Description

Technical Field

[0001] The utility model relates to the technical field of cultural relics processing, in particular to a bead turning dust collecting protective cover. Background Art

[0002] Bead products in collectibles and ornaments are mostly processed by woodworking lathes in the prior art, but the existing woodworking lathes have the following shortcomings during processing: 1. Since the materials to be processed are mostly wood, during the circle cutting process, the material itself rotates and contacts the tool for surface cutting. During the cutting process, the dust generated is easy to fly in the circumferential direction of the material rotation, polluting the working environment, and it will also adhere to the surfaces of processing tools, guide rails, rotating shafts and other structures. When used for a long time, it will not only affect the observation of material processing, but the dust accumulated on the guide rails and rotating shafts will also have an adverse effect on the processing accuracy of the equipment; 2. During the material cutting process, if "bad particles" appear, that is, the material has internal defects due to insect bites, growth defects and other problems, the material is prone to breakage and splashing during the process of rotation and contact with the tool. If the splashed broken material comes into contact with the operator's skin, it is very easy to scratch the skin. Utility Model Content

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0027] See also Figure 1-Figure 8 As shown, the utility model provides a bead turning dust collection protective cover, comprising a tool cover 1, a fixing plate 2 and a tool holder 3, wherein the fixing plate 2 is mounted on the tool holder 3, the tool cover 1 is fixedly connected to the fixing plate 2, and the tool cover 1 is an integrally formed plastic cover; a front bead turning knife 4 is arranged on the tool holder 3, and after the fixing plate 2 is fixedly matched with the tool holder 3, the front bead turning knife 4 is pressed;

[0028] The tool cover 1 includes a main cover body 12, which is a hollow structure. A dust suction pipe 16 is provided on the main cover body 12. The dust suction pipe 16 is connected to a negative pressure dust suction device to generate negative pressure inside the main cover body 12, thereby absorbing dust generated during the material cutting process. The dust suction pipe 16 is communicated with the interior of the main cover body 12. A fixing frame 14 is provided on the main cover body 12 to cooperate with the fixing plate 2 for fixing. The fixing frame 14 is connected to the fixing plate 2 by screws. A tool hole 15 is provided on the upper part of the main cover body 12, and an axial groove 17 opening downward is provided on the lower part of the main cover body 12. After the front bead turning knife 4 is inserted into the interior of the tool cover 1 from the tool hole 15, its lower end enters the axial groove 17. When in use, the gantry moving structure of the bead turning machine moves the front bead turning knife 4 to one side of the unprocessed material by moving the knife seat 3, and moves the front bead turning knife 4 to one side of the unprocessed material through the CNC program. The front bead cutting tool 4 is driven to cut the surface of the material. During the cutting process, the generated dust enters the main cover body 12 through the shaft groove 17, and finally enters the negative pressure dust collection device through the dust collection pipe 16; the shaft groove 17 passes through the lower part of the main cover body 12 in the horizontal direction, and forms a straight strip opening on the bottom surface of the main cover body 12; the shaft groove 17 is a vacant space matching the material driving shaft, and the material driving shaft can be inserted into the shaft groove 17, so that the material cooperates with the front bead cutting tool 4 inside the shaft groove 17 to complete the cutting of the material surface; the top of the shaft groove 17 is a concave arc-shaped top. After the arc-shaped top is set, the opening size of the end of the shaft groove 17 can be reduced while satisfying the rotation of the material driving shaft, which is conducive to concentrating the wind force of dust collection and improving the dust collection efficiency and cleanliness; the width of the shaft groove 17 is not more than half of the thickness of the main cover body 12 to ensure the structural strength of the main cover body 12 corresponding to the shaft groove 17;

[0029] The fixing frame 14 is provided with a fixing groove 13, and at least two holes for mounting screws are provided inside the fixing groove 13. If the screws connecting the fixing frame 14 and the fixing plate 2 are exposed on the surface of the fixing frame 14, since the fixing frame 14 is located at the front of the entire device, there is a certain risk of accidental touch and scratching. However, by setting the holes inside the fixing groove 13, the fixing screws can be hidden, thereby improving the safety of the device. After the fixing frame 14 is connected to the fixing plate 2, the top surface of the main cover body 12 is attached to the bottom surface of the knife seat 3 and the knife hole 15 is closed. After such arrangement, the top surface of the main cover body 12 is attached to the bottom surface of the knife seat 3, and the knife hole 15 is closed, so that only the shaft groove 17 is left at the air inlet of the main cover body 12, which is conducive to maintaining the wind pressure of dust collection and improving the dust adsorption efficiency.

[0030] The main cover body 12 is provided with an observation hole 11 , which corresponds to the position of the shaft groove 17 . The observation hole 11 can be used to observe the position of the blade of the front bead cutter 4 and the processing status of the material. The observation hole 11 is arranged on the front side of the main cover body 12 .

[0031] By adopting the above structure, after the vacuum tube 16 is connected to an external negative pressure vacuum device, negative pressure can be formed inside the main cover body 12. Therefore, in the process of the front bead cutting tool 4 cutting the material, the dust generated by the cutting is adsorbed into the main cover body 12 in real time through the shaft groove 17, and enters the negative pressure vacuum device through the vacuum tube 16 and the negative pressure tube of the negative pressure device, thereby completing the dust collection, eliminating the space environment pollution and equipment surface dirt caused by dust escape, extending the maintenance time of the equipment, and improving the environmental quality of the work site; during the processing, the front bead cutting tool 4 and the material are both located inside the shaft groove 17. If the material is broken and separated from the fixture during the rotary cutting process, it will not fly out under the cover of the tool cover 1, and the safety is better.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
