Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts tooling technology, and in particular to a door hinge rubber strip tooling. Background Technology
[0002] In the automotive manufacturing industry, door hinges are a key component that connects car doors to the car body. To ensure the smooth opening and closing of car doors and the overall sealing of the vehicle, rubber strips are usually installed on the edges of door hinges.
[0003] The precision of the adhesive strip's adhesion directly affects the overall performance of the door hinge. If the adhesive strip is misaligned at the hinge, the seal between the hinge and the door will be inadequate, allowing rainwater, dust, and other impurities to easily enter the vehicle. Furthermore, if the adhesive strip is not firmly attached, it is prone to detaching during frequent door opening and closing, requiring frequent replacement or repair. This increases the cost of automobile production and subsequent maintenance, reducing production efficiency and economic benefits. Therefore, the installation position of the adhesive strip needs to be checked after it is adhered to the door hinge.
[0004] In existing technologies, when inspecting the position of the rubber strip on a door hinge, workers usually visually observe whether the edge of the rubber strip is aligned with the preset baseline of the door hinge to determine whether the offset is within the allowable tolerance range. However, the worker's inspection method depends on the experience and skill level of the inspector, which is highly subjective and results in low accuracy, and has obvious shortcomings. Utility Model Content
[0005] To improve the accuracy of testing, this application provides a door hinge rubber strip tooling.
[0006] The door hinge rubber strip tooling provided in this application adopts the following technical solution:
[0007] A door hinge adhesive strip fixture includes a worktable with a positioning component and a fixing component. The positioning component positions a workpiece on the worktable, and the fixing component fixes the workpiece. A detection component is also provided on the worktable, including a laser rangefinder sensor whose laser emission point faces the adhesive strip adhesion point. A control box is provided on the worktable, and the laser rangefinder sensor is electrically connected to the control box via a control system.
[0008] By adopting the above technical solution, when inspecting the rubber strip on the door hinge, the positioning component is first used to place the door hinge workpiece at the inspection position on the workbench. Then, the workpiece is fixed by the fixing component. Finally, the inspector activates the laser rangefinder through the control box. The laser emitted by the laser rangefinder is aimed at the side wall of the rubber strip to measure the distance and transmits the measured distance value to the control system. By comparing the measured value with the preset standard distance, the accuracy of the rubber strip's position can be determined. The entire inspection process does not require the inspector to make subjective judgments by visual inspection, thereby improving the accuracy of the rubber strip installation position detection.
[0009] Optionally, the positioning component includes multiple positioning platforms disposed on the worktable. Each positioning platform is provided with a positioning pin that engages with a through hole on the workpiece. One of the positioning platforms is provided with a support frame that matches the shape of the workpiece. When the workpiece is fitted onto the positioning pin, the support frame supports the workpiece.
[0010] By adopting the above technical solution, when the door hinge workpiece is placed on the workbench, the initial placement position of the workpiece is quickly determined by the insertion and cooperation of the positioning pin and the through hole. At the same time, the support bracket supports the workpiece, improving the stability of the workpiece during the inspection process. The positioning component provides an initial reference for the inspection of the workpiece, reducing the possibility of inaccurate inspection results due to the initial position offset of the workpiece, thereby further improving the accuracy of the rubber strip installation position detection.
[0011] Optionally, the fixing assembly includes multiple fixing frames disposed on the worktable, each fixing frame having a top support block at one end, a connecting frame rotatably connected to the fixing frame, a clamping block at one end of the connecting frame and a drive rod hinged to the other end, and a cylinder disposed on the fixing frame, the piston rod of the cylinder being connected to the drive rod.
[0012] By adopting the above technical solution, after the door hinge positioning is completed, the cylinder is activated, the cylinder drives the drive rod to move, the drive rod drives the connecting frame to rotate around the fixed frame, the connecting frame drives the clamping block to approach the top support block and presses and fixes the workpiece on the top support block. In this way, the door hinge workpiece is fixed on the worktable, effectively reducing the possibility of displacement or shaking of the workpiece due to external force during the inspection process, ensuring that the inspection position of the workpiece remains stable, thereby further improving the accuracy of the rubber strip installation position detection.
