Description

Technical Field

[0001] This utility model relates to the field of bearing bushing processing technology, and in particular to a bearing bushing processing device with a positioning mechanism. Background Technology

[0002] A bearing is a type of bearing that rubs against a shaft during operation. Due to its advantages such as smooth operation, reliability, no noise, and low cost, it is often used in high-speed and light-load conditions. It is an important component in bearing bushings and sliding bearings. The assembly of the bearing and bushing generally relies on the interference fit between the bushing and the bearing.

[0003] In the process of machining bearing bushings, in order to improve the stability and service life of the machined bearing bushings, it is necessary to grind and remove the burrs from the bearing bushings.

[0004] Traditional bushing grinding equipment typically involves placing the bushing on a support column and then applying external pressure to fix the bushing before grinding. This method cannot provide multi-directional positioning and support for bushings of different specifications, which can easily cause the bushing to wobble during grinding and thus lead to grinding misalignment, rendering the bushing unusable. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a bearing bushing processing device with a positioning mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bearing bushing processing device with a positioning mechanism, comprising a processing table, wherein a cylinder is provided on the upper outer surface of the processing table, and the output end of the cylinder extends into the interior of the processing table and is connected to a grinding component; a motor is provided on one outer surface of the processing table, and the output end of the motor extends into the interior of the processing table and is fixedly connected to a connecting frame; a cylinder is provided on one side of the connecting frame, and a support plate is fixedly connected to the output end of the cylinder;

[0007] A connecting column is fixedly connected to the middle of one side of the outer surface of the support plate, and several sets of support plates are annularly hinged around the outer surface of the support plate. Support components for positioning bushings of different specifications are provided between the several sets of support plates and the connecting column.

[0008] Furthermore, the support assembly includes a limiting ring, a guide rod, and a spring; a limiting ring is provided between several sets of support plates, and a guide rod is fixedly connected to the outer surface of the limiting ring near the support plate. One end of the guide rod passes through to one side of the support plate and is movably connected thereto. A spring is provided on the outer surface of the guide rod at a position between the support plate and the limiting ring. One end of the spring is fixedly connected to the limiting ring, and the other end is fixedly connected to the support plate.

[0009] Furthermore, a groove is provided on the outer surface of the connecting column at the position corresponding to the support plate, and a guide column is fixedly connected inside the groove. A slider and a second spring are movably connected to the outside of the guide column, and one end of the second spring is fixedly connected to the slider and the other end is fixedly connected to the groove.

[0010] Furthermore, one end of the slider extends through the outside of the groove and is hinged to a support rod, with one end of the support rod hinged to the slider and the other end hinged to the corresponding support plate, the outer surface of which is arc-shaped.

[0011] Furthermore, the outer surfaces of several sets of support plates are fixedly connected with limit strips, and the cross-section of the limit strips is semi-arc-shaped. The outer surfaces of each set of limit strips are fixedly connected with several sets of limit pieces, and the inner surface of the limit ring is in contact with the limit pieces.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] In this utility model, by setting a limiting ring, a support plate and a support rod in combination, the limiting ring and the limiting plate can support and limit the bushing from both ends under the action of spring one and spring two, respectively, so as to position and fix bushings of different specifications, thereby ensuring the stability of the bushing during the processing.

[0014] In addition, by setting a limiting strip on the surface of the limiting plate, it can not only support the connecting column in a direction perpendicular to the axis of the connecting column, but also prevent the bushing from sliding in the axis of the connecting column, thereby further improving the machining accuracy of the bushing.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: As Figure 1 and Figure 2 As shown, the present invention proposes a bearing bushing processing device with a positioning mechanism, including a processing table 1. A cylinder 2 is provided on the upper outer surface of the processing table 1, and the output end of the cylinder 2 extends into the interior of the processing table 1 and is connected to a grinding component 3. The cylinder 2 drives the grinding component 3 to move down to grind the surface of the bushing. A motor 4 is provided on one outer surface of the processing table 1, and the output end of the motor 4 extends into the interior of the processing table 1 and is fixedly connected to a connecting frame. A cylinder 5 is provided on one side of the connecting frame, and a support plate 6 is fixedly connected to the output end of the cylinder 5. The motor 4 drives the support plate 6 to rotate the bushing, thereby performing all-round processing on the bushing.

