Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-4 The present invention provides a technical solution: a special bolt hole processing tool for a spring clamp for a garage door, comprising a base plate 1, two sets of processing components are arranged above the base plate 1, the processing components are respectively arranged on both sides of the base plate 1, and an installation component is arranged in the middle of the base plate 1. The spring clamp is clamped by the installation component, and then the bolt hole is processed by the processing component. The quality of the spring clamp is judged when processing the bolt hole.

[0033] The processing assembly includes a side plate 2, a driving motor 20 and a slide rail 4. The side plate 2 is fixed on the base plate 1. A cylinder 6 is fixed on the side of the side plate 2 away from the mounting assembly. The slide rail 4 is fixed on the base plate 1. A sliding plate 3 is slidably connected to the slide rail 4. A connecting plate is fixed on one side of the sliding plate 3. A mounting plate 19 is fixed on the top of the connecting plate. A mounting seat 7 is fixed on the sliding plate 3. The output end of the cylinder 6 is fixedly connected to the mounting plate 19. Starting the cylinder 6 can push the mounting plate 19 to move, thereby driving the sliding plate 3 to move on the slide rail 4 through the connecting plate.

[0034] A threaded drill bit 9 is fixed at the output end of the drive motor 20. The drive motor 20 is fixed inside the mounting seat 7. The drive motor 20 is fixedly connected to the mounting plate 19. When the sliding plate 3 moves, it pushes the drive motor 20 to move. The drive motor 20 starts and drives the threaded drill bit 9 to process the spring chuck.

[0035] The installation assembly includes a bearing plate 5, on which four groups of slide rails 18 are fixed, and each group of slide rails 18 is slidably connected with a push plate 16, and a mobile drive is provided at the sliding connection between the slide rails 18 and the push plate 16, and a mounting frame 8 is fixed on the push plate 16, and a plug rod 10 is threadedly connected to the mounting frame 8, and a limit plate 17 is fixed to the end of the plug rod 10, and the limit plate 17 is in contact with the inner wall of the spring clamp, and a pressure sensor (not shown in the figure) is fixed on one side of the limit plate 17. When the spring clamp needs to be installed, the spring clamp is placed on the bearing plate 5, and the mobile drive is started to control the push plate 16 to move on the slide rails 18, so that the limit plate 17 is in contact with the inner wall of the spring clamp to support and position the spring clamp.

[0036] A connecting seat 13 is fixed in the middle of the bearing plate 5, and cameras 11 are fixed on both sides of the connecting seat 13. The cameras 11 are used to take pictures of the inner wall and the drilled hole of the spring clamp. A limiting block 12 is arranged on the top of the connecting seat 13, and a long groove 15 is opened in the middle of the limiting block 12. A positioning rod 14 is arranged inside the long groove 15. The top of the positioning rod 14 is arranged as a threaded structure, and a nut is arranged on the threaded structure of the positioning rod 14. The side of the limiting block 12 close to the spring clamp is arranged as a stepped shape, and the stepped shape of the limiting block 12 matches the edge of the spring clamp. When the spring clamp is positioned, the limiting block 12 is controlled to move on the connecting seat 13 so that the stepped shape on one side of the limiting block 12 contacts the edge of the spring clamp, so as to limit the spring clamp and avoid movement when processing the bolt hole of the spring clamp. When the stepped shape on one side of the limiting block 12 contacts the edge of the spring clamp, the nut is rotated to fix the top of the limiting block 12 connecting seat 13.

[0037] A bolt hole processing tool for a spring clamp for a garage door also includes a bolt hole processing tool detection system. The bolt hole processing tool detection system includes a processing detection module and a logic judgment module. The processing detection module includes an image generation submodule, a pressure receiving submodule and a push control submodule. The image generation submodule is electrically connected to a camera 11, the pressure receiving submodule is electrically connected to a pressure sensor, and the push control submodule is electrically connected to a mobile drive.

[0038] The logic judgment module includes a center judgment submodule, a shape generation submodule and an analysis submodule. The center judgment submodule and the shape generation submodule are electrically connected to the image generation submodule, and the analysis submodule is electrically connected to the pressure receiving submodule.

[0039] The bolt hole processing tooling detection system includes the following specific operation steps:

[0040] Step 1: Place the spring chuck on the bearing plate 5, start the mobile drive to control the push plate 16 to move on the slide rail 18, so that the limit plate 17 contacts the inner wall of the spring chuck to position the spring chuck.

[0041] It should be noted that when tapping on the spring chuck, a reserved hole needs to be opened on the spring chuck to facilitate tapping. When the spring chuck is placed on the bearing plate 5, the reserved hole is aligned with the thread drill 9 to facilitate subsequent tapping.

