Description

Technical Field

[0001] The utility model belongs to the technical field related to bearing press-fitting, and particularly relates to a precise bearing fixture for automatically press-fitting bearings. Background Art

[0002] Bearing press-fitting is an essential step in the bearing installation process. It involves precisely installing the bearing onto the shaft or bearing seat to ensure that the bearing can work normally and stably. By applying appropriate pressure, the inner or outer ring of the bearing is tightly fitted with the shaft or bearing seat to achieve an interference fit, transition fit or clearance fit between the two, depending on the type, size and application scenario of the bearing.

[0003] During the typical bearing press-fitting process, a fixture is used to position the bearing and bearing seat to prevent misalignment and other issues. However, in practice, the bearing and bearing seat have different diameters, making them difficult to clamp synchronously. Using a separate clamping device, the two components cannot be rotated and maintained coaxially, which can easily lead to misalignment. To address this issue, we have developed a precision bearing fixture for automatic bearing press-fitting to address these technical issues. Utility Model Content

[0004] The purpose of the present invention is to provide a precise bearing fixture for automatically pressing bearings, which solves the problems in the above-mentioned background technology by adjusting the specific structural design of the support component, the clamping mechanism and the pusher component.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model provides a bearing precision fixture for automatically pressing bearings, including an adjusting support assembly, a clamping mechanism slidingly arranged on the upper surface of the adjusting support assembly, the clamping mechanism including two symmetrically slidably arranged clamping assemblies, the clamping assembly including a first clamping plate, a second clamping plate and a transmission support frame, the peripheral side surfaces of the first clamping plate are rotatably connected to the first transmission link and the second transmission link, one end of the first transmission link is rotatably connected to one end of the second transmission link; the side surfaces of the second clamping plate are rotatably connected to the first balancing link and the second balancing link, one end of the first balancing link is rotatably connected to one end of the second balancing link, and the other end of the second transmission link is rotatably connected to the other end of the first balancing link, and the second transmission link and the first balancing link are both rotatably connected to the transmission support frame; a pushing assembly is fixedly connected to the upper surface of the adjusting support assembly, and the pushing assembly includes a horizontally movable pushing plate.

[0007] The utility model is further configured such that the adjustment support assembly includes an adjustment support platform, two guide grooves are symmetrically provided on the surface of the adjustment support platform, and a hollow support seat is fixedly connected to the upper surface of the adjustment support platform; a driving connecting rod is rotatably connected to the lower surface of the adjustment support platform, and both ends of the driving connecting rod are rotatably connected to adjustment connecting rods.

[0008] The present invention is further configured such that the clamping assembly also includes a supporting vertical plate, the lower surface of the supporting vertical plate is fixedly connected to an extension block that slides with the corresponding guide groove, and one end of the adjusting link is rotatably connected to the lower surface of the corresponding extension block; one side of the supporting vertical plate is fixedly connected to a transmission guide rail, the transmission support frame is slidably arranged inside the transmission guide rail, and a reset spring is fixedly connected between the two opposite side surfaces of the transmission support frame and the two opposite inner walls of the transmission guide rail.

[0009] The utility model is further configured such that two ear plates are symmetrically fixedly connected to one side of the support vertical plate close to the transmission guide rail, the other ends of the first transmission link and the second balance link are rotatably connected to the corresponding ear plates, and the other side of one of the support vertical plates is fixedly connected to a transmission rack through an L-shaped support plate.

[0010] The utility model is further configured such that a transmission gear is rotatably connected to one side of the hollow support seat, the transmission gear is meshed with a transmission rack, and the upper surface of the adjustment support platform is fixedly connected to a pushing guide rail through a vertical support plate; a transmission screw is rotatably connected between the two inner side walls of the pushing guide rail, the transmission screw is fixedly connected to the transmission gear, and a pushing transmission block is slidingly provided inside the pushing guide rail with which the transmission screw thread cooperates, and the pushing plate is fixedly connected to the pushing transmission block through a linkage rod.

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model drives the connecting rod to rotate by setting an adjustable support assembly and a clamping assembly. Under the connection of the adjustable connecting rod, the two supporting vertical plates approach each other. When the second clamping plate is in close contact with the bearing seat, as the supporting vertical plate moves, the angle between the first balancing link and the second balancing link increases, the transmission support frame moves upward, so that the angle between the second transmission link and the first transmission link decreases, and the first clamping plate moves further until it is in close contact with the peripheral side of the bearing, thereby realizing synchronous clamping and positioning of the bearing and the bearing seat, keeping the two coaxial, and facilitating the accurate docking of the two during the press-fitting operation.

