Description

Technical Field

[0001] This utility model relates to the field of bearing hole processing technology, and in particular to a boring bar mounting structure for machining bearing holes in a vertical compressor crankcase. Background Technology

[0002] The boring bar mounting structure for machining crankcase bearing holes of vertical compressors is a device used to mount boring tools. The boring bar is usually mounted on a boring machine or boring machine to achieve boring of the bearing holes at both ends or in the middle of the crankcase and to ensure that the machined bearing holes have a high degree of coaxiality.

[0003] The existing boring bar mounting structure installed on the boring machine has the special characteristics of boring machining for workpieces of specific types or sizes, which allows the boring machine to perform special machining according to the size of the crankcase, which helps to improve machining efficiency.

[0004] However, in practical applications, existing boring bar mounting structures are usually designed for crankcase bearing holes of specific sizes. When different sizes of bearing holes need to be machined, it is often necessary to replace the entire boring bar or make a lot of adjustments, which is not flexible enough and does not help to improve the versatility of the boring bar mounting structure.

[0005] Therefore, this application provides a boring bar mounting structure for machining crankcase bearing holes of a vertical compressor to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a boring bar installation structure for machining crankcase bearing holes in vertical compressors.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a boring bar mounting structure for machining crankcase bearing holes in a vertical compressor, comprising:

[0008] Boring row body;

[0009] An adjustment assembly is provided at both ends of the boring bar body. The adjustment assembly includes collars at both ends of the boring bar body. Fixed push plates are provided on the opposite sides of the two collars. The fixed push plates are arranged in a circular array on the collars along the central axis of the boring bar body. The side of the fixed push plate closest to the boring bar body has an arc-shaped structure. A limit block is fixedly connected to the side of the fixed push plate closest to the collar. The fixed push plate is slidably connected to the collar through the limit block.

[0010] A transmission assembly is provided, which is located at both ends of the boring bar body and serves to support the boring bar body while providing support for the fixed push plate. The transmission assembly includes transmission brackets located at both ends of the boring bar body. A hydraulic telescopic rod is fixedly connected to the side of the transmission bracket near the fixed push plate. A movable push plate is provided on the output end of the hydraulic telescopic rod. The movable push plate is movably connected to the boring bar body and is drively connected to the fixed push plate.

[0011] Furthermore, both sides of the collar are threaded with threaded posts.

[0012] The beneficial effects of adopting the above-mentioned further solution are: setting the collar as a semi-circular structure, installing a threaded groove on the collar that matches the threaded post, and threading the threaded post inside the two collars, thereby facilitating the fixing of the collar and improving the stability of the collar.

[0013] Furthermore, the fixed push plate has an anti-slip coating on the side away from the boring bar body.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the anti-slip coating can increase the friction between the fixed push plate and the bearing hole, ensuring the stability of the fixed push plate during use.

[0015] Furthermore, a connecting bearing is fixedly connected to one end of the boring bar body near the collar.

[0016] The beneficial effects of adopting the above-mentioned further solutions are: ensuring the smoothness of the boring bar body during rotation, and at the same time, adapting to crankcases of different lengths, further improving the versatility of the boring bar mounting structure.

[0017] Furthermore, a snap-fit ​​block is fixedly connected to the side of the connecting bearing near the collar, and the collar is fixedly connected to the connecting bearing through the snap-fit ​​block.

[0018] The beneficial effect of adopting the above-mentioned further solution is that it fixes the collar to the outer ring of the connecting bearing, thereby improving the stability of the collar after installation.

[0019] Furthermore, a buckle is fixedly connected to the side of the movable push plate near the hydraulic telescopic rod, and a slot matching the buckle is opened at the output end of the hydraulic telescopic rod. The movable push plate is fixedly connected to the output end of the hydraulic telescopic rod through the buckle and the slot.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the buckles on both sides of the movable push plate are engaged with the output end of the hydraulic telescopic rod, thereby facilitating the adjustment and fixation of the movable push plate.

[0021] Furthermore, an elastic fixing block is fixedly connected inside the card slot, and the buckle is engaged with the card slot through the elastic fixing block.

[0022] The beneficial effect of adopting the above-mentioned further solution is that when the buckle is engaged inside the slot, the compressed elastic fixing block engages inside the slot through its own elasticity, thus fixing the slot and the buckle.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] 1. By setting an adjustment component, the collar is provided with a limiting groove that matches the limiting block. When the fixed push plate is pushed, the fixed push plate slides on the collar along the limiting groove with the help of the limiting block. The limiting block and the limiting groove cooperate with each other to effectively limit the sliding path of the fixed push plate. After the collar and the boring bar body are installed inside the crankcase, the fixed push plate moves towards the inner wall of the bearing hole under force. Since the outer side of the fixed push plate is an arc-shaped structure, it can fit tightly against the inner wall of the bearing hole, and the boring bar body is firmly fixed in the crankcase from multiple directions. This allows the boring bar body to be adapted and installed in crankcase bearing holes of different diameters, effectively solving the problem that in the past, when machining bearing holes of different sizes, it was often necessary to replace the entire boring bar or make a lot of adjustments, resulting in insufficient flexibility. This improves the versatility of the boring bar installation structure.

