Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy processing equipment, and more specifically, to an auxiliary device for a bench vise used for processing flat performance samples of aluminum alloy. Background Technology

[0002] In the tensile testing process for aluminum alloy materials, plates, profiles, and tubes with a thickness of less than 8 mm need to be processed into flat specimens. To improve processing efficiency, the industry commonly stacks specimens with the same gauge length for batch processing. The individual thickness of these flat specimens is usually between 1-5 mm. During processing, multiple specimens need to be stacked along the thickness direction, and the width direction is uniformly processed using a planer to ensure that the width of all specimens meets the standard requirements.

[0003] In this process, due to the narrow width of the tensile test specimens and the deep jaws of commonly used large bench vises, shims are needed under the specimens to elevate them to a suitable processing height. Simultaneously, the screw structure within the bench vise jaws results in insufficient surface flatness, making smooth and flat shims a crucial element for ensuring the consistency of simultaneous processing of multiple specimens. Currently, the industry commonly uses multiple shims of different widths to assemble a composite to accommodate specimens with varying layer thicknesses. However, this method has significant limitations: firstly, it is difficult to precisely match the layer thicknesses of all specimens when assembling shims, easily leading to unstable clamping or specimen suspension; secondly, when existing shims cannot meet the requirements, auxiliary specimens with the same dimensions as the original specimens must be temporarily fabricated. By adjusting the total thickness of the original and auxiliary specimens to match the width of the shims, this not only increases material and labor costs but also prolongs the processing cycle, severely restricting testing efficiency. Furthermore, the process of repeatedly assembling shims and fabricating auxiliary specimens may introduce additional clamping errors, affecting the processing accuracy of the specimens and the reliability of the test results.

[0004] Therefore, there is an urgent need to develop a bench vise auxiliary device suitable for processing flat aluminum alloy performance samples, in order to solve problems such as poor compatibility of pads, cumbersome auxiliary sample preparation, low clamping efficiency and insufficient accuracy, and to achieve efficient and accurate batch processing of samples. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for a bench vise used in processing flat performance specimens of aluminum alloys. It can solve the problems of poor compatibility of the pads used in traditional bench vises for processing flat performance specimens of aluminum alloys, the need to make additional auxiliary specimens, low clamping efficiency and insufficient accuracy, and the interference of the jaws on the milling cutter processing of specimens close to the jaws. It avoids unstable clamping due to unsuitable pad size, eliminates the auxiliary specimen making process to reduce costs, simplifies the clamping steps to improve efficiency, reduces clamping errors and ensures processing accuracy and testing reliability.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This application provides an auxiliary device for a bench vise used for processing flat performance samples of aluminum alloy, which includes a clamping assembly and a pad; the clamping assembly includes two clamping blocks and a pad arranged symmetrically, the pad is disposed on the lower surface of the clamping block, and an elastic element is disposed inside the pad; the two pads are respectively sleeved on both ends of the pad, and the elastic element abuts against the pad; wherein, the two clamping blocks and the pad form a clamping area.

[0008] Furthermore, in this invention, the length of the clamping block is greater than the length of the pad, and the protruding part of the clamping block covers the upper surface of the pad.

[0009] Furthermore, in this utility model, the aforementioned pad has a cuboid structure and matches the specifications of the pad sleeve, and the pad is made of a rigid material.

[0010] Furthermore, in this invention, the aforementioned pad has a hollow structure. The hollow structure reduces the weight of the pad, facilitating handling and the repositioning of the elastic element.

[0011] Furthermore, in this invention, the two clamping blocks have chamfered upper edges at their ends near the clamping area. The chamfer facilitates the operation of the milling machine cutter, ensuring that the edge samples in the laminated sample can also be milled.

[0012] Furthermore, in this utility model, the aforementioned elastic element is a spring or a sheet spring.

[0013] Compared with the prior art, the present invention has at least the following advantages or beneficial effects:

[0014] This invention achieves automatic adjustment of the pad width according to the thickness of the stacked sample through the cooperation of the clamping component and the pad block. The built-in elastic element can quickly reset after the clamp is released to ensure clamping consistency. Moreover, the pad block is a single smooth and flat whole, avoiding the traditional pad block splicing and auxiliary sample preparation. It not only eliminates clamping errors, improves the sample processing accuracy and testing reliability, but also simplifies the operation process and significantly improves the testing efficiency and quality of aluminum alloy flat samples.

