Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a cutting robot with high-precision tool adjustment function. Background Technology

[0002] The process flow for trenchless overturning and lining repair of gas pipelines is as follows: a small working pit is excavated locally, the gas pipeline is cut open, and the pipeline inspection robot is used to complete the first endoscopic inspection of the pipeline. Then, the inner wall of the gas pipeline is sprayed with water to clean the dirt inside the gas pipeline. The repair effect is inspected using a pipeline cutting robot, and the location of the branch pipe interface is located. The inner lining pipe at the branch pipe opening is cut open with the cutting tool of the pipeline cutting robot. Finally, the pipeline is welded and the working pit is backfilled. In existing technologies, pipe cutting robots require precise cutting trajectories when cutting inner lining pipes to avoid cutting off non-interface inner lining pipes. A major technical challenge is achieving accurate cutting of the inner lining pipe by remotely controlling the robot from outside. To address this issue, application number 201720667915.7 discloses a pipe cutting robot comprising a camera mechanism, a cutting mechanism, and a drive mechanism. The cutting mechanism is mounted on the drive mechanism, and the camera mechanism is mounted on the cutting mechanism. The drive mechanism moves inside the pipe, driving the cutting mechanism and camera mechanism to perform video detection and cutting of the inner lining pipe. This is a pipe cutting robot capable of automatic detection, high precision, and omnidirectional cutting. It overcomes the shortcomings of methods requiring construction personnel to enter the pipe to cut the solidified inner lining hose at pipe branch points and solves the problem of precise cutting trajectory for the cutting tool. The above-mentioned patent has the following problems when in use: In actual use, long-term use will cause the cutting tool to wear or be damaged, so the cutting tool needs to be replaced regularly. However, the existing method generally uses multiple fixing bolts to fix the cutting tool, which means that multiple fixing bolts need to be removed one by one during the maintenance of the cutting tool, which complicates the disassembly and assembly process of the cutting tool. Moreover, it requires the use of additional tools to operate, which greatly reduces the convenience of the maintenance of the cutting tool, and there is room for improvement.

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.

[0018] This utility model provides a cutting robot with high-precision tool adjustment function, referring to... Figures 1-6 A cutting robot with high-precision tool adjustment function includes a robot body 1 and a fixing mechanism 4. The robot body 1 is also equipped with a camera mechanism and an adjustment mechanism. The camera mechanism includes a camera, two LED lights, a servo motor, and a camera support frame. The camera is mounted on the servo motor, and the two LED lights are symmetrically mounted on both sides of the camera. The servo motor is mounted on the camera support frame to drive the camera and the two LED lights to rotate. The camera support frame is mounted on the cutting mechanism. In the camera module, the front cover of the camera mounting base is connected to the camera mounting base by a first hexagon socket head cap screw, and the LED light holder cover is connected to the LED light mounting base by a second hexagon socket head cap screw. The LED lights are fixed inside the LED light mounting base, and the LED light mounting base is mounted to the camera mounting base by a third hexagon socket head cap screw. On both sides of the mounting base, two LED lights are symmetrically installed on both sides of the camera. The base plate of the camera mounting base is connected to the camera mounting base through fourth internal hexagon socket head cap screws, fixing the camera inside the camera mounting base. The servo motor is connected to the base plate of the camera mounting base, realizing the indirect installation of the camera on the servo motor. The servo motor is connected to the camera support frame. The servo motor can drive the camera mounting base to rotate, specifically controlling the rotation to 270°, thereby achieving the effect of precise adjustment of the cutting trajectory. Through the action of the adjustment mechanism, the angle and position of the cutting tool 33 can be appropriately adjusted. The specific structure and working principle of the robot body 1, camera mechanism and adjustment mechanism can be referred to the literature with application number: 201720667915.7, which is the prior art and will not be described in detail here. A cutting motor 2 is installed on the robot body 1. The output end of the cutting motor 2 is fixedly connected to a mounting base 6. A cutting tool 3 is slidably mounted on the mounting base 6. A fixing mechanism 4 for limiting the cutting tool is provided on the mounting base 6. The fixing mechanism 4 includes a rotating shaft 41, a locking block 42, a gear 43, a sleeve 44, a transmission plate 45, and a rack 46. Two rotating shafts 41 are rotatably connected to the mounting base 6, and a locking block 42 is fixedly connected to each of the two rotating shafts 41. Both locking blocks 42 are engaged with the cutting tool 3. A sleeve 44 is slidably fitted on the mounting base 6, and two racks 46 are installed on the sleeve 44. Through the cooperative design between the mounting base 6, the cutting tool 3, the connecting block 5, the rotating shaft 41, the locking block 42, and the sleeve 44, the cutting tool 3 can be quickly disassembled and assembled without the aid of tools, greatly improving convenience and efficiency.

[0019] In this configuration, each of the two racks 46 is also connected to a gear 43, and the two gears 43 are fixedly connected to one end of each of the two rotating shafts 41 to drive the two rotating shafts 41.

[0020] In this configuration, a transmission plate 45 is fixedly connected to one side of each of the two racks 46, and both transmission plates 45 are fixedly connected to the sleeve 44 for transmission, which allows the sleeve 44 to drive the two racks 46 to move synchronously on the mounting base 6.

[0021] In this method, two connecting blocks 5 are fixedly connected to the cutting tool 3, and two locking blocks 42 are respectively locked to the two connecting blocks 5. Through the interaction between the two connecting blocks 5 and the mounting base 6, the output end of the cutting motor 2 can drive the cutting tool 3 to rotate through the mounting base 6, thereby achieving the cutting effect.

[0022] In this method, a slot 7 is provided on one side of each of the two connecting blocks 5. The two slots 7 are adapted to the two locking blocks 42. Through the interaction between the two locking blocks 42 and the two slots 7, the two connecting blocks 5 can be limited and fixed.

[0023] In this method, the mounting base 6 has two mounting slots, and the two connecting blocks 5 are adapted to the two mounting slots. The two mounting slots correspond to the two locking blocks 42 respectively, which facilitates the installation of the cutting tool 3 on the mounting base 6.

[0024] In this method, two grooves are provided on the sleeve 44, and the two grooves correspond to two mounting slots, which facilitates the movement of the sleeve 44 on the mounting base 6.

[0025] In this method, a limiting screw 8 is installed on the mounting base 6. The limiting screw 8 is in contact with the sleeve 44 and is used to limit the sleeve 44.

[0026] Working principle: When maintenance is required on the cutting tool 3, firstly, the operator manually rotates the limit screw 8 to disengage it from the mounting base 6, thereby releasing the limitation on the sleeve 44. Then, by pulling the handle at one end of the sleeve 44, the sleeve 44 slides a certain distance on the mounting base 6. At the same time, the sleeve 44 drives the rack 46 to move synchronously on the mounting base 6 through the transmission plate 45. Simultaneously, the rack 46 meshes with the gear 43, causing the gear 43 to drive the locking block 42 to rotate a certain angle through the rotating shaft 41, and causing the locking block 42 to disengage from the slot 7 on the connecting block 5, thereby releasing the limitation on the connecting block 5. Afterwards, by removing the cutting tool 3 from the mounting base 6, the cutting tool 3 can be quickly disassembled. Conversely, this allows for the rapid installation of the cutting tool 3.

[0027] The technological advancement of this invention compared to the prior art is that the cutting tool 3 can be quickly assembled and disassembled without the aid of tools through the cooperation of various components, which improves convenience and efficiency. Moreover, the structure is simple and more practical.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
