Description

Technical Field

[0002] The intelligent informatization of CNC machine tools is the development direction of machine tool processing, and intelligent modules have become an indispensable application for the development of the machine tool industry. The intelligent toolholder is a sensor integrated on the toolholder of an ordinary machining center, which can monitor the state of tool force during machining in real time, and analyze and process the monitored data to optimize the machine tool processing parameters to achieve the purpose of optimizing the machining surface quality. The data collection and use of the intelligent toolholder are carried out on the CNC machine tool. Whether it is testing the intelligent toolholder or demonstrating its function, the workpiece needs to be processed in real time by the CNC machine tool. The theoretical calculated force needs to be compared with the data collected by the intelligent toolholder to verify the accuracy of the data collected by the intelligent toolholder.

[0035] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0036] like Figure 1 and Figure 2 As shown, this embodiment includes a housing 1 , a tool handle fixing module 2 , a test force applying module 3 and an electrical control box 4 , and the tool handle fixing module 2 , the test force applying module 3 and the electrical control box 4 are all installed in the housing 1 .

[0037] The housing 1 includes a bottom plate 11 and a cubic outer cover 12. The bottom plate 11 is a rectangular plate with four footrests at the bottom. A window is provided on the front panel of the outer cover 12 for displaying the internal structure, and a transparent protective glass is provided at the window. Four lifting rings 13 are provided on the top of the outer cover 12 to facilitate the lifting and transportation of the entire device.

[0038] like Figure 2 As shown, two parallel portal frames are provided on the base inside the outer cover 12, namely the first portal frame 14 and the second portal frame 15. A support rod 16 passing through the outer cover 12 upwards is provided on the cross bars of the two portal frames, and the lifting ring 13 is fixed on the top of the support rod 16.

[0039] like Figure 2 and Figure 3 As shown, the tool handle fixing module 2 includes a crossbeam frame 21 and a positioning unit 23. The crossbeam frame 21 generally spans the shell 1. In this embodiment, the crossbeam frame 21 is the crossbar of the first gantry frame 14. The positioning unit 23 is fixed to the top surface of one end of the crossbeam frame 21, and is located in a corner inside the entire shell 1. The crossbeam frame 21 at the positioning unit 23 is provided with a mounting hole for passing the intelligent tool handle 5 to be tested. The intelligent tool handle 5 to be tested includes a tool handle body 5a and a tool mounting portion 5b. The tool handle body 5a is clamped and fixed by the positioning unit 23, and the tool mounting portion 5b passes downward through the mounting through hole.

[0040] The specific installation structure of the positioning unit 23 and the intelligent tool handle 5 to be tested is as follows: Figure 3The positioning unit 23 includes a positioning block 231 and a positioning key 232. The side of the handle body 5a is provided with at least two positioning grooves 51. In this embodiment, there is one positioning groove 51 on each side. Figure 4 As shown. The number of positioning blocks 231 corresponds to the number of positioning slots 51, which is two. The positioning block 231 is an L-shaped plate, and the bottom is fixed to the crossbeam frame 21 by bolts. A key slot 233 corresponding to the position of the positioning slot 51 is provided on the vertical surface of the L-shaped plate. Therefore, the key slot 233 can cooperate with the positioning slot 51 to install the positioning key 232. The two ends of the positioning key 232 are respectively embedded in the corresponding positioning slot 51 and the key slot 233, so as to form radial and axial fixation for the handle body 5a, and also prevent the intelligent handle from rotating in a circle. A pressure plate 22 is also provided at the top of the positioning unit 23, and a mounting hole is provided in the center of the pressure plate 22. The pressure plate 22 is connected to the top surface of the positioning block 231 by bolts around it. After the pressure plate 22 is fixed, the top of the handle body 5a passes through the mounting hole, and the pressure plate 22 realizes axial reinforcement and limitation of the handle body 5a.

[0041] like Figure 5 As shown, the test force application module 3 includes a force receiving mechanism 31 and three force applying mechanisms 32. Figure 6 As shown, the force-bearing mechanism 31 includes a cylindrical block 311 and a rectangular block 312. The cylindrical block 311 is used to connect to the tool mounting portion 5b, and the top surface of the right end of the rectangular block 312 is connected to the bottom of the cylindrical block 311. The structures of the three force-applying mechanisms 32 are basically the same, and are all fixed in the housing 1. They are respectively used to apply pressure to the bottom surface of the right end, the left end of the long side side, and the short side side of the rectangular block 312, so as to apply axial force, radial force and torsional force to the force-bearing mechanism 31, that is, to test the axial force, radial force and torsional force of the intelligent tool handle 5 to be tested.

[0042] like Figure 7As shown, each force applying mechanism 32 includes a bracket 321, an electric push rod 322 and a contact unit 323. The electric push rod 322 is fixed on the bottom plate 11 vertically or horizontally through the bracket 321, and the telescopic rod of the electric push rod 322 contacts the bottom surface, long side surface or short side surface of the rectangular block through the contact unit 323. The contact unit 323 specifically includes a sleeve 323a, a spring 323b and a pad 323c. A partition 323d is provided in the sleeve 323a, and a sleeve hole is provided on the partition 323d. The telescopic rod of the electric push rod 322 is limited by a screw 334 after passing through the sleeve hole. The pad 323c is fixed on the telescopic rod, and the spring 323b is nested outside the telescopic rod and is located between the partition 323d and the pad 323c. One end of the sleeve 323a is provided with a top column 326 that contacts the rectangular block 312. The force applying mechanism 32 further includes a proximity switch 325, which is disposed on one side of the electric push rod 322, and the sensing end of the proximity switch 325 faces the pad 323c. The proximity switch 325 is placed at the retracted position of the electric push rod 322. At each restart, all the electric push rods 322 are required to be in the retracted state. The proximity switch 325 is used to detect whether the retracted position is in place, and then the electric push rods 322 are uniformly extended from the retracted position.

[0043] like Figure 1 As shown, a control switch is also provided on the front of the outer cover 12, and the control switch is connected to the internal electrical control box 4, and is used to control the electric push rods 322 of the three force applying mechanisms 32. The control switch is specifically divided into a torsion switch, a round button and an emergency stop button. The three torsion switches control the electric push rods 322 that apply force in three directions respectively, and the torsion switch has two positions, which are used to control whether the electric push rods 322 participate in the action. The two round buttons are used to control the stop and start of the electric push rods 322 that participate in the action. The emergency stop button is used in an emergency to cut off the main power supply of the display device.

[0044] During testing of this embodiment, the switch and button on the front panel of the outer cover 12 can be used to test the effect of one of the applied forces individually, the effect of any two applied forces can be tested, and the effect of three applied forces acting together can also be tested.

[0045] In this embodiment, the spring 323b of the force applying mechanism 32 is selected through calculation, and within the effective stroke, the pressure of the spring 323b does not exceed the maximum load force of the electric push rod 322. The electric push rod 322 is extended and retracted at a uniform speed, so the force on the smart tool handle is also uniform and continuous, and this process can be repeated for easy observation and recording.

[0046] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
