The motor is fixed on the box, and the power is transmitted to the tool system through the transmission device. The tool system includes a tool holder, a blade and the like, and is responsible for the actual cutting processing. The design of the power tool turret enables each tool position to install not only a turning tool, but also a rotary tool such as a milling cutter and a drill bit, so as to realize turning-milling combined processing.

[0003] The fault diagnosis of the numerical control machine tool is a complex and meticulous process, which aims to quickly and accurately identify and solve problems occurring in the operation of the machine tool. The key parameters in the operation process of the numerical control machine tool, such as temperature, can be collected to realize the fault diagnosis of the numerical control machine tool. By detecting the tool temperature, subsequent fault diagnosis can be facilitated.

[0004] At present, there is still a lack of a fault diagnosis device that can conveniently monitor the temperature of the tool on the power tool turret of the machining center and facilitate subsequent fault diagnosis. CONTENT OF THE UTILITY MODEL

[0005] The utility model solves the technical problem to provide a numerical control machine tool intelligent fault diagnosis device, which can conveniently monitor the temperature of the tool on the power tool turret of the machining center and facilitate subsequent fault diagnosis.

[0006] The utility model realizes the utility model purpose by adopting the following technical scheme:

[0007] A numerical control machine tool intelligent fault diagnosis device is characterized by comprising: a fixed disc fixedly connected to a power tool turret of a machining center, the fixed disc being provided with a group of uniformly distributed straight grooves, each straight groove being provided with a guide rod, and each guide rod being fixedly connected to the fixed disc; a group of sliding blocks provided in the corresponding straight grooves, each guide rod penetrating through the corresponding sliding block, and each sliding block being fixedly connected to an installation round rod; a group of telescopic rods fixedly connected to the corresponding installation round rods; and a group of temperature sensors fixedly connected to the corresponding telescopic rods. By adopting a group of temperature sensors, the temperature of the tool on the power tool turret of the machining center can be monitored conveniently. The position of the temperature sensor can be adjusted, so that the temperature sensor is away from the center of the fixed disc when the tool is disassembled and assembled, facilitating the disassembly and assembly of the tool.

[0008] As a further limitation of the technical solution, the telescopic rod comprises a square cylinder, the square cylinder is fixedly connected with the corresponding mounting round rod, a square rod is arranged in the square cylinder, and the square rod is fixedly connected with the corresponding temperature sensor. By adopting the adjustable telescopic rod, the installation position and size of the tool are adjusted, and temperature monitoring is facilitated.

[0009] As a further limitation of the technical solution, the square cylinder is screw-connected with a jack screw, the square rod is provided with a group of positioning holes, and the jack screw matches the positioning holes. By adopting the jack screw and the positioning hole, the position of the temperature sensor after adjustment is locked.

[0010] As a further limitation of the technical solution, the fixed disc is rotationally connected with an adjusting disc, one end of a group of connecting rods is rotationally connected with the adjusting disc, and the other end of each connecting rod is rotationally connected with the corresponding mounting round rod. By adopting the adjusting disc, when the adjusting disc is rotated, the positions of a group of temperature sensors are synchronously adjusted.

[0011] As a further limitation of the technical solution, the edge of the adjusting disc is fixedly connected with a power rod, the power rod is rotationally connected with a mounting block, the mounting block is bearing-connected with a screw rod, the screw rod is screw-connected with a T-shaped rod, and the T-shaped rod is rotationally connected with the fixed disc. By adopting the screw rod, when the screw rod is rotated, the rotation of the adjusting disc is facilitated.

[0012] As a further limitation of the technical solution, part of the temperature sensors are arranged in parallel with the length direction of the machining center power tool tower, and the remaining temperature sensors are arranged perpendicular to the length direction of the machining center power tool tower. The installation position of the tool is as shown in the figure, the installation direction of the temperature sensor matches the position of the tool, and the temperature of the tool is measured.

[0013] As a further limitation of the technical solution, each sliding block is fixedly connected with the fixed disc through a spring, and each spring is sleeved with the corresponding guide rod. The spring is always in a compressed state, which is beneficial to keep the temperature sensor close to the center of the fixed disc.