[0013] 2. The utility model sets a clamping mechanism and a pushing assembly. During the movement of the supporting vertical plate, the transmission rack moves synchronously. Under the meshing action of the transmission rack and the transmission gear, the transmission gear rotates and drives the transmission screw to rotate synchronously. The pushing transmission block slides along the inside of the pushing guide rail, driving the pushing plate to move synchronously, thereby realizing the push-out of the bearing and the bearing seat after press-fitting, and facilitating subsequent press-fitting operations.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] For specific embodiment 1, please refer to Figure 1-6 The utility model is a bearing precision fixture for automatically pressing bearings, including an adjusting support assembly 1. Specifically, a clamping mechanism 2 is slidingly arranged on the upper surface of the adjusting support assembly 1. The clamping mechanism 2 includes two symmetrically slidably arranged clamping assemblies 21. The clamping assembly 21 includes a first clamping plate 211, a second clamping plate 212 and a transmission support frame 213. In the initial state, the first clamping plate 211 is located directly above the second clamping plate 212. The side surfaces of the first clamping plate 211 are rotatably connected to the first transmission link 214 and the second transmission link 215, and one end of the first transmission link 214 is rotatably connected to one end of the second transmission link 215.

[0026] Furthermore, the side surfaces of the second clamping plate 212 are rotatably connected to the first balancing link 216 and the second balancing link 217, one end of the first balancing link 216 is rotatably connected to one end of the second balancing link 217, and the other end of the second transmission link 215 is rotatably connected to the other end of the first balancing link 216. Arc springs are fixedly connected between the first transmission link 214 and the second transmission link 215, between the first balancing link 216 and the second balancing link 217, and between the second transmission link 215 and the first balancing link 216 to maintain stability between the two adjacent links. The second transmission link 215 and the first balancing link 216 are both rotatably connected to the transmission support frame 213. The other side surfaces of the first clamping plate 211 and the second clamping plate 212 are made of elastic material, which is convenient for keeping close contact during clamping.

[0027] Furthermore, a pusher assembly 3 is fixedly connected to the upper surface of the adjustment support assembly 1. The pusher assembly 3 includes a horizontally movable pusher plate 301. The pusher plate 301 moves horizontally back and forth synchronously with the movement of the first clamping plate 211 to push out the press-fitted bearing.

[0028] The operation process of this embodiment is as follows: the bearing seat to be press-fitted is placed on the adjustment support assembly 1, the bearing is located above the bearing seat, and the first clamping plate 211 and the second clamping plate 212 are controlled to move synchronously and approach each other. During this process, the push plate 301 moves in the direction away from the bearing seat. When the two second clamping plates 212 are in close contact with the side surfaces of the bearing seat, the position of the bearing seat is fixed. As the clamping assembly 21 continues to move, the second clamping plate 212 stops moving due to the restriction of the bearing seat, thereby causing the first balancing link 216 and the second balancing link 217 to rotate under external force, thereby increasing the angle between the two. 6, the rotation drives the transmission support frame 213 to move upward, causing the second transmission link 215 to rotate, and the angle between the second transmission link 215 and the first transmission link 214 is reduced, thereby causing the first clamping plate 211 to move further until the two first clamping plates 211 are in contact with the side surfaces of the bearing. At this time, the bearing and the bearing seat are coaxial, and the bearing is located directly above the bearing seat hole. Then, through external pressing equipment, the bearing is pressed down to complete the press-fitting between the bearing and the bearing seat; after the press-fitting is completed, as the two clamping assemblies 21 move away from each other synchronously, the push plate 301 moves toward the bearing seat until the pressed-fitted bearing and the bearing seat are pushed out.

[0029] For specific embodiment 2, please refer to Figure 2-5 On the basis of the specific embodiment 1, specifically, the adjustment support assembly 1 includes an adjustment support platform 101, two guide grooves 102 are symmetrically opened on the surface of the adjustment support platform 101, and a hollow support seat 103 is fixedly connected to the upper surface of the adjustment support platform 101; a driving connecting rod 104 is rotatably connected to the lower surface of the adjustment support platform 101, and a driving motor is installed inside the hollow support seat 103, and the output shaft of the driving motor is fixedly connected to the driving connecting rod 104, and both ends are rotatably connected to the adjustment connecting rod 105.

[0030] Furthermore, the clamping assembly 21 also includes a supporting vertical plate 218, and the lower surface of the supporting vertical plate 218 is fixedly connected to an extension block that slides with the corresponding guide slide groove 102, and one end of the adjusting link 105 is rotatably connected to the lower surface of the corresponding extension block. When the driving link 104 rotates, under the connection action of the two adjusting links 105, the extension block is driven to slide along the inside of the corresponding guide slide groove 102, thereby driving the supporting vertical plates 218 to move away from or approach each other; one side of the supporting vertical plate 218 is fixedly connected to a transmission guide rail 219, and the transmission support frame 213 is slidably arranged inside the transmission guide rail 219, and a return spring is fixedly connected between the two opposite side surfaces of the transmission support frame 213 and the two opposite inner walls of the transmission guide rail 219.