[0013] Optionally, the detection assembly further includes a support shaft vertically mounted on the workbench. A mounting shaft is detachably connected to the support shaft via a connector. The mounting shaft is perpendicular to the support shaft. The connector is a bidirectional bolt clamp, which includes an integrally formed first bolt clamp and a second bolt clamp. The first bolt clamp is fitted onto the outer surface of the support shaft, and the second bolt clamp is fitted onto the outer surface of the mounting shaft. The clamp axes of the first bolt clamp and the second bolt clamp are perpendicularly arranged in opposite planes.
[0014] By adopting the above technical solution, during the inspection process, the worker adjusts the height of the mounting shaft on the support shaft by loosening the first bolt clamp, and then loosens the second bolt clamp, allowing the mounting shaft to slide in a direction perpendicular to the support shaft. This adjusts the relative distance between the laser rangefinder and the workpiece in the horizontal direction. The position of the laser sensor can be changed through bidirectional adjustment, so that the laser emission direction can be directed to the rubber strip at different positions on the workpiece. This improves the adaptability of the inspection component, allowing the inspector to adjust the position of the laser rangefinder according to actual needs.
[0015] Optionally, the laser rangefinder is detachably connected to the end of the mounting shaft via a third bolt clamp.
[0016] By adopting the above technical solution, when the laser rangefinder sensor malfunctions, workers can quickly replace it using the third clamp bolt. At this time, there is no need to maintain or replace the entire detection component, thus reducing the maintenance cost of the detection component.
[0017] Optionally, a protective cover is provided on the outer surface of the mounting shaft, and the protective cover covers the outer surface of the laser rangefinder.
[0018] By adopting the above technical solution, the protective cover can protect the laser rangefinder from interference and damage from the external environment, and extend the service life of the detection components.
[0019] Optionally, the worktable has a sliding groove along its length, and a lateral adjustment component is provided inside the sliding groove. The lateral adjustment component includes a lead screw rotatably connected in the sliding groove, a movable seat threadedly connected to the lead screw, the movable seat slidably connected in the sliding groove, a mounting shaft disposed on the movable seat, and a handwheel coaxially disposed at the end of the lead screw extending out of the sliding groove.
[0020] By adopting the above technical solution, when it is necessary to adjust the lateral position of the laser rangefinder, the inspector rotates the lead screw, which drives the moving seat to slide along the sliding groove, thereby driving the laser rangefinder on the mounting shaft to move synchronously. This further facilitates the inspection of the adhesive strips at different positions on the workpiece and further improves the applicability of the inspection component.
[0021] Optionally, a mounting plate is provided at the bottom of the mounting shaft, and the mounting plate is detachably connected to the movable base by a plurality of connecting bolts.
[0022] By adopting the above technical solution, when the testing component needs to be replaced or maintained, workers can separate the testing component from the moving base by disassembling and assembling the connecting bolts.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. This application uses a laser rangefinder sensor to measure the distance between the laser emitted by the sensor and the side wall of the rubber strip. The measured distance is then transmitted to the control system. By comparing the measured value with a preset standard distance, the accuracy of the rubber strip's position can be determined. The entire detection process does not require the inspector to make subjective judgments with the naked eye, thereby improving the accuracy of the rubber strip installation position detection.
[0025] 2. This application sets up a positioning component and a fixing component. The positioning component positions the workpiece at the initial detection position, and then the clamping block clamps and fixes the workpiece on the top support block. This effectively reduces the possibility of displacement or shaking of the workpiece due to external force during the detection process, ensuring that the detection position of the workpiece remains stable, thereby further improving the accuracy of the detection of the rubber strip installation position.
