Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shield machine cutter head processing, and particularly relates to a cutting tool for the cutter box holes on the cutter head side block. Background Technology
[0002] Holes need to be cut on the shield machine cutter head for welding the cutter box. However, during cutting, only the cutting range is determined by scribing, and there is no need to precisely cut out the adapted holes. If the hole size is too large, the weld seam will be too wide during welding, increasing the welding difficulty; if the hole size is too small, the cutter box cannot be fully embedded and secondary cutting is required, affecting the work progress. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a cutting tool for the cutter box holes on the cutter head side block, which can precisely cut out the cutter box holes adapted for welding on the cutter head, facilitating the welding operation of workers and effectively solving the problems in the background technology.
[0004] To achieve the above purpose, the utility model provides the following technical scheme: A cutting tool for the cutter box holes on the cutter head side block includes a base and a support plate. The support plate is arranged directly above the base. Both the support plate and the base are square frames with hollow interiors. The base and the support plate are connected by a support rod. An annular groove is arranged on the inner side surface of the support plate, and the annular groove is adapted to the welding track of the cutter box. A traveling mechanism is arranged in the annular groove, and the traveling mechanism is connected to a cutting torch for controlling the cutting torch to travel along the outside of the cutter box for one week for welding.
[0005] As a preferred technical scheme of the utility model, an annular protrusion is arranged in the annular groove, and the annular protrusion divides the inside of the annular groove into two traveling tracks. The traveling mechanism includes traveling wheels and a connecting shaft. The number of traveling wheels is two, and the two traveling wheels are respectively located in the two traveling tracks. The connecting shaft is used to connect the two traveling wheels.
[0006] As a preferred technical scheme of the utility model, a connecting plate is arranged on the outer side surface of the connecting shaft, and a positioning cylinder for the head of the cutting torch to pass through is arranged on the connecting plate.
[0007] As a preferred technical scheme of the utility model, external threads are arranged at both the upper and lower ends of the outer side surface of the positioning cylinder, and a connecting nut is threadedly connected to the outer side surface of the external thread. The connecting nut is used to connect the positioning cylinder and the cutting torch.
[0008] As a preferred technical scheme of the utility model, the connecting plate and the positioning cylinder are connected by welding.
[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: The cutting tooling for the knife box holes on the edge block of the cutter head is reasonably designed and convenient to operate. By setting a frame-shaped support plate and arranging an annular groove on the inner side of the support plate, the size of the annular groove is adapted to the size of the knife box hole. The walking wheels move along the annular groove, thereby driving the head of the cutting gun to move for cutting, so as to ensure the accurate size of the knife box holes cut on the cutter head, facilitate the embedding and welding of the knife box, and improve the work quality and efficiency.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments (for the convenience of description and understanding, the upper part is described as the upper part below). Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Figure 2
[0015] Figures 1-3 Please refer to a technical solution provided by the present utility model: A cutting tooling for the knife box holes on the edge block of the cutter head includes a base 3 and a support plate 1. The support plate 1 is arranged directly above the base 3. Both the support plate 1 and the base 3 are square frames with hollow interiors, and the size of the square frames is slightly larger than the size of the knife box holes to be cut. The support plate 1 and the base 3 are connected by support rods 4. An annular groove 2 is arranged on the inner side surface of the support plate 1, and the annular groove 2 is adapted to the welding track of the knife box. Both the base 3 and the support plate 1 are made of iron and have a large weight, so it is difficult to move under external force after being placed on the cutter head. A walking mechanism is arranged in the annular groove 2, and the walking mechanism is connected to the cutting gun for controlling the cutting gun to weld along the outer circumference of the knife box for one week. When cutting, the worker only needs to control the cutting gun to move around the annular groove 2 for one week, avoiding the situation of cutting position deviation and improving the cutting position accuracy of the knife box holes.
[0016] Furthermore, in order to ensure the stable walking of the walking mechanism, an annular protrusion 10 is provided in the annular groove 2, and the annular protrusion 10 divides the annular groove into two walking tracks. The walking mechanism includes walking wheels 11 and a connecting shaft 9. The number of walking wheels 11 is two, and the two walking wheels 11 are respectively located in the two walking tracks. The connecting shaft 9 is used to connect the two walking wheels 11.
[0017] Furthermore, in order to facilitate the position limitation of the cutting gun head, a connecting plate 5 is provided on the outer side of the connecting shaft 9. The connecting plate 5 is connected to the positioning tube 6 by welding. The connecting plate 5 is provided with a positioning tube 6 for the cutting gun head to pass through.
[0018] Furthermore, in order to facilitate the fixation of the cutting gun head, external threads 8 are provided at both upper and lower ends of the outer side surface of the positioning tube 6, and the outer side surface of the external thread 8 is threadedly connected with a connecting nut 7. After the cutting gun head passes through the positioning tube 6, the connecting nut 7 is rotated so that the connecting nut 7 is threaded on the corresponding positions of the threads of the positioning tube 6 and the cutting gun, thereby fixing the cutting gun.
[0019] When in use: place the tool at the cutting position on the cutter disc, pass the head of the cutting gun through the positioning tube 6, and by rotating the connecting nuts 7 on both sides of the positioning tube 6, partially thread the connecting nuts 7 into the corresponding threaded connection of the cutting gun head to complete the fixing of the cutting gun. When cutting, the worker only needs to move the cutting gun along the annular groove.
[0020] The utility model can realize the positioning of the cutting position of the knife box hole on the knife disc, ensure that the cutting gun completes the circular cutting along the set trajectory, avoid the deviation of the knife box hole position after cutting, greatly reduce the number of rework times, and improve work efficiency.
