Description

Technical Field

[0001] This utility model relates to the technical field of boring machine guide rail protective covers, and in particular to an installation structure for boring machine guide rail protective covers. Background Technology

[0002] The guide rail protective cover is an indispensable and crucial component during the operation of a boring machine. Its primary function is to protect the guide rails from external damage. To avoid hindering machine movement, most boring machine guide rail protective covers currently employ a bellows-style design. This type of cover offers excellent telescopic performance and is equipped with flange plates at both ends. One flange plate is fixedly connected to the boring machine, while the other flange plate is connected to the slide. As the slide slides along the guide rail, the protective cover can flexibly extend and retract under the influence of the flange plates, thus providing comprehensive protection for the guide rail. However, the flange plates are often fixed using bolt connections, which require tools for assembly and disassembly, making them quite cumbersome.

[0003] A search revealed Chinese Patent Publication No. CN216882692U, which discloses a guide rail protective cover. This utility model relates to a guide rail protective cover comprising two flange plates, with multiple reinforcing plates evenly distributed between the two flange plates. A telescopic fabric is disposed between adjacent reinforcing plates, and telescopic components are provided at the bottom of each reinforcing plate. The telescopic ends of the telescopic components are slidably connected to the grooves of the guide rail. This utility model, by providing telescopic components at the bottom of the reinforcing plates, allows the distance between the telescopic ends of the telescopic components and the grooves of the guide rail to be adjusted during installation, enabling the guide rail protective cover to adapt to guide rails of different widths.

[0004] For example, the two flange plates used in the protective cover of the aforementioned patent require bolts to fix them to the machine tool and guide rail during actual installation. While this bolted connection method provides a certain degree of fixation and ensures the stability of the protective cover during operation, it has significant drawbacks in practical operation. When the protective cover needs to be disassembled for maintenance or repair of the guide rail, multiple bolts must be frequently removed and reassembled. This process is not only cumbersome but also time-consuming, greatly reducing maintenance efficiency. Therefore, this paper proposes an installation structure for a boring machine guide rail protective cover to solve the above problems. Utility Model Content

[0018] 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.

[0019] Reference Figure 1 - Figure 3This utility model provides an embodiment of an installation structure for a boring machine guide rail protective cover, including a bellows cover 1. Both ends of the bellows cover 1 are fixedly connected to a clamping plate 2. A mounting plate 3 is clamped to the side of the clamping plate 2 away from the bellows cover 1. A mounting ear 4 is fixedly connected to the outer wall of the mounting plate 3. The mounting ear 4 is a hollow protrusion-shaped structure. In use, firstly, the bolt is passed through the hole in the middle of the mounting ear 4. Then, the mounting plate 3 on the left side of the bellows cover 1 is locked onto the boring machine using the bolt and the mounting ear 4. Then, the mounting plate 3 on the right side of the bellows cover 1 is locked onto the slide using the bolt and the mounting ear 4. A disassembly and assembly mechanism 5 is provided between the clamping plate 2 and the mounting plate 3. An auxiliary mechanism 6 is provided on the inner wall of the mounting plate 3.

[0020] Reference Figure 2 - Figure 4 The disassembly and assembly mechanism 5 includes a positioning rod 51, which is rotatably connected to the inner wall of the clamping plate 2. The positioning rod 51 allows the clamping plate 2 and the mounting plate 3 to be quickly joined together. A steel ball 52 is fixedly connected to the inner wall of the positioning rod 51. A rotating plate 53 is fixedly connected to the end of the positioning rod 51 away from the mounting plate 3. The rotating plate 53 allows the positioning rod 51 to be rotated and the torsion spring 54 to be compressed. A torsion spring 54 is provided at the connection between the positioning rod 51 and the clamping plate 2. One end of the torsion spring 54 is rotatably connected to the inner wall of the rotating plate 53, and the other end is fixedly connected to the outer wall of the clamping plate 2. Under the elastic action of the torsion spring 54, the positioning rod 51 can be rotated and reset. A through hole 55 is provided on the side of the mounting plate 3 closest to the clamping plate 2. The positioning rod 51 is inserted into the inner wall of the through hole 55. A limiting hole 5, coaxial with the through hole 55, is provided on the inner wall of the mounting plate 3. 6. The outer wall of the steel ball 52 is attached to the inner wall of the limiting hole 56. The steel ball 52, in conjunction with the limiting hole 56, can limit the positioning rod 51, thereby fixing the positioning rod 51 inside the through hole 55. The inner wall of the through hole 55 is provided with a spiral groove 57, which can guide the steel ball 52. During the insertion of the positioning rod 51 into the through hole 55, the steel ball 52 can drive the positioning rod 51 to rotate. The spiral groove 57 is a spiral groove structure with two openings, and the two openings of the spiral groove 57 are staggered. One opening of the spiral groove 57 is connected to the inside of the limiting hole 56, and the other opening of the spiral groove 57 is connected to the outside. When the torsion spring 54 drives the positioning rod 51 to rotate and reset, the steel ball 52 will be aligned with the external opening. Therefore, the steel ball 52 will be staggered with the opening near the limiting hole 56.

