Description

Technical Field

[0001] The invention relates to the technical field of coupling production, in particular to a boring device for producing ship couplings. Background Art

[0002] The ship coupling is a very important component in the ship power system. It is mainly used to connect the two shafts in the ship propulsion shaft system, such as connecting the engine output shaft and the propeller shaft. Its main function is to transfer power from the engine to the propeller, while allowing a certain relative displacement and angular deviation between the shafts to compensate for the axial, radial and angular changes caused by various factors (such as hull deformation, installation errors, temperature changes, etc.) during the operation of the shaft system; when the ship coupling is produced, the holes on the coupling parts are precisely bored by a boring device to meet the high-precision requirements of the coupling during assembly and use.

[0003] The existing boring device will generate a large amount of debris during the boring operation, and these debris will splash around the surrounding environment. This situation will bring safety hazards to the operators. In order to ensure their own safety, most operators wear corresponding protective gear for protection. However, in actual operation, for example, goggles may be scratched by the impact of splashing debris, affecting the operator's line of sight, thereby interfering with the normal operation process and reducing the service life of the goggles; in addition, the splashing of debris will also have a serious impact on the working environment, not only polluting the working area, making the ground slippery and messy, but also increasing the workload of cleaning. In view of this, we propose a boring device for the production of ship couplings. Summary of the invention

[0006] As a further improvement of the technical solution, the limiting mechanism comprises at least two hydraulic rods fixedly mounted on a fixed plate, and the output ends of the two hydraulic rods are fixedly connected to clamping rods.

DETAILED DESCRIPTION

[0018] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 8 As shown, this embodiment provides a boring device for producing ship couplings, including a body 100, a boring head 110 is rotatably connected to one side of the body 100, a driving motor is fixedly installed on one side of the body 100, and the driving motor is started to drive the boring head 110 to rotate to bore the workpiece, a mounting plate 120 is provided on one side of the body 100, a fixing plate 121 is fixedly connected to the mounting plate 120, a limiting mechanism 200 for elastically clamping the workpiece is provided on one side of the fixing plate 121, and a protective mechanism 300 is provided on the limiting mechanism 200. When the limiting mechanism 200 elastically clamps the workpiece, the protective mechanism 300 is driven to rotate to be perpendicular to the limiting mechanism 200 to cover the boring area, so as to prevent the generated chips from splashing out and injuring the operator; When the limiting mechanism 200 does not clamp the workpiece, it drives the protection mechanism 300 to rotate parallel to the limiting mechanism 200, maintains the protection mechanism 300, and self-cleans the inner wall of the protection mechanism 300 when it rotates, reducing the workload of subsequent cleaning of the protection mechanism 300.

[0020] The present invention takes into account that the existing boring device will generate a large amount of debris during the boring operation, and these debris will splash around the surrounding environment, which will bring potential safety hazards to the operator. Although most operators wear corresponding protective gear for protection, in actual operation, for example, goggles may be scratched by the impact of the splashing debris, affecting the operator's vision; therefore, the protection mechanism 300 is set to rotate from a state parallel to the fixed plate 121 to a state perpendicular to the fixed plate 121 when the workpiece is processed. When the protection mechanism 300 is in a vertical state, the boring area can be shielded, effectively preventing the chips generated during the boring process from splashing out and injuring the operator; when the protection mechanism 300 is in a horizontal state, the operator can more conveniently approach the inner wall of the protection mechanism 300 to clean it, check the wear or perform maintenance work; Considering that when a rigid material such as a clamping jaw clamps a workpiece, the surface of the workpiece may be damaged. Therefore, a limit mechanism 200 is provided. The limit mechanism 200 can be elastically moved to adjust the position according to the convex surface of the workpiece, so as to better fit the surface of the workpiece to be processed, realize effective clamping, and avoid damage to the workpiece caused by hard contact. The limit mechanism 200 also plays a buffering role to further reduce the damage to the workpiece. In addition, the flying debris will have a serious impact on the working environment. It will not only pollute the working area, make the ground slippery and messy, but also increase the workload of cleaning. Therefore, a limiting mechanism 200 and a protective mechanism 300 are set. When the limiting mechanism 200 clamps the workpiece, it drives the protective mechanism 300 to move while driving the cleaning component of the protective mechanism 300 to move elastically, so as to self-clean the inner wall of the protective mechanism 300, and scrape the debris adhering to the protective mechanism 300 onto the mounting plate 120, so as to facilitate the subsequent centralized processing of the debris, avoid the accumulation of debris on the protective mechanism 300, reduce the visibility of the protective mechanism 300, and reduce the workload of the subsequent cleaning of the protective mechanism 300.

