Description

Technical Field

[0001] The utility model relates to the technical field of machining, and particularly relates to a waterproof electronic edge finder. Background Art

[0002] An edge finder is a detection tool widely used in numerical control machining. Its main function is to accurately determine the center position of the workpiece to be machined. In the manufacturing and processing industries, the positioning accuracy of workpieces is crucial for product quality. Therefore, as an auxiliary device to improve machining accuracy, the edge finder plays an important role. The working principle of traditional edge finders is to measure the edge position of an object through a mechanical device. For example, a mechanical edge finder measures the edge position of an object through a cursor, a transmission device, and a fixing device. When the cursor contacts the edge of the object, the transmission device converts the position of the cursor into a change in length or angle, thereby achieving the measurement of the edge position.

[0003] In the prior art, during the use of machining, since there are often holes in the sound - emitting part of the sound and light, it is easy to let water or oil enter during measurement, affecting the use of the circuit and the measurement accuracy. Therefore, we make improvements and propose a waterproof electronic edge finder. Summary of the Utility Model

[0029] Such as Figures 1-6As shown in the figure, this embodiment proposes a waterproof electronic edge finder, which includes an edge finder 1. A metal body 2 is provided at the outer end of the edge finder 1. A measuring ball 3 is provided at the upper end of the metal body 2. A spring pull rod 4 is provided at the center of the measuring ball 3. Three sound - emitting channel grooves 18 are provided at the outer end of the spring pull rod 4. The three sound - emitting channel grooves 18 are inclined grooves that are wider at the top and narrower at the bottom. A return spring 5 is provided at the lower end of the spring pull rod 4. A circuit negative - pole ring 6 is provided at the lower end of the return spring 5. A main board 7 is provided at the outer end of the circuit negative - pole ring 6. A warning light 8, a buzzer 9 and a sensor 10 are provided at the inner end of the main board 7. A positioning seat 11 is provided at the lower end of the main board 7. A positioning groove 13 is provided at the outer end of the positioning seat 11. A transparent ring sleeve 12 is provided at the upper end of the positioning groove 13. A transparent body 14 is provided at the outer end of the transparent ring sleeve 12. A battery slot 15 is provided at the lower end of the positioning seat 11. A battery pack 16 is provided at the inner end of the battery slot 15. A spring base 17 is provided at the lower end of the battery pack 16.

[0030] Through the mechanical structure composed of the measuring ball 3, the spring pull rod 4 and the return spring 5, the edge contact can be accurately sensed. And the circuit negative - pole ring 6, the warning light 8, the buzzer 9 and the sensor 10 form a complete set of feedback mechanisms, ensuring the high sensitivity and instant response ability of the device for object detection.

[0031] Through physical contact combined with electronic feedback, accurate edge recognition is achieved. Once the measuring ball 3 touches the workpiece, the operator is immediately reminded by light and sound, improving work efficiency.

[0032] The three sound - emitting channel grooves 18 are embedded and installed on the inner surface of the upper end of the metal body 2. The tail end of the metal body 2 is thread - connected with the spring base 17. The upper and lower parts of the metal body 2 are thread - connected through the transparent body 14.

[0033] The three sound - emitting channel grooves 18 facilitate the emission of sound and can pass through the head end of the metal body 2.

[0034] The positioning seat 11 is fixed at the inner end of the metal body 2. The upper end of the positioning seat 11 is adhesively bonded to the main board 7. The inner end of the main board 7 is respectively welded to the buzzer 9, the sensor 10, the warning light 8 and the circuit negative - pole ring 6. The upper end of the circuit negative - pole ring 6 is movably connected to the return spring 5.

[0035] The upper end of the return spring 5 is movably connected to the spring pull rod 4. The spring pull rod 4 is fixedly connected to the measuring ball 3. The upper ends of the three sound - emitting channel grooves 18 penetrate through the outer surface of the upper end of the metal body 2. The cross - sectional radius of the measuring ball 3 is smaller than the distance between the center of the metal body 2 and the outer end of the sound - emitting channel groove 18.

[0036] The design of the return spring 5 allows the measuring ball 3 to deform when subjected to an external force and at the same time has the ability to quickly return to its original position.

[0037] The transparent ring sleeve 12 is sleeved on the outer end of the main board 7, the positioning groove 13 is embedded in the inner surface of the lower end of the transparent ring sleeve 12, and the transparent ring sleeve 12 is attached to the inner end of the transparent body 14.

[0038] The positioning groove 13 and the positioning seat 11 are mutually engaged, and the main board 7 is connected to the battery pack 16 through the positioning seat 11.

[0039] When this application is in use: the measuring ball 3, the spring pull rod 4, the return spring 5, the main board 7, the transparent ring sleeve 12, the positioning seat 11 and the battery pack 16 are sequentially placed in the metal body 2. The transparent body 14 is used to form an open circuit on the metal body 2, and then after installing the machine (the machine is a metal part), a circuit is formed. The front-end measuring ball 3 is used to touch the workpiece. When the workpiece is contacted, the product circuit is triggered, so that the warning light 8 emits light through the transparent ring sleeve 12 and the transparent body 14, and the buzzer 9 makes a sound, and the sound is transmitted through the three groups of sound-emitting channel grooves 18, thereby prompting the operator of the current position coordinates. Utilizing the resilience of the return spring 5, it is convenient for the measuring ball 3 to rebound to the initial position, and the setting of the three groups of sound-emitting channel grooves 18 can ensure that the measuring ball 3 is accurately placed at the head end of the metal body 2, further improving the accuracy of edge finding;

[0040] At the same time, due to the sealing performance of the transparent ring sleeve 12 in the metal body 2, it can prevent oil or water from entering the edge finder 1 and causing damage to the main board. And with the transparent body 14 as the open circuit, when the product is installed on the machine, the circuit is formed to trigger the sound and light operation.

[0041] The above embodiments are only used to illustrate the present invention rather than to limit the technical solutions described in the present invention.
