Description

Technical Field

[0001] This invention relates to a positioning and fixing device, specifically to a positioning fixture for a belt conveyor support frame. Background Technology

[0002] The belt bed support frame plays a crucial role in preventing belt misalignment and material conveying in color sorters. However, because the overall straightness and inner opening dimensions of the side and middle crossbeams of the belt bed support frame cannot be guaranteed after welding, deviations occur during later assembly and production. To address this issue, previously, two to three people were required to pre-tighten the four corners of the belt bed support frame using welding clamps, then measure the shape and diagonal dimensions with a tape measure, and finally, several people simultaneously tightened the welding clamps. Even then, there was a high probability that tightening would cause changes in the shape and diagonal dimensions of the belt bed support frame, resulting in wasted manpower, time, and irreversible deformation defects. Therefore, a tooling for quick positioning of the belt bed support frame is needed to facilitate actual operation, improve production efficiency, and ensure product quality. Summary of the Invention

[0028] A drive mechanism is provided on the U-shaped frame 1, located between the fixed block 3 and the positioning plate 7, to drive the screw 9 to rotate. The drive mechanism includes a slider 48. A groove 38 is provided between the U-shaped frame 1 and the mounting plate 2, and the slider 48 is installed in the groove 38. A lead screw 39 is provided in the groove 38. One end of the lead screw 39 is fixed to the output shaft of the motor 40, and the other end of the lead screw 39 is connected to the U-shaped frame 1 through a bearing. The lead screw 39 passes through the slider 48 and is threadedly connected to the slider 48. The slider 48 is fixed to the horizontal plate 41. The lower end of the horizontal plate 41 is rotatably connected and fixed to the vertical plate 42. The vertical plate 42 can be connected to the horizontal plate 41 through a rotating shaft or a bearing. A motor 43 is fixed to one end of the vertical plate 42, and a fixing sleeve 44 is provided at the other end of the vertical plate 42. The fixing sleeve 44 is fixed to the output shaft of the motor 43, and an electromagnetic plate 45 is fixed on the inner wall of the fixing sleeve 44. The positioning plate 10 is made of iron.

[0029] Working principle: such as Figure 7As shown, the belt bed support frame consists of two symmetrical side rods 46 and a connecting frame 47. When positioning and clamping the small belt bed support frame is required, the side rods 46 are extended between positioning plate 1 7 and positioning plate 2 10 respectively. Motor 1 40 is started, driving the lead screw 39 to rotate. The lead screw 39 drives the slider 3 48 to move along the slide groove 2 38. When the vertical plate 2 42 moves between positioning plate 2 10 and positioning plate 3 13, the vertical plate 2 42 is rotated so that the fixing sleeve 44 faces away from the positioning plate 3 13. Then, the fixing sleeve 44 is fitted onto the positioning plate 2 10 near the positioning plate 3 13, and the electromagnetic plate 45 is energized to fix the fixing sleeve 44 to the positioning plate 2 10. Motor 2 43 is started, driving the fixing sleeve 44 to rotate. The fixing sleeve 44 drives the screw 2 9 to rotate, while the vertical plate 2 42 gradually approaches the side rod 46 under the action of the slider 3 48 until the positioning plate 2 10 abuts against the outer wall of the side rod 46.

[0030] While operating the drive mechanism, slider 15 can be moved along guide rod 16 and slide groove 14, so that rotating sleeve 22 is fitted onto rotating block 8, spring 31 is in a compressed state, and both ends of compression block 30 are fixed by push block 32 and limiting plate 37 respectively, rotating sleeve 22 and rotating block 8 rotate. At the same time, due to the compression action of spring 31, rotating sleeve 22 drives rotating block 8 and screw 6 to approach side rod 46 until positioning plate 7 abuts against the inner wall of side rod 46. Then slider 36 is moved upward along slide rail 35, so that limiting plate 37 moves out of hollow rod 27, and then limiting plate 37 is rotated so that limiting plate 37 is no longer inserted into hollow rod 27. Rotating handle 2 34 causes screw 33 to rotate, which in turn moves push block 32 downwards. Push block 32 separates the two pressing blocks 30, allowing them to fully enter the hollow rod 27. Spring 31 further compresses, increasing the clamping force of positioning plate 1 7 on the side rod. Thus, positioning plate 1 7 and positioning plate 2 10 are used to quickly position and clamp the small belt bed support frame.

[0031] When positioning and clamping the large belt conveyor support frame is required, the side rods 46 are extended between positioning plate two 10 and positioning plate three 13 respectively. The vertical plate two 42 is moved between positioning plate two 10 and positioning plate one 7, and then the driving mechanism is used to press positioning plate two 10 against the inner wall of the side rod 46. The cylinder 11 is activated, causing positioning plate three 13 to press against the outer wall of the side rod 46, thereby achieving rapid positioning and clamping of the large belt conveyor support frame using positioning plates two 10 and three 13.

[0032] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the present invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
