[0046] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0047] Reference below Figure 1-Figure 18 A machine tool detection device 100 according to an embodiment of the present invention is described.

[0048] like Figure 1 As shown, the machine tool detection device 100 according to the embodiment of the utility model includes: a machine body 10 and a detection mechanism 20, wherein the machine body 10 is a component that provides an installation space for the detection mechanism 20 and fixes the detection mechanism 20 on the machine tool so that the detection mechanism 20 can be fixedly connected to the machine tool; the detection mechanism 20 is mainly used to correct the geometric parameters of the machine tool, such as straightness, parallelism, verticality and angle, etc., to improve the geometric accuracy of the machine tool, thereby improving the processing accuracy of the machine tool and reducing the incidence of producing unqualified products.

[0049] Specifically, the detection mechanism 20 includes a calibration piece 21 and a connecting rod 22. The calibration piece 21 is used to calibrate the coordinate axis center of the machine tool. The calibration piece 21 is arranged on the connecting rod 22. The connecting rod 22 is rotatably arranged on the machine body 10 around a horizontally arranged rotation axis, so that the calibration piece 21 can move between multiple detection positions. When the calibration piece 21 is in multiple detection positions, the angle between the line between the calibration piece 21 and the rotation axis and the horizontal direction is different, so that the calibration piece 21 can detect different types of machine tools. For example, the number of detection positions can be two, three or more, and the detection positions can be designed according to the detection requirements of different types of machine tools. In this way, the detection mechanism 20 can meet the correction requirements of different types of machine tools, thereby improving the flexibility of the machine tool detection device 100 and increasing the applicability of the machine tool detection device 100.

[0050] When calibrating the geometric accuracy of the machine tool, first move the calibration piece 21 to the corresponding detection position according to the machine tool type, then fix the machine body 10 on the workbench of the machine tool, and then start the machine tool calibration function to start calibrating the geometric accuracy of the machine tool.

[0051] According to the machine tool detection device 100 of the embodiment of the utility model, by setting the calibration part 21 to be movable between multiple detection positions, the machine tool detection device 100 can calibrate the geometric accuracy of machine tools of different types, thereby improving the flexibility of the machine tool detection device 100 and increasing the applicability of the machine tool detection device 100.

[0052] According to some embodiments of the present invention, Figure 5-Figure 6 As shown, the multiple detection positions include: a first detection position and a second detection position. At the first detection position, the line between the calibration piece 21 and the rotation axis is a first line, and the angle between the first line and the horizontal direction is 45°; at the second detection position, the line between the calibration piece 21 and the rotation axis is a second line, and the angle between the second line and the horizontal direction is 90°.

[0053] Specifically, the calibration piece 21 is fixedly connected to the connecting rod 22, and the connecting rod 22 is rotated around the rotation axis to switch between multiple detection positions, so that the angle between the first connecting line and the horizontal direction is the angle between the connecting rod 22 and the horizontal direction. When the calibration piece 21 is in the first detection position, the detection mechanism 20 can be used to calibrate the geometric accuracy of the horizontal machine tool, and when the calibration piece 21 is in the second detection position, the detection mechanism 20 can be used to calibrate the geometric accuracy of the vertical machine tool.

[0054] According to some embodiments of the present invention, Figure 2-Figure 3 As shown, a first cavity 11 and a limiting hole 12 connected to the first cavity 11 are provided in the body 10, one end of a connecting rod 22 is provided in the first cavity 11 and the other end passes through the limiting hole 12 and extends out of the body 10, a marking component 21 is provided at the other end of the connecting rod 22, wherein the limiting hole 12 is a long hole, the limiting hole 12 has a first side wall 121 and a second side wall 122 arranged opposite to each other in the length direction, the marking component 21 is in the first detection position, the connecting rod 22 abuts against the first side wall 121, and the marking component 21 is in the second detection position, the connecting rod 22 abuts against the second side wall 122.

[0055] Specifically, the limiting hole 12 can limit the movement trajectory of the connecting rod 22, which can effectively prevent the connecting rod 22 from being offset during movement, thereby ensuring the correction accuracy of the detection mechanism 20; at the same time, the first side wall 121 and the second side wall 122 can further limit the position of the connecting rod 22, improve the accuracy of the first detection position and the second detection position, thereby further improving the correction accuracy of the machine tool detection device 100.

