Description

Technical Field

[0001] This utility model relates to the field of automatic testing of Vickers hardness testers, and in particular to an automatic stage device for multi-station Vickers hardness testers. Background Technology

[0002] In Vickers hardness testing, the conventional method involves manual movement and single-point testing. With the development of automation technology, some large-face specimens can now be automatically tested at multiple points in different areas of the same specimen. However, for small-section specimens, especially thin-section Vickers hardness specimens that are prone to tipping, there is a lack of a method for continuous automatic testing at multiple points on different specimens. Utility Model Content

[0003] To address the aforementioned technical problems, this invention provides an automatic stage device for a multi-station Vickers hardness tester. Taking into account the characteristics of Vickers hardness testing with small end faces and thin cross-sections, this device, through targeted design, automatically and continuously tests Vickers hardness samples of different thicknesses, end face sizes, and test point requirements on the same device. The technical means employed in this invention are as follows:

[0004] An automatic stage device for a multi-station Vickers hardness tester includes a stage body. The stage body is disposed at the bottom of the Vickers hardness tester and can feed along its length. A reference block is disposed on the upper surface of the stage body along its centerline. Stops are disposed on the reference block at preset distances on both sides of the reference block. The sample to be tested can be blocked by the stops at the corresponding testing position. Each stop is provided with a fastening jaw, which is disposed on the side of the stage body near the side.

[0005] Furthermore, a movable module is provided at the bottom of the support platform body. The movable module includes an X-axis module and a Y-axis module. The X-axis module includes an X-axis motor and an X-axis slide rail. An X-axis slider capable of moving along the X-axis slide rail is provided at the bottom of the support platform body. The X-axis motor is connected to the X-axis slider. The Y-axis module includes a Y-axis motor and a Y-axis slide rail. The Y-axis slide rail is perpendicular to the X-axis slide rail. A Y-axis slider capable of moving along the Y-axis slide rail is provided at the bottom of the X-axis slide rail. The Y-axis motor is connected to the Y-axis slider.

[0006] Furthermore, the reference block has screw holes and is mounted on the support platform body by means of hexagon socket bolts.

[0007] Furthermore, the fastening claw is provided with screw holes, and is installed on the support platform body by means of hexagon socket bolts.

[0008] This invention has the following advantages: The movable module within the device enables the feeding of the support platform along its length, allowing samples to continuously enter the testing range of the Vickers hardness tester, thus achieving automatic continuous testing of multiple samples. Through the cooperation of the stop blocks and clamping jaws, it can effectively limit and block samples of different shapes and small cross-sections, especially thin-section Vickers hardness samples that are prone to tipping, thus completing the testing.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] like Figures 1-5As shown in the figure, this utility model embodiment discloses an automatic stage device for a multi-station Vickers hardness tester, including a stage body 1. The stage body 1 is disposed at the bottom of the Vickers hardness tester 8 and can complete the feeding of the stage along the length direction. A reference block 2 is disposed on the upper surface of the stage body along the center line of its length direction. Stop blocks 3 are disposed on the reference blocks at preset distances on both sides of the reference blocks. The sample to be tested can be blocked by the stop blocks at the corresponding testing position. Each stop block 3 is correspondingly provided with a fastening claw 4. The fastening claw is disposed on the side of the stage body near the side.

[0018] Specifically, the ability to feed the support platform along its length is achieved by having a moving module at the bottom of the support platform body. The moving module includes an X-axis module 6 and a Y-axis module 7. The X-axis module includes an X-axis motor and an X-axis slide rail. An X-axis slider capable of moving along the X-axis slide rail is located at the bottom of the support platform body, and the X-axis motor is connected to the X-axis slider. The Y-axis module includes a Y-axis motor and a Y-axis slide rail. The Y-axis slide rail is perpendicular to the X-axis slide rail. A Y-axis slider capable of moving along the Y-axis slide rail is located at the bottom of the X-axis slide rail, and the Y-axis motor is connected to the Y-axis slider.

[0019] The reference block has screw holes and is installed on the support platform body by means of hexagonal socket bolts.

[0020] The fastening claw has a screw hole, and it is installed on the support platform body by means of an internal hex bolt 5.

[0021] In this embodiment, there are 8 stops and 8 clamping jaws, which means that up to 8 test blocks can be tested at once. In other optional embodiments, this number can be adjusted. Even when the hardness tester is large enough, the reference block is not set alone, and array testing is performed. In this state, the number and position of the stops and clamping jaws must still be matched. In this embodiment, the test can be completed by one X-axis module, and the Y-axis module is mainly used for fine adjustment. In the above-mentioned "other optional embodiments", more attention needs to be paid to the control and allocation of the X-axis module and the Y-axis module.

[0022] In this embodiment, the clamping jaws are designed to prevent the sample from detaching from the testing station during the testing process. The term "jaws" refers to their claw-shaped design at the contact point with the sample. In other optional embodiments, other structures that can work with a stop block to prevent sample detachment can be used instead. Furthermore, in the field of Vickers hardness testing, sample structures are mostly standard or modular. For tests using different standards, as a further implementation, the clamping jaws are detachable, and their length and specifications can be adjusted for different tests. After installation, they are secured with hexagonal bolts. For thin, easily tipped samples, clamping jaws positioned next to the testing station are used for lateral fixation. Through these measures, continuous automatic testing of different samples at multiple points is achieved.

[0023] Similarly, the reference block is a detachable component, and the stop block is preferably fixedly installed on it. When different standards need to be tested, directly replacing the reference block is also a preferred method, which can complete the division of the workstation on the device plate and realize the simultaneous placement of multiple samples.

[0024] The above methods, especially the control of the X-axis module and Y-axis module, can also be achieved by manual operation by the staff. By adjusting the movement of the motor, the pre-test sample can be placed under the hardness tester.

[0025] As another preferred method, namely intelligent and automated methods, the detection of individual samples at specific points can be achieved by setting the zero-point coordinates of each station. The test points of each sample are located and detected sequentially using the zero-point coordinates of each station until all samples on the device have been tested.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
