Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical detection and relates to a pin shaft detection platform for engineering machinery. Background Art

[0002] Pins are common components in the mechanical field. To ensure smooth assembly with other components, pin dimensions, such as height and slot diameter, must be within specified ranges. Therefore, testing and screening pin dimensions are essential steps in the pin production process.

[0003] The existing pin shaft detection device uses a pushing structure to push the pin shaft to a detection ring that meets the shaft diameter to detect whether the shaft diameter of the pin shaft is standard. During the detection process, whether the pin shaft meets the standard is judged by observing whether it can pass through the inside of the detection ring. However, in the actual detection process, it is inevitable that two sections of pin shafts with inconsistent shaft diameters will appear. When the end of the pin shaft with a smaller shaft diameter has entered the detection ring, the pushing structure can easily cause the pin shaft and the detection ring to get stuck, making it difficult to extract the pin shaft from the detection ring. Utility Model Content

[0004] The purpose of the utility model is to provide a pin shaft detection platform for engineering machinery, which can solve the problems raised in the background technology.

[0006] The support plate is provided with a spring telescopic rod, the upper ends of the spring telescopic rods are jointly provided with an upper plate, the upper plate is provided with a lower plate, and the lower plate is provided with a rectangular through hole adapted to the push block.

[0007] Preferably, a second connecting plate is provided at one end of the round rod, and a second supporting ring is commonly provided on the two second connecting plates.

[0008] Preferably, a first long ring is provided near one end of the round rod, a first connecting plate is provided on the first long ring, and a first supporting ring is provided between the two first connecting plates.

[0009] Preferably, one of the first long rings is in sliding connection with a round rod, and another round rod is provided with a threaded portion, and the threaded portion is screwed to the other first long ring.

[0012] The positive progress of this application is:

[0013] The advantages of the engineering machinery pin shaft detection platform provided by the embodiment of the utility model are as follows:

[0014] 1. When the pin needs to be inspected, one end of the pin is inserted into the inspection ring. If it can pass the inspection ring smoothly, it is qualified. If the pin is stuck between the inspection ring, the pneumatic cylinder will contract, driving the V-shaped rod to move, thereby driving the inspection ring and the bump to move. During the movement of the bump, it contacts the rectangular through-hole and compresses the spring telescopic rod, causing the lower plate to move downward, thereby driving the upper plate to move downward and contact the pin, and pushing out the pin stuck in the inspection ring.