[0056] According to some embodiments of the present invention, Fig. 9 and Fig.12 As shown, the first side wall 121 and the second side wall 122 both include a first wall surface and a second wall surface, and the distance between the first wall surface and the second wall surface gradually decreases in the direction from the middle of the length direction of the limiting hole 12 toward both ends. In this way, the contact area between the connecting rod 22 and the first wall surface and the second wall surface can be reduced, and then the friction force of the connecting rod 22 during the movement process can be reduced, so that the contact error can be better reduced and the correction accuracy of the detection mechanism 20 can be improved.

[0057] For example Fig.12 As shown, the middle position of the limiting hole 12 is oval in shape, and the two ends are V-shaped, wherein the V-shaped structure is simple and easy to manufacture, thereby improving the production convenience of the body 10.

[0058] According to some embodiments of the present invention, Figure 3 As shown, one side of the first cavity 11 is opened to form a first opening, and the machine tool detection device 100 further includes: a cover plate 30, which is sealed at the first opening position, and the cover plate 30 is detachably connected to the machine body 10. The first opening can facilitate the installation of the detection mechanism 20 and the machine body 10, and the cover plate 30 is used to cover the first opening, which can increase the aesthetics of the machine tool detection device 100, and at the same time, it can also prevent impurities and other components from entering the first cavity 11 from the first opening to affect the calibration work of the detection mechanism 20.

[0059] According to some embodiments of the present invention, the calibration component 21 is a standard measuring ball, also called a ball gauge, which is used to calibrate the origin of the coordinate axis, which is beneficial to improve the accuracy of calibration and further improve the accuracy of machine tool geometry correction.

[0060] Furthermore, the calibration member 21 is connected to the connecting rod 22 via threads, so that the connection convenience between the calibration member 21 and the connecting rod 22 can be improved.

[0061] According to some embodiments of the present invention, Figure 3As shown, the detection mechanism 20 also includes: a first bearing 23 and a first connecting shaft 24. The connecting rod 22 is provided with a first shaft hole 221, the first bearing 23 is arranged in the first shaft hole 221, and the first connecting shaft 24 passes through the first bearing 23 and is fixed to the machine body 10. In this way, the connecting rod 22 can be fixed on the machine body 10, and can rotate around the first connecting shaft 24 relative to the machine body 10, thereby realizing the switching of the calibration member 21 between the first detection position and the second detection position, so that the detection mechanism 20 can have multiple modes, thereby increasing the flexibility of the machine tool detection device 100 and increasing the scope of application of the machine tool detection device 100; at the same time, the bearing is used to make the connecting rod 22 rotatable relative to the machine body 10, which can reduce the friction of the connecting rod 22 during the movement process, thereby reducing the loss of the connecting rod 22 and increasing the service life of the connecting rod 22.

[0062] Furthermore, for example Figure 3 As shown, there are two first bearings 23, and the two first bearings 23 are arranged at intervals in the first axial hole 221 along the axial direction of the first axial hole 221; the detection mechanism 20 also includes a first pressure block 28, and the first pressure block 28 is connected to one end of the first connecting shaft 24, and the first connecting shaft 24 passes through the first bearing 23 and is fixedly connected to the first mounting seat 16 formed on the body 10 through the first pressure block 28.

[0063] Optionally, a first mounting hole is formed on the first pressing block 28, and a second mounting hole is correspondingly formed on the first mounting seat 16; the first mounting hole and the second mounting hole are fixedly connected by a fastener 80, and the first pressing block 28 is fixed on the first mounting seat 16, so that the connecting rod 22 is fixedly connected to the body 10.

[0064] According to some embodiments of the present invention, Figure 2-Figure 3 As shown, the detection mechanism 20 further includes: an elastic member 25, one end of which is rotatably connected to the connecting rod 22 and the other end of which is rotatably connected to the machine body 10 through a second connecting shaft 26. The elastic member 25 is always in a compressed state. When the calibration member 21 is in the first detection position and the second detection position, the elastic member 25 always has a certain thrust on the connecting rod 22, so that the connecting rod 22 can be positioned at the first detection position and the second detection position, so that the detection mechanism 20 can have multiple modes to be applicable to various types of machine tools, thereby increasing the applicability of the detection mechanism 20.

