Description

Technical Field

[0001] This utility model relates to the field of plastic packaging box production technology, specifically a fixture for quickly testing the deformation of products. Background Technology

[0002] In the production process of injection-molded square toolboxes, in order to ensure that the product meets customer requirements, it is usually necessary to control the product's deformation. This requires measuring the produced square toolboxes.

[0003] In existing technologies, deformation testing is typically performed by workers directly using calipers to measure the injection-molded square toolbox and then recording the results. This method has the following problems: during the testing process, differences in personnel can lead to deviations in the test, resulting in inaccurate test results; and the use of calipers for measurement is inefficient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a fixture for quickly testing the deformation of products. Different types of inspection fixtures are installed on a fixed base through an installation mechanism. When one of the inspection fixtures is damaged, it can be removed and replaced without replacing all of them. During testing, the staff only needs to place the product on the corresponding inspection fixture. The testing efficiency is high and the stability is good, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for rapidly testing the deformation of a product, comprising a fixed base, wherein uniformly distributed inspection fixtures are mounted on the upper surface of the fixed base, and a mounting mechanism is also included.

[0006] The installation mechanism includes positioning posts, positioning slots, clearance slots, sliding posts, ejector plates, and fixing components. The upper surface of the fixing base has placement slots that correspond one-to-one with the inspection fixtures. The upper surface of each placement slot is provided with a positioning post. The bottom wall of each inspection fixture is provided with a positioning slot. Each positioning post is inserted into the interior of an adjacent positioning slot. Each clearance slot inside the positioning post is slidably connected to a sliding post. Each sliding post has an ejector plate at its upper end. Each inspection fixture is installed inside the corresponding placement slot through the fixing components.

[0007] Furthermore, the fixing component includes magnets and latches. Magnets are provided in the mounting grooves one opened on the upper surface of the placement groove, and latches are provided in the mounting grooves two on the bottom wall of the inspection fixture. The magnets are magnetically attracted and fixed to the corresponding latches, which facilitates fixing the inspection fixture in the corresponding mounting groove.

[0008] Furthermore, the installation mechanism also includes a push plate and a limiting component. The lower end of each sliding column is provided with a push plate, and each sliding column is slidably connected to the interior of the corresponding clearance groove through the limiting component, which facilitates the sliding and limiting of the sliding column.

[0009] Furthermore, the limiting component includes a limiting ring and a spring. The outer surface of each slide column is fixedly fitted with a limiting ring, and the outer surface of each slide column is movably fitted with a spring. The springs are located between the upper surface of the adjacent limiting ring and the top wall of the clearance groove, which facilitates the reset of the slide column.

[0010] Furthermore, the limiting component also includes ribs and rib grooves. Ribs are provided on both the front and rear sides of the limiting ring, and rib grooves are provided on both the front and rear sides of the inner wall of the clearance groove. The ribs are slidably connected to the interior of the adjacent rib grooves, which facilitates the sliding limiting of the limiting ring.

[0011] Furthermore, the upper surface of the ejector plate is provided with rubber pads, and the upper surface of the rubber pads is in contact with the top wall of the adjacent positioning groove, which helps to reduce damage to the positioning groove of the inspection fixture.

[0012] Furthermore, the upper surface of the inspection fixture is provided with a model groove to facilitate the staff to read the specific model of the inspection fixture.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When the inspection fixture is damaged and needs to be replaced, push the corresponding push plate. The sliding column drives the ejector plate to move upward. The rubber pad pushes the top wall of the positioning groove. When the pushing force is sufficient to overcome the spring's rebound force and the magnetic attraction between the magnet and the latch, the damaged inspection fixture can be ejected from the placement groove. The inspection fixture is easy to disassemble and assemble. Only the damaged inspection fixture needs to be removed and replaced. It is not necessary to replace all of them.

[0015] 2. During testing, place the opening of the square toolbox to be tested on the corresponding model inspection fixture, and press the square toolbox downwards. As the toolbox is pressed down, it will deform outwards from the opening. Qualified products will complete the deformation, while unqualified products will break or fail to deform during the deformation process. This allows for quick verification of whether the product meets the requirements. The testing process is simple to operate, with high accuracy and stability. The test results will not be affected by differences in operator operation. All inspection fixtures are installed in placement slots on the fixed base via an installation mechanism, making them easy to manage and less likely to be lost. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-5 This embodiment provides a technical solution: a fixture for rapidly testing the deformation of a product, including a fixed base 1, with uniformly distributed inspection fixtures 2 mounted on the upper surface of the fixed base 1, and each inspection fixture 2 having a model groove 5 on its upper surface.

