Description

Technical Field

[0001] The present application relates to the technical field of impact testing, and in particular to an impact testing composite tool, a calibration device, and a sample device. Background Art

[0002] The anvil span of the impact testing machine directly affects the accuracy of the impact test results. The traditional method of calibrating the impact testing machine is to measure the anvil span with a vernier caliper, and then adjust its position according to the measurement results. It usually takes several adjustments to meet the span requirements; after the span is determined, the pendulum is lowered, and while ensuring that the anvil span remains unchanged, the distance from the two anvils to the pendulum is adjusted to make them consistent.

[0003] When calibrating impact testing machines in batches, the need for repeated measurements and adjustments leads to low efficiency, large errors, a significant impact from human factors, and potential safety hazards. When calibrating, operators often need to bend over and squat, which consumes a lot of physical energy and has poor working conditions, which can easily lead to occupational diseases related to lumbar disc disease.

[0004] In addition, after replacing the impact specimen, the impact specimen needs to be re-centered to avoid affecting the test results. Therefore, after replacing the impact specimen, the operation of ensuring that the impact specimen is placed in the center also takes a lot of time, and different impact specimen fixing tools need to be set up, which increases costs.

[0036] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] The embodiments of the present application provide an impact test composite tool, calibration device and specimen device to solve the problem in the related art that the impact testing machine needs to be repeatedly adjusted multiple times during calibration and when the impact specimen is replaced and re-centered, which takes a long time and leads to low efficiency.

[0038] See also Figure 5 In a first aspect, an impact test composite tool comprises:

[0039] The calibration block 1 has a specimen mounting surface on its top and a V-shaped groove 2 on its bottom; the sharp corners of the V-shaped groove 2 face the top of the calibration block 1; and the two ends of the V-shaped groove 2 in the extending direction pass through the two opposite side surfaces of the calibration block 1;

[0040] Anvil support member 3 is mounted on the side of calibration block 1 , on which side a V-shaped groove 2 is provided. There are two anvil support members 3 , which are symmetrically distributed with the center line of the V-shaped groove 2 as the axis of symmetry.

[0041] When calibrating the impact test composite tool, its posture is adjusted so that the V-shaped groove 2 is set horizontally, and then the anvil is adjusted so that the anvil and the supporting member 3 are in contact with each other to complete the calibration, and no adjustment is required after measurement; during the specimen test, the impact specimen is connected to the calibration block 1 through the specimen mounting surface, so that the V-shaped groove 2 is set vertically. Since the calibration block 1 is used to fix the impact specimen after calibration and centering, the calibration block 1 can be directly placed against the anvil again without the need for centering adjustment, thereby reducing adjustment time and allowing the calibration block 1 to be reused under different working conditions, suitable for different specimens, and improving efficiency.

[0042] The following details the steps that are performed in the example of calibrating an impact tester:

[0043] The first step, such as Figure 1 and 2 As shown, the calibration block 1 is placed on the impact testing machine and located between two anvils, with the V-shaped groove 2 in a horizontal state.

[0044] The second step is Figure 3 and 4 As shown, lower the pendulum and snap it into the V-shaped groove 2 of the calibration block 1 in a vertical state.

[0045] The third step is to adjust the position of the anvil so that it just contacts the two anvil abutting members 3, ensuring that the span of the anvil is accurate and does not require multiple in and out measurements for adjustment.

[0046] Step 4: Lock the anvil, lift the pendulum, and take out the calibration block 1.

[0047] The steps of the utility model in the impact test example are as follows:

[0048] The first step, such as Figure 5 As shown, place the calibration block 1 as Figure 3 Assembled as a tool for alignment.

[0049] The second step is Figure 6 and Figure 7 As shown, install the impact specimen on the specimen mounting surface.

[0050] The third step, such as Figure 6 and Figure 7 As shown, place the impact specimen and the centering tool in accordance with Figure 4 The calibration block 1 is placed on the anvil, that is, the calibration block 1 is turned over so that the V-shaped groove 2 is in a vertical state, the impact specimen contacts the anvil, and the anvil support member 3 supports the anvil.