[0065] Furthermore, for example Figure 3As shown, a first connecting hole is formed at one end of the elastic member 25, a second connecting hole is formed at one end of the connecting rod 22 away from the calibration member 21, and the third connecting shaft 27 is rotatably fitted in the first connecting hole and the second connecting hole, so that the elastic member 25 is rotatably connected to the connecting rod 22. The detection mechanism 20 also includes a second pressing block 29, a second mounting seat 17 is formed on the body 10, the second pressing block 29 is connected to one end of the second connecting shaft 26, and the second pressing block 29 is fixedly connected to the second mounting seat 17 by a fastener 80, so that the elastic member 25 is fixedly connected to the body 10.

[0066] Furthermore, for example Figure 3 As shown, the detection mechanism 20 also includes a retaining spring, which is sleeved on one end of the third connecting shaft 27 to prevent the third connecting shaft 27 from falling off from the first connecting hole and the second connecting hole, thereby ensuring the normal operation of the detection mechanism 20.

[0067] According to some embodiments of the present invention, Figure 1 As shown, a part of the machine body 10 is formed as a calibration ring gauge 13. The calibration ring gauge 13 is mainly used to calibrate the probe. The calibration ring gauge 13 is formed on the machine body 10, which can increase the integration of the machine tool detection device 100, reduce the number of calibration tools, and thus improve the efficiency of probe calibration, reduce the difficulty and complexity of calibration; at the same time, it can also achieve weight reduction of the detection device, and thus effectively avoid the machine tool from carrying too heavy detection tools for a long time, which is conducive to the long-term stable and effective operation of the machine tool.

[0068] According to some embodiments of the present invention, Figure 1 and Figure 16-18 As shown, the machine tool detection device 100 further includes: a cleaning member 40, the cleaning member 40 is annular, the cleaning member 40 is formed with an air flow channel 41 and an air inlet 42 and an air outlet 43 connected to the air flow channel 41, the air flow channel 41 extends in an annular shape along the circumference of the cleaning member 40, and the air outlet 43 includes a plurality of air outlets 43, and the plurality of air outlets 43 are arranged at intervals along the circumference of the cleaning member 40, and the air outlet 43 is configured to spray air flow toward the inner wall surface of the correction ring gauge 13. The sprayed air flow can clean the dirt and debris on the surface of the probe and the correction ring gauge 13, thereby effectively preventing the dirt on the surface of the correction ring gauge 13 and the probe from affecting the calibration of the probe, effectively avoiding the measurement error caused by the dirt on the surface of the correction ring gauge 13 and the probe, thereby improving the accuracy of the calibration of the probe; at the same time, it can also reduce the workload of manual intervention, thereby improving the calibration efficiency.

[0069] Furthermore, the probe and machine tool calibrated by the machine tool detection device 100 in the above embodiment can effectively improve the machining accuracy and stability of the workpiece, reduce the incidence of manufacturing unqualified products, and thus further improve production efficiency and product quality.

[0070] For example, the number of the air outlet holes 43 may be two, three or more.

[0071] According to some embodiments of the present invention, Figure 1 and Figure 16-18 As shown, the cleaning member 40 is arranged on one side of the correction ring gauge 13 in the axial direction, and the air outlet 43 extends radially inwardly of the cleaning member 40 and penetrates the inner surface of the cleaning member 40. In the radial direction from the outside to the inside of the cleaning member 40, the air outlet 43 extends obliquely toward the circumference of the cleaning member 40, and the air outlet 43 extends obliquely toward the side where the correction ring gauge 13 is located. The air outlet 43 extends obliquely toward the circumference of the cleaning member 40, so that the injected airflow can move along the circumference of the cleaning member 40, and further, a vortex can be generated on the radial inner side of the correction ring gauge 13 and the cleaning member 40, so as to increase the cleaning effect of the airflow on the correction ring gauge 13.

