Description

Technical Field

[0001] The present invention relates to the field of production and commissioning of machine tools, and particularly to a flexible tool changing mechanism for testing purposes. Background Art

[0002] As a functional component of a machine tool, before the tool magazine is installed on the machine tool, its performance needs to be tested so that the tool magazine does not need to be separately tested when installed on the machine tool, and at the same time, the stability of the machine tool experiment can be ensured. However, for tool magazines of different specifications, the positions of their tool changing points are not the same. Even for different tool magazines of the same specification, due to machining and installation errors, there are certain deviations in the positions of their tool changing points. When conducting the performance test of the tool magazine, a connecting mechanism is required to connect the tool sleeve to the housing of the tool magazine, and at the same time, it is necessary to ensure that the tool sleeve and the tool shank are coaxial. However, due to the existence of the above problems, when people test different tool magazines, different connecting mechanisms need to be set up, which increases the cost, and the frequent disassembly and assembly of the connecting mechanism also increase the labor intensity and reduce the work efficiency. Therefore, there is a need for a method or device that can solve the above problems now. Summary of the Invention

[0003] The present invention is to solve the above technical problems and proposes a flexible tool changing mechanism that is simple in structure, ingenious in design, reasonable in layout, and can perform precise fine-tuning in three directions in three-dimensional space to adapt to the tool shank test process of various different specifications of tool magazines.

[0004] The technical solution of the present invention is: a flexible tool changing mechanism for testing purposes, characterized in that: the mechanism includes a base plate 1, two Z-axis long holes 2 are symmetrically opened on the base plate 1, a Z-axis limit bolt 3 is movably connected in the Z-axis long hole 2, and two Z-axis adjustment bolts 4 respectively matching the two Z-axis limit bolts 3 are also threadedly connected to the base plate 1, and the Z-axis adjustment bolts 4 are distributed along the Z-axis direction, and at the same time, the Z-axis adjustment bolts 4 are perpendicular to the Z-axis limit bolts 3.

[0005] A connecting plate 5 perpendicular to the base plate 1 is further provided on the base plate 1. T-shaped blocks 6 are provided at both ends of the connecting plate 5. An X-axis adjustment bolt 8 is threadedly connected to the support plate 7 of the T-shaped block 6. The X-axis adjustment bolt 8 movably passes through a light hole opened in the support plate 7. Two nuts 9 are respectively located on the end faces of both ends of the support plate 7 and are threadedly connected to the X-axis adjustment bolt 8. The end of the X-axis adjustment bolt 8 contacts the end face of the X-axis support plate 10.

[0006] An X-axis long hole 11 distributed along the X-axis direction is opened on the X-axis support plate 10. An X-axis limit bolt 12 is inserted into the X-axis long hole 11, and the X-axis limit bolt 12 is also threadedly connected to the connecting plate 5.

[0007] The end of the X-axis support plate 10 is connected with a Y-axis bushing 13. A tool holder 14 distributed along the Y-axis direction is key-connected inside the Y-axis bushing 13. The Y-axis bushing 13 is connected with a Y-axis adjustment disc 16 through a Y-axis connecting bolt 15. A Y-axis adjustment bolt 17 is threadedly connected to the Y-axis adjustment disc 16. At the same time, the Y-axis adjustment disc 16 is also connected with the end of the tool holder 14 through a tool holder bolt 18.

[0008] Compared with the prior art, the present invention has the following advantages:

[0009] For the test flexible tool changing mechanism with this structural form, its structure is simple, the design is ingenious, and the layout is reasonable. In view of various problems that occur when different tool magazines need to replace different connecting mechanisms to achieve their installation with the machine tool during performance tests, a special flexible structure is designed. It can drive the tool holder to accurately adjust in three dimensions of the three-dimensional space relative to the housing of the tool magazine to ensure that the tool holder can strictly maintain coaxiality with the tool shank. Since it can perform the above adjustments, this mechanism can be used to test multiple different tool magazines or various different specifications of tool magazines, with strong universality, which can save the cost of manufacturing different tool changing mechanisms and reduce the cost pressure on enterprises. And its manufacturing process is simple and the manufacturing cost is low. Therefore, it can be said that it has multiple advantages and is particularly suitable for popularization and application in this field, and its market prospect is very broad.

[0014] The following will describe the specific embodiments of the present invention in conjunction with the drawings. As Figures 1 to 4 shown: A test flexible tool changing mechanism includes a base substrate 1. Two Z-axis long holes 2 are symmetrically formed on the substrate 1. A Z-axis limit bolt 3 is movably connected inside the Z-axis long holes 2. Two Z-axis adjustment bolts 4 respectively matching the two Z-axis limit bolts 3 are threadedly connected to the substrate 1. And the Z-axis adjustment bolts 4 are distributed along the Z-axis direction. At the same time, the Z-axis adjustment bolts 4 and the Z-axis limit bolts 3 are perpendicular to each other.