[0025] 2. By setting up a transmission assembly, hydraulic telescopic rods are installed on both sides of the transmission bracket, ensuring that the central axis of the movable push plate installed on the hydraulic telescopic rod is aligned with the central axis of the boring bar body. When the hydraulic telescopic rod is activated, it pushes the movable push plate towards the fixed push plate. Because the sides of the hydraulic telescopic rod and the fixed push plate that are close to each other are mutually compatible arc surfaces, the movable push plate will push the fixed push plate to move along the arc surface during the movement. During this process, the fixed push plate and the limit block work together to ensure that the fixed push plate unfolds smoothly, thereby fixing the boring bar body inside the bearing hole. This ensures that the fixed push plate can only unfold outward along the central axis of the boring bar body, improving support for the fixed push plate while maintaining its stability during use.

[0035] 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.

[0036] like Figures 1-5 As shown, this utility model provides a technical solution: a boring bar mounting structure for machining crankcase bearing holes of a vertical compressor, comprising: a boring bar body 1, the boring bar body 1 being composed of a boring bar, a cutter head, and a cutter body, the cutter head being mounted on the boring bar and providing installation and fixing space for the cutter body;

[0037] like Figures 2-4 As shown, the adjustment component 2 is located at both ends of the boring bar body 1. The adjustment component 2 includes collars 21 located at both ends of the boring bar body 1. Fixed push plates 22 are provided on the opposite sides of the two collars 21. The fixed push plates 22 are arranged in a circular array on the collars 21 along the central axis of the boring bar body 1. The side of the fixed push plate 22 closest to the boring bar body 1 has an arc-shaped structure. A limit block 23 is fixedly connected to the side of the fixed push plate 22 closest to the collars 21. The fixed push plate 22 is slidably connected to the collars 21 through the limit block 23.

[0038] like Figures 2-5As shown, the transmission assembly 3 is located at both ends of the boring bar body 1 and serves to support the boring bar body 1 while also providing support for the fixed push plate 22. The transmission assembly 3 includes transmission brackets 31 located at both ends of the boring bar body 1. A hydraulic telescopic rod 33 is fixedly connected to the side of the transmission bracket 31 near the fixed push plate 22. A movable push plate 32 is provided on the output end of the hydraulic telescopic rod 33. The movable push plate 32 is movably connected to the boring bar body 1 and is drively connected to the fixed push plate 22. This is achieved by opening a matching limit block 23 on the collar 21. The matching limiting groove allows the fixed push plate 22 to slide along the limiting groove on the collar 21 via the limiting block 23 when the fixed push plate 22 is pushed. This limiting block 23, in conjunction with the limiting groove, restricts the sliding path of the fixed push plate 22. After the collar 21 and the boring bar body 1 are installed inside the crankcase, the fixed push plate 22 moves towards the inner wall of the bearing hole under force. Because the outer side of the fixed push plate 22 has an arc-shaped structure, it fits against the inner wall of the bearing hole, thus fixing the boring bar body 1 inside the crankcase from multiple directions, allowing the boring bar body 1 to adapt to... The boring bar is fitted and installed on the crankcase bearing bores of different diameters, solving the problem of insufficient flexibility when machining bearing bores of different sizes, which often requires replacing the entire boring bar or performing extensive adjustments. This improves the versatility of the boring bar mounting structure. A transmission bracket 31 is installed on a standard workbench, supporting the boring bar body 1 from both ends. Simultaneously, hydraulic telescopic rods 33 are installed on both sides of the transmission bracket 31, and the central axis of the movable push plate 32 mounted on the hydraulic telescopic rod 33 is aligned with the central axis of the boring bar body 1. Qi, start the hydraulic telescopic rod 33. The hydraulic telescopic rod 33 pushes the movable push plate 32 to move towards the fixed push plate 22. Since the sides of the hydraulic telescopic rod 33 and the fixed push plate 22 that are close to each other are matching arc surfaces, the movable push plate 32 will push the fixed push plate 22 to move along the arc surface when it moves. It will cooperate with the limit block 23 to ensure that the fixed push plate 22 unfolds and fixes the boring bar body 1 inside the bearing hole. This ensures that the fixed push plate 22 can only unfold outward along the central axis of the boring bar body 1, thus ensuring the stability of the fixed push plate 22 during use.

[0039] Furthermore, such as Figure 4 As shown, threaded posts 26 are threaded to both sides of the collar 21. By setting the collar 21 into a semi-circular structure and installing the two collars 21 on the boring bar body 1 from the top and bottom, it is convenient to install and remove the collar 21. Threaded grooves that match the threaded posts 26 are installed on the collar 21, and the threaded posts 26 are threaded into the inside of the two collars 21, which facilitates the fixing of the collar 21 and improves the stability of the collar 21.