[0026] 3. This application sets up a connector, and the position of the laser sensor can be changed through the bidirectional adjustment of the connector. This allows the laser emission direction to be directed at the adhesive strip at different positions on the workpiece, improving the adaptability of the detection component and enabling the inspection personnel to adjust the position of the laser rangefinder sensor according to actual needs.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] This application discloses a door hinge adhesive strip tooling.
[0034] Example 1
[0035] Reference Figure 1 A door hinge rubber strip tooling includes a workbench 1, on which a control box 2 is fixedly installed. The control box 2 integrates a control system, and during the testing process, the testing personnel control the operation through the control box 2.
[0036] Reference Figure 1 and Figure 2 The workbench 1 is provided with a positioning component 3, a fixing component 4 and a detection component 5. The positioning component 3 includes a plurality of positioning platforms 31 fixedly installed on the workbench 1. In this embodiment, there are two positioning platforms 31, which are spaced apart along the length of the workbench 1. Each positioning platform 31 is fixedly connected with a positioning pin 32 that is inserted into a through hole on the workpiece. A support frame 33 matching the shape of the workpiece is fixedly connected on the workbench 1 near the detection component 5. The support frame 33 is L-shaped. When the workpiece is sleeved on the positioning pin 32, the support frame 33 supports the workpiece.
[0037] When inspecting the rubber strip on the door hinge, the inspector aligns the through hole on the workpiece with the positioning pin 32 and inserts it. The initial placement position of the workpiece is determined by the insertion and cooperation between the positioning pin 32 and the through hole. At the same time, the support bracket 33 supports the workpiece, providing an initial reference for the inspection of the workpiece and reducing the possibility of inaccurate inspection results due to the initial position deviation of the workpiece.
[0038] Reference Figure 1 and Figure 2The fixing component 4 includes a plurality of fixing frames 41 fixedly installed on the workbench 1. In this embodiment, there are two fixing frames 41, which are respectively set on one side of the two positioning platforms 31. Each fixing frame 41 is fixedly connected to a top support block 42 at its end.
[0039] Reference Figure 1 and Figure 2 A connecting frame 43 is rotatably connected to the center of the fixed frame 41. A clamping block 44 for clamping the workpiece is fixedly connected to one end of the connecting frame 43 near the top support block 42, and a drive rod 45 is hinged to the other end. In this embodiment, both the top support block 42 and the clamping block 44 are wedge-shaped blocks adapted to the shape of the workpiece. A cylinder 46 is installed on the fixed frame 41. The piston rod of the cylinder 46 is connected to the drive rod 45 to drive the connecting rod to move in the horizontal direction.
[0040] After the door hinge is positioned, cylinder 46 is activated, which drives drive rod 45 to move. Drive rod 45 pushes connecting frame 43 to rotate around fixed frame 41. Connecting frame 43 drives clamping block 44 to move closer to top support block 42 and clamps the workpiece onto top support block 42. The clamping block 44 applies pressure to the workpiece to fix the door hinge workpiece, effectively reducing the possibility of displacement or shaking of the workpiece due to external force during the inspection process, and ensuring that the workpiece remains stable during subsequent inspection.
[0041] Reference Figure 1 and Figure 3 The detection component 5 includes a support shaft 51 fixedly connected to the workbench 1. The support shaft 51 is vertically arranged, and a mounting shaft 53 is detachably connected to the support shaft 51 via a connector 52. The mounting shaft 53 is perpendicular to the support shaft 51, and the connector 52 is a two-way bolt clamp.
[0042] Reference Figure 1 and Figure 3 The bidirectional bolt clamp includes an integrally formed first bolt clamp 521 and second bolt clamp 522. The clamp axes of the first bolt clamp 521 and the second bolt clamp 522 are arranged perpendicularly to each other. The first bolt clamp 521 is sleeved on the outer surface of the support shaft 51. When the first bolt clamp 521 is loosened, the mounting shaft 53 can slide along the length direction of the support shaft 51. The second bolt clamp 522 is sleeved on the outer surface of the mounting shaft 53. When the second bolt clamp 522 is loosened, the mounting shaft 53 can slide along its own axis.
