DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] Refer to Figure 1 , 5 As shown, an embodiment of the present invention provides a core shaft spring elastic force testing device, including a core shaft 114, a support frame 104, a lifting mechanism A101 arranged on the support frame 104, and a detector arranged on the lifting mechanism A101. The lifting mechanism A101 is an electric slide rail, and the lifting mechanism A101 is used to adjust the height of the detector. When the lifting mechanism A101 adjusts the detector to descend, the detector performs component detection on the core shaft 114 below.

[0028] Refer to Figure 5 , 6 As shown, the detector is composed of a device seat 103, a probe switch A112, and two probe switches B113. The probe switch A112 and the probe switch B113 pass through the device seat 103 respectively, and the detection heads of the probe switch A112 and the probe switch B113 are both located at the bottom of the device seat 103. A locking block 116 and an omega spring 115 are provided on the core shaft 114. One end of the omega spring 115 is sleeved on the protruding portion of the locking block 116 to form an elastic component. The probe switch A112 is used to detect the locking block 116. Specifically, when the probe switch A112 contacts the protruding portion on the locking block 116, it indicates that the locking block 116 is installed normally. When the protruding portion on the locking block 116 does not correspond to the position of the probe switch A112, no contact occurs, thereby completing the installation detection of the locking block 116.

[0029] The two probe switches B113 are used to detect the omega spring 115. Specifically, the two probe switches B113 are arranged according to the bending trajectory of the omega spring 115 below, and there is a notch at the end of the probe switch B113, that is, when the omega spring 115 is installed normally, when the probe switch B113 descends, the omega spring 115 is just located in the notch and will not contact the probe switch B113. When the omega spring 115 is installed abnormally and misplaced, the omega spring 115 will contact the probe switch B113, thereby detecting the abnormal installation of the omega spring 115.

[0030] Refer to Figure 1 , 2 As shown in FIGS. 3 and 7 , a clamping tool is provided on the support frame 104, and the clamping tool is used to clamp the mandrel 114 and move the mandrel 114. The clamping tool includes an assembly seat 105, a slide rail 1 201, a bottom plate 202, a cylinder A203, a slide rail 204, an electric slide rail A106, a cylinder B301, a manipulating platform 302, and a mechanical claw 107. The assembly seat 105 is installed with the bottom plate 202 through the slide rail 1 201, and the bottom plate 202 is installed with the support frame 105 through the slide rail 204. 4 installation, the driving end of the cylinder A203 is connected to the rear end of the assembly seat 105, the driving end of the electric slide rail A106 is connected to the bottom plate 202, the cylinder B301 is fixedly installed on the assembly seat 105, and the driving end of the cylinder B301 is connected to the adjustment table 302, the adjustment table 302 is movable and can be lifted and lowered and installed on the assembly seat 105, the mechanical claw 107 is installed on the adjustment table 302, and three spindle tables are provided on the support frame 104, and the spindle tables are provided with spindle grooves for placing the spindle 114;

[0031] A lifting mechanism B is provided on one side of the support frame 104. The lifting mechanism B is installed with the machine tool. The lifting mechanism B is composed of a load-bearing arm 108, a cylinder C109, and an electric slide rail B401. The electric slide rail B401 and the cylinder C109 are installed with the load-bearing arm 108. The driving ends of the electric slide rail B401 and the cylinder C109 are connected with a parts table 110.

[0032] like Figure 4 As shown, a testing mechanism 111 is provided on the parts table 110, and the testing mechanism 111 includes a testing table 6, an electric slide rail C7, and a pressure sensor 8. The telescopic end of the electric slide rail C7 is provided with a pressure sensor 8. A core shaft opening is provided on the surface of the testing table 6, and the testing table 6 is fixedly connected to the parts table 110;

[0033] Specifically, the electric slide rail A106 adjusts the bottom plate 202 to move on the slide rail 204 to the position of the mandrel below the device seat 103. After reaching the position, the cylinder A203 controls the assembly seat 105 to move on the slide rail 1 201 on the bottom plate 202, and then the height of the mechanical claw 107 is adjusted by the cylinder B301 and the manipulator 302. The mechanical claw 107 grabs the mandrel and resets it to place the mandrel 114 on the mandrel table, that is, below the test mechanism 111. The lifting mechanism B adjusts the test mechanism 111 to descend through the part table 110, and the test mechanism 111 detects the elastic force of the mandrel 114.

[0034] The elastic force detection is specifically as follows: when the detection platform 6 descends, the upper end of the core shaft 114 is in the core shaft opening, and the core shaft opening has a fixing effect on the core shaft 114. The telescopic end of the electric slide rail C7 extends, and the pressure sensor 8 acts on the protrusion of the locking block 116 during the extension. The electric slide rail C7 performs three telescopic operations, thereby measuring three feedback force values ​​of the locking block 116, and feeding back the test content to the monitoring platform. After the test is completed, the test mechanism 111 rises, and the base plate 202 moves to the core shaft position under the device seat 103 again. Since the clamping tool includes two mechanical claws 107, it can clamp the core shaft under the device seat 103 and the core shaft under the test mechanism 111 at the same time. When the clamping tool is reset, the core shaft under the device seat 103 can be moved to under the test mechanism 111, and the core shaft under the test mechanism 111 is moved to Figure 1 The mandrel on the rightmost side of the table is finally labeled by the labeler and then loaded into the storage basket.
