Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a novel testing device for bolt washers. Background Technology

[0002] Bolt washers are a type of accessory frequently used during the installation of automotive engine housings. They are used to secure the engine housing to other parts, ensuring stability for normal engine operation. To ensure a tight fit between the bolt washers and other parts during use, each bolt washer must be calibrated and tested before leaving the factory.

[0003] The bolt washer includes a washer body, arc-shaped grooves on both sides of the washer body, and two mounting holes on the washer body. The basic parameters of the washer body include: the length L1 of the washer body, the width L2 of the washer body, the curvature of the arc-shaped grooves, and the diameter and position of the mounting holes.

[0004] The most common testing method at present is manual measurement, which involves staff using prescribed measuring instruments to measure and statistically analyze various basic parameters. Manual measurement not only has a certain range of errors, but also has a high time cost and low work efficiency. Utility Model Content

[0005] To improve the efficiency of bolt washer inspection, this application provides a novel bolt washer inspection device.

[0006] This application provides a novel bolt washer detection device, which adopts the following technical solution:

[0007] A novel bolt washer detection device includes a frame, a sampling component, and a detection component. The frame includes a top plate, a back plate, and a side plate. Two symmetrical sliding grooves are provided at the bottom of the top plate. The sampling component is disposed on the sliding grooves. The detection component is disposed below the frame. The back plate is disposed on one side of the top plate along the length of the sliding grooves. The side plate is disposed on one side of the top plate along the direction perpendicular to the length of the sliding grooves.

[0008] The detection assembly includes a detection platform, an arc detection component, an aperture detection component, a drive motor, and a limiting plate. The arc detection component includes two strip-shaped protrusions symmetrically arranged on the detection platform. The aperture detection component includes two circular limiting lines symmetrically arranged on the detection platform and located between the two strip-shaped protrusions. Two sets of diameter scale lines are vertically arranged within the circular limiting lines. The limiting plate is located on the side of the detection platform away from the back plate and is rotatably connected to the detection platform. The drive motor is located on the detection platform, and the drive end of the drive motor is fixedly connected to one end of the limiting plate. The length of the strip-shaped protrusions is the same as the specified width of the bolt washer, and the distance between the two strip-shaped protrusions near the outer edge of the detection platform is the same as the length of the bolt washer.

[0009] When testing bolt washers using the above technical solution, the operator first inverts the bolt washer on the testing table and places the arc groove of the bolt washer upside down on the strip protrusion. If the arc groove and the two strip protrusions can fit seamlessly, it proves that the arc is compliant and the length is compliant. If they cannot fit seamlessly, it proves that the product is unqualified.

[0010] Once the curvature and length are within specifications, the drive motor will rotate the limit plate along the edge of the testing platform. When the limit plate rotates to a position above the testing platform and perpendicular to it, one end of the bolt washer should be in close contact with the limit plate. The operator will then observe the positional relationship between the bolt washer and the strip-shaped protrusion. If the end of the bolt washer away from the limit plate is aligned with the edge of the strip-shaped protrusion, the width of the bolt washer is within specifications. If it is not aligned, it is a defective product.

[0011] Once the curvature, length, and width meet the requirements, the operator observes the circular limit line and scale line vertically downwards through the mounting hole of the bolt washer. If the bolt washer significantly obstructs the circular limit line, it indicates that the mounting hole is incorrectly positioned. If it does not significantly obstruct the circular limit line, the operator needs to observe whether the scales on the two mutually perpendicular scale lines are the same. If the scales are the same and match the specified hole diameter, the bolt washer is considered a qualified product. The entire process requires no measuring instruments from the operator; all measurements are performed through direct observation, greatly improving the efficiency of bolt washer inspection.

[0012] Optionally, the detection assembly further includes a rejection component, which is a rejection cylinder disposed on the back plate and used to reject detected defective products.

[0013] By adopting the above technical solution, after a defective product is detected, the rejection cylinder pushes the defective bolt pad from one side of the back plate forward, thus pushing it away from the inspection table. This further improves the work efficiency of the operators and also enhances the recycling efficiency of defective products.

[0014] Optionally, the detection assembly further includes a camera and a controller. The camera is located at the bottom of the top plate, between the two slides and directly above the detection platform. The controller is located on the side plate and is electrically connected to the camera.

[0015] By adopting the above technical solution, the process of inspecting whether the bolt washer is qualified can be directly observed through a camera installed on the top plate. The camera transmits the photos to the controller, which automatically analyzes whether the bolt washer is qualified. This further saves the operator from the process of visual inspection and greatly improves the accuracy and efficiency of the inspection.

[0016] Optionally, the rejection cylinder is electrically connected to the controller.

[0017] By adopting the above technical solution, the camera takes pictures of the test samples during the testing process, and the controller analyzes whether the samples are qualified. If the product is unqualified, the controller will remove it directly. This not only ensures the accuracy of the test, but also saves manpower.

