Description

Technical Field

[0001] This invention relates to the field of glass machining technology, and more specifically to a method for manufacturing a glass stacking rotating frame. Background Technology

[0002] Glass stacker cranes are indispensable core automated equipment in glass deep processing production lines, mainly used for the continuous automatic stacking and handling of glass sheets. As a key component of the glass stacker crane, the glass stacking rotating frame is not only the core component realizing the rotation function after the stacker connects the sheets, but also plays a crucial role in fixing the hinge support of the tilting frame and the tilting cylinder. Its production quality directly affects the stability of glass rotation and stacking accuracy. The position and elevation of the rotating frame wheels are directly determined by the groove limiters. The tilting frame hinge point is mounted on the mounting plate of the rotating frame; the tilting cylinder hinge point is fixed to the ear plate of the rotating frame.

[0003] The main performance indicators of the rotating frame are as follows: the parallelism between the bottom of the rotating wheel axle mounting groove and the center line of the hinge point hole of the tilting cylinder and the mounting surface of the tilting frame hinge support is ≤0.1mm; the flatness of the plane formed by the bottom of the four rotating wheel axle mounting grooves is ≤0.03mm; the width error of the mounting groove is ≤0.1mm; and the relative concentricity of the mounting holes on both sides of the mounting groove is ≤0.2mm.

[0004] See Figure 1 , Figure 2 , Figure 3 The production process of a conventional glass stacking and rotating frame is as follows: Step 1, Material Preparation: Prepare fixed-length rectangular tubes, flip hinge support mounting plate 101, flip cylinder mounting ear plate 301, wheel axle mounting plate 1200 blank, wheel axle mounting plate 1200, rotation center fixing plate 701, rotation drive connecting plate 201, reinforcing rib plate one 102, and reinforcing rib plate two 202; it should be noted that for the outer side that can be machined by CNC, the wheel axle mounting plate 1200 blank can be directly welded; for the inner side that cannot be machined by CNC, the wheel axle mounting plate 1200 is fitted and welded. The wheel axle mounting plate 1200 is a precision-machined finished product. The second step is to mark and position each rectangular tube on a horizontal welding platform, and complete the welding of the rectangular tubes of the rotating frame to form each rectangular tube. The third step involves marking and positioning the flip hinge support mounting plate 101, reinforcing rib plate 102 and rotation center fixing plate 701 on the upper surface of the welding frame. Step 4: Hoist the tilting and stacking rotating frame, and weld the tilting cylinder mounting ear plate 301, the rotating drive connecting plate 201, the reinforcing rib plate 202, and the wheel axle mounting plate blanks on both sides of the stacking rotating frame. Step 5: CNC gantry precision machining of the tilting hinge support mounting plate 101, tilting cylinder mounting ear plate 301, rotation center fixing plate 701, rotation drive connecting plate 201, two outer wheel axle mounting grooves 1201 and two inner rectangular tube wheel axle mounting notches 1001, and making the tilting cylinder mounting ear plate 301 form the tilting cylinder mounting hinge point 01 and the rotation center fixing plate 701 form the frame rotation center 02. Step 6: Position the stacking and rotating frame with the mandrel and place two rectangular tube wheel axle mounting notches 1001 on the inside, and weld the wheel axle mounting plate 1200. The problem with conventional methods is: (1) Manual welding, marking, positioning, and mid-way hoisting and turning operations are cumbersome, resulting in low production efficiency and high manufacturing costs; (2) When machining the wheel axle mounting groove 1201 on the outside of the rotating frame of the CNC gantry, it is necessary to first vertically mill the rectangular tube and the wheel axle mounting plate 1200, and then replace the side milling head to mill the mounting hole on the wheel axle mounting plate 1200, which results in the CNC gantry machine tool occupying a long time and the processing cost being high. (3) CNC gantry side milling requires the use of a side milling head. When machining the mounting plate sideways, it is necessary to ensure that there is enough space to accommodate the side milling head. However, the inner space is insufficient, which restricts the position of the wheel axle mounting groove 1201 inside the stacking rotating frame. It is impossible to use the outer wheel axle mounting groove 1201 machining method, which means that the rectangular tube wheel axle mounting notch 1001 needs to be machined by CNC and then the wheel axle mounting plate 1200 needs to be welded. When welding the wheel axle mounting plate 1200 inside the stacking rotating frame, the mandrel is difficult to ensure that the wheel axle mounting plate 1200 is symmetrical with respect to the center line of the rectangular tube, and the operation is inconvenient. It is easy to cause the wheel axle mounting plate 1200 to be misaligned during welding, which in turn causes the wheel axle to interfere with the rectangular tube or mounting plate and cannot be assembled. (4) During the welding of wheel axle mounting plate 1200, the end notch is prone to shrinkage and deformation due to welding, making it difficult to remove the positioning mandrel, resulting in low production efficiency. Moreover, the mandrel needs to be manually fixed during welding. Summary of the Invention

