Description

Technical Field

[0001] This utility model relates to the field of valve cover type wax film detection tools, and in particular to a valve cover type special wax film detection tool. Background Technology

[0002] With the continuous development of my country's industry, the demand for castings is gradually increasing. The variety of casting structures is also growing. Castings are widely used in fluid valve castings, aviation, automobiles, machinery and other fields. As the application of castings becomes more widespread, the requirements for the internal quality of castings are also becoming higher and higher. During casting, due to the characteristics of the product structure, it is often impossible to measure many special dimensions of castings using only general measuring tools. For castings with special dimensional requirements, special inspection tools need to be designed to ensure that the castings meet the customer's requirements and produce qualified products.

[0003] Currently, inspecting valve cover castings is quite cumbersome, as it is inconvenient to directly measure the internal shape and whether the large plane is perpendicular to the casting, which reduces the production efficiency of casting inspection. To address this issue, we propose a special wax film inspection tool for valve covers. Utility Model Content

[0004] The purpose of this utility model is to provide a valve cover-type special wax film detection tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A valve cover type special wax film detection tool includes a base plate, on the upper surface of which are fixedly connected symmetrical fixing plates. A first bearing is fixedly embedded on the side of each of the two fixing plates that are close to each other. A rotating rod is fixedly connected to the inner ring of each of the two first bearings. A fixing frame is fixedly connected to the end of each of the two rotating rods that are close to each other. A through groove is opened on the bottom surface of the fixing frame. The detection tool body is located inside the fixing frame. Symmetrical compression springs are fixedly connected to the inner sidewall of the fixing frame. Positioning clamps are fixedly connected to the side of each of the two compression springs that are close to each other.

[0006] In a further embodiment, dampers are fixedly connected to the inner walls of both compression springs, and the sides of the two dampers that are close to each other are fixedly connected to the sides of the two positioning blocks that are far apart from each other.

[0007] In a further embodiment, a telescopic rod is fixedly connected to the front of the fixing frame, and a second bearing is fixedly embedded at the bottom end of the telescopic rod.

[0008] In a further embodiment, a pressure strip is fixedly connected to the bottom surface of the second bearing, and a nameplate is provided on the front of the main body of the testing tool.

[0009] In a further embodiment, the bottom surface of the compression spring is fixedly connected to symmetrical fixing blocks, and the bottom ends of both fixing blocks are fixedly connected to a level.

[0010] In a further embodiment, each of the two fixed plates is fixedly connected to a buckle plate on one side away from each other, and each of the two buckle plates has a buckle groove on its front side. The bottom surface of the base plate is fixedly connected to a symmetrical support seat, and the bottom surface of each of the two support seats is fixedly connected to an anti-slip pad.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device facilitates the inspection of the internal shape and verticality of large planes of castings through the inspection tool body. The fixed frame facilitates the placement of the inspection tool body, and the combination of compression springs and positioning clamps can reinforce the inspection tool body. The combination of the first bearing and the rotating rod allows for adjustment of the angle of the inspection tool body, facilitating multi-angle observation of whether the casting is vertical. Two spirit levels allow workers to easily observe the levelness of the inspection tool body, improving the efficiency of casting inspection. Attached Figure Description

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] 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 protection scope of the present utility model.

[0019] Please see Figure 1-4 In this utility model, a valve cover-type special wax film detection tool includes a base plate 1, on the upper surface of which are fixedly connected symmetrical fixing plates 2. First bearings 3 are fixedly embedded on the side of the two fixing plates 2 that are close to each other. Rotating rods 4 are fixedly connected to the inner rings of the two first bearings 3. A fixing frame 10 is fixedly connected to the end of the two rotating rods 4 that are close to each other. A through groove 5 is opened on the bottom surface of the fixing frame 10. A detection tool body 6 is provided inside the fixing frame 10. Symmetrical compression springs 7 are fixedly connected to the inner side wall of the fixing frame 10. Positioning clamps 8 are fixedly connected to the side of the two compression springs 7 that are close to each other. The detection tool body 6 facilitates the detection of the internal shape and whether the large plane of the casting is perpendicular. The fixing frame 10 facilitates the placement of the detection tool body 6. The cooperation of the compression springs 7 and the positioning clamps 8 can reinforce the detection tool body 6. The cooperation of the first bearings 3 and the rotating rods 4 can adjust the angle of the detection tool body 6, facilitating multi-angle observation of whether the casting is perpendicular.

[0020] Dampers 9 are fixedly connected to the inner walls of the two compression springs 7. The sides of the two dampers 9 that are close to each other are fixedly connected to the sides of the two positioning clamps 8 that are far from each other. A telescopic rod 11 is fixedly connected to the front of the fixing frame 10. A second bearing 12 is fixedly embedded at the bottom of the telescopic rod 11. A pressure strip 13 is fixedly connected to the bottom surface of the second bearing 12. A nameplate 16 is provided on the front of the testing tool body 6.

The cooperation of the anti-slip pads 20 and support seats 19 makes it possible to place the device stably and prevent the device from sliding.

[0022] The working principle of this utility model is as follows: In use, the device is first placed stably in a suitable position by using the anti-slip pad 20 and the support base 19. After the casting is produced, the main body 6 of the inspection tool is placed inside the valve cover casting to check if the large plane is flush with the inner hole. Then, the large plane is checked to ensure that it is parallel to the inspection tool without gaps. Next, the corresponding casting is placed inside the main body 6 of the inspection tool. The fixing bracket 10 is used to facilitate the placement of the main body 6 of the inspection tool. The main body 6 of the inspection tool is reinforced by the combination of the compression spring 7 and the positioning clamp 8. The angle of the main body 6 of the inspection tool can be adjusted by the combination of the first bearing 3 and the rotating rod 4, which facilitates multi-angle observation of whether the casting is vertical. The two level rulers 15 make it easy for the staff to observe the levelness of the main body 6 of the inspection tool, thus improving the inspection efficiency of the casting.