[0018] Optionally, the sampling assembly includes a first cylinder, a second cylinder, and a sampling cylinder. The first cylinder is located at the end of the slide groove away from the side plate. The second cylinder is located at the pushing end of the first cylinder, and the pushing direction of the second cylinder is vertically downward. The sampling cylinder is located at the pushing end of the second cylinder. There are two sets of the first cylinder, the second cylinder, and the sampling cylinder. The pushing ends of the two sets of sampling cylinders are arranged facing each other. A sample box is provided below the end of the top plate away from the detection assembly.

[0019] By adopting the above technical solution, when testing is required, the first cylinder drives the second cylinder to move to the top of the sample box, and then the second cylinder pushes downward to extend the sampling cylinder into the sample box. After the sampling cylinder is aligned with the sample, it pushes and clamps the sample. Then the second cylinder retracts out of the sample box, and the first cylinder pushes the sample to the top of the testing platform. The second cylinder pushes it downward until it is in the appropriate position, and then the sampling cylinder retracts, placing the sample in the designated position on the testing platform for testing. The above operation greatly saves the operator's sampling time and effectively improves work efficiency.

[0020] Optionally, a finished product box is provided between the sample box and the detection component, and a defective product box is provided on the side of the detection platform away from the back plate.

[0021] By adopting the above technical solution, the setting of finished product box and defective product box is more conducive to the separate collection of finished products and defective products after the detection device has completed the detection, effectively saving the physical labor of operators.

[0022] Optionally, the top end of the sampling cylinder is provided with a flexible material.

[0023] By adopting the above technical solution, after the top end of the sampling cylinder is equipped with a flexible material, the rigid contact between the sampling cylinder and the bolt pad can be effectively avoided during the sampling process, which greatly reduces the probability of sample damage.

[0024] Optionally, on the testing platform, a blocking block is provided on the side of the strip-shaped protrusion near the back plate.

[0025] By adopting the above technical solution, after the bolt washer sample is placed on the testing table, the drive motor drives the limiting plate to rotate. Since the blocking block behind the strip-shaped protrusion blocks the bolt washer sample, if the length of the bolt washer is greater than the specified length, the limiting plate cannot rotate to the vertical direction. At this time, the next step of testing can be stopped, and the unqualified products can be directly rejected, which effectively improves the testing efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The bolt washer is tested by setting up a testing component. First, the operator inverts the bolt washer on the testing table and places the arc groove of the bolt washer on the strip protrusion. If the arc groove and the two strip protrusions can fit seamlessly, it proves that the arc and length are compliant. If they cannot fit seamlessly, it proves that the product is unqualified.

[0028] Once the curvature and length are within specifications, the drive motor will rotate the limit plate along the edge of the testing platform. When the limit plate rotates to a position above the testing platform and perpendicular to it, one end of the bolt washer should be in close contact with the limit plate. The operator will then observe the positional relationship between the bolt washer and the strip-shaped protrusion. If the end of the bolt washer away from the limit plate is aligned with the edge of the strip-shaped protrusion, the width of the bolt washer is within specifications. If it is not aligned, it is a defective product.

[0029] Once the radius, length, and width meet the requirements, the operator observes the circular limit line and scale line vertically downwards through the mounting hole of the bolt washer. If the bolt washer significantly obstructs the circular limit line, it indicates that the mounting hole is incorrectly positioned. If it does not significantly obstruct the circular limit line, it is necessary to observe whether the scales on the two mutually perpendicular scale lines are the same. If the scales are the same and match the specified hole diameter, it proves that the bolt washer is a qualified product. The entire process does not require the operator to use any measuring instruments; all measurements can be performed through visual observation, greatly improving the efficiency of bolt washer inspection.

[0030] 2. By setting up a sampling component to retrieve samples from the sample box, when testing is required, the first cylinder drives the second cylinder to move to the top of the sample box, and then the second cylinder pushes downward to extend the sampling cylinder into the sample box. After the sampling cylinder is aligned with the sample, it pushes and clamps the sample, and then the second cylinder retracts out of the sample box. Then, the first cylinder pushes the sample to the top of the testing platform, and the second cylinder pushes it downward until it is in the appropriate position. After that, the sampling cylinder retracts and the sample is placed in the designated position on the testing platform for testing. The above operation greatly saves the operator's sampling time and effectively improves work efficiency.

[0031] 3. By setting up a camera, controller, and rejection cylinder and electrically connecting them, further testing of samples becomes more convenient and faster, avoiding errors caused by human observation. This results in higher accuracy in screening qualified products and saves labor costs. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] This application discloses a novel bolt washer detection device.

[0038] Reference Figure 1 , Figure 2 and Figure 3A novel bolt washer detection device includes a frame 1, a sampling component 2, and a detection component 3. The frame 1 includes a top plate 11, a back plate 12, and a side plate 13. The bottom of the top plate 11 has two symmetrical sliding grooves 111. The sampling component 2 is installed on the sliding grooves 111. The detection component 3 is located below the frame 1. The back plate 12 is welded to one side of the top plate 11 along the length of the sliding grooves 111. The side plate 13 is welded to one side of the top plate 11 along the direction perpendicular to the length of the sliding grooves 111.