[0051] The fourth step is to take out the centering tool vertically, that is, remove the impact specimen from the specimen installation surface.

[0052] Step 5: Start the impact test.

[0053] In some preferred embodiments, the following configurations are provided to achieve connection and removal of impact specimens:

[0054] The impact testing machine calibration and centering tool also includes a specimen clamping plate 4, which is removably connected to the specimen mounting surface via a connector. The specimen clamping plate 4 comprises a rectangular plate that is the same size as the specimen mounting surface and is equipped with two spaced-apart engaging bosses 400. These bosses 400 are equipped with elastic pads for supporting the specimen. These pads prevent the specimen from falling out due to an unstable engagement.

[0055] The specimen mounting surface and the rectangular plate are both provided with connecting screw holes; the connecting members include screws or bolts. This structure enables simple locking and unlocking.

[0056] The anvil support member 3 comprises a rectangular bar, the length of which is equal to the distance between the top and the bottom of the calibration block 1. This arrangement ensures that the anvil support member 3 can be in contact with the anvil in different modes of use.

[0057] Second, reference Figures 1-4 , an impact test calibration device, comprising:

[0058] a base 5 on which a pendulum assembly 6 is provided;

[0059] Two L-shaped anvils 7 are spaced apart and mounted on the base 5 through an adjustment assembly; each L-shaped anvil 7 comprises a horizontal portion and a vertical portion, the horizontal portion being located below the vertical portion; the horizontal portion and the vertical portion are marked a and b respectively.

[0060] Impact test composite tool, the two anvil abutting members 3 of the impact test composite tool respectively abut against the corresponding horizontal parts.

[0061] Thirdly, reference Figure 5-Figure 7 , an impact test specimen device, comprising:

[0062] a base 5 on which a pendulum assembly 6 is provided;

[0063] Two L-shaped anvils 7 are spaced apart and mounted on the base 5 via an adjustment assembly; each L-shaped anvil 7 includes a horizontal portion and a vertical portion, with the horizontal portion being located below the vertical portion;

[0064] Impact test composite tool, the two anvil abutment members 3 of the impact test composite tool respectively abut against the corresponding vertical parts, the calibration block 1 is connected to the sample clamping plate 4; the impact test composite tool is connected to the impact sample through the sample clamping plate 4. The impact sample is marked as c, reference Figure 5 shown.

[0065] The adjustment assembly of the impact test calibration device and the impact test specimen device includes a slide rail mounted on a base 5, on which slide two spaced brackets 8 are slidably mounted. Each bracket 8 is connected to an L-shaped anvil 7. Each bracket 8 is connected to a telescopic rod, which is arranged opposite each other and mounted on the base 5. The telescopic rod is used to drive the corresponding bracket 8 along the slide rail. The telescopic rod is a screw structure with a movable seat threaded onto the screw, which is connected to the bracket 8. Alternatively, the telescopic rod can include an electric telescopic rod and a hydraulic rod.

[0066] As described above, since the L-shaped anvil 7 includes a horizontal portion and a vertical portion, and the horizontal portion is located below the vertical portion, it can be used in conjunction with impact test composite tools in different states.

[0067] Its simple assembly can become a composite tool for placing impact specimens in the center, greatly improving the utilization rate of the tool without the need for centering. The pendulum is lowered and stuck into the V-groove 2 of the calibration block 1, and the anvil is moved to press against the outer side of the anvil support 3 of the calibration block 1, which ensures that the pendulum is located in the middle of the anvil and also ensures that the span of the anvil is accurate, completing the calibration of the anvil of the impact testing machine more quickly and accurately. When calibrating impact testing machines in batches, there is no need to repeatedly measure and adjust, avoiding the influence of human factors and the existence of safety hazards; and avoiding the problem that operators often need to bend over and squat when calibrating it, which consumes a lot of physical energy and has poor working conditions, and is prone to causing occupational diseases of lumbar intervertebral disc. The overall principle of this tool is simple, the size is small, the weight is light, it is convenient for mobile operation, has low environmental requirements, and has a wide range of applications.