[0015] A connecting plate 5 perpendicular to the substrate 1 is further provided on the substrate 1. T-shaped blocks 6 are provided at both ends of the connecting plate 5. An X-axis adjustment bolt 8 is threadedly connected to the support plate 7 of the T-shaped block 6. The X-axis adjustment bolt 8 is movably inserted through a light hole opened in the support plate 7. Two nuts 9 are respectively threadedly connected to the X-axis adjustment bolt 8 and located on both end faces of the support plate 7. The end of the X-axis adjustment bolt 8 contacts the end face of the X-axis support plate 10.

[0016] An X-axis long hole 11 distributed along the X-axis direction is opened on the X-axis support plate 10. An X-axis limit bolt 12 is inserted through the X-axis long hole 11, and the X-axis limit bolt 12 is also threadedly connected to the connecting plate 5.

[0017] The end of the X-axis support plate 10 is connected to a Y-axis bushing 13. A tool sleeve 14 distributed along the Y-axis direction is key-connected in the Y-axis bushing 13. The Y-axis bushing 13 is connected to a Y-axis adjustment disc 16 through a Y-axis connecting bolt 15. A Y-axis adjustment bolt 17 is threadedly connected to the Y-axis adjustment disc 16. At the same time, the Y-axis adjustment disc 16 is also connected to the end of the tool sleeve 14 through a tool sleeve bolt 18.

[0018] The working process of the flexible tool changing mechanism for experiments in the embodiment of the present invention is as follows: First, the tool sleeve 14 is installed on this mechanism, and then the substrate 1 of this mechanism is installed on the tool magazine housing. Taking the axis of the tool shank of the tool magazine as a reference, this mechanism is adjusted to drive the tool sleeve 14 to perform fine adjustments in the X-axis, Y-axis, and Z-axis directions, and finally achieve the purpose of coaxiality between the tool sleeve 14 and the tool shank. After that, the tool shank can be connected in the tool sleeve 14, and the experiment of the tool magazine operation can be carried out;

[0019] Due to machining errors and installation errors, even for different tool magazines of the same specification, there are slight deviations between the tool shank and the tool magazine housing. By using this mechanism to connect the tool sleeve 14 and the tool magazine housing, the above deviations can be compensated by adjusting the position of the tool sleeve 14 in three-dimensional space;

[0020] Similarly, for tool magazines of different specifications, this mechanism can also achieve the coaxiality adjustment between the tool sleeve 14 and the tool shank;

[0021] When adjustment in the Z-axis direction is required, the operator only needs to rotate the Z-axis adjustment bolt 4 to drive it to move along its own axial direction (i.e., the Z-axis direction). The Z-axis adjustment bolt 4 will push the Z-axis limit bolt 3 to move in the Z-axis long hole 2. Since the substrate 1 is connected to the tool magazine housing through the Z-axis limit bolt 3, when both Z-axis adjustment bolts 4 are adjusted, the substrate 1 and all the mechanisms thereon are adjusted relative to the tool magazine housing in the Z-axis direction;

[0022] When adjustment in the X-axis direction is required, the operator only needs to rotate the nut 9 to disengage both nuts 9 from the support plate 7, push the X-axis support plate 10 to adjust relative to the connecting plate 5 in the X-axis direction. After adjusting to the appropriate position, push the X-axis adjustment bolt 8. When its end contacts the X-axis support plate 10, rotate the nut 9 again to fix the X-axis adjustment bolt 8 on the support plate 7 with the two nuts 9, thus completing the positioning operation of the X-axis support plate 10. Since the connecting plate 5 and the X-axis support plate 10 are fixedly connected by the X-axis limit bolt 12, and the X-axis limit bolt 12 is movably connected in the X-axis long hole 11 formed on the X-axis support plate 10, relative displacement between the connecting plate 5 and the X-axis support plate 10 in the X-axis direction can be achieved.

[0023] When adjustment in the Y-axis direction is required, the operator can rotate the Y-axis adjustment bolt 17. Since the Y-axis adjustment bolt 17 is threadedly connected to the Y-axis adjustment disc 16, when the Y-axis adjustment bolt 17 rotates, relative displacement will occur between the Y-axis adjustment bolt 17 and the Y-axis adjustment disc 16 along its own axial direction (i.e., the Y-axis direction), thereby driving the Y-axis adjustment disc 16 and the Y-axis bushing 13 to displace in the Y-axis direction. And the Y-axis adjustment disc 16 is connected to the tool holder 14 through the tool holder bolt 18, that is, the tool holder 14 will also displace relative to the Y-axis bushing 13 in the Y-axis direction together with the Y-axis adjustment disc 16.

[0024] The combination of the above three-direction adjustments can achieve precise adjustment of the tool holder 14 relative to the tool magazine housing in three-dimensional space, thereby ensuring that the tool holder 14 can be coaxial with the tool shank on the tool magazine.
