[0033] Embodiment 1

[0034] Refer Figures 1 to 6 As shown, this embodiment discloses a specific implementation of an internal thread secondary thread tapping device for a lifting platform.

[0035] Internal thread secondary thread tapping device for a lifting platform, refer Figures 1 to 6As shown, the device includes a bracket 1, a tapping assembly 2, an X-axis module 3, and parallel first Y-axis modules 4 and second Y-axis modules 5. The tapping assembly 2 moves along the X-axis module 3, and the two ends of the X-axis module 3 move along the first Y-axis module 4 and the second Y-axis module 5, respectively. The bracket 1 includes an X-axis square tube 14, a first Y-axis square tube 15, and a second Y-axis square tube 16, which together form a rectangular frame. The first Y-axis module 4 is positioned above the first Y-axis square tube 15, and the second Y-axis module 5 is positioned above the second Y-axis square tube 16. Control lines pass through the interiors of the X-axis square tube 14, the first Y-axis square tube 15, and the second Y-axis square tube 16. The signal control lines of the Y-axis module 4 and the second Y-axis module 5 are all located inside the X-axis square tube 14, the first Y-axis square tube 15, and the second Y-axis square tube 16, and are not exposed. A plurality of parallel support tubes 11 are provided in the middle of the bracket 1. A first positioning plate 12 and a second positioning plate 13 are installed below the support tubes 11 and are staggered. The first positioning plate 12 is provided with a first positioning hole 121, and the second positioning plate 13 is provided with a second positioning hole 131. A lifting platform 6 with a plurality of laser holes 61 is placed above the support tubes 11. A first positioning post 7 passes through the first laser hole 611 and the first positioning hole 121 on the surface of the lifting platform 6, and a second positioning post 8 passes through the second laser hole 612 and the second positioning hole 131 on the surface of the lifting platform 6.

[0036] Specifically, see Figures 1 to 6 Each laser hole 61 on the surface of the lifting platform 6 has an internal thread to fix batteries or other workpieces of different sizes through different laser holes 61. After the lifting platform 6 is painted, paint adheres to the internal thread surface of its laser holes 61, affecting subsequent use. The purpose of this embodiment is to accurately position the lifting platform 1 to be tapped a second time through the first positioning hole 121 and the second positioning hole 131, and then drive the tapping assembly 2 to tap each laser hole 61 a second time according to the preset coordinates under the drive of the X-axis module 3, the parallel first Y-axis module 4 and the second Y-axis module 5, so as to remove the paint or foreign matter on the internal thread surface of the laser hole 61. This embodiment achieves the characteristics of high efficiency, high precision positioning and automated secondary tapping of each laser hole.

[0037] See Figure 1The lifting platform 6 includes a horizontal section 62 and a bending section 63. A plurality of laser holes 61 are distributed in an array or discrete manner on the horizontal section 62. These laser holes 61 are formed by laser cutting and have the characteristic of accurate positioning. Since the lifting platform 6 in this embodiment has a bending section 63, due to insufficient bending precision, bending errors may exist at different positions on the vertical surface of the bending section 63. If two adjacent bending sections 63 are used as a reference for positioning the lifting platform 6, there is a high possibility of inaccurate positioning of the lifting platform 6. Therefore, this embodiment uses a first positioning hole 121 and a second positioning hole 131 to accurately position the lifting platform 1 to be tapped a second time. The specific principle is as follows: The first positioning plate 12 has a first waist hole 122 and a second waist hole 123 at both ends. One end of the first positioning plate 12 is fastened to the first support tube 111 by a first screw and the first waist hole 122, and the other end of the first positioning plate 12 is fastened to the second support tube 112 by a second screw and the second waist hole 123; the second positioning plate 13 has a first waist hole 122 and a second waist hole 123 at both ends. The third waist hole 132 and the fourth waist hole 133 are used to fasten one end of the second positioning plate 13 to the third support tube 113 via a third screw and the third waist hole 132, and to fasten the other end of the second positioning plate 133 to the fourth support tube 114 via a fourth screw and the fourth waist hole 132; the width of the first waist hole 122 is slightly larger than the outer diameter of the first screw, the width of the second waist hole 123 is slightly larger than the outer diameter of the second screw, and the width of the third waist hole 132 is slightly larger than the outer diameter of the third screw. The width of the fourth waist hole 132 is slightly larger than the outer diameter of the fourth screw; by adjusting the installation positions of the first waist hole 122, the second waist hole 123, the third waist hole 132 and the fourth waist hole 133 in the Y-axis direction, the positions of the first positioning hole 121 and the second positioning hole 131 in the Y-axis direction can be finely adjusted; by finely adjusting the installation positions of the first waist hole 122, the second waist hole 123, the third waist hole 132 and the fourth waist hole 133 in the X-axis direction, the positions of the first positioning hole 121 and the second positioning hole 131 in the X-axis direction can be finely adjusted.

[0038] See Figure 2 and Figure 3The working principle of the tapping assembly 2 is as follows: The tapping assembly 2 includes a base 21, a cylinder 22, a tapping motor 23, and a tapping head 24. The base 21 moves along the X-axis module 3. A vertical slide rail 211 is provided on the base 21. The tapping motor 23 is mounted on a slide 25, which is gantry-shaped. The vertical part of the slide 25 moves up and down along the slide rail 211. The telescopic part 221 of the cylinder 22 drives the slide 25 to rise and fall. The telescopic part 221 faces upwards, allowing the cylinder 22 to be compactly mounted on the rear side of the base 21. A first magnetic switch 222 is positioned near the top of the cylinder 22, determining the origin position of the cylinder 22. A second magnetic switch 223 and a third magnetic switch 224 are positioned near the bottom of the cylinder 22, at different heights, providing two stroke limits for the cylinder 22. Each stroke limit corresponds to a different specification. Tapping operation; several laser holes 61 are formed by laser cutting. During the cutting process, the coordinate position of each hole is determined by coordinates. Each laser hole 61 has accurate coordinates. The X-axis module 3, the parallel first Y-axis module 4, and the second Y-axis module 5 drive the tapping assembly 2 to perform secondary tapping on each laser hole 61 one by one, based on the coordinates of each laser hole 61, in order to remove paint or foreign matter from the inner thread surface of the laser hole 61. This embodiment achieves the characteristics of high efficiency, high precision positioning, and automated secondary tapping of each laser hole. To limit the movement range of the tapping assembly 2 and the X-axis module 3, position sensors are respectively set at both ends of the X-axis module 3 and at both ends of the first Y-axis module 4. To ensure the accuracy of the secondary tapping of the tapping head 24, the tapping head 24 is a quick-change torque overload tapping chuck. If the tapping head 24 is not aligned with the laser hole 61 and the tapping is not completed within the set time, the time relay controls the tapping assembly 2 to stop working to protect the tapping assembly 2.

[0039] See Figures 1 to 6 The adjacent support tubes 11 are hollowed out. The first support tube 111, the second support tube 112, the third support tube 113 and the fourth support tube 114 are all round tubes. The waste generated by the secondary tapping falls directly into the waste tray 17 set at the bottom of the bracket 1, which avoids the accumulation of waste between the lifting platform 6 and the support tubes 11.
