Description

Technical Field

[0001] This utility model relates to the field of product quality testing technology, specifically to a product quality testing tool that facilitates comparison. Background Technology

[0002] In today's industrial production and manufacturing, product quality inspection is a crucial step in ensuring that products meet standards and customer needs. Traditional quality inspection methods have several problems and shortcomings:

[0003] Traditional inspection tools are mostly designed for individual products. For example, when inspecting the dimensions and surface quality of mechanical parts, inspectors typically fix only one part at a time and use instruments such as calipers, micrometers, and surface roughness testers to measure each parameter of that single part one by one. This method is inefficient when comparing the quality differences of multiple products from the same batch. For instance, when inspecting the thread precision of a batch of bolts, after inspecting one bolt, the fixture needs to be readjusted and the inspection instrument repositioned before the next bolt can be inspected, making it difficult to quickly and intuitively compare the differences in thread precision between different bolts.

[0004] For products with complex shapes, inspection from multiple angles is necessary. Traditional methods often require manual readjustment of the product's placement or the testing equipment's orientation when changing the inspection angle. For example, when inspecting the appearance quality of electronic product casings, such as for scratches or deformation, the irregular shape of the casing necessitates multiple rotations of the product or movement of the testing equipment to conduct a comprehensive inspection from different sides, tops, and bottoms. This not only increases inspection time but also increases the risk of human error during frequent adjustments, affecting the accuracy of the results.

[0005] When comparing the quality of two identical products, traditional testing tools cannot simultaneously fixate and test both products. For example, when testing the soldering quality of two circuit boards of the same model, to compare whether the solder joints at the same location on both circuit boards meet quality standards, the traditional method can only test one board first, record the data, then test the other board, and then perform comparative analysis. This process is prone to data confusion and inaccurate comparisons. Moreover, for situations where it is necessary to quickly screen out products with significant quality differences, this testing method is clearly unsuitable.

[0006] Based on this, this solution proposes a product quality testing tool that facilitates comparison. Utility Model Content

[0007] The purpose of this invention is to provide a product quality testing tool that facilitates comparison, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a product quality testing tool for easy comparison, comprising a base, universal wheels rotatably mounted at the four corners of the base, and a fixed frame and a fixed rod fixedly mounted on the top of the base. Two first adjusting screws are rotatably mounted on the fixed frame, and a first adjusting motor is fixedly mounted on the fixed frame. The two first adjusting screws are fixedly connected, and each of the two first adjusting screws is threaded with a movable block. A testing instrument is fixedly mounted at the bottom of each of the two movable blocks. The output shaft of the first adjusting motor is fixedly connected to the corresponding first adjusting screw. A second adjusting motor is fixedly mounted on the fixed rod, and a second adjusting screw is fixedly sleeved on the output shaft of the second adjusting motor. A mounting block is threadedly sleeved on the second adjusting screw. Two rotating shafts are rotatably mounted inside the mounting block, and a third adjusting motor is fixedly mounted on the mounting block. A worm gear is fixedly sleeved on the output shaft of the third adjusting motor. Worm wheels that mesh with the worm gear are fixedly sleeved on each of the two rotating shafts, and a mounting plate is fixedly sleeved at one end of each of the two rotating shafts. A clamping structure is provided on each of the two mounting plates.

[0009] Preferably, the clamping structure includes two auxiliary gears rotatably mounted on the mounting plate and a positioning motor fixed to the bottom of the mounting plate. Each of the two auxiliary gears is fixedly mounted with a linkage rod, and each of the two linkage rods is rotatably mounted with a clamping plate. A main gear that meshes with the corresponding auxiliary gear is fixedly sleeved on the output shaft of the positioning motor, and a support linkage rod is rotatably mounted between each clamping plate and the mounting plate.

[0010] By adopting the above technical solution, the main gear is driven to rotate by the positioning motor. The main gear meshes with the secondary gear, which drives the linkage and clamping plate to perform clamping action. This mechanical transmission method is stable and reliable, and the clamping force is uniform. At the same time, the setting of the support linkage ensures the stability of the clamping plate during the clamping process and prevents clamping instability caused by irregular product shape.

[0011] Preferably, the threads of the two first adjusting screws are arranged in opposite directions, and a first slide rail is fixedly installed on the fixed frame along the horizontal direction. Two first sliders are slidably installed on the first slide rail, and the two first sliders are respectively fixedly connected to the corresponding movable blocks.

[0012] Using the above technical solution, when the first adjusting motor drives a first adjusting screw to rotate, since the two first adjusting screws are fixedly connected and have opposite thread directions, the two moving blocks will move synchronously in opposite directions along the first slide rail. This design simplifies the adjusting mechanism, allowing the two detectors to easily adjust the spacing to meet the testing needs of products of different sizes.

