Description

Technical Field

[0001] This utility model relates to the field of bushing assembly technology, and in particular to a convenient device for fitter to assemble bushings. Background Technology

[0002] In the process of assembling bushings by fitters, the traditional method is to manually align the bushings with the mounting positions on the equipment.

[0003] Due to the lack of an effective guiding device, the bushing needs to be initially guided by hand when installing it onto the equipment, which is quite dangerous. Therefore, there is a need for a device for fitter assembly of bushings that is easy to operate and improves assembly accuracy and efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the bushing needs to be manually guided during installation due to the lack of an effective guiding device, which is quite dangerous. Therefore, this invention proposes a convenient and easy-to-operate device for assembling bushings by fitters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A convenient fitter's assembly device for bushings includes a base, a mounting bracket fixed to the top of the base, a cylinder fixed to the top of the mounting bracket, and a pressure plate for pressing the bushing assembly fixed to the output end of the cylinder.

[0007] The top of the base is fixed with two mounting seats, and the same connecting plate is installed on the two mounting seats. The top of the connecting plate is fixed with a limiting cylinder, which is used to place the bushing to be assembled and limit its position. The upper side of the connecting plate is provided with a bushing guide post, which slides with the inner wall of the bushing to guide and limit the bushing to be assembled.

[0008] In order not to hinder the pressing and assembly of the pressure plate, a set of elastic support components is provided between the connecting plate and the bushing guide post. The elastic support components are used to drive the bushing guide post to move downward when the pressure plate is pressed down to avoid affecting the pressing and assembly of the pressure plate.

[0009] In one possible design, the elastic support assembly includes two receiving slots formed within a connecting plate, two connecting rods slidably disposed within the connecting plate, the two connecting rods respectively located within the two receiving slots, the top ends of the two connecting rods being fixed with the same threaded post, a bushing guide post located on the threaded post, a set of connecting components provided between the bushing guide post and the threaded post, springs being fitted onto the surfaces of the two connecting rods, the two ends of the two springs respectively abutting against the side ends of the threaded post and the inner walls of the two receiving slots via spring seats, and the bottom ends of the two connecting rods being fixed with the same limiting plate;

[0010] The spring pushes the threaded post and the bushing guide post upwards, pushing the bushing guide post to a position higher than the inclined groove, so that the bushing can be fitted onto the surface of the bushing guide post.

[0011] In one possible design, the top of the bushing guide post is rounded to facilitate placing the bushing on the surface of the bushing guide post.

[0012] In one possible design, the connecting assembly includes a threaded groove formed at the bottom end of the bushing guide post, the threaded groove being threadedly connected to the surface of the threaded post.

[0013] In one possible design, the inner wall of the limiting cylinder is provided with a sloping groove, which is used to facilitate the placement of the equipment to be assembled with the bushing.

[0014] In one possible design, the bushing guide post and the limiting cylinder are on the same horizontal line, and the height of the bushing guide post is lower than the height of the limiting cylinder.

[0015] In this application, the pressure plate is pushed downward by the cylinder to contact the bushing and assemble the bushing into the equipment to be assembled.

[0016] The spring pushes the threaded post and bushing guide post upwards, pushing the bushing guide post to a position higher than the inclined groove, so that the bushing can be fitted onto the surface of the bushing guide post. After the pressure of the pressure plate is applied, the guide post will be pushed back automatically by the spring for the next bushing fitting.

[0017] Beneficial effects: The device for easy-to-operate fitter assembly of bushings described in this utility model, by setting bushing guide posts and slidingly engaging the bushing guide posts with the inner wall of the bushing, can accurately guide the bushing during assembly, effectively ensuring the coaxiality of the bushing and the equipment mounting hole, greatly improving assembly accuracy, reducing the problem of bushing and equipment damage caused by assembly misalignment, and improving product quality.

[0018] In this utility model, a convenient fitter assembly bushing device is provided. The device is equipped with a cylinder and a pressure plate. The cylinder can provide stable and large pressure, and the pressure plate can accurately and quickly press the bushing into the equipment without the need for manual application of large pressure, thereby reducing the labor intensity of workers and improving assembly efficiency.

