Description

Technical Field

[0001] The utility model relates to the technical field of casting measurement and detection tools, in particular to a measurement and detection mechanism for the deformation of an aluminum alloy casting wheel hub blank. Background Art

[0002] Automobile wheel hubs are widely made of aluminum alloy, among which casting is the most common. During the production of aluminum alloy casting blanks, due to the change of the cooling gradient, it is easy to cause the aluminum alloy casting blank of the automobile wheel hub to wrap the mold too tightly, resulting in an increase in tensile force. When demolding, the aluminum alloy casting blank of the automobile wheel hub is prone to deformation, which will directly affect the production efficiency of subsequent machining. The main manifestations are as follows: After the deformed aluminum alloy casting blank of the automobile wheel hub is clamped, the swing is too large, which will cause poor dynamic balance and dimensional tolerance of the product. In severe cases, it is also easy to cause safety accidents such as crashing and tool breakage.

[0003] The existing detection mechanism for testing the deformation of aluminum alloy casting blanks of automobile wheel hubs includes a cross bridge ruler. The specialization of this cross bridge ruler is very single. A corresponding one needs to be equipped for each product, and corresponding drawings need to be issued for each product for measurement. Over time, the drawings are easy to lose and prone to errors. Therefore, a measurement and detection mechanism for the deformation of an aluminum alloy casting wheel hub blank is proposed.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements.

[0025] Please refer to Figures 1-3, A measuring and detecting mechanism for the deformation of an aluminum alloy cast wheel hub blank, including a main scale 1, a scale 7 printed on the main scale 1, and a main cursor 3. A slide bar 2 is horizontally installed on the main scale 1, and a sliding sleeve 6 is slidably connected to the slide bar 2, so that the sliding sleeve 6 can slide horizontally above the main scale 1. A limiting component is arranged between the sliding sleeve 6 and the upper surface of the main scale 1 for positioning the sliding sleeve 6. Among them, an installation groove 10 is opened at the bottom of the sliding sleeve 6, and a buffer spring 12 is fixedly installed on the inner top wall of the installation groove 10. Among them, the limiting component is arranged between the end of the buffer spring 12 far from the inner wall of the installation groove 10 and the upper surface of the main scale 1. Among them, the limiting component includes a limiting convex block 11 fixedly installed at the end of the buffer spring 12 far from the inner wall of the installation groove 10, and a friction plate 13 horizontally installed on the upper surface of the main scale 1. Among them, the limiting convex block 11 is in frictional connection with the friction plate 13, so that the limiting convex block 11 can maintain a downward movement trend through the elastic force of the extension of the buffer spring 12 until it is in frictional connection with the friction plate 13, so as to achieve the effect of limiting the sliding sleeve 6, and further enable the sliding sleeve 6 to stably move horizontally on the main scale 1 and achieve the effect of being fixed at the required scale. An installation cylinder 4 is installed on the top of the sliding sleeve 6, and the main cursor 3 is movably connected to the inside of the installation cylinder 4. Among them, a communication hole 15 is opened in the inside of the installation cylinder 4. Among them, the main cursor 3 is movably connected to the inside of the installation cylinder 4 through the communication hole 15. Among them, a limiting groove 16 is opened in the front-back direction on the inner top wall of the communication hole 15, and a limiting slider 14 is installed on the upper surface of the main cursor 3. Among them, the limiting slider 14 is movably connected to the limiting groove 16. By moving the sliding sleeve 6, the main cursor 3 can stably adjust its position on the main scale 1. By setting two main cursors 3 on the main scale 1, the measuring and detecting mechanism can stably measure the length of the wheel hub. Expansion components are hinged at both ends of the main scale 1 for expanding the measuring length. Among them, the expansion component includes a sub-scale 8 hinged at both ends of the main scale 1 and a sub-cursor 9 movably connected to the sub-scale 8. Thus, when the length of the main scale 1 is not enough, the sub-scale 8 can be rotated to a position horizontal with the main scale 1, and then the length of the wheel hub can be measured through the sub-cursor 9, so that the length of the measuring and detecting mechanism can be easily adjusted, and further achieve the effect of adapting to the measurement of aluminum alloy wheel hub castings of various sizes.

[0026] In this embodiment, a limiting block 5 is installed at the front end of the main cursor 3. Among them, the size of the limiting block 5 is larger than the inner diameter of the communication hole 15, so that the limiting block 5 can effectively prevent the main cursor 3 from falling off the inside of the installation cylinder 4, so as to achieve the effect of ensuring the integrity of the measuring and detecting mechanism.

[0027] Working principle: When measurement is required, the main cursor 3 is moved horizontally. Through the scales on the two main cursors 3 and the main scale 1, accurate measurement can be achieved. When the measurement length is insufficient, the secondary scale 8 can be rotated to a horizontal position with the main scale 1, and then the length between the main cursor 3 and the secondary cursor 9 can be used to measure a longer hub.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
