Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece processing, in particular to a processing and positioning device for a jack guide sleeve. Background Art

[0002] The jack guide sleeve is a crucial component of the jack. Typically made of high-strength metal and cylindrical in shape, it provides precise guidance for the jack's piston rod, ensuring linear motion during extension and retraction, minimizing deflection and wear. The sleeve's interior is precision-machined to a smooth surface to reduce friction. It also effectively prevents dust and impurities from entering the jack, protecting internal components. For example, during car repairs, a high-quality guide sleeve ensures the jack maintains stable support for the vehicle. Positioning devices are typically used during the sleeve's machining process.

[0003] The positioning device is usually composed of sensors, controllers and actuators. The sensors are responsible for detecting the position information of the target object. Common ones include photoelectric sensors, laser sensors, etc. The controller receives the signal from the sensor, analyzes and processes it, and calculates the deviation from the set position. The actuator adjusts the position of the target object according to the instructions of the controller. Its principle is based on feedback control, which continuously monitors and corrects position deviations. The positioning device can accurately control the relative position of the tool and the workpiece, thereby achieving high-precision processing.

[0004] The existing positioning device will have unstable positioning when performing positioning operations on the jack guide sleeve. For example, the positioning plate will cause the jack guide sleeve to offset or warp during positioning, which will cause damage to the jack guide sleeve in subsequent processing; and the existing positioning device has insufficient adaptability to jack guide sleeves of different calibers, which will lead to unstable fixation problems in the processing of jack guide sleeves of different calibers.
