Description

Technical Field

[0001] This utility model relates to the field of sprocket processing technology, and in particular to a sprocket press-in tool. Background Technology

[0002] When pressing sprockets, a sprocket press-in tool is often used. It is a tool specially designed to press sprockets in accurately and safely. Such sprocket press-in tools are widely used in mechanical assembly, automobile and motorcycle repair and other fields, which can improve work efficiency, reduce human error and ensure assembly quality.

[0003] A sprocket pressing fixture typically consists of a support base plate, a placement assembly, and a pressing mechanism. Therefore, during use, the support base plate provides a stable foundation, ensuring the entire fixture remains balanced and preventing tilting during operation. The placement assembly precisely positions the sprocket via an adjustment device and flexibly adjusts the support according to the sprocket's size, improving pressing accuracy. The pressing mechanism then presses the sprocket into place.

[0004] However, some existing devices use a simple mechanical pressing method and lack an effective pressure regulation and support mechanism. This can lead to the sprocket tilting or incomplete insertion during the pressing process, which makes it impossible to meet the requirements of high precision and high efficiency, and thus affects the performance and service life of the entire equipment. Therefore, a sprocket pressing fixture is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a sprocket pressing tool, which aims to improve the problem of uneven pressure during pressing in some existing devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sprocket pressing fixture includes a support base plate, a sprocket placement frame fixedly connected to the top of the support base plate, a placement component for extending and placing sprockets slidably connected inside the sprocket placement frame, two external support blocks fixedly connected to the outer sides of the placement component, a connecting rotating column rotatably connected inside each of the two external support blocks, a bidirectional support block fixedly connected to the outside of the placement component, one side of each of the two connecting rotating columns rotatably connected to the outer sides of the bidirectional support block, a rotating connecting column fixedly connected to the outside of the two connecting rotating columns, a bending inclined frame fixedly connected to the top of each rotating connecting column, and a bottom curved convex wheel fixedly connected to the bottom of each rotating connecting column.

[0008] As a further description of the above technical solution:

[0009] The placement assembly includes an extension adjustment rod, the outer side of which is slidably connected to the inside of the sprocket placement frame, and an extension placement frame is fixedly connected to the outer side of the extension adjustment rod. The outer rear sides of the bidirectional support block and the two bending rhombus frames are fixedly connected to the outer front side of the extension placement frame.

[0010] As a further description of the above technical solution:

[0011] Both sides of the outer side of the support base plate are provided with two sliding grooves, and the two sliding grooves are slidably connected to an internal sliding block.

[0012] As a further description of the above technical solution:

[0013] The outer side of the supporting base plate is provided with multiple rectangular insertion slots, and the outer side of the multiple rectangular insertion slots is at the top and bottom of the sliding slots at both ends;

[0014] As a further description of the above technical solution:

[0015] Both sides of the inner sliding block are slidably connected to alignment fixing blocks, and a double-ended connecting rod is fixedly connected to an adjacent side of the two alignment fixing blocks.

[0016] As a further description of the above technical solution:

[0017] An internal sliding column is slidably connected to the outer front side of the internal sliding block. The outer side of the internal sliding column passes through the double-ended connecting rod and the interior of the internal sliding block in sequence. An outer pushing rod is fixedly connected to the outer front side of the internal sliding block.

[0018] As a further description of the above technical solution:

[0019] The inner sliding block drives the outer pushing rod to slide inside the sliding grooves at both ends, causing one side of the outer pushing rod to be pushed out.

[0020] As a further description of the above technical solution:

[0021] The bottom curved convex wheel is designed in a semi-cylindrical shape. By bending the rotating connecting column through the bending rhomboid frame, the bottom curved convex wheel can be driven to change angle, thereby applying pressure to the sprocket and pressing it in.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, after the inclined frame is bent to drive the rotating connecting column to rotate, the bottom curved convex wheel can press the surface of the sprocket, so that the bottom curved convex wheel applies pressure to the surface of the sprocket. This design effectively improves the uniformity of pressing, achieves a more precise pressing effect, and reduces potential damage caused by unbalanced pressure.

[0024] 2. In this utility model, the inner sliding block drives the outer pushing rod to push out the rear side of the extension placement frame. Then, the alignment fixing block slides into the rectangular insertion slot to fix it, preventing the sprocket from shifting or tilting during the pressure process, thus improving the safety and accuracy of the operation.

