Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of optical module processing, in particular to a limiting fixture for optical module processing. Background Art
[0002] The optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include two parts, namely, transmitting and receiving. Simply put, the function of the optical module is to convert electrical signals into optical signals at the transmitting end. After being transmitted through optical fibers, the receiving end converts the optical signals into electrical signals. The optical module is classified according to the packaging form. It is an Ethernet transmission media conversion unit that interchanges short-distance twisted pair electrical signals with long-distance optical signals. It is also called a photoelectric converter in many places. During the production process, the optical module needs to be fixed in position using a jig to facilitate various processing of the optical module and assembly of parts. However, common limit jigs usually use clamping to limit them, but clamping is prone to excessive squeezing, resulting in deformation of the optical module housing. Once the optical module housing is deformed, it will seriously affect the subsequent various processing steps and the assembly of internal parts. For this reason, the present application proposes a limit jig for optical module processing. Utility Model Content

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0018] Depend on Figure 1-4 The utility model includes a base 1, a storage plate 5 is arranged above the base 1, a first hydraulic rod 2 is fixedly installed at the middle position of the top of the base 1 and the middle position of the bottom of the storage plate 5, a fixing plate 6 is fixedly installed on one side of the top of the storage plate 5, a first clamping plate 7 is arranged on one side of the fixing plate 6, through holes are opened at both ends of the side surface of the fixing plate 6, connecting rods 8 are fixedly installed at both ends of the side surface of the first clamping plate 7, the two connecting rods 8 respectively penetrate and are movably inserted into the through holes at both ends of the fixing plate 6, and a connecting plate 9 is fixedly installed at one end of the two connecting rods 8 away from the first clamping plate 7, a first spring 10 is fixedly connected on the two connecting rods 8 and between the connecting plate 9 and the fixing plate 6, a notch 11 is opened at the middle position of another part of the top of the storage plate 5, An L-shaped moving block 12 is movably installed in the slot 11, the vertical part of the moving block 12 is inserted in the slot 11, the horizontal part of the moving block 12 is located at the top of the storage plate 5, and a slot 13 is opened at one end of the horizontal part of the moving block 12, a telescopic tube 14 is movably inserted in the slot 13, and a second clamping plate 15 is fixedly installed at one end of the telescopic tube 14 extending out of the slot 13, the second clamping plate 15 is parallel to the first clamping plate 7, and the second clamping plate 15 corresponds to the middle position of the first clamping plate 7, and the second hydraulic rod 18 is controlled to push the moving block 12 to move in the slot 11 on the storage plate 5, so that the horizontal part of the moving block 12 can push the telescopic tube 14 and the second clamping plate 15 to approach the first clamping plate 7, so that the optical module housing can be clamped between the first clamping plate 7 and the second clamping plate 15.
[0019] At the same time, the slot 13 and the telescopic tube 14 are both configured as square column structures, and an insertion rod 16 is fixedly installed at the inner end of the slot 13, and the insertion rod 16 is movably inserted in the telescopic tube 14, and a second spring 17 connecting the telescopic tube 14 and the inner wall of the slot 13 is sleeved on the insertion rod 16. When the first clamp 7 and the second clamp 15 clamp the optical module, the second clamp 15 is squeezed to push the telescopic tube 14 to move in the slot 13 along the direction of the insertion rod 16 and squeeze the second spring 17. When the first clamp 7 is squeezed, the connecting rods 8 at both ends of the first clamp 7 will move in the two through holes on the fixed plate 6 and push the connecting plate 9, thereby stretching the two first springs 10 between the connecting plate 9 and the fixed plate 6. In this way, under the action of the first spring 17 and the two second springs 10, the first clamp 7 and the second clamp 15 will not squeeze the optical module housing too hard.

By controlling the second hydraulic rod 18, the moving block 12 can be pushed to move its position in the slot 11 on the storage plate 5.
[0022] In addition, positioning tubes 3 are fixedly installed at the four corners of the top of the base 1, and positioning rods 4 are fixedly installed at the four corners of the bottom of the storage board 5. The bottom ends of the four positioning rods 4 are movably inserted in the corresponding positioning tubes 3. Through the cooperation of the positioning tubes 3 and the positioning rods 4, the first hydraulic rod 2 can push the storage board 5 up and down more stably, so that the position height of the storage board 5 can be adjusted at will, which is convenient for the staff to adjust the storage board 5 to a position height suitable for their work.
[0023] In addition, the bottoms of the first clamping plate 7 and the second clamping plate 15 are not in contact with the top of the storage plate 5 , so that the first clamping plate 7 and the second clamping plate 15 can be smoothly moved on the storage plate 5 .
