Description

Technical Field

[0001] The utility model relates to the field of processing tooling, in particular to a positioning tooling for casting test blocks. Background Art

[0002] Casting test blocks are test samples made during the casting production process. Their size, shape, and material need to meet the design requirements. As the "standard parts" of casting production, test blocks are used to evaluate whether the actual performance of castings meets the standards. By conducting experiments on test blocks, such as testing mechanical properties such as tensile, compressive, and bending, and analyzing chemical components, it can be verified whether the mechanical properties and chemical properties of castings meet the design requirements, ensuring the quality of castings. The experimental results of casting test blocks can be used to guide the adjustment and optimization of casting processes.

[0003] In the prior art, a casting test block needs to be first sawed into small test pieces and corresponding tests are carried out separately to verify its mechanical properties and chemical properties. When sawing, the casting test block is fixed on the sawing machine workbench through tooling. The tooling includes two jaws that can move relative to each other and move away from each other, and a lead screw mechanism for driving the jaws to move. The casting test block is clamped by the two jaws, and a saw blade is used for sawing. During cutting, the length direction of the saw blade is consistent with the width direction of the casting test block.

[0004] Since there is more than one casting test block to be sawed, it is necessary to ensure that each small test piece has the same width and there is no dimensional variable to ensure the accuracy of the comparative test results. Moreover, since some sawing machines do not have the function of determining the processing reference, during clamping, it is necessary to ensure that the ends of each casting test block are in the same horizontal position on the sawing machine workbench. However, with the above technical solutions, the tooling cannot position the ends of the casting test blocks. It is necessary to use measuring tools to measure the saw blade and the end face of the newly replaced casting test block, and adjust the position of the tooling multiple times to ensure that the sizes of the cut small test pieces are consistent, which greatly affects the work efficiency.

Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0028] like Figure 1 As shown, this specific embodiment provides a casting test block positioning tool, including a base 1, a positioning assembly and a push plate 3; the positioning assembly includes a limiter 9, which sends a corresponding signal when the test block is in contact; the push plate 3 is movably arranged on the base 1, and the push plate 3 is arranged opposite to the limiter 9; the clamping assembly includes two relatively arranged jaws 6, the jaws 6 are movably arranged on the base 1, and the two jaws 6 can move relative to and back to each other, and the moving direction of the jaws 6 is perpendicular to the moving direction of the push plate 3.

[0029] This specific implementation method can position the end of the casting specimen through the cooperation of the push plate 3 and the limit member 9. When a new specimen of the same size is obtained by optimizing the casting process for the same molten iron, the lateral position of the new casting specimen on the tooling can be ensured to be the same as that of the previous specimen, thereby ensuring the consistency of the sawing position of the saw blade and thus ensuring the lateral size of the sawed small specimen. When performing performance tests, the only variable is the casting process of the small specimen, and there are no dimensional variables, thereby ensuring the accuracy of the test results. There is no need to measure and adjust the tooling position, thereby improving work efficiency.

[0030] like Figure 1 As shown, the limit member 9 can adopt a block-shaped limit block, which is directly installed on the base 1 to realize hard limit. In this specific embodiment, in order to realize automatic control, the limit member 9 adopts a proximity sensor. When the casting specimen is pushed by the push plate to contact the limit member 9, the limit member 9 sends an electrical signal to the sawing machine control system, and the sawing machine control system sends the next operation instruction, which greatly improves the automation level.

[0031] like Figure 1As shown in the figure, in order to avoid the influence of the vibration of the casting specimen during sawing on the limiting member 9, in this specific embodiment, the positioning assembly further includes a support arm 10 and a driving member 8. One end of the support arm 10 is rotatably arranged on the base 1, the support arm 10 can rotate in the vertical plane, the other end of the support arm 10 is provided with a limiting member 9, the driving member 8 is arranged on the base 1 through a hinge seat, the driving member 8 includes a telescopic rod, and the end of the telescopic rod is hinged to the support arm 10; when the telescopic rod extends, the support arm 10 swings up, driving the limiting member 9 away from the specimen; in this specific embodiment, the driving member 8 adopts an electric telescopic rod 2.

[0033] As Figure 1 shown in the figure, in this specific embodiment, a slider is arranged at the lower part of the push plate 3, a chute is arranged at the corresponding position of the base 1, and the slider can move along the chute, which has a guiding effect and prevents the push plate 3 from tilting when moving. The push plate 3 is connected to the electric telescopic rod 2, and the electric telescopic rod 2 is arranged on the base 1; the push plate 3 is in an L-shaped structure, and anti-slip grooves are arranged on the contact end surface of the push plate 3 and the casting test block.

[0035] As Figure 1 shown in the figure, in this specific embodiment, the casting specimen is sawn into two small specimens. To ensure the clamping stability, two sets of clamping assemblies are provided. During sawing, the clamping assemblies are respectively located on both sides of the saw blade. An over-travel groove is arranged on the base 1 between the two sets of clamping assemblies, and the length direction of the over-travel groove is the same as the moving direction of the clamping jaw 6. By arranging the over-travel groove, the saw blade can damage the base 1.

[0036] In this specific embodiment, the electric telescopic rod 2, the driving motor 4, and the driving member 8 are all electrically connected to the sawing machine control system. The sawing machine control system stores positioning and clamping programs to achieve the positioning and clamping of the casting specimen.

[0037] The working process of this casting specimen positioning tooling is as follows:

[0038] According to the transverse dimension of the casting specimen 5, adjust the position of the limit block; place the casting specimen 5 between the jaws 6, and the control system of the sawing machine controls this tooling to perform the positioning action.