[0021] Considering the need to clamp and limit the workpiece, such as Figure 3-Figure 5 As shown, the specific structure of the limiting mechanism 200 is further disclosed. The limiting mechanism 200 includes at least two hydraulic rods 210 fixedly mounted on the fixed plate 121. The output ends of the two hydraulic rods 210 are fixedly connected with clamping rods 211. When the hydraulic rods 210 are started, the clamping rods 211 are driven to move to limit the workpiece.

[0022] When the limiting mechanism 200 clamps the workpiece, it can better fit the surface of the workpiece, such as Figure 6 As shown, a plurality of grooves are provided on the adjacent sides of the two clamping rods 211, and suction cups 212 are slidably connected in the grooves. A No. 3 return spring 213 is fixedly connected to the side of the suction cup 212 located in the groove, and the side of the No. 3 return spring 213 away from the suction cup 212 is fixedly connected to the inner wall of the adjacent groove. The movement of the clamping rod 211 drives the suction cup 212 to move and clamp the workpiece to limit the position. When the suction cup 212 moves, it cooperates with the elastic movement of the No. 3 return spring 213. Even if the surface of the workpiece is not completely flat, the suction cup 212 can also adjust its position through the expansion and contraction of the No. 3 return spring 213 to better fit the surface of the workpiece to be processed, thereby further improving the clamping effect. When the suction cup 212 clamps the workpiece, the No. 3 return spring 213 also plays a buffering role to reduce damage to the workpiece.

[0023] When boring a workpiece, a lot of debris will be generated. In order to shield the debris, such as Figure 4-Figure 6As shown, the specific structure of the protection mechanism 300 is further disclosed. The protection mechanism 300 at least includes a rotating rod 310 rotatably connected to the two clamping rods 211. The outer wall of the rotating rod 310 is fixedly connected with a protection plate 311. The protection plate 311 is made of transparent material to facilitate the operator to observe the progress of boring the workpiece. The bottom of the two protection plates 311 is fixedly connected with a disk 320. The disk 320 is fixedly connected with a limiting rod 321. The limiting rod 321 rotates 90 degrees to drive the disk 320 to rotate, thereby driving the rotating rod 310 to rotate, and then driving the protection plate 311 to rotate 90 degrees, so as to shield the boring area, and effectively prevent the chips generated during the boring process from splashing out and injuring the operator.

[0024] In order to drive the protection plate 311 to rotate, Figure 5 and Figure 7-Figure 8 As shown, a sliding groove is provided on one side of the fixing plate 121 near the rotating rod 310, and two sliders 130 are slidably connected in the sliding groove. A second telescopic rod 131 is fixedly connected to one side of the slider 130, and a positioning rod 132 is fixedly connected to the output end of the two second telescopic rods 131, and the two positioning rods 132 are respectively slidably connected to the adjacent limiting rods 321. The outer walls of the two second telescopic rods 131 are sleeved with a second return spring 133. When the positioning rod 132 is squeezed away from the slider 13 0 moves to one side, at this time, the No. 2 telescopic rod 131 is stretched, and the No. 2 return spring 133 is deformed by the force, as shown by arrow a, when the positioning rod 132 moves, under the limitation of the length of the limit rod 321, as shown by arrow b, the limit rod 321, the disk 320, the protective plate 311 and the movable plate 312 are driven to rotate, and when the positioning rod 132 is no longer squeezed, the No. 2 return spring 133 restores the deformation force and drives the No. 2 telescopic rod 131 and the positioning rod 132 to reset and move.

[0025] In order to drive the positioning rod 132 to move, Figure 4-Figure 5 and Figure 7-Figure 8 As shown, two extrusion blocks 140 are fixedly connected to one side of the fixed plate 121 close to the positioning rod 132, and the extrusion block 140 is parallel to the positioning rod 132. When the hydraulic rod 210 drives the clamping rod 211 to move, the protective plate 311 is driven to move, and then the disc 320 is driven to move. The movement of the disc 320 drives the limit rod 321 to move, so that the limit rod 321 pulls the positioning rod 132 to move, thereby driving the slider 130 and the second telescopic rod 131 to move. Figure 7 As shown, during the movement of the positioning rod 132, it is squeezed by the squeezing block 140, as shown by arrow a, driving the positioning rod 132 to move.

