Description

[0001] The invention relates to a wrench device equipped with a positioning aid with the possibility of facilitating the disassembly and assembly of a tool, in particular to an easy-to-handle wrench device equipped with a positioning aid with the possibility of facilitating the disassembly and assembly of a tool.

[0002] To meet the various functions, the structure of the workpiece is becoming increasingly complex. When machining the workpiece with a spindle-driven tool, it is often necessary to use multiple tools with different machining purposes for cutting or machining the workpiece. Therefore, different structures of the workpiece with different shapes for different functions can be machined in different parts of the workpiece.

[0003] In the machining industry, a tool magazine device is generally arranged in the machining system to store a large number of tools for different machining purposes. As shown in Fig. 7 and Fig. 8, a tool magazine device includes a tool holder drive mechanism 60, a tool holder 70 driven by the tool holder drive mechanism 60, and at least one tool sleeve assembly 80 mounted on the tool holder 70.

[0004] The respective tool sleeve assembly 80 serves to hold a tool holder 90 and comprises a tool sleeve seat 81, a tool sleeve body 82 inserted into the tool sleeve seat 81, and a fastening cover 83 screwed to the tool sleeve body 82. The knife bar 90 is equipped with a knife 100, and the knife bar 90 is inserted into the knife sleeve body 82.

[0005] At the Fig. 7 and Fig. In the conventional tool sleeve assembly 80 shown in Fig. 8, the user must hold two wrenches, each clamped to the tool sleeve body 82 and the attachment cover 83, with both hands to rotate the tool sleeve body 82 and the attachment cover 83 relative to each other to release and change the tool 100.

[0006] However, in some work environments with limited space, it is difficult to rotate the two wrenches with both hands. Therefore, it is clear that the structure of the conventional tool sleeve assembly 80 still has room for reinforcement and improvement.

[0007] The invention is based on the object of creating a wrench device equipped with a positioning aid with the possibility of facilitating the disassembly and assembly of a tool, with which wrench device the disassembly and assembly of a tool is facilitated.

[0008] The object is achieved according to the invention by a wrench device equipped with a positioning aid with the possibility of facilitating the disassembly and assembly of a tool with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

[0009] The wrench device according to the invention, equipped with a positioning aid and capable of facilitating the disassembly and assembly of a tool, comprises a tool sleeve assembly comprising a tool sleeve body that serves to receive a tool holder and has a clamping part; a positioning element that is detachably arranged in the tool sleeve assembly and comprises a plate and at least one limiting projection, wherein the limiting projection is arranged on a surface of the plate;and an auxiliary key having a clamping recess and at least one limiting recess, wherein the edge surface of the clamping recess and the clamping part can be clamped together, wherein the clamping recess has an opening located on the circumference of the auxiliary key, wherein the edge surface of the respective limiting recess is located on one side of the clamping recess and can be clamped with the respective limiting projection, wherein the respective limiting recess has an opening located on the circumference of the auxiliary key, wherein the opening of the respective limiting recess and the opening of the clamping recess point in the same direction.;

[0010] The wrench device according to the invention, equipped with a positioning aid and allowing for easier tool assembly and disassembly, has the following advantages. According to the invention, the auxiliary wrench can be mounted on one side of the tool sleeve assembly in confined spaces such that the clamping part of the tool sleeve body is inserted into the clamping recess of the auxiliary wrench and is thus clamped to the edge surface of the clamping recess, and the limiting projection of the positioning element is inserted into the limiting recess of the auxiliary wrench and is thus clamped to the edge surface of the limiting recess. This prevents rotation of the tool sleeve body.By preventing the tool sleeve body from rotating using the auxiliary wrench, the user can handle the wrench with one or both hands if space allows, making it easier for the user to exert force on the wrench. This allows the tool sleeve assembly's mounting cover to be rotated more easily, making tool changes easier.

[0012] The objects, features, and advantages of the present invention are explained in more detail below with reference to the detailed description of an exemplary embodiment and the accompanying drawings. The invention is not intended to be limited to the features apparent from the description and the drawings.