[0042] Step 2: After the spring chuck is positioned, check whether the position of the reserved hole on the spring chuck is accurate, so as to improve the accuracy of machining the bolt hole;

[0043] Step three: When the position accuracy of the reserved hole is no problem, control the limit block 12 to move on the connecting seat 13 so that the step-shaped side of the limit block 12 contacts the edge of the spring chuck, limiting the spring chuck to prevent it from moving when processing the bolt hole of the spring chuck, and then control the processing assembly to process the bolt hole of the reserved hole, and further judge the quality of the spring chuck when processing the bolt hole.

[0044] Step 2 includes the following specific steps:

[0045] Step 2-a: When the spring chuck is positioned, first determine whether the position of the reserved hole is correct;

[0046] Specifically, the camera 11 takes a photo of the threaded drill bit 9 and the reserved hole and transmits it to the image generation submodule, which transmits the signal to the center judgment submodule, which judges whether the threaded drill bit 9 and the reserved hole are in the same center. If they are not in the same center, the staff needs to rotate the spring chuck to adjust the position of the reserved hole and the threaded drill bit 9. If the reserved hole and the threaded drill bit 9 are still not in the same center after adjustment, it means that the position and size of the reserved hole are not accurate. At this time, the staff removes the spring chuck and manually processes the reserved hole.

[0047] Step 2-b: When the reserved hole is accurately positioned, the limit plate 17 is controlled by the push control submodule to continue pushing the inner wall of the spring clamp to determine the strength of the spring clamp;

[0048] Specifically, one of the limit plates 17 is controlled to push the inner wall of the spring chuck, and a photo is taken by the camera 11 and transmitted to the image generation submodule. Since the normal spring chuck pattern is set in the shape generation submodule, the image generation submodule transmits the signal to the shape generation submodule for comparison with the set normal spring chuck pattern. If they are consistent, it means that the shape of the spring chuck has not changed under the thrust of the limit plate 17. If they are inconsistent, it means that the shape of the spring chuck has changed under the thrust of the limit plate 17.

[0049] It should be noted that after the working detection of one of the limit plates 17 is completed, the next limit plate 17 is controlled to work until the working of the four limit plates 17 is completed.

[0050] Further analysis of the strength of the spring clamp shows that when only one of the limit plates 17 works, the shape of the inner wall of the spring clamp changes, indicating that although the strength of the spring clamp is not very high, it is within the allowable range, indicating that the strength of the spring clamp is medium. When more than two limit plates 17 work, the shape of the inner wall of the spring clamp changes, indicating that the strength of the spring clamp is low. When the degree of deformation of the spring clamp is high, the spring clamp is directly removed.

[0051] When the strength of the spring chuck is medium, it is determined again whether the threaded drill bit 9 and the reserved hole are in the same center. If they are still in the same center, the subsequent bolt hole processing can be carried out. If they are not in the same center, it means that the position of the reserved hole changes when the spring chuck is deformed, and the position of the reserved hole and the threaded drill bit 9 is adjusted again by the staff;

[0052] Through the above steps, the position accuracy of the reserved hole can be ensured while the strength of the spring chuck can be tested, thereby improving the production quality of the spring chuck.

[0053] Step 3 includes the following specific steps:

[0054] Step 3-a: When the processing assembly processes the bolt hole, the pressure of the limit plate 17 near the reserved hole position on the inner wall of the spring chuck is detected in real time by the pressure sensor;

[0055] Specifically, when the threaded drill bit 9 processes the reserved hole, the pressure sensor on the limit plate 17 close to the position of the reserved hole detects the pressure of the limit plate 17 on the inner wall of the spring chuck in real time, and transmits the pressure to the pressure receiving submodule. Since the pressure of the limit plate 17 on the inner wall of the spring chuck previously recorded in the analysis submodule is A, the real-time detected pressure of the limit plate 17 on the inner wall of the spring chuck is B. The pressure receiving submodule transmits the real-time detected pressure signal to the analysis submodule. Through the analysis of the analysis submodule, when B is equal to A, it means that the inner wall of the spring chuck has not changed during the processing of the reserved hole, and when B is equal to A, it means that the inner wall of the spring chuck has changed during the processing of the reserved hole.

[0056] Step 3-b: After the bolt hole is processed, the pressure of the limit plate 17 on the inner wall of the spring chuck is determined again to analyze the quality of the spring chuck after the bolt hole is processed.

[0057] Specifically, after the processing is stopped, the pressure sensor detects the pressure change of the limit plate 17 on the spring chuck again. If the pressure returns to A, it means that the quality of the spring chuck is high. If the pressure does not return to A after the processing is stopped, it means that the spring chuck has been affected by the external force of the processing and has not returned to its original state. The inner wall of the spring chuck still exerts pressure on the limit plate 17, indicating that there is a problem with the rigidity of the spring chuck and the quality is poor.

[0058] Through the above steps, after the bolt hole of the spring chuck is processed, the quality of the spring chuck can be further judged by judging the pressure change of the inner wall of the spring chuck on the limit plate 17, thereby improving the yield rate.

[0059] The present invention can judge the overall quality of the spring chuck before and after the spring chuck processes the bolt hole, thereby improving the yield and quality of the spring chuck processing the bolt hole.
