Description

Technical Field

[0001] This utility model belongs to the field of surface milling cutter technology, and specifically relates to a surface milling cutter structure. Background Technology

[0002] Surface milling cutters are a type of tool used to mill complex curved surfaces according to a predetermined shape. They mainly consist of two parts: the cutter body and the cutting teeth. The cutter body and the cutting teeth are fixedly connected, and the cutting teeth perform milling on the workpiece by driving the cutter body to rotate.

[0003] As is well known, the cutting teeth of surface milling cutters experience significant wear. In practical applications, it is necessary to periodically repair the cutting teeth of surface milling cutters. However, most common surface milling cutters in existing technologies are integrated units. Therefore, when repairing or replacing a surface milling cutter, the entire cutter needs to be repaired or replaced. Furthermore, when a surface milling cutter is scrapped, both the cutter body and the cutting teeth are scrapped simultaneously. This makes the repair or replacement process for surface milling cutters cumbersome and complex. Moreover, the scrapping of the entire surface milling cutter results in a certain degree of resource waste.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a milling cutter structure for surface machining.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a structure for a curved surface milling cutter, which can improve the convenience of repairing or replacing curved surface milling cutters and the resource utilization rate.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides a surface milling cutter structure, including a cutter body, a toothed structure inserted and assembled at the lower part of the cutter body, a locating pin integrally formed at the top of the toothed structure, a locating pin hole opened at the lower end of the cutter body, the locating pin inserted and assembled in the locating pin hole, a bolt group fixedly connecting the toothed structure and the cutter body, and a disassembly and assembly target rod inserted at the upper part of the cutter body, the disassembly and assembly target rod being configured to cooperate with the locating pin.

[0008] In one or more embodiments of this utility model, the cutting tooth structure is composed of a positioning cutting head, a connecting block, and cutting teeth. The positioning cutting head, the connecting block, and the cutting teeth are arranged sequentially from top to bottom, and the positioning cutting head and the cutting teeth are fixedly connected to the upper and lower end faces of the connecting block, respectively.

[0009] In one or more embodiments of this utility model, a positioning ring is integrally formed on the outer side of the connecting block. The positioning ring supports and limits the assembly and disassembly of the blade tooth structure. The positioning pin is fixedly connected to the upper end face of the positioning cutter head. The blade body and the blade tooth structure are positioned and engaged through the insertion and engagement of the positioning pin with the positioning pin hole.

[0010] In one or more embodiments of this utility model, the positioning cutter head is provided with an assembly through hole. The positioning cutter head is assembled and fixed by means of bolts passing through the assembly through hole. Both sides of the lower end of the cutter body are planar. By making the lower side of the cutter body planar, the fixing stability of the bolt group is ensured.

[0011] In one or more embodiments of this utility model, a connecting through hole is provided at the lower end of the blade body, the connecting through hole and the assembly through hole are fitted together, and the bolt group passes through the connecting through hole and the assembly through hole. The blade body and the blade tooth structure are assembled and fixed by means of the bolt group passing through the connecting through hole and the assembly through hole.

[0012] In one or more embodiments of this utility model, a insertion positioning groove is provided on the lower side of the blade body. The insertion positioning groove is located below the positioning pin hole and is configured to cooperate with the positioning blade head. The positioning blade head is inserted and positioned by the insertion positioning groove.

[0013] In one or more embodiments of this utility model, a target slot is provided on the upper part of the blade body, and the target slot is connected to a positioning pin hole. The target slot is used to limit the insertion and removal of the target rod.

[0014] In one or more embodiments of this utility model, the diameter of the target slot is smaller than the diameter of the positioning pin hole. This reduces the likelihood of the positioning pin entering the target slot during insertion, ensuring the stability of the insertion and positioning of the cutting tooth structure and the cutting body. The target rod is inserted and assembled in the target slot. The positioning pin can be inserted and positioned and disassembled by disassembling and assembling the target rod.

[0015] In one or more embodiments of this utility model, the detachable marker pole consists of two parts: a marker pole body and a pole cap. The pole cap is fixedly connected to the top of the marker pole body, and the diameter of the marker pole body is larger than the diameter of the pole cap.

[0016] In one or more embodiments of this utility model, a scale line is provided on the outer side of the marking rod, and the value of the scale line gradually increases from top to bottom. The insertion state of the positioning pin and the positioning pin hole is observed and judged by observing the scale line.

[0017] Compared with the prior art, the surface milling cutter structure disclosed in this utility model adopts a split design, which allows the cutter body and the cutting teeth to be disassembled and assembled independently. This simplifies the subsequent repair or replacement process of the surface milling cutter and improves the convenience of repairing or replacing the surface milling cutter. At the same time, the cutter body can be reused, reducing the waste of resources. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1 to 6 As shown, a surface machining milling cutter structure in one embodiment of the present invention includes a cutter body 1.

[0029] like Figures 1 to 3 As shown, a cutting tooth structure 2 is inserted and assembled at the lower part of the cutter body 1. The workpiece can be milled by rotating the cutting tooth structure 2.

