Description

Technical Field

[0001] The utility model relates to the technical field of coil spring threading, in particular to a coil spring threading device. Background Art

[0002] Planar scroll springs are usually wound in the form of spiral scrolls into a disc shape, so they are also called coil springs. To this day, the installation of coil springs is often achieved using traditional tools and methods. Since the elastic coefficient of the coil spring is relatively high and the force-bearing area of ​​the outer end is small, workers can only use tools such as screwdrivers to press down the outer end, which is inconvenient to operate. In addition, workers need to accurately apply a large amount of pressure to the outer end of the coil spring during operation. If the external force is removed or slipping occurs due to insufficient strength or inaccurate force application position when pressing down the outer end, it is easy to cause the coil spring to bounce, collapse, and other adverse situations.

[0003] Therefore, this traditional installation method is not only time-consuming and labor-intensive, but also inefficient and, more importantly, unsafe. Utility Model Content

[0009] The displacement of the lever is limited by the length of the slide slot.

[0010] Preferably, a mounting groove is provided on the annular inner wall of the fixing ring, and a bearing is provided in the mounting groove, and the inner ring of the bearing is sleeved and fixed to the outer wall of the fixing cylinder.

[0011] The fixing ring forms a rotational fit with the fixing cylinder through the bearing, so that the fixing cylinder can rotate freely.

[0012] Preferably, connecting rods distributed at equal distances are fixed to the tops of the outer walls around the fixed tube, and a swivel is fixed to one end of the connecting rod away from the fixed tube.

[0013] By rotating the swivel, the swivel drives the fixed cylinder to rotate through the connecting rod, so that the fixed cylinder can be rotated conveniently.

[0014] Preferably, a through hole is opened at the top center of the bottom shell, and the inner diameter of the through hole is matched with the outer diameter of the bottom block.

[0015] The bottom block can pass through the through hole and move up and down on the bottom shell.

[0016] Preferably, a through opening is provided on the top of the bottom shell and one side of the annular outer wall, and the width of the through opening is greater than the width of the clamping block and the push rod motor.

[0017] On the one hand, the through hole facilitates one end of the coil spring to enter the bottom shell and connect with the clamping block, and on the other hand, the bottom block moves upward to drive the push rod motor and the clamping block to pass through the through hole upward, so that the coil spring and the clamping block are separated from each other.

[0018] The beneficial effects of the utility model are:

[0027] A sliding groove is provided on one side outer wall of the fixed cylinder 5, and the lever 7 forms a sliding fit with the sliding groove. The displacement of the lever 7 is limited by the length of the sliding groove. A mounting groove is provided on the annular inner wall of the fixed ring 3. A bearing is provided in the mounting groove. The inner ring of the bearing is sleeved and fixed with the outer wall of the fixed cylinder 5. The fixed ring 3 forms a rotational fit with the fixed cylinder 5 through the bearing, so that the fixed cylinder 5 can rotate freely.

[0028] Connecting rods 9 distributed at equal distances are fixed to the top of the outer walls around the fixed cylinder 5, and a swivel 10 is fixed to the end of the connecting rod 9 away from the fixed cylinder 5. By rotating the swivel 10, the swivel 10 drives the fixed cylinder 5 to rotate through the connecting rod 9, which is convenient for rotating the fixed cylinder 5. A through hole is opened at the center of the top of the bottom shell 1, and the inner diameter of the through hole is adapted to the outer diameter of the bottom block 11. The bottom block 11 can pass through the through hole to move up and down in the bottom shell 1. A through hole 14 is opened on the top of the bottom shell 1 and one side of the annular outer wall. The width of the through hole 14 is greater than the width of the clamping block 13 and the push rod motor 12. On the one hand, the through hole 14 facilitates one end of the disc spring to enter the bottom shell 1 and connect with the clamping block 13. On the other hand, the bottom block 11 moves upward to drive the push rod motor 12 and the clamping block 13 to pass through the through hole 11 upward, thereby separating the disc spring and the clamping block 13 from each other.

[0029] Working principle:

[0030] During operation, the bottom shell 1 is covered to the installation position of the coil spring, and then one end of the coil spring is passed through the through-port 14 and clamped with the opening on the clamping block 13. By rotating the rotating wheel 10, the rotating ring 10 drives the fixed cylinder 5 to rotate through the connecting rod 9, and the fixed cylinder 5 drives the movable rod 6 to rotate through the shifting rod 7. The movable rod 6 drives the coil spring to be wound and installed through the bottom block 11, the push rod motor 12 and the clamping block 13. After the installation is completed, the push rod motor 12 and the clamping block 13 are rotated to the bottom of the through-port 14, and the shifting rod 7 is pushed upward, and the bottom block 11, the push rod motor 12 and the clamping block 13 are driven by the movable rod 6 to move upward. Under the obstruction of the bottom shell 1, the wound coil spring and the clamping block 13 are separated from each other.
