[0024] 100. Nail box base. DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] like Figure 1 As shown, this part nail magazine base 100 is a stamping hardware. The tolerance requirements of the four features marked at point A in the figure are high, which are unstable during the stamping process and cannot meet the design requirements. Therefore, the four features marked in the figure are processed by a CNC machine tool (CNC). The CNC processing tooling of the nail magazine base 100 provided in this application is used to clamp the nail magazine base 100 to provide stable processing.

[0027] CNC machining tooling for nail box base, such as Figure 2-3 As shown, it includes a tool body 1 , on which is disposed a clamping base 2 adapted to a nail magazine base 100 . The clamping base 2 is arranged along the length direction of the tool body 1 . When clamping, the nail magazine base 100 is clamped on the clamping base 2 .

[0028] A slider mounting groove (not shown in the figure) is opened on the tooling body 1 at one end of the clamping base 2, and a tooling slider 3 is arranged in the slider mounting groove. The tooling slider 3 is located at the front end of the clamping base 2 and can slide along the length direction of the clamping base 2. A first linear spring 4 is arranged at the end of the tooling slider 3 facing away from the clamping base 2.

[0029] The tooling slider 3 is provided with protrusions 10 on both sides near the bottom, and the protrusions 10 are arranged along the length direction of the tooling slider 3. The tooling slider 3 is provided with a pressure strip 9, and preferably two pressure strips 9 are pressed on the protrusions 10 formed on both sides near the bottom of the tooling slider 3, and the pressure strips 9 are fixed to the tooling body 1 by passing through the pressure strips 9 through the third bolts 16. At this time, the pressure strips 9 can not only press the tooling slider 3, but also enable the tooling slider 3 to slide directionally along the length direction in the slider installation groove. Preferably, the model of the third bolt 16 is M4*12.

[0030] After the nail magazine base 100 is clamped, the limit rod 5 is passed through the clamping base 2. The clamping base 2 is provided with a limit hole 14. The limit hole 14 is used to pass the limit rod 5. The position of the limit hole 14 corresponds to the reference of the nail magazine base 100. Figure 4 , the nail magazine base 100 is at position B as shown in the figure. The limiting rod 5 is pressed by the elastic force of the first linear spring 4 provided on the tooling slide 3 so that it is completely in contact with the nail magazine base 100, so as to fix the nail magazine base 100 laterally along the tooling body 1. Preferably, the limiting rod 5 is a cylindrical rod, and correspondingly, the limiting through hole 14 is also a cylindrical hole.

[0031] Combination Figure 5-6 As shown, the tool body 1 is also provided with a positioning member 8 for positioning the nail magazine base 100. The nail magazine base 100 has a strip hole (not shown) in the middle of its length direction, and the positioning member 8 is used to pass through the strip hole to clamp and fix the nail magazine base 100 along the tool body 1 longitudinally.

[0032] Specifically, see Figure 6 The positioning member 8 is arranged inside the tool body 1 along the vertical direction of the base of the tool body 1 as a whole, and is located below the clamping base 2. A tool profiling groove is provided at the bottom of the tool body 1, and the positioning member 8 is located in the tool profiling groove. The positioning member 8 includes a positioning insert 81, a second linear spring 82, an insert top block 83 and a first bolt 84. One end of the positioning insert 81 passes through the bottom of the tool body 1 until it extends out of the clamping base 2, and the other end is located in the tool profiling groove inside the tool body 1 and connected to the second linear spring 82. The insert top block 83 presses against the second linear spring 82 and the positioning insert 81, and is fixed to the tool body 1 by the first bolt 84. The model of the first bolt 84 is preferably M6*25. At the same time, preferably, two groups of the positioning insert 81 and the second linear spring 82 connected thereto are provided, and the tolerance of the two limit inserts is 0 / +0.005, and the processing tolerance of the tool profiling groove is 0 / -0.005.

[0033] After the nail magazine base 100 is clamped on the clamping base 2 , the positioning insert 81 on the positioning member 8 just passes through the strip-shaped hole on the nail magazine base 100 , thereby clamping and fixing the nail magazine base 100 on the tool body 1 longitudinally.

[0034] In addition, a limiting block 85 is provided on one side of the positioning insert 81 close to the bottom, and the limiting block 85 is used to prevent the positioning insert 81 from falling off from the tooling body 1 .

[0035] Back to Figure 2 , and combined with Figure 3, a pressure plate pad 6 is also provided on the nail magazine base 100 after clamping, and the pressure plate pad 6 is used to limit the position of the limit rod 5. The inner side walls of the pressure plate pad 6 are also provided with limit grooves 13 used in conjunction with the two ends of the limit rod 5. After the pressure plate gasket is assembled on the nail magazine base 100, the limit rod 5 is located in the limit groove 13 and pressed against the inner side wall of the pressure plate pad 6. Since the machine tool processing is multi-axis processing, the parts and tooling will rotate in the machine tool, and the pressure plate pad 6 is used to prevent the limit rod 5 from falling out during the processing.

[0036] In addition, after the pressure plate pad 6 is assembled on the nail magazine base 100 , the nail magazine base 100 can also be fixed in the vertical direction of the tool body 1 .

[0037] like Figure 7 As shown, the bottom of the pressing plate pad 6 is provided with a positioning groove 12 adapted to the positioning inlay. When the pressing plate pad 6 is assembled on the nail box base 100, the top of the positioning inlay just presses against in the positioning groove 12.

[0038] In addition, the pressure plate pad 6 is fixed by a tooling pressure plate 7 swingably arranged on the tooling body 1. The tooling pressure plate 7 is located beside the clamping base 2, and the tooling pressure plate 7 is fixed to the tooling body 1 by a second bolt 11, and the tooling pressure plate 7 is pressed on the top of the pressure plate pad 6 to fix the pressure plate pad 6. Preferably, the second bolt 11 is of M6*25.

[0039] Back to Figure 2-3 The tool body 1 is also provided with fixing holes 15 at both ends. The fixing holes 15 cooperate with bolts to fix the tool body 1 on the machine tool.

[0040] The specific implementation principle of the utility model is as follows: when clamping, first clamp the positioning member 8 on the tooling body 1, then install the tooling slider 3 and the first linear spring 4, and install the pressure strip 9, so that the tooling assembly is completed. Then, clamp the nail magazine base 100 on the clamping base 2 of the tooling body 1, install the limit rod 5, and the tooling slider 3 will tighten the nail magazine base 100 through the first linear spring 4 to ensure that the nail magazine base 100 is completely in contact with the limit rod 5; then install the pressure plate pad 6, and install the tooling pressure plate 7 to fix the pressure plate pad 6 to limit the limit rod 5 from falling out. At the same time, during the process, the positioning insert 81 on the positioning member 8 passes through the nail magazine base 100 and presses against the limit groove 13 of the pressure plate pad 6. Finally, use the fixing hole 15 to assemble the tooling body 1 and the clamped nail magazine base 100 together on the machine tool, waiting for stamping.

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