[0023] A connecting column 7 is fixedly connected to the middle of one side of the outer surface of the support plate 6, and several sets of support plates 8 are hinged in a ring around the outer surface of the support plate 6. Support components 9 are provided between the several sets of support plates 6 and the connecting column 7 for positioning bushings of different specifications. The support components 9 support and position the bushings to ensure the stability of the bushings during the processing.

[0024] Example 2: Figure 2-5As shown, the difference between this embodiment and embodiment 1 is that a limiting ring 91 is provided between several sets of support plates 8, and a guide rod 92 is fixedly connected to the side of the outer surface of the limiting ring 91 near the support plate 6. One end of the guide rod 92 passes through to one side of the support plate 6 and is movably connected to it. A spring 93 is provided on the outer surface of the guide rod 92 at the position between the support plate 6 and the limiting ring 91. One end of the spring 93 is fixedly connected to the limiting ring 91, and the other end is fixedly connected to the support plate 6. When the bushing is not installed on the surface of the support plate 8, the limiting ring 91 is located outside the support ring and away from the support plate 6 under the action of the spring 93. One end of the bushing is put on several sets of support plates 8 and pushed towards the support plate 6.

[0025] A groove 94 is provided on the outer surface of the connecting column 7 at the position corresponding to the support plate 8, and a guide column 95 is fixedly connected inside the groove 94. A slider 97 and a spring 96 are movably connected to the outside of the guide column 95, and one end of the spring 96 is fixedly connected to the slider 97 and the other end is fixedly connected to the groove 94.

[0026] One end of the slider 97 extends through the outside of the slide groove 94 and is hinged to a support rod 98. One end of the support rod 98 is hinged to the slider 97, and the other end is hinged to the corresponding support plate 8. The outer surface of the support plate 8 is arc-shaped. As the bushing pushes towards the support plate 6, the slider 97 pushes the support rod 98 to support the support plate 8 under the action of the spring 96. The support plate 8 rotates away from the connecting column 7 until one end of the bushing abuts against the limiting strip 99. The support plate 8 supports the bushing in a direction perpendicular to the axis of the connecting column 7.

[0027] Several sets of support plates 8 are fixedly connected to the outer surface of each set of support plates 8, and the cross-section of the limit strip 99 is semi-arc. Several sets of limit pieces 910 are fixedly connected to the outer surface of each set of limit strip 99. The limit pieces 910 abut against the bushing. The inner surface of the limit ring 91 is in contact with the limit piece 910. The limit strip 99 and the limit piece 910 abut against the bushing in the axial direction of the connecting column 7.

[0028] The working process and principle of this utility model are as follows:

[0029] Step 1: When the bushing is not installed on the surface of the support plate 8, the limiting ring 91 is located at the end outside the support ring away from the support plate 6 under the action of the spring 93. The limiting ring 91 tightens several sets of support plates 8, and then one end of the bushing is put on several sets of support plates 8 and pushed towards the limiting ring 91.

[0030] Step 2: As the bushing pushes the slider 97 towards the support plate 6, the spring 96 pushes the support rod 98 to support the support plate 8. The support plate 8 rotates away from the connecting column 7 until one end of the bushing abuts against the limiting strip 99. The support plate 8 supports the bushing in a direction perpendicular to the axis of the connecting column 7. The limiting strip 99 and the limiting piece 910 abut against the bushing from the axial direction of the connecting column 7.

[0031] Step 3: Control cylinder 2 to drive the grinding part 3 to move down and grind the bushing surface. During this process, motor 4 drives support plate 6 to rotate the bushing, thereby processing the bushing in all directions. By controlling the operation of cylinder 2 5, the corresponding position of the bushing and the grinding part 3 can be adjusted.

[0032] 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 inventive concept of the present utility model, should be included within the protection scope of the present utility model.