[0024] It also includes an installation mechanism 4; the installation mechanism 4 includes positioning posts 41, positioning grooves 42, clearance grooves 43, sliding posts 44, ejector plates 45 and fixing components 47. The upper surface of the fixing base 1 is provided with placement grooves 3 corresponding to the inspection fixtures 2. The upper surface of each placement groove 3 is provided with positioning posts 41. The bottom wall of each inspection fixture 2 is provided with positioning grooves 42. The positioning posts 41 are inserted into the interior of adjacent positioning grooves 42. Each clearance groove 43 inside the positioning posts 41 is slidably connected to a sliding post 44. Each upper end of the sliding post 44 is provided with an ejector plate 45. Each inspection fixture 2 is installed inside the corresponding placement groove 3 through the fixing components 47. The installation mechanism 4 also includes a push plate 46 and a limiting component 48. Each lower end of the sliding post 44 is provided with a push plate 46. Each sliding post 44 is slidably connected inside the corresponding clearance groove 43 through the limiting components 48.

[0025] The fixing component 47 includes a magnet 471 and a latch 472. The mounting groove 1 on the upper surface of the placement groove 3 is provided with a magnet 471, and the mounting groove 2 on the bottom wall of the inspection fixture 2 is provided with a latch 472. The magnet 471 is magnetically fixed to the corresponding latch 472.

[0026] The limiting component 48 includes a limiting ring 481 and a spring 482. The outer surface of the sliding column 44 is fixedly fitted with the limiting ring 481, and the outer surface of the sliding column 44 is movably fitted with the spring 482. The spring 482 is located between the upper surface of the adjacent limiting ring 481 and the top wall of the clearance groove 43. The limiting component 48 also includes ribs 483 and rib grooves 484. Ribs 483 are provided on both the front and rear sides of the limiting ring 481, and rib grooves 484 are provided on both the front and rear sides of the inner wall of the clearance groove 43. The ribs 483 are slidably connected to the interior of the adjacent rib grooves 484. The upper surface of the ejector plate 45 is provided with rubber pads 6, and the upper surface of the rubber pads 6 is in contact with the top wall of the adjacent positioning groove 42.

[0027] The working principle of this utility model is as follows:

[0028] When a deformation test is required, the staff reads the model number of the inspection fixture 2 by reading the model number engraved in the model number groove 5 on the inspection fixture 2. Then, the opening of the square toolbox to be tested is placed on the corresponding model of the inspection fixture 2, and then the square toolbox is pressed down. During the downward process, under the pressure and the action of the inspection fixture 2, the square toolbox will deform outward from the opening. Qualified products can complete the deformation, while unqualified products will break or fail to deform during the deformation process. This allows for quick inspection of whether the product meets the requirements. The testing process is simple to operate, and the accuracy and stability of the test are high. The test results will not be affected by differences in the operation of the staff. All inspection fixtures 2 are installed in the placement groove 3 on the fixed base 1 through the installation mechanism 4, which is easy to manage and not easy to lose.

[0029] When inspection fixture 2 is damaged and needs to be replaced, the operator pushes the push plate 46 below the damaged inspection fixture 2. Under the constraint of the rib groove 484 and rib 483, the push plate 45 moves upward via the sliding column 44, driving the ejector plate 45 upward. This pushes the top wall of the positioning groove 42 of the inspection fixture 2 through the rubber pad 6. When the pushing force is sufficient to overcome the rebound force of the spring 482 and the magnetic attraction between the magnet 471 and the latch 472, the magnetic attraction between the magnet 471 and the latch 472 is released, and then the ejector plate 45 can be ejected. The inspection fixture 2 is pushed out of the placement slot 3 by the rubber pad 6. (After the push plate 46 is released, the spring 482 drives the limit ring 481 to move downward along the clearance slot 43 through the rebound force, so that the sliding column 44 returns to its original position.) After removing the damaged inspection fixture 2, the positioning slot 42 of the new inspection fixture 2 is aligned with the positioning column 41. Then the inspection fixture 2 is moved downward until the magnet 471 and the latch 472 are fixed together by magnetic attraction. The inspection fixture 2 is then fixed in the corresponding placement slot 3, and the replacement of the inspection fixture is completed.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