[0072] According to some embodiments of the present invention, Figure 4 As shown, a receiving groove 14 is provided on one side surface of the machine body 10 in the vertical direction, and a cleaning member 40 is arranged in the receiving groove 14, and the cleaning member 40 is detachably connected to the machine body 10. The machine body 10 is formed with a receiving groove 14 on one side surface where the correction ring gauge 13 is located, and the cleaning member 40 is arranged in the receiving groove 14, which can limit the installation position of the cleaning member 40, thereby improving the installation convenience of the cleaning member 40; at the same time, the cleaning member 40 is detachably connected to the machine body 10, which can also increase the convenience of disassembly, maintenance and installation of the machine body 10 and the cleaning member 40.

[0073] Optionally, the cleaning member 40 is fixedly connected to the body 10 by bolts.

[0074] According to some embodiments of the present invention, Figure 4 and Fig.11 As shown, a connecting channel 15 is formed in the body 10, and an outlet 151 of the connecting channel 15 is sealed and connected to the airflow channel 41 through a sealing ring 70, and an air pipe joint 50 is provided at the inlet of the connecting channel 15. Specifically, the connecting channel 15 is externally connected to a compressed gas pipeline through the air pipe joint 50, and the compressed gas enters the connecting channel 15 through the air pipe joint 50, and then provides the required airflow to the airflow channel 41. Among them, the outlet 151 of the connecting channel 15 is sealed and connected to the air inlet 42 of the airflow channel 41 through the sealing ring 70, which can increase the sealing of the connecting channel 15 and the airflow channel 41, effectively prevent the airflow from leaking from the connection between the connecting channel and the airflow channel 41, and thus ensure the normal operation of the cleaning member 40.

[0075] When the probe needs to be calibrated, the machine tool detection device 100 can be fixed on the machine tool workbench, and then the probe to be calibrated is inserted into the predetermined position in the calibration ring gauge 13, and then compressed gas is provided to the air flow channel 41, so that the air flow is sprayed from the air outlet of the air flow channel 41 to the surface of the calibration ring gauge 13. The air flow sprayed to the surface of the calibration ring gauge 13 is high-pressure gas, and then the air flow will accelerate on the surface of the calibration ring gauge 13, thereby forming a vortex to sweep away the dirt and impurities on the surface of the ring gauge. At the same time, the continuously ejected high-pressure gas will cause the vortex to eject from the center spiral, thereby effectively cleaning the probe in a spiral 360°, thereby improving the accuracy and precision of the probe calibration.

[0076] According to some embodiments of the present invention, Figure 4 As shown, the machine tool detection device 100 also includes: a base 60, the machine body 10 is connected to the base 60 and is located on the upper side of the base 60, the base 60 includes a magnetic suction member, and the magnetic suction member can be switched between a first state and a second state. In the first state, the base 60 is magnetically attracted to the machine tool through the magnetic suction member to be fixed to the machine tool, and in the second state, the base 60 and the machine tool have no magnetic attraction or magnetic repulsion. Among them, the base 60 uses a magnetic suction member to fix and disassemble the machine tool, which can increase the convenience of fixing and separating the base 60 from the machine tool, thereby reducing the workload of manual installation and disassembly, thereby improving the detection efficiency of the machine tool detection device 100; at the same time, the provision of the base 60 can also increase the height of the machine tool detection device 100, thereby eliminating the need to add additional tooling to raise the machine body 10, thereby reducing the use of detection aids.

[0077] Furthermore, the body 10 also includes a mounting plate, which is arranged at the bottom of the body 10, and a plurality of third mounting holes are formed on the mounting plate; a plurality of fourth mounting holes are formed on the base 60, and the third mounting holes correspond to the fourth mounting holes one by one, and the third mounting holes are fixedly connected to the fourth mounting holes by fasteners 80, so that the body 10 is fixedly connected to the base 60.

In this way, the automation of the base 60 can be increased, the complexity of fixing and disassembling the machine tool detection device 100 and the machine tool can be reduced, and the convenience of fixing and disassembling the machine tool detection device 100 and the machine tool can be improved.
