Description

Technical Field

[0001] The utility model relates to the technical field of bearing installation auxiliary equipment, and specifically relates to a device for efficiently and stably installing bearings. Background Technique

[0002] When a film is produced and prepared, longitudinal stretching is required. The longitudinal stretching process of the film and the functional film generally adopts a multi-point continuous stretching method. In the longitudinal stretching area, different speed ratios between different stretching rollers are required to achieve the longitudinal stretching of the film. Therefore, there are multiple stretching rollers and corresponding pressure rollers in the longitudinal stretching area to cooperate to achieve the longitudinal stretching of the film. Therefore, the stable operation of the rollers plays a crucial role in the stretching process. According to statistics, the average service life of the longitudinal stretching pressure rollers is about 2 months. If problems such as poor bearing installation occur, the rollers will be locked, resulting in the shutdown of the production line and causing great adverse effects on production.

[0003] To save costs, during actual use, used old rollers often need to be re-coated with rubber, reinstalled with bearings, lubricated and maintained, etc. However, the existing installation of roller bearings generally uses a hammer to knock manually to make the bearing snap into the bearing seat of the roller. However, with each knock of the hammer, the force point on the bearing is single, which will cause the bearing to be skewed during installation, making the center of the bearing inconsistent with the center of the roller and affecting the normal use of the roller. For this reason, we propose a device for efficiently and stably installing bearings. Content of the Utility Model

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] For this reason, the technical solution adopted by the utility model is as follows:

[0006] A device for efficiently and stably installing bearings, including a base, a support arm is installed on the top of the base, a lifting plate is slidably connected inside the support arm, a threaded rod is fixedly connected to the top of the lifting plate, an adjusting handwheel is threadedly connected to the outer surface of the threaded rod, and the adjusting handwheel is rotatably connected to the top of the support arm;

[0007] A driving component is installed on the lifting plate, a push plate is installed at the output end of the driving component, and a slider component is installed at the bottom of the push plate;

[0009] Based on the above technical solution, its working principle and the technical effects produced are:

[0010] In actual use, through the mutual cooperation of the set driving component, slider component, and mounting disc component, the bearing can be first installed on the mounting disc component, and then the mounting disc component is pushed to move smoothly, so that the bearing is evenly stressed around, and is smoothly and efficiently clamped into the roller, avoiding the deviation of the bearing causing the inconsistency between its axis and the center of the roller, which affects the normal use of the roller. And through the mutual cooperation of the set lifting plate, threaded rod, adjusting handwheel and other structures, the lifting plate can also be driven to move up and down, so that the use height of the push plate and the mounting seat component can be adjusted, facilitating the adaptation to rollers with different mounting heights.

[0011] In a preferred embodiment of the present invention, it can be further configured that: a plurality of self-locking rollers are installed at the bottom of the base.

[0012] In a preferred embodiment of the present invention, it can be further configured that: a guiding groove adapted to the lifting plate is provided on the inner wall of the support arm.

[0013] In a preferred embodiment of the present invention, it can be further configured that: the adjusting handwheel is rotationally connected to the top of the support arm through a bearing, and the adjusting handwheel is sleeved on the threaded rod.

[0014] In a preferred embodiment of the present invention, it can be further configured that: the driving component is set as a jack or a hydraulic cylinder for providing linear movement to the push plate.

[0017] In a preferred embodiment of the present invention, it can be further configured that: the mounting disc component includes an outer ring fixed to the end of the support column, and an inner ring is fixedly connected to the side wall of the outer ring away from the support column, and the diameter of the inner ring is smaller than that of the outer ring.

[0018] The explanations of the nouns, connecting words or adjectives involved in the above technical solutions are as follows:

[0019] Fixed connection means that after the parts or components are fixed, there is no relative movement connection. It is divided into two types: detachable connection and non-detachable connection.

[0020] (1) Detachable connection is to fix components together using screws, splines, wedge pins, etc. This connection method can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, and wedge pins), and they must be fastened properly.

[0021] (2) Non-detachable connections mainly refer to welding, riveting, and mortise fits, etc. Since forging, sawing, or oxygen cutting is required to disassemble during maintenance or replacement, spare parts generally cannot be used a second time. At the same time, during connection, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, polishing, etc.);

[0022] Movable connection means a connection with relative movement after fixing parts or components.

[0023] The above technical solutions of the present utility model have the following beneficial technical effects:

[0024] 1. In the present utility model, through the mutual cooperation of the driving component, slider component, and mounting disc component, the bearing can be first installed on the mounting disc component, and then the mounting disc component is pushed to move smoothly, so that the bearing is evenly stressed around and is smoothly and efficiently clamped into the roller, avoiding the situation that the axis of the bearing is inconsistent with the center of the roller due to the skew of the bearing, which affects the normal use of the roller.

