Description

Technical Field

[0001] This utility model relates to the field of machine tool accessories technology, specifically to a machining tool that can be quickly disassembled and assembled. Background Technology

[0002] The chisel pin is a crucial component of a hydraulic breaker. Its function is to secure the chisel, ensuring stable engagement with the breaker's piston during crushing operations. If the chisel pin is machined incorrectly, the machined arc may be misaligned, preventing the breaker from fully compressing the working surface. This results in the piston's force not being fully transmitted to the chisel tip, and in severe cases, may even break the cylinder bolt, affecting the breaker's normal operation and lifespan.

[0003] The traditional method for machining the flat pin of the drill rod is to use a right-angle milling cutter to machine it sequentially, or to use an integral ball milling cutter to machine it in one piece. However, for different drill rods with different fillet radii (see...),... Figure 4 As shown, different cutting tools need to be changed, which requires the machine tool to have enough tool positions for storage and replacement. If it is a special machine, the changeover is even more complicated. After changing the type of chisel, since there is no tool magazine, the operator needs to remove all the tools on both sides of the spindle before replacing them with new tools, which increases production and labor costs. Utility Model Content

[0004] This utility model addresses the existing technical problems by providing a machining tool that can be quickly disassembled and assembled.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A machining tool that can be quickly disassembled and assembled includes a tool body, a tool block one and a tool block two. The tool body is provided with a plurality of positioning grooves in the circumferential direction. The tool block one and the tool block two are detachably installed in the positioning grooves. A first blade is installed on the tool block one and a second blade is installed on the tool block two.

[0006] Based on the above technical solution, the present invention can further improve the above technical solution as follows: Furthermore, the first blade block and the second blade block are arranged circumferentially at intervals.

[0007] Furthermore, there is one first blade and two second blades.

[0008] Furthermore, the blade body is provided with a first positioning groove and a second positioning groove circumferentially spaced. The first blade block is detachably installed in the first positioning groove by fasteners, and the second blade block is detachably installed in the second positioning groove by fasteners.

[0009] Furthermore, the positioning groove includes a first positioning wall, a second positioning wall, and a third positioning wall that are connected to each other, and an avoidance groove is formed between the first positioning wall and the third positioning wall.

[0010] Furthermore, the third positioning wall includes a horizontal positioning surface and an inclined positioning surface, wherein the horizontal positioning surface is adjacent to the clearance groove.

[0011] The beneficial effects of this utility model are: the first and second blades are detachably mounted on the blade body, and different specifications of blades can be replaced by replacing the first and second blades, thereby meeting the processing of various arcs. The replacement is convenient and quick, improving processing efficiency and reducing processing costs. Attached Figure Description

[0014] Reference Figures 1 to 3 As shown, this utility model discloses a quick-assembly and disassembly machining tool, including a tool body 10, a first tool block 20, and a second tool block 30. The tool body 10 has multiple positioning grooves circumferentially arranged. The first tool block 20 and the second tool block 30 are detachably installed in the positioning grooves. A first blade 21 is installed on the first tool block 20, and a second blade 31 is installed on the second tool block 30. In this embodiment, there is one first blade 21 and two second blades 31. During machining, one first blade 21 and two second blades 31 form a complete machining arc on the workpiece, ensuring the machining quality of the workpiece. In practical use, when machining arcs of different specifications is required, it is only necessary to remove the first tool block 20 and the second tool block 30 from the positioning grooves and replace them with the first tool block 20 and the second tool block 30 equipped with blades of the corresponding specifications. It is not necessary to replace the entire tool, which greatly improves machining efficiency and reduces machining costs.

[0015] In other alternative embodiments, the appropriate number of first blades 21 and second blades 31 can be selected according to the shape of the arc to be processed to meet the processing requirements of different arcs.

[0016] The first cutting tool 20 and the second cutting tool 30 are circumferentially spaced apart. This improves processing efficiency and cycle time, and further reduces processing costs.

[0017] The cutter body 10 is circumferentially spaced with a first positioning groove 11 and a second positioning groove 12. The first cutter block 20 is detachably mounted in the first positioning groove 11 using fasteners, and the second cutter block 30 is detachably mounted in the second positioning groove 12 using fasteners. The first positioning groove 11 and the second positioning groove 12 respectively position the first cutter block 20 and the second cutter block 30, and they are fixed using fasteners such as screws or bolts, ensuring the stability and firmness of the installation of the first cutter block 20 and the second cutter block 30, thereby ensuring the firmness of the installation of the first blade 21 and the second blade 31, and guaranteeing machining quality.

[0018] The positioning groove includes a first positioning wall, a second positioning wall, and a third positioning wall that are connected to each other. The first and second positioning walls are vertically arranged, while the third positioning wall is horizontally arranged. A clearance groove 13 is formed between the first and third positioning walls. The clearance groove 13 can effectively prevent interference between the cutting block and the edge of the positioning groove during installation, providing operating space for quick alignment of the cutting block and improving the convenience of installation.

[0019] The third positioning wall includes a horizontal positioning surface and an inclined positioning surface, with the horizontal positioning surface adjacent to the clearance groove 13. This further improves the positioning effect of tool block 20 and tool block 30, preventing them from shaking and ensuring machining quality. The horizontal positioning surface provides stable support for the tool blocks, while the inclined positioning surface helps guide the tool blocks smoothly into the positioning groove, further improving assembly efficiency. In actual operation, the operator only needs to align tool block 20 and tool block 30 with the corresponding positioning grooves and gently push them in until the fasteners can be installed smoothly to complete the tool block replacement. The entire process is simple and quick, requiring no complex adjustments or calibrations, greatly saving tool change time and improving production efficiency. At the same time, since tool block 20 and tool block 30 are detachable, tool maintenance and upkeep become more convenient, reducing maintenance costs and extending tool life.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
