[0020] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.
[0021] Please refer to Figure 1 , the existing machine tool includes a bed body 10, a Y-direction moving platform 11, a bed body gantry 12, an X-direction moving slide 13 and a Z-axis head 14. The Y-direction moving platform 11 is installed on the bed body 10 and can move along the Y-axis on the bed body 10. The bed body gantry 12 is fixedly installed on the bed body 10. The X-direction moving slide 13 is slidably installed on the bed body gantry 12. The X-direction moving slide 13 can move along the X-axis of the bed body gantry 12. The Z-axis head 14 is slidably installed on the X-direction moving slide 13. The Z-axis head 14 can move along the Z-axis. A machining tool is installed on the Z-axis head 14. Refer to Figure 3 , a string of iron plates and a backrest form a workpiece 30, and holes, bosses, side ribs, etc. on the workpiece 30 are used as positioning points 31.
[0022] See Figure 1 and 2 As shown in FIGS. 54 and 55, on the basis of the existing machine tool, a measuring device 20 is installed on the Z-axis head 14 of the machine tool. The measuring device 20 includes a push rod device 21 and a measuring probe 22. The fixed end of the push rod device 21 is fixedly installed with the Z-axis head 14, and the measuring probe 22 is installed at the telescopic end of the push rod device 21. By installing the measuring device 20 on the Z-axis head 14 of the machine tool, the workpiece 30 can be measured before processing. Moreover, since the measuring probe 22 is installed on the push rod device 21, when the measuring probe 22 is in use, the push rod device 21 extends downward. After the measurement is completed, the push rod device 21 retracts, and the measuring probe 22 does not interfere with subsequent processing.
[0023] Preferably, the measuring probe 22 adopts a PO series trigger probe or a laser displacement measuring sensor.
[0024] Furthermore, see Figure 2 As shown in FIG. 60, a support seat 141 is installed on the Z-axis head 14, and the push rod device 21 is installed on the support seat 141. The support seat 141 includes two triangular ear plates. A connecting plate is provided at the top of the two ear plates. The two ear plates are bolted to the Z-axis head 14. The push rod device 21 is installed on the upper side of the connecting plate, and the telescopic rod of the push rod device 21 passes through the connecting plate downward.
[0025] Furthermore, a slider 23 is fixedly installed on the Z-axis head 14. The slider 23 corresponds to the position of the push rod device 21. A linear slide rail 24 is longitudinally slidably installed on the slider 23. The telescopic end of the push rod device 21 is connected to the linear slide rail 24, and the measuring probe 22 is installed at the lower end of the linear slide rail 24. The linear slide rail 24 moves up and down through the guidance of the slider 23. Since the matching accuracy between the linear slide rail 24 and the slider 23 is high, the stability of the measuring probe 22 when moving up and down is improved. When installing the linear slide rail 24 or the slider 23, an avoidance hole is opened on the support seat 141 as needed to enable the linear slide rail 24 to pass through the support seat 141.
[0026] In one of the solutions, an extended mounting seat 25 is installed at the lower end of the linear slide rail 24. Mounting holes are provided on the mounting seat 25, and the measuring probe 22 is fixedly installed on the mounting seat 25 through the mounting holes. With the above structure, the installation of the measuring probe 22 is facilitated. The mounting holes on the mounting seat 25 are adapted to the mounting rods at the top of the measuring probe 22.
[0027] In one of the solutions, an extension seat 241 is installed on the linear slide rail 24, and a ball eye joint 211 is installed at the telescopic end of the push rod device 21. The ball eye joint 211 is fixedly connected to the extension seat 241 through a screw 242. With the above structure, the connection between the telescopic end of the push rod device 21 and the linear slide rail 24 is facilitated.
[0028] Preferably, the push rod device 21 is a pneumatic cylinder, a hydraulic cylinder or an electric push rod.
[0029] The working principle or operation process of the present utility model is as follows:
[0030] See Figure 1 、 2 , during use, the workpiece 30 composed of the string plate and the back frame is placed on the positioning platform on the Y-direction moving platform 11 and then clamped by the clamping cylinder.
[0031] First, the measuring probe 22 of the measuring device 20 stops at the origin. The Y-direction moving platform 11 drives the moving workpiece 30 to move, and makes the positioning point 31 to be measured move under the measuring probe 22. Then the push rod device 21 extends, the measuring probe 22 moves downwards, and the Y-direction moving platform 11 and the X-direction moving slide 13 cooperate to move, so as to measure the positioning point 31 on one side. After that, the push rod device 21 shortens, the measuring probe 22 moves upwards, the X-direction moving slide 13 drives the measuring device 20 to move to the positioning point 31 on the other side. Then the push rod device 21 extends, the measuring probe 22 moves downwards, and the Y-direction moving platform 11 and the X-direction moving slide 13 cooperate to move, so as to measure the positioning point 31 on the other side. After the measurement is completed, the push rod device 21 shortens, and the measuring probe 22 moves upwards to reset.