[0021] Example 1

[0022] This embodiment provides an auxiliary device for a bench vise used in processing flat performance samples of aluminum alloys, such as... Figure 1 As shown, it includes a clamping assembly and a pad 4; the clamping assembly includes two symmetrically arranged clamping blocks 1 and a pad 2, the pad 2 is disposed on the lower surface of the clamping block 1, and an elastic element 3 is disposed inside the pad 2. The bottom and sides of the pad 2 are made of thick steel plate; the two pads 2 are respectively fitted onto the two ends of the pad 4, the elastic element 3 abuts against the pad 4, the pad 4 is embedded in the two pads 2, and the two ends abut against the elastic element 3 inside the pad 2, ensuring that the pad 4 is inside the pad 2 when the elastic element 3 is in a relaxed state; wherein, the two clamping blocks 1 and the pad 4 form a clamping area 5.

[0023] In this embodiment, the length of clamping block 1 is greater than the length of pad 2, and the protruding part of clamping block 1 covers the upper surface of pad 4. The length of clamping block 1 can be adjusted according to the sample to be clamped to facilitate clamping (shorten the clamping stroke).

[0024] Preferably, the pad 4 has a cuboid structure and matches the specifications of the pad sleeve 2. The pad 4 is made of a rigid material and is used to support the sample, keeping the sample on the same smooth and flat surface. Furthermore, the pad 4 has a hollow structure. The hollow structure reduces the weight of the pad 4, facilitating handling and the repositioning of the elastic element 3.

[0025] In the above embodiment, the two clamping blocks 1 have chamfered upper edges near the clamping area 5. The chamfering facilitates the operation of the milling cutter and ensures that the edge samples in the laminated sample can also be milled.

[0026] In addition, the elastic element 3 can be a spring or a spring sheet. The spring or spring sheet is used to maintain the position of the pad 4.

[0027] In use, place this embodiment in a bench vise, neatly arrange the stacked samples on the pad 4, and then clamp both sides of this embodiment with the bench vise. When clamping, the jaws push the pad 2 tightly, compressing its internal elastic element 3, so that the two clamping blocks 1 are close to the sample and clamped. During the process, pay attention to individual samples protruding, which may cause the stacked samples to fall apart. If there are any protrusions, tap them downwards appropriately. After clamping the sample, use a planer for milling. Because the upper edge of the clamping block 1 used for clamping in this embodiment is chamfered (45° angle) inward, the milling cutter can mill the sample at the edge of the stacked sample very well. After milling, release the jaws, flip the stacked sample, and repeat the milling. After milling both sides of the stacked sample, release the jaws, remove the sample, and the elastic element 3 pushes the pad 4 back to its original position, which is convenient for the next sample loading.

[0028] It should be noted that the thickness of a single sample to be processed is typically between 1-5 mm, and the width is 25 mm. After milling, the width is 20 mm. The thickness of a stacked sample is typically 150 mm. After the stacked sample is placed on the pad 4, its height is equal to the width of a single sample, which is 25 mm. After milling, the height is 20 mm. This embodiment is fabricated according to the sample specifications.

[0029] In summary, the embodiments of this utility model provide an auxiliary device for a bench vise used for processing flat performance samples of aluminum alloys, which has at least the following advantages or beneficial effects:

[0030] This invention, through the cooperation of the clamping component and the pad 4, enables the width of the pad 4 to be automatically adjusted according to the thickness of the stacked sample. The built-in elastic element 3 can quickly reset after the clamp is released to ensure clamping consistency. Moreover, the pad 4 is a single smooth and flat whole, avoiding the need for splicing of the traditional pad 4 and auxiliary sample preparation. This not only eliminates clamping errors and improves the sample processing accuracy and testing reliability, but also simplifies the operation process and significantly improves the testing efficiency and quality of aluminum alloy flat samples.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