[0030] like Figures 2 to 3 As shown, the cutting tooth structure 2 consists of several parts, including a positioning cutting head 201, a connecting block 202, and cutting teeth 203. The positioning cutting head 201, the connecting block 202, and the cutting teeth 203 are arranged sequentially from top to bottom, and the positioning cutting head 201 and the cutting teeth 203 are fixedly connected to the upper and lower end faces of the connecting block 202, respectively.

[0031] like Figures 2 to 3 As shown, a positioning ring 204 is integrally formed on the outer side of the connecting block 202. The positioning ring 204 can be used to support and limit the disassembly and assembly of the blade tooth structure 2.

[0032] like Figures 2 to 3 As shown, the positioning cutter head 201 has an assembly through hole. The positioning cutter head 201 is assembled and fixed by means of bolt group 4 passing through the assembly through hole.

[0033] Specifically, both sides of the lower end of the cutter body 1 are flat. By making the lower side of the cutter body 1 flat, the fixing stability of the bolt assembly 4 is ensured.

[0034] like Figures 3 to 5 As shown, a insertion positioning groove is provided on the lower side of the cutter body 1. The insertion positioning groove is located below the positioning pin hole and is configured to cooperate with the positioning cutter head 201. The positioning cutter head 201 is inserted and positioned by the insertion positioning groove.

[0035] like Figures 2 to 5 As shown, a locating pin 3 is integrally formed at the top of the cutting tooth structure 2. The locating pin 3 and the locating pin hole can be inserted and positioned to assemble the cutting body 1 and the cutting tooth structure 2, thereby improving the assembly stability of the cutting body 1 and the cutting tooth structure 2.

[0036] The locating pin 3 is fixedly connected to the upper end face of the locating cutter head 201. The locating pin 3 is inserted and positioned into the locating pin hole to connect and position the cutter body 1 and the cutter tooth structure 2.

[0037] like Figures 4 to 5 As shown, a positioning pin hole is provided at the lower end of the cutter body 1, and the positioning pin 3 is inserted and assembled in the positioning pin hole. The cooperation between the positioning pin hole and the positioning pin 3 improves the assembly stability of the cutter body 1 and the positioning cutter head 201.

[0038] like Figures 2 to 5 As shown, a bolt group 4 is fixedly connected between the cutting tooth structure 2 and the cutting body 1. The bolt group 4 assembles and fixes the cutting body 1 and the positioning cutting head 201, thereby preventing the positioning cutting head 201 from detaching and limiting its connection.

[0039] like Figures 2 to 4 As shown, a connecting through hole is provided at the lower end of the blade body 1. The connecting through hole and the assembly through hole are fitted together, and the bolt group 4 passes through both the connecting through hole and the assembly through hole. The blade body 1 and the blade tooth structure 2 are assembled and fixed by means of the bolt group 4 passing through the connecting through hole and the assembly through hole.

[0040] like Figure 2 As shown, a disassembly / removal target rod 5 is inserted into the upper part of the blade body 1, and the disassembly / removal target rod 5 is configured to cooperate with the positioning pin 3. By inserting the disassembly / removal target rod 5 into the target slot, it is possible to observe and judge whether the positioning pin 3 is properly inserted. At the same time, the positioning pin 3 can be pushed out by tapping the disassembly / removal target rod 5, thereby assisting in the disassembly of the positioning blade head 201.

[0041] In addition, a target slot is provided on the upper part of the blade body 1, and the target slot is connected to the positioning pin hole. The target slot is used to limit the insertion and removal of the target rod 5.

[0042] It is worth noting that the diameter of the target slot is smaller than the diameter of the locating pin hole. This reduces the likelihood of the locating pin 3 entering the target slot during insertion, ensuring the stability of the insertion and positioning of the cutting tooth structure 2 and the cutting body 1. The target rod 5 is inserted and assembled in the target slot. By disassembling and assembling the target rod 5, the locating pin 3 can be inserted, positioned, and disassembled as needed.

[0043] like Figure 2 As shown, the signpost 5 consists of two parts: the signpost body 501 and the signpost cap 502. The signpost cap 502 is fixedly connected to the top of the signpost body 501, and the diameter of the signpost body 501 is larger than the diameter of the signpost cap 502.

[0044] Specifically, the outer side of the marker rod 501 is provided with marking scale lines, the values ​​of which gradually increase from top to bottom. The insertion status of the positioning pin 3 and the positioning pin hole is observed and judged by observing the marking scale lines.

[0045] In practical use, during assembly, the positioning cutter head 201 and the cutter body 1 can be initially assembled by cooperating with the positioning slot. Simultaneously, the cutter body 1 and the tooth structure 2 can be auxiliaryly positioned by the insertion and cooperation of the positioning pin 3 and the positioning pin hole. Furthermore, the cutter body 1 and the positioning cutter head 201 can be connected and fixed by the bolt group 4 passing through the connecting through hole and the assembly through hole. After assembly, the insertion status of the positioning pin 3 can be observed by inserting the disassembly and assembly marker rod 5 into the marker slot and observing the marking scale lines on the marker rod 501.

[0046] When it is necessary to disassemble the tooth structure 2, the corresponding limiting frame can be used to support and limit the positioning ring 204 and the knife body 1. Then, the bolt group 4 can be disassembled. The positioning pin 3 can be disengaged from the positioning pin hole by tapping the disassembly and assembly target rod 5, thereby completing the separation state of the knife body 1 and the tooth structure 2.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