[0013] Preferably, push handles are fixedly installed on both sides of the fixing frame, and brake pads are provided on any one of the casters.

[0014] By adopting the above technical solution, the push handle allows the entire testing tool to be easily moved and its position adjusted, while the brake pads ensure that the testing tool can be quickly stabilized when a fixed position is required for testing, preventing movement caused by misoperation or external interference, thus improving the safety and accuracy of testing.

[0015] Preferably, a second slide rail is fixedly installed on the fixed rod along the vertical direction, and a second slider is slidably installed on the second slide rail, with the second slider being fixedly connected to the mounting block.

[0016] By adopting the above technical solution, the second adjusting screw is driven to rotate by the second adjusting motor, which in turn drives the mounting block to move up and down along the second slide rail; this design of the second slide rail and the second slider achieves stable adjustment of the mounting block in the vertical direction.

[0017] Preferably, each clamping plate has anti-slip texture.

[0018] By adopting the above technical solution, the anti-slip texture increases the friction between the clamping plate and the product, effectively preventing the product from slipping or moving due to vibration or improper operation during the testing process, thus ensuring the smooth progress of the test and the accuracy of the results.

[0019] Preferably, a control panel is fixedly mounted on the base.

[0020] By adopting the above technical solution, the control panel integrates the control and adjustment functions of each motor, enabling operators to conveniently operate and control the entire testing tool through the control panel; this design simplifies the operation process and improves the automation and efficiency of testing.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] I. Improved testing efficiency: This utility model, by setting up two testing instruments, can simultaneously fix and test two identical products, eliminating the need to test one product at a time as in the traditional method, thus greatly saving testing time. At the same time, by using a first adjusting motor to drive a first adjusting screw, the distance between the two testing instruments can be easily adjusted to accommodate products of different sizes, improving the flexibility and efficiency of testing.

[0023] II. Multi-angle detection: This utility model, through the cooperation of the second and third adjusting motors, can adjust the position of the mounting block in the vertical direction and the rotation angle of the mounting plate in the horizontal plane respectively, thereby realizing multi-angle detection of the product. This design is particularly suitable for products with complex shapes. It can perform comprehensive detection from different sides, top and bottom angles without the need for frequent manual adjustment of the product position or the orientation of the detection instrument, thus improving the accuracy and convenience of detection.

[0024] 3. Enhanced clamping stability: The clamping structure of this utility model uses a positioning motor to drive the main gear to rotate, which in turn drives the clamping plate to clamp the product through the secondary gear and linkage rod; the anti-slip texture on the clamping plate increases the friction between the product and the clamping plate, preventing the product from slipping or moving during the inspection process; this clamping structure is not only stable and reliable, but also allows for easy control of clamping and releasing actions through the control panel, simplifying the operation process and improving work efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-4This utility model provides a technical solution: a product quality inspection tool for easy comparison, including a base 1, with universal wheels 6 rotatably mounted at the four corners of the bottom of the base 1, and a fixed frame 3 and a fixed rod 14 fixedly mounted on the top of the base 1. Two first adjusting screws 8 are rotatably mounted on the fixed frame 3, and a first adjusting motor 4 is fixedly mounted on the fixed frame 3. The two first adjusting screws 8 are fixedly connected, and each of the two first adjusting screws 8 is threaded with a movable block 10. A detector 9 is fixedly mounted at the bottom of each of the two movable blocks 10. The output shaft of the first adjusting motor 4 is fixedly connected to the corresponding first adjusting screw 8. The thread directions of the two first adjusting screws 8 are opposite. A first slide rail is fixedly mounted on the fixed frame 3 along the horizontal direction, and two first sliders are slidably mounted on the first slide rail. The first slider is fixedly connected to the corresponding movable block 10. The second adjusting motor 11 is fixedly installed on the fixed rod 14. The output shaft of the second adjusting motor 11 is fixedly sleeved with the second adjusting screw 12. The second adjusting screw 12 is threadedly sleeved with the mounting block 13. The second slide rail is fixedly installed on the fixed rod 14 along the vertical direction. The second slider is slidably installed on the second slide rail. The second slider is fixedly connected to the mounting block 13. Two rotating shafts 16 are rotatably installed inside the mounting block 13. The third adjusting motor 15 is fixedly installed on the mounting block 13. The output shaft of the third adjusting motor 15 is fixedly sleeved with the worm gear 17. The two rotating shafts 16 are both fixedly sleeved with worm wheels 18 that mesh with the worm gear 17. One end of the two rotating shafts 16 is fixedly sleeved with a mounting plate 19. The two mounting plates 19 are both provided with clamping structures.