[0013] As in Fig. 1 to Fig. As shown in Figure 3, a wrench device according to the invention, equipped with a positioning aid and providing the option for facilitated removal and assembly of a tool, is mounted in a tool holder 70 of a tool magazine device. The wrench device according to the invention, equipped with a positioning aid and providing the option for facilitated removal and assembly of a tool, comprises a tool sleeve assembly 10, a positioning element 20, and an auxiliary wrench 30.

[0014] As in Fig. 1 to Fig. 3, the tool sleeve assembly 10 is mounted on a tool holder 70 and serves to hold a tool receptacle 90. A tool 100 is mounted in the tool receptacle 90. The tool sleeve assembly 10 comprises a tool sleeve seat 11, a tool sleeve body 12 inserted into the tool sleeve seat 11, and a fastening cover 13 screwed to the tool sleeve body 12. The tool sleeve body 12 serves to hold the tool 90 and comprises a clamping part 120 which comprises a plurality of pairs of clamping surfaces, wherein each pair of clamping surfaces comprises two clamping surfaces 121 which are arranged parallel to one another and whose surfaces face away from one another. The details of the construction of the tool sleeve assembly 10 are known and will therefore not be explained further here.

[0015] As in Fig. 1 to Fig. 3, the positioning element 20 is detachably arranged by means of bolts on the upper part of the tool sleeve seat 11 of the tool sleeve assembly 10. The positioning element 20 comprises a plate 21, two limiting projections 22, and two positioning projections 23. The plate 21 comprises two surfaces arranged facing away from each other, wherein one of the surfaces of the plate 21 is in contact with the upper part of the tool sleeve seat 11, while the two limiting projections 22 and the two positioning projections 23 are formed on the other surface 211 of the plate 21.

[0016] As in Fig. 1 to Fig. As shown in Figure 3, the two limiting projections 22 of the positioning element 20 are arranged opposite one another and have a rectangular profile. Each positioning projection 23 has an arcuate support surface 231 facing the periphery of the plate 21. The two positioning projections 23 are arranged opposite one another, with the surfaces of the two support surfaces 231 of the two positioning projections 23 facing away from each other.

[0017] As in Fig. 1 to Fig. 3, the auxiliary key 30 serves to prevent rotation of the tool sleeve body 12. The auxiliary key 30 is plate-shaped and includes a clamping recess 31, two limiting recesses 32, a positioning recess 33, and a through hole 34. The clamping recess 31 and the clamping part 120 of the tool sleeve body 12 are profiled correspondingly to one another so that the clamping part 120 can be inserted into the clamping recess 31 and thus clamped with the edge surface of the clamping recess 31. The clamping recess 31 includes an opening located on the circumference of the auxiliary key 30, a lower surface 311 arranged opposite the opening, and two clamping support surfaces 313 arranged opposite one another and parallel to one another. The clamping support surfaces 313 of the clamping recess 31 can each be supported on the two clamping surfaces 121 of the respective clamping surface pair.

[0018] As in Fig. 1 to Fig. 3, the two limiting recesses 32 of the auxiliary key 30 are each located on two opposite sides of the clamping recess 31. The respective limiting recess 32 and the respective limiting projection 22 are profiled correspondingly to one another such that the respective limiting projection 22 can be inserted into the respective limiting recess 32 and thus clamped to the edge surface of the limiting recess 32. The limiting recess 32 comprises an opening located on the circumference of the auxiliary key 30, wherein the opening of the respective limiting recess 32 and the opening of the clamping recess 31 point in the same direction.

[0019] As in Fig. 1 to Fig. 4, the positioning recess 33 of the auxiliary key 30 is formed on the lower surface 311 of the clamping recess 31 and includes a positioning support surface 331. The positioning recess 33 and the respective positioning projection 23 are profiled correspondingly to one another such that the respective positioning projection 23 can be inserted into the positioning recess 33 and thus clamped to the edge surface of the positioning recess 33. The positioning support surface 331 of the positioning recess 33 corresponds in profile to the arcuate support surface 231 of the respective positioning projection 23 and is therefore also arcuate. Furthermore, the positioning support surface 331 can be supported on the support surface 231 of the respective positioning projection 23. The through hole 34 of the auxiliary key 30 and the clamping recess 31 are each adjacent to the two opposite sides of the auxiliary key 30.