Weld the rectangular tube and the wheel axle mounting plate 1200. In this embodiment, the auxiliary positioning fixture 1300 provides support for the wheel axle mounting notch 1001 to prevent deformation during welding, and provides positioning and support for the wheel axle mounting plate 1200. See Figure 14The auxiliary positioning fixture 1300 includes a main body 1301, a positioning block 1302, a reset spring 1303, an expansion core 1304, an expansion core push rod 1305, a bidirectional stud 1306, a clamping block 1307, and a limit screw 1311. The main body 1301 has a U-shaped structure, including a vertical section and a horizontal section. A core expansion rod 1305 is rotatably connected to the center of the horizontal section of the main body 1301. The core expansion rod 1305 is screwed onto a core expansion rod 1304, which is in sliding fit with the bottom of the main body 1301. A groove adapted to the core expansion rod 1304 is provided at the bottom of the main body 1301. Two vertical sections are fixedly connected to the top of the horizontal section, and are symmetrically arranged about the horizontal section. A double-acting stud 1306 is rotatably connected to the middle of each vertical section. Two symmetrically arranged clamping blocks 1307 are slidably connected to each vertical section about its centerline. The clamping blocks 1307 are threadedly connected to the double-acting studs 1306. (See reference...) Figure 15 , Figure 16 A sliding groove 1312 adapted to the clamping block 1307 is provided on the vertical section. In order to prevent the clamping block 1307 from coming out of the sliding groove 1312, a limiting screw 1311 extending into the sliding groove is fixedly connected to the top of the vertical section. A limiting groove 1313 adapted to the limiting screw 1311 is provided on the top of the clamping block 1307. The side of the horizontal segment is coplanar with the side of the vertical segment and forms a limiting surface 1308. The front end of the horizontal segment forms a positioning surface A 1309, and the bottom of the horizontal segment forms a positioning surface B 1310. Two positioning blocks 1302 are slidably connected at the bottom of the horizontal section. The positioning block 1302 is provided with another inclined surface that matches the inclined surface on the expansion core 1304. The vertical movement of the expansion core 1304 is converted into the horizontal movement of the positioning block 1302 at the bottom of the horizontal section through the inclined surface. See Figure 20 , Figure 22 In this embodiment, a wheel axle mounting plate 1200 is provided with a wheel axle mounting groove 1201.

Positioning surface A 1309 is in contact with the vertical surface of wheel axle mounting notch 1001, and positioning surface B 1310 is in contact with the bottom plane of wheel axle mounting notch 1001. Use a socket wrench to screw the expansion core push rod 1305 downwards. The expansion core 1304 moves down and drives the positioning block 1302 to tighten and clamp the inner wall of the rectangular tube of part five 1000. 2) Install the wheel axle mounting plate 1200 onto one side of the main body 1301. Manually adjust the position so that the wheel axle mounting groove 1201 fits against the clamp limiting surface 1308, positioning surface A 1309, and positioning surface B 1310. Use an open-end wrench to rotate the double-ended stud 1306. The threaded rotation will drive the clamping block 1307 to clamp the wheel axle mounting notch 1001 and wheel axle mounting groove 1201 on the clamping part five 1000. Position the remaining wheel axle mounting plates 1200 in the same way as above. 3) After confirming that the positions of each component are correct, use CO2 gas shielded welding to fix the wheel axle mounting plate 1200 and part 5 1000.

[0028] After welding is completed, use a wrench to rotate the bidirectional stud 1306 and the expansion core push rod 1305 in the opposite direction to remove the clamping block 1307 and the expansion core 1304 respectively. The positioning block 1302 is reset under the action of the return spring 1303, and the auxiliary positioning fixture 1300 is removed.