[0043] Reference Figure 1 and Figure 3 A laser rangefinder sensor 55 is detachably connected to the end of the mounting shaft 53 near the workpiece via a third bolt clamp 54. The laser emission position of the laser rangefinder sensor 55 faces the adhesive strip of the workpiece. The laser rangefinder sensor 55 is electrically connected to the control box 2 via the control system.
[0044] After the workpiece is fixed, the worker loosens the first bolt clamp 521 and slides the mounting shaft 53, thereby changing the height of the laser range sensor 55 on the support shaft 51. Then, the worker loosens the second bolt clamp 522, and the mounting shaft 53 can slide in a direction perpendicular to the support shaft 51, thereby adjusting the relative distance between the laser range sensor 55 and the workpiece in the horizontal direction. When the laser emission direction of the laser range sensor 55 is adjusted to face the side wall of the rubber strip to be tested, the worker tightens the first bolt clamp 521 and the second bolt clamp 522 to fix it.
[0045] After the installation is completed, the inspector activates the laser rangefinder 55 through the control box 2. The laser emitted by the laser rangefinder 55 is aimed at the side wall of the rubber strip to measure the distance and transmits the measured distance value to the control system. By comparing the measured value with the preset standard distance, the position of the rubber strip is judged to be accurate. The entire inspection process does not require the inspector to make subjective judgments by the naked eye, thereby improving the accuracy of the rubber strip installation position detection.
[0046] Reference Figure 1 and Figure 3 A protective cover 6 is fixedly connected to the outer surface of the mounting shaft 53. The protective cover 6 is U-shaped and covers the outer surface of the laser rangefinder 55. The protective cover 6 protects the laser rangefinder 55 from interference and damage from the external environment and extends the service life of the detection component 5.
[0047] The implementation principle of the door hinge rubber strip tooling in this application embodiment is as follows: When inspecting the rubber strip on the door hinge, the positioning function of the positioning component 3 is first used to place the door hinge workpiece at the inspection position of the workbench 1. Then, the workpiece is fixed by the fixing component 4. Finally, the inspector activates the laser range sensor 55 through the control box 2. The laser emitted by the laser range sensor 55 is aimed at the side wall of the rubber strip to measure the distance and transmits the measured distance value to the control system. By comparing the measured value with the preset standard distance, it is determined whether the position of the rubber strip is accurate. The entire inspection process does not require the inspector to make subjective judgments by the naked eye, thereby improving the accuracy of the rubber strip installation position detection.
[0048] Example 2
[0049] Reference Figure 4 The difference between this embodiment and Embodiment 1 is that the workbench 1 has a sliding groove 7 along its length, and a lateral adjustment component 8 is provided inside the sliding groove 7.
[0050] Reference Figure 4The lateral adjustment component 8 includes a lead screw 81 rotatably connected in a sliding groove 7. The end of the lead screw 81 extends out of the sliding groove 7 and is coaxially fixedly connected to a handwheel 82. A movable seat 83 is threadedly connected to the lead screw 81. The movable seat 83 is slidably connected in the sliding groove 7. Both the movable seat 83 and the sliding groove 7 have T-shaped cross sections.
[0051] Reference Figure 4 The mounting shaft 53 is fixedly connected to the bottom of the mounting plate 9. The mounting plate 9 is detachably connected to the movable seat 83 by multiple connecting bolts 10. In this embodiment, there are four connecting bolts 10. When the detection component 5 needs to be replaced or maintained, the worker can separate and install the detection component 5 from the movable seat 83 by loosening or tightening the connecting bolts 10.
[0052] The implementation principle of Example 2 is as follows: When it is necessary to adjust the lateral position of the laser rangefinder 55, the inspector rotates the lead screw 81, which drives the moving seat 83 to slide along the sliding groove 7, thereby driving the laser rangefinder 55 on the mounting shaft 53 to move synchronously, thus further facilitating the detection of the adhesive strips at different positions on the workpiece and further improving the applicability of the detection component 5.
[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