[0026] In order to clean the debris adhering to the inner wall of the clamping rod 211, as Figure 4As shown, the bottom of the two protective plates 311 are slidably connected to a connecting rod 330, and the connecting rod 330 is fixedly connected to a scraper rod 331, and the scraper rod 331 fits the inner wall of the protective plate 311, and one side of the two connecting rods 330 is fixedly connected to a No. 5 return spring 332, and the side of the No. 5 return spring 332 away from the connecting rod 330 is fixedly connected to the inner wall of the adjacent protective plate 311. When the protective plate 311 is parallel to the extrusion block 140, the connecting rod 330 is parallel to the extrusion block 140. When the protective plate 311 is parallel to the fixed plate 121, the spacing value between the connecting rod 330 and the workpiece is less than At this time, the spacing value between the positioning rod 132 and the workpiece is large, so when the protective plate 311 moves, the connecting rod 330 is first squeezed with the extrusion block 140, thereby driving the connecting rod 330 to move, and then driving the scraper rod 331 to move, which can scrape off the debris adhering to the scraper rod 331, so as to facilitate the subsequent centralized processing of the debris. At this time, the No. 5 return spring 332 is deformed under the force. When the subsequent protective plate 311 rotates to a parallel state with the fixed plate 121, the No. 5 return spring 332 restores the deformation force and drives the connecting rod 330 and the scraper rod 331 to reset and move, so that the inner wall of the protective plate 311 can be scraped for the second time.

[0027] Considering that the clamping rod 211 clamps workpieces of different diameters, in order to better shield the top, such as Figure 5 As shown, the two protective plates 311 are both slidably connected with a moving plate 312, and one side of the moving plate 312 located inside the protective plate 311 is fixedly connected with a No. 4 return spring 313, and the side of the two No. 4 return springs 313 away from the moving plate 312 is fixedly connected to the inner wall of the adjacent protective plate 311. The No. 4 return spring 313 drives the moving plate 312 to move elastically, so that the moving plate 312 can automatically adjust its shielding range, thereby improving the protective effect of the protective mechanism 300.

[0028] In order to further improve the protection effect of the protection mechanism 300, as Figure 1 As shown, two No. 1 telescopic rods 111 are fixedly connected to one side of the machine body 100 close to the boring head 110, and a baffle 112 is fixedly connected to the output ends of the two No. 1 telescopic rods 111, and the baffle 112 is slidably connected to the boring head 110. The outer walls of the two No. 1 telescopic rods 111 are sleeved with No. 1 return springs 113. When the transmission device of the machine body 100 drives the boring head 110 to move and adjust the boring position, it drives the No. 1 telescopic rod 111 to move, thereby driving the baffle 112 to move, and one side of the protective plate 311 can be enclosed. The baffle 112 is made of transparent material, which is convenient for the operator to penetrate the boring progress, and through the elastic force of the No. 1 return spring 113, the baffle 112 is driven to move according to the moving distance of the boring head 110.

[0029] Working principle: By starting the hydraulic rod 210, the clamping rod 211 is driven to move, thereby driving the suction cup 212 to move to clamp and limit the workpiece. When the suction cup 212 moves, it moves elastically with the No. 3 return spring 213. Even if the surface of the workpiece is not completely flat, the suction cup 212 can adjust its position through the expansion and contraction of the No. 3 return spring 213 to better fit the surface of the workpiece to achieve effective clamping. When the clamping rod 211 moves, the rotating rod 310 is driven to move, thereby driving the protective plate 311 to move, and then driving the disc 320 to move. The movement of the disc 320 drives the limiting rod 321 to move, so that the limiting rod 321 pulls the positioning rod 132 to move, thereby driving the slider 130 and the second telescopic rod 131 to move. During the movement of the positioning rod 132, it is squeezed by the squeezing block 140, driving the positioning rod 132 to move to the side away from the slider 130. At this time, the second telescopic rod 131 is stretched. When the positioning rod 132 moves, under the limitation of the length of the limiting rod 321, the limiting rod 321 is driven to rotate 90 degrees, thereby driving the disc 320, the rotating rod 310 and the protective plate 311 to rotate 90 degrees, shielding the boring area, and effectively preventing the chips generated during the boring process from splashing out and injuring the operator; During the movement of the protective plate 311, the connecting rod 330 is driven to move. Since when the protective plate 311 is parallel to the positioning rod 132, the spacing value between the connecting rod 330 and the workpiece is smaller than the spacing value between the positioning rod 132 and the workpiece at this time, when the protective plate 311 moves, the connecting rod 330 is first squeezed with the extrusion block 140, thereby driving the connecting rod 330 to move, and then driving the scraper rod 331 to move, which can scrape off the debris adhering to the protective plate 311, facilitating the subsequent centralized processing of the debris.