[0039] The detection component 3 includes a detection platform 31, an arc detection element 32, an aperture detection element 33, a drive motor 35, and a limiting plate 34. The arc detection element 32 includes two strip-shaped protrusions 321, which are symmetrically welded to the detection platform 31. The aperture detection element 33 includes two circular limiting lines 331, which are symmetrically drawn on the detection platform 31 and located between the two strip-shaped protrusions 321. Two sets of diameter scale lines 332 are vertically drawn inside the circular limiting lines 331. Position plate 34 is hinged to the side of the test table 31 away from the back plate 12. Drive motor 35 is fixedly installed on the test table 31 by bolts, and the drive end of drive motor 35 is welded to one end of limit plate 34. On the test table 31, a blocking block 39 is welded on the side of strip protrusion 321 near the back plate 12. The length of strip protrusion 321 is the same as the specified width of bolt pad. The distance between the two strip protrusions 321 near the outer edge of the test table 31 is the same as the length of bolt pad.

[0040] Reference Figure 2 and Figure 3 The detection assembly 3 also includes a rejection component 36, a camera 37, and a controller 38. The rejection component 36 is a rejection cylinder 361, which is welded to the back plate 12 and is used to reject the detected defective products. The camera 37 is bolted to the bottom of the top plate 11, located between the two slides 111 and directly above the detection table 31. The controller 38 is bolted to the side plate 13 and is electrically connected to the camera 37 and the rejection cylinder 361.

[0041] Reference Figure 1 and Figure 2 The sampling assembly 2 includes a first cylinder 21, a second cylinder 22, and a sampling cylinder 23. The first cylinder 21 is welded to the end of the slide groove 111 away from the side plate 13. The second cylinder 22 is welded to the pushing end of the first cylinder 21, and the pushing direction of the second cylinder 22 is vertically downward. The sampling cylinder 23 is welded to the pushing end of the second cylinder 22. There are two sets of the first cylinder 21, the second cylinder 22, and the sampling cylinder 23. The pushing ends of the two sets of sampling cylinders 23 are arranged facing each other. A flexible material 231 is attached to the pushing end of the sampling cylinder 23. In this embodiment, the flexible material 231 is disclosed as a rubber pad. A sample box 4 is installed below the end of the top plate 11 away from the detection assembly 3.

[0042] Reference Figure 1 A finished product box 5 is installed between the sample box 4 and the testing platform 31, and a defective product box 6 is installed on the side of the testing platform 31 away from the back plate 12.

[0043] The implementation principle of a novel bolt washer detection device according to an embodiment of this application is as follows: When it is necessary to detect the bolt washer, the first cylinder 21 is first pushed above the sample box 4. At this time, the second cylinder 22 is pushed downward, and the sampling cylinder 23 is inserted into the sample box 4. Then, the sampling cylinder 23 is pushed towards the middle to clamp the bolt washer neatly stacked in the sample box 4. The rubber pad at the pushing end of the sampling cylinder 23 can effectively protect the bolt washer and increase the friction on the bolt washer. At this time, the second cylinder 22 is retracted, so that the sampling cylinder 23 clamps the bolt washer sample and leaves the sample box 4. Then, the first cylinder 21 sends the bolt washer sample to the detection platform 31. After the second cylinder 22 is controlled to descend to the corresponding position, the sampling cylinder 23 retracts and places the bolt washer in the corresponding position on the detection platform 31.

[0044] After the bolt washer sample is placed, the observation begins to check whether the arc groove of the bolt washer and the corresponding strip protrusion 321 can fit seamlessly. If they cannot fit, the sample is pushed forward by the rejection cylinder 361 and placed into the defective product box 6. If they fit seamlessly, it proves that the arc and length of the bolt washer sample meet the requirements.

[0045] Once the curvature and length of the bolt washer meet the requirements, the drive motor 35 is rotated, causing the limiting plate 34 to rotate upwards, so that the limiting plate 34 is tightly fitted with one end of the strip-shaped protrusion 321. If the end of the bolt washer near the limiting plate 34 is tightly fitted with the limiting plate 34, and the end of the bolt washer away from the limiting plate 34 is tightly fitted with the blocking block 39, then the width of this bolt washer sample meets the requirements. If the limiting plate 34 cannot rotate to the position where it is tightly fitted with the end of the strip-shaped protrusion 321 during the rotation process, then this bolt washer sample is a defective product. Alternatively, if the limiting plate 34 rotates to the position where it is tightly fitted with the end of the strip-shaped protrusion 321, but the end of the bolt washer sample near the blocking block 39 is not tightly fitted with the blocking block 39, then this bolt washer sample is a defective product.

[0046] Once the length, width, and curvature of the bolt washer sample are all within acceptable limits, camera 37 begins taking photos from directly above. The photos are transmitted to controller 38 for analysis. If the circular limit line 331 and diameter scale line 332 are clearly visible through the mounting holes of the bolt washer, and the graduations on the diameter scale line 332 are equal, then the bolt washer sample is a finished product. At this point, the first cylinder 21 drives the second cylinder 22 to move to the finished product position. The sampling cylinder 23 clamps the finished product, and then the first cylinder 21 controls its movement above the finished product box 5, where it is placed. If a defective product is detected at any step during the process, the rejection cylinder 361 pushes the defective product into the defective product box 6.

[0047] 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.