[0040] Furthermore, such as Figure 3As shown, an anti-slip coating 27 is provided on the side of the fixed push plate 22 away from the boring bar body 1. By spraying the anti-slip coating 27 on the outside of the fixed push plate 22, when the fixed push plate 22 comes into contact with the inner wall of the bearing hole, the anti-slip coating 27 can increase the friction between the fixed push plate 22 and the bearing hole, ensuring the stability of the fixed push plate 22 during use.

[0041] Furthermore, such as Figure 3 As shown, a connecting bearing 24 is fixedly connected to one end of the boring bar body 1 near the collar 21. By installing the connecting bearing 24 between the collar 21 and the boring bar body 1, the smoothness of the boring bar body 1 during rotation is ensured. At the same time, by adjusting the position of the connecting bearing 24 on the boring bar body 1, the position of the collar 21 installed inside the crankcase can be adjusted, thereby adapting to crankcases of different lengths and further improving the versatility of the boring bar mounting structure.

[0042] Furthermore, such as Figure 3 As shown, a snap-fit ​​block 25 is fixedly connected to the side of the connecting bearing 24 near the collar 21. The collar 21 is fixedly connected to the connecting bearing 24 through the snap-fit ​​block 25. By opening a snap-fit ​​groove on the collar 21 that matches the snap-fit ​​block 25, when the collar 21 is installed on the connecting bearing 24, the snap-fit ​​block 25 snaps into the inside of the snap-fit ​​groove, so that the collar 21 is fixed to the outer ring of the connecting bearing 24, thereby improving the stability of the collar 21 after installation.

[0043] Furthermore, such as Figure 5 As shown, a buckle 34 is fixedly connected to the side of the movable push plate 32 near the hydraulic telescopic rod 33. The output end of the hydraulic telescopic rod 33 has a slot 35 that matches the buckle 34. The movable push plate 32 is fixedly connected to the output end of the hydraulic telescopic rod 33 through the buckle 34 and the slot 35. By making the slots 35 on both sides mirror each other in the horizontal direction, the openings of the slots 35 face opposite directions. When the movable push plate 32 rotates on the transmission bracket 31, the buckles 34 on both sides of the movable push plate 32 engage with the output end of the hydraulic telescopic rod 33, thereby facilitating the adjustment and fixation of the movable push plate 32.

[0044] Furthermore, such as Figure 5 As shown, an elastic fixing block 36 is fixedly connected inside the slot 35. The buckle 34 is engaged with the slot 35 through the elastic fixing block 36. By opening a slot on the buckle 34 that matches the elastic fixing block 36, when the buckle 34 moves toward the slot 35, the buckle 34 squeezes the elastic fixing block 36. After the buckle 34 is engaged inside the slot 35, the squeezed elastic fixing block 36 is engaged inside the slot through its own elasticity, thus fixing the slot 35 and the buckle 34.

[0045] Working principle: such as Figures 1-5As shown, first, the transmission bracket 31 and the workpiece are fixed on a normal working platform. Then, the connecting bearing 24 is installed on the boring bar body 1, and two collars 21 are installed on the connecting bearing 24, ensuring that the snap-fit ​​block 25 is snapped into the snap-fit ​​groove on the collar 21. The boring bar body 1 is installed on the transmission brackets 31 on both sides, and the boring bar body 1 is inserted into the workpiece. Then, the movable push plate 32 is rotated so that the buckles 34 on both sides of the movable push plate 32 are snapped into the groove 35. At this time, the elastic fixing block 36 is snapped into the groove through its own elasticity, fixing the groove 35 and the buckle 34. Start the hydraulic telescopic rod 33. The hydraulic telescopic rod 33 pushes the movable push plate 32 to move towards the fixed push plate 22. The movable push plate 32 moves in the direction of the fixed push plate 22. When in motion, the fixed push plate 22 moves along the arc surface and cooperates with the limiting block 23 to ensure that the fixed push plate 22 unfolds along the limiting groove and fixes the boring bar body 1 inside the bearing hole, so that the fixed push plate 22 fits against the inner wall of the bearing hole. The boring bar body 1 is fixed inside the crankcase from multiple directions, thereby ensuring that the boring bar body 1 can be adapted to and installed inside the crankcase bearing holes of different diameters. Finally, the boring bar body 1 is connected to the external drive device, so that the boring bar body 1 drives the cutter head and the cutter body to process the bearing hole. When it is necessary to process bearing holes in different positions or crankcases of different lengths, the position of the connecting bearing 24 at both ends of the boring bar body 1 is adjusted to adapt to crankcases of different lengths, thereby further improving the versatility of the boring bar installation structure.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