[0032] In this embodiment, the first adjusting motor 4 is started, and its output shaft drives a first adjusting screw 8 to rotate. Since the two screws are fixedly connected and have opposite thread directions, the two movable blocks 10 will move in opposite directions at the same time, thereby realizing the adjustment of the detector in the horizontal direction. The second adjusting motor 11 is started, and its output shaft drives the second adjusting screw 12 to rotate, thereby moving the mounting block 13 in the vertical direction, thereby adjusting the distance between the detector 9 and the mounting block 13, which facilitates the adjustment of the distance between the detector 9 and the product to be tested.

[0033] Combination Figure 1-4 As shown, in this embodiment, the clamping structure includes two auxiliary gears 22 rotatably mounted on the mounting plate 19 and a positioning motor 20 fixed to the bottom of the mounting plate 19. Each of the two auxiliary gears 22 is fixedly mounted with a linkage rod 23, and each of the two linkage rods 23 is rotatably mounted with a clamping plate 24. The output shaft of the positioning motor 20 is fixedly sleeved with a main gear 21 that meshes with the corresponding auxiliary gear 22. Each of the two clamping plates 24 is rotatably mounted with a support linkage rod 2 between it and the mounting plate 19. Each clamping plate 24 is provided with anti-slip texture 25.

[0034] In this embodiment, the product to be tested is placed between two corresponding clamping plates 24. The positioning motor 20 is started, and its output shaft drives the main gear 21 to rotate. The main gear meshes with the secondary gear 22, which in turn drives the linkage 23 and the clamping plate 24 to rotate. Through the support of the support linkage 2, the clamping plate firmly clamps the product. The clamping structure can stably clamp the two products, which is convenient for subsequent comparison. By starting the third adjustment motor 15, its output shaft drives the worm gear 17 to rotate. The worm gear 17 meshes with two worm wheels 18, which in turn drives the two rotating shafts 16 and the mounting plate 19 to rotate, realizing the angle adjustment of the product on the horizontal plane, which is convenient for multi-angle product testing. Since two products can be clamped and tested at the same time, it is convenient to compare the quality differences of products in the same batch.

[0035] Combination Figure 1-4 As shown, in this embodiment, push handles 5 are fixedly installed on both sides of the fixed frame 3, and brake pads are provided on any one of the universal wheels 6.

[0036] In this embodiment, the casters 6 installed at the bottom of the base 1 facilitate the movement of the entire device, and the brake pads installed on any one of the casters 6 can ensure that the device is fixed in place when needed.

[0037] Combination Figure 1-4 As shown in this embodiment, a control panel 7 is fixedly installed on the base 1.

[0038] In this embodiment, the entire testing tool can be conveniently operated and controlled via the control panel 7. The control panel 7 may integrate control buttons or a touch screen interface for the first adjusting motor 4, the second adjusting motor 11, the third adjusting motor 15, and the positioning motor 20, allowing operators to adjust the movement state of each part according to actual needs, thereby enabling quality testing and comparison of products of different specifications, positions, and angles.

[0039] Working principle of this utility model:

[0040] By starting the first adjusting motor 4, its output shaft drives a first adjusting screw 8 to rotate. Since the two screws are fixedly connected and have opposite thread directions, the two movable blocks 10 will move in opposite directions simultaneously, thereby achieving the adjustment of the detector in the horizontal direction. By starting the second adjusting motor 11, its output shaft drives the second adjusting screw 12 to rotate, thereby moving the mounting block 13 in the vertical direction, thereby adjusting the distance between the detector 9 and the mounting block 13, which facilitates the adjustment of the distance between the detector 9 and the product to be tested.

[0041] The product to be tested is placed between the two corresponding clamping plates 24. The positioning motor 20 is started, and its output shaft drives the main gear 21 to rotate. The main gear meshes with the secondary gear 22, which in turn drives the linkage 23 and the clamping plate 24 to rotate. With the support of the support linkage 2, the clamping plate firmly clamps the product. The clamping structure can stably clamp the two products, which is convenient for subsequent comparison. By starting the third adjustment motor 15, its output shaft drives the worm gear 17 to rotate. The worm gear 17 meshes with the two worm wheels 18, which in turn drives the two rotating shafts 16 and the mounting plate 19 to rotate, realizing the angle adjustment of the product on the horizontal plane, which is convenient for multi-angle product testing. Since two products can be clamped and tested at the same time, it is convenient to compare the quality differences of products in the same batch.

[0042] The detection parameters are set through the control panel 7, and the detector 9 is started to detect the clamped product. It also facilitates the adjustment of the first adjustment motor 4, the second adjustment motor 11, and the third adjustment motor 15. After the detection is completed, the detection results can be viewed and recorded through the control panel 7 for subsequent analysis.

[0043] In summary, this patent, through its flexible adjustment mechanism and clamping structure, enables convenient, efficient, and accurate comparative testing of products, greatly improving the efficiency and accuracy of product quality testing.