[0020] To replace a tool 100 mounted in the tool holder 90, Fig. 1 to Fig. 4 and Fig. 6. The user mounts the auxiliary key 30 on the positioning element 20 in such a way that the clamping part 120 of the tool sleeve body 12 is inserted into the clamping recess 31 of the auxiliary key 30 and is clamped with the edge surface of the clamping recess 31, that the edges of the two limiting recesses 32 of the auxiliary key 30 are each inserted onto the two limiting projections 22 of the positioning element 20 screwed onto the tool sleeve seat 11 and are clamped with the two limiting projections 22, that the edge surface of the positioning recess 33 of the auxiliary key 30 is inserted onto the one positioning projection 23 of the positioning element 20 and is clamped with the same, and that the positioning support surface 331 of the positioning recess 33 is supported on the support surface 231 of the positioning projection 23.

[0021] As in Fig. 3 to Fig. 5, the two clamping support surfaces 313 of the clamping recess 31 are each supported on both clamping surfaces 121 of one pair of clamping surfaces of the clamping part 120, and the edge surface of the respective limiting recess 32 is placed onto the corresponding limiting projection 22 and clamped thereto in such a way that the tool sleeve body 12 cannot rotate relative to the positioning element 20 and the tool sleeve seat 11. The user can now insert a wrench into the fastening cover 13 of the tool sleeve assembly 10 such that the wrench remains stuck in the fastening cover 13. The fastening cover 13 is loosened with the wrench so that the tool 100 mounted in the tool holder 90 can be replaced.

[0022] As in Fig. 4 and Fig.As shown in Figure 5, the surfaces of the two support surfaces 231 of the two positioning projections 23 of the positioning element 20 are arranged facing away from each other. The user can optionally mount the auxiliary wrench 30 on the provided side of the tool sleeve assembly 10, which side has less space, and handle the auxiliary wrench 30 on the provided side thereof, which side has more space, to loosen or tighten the fastening cover 13 and thus replace the tool 100.

[0023] Compared with the conventional tool sleeve assembly 80, in which the user must hold two wrenches with both hands to loosen and tighten the tool sleeve body 82 and the fastening cover 83, the wrench device according to the present invention is advantageous in that the auxiliary wrench 30 can be mounted on the side of the tool sleeve assembly 10 with less space to prevent the tool sleeve body 12 from rotating. Thus, the user does not have to handle the auxiliary wrench 30 in confined spaces and can handle the auxiliary wrench 30 with one or both hands in sufficient space. In this way, force can be more easily exerted on the auxiliary wrench 30 to rotate the fastening cover 13. Thus, the replacement of the tool 100 is advantageously carried out with reduced labor and effort.

[0024] Furthermore, the two positioning projections 23 on the positioning element 20 are arranged opposite one another, with the surfaces of the two support surfaces 231 facing away from each other. This has the advantage that the positioning support surface 331 of the positioning recess 33 can be brought into contact with the support surface 231 of the corresponding positioning projection 23, regardless of which side of the tool sleeve assembly 10 the auxiliary wrench 30 is mounted. This ensures that the auxiliary wrench 30 is clamped to the positioning element 20 to reliably prevent further rotation of the tool sleeve body 12.

[0025] In the preferred embodiment of the invention, the positioning element 20 is provided with two limiting projections 22 and two positioning projections 23, and the auxiliary key 30 is provided with two limiting recesses 32. As long as rotation of the tool sleeve body 12 can be reliably prevented, it is also conceivable in the embodiment that the positioning element 20 is provided with a single limiting projection 22 and a single positioning projection 23, and the auxiliary key 30 is provided with a single limiting recess 32. According to the invention, the number of limiting projections 22, positioning projections 23, and limiting recesses 32 is not limited to a specific number.

[0026] Although the present invention has been described in detail using an exemplary embodiment, it will be understood by those skilled in the art that the invention is not limited to this exemplary embodiment. Rather, modifications are possible such that individual features can be omitted or different combinations of features can be implemented without exceeding the scope of the appended claims. The disclosure of the present invention includes all combinations of the individual features presented.
