[0039] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] like Figures 1 to 9 As shown, the profile cutting positioning wedge self-locking mechanism includes a first positioning component 10 and a second positioning component 20.

[0041] The first positioning component 10 includes a lower base plate 11 and an upper base plate 13, and a connecting bracket 12 is provided between the lower base plate 11 and the upper base plate 13.

[0042] The lower base plate 11 has a positioning side plate 18 on its left side, with a side plate opening 181 on the side plate 18. The lower base plate 11 has a positioning grid 17 on its right side. The upper surface of the lower base plate 11 has a guide ramp 14 at the front, with a guide ramp 141 at the top. The upper surface of the lower base plate 11 has a mounting base 15 at the rear, with a plurality of pushing units 16 on the mounting base 15. Each pushing unit 16 includes a pushing cylinder 161 and a wedge-shaped pushing block 162. The pushing cylinder 161 drives the pushing block 162, which cooperates with the guide ramp 14.

[0043] It should be noted that the top planes of the positioning side plate 18 and the positioning grid 17 are at the same height.

[0044] The upper base plate 13 is provided with an upper pressure cylinder 19, and the output shaft of the upper pressure cylinder 19 is provided with an upper pressure block 191.

[0045] The second positioning component 20 includes a cutting substrate 21, which is disposed on the left side of the positioning side plate 18. The cutting substrate 21 is parallel to the positioning side plate 18 and the positioning grid 17.

[0046] The cutting base plate 21 has a slit 211 through which the saw blade S passes. The cutting base plate 21 also has a lateral return unit 22, which includes a lateral return cylinder 222. A pressure block 223 is provided on the output shaft of the lateral return cylinder 222. The lateral return unit 22 also includes a cylinder mounting base 221, on which the lateral return cylinder 222 is mounted.

[0047] In addition, a V-groove 212 is provided on the side wall of the cutting substrate 21, which is used to avoid the pressure block 223.

[0048] In addition, the size of the pressure block 223 is adapted to the side plate opening 181. The pressure block 223 can extend beyond the side plate opening 181.

[0049] like Figure 7 and Figure 8 As shown, the output shaft of the push cylinder 161 is provided with a connecting hook 1611, and the rear of the push block 162 is provided with a rear hook connecting groove 1622, which engages with the connecting hook 1611. The bottom of the push block 162 is provided with a sliding inclined surface 1621, which cooperates with the guide inclined surface 141. The top of the push block 162 is provided with a mounting protrusion 1623, which is provided with a separable top pad 163, and the top pad 163 is provided with a separable rib pad 164. It should be noted that the top pad 163 and the rib pad 164 can be customized according to the profile.

[0050] It should be noted that top pad 163 and stiffener pad 164 do not necessarily have to be present at the same time. If profile M has a relatively thin wall thickness, it is best to use stiffener pad 164.

[0051] like Figure 10 As shown, profile M includes surface A M1, surface B M2, surface C M3, rib A M4, and inner surface B M5.

[0052] The working principle of the positioning wedge self-locking mechanism for this profile cutting is explained below, with the following steps:

[0053] Step 1, as follows Figure 11 and Figure 12 As shown, the robotic arm delivers four profiles M to the upper part of the pushing unit 16, causing the profiles M to fall onto the corresponding top pad 163 and rib pad 164. At this time, the B-side M2 ​​of the four profiles M is lower than the top of the positioning grid 17. Simultaneously, the pushing cylinder 161 of the pushing unit 16 is in a retracted state, the lateral return cylinder 222 of the lateral return unit 22 is also in a retracted state, and the upper pressure cylinder 19 is also in a retracted state.

[0054] Step 2, as follows Figure 13 and Figure 14 As shown, the upper cylinder body 19 extends and the upper pressure block 191 moves downward until the upper pressure block 191 abuts against the top plane of the positioning side plate 18 and the positioning grid 17 to form an upper reference surface;

[0055] Step 3, as follows Figure 15 and Figure 16As shown, the lateral return cylinder 222 extends, the pressure block 223 passes over the V-groove 212 and the side plate opening 181, and abuts against the profile M, causing the four profiles M to abut against the inner wall of the positioning grid 17. It should be noted that at this time, there is a gap P between the upper surface of the profile M and the lower surface of the upper pressure block 191;

[0056] Step 4, as follows Figures 17 to 20 As shown, the pushing cylinder 161 of the pushing unit 1 extends, and the pushing block 162 moves upward along the guide slope 141 of the guide inclined block 14 until the pushing block 162 presses the four profiles M against the upper reference surface. At this time, the rib pad block 164 presses against the A rib M4, and the top pad block 163 presses against the inner B surface M5. Then, the cutting machine is started, and the saw blade S of the cutting machine passes through the slit 211 and cuts the four profiles M in one go.

[0057] Step 5: After the cutting is completed, the saw blade S is reset, the upper pressure cylinder 19 retracts and resets, the lateral return cylinder 222 retracts and resets, the downstream robot arm takes away the four cut profiles M, and then the push cylinder 161 retracts and resets.

[0058] Step 6: Repeat steps 1 to 5.

[0059] The following provides further explanation of step 4.

[0060] During the extension of the pushing cylinder 161 of the pushing unit 1, the connecting hook 1611 of the pushing cylinder 161 continuously applies a horizontal leftward thrust. Simultaneously, the connecting hook 1611 slides downward in the rear hook connecting slot 1622 of the pushing block 162, causing the pushing block 162 to continuously rise until it reaches its highest point. At this point, the guide ramp 14 and the pushing block 162 form an interlocking structure. That is, even if the pushing block 162 is subjected to significant downward pressure, it will not slide down. Furthermore, even if the pushing cylinder 161 fluctuates, this fluctuation will not be transmitted to the upper pushing block 162, ensuring stability and reliability.

[0061] It should be noted that during operation, even if the top pad block 163 and the rib pad block 164 are worn, the push block 162 can automatically compensate for the wear by relying on the inclined sliding structure between the push block 162 and the guide inclined block 14, which greatly extends the service life of the top pad block 163 and the rib pad block 164.

[0062] The wedge-shaped self-locking mechanism for profile cutting transforms the direct top-mounting method in existing technology into a bevel-fitting top-mounting method. By utilizing the self-locking characteristic of the bevel, it greatly improves the reliability and stability of profile fixing and effectively enhances the accuracy of profile cutting.

[0063] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
