Description

Technical Field

[0001] The present invention relates to the technical field of bulb fixtures, and specifically to a flexible spherical bulb processing fixture. Background Art

[0002] During the production and processing of spherical bulbs, fixtures are required to position and clamp the spherical bulbs for processing. For example, the invention patent with the Chinese patent publication number: CN112357578A provides a bulb fixture for lighting equipment, including a mounting plate and several groups of clamping mechanisms distributed on the mounting plate. There is a mounting hole in the middle of the mounting plate for mounting on a mobile tooling. The clamping mechanism includes a clamping seat and clamping arms distributed at the lower end of the clamping seat. The push cylinder controls the telescopic adjustment of the output shaft to drive the lifting of the adapter plate. The adapter plate controls the sliding of the slider through a connecting rod. When the adapter plate descends, the connecting rod descends and pushes the slider to extend. The slider is fixedly connected to the clamping arm, causing the clamping arm to open. When the adapter plate ascends, the connecting rod ascends and pulls the slider to move, and the slider drives the clamping arm to clamp and fix the bulb. This device clamps the lower arc surface of the bulb through a clamping pad, with stable clamping. By sliding and contracting the clamping arm, the impact on the bulb is small, avoiding damage.

[0003] In the above bulb fixture, although it is convenient to clamp and fix the bulb through the setting of mechanisms such as the clamping mechanism, in actual use, we found that it still has certain deficiencies. For example:

[0004] When the above bulb fixture clamps the bulb, there is no limiting effect, and the bulb is prone to sliding up or down. If you want to prevent the bulb from sliding, you must increase the clamping force. However, if the clamping force is too large, it is easy to damage the bulb, resulting in the bulb bursting.

[0005] Based on this, we propose a flexible spherical bulb processing fixture. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION Embodiment 1

[0034] Please refer to Figures 1 - 5 , a flexible spherical bulb processing fixture, including a positioning cylinder 1 with a placement opening at the top, as Figures 2 - 5 shown, and further provided with:

[0035] The first moving ring 3 is vertically movably arranged in the first annular cavity 2 opened in the upper part of the wall of the positioning cylinder 1, and its inner side is connected to the top end of the first annular sleeve 4, and the bottom end of the first annular sleeve 4 is fixedly arranged on the inner wall of the positioning cylinder 1;

[0036] The second moving ring 6 is vertically movably arranged in the second annular cavity 5 opened in the middle part of the wall of the positioning cylinder 1, and its inner side is connected to the top end of the second annular sleeve 7, and the bottom end of the second annular sleeve 7 is fixedly arranged on the inner wall of the positioning cylinder 1;

[0037] In this embodiment, both the first annular sleeve 4 and the second annular sleeve 7 are made of elastic rubber material;

[0038] By controlling the downward movement of the first moving ring 3 and the second moving ring 6, the middle parts of the first annular sleeve 4 and the second annular sleeve 7 can be respectively bulged, as Figure 3 shown.

[0039] When the first annular sleeve 4 and the second annular sleeve 7 bulge, they respectively clamp the upper and lower sides of the most convex part of the spherical bulb, so that the position of the spherical bulb can be clamped and fixed. Not only the fixing effect is good, and the spherical bulb can be prevented from detaching from the positioning cylinder 1, but also because both the first annular sleeve 4 and the second annular sleeve 7 are made of elastic rubber material, the clamping is softer and the spherical bulb is not easily damaged. In addition, this positioning method does not affect the rotation of the spherical bulb.

[0040] In this embodiment, the first moving ring 3 and the second moving ring 6 are connected by a connecting rod 8, and a first spring 9 is also sleeved on the connecting rod 8. The first spring 9 is fixedly arranged between the bottom of the first moving ring 3 and the inner bottom wall of the first annular cavity 2;

[0041] And a bottom rod 10 is fixedly installed at the bottom of the second moving ring 6. The bottom end of the bottom rod 10 extends to the outside of the positioning cylinder 1. By pulling the bottom rod 10, the second moving ring 6 can be moved downward. When the second moving ring 6 moves downward through the connecting rod 8, the first moving ring 3 can be driven to move downward, and at the same time, the first spring 9 is compressed;

[0042] After the bottom rod 10 is released, under the elastic force of the first spring 9, the first moving ring 3 will move upward to return to its original position, and then drive the second moving ring 6 to move upward to return to its original position through the connecting rod 8.

[0043] In order to further ensure the return ability of the second moving ring 6, in this embodiment, a second spring 11 is also sleeved on the bottom rod 10. The second spring 11 is fixedly arranged between the bottom of the second moving ring 6 and the inner bottom wall of the second annular cavity 5;

[0044] Thus, when the second moving ring 6 moves downward, the second spring 11 will be compressed, and later, it will also return to its original position under the elastic force of the second spring 11. Embodiment 2

[0045] Please refer to Figure 6 , on the basis of Embodiment 1, in this embodiment, the bottom end of the bottom rod 10 is fixedly installed on the driving ring 12, and the driving ring 12 is movably arranged up and down below the positioning cylinder 1;

[0046] Thus, by controlling the downward movement of the driving ring 12, the bottom rod 10 can be pulled downward.

[0047] As Figure 2 and Figure 6 shown, a bottom cylinder 16 is fixedly installed at the bottom of the positioning cylinder 1. A lead screw 15 is rotatably arranged in the bottom cylinder 16. A nut 14 is threadedly connected to the outer wall of the lead screw 15. The nut 14 is fixedly connected to the driving ring 12 through a connecting plate 13. In addition, a moving groove for the movement of the connecting plate 13 is formed in the outer wall of the bottom cylinder 16;

[0048] The rotation of the lead screw 15 can make the nut 14 threadedly connected to its outer wall move up and down. The up and down movement of the nut 14 can drive the driving ring 12 to move up and down through the connecting plate 13.

[0049] As Figure 6 shown, the bottom end of the lead screw 15 extends to the outside of the bottom cylinder 16 and is fixedly connected to a wrench head 18. By means of the wrench head 18, the rotation of the lead screw 15 can be controlled.

[0050] As Figure 6 shown, the top end of the lead screw 15 extends to the outside of the bottom cylinder 16 and is fixedly connected to a support plate 17. An anti-slip pad is arranged on the top of the support plate 17 for increasing the friction force with the bulb;

[0051] After the spherical bulb is placed in the positioning cylinder 1, its bottom is located on the anti-slip pad of the support plate 17. Due to the large friction force between the two, by rotating the spherical bulb, the support plate 17 and the lead screw 15 can be rotated.