[0031] Furthermore, two ear plates are symmetrically fixedly connected to one side of the support vertical plate 218 close to the transmission guide rail 219, and the other ends of the first transmission link 214 and the second balance link 217 are rotatably connected to the corresponding ear plates, and the other side of one of the support vertical plates 218 is fixedly connected to the transmission rack 22 through an L-shaped support plate.

[0032] The operation process of this embodiment is as follows: the bearing seat to be press-fitted is placed on the upper surface of the hollow support seat 103, the driving motor is started, and the driving connecting rod 104 is driven to rotate clockwise (as shown in FIG. Figure 3 As shown), under the connection of the two adjusting links 105, 104 rotates clockwise (as shown Figure 3 As shown), the extension blocks are driven to slide along the corresponding guide slots 102 and approach each other, thereby driving the two support vertical plates 218 to move synchronously and approach each other, and the first clamping plate 211 and the second clamping plate 212 are driven to move synchronously by the support vertical plates 218. As the support vertical plates 218 move, when the two second clamping plates 212 are in close contact with the side surfaces of the bearing seat, the position of the bearing seat is limited. As the support vertical plates 218 continue to move, the second clamping plates 212 are restricted by the bearing seat and remain in close contact with the side surfaces of the bearing seat. At the same time, under the restriction of the bearing seat, the first balancing link 216 and the second balancing link 217 are restricted by the second clamping plate 212, causing the two to rotate. The angle between them increases, and the transmission support frame 213 is driven by the first balancing link 216 to slide upward along the transmission guide rail 219, so that the return spring on the upper side of the transmission guide rail 219 is compressed and the return spring on the lower side of the transmission guide rail 219 is stretched; during the upward movement of the transmission support frame 213, the second transmission link 215 is driven to rotate, and the angle between the second transmission link 215 and the first transmission link 214 is reduced, thereby causing the two first clamping plates 211 to move further closer to each other until the two first clamping plates 211 are in close contact with the side surfaces of the bearing, so that the bearing is located directly above the bearing seat hole, and the bearing is pressed down by an external pressing device to complete the press-fitting of the bearing and the bearing seat.

[0033] For specific example three, please refer to Figure 5-6 On the basis of specific embodiment one and specific embodiment two, specifically, a transmission gear 302 is rotatably connected to one side of the hollow support seat 103, and the transmission gear 302 is engaged with the transmission rack 22. The transmission rack 22 moves synchronously with the corresponding support vertical plate 218, and drives the transmission gear 302 to rotate during the movement of the support vertical plate 218, and the upper surface of the adjustment support platform 101 is fixedly connected to the pushing guide rail 303 through the vertical support plate.

[0034] Furthermore, a transmission screw 304 is rotatably connected between the two inner walls of the pushing guide rail 303, the transmission screw 304 is fixedly connected to the transmission gear 302, and a pushing transmission block 305 that is threadably matched with the transmission screw 304 is slidably provided inside the pushing guide rail 303, and the pushing plate 301 is fixedly connected to the pushing transmission block 305 through a linkage rod.

[0035] The operation process of this embodiment is as follows: before placing the bearing seat, the two supporting vertical plates 218 are first moved synchronously to approach each other by one end distance, and the transmission rack 22 moves synchronously. Under the meshing action of the transmission rack 22 and the transmission gear 302, the transmission rack 22 rotates, driving the transmission screw 304 to rotate synchronously. Under the threaded cooperation of the transmission screw 304 and the push transmission block 305, the push transmission block 305 slides along the inside of the push guide rail 303, and the push plate 301 is driven to move synchronously by the linkage rod. Then, the bearing seat is placed on the hollow support seat 103. When the two supports 218 are in contact with each other, the transmission rack 22 rotates, driving the transmission screw 304 to rotate synchronously. As the support plates 218 continue to move closer to each other, the pusher plate 301 moves and gradually moves away from the bearing seat; when the press-fitting is completed, when the two support plates 218 move away from each other, the transmission rack 22 moves in the opposite direction, driving the transmission gear 302 to rotate in the opposite direction, and under the action of the threaded cooperation between the transmission screw 304 and the pusher transmission block 305, the pusher transmission block 305 slides along the inside of the pusher guide rail 303, and under the action of the linkage rod connection, drives the pusher plate 301 to move closer to the bearing seat until the press-fitted bearing seat and the bearing are pushed away from the hollow support seat 103, which is convenient for the next press-fitting operation.
