[0003] The existing machine tool turntable structure has the following main disadvantages during use: the turntable will cause a decrease in rotation accuracy during long-term use, so it is necessary to manually calibrate the turntable's rotation accuracy and radial runout regularly, which is troublesome, time-consuming and labor-intensive. Therefore, there is room for improvement. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0021] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0022] Example 1:

[0023] Combine Figure 1-3 As shown, this embodiment provides a turntable structure for a machining center, including: a main body mechanism 100 and a runout detection mechanism 200 .

[0024] Among them, the main mechanism includes a base 110, a turntable body 120 rotatably installed on the top of the base 110, a bracket 130 fixed on one side of the base 110, a rotating shaft 140 rotatably installed on the bracket 130, a pulley 150 fixed on the top of the rotating shaft 140, an angle sensor 160 installed on one side of the base 110 and fixedly connected to the bottom end of the rotating shaft 140, a transmission belt 170 with one end sleeved on the turntable body 120 and the other end sleeved on the pulley 150, and a first alarm light 180 fixed on the top of the bracket 130.

[0025] The base 110 is used to install the turntable body 120 to ensure the stability of the turntable body 120 during rotation. The turntable body 120 is used to fix the workpiece and drive the workpiece to rotate, so as to facilitate processing at different positions of the workpiece.

[0026] One end of the bracket 130 is fixed to the base 110, and a bearing 131 is provided at the other end of the bracket 130. The outer ring of the bearing 131 is fixed to the bracket 130, and the inner ring is fixed to the outer side surface of the rotating shaft 140 to ensure the stability of the rotating shaft 140 during rotation. The rotating shaft 140 is used to install the pulley 150. At the same time, the angle sensor 160 is fixed to the bottom end of the rotating shaft 140, so that when the pulley 150 drives the rotating shaft 140 to rotate, the angle sensor 160 can monitor the rotation angle of the rotating shaft 140 in real time.

[0027] An annular groove 121 is provided on the outer surface of the turntable body 120, and one end of the transmission belt 170 is embedded in the annular groove 121, so that when the turntable body 120 rotates, the pulley 150 can be driven to rotate synchronously. In addition, the transmission ratio of the turntable body 120 and the pulley 150 is 1:6, that is, when the turntable body 120 rotates 60 degrees, the pulley 150 rotates 360 degrees.

[0028] The first alarm light 180 is used to start when the rotation angle of the turntable body 120 detected by the angle sensor 160 does not match the set rotation angle of the turntable body 120, to alarm the user, so that the user can maintain the turntable body 120 in time.

[0029] The vibration detection mechanism 200 is used to monitor the vibration amplitude of the turntable body 120 in real time, including a support rod 210 fixed on the other side of the base 110, a cylinder 220 fixed on the support rod 210, a probe rod 230 with one end slidingly arranged in the inner cavity of the cylinder 220 and the other end extending out and close to the outer side surface of the turntable body 120, a laser ranging sensor 240 installed on one side of the cylinder 220 and extending into the inner cavity of the cylinder 220, and a second alarm light 250 fixed at the end of the support rod 210.

[0030] The support rod 210 is used to fix the cylinder 220 to ensure the stability of the cylinder 220. The cylinder 220 is used to install the probe rod 230 and the laser ranging sensor 240. The probe rod 230 includes a movable block 231 movably arranged in the inner cavity of the cylinder 220, a detection rod 232 with one end fixed on the movable block 231 and the other end extending out of the cylinder 220 and close to the outer side of the turntable body 120, and a spring 233 connecting the movable block 231 and the inner bottom wall of the cylinder 220. The movable block 231 is used to install the detection rod 232. The end of the detection rod 232 is close to the outer surface of the turntable body 120, so that when the rotating body jumps, it can drive the calibration rod to move. The spring 233 is used to make the end of the monitoring rod close to the surface of the turntable body 120.

[0031] The laser distance measuring sensor 240 is used to monitor the moving distance of the probe rod 230. When the jumping distance of the probe rod 230 is greater than the set value, the second alarm light 250 is activated to alarm the user.

[0032] The working principle and usage process of the present invention are as follows: when the rotating body rotates, the pulley 150 is driven to rotate by the transmission belt 170, and the rotation of the pulley 150 drives the rotating shaft 140 to rotate. At this time, the angle sensor 160 monitors the rotation angle of the rotating shaft 140 in real time. When the detected rotation angle is inconsistent with the rotation angle set by the turntable body 120, it is judged that the rotation accuracy of the turntable body 120 has decreased, and the first alarm light 180 is started to alarm the user. In addition, when the rotating body rotates, the end of the probe rod 230 is always close to the outer surface of the turntable body 120. When the turntable produces radial runout, it drives the probe rod 230 to move. At this time, the laser ranging sensor 240 monitors the runout distance of the probe rod 230. When the runout distance of the probe rod 230 is greater than the set value, the second alarm light 250 is started to alarm the user.

[0033] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
