DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The technical means employed in the present invention to achieve the object will be described below with reference to the drawings and preferred embodiments of the present invention.

[0012] As shown in Figures 1 to 3, the positioning auxiliary wrench device of the present invention for easily attaching and detaching a tool is provided in a tool holder 70 of a tool magazine device, and a preferred embodiment of the positioning auxiliary wrench device for easily attaching and detaching the tool has a tool case assembly 10, a positioning member 20, and an auxiliary wrench 30.

[0013] As shown in Figs. 1 to 3, the tool case assembly 10 is provided on the tool holder 70 and holds an arbor 90 on which a tool 100 is attached. The tool case assembly 10 has a tool case seat 11, a tool case body 12 inserted into the tool case seat 11, and a fixed cover 13 screwed to the tool case body 12. The tool case body 12 with an engagement portion 120 houses the arbor 90. The engagement portion 120 has a plurality of pairs of engagement surfaces each including two engagement surfaces 121 parallel to each other and facing in opposite directions. The detailed structure of the tool case assembly 10 is a conventional technique, and will not be described in detail in the present invention.

[0014] As shown in Figures 1 to 3, the positioning member 20 is removably attached to the top of the tool case seat 11 of the tool case assembly 10 by a screw, and has a plate body 21, two regulating protrusions 22, and two positioning protrusions 23, of which the plate body 21 has two surfaces facing in opposite directions, one of which contacts the top of the tool case seat 11, and the two regulating protrusions 22 and the two positioning protrusions 23 are both formed on the other surface 211 of the plate body 21.

[0015] 1 to 3, the two restricting protrusions 22 of the positioning member 20 are positioned opposite each other, and each restricting protrusion 22 has a rectangular outline. Each positioning protrusion 23 is arc-shaped and has an abutment surface 231 facing the peripheral edge of the plate body 21. The two positioning protrusions 23 are positioned opposite each other, and each abutment surface 231 faces in the opposite direction.

[0016] 1 to 3, the auxiliary wrench 30 can prevent the tool case body 12 from rotating. The auxiliary wrench 30 is a plate body and has an engagement recess 31, two regulating recesses 32, a positioning recess 33, and a hole 34, and the contour of the engagement recess 31 that engages with the engagement portion 120 corresponds to the contour of the engagement portion 120 of the tool case body 12. The engagement recess 31 has an opening located on the periphery of the auxiliary wrench 30, a bottom surface 311 facing the position of the opening, and two engagement abutment surfaces 313 that are positioned opposite to each other and parallel to each other, and the two engagement abutment surfaces 313 respectively abut against the two engagement surfaces 121 of each pair of engagement surfaces.

[0017] 1 to 3, the two restricting recesses 32 of the auxiliary wrench 30 are located on opposite sides of the engaging recess 31, and the contour of each restricting recess 32 corresponds to the contour of each restricting protrusion 22, so that each restricting recess 32 can engage with each restricting protrusion 22. Also, each restricting recess 32 has an opening located on the periphery of the auxiliary wrench 30, and the opening of each restricting recess 32 and the opening of the engaging recess 31 face in the same direction.

[0018] 1 to 4, the positioning recess 33 of the auxiliary wrench 30 is formed on the bottom surface 11 of the engagement recess 31 and has a positioning abutment surface 331, and the contour of the positioning recess 33 that engages with each positioning protrusion 23 corresponds to the contour of each positioning protrusion 23. The positioning abutment surface 331 of the positioning recess 33 faces the bottom surface 11 of the engagement recess 31 and is arc-shaped to correspond to the arc-shaped abutment surface 231 of each positioning protrusion 23, and abuts against the abutment surface 231 of each positioning protrusion 23. Also, the perforation 34 and the engagement recess 31 of the auxiliary wrench 30 are adjacent to opposite sides of the auxiliary wrench 30, respectively.

[0019] As shown in Figures 1 to 4, when replacing a tool 100 attached to an arbor 90, an operator engages the engagement recess 31 of the auxiliary wrench 30 with the engagement portion 120 of the tool case main body 12, engages the two regulating recesses 32 of the auxiliary wrench 30 with the two regulating protrusions 22 that are locked to the positioning member 20 of the tool case seat 11, respectively, and attaches the auxiliary wrench 30 to the positioning member 20 so that the positioning recess 33 of the auxiliary wrench 30 engages with one of the positioning protrusions 23 of the positioning member 20, thereby abutting the positioning abutment surface 331 of the positioning recess 33 against the abutment surface 231 of the positioning protrusion 23.

[0020] 3 to 5, the two engagement abutment surfaces 313 of the engagement recess 31 are respectively brought into contact with a pair of engagement surfaces 121 of the engagement portion 120. As a result, each regulating recess 32 is engaged with the corresponding regulating protrusion 22, and the tool case body 12 cannot rotate relative to the positioning member 20 and the tool case seat 11. In this manner, an operator can replace the tool 100 attached to the arbor 90 by engaging a wrench with the fixed lid 13 of the tool case assembly 10 and loosening the fixed lid 13.

[0021] In addition, as shown in Figures 4 and 5, the two abutment surfaces 231 of the two positioning protrusions 23 of the positioning member 20 face in opposite directions, so that an operator can attach the auxiliary wrench 30 to the side of the tool case assembly 10 having a narrower space and operate the wrench on the side of the tool case assembly 10 having a larger space, thereby replacing the tool 100 by loosening or tightening the fixed lid 13.

[0022] Normally, an operator loosens or tightens the tool case body 82 and the fixed cover 83 while holding two wrenches with both hands. However, according to the present invention, by attaching the auxiliary wrench 30 to the narrow side of the tool case assembly 10, the tool case body 12 can be prevented from rotating. This not only avoids the inconvenience of the operator having to operate the wrench in a narrow operating area, but also allows the operator to operate the wrench with one or both hands in a sufficient space and easily apply force to the wrench to turn the fixed cover 13, making it easier to replace the tool 100.

[0023] Furthermore, the positioning member 20 is provided with two positioning protrusions 23 positioned opposite each other, and the two abutment surfaces 231 of the two positioning protrusions 23 face in opposite directions. Therefore, regardless of which side of the tool case assembly 10 the auxiliary wrench 30 is attached to, the positioning abutment surface 331 of the positioning recess 33 can be abutted against the abutment surface 231 of the positioning protrusion 23. This allows the auxiliary wrench 30 to be stably engaged with the positioning member 20, and reliably prevents rotation of the tool case main body 12.

[0024] Furthermore, in the preferred embodiment of the present invention, the positioning member 20 is provided with two restricting protrusions 22 and two positioning protrusions 23, and the auxiliary wrench 30 is provided with two restricting recesses 32, but as long as the tool case body 12 can be reliably prevented from rotating in practice, the positioning member 20 may be provided with one restricting protrusion 22 and one positioning protrusion 23, and the auxiliary wrench 30 may be provided with one restricting recess 32. In other words, in the present invention, there is no limit to the numbers of restricting protrusions 22, positioning protrusions 23, and restricting recesses 32. [Explanation of symbols]