[0025] 2. In the present utility model, through the mutual cooperation of the lifting plate, threaded rod, adjusting handwheel and other structures, the lifting plate can be driven to move up and down, so that the use height of the push plate and the mounting seat component can be adjusted, facilitating the adaptation to rollers with different mounting heights, and further improving the practicality of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0032] According to the concept of the present application, an embodiment of a device for efficiently and stably installing a bearing at the end of a roller is described herein in conjunction with Figures 1 to 3 Specifically, the device for efficiently and stably installing a bearing is configured as an integral structure, which has three components: a driving assembly 6, a slider assembly 8, and a mounting plate assembly 10. Through the mutual cooperation of the driving assembly 6, the slider assembly 8, and the mounting plate assembly 10 provided, the bearing can be first installed on the mounting plate assembly 10, and then the mounting plate assembly 10 is pushed to move smoothly, so that the bearing is evenly stressed around, and is stably and efficiently snapped into the roller, avoiding the situation that the axis of the bearing is inconsistent with the center of the roller due to the skew of the bearing, which affects the normal use of the roller. Through the mutual cooperation of the lifting plate 3, the threaded rod 4, the adjusting handwheel 5 and other structures provided, the lifting plate 3 can be driven to move up and down, so that the use height of the push plate 7 and the mounting seat assembly can be adjusted, facilitating the adaptation to rollers with different mounting heights, and further improving the practicability of the device.

[0033] In conjunction with Figures 1 - 3 As shown, a device for efficiently and stably installing a bearing provided by the present invention includes a base 1. A support arm 2 is installed on the top of the base 1. A lifting plate 3 is slidably connected inside the support arm 2. A threaded rod 4 is fixedly connected to the top of the lifting plate 3. An adjusting handwheel 5 is threadedly connected to the outer surface of the threaded rod 4, and the adjusting handwheel 5 is rotatably connected to the top of the support arm 2;

[0034] A driving assembly 6 is installed on the lifting plate 3. An output end of the driving assembly 6 is installed with a push plate 7, and a slider assembly 8 is installed at the bottom of the push plate 7;

[0035] A plurality of support columns 9 are slidably connected to the side wall of the lifting plate 3. An end of the support column 9 is fixedly connected to a mounting plate assembly 10.

[0036] A plurality of self-locking rollers 11 are installed at the bottom of the base 1. For the technical solution of this embodiment, the number of self-locking rollers 11 is set to four. The four self-locking rollers 11 are respectively installed at the four corners of the base 1. The provided self-locking rollers 11 can be used to move the device to an appropriate position as needed. For example, for some rollers that are not convenient to move, the appropriate installation position can be found by moving the position of the device.

[0037] For the technical solution of this embodiment, a guide groove 12 adapted to the lifting plate 3 is provided on the inner wall of the support arm 2. The provided guide groove 12 facilitates providing support and guidance for the lifting plate 3 when it moves. It should be noted that in actual use, the guide groove 12 can also be replaced with a guide rail, and guide wheels adapted to the guide rail are installed on both sides of the lifting plate 3. When the lifting plate 3 moves up and down, the guide wheels will move up and down in the guide rail, and in this way, the guiding function of the lifting plate 3 can also be realized.

[0038] Further, the adjusting handwheel 5 is rotationally connected to the top of the support arm 2 through a bearing, and the adjusting handwheel 5 is sleeved on the threaded rod 4. By rotating the adjusting handwheel 5, the meshing relationship between it and the threaded rod 4 can drive the threaded rod 4 to move up or down, thereby driving the lifting plate 3 to move up and down along the guide groove 12, and the use height of the push plate 7 and the mounting plate assembly 10 can be adjusted up and down, which is convenient for adapting to rollers with different diameters and different mounting heights.

[0039] The driving component 6 is set as a driving source for providing linear movement for the push plate 7. In some embodiments, the driving component 6 can be set as a jack or a hydraulic cylinder. This embodiment does not limit this and can be selected according to actual situations.

[0040] For the technical solution of this embodiment, the slider assembly 8 includes a slider 82 fixed to the bottom of the push plate 7 and a guide rail 81 fixed to the side wall of the lifting plate 3, and the guide rail 81 is slidably connected to the slider 82. The provided guide rail 81 and slider 82 facilitate providing support and guidance for the push plate 7 when it moves. Start the driving component 6 to push the push plate 7 towards the mounting plate assembly 10, and the mounting plate assembly 10 can smoothly snap the bearing into the bearing seat of the roller. It should be noted that the whole device has a certain weight, and the whole device will not shake when pushing the bearing for installation.

[0041] For the technical solution of this embodiment, the number of support columns 9 is set to four. One ends of the four support columns 9 are fixed to the mounting plate assembly 10, and the other ends penetrate through the lifting plate 3 and extend a certain length. A retaining ring (not shown in the figure) is also provided at the end of the support column 9 that penetrates through the lifting plate 3. When the push plate 7 pushes the mounting plate assembly 10 to move, the support column 9 will slide on the lifting plate 3, thereby providing support and guidance for the mounting plate assembly 10, and the provided retaining ring facilitates preventing the support column 9 from detaching from the lifting plate 3 when it slides.

