[0002] In the production of precision electronic products, some component products are assembled by transferring die-cut parts and double-sided adhesive parts. The assembled products also need to be pressed and pressure-maintained to ensure the pulling force of the double-sided adhesive.

[0003] The existing method of assembling precision tubular housings is to manually assemble the parts and perform press-fitting and pressure-maintaining operations, which is very inconvenient; therefore, it does not meet the existing needs. In this regard, we propose a pressure-maintaining fixture for assembling precision tubular housings. Utility Model Content

[0004] The purpose of the utility model is to provide a pressure-maintaining jig for assembling a precision tubular housing, so as to solve the problem that the precision tubular housing assembly method proposed in the above background technology is to manually assemble the parts and perform the pressing and pressure-maintaining operation, which is very inconvenient.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model cooperates with the push rod and the lifting block so that when the device is in use, the arc-shaped screen with glue on it can be first placed on the surface of the lifting block, and then the tubular shell is sleeved on the surface of the cylindrical load-bearing rod. At this time, the screen and the lifting block are inside the tubular shell, and then the first cylinder drives the connecting plate to be pulled back, so that the connecting plate drives the two push rods to move out from the inside of the tubular shell. At this time, the push rod no longer exerts pressure on the L-shaped rod, and the L-shaped rod will pop up due to the elastic potential energy of the compression spring and be stuck at the position of the inclined surface of the push rod surface. At this time, the screen fits the surface of the tubular shell. After the screen is bonded to the tubular shell by glue, the first cylinder drives the connecting plate to push outward, so that the push rod squeezes the L-shaped rod, and then the L-shaped rod drives the lifting block to descend. At this time, the screen and the tubular shell will not follow the lifting block to descend due to the bonding of the glue, and then the tubular shell can be removed from the surface of the cylindrical load-bearing rod, thereby realizing the automatic assembly of the tubular shell and the screen and reducing manpower operation.

[0012] 2. The utility model cooperates with the clamping claws and the lifting cylinder. When the screen is bonded to the tubular shell by glue, the second cylinder can drive the third cylinder to drive the lifting cylinder to move to the position of the clamping claws. At this time, the lifting cylinder is started to drive the clamping plate to descend and open the clamping claws. Then, the lifting cylinder is pushed outward by the third cylinder, so that the lifting cylinder drives the clamping claws to move to the position of the screen. Then, the clamping plate is retracted by the lifting cylinder to close the clamping claws and clamp the position of the screen, thereby maintaining the pressure of the tubular shell and the screen and preventing the screen from separating from the tubular shell.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 6 The utility model provides an embodiment: a pressure-maintaining jig for assembling a precision tubular shell, comprising a jig base 1, a fixed plate 2 is fixedly installed on the top of the jig base 1, two cylindrical bearing rods are provided on the outer surface of the fixed plate 2, a tubular shell 3 is movably installed on the outer surface of the cylindrical bearing rods, a lifting groove 13 is provided inside the tubular shell 3, an L-shaped rod 9 is slidably installed inside the lifting groove 13, a lifting block 8 is fixedly installed on the top of the L-shaped rod 9, a push rod 6 is slidably installed on one side of the L-shaped rod 9, a slope 11 is provided on the bottom end surface of the push rod 6, and two compression springs 10 are provided on one side of the bottom end of the lifting block 8.

[0022] A movable groove 14 is provided inside the tubular shell 3, and the push rod 6 is slidably inserted into the movable groove 14. A positioning rod 12 is fixedly installed inside the lifting groove 13. A positioning groove 16 is provided on the bottom end surface of the L-shaped rod 9, and the positioning rod 12 is slidably inserted into the positioning groove 16. The bottom end of the compression spring 10 is movably connected to the inner surface of the tubular shell 3.

[0023] Through the cooperation of the push rod 6 and the lifting block 8, when the device is in use, the curved screen with glue on it can be placed on the surface of the lifting block 8 first, and then the tubular shell 3 can be sleeved on the surface of the cylindrical bearing rod. At this time, the screen and the lifting block 8 are inside the tubular shell 3, and then the first cylinder 4 drives the connecting plate 5 to pull back, so that the connecting plate 5 drives the two push rods 6 to move out of the inside of the tubular shell 3. At this time, the push rod 6 no longer exerts pressure on the L-shaped rod 9, and the L-shaped rod 9 will pop up due to the elastic potential energy of the compression spring 10. When the push rod 6 is stuck at the inclined surface 11, the screen fits the surface of the tubular shell 3. After the screen is bonded to the tubular shell 3 by glue, the first cylinder 4 drives the connecting plate 5 to push outward, so that the push rod 6 squeezes the L-shaped rod 9, and then the L-shaped rod 9 drives the lifting block 8 to descend. At this time, the screen and the tubular shell 3 will not descend with the lifting block 8 due to the adhesion of glue, and then the tubular shell 3 can be removed from the surface of the cylindrical load-bearing rod, thereby realizing the automatic assembly of the tubular shell 3 and the screen and reducing manual operation.

