DETAILED DESCRIPTION
[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1 and Figure 2As shown, a fixed frame for grinding the chamfer of a gantry comprises a workbench 1, two pairs of fixed columns 12 are fixedly connected to the top of the workbench 1, and a rotating ball 13 is fixedly connected inside the fixed column 12, and a positioning plate 14 is rotatably connected to the outside of the rotating ball 13, a gantry body 11 is arranged on the top of the workbench 1, a motor 2 is fixedly connected to the top of the workbench 1, and a clamping mechanism is fixedly connected to the top of the workbench 1, and the clamping mechanism comprises a threaded rod 4 and a connecting block 5, the threaded rod 4 is fixedly connected to the output end of the motor 2, and the connecting block 5 is threadedly connected to the threaded rod 4, and both sides of the connecting block 5 are rotatably connected with rotating rods 6, the other end of the rotating rod 6 is rotatably connected with a clamping plate 7, and the door frame body 11 is arranged between the clamping plate 7 and the positioning plate 14, a pair of support plates 3 are fixedly connected to the top of the workbench 1, and the threaded rod 4 is rotatably connected to the inside of the support plate 3, and soft pads 9 are arranged on the outside of the clamping plates 7 on both sides, and sliders 8 are fixedly connected to the bottom of the clamping plates 7 on both sides, and two slide grooves 10 are opened inside the workbench 1, and the slide grooves 10 correspond to the sliders 8, and the sliders 8 are slidably connected to the inside of the slide grooves 10.
[0020] The gantry body 11 is placed between the fixed columns 12 on both sides and is placed close to the positioning plate 14. Subsequently, by starting the motor 2 on the top of the workbench 1, the start of the motor 2 causes the threaded rod 4 to start rotating. The rotation of the threaded rod 4 drives the connecting block 5 to move back and forth on it, thereby causing the rotating rods 6 on both sides to rotate back and forth. This rotation process also affects the clamping plate 7 on the other end of the rotating rod 6, causing it to move back and forth. The clamping plate 7 is limited in the slide groove 10 by the slider 8 to ensure that there is no deviation during movement. The movement of the clamping plate 7 simultaneously drives the cushion 9 to move accordingly and gradually move toward the direction of the positioning plate 14. In this process, the clamping plate 7 begins to clamp and fix the gantry body 11. Through the synergistic effect of various components, the clamping and fixing effect of different gantry frames is achieved. The design of this mechanism is intended to ensure that the gantry body 11 can be securely clamped between the fixed columns 12 on both sides through the movement of the motor 2 and the threaded rod 4, and the mutual cooperation of the clamping plate 7, the cushion 9 and other components, thereby achieving a reliable fixing effect.
[0021] like Figure 3 As shown, an electric push rod 15 is fixedly connected to the top of the workbench 1, and a fixed frame 17 is fixedly connected to the output end of the electric push rod 15. At the same time, an inner groove 16 is opened on the top of the workbench 1, and the inner groove 16 corresponds to the fixed frame 17. The fixed frame 17 is slidably connected to the inside of the inner groove 16, and an electric push rod 2 18 is fixedly connected to the top of the fixed frame 17, and the output end of the electric push rod 2 18 is fixedly connected to the outer shell 19, and a rotating column 22 is fixedly connected to the bottom of the outer shell 19. At the same time, the rotating column 22 is rotatably connected to the inside of the fixed frame 17, and a motor 20 is fixedly connected to the inside of the outer shell 19, and a grinding knife 21 is fixedly connected to the output end of the motor 20.
[0022] By starting the electric push rod 15 on the top of the workbench 1, the movement of the electric push rod 15 causes the fixed frame 17 to move left and right, and the fixed frame 17 moves within the inner groove 16. Subsequently, the motor 20 inside the shell 19 is started, and the motor drives the grinding knife 21 to start rotating. Since the chamfering angles of the gantry body 11 are different, in order to adapt to this difference, the electric push rod 28 is also started, and its movement enables the shell 19 to fine-tune the angle on the fixed frame 17 through the rotating column 22. This angle adjustment process can ensure that the grinding knife 21 maintains an appropriate distance from the chamfered part of the gantry body 11. Through such adjustment, precise grinding of the gantry body 11 with different chamfering angles can be achieved. The synergistic effect of the entire system improves the work efficiency together. The flexibility of this system design enables it to adapt to the special shapes of different gantry frames and effectively complete the chamfering grinding tasks.
[0023] It should be noted that in actual use of the device, when the staff needs to grind the chamfer of the door frame, first place the door frame body 11 between the fixed columns 12 on both sides and place it close to the positioning plate 14, and then start the motor 2 on the top of the workbench 1. When the motor 2 is started, the threaded rod 4 will be driven to rotate, and the rotation of the threaded rod 4 will drive the connecting block 5 to move back and forth on the threaded rod 4. The movement of the connecting block 5 will pull the rotating rods 6 on both sides to rotate back and forth, and at the same time, the splint 7 on the other end of the rotating rod 6 will be pulled to move, and at the same time, the splint 7 will be limited in the slide groove 10 through the slider 8 to prevent the splint 7 from deviating during movement. When the splint 7 moves, it will drive the soft pad 9 to move and gradually approach the direction of the positioning plate 14, and start The gantry body 11 is clamped and fixed, and through the cooperation between them, the effect of fixing different gantry frames is achieved. After the fixing is completed, by starting the electric push rod 15 on the top of the workbench 1, the fixed frame 17 will be driven to move left and right, and the fixed frame 17 will move within the inner groove 16. At this time, the motor 20 inside the shell 19 is started to drive the grinding knife 21 to rotate. Since the inclination angle of the chamfer of the gantry body 11 is different, the electric push rod 2 18 is started in cooperation, which will drive the shell 19 to fine-tune the angle on the fixed frame 17 through the rotating column 22, so that the distance between the grinding knife 21 and the chamfer of the gantry body 11 can be adjusted, so that the grinding knife 21 can be used for grinding. Their cooperation greatly improves the work efficiency.