[0042] For the technical solution of this embodiment, the push plate 7 and the mounting seat assembly are coaxially arranged. The mounting plate assembly 10 includes an outer ring 101 fixed to the end of the support column 9. A side wall of the outer ring 101 on the side away from the support column 9 is fixedly connected with an inner ring 102. The diameter of the inner ring 102 is smaller than that of the outer ring 101. When installing a bearing, first, the inner ring circular hole of the bearing is clamped at the position of the inner ring 102, and the sides of the inner and outer rings of the bearing are both abutted against the side wall of the outer ring 101. Then, the outer ring 101 is pushed to move by the push plate 7, so that the outer ring 101 and the inner ring 102 drive the bearing to be clamped into the bearing seat at the end of the roller. This facilitates the uniform force on all sides of the bearing during installation, and the bearing can be smoothly and efficiently clamped into the roller, avoiding the skew of the bearing, resulting in inconsistent axes of the bearing and the roller center, and affecting the normal use of the roller.

[0043] Specifically, when installing a bearing, first, the device is moved to an appropriate position by the self-locking rollers 11. Then, the adjusting handwheel 5 is rotated. Due to its meshing relationship with the threaded rod 4, the threaded rod 4 is driven to move up or down, thereby driving the lifting plate 3 to move up and down along the guide groove 12, so that the push plate 7 and the mounting plate assembly 10 are moved to an appropriate height to adapt to rollers with different installation heights. Then, the bearing to be installed is clamped on the inner ring 102, and the sides of the inner and outer rings of the bearing are both abutted against the side wall of the outer ring 101. Then, the driving assembly 6 is started to drive the push plate 7 to move towards the push plate 7 side, and the outer ring 101 is pushed to move by the push plate 7, so that the outer ring 101 and the inner ring 102 drive the bearing to be clamped into the bearing seat at the end of the roller. This facilitates the uniform force on all sides of the bearing during installation, and the bearing can be smoothly and efficiently clamped into the roller, avoiding the skew of the bearing, resulting in inconsistent axes of the bearing and the roller center, and affecting the normal use of the roller. After the installation is completed, at this time, the outer ring of the bearing is clamped into the bearing seat at the end of the roller. By pulling the support column 9 to drive the outer mounting ring 101 to move, it can be separated from the inner ring of the bearing. It should be noted that during installation, to avoid the movement of the roller, an external device can be used to fix the roller. How to fix it specifically is not limited in this embodiment.

[0044] Next, in combination with the drawings and embodiments, the device for efficiently and smoothly installing a bearing provided by the present invention will be further described.

[0045] A device for efficiently and smoothly installing a bearing includes a base 1. A support arm 2 is installed on the top of the base 1. A lifting plate 3 is slidably connected inside the support arm 2. A threaded rod 4 is fixedly connected to the top of the lifting plate 3. An adjusting handwheel 5 is threadedly connected to the outer surface of the threaded rod 4, and the adjusting handwheel 5 is rotatably connected to the top of the support arm 2;

[0046] A driving assembly 6 is installed on the lifting plate 3. An output end of the driving assembly 6 is installed with a push plate 7, and a slider assembly 8 is installed at the bottom of the push plate 7;

[0047] A plurality of support columns 9 are slidably connected to the side wall of the lifting plate 3, and the end of the support column 9 is fixedly connected with a mounting plate assembly 10.

[0048] The working principle and usage process of the present utility model are as follows: When it is necessary to install a bearing, first move the device to an appropriate position through the self-locking roller 11, and then rotate the adjusting handwheel 5. Utilize the meshing relationship between it and the threaded rod 4 to drive the threaded rod 4 to move upward or downward, thereby driving the lifting plate 3 to move up and down along the guide groove 12, so that the push plate 7 and the mounting plate assembly 10 move to an appropriate height, facilitating the adaptation to rollers with different installation heights. Then, the bearing to be installed is clamped on the inner ring 102, and the sides of the inner and outer rings of the bearing are both abutted against the side wall of the outer ring 101. Then, start the driving assembly 6 to drive the push plate 7 to move towards the push plate 7 side, and push the outer ring 101 through the push plate 7, so that the outer ring 101 and the inner ring 102 drive the bearing to be clamped into the bearing seat at the end of the roller. This is convenient for the bearing to be evenly stressed around during installation and smoothly and efficiently clamped into the roller, avoiding the bearing from being skewed, resulting in the axis not being consistent with the center of the roller and affecting the normal use of the roller. After the installation is completed, at this time, the outer ring of the bearing is clamped into the bearing seat at the end of the roller. By pulling the support column 9 to drive the outer ring 101 of the mounting to move, it can be separated from the inner ring of the bearing.