[0014] Compared with the related art, the intelligent fault diagnosis device for a numerical control machine tool has the following beneficial effects:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: An intelligent fault diagnosis device for CNC machine tools includes: a fixed plate 2, fixedly connected to a machining center power turret 1; the fixed plate 2 has a set of evenly distributed straight grooves 4, each straight groove 4 having a guide rod 5, and each guide rod 5 being fixedly connected to the fixed plate 2; a set of sliders 11, each disposed in a corresponding straight groove 4, each guide rod 5 passing through a corresponding slider 11, and each slider 11 being fixedly connected to a mounting rod 12; a set of telescopic rods, each fixedly connected to a corresponding mounting rod 12; and a set of temperature sensors 18, each fixedly connected to a corresponding telescopic rod. By using a set of temperature sensors 18, the temperature of the cutting tool on the machining center power turret is monitored, making it convenient to use. The position of the temperature sensors 18 is adjustable; when installing or removing the cutting tool, the temperature sensors 18 are positioned away from the center of the fixed plate 2 for easy tool installation and removal.

[0026] The temperature sensor 18 is model PT100.

[0027] The telescopic rod includes a square tube 14, which is fixedly connected to the corresponding mounting round rod 12. A square rod 16 is disposed inside the square tube 14, and the square rod 16 is fixedly connected to the corresponding temperature sensor 18. By using an adjustable telescopic rod, adjustments can be made according to the installation position and size of the tool, facilitating temperature monitoring.

[0028] The square tube 14 is threadedly connected to a set screw 15, and the square rod 16 is provided with a set of positioning holes 17, with the set screw 15 matching the positioning holes 17. By using the set screw 15 and the positioning holes 17, it is convenient to lock the position of the temperature sensor 18 after adjustment.

[0029] The fixed disk 2 is rotatably connected to the adjusting disk 3, and the adjusting disk 3 is rotatably connected to one end of a set of connecting rods 10. The other end of each connecting rod 10 is rotatably connected to the corresponding mounting rod 12. By using the adjusting disk 3, the positions of a set of temperature sensors 18 can be synchronously adjusted when it rotates.

[0030] A power rod 7 is fixedly connected to the edge of the adjusting disc 3. The power rod 7 is rotatably connected to the mounting block 6. The mounting block 6 is bearing-connected to a screw 8. The screw 8 is threadedly connected to a T-shaped rod 9. The T-shaped rod 9 is rotatably connected to the fixed disc 2. By using the screw 8, it is convenient to rotate the adjusting disc 3 when the screw 8 is rotated.

[0031] The screw 8 has a self-locking function.

[0032] Some of the temperature sensors 18 have axes parallel to the length of the machining center's power turret 1, while the remaining temperature sensors 18 have axes perpendicular to the length of the machining center's power turret 1. The installation direction of the temperature sensors 18 matches the position of the tool, facilitating temperature measurement of the tool.

[0033] The working principle of the intelligent fault diagnosis device for CNC machine tools provided by this utility model is as follows:

[0034] When disassembling the tool, rotating the screw 8 causes the mounting block 6 to move, which in turn causes the power rod 7 to swing. The power rod 7 then causes the mounting block 6 to swing, which in turn causes the screw 8 to swing. The screw 8 then causes the T-shaped rod 9 to swing, which in turn causes the adjusting disc 3 to rotate. The adjusting disc 3 then causes the connecting rod 10 to swing, which in turn causes the mounting round rod 12 to move. The mounting round rod 12 causes the slider 11 to move along the guide rod 5 within the straight groove 4. The mounting round rod 12 also causes the telescopic rod and the temperature sensor 18 to move, facilitating tool assembly and disassembly.

[0035] Example 2: This example further elaborates on Example 1. Each slider 11 is fixedly connected to the fixed disk 2 by a spring 13, and each spring 13 is respectively wrapped around the corresponding guide rod 5. The spring 13 is always in a compressed state, which helps to keep the temperature sensor 18 close to the center of the fixed disk 2.

[0036] The working principle of the intelligent fault diagnosis device for CNC machine tools provided by this utility model is as follows:

[0037] When the slider 11 moves within the straight groove 4, it drives the spring 13 to move, and the spring 13 is always in a compressed state.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