[0021] Reference Figure 1 - Figure 3The auxiliary mechanism 6 includes a push plate 61, which is slidably connected to the inner wall of the limiting hole 56. The push plate 61, in conjunction with the turntable 63, can push the positioning rod 51, causing the positioning rod 51 to move out of the limiting hole 56. The push plate 61 is a hollow annular plate structure. A spring 62 is fixedly connected to the side of the push plate 61 away from the positioning rod 51. The end of the spring 62 away from the push plate 61 is fixedly connected to the inner wall of the limiting hole 56. The elasticity of the spring 62 can push the push plate 61, causing the push plate 61 to slide and reset within the inner wall of the limiting hole 56. The inner wall of the push plate 61 is rotatably connected to the turntable 63. The side of the turntable 63 closest to the positioning rod 51 is in contact with the end of the positioning rod 51. The rotation of the turntable 63 ensures that the positioning rod 51 is not disturbed during the rotation and reset process.

[0022] Working principle: When in use, first pass the bolt through the hole in the middle of the mounting ear 4, then use the bolt to lock the mounting plate 3 on the left side of the bellows cover 1 onto the boring machine with the mounting ear 4, and then use the bolt to lock the mounting plate 3 on the right side of the bellows cover 1 onto the slide table with the mounting ear 4, so that the bellows cover 1 covers the guide rail. At this time, the bellows cover 1 can protect the guide rail.

[0023] When the bellows cover 1 needs to be disassembled for maintenance of the guide rail, firstly, rotate the positioning rod 51 by rotating the plate 53. At this time, the positioning rod 51 will rotate on the inner wall of the clamping plate 2. Simultaneously, the rotating plate 53 will compress the torsion spring 54. While rotating, the positioning rod 51 will drive the steel ball 52 to move synchronously. When the steel ball 52 moves to the opening of the spiral groove 57, it can push the clamping plate 2, causing the clamping plate 2 to separate from the mounting plate 3. At the same time, the clamping plate 2 will drive the positioning rod 51 to move synchronously. At this time, the positioning rod 51 will drive the steel ball 52 to slide into the spiral groove 57 from one side of the opening and slide out of the spiral groove 57 from the other side of the opening. After the clamping plate 2 separates from the mounting plate 3, the bellows cover 1 can be removed from the guide rail for maintenance and repair.

[0024] After the maintenance work is completed, when the bellows cover 1 needs to be installed on the guide rail, the positioning rod 51 is inserted into the through hole 55, so that the clamping plate 2 and the mounting plate 3 are aligned. At the same time, during the insertion of the positioning rod 51 into the through hole 55, it will drive the steel ball 52 to enter the spiral groove 57 through the opening on one side of the spiral groove 57. At this time, under the guidance of the spiral groove 57, the steel ball 52 will push the positioning rod 51 during the insertion into the through hole 55, so that the positioning rod 51 rotates on the inner wall of the clamping plate 2. While the positioning rod 51 is rotating, it will drive the rotating plate 53 to swing and compress the torsion spring 54. As the positioning rod 51 is continuously inserted, it will cause the steel ball 52 to move out of the spiral groove 57 from the opening at the other end of the spiral groove 57, causing the steel ball 52 to disengage from the guide of the spiral groove 57. At this time, under the elastic action of the torsion spring 54, the positioning rod 51 will rotate and reset. After the positioning rod 51 rotates and resets, it will cause the steel ball 52 to be misaligned with the opening of the spiral groove 57 near the limiting hole 56. At this time, the steel ball 52 can be used in conjunction with the limiting hole 56 to limit the positioning rod 51, thereby fixing the positioning rod 51 inside the through hole 55. Then, the clamping plate 2 and the mounting plate 3 can be connected together to complete the installation of the bellows cover 1.

[0025] When the positioning rod 51 is inserted into the limiting hole 56 through the through hole 55, the positioning rod 51 will push the turntable 63, causing the turntable 63 to push the push plate 61. At this time, the push plate 61 will slide on the inner wall of the limiting hole 56 and compress the spring 62. When it is necessary to disassemble the clamping plate 2 and the mounting plate 3, the positioning rod 51 is rotated by the turntable 53, causing the positioning rod 51 to move the steel ball 52 to the opening of the spiral groove 57. At this time, the limiting hole 56 will release the limiting of the steel ball 52, and the compressed return spring 62 will push the push plate 61, causing the push plate 61 to drive the turntable 63 to push the positioning rod 51, so that the positioning rod 51 will drive the steel ball 52 to slide from the opening of the spiral groove 57 into the interior of the spiral groove 57. This allows the steel ball 52 to quickly enter the interior of the spiral groove 57, improving the ease of disassembly of the clamping plate 2 and the mounting plate 3.

[0026] 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.
