Description

Technical Field

[0001] This utility model belongs to the field of precision machining and testing technology of metal forging machinery, specifically relating to a multi-functional inspection tool for testing the femoral stem of forgings. It is an inspection fixture that integrates the straightness, length, thickness, and thickness profile dimension testing of precision forging products. Background Technology

[0002] After the titanium alloy femoral stem is forged, each product needs to be inspected for straightness, length, thickness, and thickness profile dimensions according to process requirements. Because the measurement areas are curved and irregularly shaped, the inspection is quite challenging. Traditional inspection tools require numerous fixtures; for example, thickness, thickness profile, and straightness require projectors, and length requires calipers. Traditional fixtures are also limited in function, unstable during measurement, and cumbersome and inefficient. Therefore, there is an urgent need to design a new type of fixture to solve these problems. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a multifunctional inspection tool for testing the femoral stem of forged parts. The purpose of this utility model is to design a special inspection tool that integrates multiple testing functions for measuring the straightness, length, thickness, and thickness contour of the femoral stem of a specific product. It ensures that the measurement results are stably output during the testing of each product. The structure is simple and it is convenient and quick to use.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A multifunctional inspection tool for testing the femoral stem of forged parts includes a clamping plate body. The clamping plate body has a main cavity, the shape of which is made according to the shape and size of the femoral stem. Both ends of the main cavity are provided with end caliper placement slots, and both sides of the main cavity are provided with side caliper placement slots.

[0006] Further defining the above scheme, the main cavity, the end caliper placement groove, and the side caliper placement groove are all through grooves that extend through both the top and bottom surfaces.

[0007] Further defining the above scheme, the left end of the main cavity is an arc surface made according to the corresponding position of the femoral stem, and the arc surface serves as the reference surface of the femoral stem.

[0008] To further define the above scheme, multiple side caliper placement slots are provided on both sides of the main cavity according to the requirements of the detection position.

[0009] Further specifying the above scheme, the main body of the card plate is made of a plate with a thickness of 4-5mm.

[0010] As a further limitation of the above scheme, the main body of the card plate is made of aluminum or stainless steel.

[0011] Further limitations of the above solution include a card plate support body, which includes a support base plate, with support vertical plates at the upper parts of both ends of the support base plate, and support slots at the upper parts of the two support vertical plates. The support slots are used to fit and engage with the edge of the card plate body to provide support.

[0012] As a further limitation of the above scheme, the card plate support is made of foam material.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model.

[0027] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] Please see Figure 1-4 The embodiments of this utility model are described in detail below.

[0029] Example 1: Multifunctional inspection tool for testing forged femoral stems, see reference. Figure 1-2 As shown, the device includes a clamping plate body 1, on which a main cavity 2 is provided. The shape of the main cavity 2 is made according to the shape and size requirements of the femoral stem 10, mainly for the required size of the part on the femoral stem to be tested. Both ends of the main cavity 2 are provided with end caliper placement slots 3, and both sides of the main cavity 2 are provided with side caliper placement slots 4.

[0030] In one specific embodiment, the main cavity 2, the end caliper placement groove 3, and the side caliper placement groove 4 are all through grooves that extend from top to bottom, which facilitates cooperation with the workpiece and allows the upper and lower surfaces of the femoral stem to be inspected to be exposed from the upper and lower surfaces of the gauge, making inspection easier.

[0031] The left end of the main cavity 2 is an arc surface made according to the corresponding position of the femoral stem 10. The arc surface serves as the reference surface 5 of the femoral stem 10. During testing, the corresponding end of the femoral stem 10 is close to the reference surface 5.

[0032] In this embodiment, three sets of side caliper placement slots 4 are provided on both sides of the main cavity 2 according to the requirements of the detection position.

[0033] This inspection tool consists of four parts:

[0034] (1) Place the femoral stem 10 of the product into the main cavity 2 in the main body 1 of the card plate, bend and fit it, and use a plug gauge to check its overall fit, including planar fit, straightness and thickness profile.

[0035] (2) Use the side caliper placement slots 4 distributed on the main body 1 of the caliper plate to re-inspect the thickness of the product.

[0036] (3) The maximum straightness of the gauge can be used to check whether the straightness of the product itself is qualified.

[0037] (4) Use the end caliper placement slots 3 distributed on the main body 1 of the caliper plate to detect the length of the product. Since the product reference is a curved surface, the length measurement is difficult. It can directly control its reference height to avoid large measurement errors.

[0038] This embodiment is a multi-functional special inspection tool that integrates multiple testing methods, ensuring that the measurement results of each product can be stably output during testing. Using this inspection tool makes testing more convenient and faster.

[0039] Meanwhile, the multifunctional inspection tool in this embodiment uses a pin-type plug gauge to measure the gap value between the product and the inspection tool, which can quickly obtain its straightness, thickness, and thickness profile conformity. It integrates the required inspection process, greatly facilitating personnel operation and improving inspection efficiency.

[0040] Preferably, the main body 1 of the card plate is made of a plate with a thickness of 4 to 5 mm.

[0041] Preferably, the main body 1 of the card plate is made of aluminum or stainless steel.

[0042] In this embodiment, by ensuring the dimensional accuracy of the gauge and using appropriate materials for manufacturing and processing, the gauge can be guaranteed to be durable for a long time.

[0043] Example 2: See Figure 3-4 As shown, it also includes a card plate support body 6, which includes a support base plate 7. Supporting vertical plates 8 are provided at both ends of the support base plate 7. Supporting slots 9 are provided on the upper parts of the two supporting vertical plates 8. The supporting slots 9 are used to fit and engage with the edge of the card plate body 1 for support. Preferably, the card plate support body 6 is made of foam material.

[0044] In this embodiment, by setting a card support body to support the card body, the card detection can be effectively assisted, and when the product falls, it lands on the foam base plate to avoid damage, thus protecting the product more effectively.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
