[0026] like Figure 1 , Figure 2 and Figure 3As shown, a tool changing and positioning adjustment device for a machining center includes a centering standard part A1, a centering standard part B2, a positioning mandrel 4, and a positioning sleeve 3. The centering standard part A1 is mounted on the spindle. In this embodiment, the installation of the centering standard part A1 and the spindle is prior art and will not be described in detail. A central through hole is provided on the centering standard part B2, and multiple tool retaining grooves 7 are provided on the outer circumference of the centering standard part B2. The centering standard part B2 is mounted on the tool arm through the tool retaining grooves 7. In this embodiment, the connection between the centering standard part B2 and the tool arm is also prior art and will not be described in detail. The top of the positioning sleeve 3 is fitted into the central through hole of the centering standard part B2. The top of the positioning mandrel passes through the positioning sleeve 3 and is fitted into the central through hole of the centering standard part A1. During tool changing and adjustment, the centering standard part A1 is first connected to the spindle, thus making the central through hole of the centering standard part A1 coaxial with the spindle. Then the centering standard part A1 is fitted into the tool arm. The center standard part B2 is installed on the tool arm through the tool slot 7. The tool arm rotates 90° to the spindle tool change position. At this time, the operator is not aware that the center through hole of the center standard part A1 is coaxial with the center through hole of the center standard part B2. In this embodiment, the center through hole of the center standard part A1 is smaller than the center through hole of the center standard part B2. Therefore, the operator can move the spindle in the X and Y directions and visually ensure that the center through hole of the center standard part A1 is located within the range of the center through hole of the center standard part B2 on the axial projection plane. Then, the positioning sleeve 3 is fitted into the positioning mandrel 4, and the positioning mandrel 4 is inserted into the center through hole of the center standard part A1 in sequence through the center through hole of the center standard part B2. At this time, if the coaxiality of the center standard part A1 and the center standard part B2 cannot be met, the top end face of the positioning sleeve 3 will interfere with the bottom end face of the center standard part B2. Then, the spindle X and Y directions are adjusted. Figure 2 As shown, the misalignment space 8 formed by the arbitrary intersection of the outer circle of the positioning sleeve 3 and the center through hole of the centering standard part B2 becomes smaller and smaller until there is no obvious misalignment space 8 visible to the naked eye. Then, the X and Y directions of the spindle are finely adjusted so that the positioning sleeve 3 can be easily inserted into the through hole of the centering standard part B2. At this time, the tool change position adjustment is completed.
[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the top of the positioning mandrel 4 is provided with a tapered guide portion 5. Through the tapered guide portion 5, the positioning mandrel 4 can easily pass through the center through hole of the centering standard part B2 and facilitate the engagement of the positioning mandrel 4 with the center through hole of the centering standard part A.
[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the bottom of the positioning mandrel 4 is provided with an auxiliary disassembly hole. The auxiliary disassembly hole is a horizontal through hole. After the tool change position is adjusted, a shaft is inserted into the auxiliary disassembly hole, and then an axial force is applied downward to separate the positioning mandrel 4 from the centering standard part A1.
[0029] In this embodiment, the central through hole of the centering standard part A1 and the positioning mandrel 4 are connected by a transition fit, thereby ensuring the coaxiality of the positioning mandrel 4 and the spindle during the adjustment process, and thus ensuring the reliability of the tool change position adjustment.
[0030] In this embodiment, the center through hole of the centering standard part B2 and the positioning sleeve 3 are connected by a clearance fit, which facilitates the assembly and disassembly of the positioning sleeve 3 and the centering standard part B2. After the tool change position is adjusted, the positioning sleeve 3 can be easily removed. Furthermore, as... Figure 4 As shown, the bottom of the positioning sleeve 3 is provided with an anti-slip part 6, and the anti-slip part 6 is located below the centering standard part B2. Preferably, the anti-slip part 6 is knurled. The operator can hold the anti-slip part 6 of the positioning sleeve 3 and then apply a slight downward force to easily separate the positioning sleeve 3 from the centering standard part B2.
[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the center through hole of the centering standard part B2 has an inner chamfer, and the top outer circumference of the positioning sleeve 3 has an outer chamfer, which facilitates the installation of the positioning sleeve 3 and the centering standard part B2.
[0032] In this embodiment, the positioning sleeve 3 and the positioning mandrel 4 are in clearance fit, which facilitates the assembly and disassembly of the positioning sleeve 3 and the positioning mandrel 4.
[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
