DETAILED DESCRIPTION OF THE EMBODIMENTS
[0028] The following further describes the present utility model in detail with reference to the attached Figures 1 - 4 drawings.
[0029] Please refer to the drawings in the specification Figures 1 - 4, an embodiment provided by the present utility model: a guide pin length detection device, including a device main body 1, an electric push rod 2 is connected above the device main body 1, and a top plate 3 is connected above the electric push rod 2. By cooperating the electric push rod 2 with the top plate 3, the linkage plate 5 and the bottom plate 7 are driven to perform stable lifting, facilitating detection. A connecting rod 4 is connected to the center of the top plate 3, a linkage plate 5 is connected below the connecting rod 4, a first spring 8 is connected below the linkage plate 5, and the bottom plate 7 is driven to reset by the first spring 8 to ensure repeated detection. The bottom plate 7 is connected below the first spring 8, and a measuring rod 6 is connected above the bottom plate 7 to check the size protruding beyond the specified size by using the measuring rod 6;
[0030] A clamping block 9 is arranged below the bottom plate 7, a convex block 10 is connected to the center of the clamping block 9, and a stabilizing rod 11 is connected to the outside of the clamping block 9. The clamping block 9 is stably moved by the stabilizing rod 11. A second spring 12 is also connected to the outside of the clamping block 9. A support plate 14 is arranged below the clamping block 9, and a storage box 13 is arranged below the support plate 14. The qualified guide pins are stored by using the storage box 13 to improve the access efficiency. A grasping plate 15 is connected to the right side of the support plate 14, and a third spring 16 is connected to the left side of the grasping plate 15. The grasping plate 15 is driven to reset by the third spring 16 for convenient use.
[0031] Working principle: When in use, first, place the guide pin into the center of the device main body 1. Since a conical slope is provided at the top of the clamping block 9, when the guide pin is placed into the device main body 1, it will squeeze the clamping block 9, causing the clamping block 9 to move outward. During the movement, the stabilizing rod 11 slides inside the device main body 1 to ensure the parallel movement of the clamping block 9. Then, under the extrusion of the second spring 12 and the friction of the convex block 10, the guide pin is ensured to be stable in the center;
[0032] Similarly, after the guide pin is fixed, turn on the switch of the electric push rod 2, so that the top plate 3 drives the linkage plate 5 to descend through the connecting rod 4, and then the linkage plate 5 drives the bottom plate 7 to descend until it fits against the top of the guide pin. If the size of the guide pin is qualified, pull the pull ring on one side of the grasping plate 15, so that the grasping plate 15 drives the support plate 14 to slide. After the guide pin loses the bottom support, it falls into the interior of the storage box 13. When the guide pin is too long, it will squeeze the bottom plate 7, causing the bottom plate 7 to rise, and then driving the measuring rod 6 to rise. At this time, the staff can check the size of the measuring rod 6 to know the protruding size of the guide pin.
[0033] It should be added that the electric push rods 2 are symmetrically distributed on both sides of the device main body 1. The electric push rod 2 and the top plate 3 are of an integrated lifting structure. The top plate 3 and the linkage plate 5 are integrally installed through the connecting rod 4. By cooperating the electric push rod 2 with the top plate 3, the linkage plate 5 is driven to perform lifting at a fixed height, facilitating automatic measurement work.
[0034] It should be noted that the linkage plate 5 forms a spring reset structure with the base plate 7 through the first spring 8. Measuring rods 6 are symmetrically distributed on both sides above the base plate 7. The measuring rods 6 are connected to the linkage plate 5 by a sliding connection. The linkage plate 5 cooperates with the base plate 7 to support the top of the guide pin. When the guide pin is long, the measuring rod 6 will be lifted to complete the rapid detection work.
[0035] It should be noted that the connection between the clamping block 9 and the stabilizing rod 11 is a hot-melt connection, and the connection between the stabilizing rod 11 and the device body 1 is a sliding connection. The clamping blocks 9 are evenly and equidistantly distributed around the center of the device body 1. There are three groups of clamping blocks 9, which are automatically clamped and fixed by the clamping blocks 9, and there is no need for manual fixing by the staff.
[0036] It should be noted that the protrusions 10 are evenly and equidistantly distributed on the inner side of the clamping block 9, the protrusions 10 fit tightly against the surface of the guide pin, and the clamping block 9 forms a spring reset structure with the device body 1 through the second spring 12. The protrusions 10 cooperate with the second spring 12 so that the clamping block 9 fits tightly around the guide pin to ensure firm fixation.
[0037] It should be noted that a pull ring is provided on the outer side of the grab plate 15, and the grab plate 15 forms a spring reset structure with the device body 1 through the third spring 16. The grab plate 15 and the support plate 14 are connected by hot melt connection, and the support plate 14 and the device body 1 are connected by sliding connection. The support plate 14 is driven to move by the grab plate 15, and the guide pins that meet the size can be quickly collected.
[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
