate 45 and the V-shaped plate 48 to approach the outer wall of the drive shaft. The two sets of V-shaped plates 48 are used to position the drive shaft to prevent the drive shaft from shifting during the pressing process. A mounting groove 412 is provided on the side wall of the V-shaped plate 48. A roller 413 is rotatably connected inside the mounting groove 412. The roller 413 contacts the outer wall of the drive shaft on the outer wall of the V-shaped plate 48 near the drive shaft, so that the drive shaft can move vertically, thereby facilitating the installation between the drive shaft and the bearing seat.

[0023] like Figures 1-4As shown, a limiting component 5 is provided on the surface of the support plate 43. The limiting component 5 includes a groove 51, which is formed on the surface of the support plate 43. Two sets of symmetrically arranged movable plates 52 are slidably connected inside the groove 51. The sidewall of the movable plate 52 has a through hole, and a crossbar 53 is slidably connected in the through hole. The end of the crossbar 53 is fixedly connected inside the groove 51. The crossbar 53 is used to position and guide the movable plate 52 in the groove 51 to ensure the stability of the movable plate 52 during movement. The two sets of movable plates 52 are elastically connected by a return spring 54. A plug rod 55 is fixedly connected to the sidewall of the movable plate 52 and is inserted into the slot 42. When the height of the support plate 43 needs to be adjusted, the insert rod 55 is disengaged from the current slot 42 by moving the movable plate 52. At this time, the support plate 43 can slide on the column 41. After reaching the appropriate position, the movable plate 52 is released, and under the action of the return spring 54, the insert rod 55 is inserted into the corresponding slot 42, thereby realizing the adjustment and fixation of the height of the support plate 43 to adapt to the requirements of different length drive shafts or different assembly processes.

[0024] In this invention, during use, the height of the support plate 43 is first adjusted by operating the limiting component 5 according to the length of the drive shaft to be assembled. Specifically, the movable plate 52 is moved to disengage the insertion rod 55 from the current slot 42, then the support plate 43 is slid on the column 41 to a suitable height, the movable plate 52 is released, and under the action of the return spring 54, the insertion rod 55 is inserted into the corresponding slot 42, thus fixing the height of the support plate 43.

[0025] Next, place a bearing seat on the lower fixture 2, pass the drive shaft through the through groove 431 of the bearing plate 43 and insert one end into the bearing seat, then rotate the rotating wheel 411 to drive the bidirectional threaded rod 410 to rotate, so that the two sets of side rods 49 move towards each other, driving the slide plate 45 and V-shaped plate 48 to approach the outer wall of the drive shaft. The two sets of V-shaped plates 48 are used to position the drive shaft to ensure its accurate position and avoid displacement during the subsequent pressing process.

[0026] Next, another bearing housing is placed at the other end of the drive shaft. The cylinder 33 is then activated. The output shaft of the cylinder 33 drives the push plate 31 to move downwards along the guide post 3. The push plate 31 drives the push head 34 and the upper tooling 35 to move downwards simultaneously. The upper tooling 35 cooperates with the lower tooling 2 to press the two bearing housings into both ends of the drive shaft. During the pressing process, the roller 413 on the side wall of the V-shaped plate 48 contacts the outer wall of the drive shaft, allowing the drive shaft to move vertically, facilitating the smooth installation of the bearing housings and the drive shaft.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
