Description

Technical Field

[0001] This utility model relates to the field of hardness testing technology for automotive alloy parts, and more specifically, to a device for testing the hardness of alloy automotive parts. Background Technology

[0002] Automotive parts are the various units that constitute the overall automotive parts processing and the products that serve automotive parts processing. Hardness testing is one of the important indicators for testing material properties, and it is also one of the fastest and most economical testing methods. Hardness refers to a material's ability to resist indentation by a harder object. Depending on the testing method and applicable range, hardness units can be divided into many types, such as Brinell hardness, Vickers hardness, Rockwell hardness, and micro-Vickers hardness. Currently, hardness testing of automotive parts is conducted using a hardness tester. Before hardness testing, the upper and lower surfaces of the automotive parts need to be polished to ensure that they fit snugly against the testing platform and the testing head of the hardness tester after placement, thus making the hardness test results more accurate.

[0003] Announcement No. CN222049883U proposes a testing device for detecting the hardness of automotive parts. This device enables quick and easy positioning of automotive parts during use, improving testing efficiency. However, after fixing, the device cannot perform hardness testing on different areas of the automotive parts, thus the accuracy of the hardness test results needs to be improved.

[0004] The announcement number CN217688385U proposes a hardness tester for automotive parts production. This device is beneficial for the rapid clamping and positioning of automotive parts, thereby improving the convenience of operation. However, the device requires manual fixation and repositioning of automotive parts to complete multi-point hardness testing, which makes the operation inconvenient. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figure 1 and Figure 2 As shown, a hardness testing device for alloy automotive parts includes a hardness testing device 1 and a base 2. A testing platform 3 and a mounting frame 4 are fixed on the base 2. An automatic limit component and a thickness detection component 5 are provided on the testing platform 3. A cross slide 6 (specifically, the cross slide 6 adopts a screw structure transmission) is provided on the mounting frame 4. A lifting component is fixed on the cross slide 6. The hardness testing device 1 and a visual inspection component 7 (which is distributed in front of and behind the hardness testing device 1 and is higher than the hardness testing device 1) are fixed on the lifting component. The visual inspection component 7 can be either a visual camera or a visual sensor. The height of the visual inspection component 7 is preset and tested so that the alloy automotive parts can be completely photographed.

[0018] Specific implementation of the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the automatic limit assembly includes a fixed plate 8, a telescopic cylinder 9, and a clamping plate 10. The fixed plate 8 is symmetrically fixed on the detection table 3, and the telescopic cylinder 9 is fixed on the fixed plate 8. The telescopic cylinder 9 is connected to the clamping plates 10 that are spaced apart from the detection table 3.

[0019] Specific implementation of the embodiments of this utility model, such as Figure 1 As shown, the lifting assembly includes an electric cylinder 11 and a mounting block 12. The electric cylinder 11 is fixed on the cross slide 6, and the electric cylinder 11 is connected to the mounting block 12. The mounting block 12 is fixed with a hardness testing device 1 and a visual inspection component 7.

[0020] To further improve the accuracy of thickness detection for alloy automotive parts, the above-described embodiments are further optimized, such as... Figure 1 As shown, the thickness measuring component 5 uses a laser thickness sensor. A fixed frame 13 is fixed on the measuring table 3. Multiple laser thickness sensors are installed on the fixed frame 13. The average value of the thickness measured at multiple different locations is the thickness value of the alloy automotive part (which is also the height difference between the upper surface of the alloy automotive part and the measuring table 3).

[0021] To extend the service life of the automatic limit assembly and prevent surface wear of alloy automotive parts caused by clamping, further optimizations to the above embodiments are possible, such as... Figure 2As shown, a floating joint 14 is provided between the telescopic cylinder 9 and the clamping plate 10, and several rubber protrusions 15 are provided on the clamping plate 10. The floating joint 14 can ensure the clamping force while also allowing for fine adjustment of the clamping force angle, preventing the telescopic rod of the telescopic cylinder 9 from breaking during the clamping process. The rubber protrusions 15 contact the alloy automotive parts to avoid wear.

[0022] To better define the placement area of ​​alloy automotive parts and facilitate subsequent clamping and positioning, further optimizations to the above-described embodiments are possible, such as... Figure 2 As shown, the testing station 3 is marked with a circular placement area line 16.

[0023] In a further refinement of the embodiment of this utility model, the initial distance between the testing head of the hardness testing device 1 and the testing platform 3 is a fixed value.

[0024] It should be noted that the hardness testing device 1, thickness testing component 5, lead screw structure, visual inspection component 7, telescopic cylinder 9, and electric cylinder 11 are all electrically connected to the controller, which is shown in the figure without a number.

[0025] The working process of this utility model is as follows: First, the alloy automotive parts with the upper and lower surfaces polished are placed on the inspection table 3 and below the laser thickness sensor. Then, the thickness of the workpiece at multiple points can be detected and the average value can be taken. Then, the distance L1 between the workpiece and the inspection table 3 can be obtained. The initial distance L2 between the detection head of the hardness testing device 1 and the inspection table 3 is a fixed value. The controller can then calculate the distance L3 between the detection head of the hardness testing device 1 and the upper surface of the workpiece, L3 = L2 - L1. The alloy automotive parts are then placed within the placement area line 16 on the testing table 3. The controller then controls the automatic limit component to stably clamp the alloy automotive parts. The workpiece is then scanned by the vision inspection component, and the contour image is transmitted to the controller. The controller then controls the electric cylinder 11 to move a distance L3 so that it makes contact with the workpiece. Hardness testing is then performed on one area of ​​the alloy automotive parts. After the local hardness test is completed, the controller automatically controls the lead screw structure to operate according to the contour image and changes the testing area in conjunction with the cross slide 6. Hardness testing is then automatically performed on other areas of the workpiece (this is to perform hardness testing at different locations and take the average value to improve the accuracy of the hardness test value of the alloy automotive parts). After the hardness test is completed, the clamping is automatically released first, and then the hardness testing device 1 moves back to the initial height to unload the alloy automotive parts sample.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