[0024] A connecting plate 5 is fixedly mounted on the rear side of the two push rods 6 . A first cylinder 4 is disposed on the rear side of the connecting plate 5 . An output end of the first cylinder 4 is fixedly connected to one side of the connecting plate 5 .

[0025] The outer surface of the tubular shell 3 is movably mounted with a clamping jaw 7, and a lifting cylinder 15 is provided on the outer side of the clamping jaw 7. A clamping plate is fixedly mounted on the output end of the lifting cylinder 15, and the clamping plate is fitted with the outer surface of the clamping jaw 7. A third cylinder 18 is provided on the rear side of the lifting cylinder 15, and the output end of the third cylinder 18 is fixedly connected to one end of the lifting cylinder 15.

[0026] Through the cooperation of the clamping claw 7 and the lifting cylinder 15, when the screen is bonded to the tubular shell 3 by glue, the third cylinder 18 can be driven by the second cylinder 17 to drive the lifting cylinder 15 to move to the position of the clamping claw 7. At this time, the lifting cylinder 15 is started, so that the lifting cylinder 15 drives the clamping plate to descend and open the clamping claw 7. Then, the lifting cylinder 15 is pushed outward by the third cylinder 18, so that the lifting cylinder 15 drives the clamping claw 7 to move to the position of the screen. Then, the clamping plate is retracted by the lifting cylinder 15, so that the clamping claw 7 is closed and the position of the screen is clamped, thereby achieving pressure maintenance of the tubular shell 3 and the screen, and avoiding the screen and the tubular shell 3 from separating.

[0027] A track 19 is fixedly installed on the top of the fixture base 1, and the third cylinder 18 is slidably installed on the surface of the track 19. The second cylinder 17 is fixedly installed on both sides of the track 19, and the output end of the second cylinder 17 is fixedly connected to one side surface of the third cylinder 18.

[0028] When the pressure-maintaining jig for assembling a precision tubular housing is used, the curved screen with glue on it is first placed on the surface of the lifting block 8, and then the tubular housing 3 is sleeved on the surface of the cylindrical bearing rod. At this time, the screen and the lifting block 8 are inside the tubular housing 3, and then the first cylinder 4 drives the connecting plate 5 to pull back, so that the connecting plate 5 drives the two push rods 6 to move out of the tubular housing 3. At this time, the push rod 6 no longer applies pressure to the L-shaped rod 9, and the L-shaped rod 9 will pop up due to the elastic potential energy of the compression spring 10 and get stuck at the position of the inclined surface 11 on the surface of the push rod 6. At this time, the screen fits the surface of the tubular housing 3;

[0029] When the screen is bonded to the tubular shell 3 by glue, the third cylinder 18 can be driven by the second cylinder 17 to drive the lifting cylinder 15 to move to the position of the clamping claw 7. At this time, the lifting cylinder 15 is started, so that the lifting cylinder 15 drives the clamping plate to descend and the clamping claw 7 is opened. Then, the lifting cylinder 15 is pushed outward by the third cylinder 18, so that the lifting cylinder 15 drives the clamping claw 7 to move to the position of the screen. Then, the clamping plate is retracted by the lifting cylinder 15, so that the clamping claw 7 is closed and the position of the screen is clamped, thereby achieving pressure maintenance of the tubular shell 3 and the screen to prevent the screen and the tubular shell 3 from being separated.

[0030] After the screen is bonded to the tubular shell 3 by glue, the second cylinder 17 and the third cylinder 18 are started, so that the third cylinder 18 pulls the lifting cylinder 15 back to the origin, and the second cylinder 17 pulls the third cylinder 18 back to the origin position, and then the first cylinder 4 drives the connecting plate 5 to push outward, so that the pushing rod 6 squeezes the L-shaped rod 9, and then the L-shaped rod 9 drives the lifting block 8 to descend. At this time, the screen and the tubular shell 3 will not descend with the lifting block 8 due to the adhesion of glue, and then the tubular shell 3 can be removed from the surface of the cylindrical load-bearing rod, thereby realizing the automatic assembly of the tubular shell 3 and the screen and reducing manual operation.