[0019] In this invention, the design of the elastic support component enables the bushing guide column to move downward when the pressure plate presses down on the bushing, thus preventing the bushing guide column from obstructing the pressure plate 4 from squeezing the assembly and ensuring the smooth progress of the assembly process. After the assembly is completed, the spring can restore its elasticity and push the bushing guide column back to its initial position, facilitating the next assembly operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In one embodiment: Refer to Figures 1-2 A user-friendly fitting device for assembling bushings, applicable in the field of bushing assembly technology, includes a base 1 horizontally placed on a workbench. A mounting bracket 2, which is bolted to the top of the base 1, has an inverted "L" shape. A cylinder 3 is bolted to the top of the mounting bracket 2. The output end of the cylinder 3 faces downwards, and a pressure plate 4, a flat plate structure, is bolted to the output end for pressing and assembling the bushing.

[0025] Two mounting seats 5 are bolted to the top of the base 1. The two mounting seats 5 are arranged in parallel, and the same connecting plate 6 is bolted to the two mounting seats 5. The top of the connecting plate 6 is bolted to the limiting cylinder 7. The limiting cylinder 7 is a cylindrical structure with an inclined groove 8 on its inner wall. The inclined angle of the inclined groove 8 is 30-60 degrees, which is used to facilitate the placement of the equipment to be assembled with the bushing and to limit the movement of the equipment.

[0026] A bushing guide post 9 is provided on the upper side of the connecting plate 6. The bushing guide post 9 has a cylindrical structure with rounded corners at its top. The radius of the rounded corners is 1-3 mm to facilitate the bushing being fitted onto the surface of the bushing guide post 9. The bushing guide post 9 slides in contact with the inner wall of the bushing and is used to guide and limit the bushing to be assembled.

[0027] To avoid hindering the pressing and assembly of the pressure plate 4, a set of elastic support components is provided between the connecting plate 6 and the threaded groove 10. The elastic support components include two accommodating grooves 14 symmetrically distributed within the connecting plate 6. Two connecting rods 12 are slidably disposed within the connecting plate 6, each located within one of the accommodating grooves 14. The top ends of the two connecting rods 12 are bolted to the same threaded post 11. A bushing guide post 9 is located on the threaded post 11, and the bushing guide post 9 and the threaded post 11 are connected by a connecting component. The connecting component consists of a threaded groove 10 at the bottom end of the bushing guide post 9, which is threadedly connected to the surface of the threaded post 11.

[0028] Springs 13 are fitted onto the surfaces of both connecting rods 12. The wire diameter of the springs 13 is 2-5 mm. The two ends of the two springs 13 abut against the side ends of the threaded post 11 and the inner walls of the two receiving grooves 14, respectively, through spring seats. The bottom ends of the two connecting rods 12 are fixed to the same limiting plate 15 by bolts. The limiting plate 15 is used to limit the range of movement of the connecting rods 12.

[0029] During operation, the elasticity of spring 13 pushes the threaded post 11 and bushing guide post 9 upwards, raising the bushing guide post 9 to a position above the inclined groove 8 with a height difference of 5-10 mm, facilitating the fitting of the bushing onto the surface of the bushing guide post 9. The equipment to be fitted with the bushing is placed inside the limiting cylinder 7, and then the bushing is fitted onto the bushing guide post 9. The cylinder 3 is activated, and its output end drives the pressure plate 4 downwards, contacting and pressing the bushing. During this pressing process, the bushing guide post 9 is subjected to pressure, which compresses the spring 13 via the connecting rod 12, causing the bushing guide post 9 to move downwards, thus avoiding interference with the pressing assembly of the pressure plate 4. After the bushing is fitted, the cylinder 3 moves the pressure plate 4 upwards, the spring 13 regains its elasticity, pushing the threaded post 11 and bushing guide post 9 upwards back to their initial positions.

[0030] In another embodiment: Refer to Figures 1-2 An improvement based on Example 1 is made: the bushing guide post 9 and the limiting cylinder 7 are on the same horizontal line, and the height of the bushing guide post 9 is lower than the height of the limiting cylinder 7 by 3-8 mm, so as to ensure that the bushing guide post 9 can accurately guide the bushing during the assembly process, while not affecting the limiting function of the limiting cylinder 7 on the equipment.

[0031] However, as is well known to those skilled in the art, the working principle and wiring method of cylinder 3 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0032] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