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2The present invention provides an embodiment of a sprocket pressing fixture, comprising a support base plate 1, a sprocket placement frame 2 fixedly connected to the top of the support base plate 1, the sprocket placement frame 2 being used to support the sprocket, a placement assembly for extending the placement of the sprocket being slidably connected inside the sprocket placement frame 2, the placement assembly including an extension adjustment rod 3, the length of which can be conveniently adjusted as needed, the extension adjustment rod 3 being slidably connected to the outside of the sprocket placement frame 2, an extension placement frame 4 being fixedly connected to the outside of the extension adjustment rod 3, the extension placement frame being used to provide additional support, a bidirectional support block 7 and two bending rhomboid frames 8 being fixedly connected to the outside of the front of the extension placement frame 4, and two external support blocks 5 being fixedly connected to the outside of the placement assembly, which can provide good support performance on both sides of the extension placement frame 4;

[0033] Both external support blocks 5 are rotatably connected to connecting rotating columns 6, which are designed to provide good rotation performance. The external components are fixedly connected to bidirectional support blocks 7, which provide support and stability. The two connecting rotating columns 6 are rotatably connected to the two external sides of the bidirectional support blocks 7. The two connecting rotating columns 6 are fixedly connected to rotating connecting columns 9, which help to press the sprocket in by providing rotation. The top of the rotating connecting column 9 is fixedly connected to a bending rhombus frame 8, which can rotate the rotating connecting column 9 by bending the rhombus frame 8. The bottom of the rotating connecting column 9 is fixedly connected to a bottom curved convex wheel 10, which is designed to be semi-cylindrical. By bending the rhombus frame 8 to bend the rotating connecting column 9, the bottom curved convex wheel 10 can be driven to change angle, thereby applying pressure to the sprocket and pressing it in.

[0034] Reference Figure 3 and Figure 4The support base plate 1 has two sliding grooves 11 on both outer sides, which provide good sliding performance. Internal sliding blocks 13 are slidably connected inside the two sliding grooves 11, providing good sliding ability when sliding inside the sliding grooves 11. Multiple rectangular insertion slots 12 are evenly distributed on both outer sides of the support base plate 1, with the outer sides of the rectangular insertion slots 12 at the top and bottom of the sliding grooves 11. Alignment fixing blocks 14 are slidably connected to both outer sides of the internal sliding blocks 13, allowing them to slide into the rectangular insertion slots 12. The two alignment fixing blocks 14... A double-ended connecting rod 15 is fixedly connected to the adjacent side of the inner sliding block 13. The inner sliding block 13 is slidably connected to an inner sliding column 16 on its outer front side. The inner sliding column 16 can drive the double-ended connecting rod 15 to slide out, thereby driving the alignment fixing block 14 to slide out. The outer side of the inner sliding column 16 passes through the double-ended connecting rod 15 and the inner sliding block 13 in sequence. An outer pushing rod 17 is fixedly connected to the outer front side of the inner sliding block 13. After being pushed by the outer pushing rod 17, the extended distance of 4 can be fixed. The inner sliding block 13 drives the outer pushing rod 17 to slide inside the sliding grooves 11 at both ends, so that one side of the outer pushing rod 17 is pushed out.

[0035] Working principle: First, the operator places the sprocket to be pressed into the sprocket placement frame 2, ensuring that the sprocket is firmly fixed inside the frame. Then, the extension adjustment rod 3 is adjusted in length according to the size and needs of the sprocket to match the thickness of the sprocket. At this time, the extension placement frame 4 will also be adjusted accordingly to provide additional support to ensure that the sprocket does not shift during the pressing process. The rotation connection of the external support block 5 and the connecting rotating column 6 achieve smooth rotation. This process allows the bidirectional support block 7 to provide stable support, ensuring that the whole device is not easy to tilt, while maintaining the stability of the sprocket. By pushing and bending the slanted frame 8, the rotating connecting column 9 begins to rotate, thereby driving the bottom curved convex wheel 10 to gradually contact the surface of the sprocket. With the continuous operation of bending the slanted frame 8, the angle change of the bottom curved convex wheel 10 causes the sprocket to be subjected to gradually increasing pressure, and finally the sprocket is accurately pressed into the required position.

[0036] When adjusting the length of the sprocket placement frame 2, the operator places the support base plate 1 on the workbench as needed, ensuring the stability of the support base plate 1. Next, the sprocket to be pressed is placed on the sprocket placement frame 2. During this process, the internal sliding blocks 13 in the two end sliding grooves 11 begin to work. The operator can manually adjust the position of the internal sliding blocks 13, allowing them to slide freely in the end sliding grooves 11. When the internal sliding blocks 13 reach the predetermined position, the alignment fixing blocks 14 begin to function, and the two alignment fixing blocks 14 and... The rectangular insertion slot 12 contacts and slides into it, which ensures the fixation of the sprocket placement frame 2 and provides the necessary stability. Subsequently, the inner sliding column 16 drives the double-end connecting rod 15 to move through the sliding action, so that the alignment fixing block 14 slides in the rectangular insertion slot 12 and is kept in the right position. At the same time, the outer push rod 17 is also connected to the inner sliding block 13. As the inner sliding block 13 moves, the outer push rod 17 also slides along the inside of the sliding slots 11 at both ends and pushes outward to support and fix the extension placement frame 4.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
