Description

Technical Field

[0001] This utility model relates to the field of workshop tool technology, and in particular to a pad for machining tensile specimens on a vertical milling machine. Background Technology

[0002] The milling cutters used in the stainless steel testing laboratory for milling stainless steel tensile specimens are non-standard custom-made KJR20PC9530 milling cutters from Croy Company. These cutters are expensive, consumed in large quantities, and can only process P17 specimens from GB / T228.1 "Metallic materials, tensile testing—Part 1: Tests at room temperature," not P5 specimens.

[0003] Currently, in the milling of tensile specimens, each specimen needs to be processed individually. It is not possible to stack multiple thin plate tensile specimens together and mill them simultaneously. Specimens need to be clamped repeatedly, resulting in low processing efficiency. Simultaneous milling of multiple tensile specimens cannot maintain their flatness, leading to inaccurate processing accuracy and high processing costs. Utility Model Content

[0004] This invention provides a pad for machining tensile specimens on a vertical milling machine, which solves the problem that existing milling machines cannot simultaneously fix multiple thin plate tensile specimens, resulting in low machining efficiency and high machining costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pad for machining tensile specimens on a vertical milling machine includes: a pad, a fixing hole, a pad base, a fixing frame, and threaded holes; the pad base is provided at the lower part of the pad; the pad base has multiple threaded holes inside; the fixing frame is provided at the upper part of the pad; multiple tensile specimens are placed in the fixing frame; and the tensile specimen fixing hole is provided in the middle of the pad.

[0007] The pad base is fixed to the milling machine worktable by bolts; multiple tensile specimens in the fixing frame are clamped and fixed by milling machine fixtures located on both sides of the pad.

[0008] Furthermore, the top of the pad base is designed to be convex in the middle and concave at both ends.

[0009] Furthermore, the multiple tensile specimens are clamped and fixed by inserting clamping blocks on the side plate of the milling machine fixture into the tensile specimen fixing holes.

[0010] Furthermore, the threaded holes inside the pad base are matched and fixedly connected with bolts.

[0011] Furthermore, the pad is made of hard alloy square steel.

[0012] Furthermore, the fixed insertion hole matches the clamping block on the milling machine fixture.

[0013] The beneficial effects of this utility model are as follows:

[0014] The pad design of this utility model provides support and fixation for tensile specimens, preventing them from moving during processing. It can fix multiple tensile specimens simultaneously, ensuring that they do not shift during processing and that the shape and dimensional tolerances of the specimens meet the standard requirements. The pad design greatly reduces vibration and noise when the vertical milling machine is processing tensile specimens, improving the surface finish of the specimens. Attached Figure Description

[0022] 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, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this utility model or its application or use. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0025] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0026] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
