[0021] In order to make those skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely in conjunction with the drawings.

[0022] As shown in Figures 2-4 A machining profiling clamping tool that can be quickly installed and replaced, comprising a base 1, the base 1 is fixedly installed on a machining equipment, the base 1 is provided with a mounting seat 2, the mounting seat 2 is fixedly installed with a clamping vice 3, the clamping vice 3 is provided with a positioning seat 4, the positioning seat 4 is installed with a profiling block 5, the profiling block 5 is provided with a profiling groove 51; during machining, the workpiece is placed on the profiling groove 51, the positioning seat 4 and the profiling block 5 are clamped by the clamping vice 3, and then the workpiece is clamped by the profiling block 5, so as to machine the workpiece.

[0023] The profiling block 5 is detachably connected with the positioning seat 4, so as to facilitate replacement of different profiling blocks 5 to meet the machining requirements of different workpieces. The upper end surface of the positioning seat 4 is provided with a plurality of positioning protrusions 41, and the lower end surface of the profiling block 5 is provided with a positioning groove 52 at a position corresponding to the positioning protrusion 41. The positioning protrusion 41 is clamped with the corresponding positioning groove 52. When the machining profiling clamping tool is used for machining, since the base 1, the mounting seat 2 and the clamping vice 3 are pre-installed on the machining equipment, when the clamping tool is installed, only the profiling block 5 is placed on the positioning seat 4, the positioning protrusion 41 is positioned and clamped with the positioning groove 52, and then the profiling block 5 is connected and fixed with the positioning seat 4, so that the installation process of the profiling block 5 is completed. Since the clamping vice 3 is pre-installed on the machining equipment, the machining center origin of the clamping vice 3 corresponds to the origin of the machining equipment. Therefore, after the profiling block 5 is installed on the positioning seat 4, the machining center origin does not need to be calibrated again, and the machining can be directly carried out, thereby saving the machine adjustment time. Such a structure also facilitates machining of different workpieces, and only different types of profiling blocks 5 need to be replaced. Through the cooperation of the positioning protrusion 41 and the positioning groove 52, after the different profiling blocks 5 are installed, the machining center origin does not need to be calibrated again, thereby saving the machine adjustment time and improving the machining efficiency.

[0024] In the embodiment, in order to improve the positioning accuracy, the positioning protrusions 41 on the positioning seat 4 include one horizontal positioning protrusion 41 and two vertical positioning protrusions 41, and the horizontal and vertical positioning protrusions 41 are distributed in a cross shape on the upper end surface of the positioning seat 4. The positioning grooves 52 on the profiling block 5 are one-to-one corresponding to the positioning protrusions 41 on the positioning seat 4. In other embodiments, the positioning protrusions 41 can also be any other number, as long as there is at least one horizontal positioning protrusion 41 and one vertical positioning protrusion 41.

[0025] In the embodiment, the shape of the positioning protrusion 41 is a long strip shape. In other embodiments, the positioning protrusion 41 can also be other shapes, such as an oval shape, a triangular shape, a rectangular shape or other special shapes.

[0026] In order to enable the profiling block 5 to be connected and fixed with the positioning seat 4, the positioning seat 4 is provided with a fixing screw 6 at each of the four corner positions, and the fixing screw 6 is screwed with the profiling block 5 after penetrating through the positioning seat 4. The connection and fixation of the profiling block 5 and the positioning seat 4 through the fixing screw 6 can improve the stability of the structure and facilitate disassembly and replacement of the profiling block 5. In other embodiments, the number of fixing screws 6 can also be other numbers, and the profiling block 5 and the positioning seat 4 can also adopt other detachable connection modes, such as clamping.

[0027] In order to facilitate clamping workpiece, in this embodiment, the number of positioning seat 4 is two, and each positioning seat 4 is installed with one profiling block 5, and the clamping vice 3 can drive two positioning seats 4 to approach or separate from each other. In the process of machining, when the workpiece needs to be installed to the clamping tool, the clamping vice 3 is operated to drive two positioning seats 4 to drive two profiling blocks 5 to separate from each other, and then the workpiece is placed in the profiling groove 51 in the profiling block 5; then the clamping vice 3 is operated again to drive two positioning seats 4 to drive two profiling blocks 5 to approach each other, and the workpiece is clamped and fixed by two profiling blocks 5, and then machining is carried out. The process of disassembling the workpiece is opposite to the above process of installing the workpiece, which will not be described here.

[0028] In order to facilitate assembly, four positioning holes 11 are arranged on the upper end surface of the base 1, and positioning columns 21 are arranged on the lower end surface of the mounting seat 2 at positions corresponding to the positioning holes 11, and the positioning columns 21 are inserted and fixed with the corresponding positioning holes 11; in the process of installing the mounting seat 2 to the base 1, the positioning column 21 and the positioning hole 11 are aligned, so that the positioning column 21 is inserted into the corresponding positioning hole 11, and then the base 1 and the mounting seat 2 are connected and fixed by screws. Through the cooperation of the positioning column 21 and the positioning hole 11, the mounting seat 2 and the base 1 can be quickly positioned, improving the assembly efficiency; at the same time, it is also convenient to replace different types of mounting seat 2 and clamping vice 3, so that calibration of the machining center origin is not required.

[0029] Working principle:

[0030] When installing the profiling block 5, only the positioning groove 52 on the profiling block 5 and the positioning protrusion on the positioning seat 4 are aligned, the positioning protrusion is respectively clamped into the positioning groove 52, and then the fixing screw 6 is tightened, so that the profiling block 5 and the positioning seat 4 are connected and fixed. In this way, the machining center origin of the profiling block 5 and the machining center origin of the positioning seat 4 can be aligned, so that direct machining can be carried out without adjusting the machine. Through the cooperation of the positioning groove 52 and the positioning protrusion 41, the machining requirements of different workpieces can also be met without adjusting the machine, saving the time of adjusting the machine and improving the machining efficiency.

[0031] In the process of machining, the clamping vice 3 is operated to drive two positioning seats 4 to drive two profiling blocks 5 to separate from each other, and then the workpiece is placed in the profiling groove 51 in the profiling block 5; then the clamping vice 3 is operated again to drive two positioning seats 4 to drive two profiling blocks 5 to approach each other, and the workpiece is clamped and fixed by two profiling blocks 5, and then the machining equipment can machine the workpiece on the profiling block 5. After machining is completed, the workpiece can also be taken out from the profiling block 5 by operating the clamping vice 3.

[0032] The above specific embodiments are the preferred embodiments of the utility model, and do not limit the specific implementation range of the utility model, the range of the utility model includes but is not limited to the specific embodiments, and equivalent changes made according to the utility model are within the protection range of the utility model.
