Abstract
Description
Technical Field
[0001] This utility model belongs to the field of detection equipment technology, and in particular relates to a detection device that protects sensors from impact. Background Technology
[0002] In the field of mechanical automation equipment, it is necessary to automatically detect whether a workpiece has passed through a certain station in order to complete automated processes such as counting. At present, there are many workpiece inspection devices, but due to their structural limitations, they are generally used for workpieces of fixed size and shape. However, when inspecting irregular workpieces or workpieces with inconsistent shapes, the incompatibility of the detection range will cause damage to the inspection equipment. This requires increasing the detection range of the sensing device and improving the detection performance of the sensor so that it can effectively detect workpieces of any size. Utility Model Content
[0003] The purpose of this invention is to improve upon the shortcomings of existing technologies by providing a protective impact detection device that can detect the presence or absence of workpieces of various sizes, does not require increased sensor performance, has a wide range of applications, a simple structure, and low cost.
[0004] The purpose of this utility model is achieved as follows: a protective impact detection device includes an equipment mounting surface, characterized in that a sliding sleeve moves through the equipment mounting surface and can move up and down on the equipment mounting surface; a shaft retaining spring is provided at the upper end of the sliding sleeve protruding from the equipment mounting surface; the upper part of the impact rod sleeve is threaded into the lower part of the sliding sleeve; the impact rod is movably installed inside the impact rod sleeve; a boss is provided at the upper end of the impact rod, the diameter of which is larger than the inner diameter of the impact rod sleeve; a workpiece contact fixture is provided at the lower end of the impact rod; and a proximity sensor is provided at the top of the sliding sleeve.
[0005] To further achieve the purpose of this utility model, a bushing may be installed at the contact point between the equipment mounting surface and the sliding sleeve.
[0006] To further achieve the purpose of this utility model, the outer diameter of the striker sleeve may not be greater than the outer diameter of the sliding sleeve.
[0007] Compared with existing technologies, this invention has the following significant features and positive effects: This invention uses a sliding sleeve movably mounted on the equipment mounting surface, and a strike rod movably mounted inside a strike rod sleeve. The strike rod sleeve is clamped inside the sliding sleeve. This allows for the inspection of small workpieces, where the workpiece contacts and pushes against the workpiece contact fixture. The strike rod's movement within the sliding sleeve and the cavity inside the strike rod sleeve allows for short-distance vertical movement and can trigger the top proximity sensor. When the workpiece is large and requires a long-distance ejection, the top of the strike rod approaches the proximity sensor inside the sliding sleeve, simultaneously pushing the sliding sleeve, strike rod sleeve, and strike rod upwards, preventing equipment damage due to exceeding the detection range. This invention broadens the detection range, adapting to the inspection of workpieces of different sizes and shapes, achieving multi-purpose functionality, avoiding increased inspection costs, and protecting the inspection equipment during the inspection process from damage to the sensing elements.

[0012] A protective impact detection device, referring to Figure 1 The sliding sleeve 3 moves through the equipment mounting surface 1. A bushing 2 is provided where the sliding sleeve 3 passes through the equipment mounting surface 1. The sliding sleeve 3 can move up and down within the bushing 2 on the equipment mounting surface 1. A shaft retaining spring 6 is provided at the upper end of the equipment mounting surface 1 to ensure that the sliding sleeve 3 does not slip. A proximity sensor 5 is provided at the top inside the sliding sleeve. The upper part of the impact rod sleeve 4 is threaded into the lower part of the sliding sleeve 3. The impact rod 7 is movably installed inside the impact rod sleeve 4, with the upper end of the impact rod 7 protruding from the impact rod sleeve. The top of the tube 4 is provided with a boss, the diameter of which is larger than the inner diameter of the impact rod sleeve 4. The boss is used to prevent the impact rod 7 from coming out of the impact rod sleeve 4. The bottom of the impact rod 7 is connected to a workpiece contact fixture 8. The impact rod 7 can move up and down a small distance in the cavity formed inside the sliding sleeve 3 and the impact rod sleeve 4, and can make the top proximity sensor 5 light up. When a large distance is required to be ejected, the top of the impact rod 7 approaches the proximity sensor 5 inside the sliding sleeve 3, and at the same time the sliding sleeve, the impact rod sleeve and the impact rod as a whole are ejected upward.
[0013] When using this invention, the device drives the mounting surface 1 to descend a certain distance and then rise again. Each descent determines whether there is a workpiece at the station. If there is a workpiece at the station, the workpiece will contact the workpiece contact fixture 8 when the mechanism descends, lifting the workpiece contact fixture 8 and the impact rod 7 together. When the top of the impact rod 7 approaches the proximity sensor 5, the proximity sensor 5 outputs a sensing signal. When there is a workpiece exceeding the size limit at the station, the stroke of the impact rod 7 within the sliding sleeve 3 and the impact rod sleeve 4 is insufficient. At this time, the impact rod 7 still approaches the proximity sensor 5 to trigger the output signal, but the impact rod 7 will strike the sliding sleeve 3, lifting the entire mechanism without affecting the signal output. When the detection is completed, the device drives the mounting surface 1 to rise, and the mechanism returns to its initial state by its own weight.
