Abstract

The invention discloses a hydraulic type clamp used for machining antenna brackets of a tablet personal computer. The hydraulic type clamp comprises a left supporting seat, a right supporting seat, a fixing plate, a locating plate, a clamping head and a pressure mechanism; the two ends of the fixing plate are fixedly connected with the left supporting seat and the right supporting seat correspondingly; the locating plate is fixedly connected with the fixing plate; a hydraulic oil hole is formed in one side surface of the pressure mechanism; one face, provided with clamping teeth, of a rack faces an arc-shaped clamping claw, the arc-shaped clamping claw is installed on the lower surface of a movable plate, and the front end of the arc-shaped clamping claw is embedded in the clamping teeth of the rack; a vertical clamping groove is formed in the inner side surface of a sliding block, and the sliding block is connected with a guiding strip through the vertical clamping groove in a clamping mode and is fixedly connected with the rack; and the lower end of a limiting screw rod penetrates through a pushing block from top to bottom and then is embedded in a center through hole of a pushing rod of a top plate air cylinder, and the limiting screw rod is sleeved with a limiting nut. According to the hydraulic type clamp used for machining the antenna brackets of the tablet personal computer, the stroke of the top plate air cylinder can be limited by arranging a limiting stud and the limiting nut, so that the rising stoke of the movable plate is in accordance with need, each rising stroke of the movable plate is fixedly consistent, and the machining precision is ensured.

Description

technical field

[0001] The invention relates to a hydraulic clamp for processing an antenna bracket of a tablet computer, and relates to the field of high precision machining. Background technique

[0002] Smartphones are the most widely used entertainment and communication devices, and their update speed is relatively fast. Therefore, smartphone manufacturers have also put forward higher requirements. Smartphone components are inseparable from machine tool equipment, and machine tool fixtures are one of the important technological equipment to ensure machine tool processing quality, improve production efficiency, and reduce labor intensity. However, there are many problems in how to stably and effectively position the workpiece during processing. .

[0003] The traditional CNC fixtures mostly use simple fixtures and positioning pins for positioning operations, and are loaded and unloaded by workers for positioning. This will lead to unstable positioning of the workpiece, t...
